Referring to fig. 1 and 2, an electronic viewfinder 110 provided in an embodiment of the present application includes a housing 1101 and an adjustment mechanism 1111. A lens 1103 is provided in the housing 1101. The lens 1103 includes a lens 1105. An adjustment mechanism 1111 is coupled to housing 1101. The adjustment structure 1111 includes a first thumbwheel 1113, a second thumbwheel 1115, and a transmission 1117. The transmission 1117 connects the first thumb wheel 1113 with the second thumb wheel 1115. A second thumbwheel 1115 is connected to the lens 1105. The second wheel 1115 rotates to move the lens 1105 along the optical axis L of the lens 1103. The transmission mechanism 1117 is configured to convert the rotation of the first dial 1113 into the rotation of the second dial 1115, so as to drive the lens 1105 to move along the optical axis L of the lens 1103 to adjust the diopter of the electronic viewfinder 110. In one embodiment, the rotational plane of the first pulsator 1113 is perpendicular to the rotational plane of the second pulsator 1115.

Illustratively, the transmission mechanism 1117 is configured to convert the rotation of the first pulsator 1113 into a linear motion, and simultaneously convert the linear motion into the rotation of the second pulsator 1115. The rotation of the second pulsator 1115 may be converted into movement along the optical axis.

Illustratively, the first pulsator 1113 is located outside the housing 1101, and the second pulsator 1115 is located inside the housing 1101.

The electronic viewfinder 110 converts the rotation of the first dial wheel 1113 into the rotation of the second dial wheel 1115 through the transmission mechanism 1117, and further drives the lens 1105 to move along the optical axis L of the lens 1103 so as to adjust the diopter of the electronic viewfinder 110, so that the electronic viewfinder 110 capable of adjusting the diopter can adapt to the requirements of different users.

Specifically, in the embodiment shown in fig. 1 and 2, by dialing the first thumbwheel 1113 to rotate, the adjustment mechanism 1111 is enabled to move back and forth in the axial direction M of the first thumbwheel 1113. In this case, the second thumb wheel 1115 can be correspondingly rotated with the movement of the adjustment mechanism 1111, thereby causing the lens 1105 to move back and forth along the optical axis L. The first wheel 1113 may be a component exposed outside the electronic viewfinder 110, and a user may rotate the first wheel 1113 to drive the second wheel 1115 to rotate, so as to drive the lens 1103 to move to adjust the diopter of the electronic viewfinder 110. In fig. 2, 4 lenses 1105 are provided in the lens element 1103 to form a lens group. In other embodiments, the number of the lenses 1105 in the lens 1103 may be other numbers, such as 1, 2, 3 or more than 4, and is not limited herein.

In the present embodiment, referring to fig. 1 again, an observation unit 1102 is connected to the front side of the housing 1101, and an observation window 1104 is opened in the observation unit 1102. The lens 1103 may protrude forward from the viewing window 1104. A portion of the first thumb wheel 1113 is exposed from the sidewall of the observation portion 1102, and another portion of the first thumb wheel 1113 is located inside the observation portion 1102, so that the user can operate the device conveniently, and the portion of the first thumb wheel 1113 located inside the observation portion 1102 can be protected. The front side of the housing 1101 refers to a side facing the user when the user views through the electronic viewfinder 110.

It is to be appreciated that in other embodiments, the first thumbwheel 1113 may also be entirely exposed from the viewing portion 1102, which may facilitate a user in manipulating the first thumbwheel 1113 from different orientations.

Referring to fig. 3 to 6, in some embodiments, the transmission mechanism 1117 includes a rotating shaft 1121 and a sleeve 1123. The rotation shaft 1121 includes a first end 1125 and a second end 1127. The first end 1125 is fixedly coupled to the first thumb wheel 1113. The sleeve 1123 sleeves the second end 1115. The sleeve 1123 is provided with a driving arm 1129. A drive arm 1129 is connected to the second thumbwheel 1115. When the first wheel 1113 rotates along the first direction, the rotating shaft 1121 is driven to rotate, so as to drive the sleeve 1123 to move along the optical axis L parallel to the lens 1103. The sleeve 1123 drives the driving arm 1129 to rotate the second wheel 1115 in a second direction when moving parallel to the optical axis L of the lens 1103. In this way, it is simply achieved that the movement of the lens 1105 is indirectly controlled by the first jog wheel 1113.

Specifically, in the embodiment shown in fig. 3 and 4, with the first thumbwheel 1113 rotated in a first direction, the sleeve 1123 can be entrained to move in a direction away from the first thumbwheel 1113. In this case, the second thumb wheel 1115 is rotated in the second direction by the driving arm 1129.

It can be understood that the structure can be simplified and the operation can be easily performed by converting the rotation of the first thumb wheel 1113 into the linear movement of the rotating shaft 1121 and the sleeve 1123, and further into the circular movement of the second thumb wheel 1115.

Referring to fig. 6 and 7, in some embodiments, the second thumb wheel 1115 has a thumb block 1131 on an outer circumferential surface thereof. The end of the drive arm 1129 is provided with a stop 1133. The stopper 1133 is configured to abut against one side of the toggle block 1131. The sleeve 1123 drives the stopper 1133 to drive the dial block 1131 to rotate when moving along the optical axis L parallel to the lens 1103, and further drives the second dial wheel 1115 to rotate along the second direction. Thus, the sleeve 1123 can drive the second dial wheel 1115 to rotate.

Specifically, in the case that the sleeve 1123 moves in the direction away from the first dial wheel 1113, the stopper 1133 abuts against one side of the dial block 1131, so that the stopper 1133 drives the dial block 1131 to move, and the dial block 1131 will rotate in the axial direction of the second dial wheel 1115, thereby driving the second dial wheel 1115 to rotate.

In some embodiments, a first resilient member (not shown) is coupled to second thumb wheel 1115. The first elastic member is used to drive the second thumb wheel 1115 to rotate in the fourth direction when the first thumb wheel 1113 rotates in the third direction. The first direction is opposite to the third direction. The second direction is opposite to the fourth direction. As such, the second paddle wheel 1115 may have a reset function.

Specifically, in the case where the second thumb wheel 1115 rotates in the second direction, the first elastic member may be compressed to generate an elastic force. When the first wheel 1113 rotates in the third direction (i.e., the direction opposite to the first direction), the first elastic member drives the second wheel 1115 to rotate in the fourth direction (i.e., the direction opposite to the second direction) by the restoring force, so that the lens 1105 can move back and forth along the optical axis L when the first wheel 1113 rotates back and forth. In one embodiment, the first resilient member is connected to the housing 1101 at one end and to the dial block 1131 or the second dial wheel 1115 at the other end.

In addition, the first elastic member may include a torsion spring, a coil spring, a leaf spring, or a spring. In other embodiments, the first elastic member may be omitted, and in particular, the stop 1133 on the driving arm 1129 may be directly sleeved on the toggle block 1131, and when the first toggle wheel 1113 rotates in the first direction and the third direction, the second toggle wheel 1115 may be driven to rotate back and forth in the second direction and the fourth direction. In such an embodiment, the rotating shaft 1121 may be threadedly coupled to the sleeve 1123, or another elastic member may be added to a side of the sleeve 1123 for driving the sleeve 1123 to move toward the first dial 1113.

Referring to fig. 4-6, in some embodiments, the electronic viewfinder 110 includes a spiral surface 1137 and a holding block 1139. A spiral surface 1137 is disposed on one of the outer periphery of second end 1127 and the interior of sleeve 1123, and a retaining block 1139 is disposed on the other of the outer periphery of second end 1127 and the interior of sleeve 1123. The spiral surface 1137 is coupled with the abutting block 1139, so that the rotation of the shaft is converted into the movement of the sleeve 1123 along the optical axis L parallel to the lens 1103. Thus, the replacement of the rotation of the first dial 1113 with the linear movement of the sleeve 1123 parallel to the optical axis L of the lens 1103 can be simply achieved.

Specifically, in the illustrated embodiment, the spiral surface 1137 is disposed on an outer circumferential surface of the second end 1127 and the abutment block 1139 is disposed within the sleeve 1123. The spiral surface 1137 extends along the axial direction of the rotating shaft 1121 on the outer peripheral surface of the second end 1127 as a whole. The support block 1139 is protruded from the inner wall surface of the sleeve 1123. With the sleeve 1123 disposed over the second end 1127 of the shaft 1121, the abutment blocks 1139 inside the sleeve 1123 abut against the surface of the spiral surface 1137. Under the condition that the first dial wheel 1113 drives the rotating shaft 1121 to rotate along the axial direction of the rotating shaft 1121, the abutting block 1139 can be driven to move relatively along the surface of the spiral surface 1137, and finally the sleeve 1123 can move along the optical axis L parallel to the lens 1103.

Additionally, it is understood that in other embodiments, the helical surface 1137 may be disposed within the sleeve 1123 and the retaining block 1139 may be disposed on the outer circumferential surface of the second end 1127. The specific principle is similar to that of the above embodiments, and is not described herein again.

Referring to fig. 4, 6 and 8, in some embodiments, sleeve 1123 is provided with a pilot hole 1141. The transmission 1117 includes a first guide post 1143. The length direction of the first guiding column 1143 is parallel to the optical axis L of the lens 1103. The sleeve 1123 is slidably mounted in the first guide post 1143 through the guide bore 1141. In this manner, smooth movement of the sleeve 1123 in the direction of the axis M is ensured.

Specifically, the axis M is parallel to the optical axis L of the lens 1103. It can be understood that the sleeve 1123 may shake while moving along the axis M, so that the sleeve 1123 is difficult to move smoothly and may deviate from the original moving direction, which affects the moving effect of the transmission mechanism 1117 to drive the second thumbwheel 1115. By providing the guide holes 1141 and the first guide posts 1143, movement of the sleeve 1123 may be guided, which may increase the smoothness of the sleeve 1123 as the sleeve 1123 moves. In one embodiment, the inner wall of the guide bore 1141 and the outer surface of the first guide post 1143 are smooth, which allows for less effort when moving the sleeve 1123 along the first guide post 1143.

Referring to fig. 3 to fig. 5, in some embodiments, an annular segment sensing portion 1145 is disposed on an outer circumferential surface of the rotating shaft 1121. The sensing section 1145 has a plurality of grooves 1147 along the circumference of the rotating shaft 1121. A spring 1149 is fixed to the housing 1101. The end of the spring 1149 is received in one of the grooves 1147. When the rotating shaft 1121 rotates, the ends of the elastic pieces 1149 are switched to be accommodated in different grooves 1147. Therefore, the rotating shaft 1121 can be kept at a specific position, a section sense during rotation can be provided for a user, and user experience is improved.

Specifically, in a case that the end of the elastic tab 1149 is received in one of the grooves 1147 of the rotating shaft 1121, the elastic tab 1149 can be engaged in the groove 1147, so that the rotating shaft 1121 is limitedly maintained at the current position. Since the position of the rotating shaft 1121 is fixed, the position of the sleeve 1123 is also fixed. Thus, the second thumbwheel 1115 can rotate and remain in a particular position. In the case of further rotating the first thumb wheel 1113, the end of the elastic sheet 1149 is pushed out of the current groove 1147 due to its elasticity and can be accommodated in the adjacent one of the grooves 1147, i.e. the lens 1105 can be adjusted from the current position and kept in another position by the rotation of the first thumb wheel 1113.

Referring to fig. 1 and 8, in some embodiments, actuator 1117 includes a first link 1151, and first link 1151 connects first thumbwheel 1113 to first end 1125. Therefore, the spatial position of the element can be conveniently adjusted.

Specifically, in the embodiment shown in fig. 1, the first thumb wheel 1113 is partially located outside the housing 1101, and the rotating shaft 1121 is located inside the housing 1101. It can be appreciated that by providing the first connection 1151, the position of the first thumb wheel 1113 on the housing 1101 can be adjusted, and the inconvenience of assembling the first thumb wheel 1113 and the rotating shaft 1121 due to too close distance can be avoided. In addition, since the first thumb wheel 1113 is partially exposed and often contacts the user, in some embodiments, the first thumb wheel 1113 is usually made of metal, and the rotating shaft 1121 and the first connecting member 1151 are located inside the electronic viewfinder 110 and are usually made of plastic, and the first thumb wheel 1113 can be connected to the rotating shaft 1121 through the conversion of the first connecting member 1151. Specifically, in one embodiment, a first connection block (not shown) and a second connection block (not shown) are respectively disposed on two sides of the first connection element 1151, the first connection block and the first dial wheel 1113 may be fixedly connected by interference fit, welding, bonding, and the like, and the second connection block and the first end 1125 of the rotation shaft 1121 may be fixedly connected by interference fit, welding, bonding, and the like. The rotating shaft 1121 may be an integrally formed structure, the first connecting member 1151 may be an integrally formed structure, and the sleeve 1123 may be an integrally formed structure.

Referring to fig. 3, 4 and 8, in some embodiments, first end 1125 is provided with a first support post 1153. The second end 1127 is provided with a second support post 1155. The electronic viewfinder 110 includes a first fixing plate 1157 and a second fixing plate 1159 mounted on the housing 1101. The first supporting post 1153 is rotatably inserted through the first fixing plate 1157. The second supporting post 1155 is rotatably inserted through the second fixing plate 1159. Thus, the rotation shaft 1121 can be smoothly rotated.

It can be understood that the first supporting column 1153 is rotated to penetrate through the first fixing plate 1157, and the second supporting column 1155 is rotated to penetrate through the second fixing plate 1159, so that the rotating shaft 1121 can be rotated stably along the axis M, and the shaking is avoided. In such an embodiment, first connector 1151 is fixedly coupled to first support post 1153.

Referring to fig. 8, in some embodiments, a first stopper 1161 is disposed on the first fixing plate 1157. The outer peripheral surface of the rotating shaft 1121 is provided with a second limiting block 1163. The first stopper 1161 and the second stopper 1163 are used to limit the rotation angle of the rotation shaft 1121 in the case of contact. In this way, the rotation shaft 1121 can be prevented from being excessively rotated to cause the pressing between the components.

Specifically, under the condition that the first limiting block 1161 contacts with the second limiting block 1163, the rotating shaft 1121 is blocked by the first limiting block 1161 and cannot rotate continuously, so that the user can be prompted that the first dial wheel 1113 has rotated to the limit position along the first direction or the third direction, and the condition that the rotating shaft 1121 is excessively rotated to cause mutual extrusion between elements can be avoided.

Referring to fig. 2 and 7, in some embodiments, a second link 1165 is coupled to the second thumb wheel 1115. Lens 1103 includes a lens barrel 1167 located within housing 1101. Lens 1103 is located in barrel 1167. When the second wheel 1115 rotates, the second connecting member 1165 is driven to drive the lens barrel 1167 to move along the optical axis L of the lens 1103 in the fifth direction. In this manner, the movement of the lens 1103 is driven by the entire movement of the lens barrel 1167, which is simple and easy.

Specifically, the bottom of the second thumb wheel 1115 is protruded with a ring portion 1114, the ring portion 1114 is opened with a notch 1116, the top of the second connecting member 1165 is provided with a protrusion 1118, and the protrusion 1118 is partially located in the notch 1116, so that when the second thumb wheel 1115 rotates, the ring portion 1114 can be driven to rotate, and the side wall of the notch 1116 can abut against the protrusion 1118 to further drive the second connecting member 1165 to rotate. In addition, the second thumb wheel 1115 and the second connecting piece 1165 may be locked by a screw, preventing separation between the second thumb wheel 1115 and the second connecting piece 1165. In the illustrated embodiment, the direction of rotation of the second thumb wheel 1115 is aligned with the direction of rotation of the second link 1165.

Referring to fig. 7, a push block 1119 is protruded from an outer peripheral surface of the second connecting member 1165, a bump 1120 is disposed on an outer surface of the lens barrel 1167, the push block 1119 abuts against one side of the bump 1120, and when the second connecting member 1165 rotates, the push block 1119 can push the bump 1120 to move along the rotating direction, so as to drive the lens barrel 1167 to move along the fifth direction.

Referring to fig. 2, in the illustrated embodiment, 4 lenses 1105 are disposed in the lens barrel 1167. The 4 lenses 1105 are fixed in a lens barrel 1167, the lens barrel 1167 is movably located in the housing 1101, the second connecting member 1165 can be received in a through hole (not shown) formed in the housing 1101, and the second thumbwheel 1115 outside the housing 1101 is connected with the lens barrel 1167 in the housing 1101 through the second connecting member 1165, so that on one hand, maintenance of the second thumbwheel 1115 is facilitated, and on the other hand, assembly between components is facilitated.

Referring to fig. 7, in some embodiments, a fixing member 1169 is disposed on an outer surface of a lens barrel 1167. The electronic viewfinder 110 includes a second elastic member 1171. The second resilient member 1171 abuts between the inner wall of the housing 1101 and the fixing member 1169. The second elastic member 1171 is used for driving the lens barrel 1167 to move along the sixth direction. The sixth direction is opposite to the fifth direction. In this way, the lens barrel 1167 can be moved in the other direction by the second elastic member 1171.

Specifically, the fifth direction and the sixth direction are both along the optical axis L of the lens 1103 or parallel to the optical axis L of the lens 1103, and referring to fig. 8, when the first dial 1113 rotates in the first direction and the barrel 1167 moves in the fifth direction along the optical axis L of the lens 1103, the second elastic member 1171 may be compressed to generate a restoring force for the second elastic member 1171. When the lens barrel 1167 needs to move in the sixth direction, the first dial 1113 rotates in the third direction, and the second elastic member 1171 drives the lens barrel 1167 to move in the sixth direction (i.e. the direction opposite to the fifth direction) by the restoring force, so that the lens 1105 can move back and forth along the optical axis L.

The second elastic member 1171 may include a torsion spring, a coil spring, a spring plate, or a spring, and in the illustrated embodiment, the second elastic member 1171 is a spring. In other embodiments, the second elastic member 1171 may be omitted, the push block 1119 of the second connecting member 1165 may be directly sleeved on the bump 1120, and when the first wheel 1113 rotates back and forth along the first direction and the third direction, the second wheel 1115 is driven to rotate back along the second direction and the fourth direction, and the lens barrel 1167 is driven to move back along the fifth direction and the sixth direction. Of course, in such an embodiment, a second resilient member 1171 may also be provided to increase the driving force.

Referring to fig. 7, in some embodiments, the electronic viewfinder 110 includes a second guide post 1173. A second guide post 1173 is attached within the housing 1101. The second guiding post 1173 is disposed through the second elastic member 1171 and the fixing member 1169. In this way, the extending and contracting direction of the second elastic member 1171 can be guided.

It can be understood that when the lens barrel 1167 moves back and forth along the optical axis L of the lens 1103, the second elastic member 1171 generates an elastic force parallel to the optical axis L. By providing the second guiding column 1173, the generated elastic force is not deflected to deflect the second elastic member 1171, thereby ensuring that the second elastic member 1171 can stably drive the lens barrel 1167.

In some embodiments, the electronic viewfinder 110 further includes a display 1175, and the display 1175 is located on the object side of the lens 1103. In this manner, the view displayed on the display 1175 can be observed through the lens 1103, and at the same time, the diopter of the electronic viewfinder 110 is adjusted by moving the lens 1105, so that different users can clearly observe the view displayed on the display 1175 through the electronic viewfinder 110.

Specifically, the display 1175 may be connected to a camera device via a flexible circuit board, the camera device includes an image sensor, and image data formed by the image sensor is transmitted to the display 1175 via the flexible circuit board for display.

Referring to fig. 14, a camera 1000 according to an embodiment of the present disclosure includes a main body 200 and the electronic viewfinder 110 according to any of the embodiments described above. The electronic viewfinder 110 is mounted on the main body 200.

In the shooting device 1000, the rotation of the first dial wheel 1113 is converted into the rotation of the second dial wheel 1115 through the transmission mechanism 1117, and then the lens 1105 is driven to move along the optical axis L of the lens 1103 so as to adjust the diopter of the electronic viewfinder 110, so that the electronic viewfinder 110 capable of adjusting the diopter can adapt to the requirements of different users.

Specifically, when the electronic viewfinder 110 views an image captured by the camera 1000, the first wheel 1113 can be rotated back and forth, and the position of the lens 1105 located in the housing 1101 can be adjusted by the cooperation of the second wheel 1115 and the transmission mechanism 1117, so that the lens 1105 can move back and forth along the direction of the optical axis L, thereby achieving the effect of diopter change.

In the illustrated embodiment, the imaging device 1000 is a camera. In other embodiments, the camera 1000 may be a video camera or other device with camera functions.

Referring to fig. 9 to 12, an adjusting device 100 according to an embodiment of the present disclosure includes an elastic member 10, a bracket 20, at least two supporting members 30, and a toggle member 40. The elastic member 10 includes at least two first abutting portions 11. The bracket 20 includes a supporting member 21, and the elastic member 10 is disposed on the supporting member 21.

The abutting pieces 30 are arranged corresponding to the first abutting portions 11 one by one, and the abutting pieces 30 abut against the corresponding first abutting portions 11 respectively. The toggle member 40 is rotatably disposed on the support 20, the elastic member 10 abuts against the toggle member 40 through the at least two abutting members 30, so that the toggle member 40 is positioned by the abutting members 30 after rotating a preset angle relative to the support 20, and the at least two abutting members 30 are uniformly distributed at intervals along the circumferential direction of the toggle member 40.

In the adjusting device 100, the elastic member 10 can provide a supporting force to the toggle member 40 through the supporting member 30, so that the toggle member 40 can be kept stable in a rotating process or a static state, and the influence of shaking of the toggle member 40 on the normal use of the adjusting device 100 can be avoided.

Specifically, in the illustrated embodiment, the toggle member 40 is a circular ring, and the elastic member 10 provides a biasing force along the radial direction of the toggle member 40 by the biasing force provided by the biasing member.

The at least two abutting pieces 30 are uniformly distributed at intervals along the circumferential direction of the stirring piece 40, on one hand, when the stirring piece 40 is in a static state, the elastic piece 10 abuts against the stirring piece 40 through the at least two abutting pieces 30, and provides radial acting force of the abutting pieces 30 for the stirring piece 40, so that the stirring piece 40 is prevented from shaking. On the other hand, when the toggle member 40 is toggled, the driving force can overcome the static friction force of the toggle member 40 to rotate the toggle member 40, and during the rotation process, the elastic member 10 provides a radial acting force to the toggle member 40 through the abutting member 30, so as to avoid the shaking of the toggle member 40. After the toggle member 40 rotates relative to the bracket 20 by a predetermined angle, that is, after the toggle member 40 stops rotating, the toggle member 40 is positioned by the abutting member 30.

The driving force may be a force directly applied to the toggle member 40 by a user, or may be a force applied to the toggle member 40 when the electric driving member is powered on, and is not particularly limited herein. The preset angle can be realized by the clamping structure of the adjusting device 100, and can also be controlled by the electrical parameters such as the power-on time of the electric driving element, and the angle scale on the bracket 20 can remind the user of how many angles are rotated to realize the preset angle.

The adjusting apparatus 100 according to the embodiment of the present application may be installed in an electronic device, and used for adjusting a function or a parameter related to the function of the electronic device or selecting the function or the parameter in the electronic device. In one example, the adjusting apparatus 100 of the embodiment of the present application may be mounted on a camera, and a user may toggle the toggle member 40 to rotate when using the camera, and the rotation angle of the toggle member 40 may be converted into a parameter adjustment or a parameter selection of a user interface of the camera.

In addition, in the illustrated embodiment, the elastic member 10 includes a spring. In other embodiments, the elastic member may include a spring or other members that provide elastic force through elastic deformation. The number of the elastic members 10 may be one or at least two. It can be understood that when the number of the elastic element 10 is one, two ends of the elastic element 10 abut against the abutting element 30, and the supporting element 21 can be connected to the portion between the two ends of the elastic element 10 to provide support for the elastic element 10.

The bracket 20 may be made of plastic or metal. In the present embodiment, the bracket 20 is injection molded using plastic through an injection molding process. The toggle 40 may be made of plastic or metal. In the present embodiment, the driver 40 is made of metal (e.g., aluminum alloy).

The holding member 30 may be in the shape of a sphere, a square, or other regular or irregular shapes. In the embodiment of the present application, the abutting member 30 is spherical, and the first abutting portion 11 abuts against the toggle member 40 through the spherical abutting member 30, so that the resistance when the toggle member 40 rotates is small.

Referring to fig. 10 to 12, in some embodiments, the number of the elastic elements 10 is at least two, and at least two elastic elements 10 are uniformly spaced along the circumferential direction of the supporting element 21.

Thus, when the at least two elastic members 10 are uniformly arranged along the circumferential direction of the supporting member 21 at intervals, the directions of the abutting forces provided by the two elastic members 10 along the same radial direction of the toggle member 40 are opposite, which is beneficial to improving the stability of the toggle member 40 in a rotating or static state and can effectively reduce the shaking of the toggle member 40.

Specifically, the number of the elastic members 10 may be two, three, four, or four or more, etc. In the illustrated embodiment, the number of the elastic members 10 is two, and the two elastic members 10 are arranged at an angle of 180 degrees apart along the circumferential direction of the support member 21. When the number of the elastic members 10 is three, the three elastic members 10 are arranged at an angle of 120 degrees along the circumferential direction of the support member 21; when the number of the elastic members 10 is four, four elastic members 10 are arranged at an angle of 90 degrees in the circumferential direction of the support member 21. That is, when the number of the elastic members 10 is N (N is a natural number and N >1), the angle between two adjacent elastic members 10 is 360/N. The at least two elastic members 10, which are uniformly spaced, are advantageous to provide the toggle member 40 with a uniformly distributed force in the radial direction of the toggle member 40.

Referring to fig. 10 and 11, in some embodiments, the supporting member 21 is provided with accommodating cavities 211 corresponding to the elastic members 10 one by one, and the elastic members 10 are accommodated in the accommodating cavities 211.

Thus, the elastic element 10 is accommodated in the accommodating cavity 211, and the accommodating cavity 211 can provide a guiding function for the deformation direction of the elastic element 10, that is, the elastic element 10 can be deformed along the radial direction of the toggle element 40, so that the elastic element 10 can correctly provide a pushing force along the radial direction of the toggle element 40.

Specifically, the receiving cavity 211 may be a circular hole, a square hole or a hole with other shapes formed on the supporting member 21. When the number of the elastic members 10 is one, the accommodating cavity 211 may be a through hole, one elastic member 10 is accommodated in the accommodating cavity 211 and can be fixed in the accommodating cavity 211, two ends of the elastic member may serve as two first abutting portions 11, and a portion abutting against the supporting member 21 and located between the two ends of the elastic member 10 may serve as a second abutting portion 12. When the number of the elastic members 10 is at least two, the accommodating cavities 211 corresponding to the number of the elastic members 10 one to one may be blind holes, one end of the elastic member 10 may abut against the bottom of the blind holes, one end abuts against the abutting member 30, and one end of the abutting member 30 serves as the first abutting portion 11. One end of the elastic element 10 abutting against the supporting element 21 can be used as a second abutting portion 12.

Referring to fig. 11 and 12, in some embodiments, there are two elastic members 10, the two elastic members 10 are arranged along a straight line L, and the first abutting portions 11 are respectively located at one end of the elastic member 10 away from the other elastic members 10. Thus, the two elastic members 10 can respectively abut against one abutting portion in opposite directions, that is, the abutting forces generated by the two elastic members 10 are on the same straight line L. Specifically, the straight line L may be disposed in a radial direction of the dial 40.

Referring to fig. 11, in some embodiments, the elastic member 10 further includes second abutting portions 12, two of the second abutting portions 12 abut against the supporting member 21, and the abutting members 30 abut against the corresponding first abutting portions 11 of the elastic member 10. In this way, the supporting element 21 can provide a fulcrum for the elastic element 10, so that the elastic element 10 can provide a holding force for the holding element 30 after being abutted against the holding element 30.

Referring to fig. 11 and 12, in some embodiments, the two elastic members 10 provide the pushing forces F1 and F2 to the toggle member 40 in the same magnitude and opposite directions. Thus, the toggle member 40 receives two abutting forces F1 and F2 with equal magnitude and opposite directions, so that the stability of the toggle member 40 can be improved, and the shaking of the toggle member 40 can be further reduced.

In some embodiments, the holding forces provided by the at least two elastic members 10 to the toggle member 40 are all equal in magnitude. Thus, the toggle member 40 can receive the abutting force with equal magnitude and uniform distribution along the circumferential direction of the support member 21, and the toggle member 40 can smoothly rotate when being toggled on the premise of keeping stability.

In some embodiments, at least two of the elastic members 10 have the same modulus of elasticity, or are different from each other, or are partially the same and partially different. In this manner, the elastic force provided by the elastic member 10 can be adjusted by the modulus of elasticity.

Specifically, the elastic modulus of at least two elastic members 10 are the same, and when the elastic members 10 are disposed on the adjusting device 100, the magnitude of the supporting force provided by each elastic member 10 under the same deformation amount is the same.

The elastic modulus of at least two elastic members 10 are different, and the magnitude of the supporting force provided by each elastic member 10 under the same deformation amount is different, but when the elastic members 10 are disposed on the adjusting device 100, the elastic members 10 uniformly arranged along the circumferential direction of the supporting member 21 may have different deformation amounts, so that the supporting force applied by each elastic member 10 to the toggle member 40 is equal, thereby better maintaining the stability of the toggle member 40.

When the elastic moduli of the at least two elastic members 10 are partially the same and partially different, the deformation amount of the elastic member 10 having the same elastic modulus may be different from the deformation amount of the elastic member 10 having the different elastic modulus, so that the abutting forces provided by the at least two elastic members 10 to the toggle member 40 may be equal as a whole.

Referring to fig. 10 to 12, in some embodiments, the adjusting device 100 includes an adaptor 50 fixed in the toggle member 40, the adaptor 50 is annular, the elastic member 10 and the abutting member 30 are located in a space formed in the adaptor 50, a plurality of positioning grooves 51 are formed in an inner wall of the adaptor 50 along a circumferential direction of the adaptor 50, and the abutting member 30 is respectively engaged with the positioning grooves 51.

Thus, when the toggle member 40 is rotated, the elastic member 10 can engage the holding member 30 in different positioning slots 51, and when the holding member 30 is engaged in the positioning slot 51, resistance is provided for the rotation of the toggle member 40, so as to increase the section sense of the user when the toggle member 40 is rotated, and improve the accuracy of the adjustment device 100 in adjusting functions or parameters.

Specifically, the shifting member 40 is usually made of metal, and in order to avoid excessive wear to the abutting member 30 when the shifting member 40 rotates, an adaptor 50 is added between the shifting member 40 and the abutting member 30, and the material of the adaptor 50 may be plastic. The toggle member 40 drives the adaptor member 50 to rotate, and the adaptor member 50 and the abutting member 30 rub against each other. Further, the adaptor 50 may be made of POM plastic, and the adaptor 50 made of POM plastic has the characteristics of high hardness, high rigidity and high wear resistance, and can withstand frequent friction or collision between the holding member 30 and the abutting member to minimize wear.

The adaptor 50 may be secured within the toggle member 40 by adhesive, interference fit, threaded connection, or other connection means. The adaptor 50 of the embodiment of the application is fixed in the toggle piece 40 in a bonding mode, and the bonding connection mode is simple, environment-friendly and convenient to install.

Referring to fig. 12, in some embodiments, each positioning groove 51 includes a first side 511 and a second side 512 opposite to each other along the circumferential direction of the adaptor 50, and the first side 511 and the second side 512 are inclined toward the inside of the positioning groove 51, so that the abutting member 30 is guided by the first side 511 or the second side 512 to be clamped into the positioning groove 51 during the rotation of the toggle member 40.

Thus, the inclined first side surface 511 and the inclined second side surface 512 can play a role in guiding the abutting member 30 to fall into the positioning groove 51, and can also play a role in slowing down the fall of the abutting member 30 to fall into the positioning groove 51, so as to reduce the collision between the abutting member 30 and the adaptor 50, thereby reducing the abrasion between the abutting member 30 and the adaptor 50, and improving the service life of the adjusting device 100 as a whole.

Referring to fig. 12, in some embodiments, the holding member 30 is spherical, when the holding member 30 is located on the first side 511, the first side 511 is tangent to the holding member 30, and when the holding member 30 is located on the second side 512, the second side 512 is tangent to the holding member 30.

Thus, when the spherical abutting member 30 passes through the first side 511 or the second side 512, the spherical abutting member 30 can receive a smaller resistance, so that the abutting member 30 can more smoothly fall into the positioning groove 51, and the phenomenon of a virtual position caused by the fact that the abutting member 30 does not fall into the positioning groove 51 in the rotating process of the toggle member 40 is avoided.

It is understood that when the holding member 30 contacts the first side 511 or the second side 512, it can be understood that the holding member 30 is located on the first side 511 or the second side 512, and the holding member 30 is tangent to the first side 511 or the second side 512.

Referring to fig. 12, in some embodiments, the positioning grooves 51 are uniformly arranged on the inner wall of the adaptor 50 along the circumferential direction of the adaptor 50.

Thus, the distance between every two adjacent positioning slots 51 is the same, so that when the user rotates the toggle member 40, the distance between the abutting member 30 falling into each slot is the same every time the user rotates one slot, and a uniform section feeling is provided for the user.

Referring to fig. 10 and 11, in some embodiments, the adaptor 50 is provided with a shaft 52, and the shaft 52 is rotatably connected to the bracket 20.

In this manner, the toggle member 40 may be rotatably coupled to the bracket 20 via the adaptor member 50.

Specifically, the adaptor 50 is typically made of a material with high plasticity, such as plastic, and the toggle member 40 is typically made of a material with low plasticity, such as metal. By providing the rotating shaft 52 on the adapter 50, the cost is low and the process is relatively simple. In addition, the adaptor 50 is fixed on the toggle member 40, when the toggle member 40 is rotated, the adaptor 50 rotates simultaneously, and the rotating shaft 52 may also output the rotation angle of the toggle member 40, thereby playing a role in adjusting functions or parameters of the electronic device.

Referring to fig. 10, in some embodiments, the dial 40 is formed with a slip prevention portion 41 on an outer circumferential surface thereof, and the slip prevention portion 41 is used to increase a frictional force when the dial 40 is toggled. Thus, the anti-slip part 41 can facilitate the user to rotate the toggle piece 40 more easily, and the user experience is improved.

Specifically, the anti-slip portion 41 may be a groove formed on the outer peripheral surface of the dial 40, a bump formed on the outer peripheral surface of the dial 40, or a member capable of increasing friction provided on the outer peripheral surface of the dial 40.

Referring to fig. 10 and 11, in some embodiments, the bracket 20 includes an upper bracket 22 and a lower bracket 23 connected to each other, and the toggle member 40 is partially disposed in the receiving space 24 formed by the upper bracket 22 and the lower bracket 23.

In this way, the toggle 40 is partially disposed in the accommodating space 24 formed by the upper bracket 22 and the lower bracket 23, so that the shaking of the toggle 40 can be further reduced by the spatial structure of the upper bracket 22 and the lower bracket 23, and the toggle 40 can be operated by the user at a position outside the accommodating space 24.

In some embodiments, the supporting member 21 may be disposed on the upper bracket 22, and thus, the elastic member 10 may also be disposed on the upper bracket 22. In some embodiments, the supporting member 21 may be disposed on the lower bracket 23, and thus the elastic member 10 may be disposed on the lower bracket 23. In some embodiments, when there are two or more supporting members 21, a part of the number of supporting members 21 is disposed on the upper frame 22, another part of the number of supporting members 21 is disposed on the lower frame 23, a part of the number of elastic members 10 is disposed on the upper frame 22, and another part of the number of elastic members 10 is disposed on the lower frame 23.

As such, the arrangement of the elastic member 10 can be flexibly changed according to the disposed position of the support member 21.

In the embodiment shown in fig. 11, the supporting member 21 is disposed on the upper frame 22, and the elastic member 10 is correspondingly received in the receiving cavity 211 of the upper frame 22.

Referring to fig. 10, in some embodiments, the upper bracket 22 is formed with a first positioning portion 221, the lower bracket 23 is formed with a second positioning portion 231, and the first positioning portion 221 and the second positioning portion 231 are cooperatively connected to fix the relative positions of the upper bracket 22 and the lower bracket 23.

In this way, the first positioning portion 221 and the second positioning portion 231 can fix the relative positions of the upper bracket 22 and the lower bracket 23, which can improve the assembly efficiency of the bracket 20.

Specifically, in the embodiment shown in fig. 10, the first positioning portion 221 includes two positioning holes formed in the upper bracket 22, and the second positioning portion 231 may include two positioning posts formed in the lower bracket 23, and the positioning holes and the positioning posts are in one-to-one fit connection to fix the relative positions of the upper bracket 22 and the lower bracket 23. In other embodiments, the first positioning portion 221 may include two positioning posts formed by the upper frame 22, the second positioning portion 231 may include two positioning posts formed by the lower frame 23, the first positioning portion 221 may include one positioning post and one positioning hole formed by the upper frame 22, and the second positioning portion 231 may include one positioning post and one positioning post formed by the lower frame 23. After the upper bracket 22 and the lower bracket 23 are positioned and installed, the upper bracket 22 and the lower bracket 23 can be fixedly connected by using screws, buckles and the like.

Referring to fig. 9 to 12, in the illustrated embodiment, the number of the elastic members 10 is two, and the elastic members 10 are two identical springs. The number of the abutting pieces 30 is the same as that of the elastic pieces 10, and the abutting pieces 30 are steel balls. The supporting member 21 is disposed on the upper bracket 22, the two elastic members 10 are respectively accommodated in two accommodating cavities 211 formed in the supporting member 21, and the two elastic members 10 are disposed along a straight line L along a radial direction of the toggle member 40. The second abutting portion 12 of the elastic element 10 abuts against the bottom of the corresponding accommodating cavity 211, the first abutting portion 11 abuts against the corresponding abutting element 30, and the abutting force is applied to the abutting element 30 to enable the abutting element 30 to abut against the inner wall of the adaptor 50. Therefore, the two elastic members 10 respectively provide two abutting forces F1 and F2 with equal magnitude and opposite directions for the adaptor 50, so that the adaptor 50 and the toggle member 40 fixedly connected with the adaptor 50 can be stably installed on the adjusting device 100.

When the toggle member 40 is rotated, the adaptor member 50 fixedly connected with the toggle member 40 rotates simultaneously, and the abutting member 30 falls into the positioning groove 51 formed on the inner wall of the adaptor member 50, so as to provide a section sense for the rotation of the toggle member 40. When the supporting member 30 is located on the first side surface 511 or the second side surface 512, the supporting member 30 is tangent to the first side surface 511 or the second side surface 512, so that the supporting member 30 can more smoothly fall into the positioning slot 51, and the phenomenon of false position caused by the supporting member 30 not falling into the positioning slot 51 is avoided.

In some embodiments, referring to fig. 11, the adjusting device 100 includes an angle sensor 60, the angle sensor 60 is connected to the toggle member 40, and the angle sensor 60 is used for sensing a rotation angle of the toggle member 40. In this way, the rotation angle of the toggle member 40 can be converted into an electric signal to be output, and parameters of the electronic device can be adjusted or selected.

In the embodiment shown in fig. 11, the toggle 40 is connected to the angle sensor 60 via the rotating shaft 52. Specifically, referring to fig. 13, the angle sensor 60 includes a housing 601, a circuit board 602, a conductive member 603, an inner ring portion 604 and an outer ring portion 605, wherein one end of the rotating shaft 52 extends into the housing 601, the conductive member 603 is fixedly connected to the rotating shaft 52, the toggle member 40 is connected to the conductive member 603 through the rotating shaft 52, and when the toggle member 40 rotates, the rotating shaft 52 drives the conductive member 603 to rotate. The conductive member 603 includes a first abutting portion 6031 and a second abutting portion 6032.

The inner ring portion 604 and the outer ring portion 605 are provided on the circuit board 602 at an interval, the inner ring portion 604 and the outer ring portion 605 are concentrically provided, the first contact portion 6031 contacts the inner ring portion 604, and the second contact portion 6032 contacts the outer ring portion 605. Preferably, the first abutting portion 6031 and the second abutting portion 6032 have certain elasticity, so that the connection reliability with the corresponding ring portion can be increased.

Referring to fig. 13, the outer ring 605 includes a plurality of conductive blocks 6051 disposed at intervals, and during the rotation of the toggle member 40, the second abutting portion 6032 abuts against one of the conductive blocks 6051 so that the inner ring 604 is electrically connected to the conductive block 6051 abutted by the second abutting portion 6032. So that the angle sensor 60 can output a pulse. By the continuous rotation of the dial member 40, each time the second abutting portion 6032 abuts against one of the conductive blocks 6051, the angle sensor 60 outputs one pulse, the number of pulses may correspond to the adjustment range of the parameter, one pulse may be set to correspond to one adjustment range of the parameter, for example, one pulse may be output so that the value of the parameter is increased by 1 or decreased by 1, or two pulses may be output so that the value of the parameter is increased by 1 or decreased by 1, and the like. For a camera, the parameters may include zoom parameters, ISO parameters, shot scene parameters, and the like.

In some embodiments, the inner ring portion includes a plurality of conductive blocks disposed at intervals, and during the rotation of the toggle member, the first abutting portion abuts one of the conductive blocks so that the outer ring is electrically connected to the conductive block abutted by the first abutting portion. Therefore, the rotation angle of the toggle piece can be converted into an electric signal to be output.

In some embodiments, the inner ring portion and the outer ring portion each include a plurality of conductive blocks disposed at intervals, and during the rotation of the toggle member, the first abutting portion abuts against one of the conductive blocks of the inner ring portion, and the second abutting portion abuts against one of the conductive blocks of the outer ring portion, so that the conductive block abutting against the first abutting portion and the conductive block abutting against the second abutting portion are electrically connected. Therefore, the rotation angle of the toggle piece can be converted into an electric signal to be output.

It should be noted that in other embodiments, the angle sensor may comprise a light sensor including a light emitting element (e.g., a light emitting diode) and a light receiving element (e.g., a photodiode) disposed on a circuit board, with a perforated light blocking element, such as a grating, disposed on the shaft for rotation therewith.

In the electronic device 1000, the elastic member 10 and the abutting member 30 can provide abutting force to the toggle member 40, so that the toggle member 40 can be kept stable in a rotating process or a static state, and the influence of shaking of the toggle member 40 on the normal use of the adjusting device 100 can be avoided, thereby ensuring the adjusting effect of the adjusting device 100.

In some embodiments, the electronic device 1000 includes a camera, the adjusting device 100 is mounted on a body 200 of the camera, and the adjusting device 100 is used for adjusting parameters of the camera or selecting parameters of the camera. Thus, the shooting device with the adjusting device 100 can stably and smoothly adjust the functions and parameters of the shooting device through the adjusting device 100, and user experience is improved.

In addition, the electronic device 1000 may also include other electronic devices 1000 that require parameter adjustment or selection, such as a remote controller.

At present, electronic devices are widely used to implement corresponding functions, for example, the electronic devices may include an image sensor for imaging, a memory for storage, a processor for signal processing, and the like. When the electronic device works, the electronic device usually generates heat, and if the heat is not dissipated in time, the normal work of the electronic device is adversely affected. For example, high temperature may affect the imaging quality of the image sensor, may cause the problem of solder joint detachment between the image sensor and the printed circuit board, and may affect the normal use of the electronic device.

The embodiment of the application provides a heat dissipation structure, which is applied to heat dissipation of an image sensor, such as an image sensor of a shooting device. The heat dissipation structure of the embodiment of the present application can also be applied to heat dissipation of components such as memories, processors, and the like, for example, components such as Double Data Rate SDRAM (DDR SDRAM), Digital Signal Processor (DSP), and the like.

Referring to fig. 15 to 17, a heat dissipation structure 8100 is provided in an embodiment of the present disclosure. The heat dissipation structure 8100 includes a functional component 810, a first heat conduction layer 820, and a heat dissipation plate 830. The functional assembly 810 comprises an electronic device 811 and a circuit board 812, the circuit board 812 comprises a first face 8121 and a second face 8122 which are opposite, the electronic device 811 is arranged on at least one of the first face 8121 and the second face 8122, and the electronic device 811 comprises a heat generating device. A first thermally conductive layer 820 is disposed on the second side 8122, the first thermally conductive layer 820 substantially conforming to the second side 8122. The first heat conductive layer 820 connects the heat sink 830 and the circuit board 812, and the heat sink 830 serves to dissipate heat of the functional component 810 conducted through the first heat conductive layer 820.

In the heat dissipation structure 8100, the heat of the functional component 810 can be transferred to the heat dissipation plate 830 through the first heat conduction layer 820, and the heat dissipation plate 830 dissipates the heat to the outside of the heat dissipation structure 8100, so that the heat of the functional component 810 can be effectively dissipated, and the normal use of the functional component 810 is ensured.

The heat dissipation structure 8100 according to the embodiment of the present application can be applied to heat dissipation of the image sensor 8111, for example, heat dissipation of the image sensor 8111 of a camera or the like. The heat dissipation structure 8100 of the embodiment of the present application may also be applied to heat dissipation of components such as a memory and a processor, for example, components such as a Double Data Rate SDRAM (DDR SDRAM) and a Digital Signal Processor (DSP). In the present embodiment, heat dissipation of the image sensor 8111 of the camera to which the heat dissipation structure 8100 is applied will be described as an example.

The image sensor 8111 is an important component of a camera, is a component for converting an optical signal into an electronic signal, and is widely applied to digital cameras and other shooting devices, because the more pixels of the image sensor 8111, the larger the size of the image sensor 8111, the larger the heat generation amount of the image sensor 8111 in the use process of the camera, and the image sensor 8111 is arranged on the circuit board 812, the different coefficients of thermal expansion and cold contraction of the circuit board 812 and the image sensor 8111 can cause the welding point between the connecting circuit board 812 and the image sensor 8111 to fall off in the expansion and contraction processes, thereby reducing the service life of the image sensor 8111 and further reducing the service life of the camera.

It should be noted that there are three main ways of transferring heat, namely heat conduction, heat radiation and convection. Thermal conduction is the means of heat transfer between objects in contact with each other, such as intermetallic heat conduction. Thermal radiation is the effect of heat transfer between objects by emitting and absorbing infrared rays from each other, e.g. the temperature of the objects rises after receiving solar radiation. Convection is the means of conducting heat through the circulation of a fluid, such as a radiator, to heat the air in a room.

The heat dissipation structure 8100 of the embodiment of the present application mainly utilizes heat conduction and heat radiation for heat dissipation. That is, after the heating device on the functional component 810 generates heat in operation, heat is transferred to the circuit board 812 through heat conduction and heat radiation, the circuit board 812 also transfers heat to the first heat conduction layer 820 through heat conduction and heat radiation, meanwhile, the circuit board 812 also transfers part of heat to the heat dissipation plate 830 through heat radiation, the first heat conduction layer 820 also transfers heat to the heat dissipation plate 830 through heat conduction and heat radiation, finally, the heat dissipation plate 830 transfers the heat of itself to an external space or an external object through heat conduction and heat radiation, a heat transfer channel from the functional component 810 to the heat dissipation plate 830 to the outside of the heat dissipation structure 8100 is formed on the heat dissipation structure 8100, and therefore the function of cooling the functional component 810 is achieved.

Specifically, the first heat conductive layer 820 may include at least one of a heat conductive silicone grease, a heat conductive gel, and a heat conductive pad. The heat-conducting silicone grease has better heat conductivity, good electrical insulation and wider use temperature (-50 ℃ -230 ℃). The heat-conducting gel has long service life, and can be kept for a long time without drying and powdering. The heat conducting gasket has a low life span but is easy to replace. In the embodiment of the present application, the first thermal conductive layer 820 is a thermal grease, which may be coated on the second surface 8122 of the circuit board 812 for conducting heat on the circuit board 812 to the heat dissipation plate 830. Moreover, the first heat conduction layer 820 is formed by utilizing the heat conduction silicone grease, and the first heat conduction layer 820 can be well attached to the second surface 8122 of the circuit board 812 and the electronic devices 811 on the second surface 8122, so that the first heat conduction layer 820 can be in contact with the second surface 8122 and the electronic devices 811 on the second surface 8122 basically without air gaps, and the heat dissipation efficiency is improved. Similarly, the heat dissipation plate can be in contact with the first heat conduction layer 820 without air gaps, and the heat dissipation efficiency is further improved.

In some embodiments, heat sink 830 comprises a metal heat sink. Thus, the heat sink 830 made of metal has good thermal conductivity, and heat on the functional module 810 can be quickly conducted out to the heat sink 830 through the first heat conductive layer 820.

Specifically, the metal heat sink may be made of a metal such as silver (Ag), copper (Cu), gold (Au), aluminum (Al), sodium (Na), iron (Fe), lead (Pb), or an alloy. The heat sink 830 according to the embodiment of the present invention is made of aluminum. The heat sink 830 made of aluminum can quickly dissipate heat from the functional module 810 to the heat sink 830 through the first heat conductive layer 820, and is low in cost and easy to mold.

Of course, in other embodiments, the heat dissipation plate 830 may be made of other alternative materials, and the other alternative materials may include other metal or non-metal materials, which will not be described herein.

In some embodiments, the surface of heat sink 830 is black. Thus, the heat dissipation plate with the black surface can absorb heat quickly.

Specifically, according to kirchhoff's law, on the premise of the same object, a black object absorbs and radiates heat more rapidly than other colors by thermal radiation. It is understood that absorption of heat means absorption of thermal radiation emitted by other objects, and radiant heat is thermal radiation emitted by itself. Therefore, when the surface of the heat dissipation plate 830 is black, the rate at which the heat dissipation plate 830 receives heat radiation from the circuit board 812 and the first heat conductive layer 820 side is high, and the rate at which the heat dissipation plate 830 absorbs heat of the functional component 810 by means of heat radiation can be increased. And the amount of heat radiation is great when heating panel 830 surface is the black, can promote heating panel 830 and dispel the outside ability of heat radiation structure 8100 with the heat that absorbs to heat radiation structure 8100 promotes heat radiation structure 8100's heat-sinking capability.

In some embodiments, the heat dissipation plate 830 has a heat radiation layer on a surface thereof. So, the heat radiation layer can promote the ability that heating panel 830 sent the heat radiation to promote heating panel 830 and dispel the outside ability of heat radiation structure 8100 with the heat that absorbs, thereby promote heat radiation structure 8100's heat-sinking capability.

Specifically, the heat radiation layer may be a heat radiation paint coated on the surface of the heat dissipation plate 830, and the heat radiation paint may improve the heat dissipation effect of the heat dissipation plate 830. The heat radiation paint may be coated on the side of the heat dissipation plate 830 opposite to the first heat conduction layer 820, or may be coated on the entire surface of the heat dissipation plate 830. In the present embodiment, the heat radiation layer is disposed on the side of the heat dissipation plate 830 opposite to the first heat conduction layer 820.

When the heating panel 830 is made by metallic aluminum, the heat radiation layer can also be obtained by anodic oxidation, metallic aluminum can generate one deck alumina membrane on the surface after anodic oxidation, this deck alumina membrane can strengthen the ability that the heating panel 830 sent the heat radiation, and the alumina membrane still has good insulating nature and wearability, plays the guard action to heating panel 830, can promote the life-span on heating panel 830 and heat radiation layer.

It is understood that, in some embodiments, the surface of the heat dissipation plate 830 is black and the surface of the heat dissipation plate 830 is provided with a heat radiation layer.

Referring to fig. 15, in some embodiments, a surface 832 of the heat dissipation plate 830 opposite to the first heat conduction layer 820 is convex and concave. Thus, the surface area of the surface 832 of the heat dissipation plate 830 opposite to the first heat conduction layer 820 can be increased, the total amount of heat radiation emitted by the heat dissipation plate 830 can be increased, the contact area between the heat dissipation plate 830 and air can be increased, the heat transferred to the air by the heat dissipation plate 830 through heat conduction can be increased, and the heat dissipation effect of the heat dissipation plate 830 can be improved as a whole.

As shown in fig. 15, the convex-concave shape of the surface 832 of the heat dissipation plate 830 according to the embodiment of the present invention is a wave shape. In other embodiments, the surface of the heat dissipation plate 830 may be formed with a plurality of grooves, holes, and the like, so as to increase the surface area of the heat dissipation plate 830 and enhance the heat radiation capability of the heat dissipation plate 830.

In some embodiments, circuit board 812 includes a ceramic board. Specifically, the ceramic board and the electronic device 811 have more matched thermal expansion coefficients, and under the same temperature difference, the volume changes of the ceramic board and the electronic device 811 caused by thermal expansion and cold contraction are basically consistent, so that the problem of solder joint falling between the electronic device 811 and the circuit board 812 caused by different thermal expansion coefficients can be effectively reduced. Meanwhile, the ceramic board has good thermal conductivity, that is, the ceramic board has better thermal conductivity, and can effectively transfer heat generated by the electronic device 811 to the first heat-conducting layer 820, so as to transfer the heat to the heat-dissipating plate 830, and finally dissipate the heat to the outside of the heat-dissipating structure 8100.

Referring to fig. 15, in some embodiments, electronic devices 811 are disposed on the first face 8121 and the second face 8122, and the electronic devices 811 disposed on the first face 8121 include at least one of: image sensor 8111, a processor, and a memory.

Thus, the vibration of the bracket assembly 840 is less transmitted to the circuit board 812, and the normal operation of the electronic device 811 on the circuit board 812 is ensured.

Specifically, when the heat dissipation structure 8100 is applied to an electronic device, the electronic device is usually accompanied by vibration during use due to factors such as a use environment, and the vibration may cause an adverse effect on the electronic device 811 on the circuit board 812, for example, a connection between the electronic device 811 and the circuit board 812 may become loose after a long time, and for example, for the electronic device 811 which is particularly sensitive to vibration, for example, the image sensor 8111, a little vibration may cause an imaging blur of the image sensor 8111. Therefore, the circuit board 812 is elastically connected to the mounting posts, and vibration of the bracket assembly 840 is reduced to be transmitted to the circuit board 812 in an elastic manner, so that normal operation of electronic devices on the circuit board 812 is ensured.
