Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile bodies, in particular to a slidable mounting structure for a door lock catch of an automobile cab. Background Art
[0002] In the current technical field of vehicle body manufacturing, common door lock catch mounting solutions are as Figure 1-2 shown, in which the screw connection plate of the door lock catch is designed to be movable within a box-shaped structure or a limit plate. This design aims to allow a certain degree of position adjustment to better cooperate with the door lock. However, this solution has obvious defects: due to the mobility of the screw connection plate, it may not fit closely with the vehicle body B-pillar, and even misalignment may occur (as Figure 2 shown). This not only increases the difficulty during the assembly process but also may cause the door lock catch to be not properly installed. More critically, vibrations during vehicle driving and impact forces when closing the door may further loosen or detach the already unstable door lock catch, thus affecting the normal function of the door and potentially threatening the safety of the occupants. Summary of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the utility model provides a slidable mounting structure for a door lock catch of an automobile cab to solve the problems raised in the above background art.
[0004] To achieve the above object, the utility model adopts the following technical solutions:
[0005] A slidable mounting structure for a door lock catch of an automobile cab includes a side panel, a B-pillar, a screw connection plate of the door lock catch, and a clamping piece. The side panel is provided with a B-pillar. The fixing part of the clamping piece is fixed inside the B-pillar. The clamping parts of the two clamping pieces fix the screw connection plate of the door lock catch on the B-pillar. Circular holes are provided on both sides of the screw connection plate of the door lock catch. Convex bumps are provided on the clamping parts of the clamping piece, and the convex bumps are located within the circular holes, enabling the screw connection plate of the door lock catch to slide within the range of the clamping piece.
[0006] Preferably, the clamping piece is an elastic clamping piece, and the elastic pressing of the clamping piece causes the screw connection plate of the door lock catch to fit with the B-pillar.
[0007] Preferably, the screw connection plate of the door lock catch is provided with a lug, and the side panel is provided with a notch.
[0008] Preferably, the number of the circular holes is two.
[0009] Preferably, the number of the convex bumps of the clamping piece is one.
[0010] The utility model has the following beneficial effects compared with the prior art:
[0011] 1. Structural simplicity: This new utility model design ingeniously meets the adjustment requirements during the assembly of the door lock catch and the vehicle door lock by introducing a door lock catch screw connection plate with round holes and complementing it with an innovative combination of elastic clamping pieces. This design not only significantly reduces the weight of the overall structure but also simplifies the manufacturing process, remarkably lowering the production difficulty, fully meeting the strict requirements of the current automotive industry for green and energy-saving products.
[0012] 2. High reliability guarantee: Compared with traditional technologies, the door lock catch screw connection plate of this design can slide within a certain range while closely fitting the B-pillar. This improvement greatly enhances the assembly convenience of the door lock catch. At the same time, by carefully checking the fit between the lug and the B-pillar, it effectively prevents the loosening of the door lock catch caused by improper installation, ensuring the safety and stability during vehicle use.

[0023] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manner, structure, features and their effects of the present utility model as follows.
[0024] As Figure 3 -9 shows a slidable mounting structure of a door lock catch for an automobile cab, which includes a side panel 1, a B-pillar 2, a door lock catch screwing plate 3, a clamping piece 4, and a door lock catch 5. The B-pillar 2 is provided at the side panel 1. The clamping piece 4 is an elastic clamping piece. The fixing parts of the two clamping pieces 4 are fixed inside the B-pillar 2, on the upper and lower sides of the door lock catch screwing plate 3. The door lock catch screwing plate 3 is inside the B-pillar 2, and the invisible part is represented by a dotted line. The clamping parts of the two clamping pieces 4 fix the door lock catch screwing plate 3 to the B-pillar 2. Circular holes 31 are provided on the upper and lower sides of the door lock catch screwing plate 3, and a convex bump 41 is provided on the clamping part of the clamping piece 4. The convex bump 41 is located inside the circular hole 31. Through the cooperation of the convex bumps 41 on the two elastic clamping pieces 4 and the two circular holes 31 on the door lock catch screwing plate 3, the door lock catch screwing plate 3 can slide within a certain range to meet the adjustment needs during the assembly of the door lock catch 5 and the door lock 6 installed on the door 7. Moreover, under the elastic pressure of the two clamping pieces 4, the door lock catch screwing plate 3 is always in contact with the B-pillar 2. In addition, as Figure 7 shown, the door lock catch screwing plate 3 is provided with a lug 32, and the fitting condition of the door lock catch screwing plate 3 can be inspected from the notch 11 of the side panel 1. The above design ensures that the door lock catch 5 is easy to assemble and avoids the phenomenon of the door lock catch 5 being not installed in place.
[0025] Principle of use:
[0026] The clamping parts of the two clamping pieces clamp the door lock catch screwing plate and make the convex bumps of the clamping pieces correspond to the circular holes of the door lock catch screwing plate. Weld the fixing parts of the two clamping pieces to the B-pillar. During installation, adjust the position of the door lock catch screwing plate according to the adjustment needs during the assembly of the door lock catch and the door lock, and check the fitting condition of the door lock catch screwing plate and the B-pillar by looking at the lug through the notch of the side panel.
[0027] The above is only a preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to make equivalent embodiments of equivalent changes within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
