Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment, and in particular to a hinge assembly, a split door system, and a vehicle. Background Technology

[0002] Vehicles typically feature split doors for opening or closing at least a portion of the vehicle body. Related technologies usually employ two actuators to control the movement of the first and second doors respectively. These actuators integrate angle sensors, which detect the position of the corresponding door based on the angle of rotation of the actuator's motor shaft. The control unit then sends commands to the actuators to control the movement of the corresponding door based on the position measured by the angle sensors. However, the actuator structure in these technologies is relatively complex, and the angle sensors are difficult to maintain. Therefore, simplifying the actuator structure has become a pressing technical problem. Utility Model Content

To this end, one objective of this invention is to provide a hinge assembly in which a sensor for detecting the position of the vehicle door is separately set on a hinge bracket fixed to the vehicle body, and the actuator is set separately from the sensor.

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] The following is for reference. Figures 1-10 A hinge assembly according to an embodiment of the present invention is described.

[0039] Reference Figures 4-7 According to a first aspect embodiment of the present invention, the hinge assembly includes two hinge brackets rotatably connected and a sensor, one of which is fixed to the vehicle body and the other is fixed to the vehicle door. The sensor is disposed on the hinge bracket fixed to the vehicle body and is used to detect the position of the vehicle door.

[0040] The sensor is mounted on a hinged bracket fixed to the vehicle body, which allows the sensor to be located near the rotating connection between the door and the vehicle body. This shortens the distance between the sensor and the door, improving the accuracy of the door position information detected by the sensor. Furthermore, compared to integrating the sensor into the driver, setting the sensor separately on the hinged bracket fixed to the vehicle body allows for the detection of the door position while simplifying the driver structure and facilitating sensor maintenance or replacement.

[0041] According to the hinge assembly of this utility model embodiment, by separately setting the sensor for detecting the position of the car door and placing it on the hinge bracket fixed to the car body, and setting the driver and the sensor separately, compared with integrating the sensor and the driver, this can simplify the structure of the driver and facilitate the maintenance or replacement of the sensor.

[0042] Reference Figures 4-7 According to some embodiments of this utility model, the sensor is a micro switch. The sensor has a first state and a second state, which are different. One of the first state and the second state is in a conducting state and the other is in a disconnected state. The micro switch includes a stationary contact 322 and a moving spring 321. When the moving spring 321 is in contact with the stationary contact 322, the micro switch is in a conducting state; when the moving spring 321 is separated from the stationary contact 322, the micro switch is in a disconnected state. By using a micro switch as the sensor, the position information of the vehicle door can be detected more accurately by observing the state of the sensor.

[0043] When the sensor is in the first state, the door abuts against the sensor's movable spring 321, causing the movable spring 321 to contact the stationary contact 322 and conduct. When the sensor is in the second state, the door separates from the sensor's movable spring 321, causing the movable spring 321 to separate from the stationary contact 322. When the door rotates to a certain angle, the door abuts against the sensor's movable spring 321, and the door can apply a certain force to the sensor's movable spring 321, causing the movable spring 321 to undergo elastic deformation and contact the stationary contact 322, thereby turning the microswitch on and thus putting the sensor in the first state. When the door moves to other angles, such as when the door moves to the collision area 1b, the door separates from the sensor's movable spring 321. At this time, the movable spring 321 separates from the stationary contact 322 due to its own elastic force, causing the microswitch to be off, thus putting the sensor in the second state.

[0044] Reference Figures 7-10 The hinge bracket includes a mounting plate 1143, two hinge plates 1144, and a rotating shaft 1145. The mounting plate 1143 is connected to the vehicle body. The two hinge plates 1144 are connected to the left and right sides of the mounting plate 1143. The rotating shaft 1145 extends in the left and right direction, and the left and right ends of the rotating shaft 1145 are respectively connected to the two hinge plates 1144. The sensor is installed on one of the hinge plates 1144, which can make the sensor located on one side of the hinge bracket in the left and right direction. This facilitates the sensor to detect the position information of the door while avoiding interference between the sensor and the door, so that the door can move more smoothly around its own rotation axis.

[0045] Reference Figures 7-10According to some embodiments of this utility model, a support plate 1146 is provided on the hinge bracket, and the sensor is supported on the upper surface of the support plate 1146. The support plate 1146 can serve as the basic carrier of the sensor, providing support for the sensor. During the process of assembling the sensor to the hinge bracket, the support plate 1146 can also guide and position the sensor, ensuring that the sensor is accurately positioned on the hinge bracket.

[0046] Alternatively, the sensor can be fixed to the hinge bracket with fasteners, which makes the connection between the sensor and the hinge bracket simple and highly stable.

[0047] Reference Figures 7-10 According to some embodiments of this utility model, the sensor and the hinge bracket are detachably connected, which facilitates the maintenance or replacement of the sensor.

[0048] Reference Figures 1-4 According to a second aspect embodiment of the present invention, a split-type vehicle door system 1a includes a vehicle door, a hinge assembly, a first driver 13, a second driver 23, a first control unit 31, and a second control unit 33. The vehicle door includes a first door 11 and a second door 21. Both the first door 11 and the second door 21 are adapted to be rotatably connected to the vehicle body. For example, during the process of the vehicle door moving to the open position, the first door 11 and the second door 21 move away from each other, and during the process of the vehicle door moving to the closed position, the first door 11 and the second door 21 move closer to each other.

[0049] There are two hinge assemblies: a first hinge assembly 114 and a second hinge assembly 214. The sensor in the first hinge assembly 114 is a first sensor 32, which is used to detect the position information of the first door 11. The sensor in the second hinge assembly 214 is a second sensor, which is used to detect the position information of the second door 21. The first hinge assembly 114 is used to connect the first door 11 and the vehicle body, and the second hinge assembly 214 is used to connect the second door 21 and the vehicle body. The first actuator 13 is connected to the first door 11 to drive the first door 11 to move, and the second actuator 23 is connected to the second door 21 to drive the second door 21 to move. The first control unit 31 is electrically connected to the first actuator 13 and the second sensor, and the second control unit 33 is electrically connected to the second actuator 23 and the first sensor 32.

[0050] The first control unit 31 can control the movement of the first door 11 via the first driver 13 based on the position information of the second door 21 measured by the second sensor, thereby effectively avoiding a collision between the first door 11 and the second door 21. The second control unit 33 can control the movement of the second door 21 via the second driver 23 based on the position information of the first door 11 measured by the first sensor 32, thereby effectively avoiding a collision between the first door 11 and the second door 21.

[0051] For example, the first actuator 13 and the first control unit 31 are electrically connected via a first wiring harness 116, and the first control unit 31 and the second sensor are electrically connected via a third wiring harness. The first control unit 31 can control the action of the first actuator 13 based on the position information of the second door 21 measured by the second sensor, thereby controlling the movement of the first door 11, which can effectively prevent the first door 11 from colliding with the second door 21. The second actuator 23 and the second control unit 33 are electrically connected via a second wiring harness 215, and the second control unit 33 and the first sensor 32 are electrically connected via a fourth wiring harness. The second control unit 33 can control the action of the second actuator 23 based on the position information of the second door 21 measured by the first sensor 32, thereby controlling the movement of the second door 21, which can effectively prevent the first door 11 from colliding with the second door 21. For example, when the second door 21 is in the open position, the first control unit 31 can control the movement state of the first driver 13 based on the position information of the second door 21 measured by the second sensor, thereby controlling the movement of the first door 11 to effectively avoid a collision between the first door 11 and the second door 21.

[0052] Furthermore, compared to integrating the first sensor 32 into the first driver 13, setting the first sensor 32 separately and placing it on the hinge bracket fixed to the vehicle body can not only realize the function of the first sensor 32 detecting the position of the first door 11, but also simplify the structure of the first driver 13 and facilitate the maintenance or replacement of the first sensor 32.

[0053] Correspondingly, compared to integrating the second sensor into the second driver 23, by setting the second sensor separately and placing it on the hinge bracket fixed to the vehicle body, the second driver 23 can be simplified in structure while realizing the function of the second sensor detecting the position of the second door 21, and the maintenance or replacement of the second sensor can also be facilitated.

[0054] Optionally, the split door system 1a also includes a first door lock and a second door lock, the first door lock being used to cooperate with the first door 11 and the second door lock being used to cooperate with the second door 21.

[0055] The first door lock includes a first latch 111, a first lock body 112, a first switch 113, and a first cable. The first latch 111 cooperates with the first lock body 112. The first switch 113 controls the connection or disconnection between the first latch 111 and the first lock body 112. The first cable is located between the first switch 113 and the first lock body 112. One of the first latch 111 and the first lock body 112 is installed on the vehicle body, and the other of the first latch 111 and the first lock body 112 is installed on the first door 11. When the first door 11 is in the closed position, the cooperation of the first latch 111 and the first lock body 112 enables a stable connection between the first door 11 and the vehicle body, allowing the first door 11 to be held more stably in the closed position.

[0056] The second door lock includes a second latch 211, a second lock body 212, a second switch 213, and a second cable 217. The second latch 211 cooperates with the second lock body 212. The second switch 213 controls the connection or disconnection between the second latch 211 and the second lock body 212. The second cable 217 is located between the second switch 213 and the second lock body 212. One of the second latch 211 and the second lock body 212 is installed on the vehicle body, and the other of the second latch 211 and the second lock body 212 is installed on the second door 21. When the second door 21 is in the closed position, the cooperation of the second latch 211 and the second lock body 212 enables a stable connection between the second door 21 and the vehicle body, allowing the second door 21 to be held more stably in the closed position.

[0057] According to the split-type car door system 1a of this utility model embodiment, the first control unit 31 is electrically connected to the second sensor, and can control the movement of the first car door 11 in a timely manner according to the position of the second car door 21 measured by the second sensor. The second control unit 33 is electrically connected to the first sensor 32, and can control the movement of the second car door 21 in a timely manner according to the position of the first car door 11 measured by the first sensor 32. This can effectively avoid collision between the first car door 11 and the second car door 21. Furthermore, by setting the sensor for detecting the car door position separately and setting it on the hinge bracket fixed to the car body, and setting the driver and the sensor separately, compared with integrating the sensor and the driver, the structure of the driver can be simplified, and the maintenance or replacement of the sensor can be facilitated.

[0058] Reference Figures 1-4According to some embodiments of the present invention, both the first sensor 32 and the second sensor have a first state and a second state, which are different. The first sensor 32 is configured to be in the first state when the first door 11 is located in the collision area 1b and in the second state when the first door 11 is located in the first safety area; the second sensor is configured to be in the first state when the second door 21 is located in the collision area 1b and in the second state when the second door 21 is located in the second safety area.

[0059] When the first sensor 32 is in the first state, it indicates that the first door 11 is located in the collision area 1b. If the second door 21 moves at this time, it may collide with the first door 11. By controlling the second door 21 to remain stationary through the second control unit 33, the collision between the first door 11 and the second door 21 can be effectively avoided. When the first sensor is in the second state, it indicates that the first door 11 is located in the first safe area. At this time, the second control unit 33 controls the movement of the second door 21, which can effectively avoid the collision between the first door 11 and the second door 21.

[0060] When the second sensor is in the first state, it indicates that the second door 21 is located in the collision area 1b. If the first door 11 moves at this time, it may collide with the second door 21. By controlling the first door 11 to remain stationary by the first control unit 31, the collision between the second door 21 and the first door 11 can be effectively avoided. When the second sensor is in the second state, it indicates that the second door 21 is located in the second safe area. At this time, the first control unit 31 controls the first door 11 to move, which can effectively avoid the collision between the second door 21 and the first door 11.

[0061] The first control unit 31 and the second control unit 33 can obtain the position information of the door corresponding to the sensor relatively accurately according to the state of the corresponding sensor, and then control the movement of the door according to the position information of the door, which can effectively avoid the collision between the first door 11 and the second door 21.

[0062] It should be explained that the opening positions of the first door 11 and the second door 21 include the maximum opening position, which refers to the position of the first door 11 or the second door 21 after rotating the maximum angle along the set path from the closed position.

[0063] The first door 11 has a first critical position, which (for example, can be referred to as g2 in the figure) is located in the closed position of the first door 11 (for example, can be referred to as g2 in the figure). Figure 1 Between g1) and the maximum opening position of the first door 11, when the first door 11 is located between the first critical position and the maximum opening position of the first door 11, the first door 11 is located in the first safe area.

[0064] Accordingly, the second door 21 has a second critical position (for example, refer to...). Figure 1 In s2), the second critical position of the second door 21 is located in the closed position of the second door 21 (for example, refer to s2). Figure 1 Between s1) and the maximum open position of the second door 21, when the second door 21 is located between the second critical position and the maximum open position of the second door 21, the second door 21 is located in the second safe area, and the area swept by the second door 21 during the process of moving from the closed position to the second critical position constitutes the collision area 1b.

[0065] For example, the first door position signal includes a first avoidance signal, a first safety signal, and a first transition signal. The first avoidance signal is the signal emitted by the first sensor 32 when it is in a first state, at which time the first door 11 is located in the collision area 1b. The first safety signal is the signal emitted by the first sensor 32 when it is in a second state, at which time the first door 11 is located in the first safety area. The first transition signal is the signal emitted by the first sensor 32 when it switches between the first state and the second state, at which time the first door 11 is located at a first critical position between the collision area 1b and the first safety area. When the first door 11 is located at the first critical position, the state of the first sensor 32 changes, causing the signal emitted by the first sensor 32 to change. Therefore, the signal emitted by the first sensor 32 is the first transition signal.

[0066] When the first door 11 is in different positions, the corresponding first door position signal is different. Thus, when the second control unit 33 receives the door opening and closing command, the second control unit 33 can determine whether the first door 11 is in the collision area 1b or the first safety area based on the first avoidance signal, the first safety signal or the first jump signal emitted by the first sensor 32, and control the movement state of the second drive 23 to effectively avoid the collision between the first door 11 and the second door 21.

[0067] Accordingly, the second door position signal includes a second avoidance signal, a second safety signal, and a second transition signal. The second avoidance signal is emitted when the second sensor is in the first state, at which time the second door 21 is located in the collision area 1b. The second safety signal is emitted when the second sensor is in the second state, at which time the second door 21 is located in the second safety area. The second transition signal is emitted when the second sensor switches between the first and second states, at which time the second door 21 is located at the second critical position between the collision area 1b and the second safety area. When the second door 21 is located at the second critical position, the state of the second sensor changes, causing the signal emitted by the second sensor to change. Therefore, the signal emitted by the second sensor is the second transition signal.

[0068] When the second door 21 is in different positions, the corresponding second door position signal is different. Thus, when the first control unit 31 receives the door opening and closing command, the first control unit 31 can determine whether the second door 21 is in the collision area 1b or the second safety area based on the second avoidance signal, the second safety signal or the second jump signal emitted by the second sensor, and control the movement state of the first driver 13 to effectively avoid the collision between the first door 11 and the second door 21.

[0069] For example, if the second sensor detects that the second door 21 is located in the collision area 1b, the signal received by the first control unit 31 is the second avoidance signal. At this time, the first control unit 31 can control the first door 11 to stop moving via the first driver 13 to avoid the first door 11 from colliding with the second door 21.

[0070] For example, if the first sensor 32 detects that the first door 11 is located in the collision area 1b, the signal received by the second control unit 33 is the first avoidance signal. At this time, the second control unit 33 can control the second door 21 to stop moving via the second driver 23 to avoid the first door 11 from colliding with the second door 21.

[0071] Reference Figures 7-10 According to some embodiments of the present invention, the two hinge brackets of the first hinge assembly 114 are a first hinge bracket 1141 and a second hinge bracket 1142. The first hinge bracket 1141 is fixed to the vehicle body, and the second hinge bracket 1142 is fixed to the first door 11. The first sensor 32 is disposed on the first hinge bracket 1141. By rotating the second hinge bracket 1142 relative to the first hinge bracket 1141, the second hinge bracket 1142 can drive the first door 11 to move, thereby realizing the rotatable connection between the first door 11 and the vehicle body. Furthermore, by disposing the first sensor 32 on the first hinge bracket 1141, the first sensor 32 can be located near the rotatable connection between the first door 11 and the vehicle body, thereby improving the accuracy of the position information of the first door 11 detected by the first sensor 32.

[0072] The two hinge brackets of the second hinge assembly 214 are a third hinge bracket and a fourth hinge bracket. The third hinge bracket is fixed to the vehicle body, and the fourth hinge bracket is fixed to the second door 21. The second sensor is located on the third hinge bracket. By rotating the fourth hinge bracket relative to the third hinge bracket, the fourth hinge bracket can drive the second door 21 to move, thereby realizing the rotatable connection between the second door 21 and the vehicle body. Furthermore, by placing the second sensor on the third hinge bracket, the second sensor can be located near the rotatable connection between the second door 21 and the vehicle body, thereby improving the accuracy of the position information of the second door 21 detected by the second sensor.

[0073] Reference Figure 1 According to some embodiments of this utility model, the first door 11 and the second door 21 are arranged vertically, with the second door 21 located below the first door 11. When both the first door 11 and the second door 21 are in the closed position, the lower end of the first door 11 covers the outer side of the upper end of the second door 21. When the first door 11 and the second door 21 are in the closed position, the lower end of the first door 11 covering the outer side of the upper end of the second door 21 enhances the overall sealing effect of the doors, reducing or preventing dust or water from entering the vehicle interior through the gap between the first door 11 and the second door 21.

[0074] For example, when the first door 11 and the second door 21 are in the closed position, the lower sidewall of the first door 11 forms a first mating sidewall 115, and the upper sidewall of the second door 21 forms a second mating sidewall 216. The first mating sidewall 115 and the second mating sidewall 216 are arranged opposite to each other, and both the first mating sidewall 115 and the second mating sidewall 216 extend downward at an angle from the inside to the outside, so that at least a portion of the first mating sidewall 115 is located outside the second mating sidewall 216. This can enhance the sealing effect of the doors and reduce the possibility of dust or water entering the vehicle interior through the gap between the first door 11 and the second door 21.

[0075] Wherein, at least a portion of the first mating sidewall 115 is located outside the second mating sidewall 216, which may include the following situations: for example, a portion of the first mating sidewall 115 may be located outside the second mating sidewall 216; or, for another example, the entire first mating sidewall 115 may be located outside the second mating sidewall 216.
