Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and in particular to an unlocking device for a vehicle door lock and a vehicle. Background Art

[0002] Vehicles are usually equipped with an automatic locking function. In various news reports on the Internet, we often see that after a vehicle collision, the doors are locked and cannot be opened, which delays the rescue time and even causes the death of the occupants. In the prior art, the door usually relies on electronic signal transmission to achieve the unlocking process. For example, after the body controller detects that the sensor is subjected to a certain acceleration (equivalent to detecting a collision), it will transmit instructions to the electronic lock through an electrical signal, thereby executing the unlocking process, so that the occupants or rescuers can open the door. However, the above-mentioned electrical signal unlocking scheme is unstable. For example, the vehicle collision causes the signal transmission path to be interrupted, the battery is damaged, and the vehicle system may malfunction, etc., and the position setting of the sensor will affect the accuracy of collision recognition. For example, the sensor at the front anti-collision beam cannot detect the collision at the roof A-pillar crossbeam. Utility Model Content

[0024] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but are not intended to limit the present invention.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", all of which may refer to one or more of the same or different embodiments according to the present invention.

[0027] The utility model provides an unlocking device for a vehicle door lock, comprising an elastic member 1, a lever 2, an inertia member 3, and a limiting member 4. The lever 2 is rotatably mounted on the vehicle, and the limiting member 4 is fixedly mounted on the vehicle; the elastic member 1 drives the lever 2 to press the inertia member 3, and the limiting member 4 is limitedly connected with the inertia member 3, so that the lever 2 is in a non-unlocking state; after the inertia member 3 moves away from the limiting member 4, the elastic member 1 drives the lever 2 to rotate to an unlocking state, so as to unlock the vehicle door lock 100.

[0028] Combination Figures 1 to 4 As shown, in the present invention, the Z axis is exemplarily used to represent the vertical direction, the positive direction of the Z axis represents the top, and the negative direction of the Z axis represents the bottom. The X axis represents the longitudinal direction, the positive direction of the X axis represents the front, and the negative direction of the X axis represents the back.

[0029] Combination Figure 1As shown, one end of the elastic member 1 is installed on the vehicle, and the other end of the elastic member 1 is installed on the lever 2. The elastic member 1 has a certain elastic potential energy (it can be in a compressed state or in a stretched state, depending on the installation position of the elastic member 1). Its elastic force makes the lever 2 press-fitted on the inertia member 3 with a certain pre-tightening force. The inertia member 3 is usually an object with large inertia, such as an inertia ball with large mass, an inertia block, etc. The inertia member 3 is pressed by the lever 2 to be limitedly connected with the limit member 4. The limit member 4 can be a baffle, a groove, etc. The lever 2 is structured to achieve a limited connection with the inertia member 3 by abutting, plugging, etc., and the lever 2 is kept in a certain position. At this time, the occupant can still lock and unlock the vehicle door lock 100 according to his or her own needs, or the automatic locking device equipped in the vehicle can control the locking and unlocking of the vehicle door lock 100 (for example, when the vehicle is traveling at high speed, the automatic locking device can control the locking of the vehicle door lock 100 according to information such as the vehicle speed to avoid accidental opening of the door), that is, the lever 2 is in a non-unlocked state, which corresponds to a state where the vehicle has not collided.

[0030] Combination Figure 2 and Figure 3 As shown, they correspond to the states of the unlocking device when the vehicle is rear-ended or frontally collided, for example Figure 2 In the embodiment, the vehicle has an acceleration in the positive direction of the X-axis due to a rear-end collision, and the inertial member 3 has a certain acceleration in the negative direction of the X-axis relative to the vehicle due to its own inertia, so that the inertial member 3 moves away from the limit member 4, and the lever 2 is no longer blocked by the inertial member 3. The elastic potential energy of the elastic member 1 is converted into kinetic energy to make the lever 2 rotate to a certain position, and the lever 2 is connected to the vehicle door lock 100 through a transmission connection, so that the vehicle door lock 100 is unlocked by the lever 2; for example Figure 3 In the embodiment, the vehicle has an acceleration in the reverse direction of the X-axis due to a frontal collision. Due to its own inertia, the inertial member 3 has a certain acceleration in the positive direction of the X-axis relative to the vehicle, so that the inertial member 3 moves away from the limit member 4, and the lever 2 is no longer blocked by the inertial member 3. The elastic potential energy of the elastic member 1 is converted into kinetic energy to make the lever 2 rotate to a certain position. The lever 2 is connected to the vehicle door lock 100 through a transmission, so that the vehicle door lock 100 is unlocked by the lever 2. The lever 2 is in an unlocked state at this time. Regardless of whether the vehicle door lock 100 is locked by the occupant or the automatic locking device before the collision, the lever 2 will unlock the vehicle door lock 100 after the collision, so that the occupant in the vehicle or the person outside the vehicle can open the door according to needs.

[0031] It is understandable that the acceleration threshold required for the inertial member 3 to move away from the limiting member 4 can be obtained through some experimental measurements and other methods, and the mass, material, etc. of the inertial member 3 can be determined according to the acceleration threshold. The specific structure of the inertial member 3 is not limited here. In this embodiment, only the state of the unlocking device when a rear-end collision and a frontal collision occur is shown. In fact, for accidents occurring at various positions that cause a large change in vehicle acceleration, the inertial member 3 can be moved away from the limiting member 4, that is, the unlocking device can unlock the vehicle door lock 100 when various accidents occur. The unlocking of the vehicle door lock 100 described in this specification does not correspond to the state in which the vehicle door is open, but corresponds to the state in which the vehicle door can be opened and closed by the occupants in the vehicle or the personnel outside the vehicle. Accordingly, the locking of the vehicle door lock 100 corresponds to the state in which the vehicle door is forcibly locked and closed, which can prevent the vehicle door from being accidentally opened when the vehicle is driving.

[0032] The unlocking device of the utility model is connected and limited by the limiter 4 and the inertia member 3, and is pressed on the inertia member 3 by the lever 2, so that the lever 2 is in a non-unlocking state. Once the vehicle collides, no matter where the collision occurs, the acceleration of the vehicle will change. The inertia member 3 moves away from the limiter 4 due to its own inertia, and the lever 2 is no longer limited by the inertia member 3 and the limiter 4. The elastic member 1 drives the lever 2 to rotate to the unlocking state, so that the vehicle door lock 100 is unlocked, so that the occupants in the vehicle or the personnel outside the vehicle can open the door by themselves. Compared with the solution of using sensors to detect collision in the traditional technology, the unlocking device of the utility model improves the accuracy of collision detection at different positions; the unlocking device of the utility model adopts a mechanical structure design as a whole, does not rely on electrical signals, and can still unlock the vehicle door lock 100 after a relatively serious collision of the vehicle. After the collision occurs, it is convenient for the occupants in the vehicle to open the door or the rescue personnel outside the vehicle to open the door. It has high reliability, stability and safety, and has lower cost than electronic locks.

[0033] Furthermore, the lever 2 includes a crimping section 21 and an unlocking section 22 , the vehicle door lock 100 is connected to a transmission structure 200 , the unlocking section 22 is used to drive the transmission structure 200 , and the lever 2 is crimped onto the inertia member 3 through the crimping section 21 in the non-unlocked state.

[0034] Combination Figures 1 to 3As shown, the crimping section 21 and the unlocking section 22 are connected to form the lever 2, wherein the unlocking section 22 is connected to the transmission structure 200 to drive the transmission structure 200, and the crimping section 21 is used to be crimped on the inertia member 3, and the inertia member 3 is limited by the limiting member 4, so that the lever 2 as a whole is kept in a non-unlocked state, and after the inertia member 3 is separated from the limiting member 4, the lever 2 is driven by the elastic member 1 to rotate to the unlocked state, so that the unlocking section 22 drives the transmission structure 200, thereby unlocking the vehicle door lock 100.

[0035] It can be understood that the transmission structure 200 can correspond to the transmission part of the mechanical door lock. For example, in the traditional door lock solution, the transmission is realized by structures such as buttons and pull rods. The occupant presses the button to lock the vehicle door lock 100, or pulls out the button to unlock the vehicle door lock 100, so that the occupants in the car or the people outside the car can open and close the door by themselves. Similarly, the electronic door lock is usually transmitted by structures such as motors, gears, and pawls to complete the locking and unlocking of the vehicle door lock 100. The transmission structure 200 in this embodiment can be any one structure or a combination of multiple structures of the above-mentioned transmission parts, as long as the movement of the lever 2 can be transmitted through the transmission structure 200 to realize the unlocking of the vehicle door lock 100.

[0036] In this way, the lever 2 is equivalent to a lever, the inertial member 3 is pressed by the pressing section 21 of the lever 2, and the transmission structure 200 is driven by the unlocking section 22 of the lever 2, which is conducive to the rotation switching of the lever 2 from the non-unlocking state to the unlocking state.

[0037] Furthermore, the lever 2 further includes a connecting section 23 , the crimping section 21 is connected to the unlocking section 22 via the connecting section 23 , and the rotation center of the lever 2 is disposed at the connection between the unlocking section 22 and the connecting section 23 .

[0038] Combination Figures 1 to 3 As shown, the crimping section 21 is integrally connected with the unlocking section 22 through the connecting section 23, and the rotation center of the lever 2 is set between the unlocking section 22 and the connecting section 23, that is, set at the connection between the unlocking section 22 and the connecting section 23. Generally speaking, the crimping section 21 should be set along the horizontal direction (that is, the X-axis direction in the figure) to ensure that the inertial member 3 can move away from the limiting member 4 in all directions. By setting the connecting section 23, when the rotation center of the lever 2 is set at any position, it can be ensured that the crimping section 21 meets the design requirements, for example Figure 1 In the figure, the connecting section 23 and the crimping section 21 are arranged at an angle θ, so that the crimping section 21 can press the inertial member 3 vertically downward (ie, in the opposite direction of the Z axis in the figure) onto the limiting member 4.

[0039] Further, the transmission structure 200 moves forward along the first direction to unlock the vehicle door lock 100, and the transmission structure 200 moves reversely along the first direction to lock the vehicle door lock 100. A connecting groove 201 is provided on the transmission structure 200, and a contact surface 2011 is provided at one end of the connecting groove 201 in the forward direction of the first direction, and an opening 2012 is provided at one end of the connecting groove 201 in the reverse direction of the first direction corresponding to the unlocking section 22. The unlocking section 22 drives the transmission structure 200 by abutting against the contact surface 2011.

[0040] Combination Figures 1 to 3 As shown, the first direction is exemplarily set as the X-axis direction, the transmission structure 200 can move along the positive direction of the X-axis (i.e., the positive direction of the first direction) to unlock the vehicle door lock 100, or move along the reverse direction of the X-axis (i.e., the reverse direction of the first direction) to lock the vehicle door lock 100, and a connecting groove 201 is provided on the transmission structure 200. The connecting groove 201 is an overall U-shaped structure, that is, an opening 2012 is provided at one end, and a contact surface 2011 is provided at the other end, and one end of the opening 2012 faces the opposite direction of the X-axis (i.e., the opposite end of the first direction), and the contact surface 2011 is located at the end of the connecting groove 201 along the positive direction of the X-axis (i.e., the positive end of the first direction). When the lever 2 is rotated and switched from the non-unlocked state to the unlocked state, the transmission structure 200 can be driven by abutting the contact surface 2011. At the same time, in the non-unlocked state, other related devices on the vehicle that control the vehicle door lock 100 can drive the transmission structure 200 (such as an automatic locking device), or the driver can make the transmission structure 200 driven by a structure such as a motor according to his own wishes, thereby achieving the locking or unlocking of the vehicle door lock 100. The opening 2012 can allow the unlocking section 22 of the lever 2 to pass through, so as to avoid affecting the control of the vehicle door lock 100 by other related devices.

[0041] Furthermore, it also includes a support frame 5 fixedly installed on the vehicle, the limit member 4 is fixedly installed in the support frame 5, the elastic member 1 is located in the support frame, one end of the elastic member 1 is connected to the support frame 5, and the other end is connected to the shift rod 2.

[0042] Combination Figures 1 to 3As shown, the support frame 5 is installed on the vehicle, the limiting member 4 is fixedly installed in the support frame 5, the inertia member 3 is crimped to the limiting member 4 by the crimping section 21 of the lever 2 to achieve limiting, and a notch can be set on the support frame 5 for the unlocking section 22 of the lever 2 to extend out to connect with the transmission structure 200. The elastic member 1 is a spring or other elastic component, one end of which is installed on the support frame, and the other end is connected to the positive side of the crimping section 21 along the Z axis. Its elastic force can be applied to the crimping section 21 in the reverse direction of the Z axis in the figure. After the inertia member 3 is separated from the limiting member 4, the elastic force of the elastic member 1 makes the crimping section 21 swing in the opposite direction of the Z axis, thereby driving the lever 2 to rotate clockwise on the plane shown in the figure, and finally driving the transmission structure 200 through the unlocking section 22 to unlock the vehicle door lock 100.

[0043] In this way, the inertia member 3 can be accommodated by the support frame 5 to prevent the inertia member 3 from flying out of the unlocking device after being separated from the limiting member 4, and also provide an installation position for components such as the elastic member 1 and the limiting member 4.

[0044] Furthermore, a groove 41 is provided on the limiting member 4 , and the inertia member 3 is at least partially located in the groove 41 to abut against the limiting member 4 for limiting position.

[0045] Combination Figure 2 and Figure 3 As shown, a groove 41 is provided on the limiting member 4 so that a portion of the inertia member 3 is located in the groove 41 (the inertia member 3 may also be completely located in the groove 41, in which case a portion of the crimping section 21 may also extend into the groove 41 to crimp the inertia member 3), so that the limiting member 4 limits the displacement of the inertia member 3, thereby limiting the rotation of the lever 2, and after the inertia member 3 has a certain acceleration in the horizontal direction, it can move out of the groove 41.

[0046] In this way, the groove 41 can limit the inertial member 3 , and by designing the specific size of the groove 41 , the acceleration threshold required for the inertial member 3 to move away can be affected, thereby adjusting the unlocking sensitivity of the unlocking device.

[0047] Furthermore, the groove 41 is in a conical shape.

[0048] Combination Figure 2 and Figure 3 As shown, the groove 41 is conical in shape, and the inertial member 3 is at least partially located in the groove 41. When the inertial member 3 has a certain acceleration, it will move along the conical inner wall of the groove 41, thereby gradually moving toward the edge of the groove 41 until the acceleration of the inertial member 3 is large enough to move out of the groove 41.

[0049] In this way, the conical groove 41 can provide a certain buffer space for the inertial member 3 to prevent the inertial member 3 from accidentally detaching from the limiting member 4 due to normal driving of the vehicle, and at the same time, the conical inner wall can play a certain limiting role for the inertial member 3.

[0050] Furthermore, the inertial member 3 is spherical in shape.

[0051] Combination Figures 1 to 3 As shown, the inertial member 3 is spherical in shape. When the inertial member 3 has sufficient acceleration, its spherical surface facilitates the movement of the inertial member 3 . For the conical groove 41 , the inertial member 3 will roll along the conical inner wall until it leaves the groove 41 .

[0052] This is conducive to the movement of the inertia member 3 away from the limiting member 4 , thereby preventing the inertia member 3 from getting stuck on the limiting member 4 .

[0053] Furthermore, a driving device 300 is connected to the transmission structure 200 , and the driving device 300 is used to drive the transmission structure 200 .

[0054] Combination Figures 1 to 3 As shown, the drive device 300 can be a traditional mechanical structure, including structures such as buttons, and the occupant can press or pull out the button to drive the transmission structure 200 to unlock or lock the vehicle door lock 100, or the drive device 300 is an electric drive structure, including structures such as motors and gears, and the occupant can control the motor by himself through the central control system, thereby driving the transmission structure 200 to unlock or lock the vehicle door lock 100, and will not be affected by the lever 2. The specific structure of the drive device 300 is not limited here, as long as it can facilitate the occupant to freely control the unlocking and locking of the vehicle door lock 100 in non-emergency situations.

[0055] The utility model also provides a vehicle, combined with Figure 4 As shown, the unlocking device includes the above-mentioned vehicle door lock 100.

[0056] In the vehicle of the utility model, the unlocking device of the vehicle door lock 100 is installed on the vehicle door, for example, the limiter 4 is connected with the inertia member 3 to limit the position, and the lever 2 is pressed on the inertia member 3, so that the lever 2 is in a non-unlocking state. Once the vehicle collides, regardless of the collision position, the acceleration of the vehicle will change, the inertia member 3 moves away from the limiter 4 due to its own inertia, and the lever 2 is no longer limited by the inertia member 3 and the limiter 4. The elastic member 1 drives the lever 2 to rotate to the unlocking state, so that the vehicle door lock 100 is unlocked, so that the occupants or The unlocking device of the utility model improves the accuracy of collision detection at different positions compared with the solution of using sensors to detect collision in the traditional technology; the unlocking device of the utility model adopts a mechanical structure design as a whole, does not rely on electrical signals, and can still unlock the vehicle door lock 100 after a relatively serious collision of the vehicle, which is convenient for the passengers in the vehicle to open the door or the rescue personnel outside the vehicle to open the door after the collision, has high reliability, stability and safety, and has lower cost than electronic locks.
