Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a mechanical door handle structure, a vehicle door and a vehicle. Background Art

[0002] At present, models equipped with hidden mechanical door handles are not associated with Bluetooth keys, and do not have the function of contactless unlocking of the vehicle. Users are required to press the unlock button of the remote control key to disarm the vehicle, and then press one end of the door handle, and wait for the other end to lift up before reaching in to pull the door handle to open the door, resulting in a poor user experience.

[0003] In addition, looking at the models equipped with Bluetooth keys in the market, many models fail to reliably realize the senseless unlocking function through Bluetooth keys, because Bluetooth keys mostly use the change of Bluetooth signal field strength to sense the change of distance, and the sensing accuracy is inaccurate, which affects the user experience. In addition, some high-end models use the fusion solution of Bluetooth keys and UWB digital keys to reliably realize the senseless unlocking function, but the cost is relatively high.

[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0033] First, it should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "longitudinal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a mechanical door handle structure, including: a handle 1, a signal trigger block 2 and a micro switch 3. The signal trigger block 2 is arranged on the handle 1 and is arranged opposite to the micro switch 3; the signal trigger block 2 can change the state of the micro switch 3 under the drive of the handle 1 and send a corresponding signal.

[0036] like Figures 1 to 3 As shown, the handle 1 includes: an outer cover 11 and a handle body 12. The outer cover 11 is mounted on the handle body 12. When the handle 1 is in the retracted state, the handle 1 is located in a groove provided on the outer surface of the door outer panel 9 for accommodating the handle 1. Moreover, the outer cover 11 and the door outer panel 9 form a smooth curved surface, so that the handle 1 in the retracted state presents a visual effect of being hidden in the door outer panel 9. A part of the handle body 12 is located inside the door outer panel 9, and the signal trigger block 2 is arranged on the part of the handle body 12 located inside the door outer panel 9.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, the signal trigger block 2 includes a first guide surface 21 and a second guide surface 22 which are arranged opposite to the micro switch 3, so that when the handle 1 is pulled open, it can drive the signal trigger block 2 to move relative to the micro switch 3, and then the first guide surface 21 and the second guide surface 22 of the signal trigger block 2 are abutted against the micro switch 3, thereby changing the state of the micro switch 3 and causing the micro switch 3 to send a corresponding signal according to its state.

[0038] The micro switch 3 can be a common on-off micro switch or a resistance diagnosis micro switch. Figure 3 When the stowed state in is opened to an angle, for example Figure 6 The position of the micro switch 3 (i.e., the critical angle of the micro switch 3) triggers the state of the micro switch 3 to change. The change can be from the normally open state to the closed state, or from the normally closed state to the open state. Fig.10 As shown, the state of the micro switch 3 remains unchanged. When the handle 1 returns to the critical angle of the micro switch 3, the state of the micro switch 3 jumps back to the initial state until the handle 1 returns to the retracted position, and the state of the micro switch 3 remains in the initial state. In particular, when using a resistor to diagnose the micro switch, the controller can also determine whether there is an abnormality in the micro switch 3 itself, whether there is an abnormality in the wiring harness, etc. through the difference in the resistance value of the micro switch 3, and can display the diagnostic information on the central control screen or record it in the DTC (diagnostic trouble code), which is convenient for quick analysis and processing of after-sales problems.

[0039] like Figure 1 and Figure 2 As shown, the mechanical door handle structure in this embodiment includes a base 6, on which an unlocking block 5 is arranged, and the unlocking block 5 is rotatably connected to the base 6 through a first rotating shaft 61 integrally injection-molded on the base 6. The handle body 12 is rotatably connected to the base 6 through a second rotating shaft 7. A second return spring 8 is arranged on the handle body 12, so as to return to the initial position of the handle body 12 under the action of the restoring force of the second return spring 8 after the handle body 12 is pulled up.

[0040] like Figure 1 and Figure 2 As shown, the mechanical door handle structure in this embodiment also includes a transmission part 4, which is arranged on the handle body 12 and arranged opposite to the unlocking block 5. The transmission part 4 can push the unlocking block 5 to rotate around the first rotating shaft 61 under the drive of the handle body 12 rotating around the second rotating shaft 7, so that the unlocking block 5 pulls the door lock release cable to unlock the door. A guide groove 51 is provided on the unlocking block 5. When the transmission part 4 cooperates with the guide groove 51 of the unlocking block 5, the transmission part 4 can move along the guide groove 51 to push the unlocking block 5 to rotate around the first rotating shaft 61. In addition, a first return spring 10 is also provided on the unlocking block 5, so that after the unlocking block 5 is driven by the transmission part 4 to rotate around the first rotating shaft 61, it returns to the initial position of the unlocking block 5 under the action of the restoring force of the first return spring 10.

[0041] The unlocking process of the vehicle door by the mechanical door handle structure in this embodiment is described in detail below.

[0042] Figure 3 , Figure 6 , Figure 8 and Fig.10 Shown is a schematic diagram of several typical positions of the handle 1 in the mechanical door handle structure in an embodiment of the present application during the opening process.

[0043] The micro switch 3 in this embodiment is of NO type, that is, when the contact of the micro switch 3 is released, the PIN pin of the micro switch 3 is disconnected; when the contact of the micro switch 3 is compressed to the trigger stroke, the PIN pin of the micro switch 3 is turned on.

[0044] Figure 3 Schematic diagram of the handle 1 in the retracted state. At this time, the handle 1 is located in a groove provided on the outer surface of the door outer panel 9 for accommodating the handle 1. The outer cover 11 of the handle 1 and the door outer panel 9 form a smooth curved surface, and the height difference between the surface of the outer cover 11 and the surface of the door outer panel 9 is maintained at -0.5mm, so that the handle 1 in the retracted state presents a visual effect of being hidden in the door outer panel 9. This position is also the initial position of the handle 1. Figure 4 and Figure 5 As shown, in this state, the micro switch 3 and the signal trigger block 2 are in a separated state, no contact occurs, and the micro switch 3 remains in the initial state, that is, when the contact of the micro switch 3 is released, the PIN pin of the micro switch 3 is disconnected. The micro switch 3 and the signal trigger block 2 are in a separated state to avoid possible vibration of the handle 1 during driving, which may cause accidental contact of the micro switch 3 and affect the durability of the micro switch 3.

[0045] like Figure 2 and Figure 6 As shown, when the front end 111 of the outer cover 11 of the handle 1 is pressed, the handle 1 rotates around the second rotation axis 7 under the action of the pressing force, so that the rear end of the handle 1 is tilted and forms a certain angle with the initial position of the handle 1. In this process, the signal trigger block 2 moves toward the micro switch 3 driven by the handle body 12; at the same time, the transmission part 4 moves toward the unlocking block 5 driven by the handle body 12.

[0046] like Figure 6 and Figure 7As shown, when the handle 1 rotates from its initial position around the second rotating shaft 7 until the angle between the handle portion 121 of the handle 1 and the handle portion 121 of the handle 1 in the initial position is 10°, the signal trigger block 2 moves toward the micro switch 3 under the drive of the handle body 12, so that the first guide surface 21 of the signal trigger block 2 compresses the contact of the micro switch 3 to reach the trigger stroke, the state of the micro switch 3 jumps, and the PIN pin of the micro switch 3 jumps from disconnection to conduction. In order to facilitate the contact between the first guide surface 21 and the contact of the micro switch 3, the first guide surface 21 is set as an inclined surface, so that the contact of the micro switch 3 can be smoothly compressed to the trigger stroke during the contact with the first guide surface 21, or smoothly popped out to the initial state. At the same time, the transmission part 4 is further approached to the unlocking block 5 under the drive of the handle body 12. At this time, the space between the handle portion 121 at the rear end of the handle 1 and the door outer panel 9 is not enough for the user to put his hand in.

[0047] like Figure 8 As shown, the front end 111 of the outer cover 11 of the handle 1 is continuously pressed, so that the rear end of the handle 1 continues to tilt up, increasing the angle between the handle 1 and the door outer panel 9. In this process, the signal trigger block 2, driven by the handle body 12, keeps the micro switch 3 in the previous state; at the same time, the transmission part 4, driven by the handle body 12, continues to move toward the unlocking block 5.

[0048] like Fig. 9 As shown, when the handle 1 continues to rotate around the second rotating shaft 7, and the angle between the handle portion 121 of the handle 1 and the handle portion 121 of the handle 1 in the initial position increases from 10° to 25.5°, the signal trigger block 2, driven by the handle body 12, changes from the first guide surface 21 contacting the contact of the micro switch 3 to the second guide surface 22 contacting the contact of the micro switch 3, and moves along the second guide surface 22. During this process, the micro switch 3 always maintains the previous state, that is, the PIN pin of the micro switch 3 is turned on. The second guide surface 22 can be set to a plane, so that during the period when the micro switch 3 moves on the second guide surface 22, the state of the micro switch 3 is stably maintained in the triggered state.

[0049] Meanwhile, in this process, the transmission part 4 is driven by the handle body 12 to approach the guide groove 51 of the unlocking block 5. When the handle 1 is rotated to the position of 25.5° as described above, the transmission part 4 moves into the guide groove 51 of the unlocking block 5 and abuts against the unlocking block 5. Moreover, when the handle 1 is in this position, there is enough space between the handle part 121 and the door outer panel 9 for the user to put his hand in and hold the handle part 121.

[0050] During the process of opening the handle 1 from the initial position to the 25.5° position as described above, the transmission part 4 and the unlocking block 5 have not been in contact, and the main resistance overcome by the handle 1 is the restoring force of the second return spring 8, which makes it convenient for the user to press the front end 111 of the handle 1 with less effort to make the rear end of the handle 1 tilt up, so as to obtain enough space for the hand to reach between the handle part 121 of the handle 1 and the door outer panel 9.

[0051] The transmission part 4 moves to the guide groove 51 of the unlocking block 5 and contacts the unlocking block 5; and slides along the guide groove 51 of the unlocking block 5, thereby pushing the unlocking block 5 to rotate around the first rotating shaft 61. Then, the door lock release cable is pulled by the unlocking block 5 to perform the unlocking operation. When the handle 1 is rotated to the position of 25.5° as described above, there is enough space between the handle part 121 and the door outer panel 9 for the user to reach in and hold the handle part 121. When the vehicle is in the state of disengaging the insurance, the user reaches out and holds the handle part 121 of the handle 1, and continues to pull the handle 1 outward to open the door.

[0052] like Fig.10 and Fig.11 As shown, after the user holds the handle portion 121 of the handle 1, the handle 1 continues to be pulled outward, so that the transmission part 4 slides along the guide groove 51 of the unlocking block 5 driven by the handle body 12, and pushes the unlocking block 5 to rotate around the first rotating shaft 61. Then, the door lock release cable is pulled by the unlocking block 5 to perform the unlocking operation. When the vehicle is released from insurance, the door can be opened. In this process, the signal trigger block 2 is driven by the handle body 12, and the second guide surface 22 contacts the contact of the micro switch 3, and the third guide surface 23 contacts the contact of the micro switch 3. In addition, the third guide surface 23 is set to be an inclined surface with a set angle with the second guide surface 22, so that when the handle body 12 drives the transmission part 4 to push the unlocking block 5 to rotate, the third guide surface 23 also slides over the micro switch 3, and in the process of the contact of the micro switch 3 moving along the third guide surface 23, the micro switch 3 always remains in a triggered state, and the PIN pin of the micro switch 3 is always in conduction.

[0053] After unlocking the door, the user releases the grip on the handle 1. Under the action of the second return spring 8, the handle 1 returns from the open position to the initial position of the initial retracted state; at the same time, the unlocking block 5 also begins to rotate toward its initial position under the action of the restoring force of the first return spring 10. Because the rotation angle range of the handle 1 is larger than the rotation angle range of the unlocking block 5, after the unlocking block 5 returns to its initial position first, the handle 1 needs to rotate a certain angle to return to its initial position. In this process, the handle body 12 drives the signal trigger block 2 back to its original position under the action of the restoring force of the second return spring 8. Figure 4 The initial position shown is separated from the micro switch 3; and the transmission part 4 is separated from the unlocking block 5 and returns to the initial position. Figure 4 After the unlocking block 5 is separated from the transmission part 4, it returns to the initial position under the action of the restoring force of the first return spring 10. Figure 4 Initial position shown.

[0054] An embodiment of the present application also provides a vehicle door, which includes the mechanical door handle structure as described above.

[0055] An embodiment of the present application further provides a vehicle, which includes a door as described above and a control device, wherein the control device is used to receive a signal sent by a micro switch 3 in a mechanical door handle structure, and realizes contactless unlocking of the door by cooperating with a Bluetooth key.

[0056] Specifically, when a user brings a Bluetooth key close to a vehicle, after the Bluetooth key is within a set range from the vehicle, the Bluetooth key and a control device, such as a body controller (BCM, Body Control Module), establish communication to complete the user's identity authentication.

[0057] When the user continues to approach the car door and pulls the handle 1, and opens the handle 1 to 10° as described above, the micro switch 3 jumps from the release state to the trigger state, and the PIN foot of the micro switch 3 is turned on, so that the circuit connected between the micro switch 3 and the BCM is turned on. Then the BCM and the Bluetooth key quickly complete the verification and release the insurance of the vehicle. So that when the user then puts his hand between the handle portion 121 of the handle 1 and the outer panel 9 of the car door, holds the handle portion 121 and continues to pull it outward, the door can be unlocked and opened. The whole process moves smoothly, and unlocking and opening the door can be achieved without deliberate pauses and unnecessary operations. Since the Bluetooth key approaches and establishes communication with the vehicle controller for identity authentication, which is a very mature technology on the market, and the micro switch technology itself is also very mature and has high reliability, the non-sensing unlocking solution can obtain high reliability and realize a truly low-cost, high-reliability non-sensing unlocking function.

[0058] By means of the first guide surface 21 and the second guide surface 22 provided on the signal trigger block 2, when the handle 1 is opened from the initial position to the 10° position, the first guide surface 21 begins to contact the micro switch 3, causing the state of the micro switch 3 to jump from disconnection to conduction, and making the circuit connecting the micro switch 3 and the BCM conduction. Based on this, the BCM determines that the handle 1 is pulled to open the door. In the process of the handle 1 opening from the 10° position to the 25.5° position, the BCM performs logical judgment and data processing; and after completing the logical judgment and data processing, the vehicle is released at a certain position in the process of the handle 1 opening from the 10° position to the 25.5° position.

[0059] In the process of opening the handle 1 from the 10° position to the 25.5° position, the first guide surface 21 and the second guide surface 22 are always in contact with the micro switch 3, so that the micro switch 3 is always in the on state, so that the circuit connecting the micro switch 3 and the BCM is always on. The BCM judges that the micro switch 3 is always in the on state, thereby reserving enough time for the BCM to perform logical judgment and data processing, and release the vehicle insurance, so that the user can open the door after continuing to pull the handle 1 from the 25.5° position to unlock the door. In this way, the user can complete the operation of releasing the vehicle insurance and unlocking the door, and open the door in the process of pulling the handle 2 once, so that the user can experience the unlocking without feeling.

[0060] Because disarming the vehicle is a prerequisite for unlocking the door lock, by providing the first guide surface 21 and the second guide surface 22 on the signal trigger block 2, it is avoided that the BCM does not have enough time to make logical judgments, so that when the user pulls the handle 1 to open the door, the BCM fails to disarm the vehicle in time, resulting in the user being unable to open the door when the handle 1 is opened to the full open position.

[0061] In addition, by setting a third guide surface 23 on the signal trigger block 2, the BCM is further given a longer time to perform logical judgment and data processing, so that even in some extreme cases, for example, when the user pulls the handle 1 very quickly during the door opening process, resulting in the BCM still not releasing the vehicle insurance when the micro switch 3 relatively slides over the first guide surface 21 and the second guide surface 22 on the signal trigger block 2; through the abutment between the third guide surface 23 and the micro switch 3, the BCM can release the vehicle insurance before the handle 1 is opened to the maximum extent, so that the user can unlock the door and open it smoothly, thereby improving the reliability of the senseless unlocking.

[0062] Furthermore, by setting the third guide surface 23 as an inclined surface forming a set angle with the second guide surface 22, rather than simply extending the second guide surface 22 in the direction of the XZ plane of the vehicle coordinate system, it is possible to reduce the space occupied by the signal trigger block 2 in the Y-axis direction of the vehicle coordinate system, reduce the thickness of the door in the Y-axis direction of the vehicle coordinate system, and avoid interference between the signal trigger block 2 and the window glass located close to the XZ plane of the vehicle coordinate system during the rotation of the handle 1.

[0063] When the user opens the door, the BCM can accurately detect the jump of the micro switch 3 signal. Therefore, through the reasonable selection of the micro switch 3 and the reasonable design of the matching structure with the handle 1, the durability of the micro switch 3 and the reliability of the BCM detecting the jump of the micro switch 3 signal are ensured.

[0064] In addition, the technology of establishing communication with BCM to complete identity authentication when the user carries the Bluetooth key close to the vehicle is mature and reliable, and is designed to cause the signal trigger block 2 to trigger the state change of the micro switch 3 when the user presses the front end of the handle 1, thereby triggering the BCM and the Bluetooth key to complete the verification and release the vehicle insurance in a very short time, which can ensure that the vehicle insurance is released before the person's hand reaches into the rear end of the handle 1 to continue to open the handle 1, thereby ensuring that the person's hand reaches into the rear end of the handle 1 to grasp the handle part 121 and continue to open the handle 1 to open the vehicle door.

[0065] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
