[0002] This application relates to handle systems, and more particularly to a door handle system for a vehicle, a vehicle including the handle system, and a control method for the handle system. Background Technology

[0003] The vehicle door is equipped with a handle, which includes a handle base fixed to the door by sheet metal and a handle body movable relative to the handle base. Some existing concealed handles retract relative to the handle base via a drive mechanism when not in use, so that the outer surface of the handle body is approximately flush with the vehicle door. When it is necessary to open the door from the outside, the drive mechanism first extends the handle body relative to the handle base, allowing the operator to pull the handle body from the outside to unlock the vehicle door's electronic locking device, thereby opening the door. Summary of the Invention

[0004] This application provides a handle system for a door of a vehicle with an electronic locking device, comprising: a handle base, a handle body, a drive mechanism, a position sensing device, a sensed element, and a control device. The handle body is mounted to the handle base and is movable relative to the handle base between a retracted position, a first extended position, and a second extended position. The drive mechanism is configured to drive the handle body to extend from the retracted position toward the first extended position and to retract from the first extended position toward the retracted position. The position sensing device includes at least two position sensors disposed on one of the handle base and the handle body, spaced apart in the direction of movement of the handle body. The sensed element is disposed on the other of the handle base and the handle body and has a sensed area. The sensed element is configured to be detected by a position sensor entering the sensed area when either of the at least two position sensors enters the sensed area. The control device is communicatively connected to the position sensing device, the drive mechanism, and the electronic locking device. The control device is configured to determine whether the handle body has reached the retracted position, the first extended position, or the second extended position based on whether the at least two position sensors detect the sensed element, and to control the drive device to stop driving the handle body to retract when the handle body has reached the retracted position, to control the drive device to stop driving the handle body to extend when the handle body has reached the first extended position, and to control the electronic lock device to unlock when the handle body has reached the second extended position.

[0005] In some embodiments, the at least two position sensors include a first position sensor and a second position sensor, wherein the second position sensor is located on the outermost side and the first position sensor is located on the innermost side in the direction of movement of the handle body. When the handle body reaches the retracted position, the second position sensor detects the sensed element. When the handle body reaches the first extended position, the first position sensor detects the sensed element. And when the handle body reaches the second extended position, none of the at least two position sensors detect the sensed element.

[0006] In some embodiments, the control device determines that the handle body has reached the retracted position based on the detection signal of the second position sensor, determines that the handle body has reached the first extended position based on the detection signal of the first position sensor, and determines that the handle body has reached the second extended position based on the detection signals of the first position sensor and the second position sensor.

[0007] In some embodiments, the at least two position sensors further include a third position sensor, wherein the third position sensor is disposed between the first position sensor and the second position sensor. The control device determines that the handle body has reached the retracted position based on the detection signal of the second position sensor, determines that the handle body has reached the first extended position based on the detection signal of the first position sensor, and determines that the handle body has reached the second extended position based on the detection signals of the first position sensor, the second position sensor, and the third position sensor combined.

[0012] In some embodiments, the handle system further includes a light module integrated on the circuit board, which is turned on or off based on the position of the handle body.

[0013] In some embodiments, the sensing element is disposed on the inner wall of the handle base, and the at least two position sensors are encapsulated inside the handle body.

[0014] In some embodiments, the handle body has a grip portion and a first pillar and a second pillar disposed on opposite sides of the grip portion. The second pillar has a greater travel distance than the first pillar during the movement from the retracted position to the second extended position; and the position sensing device is encapsulated inside the second pillar of the handle body.

[0015] This application provides a vehicle in a second aspect, comprising: a door, an electronic locking device, and a handle system according to any one of the first aspects. The electronic locking device is disposed on the door and configured to lock or unlock the door.

[0016] This application provides a method for controlling a handle system in a third aspect. The handle system includes a sensed element, at least two position sensors, a handle body, a handle base, and a drive device. The sensed element is disposed on one of the handle body and the handle base, and the at least two position sensors are disposed on the other of the handle body and the handle base. The method includes the following steps: detecting the relative position of the sensed element with respect to the at least two position sensors using the at least two position sensors; determining the position of the handle body relative to the handle base based on the detection signals obtained from the at least two position sensors; and controlling the drive device to stop driving the handle body to retract, stop driving the handle body to unfold, or control an electronic lock device to unlock based on the position of the handle body relative to the handle base.

[0017] In some embodiments, the step of determining the position of the handle body relative to the handle base based on the detection signals obtained from the at least two position sensors includes: determining that the handle body has reached a first extended position when the first position sensor located on the innermost side of the at least two position sensors in the direction of movement of the handle body detects the sensed component; determining that the handle body has reached a retracted position when the second position sensor located on the outermost side of the at least two position sensors in the direction of movement of the handle body detects the sensed component; and determining that the handle body has reached a second extended position when none of the sensors in the at least two position sensors detect the sensed component.

[0018] In some embodiments, the step of controlling the drive device to stop driving the handle body to retract, stop driving the handle body to unfold, or control the electronic lock device to unlock based on the position of the handle body relative to the handle seat includes: stopping driving the handle body to unfold when the handle body reaches the first unfolded position; stopping driving the handle body to retract when the handle body reaches the retracted position; and controlling the electronic lock device to unlock when the handle body reaches the second unfolded position.

[0019] The handle system of this application, by providing a position sensing device and a sensed element that work together on the handle base and handle body, can accurately indicate whether the handle body is in a retracted position, a first extended position, or a second extended position relative to the handle base.

Detailed Implementation

[0023] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer," are used herein to describe various exemplary structural parts and elements, their use is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be arranged in different orientations, these terms indicating direction are illustrative only and should not be considered limiting.

[0024] Figures 1A to 3D The diagram illustrates the positional relationship between the handle body 110 and the handle base 101 of a handle system 100 according to an embodiment of this application, with the handle body 110 in different positions. Figure 1A and Figure 1BIn the middle, the handle 110 is in the retracted position, Figure 2A and Figure 2B In the middle, the handle 110 is in the first unfolded position, in Figure 3A and Figure 3B In the middle, the handle 110 is in an exemplary second unfolded position, Figure 3C and Figure 3D In the middle, the handle body 110 is in another exemplary second unfolded position.

[0025] like Figures 1A to 3D As shown, the handle system 100 is used for the door 107 of a vehicle 1060 with an electronic locking device 170 (see...). Figure 10 An electronic lock device 170 is installed on door 107 and is used to lock or unlock door 107. When the electronic lock device 170 is locked, door 107 cannot be opened. Door 107 can only be opened when the electronic lock device 170 is unlocked.

[0026] The handle system 100 includes a handle base 101, a handle body 110, a drive unit 160, and a control unit 150. The handle base 101 is fixed to the door 107 of the vehicle. The handle body 110 is mounted to the handle base 101 and is movable relative to the handle base 101 between a retracted position, a first extended position, and a second extended position. The control unit 150 is communicatively connected to the drive unit 160 and the electronic lock device 170 to control the drive unit 160 to drive the movement of the handle body 110 and to control the unlocking of the electronic lock device 170.

[0027] The handle body 110 is mounted to the handle base 101, for example, via a linkage mechanism. The linkage mechanism is connected to a drive device 160 to drive the linkage mechanism, thereby driving the handle body 110 to extend from a retracted position toward a first extended position and retract from the first extended position toward a retracted position. In the illustrated embodiment, the linkage mechanism includes a first link 213 and a second link 214. In some embodiments, the drive device 160 is an electric actuator. Those skilled in the art will understand that the linkage mechanism can be designed with any structure to meet specific needs, as long as it can drive the handle body 110 to reciprocate between the retracted position and the first extended position via the drive device 160.

[0028] The handle body 110 moves from a first extended position to a second extended position by a pulling force applied by the operator from outside the handle system 100. In this embodiment, the handle body 110 is generally hollow and rectangular, with a cavity 218 formed in the middle for the operator's hand to operate on. The handle body 110 has a grip portion 116 on the front side of the cavity 218. The handle body 110 has a grip portion 116 on opposite sides of the grip portion 116 (e.g., Figure 2BThe handle body 110 has a first support column 111 and a second support column 112 on both sides. In the illustrated embodiment, a first connecting rod 213 connects the first support column 111 of the handle body 110 and the inner wall of the handle seat 101, and a second connecting rod 214 connects the second support column 112 of the handle body 110 and the inner wall of the handle seat 101. When the operator's hand is inserted into the cavity 218, the operator's hand can grasp the grip part 116 to apply a pulling force to the handle body 110, so that the handle body 110 moves from the first unfolded position to the second unfolded position under the action of the external pulling force applied by the operator.

[0029] In the illustrated embodiment, the handle system 100 also includes an elastic component, such as a torsion spring (not shown), disposed on the handle seat 101. The torsion spring is operatively connected to the second link 214. After the handle body 110 is released by the operator, the handle body 110 in the second extended position can move to the first extended position by the restoring force provided by the torsion spring. Thus, under the action of the external pulling force applied by the operator and the restoring force of the torsion spring, the handle body 110 can reciprocate between the first extended position and the second extended position.

[0030] When the handle 110 is in such a position Figure 1A and Figure 1B In the retracted position shown, the handle body 110 is substantially housed within the handle base 101, and the outer surface of the handle body 110 is substantially flush with the outer surface of the handle base 101. When the handle base 101 is installed in the vehicle door 107, the outer surface of the handle body 110 is also substantially flush with the outer surface of the door 107. Therefore, the handle body 110 can be visually concealed within the vehicle door 107.

[0031] When the handle system 100 receives a drive signal (such as a drive signal indicating that the door is open, such as a car key approaching or a car key unlocking), the control device 150 controls the drive device 160 to push the handle body 110 approximately parallel to the door, causing the handle body 110 to move from... Figure 1A and Figure 1B The retracted position shown is translated and expanded to the position shown. Figure 2A and Figure 2B The first unfolded position is shown.

[0032] When the handle 110 reaches as Figure 2A and Figure 2BIn the first unfolded position, control device 150 controls drive device 160 to stop unfolding handle body 110. In the first unfolded position, the outer surface of handle body 110 is approximately parallel to handle base 101, and the first support 111 and the second support 112 move approximately the same distance relative to handle base 101. Handle body 110 extends outward relative to handle base 101 to expose cavity 218 and grip portion 116 on handle body 110, allowing the operator to insert their hand into cavity 218 and grasp grip portion 116 to pull handle body 110.

[0033] When the operator pulls the handle body 110, the external pulling force drives the handle body 110 to rotate approximately around the inner end of the first support column 111 connected to the first connecting rod 213 as a fulcrum. The second support column 112 of the handle body 110 rotates away from the handle seat 101. The second connecting rod 214 of the linkage mechanism moves outward with the second support column 112. This continues until the handle body 110 rotates to the desired position. Figure 3A and Figure 3B The second deployment position is shown. During this process, the torsion spring accumulates restoring force.

[0034] When the handle 110 reaches as Figure 3A and Figure 3B In the second unfolded position shown, the control device 150 unlocks the electronic lock device 170 on the vehicle door 107, allowing the operator to continue pulling the handle 110 to open the vehicle door 107. During this process, the torsion spring further accumulates restoring force.

[0035] When the operator stops pulling the handle 110, the handle 110 returns to its original position under the restoring force of the torsion spring. Figure 2A and Figure 2B The first extended position is shown. When the handle system 100 receives another drive signal (e.g., a door closing operation signal), the control device 150 controls the drive device 160 to drive the handle body 110 to translate to the retracted position via a linkage mechanism. When the handle body 110 retracts to reach the position shown... Figure 1A and Figure 1B When the handle body is in the retracted position as shown, the control device 150 stops driving the handle body to retract.

[0036] Thus, the handle body 110 of the handle system 100 can move between a retracted position, a first extended position, and a second extended position.

[0037] In some emergency situations, the handle 110 can be rotated directly from the retracted position to another second extended position. This second extended position is different from the first one described above, but both positions can trigger the electronic lock device 170 to unlock. In this case, when the handle 110 is in the following position... Figure 1A and Figure 1BIn the retracted position shown, the operator can press the side of the handle 110 closest to the first support 111, causing the side of the handle 110 closest to the second support 112 to extend outward. After exposing the cavity 218, the operator can forcibly pull the grip 116 to move the handle 110 from the position shown. Figure 1A and Figure 1B The retraction position shown is directly rotated to the position shown. Figure 3C and Figure 3D The second unfolded position is shown. When the handle body 110 is in the position shown... Figure 3C and Figure 3D In the second unfolded position shown, the control device 150 can also control the electronic lock device 170 on the vehicle door 107 to unlock, allowing the operator to open the vehicle door 107.

[0038] The handle system 100 also includes a position sensor 120. Figure 1A The enlarged frame 103 shows the position sensing device 120 and the sensed element 105. Figures 5A-6C (Shown in more detail in the illustration). The position sensing device 120 is communicatively connected to the control device 150. The position sensing device 120 is disposed on one of the handle base 101 and the handle body 110, and the sensed element 105 is disposed on the other of the handle base 101 and the handle body 110, so that the position sensing device 120 and the sensed element 105 can move relative to each other. The position sensing device 120 detects the relative position of the sensed element 105 with respect to the position sensing device 120 and sends a corresponding detection signal to the control device 150. The control device 150 determines the relative position of the handle base 101 and the handle body 110 based on the detection signal. In the illustrated embodiment, the position sensing device 120 is encapsulated inside the handle body 110. The sensed element 105 is disposed on the inner wall of the handle base 101. As an example, the second pillar 112 of the handle body 110 is hollow and has a cavity 115, and the position sensing device 120 is encapsulated in the cavity 115 of the second pillar 112 and is located near the top of the second pillar 112. The sensing element 105 is located on the inner side of the top wall of the handle base 101.

[0039] In the illustrated embodiment, during the movement of the handle body 110 from the retracted position to the first extended position, the first support 111 and the second support 112 of the handle body 110 simultaneously translate. During the movement of the handle body 110 from the first extended position to the second extended position, the handle body 110 rotates around the inner end of the first support 111 as a fulcrum. Therefore, the travel distance of the second support 112 is greater than that of the first support 111. Thus, placing the position sensing device 120 on the second support 112 allows for a more accurate detection of the handle body 110's position.

[0040] As will be understood by those skilled in the art, in some embodiments, the position sensing device 120 may also be encapsulated on the right side of the second support 112, with the sensing element 105 correspondingly disposed on the inner side of the right side wall of the handle seat 101.

[0041] In some embodiments, the sensed element 105 has a sensed area S (see Figures 5A-6C (As shown). The position sensing device 120 includes at least two position sensors 425 (see...). Figure 4A and 4B As shown, at least two position sensors 425 are arranged spaced apart in the direction of movement of the handle body 110. When the relative positions of the at least two position sensors 425 with respect to the sensed element 105 are such that either of the at least two position sensors 425 enters the sensed area S of the sensed element 105, the sensed element 105 can be detected by the position sensor entering the sensed area S. When the relative positions of the at least two position sensors 425 with respect to the sensed element 105 are such that at least one position sensor 425 leaves the sensed area S of the sensed element 105, the sensed element 105 cannot be detected by the position sensor leaving the sensed area S. Depending on whether the sensed element 105 is detected, each position sensor can emit a corresponding detection signal to indicate the position of the handle body 110 relative to the handle base 101.

[0042] In this embodiment, the sensed element 105 is a magnet, and the sensed area S is the magnetic field of the magnet. The position sensor 425 is a Hall sensor, used to detect the magnetic field of the magnet. In some more specific embodiments, the Hall sensor is a switch-type Hall sensor. The switch-type Hall sensor generates a low-level or high-level signal depending on whether a magnet is detected. In some specific embodiments, the switch-type Hall sensor can emit a low-level signal when it detects a magnet and a high-level signal when it does not detect a magnet. Compared to other detection devices, the Hall sensor has higher detection accuracy while being smaller in size, making it particularly suitable for use in narrow spaces encapsulated within the second support 112 of the handle body 110. In other embodiments, the position sensor can also be other types of position sensors.

[0043] Therefore, by setting at least two position sensors of the sensing element 105 and the position sensing device 120 at corresponding positions, the control device 150 can determine whether the handle body 110 has reached the retracted position, the first extended position, or the second extended position based on whether the position sensors detect the sensing element 105. This will be discussed later. Figures 5A-5D as well as Figures 6A-6CDetailed description. Those skilled in the art will understand that in other embodiments, the sensing element 105 may be encapsulated inside the handle body 110, while the position sensing device 120 may be disposed on the inner wall at a corresponding position on the handle seat 101.

[0044] Figure 4A and Figure 4B The specific structure of the position sensing device 120 is shown. Figure 4A A three-dimensional structural diagram of the position sensing device 120 is shown. Figure 4B An exploded view of the position sensing device 120 is shown. Figure 4A and Figure 4B As shown, the position sensing device 120 includes a housing 421 and a circuit board 422. The housing 421 is mounted to the inner side of the top wall of the second support 112 of the handle body 110, for example, by adhesive bonding. The circuit board 422 is mounted in the housing 421. Individual position sensors 425 are integrated on the circuit board 422, and the circuit board 422 connects the individual position sensors 425 to a power supply and control device 150 to supply power to the position sensors 425 and output the detection signals generated by the position sensors 425 to the control device 150.

[0045] The housing 421 is a hollow, elongated shape with an opening at the front. The length of the housing 421 is approximately the same as the length of the second support column 112. The hollow housing 421 facilitates the housing of the circuit board 422 and provides some space for heat dissipation. The circuit board 422 is approximately rectangular and is inserted into the housing 421 through the opening at the front. After a handle cover (not shown) is fitted to the front of the handle body 110, the opening at the front of the housing 421 can be closed by the handle cover. In the illustrated embodiment, the length of the housing 421 is approximately equal to or slightly greater than the length of the circuit board 422. A pair of ribs 424 are provided on the inner sides of the left and right walls of the housing 421. The pair of ribs 424 extend along the length of the housing 421 and are spaced parallel to each other in the height direction of the housing 421, with the spacing matching the thickness of the circuit board 422. Therefore, the circuit board 422 can be inserted into the housing 421 through the front opening until it abuts against the rear wall of the housing 421, and the left and right edges of the circuit board 422 can be engaged between a pair of protruding ribs 424 on each side wall of the housing 421 to ensure that the circuit board 422 does not move relative to the housing 421. When the housing 421 is fixed to the handle body 110, the circuit board 422 will not move relative to the handle body 110. In this embodiment, the bottom of the front side of the housing 421 also has a notch 423, which allows wires or lines connected to the circuit board 422 to pass through, so that the wiring harness can be more neat.

[0046] Position sensor 425 is integrated above circuit board 422, facing handle base 101, to facilitate detection of the sensed element 105 located on the inner side of the top wall of handle base 101. In the illustrated embodiment, position sensing device 120 includes three position sensors: a first position sensor 425a, a second position sensor 425c, and a third position sensor 425b. The first position sensor 425a, the third position sensor 425b, and the second position sensor 425c are arranged spaced apart along the length of circuit board 422. Furthermore, the three position sensors are also arranged spaced apart along the direction of movement of handle body 110. The second position sensor 425c is located outside the first position sensor 425a, and the third position sensor 425b is located between the second position sensor 425c and the first position sensor 425a.

[0047] When the circuit board 422 is fixed relative to the handle body 110, the positions of the three position sensors relative to the handle body 110 are also fixed. Therefore, based on whether each position sensor 425 can detect the sensed element 105 on the handle base 101, the position of the handle body 110 relative to the handle base 101 can be indicated, for example, whether the handle body 110 has reached the retracted position, the first extended position, or the second extended position. The control device 150 identifies the position of the handle body 110 through the signals emitted by the three position sensors and takes corresponding actions. For example, when the control device 150 determines that the handle body 110 has reached the retracted position, it controls the drive device 160 to stop driving the handle body 110 to retract. When the control device 150 determines that the handle body 110 has reached the first extended position, it controls the drive device 160 to stop driving the handle body 110 to extend. When the control device 150 determines that the handle body 110 has reached the second extended position, it controls the electronic lock device 170 to unlock.

[0048] In some embodiments, the handle system 100 may further include a light module 438. The light module 438 is also integrated on the circuit board 422 and is turned on or off based on the position of the handle body 110. In some embodiments, the light module 438 includes an LED light that is turned on when the handle body 110 is in a first extended position and turned off when the handle body 110 is in a retracted position. In some embodiments, the light module 438 emits different light colors when the handle body 110 is in different positions. By providing the light module 438, the handle system 100 can also have lighting effects. Those skilled in the art will understand that the light module 438 can diffuse light through light guides or lampshades.

[0049] The handle system 100 of this embodiment, by setting up a circuit board 442, can concentrate at least two position sensors on a single circuit board 422, which not only has sufficient detection accuracy but also saves the layout space of the position sensors.

[0050] Figures 5A-5D A simplified schematic diagram showing the relative positions of the handle seat 101 and the handle body 110 during movement of the handle body 110 in a handle system according to an embodiment of this application is provided to illustrate the position detection principle of the position sensing device 120. The diagram illustrates the relative positions of the sensed element 105 and the position sensing device 120. Figures 5A-5D The approximate value shown is Figures 1A-1B The handle system 100 is shown in the diagram with respect to the relative positions of the handle base 101 and the handle body 110 when viewed from the left. From this perspective, the handle body 110 moves from the inside out relative to the handle base 101. Figures 5A-5D The movement proceeds from left to right. Figures 5A-5D In the illustrated embodiment, the position sensing device includes three position sensors. The control device 150 determines that the handle body 110 has reached the first extended position based on the detection signal of the first position sensor 425a, determines that the handle body 110 has reached the retracted position based on the detection signal of the second position sensor 425c, and determines that the handle body 110 has reached the second extended position based on the detection signals of the first position sensor 425a, the second position sensor 425c, and the third position sensor 425b.

[0051] Figure 5A The relative positions of the handle base 101 and the handle body 110 are shown when the handle body 110 is in the retracted position. Figure 5B The relative positions of the handle base 101 and the handle body 110 are shown during the movement of the handle body 110 from the retracted position to the first extended position. Figure 5C The relative positions of the handle base 101 and the handle body 110 are shown when the handle body 110 is in the first extended position. Figure 5D This shows the relative positions of the handle base 101 and the handle body 110 when the handle body 110 is in the second extended position. Table 1 shows the relative positions of the handle base 101 and the handle body 110. Figures 5A-5D In this embodiment, the detection signals are emitted by the various position sensors of the position sensing device. The detection signals include a first signal and a second signal emitted by the first position sensor 425a, a third signal and a fourth signal emitted by the second position sensor 425c, and a fifth signal and a sixth signal emitted by the third position sensor 425b.

[0052] Table 1. Detection signals emitted by each position sensor like Figure 5A As shown, the handle body 110 is in the retracted position. The handle body 110 is roughly as follows: Figure 1B As shown, it is entirely located within the handle base 101. The handle body 110 is located at the leftmost position relative to the handle base 101 (i.e., Figure 1B The topmost position). At this time, the outermost part of the position sensing device 120 (i.e., the position at the very top). Figures 5A-5C The second position sensor 425c (located on the far right) is within the sensing area S of the sensed element 105, therefore it can detect the sensed element 105 and generate a third signal. The third signal is a low-level signal. The first position sensor 425a and the third position sensor 425b are not within the sensing area S, therefore neither detects the sensed element 105. The first position sensor 425a generates a second signal, and the third position sensor 425b generates a sixth signal. Both the second and sixth signals are high-level signals.

[0053] When handle 110 is arranged as follows Figure 5A As the arrow in the diagram moves from the retracted position to the right toward the first extended position, the second position sensor 425c moves away from the sensing area S of the sensed element 105 until it reaches the position indicated by the arrow. Figure 5B The location shown.

[0054] like Figure 5B As shown, the handle 110 is moved from its retracted position but has not yet reached its first extended position. At this time, the third position sensor 425b in the middle of the position sensing device 120 is in the sensing area S of the sensed member 105, so the third position sensor 425b can detect the sensed member 105 and generate a fifth signal. The fifth signal is a low-level signal. Meanwhile, the first position sensor 425a and the second position sensor 425c are not in the sensing area S, so neither detects the sensed member 105. The first position sensor 425a generates a second signal, and the second position sensor 425c generates a fourth signal. Both the second and fourth signals are high-level signals.

[0055] When handle 110 is arranged as follows Figure 5B As the arrow in the image continues to move to the right relative to the handle base 101 towards the first unfolded position, the third position sensor 425b also gradually moves away from the sensing area S of the sensed element 105 until it reaches the position indicated by the arrow. Figure 5C The first unfolded position is shown.

[0056] like Figure 5CAs shown, the handle body 110 is in the first extended position. Most of the handle body 110 is located outside the handle base 101. At this time, the leftmost first position sensor 425 of the position sensing device 120 is located in the sensing area S of the sensed member 105, therefore the first position sensor 425a can detect the sensed member 105 and generate a first signal. The first signal is a low-level signal. The third position sensor 425b and the second position sensor 425c are both away from the sensing area S, therefore neither detects the sensed member 105. The third position sensor 425b generates a sixth signal, and the second position sensor 425c generates a fourth signal. The sixth and fourth signals are high-level signals. In some embodiments, the handle body 110 can even be... Figure 2B As shown, it is located approximately entirely outside the handle base 101, as long as the first position sensor 425a remains within the sensing area S of the sensed element 105.

[0057] When the operator pulls the position Figure 5C When the handle body 110 is in the position shown, the handle body 110 continues to move to the right relative to the handle base 101, and all position sensors of the position sensing device 120 move away from the sensing area S of the sensed element 105, so that the handle body 110 reaches the position shown. Figure 5D The second unfolded position is shown.

[0058] like Figure 5D As shown, the handle body 110 reaches the second extended position. The second support 112 of the handle body 110 is completely outside the handle base 101. At this time, the position sensing device 120 is also completely outside the handle base 101, and all position sensors are away from the sensing area S of the sensed element 105, so none of them detect the sensed element 105. The first position sensor 425a generates a second signal, the third position sensor 425b generates a sixth signal, and the second position sensor 425c generates a fourth signal. The second signal, the sixth signal, and the fourth signal are all high-level signals.

[0059] Therefore, when the handle body 110 is in different positions relative to the handle base 101, the three position sensors of the position sensing device 120 can generate different detection signals to indicate the position of the handle body 110. Correspondingly, the control device 150 can determine the position of the handle body 110 based on the detection signals emitted by the three position sensors of the position sensing device 120. In this embodiment, the control device 150 determines that the handle body 110 has reached the retracted position based on the third signal, and determines that the handle body 110 has reached the first extended position based on the first signal. The control device 150 can also determine that the handle body 110 has reached the second extended position based on the second, fourth, and sixth signals.

[0060] In this embodiment, the movement distance of the handle body 110 from the retracted position to the first extended position is relatively long. Therefore, the position sensing device 120 is provided with three spaced position sensors to ensure that none of the position sensors detect that the position of the sensed component is the second extended position of the handle body, rather than the position of the handle body between the retracted position and the first extended position. In some other embodiments, when the movement distance of the handle body 110 from the retracted position to the first extended position is short, the position sensing device 120 may also include only the first position sensor 425a and the second position sensor 425c.

[0061] Figures 6A-6C A simplified schematic diagram showing the relative positions of the handle seat 101 and the handle body 110 during movement of the handle body 110 in a handle system according to another embodiment of this application. Figures 5A-5D Similarly, in Figures 6A-6C The approximate value shown is Figures 1A-1B The handle system 100 is shown in the diagram with respect to the relative positions of the handle base 101 and the handle body 110 when viewed from the left. From this perspective, the handle body 110 moves from the inside out relative to the handle base 101. Figures 6A-6C The movement proceeds from left to right. Figures 6A-6C In the illustrated embodiment, the position sensing device 620 includes only two position sensors: a first position sensor 425a and a second position sensor 425c. The control device 150 determines that the handle body 110 has reached the first extended position based on the detection signal of the first position sensor 425a, determines that the handle body 110 has reached the retracted position based on the detection signal of the second position sensor 425c, and determines that the handle body 110 has reached the second extended position based on the combined detection signals of the first position sensor 425a and the second position sensor 425c.

[0062] Figure 6A The relative positions of the handle base 101 and the handle body 110 are shown when the handle body 110 is in the retracted position. Figure 6B The relative positions of the handle base 101 and the handle body 110 are shown when the handle body 110 is in the first extended position. Figure 6C The diagram shows the relative positions of the handle base 101 and the handle body 110 when the handle body 110 is in the second extended position. Table 2 shows the positions of the handle base 101 and the handle body 110. Figures 6A-6C During the process, the detection signals emitted by each position sensor of the position sensing device. In this embodiment, the detection signals include a first signal and a second signal emitted by the first position sensor 425a, and a third signal and a fourth signal emitted by the second position sensor 425c.

[0063] Table 2. Detection signals emitted by each position sensor like Figure 6A As shown, the handle body 110 is in the retracted position. At this time, the outermost second position sensor 425c of the position sensing device 120 is located in the sensing area S of the sensed element 105, so the second position sensor 425c can detect the sensed element 105 and generate a third signal. The first position sensor 425a is not located in the sensing area S, so neither of them detects the sensed element 105, and the first position sensor 425a generates a second signal. The third signal is a low-level signal, and the second signal is a high-level signal.

[0064] When handle 110 is arranged as follows Figure 6A As the arrow in the diagram moves from the retracted position to the first extended position, the second position sensor 425c gradually moves away from the sensing area S of the sensed element 105 until it reaches the position indicated by the arrow. Figure 6B The first unfolded position is shown.

[0065] like Figure 6B As shown, the handle 110 is in the first unfolded position. At this time, the leftmost first position sensor 425a of the position sensing device 620 is located in the sensing area S of the sensed member 105, so the first position sensor 425a can detect the sensed member 105 and generate a first signal. The second position sensor 425c is away from the sensing area S, so it does not detect the sensed member 105 and generates a fourth signal. The first signal is a low-level signal, and the fourth signal is a high-level signal.

[0066] When the operator pulls the position Figure 6B When the handle body 110 is in the position shown, the handle body 110 continues to move to the right relative to the handle base 101, and all position sensors of the position sensing device 620 move away from the sensing area S of the sensed element 105, and the handle body 110 reaches the position shown. Figure 6C The second unfolded position is shown.

[0067] like Figure 6C As shown, the handle body 110 reaches the second extended position. The second support 112 of the handle body 110 is completely outside the handle base 101. At this time, the position sensing device 620 is also completely outside the handle base 101, and all position sensors are away from the sensing area S of the sensed element 105, so none of them detect the sensed element 105. The first position sensor 425a generates a second signal, and the second position sensor 425c generates a fourth signal. Both the second signal and the fourth signal are high-level signals.

[0068] Therefore, when the handle body 110 is in different positions relative to the handle base 101, the two position sensors of the position sensing device 620 can generate different detection signals to indicate the position of the handle body 110. Correspondingly, the control device 150 can determine the position of the handle body 110 based on the detection signals emitted by the two position sensors of the position sensing device 620. In this embodiment, the control device 150 determines that the handle body 110 has reached the retracted position based on the third signal, and determines that the handle body 110 has reached the first extended position based on the first signal. The control device 150 can also determine that the handle body 110 has reached the second extended position based on the second and fourth signals.

[0069] Figures 5A-5D The illustrated embodiments and Figures 6A-6C The position sensing device includes a different number of position sensors compared to the illustrated embodiment. Figures 5A-5D In the illustrated embodiment, the movement distance of the handle body 110 from the retracted position to the first extended position is relatively long, while the sensing range S of the sensing element 105 is relatively small. Therefore, if the third position sensor 425b is not included, when the handle body 110 is in such a position... Figure 5B The positions shown and in the like Figure 5D When the position is shown, the control device receives only the second and fourth detection signals, which makes it impossible to identify the second deployed position. Those skilled in the art can set the appropriate number of Hall sensors based on the movement distance of the handle 110 from the retracted position to the first deployed position and the detection range of the Hall sensors.

[0070] Figure 7 A connection block diagram of the control device 150, position sensing device 120, drive device 160, and electronic lock device 170 is shown. Figure 7 As shown, the position sensing device 120, control device 150 and drive device 160 of the handle system 100 are communicatively connected to the electronic lock device 170 of the vehicle door 107, so that the control device 150 can receive the detection signal sent by the position sensing device 120, control the drive device 160 according to the received detection signal, and control the unlocking of the electronic lock device 170.

[0071] Figure 8 Show Figure 4A The illustrated embodiment shows a simplified circuit diagram of the detection circuit 831 on circuit board 422. Wherein, Figure 8 The dashed box in the figure represents the position sensing device 120, which includes the first position sensor 425a, the third position sensor 425b, and the second position sensor 425c.

[0072] like Figure 8As shown, the detection circuit 831 includes a power supply terminal 832 and a ground terminal 833. The power supply terminal 832 is communicatively connected to the control device 150 and connected to a power source through the control device 150 to provide voltage, such as 5V, to the detection circuit 831. The ground terminal 833 is grounded. The detection circuit 831 also includes a first circuit path 841, a second circuit path 842, and a third circuit path 843. The first circuit path 841, the second circuit path 842, and the third circuit path 843 are connected in parallel between the power supply terminal 832 and the ground terminal 833. A first position sensor 425a is connected in the first circuit path 841, a third position sensor 425b is connected in the second circuit path 842, and a second position sensor 425c is connected in the third circuit path 843.

[0073] The detection circuit 831 also includes three signal output terminals: signal output terminal 834, signal output terminal 835, and signal output terminal 836. These terminals are all communicatively connected to the control device 150 to output the respective detection signals generated by the first position sensor 425a, the third position sensor 425b, and the second position sensor 425c in the position sensing device 120 to the control device 150. In some embodiments, the first position sensor 425a and resistor 837a are connected in series in the first circuit path 841, and signal output terminal 834 is connected between the first position sensor 425a and resistor 837a to the first circuit path 841; the third position sensor 425b and resistor 837b are connected in series in the second circuit path 842, and signal output terminal 835 is connected between the third position sensor 425b and resistor 837b to the second circuit path 842; the second position sensor 425c and resistor 837c are connected in series in the third circuit path 843, and signal output terminal 836 is connected between the second position sensor 425c and resistor 837c to the third circuit path 843. The first circuit path 841, the second circuit path 842, and the third circuit path 843 are connected in parallel, with one end connected to the ground terminal 833 and the other end connected to the power supply terminal 832.

[0074] One end of the lamp module 438 is connected to the control device 150 via the LED port 837, and the other end is connected to the ground terminal 733. Thus, the control device 150 can controllably supply power to the lamp module 438 so that the handle system 100 can have a lighting effect.

[0075] Therefore, the circuit board 422 only needs to be connected to the control device 150 through the power supply terminal 832, signal output terminal 834, signal output terminal 835, signal output terminal 836 and LED port 837 to identify the position of the handle body 110 of the handle system 100 and control the light module 438 of the handle system 100.

[0076] Figure 9A structural block diagram of the control device for the handle system is shown. Figure 9 As shown, the control device 150 includes a bus 951, a processor 952, an input interface 953, an output interface 954, and a memory 955 containing a program 956. The various components of the control device 150, including the processor 952, input interface 953, output interface 954, and memory 955, are communicatively connected to the bus 951, enabling the processor 952 to control the operation of the input interface 953, output interface 954, and memory 955. Specifically, the memory 955 stores programs, instructions, and data, while the processor 952 reads programs, instructions, and data from the memory 955 and can write data to the memory 955. By executing the programs and instructions read from the memory 955, the processor 952 controls the operation of the input interface 953 and output interface 954.

[0077] like Figure 9 As shown, input interface 953 is communicatively connected to various signal output terminals and input commands of position sensing device 120 via connection line 957 to receive various parameters, such as detection signals from handle system 100 or input parameters from operator operation, and stores these parameters in memory 955. Output interface 954 is communicatively connected to drive device 160 of handle system 100, electronic lock device 170 of door 107, power supply terminal, and LED port via connection line 958. By executing program 956 in memory 955, control device 150 controls the movement of drive device 160 of handle system, and the opening or closing of electronic lock device 170 and light module 438. For example, input interface 953 is communicatively connected to signal output terminals 834, 835, and 836 of circuit board 422 to receive detection signals from handle system 100. Based on the received detection signals, the processor 952 generates corresponding control instructions based on the program 956 in the memory 955, including control instructions for the drive device 160, unlocking instructions for the electronic lock device 170, and on / off instructions for the lamp module 438. Through the output connection line 958, the control device 150 sends the generated control instructions externally via the power supply terminal 832 of the circuit board 422, the LED port 837, and the electronic lock device 170. Of course, those skilled in the art should understand that the signals received by the input interface 953 are not limited to detection signals, and the control instructions generated by the processor 952 are not limited to the aforementioned instructions.

[0078] Figure 10 Showing includes Figure 1A A schematic diagram of a vehicle with a handle system 100 is shown. Figure 10As shown, vehicle 1060 includes a door 107, an electronic locking device 170, and a handle system 100. The electronic locking device 170 is disposed on the door 107 for locking or unlocking the door 107. The handle system 100 is capable of controlling the electronic locking device 170 and / or the actuation device 160 based on the position of the handle body relative to the handle base.

[0079] Figure 11 A flowchart illustrating the method for controlling the handle system 100 is shown. Figure 11 As shown, the method for controlling the handle system 100 includes steps 1161, 1162, and 1163. In step 1161, the control device 150 detects the relative position of the sensed member 105 with respect to the position sensor 425. For example, the control device 150 detects whether the position sensor has entered the sensed area (S) of the sensed member 105, and the position sensor 425 generates a corresponding detection signal. Then, step 1162 is executed.

[0080] In step 1162, the control device 150 determines the position of the handle body relative to the handle base based on the detection signal obtained from the position sensor 425. Then, step 1163 is executed.

[0081] In step 1163, based on the position of the handle body relative to the handle base, the control device 150 controls the operation of the drive device 160 or the operation of the electronic lock device 170. For example, it controls the drive device 160 to stop retracting the handle body 110, stop unfolding the handle body 110, or controls the electronic lock device 170 to unlock.

[0082] Figure 12 The detailed flowchart of step 1162 is shown. Figure 12 As shown, step 1162 includes steps 1264, 1265, and 1266. In step 1264, when the first position sensor 425a detects the sensed member 105, it is determined that the handle body 110 has reached the first unfolded position relative to the handle base 101.

[0083] In step 1265, when the second position sensor 425c detects the sensed element 105, it is determined that the handle body 110 has reached the retracted position relative to the handle seat 101.

[0084] In step 1266, when none of the position sensors detect the sensed element 105, it is determined that the handle body 110 has reached the second unfolded position relative to the handle base 101.

[0085] Figure 13 The detailed flowchart of step 1163 is shown. Figure 13As shown, step 1163 includes steps 1367, 1368, and 1371. In step 1367, when the handle body 110 reaches the first unfolded position relative to the handle base 101, the control device 150 controls the drive device 160 to stop driving the handle body 110 to unfold.

[0086] In step 1368, when the handle body 110 reaches the retracted position relative to the handle seat 101, the control device 150 controls the drive device 160 to stop driving the handle body 110 to retract.

[0087] In step 1371, when the handle body 110 reaches the second unfolded position relative to the handle seat 101, the control device 150 controls the electronic lock device 170 to unlock.

[0088] The handle system of this application, by providing a position sensing device and a sensed element that work together on the handle base and handle body, can accurately indicate whether the handle body is in a retracted position, a first extended position, or a second extended position relative to the handle base. Based on the position of the handle body, the control device of the handle system can control the drive device so that the drive device stops driving the handle body when it reaches the retracted position and the first extended position, and the control device can control the electronic lock device to unlock when the handle body moves to the second extended position.

[0089] The handle system of this application does not require additional components on the drive device, such as additional counters to indicate whether the drive device drives the handle body to move into place, or additional microswitches that require mechanical touch to open or close to indicate the position of the handle body in order to control the electronic lock device to unlock. Therefore, it can eliminate the need for additional components that communicate with the control device.

[0090] The position sensing device of this application can be installed inside the handle body, and the sensing element is installed inside the handle base, which has good waterproof performance, durability, and higher reliability.

[0091] In some embodiments, the sensed element is a magnet, and the position sensing device includes at least two Hall sensors. Due to the size limitations of the handle body, the size and detection accuracy of the Hall sensors are more suitable for position detection in concealed handle systems. Based on the movement stroke of the handle body, the number of Hall sensors can also be reasonably set so that the Hall sensors can cover the entire movement stroke of the handle body.

[0092] Furthermore, since the position sensing device of this application integrates the circuit through a circuit board, it not only has good integration performance, but also allows additional functional modules such as LED modules to share a common ground terminal on the circuit board. Therefore, it can reduce the number of ports, simplify the wiring of the handle system, make the wiring neater, and make assembly more convenient.

[0093] Although this disclosure has been described in conjunction with examples of the embodiments outlined above, various alternatives, modifications, variations, improvements, and / or substantially equivalents, whether known or now or soon to be foreseen, will likely be apparent to those skilled in the art. Therefore, the examples of embodiments of this disclosure set forth above are intended to be illustrative rather than restrictive. Various changes can be made without departing from the spirit or scope of this disclosure. Therefore, this disclosure is intended to include all known or previously developed alternatives, modifications, variations, improvements, and / or substantially equivalents. The technical effects and problems described in this specification are exemplary rather than restrictive. It should be noted that the embodiments described in this specification may have other technical effects and may solve other technical problems.
