[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0047] Please see Figure 1 This utility model provides a mobile device capable of moving based on user-inputted commands. For example, a user can control the mobile device to output commands to it, or the mobile device can recognize user voice or gestures to obtain user-inputted commands. Alternatively, a user can control wearable devices or mobile phones to remotely output commands to the mobile device.

[0048] Specifically, mobile devices include, but are not limited to, mobility scooters, folding strollers, and bicycles.

[0049] like Figure 1 , Figures 3 to 5 As shown, the mobile device includes a frame mechanism 10, a transmission mechanism 20, and a locking mechanism 30. The frame mechanism 10 includes a plurality of supports 100 and a steering assembly 103, the plurality of supports 100 being rotatably connected to each other, and the steering assembly 103 being rotatably connected to at least one support 100. The frame mechanism 10 has a folded state and an unfolded state.

[0050] Understandably, the multiple supports 100 are rotatably connected, and the steering assembly 103 is rotatably connected to at least one support 100, allowing the frame mechanism 10 to switch between an unfolded state and a folded state. The unfolded state is the state in which the frame mechanism 10 is fully unfolded, such as... Figure 1 and Figure 3 As shown; the folded state is the state where the frame mechanism 10 is fully folded, as shown. Figure 5 As shown. Specifically, when the frame mechanism 10 is in the folded state, the multiple supports 100 are folded in pairs relative to each other, and the supports 100 connected to the steering assembly 103 and the steering assembly 103 are folded in pairs relative to each other, resulting in a smaller overall volume of the frame mechanism 10; when the frame mechanism 10 is in the unfolded state, the multiple supports 100 are unfolded in pairs relative to each other, and the supports 100 connected to the steering assembly 103 and the steering assembly 103 are unfolded in pairs relative to each other.

[0051] like Figure 1 , Figure 3 and Figure 6As shown, the transmission mechanism 20 is further connected to at least one bracket 100 and the steering assembly 103. When the multiple brackets 100 rotate relative to each other, the transmission mechanism 20 actuates, causing the bracket 100 connected to the steering assembly 103 and the steering assembly 103 to rotate relative to each other. The locking mechanism 30 includes an operating member 301, which is rotatably connected to one of the multiple brackets. When the frame mechanism 10 is in the unfolded state, the operating member 301 can rotate relative to the bracket 100 to engage with at least another of the multiple brackets 100, so that the locking mechanism 30 restricts the relative rotation between the multiple brackets 100. The operating member 301 can also rotate relative to the bracket 100 to disengage from at least another of the multiple brackets 100, so that the locking mechanism 30 releases the restriction on the relative rotation of the multiple brackets 100. When the operating member 301 is disengaged from at least another of the multiple brackets, the operating member 301 can also drive the multiple brackets 100 to rotate relative to each other under the action of an external force, so that the frame mechanism 10 switches to a folded state.

[0052] Understandably, when the frame mechanism 10 is in the deployed state, the operating member 301 can engage with at least one of the multiple supports 100, so that the locking mechanism 30 can restrict the relative rotation between the multiple supports 100, and the multiple supports 100 remain deployed. The transmission mechanism 20 can restrict the relative rotation between the support 100 connected to the steering assembly 103 and the steering assembly 103, so that the support 100 connected to the steering assembly 103 and the steering assembly 103 remain deployed, thereby keeping the frame mechanism 10 deployed and locked as a whole, allowing the user to drive the mobile device.

[0053] Furthermore, the operating member 301 can rotate relative to the locking member 302 to separate from at least one of the multiple supports 100, thereby releasing the restriction on the relative rotation of the multiple supports 100. The operating member 301 can also drive the multiple supports 100 to rotate relative to each other under the action of external force, so that the multiple supports 100 fold relative to each other under the action of gravity. The transmission mechanism 20 can cause the supports 100 connected to the steering assembly 103 and the steering assembly 103 to rotate relative to each other, thereby causing the supports 100 connected to the steering assembly 103 and the steering assembly 103 to fold relative to each other, realizing the overall linkage folding of the frame mechanism 10 and converting it into a folded state.

[0054] The mobile device of this utility model embodiment allows the user to release the restriction on the relative rotation of multiple supports 100 by operating the control component 301. Furthermore, the control component 301 can fold multiple supports 100 and, in conjunction with the transmission mechanism, achieve the overall linkage folding of the frame mechanism 10. This makes it more convenient for the user to manually fold the mobile device, and the operation is simple. No additional drive components are required, which helps to reduce the weight of the entire vehicle.

[0055] Specifically, the frame mechanism 10 may include two or more supports 100. The multiple supports 100 may be arranged sequentially in the same direction, or the multiple supports 100 may be arranged in an array, or different sides of one support 100 may be rotatably connected to other supports 100.

[0056] For example, such as Figure 1 As shown, taking the frame mechanism 10 as an example, which includes two supports 100, the two supports 100 are a first support 101 and a second support 102, respectively. The first support 101 and the second support 102 can be arranged sequentially along the X direction. The first support 101 and the second support 102 are rotatably connected, and the steering assembly 103 is rotatably connected to the first support 101. Figure 4 and Figure 5 As shown, the first bracket and the second bracket 102 can rotate relative to each other to fold, and the steering assembly 103 and the first bracket 101 can rotate relative to each other to fold, thereby switching the frame mechanism 10 to a folded state.

[0057] For example, the rotation axis of the first bracket 101 and the second bracket 102 relative to each other is the first axis, and the rotation axis of the steering assembly 103 and the first bracket 101 relative to each other is the second axis. The first axis and the second axis can be parallel to each other; for example, both the first axis and the second axis are parallel to... Figure 1 The Y-axis, or the first axis and the second axis, may be inclined relative to each other.

[0058] In one example, when the frame mechanism 10 includes two or more supports 100, such as when the frame mechanism 10 includes a first support 101, a second support 102 and a third support, the first support 101 and the second support 102 are rotatably connected, the third support is rotatably connected to the first support 101 or the second support 102, and the operating member 301 is rotatably connected to the first support 101. The operating member 301 can rotate relative to the first support 101 to engage or disengage with the second support 102, and the third support can be driven to be connected to the first support 101 and the second support 102 through the transmission mechanism 20. When the operating member 301 rotates relative to the first support 101 to engage with the second support 102, the operating member 301 can restrict the relative rotation between the first support 101 and the second support 102, and the transmission mechanism 20 is activated to restrict the relative rotation between the third support and the first support 101.

[0059] like Figure 6 As shown, in some embodiments, the multiple supports 100 include a first support 101 and a second support 102. An operating member 301 is rotatably connected to the first support 101. The second support 102 includes a support body 1020 and a locking member 302 disposed on the support body 1020. The operating member 301 can rotate relative to the first support 101 to engage with the locking member 302, thereby restricting relative rotation between the multiple supports 100.

[0060] There may be one or more second brackets 102. For example, when there are two second brackets 102, the operating member 301 can rotate relative to the first bracket 101 to engage with the locking member 302 of different second brackets 102 respectively, thereby restricting the relative rotation between different second brackets 102 and the first bracket 101.

[0061] For example, such as Figure 4 As shown, the support bodies 1020 of the first support 101 and the second support 102 are rotatably connected. The operating member 301 is rotatably connected to the side of the first support 101 near the second support 102. The locking member 302 is provided on the side of the support body 1020 near the first support 101 so that the operating member 301 can rotate relative to the first support 101 to engage with the locking member 302.

[0062] In some embodiments, the axis of rotation of the first support 101 and the support body 1020 relative to each other is the first axis, such as... Figure 1 As shown, the first support 101 includes a first support rod 1011 and a second support rod 1012 spaced apart on the first axis. The support body 1020 includes a third support rod 1021 and a fourth support rod 1022 spaced apart on the first axis. The first support rod 1011 and the third support rod 1021 are located on the same side and rotatably connected. The second support rod 1012 and the fourth support rod 1022 are located on the same side and rotatably connected. The opposite ends of the operating member 301 can be rotatably connected to the first support rod 1011 and the second support rod 1012 respectively, ensuring the stability of the operation of the operating member 301.

[0063] For example, at least one of the first support rod 1011 and the second support rod 1012 is rotatably connected to the operating member 301, and at least one of the third support rod 1021 and the fourth support rod 1022 is provided with a locking member 302, so that one side of the operating member 301 along the first axis can be connected to the locking member 302. Alternatively, both the first support rod 1011 and the second support rod 1012 are rotatably connected to the operating member 301, and both the third support rod 1021 and the fourth support rod 1022 are provided with locking members 302, with the operating member 301 connected to the two locking members 302 on opposite sides along the first axis respectively. Specific adjustments can be made according to actual conditions and are not limited here.

[0064] For example, the operating member 301 can rotate relative to the first bracket 101 to abut against the locking member 302, or the operating member 301 can rotate relative to the first bracket 101 to engage with the locking member 302, or the operating member 301 can rotate relative to the first bracket 101 to press against the locking member 302, thereby making the operating member 301 engage with the locking member 302, and the locking mechanism 30 restricts the relative rotation of the first bracket 101 and the second bracket 102.

[0065] like Figure 6 As shown, in some embodiments, the operating member 301 includes an operating part 30111 and a connecting part 30112. The operating part 30111 is connected to the connecting part 30112, and the connecting part 30112 is connected to the first bracket 101. The operating part 30111 and the connecting part 30112 are not collinearly arranged. When the frame mechanism 10 is in the unfolded state, the first bracket 101 and the second bracket 102 are arranged along a first direction. The operating member 301 can engage with the locking member 302, and the plane containing the operating part 30111 and the connecting part 30112 is not perpendicular to the first direction, so that the locking mechanism 30 restricts the relative rotation of the first bracket 101 and the second bracket 102; and the operating member 301 can be separated from the locking member 302, and the plane containing the operating part 30111 and the connecting part 30112 is perpendicular to the first direction. Understandably, when the operating member 301 restricts the relative rotation of the first bracket 101 and the second bracket 102, the plane containing the operating part 30111 and the connecting part 30112 is not perpendicular to the first direction, so that the operating member 301 fits more closely to the first bracket 101 and the second bracket 102, avoiding affecting the user's driving of the mobile device. Moreover, the operating member 301 can at least rotate relative to the locking member 302 until the plane containing the operating part 30111 and the connecting part 30112 is perpendicular to the first direction, so that the user can operate the operating part 30111 to drive the first bracket 101 and the second bracket 102 to rotate relative to each other.

[0066] Optionally, when the operating member 301 can rotate relative to the first bracket 101 until the plane containing the operating part 30111 and the connecting part 30112 is perpendicular to the first direction, the operating member 301 and the locking member 302 separate; or, the operating member 301 can rotate relative to the first bracket 101 until the operating member 301 and the locking member 302 separate and then continue to rotate, so that the plane containing the operating part 30111 and the connecting part 30112 is perpendicular to the first direction.

[0067] For example, the first direction can be as follows Figure 1 As shown in the X direction. For example, the X direction can be horizontal. When the frame mechanism 10 is in the unfolded state, the first bracket 101 and the second bracket 102 are arranged in the horizontal direction. The plane where the operating part 30111 and the connecting part 30112 are located is not vertical, so that the user can pull the operating part 30111 upwards to make the operating part 301 rotate relative to the first bracket 101 to separate from the locking part 302. The operating part 301 can also rotate relative to the first bracket 101 until the plane where the operating part 30111 and the connecting part 30112 are located is vertical, so that the user can continue to pull the operating part 30111 upwards to drive the first bracket 101 and the second bracket 102 to rotate relative to each other, so that the frame mechanism 10 is converted to a folded state.

[0068] For example, such as Figure 1 and Figure 2As shown, the first bracket 101 also includes a connecting shaft 1013 connecting the first support rod 1011 and the second support rod 1012. The connecting portion 30112 includes an extension portion 30112a and a bushing portion 30112b. The bushing portion 30112b is sleeved on the outer periphery of the connecting shaft 1013. The extension portion 30112a connects the operating portion 30111 and the bushing portion 30112b. When the frame mechanism 10 is in the unfolded state, the operating member 301 is in contact with the locking member 302. The plane containing the extension portion 30112a of the operating member 301 and the operating portion 30111 is not perpendicular to the first direction. The operating member 301 can rotate relative to the first bracket 101 to separate from the locking member 302, and the operating member 301 can at least rotate relative to the first bracket 101 until the plane containing the extension portion 30112a and the operating portion 30111 is perpendicular to the first direction.

[0069] For example, the bushing portion 30112b has a locking portion 3012 protruding from its outer periphery. The operating part 30111 can drive the bushing portion 30112b and the locking portion 3012 to rotate about the connecting shaft 1013 via the extension portion 30112a, so that the locking portion 3012 can engage with the locking member 302, thereby restricting the relative rotation of the first bracket 101 and the second bracket 102. The operating member 301 can rotate relative to the first bracket 101 to disengage the locking portion 3012 from the locking member 302.

[0070] like Figure 1 and Figure 6 As shown, in some embodiments, when the frame mechanism 10 is in the unfolded state, the plane containing the operating part 30111 and the connecting part 30112 is parallel to the first direction. This ensures that the operating member 301 fits more closely to the first bracket 101 and the second bracket 102 when the frame mechanism 10 is unfolded, preventing the operating member 301 from protruding excessively and affecting the user's use of the mobile device.

[0071] For example, the first bracket 101 and the second bracket 102 are in the following position: Figure 1 Arranged in the X direction, the operating element 301 can rotate parallel to Figure 1 The Y direction rotates relative to the locking member 302. The X and Y directions can be horizontal. The plane where the operating part 30111 and the extension part 30112a are located can be a plane parallel to the X direction, such as a horizontal plane parallel to the X and Y directions.

[0072] like Figure 1As shown, in some embodiments, the locking mechanism 30 further includes an elastic element 303. The plurality of supports 100 include a first support 101 and a second support 102. The operating element 301 is rotatably connected to the first support 100. One end of the elastic element 303 is connected to the first support 101, and the other end of the elastic element 303 is connected to the operating element 301. The elastic element 303 is used to apply an elastic force to the operating element 301 so that the operating element 301 and the second support 102 remain in contact, thereby making the state of the locking mechanism 30 more stable. The locking mechanism 30 can stably restrict the relative rotation of the first support 101 and the second support 102, thereby improving the driving safety of the mobile device.

[0073] For example, the elastic element 303 includes, but is not limited to, elastic rope, compression spring, torsion spring, and spring sheet.

[0074] Of course, in other embodiments, the rotation of the operating member 301 can also be limited by the damping force between the operating member 301 and the first bracket 101, so that the limiting member and the locking member 302 remain in contact.

[0075] like Figures 6 to 8 As shown, in some embodiments, the operating member 301 includes a main body 3011 and a locking portion 3012. The locking portion 3012 protrudes from the main body 3011, and the main body 3011 is connected to the first bracket 101. The second bracket 102 is provided with a slot 3021, and the locking portion 3012 can engage with the slot 3021 so that the second bracket 102 can restrict the rotation of the locking portion 3012. In this way, the operating member 301 and the second bracket 102 can mutually restrict each other. The second bracket 102 restricts the angle of rotation of the operating member 301 under the action of elastic force, and the operating member 301 remains in contact with the second bracket 102, thereby restricting the relative rotation of the first bracket 101 and the second bracket 102, and the structure of the locking mechanism 30 is simpler.

[0076] For example, such as Figure 6 and Figure 8As shown, the main body 3011 is rotatably connected to the first bracket 101. The second bracket 102 includes a bracket body 1020 and a locking member 302 disposed on the bracket body. The locking member 302 is provided with a slot 3021, and the slot 3021 has an adjacent bottom wall surface 3021a and a side wall surface 3021b connected to the bottom wall surface 3021a. When the frame mechanism 10 is in the unfolded state, the locking part 3012 abuts against the side wall surface 3021b under the elastic force of the elastic member 303 to limit the angle of the locking part 3012 relative to the first bracket 101, so that the locking part 3012 can abut against the bottom wall surface 3021a of the slot 3021, thereby restricting the folding of the first bracket 101 and the second bracket 102 relative to each other. The user can manipulate the main body 3011 to drive the locking part 3012 to rotate relative to the first bracket 101, so that the locking part 3012 disengages from the slot 3021, thereby releasing the restriction on the relative rotation of the first bracket 101 and the second bracket 102.

[0077] For example, such as Figure 6 As shown, the main body 3011 includes an operating part 30111 and a connecting part 30112. The operating part 30111 is connected to the connecting part 30112, which is connected to the first bracket 101. The connecting part 30112 has a protruding locking part 3012. One end of the elastic member 303 is connected to the first bracket 101, and the other end is connected to the locking part 3012. When the frame mechanism 10 is in the unfolded state, the locking part 3012 engages with the slot 3021 under the elastic force of the elastic member 303. The two adjacent outer surfaces of the locking part 3012 abut against the bottom wall surface 3021a and the side wall surface 3021b of the slot 3021, respectively.

[0078] Optionally, the other end of the elastic element 303 is connected to the main body 3011 or the locking portion 3012. Preferably, the other end of the elastic element 303 is connected to the locking portion 3012 to reduce force transmission loss and to ensure that the locking portion 3012 is stably engaged in the slot 3021.

[0079] For example, such as Figure 1 , Figure 2 and Figure 6 As shown, the first support 101 includes a first support rod 1011, a second support rod 1012, and a connecting shaft 1013. The first support rod 1011 and the second support rod 1012 are arranged opposite to each other. The connecting shaft 1013 connects the first support rod 1011 and the second support rod 1012. The main body 3011 is rotatably connected to the connecting shaft 1013. The elastic element 303 includes a torsion spring. The torsion spring is sleeved on the outer periphery of the connecting shaft 1013, and the two arms of the torsion spring are respectively connected to the first support rod 1011 and the locking part 3012, so that the torsion spring can provide elastic force to the locking part 3012.

[0080] In some embodiments, the operating member 301 includes a main body 3011 and a locking portion 3012. The main body 3011 is rotatably connected to the first bracket 101, and the locking portion 3012 protrudes from the main body 3011. The first bracket 101 is also provided with a limiting portion. In the unfolded state, the main body 3011 rotates relative to the first bracket 101 under the action of elastic force until it abuts against the limiting portion, thereby limiting the angle of the operating member 301 relative to the first bracket 101. The locking member 302 can connect with the locking portion 3012 to limit the relative folding of the first bracket 101 and the second bracket 102.

[0081] like Figure 3 and Figure 4 As shown, in some embodiments, the plurality of supports 100 include a first support 101 and a second support 102, which are arranged adjacent to each other. A steering assembly 103 is rotatably connected to the first support 101. The transmission mechanism 20 includes a first transmission member 201, one end of which is rotatably connected to the steering assembly 103, and the other end of which is rotatably connected to the second support 102, so that when the first support 101 and the second support 102 rotate relative to each other, the steering assembly 103 and the first support 101 rotate relative to each other. Thus, the first transmission component 201, the first bracket 101, the second bracket 102, and the steering assembly 103 constitute a crank-rocker mechanism. When the first bracket 101 and the second bracket 102 rotate relative to each other to fold relative to each other, the steering assembly 103 and the first bracket 101 can rotate relative to each other to fold relative to each other. When the first bracket 101 and the second bracket 102 rotate relative to each other to unfold relative to each other, the steering assembly 103 and the first bracket 101 can rotate relative to each other to unfold relative to each other, thus achieving linkage.

[0082] Specifically, such as Figure 3 and Figure 4 As shown, the connection positions between the first transmission component 201 and the second bracket 102 and the first bracket 101 and the second bracket 102 are spaced apart, and the connection positions between the first transmission component 201 and the steering assembly 103 and the first bracket 101 and the steering assembly 103 are spaced apart.

[0083] For example, such as Figure 3 and Figure 4As shown, the steering assembly 103 includes a steering link 1031 and a handlebar 1032. A first bracket 101 and a first transmission member 201 are rotatably connected to the steering link 1031, and the steering link 1031 is rotatably connected to a first roller 41 on opposite sides along the Y direction. The handlebar 1032 is rotatably connected to the steering link 1031 and is drivenly connected to the first roller 41. A handle 1033 is provided at the end of the handlebar 1032 away from the steering link 1031. When the first bracket 101 and the second bracket 102 rotate relative to each other to fold, the first bracket 101 and the first transmission member 201 can drive the steering link 1031 and the first bracket 101 to rotate relative to each other, thereby causing the handlebar 1032 and the first bracket 101 to fold relative to each other.

[0084] In some embodiments, the mobile device further includes a seat assembly 104, a steering assembly 103, and a seat assembly 104, which are rotatably connected to two supports 100, respectively. A transmission mechanism 20 is also tractively connected to the seat assembly 104. When the supports 100 rotate relative to each other, the transmission mechanism 20 actuates, causing the supports 100 connected to the seat assembly 104 and the seat assembly 104 to rotate relative to each other. It is understood that when the supports 100 rotate relative to each other to fold relative to each other, the transmission mechanism 20 enables the supports 100 connected to the seat assembly 104 and the seat assembly 104 to rotate relative to each other, thus folding relative to each other; when the supports 100 rotate relative to each other to unfold relative to each other, the transmission mechanism 20 enables the supports 100 connected to the seat assembly 104 and the seat assembly 104 to rotate relative to each other, thus unfolding relative to each other. Thus, the addition of seat assembly 104 enables users to sit in and drive the mobile device, while the folding or unfolding of seat assembly 104 is achieved through transmission mechanism 20, thereby realizing the overall linkage folding or unfolding of frame mechanism 10.

[0085] It is worth noting that when the operating member 301 rotates relative to the bracket 100 connected to it to engage with at least one of the multiple brackets 100, restricting the relative rotation between the multiple brackets 100, the transmission mechanism 20 can also restrict the relative rotation between the bracket 100 connected to the seat assembly 104 and the seat assembly 104, so that the bracket 100 connected to the seat assembly 104 and the seat assembly 104 remain relatively extended.

[0086] like Figures 3 to 5As shown, in some embodiments, the seat assembly 104 includes a seat body 1041 and a seat bracket 1042. One end of the seat bracket 1042 is rotatably connected to at least one of a plurality of brackets 100, and the other end of the seat bracket 1042 is rotatably connected to the seat body 1041. The seat bracket 1042 is driveably connected to a transmission mechanism. The transmission mechanism 20 is capable of driving the brackets 100 connected to the seat bracket 1042 and the seat bracket 1042 to rotate relative to each other, as well as driving the seat body 1041 and the seat bracket 1042 to rotate relative to each other. Understandably, when the locking mechanism 30 restricts the relative rotation of the first bracket 101 and the second bracket 102, the transmission mechanism 20 can restrict the relative rotation of the bracket 100 connected to the seat bracket 1042 and the seat bracket 1042. The seat body 1041 can maintain the angle between itself and the seat bracket 1042 under the restriction of the seat bracket 1042. The transmission mechanism 20 is connected to the seat bracket 1042, which can simultaneously restrict the rotation of the seat bracket 1042 and the seat body 1041, simplifying the structure of the mobile device and reducing the weight of the mobile device.

[0087] Specifically, when the restriction on relative rotation between the multiple supports 100 is lifted, and the multiple supports 100 rotate relative to each other to fold relative to each other, the transmission mechanism 20 can drive the supports 100 connected to the seat support 1042 and the seat support 1042 to rotate relative to each other to fold relative to each other, and the seat support 1042 can drive the seat body 1041 to rotate relative to the seat support 1042 to fold relative to each other; when the multiple supports 100 rotate relative to each other to unfold relative to each other, the transmission mechanism 20 can drive the supports 100 connected to the seat support 1042 and the seat support 1042 to rotate relative to each other to unfold relative to each other, and the seat support 1042 can drive the seat body 1041 to rotate relative to the seat support 1042 to unfold relative to each other.

[0088] like Figures 3 to 5As shown, the seat support 1042 further includes a first crank 10421 and a first rocker arm 10422. One end of the first crank 10421 and one end of the first rocker arm 10422 are rotatably connected to the same support 100, and the other ends of the first crank 10421 and the first rocker arm 10422 are rotatably connected to the seat body 1041. The first crank 10421 is also driveably connected to the transmission mechanism 20. By forming a crank-rocker mechanism with a support 100, the seat support 1042, and the seat body 1041, when the transmission mechanism 20 drives the seat support 1042 to move, the seat support 1042 can drive the seat body 1041 to rotate relative to the seat support 1042. When the transmission mechanism 20 restricts the movement of the seat support 1042, the seat support 1042 can restrict the rotation of the seat body 1041 relative to the seat support 1042.

[0089] For example, such as Figure 1 and Figure 3 As shown, the seat bracket 1042 includes two support units 1042a. Each support unit 1042a includes a first crank 10421 and a first rocker arm 10422. The multiple brackets 100 include a second bracket 102. The two support units 1042a are located on opposite sides of the second bracket 102 along the Y direction to support the opposite sides of the seat body 1041 along the Y direction, thereby improving the stability of the seat body 1041 when the frame mechanism 10 is deployed and improving the safety of using the mobile device.

[0090] For example, such as Figure 3 As shown, the plurality of supports 100 includes a second support 102. The second support 102 includes a third support rod 1021 and a fourth support rod 1022 arranged at relative intervals. The first rocker arm 10422 and the first crank 10421 of one support unit 1042a are rotatably connected to the connecting seat on the third support rod 1021, respectively. The first rocker arm 10422 and the first crank 10421 of the other support unit 1042a are rotatably connected to the connecting seat on the fourth support rod 1022, respectively. The connection positions between the first crank 10421 and the connecting seat and between the first rocker arm 10422 and the connecting seat are spaced apart. The connection positions between the first crank 10421 and the seat body 1041 and between the first rocker arm 10422 and the connecting seat are also spaced apart.

[0091] like Figures 3 to 5 , Figure 9As shown, in some embodiments, the multiple supports 100 include a first support 101 and a second support 102, the first support 101 and the second support 102 are arranged adjacent to each other, one end of the seat support 1042 is rotatably connected to the second support 102, and the second support 102 is formed with a groove 1023. The transmission mechanism 20 includes a second transmission member 202 and a third transmission member 203. One end of the second transmission member 202 is rotatably connected to the first bracket 101, and the other end of the second transmission member 202 is rotatably and slidably connected to the slide groove 1023. One end of the third transmission member 203 is rotatably connected to the second transmission member 202, and the other end of the third transmission member 203 is rotatably connected to the seat assembly 104. Alternatively, the transmission mechanism 20 includes a first transmission member 201, a second transmission member 202, and a third transmission member 203. One end of the first transmission member 201 is rotatably connected to the steering assembly 103, and the other end of the first transmission member 201 is rotatably connected to the second bracket 102. One end of the second transmission member 202 is rotatably connected to the first transmission member 201 or the first bracket 101, and the other end of the second transmission member 202 is rotatably and slidably connected to the slide groove 1023. One end of the third transmission member 203 is rotatably connected to the second transmission member 202, and the other end of the third transmission member 203 is rotatably connected to the seat assembly 104. Understandably, the first support 101, the second support 102, and the second transmission member 202 constitute a crank-slider mechanism, or the first transmission member 201, the second support 102, and the second transmission member 202 constitute a crank-slider mechanism. Thus, when the first support 101 and the second support 102 rotate relative to each other to fold, the second transmission member 202 can be driven to move. The second transmission member 202 drives the seat assembly 104 through the third transmission member 203, so that the seat assembly 104 rotates relative to the second support 102 to fold. Moreover, the structure of the transmission mechanism 20 is relatively simple.

[0092] For example, such as Figure 6 As shown, one end of the first transmission member 201 is rotatably connected to the steering assembly 103, and the other end extends toward the second bracket 102, such that the other end of the first transmission member 201 is rotatably connected to the second bracket 102 and the second transmission member 202 respectively.

[0093] For example, such as Figure 9 As shown, the second transmission member 202 is provided with a rotating shaft 204, which is rotatable and slidably disposed in the slide groove 1023, so that the second transmission member 202 rotates and is slidably connected to the slide groove 1023. Alternatively, the second transmission member 202 is rotatably connected to a slider, which is slidably disposed in the slide groove 1023, so that the second transmission member 202 rotates and is slidably connected to the slide groove 1023.

[0094] For example, the second transmission member 202 is provided with a rotating shaft 204, which can be fixedly connected or rotatably connected to the second transmission member 202. The second transmission member 202 and the third transmission member 203 are rotatably connected through the rotating shaft 204, and the rotating shaft 204 can be rotatably and slidably disposed in the slide groove 1023 to simplify the structure of the transmission mechanism 20.

[0095] Specifically, such as Figure 3 As shown, when the frame mechanism 10 is in the unfolded state, one end of the third transmission member 203 is rotatably connected to the second transmission member 202, and the other end extends upward away from the second bracket 102 and is rotatably connected to the seat bracket 1042. The third transmission member 203 can restrict the seat bracket 1042 from rotating relative to the second bracket 102. At the same time, the third transmission member 203 can support the seat bracket 1042, so that the seat bracket 1042 can more stably support the seat body 1041.

[0096] For example, such as Figures 3 to 5 , Figure 9 As shown, the seat assembly 104 includes a seat body 1041 and a seat bracket 1042. The seat bracket 1042 includes a first crank 10421 and a first rocker arm 10422. One end of the first crank 10421 and the first rocker arm 10422 is rotatably connected to a second bracket 102, and the other end of the first crank 10421 and the first rocker arm 10422 is rotatably connected to the seat body 1041. The first crank 10421 is located on the side of the first rocker arm 10422 closer to the first bracket 101. One end of the second transmission component 202 is rotatably connected to the first transmission component 201, and the other end of the second transmission component 202 is provided with a rotating shaft 204. One end of the second transmission component 202 and the third transmission component 203 are rotatably connected through the rotating shaft 204. The other end of the third transmission component 203 is rotatably connected to the first crank 10421. The second bracket 102 forms a sliding groove 1023, which is located on the side of the seat bracket 1042 near the first bracket 101. The rotating shaft 204 is rotatable and slidable in the sliding groove 1023. When the first support 101 and the second support 102 rotate relative to each other to fold, the first transmission member 201 can drive one end of the second transmission member 202 to move upward. The rotating shaft 204 located at the other end of the second transmission member 202 rotates in the slide groove 1023 and slides towards the side where the first support 101 is located. The rotating shaft 204 drives one end of the third transmission member 203 to move closer to the first support 101. The other end of the third transmission member 203 drives the first crank 10421 to rotate relative to the second support 102, so that the seat support 1042 tilts towards the side where the first support 101 is located, realizing the relative folding of the seat support 1042 and the second support 102. The first crank 10421 drives the side of the seat body 1041 away from the first support 101 to tilt towards the first rocker arm 10422, realizing the relative folding of the seat body 1041 and the seat support 1042.

[0097] like Figure 9 As shown, in some embodiments, the slide 1023 includes a first groove 1023a and a second groove 1023b, with the second groove 1023b bent relative to the first groove 1023a. The second transmission member 202 is provided with a rotating shaft 204, which is slidably and rotatably disposed in the slide 1023. When the frame mechanism 10 is in the unfolded state, the rotating shaft 204 is engaged with the first groove 1023a. It can be understood that, based on the locking mechanism 30 restricting the relative rotation of the first bracket 101 and the second bracket 102 and restricting the movement of the transmission mechanism 20, the engaging of the rotating shaft 204 with the first groove 1023a further stabilizes and restricts the movement of the transmission mechanism 20, making the frame mechanism 10 more stably in the unfolded state and improving driving safety.

[0098] For example, the second groove 1023b can be an arc-shaped groove or a straight groove, which can be adjusted according to the actual situation.

[0099] Furthermore, when the frame mechanism 10 is in the unfolded state, one end of the third transmission member 203 is rotatably connected to the second transmission member 202, and the other end extends upward and is rotatably connected to the seat bracket 1042. The third transmission member 203 can support the seat bracket 1042, and the reaction force exerted by the seat bracket 1042 on the third transmission member 203 can be transmitted to the rotating shaft 204, so that the rotating shaft 204 is stably engaged in the first groove 1023a.

[0100] like Figure 1 As shown, in some embodiments, the mobile device further includes a drive mechanism 40, a first roller 41 and a second roller 42. The first roller 41 is tractively connected to the steering assembly 103, and the second roller 42 is rotatably connected to one of the plurality of brackets 100 connected to the seat assembly 104 and tractively connected to the drive mechanism 40. The drive mechanism 40 can drive the second roller 42 to roll, thereby driving the mobile device to move.

[0101] For example, such as Figure 1 As shown, there are two first rollers 41 and two second rollers 42. The two first rollers 41 are located on opposite sides of the steering assembly 103 along the Y direction. The multiple brackets 100 include a second bracket 102. The seat assembly 104 is rotatably connected to the second bracket 102. The two second rollers 42 are located on opposite sides of the second bracket 102 along the Y direction, so that the mobile device can move smoothly.

[0102] For example, the drive mechanism 40 includes a rotary motor.

[0103] For example, the drive mechanism 40 is located between the two second rollers 42, and the two opposite ends of the rotary motor have output shafts. The two output shafts are respectively driven and connected to the two second rollers 42 to simplify the connection structure between the drive mechanism 40 and the two second rollers 42.

[0104] For example, the drive mechanism 40 includes a rotary motor and a transmission assembly. The rotary motor has an output shaft that is driveably connected to the transmission assembly, which is driveably connected to two second rollers 42.

[0105] like Figure 1 As shown, in some embodiments, the steering assembly 103 includes a steering link 1031 and a handlebar 1032. A first bracket 101 is rotatably connected to the steering link 1031, a first roller 41 is rotatably connected to the steering link 1031, and a transmission assembly is drive-connected to the steering link 1031. The handlebar 1032 is rotatably connected to the steering link 1031 and drive-connected to the first roller 41. A handle 1033 is provided at the end of the handlebar 1032 away from the steering link 1031. It is understood that when driving the mobile device, the user can hold the handlebar 1033 to control the rotation of the handlebar 1032 relative to the steering link 1031, thereby rotating the first roller 41 to achieve steering and control the direction of travel of the mobile device.

[0106] Furthermore, the handle 1032 is a telescopic rod to adjust the height of the handle 1033, so that the position of the handle 1033 can be adapted to different users, thereby improving the user experience of mobile devices.

[0107] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
