In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figures 1 to 3As shown, an embodiment of the first aspect of the utility model provides a rotating shaft mechanism, including a support shaft 1, a rotating member 2 and two limiting members 3. The rotating member 2 is sleeved on the support shaft 1, and the rotating member 2 is rotatably connected to the support shaft 1, that is, the rotating member 2 can rotate around the axis of the support shaft 1. The limiting member 3 is arranged on the support shaft 1, and the two limiting members 3 are respectively arranged at both ends of the rotating member 2. The two limiting members 3 can be limited at both ends of the rotating member 2, so that the rotating member 2 can only rotate between the two limiting members 3, thereby reducing the displacement or shaking of the rotating member 2. One of the limiting member 3 and the rotating member 2 is provided with a boss 21, and the other is provided with a groove 31. For example, the limiting member 3 can be provided with a groove 31, and the rotating member 2 can be partially extended with a boss 21, the boss 21 is rotatably connected to the groove 31, and the boss 21 can abut against the side wall of the groove 31.

[0042] With such arrangement, the pivot mechanism can be applied to the driver surround so that the corresponding supporting components can be installed on the driver surround, and the boss 21 can rotate at a preset angle within the range of the groove 31, so that the rotating member 2 can rotate around the support shaft 1 to a preset angle and be limited by the abutment between the boss 21 and the side wall of the groove 31. The rotating member 2 can be used to connect the supporting components to support users such as tour guides. After use, it can also be stored by rotating the rotating member 2, reducing the obstruction of areas such as passenger passages. It is easy to use and facilitates the combination of the driver surround and the pivot mechanism to have the function of supporting standing users, thereby avoiding the situation where the tour guide is prone to tipping over when standing and explaining in the car.

[0043] like Figure 1 to Figure 2 As shown, in some embodiments, the rotating shaft mechanism also includes an elastic member 4, which is arranged between the limiting member 3 and the rotating member 2. The elastic member 4 can provide elastic force for the rotation of the rotating member 2. With such arrangement, when the rotating member 2 rotates relative to the supporting shaft 1 under the action of an external force, the elastic member 4 can be squeezed to undergo elastic deformation to store energy. After the external force disappears, the elastic member 4 restores the deformation to enable the rotating member 2 to automatically rotate and rebound, which is convenient to use.

[0044] In this embodiment, the elastic member 4 can be, but is not limited to, a spring or a tube made of a memory alloy, and can exert a force on the rotating member 2 to return it to its original position.

[0045] In some embodiments, the elastic member 4 is configured as a spring, which is sleeved on the support shaft 1. One end of the spring is fixedly connected to the rotating member 2, and the other end of the spring is fixedly connected to the limit member 3. The rotating member 2 can pull the spring to twist and store energy under the action of external force. After the external force disappears, the spring recovers and deforms to drive the spring to twist and rebound in the opposite direction. The support shaft 1 can guide the axial direction of the spring to prevent the spring from deviating along its own axial direction.

[0046] like Figure 1 to Figure 2As shown, in some embodiments, the rotating member 2 and the limiting member 3 are arranged in parallel along the axial direction of the support shaft 1, and the boss 21 can extend into the groove 31 along the axial direction of the support shaft 1, so that the rotating member 2 and the limiting member 3 can be installed with the support shaft 1 as the standard, with high coaxiality, and the radial size of the rotating member 2 can be reduced. The circumference of the boss 21 is smaller than the circumference of the groove 31, so that the boss 21 can extend into the groove 31 and rotate along the circumference of the groove 31. For example, the circumference of the boss 21 can be one-quarter to three-quarters of the circumference of the groove 31, so that there is sufficient supporting strength between the boss 21 and the groove 31 and the rotation angle requirement of the rotating member 2 can be met.

[0047] In addition, the rotating member 2 can also be partially sleeved on the circumference of the limiting member 3, and the boss 21 can extend into the groove 31 along the radial direction of the support shaft 1. The rotating member 2 is rotatably connected to the support shaft 1, and the boss 21 slides in the groove 31 to limit the rotation angle of the rotating member 2.

[0048] like Figures 2 to 4 As shown, in some embodiments, the rotating shaft mechanism also includes a sleeve 5, which is sleeved on the rotating member 2 and fixedly connected to the rotating member 2. The sleeve 5 is located between the two limit members 3. With this arrangement, the sleeve 5 can move synchronously with the rotating member 2 and rotate around the support shaft 1 together. The sleeve 5 can be connected to external supporting components. The sleeve 5 can not only protect the rotating member 2, the elastic member 4, the support shaft 1 and other components, but also increase the installable area of ​​the external supporting components, thereby improving the supporting stability.

[0049] In this embodiment, the limit member 3 has a flange, which can block and limit the sleeve 5. The sleeve 5 can be set between the flanges of the two limit members 3 and close to the flange position, so as to effectively shield and protect the components between the two limit members 3.

[0050] like Figures 1 to 3 As shown, in some embodiments, a connecting ring 51 is provided on the inner wall of the sleeve 5, and a supporting ring 32 is provided on the limiting member 3. The connecting ring 51 can be sleeved on the supporting ring 32 and rotatably connected with the supporting ring 32. With such a configuration, when the sleeve 5 is sleeved on the rotating member 2, the connecting ring 51 can be sleeved on the supporting ring 32, and can provide support between the sleeve 5 and the limiting member 3 or between the sleeve 5 and the support shaft 1, thereby improving the stability of the sleeve 5 during rotation and avoiding stress concentration at the connection position between the sleeve 5 and the rotating member 2.

[0051] In this embodiment, the positions and quantities of the connecting rings 51 and the supporting rings 32 correspond to each other in groups, and there are multiple groups. The multiple groups of connecting rings 51 and the supporting rings 32 are respectively arranged at the two ends of the rotating member 2, that is, the connecting rings 51 and the supporting rings 32 can be erected and supported at the two ends of the rotating member 2, and can support the two ends of the sleeve 5 and the limit member 3 to avoid the displacement of the sleeve 5 during the rotation process, so that the force at various parts of the sleeve 5 is more uniform and the rotation is more stable.

[0052] like Figures 2 to 3 as well as Figures 5 and 6 As shown, the embodiment of the second aspect of the utility model provides a driver enclosure device, including an enclosure body 6, a baffle 7 and a rotating shaft mechanism in any of the above schemes, the support shaft 1 is used to connect with the enclosure body 6, and the rotating member 2 is used to connect with the baffle 7. With such a configuration, the baffle 7 can be connected to the enclosure body 6 through the rotating shaft mechanism. When the user needs to stand and use it, the baffle 7 can be pushed to rotate around the rotating shaft mechanism at a preset angle until the boss 21 abuts against the side wall of the groove 31 to limit the baffle 7. The baffle 7 will no longer continue to rotate, and the user can lean on the baffle 7 to avoid the user from tipping over when the vehicle brakes. After use, the baffle 7 can be rotated back to its original position around the rotating shaft mechanism, which is convenient to use. The enclosure body 6 and the baffle 7 can be designed to be different sizes or shapes according to the needs of use.

[0053] In some embodiments, the rotating shaft mechanism includes an elastic member 4, which is disposed between the limiting member 3 and the rotating member 2. The rotating member 2 has at least a first position and a second position. When the rotating member 2 is in the first position, the boss 21 can abut against one side wall of the groove 31, and the baffle 7 can rotate to the vertical direction of the surrounding body 6. The elastic member 4 can undergo elastic deformation to store energy, so that the baffle 7 can limit the user together with the surface of the surrounding body 6, thereby increasing the user's leaning stability. When the rotating member 2 is in the second position, the boss 21 can abut against the other side wall of the groove 31, and the elastic member 4 can restore the deformation and apply a force to the baffle 7 through the rotating member 2 until the baffle 7 fits the surrounding body 6, and the baffle 7 is kept in abutment with the surface of the surrounding body 6, which is convenient to use.

[0054] In this embodiment, the rotating member 2 may also have other fixed positions. For example, a removable pin is provided between the rotating member 2 and the limit member 3, or between the rotating member 2 and the support shaft 1. A plurality of sockets may be provided on the limit member 3 or the support shaft 1. After the pin passes through the rotating member 2, it can be plugged into different sockets to fix the rotating member 2 at different positions.

[0055] like Figures 5 and 6 As shown, in some embodiments, the baffle 7 is configured as an arc-shaped plate, the concave surface of the arc-shaped plate is used to support external objects, and the side of the arc-shaped plate can provide centripetal force to the user and other external objects, forming a certain lateral gathering effect, thereby improving the supporting effect.

[0056] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
