[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0025] Please refer to Figures 1 to 5 : a light angle adjusting device of an LED vehicle lamp, comprising: a lamp body 100 and a hemispherical shell 200, the hemispherical shell 200 is installed on the rear side of the lamp body 100 for supporting the lamp body 100, and a rolling groove 102 for installing a rolling ball 120 is formed on the top and bottom of the lamp body 100.
[0026] The rear side of the lamp body 100 is provided with a rack 110 for engaging with the driving gear 400. The rack 110 is arc-shaped structure. The inner side of the hemispherical shell 200 is provided with a group of sliding grooves 202 above and below for sliding of the ball 120. The rear side of the hemispherical shell 200 is provided with an outlet 203 for extending the rack 110.
[0027] The radius length of the rear side of the lamp body 100 matches the radius length of the inner side of the hemispherical shell 200. The left and right sides of the lamp body 100 are each provided with a group of rotating grooves 101 for abutting with the support plate 300.
[0028] The rear side of the support plate 300 is connected and fixed with the rear side of the lamp shell. The front inner side of the support plate 300 is movably connected with the two groups of rotating grooves 101 on the left and right sides of the lamp body 100 through two groups of rotating shafts.
[0029] The left and right sides of the hemispherical shell 200 are each provided with a group of fixed grooves 201 for fixed connection with the support plate 300. The two groups of fixed grooves 201 are fixed with the two groups of fixed shafts installed on the front inner side of the support plate 300. The hemispherical shell 200 is fixed between the two groups of support plates 300 and remains stationary. The rear side of the lamp body 100 rotates inside the hemispherical shell 200, so the rotating shaft rotates inside the rotating groove 101, ensuring that the lamp body 100 can freely rotate between the two groups of support plates 300.
[0030] The inner arc surface of the rack 110 is glued with the rear side of the lamp body 100. The length of the rack 110 is equal to half the length of the outlet 203. The width and thickness of the rack 110 match the width and depth of the outlet 203.
[0031] The outer arc surface of the rack 110 engages with the front side of the driving gear 400. The driving gear 400 is embeddedly installed on the rear side of the lamp shell. The driving gear 400 is connected with the output end of the motor embeddedly installed on the rear side of the lamp shell through a shaft coupling. The motor is a servo motor. The motor is connected with a servo system, which can control the rotation direction and rotation angle of the motor. The motor drives the driving gear 400 to rotate, thereby driving the rack 110 to move, and then driving the lamp body 100 to adjust the angle up and down.
[0032] The ball 120 is embeddedly installed inside the rolling groove 102. The side of the rolling groove 102 away from the center of the lamp body 100 is an open structure. The side of the ball 120 away from the center of the lamp body 100 extends outside the rolling groove 102.
[0033] The radius length of the ball 120 matches the radius length of the rolling groove 102, and the radius length of the ball 120 matches the width and depth of the sliding groove 202. By rotating the ball 120 inside the rolling groove 102, the sliding friction between the rear side of the lamp body 100 and the inner side of the hemispherical shell 200 can be converted into the rolling friction of the ball 120 inside the rolling groove 102, thereby significantly reducing the friction received by the lamp body 100 when rotating, making the up and down adjustment of the lamp body 100 more sensitive.
[0034] Embodiment 1: Please refer to Figures 1 to 5 In actual use, the lamp body 100 is installed inside the lamp shell, and the rotating grooves 101 on the left and right sides of the lamp body 100 are respectively connected to the two groups of rotating shafts on the front inner sides of the two groups of support plates 300 on the left and right sides of the lamp body 100, so that the lamp body 100 can be conveniently rotated. The rear side of the lamp body 100 is placed inside the hemispherical shell 200, and the two groups of fixed grooves 201 opened on the left and right sides of the hemispherical shell 200 are respectively connected to the two groups of fixed shafts on the rear side of the two groups of rotating shafts, so that the position of the hemispherical shell 200 is fixed between the two groups of support plates 300, thereby facilitating the rotation of the rear side of the lamp body 100 inside the hemispherical shell 200. The rear side of the rack 110 glued to the rear side of the lamp body 100 passes through the outlet 203 opened through the rear side of the hemispherical shell 200, and the rear side of the rack 110 is engaged with the front side of the drive gear 400 embedded and installed on the rear side of the lamp shell.
[0035] The drive gear 400 rotates counterclockwise under the drive of the motor, and the motor is a servo motor connected with a servo system, which can control the rotation direction and rotation angle of the motor (the motor is a prior art, and its internal structure and working principle will not be described here). The motor rotates counterclockwise, driving the drive gear 400 to rotate counterclockwise, thereby driving the rack 110 to move upward inside the outlet 203. Since the rack 110 is glued to the rear side of the lamp body 100, the lamp body 100 moves downward when the rack 110 moves upward, thereby adjusting the illumination angle of the lamp body 100 downward. Similarly, the motor can be rotated clockwise to control the drive gear 400 to rotate clockwise, thereby driving the rack 110 to move downward, and then driving the lamp body 100 to adjust the illumination angle upward. Therefore, the final effect is that the engagement between the drive gear 400 and the rack 110 can control the up and down adjustment of the angle of the lamp body 100 inside the lamp shell, thereby adapting to the demand of the running light of different road sections.
[0036] Embodiment 2: Please refer to Figure 4 and Figure 5When the rear side of the lamp body 100 rotates inside the hemispherical shell 200, the top of the rolling ball 120 embedded in the rolling groove 102 at the top of the lamp body 100 contacts the inner side of the sliding groove 202 at the top of the inner side of the hemispherical shell 200, and the bottom rolling ball 120 of the lamp body 100 contacts the inner side of the sliding groove 202 at the bottom of the inner side of the hemispherical shell 200. When the lamp body 100 rotates downward, the upper rolling ball 120 slides from the right side of the upper sliding groove 202 to the left side of the upper sliding groove 202, so that the upper rolling ball 120 rotates inside the upper rolling groove 102, and the lower rolling ball 120 slides from the left side of the lower sliding groove 202 to the right side of the lower sliding groove 202, and the lower rolling ball 120 rotates inside the lower rolling groove 102. Then, through the arrangement of the two groups of rolling balls 120, the direct contact between the outer side of the lamp body 100 and the inner side of the hemispherical shell 200 is avoided, so that the sliding friction between the outer side of the lamp body 100 and the inner side of the hemispherical shell 200 is converted into the rolling friction of the rolling ball 120 inside the rolling groove 102, thereby greatly reducing the friction when the lamp body 100 rotates, and making the lamp body 100 more sensitive when adjusting up and down.
[0037] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
