[0035] The following will introduce the chip heat dissipation structure and the shooting auxiliary device provided by the present utility model according to the attached Figure 1 to the attached Figure 2 drawings.

[0036] As Figure 1 shown, in this embodiment, the chip heat dissipation structure is mainly used for shooting auxiliary devices or shooting devices such as a handheld camera stabilizer, a gimbal, and a handheld camera. Specifically, the chip heat dissipation structure includes a housing 1, a motor, a chip, and a first heat conducting connector 5. Among them, the housing 1 serves as a handheld part, enabling a shooting operator to move the shooting auxiliary device or the shooting device by grasping the housing 1. In this embodiment, the housing 1 is made of a non-metallic material, especially a plastic material, a wood material, etc. with skin-friendly characteristics and good handheld experience, so as to improve the use experience of the shooting operator. It should be noted that the heat conduction performance of these non-metallic materials is worse than that of metal materials, and during the handheld process, the heat conduction efficiency between the non-metallic materials and the human hand is worse than that between the non-metallic materials and the air. Therefore, the housing 1 has at least two limitations in terms of material and heat conduction path, resulting in a relatively low heat dissipation efficiency through the housing 1.

[0037] The motor is disposed at one end of the housing 1 and can be drivingly connected to key components of the camera or imaging, such as a lens, a CMOS, etc., so as to move the shooting perspective, realize the change of the perspective and the stability of the picture. Exemplarily, in some embodiments, taking a single motor connected to the camera as an example, during the process of shooting a panoramic work, by rotating the camera with a single motor, the orientation of the camera can be rotated during the process of shooting the panoramic work to change the shooting perspective, and a panoramic work can be obtained by means of picture stitching. Of course, in some other embodiments, taking multiple motors connected in sequence and finally drivingly connected to the camera as an example, the multiple motors form a multi-axis linkage mode, and can adjust the shooting perspective of the camera along multiple axes simultaneously, so as to achieve the effect of moving the shooting perspective, and of course, the shooting perspective can also be stabilized. At the same time, the motor has a metal shell 3 to ensure the structural strength of the motor itself and also facilitate convective heat dissipation with the air to dissipate the heat generated during the operation of the motor itself.

[0038] The chip is disposed inside the housing 1, and the housing 1 protects the chip, achieving the effects of rainproof and dustproof. The chip can be connected to a control terminal (such as a mobile phone), a camera or a sensor connected to the housing 1, and calculates corresponding driving instructions according to the settings of the mobile phone app, the data transmitted by the camera or the sensor. The chip is electrically connected to the motor, and the motor can receive the driving instructions and act according to the driving instructions to realize the rotation or movement of the camera or the key imaging components, and achieve the effects of moving the perspective or stabilizing the picture.

[0039] One end of the first heat-conducting connector 5 is in heat-conducting connection with the chip, and the other end of the first heat-conducting connector 5 passes through the housing 1 and is in heat-conducting connection with the metal shell 3 of the motor located outside the housing 1. The heat generated by the chip during operation can be transferred to the metal shell 3 through the first heat-conducting connector 5, and then through the convective heat dissipation between the metal shell 3 and the air, so as to realize the heat dissipation of the chip.

[0040] This chip heat dissipation structure can transfer the heat generated by the chip to the metal shell 3 of the motor through the first heat-conducting connector 5 and dissipate the heat through the convective heat dissipation between the metal shell 3 and the air, thus breaking through the multiple restrictions on chip heat dissipation by the handheld housing 1. While achieving a better handheld experience, it realizes efficient heat dissipation of the chip, making the chip not easy to accumulate heat and able to maintain an appropriate working temperature, meeting the requirements of long-term handheld shooting.

[0041] Specifically, as Figure 2As shown, in this embodiment, the housing 1 is columnar for easy hand-holding. The first heat conduction connector 5 includes a first part and a second part arranged parallel to the axial direction of the housing 1, and the first part and the second part are connected. Among them, the first part is in heat conduction connection with the chip and can conduct the heat generated by the chip during operation to the first heat conduction connector 5. One end of the second part is connected to the first part, and the end of the second part far from the first part passes through the housing 1 and abuts against the metal housing 3 of the motor, and can conduct the heat of the first heat conduction connector 5 to the metal housing 3. The metal housing 3 is located outside the housing 1 and is not used as a hand-held part, and can have relatively efficient convective heat dissipation with the air, so as to quickly transfer the heat generated by the chip outside the housing 1.

[0042] Preferably, in this embodiment, a heat-conducting silica gel part 6 is clamped between the chip and the first heat conduction connector 5. The heat-conducting silica gel part 6 has a certain deformation ability and can ensure the contact area between the heat-conducting silica gel part 6 and the chip and the first heat conduction connector 5 when abutting against the chip and the first heat conduction connector 5, so as to ensure the heat transfer efficiency between the heat-conducting silica gel part 6 and the chip and the first heat conduction connector 5, realize efficient heat transfer, and avoid heat accumulation and overheating of the chip.

[0043] Exemplarily, in this embodiment, the first heat conduction connector 5 is provided with a recessed part and a through hole, and the inner side of the housing 1 is provided with a protruding part and a threaded hole. The threaded fastener can pass through the through hole and be connected to the threaded hole, and the protruding part can be inserted into the recessed part in a limited way, so as to fixedly arrange the first heat conduction connector 5 in the housing 1 and press the heat-conducting silica gel part 6 onto the chip, ensuring the stable abutment between the heat-conducting silica gel part 6 and the chip and the first heat conduction connector 5.

[0044] Of course, in some other embodiments, the first heat conduction connector 5 can also be fixed inside the housing 1 only by the way of snap limit, or only by the way of threaded connection, or by other fixing methods such as adhesive connection, and these also fall within the scope of protection of the present utility model.

[0045] As Figure 2 shown, in this embodiment, a battery 7 is also arranged inside the housing 1. The battery 7, the motor and the chip are electrically connected. The battery 7 can provide electrical energy for the rotation of the motor and the calculation of the chip, and the chip can also manage the electrical energy input and output of the battery 7. Along the axial direction of the housing 1, a heat insulation part 8 is arranged between the battery 7 and the first heat conduction connector 5, which can prevent the heat generated during the electrical energy input and output of the battery 7 from being transferred to the chip through the first heat conduction connector 5, resulting in a negative impact on the normal heat dissipation process of the chip. At the same time, the first heat conduction connector 5, the heat insulation part 8 and a part of the housing 1 can limit the battery 7 and can also enhance the stability of the overall structure. In this embodiment, the heat insulation part 8 is made of foam.

[0046] Optionally, in this embodiment, the chip includes a first chip 41 and a second chip 42. The first chip 41 and the second chip 42 are arranged axially along the housing 1, and a heat-conducting silica gel member 6 is abutted between the first chip 41 and the second chip 42. By providing the first chip 41 and the second chip 42, on the premise of achieving a suitable diameter of the housing 1 for grasping, chips of appropriate size can be provided to meet the demand for computing power, and the axial length of the housing 1 will not be too long, ensuring the experience of handheld shooting. Of course, in some other embodiments, a single chip with a better process and stronger computing power can also be used to achieve large-capacity computing and further optimization of structure and weight. Although its manufacturing cost will increase accordingly, it still falls within the scope protected by the present utility model.

[0047] Among them, both the first chip 41 and the second chip 42 are arranged in a direction parallel to the radial direction of the housing 1. The first chip 41 is located between the second chip 42 and the first heat-conducting connector 5. The first part of the first heat-conducting connector 5 is arranged in a direction parallel to the radial direction of the housing 1, and is thermally connected to the first chip 41 through the heat-conducting silica gel member 6, and a relatively large heat-conducting transmission area is achieved, which is beneficial to transferring the heat of the first chip 41 to the outside of the housing 1.

[0048] At the same time, another heat-conducting silica gel member 6 is also abutted between the first chip 41 and the second chip 42, so that the heat generated by the second chip 42 can be transferred to the first chip 41 through the heat-conducting silica gel member 6, and is exchanged to the air through the first heat-conducting connector 5 and the metal housing 3 of the motor.

[0049] Furthermore, in this embodiment, the other end of the housing 1 is provided with an opening, and a bottom cover 2 is installed to close the opening. This opening can be used to install components such as the battery 7, the chip, and the first heat-conducting connector 5 into the housing 1, and the bottom cover 2 can play a role in closing the opening to achieve the effects of waterproofing and dustproofing. The chip is thermally connected to the bottom cover 2, which can dissipate heat through the bottom cover 2 in parallel while dissipating heat through the first heat-conducting connector 5, so as to further improve the heat dissipation efficiency of the chip and ensure its working temperature under large computing loads.

[0050] Preferably, in this embodiment, a heat-conducting silica gel member 6 and a second heat-conducting connector 9 are thermally connected between the second chip 42 and the bottom cover 2. The heat-conducting silica gel member 6 is abutted between the second chip 42 and the second heat-conducting connector 9, and the second heat-conducting connector 9 is thermally connected to the bottom cover 2. Through the heat-conducting silica gel member 6 and the second heat-conducting connector 9, heat can be quickly transferred to the bottom cover 2 for heat dissipation. At the same time, the second heat-conducting connector 9 can also play an auxiliary fixing effect to prevent gaps from appearing between the second chip 42 and the bottom cover 2, thereby avoiding phenomena such as movement and looseness.

[0051] Of course, in some other embodiments, the second heat conduction connector 9 can also be directly heat-conductively connected between the second chip 42 and the bottom cover 2, or the heat-conductive silicone member 6 can be directly connected, which also falls within the scope of protection of the present utility model.

[0052] The present utility model also provides a shooting auxiliary device, which includes the above chip heat dissipation structure. Among them, the heat generated by the chip is transferred to the metal shell 3 of the motor through the first heat conduction connector 5, and the heat is dissipated through the convection heat dissipation between the metal shell 3 and the air, thereby breaking through the multiple restrictions of the handheld housing 1 on chip heat dissipation. While achieving a better handheld experience, efficient heat dissipation of the chip is realized, so that the chip is not easily heated up, can maintain an appropriate working temperature, and meets the requirements of long-term handheld shooting.

[0053] Obviously, the above embodiments of the present utility model are only examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
