Description

Technical Field

[0001] The utility model relates to a reverse tricycle, in particular to a tilt locking mechanism for a reverse tricycle Background Art

[0002] Existing inverted tricycles utilize a suspension mechanism to connect the wheels to the frame, transferring forces and torque between the wheels and the frame, and cushioning impact forces transmitted to the frame or body from uneven roads. The suspension mechanism typically includes a main frame, a buffer mechanism, a steering mechanism, a locking mechanism, and a rocking mechanism mounted on the main frame. The locking mechanism on the main frame cooperates with the rocking mechanism to enable relative rotation or fixation between the rocking mechanism and the main frame, enabling the inverted tricycle to adapt to various road conditions and achieve optimal riding conditions.

[0003] Patent publication number CN217575487U discloses a swing locking mechanism and a reverse tricycle. The swing locking mechanism comprises a first housing and a second housing connected to each other. The first housing houses a transmission assembly and a drive assembly connected to the transmission assembly. The second housing houses a clamping assembly, with an abutment disposed between the clamping assembly and the transmission assembly. The transmission assembly drives the abutment toward the clamping assembly, causing the clamping assembly to lock the locking plate. This simplifies the design and improves reliability during use.

[0004] Although the above locking mechanism can lock the swing mechanism, the clamping assembly uses four slides to lock the two locking plates, which is complex in structure, increases the cost and the size of the device. Summary of the Invention

[0005] Purpose of the utility model: The purpose of the utility model is to provide a tilt locking mechanism for a reverse three-wheeled motorcycle with a simple structure.

[0006] Technical solution: The utility model discloses a tilt locking mechanism for an inverted three-wheeled motorcycle, comprising a slide, two locking plates and a clamping device for driving the slides toward each other. A slide is provided on the outside of each of the two locking plates, and the opposing surfaces of the two locking plates are concave and convex.

[0007] Based on the above technical solution, by setting the opposing surfaces of the two locking plates into a concave-convex shape, it is possible to avoid the two locking plates from sliding relative to each other to achieve locking when the two slides clamp the locking plates. In this way, only one slide is required on the outside of each locking plate without setting a slide on both sides of each locking plate to clamp the locking plate. That is, two slides are saved between the two locking plates, the structure is simpler, the cost is saved and the size of the device is reduced.

[0008] Preferably, the opposing surfaces of the two locking plates are provided with knurling.

[0009] Knurling is a conventional process and is relatively easy to manufacture.

[0010] Preferably, the clamping device is provided with at least two guide rods, and the slide is slidably connected to the guide rods.

[0011] Providing at least two guide rods can prevent the slide from rotating relative to the guide rod compared to providing one guide rod.

[0012] Preferably, the guide rod is provided with a limiting mechanism for preventing the slide from falling off.

[0013] The limiting mechanism can prevent the slide from slipping off the guide rod during use.

[0014] Preferably, the length of the guide rod is greater than the sum of the thicknesses of all the sliding plates and the locking plates.

[0015] The length of the guide rod is set in this way so that when the two slides are separated to the farthest, the two locking plates can be separated from each other, thereby avoiding mutual wear during the swinging process and reducing losses.

[0016] Preferably, a spring is provided between the two slides for separating the two slides.

[0017] A spring is provided to automatically separate the two slides when the clamping device is not clamped.

[0018] Preferably, the upper and lower widths of the sliding plate are greater than the upper and lower widths of the locking plate.

[0019] The upper and lower widths of the sliding plate are greater than the upper and lower widths of the locking plate, so that the sliding plate can clamp the locking plate more securely.

[0020] Preferably, the opposing surfaces of the sliding plate and the locking plate are concave-convex.

[0021] The opposing surfaces of the sliding plate and the locking plate are also arranged in a concave-convex shape to prevent the sliding plate and the locking plate from sliding relative to each other during clamping.

[0022] Preferably, the locking piece is arc-shaped.

[0023] The arc shape of the locking plate can prevent the end of the locking plate from moving too much upward or downward when the wheel swings, which requires reserving too much moving space for it and increases the size of the entire vehicle.

[0024] Preferably, the sliding plate is arc-shaped to match the locking plate.

[0025] When the shapes of the sliding plate and the locking plate match so that the two can maintain a good fit, the volume of the sliding plate is smaller. For example, if the sliding plate is set to be rectangular, in order to maintain fit with the opposite surface of the locking plate, its upper and lower widths must be set larger than the arc, which increases the volume and cost.

[0026] Beneficial effect: Compared with the prior art, the beneficial effect of the present invention is that by setting the opposing surfaces of the two locking plates into a concave-convex shape to prevent the two from sliding relative to each other during clamping, only one sliding plate is required on the outer side of each of them, thus saving two sliding plates, making the structure simpler, and reducing the cost and device volume. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 This is a schematic diagram of the structure of this organization;

[0028] Figure 2 This is a structural diagram of the mechanism excluding the locking plate. DETAILED DESCRIPTION

[0029] As shown in the figure, since the clamping device is an existing device, the figure only shows a partial structure of the clamping device, mainly showing the sliding plate 1 and the locking plate 2.

[0030] The tilt locking mechanism for an inverted three-wheeled motorcycle described in the utility model comprises a slide 1, two locking plates 2 and a clamping device for driving the slides 1 to approach each other. A slide 1 is provided on the outside of each of the two locking plates 2, and the opposing surfaces of the two locking plates 2 are concave and convex.

[0031] The clamping device can adopt the structure of the transmission assembly and drive assembly in CN217575487U for clamping the two slides 1, or it can adopt the hydraulic oil transmission structure commonly used in the brake mechanism of existing motorcycles or electric vehicles. Its structure will not be described in detail herein; no matter what mechanism the clamping device adopts, there is a relatively fixed support mechanism, which is provided with at least two guide rods 3, and the slide 1 is slidably connected to the guide rods 3. A total of two slides 1 are used, and a spring 4 is provided between the two slides 1 to separate the two. In this way, the slide 1 can be reset when the clamping device is not clamped, and then the two locking plates 2 can be separated to avoid loss caused by mutual contact friction; a limiting mechanism can also be provided at the end of the guide rod 3 to prevent the slide 1 from slipping off. The limiting mechanism can be a radially protruding flange, or an annular groove can be provided at the end, and an annular baffle is clamped in the groove. The length of the guide rod 3 is greater than the thickness of all the slides 1 and the locking plates 2.

[0032] The two locking plates 2 are located between the two sliding plates 1. When not clamped, the two locking plates 2 are staggered and can move independently with a gap between them. The opposing surfaces of the two locking plates 2 are uneven and can be provided with knurling or other structures, as long as it can be ensured that there is sufficient friction between the opposing surfaces of the two locking plates 2 so that no relative sliding occurs during clamping. The opposing surfaces of the sliding plate 1 and the locking plate 2 can also be provided with a concave-convex shape, which can also avoid relative sliding of the sliding plate 1 and the locking plate 2 during clamping, thereby achieving more stable locking.

[0033] The upper and lower widths of the slide 1 can be greater than the upper and lower widths of the locking piece, so that the two can fit better and the clamping is more stable; the locking piece 2 adopts an arc shape, and the slide 1 also adopts an arc shape that matches it.
