Description

Technical Field

[0001] This application relates to the field of internal locking hand structure technology, and in particular to an internal locking hand linkage mechanism and vehicle. Background Technology

[0002] Inside the cockpit, occupants typically open the car door using the inside handle. Generally, when unlocking a framed door using the inside handle, simply pulling the cable to transmit a mechanical signal to the lock is sufficient to unlock it. However, for frameless doors, after unlocking, the door glass needs to be lowered slightly before the door can be opened to avoid damaging the glass.

[0003] When using a traditional mechanical inner latch to unlock the door, there is a certain delay in the mechanical transmission process. As a result, passengers may open the door before the glass has been lowered slightly, which can damage the door glass over time. Utility Model Content

[0004] Therefore, it is necessary to provide an internal latching linkage mechanism and vehicle to solve the problem that there is a certain delay in the mechanical transmission process, which makes it easy for drivers and passengers to open the car door before the door glass is slightly lowered.

[0005] The internal latch linkage mechanism provided in this application includes an actuator, a controller, a lifting motor, a handle, and a door lock. The actuator is electrically connected to the lifting motor through the controller. The lifting motor is used to drive the window to rise and fall, and the door lock is used to lock the vehicle door and body. When the door and body are closed, the handle can press against the actuator, putting the actuator in a closed state, and the door lock is in a locked state. When the handle is rotated along a preset direction by a first preset angle, the handle can disengage from the actuator, putting the actuator in an activated state, and the actuator can send a signal to the controller to control the window to lower by a predetermined height, and the door lock is in a locked state. When the handle is rotated along a preset direction by a second preset angle, the door lock is in an unlocked state, and the second preset angle is greater than the first preset angle.

[0006] In one embodiment, the internal latch linkage mechanism further includes a displacement sensor and an electronic safety latch. The electronic safety latch and the displacement sensor are electrically connected to the controller. The displacement sensor is installed on the window to detect the window's lifting height, and the electronic safety latch is used to cooperate with the door lock to lock the vehicle door and body. When the displacement sensor detects that the window has lowered less than a predetermined height, the displacement sensor can send a signal to the controller to cause the controller to control the electronic safety latch to be in a locked state. When the displacement sensor detects that the window has lowered more than or equal to the predetermined height, the displacement sensor can send a signal to the controller to cause the controller to control the electronic safety latch to be in an unlocked state.

[0007] In one embodiment, the starter includes a conductive spring and a conductive base. When the handle is pressed against the starter, the handle can push the conductive spring to elastically deform away from the conductive base, so that the starter is disconnected and in a closed state. When the handle and the starter are disengaged, the conductive spring can reset towards the conductive base and electrically connect to the conductive base, so that the starter is turned on and in a start state, and sends an electrical signal to the controller.

[0008] In one embodiment, the starter further includes a conductive contact, one end of which is connected to a conductive spring and the other end of which extends toward the handle. The handle can push the conductive contact to cause the conductive spring to elastically deform toward the direction away from the conductive base.

[0009] In one embodiment, the starter further includes a first magnetic element and a second magnetic element. The first magnetic element is mounted on the conductive spring and the second magnetic element is mounted on the conductive base. The first magnetic element and the second magnetic element can attract each other so that the conductive spring has a tendency to move toward the conductive base.

[0010] In one embodiment, the inner latch linkage mechanism further includes a mounting bracket, and both the starter and the handle are mounted on the mounting bracket. The handle is a lever structure, and the handle includes a rotating lever and a fulcrum. The rotating lever is rotatably connected to the mounting bracket through the fulcrum. When one end of the rotating lever rotates around the fulcrum, the other end of the rotating lever can be pressed and engaged with the starter.

[0011] In one embodiment, the inner latch linkage mechanism further includes a mounting bracket. The starter and the handle are both mounted on the mounting bracket. The handle is a rotating rod structure, which includes a rod body and a rotating shaft. The rotating shaft is located at one end of the rod body. The rod body is rotatably connected to the mounting bracket through the rotating shaft. The end of the rod body away from the rotating shaft is defined as the actuating end. When the actuating end rotates around the rotating shaft, the rod body located between the actuating end and the rotating shaft can press against the starter.

[0012] In one embodiment, the first preset angle M satisfies 1°≤M≤20°; and / or, the second preset angle N satisfies 10°≤N≤90°.

[0013] In one embodiment, the predetermined height H satisfies 3mm≤H≤10mm.

[0014] This application provides a vehicle that includes the internal latching linkage mechanism described in any of the above embodiments.

[0015] Compared with existing technologies, the internal latch linkage mechanism and vehicle provided in this application, as described above, ensure that when the handle is turned to open the car door, the actuator opens before the door lock. That is, the window lowers first, and then the door lock unlocks. In other words, the door lock will not open before the window is lowered. This design effectively ensures that occupants can only open the car door after the window has been slightly lowered, thus effectively preventing damage to the window. Attached Figure Description

[0021] Inside the cockpit, occupants typically open the car door using the inside handle. Generally, when unlocking a framed door using the inside handle, simply pulling the cable to transmit a mechanical signal to the lock is sufficient to unlock it. However, for frameless doors, after unlocking, the door glass needs to be lowered slightly before the door can be opened to avoid damaging the glass.

[0022] When using a traditional mechanical inner latch to unlock the door, there is a certain delay in the mechanical transmission process. As a result, passengers may open the door before the glass has been lowered slightly, which can damage the door glass over time.

[0023] Please see Figures 1-3To address the issue of delays in the mechanical transmission process, which can lead to passengers opening the car door before the window is fully lowered, this application provides an internal latch linkage mechanism and a vehicle. The internal latch linkage mechanism includes a mounting bracket 300, a starter 100, a controller (not shown), a lifting motor (not shown), a handle 200, and a door lock (not shown). The starter 100 is electrically connected to the lifting motor via the controller. The lifting motor is used to drive the window (not shown) to rise and fall. The door lock is used to lock the vehicle door (not shown) and the vehicle body (not shown). Both the starter 100 and the handle 200 are mounted on the mounting bracket 300.

[0024] When the car door and body are closed, the handle 200 can press against the starter 100, and the starter 100 is closed, and the door lock is locked.

[0025] When the handle 200 is rotated along the preset direction by a first preset angle, the handle 200 can disengage from the starter 100 and the starter 100 is put into the start state. The starter 100 can send a signal to the controller so that the controller controls the window to drop a predetermined height and the door lock is in the locked state.

[0026] When the handle 200 is rotated along the preset direction by a second preset angle, the door lock is in the unlocked state, wherein the second preset angle is greater than the first preset angle.

[0027] As can be seen from the above, when the handle 200 is turned to open the car door, the starter 100 opens before the door lock. That is, the window lowers first, and then the door lock unlocks. In other words, the door lock will not open before the window is lowered. This design effectively ensures that passengers can only open the car door after the window has been slightly lowered, thus effectively avoiding damage to the window.

[0028] In one embodiment, the predetermined height H satisfies 3mm≤H≤10mm, and preferably, H is 5mm.

[0029] With this setting, H≥3mm, it can be ensured that the window will not obstruct the opening of the door, and H≤10mm, it can prevent the window from falling too high, which would cause the falling time to be too long and affect the speed of the door opening.

[0030] In one embodiment, the first preset angle M satisfies 1°≤M≤20°, and preferably, M is 5°.

[0031] With this setting, M≥1°, the handle 200 can be prevented from turning due to vehicle body vibration, that is, the window can be prevented from falling down on its own when the vehicle body is vibrating. M≤20° can shorten the time interval between the starter 100 sending a signal to the control valve and improve the efficiency of opening the door.

[0032] In one embodiment, the second preset angle N satisfies 10°≤N≤90°, and preferably, N is 45°.

[0033] With this setting, N≥10° allows sufficient time for the window to lower, while N≤90° reduces the handle's rotation angle by 200°, improving the operational comfort for drivers and passengers.

[0034] In one embodiment, such as Figure 2 As shown, the starter 100 includes a conductive spring 110 and a conductive base 120. When the handle 200 is pressed against the starter 100, the handle 200 can push the conductive spring 110 to undergo elastic deformation in a direction away from the conductive base 120, so that the starter 100 is disconnected and in a closed state. When the handle 200 and the starter 100 are disengaged, the conductive spring 110 can be reset in a direction close to the conductive base 120 and electrically connected to the conductive base 120, so that the starter 100 is turned on and in a start state, and sends an electrical signal to the controller.

[0035] It should be noted that both the conductive spring 110 and the conductive base 120 are installed inside the housing 140 of the starter 100.

[0036] That is, by switching the starter 100's own circuit on and off, an electrical signal is sent to the controller to realize the raising and lowering control of the car window.

[0037] However, this is not the only one. In other embodiments, the starter 100 may be in the start state when the circuit is open and in the off state when the circuit is closed. Specifically, when the starter 100 is open, the controller may receive a signal that the starter 100 is disconnected.

[0038] Furthermore, in one embodiment, as Figure 2 As shown, the starter 100 also includes a conductive contact 130. One end of the conductive contact 130 is connected to the conductive spring 110, and the other end extends toward the handle 200. The handle 200 can push the conductive contact 130 to cause the conductive spring 110 to undergo elastic deformation toward the direction away from the conductive base 120.

[0039] This improves the efficiency of the cooperation between the handle 200 and the starter 100.

[0040] Furthermore, in one embodiment, as Figure 2 As shown, the starter 100 also includes a first magnetic 111 and a second magnetic 121. The first magnetic 111 is mounted on the conductive spring 110, and the second magnetic 121 is mounted on the conductive base 120. The first magnetic 111 and the second magnetic 121 attract each other so that the conductive spring 110 tends to move toward the conductive base 120.

[0041] This configuration can improve the electrical connection strength between the conductive spring 110 and the conductive seat 120, preventing the conductive spring 110 and the conductive seat 120 from disconnecting on their own when the vehicle vibrates. In other words, it can improve the reliability of the inner latch linkage mechanism.

[0042] In one embodiment, such as Figure 1 As shown, the handle 200 is a lever structure. The handle 200 includes a rotating lever 210 and a fulcrum 220. The rotating lever 210 is rotatably connected to the mounting bracket 300 through the fulcrum 220. The driver or passenger can rotate one end of the rotating lever 210 around the fulcrum 220 so that the other end of the rotating lever 210 is pressed into contact with the starter 100.

[0043] This design improves the rotation efficiency of the handle 200.

[0044] In another embodiment, the handle 200 is a rotating rod structure, which includes a rod body (not shown) and a rotating shaft (not shown). The rotating shaft is located at one end of the rod body, and the rod body is rotatably connected to the mounting bracket 300 through the rotating shaft. The end of the rod body away from the rotating shaft is defined as the actuating end. The driver or passenger can drive the actuating end to rotate around the rotating shaft so that the rod body located between the actuating end and the rotating shaft and the starter 100 are pressed together.

[0045] This design reduces the required length of the handle 200, which is beneficial for its placement within the vehicle.

[0046] In one embodiment, the inner latch linkage mechanism further includes a displacement sensor (not shown) and an electronic safety bolt (not shown). The electronic safety bolt and the displacement sensor are electrically connected to the controller. The displacement sensor is installed on the window to detect the lifting height of the window. The electronic safety bolt is used to cooperate with the door lock to lock the vehicle door and body.

[0047] When the displacement sensor detects that the height the window has fallen is less than the predetermined height, the displacement sensor can send a signal to the controller so that the controller can lock the electronic safety latch.

[0048] When the displacement sensor measures that the height the window has fallen is greater than or equal to a predetermined height, the displacement sensor can send a signal to the controller, so that the controller can unlock the electronic safety latch.

[0049] In other words, this embodiment adds an electronic safety bolt to the car door in addition to the door lock. The car door can only be opened when the electronic safety bolt is engaged and the door lock is unlocked at the same time; otherwise, the car door cannot be opened.

[0050] Thus, when the action of "controller controlling the window to lower to a predetermined height" takes a certain amount of time, even if the handle is turned 200 degrees to the second preset angle and the door lock is unlocked, the door cannot be opened. Only when the displacement sensor detects that the window has lowered to a height greater than or equal to the predetermined height and the controller controls the electronic safety latch to unlock can the door be opened.

[0051] This setup, with its double-safety mechanism for unlocking the car doors, ensures that the windows are fully lowered before the doors can be opened.
