Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive door lock technology, and in particular to a door lock opening and closing system. Background Technology
[0002] Currently, in the automotive industry, pillarless cars are increasingly favored by the market due to their ease of passenger entry and exit and cargo loading and unloading. However, in practice, the opening methods of the front and rear doors in pillarless designs are mostly sequential, meaning the doors must open in a specific order, and this order cannot be changed once finalized. This makes it impossible to open the doors immediately in an emergency, hindering escape. Furthermore, currently used electric doors cannot be manually opened in emergencies, posing a safety threat. For example, patent 2023221015247 discloses a door lock system and vehicle. By placing the lock body on the upper and lower beams of the vehicle body and correspondingly placing the latches on the upper and lower parts of the door body, it allows for easy placement and installation of door locks on pillarless vehicles while ensuring reliable door locking. However, it still cannot solve the problem of the sequential opening of the front and rear doors, and the inability to change the opening order once finalized, thus preventing immediate door opening in an emergency. Therefore, solving the problem of the inconvenience caused by the need to pre-set the front and rear doors for opening pillarless car door locks in special circumstances is particularly important.

[0019] Manual system operating principle:
[0020] Locking action
[0021] When the front door is closed: a full lock signal of the rear door main lock is detected → the first actuator 4 turns in the locking direction → by pulling the middle lock closing cable 7 → the middle lock 2 is locked → the first actuator 4 reverses and resets.
[0022] The front door is closed: No full lock signal is detected for the rear door main lock → the middle lock 2 unlocks → the rear door can open or close.
[0023] The front door is in the open state: close the door to the fully locked position → detect the full lock signal of lock 1 / lock 3 / rear door main lock → the first actuator rotates forward → by pulling the middle lock closing cable 7 → the middle lock 2 is locked → the first actuator 4 reverses and resets.
[0024] The front door is in the open state: close the door to the fully locked position → no fully locked signal is detected for the rear door main lock → the middle lock 2 needs to perform the unlocking action → the rear door can perform the opening or closing action.
[0025] Unlocking action
[0026] When the front door is closed: Upon detecting an opening signal, the central lock 2 will automatically unlock, allowing the rear door to open or close.
[0027] When the front door is open: check if the central lock 2 is unlocked → if it is not unlocked, the central lock 2 will unlock itself → the rear door can open or close.
[0028] In case of power failure or manual operation:
[0029] With the front door closed: Pulling the mechanical inward / outward opening mechanism → unlocking the central lock 2 and triggering the central lock release extension cable 11 → the central lock release extension cable 11 pulls the upper lock release cable 5 and the lower lock release cable 8 through the one-to-two junction box 10 → unlocking the upper lock 1 and the lower lock 3 → the front door is fully unlocked → the rear door can perform opening or closing actions.

[0031] Operating principle of electric system:
[0032] Electric locking action
[0033] When the front door is closed: a lock signal is detected for lock 1 / lock 2 / rear door main lock → the first actuator 4 rotates forward → the middle lock 2 is locked by pulling the middle lock closing cable 7 → the first actuator 4 is reversed to reset.
[0034] The front door is closed: No full lock signal is detected for the rear door main lock → the middle lock 2 unlocks → the rear door can open or close.
[0035] The front door is in the open state: close the door to the half-lock position → the second actuator 12 rotates forward → by pulling the lower lock closing cable 13 → the lower lock 3 and upper lock 1 are locked → the upper lock 1 / lower lock 2 / rear door main lock full lock signal is detected → the second actuator 12 reverses to reset / the first actuator 4 rotates forward → the first actuator 4 rotates forward and pulls the middle lock closing cable 7 → the middle lock 2 is locked → the first actuator 4 reverses to reset.
[0036] When the front door is open: close the door to the half-lock position → the second actuator 12 rotates forward → by pulling the lower lock closing cable 13 → the lower lock 3 and upper lock 1 are locked → no full lock signal is detected for the rear door main lock → the second actuator 12 reverses to reset → the middle lock 2 needs to perform the unlocking action → the rear door can perform the opening or closing action.
[0037] Electric unlocking action
[0038] When the front door is closed: an opening signal is detected → the central lock 2 performs an unlocking action → at the same time, the first actuator 4 turns in the unlocking direction → driving the upper and lower lock electric release cables 15 to pull the upper lock release cable 5 and the lower lock release cable 8 through the two-to-two junction box 10' → enabling the upper lock 1 and the lower lock 3 to unlock → the front door is fully unlocked and the rear door can perform opening or closing actions.
[0039] When the front door is open: check if the central lock 2 is unlocked → if it is not unlocked, the central lock 2 will unlock itself → the rear door can open or close.
[0040] In case of power failure or manual operation:
[0041] When the front door is closed and locked, pulling the mechanical inward / outward opening mechanism unlocks the middle lock 2 and releases the middle lock extension cable 11. The middle lock release extension cable 11 pulls the upper lock release cable 5 and the lower lock release cable 8 through the two-to-two cable box 10', unlocking the upper lock 1 and the lower lock 3. The front door is now fully unlocked, and the rear door can open or close.
