[0034] First see Figures 1 to 3The utility model provides a heat dissipation rabbit cage 10, which is used to assist a camera or other shooting equipment to take pictures. The camera is installed on the heat dissipation rabbit cage 10, thereby increasing the use scenarios of the camera. The shooting equipment can also be a mobile device capable of taking pictures. The heat dissipation cage 10 comprises a frame 100 and a heat dissipation back plate 200. The frame 100 encloses an installation space 110 for installing a camera. The installation space 110 has a front opening 111 and a rear opening 112 which are opposite to each other along the depth direction thereof. An installation position 160 for installing photography auxiliary equipment is arranged on the outer side of the frame 100. The heat dissipation back plate 200 is fixedly connected to the frame 100. The heat dissipation back plate 200 is located on the side where the rear opening 112 is located, and the heat dissipation back plate 200 covers at least a part of the rear opening 112. The thickness direction of the heat dissipation back plate 200 is parallel to the depth direction of the installation space 110. The heat dissipation back plate 200 can conduct the heat of the camera to the frame 100 for heat dissipation, so that when the camera is installed in the heat dissipation cage 10 and is used for a long time, the heat dissipation cage 10 can dissipate the heat of the camera in time to reduce the temperature of the camera, thereby ensuring the performance and service life of the camera.

[0035] refer to Figure 1 and Figure 2 The frame 100 encloses a circumferentially closed installation space 110, and the camera is installed in the installation space 110. The front opening 111 of the installation space 110 is used to display the camera screen, and the rear opening 112 is used for the camera head to take pictures and collect light. The heat dissipation back plate 200 covers a part of the rear opening 112, and the heat dissipation back plate 200 avoids the camera head area of ​​the camera at the same time. It should be noted that the frame 100 can also be a circumferentially non-closed structure. For example, the frame 100 is composed of at least three sides, and the frame 100 encloses an installation space 110 with a gap.

[0036] The heat dissipation back plate 200 is a heat-conducting metal plate, such as a copper plate, an aluminum plate and alloys thereof. The heat dissipation back plate 200 can conduct heat. When the camera is installed in the installation space 110, the heat dissipation back plate 200 fits the camera. The heat generated by the camera during use can be conducted to the heat dissipation back plate 200. The heat dissipation back plate 200 conducts the heat to the frame 100 through its own thermal conductivity, thereby increasing the heat dissipation area and quickly reducing the temperature of the camera. It should be noted that the heat dissipation back plate 200 can also be made of a heat-conducting colloid, such as silicone thermal conductive glue, acrylic thermal conductive glue, polyurethane thermal conductive glue, etc.

[0037] In one embodiment, the heat dissipation rabbit cage 10 also includes a thermally conductive adhesive layer, which has adhesiveness and thermal conductivity, so that the thermally conductive adhesive layer can adhere to metal thermal conductive materials such as copper and aluminum. The thermally conductive adhesive layer is located between the heat dissipation back plate 200 and the frame 100. The heat dissipation back plate 200 is bonded to the frame 100 through the thermally conductive adhesive layer to achieve a quick and fixed connection between the heat dissipation back plate 200 and the frame 100. The thermally conductive adhesive layer can be silicone thermally conductive adhesive, acrylic thermally conductive adhesive, polyurethane thermally conductive adhesive, etc.

[0038] In the present embodiment, the heat dissipation rabbit cage 10 further includes a connector 300, which is used to detachably connect the heat dissipation back plate 200 to the frame 100. The connector 300 includes a plurality of threaded connectors 310. A first threaded hole 210 is provided at the position where the heat dissipation back plate 200 is connected to the frame 100. A second threaded hole 120 is provided at the position where the frame 100 is connected to the heat dissipation back plate 200. The first threaded hole 210 is positioned relative to the second threaded hole 120. The threaded connector 310 is respectively penetrated by the first threaded hole 210 and the second threaded hole 120, so that the threaded connector 310 is respectively threadedly connected to the heat dissipation back plate 200 and the frame 100. When the threaded connector 310 is tightened, the heat dissipation back plate 200 is directly abutted against the frame 100, and the heat of the camera can be conducted to the frame 100 through the heat dissipation back plate 200, thereby increasing the heat dissipation area. The first threaded hole 210 The first and second threaded holes 120 are respectively provided with a plurality of them, so that the three adjacent side frames of the frame 100 are all connected to the heat dissipation back plate 200 to increase the stability of the connection between the heat dissipation back plate 200 and the frame 100. The frame 100 can also be connected to the heat dissipation back plate 200 by the opposite side frames. It can be understood that the heat dissipation back plate 200 itself has thermal conductivity. While the heat dissipation back plate 200 transfers heat to the frame 100, the heat of the camera can also be directly dissipated through the heat dissipation back plate 200. It should be noted that the connecting member 300 can also be a bite structure. For example, the bite structure is provided on one of the heat dissipation back plate 200 and the frame 100, and the other is provided with a bite block for the bite structure to be bite-fixed. When the heat dissipation back plate 200 is attached to the frame 100, the bite structure is moved and bites with the bite block, so that the heat dissipation back plate 200 is fixedly connected to the frame 100.

[0039] refer to Figure 3The heat dissipation rabbit cage 10 also includes a thermally conductive film 400, which is attached to a side surface of the heat dissipation back plate 200 facing the front end opening 111. The thermally conductive film 400 has thermal conductivity. When the camera is installed in the installation space 110, the thermally conductive film 400 is attached to the camera, and the heat of the camera is transferred to the heat dissipation back plate 200 through the thermally conductive film 400, and the heat dissipation back plate 200 dissipates heat. The thermally conductive film 400 is made of a soft material, and when the camera is installed in the installation space 110, the thermally conductive film 400 is located between the camera and the heat dissipation back plate 200, thereby preventing the camera from directly contacting the metal heat dissipation back plate 200 and wearing the camera. It should be noted that in other embodiments, when the heat dissipation back plate 200 is made of the above-mentioned colloid that can conduct heat, the thermally conductive film 400 may not be set, and the heat dissipation back plate 200 is a soft material to prevent the camera from being worn.

[0040] refer to Figure 3 A plurality of heat dissipation grooves 220 arranged at intervals are provided on a surface of the heat dissipation back plate 200 facing the front end opening 111. The thermal conductive film 400 is formed on the heat dissipation back plate 200 to be bonded to the heat dissipation back plate 200. At the same time, a positioning protrusion is protruded from a side of the heat dissipation back plate 200 that is in contact with the heat dissipation back plate 200. The positioning protrusion matches the heat dissipation groove 220. When the thermal conductive film 400 is in contact with the surface of the heat dissipation back plate 200 facing the front end opening 111, the positioning protrusion just extends and fills the heat dissipation groove 220. The surface of the positioning protrusion is in contact with the groove wall of the heat dissipation groove 220, thereby increasing the contact area between the thermal conductive film 400 and the heat dissipation back plate 200, so as to increase the heat conduction area of ​​the thermal conductive film 400 and improve the heat dissipation effect.

[0041] It should be noted that, in one embodiment, a plurality of heat dissipation grooves 220 are respectively arranged on a side surface of the heat dissipation back plate 200 facing the front end opening 111, and the heat dissipation grooves 220 extend to the edge of the heat dissipation back plate 200 and are connected to the outside world, the thermal conductive film 400 covers at least part of the heat dissipation grooves 220, and the side of the thermal conductive film 400 that is in contact with the heat dissipation back plate 200 is a flat plane, or the positioning protrusions on the thermal conductive film 400 are not completely filled into the heat dissipation grooves 220, so that outside air can enter the heat dissipation grooves 220 and take away part of the heat on the surface of the thermal conductive film 400, and at the same time, the thermal conductive film 400 can also transfer heat to the heat dissipation back plate 200 through the area in contact with the heat dissipation back plate 200, so as to dissipate heat through the heat dissipation back plate 200. It can be understood that the heat dissipation grooves 220 can extend from one side edge of the heat dissipation back plate 200 to the edge of the other opposite side, so that outside air can circulate.

[0042] In one embodiment, a plurality of heat dissipation grooves 220 are respectively arranged on a side surface of the heat dissipation back plate 200 facing the front end opening 111, and the heat dissipation grooves 220 extend to the edge of the heat dissipation back plate 200 and are connected to the outside. The thermal conductive film 400 is not provided, and the camera is directly attached to the side surface of the heat dissipation back plate 200 facing the front end opening 111. The outside air circulates through the heat dissipation grooves 220, thereby taking away part of the heat on the camera surface. The area where the camera contacts the heat dissipation back plate 200 transfers the heat to the side facing away from the camera and the frame 100 through the heat dissipation back plate 200, thereby increasing the heat dissipation area and improving the heat dissipation effect.

[0043] refer to Figure 2 The heat dissipation back plate 200 and the thermal conductive film 400 are both provided with avoidance holes 230. The two avoidance holes 230 are aligned with each other. The avoidance holes 230 are used to avoid the functional interface of the camera. At the same time, the avoidance holes 230 can also allow air circulation to accelerate the heat dissipation of the camera.

[0044] refer to Figure 3 The surface of one side of the heat dissipation back plate 200 facing the front end opening 111 is recessed to form an avoidance groove 240. The avoidance groove 240 is used to avoid the portion of the camera protruding from the installation space 110. The shape of the avoidance groove 240 is the same as the shape of the portion of the camera protruding from the installation space 110, so that the portion of the camera protruding from the installation space 110 can fit with the groove wall of the avoidance groove 240. It can be understood that when the portion where the camera fits with the heat dissipation back plate 200 is a flat plane, the avoidance groove 240 may not be set.

[0045] refer to Figure 4 The frame 100 includes a fixed frame 140, a movable frame 130 and a locking member 150. The fixed frame 140 and the movable frame 130 enclose an installation space 110. One end of the movable frame 130 is connected to the fixed frame 140 by a rotating structure, such as a hinge structure, so that the movable frame 130 can rotate relative to the fixed frame 140. The locking member 150 is used to lock the movable frame 130 and the fixed frame 140. When the movable frame 130 rotates relative to the fixed frame 140 and is in an open state, the installation space 110 forms an installation opening on one side perpendicular to the depth direction. Opening 113, at this time, the camera can enter the installation space 110 through the installation opening 113, when the movable frame 130 rotates relative to the fixed frame 140 to be in a closed state, the movable frame 130 closes the installation opening 113, at this time, the locking member 150 is turned, the locking member 150 is respectively connected to the movable frame 130 and the fixed frame 140, the rotation of the movable frame 130 is restricted and fixed relative to the fixed frame 140, the camera is fixed in the installation space 110, it can be understood that when the movable frame 130 is in a closed state, at least two ends of the movable frame 130 are in contact with the fixed frame 140.

[0046] In one embodiment, reference Figure 4 The locking member 150 is a threaded rod 151. The movable frame 130 is provided with a first threaded hole 132 at a position where it abuts against the fixed frame 140. The first hole 132 passes through the movable frame 130. The fixed frame 140 is provided with a second threaded hole 142. When the movable frame 130 is in a closed state and abuts against the fixed frame 140, the second hole 142 is positioned relative to the first hole 132. After the camera is installed in the installation space 110, the movable frame 130 is rotated to close the installation opening 113. The threaded rod 151 passes through the first hole 132 and is threadedly connected to the second hole 142 under the rotation of an external force, so that the threaded rod 151 is threadedly connected to the second hole 142 respectively. The threaded rod 151 is connected to the movable frame 130 and the fixed frame 140, so that the movable frame 130 and the fixed frame 140 are relatively fixed. The threaded rod 151 is also provided with an anti-slip pattern 1511. When the user rotates the threaded rod 151 to be threadedly connected to the movable frame 130 and the fixed frame 140, the anti-slip pattern 1511 can increase the friction between the fingers and make it more convenient to twist. It can be understood that the threaded rod 151 can be always movably connected to the movable frame 130 and rotate with the movable frame 130, so as to prevent the threaded rod 151 from falling off and being lost. The threaded rod 151 can also be an independent component that can be separated from the movable frame 130 and the fixed frame 140.

[0047] In one embodiment, reference Figure 5 and Figure 6 The locking member 150 is a snap-fit ​​plate 152, and the snap-fit ​​plate 152 is provided with a snap-fit ​​block 1521. The snap-fit ​​plate 152 is rotatably provided on one of the movable frame 130 and the fixed frame 140, and the other is provided with a fixed block 141. In this embodiment, the snap-fit ​​plate 152 is rotatably provided on the movable frame 130 and can rotate with the movable frame 130, and the fixed block 141 is provided on the fixed frame 140. The fixed block 141 and the snap-fit ​​plate 152 cooperate with each other. When the movable frame 130 closes the installation opening 113, the movable frame 130 abuts against the fixed frame 140, and the snap-fit ​​plate 152 is rotated to the position of the fixed block 141 so that the snap-fit ​​block 1521 and the fixed block 141 abut and bite each other, so that the snap-fit ​​plate 152 is respectively connected to the movable frame 130 and the fixed frame 140, the movable frame 130 and the fixed frame 140 are relatively fixed, and the camera is fixed in the installation space 110.

[0048] The buckling plate 152 includes a plate body 1522, a rotating shaft 1523 and a torsion spring 1524. The rotating shaft 1523 penetrates the plate body 1522 in a thickness direction perpendicular to the plate body 1522. The movable frame 130 is provided with a rotating space 131 for the buckling plate 152 to rotate. The rotating shaft 1523 passes through the plate body 1522 and the opposite two ends are respectively abutted against the two opposite side walls of the rotating space 131. The rotating shaft 1523 is limited in the rotating space 131. The plate body 1522 can rotate relative to the movable frame 130 around the rotating shaft 1523. The buckling block 1521 is fixedly arranged on the plate body 1522. The torsion spring 1524 is sleeved on the rotating shaft 1523. One of the two rotating arms of the torsion spring 1524 is fixed to the movable frame 130, and the other is abutted against the plate body 1522. The rotating arms of the buckling block 1521 and the torsion spring 1524 are respectively located on both sides of the rotating shaft 1523. 24 always releases the elastic force and drives the plate body 1522 to rotate in the positive direction around the rotating shaft 1523. When the plate body 1522 rotates forward, the snap block 1521 rotates in the direction close to the fixed block 141, the snap block 1521 and the fixed block 141 bite each other, and the movable frame 130 and the fixed frame 140 are relatively fixed. When the plate body 1522 rotates in the opposite direction under the action of external force, the snap block 1521 is separated from the fixed block 141, the torsion spring 1524 accumulates elastic force, the limit of the movable frame 130 relative to the fixed frame 140 is released, the movable frame 130 is rotated, and the installation opening 113 is opened. It should be noted that the torsion spring 1524 can also be not provided, and the plate body 1522 rotates around the rotating shaft 1523 through damping. When the snap block 1521 and the fixed block 141 are bite-fixed with each other, it can also prevent the snap block 1521 from being separated from the fixed block 141 without the action of external force.

[0049] The locking member 150 may also be other structures, such as two magnets respectively arranged on the fixed frame 140 and the movable frame 130, which limit the movable frame 130 relative to the fixed frame 140 by magnetic attraction and fixation. As long as the locking member 150 can limit the movable frame 130 and the fixed frame 140 relative to each other, it is within the protection scope of the present application.

[0050] refer to Figure 1 and Figure 2 The mounting position 160 on the outside of the frame 100 is a cold shoe slot or a threaded connection port. The mounting position 160 is used to quickly connect photography auxiliary equipment, such as a fill light or a tripod mount, etc. There are multiple mounting positions 160, and the multiple mounting positions 160 are respectively arranged on the movable frame 130 and the fixed frame 140.
