Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figure 1-3 The present invention provides a technical solution: a protective shell for a lead-acid battery, comprising a base plate 1 and a protective shell 13 with an open bottom end;

[0021] Both sides of the upper surface of the base plate 1 are provided with transverse grooves 2 along their length direction. The interior of each transverse groove 2 is slidably connected with a sliding seat 5 along the width direction of the base plate 1. The rear end of the upper surface of each sliding seat 5 is fixedly connected with an L-shaped first limiting piece 7. The front end of each sliding seat 5 is fixedly connected with an L-shaped second limiting piece 8. The front end surface of each second limiting piece 8 is provided with a horizontally through mounting opening. The interior of each mounting opening is horizontally fixedly connected with a threaded sleeve 9. The interior of each threaded sleeve 9 is horizontally threadedly connected with a threaded rod 10. The rear end of each threaded rod 10 is rotatably connected with a sliding piece 11. The two sliding pieces 11 are respectively slidably connected to the inner surface of the two second limiting pieces 8.

[0022] The protective housing 13 is detachably mounted on the upper surface of the base plate 1.

[0023] In this embodiment, the sliding seats 5 in the two transverse grooves 2 of the device can be adjusted to change the distance between them. After the lead-acid battery is placed on the upper surface of the placement base plate 1 of the device, the two sliding seats 5 are adjusted to move closer to each other until the first limiting piece 7 at the rear end of the two sliding seats clamps and fixes the lead-acid battery. Then, the two front threaded rods 10 can be rotated. Under the action of the threaded sleeve 9, the threaded rods 10 will move laterally, and the sliding pieces 11 at their rear ends will move synchronously until the two sliding pieces 11 are tightly attached to the outer surface of the lead-acid battery, thereby clamping and fixing the lead-acid battery.

[0024] After the lead-acid battery is clamped and fixed, it is firmly fixed on the base plate 1 of the device. When the device is impacted, the lead-acid battery will not come into contact with any hard object because it is completely fixed, and will not be damaged due to the collision, thus avoiding leakage of electrolyte.

[0025] This structure allows the device to be adapted to various sizes of lead-acid batteries, improving its versatility.

[0026] Furthermore, a connecting hole is provided transversely between the two transverse grooves 2, and a bidirectional lead screw 3 is rotatably connected to the inside of the connecting hole. Both ends of the bidirectional lead screw 3 are threaded with lead screw sleeves 4. One side surface of each of the two sliding seats 5 is provided with a mounting hole that matches the lead screw sleeve 4. The two sliding seats 5 are fixedly connected to the two lead screw sleeves 4 through the mounting holes on them respectively.

[0027] In this embodiment, one end of the bidirectional lead screw 3 is rotatably inserted through one side surface of the base plate 1 and extends outward. A cross groove is provided on the outer surface of this end of the bidirectional lead screw 3. People can drive the bidirectional lead screw 3 to rotate by inserting a screw rod into the cross groove and rotating it. During the rotation of the bidirectional lead screw 3, the lead screw sleeves 4 on both ends of its surface will move in opposite directions and the moving distance is exactly the same. In this way, the sliding seats 5, which are fixedly connected to the two lead screw sleeves 4 respectively, can move in opposite directions.

[0028] Furthermore, multiple guide rods 6 are fixedly connected laterally along the width direction inside the two transverse grooves 2, and multiple guide holes are opened laterally through one side surface of the two sliding seats 5, which correspond to and are adapted to the multiple guide rods 6 inside the transverse grooves 2. The two sliding seats 5 are laterally slidably connected to the outer surface of the multiple guide rods 6 through the multiple guide holes.

[0029] In this embodiment, the guide rod 6 is used to guide and limit the sliding seat 5, ensuring that the two sliding seats 5 will only move laterally and will not deviate, thus ensuring the stability of the device in holding the battery.

[0030] Furthermore, a slot 12 that matches the bottom edge contour of the protective shell 13 is provided on the outer edge of the upper surface of the base plate 1. Multiple mounting holes 16 are vertically provided on the upper surface of the base plate 1 outside the slot 12. Multiple mounting pieces 14 corresponding to the multiple mounting holes 16 are fixedly connected to the bottom end of the outer surface of the protective shell 13. The upper surface of each mounting piece 14 is vertically provided with a connecting hole 15. The protective shell 13 is detachably mounted on the upper surface of the base plate 1 through the multiple mounting pieces 14.

[0031] In this embodiment, the protective casing 13 is installed on the placement base plate 1 with screws, and after installation, it can completely wrap around the lead-acid battery body and protect it.

[0032] Furthermore, the interior of the protective housing 13 is provided with a coolant circulation pipe 17.

[0033] In this embodiment, the coolant circulation pipe 17 can be circulated with coolant to continuously cool the space inside the protective casing 13, ensuring that the temperature of the lead-acid battery does not become too high during use.

[0034] Furthermore, a torsion plate is fixedly connected to the front end of each of the two threaded rods 10.

[0035] In this embodiment, the two torsion plates facilitate the rotation of the threaded rod 10.

[0036] The working principle and usage process of this utility model are as follows: After the utility model is installed, the sliding seats 5 in the two transverse grooves 2 of the device can be adjusted to change the distance between them. After placing the lead-acid battery on the upper surface of the placement base plate 1 of the device, adjust the two sliding seats 5 to move closer to each other until the first limiting piece 7 at the rear end of the two sliding seats clamps and fixes the lead-acid battery. Then, rotate the two front threaded rods 10. Under the action of the threaded sleeve 9, the threaded rods 10 will move laterally, and the sliding pieces 11 at their rear ends will move synchronously until the two sliding pieces 11 are tightly attached to the outer surface of the lead-acid battery. In this way, the lead-acid battery can be clamped and fixed. After the lead-acid battery is clamped and fixed as a whole, it is firmly fixed on the placement base plate 1 of the device. When the device is impacted, the lead-acid battery is completely fixed, so its outer surface will not come into contact with any hard object, and it will not be damaged due to collision, thereby avoiding leakage of electrolyte.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
