In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0026] Example 1: like Figures 1 to 4 As shown, the present invention provides a clamping fixture for the maintenance of new energy vehicle batteries, which mainly includes a lower guide rail 1, a drive motor 2, a clamping assembly 3 and a clamping claw 4.

[0027] refer to Figure 1 and Figure 3The lower guide rail 1 serves as the basic support and moving guide component of the entire fixture. A drive rail 103 is located at its center, engaging or cooperating with the transmission mechanism at the bottom of the clamping assembly 3. Below the drive rail 103, multiple parallel pad rails 104 are arranged. These pad rails 104 work together to provide a stable support plane for the clamping assembly 3, effectively preventing swaying or overturning during movement and ensuring smooth operation. Outer protective plates 101 are fixedly installed on both sides of the lower guide rail 1, serving as dustproof and safety protection. An external connecting strip 102 is also provided on the outer side of the lower guide rail 1. Through this strip, the entire clamping fixture can be easily installed and fixed onto an external maintenance platform, mobile trolley, or robotic arm, achieving modular integration.

[0028] The drive motor 2 is fixedly installed at an appropriate position at the end or side of the lower guide rail 1, and its output end is connected to the clamping assembly 3 through a transmission mechanism. When the drive motor 2 is started, the entire clamping assembly 3 can be precisely driven to move laterally along the axial direction of the lower guide rail 1, thereby adjusting the horizontal position of the clamping claw 4 to adapt to battery packs of different sizes or different maintenance stations.

[0029] refer to Figure 1 and Figure 2 The clamping assembly 3 is the core component for achieving clamping and rotation functions. It houses a rotary drive motor 301, preferably a servo motor or stepper motor, to achieve precise control of the rotation angle. The output end of the rotary drive motor 301 is coaxially and fixedly connected to the output shaft 302. A rotating sleeve 305 is connected to the end of the output shaft 302, which is used to fix the clamping jaws 4. Between the output shaft 302 and the rotating sleeve 305, a pad 303 and an outer mounting plate 304 are sequentially arranged. The pad 303 can be used to adjust the clearance and provide cushioning, while the outer mounting plate 304 enhances the rigidity of the entire transmission structure. The pad 303 and the outer mounting plate 304 cooperate with the output shaft 302 through bearings and other components, jointly ensuring the axial and radial stability of the output shaft 302 during high-speed or high-load rotation, making the rotation of the clamping jaws 4 smoother and more reliable.

[0030] refer to Figure 1 , Figure 2 and Figure 4 The clamping claws 4 are provided in pairs and symmetrically installed on both sides of the rotating sleeve 305 of the clamping assembly 3. Each clamping claw 4 mainly includes an outer drive block 401, a main clamping plate 402, and an auxiliary clamping plate 403. The outer drive block 401 serves as a power interface, connecting to the drive source inside the clamping assembly 3 to receive driving force. The main clamping plate 402 is the main load-bearing and clamping component, and its inner shape can be matched with the shape of the battery pack. The auxiliary clamping plate 403 is fixed to the upper end of the main clamping plate 402 by bolts or welding, etc., and is used to assist in positioning and clamping the battery pack from above.

[0031] Specifically, the auxiliary clamping plate 403 is provided with multiple upper heat dissipation holes 11 and inner heat dissipation holes 12. When clamping the battery pack, these heat dissipation holes can form an airflow channel between the battery pack surface and the clamping claws, effectively removing the heat generated by the battery during maintenance, improving the heat dissipation performance of the entire clamping process, and enhancing operational safety.

[0032] The working process of this utility model is as follows: First, the clamping assembly 3 is moved by the drive motor 2, causing a pair of clamping claws 4 to move to both sides of the battery pack. Then, the drive mechanism inside the clamping assembly 3 is activated, pushing the main clamping plate 402 and the auxiliary clamping plate 403 to close via the outer drive block 401, thereby stably clamping the battery pack. If the angle of the battery pack needs to be adjusted for maintenance, the rotary drive motor 301 can be started, driving the entire clamping claw 4 and the clamped battery pack to rotate to the required angle via the output shaft 302 and the rotating sleeve 305. During this process, the structure of the lower guide rail 1 ensures the stability of horizontal movement, while the internal structure of the clamping assembly 3 ensures the smoothness of rotation, and the heat dissipation holes on the auxiliary clamping plate 403 continuously provide heat dissipation.

[0033] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0034] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0035] The above description is merely an embodiment of this application and is not intended to limit the scope of this application.
