Description

Technical Field

[0001] The present invention relates to a three-wheeled vehicle, in particular to a tilt locking mechanism for a three-wheeled motorcycle. Background Art

[0002] Existing inverted tricycles use a suspension mechanism to connect the wheels and the frame, transmit the force and torque acting between the wheels and the frame, and buffer the impact force transmitted to the frame or the body by the uneven road surface. The suspension mechanism usually includes a main bracket, and a buffer mechanism, a steering mechanism, a locking mechanism and a swing mechanism arranged on the main bracket. Among them, the locking mechanism arranged on the main bracket cooperates with the swing mechanism so that the swing mechanism and the main bracket can rotate or be relatively fixed, so that the inverted tricycle can match various road conditions to achieve the best riding state.

[0003] The patent with publication number CN217575487U discloses a swing locking mechanism and a reverse tricycle. The swing locking mechanism comprises a first shell and a second shell connected to each other, wherein a transmission assembly and a driving assembly connected to the transmission assembly are arranged in the first shell, and a clamping assembly is arranged in the second shell, and a resisting member is arranged between the clamping assembly and the transmission assembly, and the transmission assembly drives the resisting member to move toward the clamping assembly so that the clamping assembly locks the locking plate. The setting form can be simplified and the reliability during use can be improved.

[0004] Although the locking mechanism can achieve the locking of 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 invention: The purpose of the present invention is to provide a tilt locking mechanism for a reverse three-wheeled motorcycle with a simple structure.

[0006] Technical solution: The tilt locking mechanism for an inverted three-wheeled motorcycle described in the present invention includes a slide plate, two locking plates and a clamping device for driving the slide plates to approach each other, wherein a slide plate is provided on the outer side 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 to be concave and convex, it is possible to avoid the two locking plates from sliding relative to each other to achieve locking when the two sliding plates clamp the locking plates. In this way, only one sliding plate is provided on the outside of each of the two locking plates, instead of providing a sliding plate on both sides of each locking plate to clamp the locking plates. That is, two sliding plates 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 sliding piece from falling off.

[0013] The limiting mechanism can be provided to 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 sliding plates and 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] The spring is arranged 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 too much moving space to be reserved for it, increasing the size of the entire vehicle.

[0024] Preferably, the sliding plate is in an arc shape matching 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 up and down width must be set larger than the arc, which increases the volume and cost.

[0026] Beneficial effect: Compared with the prior art, the present invention has the following significant beneficial effects: 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; Figure 2 This is a schematic diagram of the structure of this mechanism excluding the locking plate. DETAILED DESCRIPTION

[0028] As shown in the figure, because 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.

[0029] The tilt locking mechanism for an inverted three-wheeled motorcycle of the present invention comprises a slide plate 1, two locking plates 2 and a clamping device for driving the slide plates 1 to approach each other. A slide plate 1 is provided on the outer side of each of the two locking plates 2, and the opposing surfaces of the two locking plates 2 are concave-convex.

[0030] The clamping device can adopt the structure of the transmission assembly and drive assembly in CN217575487U for clamping the two slides 1, or can adopt the structure of hydraulic oil transmission commonly used in the brake mechanism of existing motorcycles or electric vehicles, and its structure will not be described in detail in this article; no matter what mechanism the clamping device adopts, there is a relatively fixed supporting mechanism, which is provided with at least two guide rods 3, and the slide 1 is connected to the guide rod 3 through sliding, and a total of two slides 1 are used, and a spring 4 is provided between the two slides 1 for separating the two, so that the slide 1 can be reset when the clamping device is not clamped, and then the two locking plates 2 are separated to avoid loss caused by mutual contact and friction; a limiting mechanism can also be provided at the end of the guide rod 3 to prevent the slide 1 from slipping, and the limiting mechanism can be a radially protruding flange, or an annular groove is provided at the end, and an annular baffle is clamped in the groove and other structures; the length of the guide rod 3 is greater than the thickness of all the slides 1 and the locking plates 2.

[0031] 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 arranged to be concave and convex, so that relative sliding between the sliding plate 1 and the locking plate 2 can be avoided during clamping, thereby achieving more stable locking.

[0032] The upper and lower widths of the slide plate 1 can be greater than the upper and lower widths of the locking plate, so that the two can fit better and the clamping is more stable; the locking plate 2 is arc-shaped, and the slide plate 1 also adopts an arc shape that matches it.
