[0018] To make the technical content, structural features and effects of the utility model clear, the following will be described in detail in combination with the embodiments and the drawings.

[0019] As shown in Figures 1 to 3 the utility model discloses a car door latch with universal switch 100, which comprises a latch device 1 and a switch mechanism 2. The latch device 1 comprises a seat body 11 and a locking piece 12. The locking piece 12 is pivotally connected to the seat body 11 through a rotating shaft 123 and controls the locking or unlocking of the latch device 1. The switch mechanism 2 comprises a connector 21 and an elastic reset piece 22. The seat body 11 is provided with a mounting hole 11a. One end of the locking piece 12 is provided with a trigger part 121. One end of the connector 21 is provided with a connecting handle 211. The other end of the connector 21 is provided with a spherical surface 212. The spherical surface 212 is installed in the mounting hole 11a. The trigger part 121 abuts against the upper side of the spherical surface 212. When the connector 21 is shaken in any direction, the connector 21 is lifted and pushes the trigger part 121 under the abutment of the spherical surface 212 and the mounting hole 11a, so that the trigger part 121 drives the locking piece 12 to rotate, thereby unlocking the latch device 1. The elastic reset piece 22 is arranged between the seat body 11 and the connector 21 to provide an elastic force for resetting the spherical surface 212. The elastic reset piece 22 is a compression spring.

[0020] Please also refer to Figures 1 to 3The locking device 1 further includes a locking hook 13, a first elastic element 14, and a second elastic element 15. One side of the base 11 has a first opening 11b, one end of the locking hook 13 has a second opening 13a, and the other end opposite to the second opening 13a has a locking portion 13b. The locking hook 13 is pivotally connected to the base 11 via a pivot 131, so that when rotated to one side, the second opening 13a at least partially overlaps with the outlet of the first opening 11b, or when rotated to the other side, the second opening 13a... The outlets of the first opening 11b are offset; the first elastic member 14 is disposed between the seat 11 and the locking hook 13 to provide an elastic force that offsets the second opening 13a from the first opening 11b; the locking member 12 has an engaging recess 122 on the side near the engaging portion 13b, the engaging recess 122 engaging or disengaging with the engaging portion 13b; the engaging portion 12b has a toothed structure or a stepped structure, and the engaging recess 122 has a toothed structure or a stepped structure that mates with the engaging portion 12b. The second elastic member 15 is disposed between the seat 11 and the locking member 12 to provide an elastic force that brings the engaging recess 122 closer to the engaging portion 13b. Both the first elastic member 14 and the second elastic member 15 are torsion springs. By opening a first opening 11b in the seat 11 and a second opening 13a in the locking hook 13, and by pivoting the locking hook 13 onto the seat 11, the second opening 13a can at least partially overlap or completely offset from the outlet of the first opening 11b when the locking hook 13 rotates, thereby allowing the shaft 200 to enter the first opening 11b and be locked by the locking hook 13. Furthermore, by providing a locking portion 13b at the other end of the locking hook 13, and by pivotally connecting the locking member 12 to the base 11, and providing a locking recess 122 on the locking member 12, the locking portion 13b can be locked using the locking recess 122, thereby preventing the locking hook 13 from rotating. The locking member 12 only needs the elastic force provided by the second elastic member 15 to achieve the locking purpose. Therefore, during operation, the user only needs to apply a small force to overcome the elastic force of the second elastic member 15, and then use the elastic force of the first elastic member 14 to drive the locking hook 13 to rotate, thereby releasing the shaft 200 in the first opening 11b. It has high strength, is very simple to operate, saves time and effort, and is very convenient to use.

[0021] For example Figure 3 As shown, one end of the base 11 is bent to form a support portion 111, and the switching mechanism 2 is mounted on the support portion 111. The support portion 111 makes it easier and more convenient to mount the switching mechanism 2 onto the base 11.

[0022] For example Figure 3As shown, the side wall of the joint 21 is provided with a through hole 21a in the radial direction. The outer end of the joint 21 is axially provided with a connecting hole 21b which is communicated with the through hole 21a, and the connecting hole 21b is provided with a screw 21c which extends into the through hole 21a. By providing the through hole 21a, the joint 21 can be connected with a flexible member, so that the joint 21 is driven to move by the flexible member, thereby facilitating the operation.

[0023] As shown in FIG. 4, Figure 1 and Figure 3 As shown, the upper side of the spherical surface 212 is provided with a limiting ring 213, and when the spherical surface 212 is sleeved in the mounting hole 11a, the limiting ring 213 abuts against the surface of the mounting hole 11a of the seat body 11. The limiting ring 213 can not only limit the spherical surface 212 to prevent the spherical surface 212 from being separated from the mounting hole 11a, but also abut against the trigger part 121 to drive the locking member 12 to rotate.

[0024] As shown in FIG. 4, Figure 1 and Figure 3 As shown, the upper side of the spherical surface 212 is recessed to be provided with a containing groove 214, and one end of the elastic reset member 22 is contained in the containing groove 214. In this way, the elastic reset member 22 and the spherical surface 212 can be stably contacted, and the stability of the operation of the joint 21 is ensured. The elastic reset member 22 is a compression spring.

[0025] In combination with the above and the accompanying drawings, Figure 2 and Figure 4 The working principle of the car door impact lock 100 with the universal switch of the utility model will be described in detail as follows.

[0026] When it is needed to lock the shaft body 200 on the seat body 11, only need to put the shaft body 200 directly into the first opening 11b, the shaft body 200 enters the second opening 13a at the same time of entering the first opening 11b, at this time the shaft body 200 pushes the lock hook 13, so that the lock hook 13 rotates. When the shaft body 200 is completely entered into the first opening 11b, the outlet of the second opening 13a of the lock hook 13 is just staggered with the outlet of the first opening 11b, and then the shaft body 200 is completely locked in the first opening 11b, and the locking is realized. At the same time, the clamping part 13b of the other end of the lock hook 13 is just clamped in the clamping recess 122 of the locking piece 12, and the both are kept in the locked state under the elastic force of the second elastic piece 15. When it is needed to unlock the shaft body 200, the connecting handle 211 of the flexible piece or the joint 21 is directly swung to any direction, so that the joint 21 as a whole swings, at this time the upper end of the joint 21 is lifted under the cooperation of the spherical surface 212 and the mounting hole 11a. The upper side of the limiting ring 213 pushes the trigger part 121 against the elastic force of the elastic reset piece 22, so that the trigger part 121 drives the locking piece 12 to rotate, and the locking piece 12 rotates. At this time the clamping recess 122 of the locking piece 12 is away from the lock hook 13, so that the clamping recess 122 is separated from the clamping part 13b. The lock hook 13 rotates around the rotating shaft under the elastic force of the first elastic piece 14, so that the outlet of the second opening 13a is turned, and then at least partially overlaps with the outlet of the first opening 11b. At this time the shaft body 200 clamped in the first opening 11b can be separated from the seat body 11, and the unlocking is realized.

[0027] Compared with the prior art, since the mounting hole 11a is arranged on the seat body 11, the spherical surface 212 is arranged on the joint 21, and the spherical surface 212 is arranged in the mounting hole 11a, and the arc surface of the outer periphery of the spherical surface 212 is utilized, so that when the joint 21 is swung to any direction, the joint 21 can be lifted by the cooperation of the spherical surface 212 and the mounting hole 11a, and then the trigger part 121 arranged above is pushed, so that the trigger part 121 drives the locking piece 12 to rotate, and the purpose of unlocking the latch device 1 is achieved. Therefore, the scheme can be operated to unlock from any direction, the operation is simple, and the use is very convenient.

[0028] The above disclosed is only a preferred embodiment of the utility model, and of course cannot limit the right scope of the utility model, therefore the equivalent changes made according to the patent application scope of the utility model still belong to the range covered by the utility model.
