Description

Technical Field

[0001] The present invention relates to the technical field of vehicle door handles, and in particular to a control method for a hidden vehicle door handle and a lock body. Background Art

[0002] With the rapid development of the automotive industry, vehicles are gradually becoming more intelligent and electrified. Against this background, hidden vehicle door handles have also joined the wave of intelligentization and electrification. The intelligent and electrified opening method makes the operation of the vehicle door handle more convenient and comfortable. For example, when it is necessary to open the vehicle door from the outside, external personnel authenticate with the vehicle computer through an intelligent remote control key. After successful authentication, the hidden vehicle door handle automatically rotates. Consumers only need to place their hands on the capacitive sensing area of the vehicle door handle for sensing. After successful sensing, an induction signal is triggered and sent to the body controller. The body controller issues an unlocking command to the lock body according to the induction signal to control the lock body to unlock, eliminating the process of pulling the handle during the door opening process of the traditional vehicle door handle, which is labor-saving and convenient.

[0003] However, currently, the hidden vehicle door handle and the lock body are unlocked through signal transmission. In case of emergencies (such as when the vehicle collides), the deformation of the vehicle door is likely to cause damage to the capacitive switch, resulting in the inability to normally transmit signals between the hidden vehicle door handle and the lock body. The body controller cannot control the lock body to unlock automatically, and rescue personnel cannot open the vehicle door from the outside through the vehicle door handle, resulting in the missed best rescue time and causing a large amount of property and personnel losses. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the first object of the present invention is to propose a hidden vehicle door handle. By arranging a transmission assembly between the handle cover assembly and the external opening connection mechanism of the lock body, in case of emergencies such as vehicle collision, external personnel can manually drive the handle cover assembly to move from the locked position to the unlocked position, so as to drive the external opening connection mechanism of the lock body to move through the transmission assembly to unlock the lock body, so that the vehicle door can be manually opened from the outside when the hidden vehicle door handle and the lock body cannot normally transmit signals, which is beneficial to saving the rescue time and thus reducing property and personnel losses.

[0005] The second object of the present invention is to propose a control method for a lock body.

[0006] To achieve the above object, the first aspect embodiment of the present invention proposes a hidden vehicle door handle, including:

[0007] A mounting seat, the mounting seat having a handle opening;

[0008] A handle cover assembly is movably disposed on a mounting base, and the handle cover assembly has a locked position and an unlocked position relative to the mounting base. When the handle cover assembly is in the locked position, the handle cover assembly closes the handle opening. When the handle cover assembly is in the unlocked position, the handle cover assembly opens the handle opening.

[0009] A transmission assembly is movably disposed on the mounting base, and the transmission assembly is connected between the handle cover assembly and the external opening connection mechanism of the lock body. When the handle cover assembly moves from the locked position to the unlocked position, the transmission assembly drives the external opening connection mechanism to move so as to unlock the lock body.

[0010] For the hidden door handle according to an embodiment of the present invention, a transmission assembly is connected between the handle cover assembly and the external opening connection mechanism of the lock body. The handle cover assembly is movably disposed on the mounting base. When the handle cover assembly moves from the locked position to the unlocked position, it drives the transmission assembly to move, so as to drive the external opening connection mechanism to move through the transmission assembly, thereby realizing the unlocking of the lock body. Thus, by providing a transmission assembly between the handle cover assembly and the external opening connection mechanism of the lock body, when an emergency such as a vehicle collision occurs, external personnel can manually drive the handle cover assembly to move from the locked position to the unlocked position, so as to drive the external opening connection mechanism of the lock body to move through the transmission assembly to unlock the lock body, so that the door can be manually opened from the outside when the hidden door handle and the lock body cannot transmit signals normally, which is beneficial to saving rescue time and thus reducing property and personnel losses.

[0011] According to an embodiment of the present invention, the transmission assembly includes: a first transmission member and a second transmission member. The first transmission member is rotatably disposed on the mounting base and is connected to the handle cover assembly. The second transmission member is connected between the first transmission member and the external opening connection mechanism. When the handle cover assembly moves from the locked position to the unlocked position, it drives the first transmission member to rotate, so that the second transmission member drives the external opening connection mechanism to unlock the lock body.

[0012] According to an embodiment of the present invention, the second transmission member is configured as an external opening cable.

[0013] According to an embodiment of the present invention, the handle cover assembly includes: a handle cover and a first connecting member. The handle cover is fixedly disposed on the first connecting member. The first connecting member is rotatable relative to the mounting base. The first connecting member is connected to the first transmission member. When the handle cover moves from the locked position to the unlocked position, the first connecting member drives the first transmission member to rotate.

[0014] According to an embodiment of the present invention, it further includes: a driving assembly. The driving assembly is connected to the first transmission member. The driving assembly is adapted to drive the first transmission member to rotate so that the handle cover assembly moves from the locked position to the unlocked position.

[0015] According to an embodiment of the present invention, the driving assembly includes: a driving member and a second connecting member. The driving member is fixedly provided on the mounting seat, and the second connecting member is connected between the first transmission member and the driving member. The driving member drives the first transmission member to rotate through the second connecting member, so that the handle cover assembly moves from the locked position to the unlocked position.

[0016] According to an embodiment of the present invention, it further includes: an elastic member. The elastic member is provided on the mounting seat and connected to the first transmission member. The elastic member is adapted to drive the first transmission member to rotate so that the handle cover assembly moves from the unlocked position to the locked position.

[0017] According to an embodiment of the present invention, it further includes: a controller. The controller is provided on the mounting seat, and the controller is communicatively connected to the driving assembly. The controller is used to control the driving assembly to drive the handle cover assembly to move from the locked position to the unlocked position.

[0018] According to an embodiment of the present invention, it further includes: a signal detection device. The signal detection device is provided on the mounting seat, and the signal detection device is communicatively connected to the controller. The signal detection device is adapted to obtain detection information when the handle cover assembly is in the unlocked position and send the detection information to the controller, so that the controller controls the lock body to be unlocked.

[0019] To achieve the above object, an embodiment of the second aspect of the present invention proposes a control method for a lock body. The lock body includes a motor, an unlocking mechanism, and an outward-opening connection mechanism. The unlocking mechanism is used to unlock the lock body. The unlocking mechanism is selectively connected to the motor or the outward-opening connection mechanism. The outward-opening connection mechanism is connected to the transmission assembly of the hidden door handle. The hidden door handle is the hidden door handle in the embodiment of the first aspect. The method includes: responding to a collision signal of the vehicle; controlling the motor to rotate to drive the unlocking mechanism to be connected to the outward-opening connection mechanism.

[0020] According to the control method of the lock body of the embodiment of the present invention, when the vehicle collides, the body controller responds to the collision signal and controls the motor to rotate to drive the unlocking mechanism to be connected to the outward-opening connection mechanism. The outward-opening connection mechanism of the lock body is always connected to the transmission assembly of the hidden door handle. When an external person drives the handle cover assembly to move from the locked position to the unlocked position, the transmission assembly drives the outward-opening connection mechanism of the lock body to move to drive the unlocking mechanism to be unlocked, so that the door can be manually opened from the outside when the hidden door handle and the lock body cannot normally transmit signals, which is beneficial to saving rescue time and thus reducing property and personnel losses.

[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] The hidden door handle 100 and the control method of the lock body proposed by the embodiments of the present invention will be described below with reference to the drawings.

[0040] It should be noted that in the related art, the hidden door handle 100 and the lock body are unlocked by signal transmission. However, in the event of an emergency (such as a vehicle collision), the deformation of the door is likely to cause damage to the signal detection device (such as a capacitive switch), resulting in the inability to normally transmit signals between the hidden door handle 100 and the lock body. The body controller cannot control the lock body to unlock automatically, and the rescue personnel cannot open the door from the outside through the door handle, resulting in the missed best rescue time and causing a large amount of property and personnel losses.

[0041] Based on this, the present application proposes a hidden door handle 100. By providing a transmission component 3 between the handle cover assembly 2 and the external opening connection mechanism of the lock body, when an emergency such as a vehicle collision occurs, external personnel can manually drive the handle cover assembly 2 to move from the locked position 2-1 to the unlocked position 2-2, so as to drive the external opening connection mechanism of the lock body to move through the transmission component 3 to unlock the lock body. Thus, the door can be manually opened from the outside when the hidden door handle 100 and the lock body cannot normally transmit signals, which is beneficial to saving the rescue time and thus reducing property and personnel losses.

[0042] As Figures 1 - 5 shown, the hidden door handle 100 according to the first aspect embodiment of the present invention includes: a mounting seat 1, a handle cover assembly 2, and a transmission component 3. Among them, the mounting seat 1 and the cover plate 8 define an installation space, and both the handle cover assembly 2 and the transmission component 3 are provided in the installation space. Further, the mounting seat 1 has a handle opening 11, the handle cover assembly 2 is movably provided on the mounting seat 1, and the handle cover assembly 2 has a locked position 2-1 and an unlocked position 2-2 relative to the mounting seat 1. When the handle cover assembly 2 is in the locked position 2-1, the handle cover assembly 2 closes the handle opening 11. When the handle cover assembly 2 is in the unlocked position 2-2, the handle cover assembly 2 opens the handle opening 11. The transmission component 3 is movably provided on the mounting seat 1, and the transmission component 3 is connected between the handle cover assembly 2 and the external opening connection mechanism of the lock body. When the handle cover assembly 2 moves from the locked position 2-1 to the unlocked position 2-2, the transmission component 3 drives the external opening connection mechanism to move to unlock the lock body.

[0043] Specifically, referring to Figure 1 and Figure 2 shown, the handle cover assembly 2 of the door handle is a hidden design. The handle cover assembly 2 is arranged inside the mounting seat 1. The mounting seat 1 is provided with a handle opening 11, and the handle opening 11 is correspondingly arranged with the handle cover assembly 2. The handle cover assembly 2 is movably provided on the mounting seat 1. Specifically, the handle cover assembly 2 can rotate or translate relative to the mounting seat 1. There is no specific limitation here. In the present application, the case where the handle cover assembly 2 rotates relative to the mounting seat 1 is taken as an example for illustration. As Figure 3 and Figure 4As shown, the handle cover assembly 2 can rotate relative to the mounting seat 1 in a direction away from or towards the handle opening 11, so that the handle cover assembly 2 rotates relative to the mounting seat 1 to the locked position 2-1 or the unlocked position 2-2. When the handle cover assembly 2 rotates to the locked position 2-1, as Figure 2 shown, the handle cover assembly 2 fits with the handle opening 11, and the handle cover assembly 2 closes the handle opening 11; when the handle cover assembly 2 rotates to the unlocked position 2-2, as Figure 3 shown, the handle cover assembly 2 opens the handle opening 11. With such a setting, a hidden design of the vehicle door handle is achieved, and the handle opening 11 can be closed or opened by rotating the handle cover assembly 2, which is simple to operate. It should be noted that, as Figure 5 shown, a sealing assembly 7 is provided between the handle cover assembly 2 and the handle opening 11. When the handle cover assembly 2 closes the handle opening 11, the sealing assembly 7 is used to seal the gap between the handle cover assembly 2 and the handle opening 11, thereby improving the sealing performance between the handle cover assembly 2 and the handle opening 11.

[0044] Furthermore, the hidden vehicle door handle 100 is further provided with a transmission assembly 3. The transmission assembly 3 is movably arranged on the mounting seat 1. One end of the transmission assembly 3 is connected to the handle cover assembly 2, and the other end is connected to the outside-opening connection mechanism of the lock body. With such a setting, when the handle cover assembly 2 moves, the outside-opening connection mechanism can be driven to move by using the transmission assembly 3.

[0045] It should be noted that the lock body further includes a motor and an unlocking mechanism. The unlocking mechanism is used to unlock the lock body and is selectively connected to the motor or the outside-opening connection mechanism. When the unlocking mechanism is connected to the motor, the lock body can be automatically unlocked by the vehicle body controller 5. When the unlocking mechanism is connected to the outside-opening connection mechanism, the lock body can be manually unlocked by driving the outside-opening connection mechanism to move. It can be understood that when the vehicle does not collide, the unlocking mechanism is always connected to the motor, and when the vehicle collides, the unlocking mechanism is driven to move so that it is connected to the outside-opening connection mechanism. The driving methods include but are not limited to motor driving, etc.

[0046] As a specific example, when the vehicle collides, the motor inside the lock body drives the unlocking mechanism to move, so that the unlocking mechanism is connected to the outside-opening connection mechanism. The outside rescue personnel manually push the handle cover assembly 2 to rotate from the locked position 2-1 to the unlocked position 2-2. During the rotation process of the handle cover assembly 2, the transmission assembly 3 is driven to move, the transmission assembly 3 drives the outside-opening connection mechanism to move, and the outside-opening connection mechanism is connected to the unlocking mechanism, and then the mechanical unlocking of the lock body is realized through the unlocking mechanism, which is beneficial to saving rescue time and reducing property and personnel losses.

[0047] According to the hidden door handle 100 of the embodiment of the present invention, a transmission component 3 is connected between the handle cover assembly 2 and the outward-opening connection mechanism of the lock body. The handle cover assembly 2 is movably arranged on the mounting seat 1. When the handle cover assembly 2 moves from the locked position 2-1 to the unlocked position 2-2, it drives the transmission component 3 to move, so as to drive the outward-opening connection mechanism to move through the transmission component 3, thereby realizing the unlocking of the lock body. Thus, by arranging the transmission component 3 between the handle cover assembly 2 and the outward-opening connection mechanism of the lock body, when an emergency such as a vehicle collision occurs, external personnel can manually drive the handle cover assembly 2 to move from the locked position 2-1 to the unlocked position 2-2, so as to drive the outward-opening connection mechanism of the lock body to move through the transmission component 3 to unlock the lock body, so that the door can be manually opened from the outside when the hidden door handle 100 and the lock body cannot normally transmit signals, which is beneficial to saving rescue time and thus reducing property and personnel losses.

[0048] According to an embodiment of the present invention, as Figure 1 , Figure 3 and Figure 4 shown, the transmission component 3 includes: a first transmission member 31 and a second transmission member 32. The first transmission member 31 is rotatably arranged on the mounting seat 1 and connected to the handle cover assembly 2. The second transmission member 32 is connected between the first transmission member 31 and the outward-opening connection mechanism. When the handle cover assembly 2 moves from the locked position 2-1 to the unlocked position 2-2, it drives the first transmission member 31 to rotate, so that the second transmission member 32 drives the outward-opening connection mechanism to unlock the lock body.

[0049] Specifically, as Figure 1 and Figure 3 shown, the transmission component 3 includes a first transmission member 31, and the first transmission member 31 is connected to the handle cover assembly 2. Specifically, as Figure 4 shown, the first transmission member 31 has a transmission portion 311, and the handle cover assembly 2 has a pressing rod 221. The pressing rod 221 is arranged inside the transmission portion 311, and the pressing rod 221 can slide along the inner side wall of the transmission portion 311. Further, the first transmission member 31 is rotatably arranged on the mounting seat 1. Combining Figure 1 and Figure 4 shown, when driving the handle cover assembly 2 to move from the locked position 2-1 towards the unlocked position 2-2, the pressing rod 221 rotates downward relative to the mounting seat 1. During the rotation of the pressing rod 221, the pressing rod 221 also slides relative to the transmission portion 311 and drives the first transmission member 31 to rotate.

[0050] Further, the transmission assembly 3 further includes a second transmission member 32. The second transmission member 32 is connected between the first transmission member 31 and the outward-opening connection mechanism. With such a setting, when a vehicle collision occurs, external rescue personnel push the handle cover assembly 2 to rotate, causing it to rotate from the locked position 2-1 to the unlocked position 2-2. The rotation of the handle cover assembly 2 drives the first transmission member 31 to rotate, causing the first transmission member 31 to rotate from the first position 31-1 to the second position 31-2. The rotation of the first transmission member 31 drives the second transmission member 32 to move, so as to drive the outward-opening connection mechanism to move through the second transmission member 32. And the outward-opening connection mechanism is connected to the unlocking mechanism, thereby driving the outward-opening connection mechanism to unlock the lock body. Thus, by driving the handle cover assembly 2 and cooperating with the use of the first transmission member 31 and the second transmission member 32, the mechanical unlocking of the lock body is achieved. Moreover, the transmission modes of the first transmission member 31 and the second transmission member 32 are simple and convenient, with high reliability, which is beneficial to improving the safety performance of the hidden door handle 100.

[0051] According to an embodiment of the present invention, the second transmission member 32 is configured as an outward-opening cable. That is to say, the second transmission member 32 can be configured as an outward-opening cable. The outward-opening cable is connected between the first transmission member 31 and the outward-opening connection mechanism. The outward-opening cable is made of a soft material and occupies less space, which is beneficial to improving the utilization efficiency of the installation space. Specifically, when pushing the handle cover assembly 2 to drive the first transmission member 31 to rotate, the first transmission member 31 pulls the outward-opening connection mechanism through the outward-opening cable, so as to achieve the mechanical unlocking of the lock body through the unlocking mechanism. The transmission efficiency is high, and the transmission mode is simple and convenient.

[0052] According to an embodiment of the present invention, as Figure 1 and Figure 4 shown, the handle cover assembly 2 includes: a handle cover 21 and a first connecting member 22. The handle cover 21 is fixedly provided on the first connecting member 22. The first connecting member 22 is rotatable relative to the mounting seat 1. The first connecting member 22 is connected to the first transmission member 31. When the handle cover 21 moves from the locked position 2-1 to the unlocked position 2-2, the first connecting member 22 drives the first transmission member 31 to rotate.

[0053] Specifically, the handle cover 21 is fixedly installed on the first connecting member 22. The installation methods include but are not limited to snap connection, screw connection, etc. It can be understood that the handle cover 21 is correspondingly arranged with the handle opening 11. When the handle cover 21 is in the locked position 2-1, as Figure 2 shown, the handle cover 21 fits with the handle opening 11, and the handle cover 21 closes the handle opening 11; when the handle cover 21 is in the unlocked position 2-2, as Figure 3 shown, the handle cover assembly 2 opens the handle opening 11. With such a setting, a hidden design of the handle cover 21 is realized, which occupies less space and is beneficial to improving the utilization efficiency of the installation space.

[0054] The first connecting member 22 has a rotating portion. Optionally, the rotating portion of the first connecting member 22 can be set as a rotating shaft, and the rotation of the first connecting member 22 is driven by driving the rotation of the rotating shaft. Further, the first connecting member 22 is connected to the first transmission member 31. Specifically, the first connecting member 22 has a pressing rod 221, and the first transmission member 31 has a transmission portion 311 that cooperates with the pressing rod 221. The pressing rod 221 is disposed within the transmission portion 311, and the pressing rod 221 can slide along the inner sidewall of the transmission portion 311. Combining Figure 1 and Figure 4 as shown, when the first connecting member 22 is driven to rotate from the locking position 2-1 towards the unlocking position 2-2, the pressing rod 221 rotates relative to the mounting base 1, and during the rotation of the pressing rod 221, the pressing rod 221 also slides relative to the transmission portion 311 to drive the first transmission member 31 to rotate.

[0055] As a specific example, assume that the initial position of the handle cover 21 is the locking position 2-1. When it is necessary to open the vehicle door from the outside, the external rescue personnel push the handle cover 21 to rotate, so that it rotates from the locking position 2-1 to the unlocking position 2-2. During the process of the handle cover 21 rotating from the locking position 2-1 to the unlocking position 2-2, the first connecting member 22 drives the first transmission member 31 to rotate, so that the first transmission member 31 rotates from the first position 31-1 to the second position 31-2. With such a setting, the motion transmission between the first connecting member 22 and the first transmission member 31 is realized, and the transmission structure is simple and reliable, which is beneficial to improving the safety performance of the hidden vehicle door handle 100.

[0056] According to an embodiment of the present invention, as Figure 1 、 Figure 3 and Figure 5 shown, it further includes: a driving assembly 4. The driving assembly 4 is connected to the first transmission member 31, and the driving assembly 4 is adapted to drive the first transmission member 31 to rotate so that the handle cover assembly 2 moves from the locking position 2-1 to the unlocking position 2-2.

[0057] Specifically, as Figure 5 shown, the hidden vehicle door handle 100 further includes a driving assembly 4. The driving assembly 4 is fixedly disposed inside the mounting base 1 and is connected to the first transmission member 31. Specifically, as Figure 3As shown in the figure, the first transmission member 31 is provided with a semi-circular sliding groove, and the driving assembly 4 is provided with a sliding member that is fitted and assembled with the sliding groove. The sliding member is arranged in the sliding groove and is slidable relative to the sliding groove. When the driving assembly 4 is used to drive the sliding member to slide in the sliding groove, the first transmission member 31 is rotatable relative to the mounting base 1 under the drive of the sliding member. Further, the first transmission member 31 is connected to the first connecting member 22. The first connecting member 22 is provided with a rotating shaft and a pressing rod 221. The first transmission member 31 has a transmission portion 311 that is used in cooperation with the pressing rod 221. The pressing rod 221 is arranged in the transmission portion 311, and the pressing rod 221 can slide along the inner side wall of the transmission portion 311. When the driving assembly 4 drives the first transmission member 31 to rotate, the first transmission member 31 drives the first connecting member 22 to rotate. Specifically, when the driving assembly 4 drives the first transmission member 31 to rotate from the first position 31-1 to the second position 31-2, the first connecting member 22 is driven by the first transmission member 31 to rotate from the locking position 2-1 to the unlocking position 2-2, thereby realizing the opening of the handle cover 21. With such a setting, the automatic opening of the handle cover assembly 2 is realized by setting the driving assembly 4, which improves the intelligent and electrified level of the vehicle door handle.

[0058] It should be noted that the above door opening method is applicable to the state where the vehicle is not collided. When the vehicle is not collided, the unlocking mechanism of the lock body is connected to the motor. Therefore, during the movement of the first transmission member 31, although the first transmission member 31 can drive the outward opening connection mechanism of the lock body to move through the second transmission member 32, since the unlocking mechanism of the lock body is separated from the outward opening connection mechanism, the movement of the first transmission member 31 will not drive the lock body to unlock. The lock body needs to be unlocked by the motor after unlocking authentication, thereby improving the safety performance of vehicle unlocking authentication.

[0059] According to an embodiment of the present invention, as Figure 1 and Figure 3 shown in the figure, the driving assembly 4 includes: a driving member 41 and a second connecting member 42. The driving member 41 is fixedly arranged on the mounting base 1, and the second connecting member 42 is connected between the first transmission member 31 and the driving member 41. The driving member 41 drives the first transmission member 31 to rotate through the second connecting member 42, so that the handle cover assembly 2 moves from the locking position 2-1 to the unlocking position 2-2.

[0060] Specifically, as Figure 3As shown in the figure, the driving component 4 includes a driving member 41 and a second connecting member 42. Among them, the driving member 41 can be set as a driving cylinder or a driving motor, and no specific limitation is made here. The driving member 41 is fixedly arranged on the mounting seat 1. One end of the second connecting member 42 is connected to the driving member 41, and the other end is connected to the first transmission member 31. Optionally, the second connecting member 42 can be set as a connecting rod. The driving member 41 is used to drive the second connecting member 42 to move towards the first transmission member 31. Specifically, a sliding member is provided at one end of the second connecting member 42 connected to the first transmission member 31. The first transmission member 31 is provided with a sliding groove that cooperates with the sliding member. The sliding member is arranged in the sliding groove and can slide relative to the sliding groove. When the driving member 41 drives the second connecting member 42 to move towards the first transmission member 31, the sliding member of the second connecting member 42 slides in the sliding groove, and the first transmission member 31 can rotate relative to the mounting seat 1 under the drive of the sliding member. As a specific example, when the driving member 41 drives the second connecting member 42 to move so that the first transmission member 31 rotates from the first position 31-1 to the second position 31-2, the first connecting member 22 rotates from the locking position 2-1 to the unlocking position 2-2, thereby realizing the opening of the handle cover 21. With such a setting, through the cooperation of the driving member 41 and the second connecting member 42, not only the automatic opening of the handle cover assembly 2 is realized, the intelligent and electrified level of the vehicle door handle is improved, but also the number of driving components is small and the transmission is simple and reliable, which is beneficial to improving the reliability of the automatic opening of the vehicle door handle.

[0061] According to an embodiment of the present invention, it further includes: an elastic member, which is arranged on the mounting seat 1 and connected to the first transmission member 31. The elastic member is adapted to drive the first transmission member 31 to rotate so that the handle cover assembly 2 moves from the unlocking position 2-2 to the locking position 2-1.

[0062] Specifically, the hidden vehicle door handle 100 further includes an elastic member, which is arranged on the mounting seat 1 and connected to the first transmission member 31. The elastic member is used to drive the first transmission member 31 to rotate back to place, so that the handle cover assembly 2 moves to the locking position 2-1, thereby realizing the closing of the handle opening 11.

[0063] As a specific example, assume that the initial position of the handle cover assembly 2 is the locked position 2-1. When a vehicle collision occurs, rescue personnel need to open the vehicle door from the outside. The external rescue personnel push the handle cover assembly 2 to rotate, causing it to rotate from the locked position 2-1 to the unlocked position 2-2. The rotation of the handle cover assembly 2 drives the first transmission member 31 to rotate, causing the first transmission member 31 to rotate from the first position 31-1 to the second position 31-2. The rotation of the first transmission member 31 drives the second transmission member 32 to move, so as to drive the outward opening connection mechanism to move through the second transmission member 32, and the outward opening connection mechanism is connected to the unlocking mechanism, thereby driving the outward opening connection mechanism to unlock the lock body. After the vehicle door is opened, the external rescue personnel take their hands out of the handle opening 11. Thus, under the elastic force of the elastic member, the first transmission member 31 rotates from the second position 31-2 towards the first position 31-1, thereby driving the handle cover assembly 2 to reverse, that is, driving the handle cover assembly 2 to rotate from the unlocked position 2-2 to the locked position 2-1.

[0064] As another specific example, assume that the initial position of the handle cover assembly 2 is the locked position 2-1, and the driving member 41 is a driving motor for illustration. When a vehicle collision does not occur, the driving motor drives the second connecting member 42 to move, so that when the first transmission member 31 rotates from the first position 31-1 to the second position 31-2, the first connecting member 22 rotates from the locked position 2-1 to the unlocked position 2-2, thereby realizing the opening of the handle cover 21. Consumers only need to place their hands on the capacitive sensing area of the vehicle door handle for sensing. When the sensing is successful, an induction signal is triggered and sent to the controller 5. The controller 5 issues an unlocking instruction to the lock body according to the induction signal to control the lock body to unlock. After the vehicle door is opened, the driving motor rotates in reverse. Thus, under the elastic force of the elastic member, the first transmission member 31 rotates from the second position 31-2 towards the first position 31-1, thereby driving the handle cover assembly 2 to reverse, that is, driving the handle cover assembly 2 to rotate from the unlocked position 2-2 to the locked position 2-1.

[0065] Thus, by providing the elastic member, the automatic return of the handle cover assembly 2 can be realized, that is, rotating from the unlocked position 2-2 to the locked position 2-1, which not only meets the functional requirements, but also has a simple and reliable structure and low cost.

[0066] According to an embodiment of the present invention, as Figure 1 、 Figure 3 and Figure 5 shown, it further includes: a controller 5, the controller 5 is disposed on the mounting seat 1, and the controller 5 is communicatively connected to the driving assembly 4. The controller 5 is used to control the driving assembly 4 to drive the handle cover assembly 2 to move from the locked position 2-1 to the unlocked position 2-2.

[0067] Specifically, the hidden door handle 100 further includes a controller 5. The controller 5 is communicatively connected to the driving assembly 4. Specifically, taking the driving assembly 4 including a driving motor as an example, the controller 5 can communicate with the driving motor in the driving assembly 4, and the controller 5 can also communicate wirelessly with the smart key carried by the vehicle owner. For example, the controller 5 can communicate with the smart key via Bluetooth. As a specific example, when the vehicle owner needs to open the door from the outside, the vehicle owner authenticates with the controller 5 through the smart key. After successful authentication, the controller 5 sends an opening signal to the driving motor. The driving motor drives the first transmission member 31 to rotate from the first position 31-1 towards the second position 31-2 according to the opening signal, so as to drive the first connecting member 22 to drive the handle cover 21 to rotate from the locked position 2-1 towards the unlocked position 2-2, thereby realizing the opening of the handle cover 21. During the rotation of the handle cover 21, the unlocked position 2-2 is the maximum position where the handle cover 21 can be opened. When the handle cover 21 rotates to the unlocked position 2-2, the driving motor stops rotating, so that the handle cover 21 remains in the unlocked position 2-2. Thus, by setting the controller 5, the automatic control of the driving assembly 4 is realized, the automation degree of the opening of the hidden door handle 100 is improved, and the convenience and comfort of the operation are improved.

[0068] According to an embodiment of the present invention, as Figure 1 and Figure 5 shown, it further includes: a signal detection device 6. The signal detection device 6 is arranged on the mounting seat 1, and the signal detection device 6 is communicatively connected to the controller 5. The signal detection device 6 is adapted to obtain detection information when the handle cover assembly 2 is in the unlocked position 2-2, and send the detection information to the controller 5, so that the controller 5 controls the lock body to unlock.

[0069] Specifically, the hidden door handle 100 further includes a signal detection device 6. Optionally, the signal detection device 6 can be set as a capacitive switch. In this application, the capacitive switch is taken as an example for illustration. The capacitive switch is arranged on the mounting seat 1 and located at the handle opening 11. With such a setting, when the handle cover assembly 2 is opened, it is convenient for consumers to place their hands on the capacitive sensing area of the capacitive switch. The capacitive switch is used to obtain detection information when the handle cover assembly 2 is in the unlocked position 2-2, that is, to obtain a capacitive sensing signal. Specifically, when the handle cover 21 rotates to the unlocked position 2-2, the consumer places their hand on the capacitive sensing area of the capacitive switch of the door handle. When the sensing is successful, an induction signal is triggered and sent to the controller 5. The controller 5 issues an unlocking instruction to the lock body according to the induction signal to control the lock body to unlock. With such a setting, the authentication and unlocking of the door are realized by setting the signal detection device 6, and the safety performance of vehicle unlocking is improved.

[0070] It should be noted that after the vehicle is unlocked, the lock body control system feeds back the unlocking signal to the controller 5. If the door is an ordinary door, the vehicle owner can simply pull the handle to open the door; if the door is an electric door, the controller 5 drives the door motor to open the door.

[0071] Figure 6 FIG. is a flowchart of a control method for a lock body according to an embodiment of the present invention. As Figure 6 shown, the control method for the lock body includes the following steps:

[0072] Step S101, responding to a collision signal of the vehicle.

[0073] Step S102, controlling the motor to rotate to drive the unlocking mechanism to be connected to the outward-opening connection mechanism.

[0074] It should be noted that the lock body includes a motor, an unlocking mechanism, and an outward-opening connection mechanism. The unlocking mechanism is used to unlock the lock body. The unlocking mechanism is selectively connected to the motor or the outward-opening connection mechanism. The outward-opening connection mechanism is connected to the transmission component 3 of the hidden door handle 100, and the hidden door handle 100 is the hidden door handle 100 in the embodiment of the first aspect.

[0075] Specifically, the unlocking mechanism is selectively connected to the motor or the outward-opening connection mechanism. When the unlocking mechanism is connected to the motor, the lock body can be automatically unlocked by the body controller 5. When the unlocking mechanism is connected to the outward-opening connection mechanism, the lock body can be manually unlocked by driving the outward-opening connection mechanism to move. It can be understood that when the vehicle does not collide, the unlocking mechanism is always connected to the motor, and when the vehicle collides, the motor is controlled to rotate to drive the unlocking mechanism to be connected to the outward-opening connection mechanism. The driving method includes but is not limited to motor driving, etc.

[0076] With such a setting, when the vehicle collides, the motor inside the lock body drives the unlocking mechanism to move, so that the unlocking mechanism is connected to the outward-opening connection mechanism. The external rescue personnel manually push the handle cover assembly 2 to rotate from the locked position 2-1 to the unlocked position 2-2. During the rotation of the handle cover assembly 2, the transmission component 3 is driven to move. The transmission component 3 drives the outward-opening connection mechanism to move. The outward-opening connection mechanism is connected to the unlocking mechanism, and then the mechanical unlocking of the lock body is realized through the unlocking mechanism, which is beneficial to saving rescue time and reducing property and personnel losses.

[0077] According to the control method of the lock body according to an embodiment of the present invention, when a vehicle collision occurs, the body controller 5 responds to the collision signal, controls the motor to rotate to drive the unlocking mechanism to be connected to the outward-opening connection mechanism, and the outward-opening connection mechanism of the lock body is always connected to the transmission assembly 3 of the concealed door handle 100. When an external person drives the handle cover assembly 2 to move from the locked position 2-1 to the unlocked position 2-2, the transmission assembly 3 drives the outward-opening connection mechanism of the lock body to move to drive the unlocking mechanism to unlock, so that the door can be manually opened from the outside when the concealed door handle 100 and the lock body cannot normally transmit signals, which is beneficial to saving rescue time and thus reducing property and personnel losses.
