Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle battery technology, and in particular to a special base support device for new energy vehicle battery boxes. Background Technology

[0002] Currently, new energy vehicle batteries are typically fixed to the vehicle chassis using a base bracket. Traditional base brackets often employ a simple frame structure secured with bolts. However, during vehicle operation, the battery continuously endures vibration and impact loads from various conditions such as road bumps, rapid acceleration, and sudden braking. Existing fixing methods have several limitations: Firstly, the lateral and longitudinal fastening structures of traditional base brackets lack sufficient flexibility for adjustment, making it difficult to adapt to battery bodies of different sizes. This can lead to loosening or excessive compression during installation, potentially causing damage to the battery casing or detachment of internal cells over time. Secondly, the fastening mechanism is not very convenient to operate, requiring various tools for installation and removal, significantly reducing the efficiency of battery maintenance and replacement.

[0003] Therefore, this application provides a dedicated base support device for new energy vehicle battery boxes to meet the requirements. Utility Model Content

[0035] like Figure 1 , Figure 2 and Figure 3 The present invention provides a special base support device for a battery box of a new energy vehicle, which includes a battery body 1, a base 2 mounted on the bottom of the battery body 1, a sliding clamping mechanism 3 for horizontally clamping the battery body 1 on the four corner side walls of the base 2, and a fastening mechanism 4 for vertically fastening the battery body 1 at the middle position on both sides of the base 2.

[0036] The sliding clamping mechanism 3 includes a transverse adjustment groove 301, a threaded drive block 302, a bidirectional lead screw 305, a lateral clamping plate 304, a manual handle 306, a return spring 307, and a rotating shaft 309. The base 2 has transverse adjustment grooves 301 at its four corners. A bidirectional lead screw 305 passes through the transverse adjustment groove 301. One end of the bidirectional lead screw 305 is rotatably connected to the side wall of the transverse adjustment groove 301 via a bearing ring 303, and the other end passes through the side wall of the transverse adjustment groove 301 and connects to the manual handle 306. A circular plate 308 is fitted onto the outer wall of the manual handle 306, and a rotating shaft 309 is fixed to the top of the manual handle 306. A return spring 307 is fitted onto the outer surface of the manual handle 306, and both ends of the return spring 307 are connected to the rotating shaft 309. 9 is connected to the circular plate 308. The outer wall of the bidirectional lead screw 305 is fitted with a threaded drive block 302 that is threadedly engaged with it. One side wall of the threaded drive block 302 is fixedly connected to a lateral clamping plate 304 for abutting against the battery body 1. The inner ends of the four lateral clamping plates 304 abut against the side wall of the battery body 1. The bearing ring 303 is fixed to the side wall of the transverse adjustment groove 301. The circular plate 308 is located at the connection between the outer wall of the base 2 and the manual handle 306. The inner cavity of the threaded drive block 302 is provided with a meshing hole. The bidirectional lead screw 305 drives the threaded drive block 302 to move along the transverse adjustment groove 301 through the meshing hole. The clamping surface of the lateral clamping plate 304 is provided with a wavy elastic rubber layer 310. The surface of the rubber layer 310 is provided with anti-slip texture.

[0037] Specifically, efficient transmission is achieved through the threaded engagement of the bidirectional lead screw 305 and the threaded drive block 302. When the bidirectional lead screw 305 rotates within the lateral adjustment groove 301, the threaded drive blocks 302 on both sides can move synchronously in opposite directions, causing the lateral clamping plate 304 to precisely fit against the four corner sidewalls of the battery body 1. This design ensures that the battery is subjected to uniform force in the lateral direction. The wavy elastic rubber layer 310 at the inner end of the lateral clamping plate 304 plays a crucial role. The rubber material itself has good elastic deformation capability. When the battery is subjected to lateral impact force, the rubber layer 310 can absorb part of the impact force through its own deformation, reducing the damage to the battery sidewalls caused by rigid collisions. The wave-shaped structure and surface anti-slip texture further increase the friction of the clamping surface, enhancing the lateral fixing effect while preventing relative sliding between the side clamping plate 304 and the battery sidewall during clamping. The bidirectional lead screw 305 can be driven to rotate by rotating the manual handle 306, realizing the opening and closing adjustment of the side clamping plate 304. The operation is simple and labor-saving, and the installation and removal of the battery can be completed without complicated tools. The reset spring 307 ensures that the position of the manual handle 306 is locked after adjustment, preventing the lead screw from loosening due to vibration during use.

[0038] In this embodiment, as Figure 4As shown; the fastening mechanism 4 includes an end fixing plate 401, a longitudinal pressing plate 406, and a fixing rod 403. The end fixing plate 401 is fixedly connected to the middle of both ends of the base 2. The longitudinal pressing plate 406 is provided on the inner side of the end fixing plate 401. A threaded hole 402 is provided between the longitudinal pressing plate 406 and the end fixing plate 401. The fixing rod 403 is threadedly connected to the threaded hole 402 through a first external thread 404, and the top of the fixing rod 403 is fixedly connected to the end fixing plate 401. The first external thread 404 is adapted to the threaded hole 402. The bottom of the longitudinal pressing plate 406 is connected to the upper end of the base 2. The battery body 1 has two side walls that abut against the side walls of the longitudinal clamping plate 406. The fastening mechanism 4 also includes a top pressure plate 408 and a nut 407. The fixing rod 403 is L-shaped and has a second external thread 405 on its top outer wall. The top pressure plate 408 with threaded holes at both ends is provided on the top of the battery body 1. The fixing rod 403 passes through the threaded hole of the top pressure plate 408 and is slidably connected to the nut 407. The bottom of the nut 407 is in contact with the upper end surfaces of both sides of the top pressure plate 408. The top pressure plate 408 is concave and has L-shaped limit blocks 409 fixedly connected to the grooves on both sides of its bottom.

[0039] Specifically, the end fixing plate 401 provides support for the entire mechanism. The fixing rod 403 is threadedly connected to the threaded hole 402 of the longitudinal pressing plate 406 via the first external thread 404. By adjusting the fixing rod 403, the operator can drive the longitudinal pressing plate 406 to slide along the upper surface of the base 2 until its side wall is in close contact with the side walls of the battery body 1. This effectively counteracts the longitudinal movement of the battery caused by inertia during vehicle operation, preventing the battery from shifting or colliding in the longitudinal direction and ensuring precise locking of the battery in the longitudinal position. The L-shaped fixing rod 403 The second external thread 405 at the top engages with the nut 407 and the top pressure plate 408 to achieve vertical clamping. The top pressure plate 408 spans above the battery body 1. The vertical height of the top pressure plate 408 can be adjusted by turning the nut 407, so that its bottom is tightly attached to the top surface of the battery, forming a vertical pressure from top to bottom, which further enhances the fit between the battery and the base 2 and the longitudinal clamping plate 406. The L-shaped limiting blocks 409 on both sides of the concave top pressure plate 408 can assist in limiting the top edge of the battery to prevent the battery from shifting laterally during vertical shaking.

[0040] In this embodiment, as Figure 5 As shown; rubber damping buffer posts 5 with a height of 15-20mm are fixedly connected to the four corners of the bottom of the base 2. The buffer posts 5 are embedded with helical damping springs 6. The two ends of the springs 6 are respectively connected to the bottom of the base 2 and the bottom of the buffer posts 5 with metal pads 7. The metal pads 7 are in direct contact with the car chassis.

[0041] Specifically, the rubber damping buffer column 5, the helical damping spring 6, and the metal washer 7 form the bottom buffer structure of the base. The height limitation of the rubber damping buffer column 5 can reserve sufficient buffer space between the base 2 and the car chassis. The helical damping spring 6 is embedded in the buffer column 5, and its two ends are connected to the bottom of the base 2 and the metal washer 7 at the bottom of the buffer column 5, respectively. This design allows the shock absorption force of the spring to act directly between the base and the chassis, while reducing the wear caused by friction.

[0042] Working principle: First, the battery body 1 is placed stably on the upper surface of the base 2. Then, it is laterally clamped by the sliding clamping mechanism 3. Rotating the manual handles 306 at the four corners of the base 1 drives the bidirectional lead screw 305 in the lateral adjustment groove 304 to rotate, causing the threaded drive block 302 to move laterally along the adjustment groove 304, thereby pushing the side clamping plates 304 to move synchronously until the wavy elastic rubber layer 310 of the four side clamping plates 304 is in close contact with the four corner side walls of the battery. At this time, the return spring 307 is compressed to generate a rebound force, forming a pre-tightening to prevent the lead screw from loosening, and the anti-slip texture of the rubber layer 310 enhances friction to prevent slippage.

[0043] Next, the longitudinal and top fixation is completed by the fastening mechanism 4. The longitudinal pressure plate 406 is adjusted, and the first external thread 404 of the fixing rod 403 is engaged with the threaded hole 402 to make the longitudinal pressure plate 406 slide along the base 2 and abut against the two side walls of the battery to achieve longitudinal fastening. Then, the concave top pressure plate 408 is placed above the battery, and the top of the fixing rod 403 passes through the threaded hole 402 of the pressure plate. The nut 407 is tightened to make the pressure plate press against the top of the battery. The L-shaped limit block 409 engages the edge to enhance positioning.

[0044] When the vehicle is in motion, the rubber damping buffer post 5 at the bottom of the base 2 works together with the internal helical damping spring 6 to absorb vibration energy through elastic deformation, and transmit it through the metal pad 7 to reduce the impact on the battery, thus achieving stable clamping and safety protection.
