Technical Field

[0001] The utility model relates to the technical field of battery boxes, and particularly relates to a battery box which is convenient for disassembly and assembly. Background Technique

[0002] A battery box is a box for installing and storing batteries, which plays a role in protecting the batteries, preventing them from being damaged by external impacts and squeezes, etc. Putting the batteries into the battery box cuts off the contact between the batteries and the outside, forming protection for the batteries. At the same time, the design of the battery box should be able to protect the batteries from damage when the vehicle collides, reducing safety risks.

[0003] Most of the existing battery boxes are fixedly connected to the fixing brackets for installing the battery boxes by means of bolts, etc. Since a large number of bolts are used, when disassembling and separating the battery box from the fixing bracket, not only a lot of time is required for disassembling the bolts, but also tools are needed to facilitate the disassembly of the bolts, which easily reduces the disassembly and assembly efficiency of the battery box. To solve this technical problem, the utility model proposes a battery box which is convenient for disassembly and assembly. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a battery box which is convenient for disassembly and assembly, and can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A battery box which is convenient for disassembly and assembly includes a lower housing, an upper housing and a fixing bracket. Two groups of guiding pressing plates are arranged inside the lower housing, and the guiding pressing plates are L-shaped plate-like. A locking buckle is movably arranged between the two groups of guiding pressing plates, and one side of the locking buckle is a slope surface. A return spring is arranged on one side of the locking buckle, and a disassembly button is movably arranged on the slope surface of the locking buckle. A clamping convex frame is arranged at the top end of the fixing bracket, and the locking buckle is movably inserted into the inside of the clamping convex frame.

[0007] Preferably, two groups of limiting shells penetrate through the inside of the lower housing, and a battery body is arranged inside the lower housing.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a battery case that is convenient for disassembly and assembly;

[0023] It includes a lower housing 1, an upper housing 8 and a fixing bracket 13. Two groups of guiding pressing plates 3 are arranged inside the lower housing 1, and the guiding pressing plates 3 are L-shaped plate-like. A locking buckle 4 is movably arranged between the two groups of guiding pressing plates 3, and one side of the locking buckle 4 is a slope surface. A return spring 5 is arranged on one side of the locking buckle 4. A disassembly button 6 is movably arranged on the slope surface of the locking buckle 4. A clamping convex frame 14 is arranged at the top of the fixing bracket 13, and the locking buckle 4 is movably inserted into the inside of the clamping convex frame 14.

[0024] The guiding pressing plates 3 arranged inside the lower housing 1 are positioned inside the lower housing 1 by bolts. The locking buckle 4 is movably limited between the two groups of guiding pressing plates 3. The two groups of "L"-shaped guiding pressing plates 3 can linearly limit the movement of the locking buckle 4. Since the slope surface of the locking buckle 4 contacts the slope surface of the disassembly button 6, when a downward pressure is applied to the disassembly button 6, the disassembly button 6 is pressed to drive the locking buckle 4 to move outwards, so that the locking buckle 4 is separated from the clamping convex frame 14 at the top of the fixing bracket 13, thereby separating the lower housing 1 from the fixing bracket 13, realizing the disassembly of the fixing bracket 13 and the lower housing 1. The structure is simple and practical, without the need to use external tools, effectively improving the disassembly efficiency of the battery case;

[0025] When the lower housing 1 is pressed downwards, the clamping convex frame 14 at the top of the fixing bracket 13 is inserted into the limiting shell 2. The clamping convex frame 14 can drive the locking buckle 4 to move to the right. When it is closed, the locking buckle 4 moves under the elastic force of the return spring 5, and the locking buckle 4 is used to insert into the clamping convex frame 14 to fasten the fixing bracket 13, thereby realizing the locking state of the fixing bracket 13 and the lower housing 1.

[0026] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a battery case that is convenient for disassembly and assembly;

[0027] Two groups of limiting shells 2 are penetrated and arranged inside the lower housing 1. A battery body 7 is arranged inside the lower housing 1. The upper housing 8 is detachably arranged at the top of the lower housing 1. A limiting cylinder 9 is penetrated and arranged inside the upper housing 8. The disassembly button 6 is movably located inside the limiting cylinder 9. A charging interface 10 is arranged inside the lower housing 1. A battery male-female interface 11 is arranged inside the lower housing 1. The fixing bracket 13 is detachably arranged at the bottom of the lower housing 1. The clamping convex frame 14 is movably inserted into the inside of the limiting shell 2. A power switch 12 is arranged inside the upper housing 8. The other end of the return spring 5 contacts the inner side of the lower housing 1.

[0028] The lower housing 1 and the upper housing 8 are the main combined components of the battery box. After the lower housing 1 and the upper housing 8 are combined, they can cover and protect components such as the battery body 7, the charging interface 10, and the battery male and female interfaces 11. The limiting cylinder 9 provided inside the upper housing 8 is used to limit and block the upward distance of the disassembly button 6, and the limiting cylinder 9 can be used to limit and assist the up and down movement of the disassembly button 6 at a suitable distance. The charging interface 10 inside the battery box is used to connect to an external charger, which allows current to be transmitted from the charger to the inside of the battery box to charge the battery. This interface is the connection point between the battery management system (BMS) and the external power supply to ensure that the battery can be charged safely and effectively. The battery male and female interfaces 11 refer to the interfaces inside the battery box for connecting between battery cells. These interfaces may be for realizing the series or parallel connection of battery cells to achieve the required voltage and capacity. The battery male and female interfaces 11 ensure that the battery cells can be correctly connected and provide mechanical fixation and electrical connection during battery assembly. The power switch 12 can be used to control the power-on operation of the battery inside the battery box.

[0029] During use, the two "L"-shaped guiding pressing plates 3 are used to linearly limit the movement of the lock 4. Since the inclined surface of the lock 4 contacts the inclined surface of the disassembly button 6, when a downward pressure is applied to the disassembly button 6, the disassembly button 6 is pressed to drive the lock 4 to move outward, so that the lock 4 is disengaged from the clamping convex frame 14 at the top of the fixed bracket 13, thereby disengaging the lower housing 1 from the fixed bracket 13 and realizing the disassembly of the fixed bracket 13 from the lower housing 1. The structure is simple and practical, without the need for external tools, effectively improving the disassembly efficiency of the battery box;

[0030] When the lower housing 1 is pressed downward, the clamping convex frame 14 at the top of the fixed bracket 13 is inserted into the limiting shell 2. The clamping convex frame 14 can be used to drive the lock 4 to move to the right. When it is closed, the lock 4 moves under the elastic force of the return spring 5, and the lock 4 is used to insert into the clamping convex frame 14 to latch the fixed bracket 13, thereby realizing the locking state of the fixed bracket 13 and the lower housing 1.
