[0087] The following describes exemplary embodiments of the present disclosure with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well - known functions and structures are omitted below.
[0088] In the field of autonomous driving, autonomous driving operation vehicles can provide operation and diversified services to the public, which helps to accelerate the unmanned travel for all. However, various problems may occur during the operation process, so the autonomous driving operation test is very necessary.
[0089] However, in the autonomous driving operation test of related technologies, the road test is highly dependent on people and consumes a lot of manpower.
[0090] To solve at least one of the above problems, an embodiment of the present disclosure provides a simulation device, including at least one of the following: a switch door button operation sub-device for installation in the vehicle, a vehicle-mounted screen click sub-device for installation in the vehicle, a seat pressure simulation sub-device for installation in the vehicle, a seat belt plugging and unplugging simulation sub-device; wherein, the switch door button operation sub-device is used to simulate an in-vehicle occupant pressing the switch door button, the vehicle-mounted screen click sub-device is used to simulate an in-vehicle occupant clicking on the vehicle-mounted screen, the seat pressure simulation sub-device is used to simulate an in-vehicle occupant sitting on the seat, and the seat belt plugging and unplugging simulation sub-device is used to simulate an in-vehicle occupant plugging and unplugging the seat belt. Thus, in the test scenario, the participation of vehicle-end personnel can be reduced or even avoided, manpower can be saved, and the test efficiency can be improved, thereby reducing the test cost.
[0091] The simulation device provided by the embodiment of the present disclosure can be applied to the autonomous driving operation test scenario, and can be specifically installed on the vehicle in the autonomous driving operation test scenario to simulate the operations of vehicle-end personnel, that is, in-vehicle occupants. The simulation device includes at least one of the following: a switch door button operation sub-device, a vehicle-mounted screen click sub-device, a seat pressure simulation sub-device, a seat belt plugging and unplugging simulation sub-device. In a specific implementation, the simulation device can include any one of the above sub-devices, or include a combination of any multiple of the above sub-devices. Which specific sub-devices the simulation device includes can be set according to the test requirements.
[0092] Next, the structures, functions and implementation processes of the above sub-devices will be illustrated by examples. It can be understood that: the vehicle in the following embodiments can refer to an autonomous driving vehicle (also known as a driverless car), or can also be other transportation tools with passenger or cargo carrying functions.
[0093] In some embodiments, a vehicle is usually provided with a switch door button for controlling the opening or closing of the door. The switch door button can be used to receive a control instruction from an in-vehicle occupant for opening or closing the door, so that the vehicle can control the door driving device to open or close the door according to the control instruction. Generally speaking, for the convenience of users, the switch door button is usually set near the B-pillar of the vehicle.
[0094] Please refer to Figures 1 to 4The door switch button operation sub-device 100 includes: a first driving member 110, a transmission member 120, a follower 130 and a first elastic member 170. The first driving member 110 is used to be fixed to a first mounting position in the vehicle. The first driving member 110 can be directly installed at the first mounting position, or indirectly installed at the first mounting position through a bracket or the like. The specific position of the first mounting position can be set according to the position of the door switch button 901. The first mounting position can be located near the B-pillar of the vehicle; for example, the first driving member 110 is fixed to the armrest 902 near the B-pillar of the vehicle.
[0095] The first driving member 110 is connected to the transmission member 120. The transmission member 120 is hinged to the fixed end of the follower 130. The end of the follower 130 away from the transmission member 120 is used as a free end, and the free end is folded relative to the fixed end in a direction toward the vehicle's door opening and closing button 901. Under the action of the driving force provided by the first driving member 110, the transmission member 120 can drive the free end of the follower 130 to apply a pressing force along the pressing direction to the vehicle's door opening and closing button 901, thereby simulating the pressing operation of the vehicle occupant on the door opening and closing button 901.
[0096] The fixed end of the follower 130 may refer to the portion of the follower 130 close to the transmission member 120. The free end of the follower 130 may refer to the portion of the follower 130 away from the transmission member 120, that is, the portion of the follower 130 close to the door switch button 901.
[0097] The first elastic member 170 is used to provide a first buffering force when the free end of the operating rod 132 moves toward the door switch button 901, so as to prevent the operating rod 132 from causing excessive impact on the door switch button 901 when the operating rod 132 moves toward the door switch button 901. The first elastic member 170 may be a tension spring. In other examples, the first elastic member 170 may also be a member made of other elastic materials such as rubber.
[0098] In this embodiment, when the vehicle occupant needs to press the door switch button 901, the first driving member 110 can drive the transmission member 120 to rotate, and the transmission member 120 drives the follower 130 hinged thereto to move, so that the free end of the follower 130 moves toward the direction of the door switch button 901 until the free end of the follower 130 overcomes the first buffering force of the first elastic member 170 and applies a pressing force along the pressing direction to the door switch button 901, thereby completing the pressing operation of the door switch button 901. In this way, in the test scenario, there is no need for the vehicle-side personnel to press the door switch button 901, which is conducive to reducing or even avoiding the participation of the vehicle-side personnel, saving manpower, and improving the test efficiency, thereby reducing the test cost.
[0099] After the door opening / closing button 901 is pressed in place, the first driving member 110 can drive the transmission member 120 to rotate in the reverse direction, thereby driving the free end of the follower member 130 to move away from the door opening / closing button 901 until there is a preset distance between the free end of the follower member 130 and the door opening / closing button 901.
[0100] In some examples, to reduce the installation difficulty of the first driving member 110, the door opening / closing button operating sub-device 100 may further include a first fixing bracket 140. The first fixing bracket 140 is fixedly connected to the first driving member 110, and the first fixing bracket 140 can be detachably connected to the component at the first installation position directly or indirectly. Among them, the specific structure and shape of the first fixing bracket 140 can be set according to actual needs.
[0101] Please refer to Figure 1 and Figure 2 , in some examples, in order to avoid modifying the internal structure of the vehicle and ensure the integrity of the vehicle interior, the door opening / closing button operating sub-device 100 may further include: a locking bolt and two hinged locking claws 150. The two locking claws 150 are hinged by a hinge shaft 160. The two locking claws 150 are used to clamp the armrest 902 of the vehicle. The two locking claws 150 are respectively provided with bolt holes 151, and the locking bolt (not shown in the figure) is used to cooperate with the two bolt holes 151 to detachably connect the two locking claws 150, so as to facilitate the connection or disconnection of the door opening / closing button operating sub-device 100 and the armrest 902.
[0102] Generally speaking, the armrest 902 may include two ends and an intermediate portion connecting the two ends. The two ends are bent relative to the intermediate portion. The locking claw 150 can be used to clamp the intermediate portion of the armrest 902. The locking bolt and the hinge shaft 160 can be respectively located on opposite sides of the intermediate portion of the armrest 902.
[0103] Optionally, in order to improve the connection reliability between the locking claw 150 and the armrest 902, the opposite inner sides of the two locking claws 150 are respectively provided with first grooves adapted to the armrest 902. In this way, when the two locking claws 150 are in a state of clamping the armrest 902, the shape of the space surrounded by the two first grooves is adapted to the shape of the armrest 902, which can not only avoid damaging the armrest 902, but also prevent the locking claw 150 from slipping off the armrest 902.
[0104] In this embodiment, when installing the door opening / closing button operation sub-device 100, rotate the two locking claws 150 in opposite directions so that the first grooves of the two locking claws 150 exactly cooperate with the armrest 902; then fasten and connect the two locking claws 150 through a locking bolt, thereby fixedly connecting the installed door opening / closing button operation sub-device 100 to the armrest 902. When disassembling the door opening / closing button operation sub-device 100, remove the locking bolt, and then the two locking claws 150 can be removed from the armrest 902, so that the installed door opening / closing button operation sub-device 100 can be removed.
[0105] In some examples, the first fixing bracket 140 can be connected to one of the locking claws 150, and the first fixing bracket 140 is also connected to the first driving member 110. Exemplarily, the first fixing bracket 140 can include: a first fixing plate and a second fixing plate, and the first fixing plate is connected to the second fixing plate. The first fixing plate can be fixedly connected to the locking claw 150 through a fastener. The second fixing plate can be disposed perpendicular to the first fixing plate, and the second fixing plate can be located below the armrest 902 (the direction indicated by the arrow in the following is the downward direction) to facilitate the installation of the first driving member 110. Figure 1 in order to facilitate the installation of the first driving member 110.
[0106] Optionally, the first fixing bracket 140 further includes at least one reinforcing rib plate, and the reinforcing rib plate is respectively connected to the first fixing plate and the second fixing plate, thereby improving the strength of the first fixing bracket 140, and further improving the installation reliability of the first driving member 110.
[0107] In some examples, the first driving member 110 can include a servo motor. The servo motor can be communicatively connected to the vehicle control system, or the servo motor can also be communicatively connected to a remote terminal to be able to receive control instructions. In other examples, the first driving member 110 can also be a motor.
[0108] Please refer to Figures 1 to 3 , in some examples, the transmission member 120 connected to the first driving member 110 can include a rotating bracket 121 and a driving rod 122. The rotating bracket 121 is connected to the first driving member 110. The rotating bracket 121 is fixedly connected to the driving rod 122, and one of the rotating bracket 121 and the driving rod 122 is hinged to the follower 130.
[0109] The rotating bracket 121 can include two relatively arranged rotating plates, the two rotating plates are respectively located on opposite sides of the servo motor, and the two rotating plates are respectively fixedly connected to the output end of the servo motor, so that the rotating plates can rotate synchronously with the output end of the servo motor. Among them, the rotating plate can be connected to the output end of the servo motor through a spline. In other examples, the rotating plate can also be connected to the output end of the servo motor through a flange or the like, or the rotating plate is fixedly connected to the output end of the servo motor through connection methods such as welding or interference fit.
[0110] The rotating bracket 121 may further include a rotating fixing plate. The rotating fixing plate may be located at the lower end of the servo motor, and there is a preset distance between the rotating fixing plate and the servo motor to prevent the servo motor from interfering with the rotation of the rotating bracket 121.

Alternatively, the rotating bracket 121 and the driving rod 122 are integrally provided by an integral molding process.
[0112] Optionally, one end of the driving rod 122 away from the rotating bracket 121 is bent in the direction towards the door opening / closing button 901, and the middle part of the driving rod 122 protrudes in the direction towards the door opening / closing button 901, so as to facilitate the arrangement of components such as the first elastic member 170 and the limiting block 180, and improve the structural compactness of the door opening / closing button operating sub-device 100.
[0113] In this embodiment, by providing the rotating bracket 121 and the driving rod 122, not only can the motion output by the first driving member 110 be transmitted to the follower 130, but also the structural compactness of the door opening / closing button operating sub-device 100 can be improved.
[0114] In some examples, one of the rotating bracket 121 and the driving rod 122 is hinged to the fixed end of the upper part of the follower 130 to drive the follower 130 to move, so that the free end of the follower 130 can apply a pressing force to the door opening / closing button 901 of the vehicle. Wherein, the free end of the follower 130 is folded relative to the fixed end in the direction towards the door opening / closing button 901 of the vehicle, which is convenient for the free end of the follower 130 to apply a pressing force to the door opening / closing button 901.
[0115] Please refer to Figures 1 to 4 , in some examples, the follower 130 may include a follower rod 131 and an operating rod 132. One end of the follower rod 131 facing the transmission member 120 forms a fixed end, and the other end of the follower rod 131 is fixedly connected to one end of the operating rod 132. The end of the operating rod 132 away from the follower rod 131 forms a free end. Wherein, there is a preset angle between the operating rod 132 and the follower rod 131, and the angle between the operating rod 132 and the follower rod 131 can be set according to actual needs; for example, the operating rod 132 is perpendicular to the follower rod 131, or the included angle between the operating rod 132 and the follower rod 131 is 80° or 100°, etc.
[0116] Among them, there may be two follower rods 131, and the two follower rods 131 are respectively located on both sides of the driving rod 122. The fixed ends of the two follower rods 131 can be hinged to the upper end of the driving rod 122 or the lower end of the rotating bracket 121, and the middle part and the lower end of the driving rod 122 are both located on the side of the follower rods 131 facing the door opening / closing button 901.
[0117] The two follower rods 131 can be fixedly connected to the operating rod 132. The lower parts of the two follower rods 131 facing away from the rotating bracket 121 are fixedly connected by a fixed shaft, and the fixed shaft is also fixedly connected to the operating rod 132. In other examples, the follower rods 131 can also be fixedly connected to the operating rod 132 by connection methods such as welding, fastening connection, or interference fit. Or, the follower rods 131 and the operating rod 132 are integrally provided by a co-forming process.
[0118] In this embodiment, by providing the follower rods 131 and the operating rod 132, it is possible to not only simulate the pressing of the door opening / closing button by the vehicle occupants, but also improve the structural compactness of the door opening / closing button operating sub-device 100.
[0119] Please refer to Figures 3 to 4 , in some examples, one end of the first elastic member 170 is fixedly connected to the follower rod 131. The end of the first elastic member 170 facing away from the follower rod 131 is fixedly connected to the end of the driving rod 122 facing away from the rotating bracket 121, thereby improving the structural compactness. In other examples, the first elastic member 170 can also be connected to the rotating bracket 121 or other components as long as its function can be achieved.
[0120] Optionally, in order to improve the structural compactness, the follower rod 131 is provided with a spring fixing member 171, and the first elastic member 170 is fixedly connected to the spring fixing member 171. There is a first distance between the spring fixing member 171 and the end face of the follower rod 131 facing the transmission member 120, and there is a second distance between the spring fixing member 171 and the end face of the follower rod 131 facing away from the transmission member 120, and the first distance is greater than the second distance.
[0121] Please refer to Figure 4 , in some examples, the door opening / closing button operating sub-device 100 further includes: a limit block 180, and the limit block 180 is fixedly connected to one of the follower rod 131 and the driving rod 122. The limit block 180 is used to abut against the other of the follower rod 131 and the driving rod 122 when the free end of the operating rod 132 reaches the limit position towards the vehicle's door opening / closing button 901, so as to prevent the pressing force applied by the operating rod 132 to the door opening / closing button 901 from being too large and causing damage to the door opening / closing button 901.
[0122] Optionally, for the convenience of installing the limiting block 180 and improving the installation reliability of the limiting block 180, the limiting block 180 may be fixedly connected to two follower rods 131 in the follower member 130, and the limiting block 180 is located on the side of the spring fixing member 171 facing the transmission member 120, so that when the free end of the operating rod 132 moves to the limit position of the vehicle's door opening / closing button 901, the limiting block 180 can abut against the middle part of the driving rod 122 protruding in the direction of the door opening / closing button 901. Among them, the limiting block 180 may be connected to the two follower rods 131 respectively, or the limiting block 180 is connected to one of the follower rods 131. The limiting block 180 may be fixedly connected to the follower rod 131 by means of welding or indirect fastening, etc., or the limiting block 180 and the follower rod 131 are integrally provided by an integral molding process. In other examples, the limiting block 180 may also be connected to the driving rod 122.
[0123] In this embodiment, when it is necessary to operate and press the door opening / closing button 901, the first driving member 110 drives the rotating bracket 121 to rotate according to the control instruction. The rotating bracket 121 drives the driving rod 122 to rotate synchronously. The driving rod 122 drives the follower rod 131 to move. One end of the follower rod 131 away from the driving rod 122 can drive the operating rod 132 to move, so that the free end of the operating rod 132 swings in the direction of the door opening / closing button 901, so that the operating rod 132 can press the door opening / closing button 901. During the process of the end of the follower rod 131 away from the driving rod 122 swinging in the direction of the door opening / closing button 901, the first elastic member 170 is in a compressed state, so that the first elastic member 170 can apply a first buffering force to the follower rod 131 to slow down the movement of the follower rod 131.
[0124] In other embodiments, the first driving member 110 may also be a linear driving member such as a linear motor or a cylinder that can output linear motion. The moving direction of the output end of the linear driving member may be parallel to the pressing direction of the door opening / closing button 901. The transmission member 120 and the follower member 130 are used to transmit the motion of the linear driving member to the door opening / closing button 901, and the specific structures of the transmission member 120 and the follower member 130 may be set according to actual needs. For example, the transmission member 120 and the follower member 130 may be rod-shaped structures respectively. The transmission member 120 is connected between the linear driving member and the follower member 130, and the linear driving member drives the follower member 130 to move toward or away from the door opening / closing button 901 through the transmission member 120.
[0125] Please refer to Figure 5, in some vehicles, an in-vehicle screen 904 is provided between two of the rear seats, facilitating interaction between vehicle occupants and the in-vehicle screen 904. Generally, a screen mounting base 904 is provided inside the vehicle. A support pad 905 is provided at the upper end of the screen mounting base 904. The support pad 905 can be used to support the hands or arms or other items of vehicle occupants; an in-vehicle screen 904 is mounted on one side of the screen mounting base 904. The in-vehicle screen 904 has a device main body 903a and a screen main body 903b. The screen main body 903b is mounted at the upper end of the device main body 903a.
[0126] Please refer to Figure 5 and Figure 6 , in order to be able to imitate the click operation of vehicle occupants on the screen, this embodiment provides an in-vehicle screen click sub-device 300, including: a second driving member 310, a first moving bracket 320, a third driving member 330, a second moving bracket 340, a jogging driving member 350 and a jogging head 360.
[0127] The second driving member 310 is used to be fixed to a second mounting position inside the vehicle. The second mounting position can be located near the in-vehicle screen 904 so that the jogging head 360 can move within the corresponding range of the in-vehicle screen 904. The second driving member 310 can be directly or indirectly mounted on the second mounting position through a bracket.
[0128] The second driving member 310 is connected to the first moving bracket 320. The second driving member 310 is used to drive the first moving bracket 320 to move along a first direction; the third driving member 330 is connected to the second moving bracket 340; the third driving member 330 is used to drive the second moving bracket 340 to move along a second direction, and the second direction is perpendicular to the first direction; the jogging driving member 350 is connected to the second moving bracket 340, the jogging driving member 350 is connected to the jogging head 360, and the jogging driving member 350 is used to drive the jogging head 360 to move towards or away from the in-vehicle screen 904. The movement direction of the jogging head 360 is perpendicular to the first direction and the second direction respectively. Among them, when the jogging head 360 moves towards the in-vehicle screen 904, it can provide a click force to the in-vehicle screen 904.
[0129] Among them, the second driving member 310 can include a driving motor that outputs rotational motion. The driving motor is connected to the first moving bracket 320 through a lead screw-nut mechanism or a gear-rack mechanism to drive the first moving bracket 320 to reciprocate along the first direction, thereby adjusting the position of the jogging head 360 in the first direction, and further adjusting the click position of the jogging head 360 on the in-vehicle screen 904. The first direction can be the longitudinal direction of the vehicle. In other examples, the second driving member 310 can be a linear motor or a cylinder or other linear driving members that can output linear motion, and the linear driving member can drive the first moving bracket 320 to reciprocate along the first direction.
[0130] The structure of the first movable bracket 320 can be set according to actual needs. For example, the first movable bracket 320 can be a block-shaped or box-shaped structure.
[0131] The third driving member 330 may include a driving motor that outputs a rotational motion, and the driving motor is connected to the second movable bracket 340 through a screw nut mechanism or a gear rack mechanism to drive the second movable bracket 340 to reciprocate along the second direction, thereby adjusting the position of the inching head 360 in the second direction, and then adjusting the click position of the inching head 360 on the vehicle screen 904. The second direction may be the lateral direction of the vehicle. In other examples, the third driving member 330 may be a linear driving member such as a linear motor or a cylinder that can output a linear motion, and the linear driving member can drive the second movable bracket 340 to reciprocate along the second direction.
[0132] The structure of the second movable bracket 340 can be set according to actual needs. For example, the second movable bracket 340 can be a block-shaped or box-shaped structure.
[0133] The inching drive 350 may be a drive member capable of outputting linear motion, such as a linear motor or a cylinder. In other examples, the inching drive 350 may include a drive motor that outputs rotary motion, and converts the rotary motion into linear motion through a screw nut mechanism or a gear rack mechanism. The inching drive 350 drives the inching head 360 to move vertically along the vehicle, so that the inching head 360 clicks the vehicle screen 904, and the distance between the inching head 360 and the vehicle screen 904 can be adjusted.
[0134] Optionally, the inching head 360 driven by the inching driving member 350 may include a hemispherical structure, a conical structure, or a cylindrical structure made of a silicone material. The inching head 360 may have a certain elasticity, so that when the inching head 360 contacts the vehicle-mounted screen 904, the elasticity of the inching head 360 itself can buffer the impact on the vehicle-mounted screen 904.
[0135] In this embodiment, when the inching head 360 needs to move from the current position to the target position, the first movable bracket 320 is driven to move along the first direction by the second driving member 310, so as to drive the inching head 360 to move along the first direction; the second movable bracket 340 is driven to move along the second direction by the third driving member 330, so as to drive the inching head 360 to move along the second direction; the inching driving member 350 is controlled to drive the inching head 360 to move downward until the inching head 360 clicks the vehicle screen 904, so as to realize the simulation of the clicking operation by the personnel in the vehicle, and realize the clicking operation at any position of the vehicle 904. In this way, in the test scenario, there is no need for the vehicle-side personnel to click the vehicle-side screen 904, which is conducive to reducing or even avoiding the participation of the vehicle-side personnel, saving manpower, and improving the test efficiency, thereby reducing the test cost.
[0136] After the clicking operation is completed, the inching head 360 is driven upward by the inching driving member 350 until there is a preset distance between the inching head 360 and the vehicle-mounted screen 904 .
[0137] In some examples, in order to reduce the difficulty of installing the second drive member 310 and ensure the integrity and compactness of the vehicle-mounted screen clicking sub-device 300, the vehicle-mounted screen clicking sub-device 300 may also include: a second fixed bracket 370, located on the periphery of the vehicle-mounted screen 904, so as not to interfere with the movement of the inching head 360. Among them, the specific structure of the second fixed bracket 370 can be set according to actual needs. Exemplarily, the second fixed bracket 370 can be a roughly rectangular frame. For example, the second fixed bracket 370 includes three fixed plates connected in sequence. For another example, the second fixed bracket 370 includes four fixed plates connected in sequence.
[0138] The second fixed bracket 370 can be detachably connected to the second driving member 310 through a plurality of fasteners. The second driving member 310 includes: a first driving motor 311, and a first screw 312 is provided at the output end of the first driving motor 311, and the axial direction of the first screw is parallel to the first direction. The first movable bracket 320 is provided with a first threaded hole that matches the first screw 312. The first threaded hole can be directly opened on the first movable bracket 320; or, the first movable bracket 320 is provided with an opening, and a first nut that matches the first screw 312 is embedded in the opening.
[0139] In this way, the rotational motion output by the first drive motor 311 can drive the first lead screw 312 to move. The first lead screw 312 can drive the first movable bracket 320 to perform more precise linear motion by cooperating with the first threaded hole, and the first movable bracket 320 can have a relatively large displacement, so that the inching head 360 has a larger range of motion in the first direction.
[0140] Optionally, in order to ensure that the first movable bracket 320 can drive the inching head 360 to move along the first direction, the vehicle-mounted screen clicking sub-device 300 further includes: a first guide rail 313, the first guide rail 313 is fixed to the second fixing bracket, the first guide rail 313 is extended along the first direction, and the first guide rail 313 is slidably matched with the first movable bracket 320. Among them, a first guide groove slidably matched with the first guide rail 313 may be provided on one side of the first movable bracket 320 facing the first guide rail 313.
[0141] The first moving bracket 320 is fixedly connected to the third driving member 330. Among them, the first moving bracket 320 can be fixedly connected to the third driving member 330 by means of welding, fastening connection, snap connection, etc. The third driving member 330 includes: a second driving motor 331, and a second lead screw 332 is provided at the output end of the second driving motor 331. The second moving bracket 340 is provided with a second threaded hole that cooperates with the second lead screw 332. The second threaded hole can be directly opened on the second moving bracket 340, or an opening is provided on the second moving bracket 340, and a second nut that cooperates with the second lead screw 332 is embedded in the opening.
[0142] In this way, the rotational motion output by the second driving motor 331 can drive the second lead screw 332 to move. The second lead screw 332 can drive the second moving bracket 340 to perform a relatively accurate linear motion through cooperation with the second threaded hole, and the second moving bracket 340 can have a relatively large displacement amount, so that the jogging head 360 has a large movement range in the second direction.
[0143] Optionally, in order to ensure that the second moving bracket 340 can drive the jogging head 360 to move in the second direction, the vehicle-mounted screen clicking sub-device 300 further includes: a second guide rail 333, the second guide rail 333 is fixed to the first moving bracket 320, the second guide rail 333 extends along the second direction, and the second guide rail 333 also cooperates with the second moving bracket 340. Among them, a second guide groove that slidably cooperates with the second guide rail 333 can be provided on one side of the second moving bracket 340 facing the second guide rail 333.
[0144] The second moving bracket 340 is fixedly connected to the jogging driving member 350. Among them, the second moving bracket 340 can be fixedly connected to the jogging driving member 350 by means of welding, fastening connection, snap connection, etc. The jogging driving member 350 includes: a first linear motor. The first linear motor includes a motor housing 351 and a central shaft 352 passing through the motor housing 351. One end of the central shaft 352 facing the vehicle-mounted screen 904 is connected to the jogging head 360.
[0145] Optionally, the central shaft 352 can be connected to the jogging head 360 through a bearing, so that the central shaft 352 drives the jogging head 360 to move vertically, and the jogging head 360 does not rotate with the central shaft 352, reducing the friction between the jogging head 360 and the vehicle-mounted screen 904. In other examples, the central shaft 352 can be fixedly connected to the jogging head 360 through a connecting member such as a flange, a coupling, or a key, so that the central shaft 352 can drive the jogging head 360 to move synchronously.
[0146] In some examples, the in-vehicle screen clicking sub-device 300 further includes: a second elastic member 353, configured to urge the jogging head 360 to move towards the in-vehicle screen 904, so as to ensure reliable contact between the jogging head 360 and the in-vehicle screen 904. For example, when the vehicle is in a bumpy state, the second elastic member 353 can also enable the jogging head 360 to be in reliable contact with the in-vehicle screen 904, thereby making the simulation effect more stable.
[0147] Optionally, to improve the structural compactness, the other end of the central shaft 352 extends out of the motor housing 351, and the second elastic member 353 can be abutted between the end of the central shaft 352 facing away from the in-vehicle screen 904 and the motor housing 351. Wherein, an installation boss 711b can be arranged on the upper part of the central shaft 352, and the second elastic member 353 can be a spring, and the spring is abutted between the installation boss 711b and the motor housing 351. In other examples, the second elastic member 353 can also be abutted between the jogging head 360 and the motor housing 351. The second elastic member 353 can also be a member made of other elastic materials.
[0148] In some examples, to improve the installation reliability of the in-vehicle screen clicking sub-device 300, the in-vehicle screen clicking sub-device 300 further includes: an eighth driving member and a first locking member 380. The eighth driving member is connected to the second fixing bracket 370. The first locking member 380 is connected to the output end of the eighth driving member. The eighth driving member is configured to drive the first locking member 380 to move to abut against the side surface of the in-vehicle screen 904, so as to lock the second fixing bracket 370 and the in-vehicle screen 904. The eighth driving member is further configured to drive the first locking member 380 to move in a direction away from the in-vehicle screen 904, so as to release the locking of the second fixing bracket 370 and the in-vehicle screen 904.
[0149] Wherein, there can be multiple first locking knobs, for example, two or three. Taking the case where there are three first locking knobs as an example: the eighth driving member can include a motor and a transmission gear set, and the first locking member 380 can be a first locking knob. The specific number of the transmission gear set can be set according to actual needs. For example, gears are respectively arranged on the output shaft of the motor and the central shafts 352 of multiple first locking knobs, and two adjacent gears are meshed. The motor can drive multiple first locking knobs to move through the transmission gear set until the multiple first locking knobs respectively abut against the side surface of the in-vehicle screen 904 to lock the second fixing bracket 370 and the in-vehicle screen 904; the motor can also drive the first locking knob to move in the reverse direction through the transmission gear, so that the first locking knob moves away from the in-vehicle screen 904, thereby releasing the locking of the second fixing bracket 370 and the in-vehicle screen 904.
[0150] Or, the number of the eighth driving members can be equal to the number of the first locking knobs, which is convenient for the eighth driving member to be directly connected to the first locking knob.
[0151] In other examples, the first locking knob may also have one, and correspondingly, the eighth driving member may also have one.
[0152] In this embodiment, when the jogging head 360 needs to move from the current position to the target position, the second driving member 310 drives the first moving bracket 320 to move in the first direction, so as to drive the jogging head 360 to move in the first direction to correspond to the target position; the third driving member 330 drives the second moving bracket 340 to move in the second direction, so as to drive the jogging head 360 to move in the second direction to correspond to the target position; the jogging driving member 350 drives the jogging head 360 to overcome the acting force of the second elastic member 353 and move downward until the jogging head 360 clicks on the vehicle-mounted screen 904, realizing the simulation of the click operation by the vehicle occupants.
[0153] Please refer to Figure 7 and Figure 8 , in some embodiments, a seat pressure simulation sub-device 500 is further provided, which can simulate the operation of a passenger sitting on the seat. In this way, in the test scenario, it is not necessary for the vehicle-end personnel to sit on the seat, which helps to reduce or even avoid the participation of the vehicle-end personnel, saves manpower, and can improve the test efficiency, thereby reducing the test cost.

The third elastic member 570 is used to provide a second buffering force when the fifth driving member 540 drives the connecting bracket 520 to move, so as to slow down the impact between the indenter 530 and the seat. In addition, when the vehicle is in a bumpy state, the third elastic member 570 can also play a buffering role. For example, it slows down the relative movement between the fifth driving member 540 and the fixed seat 550, so that the simulation effect is more stable.

Then, by controlling the fifth driving member 540, the connecting bracket 520 is driven to move vertically in the vehicle and towards the seat, so that the pressing head 530 moves downward until it can apply pressure to the seat, simulating the pressure of an occupant sitting on the seat. Among them, the magnitude of the pressure applied to the seat can be adjusted by controlling the movement amount of the pressing head 530. After the simulation is completed, the connecting bracket 520 is driven by the fifth driving member 540 to move vertically in the vehicle and away from the seat, so that the pressing head 530 moves upward. When it is no longer necessary to simulate an occupant sitting on the seat, the connector 510 is detached from the seat through the release button 513 of the connector 510, thereby removing the seat pressure simulation sub-device 500.
