Utility Model Content

[0006] To address the aforementioned issues, this invention provides a small-sized lens module with an adjustable angle. This product has a compact structure, is easy to install and debug, and can effectively improve the working performance of the lens module.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figure 1As shown, this embodiment of the utility model provides a small-sized lens module with adjustable angle, including a dimming bracket assembly 1 for mounting and fixing a low beam module assembly. The dimming bracket assembly 1 has two mounting cavities, in which a main low beam module assembly 2 and an auxiliary low beam module 3 are respectively mounted. The main low beam module assembly 2 and the auxiliary low beam module 3 have the same or similar structures. The main low beam module assembly 2 and the auxiliary low beam module 3 cooperate with the vehicle's overall headlight dimming bracket through the dimming bracket assembly 1, and at least one of the low beam module components can achieve fine-tuning and limiting of its vertical angle. It should be noted that the capacity of the mounting cavity should be slightly larger than the maximum radial dimension of the low beam module, so that there is still room for vertical angle adjustment after the low beam module is installed in the cavity.

[0033] like Figure 2 As shown, the dimming bracket assembly 1 includes a bracket body 101. A mounting post 102 is provided on the back of the bracket body 101. The mounting post 102 is preferably a cylindrical tube. A tension spring 103 is sleeved on the mounting post 102. When compressed, the tension spring 103 generates elastic force at both ends, acting as a stop. The tension spring 103 is preferably a high-force spring. A screw structure 104 is locked to the end of the mounting post 102. A set of rotating brackets 105 are symmetrically arranged on both sides of the mounting cavity of the bracket body 101.

[0034] Furthermore, such as Figure 3 The diagram shows a primary low beam module assembly of this embodiment. The primary low beam module assembly 2 includes a condenser 201, a lens bracket 202 mounted on the condenser 201, a lens structure 204 mounted on one side wall of the lens bracket 202, and a set of dimming shafts 203 symmetrically mounted on the outer wall. Each set of dimming shafts 203 is rotatably sleeved on a set of rotating brackets 105 on the bracket body 101, and the dimming shafts 203 and the rotating brackets 105 form a rotatable connection.

[0035] Furthermore, a heat sink 205 is included, with the condenser 201 mounted at its front end. A PCBA (Printed Circuit Board Assembly) 206 is electrically connected to the condenser 201. A connector 208 is provided at the bottom of the lens holder 202, which is sleeved on the end of the mounting post 102 and located behind the tension spring 103. A screw structure 104 passes through the connector 208 and locks the connector 208 and tension spring 103 onto the mounting post 102. Preferably, an upper bracket 207 is also provided at the top of the lens holder 202. The upper bracket 207 and the holder body 101 can be integrally formed, or the upper bracket 207 can be fixed to the inner wall of the holder body 101 by a snap-fit ​​method.

[0036] like Figure 4 and Figure 5 As shown, the dimming shaft 203 is sleeved on the rotating bracket 105, forming a rotational connection point. This allows the main low beam module assembly and / or the auxiliary low beam module 3 to be finely adjusted vertically within the cavity of the bracket around this connection point. After adjustment to the preset angle, the angle of the main low beam module assembly and / or the auxiliary low beam module 3 is limited by a limiting component. Specifically:

[0037] The connector 208 and the lens holder 202 are preferably integrally molded, but this is not limited here. In a preferred embodiment, the connector 208 is an annular structure with a central hole, and the mounting post 102 is a cylinder. In this case, the size of the hole in the connector 208 is adapted to the cylinder, and the inner diameter of the hole should be larger than the outer diameter of the mounting post 102.

[0038] The length of the tension spring 103 in its natural state is greater than the length of the mounting post 102, so that after the tension spring 103 is fitted onto the mounting post 102, part of the spring extends out of the mounting post 102. The connector 208 is fitted onto the tail of the mounting post 102, and its front end abuts against the tension spring 103 and is then pushed forward, pressing the tension spring 103 against the back of the bracket (the tension spring 103 and the connector 208 are in a mutually abutting relationship rather than a nested relationship).

[0039] The mounting post 102 has an axial mounting hole. The screw structure 104 passes through the sleeve hole and the mounting hole from the rear side of the connector 208 and is screwed into the mounting post 102 to fix the connector 208 and the tension spring 103 to the back of the bracket, and ensures that the tension spring 103 is in a compressed state. The force generated by the compression of the tension spring 103 acts on the bracket and the connector 208.

[0040] With the above structure, the low beam module can achieve fine-tuning of its vertical angle within the cavity of the bracket around the rotation connection point, and the angle of the low beam module is limited by the mounting post 102, the tension spring 103, the connector 208, and the screw structure 104. Since the connector 208 on the lens bracket 202 will undergo horizontal and vertical displacement as the low beam module rotates around the rotation connection point, the size of the hole on the connector 208 should provide sufficient space for this displacement to ensure that the limiting assembly as a whole can adapt to the angle changes of the module and undergo corresponding horizontal and vertical position changes. Furthermore, the tension spring 103 should have sufficient elasticity, which acts as a stopping force to relatively fix the connector 208 and the bracket, thereby ensuring that the limiting assembly has sufficient limiting capability.

[0041] In this application, the PCBA board is used to provide a controllable LED light source, and the lens is used to precisely control the light path. The two work together to achieve low beam lighting for vehicles, and heat dissipation can be achieved through the heat sink 205 during operation.

[0042] Working principle:

[0043] First, the dimming shaft 203 is sleeved on the rotating bracket 105, and the two form a rotating connection. This rotating connection limits the vertical and horizontal displacement of the low beam module, so that it can only rotate around the rotating connection point.

[0044] Tension spring 103 is sleeved onto mounting post 102, and then connector 208 is sleeved onto the rear side of tension spring 103, abutting against tension spring 103. Tension spring 103 is then locked onto mounting post 102 by screw structure 104. When screw structure 104 moves within mounting post 102, spring deforms, and the resulting elastic force acts as a stop for other components. Simultaneously, the tightness adjustment of connector 208 by screw structure 104 affects the rotation angle of dimming shaft 203 on rotating bracket 105. There are two sets of dimming shaft 203 and bracket 105, symmetrically arranged on both sides of the low beam module. Dimming shaft 203 and rotating bracket 105 serve as mechanical support points to support rotation, while the limiting component composed of mounting post 102, tension spring 103, connector 208, and screw structure 104 serves as a fixing and tightness adjustment structure, and also as a fixed point for adjusting the angle.

[0045] By screwing in or out the screw structure 104, the position of the connector 208 on the mounting post 102 is controlled, which drives the low beam module assembly to rotate around the rotation point formed by the dimming shaft 203 and the rotating bracket 105, thereby achieving fine adjustment of the up and down angle of the module. By adjusting the angle, this application can make up for the errors in product manufacturing and design, and adjust the light to the position required by the design, thereby effectively ensuring the relative position between the two low beam modules and improving the accuracy of the low beam cutoff line of the two modules.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
