Description

Technical Field

[0001] This utility model belongs to the technical field of driving training auxiliary equipment, specifically relating to a movable anti-collision training pole mechanism for vehicle driving training. Background Technology

[0002] As automobiles are important means of transportation, driving skills have become a crucial skill to learn. Training poles are essential auxiliary devices frequently used in driving instruction, primarily for limiting and positioning in training areas. High frequency of use, large number of poles, long service life, and good adaptability are key considerations when selecting training poles. Currently used training poles are mostly fixed structures, consisting of a training pole and a base inserted into its base. The base is generally a relatively flat, frustum-shaped structure, with the training pole fixedly inserted into the center groove of the base. The outside of the training pole is usually covered with red and white reflective stickers. Existing training pole structures are relatively simple and have poor adaptability. When new learners are practicing, vehicles easily knock over the training poles, causing them to break due to their weight hitting the ground, or the wheels may run over the base, causing it to shatter. This results in training poles being easily damaged during practice, requiring frequent replacements and significantly increasing training costs. Therefore, it is necessary to design a new type of training pole that can avoid frequent damage to reduce the cost of driving instruction. Utility Model Content

[0003] In view of the above situation, this utility model provides a movable anti-collision training pole mechanism for vehicle driving training, which can greatly reduce the occurrence of training pole damage during driving training and effectively save vehicle driving training costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A movable anti-collision training pole mechanism for vehicle driving training includes a base and a pole body. A helical spring is also provided between the pole body and the base. An upper spring seat is fixedly connected to the lower end of the pole body, and a lower spring seat is fixedly connected to the center of the base. The upper end of the helical spring is fixedly connected to the upper spring seat, and the lower end of the helical spring is detachably and movably inserted into the lower spring seat. Multiple omnidirectional rolling bullseye rollers are arranged in a ring below the periphery of the base. Each bullseye roller includes a spherical ball for allowing the base to slide on the ground, and a roller body for accommodating the spherical ball. The bottom of the spherical ball protrudes movably from the bottom of the roller body, and the top of the roller body is fixedly connected to the base. A braking device for braking or releasing the spherical ball is provided inside the upper part of the roller body. Preferably, the roller body is an inverted barrel-shaped structure with an open bottom, and an annular mounting groove is provided on the inner side wall of the bottom of the roller body. The spherical balls are rotatably installed in the mounting groove by ball bearings.

[0005] Furthermore, the ball bearing includes a cup-shaped roller bushing with openings at both the top and bottom, the upper opening having a smaller diameter than the lower opening. The cup-shaped roller bushing is a sheet metal part with a certain degree of elasticity made of stainless steel. The spherical balls are rotatably embedded inside the cup-shaped roller bushing, and several small balls are evenly distributed between the spherical balls and the inner wall of the cup-shaped roller bushing. The upper and lower ends of the cup-shaped roller bushing are respectively engaged with retaining rings and secured to the inner side of the mounting groove. The top and bottom of the spherical balls protrude from the upper and lower openings of the cup-shaped roller bushing, respectively.

[0006] Furthermore, the braking device includes a braking assembly and a control assembly. The braking assembly includes an inverted bowl-shaped brake pad that is adapted to the top of the spherical ball, and a telescopic rod that is vertically fixed to the center of the top surface of the brake pad. The upper end of the telescopic rod slides through the center hole of the top plate of the roller body and is connected to a liftable limiting cover. A travel space is left between the top plate of the roller body and the base for the limiting cover to move up and down. A top pressure spring is also coaxially sleeved on the outer side of the lower end of the telescopic rod. The top pressure spring can extend and press against the top surface of the brake pad and the top plate of the roller body. When the top pressure spring presses down on the brake pad, it can achieve damping braking of the spherical ball and prevent the base from shifting when the training rod is slightly impacted.

[0007] Furthermore, the control component includes a lifting rod hinged above the center of the limiting top cover. The upper end of the lifting rod passes through an opening at the bottom of the base. A pry lever is rotatably hinged to the upper end of the lifting rod. The base is a hollow, frustum-shaped conical structure. The outer end of the pry lever extends through a vertical elongated hole on the side wall of the base. The central fulcrum of the pry lever is rotatably hinged to the outer side wall of the base via a hinge seat. A pry handle is connected to the outer end of the pry lever. When the pry handle is pressed down, the lifting rod can lift the brake pad away from the spherical ball. When the wheel runs over the pry handle, the base can slide away from the vehicle in time to avoid the base being crushed.

[0008] Furthermore, a strong magnetic ring is provided around the outer periphery of the bottom opening of the base. The strong magnetic ring is fixedly embedded in the lower surface of the base. Both the strong magnetic ring and the limiting top cover are made of strong neodymium magnets. The downward pressing force of the top spring is greater than the magnetic attraction of the strong magnetic ring to the limiting top cover. When the lifting rod drives the brake pad to a certain height, the strong magnetic ring can strongly attract the limiting top cover to ensure the reliable and continuous release of the brake pad to the spherical ball.

[0009] Preferably, three bullseye rollers are evenly spaced at 120° intervals below the edge of the base. Three sets of braking devices are correspondingly arranged above the three bullseye rollers. The levers corresponding to the three sets of braking devices are integrally connected to form a ring that can be raised and lowered. The ring is suspended on the outer periphery of the base through the levers of the three sets of braking devices. When the wheels run over the suspended ring, the ring will be pressed down as a whole, forcing the three sets of braking devices to release simultaneously.

[0010] Preferably, a strong magnetic block is fixedly connected to the lower end of the helical spring, and a strong magnetic sheet is fixedly provided at the upper end of the lower spring seat. Both the strong magnetic block and the strong magnetic sheet are made of strong neodymium magnets. When the lower end of the helical spring is inserted into the lower spring seat, the strong magnetic sheet can strongly attract the strong magnetic block, enhancing the bonding force between the helical spring and the lower spring seat. This ensures that the lower end of the helical spring can be relatively securely inserted into the upper slot of the lower spring seat, so that the training rod will not easily tip over after being subjected to a slight impact, but will instead exhibit a slight elastic sway.

[0011] Furthermore, the upper spring seat has an upper insertion port and a lower insertion port at its top and bottom, respectively. The lower end of the rod is fixedly inserted into the upper insertion port. The lower spring seat has an upper slot and a lower slot at its top and bottom, respectively. The central boss integrally formed on the top of the base is fixedly inserted into the lower slot. The upper end of the helical spring is fixedly inserted into the lower insertion port of the upper spring seat, and the lower end of the helical spring is movably inserted into the upper slot of the lower spring seat.

[0012] Furthermore, the upper end of the helical spring is tightly fitted with the inner wall of the lower insertion port of the upper spring seat, and a protruding plug is integrally formed below the center of the lower insertion port. The outer wall of the protruding plug is tightly pressed and supported inside the helical spring. The lower end of the helical spring is loosely fitted with the inner wall of the upper slot of the lower spring seat, with the looseness preferably being 0.2-0.5mm, to ensure that when the training rod is subjected to a relatively violent impact, the lower end of the helical spring can smoothly disengage and pop out from the upper slot.

[0013] This utility model also includes other components that enable its normal use, all of which are conventional means in the field. In addition, devices or components not limited in this utility model, such as the rod body and base of the training bar, as well as the helical spring, upper spring seat, lower spring seat, top compression spring, brake pad and powerful neodymium magnet, all adopt the prior art in the field.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a movable anti-collision training pole mechanism for vehicle driving training. Through a flexible and separable plug-in structure between the training pole and its base, the pole will not easily tip over after a minor collision with a vehicle, but will instead exhibit slight elastic swaying. When the pole is subjected to a relatively violent impact, it can completely detach from the base, effectively preventing breakage. Furthermore, by adding omnidirectional casters under the base and a brake device on the outer ring of the base that enables spherical ball bearing braking or release, the base of the training pole can automatically evacuate and avoid being run over by a vehicle, protecting the base from breakage as much as possible. This effectively solves the problem of frequent damage to training poles in existing technologies and helps reduce vehicle driving training costs. Attached Figure Description

[0018] Example 1 like Figure 1-5 As shown, a movable anti-collision training pole mechanism for vehicle driving training includes a pole body 1 and a base 2. A helical spring 3 is also provided between the pole body and the base. An upper spring seat 4 is fixedly connected to the lower end of the pole body, and a lower spring seat 5 is fixedly connected to the center of the base. The upper end of the helical spring is fixedly connected to the upper spring seat, and the lower end of the helical spring is detachably and movably inserted into the lower spring seat. Three omnidirectional rolling bullseye rollers 6 are arranged in a ring at 120° intervals below the periphery of the base. The bullseye rollers include features for enabling the base to... The system includes a spherical ball bearing 7 that slides on the ground, and a roller body 8 for accommodating and mounting the spherical ball bearing. The roller body is an inverted barrel-shaped structure with an open bottom. An annular mounting groove 9 is provided on the inner side wall of the bottom of the roller body. The spherical ball bearing is rotatably mounted in the mounting groove via a ball bearing. The bottom of the spherical ball bearing protrudes from the bottom of the roller body. The top of the roller body is fixedly connected to the base. A braking device for braking or releasing the spherical ball bearing is provided inside the upper part of the roller body. Three sets of braking devices are correspondingly provided above the three bullseye rollers. Specifically, the ball bearing includes a bowl-shaped roller sleeve 10 with openings at both the top and bottom, the upper opening diameter being smaller than the lower opening diameter. The bowl-shaped roller sleeve is a sheet metal part with a certain degree of elasticity made of stainless steel. The spherical balls can be forcibly pressed into the bowl-shaped roller sleeve during installation. The spherical balls can roll and be embedded inside the bowl-shaped roller sleeve. A number of small balls 11 are evenly distributed between the spherical balls and the inner wall of the bowl-shaped roller sleeve. The upper and lower opening edges of the bowl-shaped roller sleeve are machined with inwardly curved limiting slits to prevent the small balls from coming out of the bowl-shaped roller sleeve. The upper and lower ends of the bowl-shaped roller sleeve are respectively engaged and locked inside the mounting groove by retaining rings 11. The top and bottom of the spherical balls protrude from the upper and lower openings of the bowl-shaped roller sleeve, respectively.

[0019] Specifically, the braking device includes a braking assembly and a control assembly. The braking assembly includes an inverted bowl-shaped brake pad 12 that is adapted to the top of the spherical ball. The lower surface of the brake pad may also be provided with a friction pad (such as a leather pad or a rubber pad) to enhance friction. A telescopic rod 13 is vertically fixedly connected to the center of the top surface of the brake pad. The upper end of the telescopic rod slides through the center hole of the top plate of the roller body and is connected to a liftable limiting top cover 14. A travel space 15 is provided between the top plate of the roller body and the base for the limiting top cover to move up and down. A top pressure spring 16 is also coaxially sleeved on the outer side of the lower end of the telescopic rod. The top pressure spring can extend and press against the top surface of the brake pad and the top plate of the roller body. When the top pressure spring presses down on the brake pad, it can achieve frictional damping of the spherical ball and prevent the base from shifting when the training rod is slightly impacted.

[0020] Specifically, the control component includes a lifting rod 17 hinged above the center of the limiting top cover. The upper end of the lifting rod passes through an opening at the bottom of the base. A lever 18 is rotatably hinged to the upper end of the lifting rod. The base is a hollow, frustum-shaped structure. The outer end of the lever protrudes from the middle of a vertical elongated hole 19 on the side wall of the base. The middle fulcrum of the lever is rotatably hinged to the outer side wall of the base via a hinge seat 20. A lever handle 21 is connected to the outer end of the lever. When the lever handle is pressed down, the lifting rod can lift the brake pads and remove them from the spherical ball bearings. This ensures that when the wheel runs over the lever handle, the base can slide away from the vehicle in time, preventing the wheel from continuing to run over the base of the training rod and thus preventing the base from being crushed.

[0021] Example 2 Based on Embodiment 1, a strong magnetic ring 22 is also provided around the outer periphery of the bottom opening of the base. The strong magnetic ring is fixedly embedded in the lower surface of the base. Both the strong magnetic ring and the limiting top cover are made of strong neodymium magnets. The downward pressing force of the top spring is greater than the magnetic attraction of the strong magnetic ring to the limiting top cover. When the lifting rod drives the brake pad to a certain height, the strong magnetic ring can strongly attract the limiting top cover to ensure the reliable and continuous release of the brake pad to the ball bearing. When it is necessary to brake the chassis again, it is only necessary to lift the pry handle upward again to achieve braking again.

[0022] Specifically, the three sets of braking devices, each with a 120° arc-shaped lever, are connected end to end to form a single, movable ring that can be raised and lowered. The ring is suspended on the outer periphery of the base via the levers of the three sets of braking devices. When a wheel runs over the suspended ring, the ring will press down as a whole, forcing the three sets of braking devices to release simultaneously. This ensures reliable sliding of the base, prevents it from being run over, and protects the base.

[0023] Example 3 Based on Embodiment 2, a strong magnetic block 23 is fixedly connected to the lower end of the helical spring, and a strong magnetic sheet 24 is fixedly installed at the upper end of the lower spring seat. Both the strong magnetic block and the strong magnetic sheet are made of strong neodymium magnets. When the lower end of the helical spring is inserted into the lower spring seat, the strong magnetic sheet can strongly attract the strong magnetic block, enhancing the bonding force between the helical spring and the lower spring seat. This ensures that the lower end of the helical spring can be relatively securely inserted into the upper slot of the lower spring seat, so that the training bar will not easily tip over after a slight impact, but will only experience slight elastic swaying. At the same time, it is also necessary to ensure that when the training bar is subjected to a relatively violent impact, the magnetic attraction between the strong magnetic sheet and the strong magnetic block is insufficient to resist the large impact force, thereby ensuring that the lower end of the helical spring can smoothly disengage from the upper slot and spring away, thus protecting the bar from tipping over like a traditional fixed training bar, causing the top of the bar to hit the ground first and break.

[0024] The upper spring seat has an upper insertion port 25 and a lower insertion port 26 at its top and bottom, respectively. The lower end of the rod is fixedly inserted into the upper insertion port. The lower spring seat has an upper slot 27 and a lower slot 28 at its top and bottom, respectively. The central boss 29 integrally formed on the top of the base is fixedly inserted into the lower slot. The upper end of the helical spring is fixedly inserted into the lower insertion port of the upper spring seat, and the lower end of the helical spring is movably inserted into the upper slot of the lower spring seat. The strong magnetic sheet is fixedly embedded in the inner bottom of the upper slot. A boss 30 is integrally formed above the center of the strong magnetic block, and the boss is interference-fitted and fixedly connected to the inner side of the lower end of the helical spring.

[0025] Specifically, the upper end of the helical spring is tightly fitted with the inner wall of the lower insertion port of the upper spring seat, and a protruding plug 31 is integrally formed below the center of the lower insertion port. The outer wall of the protruding plug is tightly pressed and supported inside the helical spring. The lower end of the helical spring is loosely fitted with the inner wall of the upper slot of the lower spring seat, preferably with a clearance of 0.3 mm, so that when the training rod is subjected to a relatively violent impact, the lower end of the helical spring can be disengaged from the upper slot and ejected. The upper end of the helical spring is inserted into the lower insertion port of the upper spring seat for three pitches to ensure a secure connection between the upper end of the helical spring and the upper spring seat, and the lower end of the helical spring is inserted into the upper slot of the lower spring seat for one pitch to facilitate the smooth disengagement of the lower end of the helical spring from the upper slot.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
