Description

Technical Field

[0001] This utility model relates to the field of battery swapping cabinets, and in particular to a battery swapping cabinet with multiple charging compartments. Background Technology

[0002] Battery swapping stations are designed with battery replacement as their core function, providing users with a quick way to replace batteries with fully charged ones (such as shared electric vehicles, logistics vehicles, etc.).

[0003] Existing battery swapping cabinets are usually cabinet-type, and direct contact between lithium battery devices and the cabinet can easily lead to heat transfer, which can affect other lithium battery devices or even damage them. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a battery swapping cabinet with multiple charging compartments, which solves the problem that direct contact between lithium battery devices and the compartments can easily lead to heat transfer and damage to other equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery swapping cabinet with multiple charging compartments, including a bracket installed inside the battery swapping cabinet and multiple charging cabinets spaced apart on the bracket, the distance between the upper and lower ends of two longitudinally adjacent charging cabinets is a first spacing, the distance between the left and right side walls of two laterally adjacent charging cabinets is a second spacing, and the first spacing is smaller than the second spacing.

[0006] The charging cabinet has four walls: an upper wall, a lower wall, a left wall, and a right wall. Except for the charging control circuit board on the outer surface of the left or right wall, the other three walls are provided with ventilation parts that communicate with the inner cavity of the charging cabinet. The charging control circuit board is located within the second spacing.

[0007] Furthermore, the length of the first spacing shall not be less than 10 mm.

[0008] Furthermore, the upper surface of the lower end wall is provided with two first protrusions, and the ventilation part is an air hole, which is located at the upper end of the first protrusion and penetrates the lower end wall.

[0009] Furthermore, the inner walls of the left and right sides are each provided with a second protrusion, which is located above the first protrusion, and the first and second protrusions are in the shape of slats.

[0010] Furthermore, the ventilation section on the upper end wall is an opening that penetrates the upper end wall, and a smoke sensor with a detection end corresponding to the inner cavity of the charging cabinet is provided in the opening.

[0011] Furthermore, the ventilation section provided on the left or right side wall consists of multiple rectangular air holes arranged at equal intervals, and the rectangular air holes are located above the second protrusion.

[0012] Furthermore, the lower end wall, left side wall and right side wall are all provided with movable grooves, and the first protrusion and the second protrusion are fastened into the movable grooves by fastening parts.

[0013] Furthermore, the movable groove has two parts: a first groove and a second groove. The first groove is smaller than the second groove, and the second groove is the same size as the fastening part.

[0014] Furthermore, the width of the charging control circuit board is smaller than the second spacing, and the charging control circuit board is connected to the charging cabinet via a connecting post.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, when the battery is placed in the charging cabinet, because multiple charging cabinets are separated by brackets, the heat conduction caused by the direct contact between the battery and the charging cabinet will not be transferred to another charging cabinet. Furthermore, the first longitudinal spacing and the second transverse spacing between two adjacent charging cabinets provide sufficient heat dissipation space for the charging cabinet, further reducing the impact of heat conduction on another charging cabinet or other equipment.

[0022] Explanation of reference numerals in the attached diagram:

[0023] Movable groove 1, first groove body 01 and second groove body 02, fastening part 2;

[0024] 10 brackets, 20 charging cabinets, first spacing a, second spacing b;

[0025] Upper end wall 21, lower end wall 22, left side wall 23, right side wall 24, ventilation section 25, air hole 251, opening 252, rectangular air hole 253, first protrusion 26, second protrusion 27, smoke sensor 28;

[0026] Charging control circuit board 30, connecting post 31. Detailed Implementation

[0027] Please refer to Figure 1-5 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a battery swapping cabinet with multiple charging compartments, including a bracket 10 installed inside the battery swapping cabinet and multiple charging cabinets 20 spaced apart on the bracket 10. The distance between the upper and lower ends of two longitudinally adjacent charging cabinets 20 is a first distance a, and the distance between the left and right side walls of two laterally adjacent charging cabinets 20 is a second distance b. The first distance a is smaller than the second distance b.

[0028] The charging cabinet 20 has four walls: an upper wall 21, a lower wall 22, a left side wall 23, and a right side wall 24. Except for the left side wall 23 or the right side wall 24, which has a charging control circuit board 30 on its outer surface, the other three walls have ventilation sections 25 communicating with the inner cavity of the charging cabinet 20. The charging control circuit board 30 is located within the second spacing b. When the battery is placed inside the charging cabinet 20, because the multiple charging cabinets 20 are separated by brackets 10, heat conduction caused by direct contact between the battery and the charging cabinet 20 will not be transferred to another charging cabinet 20. Furthermore, the first longitudinal spacing a and the second transverse spacing b between two adjacent charging cabinets 20 provide sufficient heat dissipation space, further reducing the impact of heat conduction on other charging cabinets 20 or other equipment. In addition, the ventilation sections 25 on the charging cabinet 20 further enhance the heat dissipation effect on the inner cavity of the charging cabinet 20.

[0029] Specifically, the length of the first spacing a is not less than 10mm. When the first spacing a is not less than 10mm, because the second spacing b is greater than the first spacing a, the second spacing b, on which the charging control circuit board 30 is installed, also has sufficient heat dissipation space, thereby increasing the heat dissipation effect between different charging cabinets 20 and enhancing the safety performance of the battery swapping cabinet.

[0030] For example, the upper surface of the lower end wall 22 is provided with two first protrusions 26, and the vent 25 is an air hole 251. The air hole 251 is located on the upper end of the first protrusions 26 and passes through the lower end wall 22. The two first protrusions 26 are installed parallel to each other on the lower end wall 22, so that after the battery is placed in the charging cabinet 20, it overlaps the first protrusions 26 to reduce the impact of the battery heating on the charging cabinet 20, and the opening of the air hole 251 cools down the battery placed on the first protrusions 26.

[0031] For example, the inner walls of the left side wall 23 and the right side wall 24 are each provided with a second protrusion 27. The second protrusion 27 is located above the first protrusion 26, and the first protrusion 26 and the second protrusion 27 are in the shape of a slat. The second protrusion 27 is consistent with the first protrusion 26. By positioning the second protrusion 27 above the first protrusion 26, the battery placed in the charging cabinet 20 is placed on the first protrusion 26, with its sides overlapping the second protrusion 27, thereby reducing the impact of battery heat conduction on the charging cabinet 20.

[0032] For example, the ventilation section 25 provided on the upper end wall 21 is an opening 252 that penetrates the upper end wall 21. A smoke sensor 28 with its detection end corresponding to the inner cavity of the charging cabinet 20 is provided within the opening 252. Through the opening 252 at the top of the upper end wall 21, when a battery placed inside the charging cabinet 20 malfunctions, smoke rises through the opening 252 and triggers an alarm via the smoke sensor 28. The smoke sensor 28 is model JTY-GD-HA521.

[0033] For example, the ventilation portion 25 provided on the left side wall 23 or the right side wall 24 consists of a plurality of rectangular air holes 253 arranged at equal intervals, and the rectangular air holes 253 are located above the second protrusion 27. The opening of the rectangular air holes 253 can further increase the heat dissipation effect inside the charging cabinet 20.

[0034] For example, the lower end wall 22, the left side wall 23, and the right side wall 24 are all provided with a movable groove 1, and the first protrusion 26 and the second protrusion 27 are fastened into the movable groove 1 by the fastening part 2. Through the cooperation of the movable groove 1 and the fastening part 2, the operator can disassemble the first protrusion 26 and the second protrusion 27 to adapt to different usage scenarios.

[0035] For example, the first protrusion 26 and the second protrusion 27 can be made of heat-insulating and flame-retardant materials. However, heat-insulating and flame-retardant materials have a service life. As the service time increases, the flame-retardant effect of the first protrusion 26 and the second protrusion 27 deteriorates. At this time, it is necessary to replace the first protrusion 26 and the second protrusion 27.

[0036] For example, the movable slot 1 has two parts: a first slot 01 and a second slot 02. The first slot 01 is smaller than the second slot 02, and the second slot 02 is the same size as the fastening part 2. When the fastening part 2 moves into the first slot 01, it can maintain the stability of the first protrusion 26 and the second protrusion 27 installed in the charging cabinet 20. When the fastening part 2 moves into the second slot 02, the first protrusion 26 and the second protrusion 27 can be separated from the charging cabinet 20.

[0037] The width of the charging control circuit board 30 is less than the second spacing b, and the charging control circuit board 30 is connected to the charging cabinet 20 through the connecting post 31.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
