[0013] According to some embodiments of the present application, the front hatch assembly for a vehicle further includes: a linkage hinge, wherein the linkage hinge and the driving rod are symmetrically arranged on both sides of the hatch, and the linkage hinge hinges connect the hatch to the hatch body.

[0014] The following is a brief description of a vehicle according to an embodiment of the present application.

[0015] The vehicle according to the embodiment of the present application includes a vehicle body and a front hatch assembly of any of the above embodiments, and the front hatch assembly is arranged on the vehicle body. Since the vehicle according to the present embodiment is provided with the front hatch assembly of any of the above embodiments, the vehicle according to the present application has a front hatch assembly with high driving convenience. When the front cabin storage box needs to be used to place or take out items, the front hatch can be opened or closed by operating a control device such as a button or a smart key in the vehicle, thereby avoiding the problems of automatic rebound caused by failure of the hydraulic struts of the traditional mechanical opening and closing structure in low temperature environments such as winter, and false touch of the existing mechanical buckle. The front hatch assembly can operate stably and reliably, reducing the troubles and inconveniences that the user may encounter during the operation, providing the user with a more comfortable and convenient use experience, and improving the user's satisfaction with the vehicle; at the same time, since at least part of the electronic control housing is accommodated in the interior of the drive rod, the space inside the vehicle is effectively saved, and the front hatch assembly makes the spatial layout of the front cabin area more compact, providing more possibilities for the installation and arrangement of other components of the vehicle, and also providing the user with a larger front cabin storage space, meeting the user's demand for vehicle storage space.

[0016] According to some embodiments of the present application, the vehicle further includes: a kick sensor, wherein the kick sensor is disposed on a side of the vehicle body close to the front door assembly, and the kick sensor is disposed at the bottom of the vehicle body.

[0017] The following briefly describes a control method for a front door assembly according to an embodiment of the present application.

[0018] According to the control method for the front door assembly of the embodiment of the present application, the method includes: controlling the drive motor to drive the hatch cover to close after obtaining the front hatch cover closing command; controlling the triggering of the anti-pinch function of the front door after the drive motor torque reaches a first preset value, and starting compensation for the opening angle of the front hatch cover according to the motor speed and adjusting the first preset value.

[0019] According to the control method for the front door assembly of the embodiment of the present application, when the front hatch closing command is obtained, the drive motor is started. Since the drive motor is the actuator that drives the hatch to open and close, the drive motor is operated to convert electrical energy into mechanical energy, thereby pulling the drive rod to move the hatch in the closing direction.

[0020] During the operation of the drive motor, when the torque reaches a first preset value, the control triggers the anti-pinch function of the front hatch. When the torque of the drive motor reaches a certain level, it means that the hatch has encountered an obstacle during the closing process. For example, there may be foreign objects sandwiched between the hatch and the front cabin body. If the hatch continues to be forcibly closed at this time, it may not only damage the hatch and foreign objects, but also cause damage to related parts of the vehicle and even cause harm to personnel. Therefore, by setting the torque to reach the first preset value to trigger the anti-pinch function, abnormal situations can be detected in time to ensure safe use.

[0021] At the same time, the opening angle of the front hatch cover is started and compensated according to the motor speed and the first preset value is adjusted. The motor speed can reflect the actual movement state of the hatch cover. If the motor speed is abnormal, it may mean that the movement of the hatch cover is affected, such as resistance changes. By monitoring the motor speed, the opening angle of the hatch cover can be understood in real time. When it is found that the motor speed is inconsistent with expectations, the opening angle of the front hatch cover is started and compensated, which can ensure that the hatch cover can reach the predetermined position and avoid inaccurate closing position of the hatch cover due to various interference factors. Moreover, adjusting the first preset value according to the actual operation situation can make the triggering condition of the anti-pinch function more in line with the actual use scenario. With the changes in the vehicle use environment, such as temperature, humidity, etc. affecting the performance of components, or the components themselves are worn with the increase of use time, the original first preset value is no longer the most suitable standard for triggering the anti-pinch function. By dynamically adjusting the first preset value, the system can better adapt to different working conditions, improve the accuracy and reliability of the control of the entire front hatch door assembly, and ensure that the front hatch door can operate safely and accurately under various conditions.

[0044] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0045] Reference below Figure 1-Figure 5A front hatch door assembly 100 for a vehicle according to an embodiment of the present application is described.

[0046] According to an embodiment of the present application, a front hatch door assembly 100 for a vehicle includes a front hatch body 1, a hatch cover 2, a driving rod 3, a driving motor and an electronic control housing, wherein the front hatch body 1 is suitable for being installed on a vehicle body 10, a front hatch cavity 11 is formed in the front hatch body 1, the hatch cover 2 is openably and closably arranged on the front hatch body 1 to open or close the front hatch cavity 11, one end of the driving rod 3 is hingedly connected to the front hatch body 1, and the other end of the driving rod 3 is connected to the hatch cover 2, the driving rod 3 is telescopically arranged to drive the hatch cover 2 to open or close the front hatch body 1, the driving motor is arranged inside the driving rod 3 and is suitable for driving the telescopic body of the driving rod 3, the electronic control housing 4 is formed with a supporting plate body for installing an electronic control circuit, and at least one side wall of the supporting plate body in the thickness direction is formed with a mounting wall 43 for arranging an electronic control board 44; wherein the electronic control housing 4 is arranged on the driving rod 3 and is integrated with the driving rod 3, at least a part of the electronic control housing 4 is accommodated inside the driving rod 3, and the electronic control board 44 is used to connect an external power supply to the driving motor and control the operation of the driving motor.

[0047] In related technologies, the degree of automobile intelligence continues to deepen, and users' dependence on the functions of the front cabin storage box has significantly increased. However, the pain points exposed by the traditional mechanical opening and closing structure are becoming increasingly severe. The existing mechanical buckles may be accidentally touched, and the hydraulic struts are prone to automatic rebound due to failure in low temperature environments such as winter, which cannot meet the needs of users for frequent use of the front cabin storage box.

[0048] According to the front hatch assembly 100 for a vehicle in the embodiment of the present application, the electric control housing 4 is formed with a supporting plate body for installing an electric control board 44, and is integrated with the drive rod 3, and is partially accommodated in the drive rod 3. The electric control board 44 is responsible for connecting the external power supply and the drive motor and controlling the motor to work, so that the electric control system and the drive system are closely integrated, which can ensure that the power supply is stably supplied to the drive motor and ensure continuous power; the electric control board 44 can receive control signals such as those sent by buttons in the car, smart keys, etc., which can be that the opening button in the car is pressed, and the signal is instantly transmitted to the electric control board 44, and the electric control board 44 immediately processes and controls the operation of the drive motor, and adjusts the extension speed and stroke of the drive rod 3. The hatch cover 2 can be opened or closed at the speed and angle expected by the user, meeting the convenience demand of the front cabin storage box; one end of the driving rod 3 is hinged to the front cabin body 1, and the other end is connected to the hatch cover 2 and is retractable, so that the driving rod 3 can directly provide power for the opening and closing of the hatch cover 2. The driving motor is built into the driving rod 3 to avoid the need for an additional transmission device to connect the driving components of the traditional external motor, which has power transmission loss and delay. The built-in motor can directly drive the driving rod 3 and respond to the control signal quickly. The motor operates quickly to drive the driving rod 3 to retract and retract, driving the hatch cover 2 to move quickly, thereby improving the response speed. There is no need to wait for a long time for the hatch cover 2 to open and close, and the convenience is significantly improved.

[0049] At the same time, since at least part of the electronic control housing 4 is accommodated inside the driving rod 3, the space inside the vehicle is effectively saved. Within the limited space of the vehicle, the front door assembly 100 makes the spatial layout of the front cabin area more compact and reasonable, and provides more possibilities for the installation and arrangement of other components of the vehicle. At the same time, it also provides a larger front cabin storage space, meeting the user's demand for vehicle storage space.

[0050] According to some embodiments of the front hatch assembly 100 for a vehicle of the present application, the driving rod 3 includes a cylinder 31 and an outer sleeve 32. A mounting cavity 311 is formed inside the cylinder 31. The driving motor is arranged in the mounting cavity 311. The outer sleeve 32 is drivingly connected to the output shaft of the driving motor and moves in an extension direction relative to the cylinder 31 under the drive of the driving motor. A lower ball socket 33 is provided at one end of the cylinder 31, and the ball socket is used to connect to the body 10 of the vehicle. An upper ball socket 34 is provided at one end of the outer sleeve, and the upper ball socket 34 is connected to the hatch 2.

[0051] The motor is built into the cylinder 31, and the structural space of the drive rod 3 itself is utilized, avoiding the need to open up a separate external installation space for the motor. The available space in the front cabin is increased, providing more space for the layout of other components, optimizing the layout of the entire front cabin, and also contributing to the overall lightweight design of the vehicle, because reducing the additional space occupation means that some unnecessary structural weight can be reduced.

[0052] One end of the cylinder 31 is connected to the vehicle body 10 through the lower ball socket 33, and one end of the outer sleeve is connected to the hatch cover 2 through the upper ball socket 34. The ball socket can rotate relative to each other in multiple directions, so that the hatch cover 2 can better adapt to the structure and movement of the vehicle body 10 when opening and closing. When the vehicle is driving, the vehicle body 10 will produce a slight deformation or displacement due to factors such as road conditions. The lower ball socket 33 and the upper ball socket 34 can rotate at the connection points with the vehicle body 10 and the hatch cover 2 respectively, ensuring that the hatch cover 2 is stably connected to the vehicle body 10 without affecting the normal opening and closing of the hatch cover 2, thereby improving the adaptability and reliability of the front hatch door assembly 100 under different working conditions; at the same time, it avoids the traditional rigid In the non-linear connection mode, the hatch cover 2 and the vehicle body 10 move asynchronously, which can easily cause a large stress concentration at the connection point, resulting in premature wear or even damage to the connection components. The ball and socket connection can evenly disperse the stress generated by the movement of the hatch cover 2 and the deformation of the vehicle body 10 through multi-directional relative rotation. When the hatch cover 2 is closed and subjected to lateral force, the ball socket can rotate to adjust the direction of the force to avoid excessive stress in a certain local area, thereby extending the service life of the connection components, reducing maintenance costs, and improving the stability and safety of the entire front door assembly 100, reducing safety hazards such as accidental opening of the hatch cover 2 due to damage to the connection components.

[0053] According to some embodiments of the present application, a front door assembly 100 for a vehicle, the electronic control housing 4 includes a first support plate 41 and a second support plate 42, wherein the first support plate 41 extends in a cross section perpendicular to the installation space and is configured to be at least two support plates spaced apart in the extension direction of the cylinder 31, and the second support plate 42 is disposed between two adjacent first support plates 41 and connects the two adjacent first support plates 41; wherein the first support plate 41 and the second support plate 42 are configured to be support plate bodies, and a mounting wall 43 for mounting an electronic control board 44 is formed on the surfaces of the first support plate 41 and the second support plate 42.

[0054] A plurality of first support plates 41 are arranged at intervals in the extension direction of the cylinder 31 to build a frame structure. When the vehicle vibrates or bumps while driving, or the front door assembly 100 is impacted by external force, these first support plates 41 distributed at intervals can disperse the force to multiple support points to avoid excessive pressure on a single point, thereby improving the stability of the overall structure, ensuring that the electric control housing 4 is not easily deformed under complex working conditions, and providing a reliable installation foundation for the internal electric control board 44; the support plate body composed of the first support plate 41 and the second support plate 42 has a mounting wall 43 formed on its surface, which greatly expands the installation area of ​​the electric control board 44. The surfaces of multiple support plates can be used to increase the installation space. When the electric control board 44 is actually arranged, it can be flexibly installed according to the size and layout requirements of different functional modules, and can adapt to electric control boards 44 of different specifications and shapes, thereby improving the compatibility of the electric control housing 4 with various types of electric control boards 44, facilitating the design and integration of the electric control system, and reducing costs.

[0055] According to some embodiments of the present application, the front hatch assembly 100 for a vehicle is structured as a plurality of second support plates 42 , which are spaced apart on the periphery of the first support plate 41 , and the interiors of the plurality of second support plates 42 define a receiving cavity 45 .

[0056] Multiple second support plates 42 are evenly distributed around the first support plate 41, which can effectively disperse external forces from different directions. The second support plates 42 can disperse the impact force to the entire frame structure, avoid structural damage caused by local stress concentration, enhance the overall deformation resistance of the electronic control housing 4, ensure that it can remain stable in a complex working environment, and provide reliable protection for the internal electronic control components; the structure of multiple second support plates 42 can facilitate the arrangement of wires and cables. In the front door assembly 100 of the vehicle, various electronic control components usually need to be connected, and the arrangement of wires and cables is relatively complicated. By utilizing the space between the second support plates 42, the wires and cables can be neatly arranged in the accommodating cavity 45, avoiding the messy entanglement of wires and cables, and improving the standardization and aesthetics of the wiring.

[0057] According to some embodiments of the front door assembly 100 for a vehicle of the present application, the electronic control housing 4 further includes: an outer shell 46, which is sleeved on the outer periphery of the plurality of first support plates 41, and the outer shell 46 is accommodated in the interior of the installation cavity 311 and has a wire groove 461 which passes through in the radial direction formed on the outer shell 46.

[0058] The outer shell 46 is sleeved on the outer periphery of the plurality of first support plates 41. As a solid outer shell, the outer shell 46 can absorb and disperse part of the impact force, protect the internal electronic control components from being damaged, and evenly disperse the external force to the entire shell structure to avoid excessive local force causing damage to the electronic control board 44 or other key components; a wire groove 461 is formed on the outer shell 46 and penetrates in the radial direction, which facilitates the arrangement of wires. In the front door assembly 100 of the vehicle, the electronic control system needs to connect multiple components, such as a drive motor, a control switch, etc., so there will be a large number of wires. The existence of the wire groove 461 allows these wires to pass through the outer shell 46 in an orderly manner, avoiding the messy entanglement of wires and cables.

[0059] The outer shell 46 is sleeved on the outer circumference of multiple first support plates 41, and together with the first support plates 41 and the second support plates 42, constitutes a complete electronic control housing 4 structure, thereby enhancing the structural integrity and rigidity of the entire electronic control housing 4. The cooperation between the outer shell 46 and the first support plates 41 can effectively transmit and disperse external forces, so that the electronic control housing 4 can maintain a stable shape and structure when subjected to various external forces.

[0060] According to some embodiments of the front hatch assembly 100 for a vehicle, a wiring harness channel extending obliquely to the axis of the cylinder 31 is formed at the end of the cylinder 31 , and the angle between the axis of the wiring harness channel and the axis of the cylinder 31 is an acute angle.

[0061] The wiring harness channel formed at the end of the cylinder 31 extends obliquely to the axis of the cylinder 31, and the angle between the axis and the axis of the cylinder 31 is an acute angle, which changes the direction of the wiring harness and avoids the situation in the traditional vertical or parallel wiring harness channel. When the wiring harness moves with the opening and closing of the front hatch, due to the relationship between the movement direction and the channel direction, the wiring harness is prone to bending and entanglement at the channel mouth, which leads to wire jamming. When the wiring harness channel is inclined, the bending angle of the wiring harness when passing through the channel is more reasonable. When the front hatch is opened or closed, the driving rod 3 drives the hatch 2 to move, and the wiring harness will move with it. Due to the inclined design of the wiring harness channel, the movement trajectory of the wiring harness in the channel is a relatively smooth curve, rather than a sharp bend, which greatly reduces the possibility of the wiring harness being stuck at the channel mouth.

[0062] According to some embodiments of the present application, the front hatch assembly 100 for a vehicle further includes a linkage hinge 5, which is symmetrically arranged on both sides of the hatch cover 2 with the driving rod 3, and the linkage hinge 5 hinges the hatch and the hatch body.

[0063] The linkage hinge 5 and the driving rod 3 are symmetrically arranged on both sides of the hatch cover 2. The symmetrical layout can make the hatch cover 2 more evenly stressed at the connection part. During the opening and closing process of the hatch cover 2, the driving rod 3 is responsible for providing the main power to realize the movement of the hatch cover 2, while the linkage hinge 5 plays a supporting and stabilizing role on the other side. When the driving rod 3 pushes the hatch cover 2 to open upward, the linkage hinge 5 will rotate accordingly to maintain the balance of the two sides of the hatch cover 2 and prevent the hatch cover 2 from tilting or shaking due to uneven force. The symmetrical structure ensures that the hatch cover 2 can be stably connected to the hatch door body under various working conditions, thereby improving the overall structural stability of the front hatch door assembly 100 and reducing component damage or abnormal noise that may be caused by unstable connection.

[0064] The following is a brief description of a vehicle according to an embodiment of the present application.

[0065] The vehicle according to the embodiment of the present application includes a vehicle body 10 and a front hatch assembly 100 of any of the above embodiments, and the front hatch assembly 100 is arranged on the vehicle body 10. Since the vehicle according to the present embodiment is provided with the front hatch assembly 100 of any of the above embodiments, the vehicle according to the present application has a front hatch assembly 100 with high driving convenience. When the front cabin storage box needs to be used to place or take out items, the front hatch 2 can be opened or closed by operating a control device such as a button in the vehicle or a smart key, thereby avoiding the automatic rebound caused by the failure of the hydraulic struts that are prone to occur in the traditional mechanical opening and closing structure in low temperature environments such as winter, and the existing mechanical card The front door assembly 100 can operate stably and reliably, reducing the troubles and inconveniences that users may encounter during operation, providing users with a more comfortable and convenient use experience, and improving user satisfaction with the vehicle; at the same time, since at least part of the electronic control housing 4 is accommodated in the interior of the drive rod 3, the space inside the vehicle is effectively saved. The front door assembly 100 makes the spatial layout of the front cabin area more compact, providing more possibilities for the installation and arrangement of other vehicle components, and also providing users with a larger front cabin storage space, meeting the user's demand for vehicle storage space.

[0066] According to some embodiments of the present application, the vehicle further includes: a kick sensor 6 , which is arranged on a side of the vehicle body 10 close to the front door assembly 100 , and the kick sensor 6 is arranged at the bottom of the vehicle body 10 .

[0067] The kick sensor 6 is arranged on one side of the vehicle body 10 close to the front door assembly 100 and is located at the bottom of the vehicle body 10, providing a convenient operation method for the user. When the user holds items in both hands and cannot use traditional buttons or keys to open the front door, the user only needs to gently kick the location of the sensor with his foot to trigger the opening operation of the front door. At this time, there is no need to put down the items in his hand to find the key or operation button. The front door can be easily opened to place items through the kick sensor 6, which greatly saves time and energy, improves the user's convenience experience in actual use, and makes the operation of the vehicle more user-friendly.

[0068] In some embodiments of the present application, the kick sensor 6 is installed on the inner side of the front bumper by gluing or fixing the clip. The kick sensor 6 adopts a self-capacitance detection capacitance scheme, that is, a unipolar capacitance detection to ground. The self-capacitance uses a pin and measures the capacitance between the pin and the ground. The working principle of the self-capacitance sensing system is to drive the current on the pin connected to the sensor and measure the voltage. If the human body, conductor, etc. are placed on or close to the sensor, the measured capacitance will increase. In this way, the kicking action made by the human body can be detected, and the required function of the kick sensor 6 can be realized. The kick sensor 6 is arranged in the front bumper area, which is greater than 50-70mm along the length direction of the vehicle body 10 and greater than 100mm along the height direction of the vehicle body 10; being in this area is ergonomic and has the best capacitance sensing area.

[0069] The following briefly describes a control method for the front door assembly 100 according to an embodiment of the present application.

[0070] According to the control method for the front door assembly 100 of the embodiment of the present application, it includes: controlling the drive motor to drive the hatch 2 to close after obtaining the front hatch 2 closing command; controlling to trigger the anti-pinch function of the front door after the drive motor torque reaches a first preset value, and starting compensation for the opening angle of the front hatch 2 according to the motor speed and adjusting the first preset value.

[0071] According to the control method for the front door assembly 100 of the embodiment of the present application, when the front hatch 2 closing command is obtained, the drive motor is started. Since the drive motor is the actuator that drives the hatch 2 to open and close, the drive motor is operated to convert electrical energy into mechanical energy, thereby pulling the drive rod 3 to move the hatch 2 in the closing direction.

[0072] During the operation of the drive motor, when the torque reaches a first preset value, the control triggers the anti-pinch function of the front hatch. When the torque of the drive motor reaches a certain level, it means that the hatch 2 has encountered an obstacle during the closing process. For example, there may be foreign objects sandwiched between the hatch 2 and the front cabin body 1. At this time, if the hatch 2 continues to be forcibly closed, it may not only damage the hatch 2 and the foreign objects, but also cause damage to related parts of the vehicle and even cause harm to personnel. Therefore, by setting the torque to reach the first preset value to trigger the anti-pinch function, abnormal situations can be detected in time to ensure safe use.

[0073] At the same time, the opening angle of the front hatch 2 is started and compensated according to the motor speed and the first preset value is adjusted. The motor speed can reflect the actual movement state of the hatch 2. If the motor speed is abnormal, it may mean that the movement of the hatch 2 is affected, such as resistance changes. By monitoring the motor speed, the opening angle of the hatch 2 can be understood in real time. When it is found that the motor speed is not consistent with the expectation, the opening angle of the front hatch 2 is started and compensated, which can ensure that the hatch 2 can reach the predetermined position and avoid the inaccurate closing position of the hatch 2 due to various interference factors. In addition, the first preset value is adjusted according to the actual operation situation, so that the triggering condition of the anti-pinch function can be more in line with the actual use scenario. With the changes in the vehicle use environment, such as temperature, humidity, etc. affecting the performance of the components, or the components themselves are worn with the increase of use time, the original first preset value is no longer the most suitable standard for triggering the anti-pinch function. By dynamically adjusting the first preset value, the system can better adapt to different working conditions, improve the accuracy and reliability of the control of the entire front hatch assembly 100, and ensure that the front hatch can operate safely and accurately under various conditions.

[0074] It can be understood that when the door opening signal of opening the hatch 2 is detected, the electronic control board 44 controls the drive motor to execute the drive instruction. At this time, the drive motor runs and the hatch 2 is opened. During this period, the running stroke of the drive rod 3 is determined by the calculated Hall number, and the Hall number is stored in the corresponding storage area in the electronic control board 44.

[0075] When the door closing signal of closing the hatch cover 2 is detected, the drive motor executes the command, and the drive motor reverses at this time, and the hatch cover 2 is closed. During this period, the travel of the drive rod 3 is determined by the Hall number of the storage area. When all the Hall numbers are just run, the hatch cover 2 reaches the bottom and triggers the half-lock position signal of the front cover lock. The half-lock signal is transmitted to the electronic control board 44, and the electronic control board 44 controls the hatch cover 2 lock to be attracted. When it is attracted to be fully locked, the full lock signal is fed back to the vehicle processing module. After waiting for 100ms, the support rod controller sends a command to control the hatch cover 2 lock to perform a reset operation. After the reset is completed, the command is sent to the support rod controller. At this point, the entire front hatch cover 2 electric opening and closing process is completed.

[0076] It should be noted that the first drive motor torque is set to X, and the electronic control board 44 executes the door closing command. If the anti-pinch function is not triggered, the subsequent anti-pinch force remains unchanged; if the anti-pinch function is triggered, the drive motor torque increases or decreases based on X. If the anti-pinch function is not triggered subsequently, the drive motor torque is used this time, and so on.
