Fig. 5 illustrates a right side view of a license plate lighting device test system according to one embodiment of the invention. Fig. 6 is a schematic view of the C-C direction of fig. 3. As shown, a license plate lighting device testing system 100 includes a base 101, a column 102, an up-down moving plate 103, a back-and-forth moving plate 104, a license plate lamp control plate 105, a license plate fixing plate 106, and a driving mechanism 107.
Wherein, the columns 102 can be arranged in two, and are vertically arranged on the base 101 at intervals.
The up-and-down moving plate 103 is parallel to the longitudinal direction of the column 102 and is spaced apart from the column 102 by a set distance. The up-and-down moving plate 103 can move up and down with respect to the column 102, and the up-and-down moving plate 103 can be fixed after moving to a proper position.
The back and forth moving plate 104 is provided above the up and down moving plate 103. The front-rear moving plate 104 can be moved forward and backward in the horizontal direction with respect to the up-down moving plate 103, and the front-rear moving plate 104 can be fixed after the front-rear moving plate 104 is moved to a proper position.
The license plate lamp control board 105 is used for assembling license lamps. The license lamp control board 105 is disposed at the rear side of the front and rear moving board 104, and the license lamp control board 105 can be turned over a set angle with respect to the front and rear moving board 104 and fixed. The turning axis of the license lamp control plate 105 is perpendicular to the up-down movement direction of the up-down movement plate 103 and the forward-backward movement direction of the forward-backward movement plate 104.
The license plate fixing plate 106 is used for assembling license plates, and the license plate fixing plate 106 is disposed below the license lamp control board 105. The license plate fixing plate 106 can be turned over a set angle with respect to the front-rear moving plate 104 and fixed, and the turning axis of the license plate fixing plate 106 is parallel to the turning axis of the license lamp control plate 105. As shown in fig. 2 and 5, the license plate fixing plate 106 is fixed to a C-shaped fixing column 108, and the C-shaped fixing column 108 is fixed to the top of the base 101. By way of example and not limitation, license plate anchor plate 106 may also be secured directly to post 102.
The driving mechanism 107 is mainly used for driving the up-and-down moving plate 103 to move up and down, the front-and-back moving plate 104 to move back and forth, and the license plate lamp control plate 105 and the license plate fixing plate 106 to turn over. Wherein, in the up-and-down movement process of the up-and-down movement plate 103, the up-and-down movement plate 104 moves along with the up-and-down movement plate 103, and in the up-and-down movement process of the up-and-down movement plate 104, the license lamp control plate 105 moves along with the up-and-down movement plate 104.
During the testing of the lighting device testing system 100, the license plate lamp affixed to the license plate lamp control board 105 needs to be irradiated to the license plate affixed to the license plate fixing board 106 at a proper angle and distance to detect the light-emitting brightness on the license plate. Therefore, the main function of the lighting device testing system 100 is to adjust the height and the front and rear positions of license plate lamps relative to the license plate by the movement of the up-down moving plate 103 and the front-rear moving plate 104, and adjust the incident angle of the license plate lamps reaching the license plate by the turning of the license plate lamp control plate 105 and the license plate fixing plate 106.
Preferably, license plate lighting device test system 100 further includes a first rotating assembly 109. Referring to fig. 1, the first rotation assembly 109 includes a first gear shaft 110 and a first rack 111. Wherein, the first gear shaft 110 is horizontally disposed on the upright post 102, the first gear 112 is disposed on the first gear shaft 110, and the first rack 111 is vertically disposed on the up-down moving plate 103. The first gear 112 is meshed with the first rack 111, and the driving mechanism 107 can drive the first gear shaft 110 to rotate, so that the up-down moving plate 103 is driven to move up and down through the cooperation of the first gear 112 and the first rack 111, and then the high-low position of the license lamp control plate 105 on the front-back moving plate 104 is driven.
Preferably, license plate lighting device test system 100 further includes a second rotating assembly 113. The second rotating assembly 113 is identical in structure to the first rotating assembly 109. The second rotating assembly 113 includes a second gear shaft 114 and a second rack 115, the second gear shaft 114 is horizontally disposed at the top of the up-down moving plate 103, a second gear 116 is disposed on the second gear shaft 114, the second rack 115 is horizontally disposed at the bottom of the front-rear moving plate 104, and the second gear 116 is engaged with the second rack 115. Since the moving directions of the up-down moving plate 103 and the forward-backward moving plate 104 are different, the first rack 111 and the second rack 115 are perpendicular to each other. The driving mechanism 107 can drive the second gear shaft 114 to rotate, so as to drive the front-back moving plate 104 to move back and forth through the cooperation of the second gear 116 and the second rack 115, and further drive the front-back position of the license lamp control plate 105.
Preferably, the license lamp control board 105 is provided with a first spindle 117. Rotation of the first shaft 117 causes the license lamp control plate 105 to turn over a set angle with respect to the back and forth movement plate 104. The license plate 106 is provided with a second rotating shaft 118, and the rotation of the second rotating shaft 118 can drive the license plate 106 to turn over a set angle relative to the back and forth moving plate 104. The angles of the first rotation shaft 117 and the second rotation shaft 118 are adjusted to adjust the incident angle of the license plate illuminated on the license plate fixing plate 106 by the lamp light of the license plate lamp provided on the license plate lamp control board 105.
Preferably, the driving mechanism 107 is capable of driving the first gear shaft 110, the second gear shaft 114, the first rotation shaft 117, and the second rotation shaft 118 to rotate, respectively. Specifically, the driving mechanism 107 may alternatively drive any one of the first gear shaft 110, the second gear shaft 114, the first rotation shaft 117, and the second rotation shaft 118. The driving mechanism 107 drives the first gear shaft 110 and the second gear shaft 114 to adjust the height and the front-rear position of the license lamp relative to the license plate. The driving mechanism 107 drives the first rotation shaft 117 and the second rotation shaft 118 to adjust the incidence angle of the license lamp light reaching the license plate. Further, referring to fig. 2, the driving mechanism 107 includes a servo motor 119, a servo motor speed reducer 120, a driving gear 121, a transition gear 122, and a driven gear 123. The servo motor 119 drives the driving gear 121 to rotate through the servo motor speed reducer 120, the driving gear 121 is engaged with the transition gear 122, and the transition gear 122 is engaged with the driven gear 123. Therefore, the servo motor 119 can drive the driving gear 121 to rotate, and drive the driven gear 123 to synchronously rotate through the transition gear 122. As shown in fig. 4, the driven gear 123 can be moved a set distance along the axial direction thereof, i.e., the driven gear 123 can be moved in the horizontal direction. Without separating from the transition gear 122, the driven gear 123 moves horizontally, so that the driven gear 123 can be respectively matched and fixed with the end of any one of the first gear shaft 110, the second gear shaft 114, the first rotating shaft 117 and the second rotating shaft 118, and the servo motor 119 drives the driving gear 121, the transition gear 122 and the driven gear 123 to act sequentially. The first gear shaft 110, the second gear shaft 114, the first rotation shaft 117 and the second rotation shaft 118 connected thereto are driven by the driven gear 123 to complete the up-down movement of the up-down moving plate 103, the forward-backward movement of the forward-backward moving plate 104, and the turning action of the first rotation shaft 117 and the second rotation shaft 118. Conventionally, the driven gear 123 has a length along its axis that is greater than the corresponding length of the transition gear 122, and is designed such that the driven gear 123 remains engaged with the transition gear 122 during lateral movement.
Preferably, the drive mechanism 107 further comprises a first swing arm 124 and a second swing arm 125. Referring to fig. 2, one end of the first swing arm 124 is rotatably coupled to an output shaft of the servo motor reducer 120, and the other end is rotatably coupled to a rotation shaft of the transition gear 122. Specifically, one end of the first swing arm 124 is sleeved on the output shaft of the servo motor reducer 120, and can rotate relatively around the output shaft of the servo motor reducer 120, but does not rotate along with the output shaft. One end of the second swing arm 125 is in running fit with the rotation shaft of the transition gear 122, and the other end is in running fit with the rotation shaft of the driven gear 123. In this structure, as shown in conjunction with fig. 6, the angle between the first swing arm 124 and the second swing arm 125 is kept unchanged, and the first swing arm 124 and the second swing arm 125 are rotated at the same time, so that the second swing arm 125 can rotate around the output shaft of the servo motor reducer 120 with the first swing arm 124. It is apparent that the first swing arm 124 is kept stationary and the second swing arm 125 can also rotate around the axis of rotation of the transition gear 122. Thus, the driven gear 123 which is in rotation fit with the other end of the second swing arm 125 can be in fit connection with the end of other parts/rotating shafts within the area range that the sum of the lengths of the first swing arm 124 and the second swing arm 125 is the radius. In this way, the driven gear 123 can selectively drive the first gear shaft 110, the second gear shaft 114, the first rotation shaft 117, and the second rotation shaft 118 to complete the up-down movement of the up-down moving plate 103, the forward-backward movement of the forward-backward moving plate 104, and the turning action of the first rotation shaft 117 and the second rotation shaft 118. Accordingly, the first gear shaft 110, the second gear shaft 114, the first rotation shaft 117, and the second rotation shaft 118 are maintained in substantially the same vertical plane at the end portion near the driving mechanism 107, and the end portions are substantially the same size, so that they are easy to be driven in cooperation with the driven gear 123. In addition, if the rotation coverage areas of the first swing arm 124 and the second swing arm 125 are to be enlarged, the lengths of the first swing arm 124 and the second swing arm 125 need only be lengthened.

The touch screen 134 is controlled to input a required rotation angle, the driven gear 123 drives the first rotation shaft 117 to rotate through the controller and is executed by the driving motor, and after the set rotation angle is reached, the hoop 135 of the first rotation shaft 117 is locked to fix the first rotation shaft, so that the required turnover angle of the license plate lamp fixing plate 126 is completed. The anchor 135 that releases the driven gear 123 pushes the driven gear 123 to the left to disengage the first shaft 117.
Step three: the first swing arm 124 and the second swing arm 125 are rotated to align the driven gear 123 with the end of the second gear shaft 114, then the driven gear 123 is pushed to move right to be matched with the end of the second gear shaft 114, and the anchor ear 135 of the driven gear 123 is locked to be matched and fixed with the front and back moving gear shaft into a whole. The driven gear 123 is kept in mesh with the transition gear 122.

The anchor 135 of the driven gear 123 is released and pushed to the left until the driven gear 123 is disengaged from the second gear shaft 114.
Step four: the first swing arm 124 and the second swing arm 125 are rotated to align the driven gear 123 with the first gear shaft 110, then the driven gear 123 is pushed to move right to be matched with the first gear shaft 110, the anchor ear 135 of the driven gear 123 is locked to be connected with the up-and-down moving gear shaft into a whole, and the driven gear 123 still keeps meshed with the transition gear 122. The required rotation angle is input on the touch screen 134, and is transmitted to the first gear 112 on the first gear shaft 110 through the controller and the driving mechanism 107, so that the first rack 111, the up-and-down moving plate 103, all parts mounted on the first rack and the license lamp fixing plate 126 and the like are driven to move up and down together, so that the license lamp is fixed by locking the anchor ear 135 of the first gear shaft 110 after moving up and down to the required height, and the mounting of the up-and-down position of the license lamp is completed. At this time, the anchor ear 135 of the driven gear 123 is not loosened, and the weight of the up-and-down moving plate 103 and all parts mounted thereon is borne together by the torsion of the servo motor 119, so that a subsequent test state is entered.
