[0023] See also Figure 1-4 , further illustrate the embodiments of the present utility model;

[0024] like Figure 1As shown, an engine P gear anti-skid mechanism includes a shift drum 4, one end of which is transmission-connected with a locking member, the locking member is rotationally connected to the engine casing (not shown), and a gear member is provided next to the shift drum 4, the locking member is meshingly connected to the gear member.

[0025] like Figure 1-4 As shown, the locking member includes a locking plate 3, which is crescent-shaped and matches the shape of the gear member, so that the locking plate 3 can quickly clamp or loosen the gear member. The locking plate 3 is transmission-connected to one end of the speed change drum 4, and a mounting shaft 33 is fixed to the middle of the surface of the locking plate 3, and the mounting shaft 33 is rotationally connected to the engine casing. The lower end of the locking plate 3 is integrally formed with multiple tooth blocks 31 facing inward, and the multiple tooth blocks 31 are meshed with the gear member.

[0026] like Figure 2-4 As shown, a mounting hole 32 is opened above the surface of the locking plate 3, and an inner wall of the mounting hole 32 away from the gear part has an inner recess 321. A shift block 41 is fixed to the surface of one end of the speed change drum 4, and the shift block 41 is transmission-connected to the inner recess 321, so that the locking plate 3 can be rotated in the engine casing so that the locking plate 3 can lock or release the gear part.

[0027] like Figure 1-2 As shown, the gear member includes a rotating shaft 1 and a gear 2. The rotating shaft 1 is rotatably connected to the engine casing, the gear 2 is sleeved and fixed on the rotating shaft 1, and the gear 2 is meshed and connected with multiple gear blocks 31. One side of the rotating shaft 1 is provided with a rotating shaft 2 6 rotatably connected to the engine casing, and the gear 2 7 is sleeved and fixed on the outside of the rotating shaft 2 6. The rotating shaft 3 9 is provided on one side of the rotating shaft 2 6 rotatably connected to the engine casing, and the gear 3 10 is sleeved and fixed on the outside of the rotating shaft 3 9. The rotating shaft 3 9 is connected to the wheels through transmission components to provide power for the wheels.

[0028] like Figure 1-3 As shown, a limiting sleeve 5 is fixed to one end of the speed change drum 4 close to the locking plate 3 . The limiting sleeve 5 is located outside the locking plate 3 and is used to limit the locking plate 3 .

[0029] like Figure 1 As shown, a plurality of limit grooves are provided at one end of the shift drum 4 away from the locking member, and a locking member 8 is inserted into one of the limit grooves. The locking member 8 adopts the existing technology. The locking member 8 includes a limit pin with a hollow interior and a spring installed in the limit pin. A steel ball is fixed at the end of the spring, and the steel ball is bounced into one of the limit grooves by the spring. The locking member 8 is installed in the engine casing through a driving member. The driving member can be an electric cylinder, a hydraulic cylinder electric push rod, or the like installed between the engine casing and the limit pin, which can drive the limit pin to move linearly.

[0030] In this embodiment, Figure 1-2As shown, when the vehicle is parked in the P gear, the locking member 8, driven by the driving member, enters the corresponding limiting groove on the shift drum 4, limiting the shift drum 4 and preventing the vehicle from shifting gears. At this time, the locking plate 3 in the anti-skid mechanism meshes with the gear 1 2 in the gear member through the tooth block 31, thereby preventing the rotating shaft 1 and the gear 1 2 from rotating. The gear 1 2 is meshed and connected with the gear 2 7, and the gear 2 7 is meshed and connected with the gear 3 10. Therefore, the rotating shaft 3 9 is prevented from rotating, and further the wheels indirectly connected to the rotating shaft 3 9 are prevented from rotating, thereby preventing the vehicle from slipping when in the P gear.

[0031] When the vehicle needs to be started, the driving member is started to drive the locking member 8 to move upward, releasing the limit of the speed change drum 4. When the engine is working, the speed change drum 4 rotates due to the circulation of the hydraulic oil in the engine and the change of the kinetic energy. When the speed change drum 4 rotates, it drives the shift block 41 to rotate. The shift block 41 shifts the inner recess 321 in the mounting hole 32, so that the tooth block 31 at the lower end of the locking plate 3 is separated from the gear 1 2, thereby realizing the transmission of the locking plate 3 by the speed change drum 4, so that the locking plate 3 rotates in the engine casing. Thereafter, the rotation of the gear 1 2, the gear 2 7, and the gear 3 10 will no longer be restricted. Therefore, when the rotating shaft 3 9 rotates, the wheels can be indirectly driven to rotate. At this time, the existence of the anti-skid mechanism does not affect the normal driving of the vehicle, and other gears can be shifted to facilitate driving.

[0032] If the vehicle needs to be parked, it is shifted to P gear. During this process, the shift drum 4 drives the shift block 41 to rotate to press down the inner recess 321, so that the tooth block 31 at the lower end of the locking plate 3 is engaged with the gear 2 to prevent the gear 2 from rotating, thereby preventing the wheel from rotating. The specific operation will not be repeated here. Please refer to the description in the vehicle parking state to achieve the purpose of preventing the vehicle from sliding when it is in P gear, thereby improving the safety of the vehicle when parking.

[0033] The present utility model also provides an engine, including the above-mentioned engine P gear anti-skid mechanism. When the vehicle is parked and shifted to P gear, the transmission drum 4 transmits the locking member, so that the locking member is engaged with the gear member to prevent the gear member from rotating, thereby preventing the wheel from rotating, achieving the purpose of preventing the vehicle from slipping when in P gear, and improving the safety of the vehicle when parking.

[0034] The present invention further provides a three-wheeled motorcycle, comprising the above-mentioned engine. When the vehicle is parked and shifted into the P gear, the transmission drum 4 transmits a locking member, so that the locking member is engaged with the gear member to prevent the gear member from rotating, thereby preventing the wheels from rotating, thereby achieving the purpose of preventing the vehicle from slipping when in the P gear and improving the safety of the vehicle when parked.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
