Description

Technical Field

[0001] This application relates to the field of vehicle lighting, and in particular to a lens position adjustment device and a vehicle lamp. Background Technology

[0002] The lens module assembly of automotive headlights needs to have both vertical and horizontal adjustment functions.

[0003] In the prior art, the dimming device includes three ball heads with their centers on the same plane, and the three ball heads are respectively arranged at the three vertices of a right triangle. One ball head is located at the right vertex and serves as the reference point for adjustment. The other two ball heads are respectively arranged on two axes that start from the reference point and extend in the vertical and horizontal directions, thus forming a left-right adjustment rotation axis and a right-up adjustment rotation axis.

[0004] For stability reasons, the dimming device used to support and adjust the lens module assembly needs to be close to the center of gravity of the lens module assembly. Since the center of gravity of the lens module assembly is located slightly rear-centrally, the front end of the lens module assembly is relatively far from the dimming device. Therefore, when adjusting the lens module assembly, the front end swings significantly, requiring the trim frame to have a large opening to accommodate the swing range. However, an excessively large opening in the trim frame makes the internal components visible, affecting the overall aesthetics of the lamp. Summary of the Invention

[0005] The purpose of this application is to provide a lens position adjustment device and a vehicle lamp that can reduce the swing amplitude of the outer lens and avoid the problem that the internal components are visible due to the excessively large hole in the trim frame, which affects the aesthetics of the entire lamp.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

[0048] Example 1

[0049] See Figures 1 to 6 As shown, the lens position adjustment device provided in this application is used for vehicle lights. It can be used to adjust the position of the outer lens 102 of the lens module assembly 101 of the vehicle light vertically and horizontally. Figure 1 As shown, the lens module assembly 101 also includes a housing 103 and a heat sink 104. The outer lens 102 is mounted on the front end of the housing 103, and the heat sink 104 is mounted on the rear end of the housing 103 (with the light output direction of the headlight as the front and the opposite direction of the light output direction as the rear).

[0050] Specifically, the lens position adjustment device includes a fixed bracket 105 and an adjustment mechanism 106. The adjustment mechanism 106 is used to connect to the lens module assembly 101 to support the lens module, and the connection position is close to the center of gravity of the lens module assembly 101 to ensure the stability of the support.

[0051] The fixed bracket 105 is connected to the lamp housing 110 of the vehicle lamp. The fixed bracket 105 is provided with a preset spherical surface 107. The adjustment mechanism 106 is installed on the fixed bracket 105. Under the action of external force, the adjustment mechanism 106 can move along the preset spherical surface 107. The movement path of the lens module assembly 101 is located on the preset spherical surface 107. No matter the swing direction of the lens module assembly 101, the swing center of the lens module assembly 101 is always the center of the preset spherical surface 107. By setting the center of the preset spherical surface 107 between the outer lens 102 of the lens module assembly 101 and the connection position, the rotation radius of the outer lens 102 is reduced. For the same swing angle, the outer lens 102 with a smaller rotation radius has a smaller swing amplitude.

[0052] The lens position adjustment device provided in this application can reduce the rotation radius of the outer lens 102 of the lens module assembly 101, thereby reducing the swing amplitude of the outer lens 102, avoiding the internal components being visible due to excessively large holes in the frame, and improving the overall aesthetics of the lamp.

[0053] It should be noted that, due to the omnidirectional structure of the spherical surface, the movement direction of the adjustment mechanism 106 is not limited. The position of the lens module assembly 101 can also be adjusted in other directions except for the up and down and left and right directions, making the device more adaptable.

[0054] Preferably, the light-emitting surface of the outer lens 102 is a spherical surface, and the spherical surface of the light-emitting surface is concentric with the preset spherical surface 107. That is to say, no matter how the outer lens 102 swings, the light-emitting surface of the outer lens 102 is always located on the same spherical surface, without changing its optical characteristics.

[0055] In an optional embodiment, the adjustment mechanism 106 includes an adjustment frame body connected to the lens module assembly 101 and at least three ball heads. The adjustment frame body is fitted onto the center of gravity of the lens module assembly 101, and the adjustment frame body is connected to the lens module assembly 101 to ensure stable support of the lens module assembly 101 by the adjustment frame body. The multiple ball heads are spaced apart around the circumference of the adjustment frame body, forming multiple non-collinear contact points, so that the relative distance between the adjustment frame body and the preset spherical surface 107 remains unchanged when the adjustment frame body moves along the preset spherical surface 107, and will not collide with the fixed bracket 105.

[0056] The preset spherical surface 107 includes multiple spherical surfaces that are respectively set to correspond to multiple ball heads, and the ball heads slide on the corresponding spherical surfaces, which can reduce the frictional force of movement, so as to make the adjustment process of the lens module assembly 101 smoother.

[0057] More specifically, the fixed bracket 105 includes a fixed frame 108 and multiple support legs 109, with the fixed frame 108 fixed to the lamp housing 110 via the multiple support legs 109. The main body of the adjustment bracket extends through the inner circle of the fixed frame 108, so that multiple ball heads in the circumferential direction of the adjustment bracket main body can contact the multiple spherical surfaces correspondingly provided on the fixed frame 108.

[0058] In an optional embodiment, the main body of the adjustment frame includes a first adjustment frame 111 and a second adjustment frame 112, which are connected to each other so that the lens module assembly 101 passes through the first adjustment frame 111 and the second adjustment frame 112 in sequence.

[0059] See Figure 3 and Figure 4 As shown, the plurality of ball heads includes three first ball heads 113 and three second ball heads 114. The three first ball heads 113 are located on the front side of the fixed frame 108 and are spaced apart around the first adjusting frame 111. The three second ball heads 114 are located on the rear side of the fixed frame 108 and are spaced apart around the second adjusting frame 112. The plurality of spherical surfaces includes three first spherical surfaces 115 and three second spherical surfaces 116. The front side of the fixed frame 108 is provided with three first spherical surfaces 115 corresponding to the three first ball heads 113, and the rear side of the fixed frame 108 is provided with three second spherical surfaces 116 corresponding to the three second ball heads 114. The first spherical surfaces 115 and the second spherical surfaces 116 are concentric.

[0060] The positions of the first spherical surface 115 and the second spherical surface 116 correspond one-to-one, and the first ball head 113 and the second ball head 114, which slide on the two surfaces respectively, are also correspondingly arranged one-to-one. One of the first ball heads 113 shown in the figure is located on the vertical center line and forms an isosceles triangle structure with the other two ball heads. The arrangement of the second ball head 114 is the same. The first ball head 113 and the second ball head 114 are spaced a predetermined distance apart to clamp the fixing frame 108 between them. This achieves the function of mounting the adjustment mechanism 106 on the fixing bracket 105 without affecting the movement of the adjustment mechanism 106 relative to the fixing bracket 105.

[0061] Example 2

[0062] The lens position adjustment device in this embodiment is an improvement on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this embodiment.

[0063] In an optional embodiment, the lens position adjustment device further includes a first driving mechanism 117; the first driving mechanism 117 includes a first driving component, which outputs a first driving force in a first direction; the first driving force has at least a component in a first preset direction to drive the adjustment mechanism 106 to move on the preset spherical surface 107 along the first preset direction; the first preset direction is the first preset tangent direction of the spherical surface at the point where the first driving force is applied, and the first preset tangent is located in a vertical plane.

[0064] In this embodiment, to achieve the up-and-down adjustment function of the external lens 102, the direction of the first driving force needs to meet the following condition: that is, the force applied by the first driving component to the adjustment mechanism 106 enables the adjustment mechanism 106 to move up and down along the preset spherical surface 107. Specifically, when the adjustment mechanism 106 moves on the preset spherical surface 107, at the point of force application between the adjustment mechanism 106 and the preset spherical surface 107, the pressure exerted by the adjustment mechanism 106 on the preset spherical surface 107 is decomposed into a force in the first preset tangential direction and a force in the normal direction, and the force in the first preset tangential direction is located in the vertical plane, so that the adjustment mechanism 106 can move up and down along the preset spherical surface 107.

[0065] In an optional embodiment, the lens module assembly 101 can form a lever structure with the center of a preset spherical surface 107 as the fulcrum on a vertical plane. A first driving force is applied as a power to one end of the lever structure, and the first driving force is a force in the vertical direction.

[0066] Specifically, see Figure 4 As shown, the first drive assembly includes a first drive device 118 and a transmission ball head 119. The first drive device 118 is specifically an electric regulator, and the first drive device 118 is connected to the transmission ball head 119 to drive the transmission ball head 119 to reciprocate linearly in the vertical direction.

[0067] The first drive assembly is located above the adjustment mechanism 106 to drive the adjustment mechanism 106 to move up and down along the preset spherical surface 107. Since the adjustment mechanism 106 undergoes displacement in both the vertical and horizontal directions as it moves up and down along the preset spherical surface 107, the first drive assembly needs to be movably connected to the adjustment mechanism 106 in the forward and backward directions. The guide groove 120 provided in the first drive mechanism 117 provides the forward and backward movement path, enabling the adjustment mechanism 106 to move back and forth relative to the first drive assembly.

[0068] Specifically, the guide groove 120 is connected to the adjustment mechanism 106, and the guiding direction of the guide groove 120 is the illumination direction (i.e., the front-to-back direction) of the lens module assembly 101. The transmission ball head 119 is placed in the guide groove 120 and can slide relative to the guide groove 120. During the movement of the transmission ball head 119, the transmission ball head 119 can always be engaged at the groove opening of the guide groove 120. When the first driving device 118 drives the transmission ball head 119 to reciprocate in the vertical direction, the transmission ball head 119 will not disengage from the guide groove 120, thus ensuring that the first driving assembly is fixedly connected to the adjustment mechanism 106 in the vertical direction.

[0069] Optionally, the first driving force can also be a horizontal force. This horizontal force can be decomposed to create a force that drives the adjustment mechanism 106 to move up and down along the preset spherical surface 107, and adaptively changes the direction of the guide groove 120. The principle is the same as the above-described scheme and will not be repeated here.

[0070] In a specific implementation, compared to the first driving force in the horizontal direction, the first driving force in the vertical direction has a smaller angle with the preset spherical surface 107, resulting in a larger decomposed force for the driving adjustment mechanism 106 to move along the preset spherical surface 107, and making it easier for the driving adjustment mechanism 106 to move.

[0071] In an optional embodiment, the lens position adjustment device further includes a second driving mechanism 121; the second driving mechanism 121 outputs a second driving force in a second direction, the second driving force having at least a component in a second preset direction, to drive the adjustment mechanism 106 to move along the second preset direction on the preset spherical surface 107; the second preset direction is the second preset tangent direction of the spherical surface at the point where the second driving force is applied, and the second preset tangent is located in a horizontal plane.

[0072] In this embodiment, to achieve the left-right adjustment function of the external lens 102, the direction of the second driving force needs to meet the following condition: that is, the force applied by the second driving component to the adjustment mechanism 106 enables the adjustment mechanism 106 to move left and right along the preset spherical surface 107. Specifically, when the adjustment mechanism 106 moves on the preset spherical surface 107, at the point of force application between the adjustment mechanism 106 and the preset spherical surface 107, the pressure exerted by the adjustment mechanism 106 on the preset spherical surface 107 is decomposed into a force in the second preset tangential direction and a force in the normal direction, and the force in the second preset tangential direction is located on the horizontal plane, so that the adjustment mechanism 106 can move left and right along the preset spherical surface 107.

[0073] In an optional embodiment, the lens module assembly 101 can also form a lever structure with the center of the preset spherical surface 107 as the fulcrum on the horizontal plane. The second driving force is applied as a power to one end of the lever structure, and the second driving force is a force in the left-right direction of the lens module assembly 101.

[0074] Specifically, see Figure 1 , Figure 5 and Figure 6 As shown, the second drive mechanism 121 is located behind the lens module assembly 101 and provides a second driving force in the left-right direction. The second drive mechanism 121 includes a second drive assembly, a drive groove 122, and a drive rod 123. The second drive assembly includes a second drive device that outputs driving force and a bevel gear 124, an adjusting screw 125, and a locking buckle 126 that sequentially transmit driving force. A fixing frame 127 is mounted on the lamp housing 110. The bevel gear 124, the adjusting screw 125, and the locking buckle 126 are all mounted on the fixing frame 127, and the fixing frame 127 is provided with a slide rail. The drive groove 122 is installed in the slide rail. The second drive device drives the bevel gear 124 to rotate, and the adjusting screw 125 rotates through gear meshing. The rotational motion is converted into linear motion by the locking buckle 126, which is threadedly connected to the adjusting screw 125, so as to drive the drive groove 122 connected to the locking buckle 126 to move left and right.

[0075] The second drive assembly is connected to the drive groove 122 to drive the drive groove 122 to reciprocate linearly along a second preset direction (the guide direction of the slide rail). The second preset direction is located on a horizontal plane and is perpendicular to the light emission direction of the lens module assembly 101 (i.e., the left-right direction of the lens module assembly 101). One end of the drive rod 123 is connected to the tail end of the lens module assembly 101, and the other end of the drive rod 123 is placed in the drive groove 122, and the inner surface of the drive groove 122 is an arc surface that drives the drive rod 123 to swing.

[0076] In this embodiment, when the drive groove 122 moves left and right, the inner surface of the drive groove 122 applies force to the end of the drive rod 123, causing the outer lens 102 at the front end of the lens module assembly 101 to swing left and right, and the swing direction of the outer lens 102 is opposite to the swing direction of the drive rod 123. The swing path of the drive rod 123 is an arc path, so the inner surface of the drive groove 122 is set as an arc surface to ensure that the drive groove 122 can always contact the drive rod 123, and the depth of the drive rod 123 extending into the drive groove 122 can ensure that the drive rod 123 will not separate from the drive groove 122 during the swing.

[0077] Optionally, in a scheme that integrates the first drive mechanism 117 and the second drive mechanism 121, the connection relationship between the integrated adjustment bracket and lens module assembly 101 and the two drive mechanisms needs to be considered.

[0078] See Figure 1 and Figure 5 As shown, during the operation of the first drive mechanism 117, the adjusting bracket drives the lens module assembly 101 to swing up and down. At this time, the position of the second drive mechanism 121 remains unchanged. Therefore, the drive groove 122 is set as a long strip groove structure with a vertical movement path so that the drive rod 123 swinging up and down has movement space. The two ends of the drive groove 122 in the vertical direction are also set as arc surfaces to match the movement path of the drive rod 123.

[0079] See Figure 1 and Figure 4 As shown, during the operation of the second drive mechanism 121, the lens module assembly 101 drives the adjustment bracket to swing left and right. At this time, the position of the first drive mechanism 117 remains unchanged, so the guide slide 120 is movably mounted on the adjustment mechanism 106. Specifically, the adjustment mechanism 106 has an elongated hole 128 with a left-right movement path, and the guide slide 120 is movably mounted in the elongated hole 128, so that the adjustment mechanism 106 can move left and right relative to the guide slide 120, thus realizing the left-right adjustment function of the lens module assembly 101.
