Fig. 3(a), Fig. 3(b), Fig. 3(c), Fig. 3(d) and Fig. 3(e) are schematic diagrams of a series of installation operations of the embodiment shown in the present invention.

Detailed ways

The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

An integrated car door lock, including at least one set of lock motor 1, lock body 2, lock motor connecting bracket and angle conversion mechanism, the lock motor connecting bracket is L-shaped, including a lock motor mounting plate 4 and a lock body mounting plate connected to it 5. The lock body 2 is installed vertically on the lock body mounting plate, the lock motor 1 is installed on the lock motor mounting plate 4, and the lock body 2 and the lock motor 1 are connected through an angle conversion mechanism.

The structure is designed according to the actual design of the installation position of the door lock, and the general principle and structure are similar. When the lock motor 1 is installed on the lock motor mounting plate 2, the boundary between the lock motor 1 and the lock motor mounting plate 2 needs to maintain a certain size gap. The specific size is designed according to the actual needs to meet the assembly requirements and ensure convenient installation. The lock motor is connected to the bracket To ensure the movement strength of the lock motor 1, the lock motor 1 ensures the angle at which the lock motor 1 drives the lock body 2 through an angle conversion mechanism, so as to reduce the volume of the entire lock device by a certain amount.

In this embodiment, the connecting bracket of the lock motor 1 is an L-shaped bracket, and the corner radian of the L-shaped bracket needs to be determined according to actual CAE analysis to meet the strength requirements and assembly requirements of the integrated door lock.

In this embodiment, the angle conversion mechanism is the driving link 3 . The driving connecting rod 3 is stamped and formed, and the driving connecting rod 3 functions as the connection between the lock motor 1 and the lock body 2. There are many connection methods. connected.

In this embodiment, the lock motor 1 connecting bracket is also provided with reinforcing ribs 8 to strengthen the strength of the lock motor connecting bracket to prevent problems such as breakage of the lock motor connecting bracket during use or installation, so as to reduce the failure rate of the product .

The lock motor connection bracket is respectively provided with a positioning via hole 6 and a plurality of connection via holes 7, and the positioning via hole 6 is located at the junction of the lock motor mounting plate 4 and the lock body mounting plate 5, so that in the actual production and installation process, as a small For the positioning of the assembly, the connection via hole 7 is used to fix the lock motor 1. In this embodiment, the positioning via hole 6 and the connection via hole 7 are both bolt via holes.

In this embodiment, the lock body 2 is connected to the lock body mounting plate 5 through riveting, bolting or welding.

The integrated lock device shown in the present invention is also very convenient to install, the installation process is simple, and the error rate is extremely low in the mass production process. The installation process is shown in Figure 3, and it is specifically divided into the following steps:

As shown in Figure 3(a), first, pull out the lock motor 1 wire socket from the door lock hole, and connect the lock motor 1 with the wire; as shown in Figure 3(b), install one end of the lock motor 1 through the lock hole; as shown in Figure 3(c) and Figure 3(d), continue to push the lock mechanism along the corner of the lock mechanism until the lock installation surface is aligned with the door lock installation hole surface; as shown in Figure 3(e) As shown, when the integrated car lock is installed in place, use the positioning bolt to position it at this time, and tighten the fixing bolt to complete the installation process of the car lock.

Through the above steps, the installation of the lock can be successfully completed. This lock can increase the function of the lock device by increasing the motor function and the number of motors, thereby enriching the configuration of the door lock hole position and reducing unnecessary waste of space.

The above description of the embodiments is for those of ordinary skill in the art to understand and apply the present invention. It is obvious that those skilled in the art can easily make various modifications to these embodiments, and apply the general principles described here to other embodiments without creative effort.
