[0002] With the continuous growth of the number of cars, the traffic accident rate is also rising. In order to reduce the accident rate, people have developed speed bumps. The emergence of speed bumps has greatly reduced the occurrence of traffic accidents, but speed bumps have their pros and cons. Speed ​​bumps cause driving comfort to deteriorate, because no matter how fast or slow the car is, there will be a noticeable bump when passing through the speed bump, and the damage to the vehicle is relatively large, such as the suspension system: when the vehicle passes through the speed bump, the suspension system will be impacted, which will be several times or even dozens of times higher than normal driving. Seriously affect the service life of components such as shock absorbers, springs and brackets. The existing speed bumps are simply a piece of rubber or cast steel, usually 50mm high. The speed bumps are directly punched and fixed on the road surface. No matter how fast or slow the car is, it will produce a noticeable bump. After the rubber speed bumps are crushed, the bolts remaining on the road surface will also cause secondary damage to the tires of the moving vehicle.

[0015] Compared with the prior art, the present invention has achieved the following technical effects:

[0016] The first is a support frame buried below the ground, an exposed shell movably arranged on the support frame in a vertical direction, a pressure block moving vertically with the exposed shell is connected to the bottom of the exposed shell, a limiting bin extending in the driving direction is fixed in the support frame, a ball rolling in the extending direction is arranged in the limiting bin, a first opening is opened on the top of the limiting bin for the ball to be exposed and supported at the bottom of the pressure block, the pressure block can move into the first opening after the ball moves away from the first opening, the exposed shell includes a slope located on the oncoming vehicle side, a touch plate is hinged on the slope surface for the wheel to press down and can be reset and lifted, the touch plate is connected to a connecting rod moving with it and moving the ball, a reset spring is arranged in the support frame for supporting the exposed shell to be exposed to the ground when it is lifted and reset, and a limiting part is also arranged for limiting the exposed shell when it is pressed down and making it flush with the ground, A contact plate is hinged on the slope of the exposed shell. After the tire moves to the slope of the exposed shell, it is pressed on the touch plate, so that the touch plate drives the connecting rod to swing. A limit bin is set in the support frame, and the ball moves along the limit bin under the manipulation of the connecting rod. When the vehicle passes through the speed bump quickly, the ball is either stationary or manipulated by the connecting rod and is at the bottom of the pressure block to support the pressure block, so that the exposed shell remains protruding from the ground, and the vehicle will pass through bumpy. When the vehicle passes through the speed bump slowly, the ball is manipulated by the manipulation rod to move to one side of the first opening, so that the ball does not support the pressure block, and the exposed shell moves under the pressure of the vehicle, and the pressure block moves down to the first opening with the exposed shell. At this time, the exposed shell is flush with the ground, and the vehicle passes smoothly. The entire device can guide the vehicle to pass slowly, which is more intelligent and user-friendly.

[0017] Second, the limit bin extends along the driving direction, and the limit bin gradually tilts upward along the driving direction. The connecting rod is located at the rear side of the limit bin and the pressure block along the driving direction, and a second opening is provided on the limit bin for the connecting rod to extend into and move the ball. Through the inclined setting of the limit bin, when the exposed shell is lifted and reset, the ball moves along the limit bin toward its lower end due to its own gravity, so that the ball is reset. At this time, the ball is supported on the bottom of the pressure block or moves to one side of the pressure block, so that when the subsequent car passes through the speed bump, the touch plate can move the ball again through the connecting rod, so that the exposed shell remains above the ground, or moves down to a state flush with the ground.

[0018] Third, the limiting bin extends from the bottom of the pressure block toward the side of the pressure block away from the connecting rod. Then, in actual use, the ball is initially located at the position of the pressure block corresponding to the limiting bin, that is, the first opening is correspondingly opened at the lower end of the limiting bin, so that the initial position of the ball is at the bottom of the supporting pressure block. When the vehicle speed is fast, before the connecting rod has time to move the ball, the wheel has been pressed on the top surface of the exposed shell, and the pressure block is pressed on the ball, so that the exposed shell remains protruding from the ground, and the wheel is impacted by the exposed shell, and the entire vehicle has a noticeable bumpy feeling. When the vehicle speed is slow, the wheel is pressed on the touch plate. At this time, the wheel is not moving and is pressed on the top surface of the exposed shell. The touch plate swings and drives the connecting rod to move the ball, so that the ball no longer supports the pressure block. The wheel continues to move and presses down on the exposed shell, so that the pressure block extends into the first opening, and the exposed shell gradually becomes flush with the ground. The vehicle can pass through the exposed shell relatively smoothly without any greater bumpy feeling.

[0019] Fourth, the limit bin is extended on the side of the pressure block close to the connecting rod, and a gap is provided on the top of the limit bin for the connecting rod to move, the width of the gap is smaller than the diameter of the ball, and the first opening is located at the top of the upper end of the limit bin, and the distance from the lower end of the limit bin to the first opening is greater than the distance the connecting rod moves along the limit bin. In actual use, the ball is initially located at a position of the limit bin away from the pressure block, that is, the first opening corresponds to the upper end of the limit bin, so that the initial position of the ball does not support the pressure block. When the vehicle speed is fast, the wheel quickly presses the touch plate, causing the touch plate to swing rapidly with the connecting rod, thereby forming a knocking action on the ball. The initial kinetic energy of the ball is large, and the ball moves quickly. When moving to the first opening, the wheel presses down the exposed shell, and the pressure block moves down and presses on the rolling ball, so that the exposed shell remains protruding from the ground, causing impact on the wheel, and the vehicle has a noticeable bumpy feeling. When the vehicle speed is slow, the wheel presses the touch plate, and the touch plate drives the connecting rod to swing relatively slowly, thereby moving the rolling ball along the limit bin. Since the distance from the lower end of the limit bin to the first opening is greater than the distance the connecting rod moves along the limit bin, the rolling ball does not reach the first opening due to the action of the connecting rod. Then, after the wheel is pressed on the exposed shell, the pressure block moves down and extends into the first opening, and the exposed shell is flush with the ground. The vehicle can pass through the exposed shell relatively smoothly without any greater bumpy feeling. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a mechanical speed bump device to solve the problems existing in the above-mentioned prior art. When the vehicle is traveling fast, the rolling ball is located at the first opening and supported on the bottom of the pressure block, so that the exposed shell protrudes from the ground and the vehicle will pass through bumpily. When the vehicle is traveling slowly, the rolling ball moves away from the first opening, the wheel presses down the exposed shell, the pressure block moves down with the exposed shell and extends into the first opening, the exposed shell will drop to be flush with the road surface, and the vehicle will pass smoothly, so as to guide the vehicle to pass slowly, making the speed bump more intelligent and humane.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1 to 4The present embodiment provides a mechanical speed bump device, comprising a support frame buried below the ground, an exposed shell 8 movably arranged on the support frame in a vertical direction, the exposed shell 8 preferably comprises a top surface and slopes connected to both sides of the top surface along the driving direction, a pressure block 5 moving vertically with the exposed shell 8 is connected to the bottom of the exposed shell 8, a limiting bin 7 extending in the driving direction is fixed in the support frame, a ball 3 rolling along its extension direction is arranged in the limiting bin 7, a first opening is opened at the top of the limiting bin 7 for the ball 3 to be exposed and supported at the bottom of the pressure block 5, the pressure block 5 can move into the first opening after the ball 3 moves away from the first opening, the exposed shell 8 comprises a slope located on the side of the oncoming vehicle, a touch plate 1 is hinged on the slope for the wheel to press down and can be reset and lifted, preferably a rotating shaft is arranged between the touch plate 1 and the slope, a reset torsion spring is sleeved on the rotating shaft, the touch plate 1 is connected to a connecting rod 2 moving with it and moving the ball 3, a support is arranged in the support frame to support the exposed shell 8 to be exposed to the ground when it is lifted and reset The return spring 4 is also provided with a limiting part which limits the exposed shell 8 when it is pressed down and makes it flush with the ground. Since the exposed shell 8 is hinged on the slope surface of the exposed shell 8 and the touch plate 1 is pressed on the slope surface of the exposed shell 8 after the tire moves to the exposed shell 8, so that the touch plate 1 drives the connecting rod 2 to swing. A limiting bin 7 is arranged in the supporting frame, and the rolling ball 3 moves along the limiting bin 7 under the manipulation of the connecting rod 2. When the vehicle passes through the speed bump quickly, the rolling ball 3 is either stationary or manipulated by the connecting rod 2 and is at the bottom of the pressure block 5 to support the pressure block 5 so that the exposed shell 8 remains protruding from the ground, and the vehicle will pass through bumpy. When the vehicle passes through the speed bump slowly, the rolling ball 3 is manipulated by the manipulation rod to move to one side of the first opening, so that the rolling ball 3 does not support the pressure block 5, and the exposed shell 8 moves under the manipulation of the vehicle, and the pressure block 5 moves down to the first opening with the exposed shell 8. At this time, the exposed shell 8 is flush with the ground, and the vehicle passes smoothly. The entire device can guide the vehicle to pass slowly, which is more intelligent and humane. The preferred rolling ball 3 is a solid pressure-resistant ball, preferably a steel part, etc., with a diameter of 60 mm, and the limiting bin 7 is a channel with an inner diameter of 60 mm.

[0030] Among them, the limit bin 7 extends along the driving direction, and the limit bin 7 gradually tilts upward along the driving direction, the connecting rod 2 is located at the rear side of the limit bin 7 and the pressure block 5 along the driving direction, and the limit bin 7 is provided with a second opening for the connecting rod 2 to extend into and move the ball 3. Through the inclined setting of the limit bin 7, when the exposed shell 8 is lifted and reset, the ball 3 moves along the limit bin 7 toward its lower end under the influence of its own gravity, so that the ball 3 is reset. At this time, the ball 3 is supported at the bottom of the pressure block 5 or moves to one side of the pressure block 5, which is convenient for the subsequent car to pass through the speed bump. The touch panel 1 moves the ball 3 again through the connecting rod 2, so that the exposed shell 8 is kept above the ground, or moved down to a state flush with the ground. Alternatively, as a preferred limit bin 7, it can also extend horizontally, and the ball 3 is connected to one end of the limit bin 7 with a spring to reset it, and the ball 3 is kept in the corresponding position in the limit bin 7 by the elastic force of the spring.

[0031] like Figure 1 to Figure 2 As shown in the figure, as a preferred embodiment of the present invention, the limiting bin 7 extends from the bottom of the pressure block 5 toward the side of the pressure block 5 away from the connecting rod 2. Then, in actual use, the ball 3 is initially located at the position of the limiting bin 7 corresponding to the pressure block 5, that is, the first opening is correspondingly opened at the lower end of the limiting bin 7, so that the initial position of the ball 3 is at the bottom of the supporting pressure block 5. When the vehicle speed is fast, before the connecting rod 2 has time to move the ball 3, the wheel has been pressed on the top surface of the exposed shell 8, and the pressure block 5 is pressed on the ball 3, so that the exposed shell 8 remains protruding from the ground, the wheels are impacted by the exposed shell 8, and the entire vehicle has a noticeable bumpy feeling. When the vehicle speed is slow, the wheels are pressed on the touch plate 1. At this time, the wheels are not moving and are pressed on the top surface of the exposed shell 8. The touch plate 1 swings and drives the connecting rod 2 to move the ball 3, so that the ball 3 no longer supports the pressure block 5. The wheels continue to move and press down on the exposed shell 8, so that the pressure block 5 extends into the first opening, and the exposed shell 8 is gradually flush with the ground. The vehicle can pass through the exposed shell 8 relatively smoothly without a large bumpy feeling.

[0032] like Figure 3 to Figure 4As shown, as another preferred embodiment of the present invention, the limiting bin 7 is extended to the side of the pressure block 5 close to the connecting rod 2, and a gap is provided on the top of the limiting bin 7 for the connecting rod 2 to move, the width of the gap is smaller than the diameter of the ball 3, and the first opening is located at the top of the upper end of the limiting bin 7, and the distance from the lower end of the limiting bin 7 to the first opening is greater than the distance the connecting rod 2 moves along the limiting bin 7. Then, in actual use, the ball 3 is initially located at the position of the limiting bin 7 away from the pressure block 5, that is, the first opening corresponds to the upper end of the limiting bin 7, so that the initial position of the ball 3 does not support the pressure block 5. When the vehicle speed is fast, the wheel quickly presses the touch plate 1, so that the touch plate 1 and the connecting rod 2 swing rapidly, forming a knocking action on the ball 3, and the ball 3 The initial kinetic energy is large. When it moves quickly to the first opening, the wheel presses down the exposed shell 8, and the pressure block 5 moves down and presses on the ball 3, so that the exposed shell 8 remains protruding from the ground, causing impact on the wheel, and the vehicle has a significant bumpy feeling. When the vehicle speed is slow, the wheel presses the touch plate 1, and the touch plate 1 drives the connecting rod 2 to swing relatively slowly, and then moves the ball 3 along the limit bin 7. Since the distance from the lower end of the limit bin 7 to the first opening is greater than the distance the connecting rod 2 moves along the limit bin 7, the ball 3 does not reach the first opening under the action of the connecting rod 2. Then, after the wheel is pressed on the exposed shell 8, the pressure block 5 moves down and extends into the first opening, and the exposed shell 8 is flush with the ground. The vehicle can pass through the exposed shell 8 relatively smoothly without any greater bumpy feeling.

[0033] Moreover, the pressure block 5 is located at the middle position of the exposed shell 8. When the exposed shell 8 moves downward, after the pressure block 5 is pressed on the rolling ball 3, the rolling ball 3 exerts a reaction force on the exposed shell 8 at the middle position of the exposed shell 8, thereby ensuring the stability of the exposed shell 8 and reducing the deflection force on the guide assembly. Preferably, the support frame includes side plates arranged along the circumferential direction. When the exposed shell 8 protrudes above the ground, there is a moving gap 6 between the outer peripheral edge of the exposed shell 8 and the top of the side plate for the exposed shell 8 to move. When the exposed shell 8 moves downward, it moves along the moving gap 6 to overlap the top of the side plate. The side plate and the rolling ball 3 jointly complete the support function of the exposed shell 8.

[0034] Furthermore, the bottom of the pressure block 5 is provided with a groove that is compatible with the top structure of the ball 3. The groove is buckled on the top of the ball 3 to ensure the close contact between the pressure block 5 and the ball 3, and to avoid the bottom of the pressure block 5 being relatively flat or relatively smooth, which may easily cause the ball 3 to slide away when the pressure block 5 contacts the ball 3, resulting in the pressure block 5 no longer being supported, causing the state of keeping the exposed shell 8 protruding from the ground to fail.

[0035] Preferably, the support frame includes a base plate for installing a reset spring 4, and a support plate 9 for supporting the limit bin 7 is also provided on the base plate, thereby increasing the supporting capacity of the limit bin 7, ensuring that the pressure block 5 is pressed on the rolling ball 3, and transmitting force to the limit bin 7 and the support plate 9, and then transmitting force to the base plate of the support frame, avoiding the formation of shear force on the limit bin 7, which may easily cause damage to the limit bin 7. Preferably, two support plates 9 are provided, and are symmetrically connected on both sides of the limit bin 7.

[0036] Among them, a number of guide components for the vertical movement of the exposed shell 8 are arranged between the bottom plate and the exposed shell 8, the guide components include a guide frame 10 and a slide groove arranged on the guide frame 10, the slide groove extends in the vertical direction, a fixed frame 11 is movably inserted in the slide groove along the vertical direction, a number of pulleys 12 are arranged on the fixed frame 11 at intervals along the vertical direction, the pulley 12 slides along the slide groove with the fixed frame 11, the fixed frame 11 is inserted in the slide groove, the pulley 12 slides along the extension direction of the slide groove to limit the movement of the fixed frame 11 in the vertical direction, thereby ensuring the vertical movement limit of the exposed shell 8 to avoid displacement.

[0037] Furthermore, the limiting portion is a block structure, which is fixed at the end of the slide groove away from the fixed frame 11. When the fixed frame 11 abuts against the block structure, the exposed shell 8 is flush with the ground. During the downward movement of the exposed shell 8, the fixed frame 11 and the pulley 12 are driven downward until they move to contact the block structure. At this time, the top of the exposed shell 8 is flush with the ground and maintains this state, ensuring that the vehicle passes through the speed bump smoothly.

[0038] As a preferred embodiment of the present invention, each guide assembly is divided into a first guide assembly and a second guide assembly, and the axes of the pulleys 12 on the first guide assembly and the second guide assembly are perpendicular to each other. By setting up two guide assemblies, the axes of the pulleys 12 of the two guide assemblies are perpendicular to each other, thereby ensuring horizontal limitation of the fixed frame 11 in two directions, avoiding that the axes of the pulleys 12 of the guide assemblies all extend in the same direction, and failing to ensure limitation of the pulley 12 and the fixed frame 11 in a direction perpendicular to the axis, which easily causes the fixed frame 11 and the pulley 12 to deviate in a direction perpendicular to the axis, thereby affecting the installation position of the exposed shell 8.

[0039] Adaptive changes made according to actual needs are all within the protection scope of the present invention.

[0040] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
