Technical Field

[0001] This utility model relates to the field of battery swapping technology for new energy vehicles, and in particular to an unlocking and clamping device. Background Technology

[0002] In today's automotive industry, new energy vehicles are experiencing rapid development, gradually showing a trend of replacing traditional fuel vehicles. However, the development of new energy vehicles is still limited by several factors, one of the most prominent being insufficient driving range. To address this challenge, the mainstream solutions currently focus on two main directions: firstly, overcoming battery performance bottlenecks through technological research and development to improve battery capacity and charging speed; secondly, promoting battery swapping services for new energy vehicles to quickly restore their driving range. Currently, the removal of battery packs from new energy vehicles primarily uses manual unlocking. The battery pack unlocking and clamping device is a mechanical component specifically designed for rapid installation and removal, widely used in scenarios requiring frequent opening and closing. This device typically includes one or more battery bolts, which achieve locking and unlocking functions through rotation or pushing.

[0003] The existing BAYOBOLT device for disassembling battery packs of new energy vehicles has several drawbacks during use. These include a limited field of vision when unlocking the BAYOBOLT, the ease with which operations can be missed when pressing the BAYOBOLT to unlock, and difficulty in quickly locating the BAYOBOLT during unlocking, resulting in a long operation time. To address these shortcomings, this application proposes an unlocking and pressing device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an unlocking and clamping device to solve the problems in the background technology, such as the limited field of vision when unlocking BAYOBOLT, the easy omission of operations when unlocking and clamping BAYOBOLT, and the difficulty in quickly positioning BAYOBOLT when unlocking, resulting in a long operation time.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a base plate, a connecting plate fixedly mounted on the top of the base plate, a slide rail fixedly mounted on the right half of the top of the connecting plate, a connecting seat fixedly mounted on the sliding block of the slide rail, a rotatable connecting rod inserted through the side of the connecting seat, a rod groove formed at one end of the connecting rod penetrating the connecting seat, a screw relief seat movably inserted into the rod groove, a sleeve slidably inserted into the screw groove at the end of the screw relief seat, a screw top member movably inserted into the sleeve, a protective sleeve fitted around the outside of the end of the connecting rod penetrating the connecting seat, a manual fixing elbow clamp fixedly mounted on the left half of the top of the connecting plate, an L-shaped welding seat connected to the end of the manual fixing elbow clamp, and the end of the welding seat away from the manual fixing elbow clamp fixedly connected to the side of the connecting seat.

[0006] Optionally, a second groove is provided at one end of the screw relief seat near the connecting seat, and a compression spring is fixedly connected between the first groove at one end of the connecting rod and the second groove at one end of the screw relief seat. A spring is also fixedly connected between the screw top part and the inner wall of the sleeve.

[0007] Optionally, the side of the connector has an opening in which two bearings are fixedly installed. The connecting rod is inserted between the inner rings of the two bearings, and a retaining ring is slidably sleeved at the end of the connecting rod away from the sleeve.

[0008] Optionally, the side wall of the manual elbow clamp end is provided with an annular movable groove, and the end of the welding seat connected to the manual elbow clamp is provided with a retaining groove, and the retaining groove at one end of the welding seat is movably engaged in the movable groove at the end of the manual elbow clamp. A reinforcing plate is welded between the corners of the inner wall of the welding seat.

[0009] Optionally, a gasket is fixedly installed between the top of the sliding block in the slide rail and the bottom of the connecting seat.

[0010] Optionally, connectors are fixedly installed at the four corners of the bottom of the substrate. Screw holes are provided on the sides of the four connectors. A leveling bolt is threaded into each screw hole, and a nut is threaded onto each leveling bolt.

[0011] The beneficial effects of this utility model are:

[0012] By manually operating the elbow clamp, the BAYOBOLT sleeve in the mechanism can be smoothly positioned at the BAYOBOLT, making it convenient for workers to use an electric tightening gun to unlock and tighten the BAYOBOLT. The entire operation is simple and convenient, which not only reduces the failure rate of unlocking and tightening the BAYOBOLT during vehicle battery swapping, but also saves the unlocking and tightening time of the BAYOBOLT during vehicle battery swapping, thus improving the efficiency of manual battery swapping for new energy vehicles.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-4This utility model provides a technical solution: It includes a base plate 10, a connecting plate 2 fixedly mounted on the top of the base plate 10, a slide rail 12 fixedly mounted on the right half of the top of the connecting plate 2, a connecting seat 3 fixedly mounted on the sliding block of the slide rail 12, a rotatable connecting rod 5 inserted through the side of the connecting seat 3, a rod groove opened at one end of the connecting rod 5 passing through the connecting seat 3, a screw relief seat 9 movably inserted into the rod groove, a sleeve 7 slidably inserted into the screw groove at the end of the screw relief seat 9, a screw top member 8 movably inserted into the sleeve 7, a protective sleeve 6 sleeved on the outside of the end of the connecting rod 5 passing through the connecting seat 3, and the left half of the top of the connecting plate 2... A manual fixing elbow clamp 11 is fixedly installed. An L-shaped welding seat 4 is connected to the end of the manual fixing elbow clamp 11. The end of the welding seat 4 away from the manual fixing elbow clamp 11 is fixedly connected to the side of the connecting seat 3. When using this device, the manual fixing elbow clamp 11 is manually moved so that one end moves the welding seat 4, thereby moving the connecting seat 3 on the slide rail 12. This allows the screw release seat 9 at one end of the connecting rod 5 and the sleeve 7 at the end to be properly positioned at the BAYOBOLT. Then, an electric tightening gun is used to unlock and tighten the BAYOBOLT.

[0021] like Figure 2 and Figure 4 As shown, a second groove is provided at one end of the screw relief seat 9 near the connecting seat 3. A compression spring 13 is fixedly connected between the first groove at one end of the connecting rod 5 and the second groove at one end of the screw relief seat 9. A spring 16 is fixedly connected between the screw top part 8 and the inner wall of the sleeve 7. The compression spring 13 can connect one end of the screw relief seat 9 to the first groove at one end of the connecting rod 5. When using an electric tightening gun to unlock and tighten the BAYOBOLT, the compression and extension of the compression spring 13 can cause one end of the screw relief seat 9 to retract and move in the first groove. The spring 16 can connect the screw top part 8 inside the sleeve 7. The spring 16 can buffer and reset the screw top part 8.

[0022] like Figure 2 and Figure 4 As shown, the side of the connecting seat 3 has an opening, in which two bearings 15 are fixedly installed. The connecting rod 5 is inserted between the inner rings of the two bearings 15. A retaining ring 14 is slidably sleeved at the end of the connecting rod 5 away from the sleeve. The position of the connecting rod 5 can be fixed by the two bearings 15, so that the connecting rod 5 can rotate stably between the connecting seats 3. The retaining ring 14 can restrict the connecting rod 5 in the axial direction to prevent loosening or falling off due to vibration or other external forces.

[0023] like Figure 1 and Figure 3As shown, the side wall of the end of the manual elbow clamp 11 is provided with an annular movable groove. The end of the welding seat 4 connected to the manual elbow clamp 11 is provided with a slot, and the slot of the welding seat 4 is movably engaged in the movable groove of the end of the manual elbow clamp 11. A reinforcing plate is welded between the corners of the inner wall of the welding seat 4. In this way, a certain range of motion will be left between the end of the welding seat 4 and the end of the manual elbow clamp 11, so as to avoid the connection between the manual elbow clamp 11 and the welding seat 4 being too tight.

[0024] like Figure 3 As shown, a shim 17 is fixedly installed between the top of the sliding block in the slide rail 12 and the bottom of the connecting seat 3. When the BAYOBOLT is unlocked and tightened using an electric tightening gun, the shim 17 can play a shock-absorbing role between the two.

[0025] like Figure 1 and Figure 2 As shown, connectors 1 are fixedly installed at the four corners of the bottom of the substrate 10. Screw holes are provided on the sides of the four connectors 1. A leveling bolt 18 is threaded into each screw hole, and a nut 19 is threaded onto each leveling bolt 18. The substrate 10 can be horizontally adjusted by the cooperation of the leveling bolt 18 and the nut 19.
