Description

Technical Field

[0001] The invention belongs to the technical field of commodity display stands, and particularly relates to a motorcycle display stand. Background Art

[0002] When motorcycle manufacturers participate in exhibitions, they usually use special display racks to support the front and rear wheels of the motorcycles to make them more stable when standing upright. The common structures of motorcycle display racks include the following types:

[0003] One type features a wide rectangular base, typically welded together from various pipes to form a frame. The motorcycle is then pushed into the center of the frame, with the tires secured using various snap-on mechanisms. To prevent the motorcycle from tipping over, multiple steel cables are used to secure the wheels or frame to the base. However, this structure is rudimentary, significantly diminishing the brand's reputation. Furthermore, positioning the motorcycle is labor-intensive and time-consuming, and the cables present a safety risk of loosening.

[0004] Another type of structure is to make a groove structure that matches the size of the tire. When placing a motorcycle, it is necessary to lift the motorcycle, let the wheels off the ground at a certain height, and then insert the motorcycle wheels into the groove. This is time-consuming and labor-intensive. In addition, the shapes and sizes of motorcycle wheels of different models are different. A corresponding groove structure needs to be prepared separately for each model. Otherwise, there is a safety risk of the motorcycle shaking, falling out of the groove, or even tipping over.

[0005] Another type of structure is the triangular fork structure (also called a front wheel mount). Its main structure is a triangular fork support structure in the X, Y, and Z directions. There is a tilting gear slot between the X and Y directions, and a vertical gear slot in the Z direction. The motorcycle wheels snap into the two gear slots to park. However, the disadvantages of this structure are that the entire structure takes up a lot of space. Secondly, the tilting gear slot is easy to rotate, which may cause the motorcycle to fall off the display stand. It is not suitable for exhibitions where many non-professionals touch and test drive the vehicles, otherwise it will pose a safety hazard.

[0006] Therefore, a special motorcycle display rack with small space occupation, strong applicability and high safety is needed. Summary of the Invention

[0007] The present invention aims to provide a motorcycle display stand which occupies a small space, has strong applicability and high safety.

[0008] In order to achieve the above-mentioned purpose, the scheme of the present invention is as follows: a motorcycle display stand includes a platform frame, a driving mechanism, two pairs of self-tightening mechanisms and two flip clamps, a groove is provided on the top surface of the platform frame, the two pairs of self-tightening mechanisms and the two flip clamps are respectively located on both sides of the groove, a pad is provided in the groove, and an elastic member is provided between the bottom surface of the pad and the groove; the driving mechanism includes a pressure plate, an active structure and a passive structure, one end of the pressure plate is hinged to the platform frame, and the other end of the pressure plate is a free end, the active structure is connected to the bottom surface of the pressure plate or the active structure is pressed against the bottom surface of the pressure plate, and the passive structure is rotatably connected to the platform The active structure is connected to the passive structure on the frame, and the active structure can drive the passive structure to rotate along the connection point between the passive structure and the platform frame; the self-tightening mechanism includes a rotating arm and a self-tightening arm, one end of the self-tightening arm is hinged to the end face of the pad, and the other end of the self-tightening arm is hinged to the bottom face of the flip clamp, one end of the rotating arm is statically connected to the passive structure, and the other end of the rotating arm is hinged to the bottom face of the flip clamp, the rotating arm is hinged by a first-section arm and a second-section arm, and the second-section arm can rotate toward the self-tightening arm side relative to the first-section arm, and the hinges at both ends of the self-tightening arm and the rotating arm and the flip clamp are hinged through universal joints.

[0009] The working principle and beneficial effects of this solution are:

[0010] 1. Because the self-tightening mechanism and the flip clamp are hingedly connected to the platform frame, they can collapse onto the platform frame when no force is applied, significantly saving space. When a motorcycle is placed on the display stand, the entire structure only occupies a small amount of space below the motorcycle and under the wheels. Compared to existing technologies, this significantly reduces space usage.

[0011] 2. When placing a motorcycle, push the motorcycle forward, allowing its wheels to roll over the pressure plate. The pressure plate rotates under pressure, driving the active structure to drive the passive structure to rotate, thereby driving the rotating arm and the self-tightening arm to stand up, and then driving the entire flip clamp to stand up on both sides of the wheel. As the wheel continues to press forward onto the pad, the pad is pressed and sinks, driving the self-tightening arm downward. During the downward movement, the self-tightening arm clamps inward, allowing the flip clamp to clamp the wheel from both sides, and the wheel can be placed. Regardless of the vehicle model or the diameter and width of the wheel, clamping can be achieved, and the applicability is excellent.

[0012] 3. Once the motorcycle is positioned, its own gravity keeps the flip clamp securely clamped to the wheel. There's no risk of the motorcycle rolling back, and there's no worry about the clamp loosening. This provides superior safety compared to any existing structure. Once the motorcycle is unloaded, the self-tightening mechanism and flip clamp reset under their own gravity, eliminating the need for additional space. Optimizing the structural design allows the platform to be designed as a low-profile tabletop (with only the pressure plate protruding above the surface). The overall structure is simple and elegant, ensuring it doesn't diminish the quality of the participating motorcycle brands.

[0013] Optionally, the active structure is a push rod, the passive structure is a lever, the middle part of the lever is rotatably connected to the platform frame, one end of the push rod is hinged to the pressure plate, the other end of the push rod is hinged to one end of the lever, and the rotating arm is statically connected to the end of the lever away from the push rod.

[0014] Optionally, the active structure is a rack, and the passive structure includes a rotating shaft and a gear. The rotating shaft is rotatably connected to the platform frame, the gear is coaxially fixedly connected to the rotating shaft, the gear is engaged with the rack, and the rotating arm is fixedly connected to the gear or the rotating shaft.

[0015] Optionally, an elastic reset member is connected to one end of the rack away from the pressure plate.

[0016] Optionally, the platform frame is provided with an accommodating groove for accommodating the driving mechanism, the self-tightening mechanism and the flip clamp.

[0017] Optionally, the flip clamp is Y-shaped.

[0018] Optionally, a buffer pad is provided on the end of the flip clamp facing the groove.

[0019] Optionally, the two opposite side walls of the groove are inclined walls, and the slope of the inclined walls gradually increases from the groove mouth to the groove bottom of the groove, and a tightening strip is provided on the inclined walls.

[0020] Optionally, a guide column is provided on the bottom surface of the pad, and a guide blind hole for inserting the guide column is opened on the bottom wall of the groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is further described in detail through specific implementation methods:

[0027] The marks in the drawings of the specification include: platform frame 1, groove 101, accommodating groove 102, flip clamp 2, tightening strip 3, pad 4, elastic member 5, guide column 6, guide blind hole 7, pressure plate 8, push rod 9, lever 10, rotating arm 11, first section arm 111, second section arm 112, self-tightening arm 12, universal joint 13, wheel 14, rack 15, rotating shaft 16, gear 17, elastic reset member 18.

[0028] Example 1

[0029] This embodiment is basically as Figure 1 、 Figure 2 and Figure 3 As shown: The motorcycle display stand includes a platform frame 1, a driving mechanism, two self-tightening mechanisms and two flip clamps 2. A groove 101 is provided on the top surface of the platform frame 1. The two self-tightening mechanisms and the two flip clamps 2 are respectively located on both sides of the groove 101. The flip clamps 2 can stand up and clamp the wheel 14 under the action of the driving mechanism and the self-tightening mechanism. The two opposite walls of the groove 101 are inclined walls, and the slope of the inclined walls gradually increases from the notch of the groove 101 to the bottom of the groove 101. Figure 4 As shown, a tightening strip 3 is integrally formed on the inclined wall to facilitate the self-tightening mechanism to work better. A pad 4 is provided in the groove 101, and a plurality of elastic members 5 are provided between the bottom surface of the pad 4 and the bottom of the groove 101. In this embodiment, there are four elastic members 5, and the elastic members 5 are pressure springs. The top end of the pressure spring is fixedly connected to the pad 4, and the bottom end of the pressure spring is fixedly connected to the bottom of the groove 101. In addition, a guide column 6 is integrally formed on the bottom surface of the pad 4, and a guide blind hole 7 for inserting the guide column 6 is provided on the bottom wall of the groove 101. In this way, the guide column 6 slides vertically in the guide blind hole 7 to ensure the vertical movement of the pad 4 and prevent the pad 4 from shaking horizontally.

[0030] The platform frame 1 is provided with a receiving slot 102 for accommodating the drive mechanism, the self-tightening mechanism, and the flip clamp 2. The drive mechanism includes a pressure plate 8, an active structure, and a passive structure. One end of the pressure plate 8 is hinged to the platform frame 1, and the other end of the pressure plate 8 is free and tilted. The active structure is connected to the bottom surface of the pressure plate 8, and the passive structure is rotatably connected to the side wall of the receiving slot 102. The active structure is connected to the passive structure and can drive the passive structure to rotate along the rotation connection point between the passive structure and the receiving slot 102. The self-tightening mechanism includes a rotating arm 11 and a self-tightening arm 12. One end of the self-tightening arm 12 is hinged to the end surface of the pad 4 through a universal joint 13, and the other end of the self-tightening arm 12 is hinged to the bottom surface of the flip clamp 2 through a universal joint 13. The self-tightening arm 12 is in contact with the end of the tightening strip 3 away from the inclined wall of the groove 101; one end of the rotating arm 11 is statically connected to the passive structure, and the other end of the rotating arm 11 is hinged to the bottom surface of the flip clamp 2 through a universal joint 13. The rotating arm 11 consists of a section of the arm 11 The first and second arms 111 are hingedly connected, and the second arm 112 can rotate relative to the first arm 111 toward the self-tightening arm 12 side. Specifically, the end of the first arm 111 away from the second arm 112 is connected to the passive structure by bolts, and the first arm 111 and the second arm 112 are hingedly connected by a pin shaft and a pin hole. In this way, the second arm 112 can only rotate relative to the first arm 111 along the axial direction of the pin shaft, thereby realizing the rotation of the second arm 112 relative to the first arm 111 toward the self-tightening arm 12 side.

[0031] In addition, in this embodiment, the active structure is the push rod 9, and the passive structure is the lever 10. The middle part of the lever 10 is rotatably connected to the side wall of the accommodating groove 102, the top end of the push rod 9 is hinged to the pressure plate 8, and the bottom end of the push rod 9 is hinged to one end of the lever 10. The other end of the lever 10 is connected to the end of the first arm 111 away from the second arm 112 through a bolt.

[0032] The flip clamp 2 is Y-shaped, so that when the flip clamp 2 is clamped on the wheel 14, there are two contact points between the flip clamp 2 and the wheel 14, thereby better supporting and fixing the wheel 14 and improving the motorcycle fixing effect. A buffer pad is provided on the end of the flip clamp 2 facing the groove 101 to protect the wheel 14.

[0033] Before the motorcycle is put on the platform frame 1, or before the motorcycle rolls over the pressure plate 8, the self-tightening mechanism and the flip clamp 2 are not subjected to force, the rotating arm 11 and the flip clamp 2 fall down in the receiving groove 102, and the self-tightening arm 12 falls down on the platform frame 1, taking up little space (since the flip clamp 2 in this embodiment is Y-shaped, part of it is exposed outside the receiving groove 102. When the flip clamp 2 is strip-shaped, the part of the flip clamp 2 exposed outside the receiving groove 102 is very small, and it takes up even less space). When the motorcycle needs to be placed, the motorcycle is put on the platform frame 1, and the wheel 14 rolls over the pressure plate 8. The pressure plate 8 is forced to rotate, driving the push rod 9 to drive the lever 10 to rotate with the rotation connection point between the lever 10 and the side wall of the receiving groove 102 as the center of the circle, thereby driving the rotating arm 11 and the self-tightening arm 12 to stand up, and then driving the flip clamp 2 to stand up on both sides of the wheel 14. At the same time, the self-tightening arm 12 fits the tightening strip 3 on the inclined wall of the groove 101, as shown in FIG. Figure 3 and Figure 4 As shown. When the wheel 14 continues to press forward onto the pad 4, the pad 4 is pressed and sinks, driving the self-tightening arm 12 to move downward. During the downward movement, the self-tightening arm 12 slides against the tightening bar 3 and drives the flip clamp 2 to clamp inward ("inside" means the side facing the wheel 14), so that the flip clamp 2 clamps the wheel 14 from both sides of the wheel 14, and the wheel 14 can be placed. During the process of the flip clamp 2 clamping the wheel 14, the second-section arm 112 rotates toward the self-tightening arm 12 relative to the first-section arm 111. Regardless of how the vehicle model changes or how the diameter and width of the wheel 14 change, this embodiment can achieve the clamping of the wheel 14 and has good applicability. After the wheel 14 is clamped, the gravity of the wheel 14 will keep the flip clamp 2 clamped on the wheel 14. There is no risk of the motorcycle rolling back, and there is no need to worry about the clamping force becoming loose, which is highly safe.

[0034] After the motorcycle exits the groove 101 under the action of external force, the pad 4 moves upward and resets under the action of the elastic member 5, driving the self-tightening arm 12 to move upward, thereby driving the flip clamp 2 to move outward, and at the same time, the second-section arm 112 rotates relative to the first-section arm 111 to the side away from the self-tightening arm 12; at the same time, the self-tightening mechanism and the flip clamp 2 can be reset under the action of their own gravity, that is, the rotating arm 11 and the flip clamp 2 fall down in the accommodating groove 102, and the self-tightening arm 12 falls down on the platform frame 1.

[0035] In summary, in this embodiment, the motorcycle can be placed quickly, and the weight of the motorcycle wheel 14 is used to clamp the wheel 14. There is no need to worry about the clamping force becoming loose, the safety is good, and it is suitable for various wheel 14 sizes and has a wide range of applications.

[0036] Example 2

[0037] The difference between this embodiment and the first embodiment is that: Figure 5As shown, the active and passive structures in this embodiment are different from those in the first embodiment. In this embodiment, the active structure is a rack 15, and the passive structure includes a rotating shaft 16 and a gear 17. The rotating shaft 16 is rotatably connected to the side wall of the receiving groove 102, and the gear 17 is coaxially fixedly connected to the rotating shaft 16. The gear 17 meshes with the rack 15. The rotating arm 11 is fixedly connected to the gear 17 or the rotating shaft 16. In this embodiment, the end of the first section arm 111 away from the second section arm 112 is welded to the rotating shaft 16. An elastic reset member 18 is welded to the bottom end of the rack 15, and the top end of the rack 15 abuts against the pressure plate 8. In this embodiment, the elastic reset member 18 is a telescopic spring. In addition, the rack 15 slides along the inclined wall of the receiving groove 102.

[0038] In this embodiment, when the wheel 14 rolls over the pressure plate 8, the pressure plate 8 is forced to rotate, driving the rack 15 downward and compressing the elastic return member 18. Since the rack 15 is meshed with the gear 17, the gear 17 rotates clockwise, thereby driving the rotating shaft 16 to rotate clockwise, thereby driving the rotating arm 11 and the self-tightening arm 12 to stand up, and at the same time, causing the flip clamp 2 to stand up on both sides of the wheel 14. Subsequently, after the wheel 14 continues to press forward onto the pad 4, the pad 4 is pressed downward, driving the self-tightening arm 12 to move downward along the inclined wall of the groove 101. During the downward movement, the self-tightening arm 12 drives the flip clamp 2 to clamp inward, so that the flip clamp 2 clamps the wheel 14 from both sides, and the wheel 14 is placed.

[0039] After the motorcycle exits the groove 101 under the action of external force, the pad 4 moves upward and resets under the action of the elastic member 5, driving the self-tightening arm 12 to move upward, thereby driving the flip clamp 2 to move outward, and at the same time, the second-section arm 112 rotates relative to the first-section arm 111 to the side away from the self-tightening arm 12; at the same time, the self-tightening mechanism and the flip clamp 2 can be reset under the action of their own gravity and the elastic reset member 18, that is, the rack 15 moves upward and resets under the push of the elastic reset member 18, and pushes the free end of the pressure plate 8 to tilt up again, and the gear 17 rotates counterclockwise, thereby driving the rotating arm 11 to rotate counterclockwise, and the rotating arm 11 and the flip clamp 2 fall into the accommodating groove 102, and the self-tightening arm 12 falls on the platform frame 1.
