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 11, an embodiment of the present application discloses a camera module, which includes a camera 100, a supporting base 200, and a plurality of heat-conducting rolling balls 300, and the camera module can be applied to an electronic device.

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 heat-conducting rolling balls 300 may be formed of a heat-conducting material such as metal or graphite, and the number of the heat-conducting rolling balls 300 may be determined according to actual conditions, and the radii and materials of the plurality of heat-conducting rolling balls 300 may be the same or different.

The plurality of heat-conducting rolling balls 300 are disposed on one side of the camera 100 facing the support base 200, and optionally, the camera 100 and the support base 200 serve as boundaries of the plurality of heat-conducting rolling balls 300, so that the plurality of heat-conducting rolling balls 300 can be clamped in a space enclosed by the camera 100 and the support base 200, thereby ensuring that the plurality of heat-conducting rolling balls 300 can be always located on one side of the camera 100 facing the support base 200. Alternatively, the heat-conducting rolling balls 300 may be limited on the side of the camera 100 facing the support base 200 by adding a limit structure and matching the heat-conducting rolling balls 300 with the limit structure. It should be noted that the aforementioned limiting structure may be the heat dissipation rail 410 (and/or the positioning portion 420) described below.

A part of the surface of a plurality of heat conduction rolling balls 300 forms the holding surface, and the holding surface is spherical structure spare, that is to say, at least one point on the surface of a plurality of heat conduction rolling balls 300 all is located spherical structure's holding surface to make the overall structure that a plurality of heat conduction rolling balls 300 formed can provide supporting role for camera 100 as a spherical structure spare, and guarantee that camera 100 can follow arbitrary orientation and move about supporting seat 200, provide the effect that the cloud platform is anti-trembled.

Under the condition that the sizes of the plurality of heat-conducting rolling balls 300 are different, spherical grooves can be formed on the supporting seat 200, the heat-conducting rolling balls 300 with larger radius are arranged in the central area of the camera 100, and the heat-conducting rolling balls 300 with smaller radius are arranged in the edge area of the camera 100, so that the heat-conducting rolling balls 300 can be stably clamped between the camera 100 and the supporting seat 200.

Based on the above situation, a plurality of pits may be formed on the surface of the camera 100 facing the support base 200, and the plurality of heat-conducting rolling balls 300 are all correspondingly mounted in the plurality of pits, so that even when the camera 100 moves relative to the support base 200 for pan-tilt anti-shake, the relative position between each heat-conducting rolling ball 300 and the camera 100 may be kept unchanged.

Alternatively, as described above, the relative position between each heat-conducting rolling ball 300 and the camera head 100 may be kept unchanged by adding a limiting structure. Of course, in the case of any of the above technical solutions, the sizes of the heat-conducting rolling ball 300 and other auxiliary structures are designed to ensure that the heat-conducting rolling ball 300 can rotate relative to the camera 100.

In addition, through designing the radius and the arrangement mode of each heat-conducting rolling ball 300 and the parameters such as the distance between the camera 100 and the support seat 200, at least one heat-conducting rolling ball 300 in the camera module after the assembly can be supported on the support seat 200, and the camera 100 is movably connected with the support seat 200.

For example, in the case where the plurality of heat conductive rolling balls 300 have different radii, a diameter of one heat conductive rolling ball 300 of the plurality of heat conductive rolling balls 300 may be equal to an interval between the camera 100 and the support base 200, the heat conductive rolling ball 300 may be mounted at a central region of the camera 100, the heat conductive rolling ball 300 may be always supported on the support base 200, and the remaining heat conductive rolling balls 300 having a smaller diameter may be mounted around the heat conductive rolling ball 300 having a larger diameter. Under the condition of adopting above-mentioned technical scheme, both can guarantee that at least one heat conduction rolling ball 300 can support on supporting seat 200 all the time to carry out the heat transfer, can also prevent that the setting of a plurality of heat conduction rolling balls 300 from producing adverse effect to the anti-shake action of camera 100.

Or, in the case that the plurality of heat-conducting rolling balls 300 have different radiuses, as described above, a spherical recess may be formed in the support base 200, and by supporting the plurality of heat-conducting rolling balls 300 having different radiuses on the spherical recess, it may be ensured that at least one heat-conducting rolling ball 300 may be always supported on the support base 200 for heat transfer, and by moving the plurality of heat-conducting rolling balls 300 in the spherical recess, it may be possible to prevent the setting of the plurality of heat-conducting rolling balls 300 from adversely affecting the anti-shake operation of the camera 100. In addition, in the technical solution disclosed in this embodiment, more heat-conducting rolling balls 300 may be in contact with the supporting seat 200, which may increase the contact area between the camera 100 and the supporting seat 200, thereby increasing the heat transfer efficiency between the camera 100 and the supporting seat 200 to a certain extent.

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, and a plurality of heat conduction rolling balls 300 set up in one side of camera 100 towards supporting seat 200, and a part on the surface of a plurality of heat conduction rolling balls 300 forms the holding surface, and the holding surface is the spherical structure spare for at least one heat conduction rolling ball 300 can support on supporting seat 200, and camera 100 and supporting seat 200 swing joint, thereby realize the purpose of cloud platform anti-shake. And, because camera 100 is formed with the relation of mutual contact through heat conduction rolling ball 300 and supporting seat 200 to make the heat on the camera 100 can conduct to supporting seat 200 through heat conduction rolling ball 300, and distribute outside the camera module through supporting seat 200, prevent that the temperature of camera 100 and camera module is too high, guarantee that camera module has higher life.

Optionally, at least one of the support base 200 and the heat conductive rolling balls 300 is a metal structural member, and further, the support base 200 and each of the heat conductive rolling balls 300 are metal structural members. 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 heat conduction rolling ball 300 made of metal materials has high heat conduction efficiency and high structural strength, ensures that the camera 100 moves relative to the supporting seat 200, and the heat conduction rolling ball 300 can provide good supporting effect for the camera 100 and improve the action stability of the camera 200.

Optionally, the radii of the heat-conducting rolling balls 300 are the same, in this case, on one hand, the spare part work is facilitated, and on the other hand, under the condition that the radii of the heat-conducting rolling balls 300 are the same, the rotation conditions of the heat-conducting rolling balls 300 are basically the same, so that no matter which heat-conducting rolling ball 300 is supported on the supporting seat 200, the action amplitude of the camera 100 is basically not changed, the stability and the precision of the camera 100 in the action relative to the supporting seat 200 are relatively high, and the anti-shake effect of the pan-tilt head can be further improved.

Specifically, under the condition of the radius of the plurality of heat-conducting rolling balls 300, the assembly work between the plurality of heat-conducting rolling balls 300 and the camera 100 can be assisted by other structures, and the camera 100 can be guaranteed to shake relative to the supporting seat 200, so that the anti-shaking function of the holder is generated. Specifically, a spherical structure may be provided on a side surface of the camera head 100 facing the support base 200, and a plurality of heat-conductive rolling balls 300 are mounted on a surface of the spherical structure facing away from the camera head 100, which enables the camera head 100 to rock at a center of the surface facing the support base 200. Alternatively, a plurality of heat-conducting rolling balls 300 may be mounted on the surface of the camera head 100 through the above-mentioned limiting structure, and the centers of the plurality of heat-conducting rolling balls 300 are located on the same spherical surface.

In order to further improve the motion stability between the camera 100 and the supporting base 200 in the camera module, optionally, the supporting base 200 may be provided with a sunken groove 221, a groove surface of the sunken groove 221 is of a spherical structure, and the plurality of heat-conducting rolling balls 300 are supported on the sunken groove 221 at intervals. With the above structure, at least one of the plurality of heat-conductive rolling balls 300 may be supported in the sinking groove 221, and since the groove surface of the sinking groove 221 has a spherical structure, a more stable supporting function may be provided for the heat-conductive rolling ball 300 and the camera 100. Moreover, by adopting the above technical solution, the number of the heat-conducting rolling balls 300 supported on the support base 200 at the same time can be increased, thereby improving the motion stability of the camera 100. It should be noted that the sink 221 may be a spherical groove as mentioned above.

In addition, since the sinking groove 221 has a spherical structure, even when the spherical structure for mounting the heat-conducting rolling ball 300 is provided on the surface of the camera 100 facing the support base 200, it is possible to ensure that the operation of the camera 100 is not affected by the provision of the spherical structure by inserting a part of the spherical structure into the sinking groove 221.

Specifically, the radius of the sinking groove 221 may be made larger than that of the spherical structure, which ensures that the camera head 100 with the spherical structure mounted thereon can rock in the sinking groove 221 by means of the heat-conducting rolling ball 300. Alternatively, when the plurality of heat conductive rolling balls 300 have different radii, the plurality of heat conductive rolling balls 300 may be directly interposed between the camera head 100 and the sink 221.

Further, the supporting base 200 includes a base body 210 and a supporting portion 220, the supporting portion 220 is convexly disposed on one side of the base body 210 facing the camera 100, and the base body 210 is provided with a sinking groove 221. Under the condition of adopting 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.

In order to make the relative position relationship between each heat-conducting rolling ball 300 and the camera 100 easier to control, optionally, the present application may further include a heat-dissipating guide rail 410, the heat-dissipating guide rail 410 may be a long arc-shaped structure, two ends of the heat-dissipating guide rail 410 are both connected to one side of the camera 100 facing the support base 200, and a portion of the heat-dissipating guide rail 410 located between the two ends protrudes in a direction away from the camera 100.

Specifically, the heat dissipation guide rail 410 may be made of a hard material such as metal, and under the condition that the surface of the camera 100 facing the support base 200 is made of a metal material, two opposite ends of the heat dissipation guide rail 410 may be connected with the camera 100 in a welding manner. Optionally, the opposite ends of the heat dissipation guide rail 410 may also be bonded and fixed to the camera 100 through a heat conductive adhesive, so that the camera 100 and the heat dissipation guide rail 410 are ensured to have high heat conduction efficiency, and the materials selected by the camera 100 and the heat dissipation guide rail 410 are also prevented from being limited. In addition, the distance between the two opposite ends of the heat dissipation guide rail 410 and the protruding dimension of the heat dissipation guide rail 410 away from the camera 100 can be selected according to actual conditions.

In the extending direction of the heat dissipation guide rail 410, each heat conduction rolling ball 300 is rotatably disposed on the heat dissipation guide rail 410, and a part of each heat conduction rolling ball 300 protrudes from one side of the heat dissipation guide rail 410 away from the camera 100, and the height of the part of each heat conduction rolling ball 300 protruding from the heat dissipation guide rail 410 is equal, so that when the heat conduction rolling ball 300 can rotate relative to the camera 100, the heat conduction rolling ball 300 can be prevented from moving relative to the camera 100, and the stability of the relative motion between the camera 100 and the support base 200 is further improved. The camera module disclosed in the embodiment of the present application can also reduce the difficulty in assembling the plurality of heat-conducting rolling balls 300 with the camera 100 under the condition that the camera module includes the heat-dissipating guide rail 410.

In order to implement the above technical solution, optionally, one side of the heat dissipation rail 410 facing the support base 200 is provided with a plurality of positioning grooves, the plurality of heat conduction rolling balls 300 are arranged in the plurality of positioning grooves in a one-to-one correspondence, and each heat conduction rolling ball 300 rolls in one positioning groove. Under the circumstances, the relative position between the heat-conducting rolling ball 300 and the heat-dissipating guide rail 410 can be limited by means of the positioning groove, so that the heat-conducting rolling ball 300 cannot move relative to the heat-dissipating guide rail 410 in the anti-shaking process, and the relative movement between the heat-conducting rolling ball 300 and the support seat 200 is stable.

Specifically, the groove surface of the positioning groove may be a spherical surface, and the radius of the positioning groove may be slightly larger than the radius of the heat-conducting rolling ball 300, so that while it is ensured that the heat-conducting rolling ball 300 can be mounted to the positioning groove, the heat-conducting rolling ball 300 can also be rotated in the positioning groove relatively easily, thereby ensuring that the camera 100 can move relative to the support base 200. As shown in fig. 3, by making the depth of the positioning groove smaller than the diameter of the corresponding heat-conducting rolling ball 300, a portion of each heat-conducting rolling ball 300 can extend out of the positioning groove, and then contact with the supporting seat 200, thereby providing the functions of supporting the camera 100 and transferring the heat of the camera 100 to the supporting seat 200. In addition, when the diameters of the heat-conducting rolling balls 300 are different, the depths of the heat-conducting rolling balls 300 corresponding to the diameters of the heat-conducting rolling balls 300 may be determined according to the diameters of the heat-conducting rolling balls 300, and the centers of the heat-conducting rolling balls 300 may be located on different planes, respectively, so that the heights of the portions of the heat-conducting rolling balls 300 protruding out of the heat-dissipating guide 410 may be ensured to be equal.

Optionally, the height of the portion of the heat-conducting rolling ball 300 protruding from the heat-dissipating guide 410 on the side of the heat-dissipating guide 410 away from the camera head 100 is smaller than the radius of the heat-conducting rolling ball 300. That is, a large portion of the heat conductive roller ball 300 is positioned inside the heat dissipation rail 410, and a small portion of the heat conductive roller ball 300 is positioned outside the heat dissipation rail 410. As shown in fig. 3, the height of the portion of the heat-conducting rolling ball 300 protruding from the heat-dissipating guide rail 410 on the side of the heat-dissipating guide rail 410 away from the camera 100 is h3, the maximum diameter of the portion of the heat-conducting rolling ball 300 protruding from the heat-dissipating guide rail 410 on the side of the heat-dissipating guide rail 410 away from the camera 100 is d3, and the diameter of the heat-conducting rolling ball 300 is d 4.

Based on the above embodiment, under the condition that the positioning groove is provided on the heat dissipation guide rail 410, the depth of the positioning groove is larger than the radius of the heat conduction rolling ball 300, and the depth of the positioning groove is smaller than the diameter of the heat conduction rolling ball 300, so that it can be ensured that the height of the part of the heat conduction rolling ball 300 protruding from the heat dissipation guide rail 410 to the side of the heat dissipation guide rail 410 departing from the camera 100 is smaller than the radius of the heat conduction rolling ball 300.

Based on the above embodiment, the heat dissipation guide rail 410 may be a detachable structure, and before the heat dissipation guide rail 410 is assembled with the heat conductive rolling ball 300, the heat dissipation guide rail 410 may be disassembled, so that at least two parts of the structure forming the positioning groove are separated, and after the heat conductive rolling ball 300 is installed, at least two parts of the heat dissipation guide rail 410 are assembled into a whole, so that the heat conductive rolling ball 300 and the heat dissipation guide rail 410 form a reliable connection relationship. Moreover, when the above structure is adopted, in the extending direction of the heat dissipation guide rail 410, the relative position between the heat conduction rolling balls 300 and the heat dissipation guide rail 410 is not changed basically, each heat conduction rolling ball 300 can be matched with one positioning groove, and the heat conduction rolling ball 300 can roll in the positioning groove matched with the heat conduction rolling ball. In this embodiment, the radii of the plurality of heat-conducting rolling balls 300 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.

Of course, when the heat dissipation guide 410 with the above structure is adopted, the radii of the plurality of heat-conducting rolling balls 300 may also be different, as described above, the heat-conducting rolling ball 300 with a relatively large radius may be disposed in the central region of the camera head 100, and the heat-conducting rolling ball 300 with a relatively small radius may be disposed in the edge region of the camera head 100, and by respectively positioning the centers of the plurality of heat-conducting rolling balls 300 on different planes, it may still be ensured that a portion of each heat-conducting rolling ball 300 may protrude out of the heat dissipation guide 410, and the height of the portion of each heat-conducting rolling ball 300 protruding out of the heat dissipation guide 410 is equal, so that the portion of at least one heat-conducting rolling ball 300 outside the heat dissipation guide 410 is supported on the support base 200.

In the case where the heat dissipation rails 410 are long arc-shaped structures, 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 300. In this case, the plurality of heat dissipation guide rails 410 may form an approximately spherical structure, so that the camera 100 may be stably supported on the support base 200 through the heat dissipation guide rails 410 and the heat conductive rolling balls 300 in a shaking process in different directions, thereby making a fitting relationship between the camera 100 and the support base 200 more stable.

Specifically, the number of the heat dissipation guide rails 410 may be two, three, or more, and under the condition that 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 may be formed in an integrally formed manner, so that a connection trace does not exist at a connection position between the two heat dissipation guide rails 410 and the support base 200, and thus in a process that the heat dissipation guide rails 410 and the support base 200 are mutually matched, the heat dissipation guide rails 410 and the support base 200 can be prevented from being limited in relative movement due to the existence of the connection trace such as a welding seam, a welding spot, or a glue spot. 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.

Optionally, the heat dissipation guide rail 410 may also be an annular structural member, the plurality of heat conduction rolling balls 300 are distributed along the circumferential direction of the heat dissipation guide rail 410, in the extending direction of the heat dissipation guide rail 410, each heat conduction rolling ball 300 is rotatably disposed on the heat dissipation guide rail 410, a part of each heat conduction rolling ball 300 protrudes from one side of the heat dissipation guide rail 410 away from the camera 100, and the heights of the parts of each heat conduction rolling ball 300 protruding from the heat dissipation guide 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 300 also all can provide stable supporting role for camera 100, have higher stability when guaranteeing that camera 100 carries out the anti-shake action. Similarly, the radii of the plurality of thermally conductive rolling balls 300 may be the same or different.

In the above embodiment, in order to ensure that the camera 100 can rotate relative to the support base 200, while the camera 100 can still contact the support base 200 through the heat dissipation guide 410 and the heat conduction rolling balls 300, optionally, the support base 200 may be provided with the sinking groove 221, and the groove surface of the sinking groove 221 is in a spherical structure, and by matching the heat dissipation guide 410 provided with the plurality of heat conduction rolling balls 300 with the sinking groove 221, even if the radii of the plurality of heat conduction rolling balls 300 are the same, in the process of the camera 100 moving relative to the support base 200, the plurality of heat conduction rolling balls 300 can be ensured to move relative to the support base 200, and at least one of the plurality of heat conduction rolling balls 300 can be supported in the sinking groove 221, so as to provide a heat conduction path for heat exchange between the camera 100 and the support base 200.

Alternatively, another heat-conductive rolling ball 300 may be further disposed inside the heat-dissipating guide 410, and the heat-conductive rolling ball 300 may be installed in a central region of a surface of the camera head 100 facing the support base 200, and the heat-conductive rolling ball 300 may be further away from the camera head 100 with respect to the heat-conductive rolling ball 300 installed on the heat-dissipating guide 410. When the technical scheme is adopted, in the process that the camera 100 shakes relative to the supporting seat 200, the camera 100 can be always in contact with the supporting seat 200 through the heat-conducting rolling ball 300 so as to serve as a connecting structure between the camera 100 and the supporting seat 200. In addition, in the process that the camera 100 moves relative to the support base 200, a certain part of the structure of the camera 100 moves close to the support base 200, and accordingly, at least one heat-conducting rolling ball 300, which corresponds to a position where the camera 100 is close to the support base 200, of the plurality of heat-conducting rolling balls 300 mounted on the heat-radiating guide 410 can contact with the support base 200, so as to provide a certain supporting effect for the camera 100. Of course, besides the two embodiments, other ways may be used to ensure that the camera head 100 can rotate relative to the support base 200 and can contact the support base 200 through the heat dissipation guide 410 and the heat-conducting rolling balls 300 when the heat dissipation guide 410 with the above structure is adopted.

In this case, the radius of the heat-conducting rolling ball 300 mounted on the first heat-dissipating guide rail 411 may be equal to the radius of the heat-conducting rolling ball 300 mounted on the second heat-dissipating guide rail 412, so as to reduce the difficulty of spare parts, and on the other hand, the heat-conducting rolling balls 300 with substantially the same rotation condition provide a rolling support effect for the camera 100, thereby further improving the motion stability of the camera 100.

Based on the above embodiment, the sinking groove 221 may be formed on the supporting base 200, and the groove surface of the sinking groove 221 is a spherical structure, so that the plurality of heat-conducting rolling balls 300 engaged with the first heat-dissipating guide rail 411 and the second heat-dissipating guide rail 412 are supported in the sinking groove 221, thereby further improving the engagement stability between the camera 100 and the supporting base 200.

Specifically, the positioning portion 420 may have a sheet structure, and the radius of the through holes 421 may be determined according to the radius of each of the heat-conductive rolling balls 300, and specifically, the radius of each of the through holes 421 may be smaller than the radius of the heat-conductive rolling ball 300 corresponding to the through hole 421, so as to ensure that the heat-conductive rolling ball 300 does not come off from the through hole 421. The positioning portion 420 and the camera head 100 may be fixed to each other by welding or gluing, and the plurality of heat-conducting rolling balls 300 are all sandwiched between the positioning portion 420 and the camera head 100.

More specifically, when the shape of the positioning portion 420 is adapted to the shape of the surface of the camera 100 facing the support base 200, and when the heat-conducting rolling ball 300 is in contact with the surface of the camera 100, the distance between the position of each through hole 421 in the positioning portion 420 and the camera 100 is greater than the radius of the heat-conducting rolling ball 300 corresponding to the through hole 421 and smaller than the diameter of the heat-conducting rolling ball 300 corresponding to the through hole 421, and at the same time, the distance needs to be matched with the radius of the through hole 421, specifically, the sum of the distance and the height of the portion of the heat-conducting rolling ball 300 extending out of the positioning portion 420 may be greater than the diameter of the heat-conducting rolling ball 300 corresponding to the position, so as to ensure that the heat-conducting rolling ball 300 mounted at the through hole 421 can rotate at the through hole 421 and does not separate from the through hole 421.
