Description

TECHNICAL FIELD

[0001] The present application belongs to the field of electric vehicle lighting systems, and particularly relates to a front combination lamp for a two-wheeled electric vehicle and an electric vehicle using the same. BACKGROUND

[0002] With the development of the two-wheeled electric vehicle market, the overall vehicle design tends to be miniaturized and integrated, and the electrical connection between the electrical devices (including the handlebar, brake handle, switch, horn, instrument, turn signal, etc.) at the front of the vehicle becomes more complex. In order to achieve a simple appearance design and higher protection standards, a large number of wire harnesses need to be arranged and placed in the front combination lamp after being connected through an adapter plate.

[0003] In the prior art, some miniaturized and front panel-free designed two-wheeled electric vehicles often place the electrical device wire harness and the main wire harness in the external front part of the vehicle or protect them through a fixing device (such as a waterproof box) after being connected through an adapter plate. Although the modularity and protection requirements of the electrical connection are achieved to some extent, the existing structure still has the following problems:

[0004] Complex structure, inconvenient installation: the existing design often fixes the adapter plate on the outside of the lamp or in the waterproof box through screws or buckle structures, such as CN202322126865.X, entitled "Vehicle lamp with waterproof device for electrical connector and electric vehicle", which achieves the waterproof requirement of the combination lamp, but the assembly and disassembly are complicated, which is not conducive to later maintenance and maintenance.

[0005] Low space utilization: the adapter plate is installed on the outside of the lamp body or fixed on the vehicle frame or vehicle shell through an independent waterproof box, which occupies the limited space at the front of the vehicle and limits the layout of other components, especially for two-wheeled electric vehicles without a front windshield, the impact is particularly significant.

[0006] Insufficient waterproof performance: the existing adapter plate is often exposed outside the combination lamp housing, although auxiliary structures such as waterproof boxes are used, but there are still sealing dead angles when the connection wire harness is drawn out from the waterproof box, which is prone to water ingress. Once water enters, the connector will be affected by rust or short circuit, which will affect the normal operation of the vehicle electrical system.

[0007] Difficulty in wire harness arrangement: the traditional adapter plate uses screws, buckles and other fixing methods, which makes the disassembly and assembly of the adapter plate and the wire harness complicated, increases the assembly and later maintenance difficulty, and affects the production efficiency and service convenience.

[0008] Based on the above problems, there is an urgent need for a front combination lamp structure that is compact in structure, easy to operate, good in waterproof performance, and convenient for wire harness arrangement to solve the above problems of the prior art. SUMMARY

[0009] The present application aims at solving the problems in the prior art, and provides a front combination lamp for a two-wheeled electric vehicle and an electric vehicle using the same.

[0010] To solve the above technical problems, the present application adopts the following technical method: the present application discloses a front combination lamp for a two-wheeled electric vehicle, comprising a front combination lamp shell and an adapter plate, characterized in that the front combination lamp shell is provided with an adapter plate placement bin for placing the adapter plate; the adapter plate placement bin opening faces the bottom of the front combination lamp shell.

[0011] A wire pressing plate matching the size of the adapter plate placement bin opening is arranged at the bottom of the front combination lamp shell.

[0012] Further, the wire pressing plate comprises a wire pressing plate body and a locking piece arranged on one side of the wire pressing plate body, and the bottom of the front combination lamp shell is provided with a locking hole matching the locking piece.

[0013] Further, the locking piece is provided with a limiting piece on one side; the limiting piece comprises an upper limiting plate and a lower limiting plate, and the upper limiting plate and the lower limiting plate are arranged on the upper and lower sides of the bottom wall of the front combination lamp shell.

[0014] Further, the upper limiting plate is longer than the lower limiting plate.

[0015] Further, the wire pressing plate body is further provided with an extension plate extending into the front combination lamp shell and a limiting baffle blocking the extension plate from extending too much; the bottom of the front combination lamp shell is provided with a gap for the extension plate to extend into and a supporting wall supporting the limiting baffle.

[0016] Further, the supporting wall is provided with a groove matching the limiting baffle.

[0017] Further, along the length direction of the wire pressing plate, the locking piece and the extension plate are arranged on the two sides of the wire pressing plate body.

[0018] Further, the locking piece and the limiting piece are located on the same side of the wire pressing plate body.

[0019] Further, the adapter plate is provided with a wire harness, and the other end of the wire harness extends out of the front combination lamp shell and is used for electrically connecting with the main wire harness of the electric vehicle body.

[0020] The present application further discloses a two-wheeled electric vehicle, comprising a two-wheeled electric vehicle frame and a front combination lamp provided on the front end of the two-wheeled electric vehicle frame and comprising the above-mentioned front combination lamp. Advantages

[0021] 1. Compared with the prior art, the application places the adapter board in the adapter board placing bin inside the front combination lamp shell, and adopts the wire pressing plate to design the closing structure of the opening of the placing bin, so that the adapter board and the wire harness are arranged in the internal space of the front combination lamp shell. Compared with the prior art that the adapter board is installed exposed outside the lamp body or needs to be separately designed waterproof box, the scheme relies on the overall sealing and structure integration of the shell, improves the protection performance of the adapter board and the wire harness, effectively blocks the invasion of external environmental factors such as rain and dust, thereby realizing stable and reliable waterproof and dustproof effect, and guaranteeing the electrical safety of the wire harness connection.

[0022] 2. The adapter board and the wire harness are uniformly wired and pressed through the adapter board placing bin, and the wire pressing plate arranged at the bottom of the combination lamp shell is cooperated to realize quick installation and fixation through the limiting structures such as the locking piece and the limiting piece, so that the cumbersome operation of separately arranging the wire harness and the plug-in part in the traditional scheme is omitted. The design not only simplifies the wiring process of the front wire harness, but also makes the wire harness disassembly and assembly more convenient, and greatly improves the vehicle production and assembly efficiency and the later maintenance convenience.

[0023] 3. The adapter board and the wire harness are integrated into the internal structure of the front combination lamp shell, and are effectively accommodated by the reserved adapter board placing bin, so that the problem of occupying the limited space of the front frame due to the external adapter board or the additional installation of the protection component (such as the waterproof box) in the prior art is avoided. The integrated design of the shell not only improves the space utilization, makes the front combination lamp structure more compact, but also reduces the number of components and the manufacturing and assembly cost. In addition, the wire pressing plate and the locking structure designed by using the standardized module also help to reduce the machining difficulty of parts and the assembly error, and further optimize the consistency and reliability of the product.
