Description

Technical Field

[0001] The utility model relates to the field of vehicle ceiling lights, in particular to a vehicle ceiling light assembly with an integrated microphone and a vehicle. Background Art

[0002] like Figure 1 , Figure 2 As shown, in the vehicle ceiling lights with integrated microphones on the existing market, the microphone is generally used as an independent small assembly. The microphone assembly usually includes a base, a microphone module and a cover plate. The microphone module needs the base and the cover plate to form a shell as a support and fixation. The microphone assembly is usually installed on the outside of the main substrate of the vehicle ceiling light. In this way, not only a separate microphone mounting position is required outside the main substrate, but also the microphone assembly needs to be connected to the main substrate of the vehicle ceiling light with a wiring harness and a connector. The dedicated mounting position not only takes up space, but also requires a separate microphone shell, wiring harness and connector, resulting in a waste of space and an increase in cost. Summary of the invention

[0003] In order to avoid the shortcomings of the background technology, the utility model provides a vehicle ceiling light assembly with an integrated microphone and a vehicle, which can save some parts and reduce costs.

[0004] The vehicle ceiling light assembly with an integrated microphone proposed in the utility model comprises a shell, a main control circuit board, a fixing seat and a panel, wherein a plurality of functional modules electrically connected to the main control circuit board are fixedly arranged on the fixing seat, wherein the functional modules comprise a microphone module, wherein the microphone module comprises a microphone circuit board, and the microphone circuit board has two contact ends on its surface facing the main control circuit board; two conductive springs are further arranged between the main control circuit board and the microphone circuit board, wherein the conductive springs comprise a fixing portion, a deformation portion and a contact portion, wherein the fixing portion is used for fixing and connecting with the main control circuit board, and the contact portion is used for contacting and connecting with the contact end of the microphone circuit board; when the conductive spring is in a free state, the top position of the contact portion exceeds the position of the microphone circuit board; when the microphone module is fixedly mounted on the fixing seat, the conductive spring is in a compressed and deformed state and the contact portion is in contact and connected with the contact end of the microphone circuit board; the microphone module is connected to the circuit of the main control circuit board through the conductive spring.

[0005] Furthermore, the contact portion is arc-shaped as a whole, and the contact end is rectangular.

[0006] Furthermore, the width of the contact end is greater than the width of the conductive spring.

[0007] Furthermore, the microphone module also includes a microphone functional unit; the panel is provided with a plurality of sound collection holes, and the sound collection holes correspond to the positions of the microphone functional unit.

[0008] The utility model also provides a vehicle, comprising the vehicle ceiling light assembly with integrated microphone as described above.

[0009] The beneficial effect of the present invention is that compared with the microphone solution in the vehicle ceiling light of the background technology, the shell, wiring harness, connecting terminals and other parts of the microphone assembly are eliminated, which not only reduces the material cost and manufacturing cost as a whole, but also improves the assembly efficiency and saves labor costs due to the reduction of parts. What is more important is that there is no need to design a special mounting position on the outside of the main control circuit board, which saves space and is conducive to the miniaturization design of the microphone.

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] For example, see the attached Figure 3-6, a vehicle ceiling light assembly with an integrated microphone, which includes a housing 10, a main control circuit board 20, a fixing seat 30 and a panel 50 in order from top to bottom. The fixing seat 30 is fixed with a plurality of functional modules electrically connected to the main control circuit board 20. The types of functional modules are placed according to needs. Generally, buttons and lights are necessary in a vehicle ceiling light, so a button module and a light guide module can be arranged on the fixing seat 30; in this embodiment, since the vehicle ceiling light assembly is integrated with a microphone, the functional module also includes a microphone module 40, and the microphone module 40 includes a microphone circuit board 41. The microphone circuit board 41 has two contact ends 411 on its surface facing the main control circuit board 20; two contact ends 411 are also arranged between the main circuit board 20 and the microphone circuit board 41 A conductive spring piece 60 includes a fixing portion 61, a deformation portion 62 and a contact portion 63; the fixing portion 61 is used for fixing and connecting with the main control circuit board 20, and is usually fixed by a soldering process; the contact portion 63 is used for contacting and connecting with the contact end 411 of the microphone circuit board 41; when the conductive spring piece 60 is in a free state, the top position of the contact portion 63 exceeds the position of the microphone circuit board 41; when the microphone module 40 is fixedly installed on the fixing seat 30, the microphone module 40 applies pressure to the conductive spring piece 60 to deform it, thereby making the conductive spring piece 60 in a compressed and deformed state and the contact portion 63 is in contact and connected with the contact end 411 of the microphone circuit board 41; the microphone module 40 is connected to the circuit of the main control circuit board 20 through the conductive spring piece 60.

[0018] Compared with the microphone solution in the vehicle ceiling light of the background technology, in the vehicle ceiling light assembly with integrated microphone in this embodiment, only the functional part in the microphone assembly is retained, and the microphone module 40 is fixed by the existing fixing seat 30 and panel 50 in the ceiling light, eliminating the shell 10 of the microphone assembly, thereby reducing the cost. In addition, in this embodiment, a special power connection method is set between the microphone circuit board 41 and the main control circuit board 20, that is, the connection is made by the conductive spring 60, and electronic components such as wiring harness and connecting terminals are no longer required. Since the conductive spring 60 is a stamping part that is easy to manufacture, the cost of the conductive spring 60 is much lower than the cost of electronic components such as wiring harness and connecting terminals. Therefore, not only the material cost and production cost are reduced, but the reduction of parts and components also improves the assembly efficiency and saves labor costs; more importantly, there is no need to design a special mounting position on the outside of the main control circuit board 20, which saves space and is conducive to the miniaturization of the microphone design.

[0019] Considering that the conductive spring 60 is formed by stamping, the size tolerance and shape tolerance of the part after forming are large, and the fixing part 61 of the conductive spring 60 is fixed to the main control circuit board 20 by soldering process. Although the positional relationship between the two can be ensured by welding tooling, there is still a large positional tolerance. Therefore, these various factors lead to a large matching tolerance between the microphone circuit board 41 and the conductive spring 60. Specifically, the connection point position of the microphone circuit board 41 and the contact part 63 of the conductive spring 60 in different vehicle ceiling lights will vary greatly. In order to ensure contact matching, the contact part 63 of the conductive spring 60 in this embodiment is arc-shaped as a whole. The arc-shaped contact part 63 can ensure that no matter how large the matching tolerance is, as long as the microphone circuit board 41 can apply force to the conductive spring 60 to make it in a compressed and deformed state, the contact part 63 of the conductive spring 60 can form a line contact with the microphone circuit board 41; correspondingly, the contact end 411 of the microphone circuit board 41 is rectangular, and the rectangular contact end 411 can adapt to the position change of the line contact.

[0020] In addition, in this embodiment, the width of the contact end 411 of the microphone circuit board 41 is greater than the width of the conductive spring 60. For a circuit board, the exposed contact end 411 is generally slightly lower than the solder resist layer. In order to prevent the contact portion 63 of the conductive spring 60 from contacting the solder resist layer and causing poor contact, the width of the contact end 411 of the microphone circuit board 41 needs to be set larger.

[0021] In this embodiment, the microphone module 40 further includes a microphone functional unit 42 ; a plurality of sound collecting holes 51 are provided on the panel 50 , and the positions of the sound collecting holes 51 correspond to those of the microphone functional unit 42 , so that the collected sound quality is clearer.

[0022] Although the present invention has been described with reference to preferred embodiments, it should be understood by those skilled in the art that it is not limited to the description of the above embodiments and that various changes in form and details may be made within the scope of the claims.
