Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to automotive tailgate lock latches. Background Technology

[0002] Enclosed logistics vehicles typically use a double-door rear door system for convenient loading, unloading, and cargo handling. The locks and latches are installed on separate sides of each door. Frequent opening and closing of the double doors, or the tendency for relative movement between the left and right doors during cargo transport, subject the locks and latches to frequent stress, causing deformation. Significant deformation makes opening and closing the doors difficult; in severe cases, the mounting points may crack or break, impacting customer experience. Therefore, the mounting points for the double-door rear door latches need to be sufficiently large to resist deformation from external forces and ensure operational requirements are met.

[0003] For example, CN214659496U, published on November 9, 2021, discloses a tailgate latch for automobiles, including a base plate. Buffer blocks are fitted on both sides of the base plate, and patches are provided on the inner side of the buffer blocks. A rod is fixedly installed on one side of the top of the patch, and a hammer-shaped rod is fixedly installed on one side of the bottom of the patch. A locking pin is snapped into the top of the base plate, and screw holes are provided on both sides of the locking pin. An installation mechanism is provided on one side of the locking pin. After long-term use, the latch disclosed above is prone to shaking, making it unable to connect properly and resulting in poor practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a stable car tailgate latch. This invention achieves stable installation of the latch by using a latch reinforcement plate and a reinforcement seat located on the inner panel of the double-leaf door, thereby preventing the latch from shaking after installation and improving its practicality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a car tailgate latch, including an inner panel and an outer panel of a double-opening door connected to each other. The inner panel of the double-opening door is provided with a latch, a latch reinforcement plate is provided on the inner panel of the double-opening door, a reinforcement seat is provided on the latch reinforcement plate, and a nut plate is provided on the latch reinforcement plate. The nut plate is connected to the latch by bolts.

[0006] The locking reinforcement plate is provided with a pin mounting box, and the nut plate is snapped into the pin mounting box.

[0007] The inner panel of the double door and the locking reinforcement plate are provided with through holes for bolts to pass through, and the nut plate is provided with threaded holes that mate with bolts.

[0008] The cross-section of the locking reinforcement plate is L-shaped, and the cross-sections of the reinforcement seat and the locking reinforcement plate are triangular.

[0009] The reinforcing seat is provided with reinforcing protrusions and a contact surface that abuts against the locking reinforcing plate.

[0010] The pin mounting box is welded to the buckle reinforcement plate, the buckle reinforcement plate is welded to the reinforcement seat, and the buckle reinforcement plate is welded to the inner panel of the double door.

[0011] The beneficial effects of this utility model are:

[0012] The rigidity of the rear door latch mounting point is increased by setting a latch reinforcement plate and a reinforcement seat, thereby preventing the latch from shaking and making it more practical.

[0013] The cross-section of the locking reinforcement plate is L-shaped, and the cross-sections of the reinforcement seat and the locking reinforcement plate are triangular, thereby increasing the strength of the locking reinforcement plate and the mounting seat, and further increasing the strength of the lock installed on the locking reinforcement plate;

[0014] The reinforcing seat has reinforcing protrusions to increase its strength. The reinforcing seat also has a contact surface that abuts against the locking reinforcing plate, thereby increasing the contact area between the reinforcing seat and the locking reinforcing plate and thus increasing the strength of the connection between them.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figure 1-4As shown, the car tailgate latch includes an inner panel 1 and an outer panel 2 connected to each other. The inner panel 1 is provided with a latch 7, a latch reinforcement plate 4, a reinforcement seat 3, and a nut plate 6. The nut plate 6 is connected to the latch 7 by bolts. Specifically, the latch reinforcement plate 4 is located at the bend of the inner panel 1. In this embodiment, the latch 7 includes a mounting plate with two through holes for bolts to pass through and an annular plate.

[0023] In use, the locking reinforcement plate 4 and the reinforcement seat 3 are connected to the inner panel 1 of the double door, the nut plate 6 is connected to the locking reinforcement 4, and the bolts are passed through the locking 7 and the inner panel 1 of the double door and connected to the nut plate 6, thereby achieving a stable connection of the locking 7 on the inner panel 1 of the double door. The setting of the locking reinforcement plate 4 and the reinforcement seat 3 increases the rigidity of the locking point of the rear door lock, thereby preventing the locking 7 from shaking and making it more practical.

[0024] The locking reinforcement plate 4 is provided with a pin mounting box 5. The nut plate 6 is snapped into the pin mounting box 5. The connection between the nut plate 6 and the locking reinforcement plate 4 is achieved through the pin mounting box 5. Specifically, the nut plate 6 is nested and connected to the pin mounting box 5.

[0025] The inner panel 1 of the double door and the locking reinforcement plate 4 are provided with through holes for bolts to pass through. The nut plate 6 is provided with threaded holes that mate with bolts. The bolts pass through the inner panel 1 of the double door, the locking reinforcement plate 4, the locking 7 and the nut plate 6 to connect, thereby realizing the installation of the locking 7. Specifically, the nut plate 6 is long and has two threaded holes that mate with bolts.

[0026] The cross-section of the locking reinforcement plate 4 is L-shaped, and the cross-sections of the reinforcement seat 3 and the locking reinforcement plate 4 are triangular, thereby increasing the strength of the locking reinforcement plate 4 and the mounting seat 3, and further increasing the strength of the lock 7 installed on the locking reinforcement plate 4.

[0027] The reinforcing seat 3 is provided with a reinforcing protrusion 301, thereby increasing the strength of the reinforcing seat 3. The reinforcing seat 3 is provided with a contact surface 302 that abuts against the locking reinforcing plate 4, thereby increasing the contact area between the reinforcing seat 3 and the locking reinforcing plate 4, thereby increasing the strength after the reinforcing seat 3 and the locking reinforcing plate 4 are connected.

[0028] The pin mounting box 5 is welded to the latch reinforcement plate 4, the latch reinforcement plate 4 is welded to the reinforcement seat 3, and the latch reinforcement plate 4 is welded to the inner panel 1 of the double door, thereby achieving a stable connection between the reinforcement seat 3, the pin mounting box 5, and the latch reinforcement plate 4.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
