Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to a digital door opening control mechanism, a vehicle door and a vehicle. Background Art

[0002] Nowadays, the degree of automation of automobiles is getting higher and higher. For example, in announcement No. CN220790968U, the car doors are equipped with a driving mechanism that can drive the car doors to move actively. If the driving mechanism is switched to manual mode, the motor in the driving mechanism will engage with the worm gear to produce damping. When the door needs to be opened, the person will pull the door out. When the door is heavy or in an uphill opening state or a downhill closing state, the force transmitted to the person opening the door will be large, making it more difficult to open the door and the door opening and closing will be slow. If the door is light or in a downhill opening state or an uphill closing state, the acceleration of the door rotation will be large, and the door will open and close quickly, which will hit objects around the vehicle or cause the door itself to vibrate greatly, causing property damage. If a child or a smaller force is used to open the door, the damping provided by the motor is heavy, making it impossible to open the door. The above situations will result in inconsistent states of the occupants in opening the door, resulting in poor physical sensations for the occupants, poor feel of the door opening and closing, and an inability to provide a constant door opening and closing feel, reducing the user experience. Utility Model Content

[0003] The utility model aims to provide a digital door opening control mechanism, a vehicle door and a vehicle, so as to solve the problem in the prior art that different torques are required for door opening and the hand feeling is poor due to different positions of the vehicle or different weights of the door.

[0004] To achieve this purpose, the utility model adopts the following technical solutions: the utility model provides a digital door opening control mechanism, which is installed in the vehicle door and includes a digital drive component and an ECU. The digital drive component includes a drive member and a sensor. The drive member includes a motor, a socket and a worm. One end of the worm is rotatably installed on the frame, and the other end of the worm is inserted in the socket. The output end of the motor is arranged in the socket, and the output end is connected to the worm in a transmission manner; when the output end rotates, the worm is telescoped relative to the socket; a sensor is installed on the side of the worm close to the frame, and the sensor can detect the force value information of the telescopic movement of the worm. The sensor transmits the force value information to the ECU, and the ECU is electrically connected to the motor; when the force value information received by the ECU is less than the set value, the motor drives the output end to rotate and suppresses the movement of the worm, and when the force value information received by the ECU is greater than the set value, the motor drives the delivery end to rotate and drives the worm to move.

[0005] Preferably, the driving component includes a bracket, the motor is inverted on the bracket, the socket part is installed on the lower side of the motor, the socket part is fixed on the bracket, the ECU is installed on the lower side of the socket part, the ECU is installed on the bracket or the ECU is installed in the vehicle door.

[0006] Preferably, the sensor is ring-shaped and sleeved on the worm.

[0007] Preferably, the ECU and the sensor are connected via wire.

[0008] Preferably, the set value in the ECU is adjustable.

[0009] A vehicle door comprises the digital door opening control mechanism described above, and also comprises a door body, wherein a cavity is formed in the door body, and the digital door opening control mechanism is fixed in the cavity.

[0010] A vehicle comprises the vehicle door described above and also comprises a vehicle frame, the vehicle doors are rotatably mounted on both sides of the vehicle frame, and the worm is telescopically movably connected to the vehicle frame.

[0011] Beneficial effect: The force information of the worm is detected by the sensor. When the door moves slowly and the resistance felt by the passenger's hand is large, the force information is greater than the set value in the ECU. The motor will then assist in driving the worm to move through the output end, so that the worm and the door move in the same direction, reducing resistance and making it easier for passengers to open and close the door. If the sensor detects that the force information of the worm is less than the set value in the ECU and the door moves faster, the ECU will drive the drive motor to provide a force in the opposite direction of the worm, thereby suppressing the speed of the worm in the socket, increasing the resistance of the door movement, avoiding collisions caused by excessive door movement, reducing economic losses, protecting the digital door opening control mechanism in the door, and reducing the probability of damage. At the same time, the above process is automatically adjusted by the digital door opening control mechanism, without manual setting, which can save development costs.

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0016] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0018] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0019] Under the existing technology, cars are equipped with doors that can open and close automatically. However, when the automatic opening and closing function is turned off and the door is in manual mode, the driving component is in a closed state and the door cannot be moved normally using a small force. At the same time, the engagement between the worm and the motor drive end will generate resistance, which will further increase the force of opening and closing the door. At the same time, when the door is opened and closed manually with great force, it will generate large vibrations, which may damage the mechanism inside the door and make it impossible to open and close the door normally.

[0020] In order to solve the above problems, Figure 1 to Figure 2As shown, the utility model provides a digital door opening control mechanism, which is installed in the vehicle door, wherein the digital door opening control mechanism includes a digital driving component and an ECU, the ECU is a part of the control system in the digital door opening control mechanism, the digital driving component includes a driving member and a sensor 5, it should be particularly noted that the driving member and the sensor 5 are assembled as a whole, the driving member includes a motor 1, a socket 3 and a worm 2, one end of the worm 2 is rotatably mounted on the vehicle frame, the other end of the worm 2 is plugged into the socket 3, the output end of the motor 1 is arranged in the socket 3, and the output end is transmission-connected to the worm 2 The output end rotates, and the worm 2 is extended and retracted relative to the sleeve 3; a sensor 5 is installed on the side of the worm 2 close to the frame, and the sensor 5 can detect the force value information during the movement of the worm 2, that is, the damping formed by the door on the occupant's hand at this time. The motor 1 is integrated with a Hall sensor, wherein the Hall sensor mainly detects the rotation direction of the worm 2 around the vehicle body, so that the ECU can directly determine whether the door is in an open state or a closed state. At the same time, the Hall sensor also detects the rotation speed of the worm 2, so as to determine whether the door moves too fast. At the same time, the Hall sensor can also detect the acceleration of the rotation of the worm 2, such as Figure 2 As shown, the sensor 5 and the Hall sensor transmit all the information to the ECU. The ECU is electrically connected to the motor 1. The ECU controls the rotation of the motor 1 through an algorithm, and then adjusts the torque of opening and closing the door. The above-mentioned adjusted torque can continue to be fed back to the ECU. The ECU can detect in real time and dynamically adjust the opening and closing torque of the door. The ECU is usually installed in the door, independent of the digital drive components, so that the digital drive components can be flexibly replaced and adjusted according to the selection, and can adapt to different vehicle models.

[0021] The ECU stores the target value or target range of speed, acceleration and force information. When the force information received by the ECU is less than the set value, it means that the car door is in a fast-moving slamming state. When the door is manually opened, the worm 2 drives the motor 1, and the motor 1 can provide load, which means that the car door is light or the car door is in an uphill closing or downhill opening state. At this time, the worm 2 is quickly extended or retracted relative to the socket 3, and the car door has the risk of fast-moving collision. Starting the motor 1 by the ECU drives the output end to rotate to inhibit the movement of the worm 2, which is equivalent to applying a force in the opposite direction to the worm 2 along the axis of the worm 2. At this time, the external thrust is still greater than the force applied by the motor 1 to the worm 2, but the moving speed and acceleration of the worm 2 can be suppressed, thereby reducing the vehicle The speed of door rotation and the reverse trend of worm 2 provided by the output end can increase the damping of the door, provide a certain damping for the door, maintain the consistent texture of door opening and closing, avoid serious impact of the door, and reduce the probability of damage to parts inside the door; when the force value information received by the ECU is greater than the set value, the door moves slowly under the external thrust, and the motor 1 drives the conveying end to rotate and drives the worm 2 to move. At this time, the force applied by the motor 1 to the worm 2 is in the same direction as the external thrust, so that the speed of rotation of the worm 2 relative to the frame becomes faster, so that passengers with less strength can open and close quickly when opening and closing the door or when the door is closed downhill or opened uphill, making it easier for passengers to open and close, improving the passenger experience, and keeping the texture of vehicle door opening and closing unchanged.

[0022] The above-mentioned adjustment process automatically adjusts the torque required for door opening through the digital door opening control mechanism. The torque required for door opening can be monitored in real time through sensor 5. There is no need to manually calibrate the door opening force, thus saving development costs. The mechanism is used in the aftermarket and does not need to be adjusted to adapt to doors of different weights. Since the system adaptively controls the door opening torque, the door opening torque can be adjusted in real time regardless of whether the vehicle is in an uphill or downhill state, so that the occupants' feel of opening and closing the door remains consistent, and it is insensitive to deviations in the production of the mechanism, thereby reducing the factory's production defect rate.

[0023] If the sensor 5 detects that the force of opening and closing the door is too large, the above signal will be transmitted to the ECU, and the ECU will increase the rotation torque of the motor 1 to provide a strong reaction force to the worm 2, so that the door stops moving under the drive of the reverse force of the worm 2, avoiding large impact on the door and reducing the probability of damage to the door.

[0024] The driving component of the utility model includes a bracket 4, the motor 1 is inverted on the bracket 4, the sleeve part 3 is installed on the lower side of the motor 1, and the sleeve part 3 is fixed on the bracket 4. In addition, the ECU of the utility model can also be installed on the lower side of the sleeve part 3, and the ECU is installed on the bracket 4.

[0025] By integrating the bracket 4 at the position of the socket part 3, the digital drive components and the ECU can be fully integrated on the bracket 4, which is convenient for integrated processing on the production line. Furthermore, the digital door opening control mechanism can be directly installed in the vehicle door in one set of processes on the production line, saving installation steps and shortening the production cycle.

[0026] The sensor 5 is ring-shaped. It should be noted that the shape of the sensor 5 is not necessarily ring-shaped. Other types of sensors can also be used. The sensor 5 of the utility model can detect force value information. At the same time, a Hall sensor is integrated in the motor 1. The speed, direction and acceleration of the door movement can be detected by the Hall sensor. The sensor 5 is sleeved on the worm 2, which makes it difficult for the sensor 5 to fall off, making the digital door opening control mechanism of the utility model more reliable.

[0027] The wired connection between the ECU and the sensor 5 can make the force value information captured by the sensor 5 more stable during the transmission process. At the same time, the ECU and the sensor 5 can be transmitted via wireless signals, which can reduce the amount of wiring harnesses and make the assembly process simpler.

[0028] The set value in the ECU in the utility model is adjustable, and the damping of the door can be adjusted in real time through the ECU, or the damping in the ECU can be adjusted in real time through the central control screen in the car.

[0029] The vehicle door comprises a door body, a cavity is formed in the door body, and a digital door opening control mechanism is fixed in the cavity. The utility model can be applied to a vehicle door that is opened by rotation, and can also be applied to a vehicle door that is opened by sliding, and a tailgate of a vehicle.

[0030] The above-mentioned doors are installed on both sides of the vehicle frame, and the doors are rotatably installed on both sides of the frame. The worm gear 2 is rotatably connected to the frame. The ECU can be installed in the door, or integrated on the bracket 4, and electrically connected to the central control screen. The occupant can set the force of the door switch through the hollow screen, and the ECU can also make real-time adjustments according to the damping of the door switch.

[0031] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
