Description

Technical Field

[0001] This invention relates to the technical field of components related to new energy vehicles, specifically a door switch assembly for new energy vehicles. Background Technology

[0002] Currently, the exterior door handles used in new energy vehicles are mostly concealed door handles, which are characterized by a sleek appearance and low wind resistance. Among various concealed door handle types, the rotary exterior door handle remains the primary type. See also Figure 1 and Figure 2 As shown, the handle base shell 300 is embedded in the door 100. An outer door handle 200 is provided inside the handle base shell 300. One end of the outer door handle 200 near the front of the car is hinged to the handle base shell 300, so that the other end of the outer door handle 200 can be tilted outward around the axis S. When a person grasps the outer door handle 200 and applies an outward pulling force F, the door lock 400 on the door 100 can be unlocked by the outer door cable 500 inside the door 100.

[0003] With existing exterior door handles of this type, if a person walks towards the door from the front of the vehicle, they are positioned on the side of the exterior door handle 200 closest to the front, and their hand is roughly perpendicular to the raised end of the handle 200, making it relatively convenient to grip. However, when a person walks towards the door from the rear of the vehicle, they are positioned on the side of the exterior door handle 200 closest to the rear, and their hand is roughly parallel to the raised end of the handle 200, making it less convenient to grip. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art: to provide an external door switch assembly for new energy vehicles, which enables a person's hand to be substantially perpendicular to the external door handle when the person is on either side of the door, making it convenient for the person to grip the door handle.

[0005] Therefore, one object of the present invention is to provide an external door switch assembly for a new energy vehicle, which includes a bottom shell with a receiving groove for accommodating a door handle. The door handle includes a first handle and a second handle disposed in the receiving groove. The connecting end of the first handle is hinged to one end of the receiving groove, so that the free end of the first handle can rotate out of the receiving groove or return to the receiving groove. The end of the second handle opposite to the connecting end is hinged to the free end of the first handle or to the other end of the receiving groove, so that the other end of the second handle can rotate out of the receiving groove or return to the receiving groove. When both ends of the first handle and both ends of the second handle are located in the receiving groove, the front end faces of the first handle and the second handle smoothly transition to the groove opening.

[0006] Combining the above technical solutions, two handles with opposite rotation directions are installed in a receiving slot. When a person approaches the door from the front of the vehicle, they can grasp the first handle. At this time, one end of the first handle is tilted up, making the first handle roughly perpendicular to the person's hand, which is convenient for the person to grasp. When a person approaches the door from the rear of the vehicle, they can grasp the second handle. Since the second handle rotates in the opposite direction to the first handle, one end of the second handle is tilted up, making the second handle roughly perpendicular to the person's hand, which is also convenient for the person to grasp. Ultimately, this allows people who need to open the door to get in the vehicle to grasp the door handle in a more comfortable posture and open the door, regardless of whether they are approaching from the front or rear of the vehicle.

[0007] Optionally, the front end face of the first handle has a recessed handle groove, and the second handle is placed in the handle groove. The end of the second handle opposite to the connecting end is hinged to the first handle, so that the other end of the second handle can rotate out of the handle groove or return to the handle groove. By placing the second handle on the first handle, the outer contour dimension of the first handle can be larger, making it easier for the hand to grip.

[0008] Optionally, the outer contour of the second handle matches the handle groove, and when the second handle is stationary in the handle groove, the front end face of the second handle is flush with the front end face of the first handle.

[0009] Optionally, the first handlebar is equipped with a position sensor for detecting the position of the second handlebar. The position sensor can communicate with the vehicle's infotainment system to obtain the real-time position of the second handlebar relative to the first handlebar.

[0010] Optionally, the first handle is provided with a miniature drive motor for driving the second handle.

[0011] Optionally, the end of the second handle away from the connecting end is hinged to the first handle via a rotating shaft, and a micro drive motor is provided on the bottom shell, with the drive shaft of the micro drive motor and the rotating shaft being connected in a disengaged manner. When the free end of the first handle is located in the receiving groove, the rotating shaft is connected to the drive shaft on the micro drive motor. When the free end of the first handle is outside the receiving groove, the rotating shaft is disengaged from the drive shaft on the micro drive motor.

[0012] Due to the limited internal space at the end of the first handle, the above-described solution of directly mounting the micro drive motor inside the first handle restricts the size of the micro drive motor and increases assembly difficulty. Mounting the micro drive motor on the bottom shell, however, allows for a wider range of size options and reduces assembly difficulty.

[0013] Optionally, the bottom shell is provided with a magnetic coupling, which includes an active magnetic rotor connected to the drive shaft of the micro drive motor and a driven magnetic rotor connected to the rotating shaft. When the free end of the first handle is located in the receiving groove, the active and driven magnetic rotors in the magnetic coupling are arranged opposite to each other and rotate synchronously. Using a magnetic coupling not only allows for a disengaged transmission connection between the micro drive motor and the rotating shaft, but also ensures that the active and driven magnetic rotors in the magnetic coupling do not directly contact each other during synchronous rotation, thus allowing the driven magnetic rotor to be embedded inside the first handle.

[0014] Optionally, the inner wall of the handle groove is provided with a shaft hole, the rotating shaft is fixed to the second handle and rotatably fitted in the shaft hole, the driven magnetic rotor is arranged in the shaft hole and fixed to the rotating shaft, and the active magnetic rotor is arranged in the bottom shell at the position corresponding to the driven magnetic rotor.

[0015] Optionally, the door switch assembly further includes a first cable and a second cable arranged between the door lock and the bottom housing. The first cable is connected to the door lock and the first handle respectively, so that the door lock can switch between the unlocked and locked states in response to the rotation of the first handle. One end of the second cable is connected to the door lock, and the other end is connected to a driver installed on the bottom housing. The driver is configured to drive the second cable to perform a stretching movement along its own length direction. The driver and the position sensor are respectively connected to the vehicle's infotainment system.

[0016] Optionally, the driver is an auxiliary motor, and the end of the second cable is fixed to the drive wheel on the output shaft of the auxiliary motor.

[0017] The above technical solution has the following advantages or beneficial effects: First, by setting two handles in a receiving slot with opposite rotation directions, people needing to open the door can grip the door handle with their hands perpendicular to each other, regardless of whether they approach the door from the front or rear of the vehicle, making unlocking and opening the door more comfortable and effortless. Second, by setting a handle groove on the first handle and placing the second handle inside the handle groove, the outer contour of the first handle can be made larger, making it more comfortable for the hand to grip. Finally, by mounting the micro drive motor that drives the second handle on the bottom shell and connecting it to the rotating shaft via a magnetic coupling, not only are the safety space requirements for the equipment inside the first handle reduced, but the rotating shaft and driven magnetic rotor can also be installed inside the first handle, improving dustproof and waterproof performance.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The following describes in detail, with reference to the accompanying drawings, a new energy vehicle door switch assembly according to an embodiment of the present invention.

[0023] For ease of description, the length direction in the following text is... Figures 6-9 The left and right directions, and the height direction are Figure 6 The up and down directions are also Figures 7-9 The direction perpendicular to the paper, and the width direction are Figures 7-9 The left and right directions are indicated by the direction of the front of the car and the right direction by the direction of the rear of the car.

[0024] Example 1 This invention provides an external door switch assembly for a new energy vehicle, as shown in the figure. It includes a bottom shell 1, and a recessed receiving groove 2 on the front side 1.1 of the bottom shell 1. The opening of the receiving groove 2 is located on the front side 1.1 of the bottom shell 1. A door handle is provided in the receiving groove 2. The door handle includes a first handle 3 and a second handle 4. The two handles are hinged to the two ends of the receiving groove 2 at opposite ends along the length direction, so that the two handles can swing outward around their respective hinge axes. The two handles are arranged side by side along the height direction, so that the rotation paths of the two handles are staggered and the two handles interfere with each other.

[0025] Specifically, the left end of the first handle 3 is hinged to the left end of the receiving groove 2, and the right end of the second handle 4 is hinged to the right end of the receiving groove 2. When both handles are retracted into the receiving groove 2, they are placed side by side along the height direction. When a person walks from the front of the vehicle, the first handle 3 faces outward and rotates towards the front of the vehicle, making it easier for the person to grasp the first handle 3 and pull towards the front of the vehicle to unlock and open the door 100. When a person walks from the rear of the vehicle, the second handle 4 faces outward and rotates towards the rear of the vehicle, making it easier for the person to grasp the second handle 4 and pull towards the rear of the vehicle to unlock and open the door 100.

[0026] It should be understood that rotary door handles are a common type of door handle in the field of new energy vehicles. Furthermore, if such door handles are concealed, a micro-motor inside the door 100 can drive the rotary door handle to open outwards when a person approaches the door 100. This is a standard technology for existing rotary concealed door handles. In addition, new energy vehicles themselves have numerous sensors and cameras for sensing people and objects outside the vehicle. Therefore, obtaining the location information of people using the vehicle's own sensors and cameras is simple and easy. The vehicle's infotainment system obtains the location information of people through sensors and cameras, and then controls the corresponding first or second door handle to turn outwards. This is a standard technical method in the field of vehicle system control and will not be elaborated upon here.

[0027] Example 2 In the above embodiment 1, two door handles need to be placed in the original receiving slot 2, so the size of a single door handle will be small, affecting the grip of the person.

[0028] To address this, the present invention provides an external door switch assembly for a new energy vehicle, as shown in the figure. It includes a base shell 1, and a recessed receiving groove 2 on the front side 1.1 of the base shell 1. The opening of the receiving groove 2 is located on the front side 1.1 of the base shell 1. A door handle is provided in the receiving groove 2. The door handle includes a first handle 3 and a second handle 4. The left end of the first handle 3 is a connecting end, and the right end is a free end. The connecting end is hinged to the left end of the receiving groove 2 so that the free end of the first handle 3 can rotate outward, that is, the free end can rotate towards the front of the vehicle to the outside of the receiving groove 2 or return to the receiving groove 2 towards the rear of the vehicle. The end of the second handle 4 away from the connecting end is hinged to the free end of the first handle 3 so that the other end of the second handle 4 can rotate outward when the free end of the first handle 3 is located in the receiving groove 2, that is, the other end of the second handle 4 rotates to the outside of the receiving groove 2 or returns to the receiving groove 2.

[0029] Furthermore, when both ends of the first handle 3 and both ends of the second handle 4 are located within the receiving groove 2, the front end face 3.1 of the first handle 3 and the front end face 4.1 of the second handle 4 smoothly transition to the opening of the receiving groove 2. In this embodiment, when the switch assembly is installed on the door 100, the front surface 1.1 of the bottom shell 1 is flush with the outer surface of the door 100, so that the surface formed by splicing the front end face 3.1 of the first handle 3 and the front end face 4.1 of the second handle 4 can cover the entire opening of the receiving groove 2.

[0030] Example 3 Based on the improvements of Embodiment 2 above: the front end face 3.1 of the first handle 3 has a recessed handle groove 5, and the second handle 4 is placed in the handle groove 5. The end of the second handle 4 away from the connecting end of the first handle 3 is hinged to the first handle 3, so that the other end of the second handle 4 can rotate out of the handle groove 5 or return to the handle groove 5. In this embodiment, when the second handle 4 is accommodated in the handle groove 5, the overall size and shape of the first handle 3 are basically the same as the existing door handle. Therefore, for a person walking from the front of the vehicle who needs to open the door, the way he / she grasps the first handle 3 and rotates to open the car door 100 is the same as the existing hidden door handle with a rotating method. When a person approaches the car door 100 from the rear of the vehicle, the camera on the vehicle can capture the person's position information. After the owner gives the control command to open the door lock 10, the vehicle system 600 of the new energy vehicle can control the second handle 4 to rotate outward based on the above position information. At this time, for the person opening the door, after grasping the second handle 4, he / she can open the door lock 10 and open the car door 100 by applying a pulling force.

[0031] It should be understood that, in this embodiment, since the second handle 4 is installed in the handle groove 5 on the first handle 3, if the linkage between the second handle 4 and the door lock 10 is carried out by the existing pure mechanical cable, the cable needs to extend through the cable channel inside the first handle 3 to the bottom shell 1, and finally connect to the door lock 10 through the space inside the door 100.

[0032] Preferably, the outer contour of the second handle 4 matches the handle groove 5, and the front end face 4.1 of the second handle 4 is configured to be flush with the front end face 3.1 of the first handle 3 when the second handle 4 is rotated into the handle groove 5 until the second handle 4 is stationary in the handle groove 5.

[0033] Example 4 Based on the improvements of Embodiment 3 above: such as Figure 11 As shown, the first handle 3 is equipped with a miniature drive motor 7 for driving the second handle 4. The miniature drive motor 7 is a commercially available product commonly used in various types of concealed door handles, and its specific structure will not be described in detail here. The miniature drive motor 7 is communicatively connected to the vehicle's infotainment system 600. When the vehicle's camera detects a person approaching from the rear of the vehicle, the infotainment system 600 can control the miniature drive motor 7 based on the image information from the camera after the driver gives the door opening control command. This controls the second handle 4 to rotate outward from its initial state within the handle slot 5. When a person grasps the second handle 4 and applies a pulling force, the door lock 10 can be unlocked and the car door 100 can be opened. During this process, the person's hand applies an outward pulling force to the second handle 4, which is more effortless than the pushing force required for existing rotary door handles.

[0034] Example 5 In the above embodiment 4, when the micro drive motor 7 drives the second handle 4 to rotate outward, the first handle 3 is located in the receiving groove 2. However, when the first handle 3 rotates outward, the second handle 4 does not need to rotate outward from the handle groove 5. Considering the limited internal space on the first handle 3, the preferred embodiment based on embodiment 4 is as follows: the end of the second handle 4 away from the connecting end is hinged to the first handle 3 by a rotating shaft 8. The bottom shell 1 is provided with a micro drive motor 7, and the drive shaft of the micro drive motor 7 and the rotating shaft 8 are connected in a disengaged manner. Specifically, when the free end of the first handle 3 is located in the receiving groove 2, the rotating shaft 8 is connected to the drive shaft on the micro drive motor 7. When the free end of the first handle 3 is located outside the receiving groove 2, the rotating shaft 8 is disengaged from the drive shaft on the micro drive motor 7, that is, the rotating shaft 8 and the drive shaft switch from the initial transmission connection state to the two being disengaged.

[0035] Optionally, gears are provided on the rotating shaft 8 and the drive shaft respectively, and the gears on the rotating shaft 8 and the drive shaft mesh or disengage with each other as the first handle 3 rotates.

[0036] Optionally, the rotating shaft 8 and the drive shaft on the micro drive motor 7 are connected or disconnected via a non-contact coupling. Specifically, the bottom shell 1 is provided with a magnetic coupling 9, which includes an active magnetic rotor 9.1 and a driven magnetic rotor 9.2. The active magnetic rotor 9.1 is fixed to the drive shaft on the micro drive motor 7, and the driven magnetic rotor 9.2 is fixed to the rotating shaft 8. When the free end of the first handle 3 is located in the receiving groove 2, the active magnetic rotor 9.1 and the driven magnetic rotor 9.2 are opposite each other and can rotate synchronously under the magnetic force between them.

[0037] Furthermore, such as Figure 10 As shown, both the active magnetic rotor 9.1 and the driven magnetic rotor 9.2 are disc-shaped structures. Shaft holes 5.1 are provided on both sides of the inner wall of the handle groove 5. The rotating shaft 8 is fixed to the second handle 4, and both ends of the rotating shaft 8 are rotatably fitted into the shaft holes 5.1. The driven magnetic rotor 9.2 is fixedly connected to the end of the rotating shaft 8 and extends into the shaft hole 5.1 along with the end of the rotating shaft 8. A mounting cavity is provided in the bottom shell 1 at the position corresponding to the shaft hole 5.1. The active magnetic rotor 9.1 is arranged in the mounting cavity, and the drive shaft of the micro drive motor 7 is connected to it. Thus, when the free end of the first handle 3 is located in the receiving groove 2, the active magnetic rotor 9.1 and the driven magnetic rotor 9.2 are opposite each other and are connected by non-contact transmission through mutual magnetic force. In this embodiment, the driven magnetic rotor 9.2 is hidden in the shaft hole 5.1, which reduces the installation space requirement inside the first handle 3 and ensures that the outer surface of the first handle 3 is intact, providing better waterproofing and dustproofing.

[0038] Example 6 The first handlebar 3 is equipped with a position sensor 6 for detecting the position of the second handlebar 4. Specifically, the position sensor 6 is an angle sensor, including but not limited to, a Hall sensor, for detecting the rotational position of the second handlebar 4. The position sensor 6 is communicatively connected to the vehicle's infotainment system 600. On the one hand, it can determine the real-time position of the second handlebar 4 and issue a fault warning when the second handlebar 4 fails to return to the handlebar slot 5; on the other hand, the vehicle infotainment system 600 can obtain the real-time position information of the second handlebar 4 through the position sensor 6 while controlling the micro drive motor 7 to drive the second handlebar 4 to rotate outward from the handlebar slot 5, thus preventing damage to the second handlebar 4 after it has over-traveled.

[0039] Example 7 In existing technologies, the linkage between the outer door handle 200 and the door lock 400 of the concealed door handle used in new energy vehicles is mainly divided into two types: linkage through a purely mechanical cable structure or linkage through electronic control. The electronic control linkage refers to setting a special sensor on the outer door handle 200 to sense human hand movements. The sensor on the outer door handle 200 detects the action of a human hand gripping the outer door handle 200 and sends out a detection signal. After receiving the detection signal, the vehicle system 600 sends a control command to drive the drive motor of the corresponding door lock 400. Finally, the drive motor realizes the unlocking or locking of the door lock 400.

[0040] Based on the preferred embodiment of the above, since the two handles are respectively hinged to the bottom shell 1, there is no mutual interference between the two handles. Therefore, the first handle 3 and the second handle 4 can be linked with the door lock 10 using existing conventional purely mechanical cable structures or existing electronic control methods.

[0041] Based on the preferred embodiments 2 to 6 above, since the second handle 4 is connected to the first handle 3, in order to achieve linkage between the door handle and the door lock 10, the improvement of this embodiment is as follows: Figure 11 As shown, the external door switch assembly also includes a first cable 11 and a second cable 12 arranged between the door lock 10 and the base shell 1. The first cable 11 is connected to the door lock 10 and the first handle 3, respectively, so that the door lock 10 can switch between the unlocked and locked states in response to the rotation of the first handle 3. One end of the second cable 12 is connected to the door lock 10, and the other end is connected to the driver 13 mounted on the base shell 1. The driver 13 is configured to drive the second cable 12 to perform a stretching movement along its own length. The driver 13 is communicatively connected to the vehicle system 600 of the new energy vehicle. Thus, after the vehicle system 600 issues a control command, the driver 13 can drive the second cable 12, which controls the opening and closing of the door lock 10. Specifically, the driver 13 is an auxiliary motor installed inside the door 100. One end of the second cable 12 is connected to the door lock 10, and the other end is fixed to the drive wheel on the output shaft of the auxiliary motor, thereby driving the second cable 12 to perform a stretching action through the rotation of the drive wheel.

[0042] It should be understood that the opening and closing of the door lock 10 by pulling the cable in this embodiment is a conventional technology in the art. Therefore, the specific structure between the cable and the door lock 10 will not be described in detail here.
