Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more specifically, to an all-terrain vehicle. Background Technology
[0002] All-terrain vehicles are vehicles that can travel on complex terrains such as beaches and grasslands, and are often used in agricultural transportation, outdoor recreation and other scenarios.
[0003] To facilitate driving all-terrain vehicles (ATVs) in low-light conditions, ATVs are generally equipped with headlights, which typically include low beams and high beams spaced apart. In some situations, it's necessary to adjust the position of either the low beam or the high beam to adjust their respective illumination areas. Currently, due to structural limitations, the low beam and high beam are usually adjusted simultaneously; that is, adjusting the position of one of them changes the position of the other concurrently. Therefore, sufficient space must be reserved within the headlight assembly for these position adjustments, resulting in a larger headlight size that can potentially interfere with the installation of other ATV components. Utility Model Content
[0004] In view of this, this application provides an all-terrain vehicle with a smaller headlight size.

The body panels at least partially cover the frame. The running gear is at least partially located below the frame. The power system is at least partially supported by the frame and connected to the running gear for driving the running gear. The lighting system includes a headlight, which includes a lamp housing, a low beam assembly, and a high beam assembly; the lamp housing is connected to the frame, and the low beam assembly and high beam assembly are spaced apart from each other within the lamp housing. Both the low beam assembly and the high beam assembly include a bracket, a light source, and an adjuster; the light source is connected to the bracket, and the adjuster rotatably connects the bracket to the lamp housing, allowing the illumination range of the light source to be adjusted by the adjuster.
[0006] In some embodiments of this application, the adjuster includes a ball head, a ball socket, a first adjusting member, and a second adjusting member; the lamp is connected to the bracket. One of the ball head and the ball socket is connected to the lamp housing, and the other is connected to the bracket, with the ball head and ball socket rotatably engaged. The first adjusting member and the ball head are spaced apart substantially along the width direction of the all-terrain vehicle, and the second adjusting member and the ball head are spaced apart substantially along the height direction of the all-terrain vehicle. Both the first and second adjusting members include an adjusting latch and an adjusting screw; the adjusting latch is rotatably mounted on the bracket, and the adjusting screw is rotatably connected to the lamp housing and threadedly connected to the adjusting latch. The axis passing through the center of the ball head and the rotation center of the adjusting latch of the second adjusting member is defined as the first axis, and the axis passing through the center of the ball head and the rotation center of the adjusting latch of the first adjusting member is defined as the second axis. Rotating the adjusting screw of the first adjusting member causes the bracket to rotate substantially around the first axis, and rotating the adjusting screw of the second adjusting member causes the bracket to rotate substantially around the second axis.
[0007] The lamp housing has a rotating hole, and the adjusting screw has a limiting retaining ring and a limiting protruding ring. The adjusting screw is inserted into the rotating hole, and the limiting retaining ring and the limiting protruding ring respectively clamp the inner and outer sides of the lamp housing; there is a gap between the adjusting screw and the inner wall of the rotating hole for the adjusting screw to swing.
[0008] In some embodiments of this application, the limiting ring includes an annular portion and a plurality of elastic portions spaced circumferentially along the annular portion, the elastic portions being connected to the annular portion; the peripheral wall of the adjusting screw is provided with an abutting ring groove, the annular portion is sleeved on the adjusting screw and abuts against the lamp housing, the elastic portions undergo elastic deformation and abut against the inner wall of the abutting ring groove.
[0009] In some embodiments of this application, the adjusting screw is fitted with an elastic ring, which seals the gap between the adjusting screw and the inner wall of the rotating hole.
[0010] In some embodiments of this application, the lamp housing is provided with a mounting ring groove around the rotating hole, an elastic ring is embedded in the mounting ring groove, the elastic ring abuts against the peripheral wall of the adjusting screw, and a limiting protrusion ring or a limiting stop ring abuts against the elastic ring.
[0011] In some embodiments of this application, a plane perpendicular to the width direction of the all-terrain vehicle and passing through the center of the ball joint is defined as a first reference plane; a plane parallel to the first reference plane and passing through the axis of the adjusting screw of the first adjusting member is defined as a second reference plane; a plane perpendicular to the height direction of the all-terrain vehicle and passing through the center of the ball joint is defined as a third reference plane; and a plane parallel to the third reference plane and passing through the axis of the adjusting screw of the second adjusting member is defined as a fourth reference plane. The distance between the first reference plane and the second reference plane is D1, and the distance between the third reference plane and the fourth reference plane is D2, where D2 is less than D1.
[0012] In some embodiments of this application, both the first and second adjusting components further include an adjusting motor, and the lighting system further includes a controller. The adjusting motor is connected to the lamp housing and is driven by a corresponding adjusting screw. The controller is located in the driver's seat of the all-terrain vehicle and is electrically connected to the adjusting motor to control the rotation of the adjusting motor.
[0013] In some embodiments of this application, the low beam and high beam assemblies are arranged at intervals along the width or height of the all-terrain vehicle.
[0014] In some embodiments of this application, one of the adjusting buckle and the bracket is provided with a snap-fit groove, and the other of the adjusting buckle and the bracket is provided with a snap-fit protrusion. The snap-fit protrusion is inserted into the snap-fit groove, and there is a gap between the snap-fit protrusion and the inner wall of the snap-fit groove so that the adjusting buckle can rotate relative to the bracket.
[0015] In some embodiments of this application, the adjusting buckle includes a mating part and a plurality of snap-fit parts connected to the mating part. The mating part is provided with an adjusting screw hole that is threadedly engaged with the adjusting screw. The plurality of snap-fit parts are arranged around the adjusting screw hole. The snap-fit parts are elastic, and corresponding snap-fit grooves or snap-fit protrusions are provided on the snap-fit parts.
[0016] With the above-described configuration, the headlight provided in this application allows the adjusting screw of the first adjusting member to move the corresponding bracket when the adjusting screw is rotated, causing the bracket to rotate substantially around the first axis, thereby adjusting the illumination area of the lamp along the width direction of the all-terrain vehicle. Similarly, rotating the adjusting screw of the second adjusting member allows the adjusting clip of the second adjusting member to move, causing the bracket to rotate substantially around the second axis, thereby adjusting the illumination area of the lamp along the height direction of the all-terrain vehicle. This all-terrain vehicle headlight allows the low beam assembly bracket and the high beam assembly bracket to rotate independently around their corresponding ball joints to adjust the illumination areas of the low beam and high beam assemblies. This reduces the rotation radius of each bracket, thereby reducing the space required for rotation and ultimately reducing the size of the lamp housing, thus achieving a smaller headlight overall size.

The power supply 152 is a battery, connected to the vehicle frame 11 and electrically connected to the headlights 151 to supply power to them. In some embodiments, the power supply 152 may be a power battery or a generator from the power system.
[0039] Reference Figure 3 and Figure 4 The headlight 151 includes a lamp housing 1511, a low beam assembly 1512, a high beam assembly 1513, and a lamp cover 1514. The lamp housing 1511 is a hollow shell with an opening on one side. The lamp housing 1511 is integrated with the vehicle frame 11 (see...). Figure 1 The connection is made so that the opening of the lamp housing 1511 faces the all-terrain vehicle 100 (see...). Figure 1 The front settings of ).
[0040] The low beam assembly 1512 and the high beam assembly 1513 are disposed substantially spaced apart in the lamp housing 1511 along a left-right direction. Optionally, the high beam assembly 1513 is disposed on the side of the low beam assembly 1512 closest to the center of the width of the all-terrain vehicle 100. In other embodiments, the low beam assembly 1512 and the high beam assembly 1513 may be disposed substantially spaced apart in the vertical direction along a vertical direction. In other embodiments, the low beam assembly 1512 and the high beam assembly 1513 may also be disposed substantially spaced apart in a direction inclined relative to the left-right direction.
[0041] Reference Figure 2 and Figure 4 The low beam headlight assembly 1512 includes a bracket 1512a, a lamp 1512b, and an adjuster 1512h. The adjuster 1512h includes a ball joint 1512c, a ball socket 1512d, a first adjusting member 1512e, and a second adjusting member 1512f. The high beam headlight assembly 1513 also includes a bracket 1512a, a lamp 1512b, a ball joint 1512c, a ball socket 1512d, a first adjusting member 1512e, and a second adjusting member 1512f. The high beam headlight assembly 1513 has the same structure as the low beam headlight assembly 1512 described above. The following description uses the low beam headlight assembly 1512 as an example; the high beam headlight assembly 1513 will not be further elaborated.
[0042] The bracket 1512a is located inside the lamp housing 1511; the lamp 1512b is connected to the bracket 1512a and electrically connected to the power supply 152. The lighting system 15 also includes a control unit 153, a high beam switch 154, and a low beam switch 155. The power supply 152, the high beam switch 154, the low beam switch 155, and the lamp 1512b are all electrically connected to the control unit 153 so that the lamp 1512b is electrically connected to the power supply 152. Optionally, the control unit 153 is an ECU (Electronic Control Unit). It is understood that the low beam switch 155 is used to control the lamp 1512b of the low beam assembly 1512 to be powered on or off, and the high beam switch is used to control the lamp 1512b of the high beam assembly 1513 to be powered on or off. In some other embodiments, the control element 153 may be omitted, and the light 1512b is connected to the power supply 152 via a low beam switch 155 or a high beam switch 154. As long as the low beam switch 155 can control the light 1512b of the low beam assembly 1512 to be powered on or off, and the high beam switch can control the light 1512b of the high beam assembly 1513 to be powered on or off, it is acceptable.
[0043] One of the ball head 1512c and the ball socket 1512d is connected to the lamp housing 1511, and the other of the ball head 1512c and the ball socket 1512d is connected to the bracket 1512a. The ball head 1512c and the ball socket 1512d are rotatably engaged. Optionally, the ball head 1512c is provided with a connecting stud 1512g, and the inner wall of the lamp housing 1511 is provided with a connecting threaded sleeve 1511a. The connecting stud 1512g and the connecting threaded sleeve 1511a are threadedly connected, so that the ball head 1512c is connected to the lamp housing 1511; the ball socket 1512d and the bracket 1512a are integrally injection molded.
[0044] The first adjusting member 1512e and the ball head 1512c are basically spaced apart in the left-right direction, and the second adjusting member 1512f and the ball head 1512c are basically spaced apart in the up-down direction. Both the first adjusting member 1512e and the second adjusting member 1512f include an adjusting buckle 1512j and an adjusting screw 1512k; the adjusting buckle 1512j is rotatably mounted on the bracket 1512a, the adjusting screw 1512k is rotatably connected to the lamp housing 1511 and threadedly connected to the adjusting buckle 1512j, and the axis of the adjusting screw 1512k is basically arranged in the front-back direction.
[0045] The axis passing through the center of the ball head 1512c and the rotation center of the adjusting latch 1512j of the second adjusting member 1512f is defined as the first axis 101, and the axis passing through the center of the ball head 1512c and the rotation center of the adjusting latch 1512j of the first adjusting member 1512e is defined as the second axis 102. When the adjusting screw 1512k of the first adjusting member 1512e is rotated, the adjusting latch 1512j of the first adjusting member 1512e can drive the corresponding bracket 1512a to move, so that the bracket 1512a rotates substantially around the first axis 101 to adjust the illumination area of the light lamp 1512b in the left-right direction; when the adjusting screw 1512k of the second adjusting member 1512f is rotated, the adjusting latch 1512j of the second adjusting member 1512f can move, so that the bracket 1512a rotates substantially around the second axis 102 to adjust the illumination area of the light lamp 1512b in the up-down direction.
[0046] In some embodiments, the first adjusting member 1512e and the second adjusting member 1512f both include an adjusting motor 1512m, and the lighting system 15 also includes a controller 156. The adjusting motor 1512m is connected to the lamp housing 1511 and electrically connected to the control member 153 for electrical connection to the power supply 152. The adjusting motor 1512m is connected to a corresponding adjusting screw 1512k; optionally, the output shaft of the adjusting motor 1512m is coaxially and fixedly connected to the adjusting screw 1512k. The controller 156 is a knob-driven connection, and the controller 156 is located on the all-terrain vehicle 100 (see...). Figure 1 Driver's seat 121 (see) Figure 1 It is electrically connected to the control unit 153 to control the rotation of the regulating motor 1512m.
[0047] Alternatively, two controllers 156 are provided: one controller 156 for controlling the adjusting motor 1512m of the first adjusting member 1512e, and the other controller 156 for controlling the adjusting motor 1512m of the second adjusting member 1512f. The driver can control the adjusting motor 1512m from the driver's seat 121 via the controller 156, improving the convenience of adjusting the headlight 151. In other embodiments, the controller 156 may be a physical button, a virtual button on a touchscreen, or other device capable of adjusting the forward or reverse rotation of the motor 1512m.
[0048] Reference Figure 4 and Figure 5 The lampshade 1514 is disposed over the opening of the lamp housing 1511 and connected to the lamp housing 1511. It is understood that the lampshade 1514 is transparent so that the light from the lamp 1512b can pass through the lampshade 1514, and the lampshade 1514 has a protective effect on the lamp 1512b.
[0049] Reference Figure 6 and Figure 7One of the adjusting buckle 1512j and the bracket 1512a is provided with a snap-fit groove 1512p, and the other of the adjusting buckle 1512j and the bracket 1512a is provided with a snap-fit protrusion 1512n. The snap-fit protrusion 1512n is inserted into the snap-fit groove 1512p, and there is a gap between the snap-fit protrusion 1512n and the inner wall of the snap-fit groove 1512p, so that the adjusting buckle 1512j can rotate relative to the bracket 1512a.
[0050] Alternatively, the bracket 1512a is provided with a snap-fit protrusion 1512n, which is annular; the adjusting buckle 1512j includes a mating part 1512q and multiple snap-fit parts 1512r. The mating part 1512q is provided with an adjusting screw hole 1512s that is threadedly engaged with the adjusting screw 1512k. The snap-fit parts 1512r are basically rod-shaped. Multiple snap-fit parts 1512r are arranged around the adjusting screw hole 1512s and connected to the mating part 1512q. The snap-fit parts 1512r are provided with snap-fit grooves 1512p. The snap-fit portion 1512r is elastic; when installing the adjusting buckle 1512j, multiple snap-fit portions 1512r can be bent toward the axis of the adjusting screw hole 1512s to insert multiple snap-fit portions 1512r into the interior of the annular snap-fit protrusion 1512n. Then, by releasing the snap-fit portion 1512r, the snap-fit protrusion 1512n can be snapped into the snap-fit groove 1512p. It is understood that the width of the snap-fit groove 1512p is greater than the thickness of the annular snap-fit protrusion 1512n. Exemplarily, two snap-fit portions 1512r are symmetrically provided.
[0051] In other embodiments, the snap-fit protrusion 1512n may be block-shaped, and multiple snap-fit protrusions 1512n are provided in a one-to-one correspondence with the snap-fit portion 1512r, with each snap-fit protrusion 1512n inserted into the snap-fit groove 1512p of the corresponding snap-fit portion 1512r.
[0052] In other embodiments, the adjusting latch 1512j may be ball-hinged with the bracket 1512a so that the adjusting latch 1512j can rotate relative to the bracket 1512a.
[0053] The lamp housing 1511 has a rotating hole 1511b, and the adjusting screw 1512k has a limiting protrusion ring 1512t and a limiting retaining ring 1512v. The adjusting screw 1512k is inserted into the rotating hole 1511b, and the limiting retaining ring 1512v and the limiting protrusion ring 1512t respectively clamp the inner and outer sides of the lamp housing 1511. Optionally, the limiting retaining ring 1512v is located inside the lamp housing 1511, and the limiting protrusion ring 1512t is located outside the lamp housing 1511. The limiting protrusion ring 1512t is the head of the adjusting screw 1512k, and the limiting protrusion ring 1512t and the adjusting screw 1512k are integrally formed; the limiting retaining ring 1512v and the adjusting screw 1512k are detachably connected. A gap is provided between the adjusting screw 1512k and the inner wall of the rotating hole 1511b to allow the adjusting screw 1512k to swing, so that the adjusting screw 1512k can swing with the rotation of the bracket 1512a, thereby reducing the risk of jamming between the adjusting buckle 1512j and the adjusting screw 1512k.
[0054] The limiting ring 1512v includes an annular portion 1512w and several elastic portions 1512x spaced circumferentially along the annular portion 1512w. The annular portion 1512w is a closed ring, and the elastic portions 1512x are sheet-like, connected to the annular portion 1512w. The peripheral wall of the adjusting screw 1512k is provided with an abutting ring groove. The annular portion 1512w is sleeved on the adjusting screw 1512k, and the elastic portions 1512x are inserted into the abutting ring groove. The annular portion 1512w abuts against the inner wall of the lamp housing 1511, and the elastic portions 1512x abut against the inner wall of the abutting ring groove. The elastic portions 1512x are in an elastically deformed state, causing the limiting protrusion 1512t to abut against the outer shell of the lamp housing 1511. When the adjusting screw 1512k swings, the elastic part 1512x deforms, so that the adjusting limit convex ring 1512t and the lamp housing 1511 always remain in contact, thereby fixing the adjusting screw 1512k relative to the lamp housing 1511, so that the rotating bracket 1512a remains fixed.
[0055] In some embodiments, the adjusting screw 1512k is fitted with an elastic ring 1512y, and the lamp housing 1511 is provided with a mounting ring groove 1511c around the rotating hole 1511b. The elastic ring 1512y is embedded in the mounting ring groove 1511c and abuts against the peripheral wall of the adjusting screw 1512k, so that the elastic ring 1512y seals the gap between the adjusting screw 1512k and the inner wall of the rotating hole 1511b, which can improve the sealing performance of the lamp housing 1511 and reduce the risk of dust, moisture and other substances entering the interior of the lamp housing 1511 through the rotating hole 1511b.
[0056] Alternatively, the mounting groove 1511c is provided on the outer wall of the lamp housing 1511, and the limiting protrusion 1512t abuts against the elastic ring 1512y. In other embodiments, the mounting groove 1511c may be provided on the inner wall of the rotating hole 1511b.
[0057] In some embodiments, the limiting retaining ring 1512v can be a spring retaining ring, and the distance between the limiting retaining ring 1512v and the limiting protrusion ring 1512t is greater than the thickness of the lamp housing 1511. The elastic ring 1512y can fill the gap between the adjusting screw 1512k and the inner wall of the rotating hole 1511b; after the adjusting screw 1512k swings, the elastic ring 1512y undergoes elastic deformation, at which time the elastic ring 1512y can support the adjusting screw 1512k, so that the adjusting screw 1512k is fixed relative to the lamp housing 1511, thereby allowing the adjusting screw 1512k to maintain its swing posture.
[0058] In other embodiments, the adjusting screw 1512k can rotatably engage with the rotating hole 1511b, with the peripheral wall of the adjusting screw 1512k fitting against the inner peripheral wall of the rotating hole 1511b, and the bracket 1512a being elastic. When the bracket 1512a rotates to a certain position, it can undergo elastic deformation to reduce the risk of jamming between the adjusting latch 1512j and the adjusting screw 1512k.
[0059] Reference Figure 8 When the bracket 1512a rotates around the first axis 101, the rotation radius of the high beam assembly 1513's lamp 1512b is R1, and the rotation radius of the low beam assembly 1512's lamp 1512b is R2. When the bracket 1512a rotates around the first axis 101 by the maximum preset angle α, the distance L1 by which the high beam assembly 1513's lamp 1512b deviates from its initial position in the front-back direction is the product of R1 and sinα, and the distance L2 by which the low beam assembly 1512's lamp 1512b deviates from its initial position in the front-back direction is the product of R2 and sinα. Here, sin is a sine function. It can be understood that the interior of the lamp housing 1511 needs to reserve at least twice the maximum value of L1 and L2 in the front-back direction.
[0060] Reference Figure 9In an existing adjustable headlight 200, the low beam 21 and high beam 22 are generally spaced apart along the left-right direction on the same adjustment frame 23. The adjustment frame 23 is rotatably connected to a conventional lamp housing 24. The low beam 21 is located on the side of the high beam 22 away from the rotation center of the adjustment frame 23. When the adjustment frame 23 is rotated, the low beam 21 and high beam 22 rotate synchronously with the adjustment frame 23. For example, when the adjustment frame 23 is rotated to adjust the illumination area of the low beam 21 or high beam 22 along the left-right direction, the rotation radius of the high beam 22 is R1, and the rotation radius of the low beam 21 is R3. When the adjustment frame 23 rotates to the maximum preset angle α, the distance L1 by which the high beam 22 deviates from its initial position along the front-back direction is the product of R1 and sinα, and the distance L3 by which the low beam 21 deviates from its initial position along the front-back direction is the product of R3 and sinα. Understandably, the interior of a standard lamp housing 24 needs to have at least twice the size of L3 reserved along the front-to-back direction. Figure 9 The rectangular dashed box in the figure represents the lamp housing 1511 of the headlight 151 of this application.
[0061] Reference Figure 8 and Figure 9 By rotatably connecting the bracket 1512a of the low beam assembly 1512 and the bracket 1512a of the high beam assembly 1513 to the lamp housing 1511, and by individually adjusting the positions of the brackets 1512a of the low beam assembly 1512 and the high beam assembly 1513, L1 and L2 can both be made smaller than L3. This reduces the space required to be reserved in the front-rear direction inside the lamp housing 1511, thereby reducing the volume of the lamp housing 1511 and the overall volume of the headlight 151, thus reducing the impact of the headlight 151 on the all-terrain vehicle 100 (see...). Figure 1 The installation of other components can affect the overall appearance of the vehicle and enhance its competitiveness.
[0062] Reference Figure 10 A plane perpendicular to the left-right direction and passing through the center of the ball head 1512c is defined as the first reference plane 103. A plane parallel to the first reference plane 103 and passing through the axis of the adjusting screw 1512k of the first adjusting member 1512e is defined as the second reference plane 104. A plane perpendicular to the up-down direction and passing through the center of the ball head 1512c is defined as the third reference plane 105. A plane parallel to the third reference plane 105 and passing through the axis of the adjusting screw 1512k of the second adjusting member 1512f is defined as the fourth reference plane 106. The distance between the first reference plane 103 and the second reference plane 104 is D1, and the distance between the third reference plane 105 and the fourth reference plane 106 is D2, where D2 is less than D1. In the figure, the first axis 101 coincides with the first reference plane 103, and the second axis 102 coincides with the third reference plane 105.
[0063] By making D2 smaller than D1, the internal space of the lamp housing 1511 can be increased without expanding the bracket 1512a (see Figure 4 The range of rotation around the second axis 102 is greater than the range of rotation of the bracket 1512a around the first axis 101, so that the illumination area of the lamp 1512b has a greater range of adjustment in the vertical direction, thereby enabling the headlight 151 to shine farther.

Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
