Description

Technical Field

[0001] The utility model relates to the technical field of headlamp adjustment. Specifically, it relates to a light adjustment mechanism, and further relates to a headlamp. Background Art

[0002] With the development of the diversification of headlamp shapes, the demand for personalized customization has become higher and higher.

Specific implementation manners

[0031] The following will detail the specific implementation manners of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present utility model, and the protection scope of the present utility model is not limited to the following specific implementation manners.

[0032] Such as Figure 1 And Figure 2As shown in the figure, the first aspect of the present utility model provides a dimming mechanism, which is used in cooperation with a light-emitting mechanism. The dimming mechanism includes a main installation frame 1 and a fine-tuning frame 2. Among them, the main installation frame 1 includes at least one main installation position, at least one secondary installation position, a main frame connection seat 11, and at least one main frame adjustment seat 12. The light-emitting mechanism includes a first light unit fixedly installed at the main installation position and a second light unit adjustably installed at the secondary installation position. The second light unit is adjustably installed at the secondary installation position via the fine-tuning frame 2. It should be noted that the main installation frame 1 can be connected via the main frame connection seat 11 and the main frame connection structure, and is connected to the main frame adjustment structure via the main frame adjustment seat 12. Moreover, the main frame adjustment structure can drive the main installation frame 1 to rotate around at least one rotation direction on the main frame connection structure, so that the main frame adjustment structure can be used as the first-level adjustment structure, and the fine-tuning frame 2 adjustably installed at the secondary installation position can be used as the second-level adjustment structure.

[0033] Among them, the main frame connection structure can be a ball head rod, and the main frame adjustment structure can be a ball head screw. Correspondingly, both the main frame connection seat 11 and the main frame adjustment seat 12 can be ball head socket structures that can match the ball heads on the ball head rod or the ball head screw. Thus, by rotating and adjusting the ball head screw, the main installation frame 1 can be driven to rotate around at least one rotation direction on the ball head of the ball head rod, so as to realize the overall adjustment of the light-emitting directions of all the light units at the main installation position (especially the adjustment of the light-emitting direction of the light unit fixedly connected to the main installation position).

[0034] Based on the above technical solutions, the dimming mechanism of the present application can use each fine-tuning frame 2 as the second-level adjustment structure and the main installation frame 1 as the first-level adjustment structure, so as to realize the individual adjustment of the light-emitting directions of each light unit, and can reduce the usage amount of the most precise fine-tuning frame 2 and its supporting adjustment mechanism. Thus, the structure, manufacturing difficulty, and manufacturing cost of the dimming mechanism can be simplified. Moreover, during the dimming process, all the second light units at the secondary installation positions will be adjusted based on the light-emitting direction of the first light unit at the main installation position. After adjusting all the second light units, the overall light-emitting direction of the first light unit and the second light units is adjusted by adjusting the main installation frame 1. Therefore, the dimming process can be simplified and the dimming process can be made more hierarchical, and it is not easy to re-adjust the light-emitting directions of all the light units connected to the dimming mechanism due to the failure to adjust the light-emitting direction of one light unit in place.

[0035] The above-mentioned first light unit is the main low beam unit, and the second light unit includes at least one of a main high beam unit, an auxiliary low beam unit, and an auxiliary high beam unit. The main low beam unit and the auxiliary low beam unit form a low beam unit, and the main high beam unit and the auxiliary high beam unit form a high beam unit.

[0036] Specifically, asFigure 1 and Figure 2 As shown in Figure 2 , the main installation position can be used for fixedly connecting the main low beam unit, and two main frame adjusting seats 12 can be provided. Each main frame adjusting seat 12 is connected to the corresponding main frame adjusting structure, so as to drive the main installation frame 1 to rotate around two obliquely intersecting rotation directions on the main frame connection structure, for example, driving the main installation frame 1 to rotate around the horizontal direction and the vertical direction on the main frame connection structure, so as to be able to adjust the light output direction of the main low beam unit (and the overall light output direction of all the light units on the main installation frame 1).

[0037] As Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , the light adjusting mechanism of the present application further includes a linkage adjusting frame 3. When there are multiple auxiliary low beam units or auxiliary high beam units, the multiple auxiliary low beam units can be adjustably installed on a linkage adjusting frame 3 via the corresponding fine-tuning frames 2, and the multiple auxiliary high beam units can be adjustably installed on another linkage adjusting frame 3 via the corresponding fine-tuning frames 2, and can be adjustably installed on the auxiliary installation position via the corresponding linkage adjusting frame 3. Thus, when adjusting the light, the relative light output directions of the multiple auxiliary low beam units or multiple auxiliary high beam units on the same linkage adjusting frame 3 can be adjusted first, and then the linkage adjusting frame 3 is adjusted to adjust the relative light output directions between the multiple auxiliary low beam units or multiple auxiliary high beam units on the linkage adjusting frame 3 and other light units outside the linkage adjusting frame 3, so as to be able to simplify the light adjusting process and make the light adjusting process more hierarchical, and it is not easy to re-adjust the light output directions of all the light units connected to the light adjusting mechanism due to the light output direction of a light unit not being adjusted in place.

[0038] It should be noted that the linkage adjusting frame 3 needs to include a linkage frame connection seat 31 and at least one linkage frame adjusting seat 32. The main installation frame 1 is provided with a linkage frame connection structure connected to the linkage frame connection seat 31 and a linkage frame adjusting structure connected to the linkage frame adjusting seat 32, and the linkage frame adjusting structure can drive the linkage adjusting frame 3 to rotate around at least one rotation direction on the linkage frame connection structure; the fine-tuning frame 2 includes a fine-tuning frame connection seat 21 and at least one fine-tuning frame adjusting seat 22. The linkage adjusting frame 3 is provided with a fine-tuning frame connection structure connected to the fine-tuning frame connection seat 21 and a fine-tuning frame adjusting structure connected to the fine-tuning frame adjusting seat 22, and the fine-tuning frame adjusting structure can drive the fine-tuning frame 2 to rotate around at least one rotation direction on the fine-tuning frame connection structure.

[0039] Among them, the linkage frame connection structure can be a ball head rod, and the linkage frame adjustment structure can be a ball head screw. Correspondingly, both the linkage frame connection seat 31 and the linkage frame adjustment seat 32 can be ball and socket structures that can match the ball heads on the ball head rod or the ball head screw. Thus, by rotating and adjusting the ball head screw, the linkage mounting frame can be driven to rotate around the ball head of the ball head rod in at least one rotation direction, so as to realize the overall adjustment of the light output directions of all the light units on the linkage adjustment frame 3. And the linkage frame adjustment seat 32 can be set to two, and each linkage frame adjustment seat 32 is connected to the corresponding linkage frame adjustment structure, so as to drive the linkage adjustment frame 3 to rotate around two obliquely intersecting rotation directions on the linkage frame connection structure. For example, driving the linkage adjustment frame 3 to rotate around the horizontal direction and the vertical direction on the linkage frame connection structure, so as to realize the adjustment of the overall light output direction of all the light units on the linkage adjustment frame 3.

[0040] Similarly, the fine adjustment frame connection structure can be a ball head rod, and the fine adjustment frame adjustment structure can be a ball head screw. Correspondingly, both the fine adjustment frame connection seat 21 and the fine adjustment frame adjustment seat 22 can be ball and socket structures that can match the ball heads on the ball head rod or the ball head screw. Thus, by rotating and adjusting the ball head screw, the fine adjustment frame 2 can be driven to rotate around the ball head of the ball head rod in at least one rotation direction, so as to realize the overall adjustment of the light output direction of the light unit on the fine adjustment frame 2. And the fine adjustment frame adjustment seat 22 can be set to two, and each fine adjustment frame adjustment seat 22 is connected to the corresponding fine adjustment frame adjustment structure, so as to drive the fine adjustment frame 2 to rotate around two obliquely intersecting rotation directions on the fine adjustment frame connection structure. For example, driving the fine adjustment frame 2 to rotate around the horizontal direction and the vertical direction on the fine adjustment frame connection structure, so as to realize the adjustment of the light output direction of the light unit on the fine adjustment frame 2.

[0041] The layout forms of the low beam unit and the high beam unit can be specifically adjusted according to the styling requirements of the vehicle lamp.

[0042] Taking the common non-narrow vehicle lamp as an example, as Figure 3 shown, the main low beam unit and the auxiliary low beam unit can be arranged along the horizontal direction, the main high beam unit and the auxiliary high beam unit are also arranged along the horizontal direction, and the low beam unit is arranged above the high beam unit; or, the main low beam unit and the auxiliary low beam unit can be arranged along the vertical direction, the main high beam unit and the auxiliary high beam unit are also arranged along the vertical direction, and the low beam unit is arranged on one side of the high beam unit close to or far from the central axis in the vehicle length direction.

[0043] If the vehicle lamp is a narrow vehicle lamp extending along the horizontal direction, then as Figure 4As shown, the main low beam unit and the auxiliary low beam unit can be arranged horizontally, the main high beam unit and the auxiliary high beam unit can also be arranged horizontally, and the low beam unit and the high beam unit are at the same height.

[0044] If the vehicle lamp is a narrow-shaped lamp extending in the vertical direction, then as Figure 5 shown, the main low beam unit and the auxiliary low beam unit can be arranged vertically, the main high beam unit and the auxiliary high beam unit can also be arranged vertically, and the low beam unit is arranged above the high beam unit.

[0045] Compared with the prior art, in which a set of dimming mechanisms is provided for all low beam modules, a set of dimming mechanisms is provided for all high beams, and a joint adjustment structure is used between the low beam modules and the high beam modules, in this application, multiple sets of dimming mechanisms are combined into one set of dimming mechanisms, which greatly reduces the cost and saves space.

[0046] Based on the implementation of the dimming mechanism in the above technical solution, the dimming method includes the following steps:

[0047] In response to one main low beam unit, one main high beam unit, one auxiliary low beam unit, and one auxiliary high beam unit being provided respectively, first adjust the fine-tuning frame 2 corresponding to the main high beam unit to adjust the light-emitting direction of the main high beam unit relative to the main low beam unit, then adjust the fine-tuning frame 2 corresponding to the auxiliary high beam unit to adjust the light-emitting direction of the auxiliary high beam unit relative to the main high beam unit, then adjust the main mounting frame 1 to adjust the light-emitting direction of the main low beam unit, and finally adjust the fine-tuning frame 2 corresponding to the auxiliary low beam unit to adjust the light-emitting direction of the auxiliary low beam unit relative to the main low beam unit;

[0048] In response to one main low beam unit and one main high beam unit being provided respectively, and multiple auxiliary low beam units and multiple auxiliary high beam units being provided, first adjust the fine-tuning frame 2 corresponding to the main high beam unit to adjust the light-emitting direction of the main high beam unit relative to the main low beam unit, then adjust each fine-tuning frame 2 corresponding to the auxiliary high beam units to adjust the light-emitting directions between the auxiliary high beam units. It should be noted that the auxiliary high beam units can be adjusted in the order from near to far from the main high beam unit. Then adjust the linkage adjustment frame 3 to adjust the light-emitting directions of the auxiliary high beam units relative to the main high beam unit, then adjust the main mounting frame 1 to adjust the light-emitting direction of the main low beam unit, then adjust each fine-tuning frame 2 corresponding to the auxiliary low beam units to adjust the light-emitting directions between the auxiliary low beam units. It should be noted that the auxiliary low beam units can be adjusted in the order from near to far from the main low beam unit, and finally adjust the linkage adjustment frame 3 to adjust the light-emitting directions of the auxiliary low beam units relative to the main low beam unit.

[0049] After the relative light-emitting directions of the light units on the same linkage adjustment frame 3 are adjusted, the linkage adjustment frame 3 can be adjusted to adjust the relative light-emitting direction between the whole of the light units on the linkage adjustment frame 3 and other light units outside the linkage adjustment frame 3, so that the dimming process can be simplified and the dimming process can be made more hierarchical, and it is not easy to re-adjust the light-emitting directions of all the light units connected to the dimming mechanism due to the failure to adjust the light-emitting direction of a single light unit properly.

[0050] The second aspect of the present invention provides a vehicle headlamp, which has the dimming mechanism in the above technical solution, and thus also has all the technical effects of the above dimming mechanism.

[0051] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0052] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0053] In addition, any combination can be made between different embodiments of the present invention as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
