Description

Technical Field

[0001] The utility model relates to the technical field of parking barriers, in particular to a barrier for a smart parking system. Background Art

[0002] A barrier gate, also known as a vehicle blocker, is an entrance and exit management device specifically used to restrict the travel of motor vehicles on roads. It is now widely used in highway toll stations and parking lot systems to manage vehicle passages and to manage the entry and exit of vehicles.

[0003] The existing published patent CN216515299U discloses a barrier gate for a smart parking system. Through a setting in which one end of the rotating shaft is rotatably connected to the gate bar, when a vehicle hits the gate bar, it pushes the gate bar to rotate horizontally so that the gate bar can be opened horizontally to allow the vehicle to pass, reducing the impact of the vehicle on the gate bar and thus reducing damage to the gate bar.

[0004] During use of the above device, if a car loses control and hits the gate rod and drives away directly, the gate rod will rotate and reset under the drive of the torsion spring without the obstruction of the car. However, the gate rod will hit the protective cover due to inertia, which may not only cause secondary damage to the gate rod, but may also cause the gate box to vibrate due to the impact, causing its internal parts to loosen or be damaged. Utility Model Content

[0005] The purpose of the present utility model is to provide a barrier gate for a smart parking system that can slow down the resetting of a barrier rod, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a barrier gate for a smart parking system, comprising a mounting seat, a gate rod mounted on the inner side of the mounting seat, a mounting shaft passing through the interior of the gate rod, and the gate rod being rotatably connected to the mounting seat via the mounting shaft, two symmetrically distributed torsion springs being fixedly sleeved on the outer side of the mounting shaft, and also comprising a deceleration structure for decelerating the rotation and resetting of the gate rod, and two symmetrically distributed deceleration structures being mounted on the outer side of the gate rod; a friction plate for increasing the friction between the deceleration structure and the mounting seat, and two symmetrically distributed friction plates being fixedly embedded on the inner side of the mounting seat.

[0007] Preferably, the deceleration structure includes a cam movably embedded on the outer side of the gate rod, and the outer side of the cam is fixedly sleeved with a silicone sleeve, which can increase the friction between the cam and the friction plate.

[0008] Preferably, a positioning shaft is fixedly embedded inside the cam, and a limit groove is provided on the outside of the gate rod corresponding to the cam. The limit groove can limit the cam from rotating to the right, and the cam is rotatably connected to the gate rod through the positioning shaft and the limit groove.

[0009] Preferably, two symmetrically distributed coil springs are fixedly sleeved on the outer side of the positioning shaft, and the outer ends of the coil springs are fixedly connected to the gate rod, and the coil springs can drive the cam to rotate.

[0010] Preferably, the friction plate is in an arc shape, and a plurality of inclined tooth grooves equidistantly distributed around the circumference are provided on a side of the friction plate close to the deceleration structure, and the inclined tooth grooves are inclined to the right.

[0011] Preferably, the cam is in active contact with the friction plate through the silicone sleeve and the inclined tooth groove.

[0012] Preferably, a stopper is fixedly provided on the rear side of the gate rod corresponding to the inner side of the mounting seat, and a buffer pad is fixedly adhered to the side of the stopper close to the gate rod, and the buffer pad can buffer and reduce shock for the gate rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model installs a deceleration structure, and the limit groove in the deceleration structure can limit the cam from rotating to the left but not to the right. This is beneficial for the cam to contact and rub with the friction plate through the silicone pad during the process of the torsion spring driving the gate lever to rotate and reset, thereby decelerating the gate lever, and preventing the gate lever from hitting the mounting seat due to inertia, thereby preventing the gate lever from being damaged again.

[0015] 2. The utility model provides inclined teeth and grooves on the friction plate, and the silicone sleeve contacts and rubs against the friction plate through the inclined teeth and grooves, which can further increase the resistance of the cam moving on the friction plate, thereby further improving the deceleration effect of the deceleration structure.

[0021] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1 、 Figure 3 The figure shows a barrier gate for a smart parking system, which includes a mounting base 1, a gate rod 2 installed on the inner side of the mounting base 1, a mounting shaft 3 running through the inside of the gate rod 2, and the gate rod 2 is rotatably connected to the mounting base 1 through the mounting shaft 3, and two symmetrically distributed torsion springs are fixedly sleeved on the outer side of the mounting shaft 3. It also includes a deceleration structure 4 for decelerating the rotation and resetting of the gate rod 2, and two symmetrically distributed deceleration structures 4 are installed on the outer side of the gate rod 2; a friction plate 5 for increasing the friction force between the deceleration structure 4 and the mounting base 1, and two symmetrically distributed friction plates 5 are fixedly embedded on the inner side of the mounting base 1.

[0024] See also Figure 4 The deceleration structure 4 includes a cam 401 movably embedded in the outer side of the gate rod 2 , and a silicone sleeve 402 is fixedly sleeved on the outer side of the cam 401 . The silicone sleeve 402 can increase the friction between the cam 401 and the friction plate 5 .

[0025] See also Figure 2 A positioning shaft 403 is fixedly embedded inside the cam 401, and a limiting rotation groove 405 is opened on the outside of the gate lever 2 corresponding to the cam 401. The limiting rotation groove 405 can limit the cam 401 from rotating to the right, and the cam 401 is rotatably connected to the gate lever 2 through the positioning shaft 403 and the limiting rotation groove 405.

[0026] See also Figure 4 The outer side of the positioning shaft 403 is fixedly sleeved with two symmetrically distributed coil springs 404, and the outer end of the coil spring 404 is fixedly connected to the gate rod 2. The coil spring 404 can drive the cam 401 to rotate, and the friction plate 5 is in the shape of an arc.

[0027] The working principle of being able to slow down the resetting of the gate lever: when the car loses control and hits the gate lever 2, the gate lever 2 will drive the two cams 401 to rotate counterclockwise. During the counterclockwise rotation of the two cams 401, the cam 401 will rotate left while contacting with the friction plate 5, and will not generate resistance to the rotation of the gate lever 2. After the car hits the gate lever 2 and drives away directly, the gate lever 2 will rotate and reset under the drive of the torsion spring due to the lack of obstruction from the car. During the clockwise rotation and resetting process of the gate lever 2, the cam 401 will not be able to rotate to the right due to the obstruction of the limit groove 405, so the cam 401 will contact and rub with the friction plate 5 through the silicone sleeve 402, thereby slowing down the gate lever 2, which can prevent the gate lever 2 from hitting the mounting seat 1 due to inertia, thereby preventing the gate lever 2 from being damaged again.

[0028] Example 2

[0029] See also Figure 4 This embodiment further explains Example 1. A plurality of inclined tooth grooves 6 are provided on the side of the friction plate 5 close to the deceleration structure 4 and are equidistantly distributed around the circumference. The inclined tooth grooves 6 are inclined to the right, and the cam 401 is in active contact with the friction plate 5 through the silicone sleeve 402 and the inclined tooth grooves 6.

[0030] In this embodiment: when the torsion spring drives the brake lever 2 to rotate and reset, the silicone sleeve 402 contacts and rubs with the friction plate 5 through the inclined tooth groove 6, which can further increase the resistance of the cam 401 moving on the friction plate 5, thereby further improving the deceleration effect of the deceleration structure 4.

[0031] Example 3

[0032] See also Figure 2 This embodiment further illustrates other embodiments. A stopper 7 is fixedly provided on the inner side of the mounting seat 1 corresponding to the rear side of the gate rod 2. A buffer pad 8 is fixedly adhered to the side of the stopper 7 close to the gate rod 2. The buffer pad 8 can buffer and reduce shock for the gate rod 2.

[0033] In this embodiment, after the gate rod 2 is reset, the stopper 7 and the buffer pad 8 stop the gate rod 2 , thereby preventing the gate rod 2 from directly hitting the mounting seat 1 and providing buffering and shock absorption for the gate rod 2 .
