Description

Technical Field

[0001] The present invention relates to the technical field of scooters, and in particular to a shock-absorbing scooter. Background Art

[0002] The scooter is a common sports product. Compared with a bicycle, it is simpler and more portable, and easier to use than a skateboard. Because it is both instrumental and entertaining, the scooter has gradually become a widely accepted means of transportation.

[0003] For example, a Chinese utility model patent with authorization announcement number CN2453988Y and authorization announcement date October 17, 2001 discloses a shock absorbing device for a scooter, and specifically discloses that a beam is provided below the pedal and is integral with the beam, the front upper end of the rear wheel support frame is hinged with the rear upper end of the beam through an axis, the front lower end of the rear wheel support frame is hinged with the thick end of a trapezoidal connecting rod, the thin end of the connecting rod passes through a through hole on a positioning card fixed at the bottom end of the beam, and a spring is sleeved on it, one end of the spring is against the positioning card, and the other end is fixed by a nut set at the thin end of the connecting rod. When the scooter encounters vibration during travel, the rear wheel support frame rotates with the axis as the axis, and when the rear wheel moves up, the lower end of the rear wheel support frame pulls the connecting rod to move backward, the spring is compressed, and after the vibration is eliminated, the elastic force of the spring moves the connecting rod forward to reset the rear wheel, and the rear wheel can play a shock absorbing role by moving up and down in this way.

[0004] The scooter in the prior art adopts an integrated beam and pedal structure, the rear wheel support frame is rotatably mounted on the rear of the beam, and a connecting rod and a spring are connected between the rear wheel support frame and the bottom end of the beam, and the vibration transmitted from the rear wheel to the pedal is reduced by the compression deformation of the spring. However, the spring arranged at the rear wheel can only buffer the vibration of the rear wheel, and cannot eliminate the impact of the vibration of the front wheel on the pedal. Moreover, if corresponding shock-absorbing structures are arranged at the front wheel and the rear wheel respectively, the structure of the whole vehicle will be complicated, which is not conducive to controlling production costs.

[0005] In summary, the scooter in the prior art has the problem of not being able to achieve both shock absorption effect and simple structure. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a shock-absorbing scooter to solve the problem that the existing scooters cannot achieve both shock-absorbing effect and simple structure.

[0007] The technical solution of the shock absorbing scooter of the present invention is:

[0008] The shock-absorbing scooter comprises a frame, a pedal, a front wheel and a rear wheel. The frame comprises a front frame and a rear beam body rotatably connected to the front frame. The front wheel is rotatably mounted on the lower part of the front frame, and the rear wheel is rotatably mounted on the rear part of the rear beam body. The pedal is arranged on the upper side of the rear beam body and is hinged to the wheel axle of the rear wheel. An elastic member is arranged between the pedal and the rear beam body to buffer the vibration transmitted from the frame to the pedal.

[0009] Beneficial effects: When the wheels encounter bumps on the road during driving, the rear beam vibrates up and down with the front and rear wheels. Since an elastic member is provided between the rear beam and the pedal, the elastic member is effectively buffered and shock-absorbed when the vibration is transmitted to the elastic member, ensuring the stable support of the pedal for the rider, reducing the transmission of vibration energy to the human body, and improving the stability of driving. Compared with setting a shock-absorbing structure at the front and rear wheels, it avoids making the structure of the whole vehicle complicated, and takes into account both the shock-absorbing effect and the simple structure.

[0010] Furthermore, in order to improve the structural strength of the rear beam, a corresponding connecting portion is constructed for the elastic member, the rear beam includes two longitudinal beams arranged at intervals and reinforcing transverse ribs connecting the two longitudinal beams, and the elastic member is a compression spring connected between the reinforcing transverse ribs and the pedal.

[0011] Furthermore, in order to construct sufficient installation space at the front wheel, improve the traffic capacity of the scooter, and ensure a lower pedal height, the longitudinal beam is a curved longitudinal beam, the curved longitudinal beam includes an integrated horizontal section and an inclined section extending obliquely upward, and a rotating sleeve is fixed on the inclined sections of the two curved longitudinal beams, and the rotating sleeve is arranged on the handlebar main rod of the front frame.

[0012] Furthermore, in order to improve the safety when riding the scooter, the pedal is a curved pedal adapted to the shape contour of the rear beam, and the curved pedal includes an integrated load-bearing section and a buffer section, the load-bearing section corresponds to the horizontal section of the curved longitudinal beam, and the buffer section corresponds to the inclined section of the curved longitudinal beam and extends obliquely upward.

[0013] Furthermore, the pedal is made of a composite wood board, which is lightweight and shock-absorbing, creating a more realistic skateboarding experience for the rider.

[0014] Furthermore, in order to provide good elastic support for the buffer section, at least two reinforcing transverse ribs are provided, one of which is a buffer transverse rib that connects the inclined sections of the two curved longitudinal beams, and a compression spring is connected between the buffer transverse rib and the opposite surface of the buffer section of the pedal.

[0015] Furthermore, in order to ensure the balance of the pedal when it is pressed down and avoid the pedal from tilting due to the unstable support of a single cylindrical compression spring, two compression springs are arranged in parallel along the length direction of the reinforcing transverse rib.

[0016] Furthermore, in order to facilitate the hinged connection between the pedal and the rear beam, an angle support is provided at the rear end of the pedal, and the angle support includes a fitting portion for connecting to the board surface of the pedal and a supporting portion perpendicular to the fitting portion, and the supporting portion is provided with a snap-on for rotating and assembling the wheel axle of the rear wheel.

DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] A specific embodiment 1 of the shock-absorbing scooter of the present invention is as follows Figures 1 to 4As shown, the shock-absorbing scooter includes a frame, a pedal, a front wheel 4 and a rear wheel 5. The frame includes a front frame 1 and a rear beam body 2. The front frame 1 includes a handlebar main rod 10 and a handle 11 arranged at the upper end of the handlebar main rod 10. The lower end of the handlebar main rod 10 is provided with a front wheel frame, and the front wheel 4 is rotatably mounted on the front wheel frame. The rear beam body 2 includes two longitudinal beams and reinforcing transverse ribs 21 connecting the two longitudinal beams. The two longitudinal beams have the same structure and are symmetrically arranged about the longitudinal center axis of the scooter. The rear wheel 5 is rotatably mounted on the rear part of the rear beam body 2. Both longitudinal beams are curved longitudinal beams 20. A rotating sleeve 202 is connected to the front end of the two curved longitudinal beams 20. The rotating sleeve 202 is sleeved on the handlebar main rod 10 and rotatably cooperates with the handlebar main rod 10. The rider holds the handle 11 and rotates the handlebar main rod 10 according to the actual road conditions to adjust the direction of the front wheel 4 to change the driving direction of the scooter.

[0027] The curved longitudinal beam 20 includes an integrated horizontal section 200 and an inclined section 201 extending obliquely upward. The rotating sleeve 202 is connected to the front end of the inclined section 201 of the two curved longitudinal beams 20. The horizontal section 200 and the inclined section 201 are connected in a smooth transition. The inclined section 201 ensures that a larger front wheel 4 can be installed, and sufficient installation space is constructed for the front wheel 4, which improves the traffic capacity of the scooter and ensures a lower height of the pedal 3. The rear end of the horizontal section 200 of the curved longitudinal beam 20 is fixed to the axle 50 of the rear wheel 5. A rolling bearing is provided between the rear wheel 5 and the axle 50 to achieve a rotational connection between the two. A transversely extending reinforcing transverse rib 21 is connected between the two curved longitudinal beams 20. There are three reinforcing transverse ribs 21, two of which are connected between the horizontal sections 200 and arranged in parallel and spaced apart. One of the reinforcing transverse ribs 21 is a buffer transverse rib connected between the inclined sections 201, and the buffer transverse rib is higher than the position of the other two reinforcing transverse ribs 21.

[0028] The pedal is a curved pedal 3, which is adapted to the shape and contour of the rear beam 2. The curved pedal 3 includes an integrated load-bearing section 30 and a buffer section 31. The load-bearing section 30 corresponds to the horizontal section 200 of the curved longitudinal beam 20, and the buffer section 31 corresponds to the inclined section 201 of the curved longitudinal beam 20 and extends obliquely upward. The load-bearing section 30 and the buffer section 31 of the curved pedal 3 are smoothly transitioned and connected. A cylindrical compression spring 6 is provided between the curved pedal 3 and the reinforcing transverse rib 21, and the two ends of the cylindrical compression spring 6 are respectively connected between the lower plate surface of the curved pedal 3 and the upper side surface of the reinforcing transverse rib 21. Figure 5As shown, each reinforcing transverse rib 21 is provided with a pair of cylindrical compression springs 6, and the two cylindrical compression springs 6 on each reinforcing transverse rib 21 are arranged at intervals in the transverse direction, and the cylindrical compression springs 6 form an elastic member for buffering the vibration transmitted from the frame to the curved pedal 3. The paired cylindrical compression springs 6 play an elastic supporting role on the curved pedal 3, and the paired cylindrical compression springs 6 can ensure the balance of the curved pedal 3 during the downward pressing action, and avoid the curved pedal 3 from tilting due to the unstable support of a single cylindrical compression spring 6.

[0029] Among them, a pair of cylindrical compression springs 6 provided on the buffer transverse ribs are arranged along the extension direction perpendicular to the inclined section 201. When the buffer section 31 of the curved pedal 3 is subjected to deformation pressure perpendicular to the board surface direction of the buffer section 31, the cylindrical compression spring 6 can be compressed and deformed normally, thereby playing a good elastic support role for the buffer section 31, avoiding the cylindrical compression spring 6 from bending and deforming due to the compression direction being inconsistent with its length extension direction. The curved pedal 3 is made of composite wood board. Since it is made of multiple layers of wood boards, the curved pedal 3 has the characteristics of strong elastic deformation ability and high structural strength. Moreover, compared with metal materials and resin materials, the composite wood board also takes into account lightweight and shock absorption, creating a more realistic skateboarding experience for the rider.

[0030] The bearing section 30 of the curved pedal 3 extends backward to have a left wing part and a right wing part. A mounting notch for accommodating the rear wheel 5 is reserved between the left wing part and the right wing part. A wheel cover 51 is provided at the position of the bearing section 30 corresponding to the mounting notch. The wheel cover 51 covers the outer periphery of the rear wheel 5 to prevent the rear wheel 5 from splashing muddy water on the rider during driving. An angle support 32 is provided at the rear of the left wing part of the bearing section 30, such as Figure 6 , Figure 7 As shown, the angle support 32 includes a fitting portion 320 and a supporting portion 321 which are perpendicular to each other. The fitting portion 320 is provided with a bolt hole for the bolt to pass through. The bolt is screwed into the bolt hole to fit the angle support 32 to the lower plate surface of the bearing section 30. The supporting portion 321 is in a vertical plane and is provided with a bayonet 322 at a lower position, and is hingedly connected to the axle 50 of the rear wheel 5 through the bayonet 322. The curved pedal 3 is only subject to axial constraints along the axis of the wheel axle 51 and elastic support perpendicular to the board surface. When the rider steps on the load-bearing section 30, the curved pedal 3 rotates around the axis of the wheel axle 51 and presses down the cylindrical compression spring 6. The compression deformation of the cylindrical compression spring 6 plays an elastic supporting role for the curved pedal 3. When the wheels encounter a bump on the road during driving, the rear beam 2 vibrates up and down with the front wheel 4 and the rear wheel 5. Since the cylindrical compression spring 6 is provided between the rear beam 2 and the curved pedal 3, when the vibration is transmitted to the cylindrical compression spring 6, it is effectively buffered and shock-absorbed by the cylindrical compression spring 6, thereby ensuring the stable support of the curved pedal 3 for the rider, reducing the transmission of vibration energy to the human body, and improving the driving stability.

[0031] Specific embodiment 2 of the shock-absorbing scooter of the present invention is different from specific embodiment 1 in that, in order to simplify the structure, the two curved longitudinal beams can be replaced by a main longitudinal beam arranged along the longitudinal center axis of the scooter, and a spring support plate is welded on the main longitudinal beam, and the spring support plate has a support plate surface for fixing and connecting the lower end of the cylindrical compression spring. In other embodiments, two spring support plates can be respectively arranged on the left and right sides of the main longitudinal beam, and cylindrical compression springs are respectively arranged on the left and right spring support plates, so that the curved pedal is stably supported by the cylindrical compression spring to ensure the balance of the curved pedal when it is compressed and deformed.

[0032] Specific embodiment 3 of the shock-absorbing scooter of the present invention is different from specific embodiment 1 in that, in order to improve the supporting strength of the curved pedal, the cylindrical compression spring can be replaced by a leaf spring, the middle raised position of the leaf spring is connected to the reinforcing transverse rib, and the two ends of the leaf spring are connected to the lower plate surface of the curved pedal, so that the leaf spring provides high-strength elastic support for the curved pedal.

[0033] Specific embodiment 4 of the shock-absorbing scooter of the present invention is different from specific embodiment 1 in that, in order to simplify the structure, the curved pedal and the angle support can be designed as an integrated structure, the curved pedal is made of a metal plate, and a bending section is set at the left and right wing parts of the rear end of the curved pedal. The bending section is in a vertical plane and the lower part is provided with a bayonet for the articulated wheel axle. The bending section is equivalent to the supporting part of the angle support in specific embodiment 1, eliminating the parts of the angle support and simplifying the subsequent assembly process. In other embodiments, a twisting section can be set at the left and right wing parts of the rear end of the curved pedal. The twisting section is in a vertical plane and the lower part is provided with a bayonet for the articulated wheel axle.
