Description

Technical Field

[0001] This utility model relates to the field of dashboard plastic parts installation technology, and in particular to a connection structure for automotive dashboard plastic parts. Background Technology

[0002] The car dashboard is a device that reflects the operating status of various vehicle systems. Common indicators include the fuel gauge, washer fluid gauge, electronic throttle indicator, front and rear fog light indicators, and warning lights.

[0003] The car dashboard is installed in the mounting position using connecting ears on plastic parts. The connecting ears have mounting holes and are fixed with screws. However, the current connecting ears are small, and the addition of holes greatly reduces the stress area, making them prone to breakage under external force. There is room for improvement. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a connection structure for plastic parts of automotive dashboards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A connecting structure for plastic parts of an automotive dashboard includes a pressure plate, a mounting block fixed to one side of the pressure plate, and two threaded holes symmetrically opened on the top of the mounting block. A slot is opened on the top of the mounting block, and a slot located below the slot is opened on the outer wall of the mounting block. A pressure plate is rotatably connected to the slot, and a gear is rotatably connected to the bottom of the pressure plate. The bottom of the gear is flush with the bottom of the mounting block. A limit stop is installed on the bottom of the gear, and a retaining clip is installed on the bottom of the pressure plate to limit the movement of the gear.

[0007] Preferably, a baffle is fixed to the top of the slot, and the baffle is arranged parallel to the pressing plate.

[0008] Preferably, the limiting stop includes a mounting plate, and two symmetrical stop arms are fixed to the outer wall of the mounting plate to block the rotation of the pressure plate.

[0009] Preferably, the gear is coaxially fixed with a screw head, and the mounting plate has a mounting hole for the screw head to pass through. The screw head is threaded with a nut, which can realize the installation and removal of the mounting plate.

[0010] Preferably, the locking element includes a limiting sleeve fixed to the bottom of the pressure plate, and a top head is slidably inserted inside the limiting sleeve. The end of the top head near the gear is configured as an arc-shaped end that matches the gear tooth groove.

[0011] Preferably, the bottom of the pressure plate is fixed with fixing ears on both sides near the top head. The fixing ears and the limiting sleeve are fixed by springs. This solution is equipped with gears and locking parts. The gears are detachably connected to the limiting stop, so that the limiting stop can be replaced and disassembled. In use, pulling the pull ring causes the top head to move inside the limiting sleeve. The spring located between the fixing ears and the limiting sleeve is compressed, releasing the restriction on the gear and facilitating the adjustment of the angle of the limiting stop. After being released, the top head can limit the gear under the action of the spring, achieving locking after adjustment.

[0012] Preferably, a pull ring is fixed at the end of the top head away from the limiting sleeve block, so as to facilitate pulling using the pull ring.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Due to the use of a pressure plate, mounting block, threaded hole, slot, pressure plate, limit stop, gear, and clamp, the mounting part on the plastic part is inserted into the slot. The pressure plate is rotated to cover the slot and resist the mounting part. The two stops on the mounting plate can make contact with the gap of the car mounting part, which enhances the installation stability of the pressure plate and mounting block. This effectively solves the problems mentioned in the background technology, and can stably install the pressure plate and mounting block. Then, the mounting part on the instrument panel plastic part is inserted into the slot for limit, which increases the contact area of ​​the mounting part of the instrument panel plastic part, so that it can withstand greater pressure. There is no need to drill holes in the already small mounting part, which would cause the problem of low load-bearing capacity.

[0015] 2. This solution includes gears and locking devices. The gears and limit stops are detachably connected, allowing the limit stops to be replaced and disassembled. In use, pulling the pull ring causes the top head to move within the limit sleeve. The spring located between the fixed ear and the limit sleeve is compressed, releasing its restriction on the gear and facilitating adjustment of the angle of the limit stop. After being released, the top head can limit the gear under the action of the spring, achieving locking after adjustment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A connecting structure for plastic parts of an automotive dashboard includes a pressure plate 1, a mounting block 2 fixed on one side of the pressure plate 1, and two threaded holes 3 symmetrically opened on the top of the mounting block 2. A slot 10 is opened on the top of the mounting block 2, and a slot 4 located below the slot 10 is opened on the outer wall of the mounting block 2. A pressure plate 5 is rotatably connected to the slot 10. A gear 6 is rotatably connected to the bottom of the pressure plate 1, and the bottom of the gear 6 is flush with the bottom of the mounting block 2. A limit stop 8 is installed on the bottom of the gear 6, and a retaining clip 7 is installed on the bottom of the pressure plate 1 to limit the gear 6.

[0023] In this utility model, a baffle 11 is fixed to the top of the slot 10, and the baffle 11 is arranged parallel to the pressing plate 5.

[0024] In this utility model, the limiting stop 8 includes a mounting plate 14, and two symmetrical stop arms 16 are fixed on the outer wall of the mounting plate 14 to block the pressure plate 5 when it rotates.

[0025] In this utility model, the gear 6 is coaxially fixed with a screw head 12, and the mounting plate 14 is provided with a mounting hole 15 for the screw head 12 to pass through. The screw head 12 is threadedly connected with a nut 13, which can realize the installation and disassembly of the mounting plate 14.

[0026] In this utility model, the clip 7 includes a limiting sleeve 17 fixed to the bottom of the pressure plate 1, and a top head 18 is slidably inserted inside the limiting sleeve 17. The end of the top head 18 near the gear 6 is set as an arc end that matches the tooth groove of the gear 6.

[0027] In this invention, the bottom of the pressure plate 1 is fixed with fixing ears 20 on both sides near the top head 18. The fixing ears 20 and the limiting sleeve block 17 are fixed by springs 21. This design includes a gear 6 and a locking piece 7. The gear 6 is detachably connected to the limiting stop 8, allowing the limiting stop 8 to be replaced and disassembled. In use, pulling the pull ring 19 causes the top head 18 to move within the limiting sleeve block 17. The spring 21 located between the fixing ears 20 and the limiting sleeve block 17 is compressed, releasing the restriction on the gear 6. This facilitates the adjustment of the angle of the limiting stop 8. After being released, the top head 18 can limit the gear 6 under the unfolding action of the spring 21, achieving locking after adjustment.

[0028] In this utility model, a pull ring 19 is fixed at the end of the top head 18 away from the limiting sleeve 17, so that it can be pulled by using the pull ring 19.

[0029] Working Principle: This instrument panel plastic component connection structure employs a pressure plate 1, mounting block 2, threaded hole 3, slot 4, pressure plate 5, limiting stop 8, gear 6, and clamp 7. When using this connection structure, the mounting part on the plastic component is inserted into the slot 4. The pressure plate 5 is rotated to cover the slot 4, providing support for the mounting component. The outer wall of the plastic component fits against the outer wall of the mounting block 2. Screws are passed through the threaded hole 3 to install the mounting block 2 and pressure plate 1 in the installation position. Then, by rotating the limiting stop 8, the two stops 16 on the mounting plate 14 can make contact with the gaps in the vehicle's mounting parts, enhancing the stability of the pressure plate 1 and mounting block 2 installation. This effectively solves the problems raised in the background technology, ensuring stable installation of the pressure plate 1 and mounting block 2. The insertion of the mounting component on the instrument panel plastic component into the slot 4 for limiting increases the contact area of ​​the mounting component, allowing it to withstand greater pressure. This eliminates the need for drilling holes in the already small mounting component, preventing issues with low load-bearing capacity.
