[0032] In some embodiments, optionally, as shown in Figure 1 a ride space adjustment method is proposed, comprising:

[0033] Step S101, under the condition that a user is seated on a seat, obtaining a hip point coordinate and a heel point coordinate of the user.

[0034] In this embodiment, the vehicle comprises a seat, a horizontal floor and a footrest, the footrest is arranged on the horizontal floor, and the footrest is a baffle for placing the user's feet.

[0035] Exemplarily, the horizontal floor can be a movable horizontal floor, and the footrest can be a footrest with adjustable position and angle.

[0036] Under the condition that a user is seated on a seat, obtaining a hip point coordinate and a heel point coordinate of the user, wherein the user is a passenger of the vehicle, the hip point coordinate is a coordinate of a hip point of the user, and the heel point coordinate is a coordinate of a heel point of the user.

[0037] Exemplarily, the hip point coordinate can be a three-dimensional coordinate of the hip point of the user, and the heel point coordinate can be a three-dimensional coordinate of the heel point of the user.

[0038] Exemplarily, the user can be an average-sized passenger.

[0039] Exemplarily, under the condition that the user is seated on the seat, image data of the user can be collected, and the joint point coordinates of the user can be determined according to the image data of the user, the joint point coordinates can include the hip point coordinate and the heel point coordinate.

[0040] Step S102, determining a horizontal distance between the hip point and the heel point of the user according to the hip point coordinate and the heel point coordinate.

[0041] The hip point coordinate and the heel point coordinate are processed to obtain a horizontal distance between the hip point and the heel point of the user, wherein the horizontal distance represents a horizontal position difference between the hip point and the heel point of the user.

[0042] Exemplarily, a difference between horizontal coordinates in the hip point coordinate and the heel point coordinate is calculated to obtain the horizontal distance between the hip point and the heel point.

[0043] Exemplarily, the position of the foot rest can be adjusted first, and the horizontal distance between the hip point and the heel point is determined after the position of the foot rest is fixed.

[0044] In step S103, a first included angle corresponding to the user is determined according to the horizontal distance.

[0045] The first included angle corresponding to the user is determined based on the horizontal distance, wherein the first included angle is an angle corresponding to an ankle joint of the user.

[0046] Exemplarily, the first included angle can be a comfortable angle corresponding to the ankle joint of the user.

[0047] In step S104, the angle of the foot rest is adjusted so that a difference between a second included angle and the first included angle is less than a preset angle threshold.

[0048] The angle of the foot rest is adjusted based on the first included angle so that a difference between a second included angle and the first included angle is less than a preset angle threshold, wherein the second included angle is an included angle between the foot rest and the horizontal floor, and the angle threshold is a preset angle.

[0049] Exemplarily, the angle threshold can be 1 degree.

[0050] It should be noted that the included angle between the foot rest and the horizontal floor is adjusted to the first included angle, so that when the user places the foot on the foot rest, the user's ankle can be ensured to be in a comfortable state.

[0051] The adjustment method of the seating space in the embodiment adjusts the included angle between the foot rest and the horizontal floor according to the first included angle, ensures that the user's foot is maintained in a comfortable position, improves the comfort of the user's ankle joint, and improves the accuracy of the adjustment of the seating space in the vehicle, ensures that the user has enough seating space in the vehicle, optimizes the movement space of the user's foot in the vehicle, and improves the comfort of the user.

[0052] In some embodiments, optionally, an adjustment method of a seating space is provided, which determines a first included angle according to a horizontal distance, comprising:

[0053] In step S201, a preset ankle joint angle is obtained.

[0054] The preset ankle joint angle is obtained, wherein the ankle joint angle is an angle of an ankle joint of the user, that is, an included angle between a lower leg and a foot.

[0055] Exemplarily, the ankle joint angle can be 95 degrees.

[0056] Step S202, while keeping the ankle joint angle unchanged, the knee joint angle of the user is adjusted to determine the foot plane position corresponding to the knee joint angle.

[0057] In the case of keeping the ankle joint angle unchanged, the knee joint angle of the user is adjusted to different angles, and then the foot plane position corresponding to the knee joint angle is determined, wherein the knee joint angle is the angle of the knee joint of the user, that is, the included angle between the thigh and the calf.

[0058] Exemplarily, the ankle joint angle can be the foot angle (that is, the included angle between the foot plane and the calf line), and the ankle joint angle is set to the most comfortable foot angle of the larger target human body, and the knee angle (that is, the included angle between the calf line and the thigh line) is a variable value, and each knee angle corresponding to the foot plane position is recorded in units of 1°.

[0059] Step S203, determining the functional relationship according to the knee joint angle and the foot plane position.

[0060] According to the knee joint angle and the foot plane position, the functional relationship between the horizontal distance and the first included angle is determined, wherein the functional relationship is used to represent the relationship between the horizontal distance and the first included angle.

[0061] The functional relationship can be:

[0062] y = 0.147x - 83.7;

[0063] Wherein, x is the horizontal distance, and y is the first included angle.

[0064] Step S203, determining the first included angle according to the horizontal distance and the functional relationship.

[0065] The horizontal distance is substituted into the functional relationship as an input value to obtain the first included angle.

[0066] The adjustment method of the seating space in the embodiment determines the functional relationship according to the knee joint angle and the foot plane position, and then determines the first included angle according to the horizontal distance and the functional relationship, which ensures the data accuracy of the first included angle. The accurate first included angle ensures the accuracy of the adjustment of the seating space in the vehicle, ensures that the user has enough seating space in the vehicle, and further ensures the seating comfort of the user.

[0067] In some embodiments, optionally, an adjustment method of a seating space is provided, and the adjustment method of the seating space further comprises:

[0068] Step S301, obtaining a preset angle threshold and a distance threshold.

[0070] The angle threshold is a threshold of an angle between thighs and shanks of the user, and the distance threshold is a threshold of a distance between the shanks of the user and a boundary of a seat cushion.

[0071] Exemplarily, the angle threshold can be 90 degrees, and the distance threshold can be 5 centimeters.

[0072] In step S302, the first distance is determined according to the angle threshold and the distance threshold.

[0073] The first distance is determined according to the angle threshold and the distance threshold, and the first distance is a target distance between the first baffle and the footrest.

[0074] In step S303, the position of the first baffle is adjusted so that the distance between the first baffle and the footrest is equal to the first distance.

[0075] The position of the first baffle is adjusted so that the distance between the first baffle and the footrest is equal to the first distance.

[0076] Exemplarily, the position of the first baffle is adjusted so that the distance between the first baffle and the footrest is close to the first distance.

[0077] The adjustment method of the seating space in this embodiment sets the distance between the first baffle and the footrest as the first distance, guarantees the space between the first baffle and the footrest, and further guarantees the moving space of the legs and feet of the user in the vehicle, thereby improving the seating comfort of the user.

[0079] In step S401, a preset ankle joint angle is obtained.

[0080] In this embodiment, the vehicle further comprises a second baffle.

[0081] Exemplarily, the second baffle can be above the horizontal floor.

[0082] The ankle joint angle is an angle of an ankle joint of the user.

[0083] In step S402, a knee joint moving distance of the user is determined by adjusting the knee joint angle of the user while keeping the ankle joint angle unchanged.

[0084] The knee joint moving distance of the user is determined by adjusting the knee joint angle of the user while keeping the ankle joint angle unchanged.

[0085] Exemplarily, the ankle joint angle can be a foot angle, the ankle joint angle is set to the most comfortable foot angle (i.e. the included angle between the foot plane and the calf line) of the large target human body, the knee angle (i.e. the included angle between the calf line and the thigh line) is a variable value, and each knee angle corresponding to the uppermost boundary of the leg (i.e. the knee joint moving distance) is recorded in units of 1°. The leg motion envelope of the large human body can be obtained by fitting all the boundaries.

[0086] In step S403, the first volume is determined according to the knee joint moving distance.

[0087] The first volume corresponding to the leg of the user is determined based on the knee joint moving distance, wherein the first volume is the motion space of the leg of the user.

[0088] Exemplarily, the first volume can be the volume corresponding to the movable space of the knee and the leg of the user.

[0089] In step S404, the position of the second baffle is adjusted so that the volume of the space between the second baffle and the horizontal floor is equal to the first volume.

[0090] The position of the second baffle is changed so that the volume of the space between the second baffle and the horizontal floor is equal to the first volume.

[0091] The adjustment method of the seating space in the embodiment sets the volume of the space between the second baffle and the horizontal floor as the first volume, ensures the space between the first baffle and the horizontal floor, and further ensures the motion space of the leg of the user in the vehicle, thereby improving the seating comfort of the user.

[0092] In some embodiments, optionally, an adjustment method of a seating space is provided, and the adjustment method of the seating space further includes:

[0095] The foot moving distance is the movable distance of the foot of the user.

[0096] Exemplarily, the foot moving distance can be the moved distance of the foot of the user while keeping the position of the knee of the user unchanged.

[0097] The positions of the third baffle and the fourth baffle are adjusted respectively, and the distance between the third baffle and the fourth baffle is set as the foot moving distance.

[0098] The positions of the third baffle and the fourth baffle are adjusted respectively, and the distance between the third baffle and the fourth baffle is set as the foot moving distance.

[0099] Exemplarily, the foot moving distance can be 50 centimeters.

[0100] The adjustment method of the riding space in the embodiment sets the distance between the third baffle and the fourth baffle as the foot moving distance, ensures the distance between the third baffle and the fourth baffle, ensures the moving space of the user's foot through the distance between the third baffle and the fourth baffle, and improves the comfort of the user's foot during the process of riding.

[0101] In some embodiments, optionally, an adjustment method of a riding space is provided, and the adjustment method of the riding space further includes:

[0102] In step S601, a preset height value is obtained.

[0103] In the embodiment, the horizontal floor can move up and down, and the height value is a preset height value between the horizontal floor and the cushion of the seat.

[0104] Exemplarily, the height value can be 60 centimeters.

[0105] In step S602, the height position of the horizontal floor is adjusted, so that the height difference between the horizontal floor and the cushion of the seat is equal to the height value.

At the same time, consider the gap between the seat cushion 902 boundary and the calf, and at the same time satisfy the above two conditions, thus the rear space boundary of the foot can be determined.

[0154] In some embodiments, optionally as shown in FIG. 9D, Figure 7 Figure 7 ​​​​C in the formula is the first type of human knee front boundary, Figure 7 D in the formula is the second type of human knee front boundary. Set the most comfortable foot angle (i.e. the angle between the foot plane and the calf line) of the larger target human body as A, and the knee angle (i.e. the angle between the calf line and the thigh line) as a variable value, record the uppermost boundary of the leg corresponding to each knee angle, and fit all the boundaries to obtain the leg movement envelope of the larger human body. In the same way, the leg movement envelope of the smaller human body can be obtained. The upper boundary of the leg of the target population can be obtained by taking the union of the above movement envelopes. Generally, a proper design allowance or safety gap can be added to the upper boundary of the leg of the target population.

[0155] In some embodiments, as shown in Figure 8 The seat 1002 can be an adjustable seat, the horizontal floor 1004 can be a foot horizontal floor, the foot rest 1006 can be a foot front rest, the first baffle 1008 can be a foot rear baffle, the second baffle 1010 can be a foot left baffle, and the third baffle 1012 can be a foot right baffle. The foot horizontal floor provides foot support and is adjusted up and down through a slide rail and a slide block structure to meet the needs of different sitting postures of the passenger. The foot rear baffle provides simulation of the space boundary at the rear of the foot and is installed on the foot horizontal floor and adjusted forward and backward through a slide rail and a slide block structure to meet the needs of foot retraction. The foot front rest provides simulation of the space boundary at the front of the foot and is installed on the foot horizontal floor, adjusted forward and backward through a slide rail and a slide block structure, and adjusted in angle through a rotating shaft mechanism to meet the needs of foot extension. The foot left baffle and the foot right baffle are independently installed on the framework and adjusted left and right relative to the human body through a slide rail and a slide block structure to meet the needs of left and right movement of the legs and feet.
