Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a dual-module flexible switching joint debugging structure and system for vehicles. Background Technology

[0002] With the rapid development of the automotive industry, people's requirements for car lights are no longer limited to basic lighting functions, but also require them to have characteristics such as beautiful light patterns and precise dimming. This points the way for the future development of dual-module car lights.

[0003] To better meet the high standards of lighting performance, miniaturization, simplification, and precision of dimming structures have become key research areas for dual-module vehicle lights. In existing technologies, to achieve dimming functionality in dual-module vehicle lights, multiple motors are typically used to achieve independent or joint adjustment of the two modules via ball joints, brackets, and other related structures. However, the independent adjustment scheme for the two modules cannot achieve synchronous movement. Existing technologies for joint adjustment of the two modules use an integrated adjustment bracket to transmit the driving force of the drive motor to the dimming points of the two modules (e.g., patent number CN218268859U). Firstly, the integrated adjustment bracket requires high precision in the installation positions of the two modules; otherwise, mismatch may occur. Secondly, the selection of module dimming points is limited by the structure; some locations may be unsuitable for dimming points due to interference issues. Furthermore, the integrated adjustment bracket cannot adjust the dimming points according to different module structures, necessitating the replacement of the entire adjustment bracket and increasing dimming costs.

[0004] In addition, in the existing ESC structure, the drive motor is directly connected to the adjustment bracket or adjustment screw. When the motor works for the same amount of time, it can only achieve the rotation of the module at a fixed angle, and cannot be adjusted according to the different size of the module and the dimming accuracy requirements. Utility Model Content

[0005] To address the technical problems of existing dimming structures being unable to achieve synchronous movement of two modules or flexibly adjust the dimming point, this utility model provides a vehicle-use dual-module flexible switching joint adjustment structure and system to solve the above problems.

[0006] This utility model proposes a dual-module flexible switching joint adjustment structure for vehicles, including a drive component, an intermediate transmission group, and transmission rods. The output end of the drive component is connected to a primary transmission component. The intermediate transmission group is provided in two sets, which are respectively connected to the primary transmission components. There are two transmission rods, one end of which is hinged to the dimming point of the two module seats respectively, and the other end is connected to the intermediate transmission group one by one. Each module seat has a rotation origin, and the lines connecting the dimming point and the rotation origin in the two module seats are parallel to each other.

[0007] In an optional embodiment of this utility model, the primary transmission component is a rack, the intermediate transmission group is a single-stage or multi-stage gear group, and the end of the transmission rod that meshes with the intermediate transmission group is provided with a rack.

[0008] In an optional embodiment of this utility model, both intermediate transmission groups include an even number of meshing gears, and the dimming points in the two module seats are located on the same side of their respective rotation origins.

[0009] In an optional embodiment of this invention, the diameters of the gears in each intermediate transmission group are not exactly equal.

[0010] In an optional embodiment of this invention, both intermediate transmission assemblies include two meshing gears.

[0011] In an optional embodiment of this utility model, one of the intermediate transmission groups includes an even number of meshing gears, and the other intermediate transmission group includes an odd number of meshing gears, with the dimming points in the two module seats located on different sides of their respective rotation origins.

[0012] In an optional embodiment of this utility model, the dimming point is located at the top corner of the module base.

[0013] In an optional embodiment of this utility model, one end of the transmission rod connecting module seat is provided with a ball head screw.

[0014] In an optional embodiment of this utility model, the driving component includes a drive motor and a dimming screw connected to the drive motor, wherein the drive motor and the dimming screw respectively drive the primary transmission component to perform reciprocating linear motion.

[0015] This utility model also proposes a joint debugging system, including two module bases and two flipping components. The two flipping components include an up-and-down flipping component and a left-and-right flipping component. The up-and-down flipping component drives the two module bases to flip up and down synchronously, and the left-and-right flipping component drives the two module bases to flip left and right synchronously. At least one of the flipping components is the vehicle dual-module flexible switching joint debugging structure described above.

[0016] The beneficial effects of this utility model are:

[0017] (1) The dual-module flexible switching joint adjustment structure for vehicles described in this utility model divides the overall joint adjustment bracket in the prior art into two independent transmission rods, and connects the two transmission rods to the same driving component through an intermediate transmission group to achieve synchronous driving of the two modules. When it is necessary to switch the dimming point, only the corresponding intermediate transmission group or transmission rod needs to be adjusted, without the need to replace the entire part, thus reducing the cost of dimming for different products. In addition, the assembly restrictions between the two modules disappear during installation, and the installation accuracy requirements are reduced.

[0018] (2) The present invention uses gear meshing to form an intermediate transmission group, which can select an appropriate number of gears for meshing according to the actual distance and step size requirements, and has a high degree of adjustment flexibility. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1

[0026] like Figure 1 and Figure 2 As shown, a vehicle-mounted dual-module flexible switching and adjustment structure includes a drive unit 4, an intermediate transmission group 5, and transmission rods 6. The output end of the drive unit 4 is connected to a primary transmission unit 7. Two intermediate transmission groups 5 are provided, each connected to the primary transmission group 7. Two transmission rods 6 are provided, one end of which is hinged to a dimming point on each of the two module seats 3, and the other end is connected to the intermediate transmission group 5 respectively. The drive unit 4 outputs linear motion, which is transmitted to the two transmission rods 6 through the intermediate transmission groups 5 on both sides. The two transmission rods 6 respectively drive the two module seats 3 to rotate. Ball-head screws 10 are provided at the ends of the transmission rods 6, allowing the connection between the transmission rod 6 and the module seat 3 to be adjusted at any angle.

[0027] Each module base 3 has a rotation origin 8, and the lines connecting the dimming point and the rotation origin 8 in the two module bases 3 are parallel to each other. When the drive unit 4 is activated, the two module bases 3 can rotate along two parallel rotation axes, realizing synchronous up-down or synchronous left-right flipping of the two module bases 3. The dimming point is usually located at the top corner of the module base 3.

[0028] The primary transmission component 7, the intermediate transmission group 5, and the transmission rod 6 drive in sequence. Compared with the existing structure that is directly fixed to the drive motor 401, the structure of this utility model has better flexibility and the components can be adjusted according to the actual position requirements.

[0029] For example, Figure 2 As shown, both transmission rods 6 are hinged to the two module seats 3 at the dimming point in the lower left corner, while Figure 3 The two transmission rods 6 are hinged to the two module seats 3 at the lower left and lower right dimming points, respectively. This is because dimming points may not be able to be arranged in some areas of the module seat 3 due to structural interference. When different dimming points are selected, the distance between the two dimming points changes, and the distance between the two transmission rods 6 and the drive component 4 also changes. This allows for structural adjustment by adjusting individual components, usually by adjusting the intermediate transmission group 5.

[0030] Transmission method:

[0031] The transmission method can be gear transmission, lead screw and nut transmission, etc.

[0032] In this embodiment, the primary transmission component 7 is a rack, the intermediate transmission group 5 is a set of one or more gears 14, and the end of the transmission rod 6 that meshes with the intermediate transmission group 5 is provided with a rack 9.

[0033] The intermediate transmission group 5 can contain one or more gears 14. When there is only one gear 14, the movement distance of the primary transmission component 7 is the same as that of the transmission rod 6. When there are multiple gears 14, and the diameters of the gears 14 are not exactly equal, the movement distance of the primary transmission component 7 is different from that of the transmission rod 6. In this case, different flipping ranges and flipping accuracies of the module base 3 can be achieved using the same drive component 4. The intermediate transmission group 5 shown in the figure consists of two gears 14 of unequal size.

[0034] Regarding the configuration of the two intermediate transmission groups 5:

[0035] The number of gears 14 affects the direction of movement of the transmission rod 6, that is, the direction of rotation of the module base 3. When the number of gears 14 in the intermediate transmission group 5 is odd, the direction of movement of the transmission rod 6 is opposite to the direction of movement of the primary transmission component 7. When the number of gears 14 in the intermediate transmission group 5 is even, the direction of movement of the transmission rod 6 is the same as the direction of movement of the primary transmission component 7.

[0036] When the dimming points in both module bases 3 are located on the same side of their respective rotation origins 8 (e.g.) Figure 3 As shown), the two transmission rods 6 need to move in the same direction to achieve the same-direction flipping of the module base 3. Therefore, at this time, the number of odd and even gears 14 in the two intermediate transmission groups 5 is the same. In this embodiment, it is preferred that the number of gears 14 is even, specifically two. This is so that the step size can be changed through the design of the large and small gears 14.

[0037] When the dimming points in the two module holders 3 are located on different sides of their respective rotation origins 8 (e.g.) Figure 2 As shown in the figure, the two transmission rods 6 need to move in different directions to achieve the same-direction flipping of the module base 3. Therefore, the number of odd and even gears 14 in the two intermediate transmission groups 5 is different. That is, one intermediate transmission group 5 includes an even number of meshing gears 14, and the other intermediate transmission group 5 includes an odd number of meshing gears 14. As shown in the figure, the left intermediate transmission group 5 has two gears 14, and the right intermediate transmission group 5 has three gears 14.

[0038] The drive unit 4 can be a linear motor.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is that the driving component 4 includes a drive motor 401 and a dimming screw 402 connected to the drive motor 401. The drive motor 401 and the dimming screw 402 respectively drive the primary transmission component 7 to perform reciprocating linear motion. When electronic adjustment is required, the drive motor 401 is used for adjustment; when manual adjustment is required, the dimming screw 402 is used for adjustment. The specific structure is similar to the third adjustment mechanism in patent number CN218268859U.

[0041] Example 3

[0042] A joint debugging system includes two module bases 3 and two flipping components. The two flipping components include an up-down flipping component 1 and a left-right flipping component 2. The up-down flipping component 1 drives the two module bases 3 to flip up and down synchronously, and the left-right flipping component 2 drives the two module bases 3 to flip left and right synchronously. At least one of the flipping components is the vehicle dual-module flexible switching joint debugging structure described above.

[0043] For ease of description, the dimming point connecting the two module bases 3 to the vertical flip component 1 is named vertical dimming point 11, and the dimming point connecting the two module bases 3 to the horizontal flip component 2 is named horizontal dimming point 12. Within the same module base 3, the line connecting the vertical dimming point 11 to its corresponding rotation origin 8 forms the vertical flip rotation axis, and the line connecting the horizontal dimming point 12 to its corresponding rotation origin 8 forms the horizontal flip rotation axis. The vertical flip rotation axis and the horizontal flip rotation axis are perpendicular to each other.

[0044] In this embodiment, the left-right flipping component 2 adopts the vehicle dual-module flexible switching joint debugging structure described in this utility model, and the up-down flipping component 1 adopts the joint debugging bracket 13 in the prior art as an example for illustration.

[0045] like Figure 3 In the integrated adjustment system shown, the two left and right dimming points 12 are located at the lower left corner of the module base 3, and the two up and down dimming points 11 are located at the upper right corner of the module base 3. Figure 2 In the aforementioned integrated adjustment system, the left and right dimming points 12 of the left module base 3 are located at the lower left corner of the module base 3, the left and right dimming points 12 of the right module base 3 are located at the lower right corner of the module base 3, the upper and lower dimming points 11 of the left module base 3 are located at the upper right corner of the module base 3, and the upper and lower dimming points 11 of the right module base 3 are located at the upper left corner of the module base 3. The positional variation of the upper and lower dimming points 11 is to avoid the left and right dimming points 12 and prevent structural crowding within the same module base 3. For the upper and lower flip assembly 1, the positional variation of the dimming points does not affect the flipping direction; therefore, the integrated adjustment bracket 13 can be used. For the left and right flip assembly 2, the positional variation of the dimming points will cause the flipping to reverse; therefore, the flipping direction adjustment needs to be achieved through the intermediate transmission group 5.

[0046] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0047] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
