Description

Technical Field

[0001] This utility model relates to the field of automotive cockpit assembly technology, specifically to a modular quick-release structure and an automotive cockpit. Background Technology

[0002] Currently, the dashboard in a car cabin consists of a semi-assembly structure, side trim panels, a wireless charging module, and wiring harnesses. These components are supplied to the OEM for final assembly as separate parts. The assembly process involves four steps: first, assembling the semi-assembly parts; second, securing the semi-finished product to the vehicle frame with multiple bolts; third, connecting to the vehicle's wiring harness to complete the circuit installation; and finally, sealing the entire assembly by installing the side trim panels into the semi-assembly structure. This assembly process requires at least two operators working together, making it cumbersome, time-consuming, and labor-intensive. The current installation structure and assembly process are no longer suitable for the requirements of intelligent production lines that demand simplified single-person processes and shorter operating times. There is a need for an integrated quick-assembly and disassembly structure that allows the sub-dashboard to be supplied directly to the OEM as a complete assembly, completely eliminating the bolt locking and step-by-step assembly process, thus meeting the flexibility and efficiency requirements of intelligent production lines. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Example 1 like Figures 1-6 As shown, this embodiment discloses a combined quick-release structure, including a housing 800, a first support member 301, a pin 302, a limiting spring plate 303, and a first fastener 304. The housing 800 has a cavity for installing instruments and other functional components. The cavity penetrates the bottom wall of the housing 800 to form an opening. The first support member 301 is located at the opening of the housing 800, serving to support the housing 800. The upper surface of the first support member 301 near both ends has fixing holes 3011. The pin 302 is located within the fixing holes 3011. One end of the limiting spring plate 303 is fixed to the first support member 301 by the first fastener 304. The pin 302 penetrates the other end of the limiting spring plate 303, and the limiting spring plate 303 abuts against the pin 302, applying a spring force towards the bottom surface of the first support member 301 to the pin 302, thus fixing the position of the pin 302 and preventing it from being subjected to external forces. The device allows for stable sliding after pressing, preventing shaking during assembly. It also includes a locking device 400, which is located on the inner wall of the housing 800 and is engaged with the first support member 301. The locking device 400 includes a second support member 401, a latch 406, a locking pin 404, and a spring member 405. The second support member 401 is located on the inner wall of the housing 800, the latch 406 is located on the second support member 401, the locking pin 404 is slidably connected to the second support member 401, and the spring member 405 is sleeved on the locking pin 404 for resetting the locking pin 404. The first support member 301 has a slot 307, in which the locking pin 404 can be engaged to prevent the movement of the pin 302. The combination of the locking device 400 and the pin 302 on the first support member 301 allows the housing 800 to be quickly snapped together and locked in place, enabling quick assembly and disassembly by a single person.

[0021] Furthermore, the pin 302 and the first support member 301 are formed in one piece. The middle part of the pin 302 slides in conjunction with the fixing hole 3011. The pin 302 can move within a small range in the fixing hole 3011, leaving enough installation space for insertion into the locking hole 604 during installation, reducing the difficulty of docking during installation. The upper part of the fixing hole 3011 is provided with a shield, so the pin 302 cannot be exposed from the top, preventing the pin 302 from entering the housing 800 and damaging the internal instrument components.

[0022] Furthermore, the latch 406 includes a sliding latch 402, a limiting member 403, and a second fastener 407. A slot is provided on one side wall of the housing 800, and the limiting member 403 is disposed at the slot. The limiting member 403 has a limiting groove, and part of the sliding latch 402 is slidably connected in the limiting groove. The sliding latch 402 is connected to the locking pin 404 and can drag the locking pin 404 to slide up and down. The second fastener 407 fixes the limiting member 403 to the housing 800. Specifically, the lower part of the sliding latch 402 has a stop. When the locking pin 404 falls into the stop, pushing the sliding latch 402 can drive the locking pin 404 to move upward to unlock. The elastic member 405 provides the elastic force for the locking pin 404 to return downward. Part of the sliding latch 402 protrudes from the limiting groove to form a sliding fit, which facilitates the external pushing of the sliding latch 402 to unlock. The limiting member 403 serves to limit the sliding latch 402 and cover the slot.

[0023] Furthermore, the pin 302 includes a fixed head, a rotating rod, and a tail. The two ends of the rotating rod are connected to the fixed head and the tail, respectively. The diameter of the tail is larger than that of the rotating rod. The rotating rod is clearance-fitted with the fixed hole 3011. The cross-section of the fixed head is tapered, which can guide the pin 302 into the fixed hole 3011.

[0024] Preferably, the first support member 301 has a guide portion in the middle, which is formed by the downward indentation of the upper end surface of the first support member 301. The guide portion is in contact with the surface of the support member 602 and plays a supporting and guiding role. Both ends of the first support member 301 are higher than the guide portion, leaving space for sliding assembly.

[0025] Preferably, a wire harness plug-in terminal 501 is provided on the lower end surface of the first support member 301. The cable on the wire harness plug-in terminal 501 penetrates the first support member 301 and is connected to the cable inside the instrument. When a snap-fit ​​is formed, the wire harness plug-in terminal 501 is connected at the same time, which simplifies the structure and reduces the assembly steps.

[0026] Furthermore, it also includes a support member 602, which is slidably connected to the first support member 301. The support member 602 is provided with a locking hole 604, and the pin 302 falls into the locking hole 604 to form a locking, restricting the first support member 301 from moving up and down. The support member 602 contacts the first support member 301 and provides support for the first support member 301 to bear the weight of the cockpit components.

[0027] Preferably, the cross-section of the support member 602 is designed to be arc-shaped, with a concave center and protruding sides, and the support member 602 is directly fixed to the vehicle frame.

[0028] Preferably, the locking hole 604 is a slot, with the diameter of one end of the slot being larger than that of the other end. After the pin 302 is inserted into the slot, it slides along the direction of the slot to form a locking connection. This, together with the locking device 400, forms a locking connection. This makes disassembly and assembly convenient and less prone to damage even after repeated disassembly and assembly, facilitating subsequent maintenance and use.

[0029] Preferably, the support member 602 has guide grooves 605 in the middle of both sides, and a wire harness head 603 is provided in the guide groove 605. The wire harness head 603 is telescopically connected in the guide groove 605 and is inserted into the wire harness plug terminal 501. After the wire harness head 603 is connected to the wire harness plug terminal 501, it can telescopically move with the sliding of the wire harness plug terminal 501 to prevent the cable from being squeezed. It is used in conjunction with the first support member 301 and the support member 602 for sliding engagement.

[0030] More preferably, it also includes a release lever 601, which is movably connected to the locking device 400 to limit the movement of the limiting member 403. The release lever 601 is inserted after the sliding buckle 402 is pushed up to prevent the sliding buckle 402 from automatically descending, and is used by a single person for disassembly and assembly.

[0031] In another embodiment, the opening of the housing 800 is provided with a combination quick-release structure on both the left and right sides. The two quick-release structures are arranged opposite each other along the middle surface of the housing 800 and are used to fix the two sides of the housing 800 respectively. This can be used for the installation of large-sized housings 800.

[0032] See Figure 6 The usage process of this modular quick-release structure is as follows: During assembly, connect the housing 800 containing the instrument parts to the first support member 301, and simultaneously connect the cable to the inward-facing portion of the wire harness connector 501. Hold the housing 800 and bring the guide portion on the first support member 301 into contact with the support member 602, causing the pin 302 to fall into the locking hole 604. Insert the wire harness head 603 into the wire harness connector 501, and push the housing 800 along the length of the support member 602 until the latch 406 enters the slot 307, blocking the movement space of the pin 302 in the locking hole 604, thus completing the installation. To remove, push the latch 406 upward and insert the release lever 601, then push along the length of the support member 602 to disengage the pin 302 from the locking hole 604. At the same time, release the wire harness head 603 and the wire harness connector 501, and the housing 800 can be removed.

[0033] Example 2 This embodiment also discloses an automotive cockpit, including a modular quick-release structure. The housing 800 of the modular quick-release structure contains an instrument assembly 700. The instrument assembly 700 is fixed to the cockpit through the modular quick-release structure, thereby achieving rapid installation of the instrument components.

[0034] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
