[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] like Figures 1 to 2 As shown, a battery fixing bracket includes:

[0026] The main body 100 is provided with a receiving groove 101 for fixing the battery pack 400 along the length direction;

[0027] The buckle structure 200 includes a strap 210 that is openably mounted on the body 100, and a clamping portion 220 that is fixed to the body 100. The strap 210 has a closed state and an open state. When the strap 210 is in the closed state, it engages with the clamping portion 220 and restricts the movement of the battery pack 400 in the receiving slot 101. When the strap 210 is in the open state, the strap 210 is separated from the clamping portion 220 and allows the battery pack 400 in the receiving slot 101 to move in a direction perpendicular to the axis of the receiving slot 101. This design allows the battery pack 400 to be installed or removed in a radially movable manner, effectively saving the axial space required for installing the battery pack 400, and achieving adjustability when securing the battery pack 400, ensuring the security of the battery pack 400 when secured.

[0028] Specifically, if Figure 1 、 Figure 2 As shown, in this embodiment, the body 100 is a hollow structure, which includes a strip-shaped fixing portion 110, and a first supporting structure 120 and a second supporting structure 130 provided on the fixing portion 110. The first supporting structure 120, the second supporting structure 130 and the fixing portion 110 cooperate to form a receiving groove 101 for fixing the cylindrical battery pack 400. This design ensures the compactness of the overall structure and effectively reduces the installation space occupied.

[0029] In this embodiment, the fixing portion 110 extends along the axis of the body 100 and is provided with a fixing hole 111. The fixing hole 111 passes through the fixing portion 110, and there is a height difference between the fixing hole 111 and the receiving groove 101. This design allows the fixing portion 110 to serve as both a load-bearing structure for the battery fixing bracket and a connecting structure for the battery fixing bracket to be installed on the electric bicycle, effectively improving the structural utilization rate, simplifying the overall structure of the battery fixing bracket, and facilitating the fixing of the battery fixing bracket to the electric bicycle. In addition, the height difference design between the fixing hole 111 and the receiving groove 101 prevents the fixing hole 111 from interfering with the installation position of the battery pack 400, allowing the battery pack 400 to fit tightly against the fixing portion 110 when fixed in the receiving groove 101, effectively improving the stability of the placement of the battery pack 400.

[0030] In this embodiment, at least two groups of fixing holes 111 are provided and arranged in a straight line.

This design effectively increases the flexibility of the fixing holes 111 and allows the distance between the two mounting points to be adjusted through the fixing holes 111, allowing the battery mounting bracket to adapt to different installation requirements.

[0031] In this embodiment, the first support structure 120 includes a first support portion 121 and a second support portion 122, respectively, located on either side of the fixing portion 110. The first support portion 121 and the second support portion 122 both extend away from the fixing portion 110 and cooperate to form an arcuate support surface. Preferably, the arcuate support surface is semi-circular. This design effectively expands the contact area between the body 100 and the battery pack 400, improves the support effect on the battery pack 400, and makes the battery pack 400 more stable within the accommodating slot 101, reducing shaking.

[0032] In this embodiment, the second support structure 130 is disposed at the end of the fixed portion 110 away from the first support structure 120. It includes a third support portion 131 and a fourth support portion 132 located on either side of the fixed portion 110. The third support portion 131 and the fourth support portion 132 both extend away from the fixed portion 110 and cooperate to form an arcuate support surface. Preferably, the area of ​​the arcuate support surface is greater than the area of ​​the arcuate support surface formed by the first support portion 121 and the second support portion 122. This design further increases the contact area between the body 100 and the battery pack 400, improving the support effect on the battery pack 400, making the battery pack 400 more stable within the accommodating slot 101 and reducing shaking in multiple directions.

[0033] To further ensure the stability of the battery pack 400 when it is fixed, in this embodiment, the main body 100 is further provided with a first limiting portion 140 and a second limiting portion 150 arranged in opposite directions. The first limiting portion 140 and the second limiting portion 150 are respectively located at both ends of the fixing portion 110 and cooperate to limit the axial movement of the battery pack 400 within the accommodating slot 101. Preferably, in this embodiment, the first limiting portion 140 is annular and the second limiting portion 150 is L-shaped. When the battery pack 400 is installed in the accommodating slot 101, the first limiting portion 140 and the second limiting portion 150 respectively abut the ends of the battery pack 400. This design can prevent the battery pack 400 from shaking during the operation of the electric bicycle, further ensuring the stability and fixation of the battery pack 400 within the accommodating slot 101.

[0034] In this embodiment, the buckle structure 200 includes a clamping portion 220 fixed on the first support portion 121, and a strap 210 detachably provided on the second support portion 122, and the strap 210 has a closed state and an open state; when the strap 210 is in the closed state, the strap 210 is clamped with the clamping portion 220 and can limit the movement of the battery pack 400 in the accommodating slot 101, so that the battery pack 400 is firmly fixed in the accommodating slot 101; when the strap 210 is in the open state, the strap 210 is separated from the clamping portion 220 and can allow the battery pack 400 in the accommodating slot 101 to move in a direction perpendicular to the axis of the accommodating slot 101, so that the user can remove the battery pack 400 only by moving the battery pack 400 longitudinally, effectively saving the space for disassembly and assembly of the battery pack 400 when moving it horizontally, while achieving convenient disassembly and assembly and stability of the battery pack 400, and expanding the application range of the battery fixing bracket.

[0035] Preferably, in this embodiment, the clamping portion 220 is in the shape of a hook, which is fixed to one end of the first support portion 121 away from the fixing portion 110 and is integrally injection molded with the first support portion 121, effectively ensuring the strength of the clamping portion 220, and thereby ensuring the stability of the connection between the clamping portion 220 and the strap 210.

[0036] Preferably, in this embodiment, the strap 210 is a rubber or plastic member, with a fixing block 212 provided at one end thereof near the second support portion 122. The second support portion 122 is provided with a mounting slot 123 that is detachably connected to the fixing block 212. The mounting slot 123 is shorter than the length of the fixing block 212 but wider than the width of the strap 210. This design allows for convenient removal and maintenance of the strap 210 and also improves the ease of assembly and disassembly of the battery pack 400.

[0037] In this embodiment, the strap 210 is provided with a plurality of rectangular engaging holes 211 along its length.

When the engaging portion 220 is withdrawn from the engaging hole 211, the strap 210 separates from the engaging portion 220. The design of the multiple engaging holes 211 enables a flexible connection between the strap 210 and the engaging portion 220, allowing the battery fixing bracket to accommodate battery packs 400 of different sizes. The coordinated design of the engaging portion 220 and the engaging holes 211 also facilitates easy assembly and disassembly of the battery pack 400.

[0038] To reduce the risk of the battery pack 400 being stolen, this embodiment further includes a lock structure 300, which includes a fixing base 310 and a lock core 320. The fixing base 310 is provided on the third support portion 131. The lock core 320 is detachably provided in the fixing base 310 and forms a lock connection with the battery pack 400 in the receiving slot 101. The battery pack 400 has a lock hole 441. The lock core 320 has a locked state and an unlocked state. When the lock core 320 is in the locked state, the lock core 320 is engaged in the lock hole 441 and can restrict the movement of the battery pack 400 in the receiving slot 101. When the lock core 320 is in the unlocked state, the lock core 320 is withdrawn from the lock hole 441 and can allow the battery pack 400 in the receiving slot 101 to move. This design adds a locking mechanism to the battery fixing bracket through the lock structure 300, thereby reducing the risk of theft of the battery pack 400 after it is fixed and effectively improving the fixing security. Furthermore, the locking design enables the battery pack 400 to be quickly locked and unlocked, effectively improving the convenience of user operation.

[0039] It is worth noting that when the lock core 320 is in the unlocked state and the strap 210 is in the open state, the battery pack 400 is first moved along the axis of the battery pack 400 perpendicular to one end of the first limiting portion 140 to make the battery pack 400 inclined and the end portion outside the second support structure 130, and then moved along the axis of the battery pack 400 to the limiting groove 431 and separated from the second limiting portion 150, so that the battery pack 400 can be disassembled.

[0040] like Figures 1 to 4 As shown, the present invention also provides a battery pack 400, which includes a battery pack 400 and the above-mentioned battery fixing bracket, wherein the battery pack 400 and the battery fixing bracket are detachably connected.
