For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In one aspect of the embodiment of the present application, referring to Figure 1 and Figure 2 , provides an independently driven leg and foot device 10, including: a base 11, a left leg and foot massage part 12, a right leg and foot massage part 13, a first left driving component and a first right driving component; the driving end of the first left driving component is drivingly connected to the left leg and foot massage part 12 to drive the left leg and foot massage part 12 to perform telescopic movement relative to the base 11; the driving end of the first right driving component is drivingly connected to the right leg and foot massage part 13 to drive the right leg and foot massage part 13 to perform telescopic movement relative to the base 11.

[0034] It can be understood that the left leg and foot massage part 12 is used to massage the user's left leg and left foot, and the right leg and foot massage part 13 is used to massage the user's right leg and right foot. Preferably, the left leg and foot massage part 12 and the right leg and foot massage part 13 are respectively provided with cavities, which are used to massage and fix the user's limbs.

[0035] The first left drive assembly is fixed on the base 11, and the first left drive assembly has a first drive end, and the first drive end reciprocates along the length direction of the left leg and foot massage part 12 (the length direction of the user's left leg), and the left leg and foot massage part 12 is connected to the first drive end, so as to follow the movement of the first drive end. Similarly, the second right drive assembly is fixed on the base 11, and the second right drive assembly has a second drive end, and the second drive end reciprocates along the length direction of the right leg and foot massage part 13 (the length direction of the user's right leg), and the right leg and foot massage part 13 is connected to the second drive end, so as to follow the movement of the second drive end. The left leg and foot massage part 12 and the right leg and foot massage part 13 are driven to reciprocate in a straight line direction relative to the base 11 respectively, and are independently retracted, so that different stretch lengths and massage parts can be provided for the left leg and foot of the user and the right leg and foot, and meet the user's customized needs for the left leg and foot and the right leg and foot massage respectively.

[0036] In this embodiment, the structures of the left leg and foot massage part 12 and the right leg and foot massage part 13 are not limited, as long as they can massage the user's legs and feet. The structures of the first left driving component and the first right driving component are also not limited, as long as they can respectively drive the left leg and foot massage part 12 and the right leg and foot massage part 13 to reciprocate in a straight line relative to the base 11.

[0037] For example, the left leg and foot massage part 12 includes a left leg massage part 121 and a left foot massage part 122, the right leg and foot massage part 13 includes a right leg massage part 131 and a right foot massage part 132, the left foot massage part 122 is drivingly connected to the driving end of the first left driving component, and the right foot massage part 132 is drivingly connected to the driving end of the first right driving component.

[0038] It can be understood that the left leg massage part 121, the right leg massage part 131, the left foot massage part 122 and the right foot massage part 132 are used to massage the user's left leg, right leg, left foot and right foot respectively. Preferably, the left leg massage part 121, the right leg massage part 131, the left foot massage part 122 and the right foot massage part 132 are respectively provided with cavities, which are used to massage and fix the user's limbs.

[0039] Furthermore, the left leg massage part 121 and the right leg massage part 131 are integrally connected and fixedly connected to the base 11, and do not expand and contract with the expansion and contraction of the left foot massage part 122 and the right foot massage part 132. Alternatively, the left leg massage part 121 is fixedly connected to the left foot massage part 122, and expands and contracts with the expansion and contraction of the left foot massage part 122, and the right leg massage part 131 is fixedly connected to the right foot massage part 132, and expands and contracts with the expansion and contraction of the right foot massage part 132.

[0040] Optionally, in an achievable manner of an embodiment of the present application, the first left drive component includes a left telescopic motor 141, a left screw rod 142 drivingly connected to the left telescopic motor 141, and a left screw rod nut 143 cooperating with the left screw rod 142, and the left leg and foot massage part 12 is arranged on the left screw rod nut 143; the first right drive component includes a right telescopic motor 151, a right screw rod 152 drivingly connected to the right telescopic motor 151, and a right screw rod nut 153 cooperating with the right screw rod 152, and the right leg and foot massage part 13 is arranged on the right screw rod nut 153.

[0041] The left screw rod 142 is fixedly connected to the output shaft of the left telescopic motor 141, and the output shaft of the left telescopic motor 141 rotates to drive the left screw rod 142 to rotate. The left screw rod nut 143 is sleeved on the left screw rod 142 and is threadedly connected with the left screw rod 142. The left screw rod 142 rotates forward or reversely, and the left screw rod nut 143 can be driven to move linearly in two opposite directions. The left leg and foot massage part 12 is fixed on the left screw rod nut 143, so the left leg and foot massage part 12 can reciprocate along the axial direction of the left screw rod 142. It can be understood that the axis of the left screw rod 142 should be parallel to the length direction of the left leg and foot massage part 12 (the length direction of the user's left leg). The motion principle of the right leg and foot massage part 13 is the same as the motion principle of the left leg and foot massage part 12, and the present embodiment will not be repeated here.

[0042] Optionally, in one achievable manner of an embodiment of the present application, the independently driven leg and foot device 10 further includes a control component, which is electrically connected to the first left drive component and the first right drive component, respectively, to control the movement of the left leg and foot massage part 12 and / or the right leg and foot massage part 13.

[0043] The control component can independently control the movement of the first left driving component and the first right driving component, thereby driving the left leg and foot massage part 12 and the right leg and foot massage part 13 to do the following: Figure 3 The synchronous or asynchronous stretching movements shown can achieve the effect of customized stretching of the user's legs.

[0044] Optionally, in one implementable manner of an embodiment of the present application, the control component includes a control unit, a left leg and foot length detection unit, and a right leg and foot length detection unit, the control unit is electrically connected to the left leg and foot length detection unit, the right leg and foot length detection unit, the first left drive component, and the second right drive component, respectively, the left leg and foot length detection unit is disposed on the left leg and foot massage part 12, and is used to detect the user's left leg length information, and the right leg and foot length detection unit is disposed on the left leg and foot massage part 12, and is used to detect the user's right leg length information.

[0045] The left leg and foot length detection unit can be used to obtain the appropriate length parameters for the extension and contraction of the user's left leg and foot, as well as the position parameters of the left leg and foot massage part 12 in the extension and contraction path during the massage process. The left leg and foot length detection unit sends the above parameters to the control unit. After the control unit obtains the above parameters, it determines the degree to which the left leg and foot massage part 12 needs to be moved along the direction of the user's left leg, and drives the first left drive component to act through the program. The control process of the first right drive component is the same as the control process of the first left drive component, which will not be repeated here. The control unit is allowed to control at least one of the left leg and foot massage part 12 and the right leg and foot massage part 13 to move up and down along the direction of the user's legs, and combine to drive the user's left and right feet to perform synchronous or asynchronous extension and contraction, thereby achieving the effect of customized stretching of the user's legs.

[0046] For example, the left leg and foot length detection unit includes a left code bar 1611 and a left length sensor 1612. The left code bar 1611 is set on the base 11 and extends along the length direction of the left leg and foot massage part 12. The left length sensor 1612 is fixed on the left leg and foot massage part 12 and moves with the left leg and foot massage part 12. The left length sensor 1612 moves up and down on the left code bar 1611. The position of the left leg and foot massage part 12 moving up and down can be known through the algorithm of the left encoder. The control unit controls the left leg and foot massage part 12 to move to a fixed position at a fixed time by analyzing and processing the position parameters obtained. The right leg and foot length detection unit includes a right code bar 1621 and a right length sensor 1622. The right code bar 1621 is set on the base 11 and extends along the length direction of the right leg and foot massage part 13. The right length sensor 1622 is fixed on the right leg and foot massage part 13 and moves with the right leg and foot massage part 13. The right length sensor 1622 moves up and down on the right code bar 1621. The position of the right leg and foot massage part 13 moving up and down can be known through the algorithm of the right encoder. The control unit controls the right leg and foot massage part 13 to move to a fixed position at a fixed time by analyzing and processing the position parameters obtained.

[0047] Optionally, in one possible implementation of the embodiment of the present application, please refer to Figure 2 One of the base 11 and the left leg and foot massage part 12 is provided with a left slide rail 171, and the other is provided with a left slide groove 172 that cooperates with the left slide rail 171; one of the base 11 and the right leg and foot massage part 13 is provided with a right slide rail, and the other is provided with a right slide groove 173 that cooperates with the right slide rail.

[0048] The left slide rail 171 is slidably connected to the left slide groove 172, maintaining the stability of the left leg and foot massage part 12 moving up and down relative to the base 11. The right slide rail is slidably connected to the right slide groove 173, maintaining the stability of the right leg and foot massage part 13 moving up and down relative to the base 11.

[0049] Optionally, in one possible implementation of the embodiment of the present application, please refer to Figure 1 The left leg and foot massage part 12 includes a left leg massage part 121 and a left foot massage part 122, and the right leg and foot massage part 13 includes a right leg massage part 131 and a right foot massage part 132; please refer to Figure 4 and Figure 5 The independently driven leg and foot device 10 also includes a second left driving component and a second right driving component arranged on the base 11. The driving end of the second left driving component is drivingly connected to the left foot massage part 122 to drive the left foot massage part 122 to perform an "up and down nodding" type of oscillation motion or a clockwise or counterclockwise rotation motion relative to the base 11; the driving end of the second right driving component is drivingly connected to the right foot massage part 132 to drive the right foot massage part 132 to perform an "up and down nodding" type of oscillation motion or a clockwise or counterclockwise rotation motion relative to the base 11.

[0050] The second left driving assembly and the second right driving assembly respectively drive the left foot massage part 122 and the right foot massage part 132 to swing or rotate synchronously or asynchronously, so as to achieve the effect of customizing the user's ankle. At the same time, the telescopic movement of the left leg and foot massage part 12 and the right leg and foot massage part 13 can provide the user with more forms of massage experience.

[0051] Optionally, in an achievable manner of an embodiment of the present application, the control component includes a control unit, a left foot angle detection unit and a right foot angle detection unit, the control unit is electrically connected to the left foot angle detection unit, the right foot angle detection unit, the second left drive component and the second right drive component, respectively, the left foot angle detection unit is arranged on the left foot massage part 122, and is used to detect the angle between the axis of the left foot massage part 122 and the axis of the left leg massage part 121, and the right foot angle detection unit is arranged on the right foot massage part 132, and is used to detect the angle between the axis of the right foot massage part 132 and the axis of the right leg massage part 131.

[0052] The angle parameters between the axis of the left foot massage part 122 and the axis of the left leg massage part 121 can be obtained through the left foot angle detection unit. The left foot angle detection unit sends the above angle parameters to the control unit. After the control unit obtains the above parameters, it drives the second left drive component to perform a "nodding up and down" type of yaw motion, or a clockwise or counterclockwise rotation motion through a program. The control process of the second right drive component is the same as the control process of the second left drive component, which is not repeated here. The control unit is allowed to control at least one of the left foot massage part 122 and the right foot massage part 132 to perform a yaw motion or a rotation motion, and a combination of driving the user's left and right ankles to perform synchronous or asynchronous yaw or rotation motions, thereby achieving the effect of customizing the user's ankles. The second left drive component and the second right drive component are independently electrically connected to the control unit respectively, and the purpose of independently moving a unilateral ankle can also be achieved.

[0053] For example, please refer to Figure 6 The second left driving assembly includes a left yaw motor 181 and a left eccentric driving assembly 182 drivingly connected to the left yaw motor 181. The left foot massage part 122 is connected to the left eccentric driving assembly 182. The left yaw motor 181 drives the left eccentric driving assembly 182 to rotate, so that the left foot massage part 122 can perform the following operations: Figure 4 and Figure 5 The second right driving assembly includes a right yaw motor 191 and a right eccentric driving assembly 192 connected to the right yaw motor 191. The right foot massage part 132 is connected to the right eccentric driving assembly 192. The right yaw motor 191 drives the right eccentric driving assembly 192 to rotate, so that the right foot massage part 132 can perform the following operations: Figure 4 and Figure 5 The structures of the left eccentric drive assembly 182 and the right eccentric drive assembly 192 are prior art and will not be described in detail in this embodiment.

[0054] Furthermore, the left foot angle detection unit includes a left encoder 1631 and a left yaw sensor 1632. The left encoder 1631 rotates synchronously with the left eccentric drive assembly 182. The left yaw sensor 1632 remains stationary relative to the left foot massage part 122. The angle parameters of the yaw of the left foot massage part 122 can be obtained through the algorithm of the left encoder. The control unit controls the left foot massage part 122 to yaw to a fixed position at a fixed time by analyzing and processing the obtained angle parameters. The right foot angle detection unit includes a right encoder 1641 and a right yaw sensor 1642. The right encoder 1641 rotates synchronously with the right eccentric drive assembly 192. The right yaw sensor 1642 remains stationary relative to the right foot massage part 132. The angle parameters of the yaw of the right foot massage part 132 can be obtained through the algorithm of the right encoder. The control unit controls the right foot massage part 132 to yaw to a fixed position at a fixed time by analyzing and processing the obtained angle parameters.

[0055] Optionally, in one achievable manner of the embodiment of the present application, at least one massage component is respectively provided in the left leg and foot massage part 12 and the right leg and foot massage part 13, and the massage component is used to massage the legs and feet of the user.
