Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle headlight and a vehicle. Background Technology

[0002] Vehicle lights play a crucial role in safe driving. Headlights, located at the front of the vehicle, primarily serve as illumination and signaling lights. The light emitted by headlights illuminates the road ahead, enabling drivers to drive safely at night. To ensure safety and adaptability during nighttime driving, headlights are generally adjustable, such as projector headlights. The projector lens assembly is typically mounted on the radiator, which is rotated and installed within the headlight housing via ball-head screws. By changing the angle of the radiator, the high and low beams of the headlights can be adjusted. However, in this structure, the ball joint and ball-head screws are generally positioned longitudinally relative to the headlight, resulting in a large longitudinal space. This compresses the safety clearance between the mudguard and the tire, and the deep internal structure of the headlight increases the risk of fogging.

[0003] Therefore, it is necessary to improve the mounting structure of the heat sink and lamp housing in the existing headlights, which can reduce the longitudinal depth of the headlights and reduce the risk of fogging inside the headlights. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a vehicle headlight and a vehicle, which improves the installation and mating structure of the heat sink and lamp housing of the headlight in the prior art, thereby reducing the longitudinal depth of the headlight and reducing the risk of fogging inside the headlight.

[0005] The present invention relates to a vehicle headlight, comprising a lamp housing and a headlight module. The lamp housing has a mounting portion for mounting the headlight module. The headlight module has a plurality of mounting ears along the transverse direction of the vehicle. The mounting portion has a mounting seat that mates with the mounting ears. The headlight module is supported and mounted on the mounting seat by the mounting ears and can rotate or lock around the axis of the mounting ears, so that the headlight module can perform pitching movements along the longitudinal direction of the vehicle.

[0006] Furthermore, the headlight module also includes a mounting ear limiting member. When the mounting ear is installed on the mounting base, the mounting ear limiting member spans both sides of the mounting base and is detachably and fixedly connected to the mounting part, and covers the top of the mounting ear to limit the mounting ear.

[0007] Furthermore, the headlight also includes a dimming assembly for driving the headlight module to rotate. The dimming assembly includes a dimming bolt and a dimming nut. The dimming nut is disposed on the headlight module. The dimming bolt passes through the lamp housing and the tail of the dimming bolt is threadedly connected to the dimming nut.

[0008] Furthermore, the headlight module also includes a heat sink and a lens disposed on the heat sink. The mounting ears are respectively disposed at both ends of the heat sink in the lateral direction. The shape of the mounting base is adapted to the shape of the mounting ears and can partially accommodate the mounting ears.

[0009] Furthermore, the dimming assembly also includes a backstop ring, which is sleeved on the outer circle of the end of the dimming bolt located inside the lamp housing;

[0010] The dimming nut is mounted on the heat sink.

[0011] Furthermore, the dimming assembly also includes a sealing ring, which is fitted onto the outer circle of the end of the dimming bolt located inside the lamp housing and is located between the anti-reverse ring and the inner wall of the lamp housing.

[0012] Furthermore, the mounting ear includes an operating handle and a connecting rod. The operating handle is fixedly connected to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to the radiator. The mounting base has a groove-shaped structure and can partially wrap around the mounting ear.

[0013] Furthermore, the mounting ear limiting member is provided with a limiting groove, and the radiator is provided with a limiting block corresponding to the limiting groove, the limiting block being located within the limiting groove.

[0014] The vehicle of this utility model includes the aforementioned vehicle headlight.

[0015] The beneficial effects of this utility model are as follows: The headlight and vehicle of this utility model are such that the headlight module can be rotatably mounted on the lamp housing via the mounting bracket, so that the pitch angle of the headlight module can be adjusted along the front-rear direction of the vehicle, thereby changing the beam angle of the headlight. Moreover, the mounting ears are set in the lateral direction of the headlight module, which, compared with the prior art where the mounting part of the headlight module is set along the longitudinal direction of the vehicle, can shorten the longitudinal depth of the headlight, reduce the cold zone inside the headlight, and thus reduce the risk of fogging inside the headlight.

[0023] Figure 1 This is a schematic diagram of the headlight structure of this utility model. Figure 2 This is a front view of the headlight with the lampshade concealed, according to this utility model. Figure 3 for Figure 2 Sectional view along the AA direction. Figure 4 for Figure 2 A sectional view along the BB direction, such as Figure 1-4 As shown: The vehicle headlight of this embodiment includes a lamp housing 3 and a headlight module. The lamp housing 3 is provided with a mounting part for mounting the headlight module. The headlight module is provided with a plurality of mounting ears 12 along the transverse direction of the vehicle. The mounting part is provided with a mounting seat 301 that cooperates with the mounting ears 12. The headlight module is supported and mounted on the mounting seat 301 through the mounting ears 12, and can rotate or lock around the axis of the mounting ears 12, so that the headlight module can complete the pitching action along the longitudinal direction of the vehicle. In this structure, the mounting ear 12 can be either a mounting pivot or a ball joint structure, both of which are acceptable. The lateral direction refers to the left and right direction relative to the vehicle. The headlight module generally includes a radiator 5, a lens 11, and a drive board 10 (circuit board), which are existing technologies and will not be described in detail here. The headlight module is mounted on the mounting base 301 via the mounting ear 12, thereby supporting the mounting on the mounting part. It can also rotate around an axis that is on the same lateral axis as the mounting ear 12, so that the pitch angle of the headlight module relative to the front and rear directions of the vehicle is adjustable, thereby changing the beam angle of the headlight to meet the needs of the driver. Compared with the existing technology that sets the mounting ear 12 in the longitudinal direction (relative to the front and rear directions of the vehicle), it can save the longitudinal space of the headlight, making the longitudinal depth of the headlight shallower. This allows the internal temperature circulation of the headlight to be better than that of the existing headlight, reducing the risk of fogging inside the headlight.

[0024] In this embodiment, the headlight module further includes a mounting ear limiting member 4. After the mounting ear 12 is installed on the mounting base 301, the mounting ear limiting member 4 spans both sides of the mounting base 301 and is detachably fixedly connected to the mounting portion, covering the top of the mounting ear 12 to limit the mounting ear 12. The mounting base 301 can partially accommodate the mounting ear 12, and the mounting ear limiting member 4 can be installed on the mounting portion with a self-tapping screw 1 for easy installation. The mounting ear limiting member 4 can also partially wrap around the mounting ear 12, so that the mounting ear limiting member 4 and the mounting base 301 constitute the installation space for the mounting ear 12. Compared with the prior art of using ball head screws and the mounting base 301 for interference fit, this method is easier to disassemble and install. When the headlight module needs to be replaced, the mounting structure itself will not be damaged, making it convenient for users to replace the headlight module according to their needs.

[0025] In this embodiment, the headlight further includes a dimming assembly for driving the headlight module to rotate. The dimming assembly includes a dimming bolt 7 and a dimming nut 6. The dimming nut 6 is disposed on the headlight module. The dimming bolt 7 passes through the lamp housing 3, and the tail of the dimming bolt 7 is threadedly connected to the dimming nut 6. The lamp housing 3 is provided with a mounting hole for the dimming bolt 7 to pass through. One end of the dimming bolt 7 passes into the interior of the lamp housing 3 and is threadedly connected to the dimming nut 6. By moving the dimming bolt 7 back and forth (relative to the front and rear direction of the vehicle), the dimming nut 6 is driven to move back and forth. Since the headlight module is mounted on the lamp housing 3 through the mounting ear 12, it can rotate about the axis of the mounting ear 12, thereby realizing the change of the headlight beam angle, meeting the functional requirements of the headlight, and facilitating user operation. The matching structure of the dimming bolt 7 and the dimming nut 6 is an application of existing technology and will not be described in detail here.

[0026] In this embodiment, the headlight module also includes a heat sink 5 and a lens 11 disposed on the heat sink 5. Mounting ears 12 are respectively disposed at both lateral ends of the heat sink 5. The shape of the mounting base 301 is adapted to the shape of the mounting ears 12 and can partially accommodate the mounting ears 12. The heat sink 5 is a metal heat sink 5. The mounting ears 12 are disposed at both lateral ends of the heat sink 5. There can be two mounting ears 12, with each mounting ear 12 corresponding to one of the lateral ends of the heat sink 5. Of course, there can also be other numbers of mounting ears 12. Correspondingly, the number of mounting ear limiting members 4 is consistent with the number of mounting ears 12.

[0027] In this embodiment, the dimming assembly further includes a backstop ring 8, which is sleeved on the outer circle of one end of the dimming bolt 7 located inside the lamp housing 3. The backstop ring 8 is provided to prevent the dimming bolt 7 from loosening after adjustment of the dimming bolt 7 and the dimming nut 6, thereby achieving the effect of preventing backstopping.

[0028] The dimming nut 6 is disposed on the heat sink 5; the heat sink 5 is provided with a mounting groove for installing the dimming nut 6. The dimming nut 6 is generally matched with the mounting groove for limiting, so that the overall structure is compact. The matching method between the dimming nut 6 and the heat sink 5 is an application of the prior art, and will not be described in detail here.

[0029] In this embodiment, the dimming assembly further includes a sealing ring 9, which is sleeved on the outer circle of the end of the dimming bolt 7 located inside the lamp housing 3 and positioned between the anti-reverse ring 8 and the inner wall of the lamp housing 3. The sealing ring 9 forms a seal, preventing impurities from entering the headlight.

[0030] In this embodiment, the mounting ear 12 includes an operating handle and a connecting rod. The operating handle is fixedly connected to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to the radiator 5. The mounting base 301 has a groove-shaped structure and can partially wrap around the mounting ear 12. The connecting rod is a circular rod. The mounting ear 12 can be integrally formed with the radiator 5 or welded to the radiator 5, etc. The mounting base 301 can partially wrap around the mounting ear 12, and the shape of the mounting base 301 is adapted to the shape of the mounting ear 12 to facilitate the installation of the mounting ear 12.

[0031] In this embodiment, the mounting ear limiting member 4 is provided with a limiting groove, and the heat sink 5 is provided with a limiting block 13 corresponding to the limiting groove. The limiting block 13 is located within the limiting groove. The mounting ear limiting member 4 has a Z-shaped structure, and the middle part of the mounting ear limiting member 4 protrudes outward to form a limiting cover. The limiting cover is provided above the mounting ear 12, and the shape of the limiting cover is adapted to the shape of the mounting ear 12. During processing, the limiting block 13 can be directly formed on the heat sink 5. At this time, the limiting block 13 can be located above the connecting rod (up and down are relative to the connecting rod). Figure 1 The limiting block 13 can be located on the connecting rod (up and down direction), or it can be located on the connecting rod, which is more conducive to processing and forming. Of course, both methods can be achieved. The limiting groove is opened on the limiting cover. The limiting groove is a U-shaped opening groove. The mounting ear limiting piece 4 is set along the front and rear direction of the vehicle, so that it can span the two sides of the mounting base 301 and cover the mounting ear 12. At this time, the limiting block 13 is located in the limiting groove (there is a gap between it and the limiting groove), so that the adjustment angle of the headlight module during tilt adjustment can be limited, preventing the operator from over-adjusting when manually adjusting, which would cause the lens 11 to collide with the decorative ring of the lens. The limiting cover is partially wrapped around the operating handle. The length of the limiting cover is less than the length of the operating handle, so that the overall installation structure is easy to install.

[0032] The vehicle in this embodiment includes the aforementioned vehicle headlight; the vehicle of this utility model can be an all-terrain vehicle. By changing the installation structure of the radiator 5 and the lamp housing 3, the longitudinal depth of the headlight is reduced, which reduces the risk of fogging inside the headlight while not compressing the safety gap between the mudguard and the tire, thus making it suitable for vehicles with large-size tires.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
