Description

Technical Field

[0001] This application relates to the field of handle control technology, and more particularly to a vehicle exterior door handle and a vehicle. Background Technology

[0002] As vehicles become more widely used, users are also placing higher demands on the design of vehicle exterior door handles.

[0003] Traditional vehicle exterior door handles are designed to unlock the door by pressing a microswitch (located on the inside of the handle facing the door). This design has certain drawbacks, as the door can only be unlocked via the microswitch. This means that the functionality of the vehicle exterior door handle is limited because it can only be unlocked via the microswitch. Utility Model Content

[0004] The main purpose of this application is to provide a vehicle exterior door handle and a vehicle, aiming to solve the technical problem of low functionality of vehicle exterior door handles.

[0005] To achieve the above objectives, this application provides a vehicle exterior door handle, which includes an external sensing unit located at a sensing position on the outer side of the vehicle exterior door handle, an internal button located at a button position on the inner side of the vehicle exterior door handle, and a two-section opening unit located inside the vehicle exterior door handle.

[0006] The output of the external sensing unit is connected to the door controller, the output of the internal button is connected to the door controller, and the output of the two-stage opening unit is connected to the door controller. The door controller is used to control the door to unlock based on the signals from the external sensing unit, the internal button, or the two-stage opening unit.

[0007] In one embodiment, the external sensing unit includes:

[0008] A pressure sensor is disposed at the sensing position, and the output terminal of the pressure sensor is connected to the door controller;

[0009] A capacitive sensor is disposed at the sensing position, and the output terminal of the capacitive sensor is connected to the door controller.

[0010] In one embodiment, the external sensing unit further includes:

[0011] An AND gate device is provided, wherein the first input terminal of the AND gate device is connected to the output terminal of the pressure sensor, the second input terminal of the AND gate device is connected to the output terminal of the capacitive sensor, and the output terminal of the AND gate device is connected to the door controller, and the door controller is used to control the door unlocking based on the output signal of the AND gate device.

[0012] In one embodiment, the internal button includes:

[0013] A micro switch is disposed at the button position. The output terminal of the micro switch is connected to the door controller. The micro switch is configured to output a first signal at its input terminal when the micro switch is not pressed, and to output a second signal at its input terminal when the micro switch is pressed. The first signal and the second signal are different. The door controller is used to control the door to unlock based on the second signal.

[0014] In one embodiment, the two-segment opening unit includes:

[0015] A contact switch is connected to the door controller, and the contact switch is configured to output a signal when triggered so that the door controller controls the door to unlock.

[0016] A door opening mechanism is provided, which is disposed between the contact switch and the door opening rod and is throttle connected to the contact switch and the door opening rod. When the door opening rod is pulled, the door opening mechanism rotates to trigger the contact switch. The door controller is used to control the door to unlock based on the signal from the contact switch.

[0017] In one embodiment, the two-segment opening unit includes:

[0018] A first limiting structure is disposed on the door opening transmission mechanism and rotates synchronously with the door opening transmission mechanism. The first limiting structure is mechanically connected to the contact switch. When the door opening rod is pulled, the first limiting structure is driven to a first state. In the first state, the first limiting structure presses down the spring of the contact switch so that the contact of the contact switch contacts with the spring to complete the triggering.

[0019] In one embodiment, a first damping element is provided in the door opening transmission mechanism. When the door opening lever is pulled, the first damping element abuts against the door opening transmission mechanism and is configured to always provide resistance opposite to the rotation direction of the door opening transmission mechanism.

[0020] The two-segment opening unit includes:

[0021] Second damping element;

[0022] The second limiting structure is disposed on the door opening transmission mechanism and rotates synchronously with the door opening transmission mechanism. The second limiting structure is configured such that when the door opening rod is pulled to a preset position, the second damping element contacts the second limiting structure and provides resistance to the rotation of the door opening transmission mechanism.

[0023] In one embodiment, after the door controller unlocks the door based on signals from the external sensing unit, the internal button, or the two-stage opening unit, it opens the door to a preset angle under motor drive or under external pulling force.

[0024] In one embodiment, the two-segment opening unit further includes:

[0025] A pull-wire driven structure is mounted on the door opening transmission mechanism and rotates synchronously with the door opening transmission mechanism;

[0026] A car lock cable, wherein the first end of the car lock cable is connected to the car door lock, and the second end of the car lock cable is connected to the cable drive structure. The cable drive structure is configured to stretch the car lock cable when it rotates synchronously with the door opening transmission mechanism.

[0027] The door opening transmission mechanism is further configured such that when the door opening rod is pulled, it drives the second damping element to rotate to a second state, so that in the second state, the pull cable drive structure drives the door lock cable to open the door lock, thereby unlocking the door.

[0028] In one embodiment, the door opening mechanism includes:

[0029] Drive shaft;

[0030] A rotating component, the central axis of which passes through the transmission central shaft, is connected to the door opening rod in a transmission manner. The rotating component is provided with a pull cable drive structure, a first limiting structure, and a second limiting structure. The rotating component is configured to drive the pull cable drive structure, the first limiting structure, and the second limiting structure to rotate synchronously when the door opening rod is pulled.

[0031] In addition, to achieve the above objectives, this application also provides a vehicle that includes the aforementioned vehicle exterior door handle.

[0032] In one embodiment, the vehicle includes a door controller, a door lock, and a door electric drive structure. The door controller is electrically and / or signal-connected to the vehicle's exterior door handle, the door lock, and the door electric drive structure. The motor in the door electric drive structure is used to control the electric opening of the door.

[0033] This application provides a vehicle exterior door handle, which includes an external sensing unit located at a sensing position on the outer side of the handle, an internal button located at a button position on the inner side of the handle, and a two-stage opening unit located inside the handle. The output of the external sensing unit is connected to a door controller, as are the outputs of the internal button and the two-stage opening units. The door controller controls door unlocking based on signals from the external sensing unit, the internal button, or the two-stage opening units. This vehicle exterior door handle, by simultaneously connecting the external sensing unit at the sensing position on the outer side of the handle, the internal button at the button position on the inner side of the handle, and the two-stage opening units inside the handle, allows the door controller to control door unlocking based on signals from these components. This avoids the limitation of unlocking only via a manual microswitch, improving the functionality of the vehicle exterior door handle by controlling door unlocking through signals from these components.

[0048] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0049] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0050] With the rapid development of intelligent electric doors in the automotive industry, and considering the increasing demand for convenience and diversity in door opening methods across various usage scenarios, the industry is no longer limited to a single, fixed method. Traditional electric side-opening doors have two main approaches: one uses a button for opening, but the button switch requires a specific design, resulting in a gap in the handle and affecting its aesthetics. Furthermore, the button switch requires a certain pressing distance to trigger the switch, and prolonged pressing can damage the button or mechanism, increasing the risk of failure. Another approach uses a microswitch in the handle for electric release to unlock the door. However, these handles are generally fixed and cannot be mechanically pulled. Due to regulations limiting outward protrusion and the limited internal grip space, the button is often placed too low. This means that when the hand grips the handle to pull the door, the button may be in a hollow position, failing to trigger the microswitch and thus preventing unlocking.

[0051] Therefore, based on the shortcomings of the above-mentioned vehicle exterior door handles, the vehicle exterior door handle of this application is proposed. The main solution of the embodiments of this application is: by connecting the external sensing unit at the sensing position on the outer side of the vehicle exterior door handle, the internal button at the button position on the inner side of the vehicle exterior door handle, and the two-stage opening unit inside the vehicle exterior door handle, the external sensing unit, the internal button, and the two-stage opening unit are all connected to the door controller. The door controller can control the door to unlock based on the signals of the external sensing unit, the internal button, or the two-stage opening unit, thereby avoiding the phenomenon that unlocking can only be achieved by a manual micro switch. That is, the door unlocking is controlled by the signals of the external sensing unit, the internal button, or the two-stage opening unit, thereby improving the functionality of the vehicle exterior door handle.

[0052] Based on this, this application provides a vehicle exterior door handle, referring to... Figure 1 , Figure 1 This is a schematic diagram of a frame of the first embodiment of the vehicle exterior door handle of this application.

[0053] Reference Figure 1 This application provides a vehicle exterior door handle 100, which includes an external sensing unit 10 located at a sensing position on the outer side 110 of the vehicle exterior door handle 100, an internal button 20 located at a button position on the inner side 120 of the vehicle exterior door handle 100, and a two-stage opening unit 30 located inside the vehicle exterior door handle 100.

[0054] The output of the external sensing unit 10 is connected to the door controller 200, the output of the internal button 20 is connected to the door controller 200, and the output of the two-stage opening unit 30 is connected to the door controller 200. The door controller 200 is used to control the door to unlock based on the signals from the external sensing unit 10, the internal button 20, or the two-stage opening unit 30.

[0055] In this embodiment, the vehicle exterior door handle 100 includes an external sensing unit 10 located at a sensing position on the outer side 110 of the vehicle exterior door handle 100, an internal button 20 located at a button position on the inner side 120 of the vehicle exterior door handle 100, and two opening units 30 located inside the vehicle exterior door handle 100. It is worth noting that the location of each unit on the outer side 110 or the inner side 120 of the vehicle exterior door handle 100 means that at least one component of the unit can be observed on either the outer side 110 or the inner side 120 of the vehicle exterior door handle 100, while other components of the unit, such as communication lines, are still located inside the vehicle exterior door handle 100. Furthermore, the sensing position and button position can be set according to user needs or actual design requirements. For example, if a user presses the button with their index finger, the button position can be set at the index finger pressing position on the inner side 120 of the vehicle exterior door handle 100. Of course, it can also be set in other positions, which is not limited here. For example, by designing an external sensing unit 10, an internal button 20, and a two-stage opening unit 30 on the vehicle's exterior door handle 100, and connecting the external sensing unit 10, internal button 20, and two-stage opening unit 30 to the door controller 200 respectively, the door controller 200 will control the door to unlock after receiving a signal from the external sensing unit 10, internal button 20, or two-stage opening unit 30, and then perform electric opening based on subsequent pulling force or directly. The signals from the external sensing unit 10, internal button 20, or two-stage opening unit 30 can be common high and low level signals, or other custom opening signals. In this case, the vehicle's exterior door handle 100 can control the door to unlock based on the signals from the external sensing unit 10, internal button 20, or two-stage opening unit 30, thereby expanding the unlocking functionality of the vehicle's exterior door handle 100.

[0056] In one embodiment, reference may be made to Figure 2 , Figure 2This is another schematic diagram of the framework of the first embodiment of the vehicle exterior door handle of this application. The external sensing unit 10 can be a sensing area disposed on the outer side 110 of the vehicle exterior door handle 100. After sensing the user's door opening request, the sensing area will send an unlocking signal to the door controller 200, so that the door controller 200 controls the door to unlock. The sensing area can sense the user's door opening request by the user placing their finger on the sensing position and generating pressure. For example, the internal button 20 can generate a corresponding unlocking signal after the user presses the button in the internal button 20, thereby controlling the door to unlock. For example, the two-stage opening unit 30 can unlock the door directly based on the pulling force signal by the user pulling the door. Therefore, the control hardware for the above three door opening methods can be designed on the vehicle exterior door handle 100, thereby realizing at least the above three unlocking methods and expanding the functionality of the vehicle exterior door handle 100 in controlling unlocking.

[0057] In this embodiment, a vehicle exterior door handle 100 is provided. The vehicle exterior door handle 100 includes an external sensing unit 10 located at a sensing position on the outer side 110 of the vehicle exterior door handle 100, an internal button 20 located at a button position on the inner side 120 of the vehicle exterior door handle 100, and a two-stage opening unit 30 located inside the vehicle exterior door handle 100. The output terminal of the external sensing unit 10 is connected to a door controller 200, the output terminal of the internal button 20 is connected to the door controller 200, and the output terminal of the two-stage opening unit 30 is connected to the door controller 200. The door controller 200 is used to control the door unlocking based on signals from the external sensing unit 10, the internal button 20, or the two-stage opening unit 30. By connecting the external sensing unit 10 at the sensing position on the outer side 110 of the vehicle's outer door handle 100, the internal button 20 at the button position on the inner side 120 of the vehicle's outer door handle 100, and the two-stage opening unit 30 inside the vehicle's outer door handle 100, and simultaneously connecting the external sensing unit 10, the internal button 20, and the two-stage opening unit 30 to the door controller 200, the door controller 200 can control the door to unlock based on the signals from the external sensing unit 10, the internal button 20, or the two-stage opening unit 30. This avoids the phenomenon that unlocking can only be achieved through a manual micro-switch, that is, controlling the door to unlock through the signals from the external sensing unit 10, the internal button 20, or the two-stage opening unit 30, thereby improving the functionality of the vehicle's outer door handle 100.

[0058] Furthermore, based on the first embodiment of this application described above, a second embodiment of the vehicle exterior door handle of this application is proposed, referring to... Figure 3 , Figure 3 This is a connection diagram of the second embodiment of the vehicle exterior door handle of this application. The external sensing unit 10 includes:

[0059] Pressure sensor 11 is set at the sensing position, and the output end of pressure sensor 11 is connected to door controller 200.

[0060] Capacitive sensor 12 is set at the sensing position, and the output terminal of capacitive sensor 12 is connected to door controller 100.

[0061] Furthermore, the external sensing unit 10 also includes:

[0062] An AND gate device is used. The first input terminal of the AND gate device is connected to the output terminal of the pressure sensor 11, the second input terminal of the AND gate device is connected to the output terminal of the capacitive sensor 11, and the output terminal of the AND gate device is connected to the door controller 200. The door controller 200 is used to control the door unlocking based on the output signal of the AND gate device.

[0063] In this embodiment, the external sensing unit 10 includes a pressure sensor 11 and a capacitance sensor 12. Both sensors are located at the sensing position, such as the area pressed by the user's thumb when opening the door. The sensing position can then identify the pressure signal and capacitance changes at the sensing position and send the identified signals to the processor 210 in the door controller 200. The processor 210 analyzes whether the pressure signal and capacitance signal meet the set conditions. If both the pressure signal and capacitance signal simultaneously meet the set conditions, the processor 210 sends a signal to the domain controller 220 in the door controller 200. The domain controller 220 sends an unlock signal to the door lock 300 and an open signal to the door electric drive structure 400. Based on the door lock 300, an unlock command is executed, and the door electric drive structure 400 executes an open command, achieving electric unlocking and opening. In other words, the door controller 200 can control the door to unlock based on the signals from the pressure sensor 11 and the capacitance sensor 12, and then open the door to a preset angle under motor drive, thus achieving unlocking and electric opening. For example, the door controller 200 is merely a general term for a single controller, a collection of all controls for opening the door; its internal components will not be described individually here. For example, the processor 210's function is to determine whether the pressure and capacitance signals meet set conditions. These set conditions refer to the user's door-opening requirements. If the pressure sensor 11 outputs a high level when subjected to pressure, and the capacitance sensor 12 outputs a high level when the capacitance value changes, then the set conditions defined in the processor 210 mean that both sensors output a high level. An AND gate device can be used to process the output, and the domain controller 220 is defined to execute the unlocking and opening operation when it receives a high level. Therefore, the domain controller 220 will only execute the unlocking and opening operation when both sensors output a high level. For example, the door electric drive structure 400 can be directly a device that drives the door to move, such as a motor that drives the door to open. When the door needs to be opened, power is supplied to the motor, thereby achieving electric door opening.

[0064] In one embodiment, the pressure sensor 11 and the capacitance sensor 12 are used to prevent accidental touches when identifying user needs. For example, if an external object presses the sensing position but the data collected by the capacitance sensor does not change, it can be determined that there is no unlocking need. This can be achieved if a stone is fired at the sensing position. Similarly, if an external object causes a change in capacitance but the data collected by the pressure sensor does not change, it can be determined that there is no unlocking need. This can also be achieved if rainwater passes over or touches the sensing position. Therefore, the pressure sensor 11 and the capacitance sensor 12 can be combined to ensure the accuracy of identifying user unlocking needs.

[0065] In one embodiment, based on the first and / or second embodiments of this application described above, a third embodiment of the vehicle exterior door handle of this application is proposed, referring to... Figure 4 , Figure 4 This is a schematic diagram of the framework of the third embodiment of the vehicle exterior door handle of this application. The internal button 20 includes:

[0066] Microswitch 21 is located at the button position. The output of microswitch 21 is connected to door controller 200. Microswitch 21 is configured to output a first signal at its input when it is not pressed, and to output a second signal at its input when it is pressed. The first signal and the second signal are different. Door controller 200 is used to control door unlocking based on the second signal.

[0067] In this embodiment, the internal button 20 includes a micro switch 21. The micro switch 21 is configured to output a first signal at its input terminal when it is not pressed, and to output a second signal at its input terminal when it is pressed. The first signal and the second signal are different, so that the door controller 200 controls the door to unlock based on different signals, such as the first signal and the second signal being high and low level signals, respectively. For example, after the vehicle's central locking system is unlocked, if the micro switch 21 in the internal button 20 is pressed, the vehicle controller recognizes the signal of the micro switch 21 (assuming the first signal is the pressed signal), and controls the door lock 300 to automatically release and hold for a certain period of time. At the same time, the vehicle controller controls the door controller 200 to not supply power to the electric drive, so the user can hold the vehicle's outer door handle 100 and pull the door to the required opening degree. That is, after the user unlocks the door, the door opens to a preset angle under external pulling force (provided by the user). Of course, there is also a control method, that is, after the door is unlocked based on the second signal, the door opens to a preset angle under the drive of the motor. That is, after the user directly presses the micro switch 21 to upload the second signal, the door is directly unlocked and opened electrically. Thus, the micro switch 21 can be used to control the door unlocking based on the above control.

[0068] Based on the first, second, and / or third embodiments of the vehicle exterior door handle described above, a fourth embodiment of the vehicle exterior door handle of this application is proposed, with reference to... Figure 5 , Figure 5 This is a schematic diagram of a frame of the fourth embodiment of the vehicle exterior door handle of this application. The two opening units 30 include:

[0069] Contact switch 31 is connected to the door controller. When the contact switch 31 is triggered, it outputs a signal to enable the door controller to unlock the door.

[0070] The door opening mechanism 32 is disposed between the contact switch 31 and the door opening rod 130, and is connected to the contact switch 31 and the door opening rod 130 in a transmission manner. When the door opening rod 130 is pulled, the door opening mechanism 32 rotates to trigger the contact switch 31. The door controller is used to control the door unlocking based on the signal from the contact switch 31.

[0071] Furthermore, the two-stage opening unit 30 includes:

[0072] The first limiting structure 33 is mounted on the door opening transmission mechanism 32 and rotates synchronously with the door opening transmission mechanism 32. The first limiting structure 33 is mechanically connected to the contact switch 31. When the door opening rod 130 is pulled, the first limiting structure 33 is driven to the first state. In the first state, the first limiting structure 33 presses down the spring 312 of the contact switch 31 so that the contact 311 of the contact switch 31 contacts the spring 312 to complete the triggering.

[0073] In this embodiment, to avoid the inability to directly press the micro switch 21, a two-stage opening unit 30 can be provided. Thus, when the micro switch 21 is not triggered, pulling the handle forcefully (70-80N) will open the vehicle's exterior door handle 100 to the first open position, triggering the contact switch 31, allowing the door to be electrically released or manually opened. That is... Figure 5 According to the description, the user can directly pull the door handle 100 to the door opening lever 130 at the first distance value, which will trigger the contact switch 31. When the contact switch 31 is set to trigger, it outputs a signal to cause the door controller 200 to control the door to unlock. At this time, unlocking can be achieved by simply unlocking and allowing the user to open the door manually, or by directly unlocking and allowing the door to open electrically. However, the electric door opening method is generally not used because the user cannot accurately know the first distance value that needs to be triggered to unlock. For example, refer to Figure 6 , Figure 6This is a structural schematic diagram of the fourth embodiment of the vehicle exterior door handle of this application. The two-section opening unit 30 also includes an opening transmission mechanism 32 (not shown in the figure). The opening transmission mechanism 32 is disposed between the contact switch 31 and the door opening rod 130, and is connected to the contact switch 31 and the door opening rod 130 in a transmission manner (i.e., the connection method of driving the other when moving). The entire opening transmission mechanism 32 is configured to drive the opening transmission mechanism 32 to rotate around the transmission central shaft 322 when the door opening rod 130 is pulled, so as to trigger the contact switch 31 when rotating to the first state. The door controller 200 is used to control the door unlocking based on the signal of the contact switch 31. It is worth noting that the door opening transmission mechanism 32 can be a mechanical structure as shown in the figure. When the door opening lever 130 is pulled, it moves together with the door opening lever 130, thereby triggering the contact switch 31. At this time, the contact switch 31 can generate a signal to inform the door controller 200 that unlocking control is required. If a position sensor is directly installed at the contact switch 31, the contact switch 31 will generate a signal for control when it is in the triggered state. Alternatively, current can be used for control. For example, when the contact 311 and the spring 312 of the contact switch 31 are connected, the entire circuit is conductive and current is generated, and control is performed based on the conductive signal. Conversely, when the contact 311 and the spring 312 of the contact switch 31 are not connected, it is equivalent to no signal being output.

[0074] In one feasible embodiment, reference may be made to Figure 7 , Figure 7 This is an initial structural diagram of the fourth embodiment of the vehicle exterior door handle of this application. At this time, the door opening lever 130 is not pulled, meaning that the contacts 311 and spring 312 of the contact switch 31 (contacts 311 and spring 312 are not in contact when the contact switch 31 is in its initial position), and the door opening transmission mechanism 32 are all in their initial positions. The information transmitted by the communication device 313 is "Do not control door unlocking." Then, as the door opening lever 130 is pulled, referring to... Figure 8 , Figure 8This is a schematic diagram of the end structure of the fourth embodiment of the vehicle exterior door handle of this application. A first limiting structure 33 can also be designed in the two-section opening unit. The first limiting structure 33 is set on the door opening transmission mechanism 32 and rotates synchronously with the door opening transmission mechanism 32. The first limiting structure 33 is connected to the contact switch 31 (mainly in contact with the spring 312). When the door opening rod 130 is pulled, it drives the door opening transmission mechanism 32 to rotate, and then, based on the rotation of the door opening transmission mechanism 32, it drives the first limiting structure 33. The first limiting structure 33 then... When the door is rotated to the first state, the first limiting structure 33 presses down the spring 312 of the contact switch 31, so that the contact 311 of the contact switch 31 contacts the spring 312 to complete the triggering. At this time, the information transmitted by the communication device 313 is to control the door to unlock. The door can be unlocked by triggering the contact switch 31 through the first limiting structure 33 on the door opening transmission mechanism 32, so as to avoid the phenomenon that the micro switch 21 cannot be pressed directly, thereby expanding the functionality of the vehicle exterior door handle 100 to control the door unlocking.

[0075] In one embodiment, reference is made to Figure 9 , Figure 9 This is another schematic diagram of the frame of the fourth embodiment of the vehicle exterior door handle of this application. A first damping element 321 is provided in the door opening transmission mechanism 32. When the door opening rod 130 is pulled, the first damping element 321 abuts against the door opening transmission mechanism 32 and is set to always provide resistance opposite to the rotation direction of the door opening transmission mechanism 32.

[0076] The two-stage opening unit 30 includes:

[0077] The second damping element 341 (can be set in a damping structure 34, which can be cylindrical, whistle-shaped, etc.);

[0078] The second limiting structure 35 is disposed on the door opening transmission mechanism 32 and rotates synchronously with the door opening transmission mechanism 32. The second limiting structure 35 is configured such that when the door opening rod 130 is pulled to a preset position, the second damping element 341 contacts the second limiting structure 35 and provides resistance to the rotation of the door opening transmission mechanism 32.

[0079] Furthermore, the two-stage opening unit 30 also includes:

[0080] The pull wire drives the structure 36, which is mounted on the door opening transmission mechanism 32 and rotates synchronously with the door opening transmission mechanism 32.

[0081] The car lock cable 37 has its first end connected to the car door lock 300 and its second end connected to the cable drive structure 36. The cable drive structure 36 is configured to stretch the car lock cable 37 when it rotates synchronously with the door opening transmission mechanism 32.

[0082] The door opening transmission mechanism 32 is also configured to drive the second damping element 341 to rotate to the second state when the door opening rod 130 is pulled, so that in the second state the pull cable drive structure 36 drives the door lock pull cable 37 to pull the door lock 300, thereby unlocking the door.

[0083] In this embodiment, the two-stage opening unit 30 includes a second damping element 341 and a second limiting structure 35. The second limiting structure 35 is disposed on the door opening transmission mechanism 32 and rotates synchronously with the door opening transmission mechanism 32. The second limiting structure 35 is configured such that when the door opening lever 130 is pulled, the second damping element 341 contacts the second limiting structure 35 and provides resistance to the rotation of the door opening transmission mechanism 32. At this time, because it is necessary to drive the second damping element 341 to rotate, a greater force is required to pull the door. It is worth noting that the second damping element 341 can initially contact the second limiting structure 35. If a spring is provided in the second damping element 341, the greater the distance the door is pulled, the greater the force required. Alternatively, the second limiting structure 35 can contact the second damping element 341 after the door opening transmission mechanism 32 has driven the first limiting structure 33 to the first state, so that a greater force is required to pull the door after this point. Furthermore, the two-stage opening unit 30 also includes a vehicle lock cable 37 and a cable-driven structure 36. The first end of the vehicle lock cable 37 is connected to the door lock 300, and the second end is connected to a cable position 361 on the cable-driven structure 36. The cable position 361 is configured such that when the door opening transmission mechanism 32 rotates, the cable-driven structure 36 rotates synchronously to stretch the vehicle lock cable 37, thereby achieving mechanical unlocking of the vehicle lock cable 37. When a power outage or collision fault is detected, mechanical door opening control is executed. That is, when mechanical unlocking of the door is required, the outer handle is pulled (>120N) from its initial position (the second state position of the first limit structure 33) to the open position by gripping the outer handle. During the pulling process, the vehicle lock cable 37 connected to the door lock 300 is activated, and the vehicle lock cable 37 unlocks the door lock 300. Then, by gripping the outer handle, the door can be opened to the desired degree. For example, refer to... Figure 10 , Figure 10 This is another initial structural schematic diagram of the fourth embodiment of the vehicle exterior door handle of this application. At this time, the door opening lever 130 is not pulled, meaning that all components, including the contact switch 31, door opening transmission mechanism 32, cable-driven structure 36, and first limiting structure 33, are in their initial positions. That is, the cable position 361 is also in its initial position, and the communication device 313 transmits the information that the door unlocking is not controlled. Further, when the door opening lever 130 is pulled and is in its initial position… Figure 8In the current state, the communication device 313 transmits information to control door unlocking. However, due to a power outage or collision fault, door lock 300 cannot unlock. This can be achieved through software or hardware control. For example, in the event of a power outage or collision fault, the locking motor reverses, requiring mechanical unlocking (normally, the motor rotates forward and can be unlocked using signal control). For instance, the vehicle's exterior door handle 100 also includes an anomaly detection controller connected to the door controller 200. Upon detecting an abnormal scenario, including but not limited to the door lock 300 failing to release automatically, the electric drive failing to supply power to open the door, or a collision signal triggering, it will trigger control to allow only mechanical unlocking. Further details can be found by referring to... Figure 11 , Figure 11 This is a schematic diagram of another ending structure of the fourth embodiment of the vehicle exterior door handle of this application. Since electric unlocking is not possible, the door opening lever 130 is controlled to continue pulling, at which point it moves to the mechanical unlocking end position. At this point, the pull cable drives the structure 36 to rotate the pull cable position 361, thereby lengthening the door lock pull cable 37 to achieve mechanical unlocking. It is worth noting that the two-stage opening unit 30 can be used to directly open the door. If there is no power outage or collision fault, and the door is in a state of... Figure 8 In this state, electric unlocking can be completed. In the event of a power outage or collision malfunction, continue pulling the door to unlock. Figure 11 This allows the car doors to be unlocked, thus improving the intelligence and functionality of the door opening mechanism.

[0084] In one feasible embodiment, a first damping element 321 is provided in the door opening transmission mechanism 32. The first damping element 321 abuts against the door opening transmission mechanism 32 and is configured to always provide resistance opposite to the rotation direction of the door opening transmission mechanism 32. The second damping element 341 can be a spring. The spring is used for the second damping element 341 to contact the second limiting structure 35 and provide resistance to the rotation of the door opening transmission mechanism 32. The first damping element 321 and the second damping element 341 are described as providing resistance through springs. Of course, other devices can also be used. That is, when the door is pulled in two stages, the springs at both positions need to use greater force, and the force increases with each stage. This can avoid the problem of misoperation. For example, during the first stage of pulling the door, the first damping element 321 is the main force, while the second damping element 341 is in a non-working or initially working state (the force required for the initial working state is relatively small), and the resistance of the second damping element 341 can be ignored. However, when the door is pulled in two stages, the first damping element 321 and the second damping element 341 provide resistance simultaneously. Thus, during the second stage of pulling control, the vehicle's outer door handle 200 can be mechanically unlocked to open the door.

[0085] In one embodiment, the two-stage opening unit 30 controls the first-stage opening force and the second-stage opening force of the handle respectively through a first-stage opening control lever (mainly acting on the first damping element 321) and a second-stage opening control lever (acting jointly on the first damping element 321 and the second damping element 341). When the handle is opened in the first stage, the first-stage opening control lever acts on the handle. By analyzing and verifying the spring, the first-stage opening force of the handle meets the design requirements, thus enabling electric opening. The second-stage opening control lever is in an unloaded state when the handle is opened in the first stage and does not act on the handle. When the handle is pulled to a certain opening degree, the second-stage opening control lever contacts the first-stage control lever, that is, at this time the second damping element 341 is engaged, thereby generating a force acting on the handle. In other words, the handle adopts a pullable mechanical structure, and the handle is pulled in two stages. The first stage has a smaller opening force, which triggers the contact switch 31 during the opening process and electrically releases and unlocks the door. The second stage has a larger opening force, which allows for mechanical unlocking and pulling of the car door in an emergency. Therefore, the car door handle can be used to open the door via a micro switch or a position sensor, or it can be opened by pulling the handle a certain distance, or it can be unlocked by a mechanical cable by pulling the handle a second distance.

[0086] In one embodiment, after the door controller 200 unlocks the door based on signals from the external sensing unit 10, the internal button 20, or the two-stage opening unit 30, it opens the door to a preset angle under motor drive or under external pulling force.

[0087] In this embodiment, after the door is unlocked based on the signal control from the external sensing unit 10, the internal button 20, or the two-stage opening unit 30, it will open by its own pulling force or directly trigger the electric door opening driven by the motor, thereby expanding the functionality of the vehicle's exterior door handle 100. It is worth noting that, except for the second stage control of the two-stage opening unit 30, which requires external pulling force to open the door to a preset angle, other control methods can be selected according to the user's usage and actual scenario, using either motor-driven opening or external pulling force to open the door to a preset angle.

[0088] In one embodiment, the door opening mechanism 32 includes:

[0089] Drive shaft 322;

[0090] A rotating component 323 has a transmission shaft 322 passing through its central axis. The rotating component 323 is connected to the door opening rod 130. The rotating component 323 is equipped with a cable-driven structure 36, a first limiting structure 33, and a second limiting structure 35. The rotating component 323 is configured to drive the cable-driven structure 36, the first limiting structure 33, and the second limiting structure 35 to rotate synchronously when the door opening rod 130 is pulled.

[0091] In this embodiment, the door opening transmission mechanism 32 includes a transmission shaft 322 and a rotating component 323. The transmission shaft 322 and the rotating component 323 can rotate synchronously, or the rotating component 323 can rotate on the transmission shaft 322. Since the rotating component 323 is connected to the door opening lever 130, when the door opening lever 130 is pulled, it will drive the rotating component 323. Because the rotating component 323 is equipped with a cable-driven structure 36, a first limiting structure 33, and a second limiting structure 35, and rotates synchronously, the rotating component 323 will drive the cable-driven structure 36, the first limiting structure 33, and the second limiting structure 35 to rotate synchronously, thereby enabling the contact switch 31 and the car lock cable 37 to achieve corresponding control. Moreover, by designing dampers in the damping element 34 and the rotating component 323, the mechanism can automatically return to its initial position after the door opening lever 130 is completed (i.e., without pulling the door opening lever 130). Simultaneously, the pull cable position 361 of the rotating component 323 connects to the second end of the car lock pull cable 37. Therefore, when the door is opened mechanically, the pull cable drive structure 36 drives the pull cable position 361 to change, controlling the length of the car lock pull cable 37 to achieve the mechanical opening length. Of course, the door opening transmission mechanism 32 can also use other transmission methods, such as directly using a lever to connect the contact switch 31 and the door opening rod 130, or connecting the pull cable position 361 and the door opening rod 130. These will not be described in detail here.

[0092] It is worth noting that the entire two-stage opening unit 30 can be equipped with a door opening transmission mechanism 32. This mechanism directly uses a synchronously rotating cable drive structure 36, a first limiting structure 33, and a second limiting structure 35 to drive the door opening rod 130. When the door opening rod 130 is pulled, it synchronously drives the cable drive structure 36, the first limiting structure 33, and the second limiting structure 35 to rotate (around the same axis or fixed point). However, each of these structures needs a corresponding damper to automatically return to its initial position after rotation. Alternatively, the door opening transmission mechanism 32, the cable drive structure 36, the first limiting structure 33, and the second limiting structure 35 can be encapsulated as a single unit, such as a recessed structure. This allows the damping element 34 to be in contact with the contact switch 31 before the first limiting structure 33 contacts it, and the door lock cable 37 can be connected at any position on it to achieve mechanical door actuation, thus simplifying the overall design.

[0093] Based on the above embodiments of vehicle exterior door handles, a vehicle is proposed that includes the aforementioned vehicle exterior door handle.

[0094] In this embodiment, the vehicle's exterior door handle is connected to the door controller 200 via an external sensing unit 10 at a sensing position on the outer side 110 of the exterior door handle 100, an internal button 20 at a button position on the inner side 120 of the exterior door handle 100, and a two-stage opening unit 30 inside the exterior door handle 100. The door controller 200 can control the door to open based on the signals from the external sensing unit 10, the internal button 20, or the two-stage opening unit 30, thereby avoiding the phenomenon that the door can only be opened by a manual micro-switch. That is, the door is opened by controlling the signal from the external sensing unit 10, the internal button 20, or the two-stage opening unit 30, thus improving the functionality of the vehicle's exterior door handle 100.

[0095] In one embodiment, the vehicle includes a door controller 200, a door lock 300, and a door electric drive structure 400. The door controller 200 is electrically connected and / or signal connected to the vehicle exterior door handle 100, the door lock 300, and the door electric drive structure 400. The motor in the door electric drive structure is used to control the electric opening of the door.

[0096] In this embodiment, the vehicle includes a door controller 200, a door lock 300, and a door electric drive structure 400. The door controller 200 is electrically and / or signal-connected to the vehicle's exterior door handle 100, door lock 300, and door electric drive structure 400. Upon receiving a signal from the vehicle's exterior door handle 100, the controller judges the signal to determine whether the door lock 300 needs to be unlocked and whether electric door opening is required, thus controlling the door. The door electric drive structure 400 can combine a motor and a pulley to achieve electric door opening. The motor in the door electric drive structure controls the electric opening of the door; that is, the motor drives the pulley to open the door, or other electric door opening methods can be used, which are not limited here. Thus, door opening control is achieved based on various signals from the vehicle's exterior door handle 100, expanding the door opening control functionality of the vehicle's exterior door handle 100.

All equivalent structural transformations made under the technical concept of this application and using the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this application.
