Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle swaying mechanism. Background Technology

[0002] Vehicles are a collective term for both the word "car" and its unit "vehicle". A car is a wheeled vehicle used for transportation on land; the term "vehicle" comes from an ancient method of measuring vehicles.

[0003] The tricycle is a type of vehicle that became very popular after the 1930s, gradually replacing the rickshaw. Tricycles can be divided into human-powered tricycles, electric tricycles, children's tricycles, and battery-powered tricycles. A tricycle is a combination of a human-powered rickshaw and a bicycle, consisting of two parts: a front wheel that can turn, handlebars, a bell, brakes, pedals, and a seat, with a chain driving the rear wheel. It is equipped with a cargo box or flatbed for carrying passengers or goods.

[0004] In the existing technology, when a tricycle is driven, the two rear wheels rotate at a high speed. This causes the tricycle to tilt inward due to centrifugal force when turning, and the outer wheel is prone to leaving the ground, making it easy to overturn or skid, which poses a safety hazard.

[0005] In view of this, there is an urgent need for a vehicle swaying mechanism to solve the above problems. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A vehicle swaying mechanism includes: a carrier, on which a first rotating shaft, a first bevel gear, two second rotating shafts, two second bevel gears, two mounting plates, and a braking mechanism are disposed. The first rotating shaft and the two second rotating shafts are rotatably disposed on the carrier. The first bevel gear is coaxially disposed on the first rotating shaft. The two second bevel gears are respectively coaxially disposed on the two second rotating shafts. Both second bevel gears mesh with the first bevel gear.

[0009] The two mounting plates are respectively disposed on the two second rotating shafts. The mounting plates are provided with mounting positions for mounting wheels. The wheels at the mounting positions are not coaxial with the second rotating shafts.

[0010] The braking mechanism is used to brake the first rotating shaft.

[0011] Two second rotating shafts are respectively disposed on both sides of the first rotating shaft, and the two second rotating shafts are coaxially disposed; the axis of the first rotating shaft is perpendicular to the axis of the second rotating shaft.

[0012] The carrier is provided with a third bevel gear, which is opposite to and coaxial with the first bevel gear, and the third bevel gear meshes with both second bevel gears.

[0013] The carrier consists of two opposing housings, with the first rotating shaft, the first bevel gear, two second rotating shafts, and two second bevel gears all disposed between the two housings.

[0014] The braking mechanism includes a braking component and a driving component. The braking component is slidably disposed on the carrier, and the driving component is used to drive the braking component to move toward or away from the first rotating shaft.

[0015] A limiting surface is provided on the circumferential side of the first rotating shaft. The driving member drives the braking member to move towards the side closer to the first rotating shaft, so that the braking member moves to the limiting surface.

[0016] The limiting surface is provided in two ways, and the two limiting surfaces are arranged opposite to each other. The braking element is U-shaped, and the opening of the braking element faces the first rotating shaft. The driving element drives the braking element to move towards the side closer to the first rotating shaft, so that the two ends of the braking element move to the two limiting surfaces respectively.

[0017] The first rotating shaft has a limiting hole on its annular side, and the driving member drives the braking member to insert into or pull out of the limiting hole.

[0018] The driving component includes a motor and a screw. The motor is mounted on the carrier and is used to drive the screw to rotate. The screw passes through the braking component and is threadedly connected to the braking component.

[0019] The driving component is a cylinder, and the braking component is located at the output end of the cylinder.

[0020] The above-described structure of this utility model can achieve the following beneficial effects:

[0021] In use, the two wheels are installed at their respective mounting positions on the two mounting plates, and the carrier is placed on or integrated with the rear frame. When the vehicle turns, as the vehicle body tilts towards the inside of the curve, the inner wheel will relatively lift upwards, causing the mounting plate on the same side to lift upwards. This causes the second shaft and second bevel gear on the same side to rotate. Through the transmission of the first bevel gear, the second bevel gear and second shaft on the other side rotate in the opposite direction, causing the mounting position of the other mounting plate to flip downwards. This causes the outer wheel to swing downwards, compensating for the distance the outer wheel lifts upwards due to the vehicle body tilt, ensuring that the outer wheel is always in contact with the road surface. This ensures that both the inner and outer wheels are in contact with the road surface, thus maintaining vehicle stability. Furthermore, by incorporating a braking mechanism, when driving on straight roads, small curves, or at low speeds, the braking mechanism can brake the first shaft, preventing the two second shafts from rotating and preventing the two wheels from moving relative to the carrier in a direction perpendicular to the horizontal plane, thus ensuring vehicle stability. This application allows for mode selection via the braking mechanism based on actual road conditions, further enhancing the driving experience and enjoyment. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0030] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0031] like Figures 1-3 As shown, a vehicle swaying mechanism includes: a carrier 1, on which a first rotating shaft 2, a first bevel gear 3, two second rotating shafts 4, two second bevel gears 5, two mounting plates 6 and a braking mechanism are disposed. The first rotating shaft 2 and the two second rotating shafts 4 are rotatably disposed on the carrier 1. The first bevel gear 3 is coaxially disposed on the first rotating shaft 2. The two second bevel gears 5 are coaxially disposed on the two second rotating shafts 4 respectively. Both second bevel gears 5 mesh with the first bevel gear 3.

[0032] Two mounting plates 6 are respectively set on two second rotating shafts 4. The mounting plates 6 are provided with mounting positions for installing wheels. The wheels at the mounting positions are not coaxial with the second rotating shafts 4.

[0033] The braking mechanism is used to brake the first rotating shaft 2.

[0034] Based on the above structure, in use, the two wheels are respectively installed at the installation positions of the two mounting plates 6 (in this embodiment, one end of the mounting plate 6 is connected to the second rotating shaft 3, and the other end is used to open mounting holes for installing the wheels), and the carrier 1 is placed on the rear frame or integrated with the rear frame; when the vehicle turns, because the vehicle body tilts to the inside of the curve, the inner wheel will move upward relative to the vehicle body, causing the mounting plate 6 on the same side to lift upward, causing the second rotating shaft 3 and the second bevel gear 5 on the same side to rotate. Through the transmission of the first bevel gear, the second bevel gear 5 and the second rotating shaft 3 on the other side rotate in the opposite direction, causing the installation position of the other mounting plate 6 to flip downward, causing the outer wheel to swing downward relative to the vehicle body, compensating for the downward movement caused by the vehicle body. The tilting mechanism causes the outer wheel to lift upwards a certain distance, ensuring that the outer wheel remains in contact with the road surface, and that both the inner and outer wheels are in contact with the road surface, thus maintaining vehicle stability. Furthermore, by incorporating a braking mechanism, when driving on straight roads, on tight curves, or at low speeds, the first axle 2 can be braked, preventing the two second axles 4 from rotating and preventing the two wheels from moving relative to the carrier 1 in a direction perpendicular to the horizontal plane, thus ensuring vehicle stability. This application allows for mode selection via the braking mechanism based on actual road conditions (which can be combined with existing intelligent recognition or sensor structures to achieve automatic mode switching), further enhancing the driving experience and enjoyment, and ensuring passenger safety during high-speed cornering.

[0035] like Figure 3 As shown, two second rotating shafts 4 are respectively set on both sides of the first rotating shaft 2, and the two second rotating shafts 4 are coaxially arranged; the axis of the first rotating shaft 2 is perpendicular to the axis of the second rotating shaft 4, which facilitates the processing of the first bevel gear 3 and the second bevel gear 5; and both the first rotating shaft 2 and the second rotating shaft 4 are set on the carrier 1 through bearings, ensuring that the first rotating shaft 2 and the second rotating shaft 4 can rotate more stably on the carrier 1.

[0036] A further optimization involves a third bevel gear (not shown in the attached diagram) mounted on the carrier 1. This third bevel gear can be fitted onto the first rotating shaft 2, but it does not rotate synchronously with the first rotating shaft 2. The third bevel gear is opposite to and coaxial with the first bevel gear 3. The third bevel gear meshes with both second bevel gears 5. Thus, the first bevel gear 3, the two second bevel gears 5, and the third bevel gear are arranged in a rectangular shape and mesh sequentially (the two second bevel gears 5 rotate in opposite directions, and the first bevel gear 3 and the third bevel gear rotate in opposite directions). The third bevel gear acts as a transition, ensuring the stability of the rotation of the two second bevel gears 5.

[0037] like Figures 1-3As shown, the carrier 1 consists of two opposing housings. The first rotating shaft 2, the first bevel gear 3, the two second rotating shafts 4, and the two second bevel gears 5 are all located between the two housings. The two housings are fixed together by bolts. The internal parts are enclosed by the two housings to avoid interfering with the transmission between the bevel gears.

[0038] like Figures 3-5 As shown, the braking mechanism includes a brake element 7 and a driving element. The brake element 7 is slidably mounted on the carrier 1. The driving element drives the brake element 7 to move towards or away from the first rotating shaft 2. When the brake element 7 contacts the first rotating shaft 2, friction prevents the first rotating shaft 2 from rotating, thus achieving a braking effect. Specifically, a limiting surface 21 can be provided on the annular side of the first rotating shaft 2. The driving element drives the brake element 7 to move towards the side closer to the first rotating shaft 2, causing the brake element 7 to move to the limiting surface 21. (The limiting surface 21 is preferably a plane) When it is necessary to brake the first rotating shaft 2, the driving component drives the braking component 7 to move to one side of the first rotating shaft 2, so that the braking component 7 moves to the limiting surface 21. The braking component 7 fits against the limiting surface 21, so that the first rotating shaft 2 cannot rotate, thus achieving the braking effect. When the first rotating shaft 2 is braked, the two wheels are in a normal driving state, so that the braking component 7 can move to the limiting surface 21. That is to say, when the first rotating shaft 2 rotates, there is an angle at which the braking component 7 can move to the limiting surface 21.

[0039] Further optimizations include, for example Figure 4 As shown, in this embodiment, two limiting surfaces 21 are preferably provided, and the two limiting surfaces 21 are arranged opposite to each other. The brake member 7 is U-shaped, and the opening of the brake member 7 faces the first rotating shaft 2. The driving member drives the brake member 7 to move towards the side closer to the first rotating shaft 2, so that the two ends of the brake member 7 move to the two limiting surfaces 21 respectively. By inserting the brake member 7 into the first rotating shaft 2, the two ends of the brake member 7 are respectively locked at the two limiting surfaces 21, thereby improving the stability of braking.

[0040] In addition to setting a limiting surface 21 on the annular side of the first rotating shaft 2, a limiting hole can also be set on the annular side of the first rotating shaft 2. When the limiting hole faces the brake member 7, the limiting hole is located on the movement path of the brake member 7. The driving member drives the brake member 7 to insert into the limiting hole or pull it out of the limiting hole. After the brake member 7 is inserted into the limiting hole, the rotation of the first rotating shaft 2 is restricted, thereby achieving braking of the first rotating shaft 2.

[0041] like Figure 5As shown, the driving component includes a motor 8 and a screw 9. The motor 8 is mounted on the carrier 1 and is used to drive the screw 9 to rotate. The screw 9 passes through the brake 7 and is threadedly connected to the brake 7. Thus, by driving the screw 9 to rotate through the motor 8, the brake 7 moves linearly along the axis of the screw 9 (the brake 7 is slidably mounted on the carrier 1, so that the brake 7 can only move linearly and cannot rotate), causing the brake 7 to move toward or away from the first rotating shaft 2.

[0042] In addition, the driving component can also be a cylinder, and the braking component 7 is located at the output end of the cylinder. By the work done by the cylinder, the braking component 7 is driven to move closer to or away from the first rotating shaft 2.

[0043] In summary, during use, the two wheels are respectively installed at the mounting positions of the two mounting plates 6 (in this embodiment, one end of the mounting plate 6 is connected to the second rotating shaft 3, and the other end is used to open mounting holes for installing the wheels), and the carrier 1 is placed on the rear frame or integrated with the rear frame; when the vehicle turns, because the vehicle body tilts towards the inside of the curve, the inner wheel will relatively lift upwards, causing the mounting plate 6 on the same side to lift upwards, causing the second rotating shaft 3 and the second bevel gear 5 on the same side to rotate. Through the transmission of the first bevel gear, the second bevel gear 5 and the second rotating shaft 3 on the other side rotate in the opposite direction, causing the mounting position of the other mounting plate 6 to flip downwards, causing the outer wheel to swing downwards. The system compensates for the distance the outer wheels lift due to vehicle tilt, ensuring that the outer wheels remain in contact with the road surface, and that both the inner and outer wheels are in contact with the road, thus maintaining vehicle stability. Furthermore, by incorporating a braking mechanism, when driving on straight roads, small curves, or at low speeds, the first axle 2 can be braked, preventing the two second axles 4 from rotating and preventing the two wheels from moving relative to the carrier 1 in a direction perpendicular to the horizontal plane, thus ensuring vehicle stability. This application can also select a driving mode based on actual road conditions through the braking mechanism (which can be combined with existing intelligent recognition or sensor structures to achieve automatic mode switching), further enhancing the driving experience and enjoyment.

[0044] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
