[0033] The utility model discloses a connecting rod of a vehicle lamp adjustment mechanism, which is adapted to different installation requirements, reduces the use of extension rods, and reduces costs. In addition, the utility model also discloses a vehicle lamp and a vehicle having the connecting rod of the vehicle lamp adjustment mechanism.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0036] The headlights of vehicles all need an adjustment mechanism to adjust the irradiation position of the headlights. Currently, the headlight adjustment mechanisms are generally divided into manual adjustment mechanisms and electric adjustment mechanisms.

[0037] Due to space constraints on the headlights, the adjustment points for headlight adjustment are usually arranged on the ground side of the headlights, and manual adjustment cannot be performed directly. The usual practice is to add an adjustment extension rod. The use of the extension rod requires a large amount of space outside the headlight. When one extension rod cannot meet the manual adjustment requirements, it needs to be extended a second time, making adjustment difficult, and the adjustment is prone to jamming after multiple conversions. Additional parts are required to fix the extension rod to the lamp housing, resulting in increased costs.

[0038] Based on the above problems, the present application discloses a connecting rod of a headlight adjustment mechanism. The connecting rod is a flexible structure and can be bent to adapt to different installation space requirements, thereby eliminating the need for additional extension rods. This is beneficial for reducing the number of rods, improving assembly efficiency, and reducing costs. The reduction in the number of rods can reduce the difficulty of adjustment and alleviate the problem of sticking.

[0039] Specifically, Figures 1 to 9 The connecting rod of the vehicle light adjustment mechanism shown comprises an inner flexible rod 200 and an outer flexible protective cover 100 .

[0040] Among them, the internal flexible rod 200 is a flexible structure that can be bent, and the first end of the internal flexible rod 200 has a gear 201 for engaging and transmitting with the adjustment point on the lamp housing of the vehicle lamp, and the second end of the internal flexible rod 200 is used to adapt to the adjustment tool; the external flexible protective cover 100 is a flexible structure that can be bent, and the external flexible protective cover 100 is connected to the internal flexible rod 200, and the external flexible protective cover 100 is used to be detachably connected to the lamp housing.

[0041] The second end of the internal flexible rod 200 in the present application is used to adapt to the adjustment tool to facilitate the operator to adjust. The first end of the internal flexible rod 200 has a gear 201, which is meshed with the adjustment point on the lamp housing to transmit the torsional force applied by the operator to the lamp housing through the gear meshing to adjust the irradiation position of the vehicle lamp. The external flexible protective cover 100 is detachably connected to the lamp housing to achieve installation of the connecting rod.

[0042] The connecting rod of the headlight adjustment mechanism in the present application is a flexible structure that can be bent and adapt to different installation spaces. No additional extension rod is required, which is beneficial to reducing the number of rods, improving assembly efficiency, and reducing costs. The reduction in the number of rods can reduce the difficulty of adjustment and alleviate the problem of sticking.

[0043] Combination Figure 3 and Figure 4 As shown, the second end of the internal flexible rod 200 in the present application has a hollow truncated cone 202 for inserting an adjustment tool (e.g., a screwdriver). The depth of the truncated cone 202 can be set according to different needs. In an optional embodiment, the bottom of the truncated cone 202 has a cross pattern that can be adapted to the adjustment tool, or the cross-section of the inner wall of the truncated cone 202 is a hexagon.

[0044] The shape and size of the interior of the table 202 can be set according to the shape and size of the adjustment tool. In the present application, the adjustment tool is exemplified as a screwdriver, and the cross-section of the inner wall of the table 202 is set to a hexagon. The screwdriver can be fitted with the inner wall of the table 202 to facilitate the operator to drive the connecting rod to rotate; when the screwdriver is a cross-pattern screwdriver, the screwdriver can be pressed against the cross pattern on the inner bottom of the table 202 to rotate the connecting rod.

[0045] Those skilled in the art will appreciate that the manner in which the table 202 cooperates with the adjustment tool includes but is not limited to the manner disclosed in the above embodiments, and any manner that allows the operator to easily rotate the connecting rod by cooperating with the table 202 is within the protection scope.

[0046] Figure 3 As shown, the gear 201 of the internal flexible rod 200 in the present application is a bevel gear, and the diameter of the bevel gear gradually increases from the first end of the internal flexible rod 200 to the second end of the internal flexible rod 200. The gear 201 in the present application is a bevel gear to change the transmission direction, and the type of the gear 201 can be set according to the transmission needs, and other types of gears 201 are also within the protection scope.

[0047] The internal flexible rod 200 and the external flexible protective cover 100 in the present application are connected in a limited position along the axial direction of the internal flexible rod 200, and are connected in a rotational manner along the circumferential direction of the internal flexible rod 200. The internal flexible rod 200 and the external flexible protective cover 100 in the present application can rotate relative to each other, so that after the external flexible protective cover 100 is connected to the lamp housing, the internal flexible rod 200 can rotate alone without the need for the external flexible protective cover 100 to rotate together, thereby reducing the force required by the operator during the rotation process, thereby reducing the difficulty of operation, and also ensuring the stability of the connection of the external flexible protective cover 100, thereby preventing the external flexible protective cover 100 from being separated from the lamp housing.

[0048] Combination Figures 6 to 9 The illustrated embodiment discloses a connection method between the internal flexible rod 200 and the external flexible protective cover 100. Specifically, a first boss 203 is provided at the first end of the internal flexible rod 200, a first engaging groove (not shown in the figure) is formed between the first boss 203 and the gear 201, and one end of the external flexible protective cover 100 is engaged with the first boss 203 and the first engaging groove. In some embodiments, a second boss 204 is provided at the second end of the internal flexible rod 200, a second engaging groove (not shown in the figure) is formed between the second boss 204 and the round table 202, and the other end of the external flexible protective cover 100 is engaged with the second boss 204 and the second engaging groove.

[0049] In the present application, the internal flexible rod 200 and the external flexible protective sleeve 100 are limited in the axial direction and their relative rotation is achieved by using the matching mode of the clamping groove and the boss. It can be understood by those skilled in the art that the internal flexible rod 200 and the external flexible protective sleeve 100 can achieve axial limitation and circumferential rotation through the boss and the clamping groove at one end, or can achieve axial limitation and circumferential rotation through the boss and the clamping groove at both ends to improve the stability of the connection between the internal flexible rod 200 and the external flexible protective sleeve 100. Of course, in other embodiments, the internal flexible rod 200 and the external flexible protective sleeve 100 can also be connected in rotation through a bearing.

[0050] See also Figures 5 to 7 As shown, the first end and the second end of the outer flexible protective cover 100 are both provided with connecting ears for connecting with the lamp housing, and the connecting ears are threadedly connected with the lamp housing through a screw member. Specifically, the first end of the outer flexible protective cover 100 has a first connecting ear 101, and the second end has a second connecting ear 102.

[0051] After the outer flexible protective cover 100 and the inner flexible rod 200 are connected, the first connecting ear 101 is located on one side of the gear 201, and the gear 201 extends out of the outer flexible protective cover 100. The second connecting ear 102 is located on one side of the truncated cone 202, and the truncated cone 202 extends out of the outer flexible protective cover 100.

[0052] In some embodiments, the connecting ear is integrally formed with the external flexible protective cover 100, so that the external flexible protective cover 100 has a connection structure for connecting with the lamp housing, and no additional fixing bracket is required, which saves costs. The connecting ear can fit and position with the lamp housing, and a positioning hole and a threaded hole are provided on the connecting ear to facilitate the connection between the connecting ear and the lamp housing.

[0053] In addition, the present application also discloses a vehicle lamp, including the vehicle lamp adjustment mechanism disclosed in the above embodiments. Therefore, the vehicle lamp having the vehicle lamp adjustment mechanism also has all the above technical effects, which will not be described one by one here.

[0054] In addition, the present application also discloses a vehicle, including the headlight disclosed in the above embodiment. Therefore, the vehicle with the headlight also has all the above technical effects, which will not be described one by one here.

[0055] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0056] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
