DETAILED DESCRIPTION
[0020] The following is further described in detail through specific implementation methods: Example
[0021] Basically as attached Figure 1-5 As shown, a vehicle headlamp adjustment structure comprises an adjustment rod 1, a first guide rod 2, a second guide rod 3 and a universal joint seat 4. The universal joint seat 4 is provided with an adjustment threaded hole 401, a first guide hole 402, a second guide hole 403 and a ball head 404. The adjustment threaded hole 401, the first guide hole 402 and the second guide hole 403 are respectively used to install the adjustment rod 1, the first guide rod 2 and the second guide rod 3. A ball head seat 5 is installed on the ball head 404, and the ball head seat 5 is used to install the headlamp bracket 10.
[0022] The adjusting rod 1 is provided with a threaded section 101, a sealing ring groove 102 and a supporting round seat 103 in sequence. The threaded section 101 is provided with a thread matching the adjusting threaded hole 401 and passes through the adjusting threaded hole 401 toward the headlamp bracket 10. The sealing ring groove 102 and the supporting round seat 103 are respectively connected to the two sides of the headlamp shade 9. A sealing assembly is provided at the connection between the sealing ring groove 102 and the headlamp shade 9. The sealing assembly includes a plum blossom washer, a spring washer and a sealing ring (not shown in the drawings) installed in sequence. The sealing assembly can ensure that the adjusting rod 1 is tightly connected to the headlamp shade 9 and will not damage the headlamp shade 9 during adjustment.
[0023] One end of the first guide rod 2 and the second guide rod 3 is provided with a limiting ring groove 201, and the other end is provided with a mounting seat 202, and the mounting seat 202 is provided with a fixing screw hole 203. The ends of the first guide rod 2 and the second guide rod 3 provided with the limiting ring groove 201 pass through the first guide hole 402 and the second guide hole 403 respectively. The mounting seat 202 and the fixing screw hole 203 are used to fix the first guide rod 2 and the second guide rod 3 on the headlight cover 9. In this way, the universal joint seat 4 is assembled on the first guide rod 2, the second guide rod 3 and the adjustment rod 1, which can avoid the structural instability caused by using only the adjustment rod 1, improve the overall strength of the adjustment structure, and prevent the adjustment structure from falling off.
[0024] The adjusting threaded hole 401, the first guide hole 402 and the second guide hole 403 in the universal joint seat 4 vertically penetrate the universal joint seat 4 and are parallel to each other, and the hole center connection line of the adjusting threaded hole 401, the first guide hole 402 and the second guide hole 403 is a triangle. In this way, it can be ensured that the first guide rod 2, the second guide rod 3 and the adjusting rod 1 are parallel to each other after assembly and form a triangular stable structure, thereby increasing the matching strength of the adjusting structure.
[0025] The utility model includes a limit insert 6, and the two ends of the limit insert 6 are respectively provided with a mounting groove 601, and a limit hole 602 matching the limit ring groove 201 is provided at the center of the mounting groove 601. The limit holes 602 at the two ends of the limit insert 6 are respectively installed in the limit ring groove 201 of the first guide rod 2 and the second guide rod 3. The limit insert 6 plays a role of limiting and adjusting the universal joint seat 4, so that it can move on a predetermined track, and prevent the adjustment structure from failing and causing losses.
[0026] To summarize, in order to avoid the problem of insufficient adjustment strength of the adjustment rod 1, the first guide rod 2, the second guide rod 3 and the universal joint seat 4 are introduced, the first guide rod 2 and the second guide rod 3 are screwed to the headlamp housing 9, and the universal joint seat 4 is assembled on the adjustment rod 1 and the first guide rod 2, the second guide rod 3. Through the mutual cooperation and connection between the first guide rod 2, the second guide rod 3, the universal joint seat 4 and the adjustment rod 1, a triangular stable structure is formed, the cooperation strength of the adjustment structure is increased, and the adjustment mechanism is prevented from falling off.
[0027] At the same time, the adjustment structure enables the universal joint seat 4 to flexibly move up and down on the adjustment rod 1 through the guiding effect of the first guide rod 2 and the second guide rod 3, avoiding the blind angle of adjustment and keeping its movement more stable. In order to avoid excessive adjustment movement of the adjustment mechanism, causing part of the structure to deviate from the established movement trajectory and cause the separation phenomenon, the limit insert 6 is introduced. The limit insert 6 is fixed on the guide rod and plays a role of limiting the universal joint seat 4 so that it can move on the established trajectory, preventing the adjustment structure from failing and causing losses.
[0028] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here.
