[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners.
[0026] This embodiment provides a wheel steering structure with a shock absorption function, as Figures 1 to 6As shown, it includes a bottom tube 1, a connecting piece 2, a rotating shaft 3, an elastic piece 5, and a driving piece 6; both ends of the bottom tube 1 are respectively fixedly provided with a connecting piece 2, and each of the two connecting pieces 2 is provided with a rotating shaft 3. Each of the two rotating shafts 3 is provided with a mounting seat 4 that slides along the axis direction of the rotating shaft 3. The two mounting seats 4 are used to mount wheels. The connecting piece 2 and the mounting seat 4 restrict the mounting seat 4 from rotating around the axis of the rotating shaft 3 by means of a limiting block 41 cooperating with a limiting groove 21. The limiting block 41 slides longitudinally in the limiting groove 21, and an elastic piece 5 is provided on the sliding path of the mounting seat 4 to achieve shock absorption; one end of the driving piece 6 is fixedly arranged in the middle section of the bottom tube 1. One end of the driving piece 6 is provided with a rotating part 60, and the rotating part 60 is used for rotatably connecting to an external object. The other end of the driving piece 6 is provided with a driving part, and the driving part is used to control the bottom tube 1 to rotate relative to the external object through the rotating part 60 to drive the two wheels to rotate synchronously.
[0027] In this embodiment, the connecting piece 2 and the mounting seat 4 can only move longitudinally by means of the limiting block 41 cooperating with the limiting groove 21, avoiding the mounting seat 4 from rotating around the axis of the rotating shaft 3. During the vehicle driving process, the connecting piece 2 and the mounting seat 4 can effectively shock-absorb the wheel steering structure through the elastic piece 5, thereby extending the service life. And when the driving part at the other end of the driving piece 6 controls the bottom tube 1 to rotate relative to the external object through the rotating part 60, the mounting seat 4 cannot rotate around the axis of the rotating shaft 3, which also ensures that the two wheels at both ends of the bottom tube 1 can rotate synchronously, with a simple structure. In this embodiment, the connecting piece 2 and the mounting seat 4 move longitudinally by means of the limiting block 41 cooperating with the limiting groove 21, and an elastic piece 5 is arranged on the movement path of the mounting seat 4 for shock absorption, improving the service life of the wheel steering structure and the synchronism during wheel steering, enabling the vehicle to adapt to a more complex driving environment.
[0028] As Figure 1 、 Figure 2 and Figure 4 shown, the connecting piece 2 of this embodiment is a U-shaped frame 20. The vertical plates of the two U-shaped frames 20 are respectively fixed at both ends of the bottom tube 1. The open ends between the horizontal plates of the two U-shaped frames 20 face the wheels, making the wheels more stable when bearing forces in the vertical and horizontal directions after installation, ensuring the stability during vehicle driving. The rotating shaft 3 is arranged between the two horizontal plates of the U-shaped frame 20, and the axis of the rotating shaft 3 is perpendicular to the axis of the bottom tube 1, ensuring that the wheels are perpendicular to the ground after installation and can move along the axial direction of the rotating shaft 3 through the mounting seat 4, facilitating the arrangement of the elastic piece 5 between the mounting seat 4 and the horizontal plate to achieve the shock absorption effect.
[0029] As Figure 2 and Figure 4As shown, the vertical plate of the U-shaped frame 20 is longitudinally provided with a limiting groove 21, and the mounting seat 4 is provided with a limiting block 41 at a position matching the limiting groove 21, and the sliding direction of the limiting block 41 in the limiting groove 21 is perpendicular to the axis of the bottom tube 1. In this embodiment, the limiting groove 21 cooperates with the limiting block 41 to limit the movement range of the mounting seat 4 on the U-shaped frame 20, so that the mounting seat 4 can only slide longitudinally along the rotating shaft 3 relative to the U-shaped frame 20, which is beneficial to the synchronous steering of the two wheels and has a simple structure. In other embodiments, it is also possible to longitudinally convexly provide the limiting block 41 on the vertical plate of the U-shaped frame 20, and longitudinally provide the limiting groove 21 on the mounting seat 4.
[0030] like Figure 2 and Figure 4 As shown, the elastic member 5 is a buffer spring 50, and the mounting seat 4 includes a sleeve 42. The sleeve 42 and the buffer spring 50 are sleeved on the rotating shaft 3, and the buffer spring 50 is located between the sleeve 42 and the cross plate of the U-shaped frame 20. The elastic member 5 of this embodiment adopts a buffer spring 50, and the buffer spring 50 is located between the cross plate above the U-shaped frame 20 and the sleeve 42, which can further improve the stability of the wheel running. When the wheel encounters a bumpy or uneven road surface, the buffer spring 50 can undergo elastic deformation, thereby reducing the impact on the mounting seat 4 and the rotating shaft 3 and improving the service life. The structure of the buffer spring 50 and the sleeve 42 is relatively simple and easy to install and disassemble. When maintenance or replacement of parts is required, the buffer spring 50 and the sleeve 42 can be easily removed for inspection and replacement.
[0031] like Figure 2 As shown, the mounting seat 4 of this embodiment further includes a mounting shaft 43, and two mounting shafts 43 are radially protruded from the two sleeves 42, and the axes of the two mounting shafts 43 are parallel to the axis of the bottom tube 1, and the two wheels are fixedly mounted on the two mounting shafts 43. The mounting shafts 43 provide a stable support point for the wheel, so that the wheel can be firmly mounted on the mounting seat 4, and it is not easy to shake or fall off, which is convenient for users to load and unload. The axis of the mounting shaft 43 is parallel to the axis of the bottom tube 1, which is conducive to the synchronous steering of the wheel.
[0032] like Figures 1 to 3 As shown, the invention also includes a mounting frame 7, which is arranged on the bottom tube 1, and one end of the driving member 6 is fixedly arranged on the mounting frame 7, and is located above the middle section of the bottom tube 1. The mounting frame 7 of this embodiment avoids direct interference between the wheel and external objects, and is more flexible during installation. When dealing with different driving environments, it is only necessary to adjust the height of the mounting frame 7 to install wheels of different sizes, thereby enhancing versatility and adaptability and meeting different usage requirements.
[0033] like Figures 1 to 3 , Figure 5 and Figure 6As shown, the rotating part 60 includes a steering shaft 600, a bearing 620 and a bearing seat 630. The steering shaft 600 is fixedly arranged at one end of the driving member 6. The axial hole 610 of the steering shaft 600 passes through one end of the driving member 6. The inner ring of the bearing 620 is fixedly sleeved on the steering shaft 600. The bearing seat 630 is provided with a accommodating cavity 640 matching the bearing 620. The bearing 620 is arranged in the accommodating cavity 640. The outer ring of the bearing 620 is fixedly pressed against the cavity wall of the accommodating cavity 640. The bearing seat 630 is used for fixed installation on an external object.
[0034] A steering shaft 600 is fixedly provided at one end of the driving member 6 of the present embodiment, the inner ring of the bearing 620 is fixedly sleeved on the outer periphery of the steering shaft 600, and the bearing seat 630 is provided with a receiving cavity 640 for installing the bearing 620. The shape of the receiving cavity 640 matches the shape of the bearing 620, and the outer periphery of the bearing 620 is fixedly pressed against the cavity wall of the receiving cavity 640. Therefore, when the driving part at the other end of the driving member 6 rotates, the steering shaft 600 at one end of the driving member 6 can rotate on the bearing seat 630 through the bearing 620, and the bearing seat 630 is fixedly installed on an external object. Therefore, the two wheels of the bottom tube 1 rotate synchronously relative to the external object, with a simple structure and ingenious design.
[0035] like Figure 5 and Figure 6 As shown, it also includes a fixing bolt (not shown in the figure), and a first threaded through hole 650 is opened on the bearing seat 630. The fixing bolt passes through the first threaded through hole 650 and abuts against the outer ring of the bearing 620 in the accommodating cavity 640, thereby fixing the bearing 620 on the bearing seat 630. In this embodiment, the bearing 620 is firmly fixed on the bearing seat 630 by the fixing bolt and the first threaded through hole 650, so as to prevent the bearing 620 from displacement or shaking during the rotation process, and the fixing bolt makes the assembly and disassembly process of the bearing 620 simpler and faster.
[0036] like Figures 2 to 6 As shown, it also includes a slide seat 8 and a positioning member 9, the slide seat 8 is fixedly set on an external object, the bearing seat 630 is slidably set in the slide seat 8, the slide seat 8 is provided with a positioning portion 80, and the bearing seat 630 is fixed to the slide seat 8 by the positioning member 9 and the positioning portion 80. The bearing seat 630 of this embodiment can slide in the slide seat 8, the slide seat 8 and the bearing seat 630 are matched in structure, and the split design makes it easier for users to install. When the user slides the bearing seat 630 into the slide seat 8, the positioning member 9 cooperates with the positioning portion 80 to fix the bearing seat 630 in the slide seat 8 to achieve positioning, and the structure is simple and easy to use.
[0037] like Figures 1 to 6As shown in the figure, the positioning member 9 is a positioning bolt 90, the positioning portion 80 is a positioning blind hole 800. A positioning post 660 penetrating through the bearing seat 630 is provided in the accommodation cavity 640. The positioning blind hole 800 is provided at a position on the chute seat 8 that matches the positioning post 660. A second threaded through hole 670 is provided in the positioning post 660. The positioning bolt 90 passes through the shaft hole 610 of the steering shaft 600 and cooperates with the second threaded through hole 670 of the positioning post 660 to be locked and fixed in the positioning post 660. The screw rod of the positioning bolt 90 is embedded in the positioning blind hole 800.
[0038] In this embodiment, the positioning member 9 is a positioning bolt 90, as Figure 2 shown. A knob can be provided at the head of the positioning bolt 90 to facilitate the operation by the user. The screw rod of the positioning bolt 90 is embedded in the positioning blind hole 800, which can realize the positioning of the bearing seat 630 in the chute seat 8, making the wheel more stable during steering. At the same time, the cooperation between the positioning bolt 90 and the positioning blind hole 800 makes the loading and unloading process more convenient. When maintenance or component replacement is required, only by unscrewing the positioning bolt 90 can the disassembly be completed, reducing the maintenance difficulty and cost. In addition, the positioning post 660 and the positioning blind hole 800 utilize the internal space of the steering shaft 600 and the accommodation cavity 640, making the whole structure more compact. Of course, in other embodiments, the sizes of the positioning post 660 and the positioning blind hole 800 can be adjusted according to the actual situation to adapt to different sizes and types of bearings 620.
[0039] Furthermore, when the wheel steering structure of this embodiment is installed in front of an external object, a connecting seat 200 for installing a pull rod 300 is provided at the other end of the driving member 6 in this embodiment, which is more convenient for the user to control the other end of the driving member 6 by using the pull rod 300, and the design is user-friendly. When the wheel steering structure of this embodiment is installed behind an external object, the driving member 6 and the bearing 620 do not need to be provided.
[0040] Taking the camping cart 100 as an example, as Figure 7 and Figure 8 shown, the using process of the present utility model is as follows:
[0041] The user first fixedly installs the chute seat 8 at the installation position at the bottom of the camping cart 100, selects an installation frame 7 with a suitable height and fixes the installation frame 7 in the middle section of the bottom tube 1, and fixes one end of the driving member 6 on the installation frame 7, above the middle section of the bottom tube 1.
[0042] Select a bearing 620 with a suitable size and fixedly sleeved on the steering shaft 600. Cover the bearing seat 630 on the bearing 620 through the accommodating cavity 640. Use a set screw to pass through the first threaded through hole 650 and abut against the outer ring of the bearing 620 to fix the bearing 620 on the bearing seat 630. Then slide the entire wheel steering structure into the chute seat 8 through the bearing seat 630. Use the positioning bolt 90 to pass through the shaft hole 610 of the steering shaft 600 and cooperate with the second threaded through hole 670 of the positioning column 660 for locking and fixing until the screw rod of the positioning bolt 90 is embedded in the positioning blind hole 800. Thus, the installation is completed.
[0043] When steering is required, the user bends the pull rod 300 at the other end of the driving member 6 to the left or right, so that one end of the driving member 6 rotates relative to the camping cart 100 through the bearing 620. Since the rotation of the mounting seat 4 around the axis of the rotating shaft 3 is restricted by the cooperation of the limiting block 41 and the limiting groove 21 between the connecting member 2 and the mounting seat 4, the two wheels rotate synchronously. And the limiting block 41 of the mounting seat 4 slides longitudinally in the limiting groove 21 of the connecting member 2, and cooperates with the elastic member 5 on the sliding path of the mounting seat 4, so as to effectively damp the two wheels during driving.
[0044] The orientation terms mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts, so they may change accordingly according to their different positions and different usage states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.
[0045] The above are only the preferred embodiments of the present invention, and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
