Example 1

Referring to fig. 1 to 6, the lens position adjusting device provided by the present application is used for a vehicle lamp. Can be used for up-and-down adjustment and left-and-right adjustment of the position of the outer lens 102 of the lens module assembly 101 of the car lamp.

Specifically, the lens position adjustment device includes a fixed bracket 105 and an adjustment mechanism 106. The adjusting mechanism 106 is used for connecting the lens module assembly 101 to play a role in supporting the lens module, and the connecting position is close to the center of gravity of the lens module assembly 101, so that the stability of the support can be ensured.

The fixed support 105 is connected with the lamp housing 110 of the car lamp, the fixed support 105 is provided with a preset spherical surface 107, the adjusting mechanism 106 is installed on the fixed support 105, the adjusting mechanism 106 can move along the preset spherical surface 107 under the action of external force, the moving path of the lens module assembly 101 is located on the preset spherical surface 107, and the swinging center of the lens module assembly 101 is always the sphere center of the preset spherical surface 107 no matter the swinging direction of the lens module assembly 101. The center of the preset spherical surface 107 is arranged between the outer lens 102 of the lens module assembly 101 and the connecting position, so that the rotation radius of the outer lens 102 is reduced, the same swing angle is adopted, and the swing amplitude of the outer lens 102 with smaller rotation radius is smaller.

The lens position adjusting device provided by the application can reduce the rotation radius of the outer lens 102 of the lens module assembly 101 so as to reduce the swing amplitude of the outer lens 102, avoid the internal components from being visible due to overlarge holes formed in the decorative frame, and improve the attractiveness of the whole lamp.

The universal structure of the spherical surface does not limit the movement direction of the adjusting mechanism 106, and the lens module assembly 101 can be adjusted in the directions except the up-down direction and the left-right direction according to the actual situation, so that the device has wider adaptability.

Preferably, the light emitting surface of the outer lens 102 is a spherical surface, and the spherical surface of the light emitting surface and the preset spherical surface 107 are concentric, that is, the light emitting surface of the outer lens 102 is always located on the same spherical surface regardless of the swing of the outer lens 102, without changing the optical characteristics thereof.

In an alternative to this embodiment, the adjustment mechanism 106 includes an adjustment bracket body and at least three balls connected. The adjusting frame body is sleeved at the center of gravity of the lens module assembly 101 and is connected with the lens module assembly 101, so that the adjusting frame body can be ensured to stably support the lens module assembly 101. The plurality of ball heads are arranged at intervals in the circumferential direction of the adjusting frame body to form a plurality of contact points which are not collinear, so that the relative distance between the adjusting frame body and the preset spherical surface 107 is kept unchanged when the adjusting frame body moves along the preset spherical surface 107, and the adjusting frame body cannot collide with the fixed support 105.

The preset spherical surface 107 includes a plurality of spherical surface portions respectively corresponding to the plurality of spherical heads, and the spherical heads slide on the corresponding spherical surface portions, so that the movement friction force can be reduced, and the adjustment process of the lens module assembly 101 is smoother.

More specifically, the fixing bracket 105 includes a fixing frame 108 and a plurality of legs 109, and the fixing frame 108 is fixed to the lamp housing 110 by the plurality of legs 109. The adjusting frame body penetrates through the inner ring of the fixed frame 108, so that a plurality of spherical heads in the circumferential direction of the adjusting frame body can be contacted with a plurality of spherical parts correspondingly arranged on the fixed frame 108.

In an alternative solution of this embodiment, specifically, the adjusting frame body includes a first adjusting frame 111 and a second adjusting frame 112, where the first adjusting frame 111 and the second adjusting frame 112 are correspondingly connected, so that the lens module assembly 101 sequentially penetrates through the first adjusting frame 111 and the second adjusting frame 112.

Referring to fig. 3 and 4, the plurality of balls includes three first balls 113 and three second balls 114.

Example two

The lens position adjustment device in the second embodiment is an improvement on the above embodiment, and the technical content disclosed in the above embodiment is not repeated, and the content disclosed in the above embodiment also belongs to the content disclosed in the second embodiment.

In an alternative to this embodiment, the lens position adjustment device further comprises a first drive mechanism 117; the first driving mechanism 117 includes a first driving assembly that 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 in the first preset direction on the preset spherical surface 107; the first preset direction is a first preset tangent direction of the spherical surface at the application point acted by the first driving force, and the first preset tangent is positioned on the vertical plane.

In this embodiment, in order to realize the up-down adjustment function of the external lens 102, the direction of the first driving force needs to satisfy the following conditions: i.e. the force exerted by the first drive assembly on the adjustment mechanism 106, enables the adjustment mechanism 106 to move up and down along the preset sphere 107. Specifically, when the adjustment mechanism 106 moves on the preset spherical surface 107, at the point of application between the adjustment mechanism 106 and the preset spherical surface 107, the pressure of the adjustment mechanism 106 acting 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 on the vertical plane, so that the adjustment mechanism 106 can be moved up and down along the preset spherical surface 107.

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

Specifically, referring to fig. 4, the first driving assembly includes a first driving device 118 and a driving ball 119, the first driving device 118 is specifically an electric regulator, and the first driving device 118 is connected with the driving ball 119 to drive the driving ball 119 to reciprocate in a straight line in a vertical direction.

The first driving component is located above the adjusting mechanism 106 to drive the adjusting mechanism 106 to move up and down along the preset spherical surface 107. Since the adjustment mechanism 106 is displaced in the front direction in addition to the displacement in the up-down direction when the adjustment mechanism 106 moves up and down along the preset spherical surface 107, the first driving assembly needs to be movably connected to the adjustment mechanism 106 in the front-rear direction. The guide chute 120 provided by the first drive mechanism 117 provides a fore-aft movement path to enable fore-aft movement of the adjustment mechanism 106 relative to the first drive assembly.

Specifically, the guiding chute 120 is connected to the adjusting mechanism 106, and the guiding direction of the guiding chute 120 is the illumination direction (i.e. the front-rear direction) of the lens module assembly 101. The drive ball 119 is disposed within the guide chute 120 and is capable of sliding relative to the guide chute 120. In the process of the movement of the transmission ball 119, the transmission ball 119 can be always clamped at the notch of the guide chute 120, and when the first driving device 118 drives the transmission ball 119 to reciprocate along the vertical direction, the transmission ball 119 cannot be separated from the guide chute 120, so that the first driving component is fixedly connected with the adjusting mechanism 106 in the vertical direction.

Alternatively, the first driving force may be a force in a horizontal direction, and only the force in the horizontal direction needs to be decomposed to form a force for driving the adjusting mechanism 106 to move up and down along the preset spherical surface 107, and the direction of the guiding chute 120 is adaptively changed. The principle is the same as that of the scheme, and the description is omitted here.

In a specific embodiment, the first driving force in the vertical direction has a smaller included angle with the preset spherical surface 107 than the first driving force in the horizontal direction, so that the resolution of the movement of the driving adjustment mechanism 106 along the preset spherical surface 107 is greater, and the movement of the driving adjustment mechanism 106 is easier.

In an alternative of this embodiment, the lens position adjustment device further comprises a second drive 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 in the second preset direction at the preset spherical surface 107; the second preset direction is a second preset tangent direction of the spherical surface at the application point acted by the second driving force, and the second preset tangent is positioned on the horizontal plane.

In this embodiment, in order to realize the left-right adjustment function of the external lens 102, the direction of the second driving force needs to satisfy the following conditions: i.e. the force exerted by the second drive assembly on the adjustment mechanism 106, enables the adjustment mechanism 106 to move left and right along the preset sphere 107. Specifically, when the adjustment mechanism 106 moves on the preset spherical surface 107, at the point of application between the adjustment mechanism 106 and the preset spherical surface 107, the pressure of the adjustment mechanism 106 acting 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 be moved left and right along the preset spherical surface 107.

In an alternative embodiment, the lens module assembly 101 can also form a lever structure with the center of the preset sphere 107 as a fulcrum on a 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.

Specifically, referring to fig. 1, 5 and 6, the second driving mechanism 121 is disposed at the rear of the lens module assembly 101 and provides a second driving force in the left-right direction. The second driving mechanism 121 includes a second driving assembly, a driving groove 122, and a driving rod 123. The second driving assembly comprises a second driving device for outputting driving force, a bevel gear 124, an adjusting screw 125 and a locking buckle 126 for sequentially transmitting 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 mounted on the fixing frame 127, the fixing frame 127 is provided with a sliding rail, and the driving groove 122 is mounted in the sliding rail. The second driving device drives the bevel gear 124 to rotate, the adjusting screw 125 is rotated through gear engagement, and the rotation motion is converted into linear motion through the locking buckle 126 in threaded connection with the adjusting screw 125, so as to drive the driving groove 122 connected with the locking buckle 126 to move left and right.

The second driving component is connected to the driving slot 122 to drive the driving slot 122 to reciprocate in a second preset direction (the guiding direction of the sliding rail), where the second preset direction is located in the horizontal plane and perpendicular to the light emitting direction of the lens module assembly 101 (i.e. the left-right direction of the lens module assembly 101). One end of the driving rod 123 is connected with the tail end of the lens module assembly 101, the other end of the driving rod 123 is arranged in the driving groove 122, and the inner surface of the driving groove 122 is a cambered surface for driving the driving rod 123 to swing.

In this embodiment, when the driving groove 122 moves left and right, the inner surface of the driving groove 122 applies force to the end of the driving rod 123 to swing the outer lens 102 of the front end of the lens module assembly 101 left and right, and the swing direction of the outer lens 102 is opposite to the swing direction of the driving rod 123. The swing path of the driving rod 123 is an arc path, so that the inner surface of the driving groove 122 is set to be an arc surface so as to ensure that the driving groove 122 can be always contacted with the driving rod 123, and the depth of the driving rod 123 extending into the driving groove 122 can ensure that the driving rod 123 cannot be separated from the driving groove 122 in the swing process.

Alternatively, in the case of integrating the first driving mechanism 117 and the second driving mechanism 121, it is necessary to consider the connection relationship of the adjustment bracket and the lens module assembly 101, which are integrally connected, with the two driving mechanisms.

Referring to fig. 1 and 5, when the first driving mechanism 117 is operated, the adjusting bracket drives the lens module assembly 101 to swing up and down, and at this time, the position of the second driving mechanism 121 is unchanged, so the driving slot 122 is configured as an elongated slot structure having a moving path in the up-down direction, so that the driving rod 123 swinging up and down has a moving space, and two ends of the driving slot 122 in the up-down direction are also configured as arc surfaces to be matched with the moving path of the driving rod 123.

Referring to fig. 1 and 4, when the second driving mechanism 121 is operated, the lens module assembly 101 drives the adjusting bracket to swing left and right, and at this time, the position of the first driving mechanism 117 is unchanged, so that the guiding chute 120 is movably mounted on the adjusting mechanism 106. Specifically, the adjusting mechanism 106 is provided with a long strip hole 128 having a moving path in a left-right direction, and the guiding chute 120 is movably mounted in the long strip hole 128, so that the adjusting mechanism 106 can move left and right relative to the guiding chute 120, that is, a left-right adjusting function of the lens module assembly 101 is realized.
