Description

Technical Field

[0001] The present invention belongs to the technical field of automobile parts and relates to a door lock handle assembly, in particular to a vehicle door and a vehicle having the door lock handle assembly. Background Art

[0002] In existing technology, door locks on new energy vehicles generally incorporate electronic door locks in addition to mechanical handle door locks. When the vehicle is parked, the electronic door lock allows users to open the door smoothly and conveniently simply by touching it. However, the electronic and mechanical door locks on existing new energy vehicles are located in different locations, and the mechanical door locks are often concealed due to the overall design of the vehicle. Under normal circumstances, it is not a problem for users to unlock the door using only the electronic door lock.

[0003] However, in dangerous situations, such as when the car collides, falls into water, or catches fire, the electronic door lock will fail due to power failure or circuit short circuit, and the door cannot be opened. The mechanical door lock is hidden, which makes it difficult for passengers who are not familiar with the vehicle to quickly and accurately find the location of the corresponding mechanical door lock when the above situation occurs. As a result, the occupants of the car cannot escape in time, and the best time to open the door and escape is delayed. Therefore, there are still corresponding safety hazards. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a door lock handle assembly that integrates electronic unlocking and mechanical unlocking to avoid safety hazards.

[0005] The object of the present invention can be achieved through the following technical solutions: A door lock handle assembly, comprising:

[0006] The housing has a mounting plane, which is recessed downward along the mounting plane to form a cavity, and a through groove communicating with the cavity is provided on the bottom of the cavity;

[0007] The door lock handle is rotatably connected to the concave cavity, with one end being a handle end and the other end passing through the through slot, and an unlocking member connected to the door lock body is provided at the end, wherein the door lock handle is rotated to pull the door lock body through the unlocking member;

[0008] An electronic unlocking module is mounted on the back of the cavity bottom. The electronic unlocking module includes a substrate, a handle motion detection module, and a connector module provided on the substrate. The handle motion detection module is used to detect the movement of the door lock handle, and the connector module is used to exchange signals with an external controller.

[0009] Under normal conditions, the outer end surface of the handle end of the door lock handle is flush with the installation plane; when the handle end of the door lock handle is rotated outward by a preset angle by an external force, the door lock handle drives the unlocking member to move and at the same time drives the door lock body to be unlocked through the unlocking member; when the handle end of the door lock handle is rotated inward by a preset angle by an external force, the handle action detection module detects the unlocking signal caused by the inward rotation of the door lock handle and sends it to the outside through the connector module.

[0010] In the above-mentioned door lock handle assembly, the handle action detection module is a conductive rubber switch, and a trigger area is provided on the substrate. A trigger portion is provided on the conductive rubber switch and is positioned relative to the trigger area. There is a gap between the trigger portion and the trigger area. Pressing the hand end of the door lock handle causes the trigger portion to contact the trigger area to generate an unlocking signal.

[0011] In the above-mentioned door lock handle assembly, the trigger portion is deformed under the pressure generated when the hand end of the door lock handle is pressed, and contacts the trigger area to generate an unlocking signal.

[0012] In the above-mentioned door lock handle assembly, the handle motion detection module is a micro switch, and pressing the hand end of the door lock handle drives the micro switch to generate an unlocking signal.

[0013] In the above-mentioned door lock handle assembly, a guide bracket and a reset spring for resetting the guide bracket are provided between the door lock handle and the electronic unlocking module, wherein the two ends of the guide bracket are respectively abutted against the door lock handle and the handle action detection module, and the two ends of the reset spring are respectively abutted against the guide bracket and the electronic unlocking module.

[0035] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] like Figures 1 to 7 As shown, the present invention provides a door lock handle assembly, comprising:

[0038] The housing 100 has a mounting plane 110 , which is recessed downward along the mounting plane 110 to form a cavity 120 , and a through slot 130 communicating with the cavity 120 is provided on the bottom of the cavity 120 ;

[0039] The door lock handle 200 is rotatably connected to the concave cavity 120, with one end being a handle end and the other end passing through the through slot 130. An unlocking member 210 connected to the door lock body is provided at this end. Rotating the door lock handle 200 pulls the door lock body through the unlocking member 210.

[0040] The electronic unlocking module 300 is mounted on the back side of the bottom of the cavity 120. The electronic unlocking module 300 includes a substrate 310, a handle motion detection module and a connector module provided on the substrate 310. The handle motion detection module is used to detect the movement of the door lock handle 200, and the connector module is used to exchange signals with an external controller.

[0041] Under normal conditions, the outer end surface of the starting end of the door lock handle 200 is flush with the installation plane 110; when the starting end of the door lock handle 200 is rotated outward by a preset angle by an external force, the door lock handle 200 drives the unlocking member 210 to move and at the same time drives the door lock body to be unlocked through the unlocking member 210; when the starting end of the door lock handle 200 is rotated inward by a preset angle by an external force, the handle action detection module detects the unlocking signal caused by the inward rotation of the door lock handle 200 and sends it to the outside through the connector module.

[0042] It is worth mentioning that mechanical unlocking is achieved by turning the hand end to cause the door lock handle 200 to rotate, and pulling the door lock body through the unlocking member 210; electronic unlocking is achieved by pressing the hand end on the door lock handle 200 to cause the trigger part 321 to contact the trigger area 311 to generate an unlocking signal, wherein the rotation direction of the door lock handle 200 during mechanical unlocking is opposite to the rotation direction of the door lock handle 200 during electronic unlocking.

[0043] It is worth mentioning that according to the principle of mechanical unlocking, the user places his hand on the hand end and causes the hand end to rotate in a direction away from the cavity 120, thereby pulling the unlocking member 210, thereby opening the door lock body and finally opening the car door.

[0044] According to the principle of electronic unlocking, when the user presses the upper end of the door lock handle 200, the door lock handle 200 is pressed down to cause the trigger part 321 to contact the trigger area 311 on the substrate 310. The handle action detection module detects the unlocking signal caused by the inward rotation of the door lock handle 200 and sends it to the outside through the connector module. The body controller receives the unlocking signal, so that the electric actuator in the car door moves, and the output end of the electric actuator is connected to the door lock body in the car door, thereby realizing the opening of the door lock body and finally the opening of the car door.

[0045] The present invention provides a door lock handle assembly that integrates mechanical unlocking and electronic unlocking. The unlocking direction of the mechanical unlocking is opposite to that of the electronic unlocking, and the two do not interfere with each other, thereby avoiding the occurrence of safety hazards.

[0046] Preferably, the handle action detection module is a conductive rubber switch 320, and a trigger area 311 is provided on the substrate 310. A trigger portion 321 is provided on the conductive rubber switch 320 and is positioned relative to the trigger area 311, wherein there is a gap between the trigger portion 321 and the trigger area 311. Pressing the hand end of the door lock handle 200 causes the trigger portion 321 to contact the trigger area 311 to generate an unlocking signal.

[0047] It is further pointed out that the trigger portion 321 is deformed under the pressure generated when the hand end of the door lock handle 200 is pressed, and contacts the trigger area 311 to generate an unlocking signal.

[0048] In another preferred embodiment, the handle motion detection module is a micro switch, and pressing the hand end of the door lock handle 200 drives the micro switch to generate an unlocking signal.
