Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to an electric hatchback simulation device and an electric hatchback simulation system. Background Technology

[0002] With the development of automation technology, more and more cars are adopting electric hatchbacks to achieve automatic opening and closing of the tailgate. In the early stages of electric hatchback development, as it was still in the conceptual stage, there were neither prototypes nor molds available. At this time, the center of gravity, weight, hinge installation position, and electric strut installation position of the tailgate were determined solely based on design and CAD calculations. Although relevant parameters such as hovering, manual force, current, and voltage could be obtained through theoretical calculations, there were still differences between theory and practice. Therefore, it was necessary to conduct experiments using simulation devices to quickly verify the rationality of the design before formal mold making.

[0003] Currently, there are generally two types of simulation equipment for electric hatchbacks on the market. One type is a dedicated device customized for a single vehicle model, requiring different devices for different models. This method is expensive, time-consuming, and requires reinvestment should a design change be made, making it difficult to invest in and participate in the early stages of a project; it can only be used for durability testing in the later stages. The other type of equipment adapts to different vehicle models by manually adjusting the body mounting points, hatch mounting points, and center of gravity. However, manual adjustments often lead to inaccurate results, distorted values, and can easily mislead designers into making incorrect judgments. Summary of the Invention

[0004] Therefore, it is necessary to provide an electric hatch simulation device and an electric hatch simulation system to address the above problems. These devices can be applied to the simulation testing of electric hatches of different vehicle models, and can ensure the accuracy of test results and improve testing efficiency.

[0005] This application proposes an electric hatchback simulation device, comprising:

[0006] frame;

[0007] A movable adjustment mechanism includes a movable frame and a movable module. The movable frame is mounted on the machine frame via the movable module. The movable frame has a first mounting point for connecting to one end of an electric support rod.

[0008] A tailgate simulation mechanism includes a tailgate frame, a center of gravity adjustment component, and a position adjustment component. The tailgate frame is rotatably connected to the frame. Both the center of gravity adjustment component and the position adjustment component are mounted on the tailgate frame.

The counterweight can be adjusted in position relative to the tailgate frame under the action of the center of gravity adjustment component. The position adjustment component has a second mounting point for connecting to the other end of the electric support rod. The second mounting point can be adjusted in position relative to the tailgate frame under the action of the position adjustment component.

The device solves the problem of automatic matching of the center of gravity and gravitational torque through counterweight selection, automatic center of gravity fitting, and error compensation algorithms. After the tester manually places the counterweight, the electric hatchback simulation device automatically adjusts the mounting point position, center of gravity position, equivalent weight, and opening angle of the support rod. This allows it to be used for simulating electric hatchback tests on different vehicle models, ensuring the accuracy of the test results and effectively improving testing efficiency.

[0013] In one embodiment, two movable frames are provided, which are located on opposite sides of the back door frame. Each movable frame is provided with a first mounting point.

[0014] In one embodiment, the electric hatchback simulation device further includes a door lock simulation mechanism disposed on the frame, and the hatchback frame is provided with a lock body that cooperates with the door lock simulation mechanism.

[0015] In one embodiment, the door lock simulation mechanism includes an installation adjustment assembly mounted on the frame and a latch connected to the installation adjustment assembly. The installation adjustment assembly is used to drive the latch to adjust its position relative to the frame, and the latch is used to cooperate with the lock body.

[0016] In one embodiment, the latch is rotatably connected to the mounting adjustment assembly, and the door lock simulation mechanism further includes an angle adjustment assembly for adjusting the rotation angle of the latch.

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] This application discloses an electric hatchback simulation system comprising a computer device and an electric hatchback simulation device, wherein the electric hatchback simulation device is signal-connected to the computer device. The computer device serves as the computing and control center of the electric hatchback simulation system, and includes a processor, memory, network interface, display screen, and input devices connected via a system bus. The processor provides computing and control capabilities. The memory includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores the operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage medium. The network interface of the computer device is used for communication with external terminals via a network connection. The electric hatchback simulation device, as the executor of the electric hatchback simulation system, is capable of performing corresponding simulation tests under the control of the computer device.

[0030] Before conducting simulation tests, the aforementioned electric hatchback simulation system requires inputting relevant parameters into the computer interface. These parameters include hatchback mass, center of gravity, point of manual force application, opening angle, and installation point coordinates. The computer then outputs calculation results, indicating whether requirements are met and suggesting necessary adjustments. For example, it automatically outputs the required counterweight weight, the coordinates of the installation point to be adjusted, and the opening angle. Next, the electric support rod is installed onto the electric hatchback simulation device. The device adjusts the center of gravity, installation point coordinates, and opening angle based on the data output by the computer. Once the electric support rod is activated, the system simulates the hatchback's working state, thereby obtaining relevant experimental data.

[0031] Please see Figures 1 to 3 An embodiment of this application discloses an electric hatchback simulation device, including a frame 10, a movable adjustment mechanism, and a hatchback simulation mechanism 40. The movable adjustment mechanism includes a movable frame 20 and a movable module 30. The movable frame 20 is mounted on the frame 10 via the movable module 30. The movable frame 20 has a first mounting point 21 for connecting to one end of an electric support rod. The first mounting point 21 can be adjusted relative to the frame 10 under the action of the movable module 30. A force sensor 22 is provided at the first mounting point 21. The hatchback simulation mechanism 40 includes a hatchback frame 41, a center of gravity adjustment component 42, and a position adjustment component 44. The hatchback frame 41... 1. Rotatably connected to the frame 10, the center of gravity adjustment component 42 and the position adjustment component 44 are both installed on the back door frame 41. The center of gravity adjustment component 42 is used to install a counterweight. The counterweight can be adjusted in position relative to the back door frame 41 under the drive of the center of gravity adjustment component 42. The position adjustment component 44 is provided with a second mounting point 43 for connecting to the other end of the electric support rod. The second mounting point 43 can be adjusted in position relative to the back door frame 41 under the drive of the position adjustment component 44.

[0032] Specifically, the electric hatchback simulation device is used in conjunction with computer equipment. Before conducting the simulation test, the corresponding parameters are input into the computer equipment's operating interface. These parameters include hatchback mass, center of gravity, point of application of manual force, opening angle, and installation point coordinates. The computer equipment outputs relevant calculation results, prompts whether the requirements are met, and indicates areas that need adjustment. For example, it automatically outputs data such as the required counterweight weight, the installation point coordinates to be adjusted, and the opening angle. Then, the electric strut is installed. One end of the electric strut is connected to the first installation point 21, which simulates the strut's mounting point on the vehicle body. The other end of the electric strut is connected to the second installation point 43, which simulates the strut's hatchback mounting point. Testers configure appropriate counterweights based on data output from the computer equipment and install them on the center-of-gravity adjustment component 42. Activating the adjustment button on the simulation device allows the counterweights to be automatically adjusted to the appropriate position via the center-of-gravity adjustment component 42, thus achieving automatic adjustment of the tailgate's center of gravity. The moving module 30 enables automatic adjustment of the first mounting point 21 (i.e., the body mounting point of the strut), and the position adjustment component 44 enables adjustment of the second mounting point 43 (i.e., the tailgate mounting point of the strut). The moving adjustment mechanism rotates the tailgate frame 41 to a specified starting angle, achieving automatic adjustment of the tailgate opening angle. Once adjusted, the electric strut begins operation, driving the tailgate simulation mechanism 40 to rotate relative to the frame 10, simulating the working state of a car tailgate. Simultaneously, the force sensor 22 acquires relevant operating parameters of the electric strut, allowing for the collection of information such as tailgate suspension, manual force, current, voltage, motor speed, and velocity. This allows the verification of theoretical calculations and design rationality, which previously required 2-3 months, to be completed within 2 hours, significantly improving testing efficiency.

[0033] The aforementioned electric hatchback simulation device, when used in conjunction with a computer, allows for automatic calculation and output of relevant results (such as the required counterweight weight, the coordinates of the mounting points to be adjusted, and the opening angle) after the corresponding vehicle model parameters are input into the computer. The device solves the problem of automatic matching of the center of gravity and gravitational torque through counterweight selection, automatic center of gravity fitting, and error compensation algorithms. After the tester manually places the counterweight, the electric hatchback simulation device automatically adjusts the mounting point position, center of gravity position, equivalent weight, and opening angle of the support rod. This allows it to be used for simulating electric hatchback tests on different vehicle models, ensuring the accuracy of the test results and effectively improving testing efficiency.

[0034] Furthermore, to simulate manually opening and closing the tailgate and collect relevant test data, in this embodiment, the frame 10 is equipped with a rotating shaft 50 and a drive component 60 for driving the rotating shaft 50 to rotate. An angle sensor 70 is mounted on the rotating shaft 50, and the tailgate frame 41 is connected to the rotating shaft 50. When the electric support rod is not working, the drive component 60 is activated, causing the rotating shaft 50 to rotate, which in turn rotates the tailgate frame 41. This simulates manually opening and closing the door, and the angle sensor 70 acquires the corresponding data. The drive component 60 can specifically be a drive motor, such as a stepper motor or a servo motor.

[0035] Further, in this embodiment, the moving module 30 includes an X-axis moving module connected to the frame 10, a Z-axis moving module drivenly connected to the X-axis moving module, and a Y-axis moving module drivenly connected to the Z-axis moving module. The movable frame 20 is drivenly connected to the Y-axis moving module. Specifically, as... Figures 1 to 3 As shown, a spatial rectangular coordinate system is established, where the X-axis direction corresponds to... Figure 1 The forward and backward directions, the Y-axis direction corresponds to Figure 1 The left and right directions, the Z-axis direction corresponds to Figure 1 The frame 10 includes a base 11, two columns 12 spaced apart on the base 11, and a crossbeam 13 connected to the top of the two columns 12. The back door frame 41 of the back door simulation mechanism 40 is rotatably connected to the crossbeam 13 via a pivot 50 extending along the Y-axis. Without external force, the back door frame 41 is in a naturally drooping state. When the movable frame 20 moves back and forth under the drive of the X-axis moving module 30, the back door frame 41 can rotate around the pivot 50, so that the back door frame 41 forms a certain initial angle with the Z-axis. Through the cooperation of the X-axis moving module, the Y-axis moving module, and the Z-axis moving module, the movable frame 20 can be automatically adjusted in the X-axis, Y-axis, and Z-axis directions, thereby enabling the spatial position adjustment of the first mounting point 21 within the aforementioned rectangular coordinate system. Specifically, the X-axis moving module, Y-axis moving module, and Z-axis moving module can achieve linear reciprocating motion of the movable frame 20 in the corresponding directions by using a combination of drive motor and transmission structure. The transmission structure here includes, but is not limited to, a nut and screw transmission structure, a gear and rack transmission structure, or a synchronous belt transmission structure.

[0036] Further, please refer to Figure 4 In this embodiment, the center of gravity adjustment component 42 includes a Z-axis adjustment component 421 connected to the back door frame 41, an X-axis adjustment component 422 drivenly connected to the Z-axis adjustment component 421, and a counterweight mounting component 423 drivenly connected to the X-axis adjustment component 422.

[0037] Specifically, such as Figure 4 and Figure 5 As shown, the tailgate frame 41 is generally rectangular, and the center of gravity adjustment component 42 is installed within the inner frame of the tailgate frame 41. It should be noted that the Z-axis and X-axis here are both based on... Figure 5 The state of the rear door frame 41 when naturally drooping is used as a reference. The Z-axis adjustment assembly 421 includes a first drive member and a Z-axis nut screw pair connected to the first drive member. The X-axis adjustment assembly 422 includes a second drive member and an X-axis nut screw pair connected to the second drive member. The counterweight mounting piece 423 is connected to the X-axis nut screw pair. After selecting a suitable counterweight, it is installed on the counterweight mounting piece 423. Through the cooperation of the Z-axis adjustment assembly 421 and the X-axis adjustment assembly 422, the position of the counterweight can be adjusted, thereby achieving automatic adjustment of the rear door's center of gravity. In this embodiment, both the Z-axis adjustment assembly 421 and the X-axis adjustment assembly 422 use a nut screw pair structure for transmission adjustment, which is simple in structure and provides higher adjustment accuracy.

[0038] Furthermore, such as Figure 2 As shown, in this embodiment, two movable frames 20 are provided, located on opposite sides of the back door frame 41. Each movable frame 20 is provided with a first mounting point 21. Position adjustment components 44 are provided on opposite sides of the back door frame 41, and each position adjustment component 44 is provided with a second mounting point 43. Specifically, as... Figure 4 As shown, the position adjustment assembly 44 includes an adjustment handwheel, a lead screw, and a slider. The lead screw extends along the Z-axis and is rotatably mounted on the outside of the back door frame 41. The slider is threadedly connected to the lead screw. The adjustment handwheel is connected to one end of the lead screw, and the second mounting point 43 is located on the slider. By manually rotating the adjustment handwheel, the lead screw rotates, which in turn moves the slider along the lead screw, thereby enabling manual adjustment of the second mounting point 43. Of course, in other embodiments, the adjustment handwheel can be replaced by a drive motor to achieve automatic adjustment of the second mounting point 43. The two position adjustment assemblies 44 can adjust the positions of the mounting points of the electric support rods on both sides respectively, thereby further ensuring the accuracy of the test.

[0039] In addition, in order to more realistically simulate the interaction between the car body and the tailgate, such as Figure 3 As shown, further, based on the above embodiment, the electric hatch simulation device also includes a door lock simulation mechanism 80 disposed on the frame 10, and the hatch frame 41 is provided with a lock body 45 that cooperates with the door lock simulation mechanism 80. Through the cooperation of the door lock simulation mechanism 80 and the lock body 45, the unlocking and locking states between the hatch and the vehicle body can be simulated.

[0040] Please combine Figure 6 Furthermore, in this embodiment, the door lock simulation mechanism 80 includes an installation adjustment assembly 81 mounted on the frame 10, and a latch 82 connected to the installation adjustment assembly 81. The installation adjustment assembly 81 is used to drive the latch 82 to adjust its position relative to the frame 10, and the latch 82 is used to cooperate with the lock body 45. During testing, the position of the latch 82 is adjusted by the installation adjustment assembly 81, so that the latch 82 can better adapt to the position of the lock body 45, which can further improve its applicability. Specifically, in this embodiment, the installation adjustment assembly 81 includes an X-axis moving unit 811 disposed on the base 11, a Y-axis moving unit 812 drivenly connected to the X-axis moving unit 811, and a lifting unit 813 drivenly connected to the Y-axis moving unit 812. The latch 82 is drivenly connected to the lifting unit 813. By cooperating with the X-axis moving unit 811, the Y-axis moving unit 812, and the lifting unit 813, the latch 82 can be adjusted in multiple directions along the X-axis (front-back direction), Y-axis (left-right direction), and Z-axis (up-down direction). Optionally, in this embodiment, both the X-axis moving unit 811 and the Y-axis moving unit 812 employ an adjusting handwheel and a lead screw mechanism. Rotating the adjusting handwheel drives the lead screw to move, achieving linear reciprocating motion in the corresponding direction. The lifting unit 813 employs an adjusting handwheel in conjunction with a scissor lift platform. Rotating the adjusting handwheel achieves the lifting motion of the scissor lift platform. Thus, the latch 82 can be manually adjusted to a suitable position. Of course, in other embodiments, the X-axis moving unit 811, the Y-axis moving unit 812, and the lifting unit 813 can also be electrically driven, thereby enabling automatic adjustment of the latch 82's position.

[0041] Furthermore, in this embodiment, the latch 82 is rotatably connected to the mounting adjustment assembly 81, and the door lock simulation mechanism 80 further includes an angle adjustment assembly 83, which is used to adjust the rotation angle of the latch 82. Specifically, the angle adjustment assembly 83 includes a rotating shaft and an adjustment handle connected to the rotating shaft. The latch 82 is connected to the rotating shaft. By adjusting the handle, the rotating shaft is rotated to adjust the latch 82 to a suitable angle, and then the adjustment handle is locked, thereby keeping the latch 82 at the adjusted angle. Thus, through the cooperation of the mounting adjustment assembly 81 and the angle adjustment assembly 83, the latch 82 can be adjusted in multiple directions (front and back, left and right, up and down), and the angle of the latch 82 can also be adjusted, making the door lock simulation mechanism 80 more suitable for the tailgates of different vehicle models.

[0042] Furthermore, in this embodiment, the electric hatchback simulation device also includes a buffer mechanism 90 disposed on the frame 10. The buffer mechanism 90 is used to buffer the engagement of the lock body 45 and the door lock simulation mechanism 80. Specifically, a stop is provided on the side of the hatchback frame 41. When the hatchback simulation mechanism 40 moves to the vicinity of the door lock simulation mechanism 80, the stop on the hatchback frame 41 can contact the buffer mechanism 90. Under the action of the buffer mechanism 90, buffering and vibration reduction can be achieved, thereby reducing the impact force between the hatchback simulation mechanism 40 and the door lock simulation mechanism 80. The buffer mechanism 90 includes, but is not limited to, a spring buffer mechanism or a hydraulic buffer mechanism. Optionally, in this embodiment, two sets of buffer mechanisms 90 are provided. The two sets of buffer mechanisms 90 are respectively located on opposite sides of the hatchback frame 41, and the opposite sides of the hatchback frame 41 are respectively provided with stopes corresponding to the buffer mechanisms 90.
