TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle door lock, in particular to a vehicle door unlocking mechanism and a vehicle door handle. BACKGROUND

[0002] The current vehicle door can realize electronic unlocking of the vehicle door by pressing the switch at the vehicle door handle. Although this method is more convenient than unlocking the vehicle door by key (mechanical unlocking), once power failure or electronic unlocking failure occurs, the vehicle door will be difficult to open. Therefore, the vehicle door needs to have both electronic unlocking and mechanical unlocking, to ensure convenience through electronic unlocking and to deal with special situations through mechanical unlocking.

[0003] The existing electronic unlocking module and mechanical lock core module on the vehicle door handle are often separated, with the electronic unlocking module located on one side and the mechanical lock core module located on the other side. Due to infrequent use and safety considerations, they are usually set in a hidden position of the vehicle door handle or covered by a cover, such as the patent application with publication number CN106687656A, which sets a lock core at the handle for key unlocking, and a cover element can cover the lock core. This form of separate setting of the electronic unlocking module and the mechanical lock core module requires two openings on the vehicle door handle for installing the above unlocking mechanisms, which sometimes affects the simple appearance of the vehicle door handle.

[0027] A vehicle door unlocking mechanism, which is installed in the vehicle door handle as shown in Figure 1 , Figure 2The shown vehicle door handle, and including electronic unlocking module 1, mechanical lock core module 2, cover 3 and handle base 4, electronic unlocking module 1 and mechanical lock core module 2 are installed on the handle base 4 in the same opening of the vehicle door handle (the above-mentioned modules can be installed in other positions of the vehicle door, even the unlocking mechanism can be equivalent), and the cover 3 is located at the opening to shield the inside of the opening.

[0028] In combination Figure 3 , the electronic unlocking module 1 is installed on the handle base 4 through the mounting seat 5, in combination Figure 6 , the mounting seat 5 includes a mounting portion 51 near the front end of the cover 3, and a locking portion 52 away from the cover 3 at the rear end.

[0029] Among them, the electronic unlocking module 1 is installed in the mounting portion 51, the cover 3 can be pressed and moved relative to the mounting portion 51 until the electronic unlocking module 1 is triggered, and the first spring 53 is further provided between the mounting portion 51 and the cover 3 for resetting the cover 3.

[0030] The locking portion 52 is installed with a pawl 6 that can rotate, the pawl 6 can cooperate with the handle base 4 when it rotates to a certain angle to prevent the mounting seat 5 from moving forward to achieve locking, and the cover 3 can be pressed in another way and the mounting seat 5 is moved relative to the handle base 4 until the pawl 6 is out of contact with the handle base 4 to achieve unlocking (the pressing method is preferably distinguished by different forces, for example, by overcoming the elastic force of the first spring 53 to trigger the electronic unlocking module 1, and by overcoming the elastic force of the second spring 54 to achieve unlocking, in addition, the pressing time can also be distinguished to achieve the above-mentioned effect, but the effect is not as ideal as the former way, the specific pressing method is not limited as long as it can trigger the electronic unlocking module 1 without unlocking the pawl 6), and the second spring 54 is installed between the locking portion 52 and the handle base 4, which can provide an elastic force for moving the mounting seat 5 together with the cover 3 outward in the unlocked state, and the mechanical lock core module 2 is exposed at the opening as Figure 4 shown.

[0031] On the basis of the above, the specific structure of the present scheme further comprises: the two ends of the first spring 53 are in contact with the rear end face of the cover 3 and the front end face of the mounting portion 51 respectively, in combination Figure 5 , Figure 6 , the front end face of the mounting portion 51 is further provided with a connecting groove 511, and the rear end face of the cover 3 is provided with a limiting connection buckle 31, the limiting connection buckle 31 passes through the connecting groove 511 and the rear end thereof is provided with a limiting block 32, the width of the limiting block 32 is greater than the width of the connecting groove 511 for preventing the limiting connection buckle 31 from disengaging from the connecting groove 511 and keeping it at the opening to avoid disengaging from the handle. In addition, the cover 3 and the mounting portion 51 can also be connected by triggering the balance lever 514 to rotate.

[0032] Similarly combined Figure 5 , Figure 6 The mounting part 51 also includes a mounting cavity 512, in which the electronic unlocking module 1 is installed. A trigger channel 513 is provided at the front end of the mounting cavity 512, and a rearwardly extending trigger rod 33 is provided at the rear end of the cover 3. The trigger rod 33 extends into the trigger channel 513. When the cover 3 is pressed, the trigger rod 33 can move toward the electronic unlocking module 1 until it contacts the electronic unlocking module 1 and triggers the electronic unlocking module 1. The electronic unlocking module 1 can use a micro switch to generate an electrical signal by being pressed to unlock the car door. Electronic unlocking of car doors is currently widely used in vehicles and will not be described in detail here.

[0033] Regarding the specific structure of the locking part 52, in conjunction with Figure 3 The handle base 4 has a mounting channel, and the locking part 52 passes through the mounting channel, positioning the pawl 6 at the rear end of the mounting channel (the rear end of the mounting base 5 has two parallel guide blocks 521, and the pawl 6 is rotatably mounted between the two guide blocks 521). (This is followed by a seemingly unrelated sentence about combining the two parts.) Figure 7 The pawl 6 also includes an adapter section 61. When the pawl part is disengaged from the handle base 4, the pawl 6 rotates under the action of force A (preferably, the rear end of the handle base 4 is also connected to an elastic pressure member 7, which is used to provide force A. Alternatively, the pawl 6 can be placed vertically and rotated by gravity). When the mounting base 5 moves forward, the adapter section 61 can be aligned and enter the mounting channel.

[0034] More specifically, the pawl of the pawl 6 includes a smooth section 62 and a limiting section 63. When in the locked state, the smooth section 62 contacts the inner wall of the mounting channel to prevent the pawl 6 from rotating under the force A. At the same time, the limiting section 63 contacts the outer wall of the rear end of the mounting channel to prevent the pawl 6 and the mounting base 5 from moving forward.

[0035] The pawl 6 also includes a guide surface 64. When the pawl part disengages from the handle base 4, the pawl 6 rotates under force and the guide surface 64 is aligned with the rear outer wall of the mounting channel. When the mounting base 5 moves forward, the rear outer wall of the mounting channel can contact the guide surface 64 and drive the pawl 6 to rotate, ultimately aligning the adapter section 61 with the mounting channel.

[0036] A car door handle is equipped with the aforementioned car door unlocking mechanism. In order to meet relevant regulations and to facilitate opening the car door, the car door handle is also provided with a recessed hand grip space 8, which is used by the user to insert their hand and apply force to the car door handle to open the car door.

[0037] When using this solution, it should be combined with... Figure 3Normally, the car door is unlocked electronically. Specifically, pressing the cover 3 with a certain amount of force overcomes the elasticity of the first spring 53 and triggers the electronic unlocking module 1 to unlock the door. In special circumstances, such as a power outage or a malfunction of the electronic unlocking module 1 preventing the door from being opened electronically, pressing the cover 3 with even greater force overcomes the elasticity of the second spring 54 and... Figure 8 As shown in state a, moving the mounting base 5 backward and continuously pressing it will cause the pawl 6 to disengage from the handle base 4, as shown in state b. At this time, the pawl 6 is unobstructed and can rotate counterclockwise under force A, aligning the guide surface 64 with the rear outer wall of the mounting channel. After stopping pressing the cover, the elastic force of the second spring 54 will cause the pawl 6 to move forward, as shown in state c, and continue to rotate counterclockwise through the guide surface 64 to contact the rear outer wall of the mounting channel, until the adapter section 61 faces the mounting channel and enters the mounting channel, as shown in state d. This will cause the cover 3 and even the entire mounting base 5 to detach from the opening and proceed as shown in state b. Figure 4 The mechanical lock cylinder module 2 is exposed, allowing users to mechanically unlock the car door by inserting a key. This removable mounting bracket 5 also facilitates the replacement or repair of the electronic unlocking module 1. During subsequent installation, the pawl 6 is reversed before inserting the mounting bracket 5, making it easy to use.

[0038] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
