DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] In one embodiment, Figure 1-Figure 6 As shown, a small lithium battery that is easy to disassemble and assemble includes a lithium battery housing 101, a battery compartment 102 is provided on the outside of the lithium battery housing 101, a handle 104 is provided on the top of the lithium battery housing 101, a waterproof ring 105 is concentrically provided at the line outlet on the top of the lithium battery housing 101, an electric wire 106 is passed through the waterproof ring 105, and a plug 107 is connected to the end of the electric wire 106.

[0027] In this embodiment, a mounting base 103 is provided on the top of the battery compartment 102, and the battery compartment 102 is threadedly connected to a cross screw 108. The mounting base 103 is fixed to the battery compartment 102 by the cross screw 108. A self-locking mechanism is provided on the mounting base 103. When the lithium battery casing 101 is installed, the lithium battery casing 101 is directly placed into the battery compartment 102. The self-locking mechanism automatically locks the lithium battery casing 101 without manual operation. When disassembling the lithium battery casing 101, it only needs to be unlocked first, and the lithium battery casing 101 can be smoothly taken out.

[0028] In one embodiment, Figure 2 and Figure 5As shown, the self-locking mechanism includes a telescopic bin 206 arranged in the mounting seat 103, a stopper 205 is arranged at the left end of the telescopic bin 206, and the right end of the telescopic bin 206 is connected to the telescopic bin cover 207. A spring 202 is arranged in the telescopic bin 206, and the right end of the spring 202 contacts the left side of the telescopic bin cover 207, and the left end of the spring 202 contacts the right side of the boss 208. The left side of the boss 208 is connected to the telescopic locking block 201, and the upper end surface of the boss 208 is connected to the fixed column 204. A slide groove 203 is arranged on the mounting seat 103 on the moving path of the fixed column 204, and the fixed column 204 passes through The slide groove 203 is slidably connected to the quick unlocking unit. In the initial state, the boss 208 is restricted by the block 205 inside the telescopic compartment 206, and the spring 202 presses against the boss 208 to expose the telescopic lock block 201 outside the telescopic compartment 206. When the lithium battery housing 101 is installed, the arc surface at the left end of the telescopic lock block 201 converts the downward pressure of the bottom of the lithium battery housing 101 into a force for the telescopic lock block 201 to retract toward the telescopic compartment 206. The telescopic lock block 201 retracts toward the inside of the telescopic compartment 206. After the lithium battery housing 101 drops into place, the telescopic lock block 201 pops out again under the action of the spring 202 to lock the lithium battery housing 101.

[0029] In one embodiment, Figure 1-Figure 3 As shown, the quick unlocking unit includes a first limit block 209 and a second limit block 211 connected to one side of the upper surface of the mounting seat 103, the first limit block 209 is provided with a first limit groove 210, the second limit block 211 is provided with a second limit groove 212, the first limit groove 210 and the second limit groove 212 are slidably connected to the same linkage rod 213, the linkage rod 213 is connected with a fixing block 214, the fixing block 214 is in sliding contact with the fixing column 204, when disassembling the lithium battery shell 101, the linkage rod 213 is allowed to slide in the first limit groove 210 and the second limit groove 212, the linkage rod 213 drives the fixing block 214 to slide, the fixing block 214 acts on the fixing column 204 to make the fixing column 204 move along the slide groove 203, the fixing column 204 drives the telescopic lock block 201 to retract into the telescopic bin 206 through the boss 208 and compress the spring 202, at this time the self-locking mechanism is in an unlocked state, and the lithium battery shell 101 can be directly taken out.

[0030] In one embodiment, Figure 1 As shown, the linkage rod 213 is connected with a push plate 216, so that the operator can unlock the door more conveniently and with less effort.

[0031] In one embodiment, Figure 2As shown, a positioning groove 215 is provided on the fixing block 214. In the unlocked state, the fixing column 204 is located at the position of the positioning groove 215. Due to the elastic force of the spring 202, the fixing column 204 and the fixing block 214 are tightly combined at the positioning groove 215 to prevent the telescopic locking block 201 from being accidentally ejected due to vibration, so that the self-locking mechanism can be more stably in the unlocked state, which is convenient for the operator to smoothly remove the lithium battery casing 101.

[0032] In one embodiment, Figure 5 As shown, the spring 202 is in the shape of a square spiral. The square spiral spring 202 is less likely to tilt inside the telescopic compartment cover 207, thereby improving the stability of the self-locking mechanism.

[0033] In one embodiment, Figure 6 As shown, the outer wall of the lithium battery housing 101 is provided with a spring 301, and the bottom of the lithium battery housing 101 is connected to a shock-absorbing gasket 302 to reduce the shaking of the lithium battery housing 101 inside the battery compartment 102, protect the lithium battery housing 101, and reduce the failure rate.

[0034] Example 2

[0035] In one embodiment, Figure 1 As shown, a handle base 304 is provided at the lower end of the handle 104 to increase the contact area between the handle 104 and the lithium battery housing 101, disperse the force, and protect the shell of the lithium battery housing 101. A protective pad 303 is provided at the top of the lithium battery housing 101 at a position corresponding to the telescopic lock block 201. During actual use, when the lithium battery housing 101 is affected by the outside world and is about to shift relative to the battery compartment 102, the telescopic lock block 201 will generate a large force on the lithium battery housing 101 to limit its displacement. Since the contact surface between the telescopic lock block 201 and the lithium battery housing 101 is small, there is a risk of damage to the shell of the lithium battery housing 101 when the telescopic lock block 201 directly contacts the lithium battery housing 101. Adding a protective pad 303 with a large surface area between the lithium battery housing 101 and the telescopic lock block 201 can disperse the force from the telescopic lock block 201, protect the shell of the lithium battery housing 101, and prevent damage.

[0036] The above embodiment discloses a small lithium battery that is easy to disassemble and assemble, wherein in the initial state, the boss 208 is restricted by the block 205 inside the telescopic compartment 206, and the spring 202 presses against the boss 208 to expose the telescopic lock block 201 outside the telescopic compartment 206. When the lithium battery shell 101 is installed, the arc surface at the left end of the telescopic lock block 201 converts the downward pressure of the bottom of the lithium battery shell 101 into a force for the telescopic lock block 201 to retract into the telescopic compartment 206, and the telescopic lock block 201 retracts into the telescopic compartment 206. After the lithium battery shell 101 is installed in place, the telescopic lock block 201 pops up again under the action of the spring 202, locking the lithium battery When disassembling the lithium battery housing 101, the push plate 216 is pushed to allow the linkage rod 213 to slide in the first limiting groove 210 and the second limiting groove 212, and the linkage rod 213 drives the fixed block 214 to slide, and the fixed block 214 acts on the fixed column 204 to make the fixed column 204 move along the slide groove 203, and the fixed column 204 drives the telescopic lock block 201 to retract into the telescopic bin 206 through the boss 208 and compress the spring 202. At this time, the upper end of the fixed column 204 is tightly combined with the positioning groove 215 to prevent the telescopic lock block 201 from being accidentally ejected due to vibration, and then the lithium battery housing 101 can be directly taken out.

[0037] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
