Description

Technical Field

[0001] The utility model relates to the technical field of all-terrain vehicle parking systems, in particular to an all-terrain vehicle electric parking system. Background Art

[0002] The parking system usually refers to the manual brake installed on motor vehicles, referred to as the handbrake, which is used to stabilize the vehicle after it stops to prevent accidents caused by rolling when the vehicle is parked on a slope.

[0003] The traditional parking brake device includes handbrake handle, brake flexible shaft, brake, brake disc and other components. The handbrake handle is installed at the driver's position and is connected to the brake through the brake flexible shaft. When parking brake is required, the driver pulls the handbrake handle to act on the brake through the brake flexible shaft, pulling the mechanical mechanism to make the brake press the brake disc to form a braking effect.

[0004] Most of the existing technologies use electronic parking brake systems.

[0005] An all-terrain vehicle is a vehicle that can travel on any terrain and can move freely on terrain where ordinary vehicles are difficult to maneuver. Therefore, its usage environment is mostly on sloped and uneven ground.

[0006] In the prior art, the parking brake of the vehicle is mostly performed by locking the brake disc of the vehicle to prevent the vehicle from rolling, etc. However, since most of the use scenarios of all-terrain vehicles have slopes with large slopes, the all-terrain vehicles will have the potential energy to slide downward under the influence of gravity after stopping. Therefore, when clamping and locking the brake disc to achieve the purpose of parking, a large and continuous pressure is required. In addition, since the self-weight and center of gravity of the all-terrain vehicle are high, when the vehicle stops on a sloped ground, it is easy for the vehicle to slide downward due to gravity;

[0007] When a vehicle slides down due to gravity, it is easy for the brake caliper and the brake disc to rub against each other, causing damage to the brake disc and the brake caliper. Therefore, it is difficult to effectively park a vehicle on a slope by locking the brake disc with the brake caliper to achieve parking braking. Utility Model Content

[0008] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide an electric parking system for an all-terrain vehicle so as to solve the technical problems mentioned in the above background technology.

[0009] The above technical objectives of the utility model are achieved through the following technical solutions:

[0010] An electric parking system for an all-terrain vehicle comprises a bridge frame, extension frames are rotatably arranged at both ends of the bridge frame, a rotating shaft is fixedly arranged at one end of the extending frame, a mounting ring is sleeved on the upper end of the rotating shaft, a positioning ring is fixedly arranged on one side of the mounting ring, a rotating shaft is arranged inside the positioning ring, a constant velocity universal joint is arranged at one end of the rotating shaft close to the extending frame, and a wheel rim is arranged at one end of the rotating shaft away from the extending frame;

[0011] A connecting platform is fixedly mounted on the outer surface of the positioning ring, a universal connector is arranged on the top of the connecting platform, and a steering link is connected to one side of the universal connector;

[0012] A telescopic platform is slidably provided at the upper end of the bridge frame, a universal joint is provided at the upper end of the telescopic platform, and two connecting ends of the universal joint are respectively provided with two external screws with opposite thread directions.

[0013] Furthermore, one side of the two steering links is provided with an internal threaded tube, and the two internal threaded tubes are respectively threadedly matched with the two groups of external screws.

[0014] Furthermore, the telescopic platform includes a pneumatic support rod, the top end of the pneumatic support rod is provided with an L-shaped mounting plate, and a rotating hole is opened inside the L-shaped mounting plate.

[0015] Furthermore, the universal joint includes a ball head and a ball cover, an electromagnetic locking ring is arranged inside the ball cover, the ball head is embedded in the ball cover, and fixing holes for installing an external screw are arranged at ends of the ball head and the ball cover that are away from each other.

[0016] Furthermore, a driving gear is disposed on the outer surface of the ball cover, a linkage gear meshing with the driving gear is disposed on the upper end of the L-shaped mounting plate, and a motor is disposed at one end of the linkage gear.

[0017] Furthermore, the fixing hole is connected to the external screw via a spline.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] 1. The electric parking system for an all-terrain vehicle, when parking the vehicle, rotates the universal joint so that the external threads on both sides simultaneously push the two sets of steering links to the two sides respectively, and then pushes the wheel rim to two different directions through the steering link, so that the wheel rim forms an inner eight-shaped or outer eight-shaped shape. When the vehicle stops on a sloped ground, the eight-shaped wheel rim will push the soil, so that a large amount of soil is gathered on the force-bearing side of the wheel rim, thereby increasing the friction between the wheel rim and the ground, so as to achieve the purpose of parking;

[0020] 2. The electric parking system for an all-terrain vehicle can always keep the two outer screws in a synchronous driving state through the setting of the universal joint when the linear directions of the two extension rods are not in the same straight line, that is, when the heights of the two wheel rims are different, so that the two wheel rims can be in an eight-shaped shape even on uneven ground, thereby effectively improving the applicability of the parking system, so that the all-terrain vehicle can be stopped and parked on a variety of different road surfaces;

[0021] 3. This all-terrain vehicle electric parking system, when parking is required, uses an electromagnetic lock to clamp the ball head so that the ball head is fixedly connected to the ball cover. At this time, the ball head can rotate with the ball cover, and then during the rotation of the ball cover, it can simultaneously control the outer screws on both sides so that the two outer screws can rotate simultaneously and synchronously, thereby achieving the effect of simultaneously driving the movement of the two steering links.

DETAILED DESCRIPTION

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] Example:

[0033] Reference Figure 1-7 The utility model discloses an electric parking system for an all-terrain vehicle, comprising a bridge frame 1, extension frames 2 are rotatably arranged at both ends of the bridge frame 1, a rotating shaft 3 is fixedly arranged at one end of the extending frame 2, a mounting ring 4 is sleeved on the upper end of the rotating shaft 3, a positioning ring 5 is fixedly arranged on one side of the mounting ring 4, a rotating shaft 6 is arranged inside the positioning ring 5, a constant velocity universal joint is arranged at one end of the rotating shaft 6 close to the extending frame 2, and a wheel rim 7 is arranged at one end of the rotating shaft 6 away from the extending frame 2;

[0034] A connecting platform 8 is fixedly mounted on the outer surface of the positioning ring 5, a universal connector 9 is disposed on the top of the connecting platform 8, and a steering link 10 is connected to one side of the universal connector 9;

[0035] A telescopic platform 11 is slidably provided at the upper end of the bridge frame 1 , a universal joint 12 is provided at the upper end of the telescopic platform 11 , and two connecting ends of the universal joint 12 are respectively provided with two external screws 13 with opposite thread directions.

[0036] In this embodiment, the bridge frame 1 is used to connect the two extension frames 2, and the two extension frames 2 are used to install two sets of mounting rings 4 and positioning rings 5 ​​respectively, so that the wheel rims 7 on both sides are respectively connected to the two extension frames 2, and the two wheel rims 7 can be turned in different directions respectively, and the bottom end of the telescopic platform 11 is slidably connected to the telescopic platform 11 to improve the stability of the telescopic platform 11. After the two steering links 10 are extended to both sides respectively, the telescopic platform can always support the universal joint.

[0037] When the vehicle is parked, the universal joint 12 is rotated so that the external threads on both sides simultaneously push the two sets of steering links 10 to both sides respectively, and then the steering links 10 push the wheel rim 7 to two different directions, so that the wheel rim 7 forms an inner toe shape or an outer toe shape;

[0038] Specifically, when the vehicle slides down the slope, the outer openings of the two wheel rims 7 are in the same direction as the sliding direction of the vehicle, such as Figure 7 As shown, A is the direction in which the vehicle slides;

[0039] At this time, when the vehicle stops on the sloped ground, the vehicle slides downward under the influence of gravity. At this time, the wheel rim 7 in the shape of an eight pushes the soil, so that a large amount of soil gathers on the force-bearing side of the wheel rim 7, thereby increasing the friction between the wheel rim 7 and the ground, so that the gravity of the vehicle itself is gathered at the position of the wheel rim, and then the vehicle is fixed by the wheel rim and the soil, so as to achieve the purpose of parking;

[0040] Compared with the existing technology, it can avoid the brake disc from being subjected to stress for a long time, as well as the wear caused by the brake being locked for a long time, and can effectively avoid the friction between the brake caliper and the brake disc, which may cause damage to the brake disc and the brake caliper. It can greatly improve the service life of the brake and can effectively park on a sloped ground.

[0041] In a further preferred embodiment of the present invention, Figure 1-7 As shown, one side of the two steering links 10 is provided with an internal threaded tube 14 , and the two internal threaded tubes 14 are threadedly matched with the two groups of external screws 13 respectively.

[0042] In this embodiment, by setting the internal threaded tube 14, when the universal joint 12 rotates, the two external screws 13 are driven to rotate. Since the spiral directions of the two external screws 13 are opposite, and the two internal threaded tubes 14 are respectively threadedly matched with the two external screws 13, when the two external screws 13 rotate at the same time, the two steering links 10 can be pushed to rotate in two different directions, so as to achieve the purpose of forming an eight-shaped structure of the two wheels, and the eight-shaped opening of the wheel is in the same direction as the sliding direction of the vehicle, such as Figure 7 As shown, during the sliding process of the vehicle, soil can be piled on the inner sides of the two wheel rims 7 to increase the friction between the vehicle and the ground, so as to achieve the effect of parking and preventing the vehicle from sliding down excessively.

[0043] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the telescopic platform 11 includes a pneumatic support rod 111 , a top end of the pneumatic support rod 111 is provided with an L-shaped mounting plate 112 , and a rotation hole 113 is opened inside the L-shaped mounting plate 112 .

[0044] In this embodiment, the bottom end of the pneumatic support rod 111 is always in contact with the top of the bridge frame 1 and can slide on the top of the bridge frame 1. The L-shaped mounting plate 112 is used to install the universal joint 12 in cooperation with the rotating hole 113 to improve the stability of the universal joint during rotation. At the same time, the pneumatic support rod 111 is provided to provide support force for the universal joint 12, so that the universal joint 12 is in a horizontal state when not subject to force. When the straight directions of the two extension rods are not in the same straight line, that is, the heights of the two wheel rims 7 are different, the universal joint can always keep the two outer screws 13 in a synchronously driven state through the setting of the universal joint, so that the two wheel rims 7 can be in an eight-shaped shape even on uneven ground, thereby effectively improving the applicability of the parking system, so that the all-terrain vehicle can be stopped and parked on a variety of different road surfaces.

[0045] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the universal joint 12 includes a ball head 121 and a ball cover 122. An electromagnetic locking ring 126 is arranged inside the ball cover 122. The ball head 121 is embedded in the ball cover 122. The ends of the ball head 121 and the ball cover 122 that are away from each other are both provided with fixing holes 123 for installing the external screw 13.

[0046] In this embodiment, the ball head 121 is embedded in the interior of the ball cover 122 to form a multi-angle universal joint 12, and the electromagnetic lock ring 126 is set inside the ball cover 122. When parking is required, the electromagnetic lock ring 126 locks the ball head 121 so that the ball head 121 is fixedly connected to the ball cover 122. At this time, the ball head 121 can rotate with the ball cover 122, and then during the rotation of the ball cover 122, the outer screws 13 on both sides can be controlled at the same time, so that the two outer screws 13 can rotate simultaneously and synchronously, thereby achieving the effect of driving the two steering links 10 to move at the same time, and after parking is completed, that is, after the wheel rims on both sides have deflected to both sides, the electromagnetic lock ring 126 can be unlocked, so that parking is done by the vehicle's own gravity and the friction between the tires and the soil, which can effectively save the electric energy inside the vehicle to increase the power supply time of the internal power supply of the vehicle.

[0047] In a further preferred embodiment of the present invention, Figure 1-7 As shown, a driving gear 124 is disposed on the outer surface of the ball cover 122 , a linkage gear 125 meshing with the driving gear 124 is disposed on the upper end of the L-shaped mounting plate 112 , and a motor is disposed at one end of the linkage gear 125 .

[0048] In this embodiment, the motor is used to control the linkage gear 125 to rotate, and the linkage gear 125 is then used to rotate the driving gear 124, so that the ball cover 122 can be well controlled to rotate, thereby achieving the purpose of controlling the rotation of the outer screw 13.

[0049] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the fixing hole 123 is connected to the external screw 13 via a spline.

[0050] In this embodiment, since the fixing hole 123 is connected to the outer screw 13 via a spline, the ball cover 122 can drive the outer screw 13 to rotate when it rotates, and it is also convenient to replace the outer screw 13, thereby effectively improving the efficiency of maintenance and replacement when maintaining the device.

[0051] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
