[0037] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] The present application provides a kind of vehicle door unlocking device, vehicle door and vehicle provided by specific embodiment and its application scene, which will be described in detail below in conjunction with the drawings.

[0039] As Figure 1 And Figure 2 As shown in the present application, a vehicle door unlocking device is provided, comprising: pressing assembly 1, sensing assembly 2, support assembly 3 and damping member 4;Pressing assembly 1 is connected to support assembly 3, damping member 4 is arranged between pressing assembly 1 and support assembly, damping member 4 has a predetermined elastic coefficient, pressing assembly 1 can move relative to support assembly 3 to press damping member 4, damping member 4 can be telescopic deformation between pressing assembly 1 and support assembly 3, sensing assembly 2 is arranged between pressing assembly 1 and support assembly 3, sensing assembly 2 is suitable for electrically connected with vehicle door lock, sensing assembly 2 can unlock vehicle door lock based on the pressing force suffered by pressing assembly 1.

[0040] In the embodiment of the present application, when the user presses the pressing assembly 1 to unlock the door, the sensing assembly 2 senses the pressing force of the pressing assembly 1, and then unlocks the door lock. In this process, the damping member 4 is pushed by the pressing assembly 1 and is compressed to deform. The user can perceive a certain distance of displacement with the movement of the pressing assembly 1, and at the same time, after the pressing is completed, the damping member 4 can rebound and feedback a certain rebound force to the pressing assembly 1, so that the user can clearly perceive the end of the pressing action, thereby knowing that the door lock is successfully unlocked, improving the feedback of the door unlocking device to the user, and thereby improving the user's experience.

[0041] In specific applications, the pressing assembly 1 is connected to the supporting assembly 3 and can move relative to the supporting assembly 3 to press the damping member 4. Specifically, it can be at least one of sliding connection, clearance fit connection, transition fit connection, etc. Those skilled in the art can set it according to actual needs, and the present application does not limit it.

[0042] It should be explained that the damping member 4 has a preset elastic coefficient and can be stretched and deformed between the pressing assembly 1 and the supporting assembly 3. Specifically, the elastic coefficient of the damping member 4 can make the damping member 4 shrink and deform a large enough amount when it is extruded by the pressing assembly 1, so that the pressing assembly 1 can have a certain amount of displacement when pressed by the user, so that the user can clearly perceive the effect of the pressing action. At the same time, after the user finishes pressing, the damping member 4 can rebound to restore its original shape. In this process, the damping member 4 can give the pressing assembly 1 a certain rebound force, so that the user can clearly perceive the resetting of the pressing assembly 1 with the rebound of the damping member 4, so that the user can clearly perceive the end of the pressing action, thereby knowing that the door lock is successfully unlocked, improving the feedback of the door unlocking device to the user, and thereby improving the user's experience.

[0043] It should be noted that the extrusion of the pressing assembly 1 on the damping member 4 causes the damping member 4 to deform, and the deformation of the damping member 4 is within its elastic limit, i.e. the damping member 4 can restore its original shape after being extruded.

[0044] In specific applications, the preset elastic coefficient of the damping member 4 is determined according to the size of the damping member 4 and the elastic modulus of the damping member 4. In other words, the preset elastic coefficient of the damping member 4 is related to the deformation size of the damping member 4 and the elastic modulus of the material of the damping member 4. When designing, the corresponding elastic coefficient needs to be set according to the deformation range of the damping member 4 and the elastic modulus of the damping member 4, so as to ensure that the deformation of the damping member 4 can be clearly perceived by the user, and at the same time, the damping member 4 will not be too large, causing excessive space occupation.

[0045] It can be understood that the sensing assembly 2 knows the unlocking action of the user by sensing the pressing force of the pressing assembly 1, and then opens the door lock, so that the sensing assembly 2 can be combined by the pressing force detection unit and the control unit, that is, the sensing member and the circuit board are formed separately, or the sensing area is arranged on the control unit, that is, the integrated control unit. Those skilled in the art can set it according to the actual needs, and the present application does not limit it.

[0046] When the sensing assembly 2 is composed of a sensing member and a circuit board, the sensing member can be arranged in the pressing assembly 1 to facilitate the detection of the pressing force, and the circuit board can be arranged in the supporting assembly to facilitate the protection of the circuit board and improve the reliability of the door unlocking device.

[0047] In some embodiments of the present application, the elastic coefficient of the damping member 4 is K, which satisfies: 10N / mm≤K≤15N / mm.

[0048] In the embodiments of the present application, by setting the elastic coefficient K of the damping member 4 within a reasonable range, when the user presses the pressing assembly 1 to unlock the door lock, a certain amount of displacement perception and a certain amount of rebound force can be obtained, so that the user can perceive the pressing process more clearly, and the user can know that the door unlocking is successful through the touch, thereby improving the user experience.

[0049] It should be explained that when the elastic coefficient K of the damping member 4 is less than 10N / mm, since the elastic coefficient K of the damping member 4 is too small, when the pressing force of the user is unchanged, the damping member 4 cannot give the user a large enough rebound force when the user presses, so that the user's perception is not obvious enough. When the elastic coefficient K of the damping member 4 is greater than 15N / mm, since the elastic coefficient K of the damping member 4 is too large, when the pressing force of the user is unchanged, the deformation amount of the damping member 4 is small when the user presses, so that the user cannot clearly perceive the displacement in the pressing process, thereby making the user's perception not obvious enough.

[0050] In specific applications, the damping member 4 can be at least one of a spring, a rubber member, a foam member, a thermoplastic elastomer, etc. Those skilled in the art can set it according to the actual needs, and the present application does not limit it.

[0051] It can be understood that the damping member 4 can be provided with one or more, and those skilled in the art can set it according to the actual needs, and the present application does not limit it.

[0052] In some embodiments of the present application, the specific material of the damping member 4 is rubber, so that the weight of the damping member 4 is lighter, the structure is simple, the cost is low, and the structure is reliable.

[0053] In a specific application, the elastic coefficient K of the damping member 4 can be set to any value or any value between two values of 10 N / mm, 10.5 N / mm, 11 N / mm, 11.5 N / mm, 12 N / mm, 12.5 N / mm, 13 N / mm, 13.5 N / mm, 14 N / mm, 14.5 N / mm, 15 N / mm, etc.

[0054] As shown in Figure 3 and Figure 4 In some embodiments of the present application, the damping member 4 is provided in plurality, and is arranged between the pressing assembly 1 and the support assembly 3 in the movement direction X of the pressing assembly 1.

[0055] In the embodiments of the present application, by providing the damping member 4 in plurality, and arranging the plurality of damping members 4 between the pressing assembly 1 and the support assembly 3 in the movement direction X of the pressing assembly 1, the elastic coefficient of each damping member 4 can be set smaller while meeting the elastic requirement, and the service life of each damping member 4 is longer.

[0056] In a specific application, the number of damping members 4 can be set to any value of 2, 3, 4, 5, 6, etc.

[0057] It can be understood that when the plurality of damping members 4 are arranged in plurality, the pressing assembly 1 is pressed by the user, the plurality of damping members 4 are simultaneously stressed, the stress is more uniform, the feedback force is also uniform, and the structure is stable.

[0058] In some embodiments of the present application, the damping member 4 is provided in three, two of which are arranged on both sides of the first hole 311, and the remaining damping member 4 forms a triangle with them, so that when pressed, the pressing assembly 1 can form a whole translation, avoiding the inclination during movement, forming friction with the first support member 31, and ensuring the stability of the structure.

[0059] As shown in Figure 2 , Figure 3 and Figure 4 In some embodiments of the present application, the side of the pressing assembly 1 facing the support assembly 3 is provided with a mounting portion 123, the support assembly 3 is provided with an abutting portion 312, the abutting portion 312 is in guiding connection with the mounting portion 123; the damping member 4 is installed in the mounting portion 123, the abutting portion 312 at least partially abuts against the damping member 4, and the damping member 4 can be elastically deformed between the mounting portion 123 and the abutting portion 312.

[0060] In the embodiments of the present application, the damping member 4 is installed in the mounting portion 123, thereby ensuring the stability of the damping member 4, the abutting portion 312 at least partially abuts against the damping member 4, and the damping member 4 can be elastically deformed between the mounting portion 123 and the abutting portion 312, so that when the pressing assembly 1 extrudes the damping member 4, the damping member 4 can stably deform, and after the user finishes pressing, the damping member 4 can smoothly return to the original state, and the pressing assembly 1 is pushed back to the original position by the mounting portion 123.

[0061] In specific applications, the damping member 4 can be installed in the mounting portion 123 in a clamping, fixed connection, bonding or the like manner, as long as the damping member 4 can stably deform, and a person skilled in the art can set it according to actual needs, which is not limited in the present application.

[0062] It should be noted that the deformed part of the damping member 4 is mainly arranged in the part where the pressing assembly 1 and the supporting assembly 3 move relative to each other.

[0063] It can be understood that the abutting portion 312 is guidedly connected with the mounting portion 123, thereby ensuring the accuracy of the movement of the pressing assembly 1 while the abutting portion 312 can move relative to the mounting portion 123, and avoiding the deflection of the pressing assembly 1 when moving.

[0064] As shown in Figure 3 , Figure 4 and Figure 6 , in some embodiments of the present application, the damping member 4 comprises a mounting segment 41, an abutting segment 43, and a connecting segment 42 connected between the mounting segment 41 and the abutting segment 43, and along the movement direction X of the pressing assembly 1, the mounting portion 123 is provided with a first clamping groove 1231, a second clamping groove 1232, and an opening 1233 communicating the first clamping groove 1231 and the second clamping groove 1232; the mounting segment 41 is installed in the first clamping groove 1231, the connecting segment 42 is installed in the opening 1233, and the abutting segment 43 is arranged in the second clamping groove 1232; the abutting portion 312 is provided with a protrusion 3121, and along the movement direction X of the pressing assembly 1, the protrusion 3121 is guidedly connected with the second clamping groove 1232 and abuts against the abutting segment 43.

[0065] In the embodiments of the present application, the mounting section 41 is mounted in the first clamping groove 1231, and the connecting section 42 is mounted in the opening 1233, thereby ensuring the mounting stability of the damping member 4, so that the damping member 4 does not move between the pressing assembly 1 and the supporting assembly 3 when deformed; meanwhile, the abutting section 43 is arranged in the second clamping groove 1232; the protrusion 3121 is arranged in the abutting portion 312, and is guided and connected to the second clamping groove 1232 along the movement direction X of the pressing assembly 1, and abuts against the abutting section 43, so that when the pressing assembly 1 presses the abutting section 43 of the damping member 4, the abutting section 43 can be deformed, and after the user finishes pressing, the abutting section 43 can rebound to push the pressing assembly 1 back to the original position.

[0066] In specific applications, the protrusion 3121 and the second clamping groove 1232 correspond to each other in position and are matched with each other in shape, so that the protrusion 3121 can be inserted into the second clamping groove 1232 to form a guided connection, thereby ensuring the accuracy of the movement of the pressing assembly 1, reducing deviation, and improving the reliability of the vehicle door unlocking device.

[0067] It should be explained that the first clamping groove 1231, the second clamping groove 1232 and the opening 1233 are matched with the shapes of the mounting section 41, the connecting section 42 and the abutting section 43 respectively, thereby ensuring the stability of the connection.

[0068] In some embodiments of the present application, the protrusion 3121 is provided with a second opening on the side facing the damping member 4, the abutting section 43 is arranged between the second opening of the protrusion 3121 and the groove wall of the second clamping groove 1232, and can stretch and contract along the movement direction X of the pressing assembly 1, thereby improving the smooth pushing of the pressing assembly 1 when the damping member 4 rebounds, and reducing the possibility of deviation of the movement of the pressing assembly 1.

[0069] As shown in FIG. 1, Figure 4 In some embodiments of the present application, the cross-sectional area of the mounting section 41 is greater than that of the connecting section 42 along the direction perpendicular to the movement direction X of the pressing assembly 1, and the cross-sectional area of the abutting section 43 is greater than that of the connecting section 42, thereby ensuring the stable mounting of the damping member 4 while providing sufficient deformation, so that the pressing assembly 1 has sufficient displacement, and can provide sufficient rebound force to the pressing assembly 1, thereby enabling the user to clearly perceive the pressing process and know that the vehicle door unlocking is successful through touch.

[0070] Specifically, the damping member 4 is in the shape of a tire as a whole, thereby ensuring stable mounting while meeting the requirement of sufficient deformation to provide a certain displacement space and rebound force to the pressing assembly 1, so that the user can clearly perceive the touch of pressing and improve the user experience.

[0071] As shown in FIG. 1, Figure 2 , Figure 7and Figure 8 As shown in the figures, in some embodiments of the present application, the sensing assembly 2 comprises a sensing member 21 arranged in the pressing assembly 1 and a circuit board 22 arranged in the supporting assembly 3, the sensing member 21 is electrically connected to the circuit board 22, the sensing member 21 can sense the pressing force of the pressing assembly 1 and send a pressing signal to the circuit board 22, and the circuit board 22 can unlock the car door lock based on the pressing signal of the sensing member 21.

[0072] In the embodiments of the present application, the sensing member 21 is arranged in the pressing assembly 1, which is convenient for sensing the pressing force of the pressing assembly 1, and the circuit board 22 is arranged in the supporting assembly 3, which is convenient for protecting the circuit board 22, and the separate arrangement is more convenient for installation.

[0073] In specific applications, the sensing member 21 can be at least one of a diaphragm type pressure sensor, a spring type pressure sensor, a resistance type pressure sensor, a capacitance type pressure sensor, a piezoelectric type pressure sensor, and an optical fiber pressure sensor, and a person skilled in the art can select according to actual needs, which is not limited in the present application.

[0074] In specific applications, the circuit board 22 can be at least one of a printed circuit board (PCB), a flexible circuit board (FPC), a metal-based circuit board (MCPCB), and the like, and a person skilled in the art can select according to actual needs, which is not limited in the present application.

[0075] It should be explained that the sensing member 21 is arranged in the pressing assembly 1, and when subjected to the pressing force, the pressing assembly 1 moves relative to the supporting assembly 3, so that the sensing member 21 senses the pressing force of the pressing assembly 1. The sensing member 21 can be at least partially movable relative to the sensing member 21, and the sensing member 21 senses the moving part of the pressing assembly 1, or the flexible pressing part is arranged on the pressing assembly 1, and the flexible pressing part deforms to press the sensing member 21 when subjected to the pressing force, so that the sensing member 21 senses the pressing force of the pressing assembly 1. For example, a rubber pressing part is arranged on the pressing assembly 1. A person skilled in the art can arrange according to actual needs, which is not limited in the present application.

[0076] As shown in the figures, Figure 2 , Figure 7 and Figure 8 As shown in the figures, in some embodiments of the present application, the car door unlocking device further comprises a light emitting member 5 arranged in the supporting assembly 3, the light emitting member 5 is electrically connected to the circuit board 22, and the circuit board 22 controls the operation of the light emitting member 5.

[0077] In the embodiment of the present application, the circuit board 22 controls the operation of the light-emitting member 5, and the light-emitting member 5 can illuminate the pressing assembly 1 to prompt the user to open the door, so that the user can observe the prompt of the door unlocking, thereby improving the convenience of the door unlocking device.

[0078] In a specific application, the light-emitting member 5 can be at least one of an LED lamp, a light-emitting diode, a laser lamp, a fluorescent lamp, etc., which can be set by those skilled in the art according to actual needs, and the present application does not limit this.

[0079] Specifically, the light-emitting member 5 is electrically connected to the sensing assembly 2, which can be directly welded on the sensing assembly 2 to achieve electrical connection, or the light-emitting member 5 and the sensing assembly 2 can be electrically connected through a wire, which can be set by those skilled in the art according to actual needs, and the present application does not limit this.

[0080] It should be explained that, in actual application, since the material of the supporting assembly 3 is generally a non-light-transmitting material, the light-emitting member 5 will only illuminate the pressing assembly 1 when operating, thereby avoiding the light scattering and insufficient brightness when the light-emitting member 5 operates.

[0081] It can be understood that the circuit board 22 is electrically connected to the sensing member 21, the light-emitting member 5, and the door lock. When the sensing member 21 senses that the pressing assembly 1 is pressed, a pressing signal is sent to the circuit board 22, and the circuit board 22 unlocks the door lock according to the sensing signal, and controls the light-emitting member 5 to operate, and the light-emitting member 5 emits light to illuminate the pressing assembly 1 to prompt the user that the door lock is successfully unlocked.
