[0019] The specific embodiments of the utility model are further explained in detail by comparing the drawings and describing the embodiments, the purpose is to help the technical personnel in the field to have more complete, accurate and deep understanding to the inventive concept and technical scheme of the utility model, and help its implementation.

[0020] As Figures 1 to 3As shown, the battery pack fixing structure includes a battery pack base 1, a support 4 and a lock catch 6 are arranged on the battery pack base 1, the battery pack 2 is located between the support 4 and the lock catch 6, the support 4 is hingedly connected with a limiting plate 5 at the top end, the limiting plate 5 is provided with a hook 10 at the end, the lock catch 6 includes a clasp 8, the clasp 8 cooperates with the hook 10, and a limiting structure is further arranged on the battery pack base 1. The battery pack base 1 is used for bearing the battery pack 2, and is of a square structure, which is simple in structure and convenient to process. The lock catch 6 is hingedly connected at the end of the battery pack base 1, the clasp 8 is hingedly connected on the lock catch 6, the hook 10 is designed at the front end of the limiting plate 5 and used for connecting the lock catch 6 through the clasp 8, and the limiting plate 5 cooperates with the lock catch 6 to realize the fixing and unlocking of the battery pack 2. The lock catch 6 is a commonly used lock catch 6, which is simple in operation mode and can be quickly locked or opened, and can be manually and quickly fixed and tightened or unlocked.

[0021] As shown in Figure 1 and Figure 2 , the limiting structure includes a self-locking wedge 3, the self-locking wedge 3 includes a pin shaft 7, the self-locking wedge 3 is hingedly connected at the end of the battery pack base 1 through the pin shaft 7, and the self-locking wedge 3 abuts against the outer side of the battery pack 2. The self-locking wedge 3 is used for limiting the movement of the battery pack 2 in two directions, and stabilizes the posture of the battery pack 2. The self-locking wedge 3 is rotatable, and can be used in the pushing installation and extraction disassembly process of the battery pack 2, and cooperates with the lock catch 6 and the limiting plate 5 to limit the movement of the battery pack 2 in multiple directions, thereby improving the stability of the battery pack 2. Since the self-locking wedge 3 is hingedly connected on the battery pack base 1, the battery pack 2 can be fixed by pushing installation, thereby effectively saving the carrying time and making the operation more labor-saving.

[0022] As shown in Figure 1 and Figure 2 , the self-locking wedge 3 is V-shaped. A single V-shaped self-locking wedge 3 can form two surface contact limits on the outer side of the battery pack 2, thereby improving the stability of the battery pack 2. The included angle of the two clamping surfaces of the self-locking wedge 3 is designed synchronously with the corner angle of the battery pack 2. For battery packs 2 of different sizes, only the position of the self-locking wedge 3 needs to be changed.

[0023] As shown in Figure 3 , a buffer pad 9 is arranged on the inner side of the lock catch 6. The buffer pad 9 is arranged between the battery pack 2 and the lock catch 6, is closely attached to the battery pack 2, further limits the movement of the battery pack 2, and can reduce the adverse effects of excessive locking force on the shell structure of the battery pack 2. The buffer pad 9 can be directly bonded on the inner side of the lock catch 6 by using a soft rubber strip, thereby reducing the installation difficulty.

[0024] As shown in Figure 1 , the limiting plate 5 is located at the middle of the upper end of the battery pack 2. After the battery pack 2 is installed, the limiting plate 5 can be used as a judgment reference for whether the battery pack 2 is accurately installed. Figure 3As shown, the one side of the battery pack 2 is in the same plane with the one side of the battery pack base 1. The above structure can be used as the judgment reference of whether the battery pack 2 is installed in place, which is convenient for the operator to adjust.

[0025] As shown in Figure 1 and Figure 2 As shown, the self-locking wedge 3 is provided with two, and the two self-locking wedges 3 are symmetrically arranged about the bracket 4. The two self-locking wedges 3 are used together to limit three faces of the battery pack 2, so as to achieve the effect of plane positioning.

[0026] As shown in Figure 3 The hook 10 is a U-shaped structure. The U-shaped hook 10 is matched with the snap ring 8, and the snap ring 8 is reliably fixed and limited.

[0027] When the battery pack 2 is fixed: the battery pack 2 is pushed along the direction of the bracket 4, and the end of the battery pack 2 contacts the inner side of the self-locking wedge 3, the battery pack 2 is pushed, the V-shaped self-locking wedge 3 is rotated under the pin shaft 7 and abuts against the outer side of the battery pack 2, so as to realize automatic locking, then the limiting plate 5 is pulled down, and after being locked by the lock buckle 6, the buffer pad 9 is tightly attached to the battery pack 2. The unlocking process of the battery pack 2 is implemented in reverse of the above steps, that is, the lock buckle 6 is unlocked and rotated downward, and the limiting plate 5 is rotated upward, so that the battery pack 2 can be manually pulled out, and the V-shaped self-locking wedge 3 is automatically unlocked, so that the battery pack 2 can be conveniently disassembled.

[0028] The battery pack fixing structure can realize manual quick fixing and tightening and manual quick opening when the battery pack 2 is replaced, solves the problems of complex structure and inability to manually and quickly fix and unlock of the existing battery pack fixing structure, reduces the manual battery replacement operation time and difficulty, and improves the replacement efficiency; compared with the existing traditional electric battery pack fixing technology, the battery pack fixing structure has the advantages of simple structure, convenient operation, low cost, time saving, reliable fixing, etc., and the quick battery replacement can be completed without tools, which is beneficial to the quick promotion of the quick battery pack and has great market prospect.

[0029] The utility model is described exemplarily above in combination with the drawings. Apparently, the specific implementation of the utility model is not limited by the above manner. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the above concept and technical scheme of the utility model are directly applied to other occasions without improvement, all of them are within the protection scope of the utility model.
