Description

Technical Field

[0001] The invention belongs to the field of automobile accessories, and in particular relates to a pre-installed latch pressing mechanism. Background Art

[0002] In the prior art, the clamping mechanism for fixing the electrical module of a passenger car or commercial vehicle to the instrument panel or sub-instrument panel is to use a pressing plate to directly press on the electrical module and install it on the vehicle assembly line.

[0003] That is to say, the pressure plate is a separate component, which needs to be produced and transported separately, which will increase a lot of installation costs and management costs.

[0004] When there are too many parts, it is easy for some to be missed during the installation process, which will result in missing parts on the dashboard or sub-dashboard.

[0005] In addition, separate pressure plates are particularly difficult to store and manage. The parts are small and need to be loaded and shipped separately. The additional assembly parts increase transportation and management costs. During the installation process, there is no specific installation location on the dashboard or sub-dashboard, and installation must be done manually. Each installation is random, and there is a problem of unreliable installation. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a pre-installed latch clamping mechanism to solve the problems that the existing pressing plates are separate, require separate management and separate installation, are unstable during installation, have high transportation and management costs, and are complex to install.

[0007] The present invention is achieved through the following technical solutions.

[0008] A pre-installed latch clamping mechanism includes an electrical support, the electrical support is fixed on the instrument panel body, the electrical support is provided with two parallel bar blocks, a receiving cavity is formed between the bar blocks and the electrical support, a slidable latch is placed in the receiving cavity, the electrical support is also provided with an electrical module installation position, the electrical module installation position is located on one side of the latch, an electrical module can be placed on the electrical module installation position, a threaded through hole is provided on the latch, a bolt hole is provided on the electrical support, when the threaded through hole is aligned with the bolt hole, the bolt can be screwed in, and a stop device that can limit the position of the latch is provided on the bar block. The original multi-parts mode is changed, pre-installation is performed, and later maintenance and installation are reduced, and the stability after installation is greatly improved, and the noise is small.

[0009] Preferably, the latch is provided with a protrusion, and the protrusion is bonded with felt, which can further reduce installation noise.

[0010] Preferably, the upper and lower ends of the latch are provided with first and second limiting ribs, which play the role of fixing the initial position and stopping the latch in the later stage.

[0011] Preferably, a notch is provided above the left strip plug, the two side surfaces of the strip plug are vertical surfaces, the cross section of the first limiting rib is triangular, and the cross section of the second limiting rib is trapezoidal. Integral injection molding reduces the cost of parts.

[0012] Preferably, the electrical module is provided with a notch, and the protrusion on the latch can be pressed into the notch. The latch presses the electrical module to prevent it from escaping or being misplaced.

[0013] Compared with the prior art: the latch is pre-set on the electrical bracket, and the latch can be pre-installed into the electrical bracket by the supplier for integrated supply, saving transportation and management costs. The structure is simple, has good strength, is easy to operate on the vehicle assembly line, saves operation time, and thus reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A pre-installed latch clamping mechanism includes an electrical support 6, the electrical support 6 is fixed on an instrument panel body 7, two parallel bar-shaped plug blocks 1 are arranged on the electrical support 6, a receiving cavity is formed between the bar-shaped plug block 1 and the electrical support 6, a slidable latch 4 is placed in the receiving cavity, the electrical support 6 is also provided with an electrical module installation position, the electrical module installation position is located on one side of the latch 4, an electrical module 2 can be placed on the electrical module installation position, a threaded through hole is opened on the latch 4, and a bolt hole is provided on the electrical support 6. When the thread When the through hole is aligned with the bolt hole, the bolt can be screwed in. A shifting device that can limit the position of the pin 4 is provided on the strip plug block 1. A protrusion is provided on the pin 4. A felt 3 is bonded to the outside of the protrusion. A first limiting rib 9 and a second limiting rib 8 are provided at the upper and lower ends of the pin 4. A notch 10 is provided above the left strip plug block 1. The two side surfaces of the strip plug block 1 are vertical surfaces. The cross-section of the first limiting rib 9 is triangular, and the cross-section of the second limiting rib 8 is trapezoidal. A notch is provided on the electrical module 2, and the protrusion on the pin 4 can be pressed into the notch.

[0022] During use, the felt 3 is first pasted onto the protrusion of the latch 4, and the latch 4 is inserted as a whole into the accommodating cavity formed between the strip plug 1 and the electrical bracket 6. The electrical bracket 6 assembly is pre-installed on the dashboard body 7 through 5 bolts and supplied to the vehicle manufacturer in an integrated manner.

[0023] In the initial state, the latch 4 is located on the left side, as shown in Figures AA (1) and BB (1), the first limiting rib 9 is located in the notch 10, the cross section of the first limiting rib 9 is triangular, and the latch is locked to prevent disassembly, displacement or falling off during transportation;

[0024] When arriving at the vehicle manufacturer's location, the vehicle manufacturer first installs the instrument panel body 7 assembly on the vehicle body; then installs the electrical module 2 to the electrical module installation position, and then pushes the latch 4 to the right to the position shown in Figures AA (2) and BB (2). The first limiting rib 9 of the latch 4 is located on the right vertical surface of the strip plug 1 on the left to prevent it from falling back. The second limiting rib 8 of the latch 4 moves to the left vertical surface of the strip plug 1 on the right, and the vertical surface of the second limiting rib 8 is close to the left vertical surface of the strip plug 1 on the right, which can play a role in pushing it into place. When it is pushed manually, it gets stuck at this position and cannot be pushed anymore, so it stops. At this time, the bolt hole set on the electrical bracket 6 is aligned with the threaded hole on the latch 4, and a bolt or screw can be screwed in to lock it.

[0025] The device is very clever. The latch 4 is pre-set on the electrical bracket, and the latch can be pre-installed in the electrical bracket by the supplier for integrated supply, saving transportation and management costs. The structure is simple, the strength is good, and the vehicle assembly line is easy to operate, saving operation time, thereby reducing costs.

[0026] Moreover, after the latch 4 moves into place, it can be blocked by the strip plug 1 on the right and the second limiting rib 8, and the first limiting rib 9 is located on the right vertical surface of the strip plug 1 on the left to prevent backward movement and shaking, with good overall stability and low noise.

[0027] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
