[0047] An opening and closing lock shifting plate 6 has one end connected to the actuator via a rocker arm 2. The output of the actuator drives the rocker arm to swing, thereby driving the opening and closing lock shifting plate to move. The opening and closing lock shifting plate is connected to the closing and unlocking shift column and can control the movement of the closing and unlocking shift column. The opening and closing lock shifting plate 6 is also connected to an internal locking pull wire 1003 for manually controlling the swing of the opening and closing lock shifting plate. The actuator electrically controls the swing of the opening and closing lock shifting plate, thereby realizing both electric and manual modes.

[0048] The closing and unlocking gear column is in two states when under electric or manual action. State one: in the unlocking state, it drives the upper and lower lock opening connecting plates and the inner and outer opening connecting plates to run synchronously to realize the opening of the upper lock body assembly and the lower lock body assembly; State two: when in the insurance state, the upper and lower lock opening connecting plates are provided with an avoidance structure, which can allow the closing and unlocking gear column to move in the avoidance structure when the outer handle or the inner handle is pulled.

Its working method is the prior art and is not described in detail.

[0050] Among them, the actuator 1 is installed on the mounting bracket 9, and the opening and closing lock displacement plate 6 is provided with a mounting column 64, the lower end of the mounting column 64 is installed on the mounting bracket, and a plurality of claws 640 are processed on the end surface of the mounting column 64. The opening and closing lock displacement plate 6 is centered on the mounting column 64, and the opening and closing lock displacement plate 6 is bent into a docking step, and the docking step is connected to the swing rod connecting column 62 connected to the swing rod. The actuator is connected to the swing rod 2, and the actuator drives the swing rod 2 to swing through the rotation of the output end. It should be pointed out that the actuator is electrically actuated, and the output end can rotate. There are a lot of existing technical supports that will not be explained. This scheme uses the rotation of the actuator to drive the swing rod to move, and then drives the opening and closing lock displacement plate 6 connected to the swing rod to achieve the purpose of electrically applying or releasing the insurance. The avoidance structure is mainly composed of the following: the inner and outer opening connecting plate 3 (reference Figure 8 ) is provided with a locking slot 31 and an escape slot 32, the escape slot 32 is communicated with the locking slot 31, wherein the escape slot 32 is an arc-shaped hole, the upper and lower lock opening connecting plate 4 is provided with a slot 41, the opening and closing lock displacement plate 6 (reference Figure 6 ) is provided with a connecting slot 61, and a closing and unlocking gear column 5 is installed on the slot 41. Under the action of external force, the closing and unlocking gear column can move along the slot 41, and the closing and unlocking gear column has a lower column 54 facing and extending into the connecting slot and an upper column 53 facing and extending into the locking slot. When the upper column 53 of the closing and unlocking gear column is located in the locking slot 31 and is in a contact insurance state (that is, the unlocking state can be achieved), the inside and outside opening connecting plate 3 and the upper and lower locking and opening connecting plate 4 operate synchronously.

[0051] The inner and outer opening connection plate is provided with an outer opening connection position 34 and an inner opening connection position 33. The outer opening connection position 34 is reserved for connecting the outer opening pull rod, which can be connected to the outer handle and can push the inner and outer opening connection plate to rotate counterclockwise when opening. The inner opening connection position 33 is reserved for connecting the inner opening pull wire 1004, and the other end of the pull wire is connected to the inner handle.

[0052] The upper and lower lock opening connecting plates are provided with an upper lock connecting position 42 and a lower lock connecting position 43. The reserved upper lock connecting position 42 is used to connect the upper lock body assembly, and the reserved lower lock connecting position 43 is used to install the lower lock body assembly. The upper lock body assembly and the lower lock body assembly are both door lock structures, and the lock bodies of automobile door locks on the market can be applicable without detailed description.

[0053] The closing and unlocking gear column has an upper limit ring 51 and a lower limit ring 52, both of which are larger than the width of the slot, and a mounting portion for adapting to the slot is formed between the upper limit ring and the lower limit ring. The mounting structure of the closing and unlocking gear column is designed to be installed on the upper and lower lock and open connecting plates, and the closing and unlocking gear column has a lower column 54 and an upper column 53. The end of the lower column 54 faces and extends into the connecting slot, and the end of the upper column 53 faces and extends into the locking slot, so as to achieve the control function.

[0054] The technology of this scheme is further explained: the closing and unlocking gear column connects the inside and outside opening connecting plate and the upper and lower lock opening connecting plates: 1. When the insurance is released (the upper column of the closing and unlocking gear column is in the locking slot 31), the upper and lower lock opening connecting plates 4 and the inside and outside opening connecting plates 3 rotate counterclockwise at the same time, and the upper and lower locks are opened at the same time; 2. When the insurance is on (the upper column of the closing and unlocking gear column is in the avoidance slot 32), when the inside and outside opening connecting plates 3 rotate counterclockwise, the avoidance slots thereon avoid the closing and unlocking gear column, the upper and lower lock opening connecting plates 3 do not move, and the upper and lower locks are not opened.

[0055] The structure of an upper lock body assembly is described as follows: it includes an upper lock body 101, the upper lock body 101 includes an upper lock body shell 105, a lock leaf 106 and a stop hook 104, the upper lock body shell has a lock port 107, the lock leaf 106 is installed on the upper lock body shell through a lock leaf shaft 1062 and opens or closes the lock port 107, the stop hook 104 is installed on the upper lock body shell through a stop hook shaft 108, the stop hook cooperates with the lock leaf, and the stop hook and the lock leaf cooperate to work The formula is the prior art and will not be described in detail. The upper lock body shell is provided with an elastic sheet 113, one end of which is formed on the upper lock body shell, and a lower gap A is formed between the elastic sheet and the bottom wall of the upper lock body shell, and a side activity space 115 is formed between the elastic sheet and the side wall of the upper lock body shell. The lateral distance of the side activity space 115 is greater than the height of the lower gap A. This method allows the elastic sheet to have enough space to deform. The purpose of the lower gap A is to allow the elastic sheet to be in a free state, so that the elastic sheet can swing and achieve reset. The side of the elastic sheet 113 is placed along the direction of the lock mouth, that is, it is designed along the depth direction of the lock mouth. The main purpose is that the lock bolt 102 also enters from the outer end of the lock mouth during movement, and will contact the side wall of the elastic sheet during the process. This solution changes the previous fixed side of the lock mouth into a deformable side wall. The structure has strong applicability and lower assembly requirements than before. The use of the deformable elastic sheet can reduce the problem of unevenness caused by errors, and at the same time solve the current hard contact and excessive collision sound.

[0056] A buffer block 114 is arranged in the side movable space between the elastic sheet and the side wall of the upper lock body shell. The buffer block 114 has an upper lock body shell contact surface facing the side wall of the upper lock body shell and an elastic sheet contact surface facing the outer wall of the elastic sheet. By utilizing multiple surface contacts, there will not be an excessive gap between the buffer block 114 to prevent the generation of shaking noise. The design of the buffer block facilitates to increase the service life of the elastic sheet and further reduce noise.

[0057] A limiting side wall 116 for limiting the movement of the buffer block is processed on the side wall of the upper lock body shell. The limiting side wall is arranged in the side activity space to further limit the movable space of the buffer block and improve stability.

[0058] The upper lock body shell is processed with a stop hook limiting column 112, and the stop hook limiting column is covered with a stop hook limiting column buffer sleeve 110. The upper lock body shell is processed with a lock leaf limiting column 111, and the lock leaf limiting column is covered with a lock leaf limiting column buffer sleeve 109. The stop hook limiting column buffer sleeve 110 and the lock leaf limiting column buffer sleeve 109 of this solution are used to reduce the noise generated when the stop hook and the lock leaf are working.

[0059] In order to further improve the mute effect, the locking leaf 106 and the stop hook 104 are both covered with a plastic coating layer, and the plastic coating layer is divided into a stop hook plastic coating layer 1041 and a locking leaf plastic coating layer 1041 .

[0060] The upper lock body shell is also processed with an integrally formed mounting epitaxial sheet 117, and the mounting epitaxial sheet is movably connected with a pull tab 103 through a pin shaft 1033. The pull tab 103 has a pull tab connecting end 1034 and a starting end sheet 1031 for driving the stop hook to move, wherein the pull tab connecting end 1034 is used to connect the pull wire 100 or the pull rod, and the pull tab connecting end 1034 is pulled by the pull wire 100 or the pull rod, and the pin shaft 1033 is used as the rotation center to drive the starting end sheet 1031 to move, thereby driving the stop hook above the starting end sheet 1031 to move, so as to open the contact with the lock leaf and realize unlocking.

[0061] The mounting bracket 9 is provided with an upper locking connection wire anti-detachment structure and a lower locking connection wire anti-detachment structure. The upper locking wires 1007 are connected to the upper locking connection position through the upper locking connection wire anti-detachment structure, and the lower locking wires are connected to the lower locking connection position through the lower locking connection wire anti-detachment structure.

[0062] Both the upper locking connection pull wire anti-slip structure and the lower locking connection pull wire anti-slip structure include an anti-slip seat 1012 and an anti-slip clamping plate 1009. An inner recess 1013 is provided at one end of the anti-slip seat 1012, and a buckle outer step is provided at the other end. A pull wire storage cavity 1008 is provided in the middle of the anti-slip seat 1012. The anti-slip clamping plate 1009 has an anti-slip clamping plate shaft 1011, which is installed on the inner recess 1013. The other end of the anti-slip clamping plate 1009 has a claw 1010, which is clamped on the buckle outer step with the anti-slip clamping plate shaft 1011 as the rotation center to prevent it from being stuck in the pull wire storage cavity 1008 and moving, thereby ensuring the reliability of the connection and preventing the pull wire from being unstable during installation or use.

[0063] It should be pointed out that the lower lock body assembly can adopt the structure of the upper lock body assembly, that is, it can adopt the same structure, or it can be a lock body structure on the market.

[0064] The present invention can meet the demand for a B-pillar-free door lock system and can basically solve the complex structure of the current entire system. Through the simplified design of the present solution, the same effect can be achieved with relatively high reliability, which is conducive to market promotion and use.
