Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a chassis mechanism and a vehicle. Background Technology

[0002] To facilitate transport and storage, some mobility scooters can be folded. For example, the seat and chassis of a mobility scooter can be folded or unfolded to save space.

[0003] To support and secure the seat, the scooter is also designed with a movable connecting rod. One end of the rod connects to the seat's support frame, while the other end connects to the chassis, providing support for the seat.

[0004] However, when the seat is unfolded and in use, the two ends of the connecting rod are subjected to concentrated force, directly bearing the large weight applied by the seat, which can easily cause the connecting rod to bend under stress and affect its service life. Utility Model Content

[0005] This application provides a chassis mechanism and vehicle to solve the problem of excessive stress and easy bending caused by the stress concentration of the linkage in existing mobility vehicles.

[0006] In a first aspect, this application provides a chassis mechanism, including a chassis, a support frame, a connector, and an abutment portion. One end of the support frame is rotatably connected to the chassis. One end of the connector is movably connected to the chassis, and the other end is movably connected to the support frame. The abutment portion is connected to the chassis. When the other end of the support frame is rotated to an open position away from the chassis, the two ends of the connector are connected to the abutment portion.

[0007] The chassis mechanism provided in this application allows the other end of the support frame to be connected to the seat mechanism. Since one end of the support frame is rotatably connected to the chassis, the support frame can rotate relative to the chassis, thereby causing the seat mechanism to rotate relative to the chassis, enabling the seat mechanism to open and retract. Because one end of the connector is movably connected to the chassis and the other end is movably connected to the support frame, the connector can move relative to the support frame to unfold or retract when the support frame rotates, ensuring smooth relative rotation between the support frame and the chassis. Since both ends of the connector can connect to the abutment portion, the connection points between the connector and the abutment portion provide force support to the support frame, thereby dispersing the overall force on the connector, reducing force concentration, and thus lowering the probability of the connector bending under stress.

[0008] In some embodiments, one end of the connector is located on the periphery of the chassis and is movably connected to the chassis. The abutment portion is located on the periphery of the chassis and is connected to the chassis.

[0009] In some embodiments, the connector includes a first connecting portion and a second connecting portion. One end of the first connecting portion is movably connected to the chassis. One end of the second connecting portion is connected to the other end of the first connecting portion, and the other end of the second connecting portion is movably connected to the support frame. The first connecting portion and the second connecting portion form an angle, and when the support frame is in the open position, the first connecting portion and the second connecting portion form protrusions facing towards the abutment portion.

[0010] In some embodiments, the connector further includes a snap-fit ​​portion. The snap-fit ​​portion connects to either the first connecting portion or the second connecting portion. The snap-fit ​​portion is used to engage with the abutment portion.

[0011] In some embodiments, the snap-fit ​​portion has a first surface, and the abutment portion has a second surface. The snap-fit ​​portion is connected to the first connecting portion, one side of the first surface is connected to the first connecting portion, and the plane containing the first surface intersects the extending direction of the first connecting portion. Alternatively, the snap-fit ​​portion is connected to the second connecting portion, one side of the first surface is connected to the second connecting portion, and the plane containing the first surface intersects the extending direction of the second connecting portion.

[0012] In some embodiments, the chassis includes a first chassis and a second chassis. The second chassis is located on one side of the first chassis, is rotatably connected to the first chassis, and is rotatably connected to one end of the support frame.

[0013] In some embodiments, the rotation axes of the first chassis and the second chassis are parallel to the rotation axis of the support frame.

[0014] In some embodiments, one end of the connector is rotatably connected to the first chassis, and the axis of rotation is located outside the axis of rotation of the first chassis and the second chassis, and parallel to the axis of rotation of the first chassis and the second chassis. The other end of the connector is rotatably connected to the support frame, and the axis of rotation is located outside the axis of rotation of the second chassis and the support frame, and parallel to the axis of rotation of the second chassis and the support frame.

[0015] In some embodiments, one end of the connector has a first connecting hole. The first chassis has a first connecting post, which passes through the first connecting hole.

[0016] In some embodiments, the other end of the connector has a second connecting hole, and the support frame has a third connecting hole. The chassis mechanism also includes fasteners. The fasteners pass through the second and third connecting holes.

[0017] In some embodiments, the chassis further includes a third chassis. The third chassis is located on the side of the first chassis away from the second chassis. The third chassis is rotatably connected to the first chassis, and its axis of rotation is parallel to the axes of rotation of the first and second chassis. The chassis mechanism also includes a transmission member. One end of the transmission member is rotatably connected to the third chassis, and its axis of rotation is located outside the axis of rotation of the third chassis. The other end of the transmission member is rotatably connected to the second chassis, and its axis of rotation is located outside the axis of rotation of the second chassis. The axes of rotation at both ends of the transmission member are parallel to the axes of rotation of the first and second chassis.

[0018] Secondly, embodiments of this application provide a vehicle including any of the chassis mechanisms described in the first aspect.

[0019] Since the vehicle provided in this application includes any of the chassis mechanisms described in the first aspect, it can solve the same technical problems as the chassis mechanism and achieve the same technical effects, so it will not be described in detail here.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element.

[0025] In the following description, the terms "first," "second," etc., are used for descriptive convenience only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0026] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed mechanical connection, a detachable mechanical connection, or an integral part; or, "connection" may be a direct connection or an indirect connection through an intermediate medium.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] This application provides a vehicle, which can be of different types of personal transportation. For example, such as... Figure 1 As shown, Figure 1This is a structural schematic diagram of a vehicle 1000 provided in an embodiment of this application. The vehicle 1000 can be a four-wheeled mobility scooter.

[0029] like Figure 1 As shown, the vehicle 1000 may include a chassis mechanism 100, a steering mechanism 200, and a seat mechanism 300. The chassis mechanism 100 can serve as a support mechanism and a drive mechanism for the vehicle 1000, enabling the vehicle 1000 to drive.

[0030] The steering mechanism 200 can be connected to the chassis mechanism 100, allowing the user to adjust the forward direction of the vehicle 1000 to achieve steering. It is understood that the specific composition of the steering mechanism 200 can be designed according to actual conditions, and no further limitations are made here.

[0031] The seat mechanism 300 can be mounted on the chassis mechanism 100. The seat mechanism 300 provides a seating position for the user, facilitating the user's operation of the vehicle 1000. Similarly, the specific composition of the seat mechanism 300 can be designed according to actual conditions, and no further limitations are made here.

[0032] The chassis mechanism 100 provided in the embodiments of this application will be further described below. For example... Figure 2 As shown, Figure 2 for Figure 1 The diagram shows the vehicle 1000 from another angle. The chassis mechanism 100 may include a chassis 10, a support frame 20, and a connector 30. One end of the support frame 20 is rotatably connected to the chassis 10. The other end of the support frame 20 is connected to a seat mechanism 300, which can be mounted on the chassis mechanism 100 via the support frame 20.

[0033] Since one end of the support frame 20 is rotatably connected to the chassis 10, the support frame 20 can rotate relative to the chassis 10, thereby driving the seat mechanism 300 to rotate relative to the chassis 10, realizing the opening and retraction of the seat mechanism 300. The support frame 20 can have an open position and a retracted position.

[0034] When the other end of the support frame 20 moves away from the chassis 10, the support frame 20 can rotate to the open position. At this time, the seat mechanism 300 is in the unfolded state, providing a seating position for the user. When the other end of the support frame 20 moves towards the chassis 10, the support frame 20 can rotate to the retracted position. At this time, the entire seat mechanism 300 can be close to the chassis 10 and in the retracted state, saving space.

[0035] For example, such as Figure 2As shown, as the other end of the support frame 20 moves away from the chassis 10, the seat mechanism 300 gradually opens and is positioned above the chassis 10, providing a seating position for the user. As the other end of the support frame 20 moves closer to the chassis 10, the chassis 10 and the seat mechanism 300 gradually move closer together, and the two can fold together to save space.

[0036] One end of the connector 30 is movably connected to the chassis 10, and the other end is movably connected to the support frame 20. In this way, when the support frame 20 rotates, the connector 30 can move relative to the chassis 10 to extend or retract, ensuring that the support frame 20 and the chassis 10 can rotate smoothly relative to each other.

[0037] Since the two ends of the connector 30 are connected to the support frame 20 and the chassis 10 respectively, when the other end of the support frame 20 is rotated to the open position away from the chassis 10, the two ends of the connector 30 are subjected to force and can play a supporting role.

[0038] To reduce the stress on the end of connector 30, such as Figure 2 As shown, the chassis mechanism 100 may further include an abutment portion 40. The abutment portion 40 is connected to the chassis 10. Wherein, as... Figure 2 As shown, when the other end of the support frame 20 is rotated to the open position in a direction away from the chassis 10, the two ends of the connector 30 are connected to the abutment portion 40.

[0039] In this way, since the two ends of the connector 30 can be connected to the abutment part 40, the connection point between the connector 30 and the abutment part 40 can provide force support to the support frame 20, thereby decomposing the overall force on the connector 30, reducing the force concentration on the connector 30, and thus reducing the probability of the connector 30 bending under force.

[0040] Understandably, the connection method between the abutment part 40 and the chassis 10 can be designed according to the actual situation. As an example, the abutment part 40 can be integrally formed with the chassis 10. Alternatively, the abutment part 40 can also be installed on the chassis 10 by a fixed connection or a detachable connection, depending on the actual situation.

[0041] Furthermore, the connection between the two ends of the connector 30 and the abutment portion 40 can take different forms. In some embodiments, the two ends of the connector 30 can be directly abutted against the abutment portion 40 to achieve the connection between the two.

[0042] Alternatively, in other embodiments, the abutment portion 40 can also achieve a relatively fixed connection between the abutment portion 40 and the connector 30 by means of snap-fit ​​or other methods.

[0043] In some embodiments, such as Figure 2 As shown, one end of the connector 30 can be located on the periphery of the chassis 10 and movably connected to the chassis 10. Correspondingly, the abutment portion 40 can also be located on the periphery of the chassis 10 and connected to the chassis 10. In this way, the connector 30 can move on the periphery of the chassis 10 and abut against the abutment portion 40. By setting the connection position of the connector 30 on the periphery of the chassis 10, the movement of the connector 30 can be facilitated, as can the abutment portion 40.

[0044] Of course, the abutment 40 and the connector 30 can also be located in other positions. For example, the abutment 40 can also be located at... Figure 2 On the upper side of the chassis 10 shown, one end of the connector 30 can be directly connected to the corresponding position of the chassis 10, so that the two ends of the connector 30 can abut against the abutment part 40.

[0045] In some embodiments, the number of abutment portions 40 and connectors 30 can both be multiple. The multiple abutment portions 40 can be spaced apart around the periphery of the chassis 10, and one end of the multiple connectors 30 can be movably connected to the periphery of the chassis at intervals.

[0046] For example, there may be two abutment portions 40. The two abutment portions 40 are located on opposite sides of the chassis 10. Correspondingly, there are also two connectors 30, one end of which is movably connected to the opposite sides of the chassis 10 where the abutment portions 40 are provided.

[0047] Of course, in some other embodiments, the number of abutting part 40 and connector 30 may also be one. The specific number of both can be set according to the actual situation. This is only used as an example for illustration and is not further limited.

[0048] In some embodiments, such as Figure 3 As shown, Figure 3 for Figure 2 The enlarged view at point A shows that the connector 30 may include a first connecting portion 31 and a second connecting portion 32. One end of the first connecting portion 31 can be movably connected to the chassis 10. One end of the second connecting portion 32 can be connected to the other end of the first connecting portion 31, and the other end of the second connecting portion 32 can be movably connected to the support frame 20.

[0049] The first connecting portion 31 and the second connecting portion 32 can form an included angle, and when the support frame 20 is in the open position, the first connecting portion 31 and the second connecting portion 32 form a protrusion facing towards the abutment portion 40. Thus, the first connecting portion 31 and the second connecting portion 32 can form a V-shaped structure, and the first connecting portion 31 and the second connecting portion 32 can also change the force transmission path, decompose the force to generate component forces, and thereby improve the structural strength and stability of the connector 30.

[0050] The manufacturing method of the first connecting part 31 and the second connecting part 32 can be selected according to the actual situation. For example, the first connecting part 31 and the second connecting part 32 can be integrally formed. Alternatively, the first connecting part 31 and the second connecting part 32 can be manufactured separately and then connected together to form the connector 30.

[0051] Of course, the connector 30 can also have other configurations. In some embodiments, the connector 30 can also be a straight strip structure. In this case, the connector 30 has a simple structure and is easier to manufacture.

[0052] In some embodiments, such as Figure 3 As shown, the connector 30 may further include a snap-fit ​​portion 33. The snap-fit ​​portion 33 is connected to either the first connector 31 or the second connector 32. The snap-fit ​​portion 33 is used to snap into the abutment portion 40.

[0053] In this way, the snap-fitting part 33 can improve the stability of the abutment between the contact part 40 and the connector 30, ensuring the abutment effect. Of course, in some other embodiments, the connector 30 may not include the snap-fitting part 33. In this case, the contact part 40 may only abut against the first connecting part 31 or the second connecting part 32.

[0054] It is understandable that the connection position of the snap-fit ​​part 33 can be set according to the abutment position of the abutment part 40 and the connector 30. For example, as Figure 3 As shown, the snap-fit ​​portion 33 can be connected to the second connecting portion 32, and the abutting portion 40 abuts against the second connecting portion 32. Of course, in some other embodiments, the snap-fit ​​portion 33 can also be connected to the first connecting portion 31, and the abutting portion 40 abuts against the first connecting portion 31.

[0055] Furthermore, by way of example, the snap-fit ​​portion 33 may also be integrally formed with the first connecting portion 31 and the second connecting portion 32. Alternatively, the snap-fit ​​portion 33 may be formed separately and then connected to the first connecting portion 31 or the second connecting portion 32. The method of forming the snap-fit ​​portion 33 can be selected according to the actual situation; this is only an example and is not further limited.

[0056] In some embodiments, such as Figure 4 As shown, Figure 4 for Figure 3In the enlarged view at point B, the latching portion 33 may have a first surface 331. The abutting portion 40 may have a second surface 401. The second surface 401 can be used to fit against the first surface 331. When the latching portion 33 is connected to the first connecting portion 31, one side of the first surface 331 can connect to the first connecting portion 31, and the plane containing the first surface 331 can intersect the extending direction of the first connecting portion 31. Similarly, when the latching portion 33 is connected to the second connecting portion 32, one side of the first surface 331 can connect to the second connecting portion 32, and the plane containing the first surface 331 can intersect the extending direction of the second connecting portion 32.

[0057] Thus, as Figure 4 As shown, the first surface 331 and the second surface 401 can be in contact with each other, and forces can be generated between them. Furthermore, the first surface 331 and the second surface 401 are in surface contact, resulting in more uniform force distribution and avoiding the problem of force concentration.

[0058] It is understandable that the specific shapes of the latching part 33 and the abutting part 40 can be designed according to actual conditions. For example, the latching part 33 can be a block structure similar to a hook. Correspondingly, the abutting part 40 can be a block structure with an inclined second surface 401.

[0059] Of course, the engaging portion 33 and the abutting portion 40 can also make contact in other ways. In some other embodiments, the engaging portion 33 and the abutting portion 40 can also be in line contact. For example, the abutting portion 40 can be a cylindrical structure. In this case, the abutting portion 40 and the engaging portion 33 can be in line contact.

[0060] To enable the chassis mechanism 100 to be further folded, in some embodiments, such as Figure 5 As shown, Figure 5 This is a partial schematic diagram of a vehicle 1000 provided in an embodiment of this application. The chassis 10 may include a first chassis 11 and a second chassis 12. The second chassis 12 is located on one side of the first chassis 11, and the second chassis 12 is rotatably connected to the first chassis 11. The second chassis 12 is also rotatably connected to one end of the support frame 20.

[0061] Therefore, the first chassis 11 and the second chassis 12 can rotate relative to each other to fold or unfold, further reducing the space occupied by the chassis mechanism 100 when folded. Of course, in some other embodiments, the chassis 10 may also include only the first chassis 11 or the second chassis 12.

[0062] In some embodiments, the rotation axes of the first chassis 11 and the second chassis 12 are parallel to the rotation axis of the support frame 20. Because their rotation axes are parallel, they can be folded in the same direction, resulting in a more compact structure and a smaller space footprint after folding.

[0063] Of course, in other embodiments, the rotation axes of the first chassis 11 and the second chassis 12 may also intersect the rotation axis of the support frame 20. In this case, the folding directions of the first chassis 11 and the second chassis 12 may be different from those of the support frame 20.

[0064] Based on the above solution, in order to achieve the movable connection between the two ends of the connector 30, in some embodiments, such as Figure 5 As shown, one end of the connector 30 can be rotatably connected to the first chassis 11, and its rotation axis is located outside the rotation axes of the first chassis 11 and the second chassis 12, and is parallel to the rotation axes of the first chassis 11 and the second chassis 12. The other end of the connector 30 can be rotatably connected to the support frame 20, and its rotation axis is located outside the rotation axes of the second chassis 12 and the support frame 20, and is parallel to the rotation axes of the second chassis 12 and the support frame 20.

[0065] Therefore, when the first chassis 11 and the second chassis 12 rotate relative to each other, one end of the connecting member 30 can rotate relative to the first chassis 11. At the same time, since the rotation axis of one end of the connecting member 30 is located outside the rotation axis of the first chassis 11 and the second chassis 12, the rotation of the first chassis 11 will also cause the position of one end of the connecting member 30 to change.

[0066] Similarly, when the support frame 20 and the second chassis 12 rotate relative to each other, the other end of the connector 30 can rotate relative to the support frame 20. Simultaneously, since the axis of rotation of the other end of the connector 30 is located outside the axes of rotation of the second chassis 12 and the support frame 20, the rotation of the support frame 20 will also cause a change in the position of the other end of the connector 30. Therefore, the connector 30 can be extended or retracted during the movement of the first chassis 11 and the support frame 20.

[0067] It is understandable that when the connector 30 includes the snap-fit ​​part 33, by setting the connection positions at both ends of the connector 30 and the shape of the connector 30, the connector 30 can smoothly snap the snap-fit ​​part 33 into or separate from the abutment part 40 during the rotation of the first chassis 11 and the support frame 20.

[0068] Furthermore, it is understood that the movable connection method of the connector 30 can be designed according to the actual situation, as long as the support frame 20 can rotate smoothly. For example, in some other embodiments, the two ends of the connector 30 can also be movably connected to the support frame 20 and the chassis 10 by sliding connection. By sliding the connector 30 relative to the chassis 10 and the support frame 20, the connector 30 can also be unfolded or retracted as the support frame 20 and the chassis 10 rotate.

[0069] To achieve a rotatable connection between the connector 30 and the first chassis 11, in some embodiments, such as... Figure 6 As shown, Figure 6 for Figure 5 A magnified view from another angle shows that the first chassis 11 has a first connecting post 111, and one end of the connector 30 has a first connecting hole (not shown in the figure). The first connecting post 111 passes through the first connecting hole. Thus, through the cooperation between the first connecting hole and the first connecting post 111, a rotatable connection between the connector 30 and the first chassis 11 can be achieved.

[0070] Of course, the connector 30 and the first chassis 11 can also be rotatably connected in other ways. For example, one end of the connector 30 can have a columnar structure. Correspondingly, the first chassis 11 can have a corresponding hole structure.

[0071] Similarly, in order to achieve a rotatable connection between the connector 30 and the support frame 20, in some embodiments, such as Figure 7 As shown, Figure 7 This is a partially enlarged view of the connector 30 at its connection with the support frame 20. The other end of the connector 30 has a second connecting hole (not shown in the figure), and the support frame 20 has a third connecting hole (not shown in the figure). The chassis mechanism 100 also includes a fastener 50. The fastener 50 passes through the second and third connecting holes.

[0072] Therefore, by engaging the second and third connecting holes with the fastener 50, the connector 30 can rotate relative to the support frame 20. For example, the fastener 50 includes a bolt and a nut. The bolt passes through the second and third connecting holes. The nut is threadedly connected to the bolt.

[0073] In some embodiments, such as Figure 5 As shown, chassis 10 also includes a third chassis 13. The third chassis 13 is located on the side of the first chassis 11 away from the second chassis 12. The third chassis 13 is rotatably connected to the first chassis 11, and its axis of rotation is parallel to the axes of rotation of the first chassis 11 and the second chassis 12.

[0074] Among them, such as Figure 5As shown, the third chassis 13 can be connected to the steering mechanism 200. Thus, since the third chassis 13 and the first chassis 11 are rotatably connected, the third chassis 13 can be folded or unfolded, thereby causing the steering mechanism 200 to fold or unfold, further reducing the space occupied by the vehicle 1000 when folded.

[0075] The chassis mechanism 100 also includes a transmission member 60. One end of the transmission member 60 is rotatably connected to the third chassis 13, and its rotation axis is located outside the rotation axis of the third chassis 13. The other end of the transmission member 60 is rotatably connected to the second chassis 12, and its rotation axis is located outside the rotation axis of the second chassis 12. The rotation axes at both ends of the transmission member 60 are parallel to the rotation axes of the first chassis 11 and the second chassis 12.

[0076] Therefore, since the two ends of the transmission component 60 are located outside the rotation axes of the third chassis 13 and the second chassis 12 respectively, when the third chassis 13 and the first chassis 11 rotate, the transmission component 60 can be driven to unfold or retract. In addition, the transmission component 60 can also realize the linkage connection between the third chassis 13 and the first chassis 11.

[0077] Based on the above embodiments, such as Figure 8 and Figure 9 As shown, Figure 8 for Figure 2 A schematic diagram of the mechanism for folding the vehicle 100 shown. Figure 9 for Figure 2 The diagram shows the structure of vehicle 100 in a folded state. During folding, the first chassis 11, the second chassis 12, and the support frame 20 can rotate relative to each other. During this process, the connecting piece 30 can separate from the abutment part 40. Furthermore, the third chassis 13 can also rotate relative to the first chassis 11, ultimately allowing vehicle 1000 to fold into its folded state. Figure 9 The state shown.

[0078] Of course, in some other embodiments, the chassis 10 may only include a first chassis 11 and a second chassis 12. In this case, the steering mechanism 200 can be connected to the first chassis 11. In order to realize the folding function of the steering mechanism 200, in some embodiments, the steering mechanism 200 can be rotatably connected to the first chassis 11.
