Description

Technical Field

[0001] This utility model relates to the technical field of front-end components for two-wheeled vehicles, and in particular to a waterproof front-end structure. Background Technology

[0002] Electric scooters are vehicles that are based on traditional human-powered skateboards and equipped with electric motors.

[0003] Traditional scooter cables suffer from several core defects, including poor sealing structure reliability, weak protection at connection points, and easy aging and failure of waterproof materials. These problems directly lead to water ingress and short circuits in the cables, as well as damage to electronic components, seriously affecting the safety and lifespan of the scooter.

[0004] Traditional scooters often use rubber waterproof clamps to seal the cable passage holes, but the vibrations during scooter riding can easily cause the waterproof clamps to fall off the cable passage holes, directly causing the seal to fail.

[0005] The cables for components such as the electronic brake lever and turn signals on the handlebars of scooters are mostly segmented, with the connection terminals simply wrapped with insulating tape or plastic sheaths, without professional waterproof sealing. Rainwater can easily seep in from the connection points, causing short circuits or leakage. Utility Model Content

[0006] This application addresses the shortcomings of the existing production technology by providing a reasonably structured waterproof forehead structure. A waterproof and sealed space is provided in the upper half of the forehead component's housing, and multiple cables are neatly led out from the multiple side walls of the waterproof and sealed space, ensuring waterproof performance while also facilitating cable management.

[0007] The technical solution adopted in this utility model is as follows: A waterproof structure for the forehead, defining the x-direction as the line connecting the two horizontal ends, and defining the y-direction and z-direction. The horizontally attached housing is provided, and a waterproof and sealed cavity is provided inside the housing. The waterproof and sealed cavity has wire guide plugs on its side walls in the xz plane and yz plane. After the vehicle cable passes through the waterproof and sealed cavity, it is led out through several of the wire guide plugs.

[0008] As a further improvement to the above technical solution: The housing includes: The upper housing is located on the side of the handle that faces away from the ground in the z-direction. The lower housing is located on the side of the handle that is transverse in the z-direction closer to the ground. The waterproof and sealed cavity is built into the upper shell.

[0009] The waterproof sealed cavity is open on the side facing the ground in the z-direction.

[0010] The waterproof and airtight cavity has a cubic or cylindrical structure. The axis of the waterproof sealed cavity is located in the x-direction.

[0011] The waterproof sealed cavity includes: The first sidewall is located on the xz plane. The second sidewall is located on the yz plane and connects to the edge of the first sidewall in the x direction. The third sidewall is located on the yz plane and is connected to the edge of the first sidewall on the side opposite to the second sidewall in the x direction.

[0012] The connecting wall surface between the first sidewall, the second sidewall and the third sidewall is at least one of a straight wall, an arc wall and a folded wall.

[0013] Cable guides are provided on the first sidewall, the second sidewall, and the third sidewall, and the number of cables passing through each cable guide is equal.

[0014] Holes are provided on the first sidewall, the second sidewall, and the third sidewall, and the wire plug is interference-fitted into the hole or bonded and fixed into the hole.

[0015] The open side of the waterproof sealed cavity is assembled and sealed with the lower shell.

[0016] A sealing ring is provided between the open side of the waterproof sealed cavity and the lower shell.

[0017] The upper housing and the lower housing are snap-fitted together, and when the upper housing and the lower housing are snapped together, a compressive force is applied to the sealing ring.

[0018] The beneficial effects of this utility model are as follows: This utility model simplifies the forehead assembly into a structure in which the upper and lower shells are snapped together. A waterproof and sealed space is set up inside the upper shell, and multiple cables are led out from the side wall of the waterproof and sealed space. This results in only two cables on each side of the handlebars and only two cables on the side of the handlebars facing the rider. The multiple cables are evenly distributed and led out from three directions. Furthermore, the connectors of the multiple cables are placed in the waterproof and sealed space to protect the cable connectors from moisture.

[0019] The waterproof and sealed space is built into the upper shell, meaning that the top of the waterproof and sealed space is closed and the bottom is open. With this structure, the probability of water leaking into the waterproof and sealed space is much smaller.

[0020] In addition, the waterproof and sealed space is equipped with a sealing ring, which is located on the open side of the waterproof and sealed space to seal the leaking gaps on the assembly surfaces of the upper and lower shells, further ensuring the watertight effect.

[0021] The waterproof and sealed space is equipped with wire-passing plugs on its side walls. The wire-passing plugs are installed on all three side walls of the waterproof and sealed space, and the number of cables that can pass through each wire-passing plug is similar, so that the deformation degree of each wire-passing plug is similar. This will prevent the valve of the wire-passing plug from deforming excessively and creating a large gap due to an excessive number of cables in one place. Attached Figure Description

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0030] Example 1: like Figure 1 The figure shown is an overall assembly diagram of the front structure of the vehicle in this embodiment. Figure 2 This is an exploded view of the front structure of the vehicle in this embodiment.

[0031] Depend on Figure 2As can be seen, an upper housing 20 and a lower housing 50 are respectively provided on the upper and lower sides of the horizontal 10. The upper housing 20 and the lower housing 50 can be fastened together by fasteners or by snap-fit, so that the upper housing 20 and the lower housing 50 cover the horizontal 10, forming a housing with a hollow space inside. The top of the upper housing 20 is provided with an instrument assembly 30.

[0032] Reference Figures 3-5 In order to achieve a sealed and waterproof environment, a waterproof and airtight cavity 300 is provided inside the upper shell 20. The waterproof and airtight cavity 300 is a semi-enclosed open space. The waterproof and airtight cavity 300 is open on the side facing the ground in the z direction, and the rest is a wall.

[0033] The waterproof sealed cavity 300 is a cylindrical structure with its axis falling in the x-direction, having two sidewalls perpendicular to the x-direction and at least one sidewall parallel to the x-direction. In this embodiment, holes are made in the three sidewalls and wire plugs 70 are embedded therein, allowing two cables to pass through each wire plug 70.

[0034] The specific wiring structure of the cable is as follows: like Figure 4 In the middle position, there are left and right sides in the x direction. On the left side wall of the waterproof sealed cavity 300, that is, on the second side wall 302, the turn signal switch cable 60 and the left brake lever electronic cable 61 pass through. On the right side wall, that is, on the third side wall 303, the throttle electronic cable 62 and the right brake lever electronic cable 63 pass through. Between the left and right side walls is the first side wall 301, on which the turn signal electronic cable 31 and the instrument electronic cable 32 pass through.

[0035] The connectors of the turn signal switch cable 60, left brake lever electronic cable 61, throttle electronic cable 62, right brake lever electronic cable 63, turn signal electronic cable 31, and instrument panel electronic cable 32 are located within the waterproof sealed cavity 300, and as... Figure 2 As shown, the upper shell 20 covers the waterproof sealed cavity 300, effectively protecting the joint portion inside the waterproof sealed cavity 300.

[0036] When the upper shell 20 and the lower shell 50 are fastened together, they can perfectly seal the open part of the waterproof sealed cavity 300, achieving the purpose of full waterproofing.

[0037] Example 2: Based on Embodiment 1, a sealing ring 40 is provided at the opening of the waterproof sealed cavity 300. When the upper shell 20 and the lower shell 50 are fastened together, because the sealing ring 40 has a certain thickness and there are other mating structures inside the upper shell 20 and the lower shell 50, these mating structures will exert a clamping force on the sealing ring 40, causing the sealing ring 40 to be compressed to a certain degree of deformation. Due to its elastic restoring force, the deformed sealing ring 40 has a better waterproof effect.

[0038] Example 3: like Figure 4 and Figure 5 As shown, the waterproof sealed cavity 300 has a prism structure, and a more special type is a quadrangular prism, i.e. a cube.

[0039] As an alternative implementation, the waterproof sealed cavity 300 can adopt a prismatic structure such as a triangular prism or a pentagonal prism. In the prismatic structure, the two end faces in the axial direction, that is, the two end faces in the x-direction, are the second sidewall 302 and the third sidewall 303, respectively. One of the sidewalls parallel to the axis serves as the first sidewall 301, resulting in the second sidewall 302 and the third sidewall 303 perpendicular to the first sidewall 301, which will not affect the cable outlet.

[0040] A cylindrical structure can also be used as an alternative for the waterproof sealed cavity 300, but it is difficult to install the wire plug 70 on the curved surface of the cylinder. Therefore, in this embodiment, a prism with straight sidewalls is preferred.

[0041] Example 4: As an optional implementation, based on Embodiment 2, by defining the first sidewall 301, the second sidewall 302, and the third sidewall 303 as straight surfaces, since only one surface needs to be left as an opening, the space enclosed by the first sidewall 301, the second sidewall 302, and the third sidewall 303 can be... Figure 5 and Figure 6 As shown, it is also necessary to connect the wall surface 304 to supplement the waterproof sealed cavity 300, so as to obtain a waterproof sealed cavity 300 that is only open on the bottom surface in the z direction.

[0042] The connecting wall 304 can be a straight surface, connecting between the first side wall 301, the second side wall 302, and the third side wall 303.

[0043] As an alternative implementation, the connecting wall 304 can also be curved. Since the connecting wall 304 does not need to be fitted with a wire guide 70, the curved structure will not affect the installation of other components.

[0044] As an alternative implementation, the connecting wall surface 304 can be a bent fold, that is, the waterproof sealed cavity 300 is a pentagonal prism or a prism with more than five facets.

[0045] As a further optimization of the folded structure, the fold can contain at least one curved surface, such as... Figure 6 As shown, for example, the folded surface has a straight surface connecting the second sidewall 302 and the third sidewall 303, and the space between the straight surface and the first sidewall 301, the second sidewall 302 and the third sidewall 303 is connected by an arc surface to reduce the possible rigid impact or deformation caused by too many right angles.

[0046] The advantage of this utility model is that it simplifies the traditional forehead assembly into a snap-fit ​​structure of upper shell 20 and lower shell 50, and places the cable connector in the waterproof sealed cavity 300 of upper shell 20. The snap-fit ​​of upper shell 20 and lower shell 50 achieves the first level of waterproofing, and the sealing ring 40 and waterproof sealed cavity 300 achieve the second level of waterproofing, ensuring the safety of the connector.
