[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] like Figures 1 to 5 As shown, this utility model provides a protective housing for a battery, including a base plate 100. The outer walls of the base plate 100 are movably provided with frame 110. The top of the frame 110 is provided with a top cover 103. The frame 110 is composed of a first frame 111 and a second frame 112. The inner wall of the base plate 100 is provided with a hidden groove 140. Two sets of partition frames 170 are assembled in the hidden groove 140. An inner lining plate 171 is movably sleeved between the two sets of partition frames 170. The outer wall of the base plate 100 is provided with multiple sets of ventilation grooves 160 that communicate with the hidden groove 140.

[0026] Each set of base plates 100 has a T-strip 130 extending into the inner wall of the base plate 100. The T-strip 130 is located near the bottom end of the inner wall of the base plate 100. A circular groove 102 is opened at the center of the top of the base plate 100. An active disk 180 is rotatably installed in the circular groove 102. A spiral bar 120 is fixed at the bottom end of the active disk 180. The bottom end of the spiral bar 120 extends into the top of the four sets of T-strips 130. An arc groove 131 is opened at the contact position between the top of the T-strip 130 and the spiral bar 120.

[0027] The inner walls of the first frame 111 and the second frame 112 are configured with dovetail blocks and T-strips 130 sliding together.

[0028] The battery can be placed on the top of the bottom plate 100 inside the four sets of frames 110, and then the top cover 103 is covered. When different models of batteries are placed, an external force can be applied to the driving disc 180 to make it rotate, and the vortex-shaped strip 120 at the bottom end generates an outward force on the arc groove 131, making the four sets of T-shaped strips 130 move outward, and then the four sets of frames 110 will move away from one side of the bottom plate 100, and the first frame 111 and the second frame 112 will relatively move away along the T-shaped strip 130. The expansion adjustment of the four sets of frames 110 is completed, and then the battery can be placed on the top of the bottom plate 100, so that different models of batteries can be placed;

[0029] The spacer 170 inside the four sets of frames 110 can also be removed, and the size of the battery is placed above the bottom plate 100, so that the space formed by the bottom plate 100 and the frame 110 is divided, thereby ensuring that there is a gap between the placed batteries, and the external air will enter through the ventilation groove 160. In this way, the air flow around the electromagnetic can be accelerated, and the accumulation of heat is avoided to threaten the safety of the battery, and the battery is more secure during transportation.

[0030] Please refer to Figure 2 and Figure 4 , the end surface of the bottom plate 100 is provided with a T-shaped groove 101 at the contact position of each set of T-shaped strips 130, and the T-shaped groove 101 is in communication with the circular groove 102.

[0031] Ensure that the T-shaped strip 130 moves linearly under the assistance of the T-shaped groove 101, and completes the outward expansion or inward gathering of the frame 110.

[0032] Please refer to Figure 3 , the upper and lower inner walls of the hidden groove 140 are fixed with rubber strips 141, and the upper and lower ends of the spacer 170 are provided with recesses 172 matched with the rubber strips 141.

[0033] The deformed characteristic of the rubber strip 141 can ensure that the spacer 170 is stable after entering the hidden groove 140, and realizes the effect of hidden storage.

[0034] Please refer to Figure 3 , the inner wall of the hidden groove 140 near the outside of the frame 110 is equally provided with a plurality of positioning grooves 150, and the size of the positioning groove 150 is equal to the end of the spacer 170.

[0035] The two ends of the spacer 170 placed above the bottom plate 100 are constrained to prevent the situation of deviating to both sides, thereby ensuring the stability of the placed battery.

[0036] Please refer to Figure 2 and Figure 4 , the four sets of end surfaces of the bottom plate 100 are provided with storage grooves above the T-shaped grooves 101, and the driven strip plate 190 fixed with the inner wall of the frame 110 is slidably arranged in the storage groove.

[0037] The gap between the frame 110 and the bottom plate 100 is supplemented by the driven strip plate 190, and the placed battery bottom end is supported.

[0038] Please refer to Figure 5 The first frame 111 and the second frame 112 are provided with frame grooves at one end close to each other, and the connecting plate 113 is movably arranged in the frame grooves.

[0039] The gap between the first frame 111 and the second frame 112 is supplemented, and the placed battery is prevented from being exposed, thereby achieving better protection effect.

[0040] Please refer to Figure 5 The structure of the top cover 103 outwardly expanded to the four directions is the same as the connection of the bottom plate 100 and the four frames 110.

[0041] In use, the battery can be placed on the top of the bottom plate 100 and inside the four frames 110, and then the top cover 103 is covered, when the different models of batteries are placed, the external force is applied to the driving disc 180 to rotate, the vortex-shaped strip 120 at the bottom end of the driving disc 180 generates an outward force on the arc groove 131, the four T-shaped strips 130 move outward, and then the four frames 110 move away from one side of the bottom plate 100, and the first frame 111 and the second frame 112 relatively move away along the T-shaped strip 130, the outward expansion adjustment of the four frames 110 is completed, and then the battery can be placed on the top of the bottom plate 100, and different models of batteries can be placed.

[0042] The partition frame 170 inside the four frames 110 can also be taken out, the size of the battery is placed above the bottom plate 100, the space formed by the bottom plate 100 and the frame 110 is divided, thereby ensuring that there is a gap between the placed batteries, and the external air enters through the ventilation groove 160, so that the air flow around the electromagnetic is accelerated, and the safety of the battery is ensured.
