Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerators, in particular to a protection structure for a control box of a new energy vehicle-mounted refrigerator. Background Technique

[0002] The control box with a circuit board of the existing vehicle-mounted refrigerator is often installed in the same electrical compartment together with the compressor. This leads to unsatisfactory heat dissipation of the control box. Moreover, when performing maintenance, it is necessary to open the electrical compartment, which is not convenient for maintenance. In addition, the control box also occupies the internal space of the main body of the vehicle-mounted refrigerator, resulting in a larger volume of the electrical compartment and a larger volume of the entire main body of the vehicle-mounted refrigerator. For example, Chinese Patent Document No. ZL202021949710.6 discloses a vehicle-mounted refrigerator, which includes: a housing, the housing includes a refrigerated space and a working space, and the working space includes a first working space and a second working space; a refrigeration system for cooling the interior of the refrigerated box, at least part of the refrigeration system is arranged in the first working space for heat dissipation; a battery assembly arranged in the second working space, the battery assembly includes a battery and a battery installation box, and the battery is detachably installed in the battery installation box; a control system electrically connected to the refrigeration system and the battery. Another example is Chinese Patent Document No. ZL202010998864.2, which discloses a vertical vehicle-mounted refrigerator, and a circuit board box is installed on the upper end surface of the compressor. Content of the Utility Model

[0003] The purpose of the utility model is to provide a protection structure for a control box of a new energy vehicle-mounted refrigerator. By externally installing the control box on the outer side of the main body of the vehicle-mounted refrigerator, the installation space inside the main body of the vehicle-mounted refrigerator can be saved, and it is convenient for later maintenance of the control box. The circuit board in the control box can be maintained without opening the engine compartment of the compressor, and the maintenance is convenient.

[0004] The purpose of the utility model is realized as follows:

[0005] A protection structure for a control box of a new energy vehicle-mounted refrigerator includes a limiting member for limiting and fixing the control box on the main body of the vehicle-mounted refrigerator. The control box is fixed on the main body of the vehicle-mounted refrigerator, and the limiting member is provided with a limiting portion. One side of the control box is limited on the limiting portion of the limiting member. The control box is limited and fixed on the outer side of the main body of the vehicle-mounted refrigerator up and down, front and back, and / or left and right through the limiting portion. The limiting member forms a protection structure for the control box, avoiding the phenomenon that the control box moves up and down, left and right, and back and forth during vehicle operation, and preventing the control box from falling out of the main body of the vehicle-mounted refrigerator.

[0006] The limiting member limits a part of one side of the control box, and the main body of the control box is exposed outside the limiting member, so as to form an open port for assisting the control box to dissipate heat between the main body of the vehicle-mounted refrigerator and the limiting member. The heat generated by the operation of the control box is transmitted outward through the open port, which is convenient for the heat dissipation of the control box, effectively prolongs the service life of the electronic components inside the control box, and further prolongs the service life of the vehicle-mounted refrigerator.

[0007] The control box and the limiting member are detachably installed on the bottom of the main body of the vehicle-mounted refrigerator through the same or different fixing parts respectively;

[0008] When the control box and the limiting member are detachably installed on the bottom of the main body of the vehicle-mounted refrigerator through the same fixing part, fasteners for fixing the control box and the limiting member can be saved on the main body of the vehicle-mounted refrigerator, reducing the production cost.

[0009] Alternatively, the limiting member is detachably installed on the control box. When the limiting member is installed on the control box, the two are assembled into an installation module that is commonly installed and fixed on the bottom of the main body of the vehicle-mounted refrigerator. The limiting member can be first assembled with the control box into an installation module, and then the installation module is fixedly installed on the bottom of the refrigerator main body to achieve modular assembly, effectively improving the assembly efficiency.

[0010] A first fixing part is provided between the bottom of the main body of the vehicle-mounted refrigerator and the control box. The control box is fixed on the main body of the vehicle-mounted refrigerator through the first fixing part, and the limiting member is provided with a clearance opening corresponding to the first fixing part.

[0011] A second fixing part is provided between the bottom of the main body of the vehicle-mounted refrigerator and the limiting member. The main body of the vehicle-mounted refrigerator is fixed on the main body of the vehicle-mounted refrigerator through the second fixing part.

[0012] The control box is installed on the outside of the bottom of the main body of the vehicle-mounted refrigerator. The limiting part includes a first limiting block and / or a second limiting block extending upward along the bottom of the main body of the vehicle-mounted refrigerator. The control box is limited left and right between the first limiting block and the second limiting block.

[0013] The limiting part further includes a third limiting block extending upward along the bottom of the main body of the vehicle-mounted refrigerator. There are two limiting members arranged at intervals in the front and rear on the bottom of the main body of the vehicle-mounted refrigerator. The control box is limited front and rear between the third limiting blocks of the two limiting members.

[0014] The limiting part further includes a fourth limiting block. The control box is installed on the outside of the bottom of the main body of the vehicle-mounted refrigerator and supported on the fourth limiting block. The control box is limited up and down between the bottom of the main body of the vehicle-mounted refrigerator and the fourth limiting block of the limiting member.

[0015] The main body of the vehicle-mounted refrigerator is provided with a first positioning post for cooperatively fixing the control box, and / or the main body of the vehicle-mounted refrigerator is provided with a second positioning post for cooperatively fixing the limiting member.

[0016] Reinforcing ribs for increasing mechanical strength are provided on the outer surface of the first positioning post and / or the second positioning post, improving the fixing strength between the fixing limiting member and the control box.

[0017] The beneficial effects of the present utility model are as follows:

[0018] By externally mounting the control box on the outer side of the vehicle-mounted refrigerator main body, the installation space inside the vehicle-mounted refrigerator main body can be saved, and it is convenient to repair the control box later. The circuit board inside the control box can be repaired without opening the engine compartment of the compressor, which is convenient for maintenance; the control box is installed on the vehicle-mounted refrigerator main body through two limiting members in the up-and-down, front-and-back, and left-and-right directions. The two limiting members form a protection structure for the control box, preventing the control box from moving up and down, left and right, and front and back when the vehicle is running.

[0019] The two limiting members partially cover the outer part of the control box, while the main body of the control box is exposed between the two limiting members, forming an open mouth for assisting the control box to dissipate heat between the vehicle-mounted refrigerator main body and the two limiting members. The heat generated by the operation of the control box is transferred out through the open mouth, facilitating the heat dissipation of the control box, effectively extending the service life of the internal electronic components of the control box, and further extending the service life of the vehicle-mounted refrigerator.
