Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and in particular to a water-blocking structure, a frame, and an electric bicycle. Background Technology

[0002] Electric bicycle batteries are usually located under the pedals or the rear seat. When riding in the rain or on flooded roads, water splashed out by the rear wheel can easily fall directly onto the battery, battery compartment, and wiring harness connectors. After being exposed to rainwater for a long time, these components are prone to malfunctions such as battery wiring harness aging, poor contact, or even short circuits. At the same time, it can also cause corrosion to the battery compartment, reduce the strength of the frame, and affect riding safety.

[0003] To address this, related technologies have added water deflectors to the vehicle frame to block water splashed out by the rear wheels, thus significantly reducing rainwater erosion. However, the water deflectors are installed with screws, and the installation location has limited space, making installation difficult and reducing assembly efficiency. Utility Model Content

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figures 1-6 As shown, this utility model provides a water-blocking structure, which is installed between the rear wheel and battery 1 of an electric bicycle to prevent water kicked up by the rear wheel during operation from falling onto the battery 1, battery compartment, and frame. The water-blocking structure includes a mounting plate 2 and a parking limit tube 4, both of which are fixedly connected to the frame. The mounting plate 2 is located above the parking limit tube 4. A water-blocking plate 3 is disposed between the mounting plate 2 and the parking limit tube 4. The upper end of the water-blocking plate 3 is engaged with the mounting plate 2, and the lower end of the water-blocking plate 3 is provided with a first limiting structure 331 and a second limiting structure 332. The first limiting structure 331 and the second limiting structure 332 respectively contact the two sides of the parking limit tube 4. The first limiting structure 331 restricts the movement of the water-blocking plate 3 in a first direction, and the second limiting structure 332 restricts the movement of the water-blocking plate 3 in a second direction, which are opposite in direction. By engaging the upper end of the baffle plate 3 with the mounting plate 2, and by setting the first limiting structure 331 and the second limiting structure 332 at the lower end of the baffle plate 3 to contact both sides of the parking limit tube 4, the movement of the baffle plate 3 is restricted. The baffle plate 3 does not require screw assembly and has a smaller assembly space requirement, reducing the difficulty of assembly operations and improving assembly efficiency. The main structure of the mounting plate 2 in this embodiment is similar to that of the mounting plate 2 in the prior art. Specifically, the structure of the connection between the mounting plate 2 and the frame in this embodiment is the same as that in the prior art. Therefore, the connection method and related structure between the mounting plate 2 and the frame are not described in detail here. Similarly, the structure of the parking limit tube 4 in this embodiment is similar to that in the prior art. The structure of the connection between the parking limit tube 4 and the frame in this embodiment is the same as that in the prior art. Therefore, the connection method and related structure between the parking limit tube 4 and the frame are also not described in detail here.

[0030] Furthermore, such as Figures 4-6 As shown, the water-blocking structure includes an upper connecting part 31, a connecting part 32, and a lower connecting part 33. The upper connecting part 31 and the lower connecting part 33 are connected by the connecting part 32. The upper connecting part 31, the connecting part 32, and the lower connecting part 33 are arranged sequentially from top to bottom. The water-blocking plate 3 is made of plastic or rubber, and the upper connecting part 31, the connecting part 32, and the lower connecting part 33 are integrally formed. The upper connecting part 31 and the lower connecting part 33 are arranged in parallel, thereby avoiding other components on the frame. The first limiting structure 331 and the second limiting structure 332 are both located at the bottom end of the lower connecting part 33 and are spaced apart along the length direction of the lower connecting part 33, that is, spaced apart along the width direction of the frame. In this embodiment, the first limiting structure 331 and the second limiting structure 332 respectively contact the parking limiting tube 4 on both sides along the length direction of the frame, thereby restricting the movement of the water-blocking plate 3 along the length direction of the frame. Then, the water-blocking plate 3 is fixed by engaging with the mounting plate 2. Please refer to... Figure 4 and combined Figure 6 As shown, there are two first limiting structures 331, which are respectively set at both ends of the lower connecting part 33. The second limiting structure 332 is set between the two first limiting structures 331. This arrangement can further prevent the baffle plate 3 from deflecting.

[0031] Furthermore, please refer to Figures 2-5 As shown, a snap-fit ​​seat 21 is provided on the mounting plate 2. The snap-fit ​​seat 21 has a snap-fit ​​hole, and the top of the upper connecting part 31 has a receiving groove 311. A buckle 312 is provided in the receiving groove 311. The receiving groove 311 is used to accommodate the snap-fit ​​seat 21, and the buckle 312 passes through the snap-fit ​​hole and snaps into the snap-fit ​​seat 21. By providing the receiving groove 311 to accommodate the snap-fit ​​seat 21, the installation space required when installing the water baffle 3 is smaller, so that the water baffle structure can be used for more frame sizes. There are two snap-fit ​​seats 21, which are spaced apart along the length of the mounting plate 2. There are also two buckles 312, which are spaced apart along the length of the upper connecting part 31. The two buckles 312 correspond one-to-one with the two snap-fit ​​seats 21. The upper connecting part 31 of the water baffle 3 is snapped into the mounting plate 2 by the two buckles 312, which improves the structural strength of the joint.

[0032] Specifically, such as Figures 4-5As shown, the latch 312 includes two opposing sub-clamping blocks 3122, both of which are capable of elastic deformation. Both sub-clamping blocks 3122 are used to pass through the clamping holes of the clamping seat 21 and engage with it. Each sub-clamping block 3122 has a deformation groove 3121, which provides deformation space for the sub-clamping blocks 3122. During the engagement process, the two sub-clamping blocks 3122 pass through the clamping holes of the clamping seat 21 and simultaneously undergo elastic deformation towards the deformation space. After exiting the clamping holes, the two sub-clamping blocks 3122 return to their initial state under their own elastic force, completing the engagement with the clamping seat 21. The deformation space design makes the engagement process smoother.

[0033] Furthermore, please refer to Figure 6 As shown, multiple raised ribs 34 are spaced apart on the baffle plate 3, all extending along the height direction of the baffle plate 3. The presence of multiple raised ribs 34 enhances the structural strength of the baffle plate 3. Simultaneously, multiple water guide channels 35 are also spaced apart on the baffle plate 3, extending along the height direction of the baffle plate 3, and are staggered with the raised ribs 34. The water guide channels 35 can be formed by sandwiching adjacent raised ribs 34, or by forming grooves on the baffle plate 3 in the direction opposite to the protruding direction of the raised ribs 34. The placement of the water guide channels 35 facilitates the rapid dispersion and guidance of water splashes or flows to the ground, preventing excessive accumulation of water splashes or flows on the baffle plate 3 in a short period and their spread to the battery 1 and battery compartment.

[0034] This utility model provides a vehicle frame, including the water-blocking structure in this embodiment. By setting the water-blocking structure in this embodiment, the battery 1 and the battery compartment are effectively protected. At the same time, the water-blocking structure is easier to install and has higher installation efficiency.

[0035] This utility model provides an electric bicycle, including a battery 1 and a frame as described in this embodiment. The battery 1 is mounted on the frame and is protected by a water-blocking structure to ensure the driving safety of the electric bicycle.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
