Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a battery mounting assembly 100, including a frame 110 and a battery box 120 and a pressure strip assembly 130 mounted on the frame 110. The battery box 120 is used to mount a battery 200, and the pressure strip assembly 130 is mounted above the battery box 120. An adjusting member 140 is mounted on the frame 110, and the pressure strip assembly 130 is located between the battery 200 and the adjusting member 140. By adjusting the relative position of the frame 110 and the adjusting member 140, the adjusting member 140 can be made to hold the pressure strip assembly 130.

[0028] Specifically, the battery box 120 has an internal space adapted to the size of common batteries 200. Its bottom and sides are made of a material with certain cushioning properties to reduce the direct impact of vibration on the battery 200. It also has drainage holes to prevent water accumulation and corrosion of the battery 200. The pressure strip assembly 130 is located above the battery box 120 and is made of a flexible material with a certain degree of friction, such as rubber. This allows it to fit tightly against the upper surface of the battery 200 without scratching its casing. The frame 110 is equipped with an adjusting component 140, which can be a screw, slide rail, or other structure. Taking a screw as an example, it is threaded onto the frame 110 and can be precisely adjusted by rotation. The pressure strip assembly 130 is located between the battery 200 and the adjusting member 140. By adjusting the relative position of the frame 110 and the adjusting member 140, the adjusting member 140 abuts against the pressure strip assembly 130, thereby evenly transmitting pressure to the battery 200 and firmly fixing it inside the battery box 120.

[0029] The battery mounting assembly 100 provided in this application includes a frame 110, a battery box 120, and a retaining strip assembly 130 mounted on the frame 110. The battery box 120 is used to mount a battery 200. The retaining strip assembly 130 is positioned above the battery box 120. An adjusting member 140 is provided on the frame 110. The retaining strip assembly 130 is located between the battery 200 and the adjusting member 140. By adjusting the relative position of the frame 110 and the adjusting member 140, the adjusting member 140 abuts against the retaining strip assembly 130. The adjusting member 140 allows this mounting assembly to adapt to batteries 200 of different specifications. Even with slight differences in size or shape, reliable mounting can be achieved with simple adjustments, broadening the application range and making it suitable for various models of electric vehicles, thus improving the product's versatility. By cooperating with the pressure strip assembly 130 and the adjusting component 140, pressure can be precisely applied according to the actual size and installation of the battery 200, so as to firmly fix the battery 200 in the battery box 120. This effectively avoids the battery 200 shaking due to vibration, ensures stable electrode connection, and provides continuous and stable power to the electric bicycle. It also eliminates potential hazards such as power interruption and abnormal power display during riding, and greatly improves riding safety.

[0030] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the pressure strip assembly 130 includes a first pressure strip 131 and a second pressure strip 132 that are parallel to each other. The first pressure strip 131 and the second pressure strip 132 are connected by a connecting strip 133, and the adjusting member 140 abuts against the connecting strip 133.

[0031] The pressure strip assembly 130 includes a first pressure strip 131 and a second pressure strip 132 that are parallel to each other. The design of these two pressure strips allows pressure to be applied from different areas of the battery 200, providing wider coverage and better fixation compared to a single pressure strip. The first pressure strip 131 and the second pressure strip 132 are connected by a connecting strip 133, forming a stable overall structure that ensures uniform and continuous pressure transmission. The connecting strip 133 not only serves as a connector but also acts as a support for the adjusting member 140, with the adjusting member 140 abutting against the connecting strip 133. When the adjusting member 140 is activated, for example, by rotating and advancing a screw-type adjusting member 140, pressure is evenly distributed to the first pressure strip 131 and the second pressure strip 132 through the connecting strip 133, thereby pressing the battery 200. The connecting strip 133 can be made of a metal material with moderate rigidity, such as aluminum alloy, ensuring strength for pressure transmission while being resistant to deformation, thus ensuring long-term stable operation.

[0032] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3As shown, the adjusting member 140 includes a first adjusting member 141 and a second adjusting member 142 corresponding to the connecting bar 133. The first adjusting member 141 and the second adjusting member 142 are respectively threadedly connected to the frame 110.

[0033] Specifically, the adjusting component 140 includes a first adjusting component 141 and a second adjusting component 142 corresponding to the connecting strip 133. This dual adjusting component 140 design allows for more precise control of the pressure bar assembly 130 on the battery 200. The first adjusting component 141 and the second adjusting component 142 are threadedly connected to the frame 110, using the threaded holes on the frame 110 as the mating structure. The threaded connection method features high precision and ease of operation; by rotating the adjusting component 140, its linear displacement relative to the frame 110 can be achieved. For example, the use of a fine-pitch thread design results in higher adjustment sensitivity; with each rotation, the advance or retreat distance of the adjusting component 140 is precisely controllable, enabling fine pressure adjustments based on the actual installation of the battery 200, meeting the different users' needs for tightness.

[0034] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the frame 110 is provided with a first threaded hole that is threadedly connected to the first adjusting member 141 and a second threaded hole that is threadedly connected to the second adjusting member 142.

[0035] Specifically, the precisely matched threaded holes provide a stable mounting position for the adjustment component 140, ensuring that the adjustment component 140 remains stable during long-term and frequent adjustments, and that the connection will not be loose, thus affecting the fixing effect on the battery 200 and ensuring the stability of the electric vehicle operation.

[0036] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, rubber pads 134 are provided at the ends of the first pressure strip 131, the second pressure strip 132 and the connecting strip 133, and the first pressure strip 131, the second pressure strip 132 and the connecting strip 133 abut against the battery 200 through the rubber pads 134.

[0037] Specifically, the rubber pad 134 provides an additional protective layer for the battery 200, buffering vibration and impact, preventing the pressure strip assembly 130 from hard contacting the battery 200 casing and causing scratches and wear, thus extending the lifespan of the battery 200; at the same time, with its strong friction, it enhances the fixing effect, ensuring that the battery 200 remains firmly in place even on bumpy roads.

[0038] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3As shown, the first pressure strip 131, the second pressure strip 132 and the connecting strip 133 are all provided with mounting grooves, through which the rubber pad 134 is installed.

[0039] Specifically, the specially designed mounting groove provides dedicated positioning for the rubber pad 134, ensuring accurate installation of the rubber pad 134 on the pressure strip assembly 130, enabling it to continuously and stably perform its cushioning and anti-slip functions, and improving the reliability of the battery 200 fixation.

[0040] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the frame 110 includes a left mounting pipe 111 and a right mounting pipe 112 arranged opposite to each other. The left mounting pipe 111 and the right mounting pipe 112 are connected by a first connecting pipe 113 and a second connecting pipe 114. The left mounting pipe 111, the right mounting pipe 112, the first connecting pipe 113, and the second connecting pipe 114 together form a space for accommodating the battery box 120. The frame 110 includes the left mounting pipe 111 and the right mounting pipe 112 arranged opposite to each other. As the main supporting structure of the frame 110, they have high strength and rigidity. They are generally made of seamless steel pipe, and the pipe diameter is selected according to the size of the battery box 120 and the load-bearing requirements. The left mounting pipe 111 and the right mounting pipe 112 are connected by the first connecting pipe 113 and the second connecting pipe 114 to form a stable frame structure, which together form the space for accommodating the battery box 120. The first connecting pipe 113 and the second connecting pipe 114 can be connected to the left and right mounting pipes 112 by welding to ensure a firm connection. The welds are inspected for defects to ensure they are free of defects and can withstand the weight of the battery 200 and the pressure strip assembly 130 without deformation. The frame 110, composed of the left and right mounting pipes 112 and the connecting pipes, provides a solid and reliable load-bearing foundation for the battery box 120 and the pressure strip assembly 130, ensuring that the entire fixing component structure remains stable and does not loosen or deform under various operating conditions such as vibration, acceleration, and braking of the electric bicycle, thus ensuring the safe fixing of the battery 200.

[0041] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the connecting strip 133 is provided with a first abutting groove that cooperates with the first adjusting member 141 and a second abutting groove that cooperates with the second adjusting member 142.

[0042] The connecting strip 133 is provided with a first abutment groove that mates with the first adjusting member 141 and a second abutment groove that mates with the second adjusting member 142. The abutment grooves are designed to make the contact between the adjusting member 140 and the connecting strip 133 more precise and stable. The first and second abutment grooves are circular grooves with a diameter slightly larger than the diameter of the screw of the adjusting member 140, ensuring that the bottom end of the screw is always located in the abutment groove during the rotation adjustment of the adjusting member 140, and will not shift or slip. The depth of the abutment groove is moderate, so that the bottom end of the screw just contacts the bottom of the groove and can apply stable pressure. The abutment groove provides a stable point of force for the adjusting member 140, ensuring that the pressure applied by the adjusting member 140 is accurately transmitted to the pressure strip assembly 130 through the connecting strip 133, thereby efficiently fixing the battery 200, avoiding pressure loss or uneven distribution due to poor contact, and improving the fixing effect.

[0043] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, mounting holes are provided on both the left mounting tube 111 and the right mounting tube 112, and the battery box 120 is provided with connection holes corresponding to the mounting holes.

[0044] Specifically, the precisely matched mounting holes and connection holes, combined with the bolt connection method, firmly fix the battery box 120 to the frame 110. Even when the electric bicycle vibrates violently, the battery box 120 will not loosen or fall off, providing a stable mounting base for the battery 200 and ensuring stable power supply.

[0045] This application also discloses an electric vehicle, including a vehicle body and the battery mounting assembly 100 from the foregoing embodiments. This electric vehicle has the same structure and beneficial effects as the battery mounting assembly 100 from the foregoing embodiments. The structure and beneficial effects of the battery mounting assembly 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
