Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 10, an embodiment of the present application discloses a camera module, which includes a camera 100, a supporting base 200, a rolling portion 310, a heat sink 330, and a plurality of heat-conducting rolling balls 320.

The camera 100 is disposed on one side of the supporting base 200, and parameters such as a focal length and pixels of the camera 100 may be determined according to actual requirements, which is not limited herein. The supporting seat 200 may be made of hard materials such as plastic or metal, which can provide a protective effect for the camera 100, and the thickness and specific structure of the supporting seat 200 may be determined according to actual requirements. The rolling part 310 and the heat sink 330 are connected to one side of the camera 100 facing the support base 200, the rolling part 310 and the heat sink 330 can be connected to one side of the camera 100 facing the support base 200 by means of bonding or welding, the rolling part 310 protrudes in a direction away from the camera 100, the surface of the rolling part 310 departing from the camera 100 is of a spherical structure, and parameters such as the diameter of the rolling part 310 can be selected according to actual conditions. The heat-conducting rolling balls 320 may be formed of a heat-conducting material such as metal or graphite, and the number of the heat-conducting rolling balls 320 may be determined according to actual conditions, and the diameters and the materials of the plurality of heat-conducting rolling balls 320 may be the same or different.

The heat sink 330 may be made of a material with relatively good heat conduction effect, such as metal, and the thickness and shape of the heat sink 330 may be determined according to actual requirements, which is not limited herein. The heat sink 330 may be formed integrally with the camera 100, and optionally, the heat sink 330 may be further fixed on the surface of the camera 100 facing the support base 200 by using a thermal conductive adhesive, so as to ensure a high thermal conductive efficiency between the heat sink 330 and the camera 100, and prevent the material selection of the heat sink 330 and the camera 100 from being limited.

Further, the number of the heat dissipation fins 330 may be multiple, and the heat dissipation fins 330 may be all of a sheet structure, and the plurality of heat dissipation fins 330 are parallel to each other and are arranged at intervals, so that the limitation of the gas between two adjacent heat dissipation fins 330 during flowing is relatively smaller, thereby improving the heat dissipation effect of the heat dissipation fins 330.

The plurality of heat-conducting rolling balls 320 are supported on the supporting seat 200, and optionally, the camera 100, the supporting seat 200 and the rolling part 310 are used as boundaries of the plurality of heat-conducting rolling balls 320, so that the plurality of heat-conducting rolling balls 320 are clamped in a space surrounded by the camera 100, the supporting seat 200 and the rolling part 310, and the plurality of heat-conducting rolling balls 320 can be ensured to be always positioned on one side of the supporting seat 200 facing the camera 100. Or, by adding the limit structure and matching each heat-conducting rolling ball 320 with the limit structure, the heat-conducting rolling ball 320 may be limited on the side of the support base 200 facing the camera 100. It should be noted that the aforementioned limiting structure may be the heat dissipation rail 410 (and/or the positioning portion 420) described below.

In order to prevent the existence of the heat sink 330 from limiting the anti-shake action of the camera 100, along the optical axis direction of the camera 100, the rolling portion 310 extends out of one end of the heat sink 330 away from the camera, that is, the rolling portion 310 is closer to the supporting seat 200 than the heat sink 330, which can ensure that the camera 100 can still be supported on the supporting seat 200 through the rolling portion 310, and ensure that the camera 100 can shake relative to the supporting seat 200. The rolling part 310 is supported on at least one heat-conducting rolling ball 320, and the rolling part 310 and the heat-conducting rolling ball 320 are contacted with each other through spherical surfaces, so that relative movement between the rolling part 310 and the heat-conducting rolling ball is ensured, and the camera 100 and the support seat 200 are ensured to move relatively.

Optionally, by distributing the heat-conducting rolling balls 320 over the surface of the supporting seat 200 facing the camera head 100, no matter where the rolling part 310 moves with the camera head 100, it can be ensured that the rolling part 310 can contact with at least one heat-conducting rolling ball 320, so as to provide a supporting and heat-conducting function for the camera head 100. Wherein, the full arrangement means that the plurality of heat-conducting rolling balls 320 are in mutual contact, and the plurality of heat-conducting rolling balls 320 are also limited with the edge of the supporting seat 200, so that the plurality of heat-conducting rolling balls 320 cannot move relative to the supporting seat.

Or, a plurality of heat-conducting rolling balls 320 may be disposed in the central region of the support base 200, and the heat-conducting rolling balls 320 may not move relative to the support base 200 by disposing the limiting structure, and the motion range of the camera 100 is limited, so that the technical scheme may also ensure that at least one heat-conducting rolling ball 320 may contact with the rolling portion 310 all the time during the motion of the camera 100, thereby providing supporting and heat-conducting functions.

As described above, the diameters of the plurality of heat conductive rolling balls 320 may be the same or different, and in the case where the diameters of the plurality of heat conductive rolling balls 320 are the same, the assembling work between the support base 200 and the plurality of heat conductive rolling balls 320 is facilitated. In order to further improve the supporting effect of the heat-conducting rolling balls 320 on the camera 100, the heat-conducting rolling balls 320 may be made different in size, and the diameter of the heat-conducting rolling ball 320 located in the central region of the supporting seat 200 may be made smaller than the diameter of the heat-conducting rolling ball 320 located in the edge region of the supporting seat 200, in which case, the rolling portion 310 may be enabled to contact with more heat-conducting rolling balls 320, thereby improving the heat dissipation efficiency and the motion stability of the camera 100.

Certainly, the camera module further includes, for example, a pan/tilt. Optionally, the driving mechanism is a motor, an electro-deformable member, an electromagnetic driving structure, or the like. The camera 100, the driving mechanism and other components can be connected with the main board of the electronic device through the electric connection module, so that the purposes of information and instruction interaction, energy supply and the like are achieved.

In the camera module disclosed in the present application, camera 100 sets up the one side at supporting seat 200, roll portion 310 and fin 330 are connected in the one side towards supporting seat 200, roll portion 310 is heat conduction structure spare, and roll portion 310 deviates from the surface of camera 100 for the convex spherical structure of the direction of keeping away from camera 100, a plurality of heat conduction rolling balls 320 support on supporting seat 200, along camera 100's optical axis direction, roll portion 310 stretches out outside the one end that deviates from camera 100 to fin 330, and roll portion 310 can support on at least one heat conduction rolling ball 320, camera 100 and supporting seat 200 swing joint, thereby realize the purpose of anti-shake cloud platform. Moreover, as the camera 100 is in contact with the supporting seat 200 through the rolling part 310 and the heat-conducting rolling ball 320, the camera 100 can transfer its heat to the rolling part 310, and then the heat is conducted to the supporting seat 200 through the heat-conducting rolling ball 320, and finally the heat is dissipated out of the camera module through the supporting seat 200; meanwhile, the cooling fin 330 is further arranged on one side of the camera 100 facing the support seat 200, and the cooling fin 330 can also absorb heat of the camera 100, so that the camera 100 and the camera module are prevented from being too high in temperature, and the camera module is guaranteed to have a longer service life.

Optionally, at least one of the support base 200, the rolling portion 310 and the heat conductive rolling balls 320 is a metal structural member, and further, the support base 200, the rolling portion 310 and each of the heat conductive rolling balls 320 is a metal structural member. Under this condition, can guarantee that supporting seat 200 can provide higher protective effect for camera 100, optionally, cloud platform support 500 also is metal structure to further promote the guard action to camera 100, and can guarantee that the structural strength of whole camera module is higher. The rolling portion 310 and the heat conduction rolling ball 320 made of metal materials have high heat conduction efficiency and high structural strength, so that the camera 100 is guaranteed to move relative to the supporting seat 200, the rolling portion 310 and the heat conduction rolling ball 320 can provide good supporting effect for the camera 100, and the motion stability of the camera 200 is improved.

Optionally, the radii of the heat-conducting rolling balls 320 are the same, in this case, on one hand, the spare part work is facilitated to be performed, and on the other hand, in the case that the radii of the plurality of heat-conducting rolling balls 320 are the same, the relative rotation between the rolling part 310 and each heat-conducting rolling ball 320 is also substantially the same, so that no matter which heat-conducting rolling ball 320 the rolling part 310 supports, the motion amplitude of the camera 100 is substantially not changed, which makes the stability and precision of the camera 100 when moving relative to the support base 200 relatively higher, and thus the pan-tilt anti-shake effect can be further improved.

When the radius of each heat-conducting rolling ball 320 is the same, the surface of the support base 200 facing the camera may be a planar structure, in this case, a plurality of heat-conducting rolling balls 320 with the same radius may be tiled on the surface of the support base 200 facing the camera 100, which may ensure that the rolling portion 310 may move relative to the heat-conducting rolling ball 320 in the process of acting with the camera 100, and is supported on at least one heat-conducting rolling ball 320, thereby ensuring that the heat-conducting rolling ball 320 may provide a supporting and heat-transferring effect for the rolling portion 310 and the camera 100.

In order to further improve the motion stability between the camera 100 and the supporting base 200 in the camera module, in the case that the radii of the heat-conducting rolling balls 320 are the same, optionally, the supporting base 200 may be provided with a sinking groove 221, and the groove surface of the sinking groove 221 is a spherical structure, and the plurality of heat-conducting rolling balls 320 are all supported on the sinking groove 221. Under the condition of adopting above-mentioned structure, a plurality of heat conduction rolling balls 320 can form spherical structure towards the surface of camera 100, and then make rolling portion 310 that has spherical structure can contact each other with more heat conduction rolling balls 320, can promote the stability that camera 100 was supported on the one hand, and on the other hand can increase the area of contact between camera 100 and the supporting seat 200, promotes camera 100's radiating efficiency.

Specifically, the size of the sink groove 221 may be determined according to the radius of the rolling part 310 and the radius of the plurality of heat conductive rolling balls 320. For example, in the case where the plurality of heat conductive rolling balls 320 have the same radius, the plurality of heat conductive rolling balls 320 may be directly laid on the sinking groove 221, and the rolling part 310 may be supported on more heat conductive rolling balls 320 by making the radius of the sinking groove 221 larger than the radius of the rolling part 310; also, even if the rolling part 310 moves along with the camera head 100, it is ensured that the rolling part 310 can be supported on the at least one heat conductive rolling ball 320. In addition, in the case where the diameters of the heat conductive rolling balls 320 are different, the heat conductive rolling balls 320 of different sizes supported on the sinking groove 221 may be formed in a spherical surface by designing the size such as the radius of the sinking groove 221 according to the radius of the rolling part 310 and the radius of each of the plurality of heat conductive rolling balls 320, so that the rolling part 310 may be supported on more heat conductive rolling balls 320.

Further, the supporting base 200 includes a base 210 and a supporting portion 220, the supporting portion 220 is convexly disposed on one side of the base 210 facing the camera 100, and the supporting portion 220 is provided with a sinking groove 221. Under the condition that adopts above-mentioned technical scheme, can prevent that the existence of heavy groove 221 from producing adverse effect to supporting seat 200, especially the structural strength of pedestal 210, guarantee that supporting seat 200 can provide reliable safeguard effect for camera 100 and whole camera module. Specifically, the seat body 210 and the supporting portion 220 may be formed in an integral molding manner, so as to ensure that the entire supporting seat 200 has high structural strength.

As described above, the heat conductive rolling balls 320 may be distributed over the support seat 200, or the heat conductive rolling balls 320 may be formed in the support seat 200 in such a manner that the grooves 221 are formed therein, so that the heat conductive rolling balls 320 and the support seat 200 do not undergo relative displacement.

Or, optionally, the camera module disclosed in the embodiment of the present application further includes a heat dissipation rail 410, the heat dissipation rail 410 may be a long strip structure, and the heat dissipation rail 410 is connected to one side of the support base 200 facing the camera 100. Specifically, the heat dissipation rail 410 may be made of a hard material such as metal, and in the case that the support base 200 is also made of a metal material, the heat dissipation rail 410 may be connected to the support base 200 by welding. Optionally, the heat dissipation guide rail 410 may be further fixed to the support base 200 by bonding with a heat conductive adhesive, so that the support base 200 and the heat dissipation guide rail 410 are prevented from being limited in material selection while high heat conduction efficiency is ensured between the support base 200 and the heat dissipation guide rail 410. In addition, the size and specific structure of the heat dissipation rail 410 may be selected according to actual conditions.

Each heat-conducting rolling ball 320 is rotatably disposed on the heat-dissipating guide rail 410, and a part of each heat-conducting rolling ball 320 protrudes from one side of the heat-dissipating guide rail 410 away from the camera 100, and the height of the part of each heat-conducting rolling ball 320 protruding out of the heat-dissipating guide rail 410 is equal, so that the heat-conducting rolling balls 320 can be prevented from moving relative to the support base 200 while the heat-conducting rolling balls 320 are ensured to rotate relative to the rolling part 310, and the stability of the relative movement between the camera 100 and the support base 200 is improved.

In order to implement the above technical solution, optionally, a plurality of positioning grooves are disposed on one side of the heat dissipation rail 410 facing the camera 100, the plurality of heat conduction rolling balls 320 are disposed in the plurality of positioning grooves in a one-to-one correspondence, and each heat conduction rolling ball 320 rolls in one positioning groove. In this case, the positioning groove can limit the relative position between each heat-conducting rolling ball 320 and the heat-dissipating guide rail 410, so as to ensure that the heat-conducting rolling ball 320 does not move relative to the heat-dissipating guide rail 410 during the anti-shaking process, thereby stabilizing the relative movement between the heat-conducting rolling ball 320 and the rolling part 310.

Specifically, the groove surface of the positioning groove may be a spherical surface, and the radius of the positioning groove may be greater than the radius of the heat-conducting rolling ball 320, so that while it is ensured that the heat-conducting rolling ball 320 can be mounted to the positioning groove, the heat-conducting rolling ball 320 can also rotate in the positioning groove relatively easily, the rolling portion 310 can move relative to the heat-conducting rolling ball 320, and then relative movement between the camera 100 and the support base 200 is ensured. As shown in fig. 3, by making the depth of the positioning groove smaller than the diameter of the heat-conducting rolling ball 320, a portion of the heat-conducting rolling ball 320 can extend out of the positioning groove and further contact with the rolling portion 310, providing the functions of supporting the camera 100 and transferring heat of the camera 100 to the supporting base 200.

In addition, under the condition that the radiuses of the plurality of heat-conducting rolling balls 320 are the same, the heights of the parts of the heat-conducting rolling balls 320 protruding out of the heat-radiating guide rail 410 can be ensured to be equal by making the depths and the arrangement positions of the positioning grooves the same. In the case that the plurality of heat conductive rolling balls 320 have different radii, the centers of the plurality of heat conductive rolling balls 320 may be located on different planes, which may also ensure that the heights of the portions of the plurality of heat conductive rolling balls 320 protruding out of the heat dissipation rail 410 are equal.

Alternatively, the height of the portion of the heat conductive rolling ball 320 protruding from the heat dissipation rail 410 toward the camera head 100 side of the heat dissipation rail 410 is smaller than the radius of the heat conductive rolling ball 320. That is, a large portion of the heat conductive roller ball 320 is located inside the heat dissipation rail 410, and a small portion of the heat conductive roller ball 320 is located outside the heat dissipation rail 410. As shown in fig. 3, the height of the portion of the heat-conducting rolling ball 320 protruding from the heat-dissipating rail 410 toward the camera head 100 is h3, the maximum diameter of the portion of the heat-conducting rolling ball 320 protruding from the heat-dissipating rail 410 toward the camera head 100 is d3, and the diameter of the heat-conducting rolling ball 320 is d 4.

Based on the above embodiment, under the condition that the positioning groove is formed in the heat dissipation guide rail 410, the depth of the positioning groove is larger than the radius of the heat-conducting rolling ball 320, and the depth of the positioning groove is smaller than the diameter of the heat-conducting rolling ball 320, so that the height of the portion, protruding from the heat dissipation guide rail 410 to the side of the heat dissipation guide rail 410 facing the camera 100, of the heat-conducting rolling ball 320 is smaller than the radius of the heat-conducting rolling ball 320.

Under the condition that the depth of the positioning groove is larger than the radius of the heat-conducting rolling ball 320 and smaller than the diameter of the heat-conducting rolling ball 320, the heat-radiating guide rail 410 can be of a detachable structure, before the heat-radiating guide rail 410 and the heat-conducting rolling ball 320 are assembled, the heat-radiating guide rail 410 can be detached, so that at least two parts of the structure forming the positioning groove are separated, after the heat-conducting rolling ball 320 is installed, at least two parts of the heat-radiating guide rail 410 are assembled into a whole, and the heat-conducting rolling ball 320 and the heat-radiating guide rail 410 can form a reliable connection relation. Moreover, with the above structure, in the extending direction of the heat dissipation guide rail 410, the relative position between the heat-conducting rolling balls 320 and the heat dissipation guide rail 410 is not changed basically, each heat-conducting rolling ball 320 can be matched with one positioning groove, and the heat-conducting rolling ball 320 can roll in the positioning groove matched with the heat-conducting rolling ball.

In this embodiment, the diameters of the plurality of heat-conducting rolling balls 320 may be the same, which may reduce the design difficulty of the heat-dissipating guide rail 410 and improve the stability of the movement between the camera 100 and the support base 200. Further, in order to enable the rolling part 310 to contact with more heat conductive rolling balls 320, alternatively, the surface of the heat dissipation rail 410 facing the camera head 100 may be provided in a spherical structure, in which case the surfaces of the plurality of heat conductive rolling balls 320 facing the camera head 100 can be formed in a structure similar to a spherical structure, thereby enabling the rolling part 310 to contact with more heat conductive rolling balls 320.

Based on the above embodiment, under the condition that the surface of the heat dissipation guide rail 410 facing the camera 100 is of the spherical structure, because the heat dissipation guide rail 410 is located between the support base 200 and the camera 100, the heat of the heat dissipation guide rail 410 also needs to be transferred to the support base 200 to be able to dissipate heat to the outside of the camera module, therefore, optionally, the heat dissipation guide rail 410 is entirely of the arc-shaped spherical structure, in this case, the surface of the heat conduction rolling ball 320 facing the support base 200 is also of the spherical structure, so as to reduce the heat absorbed by the heat dissipation guide rail 410 by reducing the overall size of the heat dissipation guide rail 410, and the heat of the camera 100 is transferred to the support base 200 through the heat dissipation guide rail 410 as much as possible, and is finally dissipated from the support base 200 to the outside of the camera module.

Under the condition that the whole radiating guide rail 410 is of an arc-shaped spherical structure, in order to further increase the contact area between the radiating guide rail 410 and the supporting seat 200, the supporting seat 200 can be provided with the sinking groove, under the condition that the sinking groove is formed in the supporting seat 200, the size of the radiating guide rail 410 is matched with the size of the sinking groove, the radiating guide rail 410 is installed in the sinking groove, the contact area between the radiating guide rail 410 and the supporting seat 200 is increased, and the stability of the radiating guide rail 410 can be further improved.

Alternatively, the diameters of the plurality of heat-conducting rolling balls 320 may be different, in this case, the heat-dissipating guide 410 may have a flat plate-like structure, and the heat-conducting rolling balls 320 having relatively small diameters may be disposed in the central region of the heat-dissipating guide 410, and the heat-conducting rolling balls 320 having relatively large diameters may be disposed in the edge region of the heat-dissipating guide 410, and the centers of the plurality of heat-conducting rolling balls 320 may be located on different planes, respectively, so that the surface of each heat-conducting rolling ball 320 facing the camera head 100 may still be ensured to be formed into a structure similar to a spherical surface, and the rolling part 310 may be supported on more heat-conducting rolling balls 320.

In the case where the heat dissipation rails 410 are long-strip-shaped structural members, the number of the heat dissipation rails 410 may be plural, and the plural heat dissipation rails 410 may be arranged in a crossing manner, and each of the heat dissipation rails 410 may be provided with the plural heat conductive rolling balls 320. With the above technical solution, the distribution range and the distribution direction of the heat-conducting rolling balls 320 can be enlarged, thereby further improving the stability of the fit between the rolling part 310 and the heat-conducting rolling balls 320, which operate with the camera 100.

Specifically, the number of the heat dissipation guide rails 410 may be two, three, or more, and when the number of the heat dissipation guide rails 410 is two, an included angle between the two heat dissipation guide rails 410 may be a right angle or an acute angle, optionally, the two heat dissipation guide rails 410 are formed in an integrally formed manner, so that the connection reliability between the heat dissipation guide rails 410 is relatively high, and adverse effects on the connection reliability between the heat dissipation guide rails 410 due to the existence of connection marks such as welding seams, welding spots, or glue spots between the heat dissipation guide rails 410 may be prevented in the connection process between the heat dissipation guide rails 410 and the support base 200. In the case where the number of the heat dissipation rails 410 is three or more, the relative position between the plurality of heat dissipation rails 410 may be determined according to actual circumstances.

As described above, in the case where the diameters of the heat-conducting rolling balls 320 are the same, in order to increase the number of the heat-conducting rolling balls 320 which are in contact with the rolling portion 310, the surface of the heat-radiating guide 410 facing the camera 100 may be formed in a spherical structure, and in the case where the number of the heat-radiating guide 410 is plural, the surfaces of the plurality of heat-radiating guide 410 facing the camera 100 may be formed in a spherical structure, so that the operational stability between the camera 100 and the support base 200 can be further improved by the common action of the plurality of heat-radiating guide 410.

In another embodiment of the present application, the heat dissipation rail 410 may also be an annular structural member, the plurality of heat conduction rolling balls 320 are distributed along the circumferential direction of the heat dissipation rail 410, in the extending direction of the heat dissipation rail 410, each heat conduction rolling ball 320 is rotatably disposed on the heat dissipation rail 410, a portion of each heat conduction rolling ball 320 protrudes from one side of the heat dissipation rail 410 facing the camera 100, and the heights of the portions of the heat conduction rolling balls protruding from the heat dissipation rail 410 are equal. Under the condition of adopting above-mentioned structure, no matter what kind of orientation relative supporting seat 200 of camera 100 edge rocks, heat dissipation guide rail 410 and heat conduction rolling ball 320 also all can provide stable supporting role for camera 100, have higher stability when guaranteeing that camera 100 carries out the anti-shake action.

As described above, the positioning groove may be formed in the heat dissipation guide rail 410, and the size such as the radius of the positioning groove may be limited according to the size such as the radius of the heat conduction rolling balls 320, so as to ensure that the plurality of heat conduction rolling balls 320 can protrude from one side of the heat dissipation guide rail 410 facing the camera 100, and the heights of the portions of the heat conduction rolling balls 320 protruding from the heat dissipation guide rail 410 are equal, so that the heat conduction rolling balls 320 can provide a substantially uniform support effect for the rolling portion 310, and the camera 100 can have high operation stability.

More specifically, the radii of the plurality of heat-conducting rolling balls 320 distributed along the extending direction of the annular heat-dissipating guide rail 410 may be made equal, and the centers of the plurality of heat-conducting rolling balls 320 may be located in the same plane, which may relatively easily implement the above technical solution, reduce the difficulty in designing the heat-dissipating guide rail 410, and reduce the difficulty in assembling the heat-conducting rolling balls 320 and the heat-dissipating guide rail 410. Of course, when the diameters of the plurality of heat-conducting rolling balls 320 distributed along the extending direction of the annular heat-dissipating guide rail 410 are not equal, by respectively locating the centers of the plurality of heat-conducting rolling balls 320 on different planes, it is also possible to ensure that a part of each heat-conducting rolling ball 320 protrudes from the side of the heat-dissipating guide rail facing the camera, and the heights of the parts of each heat-conducting rolling ball 320 with different diameters protruding out of the heat-dissipating guide rail 410 are equal.

Further, the number of the heat dissipation guide rails 410 with the annular structure may also be multiple, as shown in fig. 8, the multiple annular heat dissipation guide rails 410 include a first heat dissipation guide rail 411 and a second heat dissipation guide rail 412, a radius of the first heat dissipation guide rail 411 is smaller than a radius of the second heat dissipation guide rail 412, the second heat dissipation guide rail 412 is disposed around the first heat dissipation guide rail 411, and a center of the second heat dissipation guide rail 412, a center of the first heat dissipation guide rail 411, and a center of a surface of the camera 100 facing the support base 200 are located on the same straight line.

Specifically, the radius of the heat-conductive rolling balls 320 mounted on the first heat-dissipating guide 411 may be equal to the radius of the heat-conductive rolling balls 320 mounted on the second heat-dissipating guide 412, and the centers of the heat-conductive rolling balls 320 are located in the same plane, so that the rolling portion 310 acting with the camera head 100 can contact with more heat-conductive rolling balls 320 by expanding the distribution range of the heat-conductive rolling balls 320, thereby improving heat transfer efficiency.

Further, in the case that the radius of the heat-conducting rolling ball 320 on the first heat-dissipating guide 411 is equal to the radius of the heat-conducting rolling ball 320 on the second heat-dissipating guide 412, the heat-conducting rolling ball 320 on the second heat-dissipating guide 412 can be closer to the camera head 100 by changing the relative position between the first heat-dissipating guide 411 and the second heat-dissipating guide 412, so that the plurality of heat-conducting rolling balls 320 on the second heat-dissipating guide 412 and the plurality of heat-conducting rolling balls 320 on the first heat-dissipating guide 411 form a structure similar to a spherical surface, the rolling part 310 can simultaneously contact with the heat-conducting rolling balls 320 on the first heat-dissipating guide 411 and the second heat-dissipating guide 412, and the support and heat transfer function provided by the heat-conducting rolling ball 320 on the rolling part 310 are improved.

Alternatively, in order to increase the number of heat-conducting rolling balls 320 in contact with the rolling portion 310, in the case where the first and second heat-dissipating

guide rails

411 and 412 are equal in size in the optical axis direction of the camera head 100, the radius of the heat-conducting rolling ball 320 mounted on the first heat-dissipating guide rail 411 may be made smaller than the radius of the heat-conducting rolling ball 320 mounted on the second heat-dissipating guide rail 412, which may also ensure that the plurality of heat-conducting rolling balls 320 may form a spherical structure.

Still alternatively, under the condition that the sizes of the first heat dissipation guide rail 411 and the second heat dissipation guide rail 412 in the optical axis direction of the camera 100 are equal, a sinking groove with a spherical structure may be formed on the supporting base 200, and the first heat dissipation guide rail 411 and the second heat dissipation guide rail 412 are respectively installed at positions with different depths in the sinking groove, in this case, the plurality of heat conduction rolling balls 320 with equal radii are respectively installed on the first heat dissipation guide rail 411 and the second heat dissipation guide rail 412, and the plurality of heat conduction rolling balls 320 may also form a spherical structure, so as to provide better supporting and heat transfer effects for the rolling portion 310.

As described above, in order to limit the relative displacement between the heat conductive rolling balls 320 and the support seat 200, the relative position between the heat conductive rolling balls 320 and the support base 200 may be restricted by means of the detents, in another embodiment of the present application, the camera module may further include a positioning part 420, the positioning part 420 is located between the rolling part 310 and the supporting seat 200, the positioning portion 420 is fixedly connected to the supporting base 200, the positioning portion 420 has a plurality of through holes, the plurality of heat-conducting rolling balls 320 are correspondingly engaged with the plurality of through holes one by one, and each of the heat-conducting rolling balls 320 extends from the through hole to a side of the positioning part 420 facing the camera 200, this also ensures that the heat conductive rolling balls 320 are not substantially displaced relative to the support base 200, thereby, each of the heat-conducting rolling balls 320 can provide a stable rotation action, so that during the movement of the camera 100 relative to the support base 200, ensuring that the camera head 100 can still contact with the supporting seat 200 through the heat-conducting rolling balls 320.

Specifically, the positioning portion 420 may have a sheet structure, and the radius of the through holes may be determined according to the radius of each of the heat-conductive rolling balls 320, and the radius of each of the through holes may be smaller than the radius of the heat-conductive rolling ball 320 corresponding to the through hole, so as to ensure that the heat-conductive rolling ball 320 does not fall off from the through hole. The positioning portion 420 and the supporting base 200 may be fixed to each other by welding or gluing, and the plurality of heat-conducting rolling balls 320 are sandwiched between the positioning portion 420 and the supporting base 200.

More specifically, when the shape of the positioning portion 420 is adapted to the shape of the surface of the support base 200 facing the camera 100, and the heat-conducting rolling balls 320 are supported on the support base 200, the distance between the position of each through hole in the positioning portion 420 and the support base 200 is greater than the radius of the heat-conducting rolling ball 320 corresponding to the through hole and smaller than the diameter of the heat-conducting rolling ball 320 corresponding to the through hole, and meanwhile, the distance also needs to correspond to the radius of the through hole, in detail, the sum of the distance and the height of the portion of the heat-conducting rolling ball 320 extending out of the positioning portion 420 can be greater than the diameter of the heat-conducting rolling ball 320 corresponding to the position, so as to ensure that the heat-conducting rolling ball 320 installed at the through hole can rotate at the through hole and cannot be separated from the through hole.
