[0025] Shell 100 is the basic component of vehicle-mounted storage device, shell 100 is used to provide the installation base for other components of vehicle-mounted storage device, wherein, storage medium 200, transmission connector 300 and heat dissipation part 400 are all arranged in shell 100.In addition, shell 100 is also used to form some functional space or structure, for example, inner cavity 110, avoiding hole 120, heat dissipation hole 130, first positioning groove 140 and second positioning groove 150 etc.

[0026] Storage medium 200 is the core component for storing data in vehicle-mounted storage device, transmission connector 300 is the core component for realizing data transmission in vehicle-mounted storage device, heat dissipation part 400 is the core component for dissipating the heat generated by storage medium 200 in vehicle-mounted storage device.Storage medium 200 and heat dissipation part 400 are both arranged in inner cavity 110, avoiding hole 120 is communicated with inner cavity 110, transmission connector 300 passes through avoiding hole 120 and extends to inner cavity 110 and is connected with storage medium 200.Meanwhile, heat dissipation hole 130 is communicated with inner cavity 110, heat dissipation part 400 is connected with storage medium 200, and heat dissipation part 400 dissipates the heat generated by storage medium 200 to the outside of shell 100 through heat dissipation hole 130.

[0027] Specifically, the transmission connector 300 can be electrically connected with the storage medium 200, so that the storage medium 200 can be connected with a vehicle-mounted system (for example, a car multimedia system) or a vehicle-mounted device (for example, a driving recorder) through the transmission connector 300, thereby enabling data to be transmitted into the storage medium 200 through the transmission connector 300, so as to realize storage of the data in the storage medium 200, or the data in the storage medium 200 can also be read through the transmission connector 300.

[0028] Optionally, the material of the shell 100 can be plastic or wood, and the material of the heat dissipation part 400 can be metal, alloy or heat-conducting ceramic. The specific materials of the shell 100 and the heat dissipation part 400 are not limited in the embodiments of the present application. In addition, the transmission connector 300 can be a USB Type-C plug or a USB Type-A plug, and the specific structure of the transmission connector 300 is not limited in the embodiments of the present application.

[0029] The vehicle-mounted storage device disclosed in the embodiments of the present application improves the structure of the vehicle-mounted storage device related to the prior art. The heat dissipation part 400 is arranged in the inner cavity 110, and the heat dissipation part 400 is connected with the storage medium 200 in the inner cavity 110, so that the heat generated by the storage medium 200 can be transferred to the heat dissipation part 400. The heat dissipation holes 130 are arranged on the shell 100, so that the heat dissipation part 400 can dissipate the heat generated by the storage medium 200 to the outside of the shell 100 through the heat dissipation holes 130, thereby dissipating the heat generated by the storage medium 200 in time, so as to avoid the situation that the temperature of the vehicle-mounted storage device is too high and the user is easily scalded.

[0030] In order to dissipate heat more efficiently, the heat dissipation holes 130 can be multiple, and the multiple heat dissipation holes 130 can be arranged around the heat dissipation part 400, so that the heat dissipation part 400 can dissipate heat to the outside of the shell 100 through the multiple heat dissipation holes 130, which is beneficial to improve the heat dissipation efficiency, thereby further reducing the risk that the temperature of the vehicle-mounted storage device is too high and the user is easily scalded.

[0031] In further technical solutions, the heat dissipation part 400 and the cavity wall of the inner cavity 110 can surround the heat dissipation space 111, the inner cavity 110 can include the heat dissipation space 111, and the heat dissipation holes 130 can be in communication with the heat dissipation space 111. This structure enables the heat dissipation part 400 to transfer heat to the heat dissipation space 111, and then quickly dissipate the heat from the heat dissipation holes 130 to the outside of the shell 100 through the heat dissipation space 111. This structure can buffer through the heat dissipation space 111 to avoid the situation that the heat dissipation part 400 transfers too much heat to the shell 100, which easily leads to an increase in the temperature of the shell 100 and easily scalds the user, thereby further reducing the risk that the vehicle-mounted storage device scalds the user.

[0032] In a feasible technical solution, the heat dissipation part 400 can have a heat dissipation surface 410, the heat dissipation surface 410 and the cavity wall of the inner cavity 110 can enclose a heat dissipation space 111, and the heat dissipation surface 410 can be provided with a plurality of first heat dissipation ribs 411. In this structure, when the heat dissipation part 400 dissipates heat, the heat dissipation surface 410 can be in contact with the air to exchange heat with the air, and the plurality of first heat dissipation ribs 411 can also be in contact with the air to exchange heat with the air, so that the contact area of the heat dissipation part 400 and the air can be increased by the plurality of first heat dissipation ribs 411, and the heat dissipation can be more efficient.

[0033] In addition, in this structure, a plurality of first flow guide grooves 412 can be formed between the plurality of first heat dissipation ribs 411, respectively, and the plurality of first flow guide grooves 412 can respectively penetrate to the two opposite sides of the heat dissipation part 400, so that the air can flow in the plurality of first flow guide grooves 412, and the heat dissipation effect can be enhanced.

[0034] Further, the heat dissipation surface 410 can also be provided with a plurality of second heat dissipation ribs, and the extension directions of the plurality of second heat dissipation ribs can respectively intersect or be out of the extension directions of the plurality of first heat dissipation ribs 411. This structure can further increase the contact area of the heat dissipation part 400 and the air through the plurality of second heat dissipation ribs, so that the heat dissipation can be more efficient.

[0035] In addition, in this structure, a plurality of second flow guide grooves can be formed between the plurality of second heat dissipation ribs, respectively, and the plurality of second flow guide grooves can respectively penetrate to the other two opposite sides of the heat dissipation part 400, so that the air can flow in the plurality of second flow guide grooves. At the same time, the plurality of second flow guide grooves can be respectively communicated with the plurality of first flow guide grooves 412, so that the resistance of the air flow can be reduced, the air flow can be more convenient, and the heat dissipation effect can be enhanced.

[0036] Optionally, the extension directions of the plurality of second heat dissipation ribs can respectively be perpendicular to the extension directions of the plurality of first heat dissipation ribs. In this structure, the plurality of second flow guide grooves and the plurality of first flow guide grooves 412 are all perpendicular, so that the air flow can be better guided, the flow speed and flow rate of the air can be improved, and the heat dissipation effect can be enhanced.

[0037] In the embodiment of the present application, the vehicle-mounted storage device can further include a heat-conducting pad 500, which can be arranged in the inner cavity 110 and clamped between the heat-dissipating part 400 and the storage medium 200, so as to effectively fill the gap between the heat-dissipating part 400 and the storage medium 200 through the heat-conducting pad 500, and enable the heat-dissipating part 400 and the storage medium 200 to be in close contact through the heat-conducting pad 500, so that the storage medium 200 can efficiently transfer heat to the heat-dissipating part 400 through the heat-conducting pad 500, thereby improving the heat conduction efficiency. Specifically, the heat-conducting pad 500 can be made of silicone grease, silicone rubber or epoxy resin, and the present application is not limited in this regard.

[0038] In a feasible technical solution, the shell 100 can further have a first positioning groove 140 and a second positioning groove 150, which are oppositely arranged and can respectively communicate with the inner cavity 110. The heat-dissipating part 400 can include a heat-dissipating body 420, a first positioning protrusion 430 and a second positioning protrusion 440, which can be oppositely and spacedly connected to the heat-dissipating body 420 and can be respectively positioned in the first positioning groove 140 and the second positioning groove 150. Such a structure enables the installation of the heat-dissipating part 400 to be guided by the positioning cooperation between the first positioning protrusion 430 and the second positioning protrusion 440 and the first positioning groove 140 and the second positioning groove 150 when the heat-dissipating part 400 is installed into the inner cavity 110, thereby facilitating the installation of the heat-dissipating part 400.

[0039] In addition, the heat-dissipating body 420 can include a heat-dissipating surface 410, in which case the first positioning protrusion 430 and the second positioning protrusion 440 can be arranged on the side of the heat-dissipating body 420 opposite to the heat-dissipating surface 410. Meanwhile, such a structure enables the positioning of the heat-dissipating body 420 in the inner cavity 110 to be achieved by the positioning cooperation between the first positioning protrusion 430 and the second positioning protrusion 440 and the first positioning groove 140 and the second positioning groove 150, so that the heat-dissipating surface 410 and the cavity wall of the inner cavity 110 can enclose the heat-dissipating space 111.

[0040] Meanwhile, an accommodation space 600 can be formed between the first positioning protrusion 430 and the second positioning protrusion 440, and the heat-conducting pad 500 and the storage medium 200 can be arranged in the accommodation space 600, and the heat-conducting pad 500 can be clamped between the storage medium 200 and the heat-dissipating body 420. Such a structure can concentrate the heat-conducting pad 500 and the storage medium 200 in the accommodation space 600, so that the structure among the heat-dissipating body 420, the heat-conducting pad 500 and the storage medium 200 is more compact, and the space occupation of the inner cavity 110 can be reduced.

[0041] In order to improve the overall strength of the heat dissipation part 400 and reduce the assembly cost, the heat dissipation body 420, the first positioning protrusion 430 and the second positioning protrusion 440 can be an integral structure. Of course, the heat dissipation body 420, the first positioning protrusion 430 and the second positioning protrusion 440 can also be a split structure, so that the heat dissipation body 420, the first positioning protrusion 430 and the second positioning protrusion 440 can be produced respectively, and the difficulty of design and production can be reduced.

[0042] In an optional technical solution, the first positioning protrusion 430 and the second positioning protrusion 440 can be respectively provided with a first slot 431 and a second slot 441, and the two opposite ends of the storage medium 200 can be respectively inserted into the first slot 431 and the second slot 441 to clamp the heat-conducting pad 500 between the storage medium 200 and the heat dissipation body 420. This structure can avoid the need for additional components to fix the heat-conducting pad 500 and the storage medium 200, so that the first positioning protrusion 430 and the second positioning protrusion 440 can be more fully utilized, thereby facilitating cost savings.

[0043] Of course, in other embodiments, the vehicle-mounted storage device can also include a connecting piece, wherein the connecting piece can be a screw or a bolt, and the connecting piece can pass through the storage medium 200 and be connected to the heat dissipation body 420, thereby achieving the connection between the storage medium 200 and the heat dissipation body 420 and allowing the heat-conducting pad 500 to be pressed between the storage medium 200 and the heat dissipation body 420. This structure is relatively simple and easy to implement.

[0044] In one embodiment, the shell 100 can include a shell body 160 and a cover 170, the shell body 160 can have an opening 161, the cover 170 can be sealed to the opening 161, and can form an inner cavity 110 with the shell body 160, the heat dissipation hole 130 can be provided on the shell body 160, and the avoidance hole 120 can be provided on the cover 170. Specifically, the cover 170 can be sealed to the opening 161 by welding or bonding. This structure is relatively simple and easy to implement, and facilitates the installation of the storage medium 200, the transmission connector 300 and the heat dissipation part 400.

[0045] Further, the cover 170 can have a surrounding protrusion 171, the surrounding protrusion 171 can be provided outside the inner cavity 110, the surrounding protrusion 171 can surround the avoidance hole 120 and can surround the transmission connector 300. This structure reduces the risk of loosening of the connection between the transmission connector 300 and the storage medium 200 caused by the shaking of the transmission connector 300 when subjected to impact, thereby facilitating the improvement of the stability of the transmission connector 300.
