[0026] DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of the present application, the present application will be described in more detail below in combination with the drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element or one or more intervening elements can be present therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element or one or more intervening elements can be present therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in the present specification are only for the purpose of illustration.

[0028] ​​Unless otherwise defined, all technical and scientific terms used in the present disclosure have the same meanings as those commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. All publications, patent applications, patents, and other references mentioned in this specification are herein incorporated by reference in their entirety for the purpose of describing and disclosing, for example, the methodologies described in such publications, which might provide useful background to the present application.

[0029] Currently, intelligent mobile robots are used for indoor movement of people with difficulty in moving, and some devices can move outdoors. However, in any of the above environments, when the intelligent mobile robot is reversing, the backrest thereof often needs to contact other external objects or human bodies. In contact with other external objects or human bodies, it is easy to cause damage to the human body riding on the intelligent mobile robot or to the human body that is contacted, and there is a safety hazard.

[0030] Based on this, please refer to Figure 1 and Figure 2 The present application provides a cockpit device 1000, which comprises a seat mechanism 100 and a backrest mechanism 200. The backrest mechanism 200 comprises a driving assembly 210, a first backrest assembly 220, a second backrest assembly 230, and a first sensor 240. The driving assembly 210 comprises a driving shaft 211, which is installed on the seat mechanism 100 and at least partially extends out. The first backrest assembly 220 is connected to the driving shaft 211 and is located at the part of the driving shaft 211 that extends out. The second backrest assembly 230 is installed on the seat mechanism 100 and is arranged in a spaced manner with the first backrest assembly 220. The second backrest assembly 230 is located on the side of the first backrest assembly 220 away from the seat mechanism 100. The first sensor 240 is installed on the second backrest assembly 230 and is used to sense the distance between the second backrest assembly 230 and an object outside the cockpit device 1000. The first backrest assembly 220 is movable between a first preset position and a second preset position. In the first preset position, the first backrest assembly 220 is higher than the seat mechanism 100. In the second preset position, the first backrest assembly 220 is lower than the seat mechanism 100.

[0031] It should be noted that the cockpit device 1000 is switched between the first preset position and the second preset position by the first backrest assembly 220, so as to open or close the cockpit. The first backrest assembly 220 is located at the rear of the cockpit device 1000, which is convenient for a user to enter the cockpit device 1000 from the rear. The driving shaft 211 is at least partially extended out of the seat mechanism 100, so as to leave space for the first backrest assembly 220 and the second backrest assembly 230, so as to facilitate the movement of the first backrest assembly 220. Alternatively, the first backrest assembly 220 can be moved between the first preset position and the second preset position by rotating or lifting. The second backrest assembly 230 is fixed at the rear of the seat mechanism 100, so that the second backrest assembly 230 can contact an object or a human body close to the cockpit device 1000 from the rear when the cockpit device 1000 moves to any position, thereby further improving the safety performance of the cockpit device 1000.

[0032] Through the above structure, no matter whether the first backrest assembly 220 is in the first preset position or the second preset position, the second backrest assembly 230 can trigger the first sensor 240 after contacting other external objects or human bodies, thereby reducing the safety hazard.

[0033] In some embodiments, referring to Figures 3 to 5In combination with other figures, the first sensor 240 includes an anti-collision sensor 241, which includes: an elastic shell 2411, a first conductor 2412, and a second conductor 2413, the elastic shell 2411 is hollowly provided with an elastic cavity 2411a and first and second wall surfaces 2411b and 2411c opposite to the elastic cavity 2411a, the first conductor 2412 is arranged on the first wall surface 2411b, and the second conductor 2413 is arranged on the second wall surface 2411c. When the elastic shell 2411 is forced to be extruded and the distance between the first conductor 2412 and the second conductor 2413 is less than a threshold value, the anti-collision sensor 241 is triggered. Optionally, the first sensor 240 further includes at least one of a pressure-sensitive sensor, an infrared sensor, and a visual sensor. The elastic shell 2411 is arranged in a "convex" shape or a "cross" shape, the elastic cavities 2411a at both sides and the middle part of the elastic shell 2411 are contracted when the elastic shell 2411 is forced, the distance between the first conductor 2412 and the second conductor 2413, the above-mentioned threshold value can be 0, that is, the first conductor 2412 and the second conductor 2413 are in contact to trigger the first sensor 240, or the above-mentioned threshold value can be a distance greater than 0, so that the first conductor 2412 and the second conductor 2413 are close without contact to trigger the first sensor 240; the elastic shell 2411 is expanded when it is not forced, the distance between the first conductor 2412 and the second conductor 2413 is greater than the above-mentioned threshold value, thereby disconnecting the first sensor 240. It can be understood that the first conductor 2412 and the second conductor 2413 are metal conductors, and whether the distance between the first conductor 2412 and the second conductor 2413 meets the above-mentioned threshold value is obtained by detecting whether the current is turned on. It still needs to be explained that the above-mentioned first sensor 240 is different from the conventional infrared sensor, which can reduce the volume of the first sensor 240 and realize the miniaturization of the structure. Thus, the first sensor 240 is conveniently arranged in the above-mentioned cabin device 1000 space smaller area, improves the detectable area of the cabin device 1000, improves the information acquisition ability of the user state, and improves the intelligence of the cabin device 1000.

[0034] In some embodiments, referring to Figure 6 In combination with other figures, the second backrest assembly 230 includes an anti-collision support 231 and an anti-collision back cushion 232, at least part of the anti-collision support 231 extends from the seat mechanism 100 along a first direction F1, another part of the anti-collision support 231 is arranged along a second direction F2, and the anti-collision back cushion 232 is mounted on the anti-collision support 231. The movement direction of the first backrest assembly 220 is perpendicular to the first direction F1, and the plane where the anti-collision support 231 is located is parallel to the movement direction of the first backrest assembly 220. It can be understood that the anti-collision back cushion 232 is arranged away from the seat mechanism 100, which is used to contact objects or human bodies outside the cabin device 1000, can slow down the impact and prevent the impact force from being too large, thereby improving the safety. Optionally, the anti-collision back cushion 232 can be a material with elasticity.

[0035] Further, referring to Figure 6 , and in combination with other drawings, the anti-collision support 231 comprises a support body 2311 and a mounting member 2312, the mounting member 2312 is mounted on the seat mechanism 100 along a first direction F1, and the support body 2311 is spaced apart from the first backrest assembly 220 along a second direction F2. Wherein, the first backrest assembly 220 is rotatably mounted on the drive shaft 211, and the first backrest assembly 220 rotates towards the direction away from the mounting member 2312 in the process of rotation, the mounting member 2312 is used for mounting the support body 2311 and limiting the rotation of the first backrest assembly 220. That is, the above-mentioned support body 2311 and mounting member 2312 can be an integral part that is integrally formed and mounted on the seat mechanism 100, or can be a split type combined part. It is arranged on one side of the seat mechanism 100, so that when the first backrest assembly 220 rotates relative to the seat mechanism 100, it will be blocked by the mounting member 2312 and cannot rotate a whole circle, thereby limiting the activity of the first backrest assembly 220 and reducing the possibility of damage to the first backrest assembly 220. In some other embodiments, the first backrest assembly 220 can also be a linear lifting mechanism, and the above-mentioned mounting member 2312 can also play a limiting role.

It can be understood that the above-mentioned "higher" and "lower" refer to the observation parallel to the surface for sitting in the seat mechanism 100, higher than the seat mechanism 100 means that the first backrest assembly 220 can be observed, lower than the seat mechanism 100 means that the first backrest assembly 220 cannot be observed; when the first backrest assembly 220 rotates to the first preset position, the first backrest assembly 220 and the seat mechanism 100 together form a cabin, when the first backrest assembly 220 rotates to the second preset position, the first backrest assembly 220 opens the cabin to facilitate the user to enter or exit the cabin device 1000 from the rear of the cabin device 1000. The second backrest assembly 230 is lower than the seat mechanism 100 in the first preset position or the second preset position, on the one hand, so that the second backrest assembly 230 does not hinder the user from entering or leaving the cabin whether the cabin is open or closed; on the other hand, the second backrest assembly 230 can more contact the bed corner, table corner, toilet edge and other external objects with lower height in indoor use environment.

[0037] In some embodiments, referring to Figure 3 In combination with other figures, the first backrest assembly 220 further comprises a second sensor 224, which is installed between the backrest support 222 and the back cushion 223, and is used to detect whether a human body is leaning on the back cushion 223. The backrest rod 221 is further provided with a wire groove 2211 for accommodating the cable of the second sensor 224. It can be understood that the second sensor 224 can also be the anti-collision sensor 241 described above. For the specific structure of the anti-collision sensor 241, please refer to the above description, that is, by detecting the distance between the backrest support 222 and the back cushion 223 to confirm whether the human body contacts the back cushion 223.

The seat cushion 130 is further provided with a displacement inclined surface 131, the thickness of the displacement inclined surface 131 near the outer edge of the seat cushion 130 is smaller than the thickness of the displacement inclined surface 131 near the inner part of the seat cushion 130. It can be understood that the seat body 110 serves as the installation basis of the cabin device 1000, and the seat cover plate 120 can be used to support the seat cushion 130, and the edge thereof is provided with a similar inclined surface in combination with the displacement inclined surface 131, thereby improving the comfort of human body sitting.

[0039] In combination with the above-mentioned seat mechanism 100, the driving assembly 210 is further described, please refer to Figure 6In combination with other figures, the driving assembly 210 further comprises a motor 212 and a motor cover plate 213, the motor 212 is installed on the seat body 110, the motor cover plate 213 covers the motor 212, the seat cover plate 120 is provided with a motor opening 121, at least part of the motor cover plate 213 is exposed to the motor opening 121, and at least part of the motor cover plate 213 is protruding relative to the motor opening 121. The driving shaft 211 is rotationally connected to the motor 212, and the driving shaft 211 can rotate clockwise or counterclockwise under the driving of the motor 212. It can be understood that the motor 212 can be a servo motor 212 or a motor, etc., and the motor opening 121 is provided at the seat cover plate 120 in order to protrude part of the motor cover plate 213 relative to the motor opening 121, thereby reducing the thickness, the motor cover plate 213 provides structural strength to protect the motor 212, and at the same time, the above-mentioned cushion 130 and the motor 212 can also be separated, thereby preventing the vibration generated during the operation of the motor 212 from affecting the user's experience through the cushion 130.
