[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0019] Example Reference Figure 1-4 This is an embodiment of the present utility model, which provides a quick-locking clamp for the front box of a new energy vehicle, comprising: The fixing component 100 includes a positioning pin 101, a support frame 102 fixedly connected to the side wall of the positioning pin 101, and a locking block 103 fixedly connected to the side wall of the support frame 102. The locking block 103 is located at the center of the support frame 102. The adjusting assembly 200 includes a clamping post 203 that is snapped onto the side wall of the locking block 103, an auxiliary support tube 202 that is fixedly installed on the side wall of the clamping post 203, and a positioning bolt 201 that is fixedly connected to the side wall of the auxiliary support tube 202. The clamping post 203 is provided with a groove that cooperates with the locking block 103.
[0020] Specifically, the adjustment assembly 200 also includes a ball bearing 204 slidably mounted on the inner wall of the tensioning column 203, a pressure plate 205 sleeved on the outer wall of the ball bearing 204, a limiting block 206 fixedly mounted on the side wall of the pressure plate 205, and a floating pin bracket 207 fixedly mounted on the side wall of the limiting block 206. The end of the floating pin bracket 207 is provided with a shock-absorbing spring 208, and the end of the shock-absorbing spring 208 is fixedly connected to the inner wall of the positioning bolt 201.
[0021] Among them, the tension damping spring 208 absorbs vibration energy through the elastic deformation of the spring, realizes buffering and damping, avoids vibration from being transmitted to fixed components or external reference components, and protects the precision fit structure of the adjustment component.
[0022] Furthermore, the side wall of the support frame 102 is provided with a groove for cooperating with the locking block 103, and the side wall of the support frame 102 is provided with a thread for cooperating with the fastening column 203.
[0023] The locking block 103 is precisely fixed at the center of the support frame 102 by the interference fit or transition fit between the groove and the locking block 103, thus preventing the locking block from shifting.
[0024] Furthermore, the clamping column 203 is sleeved on the outer wall of the auxiliary support tube 202, and the side wall of the auxiliary support tube 202 is provided with a groove for use with the ball bearing 204.
[0025] The groove and the clamping post 203 are engaged to ensure coaxiality of the connection and avoid radial offset during adjustment.
[0026] Preferably, the positioning bolt 201 is provided with a chamfer, and the positioning bolt 201 is sleeved on the side wall of the auxiliary support pipe 202.
[0027] The auxiliary support tube 202 is connected to the guide component and fixedly installed on the side wall of the fastening column 203. It also provides an installation reference for the positioning bolt 201. Its rigid structure ensures the uniform transmission of force during the adjustment process and avoids local deformation.
[0028] It should be noted that a central column is provided at the center of the limiting block 206, and the floating pin bracket 207 is sleeved on the side wall of the central column of the limiting block 206.
[0029] The limiting block 206 is a guide and positioning component, which is fixed to the side wall of the clamping plate 205. The central column set in the center of the block provides axial guidance for the floating pin 207, restricting the floating pin to only move in a straight line along the central column and avoiding lateral deviation.
[0030] Preferably, the shock-absorbing spring 208 is placed on the side wall of the positioning bolt 201, and the side wall of the shock-absorbing spring 208 is provided with a positioning plate that cooperates with the floating pin bracket 207.
[0031] The floating pin 207 is fitted onto the central column of the limiting block 206 and can extend and retract freely along the central column.
[0032] In use, the process begins with a fixing phase. The positioning pin 101 achieves rigid positioning with the external reference component. The support frame 102, through its side wall groove, precisely engages with the locking block 103, fixing the locking block 103 in the center position. Subsequently, the locking block 103 engages with the clamping column 203 through its internal groove. Next, the adjustment phase begins. Rotating the clamping column 203 causes it to move axially through its threaded connection with the support frame 102, thereby driving the auxiliary support tube 202 and the positioning pin 201 to move synchronously. Simultaneously, the ball bearings 204, slidingly mounted on the inner wall of the clamping column 203, assist in the adjustment. The support tube 202 rolls within the groove on its side wall, reducing adjustment resistance and ensuring transmission stability. Finally, the chamfered structure of the positioning bolt 201 achieves precise fit with the externally fixed component. When the device is subjected to axial vibration or impact, it enters the damping stage. The floating pin frame 207 extends and retracts axially along the central column of the limiting block 206. The vibration energy is absorbed by compressing or stretching the damping spring 208 placed on the side wall of the positioning bolt 201. The axial limiting of the ball 204 by the clamping plate 205 and the guiding effect of the limiting block 206 on the floating pin frame 207 ensure the stable movement of the damping structure.
[0033] In summary, the locating pin 101 in the fixing component 100 provides a stable reference through cylindrical surface engagement. The support frame 102 and the locking block 103 adopt an interference or transition fit and are center-limited to prevent displacement. The self-locking threaded pair formed by the threaded structure of the support frame 102 and the fastening column 203, and the groove engagement between the locking block 103 and the fastening column 203, achieve double fixing, ensuring stable locking and preventing assembly reference drift. The adjusting component 200 adopts a threaded drive and rolling friction design. The threaded engagement between the fastening column 203 and the support frame 102 enables fine adjustment, and the ball bearing 204... The rolling transmission between the inner wall of the clamping column 203 and the groove of the auxiliary support tube 202 reduces adjustment resistance and wear. The chamfered structure of the positioning bolt 201 adapts to different profile mounting surfaces, enabling flexible and efficient adjustment and quick locking, meeting the needs of multiple specifications. The built-in shock-absorbing buffer unit absorbs vibration impact energy through the elastic cooperation of the floating pin frame 207 and the shock-absorbing spring 208. The central column of the limiting block 206 provides axial guidance, and the clamping plate 205 ensures the axial positioning of the ball 204, achieving reliable shock absorption and protection, protecting precision components and improving assembly consistency.
