Fig. 1 and 2 show reference direction coordinate systems of embodiments of the present invention, and the embodiments of the present invention will be described below with reference to the directions shown in fig. 1 and 2.

Referring to fig. 1, 2 and 3, an embodiment of the present invention provides a mechanical lock body structure, which includes a lock body frame 1, a first lock catch assembly 2 and a second lock catch member 3, wherein the lock body frame 1 is provided with a lock hole 11.

The first locking assembly 2 comprises a first locking part 21 and an elastic part 22, the first locking part 21 is provided with a rotating shaft 211, the lock body framework 1 is provided with a shaft hole, the first locking part 21 is rotatably arranged on the lock body framework 1 through the rotating shaft 211, and the first locking part 21 can rotate around the rotating shaft 211 within a certain angle range to realize locking and unlocking actions. The first locking member 21 is provided with a first hook 212 in front of the rotating shaft 211, the first locking member 21 extends backward along the locking hole 11, the first locking member 21 is provided with an installation seat 213 behind the rotating shaft 211, a gap is left between the first hook 212 and the installation seat 213, the elastic member 22 is arranged in the locking hole 11, one end of the elastic member 22 is connected with the installation seat 213, and the other end extends forward along the locking hole 11.

The second locking part 3 is connected with an external part to be locked, and the second locking part 3 is provided with a second hook 31.

The second locking member 3 is inserted into the locking hole 11 and compresses the elastic member 22, and the elastic member 22 pushes the first locking member 21 to rotate around the rotating shaft 211, so that the first hook 212 is engaged with the second hook 31.

With reference to fig. 1, the locking process: the second locking member 3 is pressed down into the locking hole 11, compressing the resilient member 22. Due to the action of the elastic component 22, the first locking component 21 rotates (clockwise) around the rotating shaft 211 on the lock body framework 1, and after the second locking component 3 is inserted into the lock hole 11 for a certain depth, the second locking component 3 is finally locked with the first locking component 21, so that the locking function is realized.

Unlocking and bouncing: the first locking member 21 is rotated (counterclockwise) around the rotation shaft 211 of the lock body frame 1, so that the first hook 212 of the first locking member 21 is separated from the second hook 31 of the second locking member 3, thereby unlocking. In addition, after the first locking member 21 rotates, the rear end pushes the elastic member 22, and the elastic member 22 further pushes the second locking member 3, so as to realize the bouncing function.

According to the embodiment of the invention, the lock body structure and the bouncing function are integrated, so that not only can the basic locking function be realized, but also the second lock catch part 3 can be bounced outwards after unlocking, and the opening and closing locking of parts such as the oil filling cover, the charging opening cover and the interior trim storage box cover are facilitated. The elastic part 22 is used for realizing linkage between the first locking part 21 and the second locking part 3 in the locking and unlocking processes, the structure is simple, and the reliability of the lock body is improved. The space is small and exquisite, has saved the space for the design of periphery. The parts constitute fewly, save the cost.

In order to make the second locking member 3 better receive the acting force from the elastic member 22 during the locking and unlocking processes, in some embodiments, referring to fig. 3, the first locking assembly 2 further includes a slider 23, the slider 23 is disposed in the locking hole 11 and can slide back and forth along the locking hole 11, one end of the elastic member 22 is connected with the mounting seat 213, and the other end is connected with the slider 23. The acting force of the elastic component 22 acts on the second locking component 3 through the sliding block 23, so that the acting force of the elastic component 22 acts on the second locking component 3 along the sliding direction of the sliding block 23, and the locking and unlocking processes of the second locking component 3 are smoother.

Further, referring to fig. 3, the lock body frame 1 is provided with slider guide grooves 12 on left and right sides of the lock hole 11, the slider guide grooves 12 extend in the front-rear direction and form an opening at a rear end of the lock body frame 1, and the outer surfaces of left and right sides of the slider 23 are provided with limit ribs 231 engaged with the slider guide grooves 12. The limiting rib 231 is matched with the slider guide groove 12 to realize the guiding of the slider 23, and the first locking part 21 which is rotated is prevented from being inclined and deviating from the sliding direction in the lock hole 11.

The elastic member 22 is used to push the first locking member 21 to rotate around the rotating shaft 211 to engage with the second locking member 3 during the locking process, and to push the second locking member 3 to pop out of the locking hole 11 during the unlocking process. The elastic member 22 may take various structural forms as required, for example, in some embodiments, the elastic member 22 includes a compression spring, the sliding block 23 and the mounting seat 213 are both provided with spring pins 232 and 214 connected with the compression spring, and both ends of the elastic member 22 are sleeved on the spring pins to achieve a stable connection.

In some embodiments, referring to fig. 1 and 2, the end of the first locking member 21 and/or the second locking member 3 is provided with a guiding inclined surface 215 to push the first locking member 21 away before the second locking member 3 is inserted into the locking hole 11.

Referring to fig. 2, in order to restrict the swing angle of the first locking member 21 within a certain range, the lock body frame 1 is provided with a limit stop 13 for limiting the rotation angle of the first locking member 21, and the limit stop 13 is disposed at a position to ensure that the two locking members can be smoothly inserted into or withdrawn from the locking hole 11.

In some embodiments, the distance between the first hook 212 and the rotating shaft 211 is greater than the distance between the mounting seat 213 and the rotating shaft 211, so as to ensure that the rotating arm of the first hook 212 is greater than the rotating arm at the position of the mounting seat 213.

The first latch member 21 may be actuated by providing a button, knob, motor or cylinder to effect the unlocking action, for example, in some embodiments, referring to fig. 1-3, the first latch member 21 has an unlocking force applying arm 216, the unlocking force applying arm 216 is formed as a unitary structure with the first latch member 21, and the unlocking force applying arm 216 is connected to the drive cable 4. When the unlocking is needed, the driving cable 4 is pulled, the driving cable 4 drives the unlocking force applying arm 216, and the unlocking force applying arm 216 drives the first locking component 21 to rotate anticlockwise around the rotating shaft 211, so that the unlocking action is realized. This embodiment can realize remote unblock action through adopting drive cable 4, and the structure is simpler, reliable.

Further, in order to reduce the traction force required by unlocking, the end of the unlocking force application arm 216 is provided with a cable installation hole 217, the driving cable 4 is connected to the cable installation hole 217, and the distance between the cable installation hole and the rotating shaft 211 is greater than the distance between the installation seat 213 and the rotating shaft 211.

The embodiment of the invention also provides an automobile which comprises the mechanical lock body structure in any one of the embodiments. For example, the locking device can be used for a fuel filler cap, an armrest box cover, a charging port cover and the like to realize unlocking and bouncing functions.
