Description

Technical Field

[0001] This utility model relates to the field of barrier gate technology, specifically to a motor with a clutch. Background Technology

[0002] Barrier gates are one of the core devices for modern access control, and are widely used in parking lots, residential areas, industrial parks, toll stations and other places to achieve precise management, safety protection and efficiency improvement of vehicle or pedestrian passage.

[0003] After the barrier gate is raised or lowered, the lack of a corresponding locking function causes the gate arm to easily fall after being raised or be raised again after being lowered. At the same time, after being locked by the locking mechanism, the locking mechanism can still rotate with the gate arm, resulting in poor locking effect. Therefore, this utility model proposes a motor with a clutch that can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a motor with a clutch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a motor with a clutch, comprising a motor body and a cylindrical shell, wherein the motor body has a first shaft and a second shaft that can rotate synchronously at both ends, the first shaft is used to drive the brake lever to pivot, the second shaft is connected to a contact plate, and the cylindrical shell is connected to the motor body through a mounting assembly.

[0006] The cylinder shell is connected to an inner ring. The ring has a first step and a second step with the outer diameter decreasing sequentially from the rear end to the front end. A moving rod is movably inserted through the ring. A pad is connected to the front end of the moving rod. A friction part is connected to the pad. The rear end of the moving rod passes through the sleeve and is connected to an adjustment part.

[0007] The cylindrical shell is equipped with a spring and a coil body. The coil body is sleeved on the first step, and the spring is sleeved on the second step. The coil body can be energized or de-energized to drive the friction part to maintain a distance from the contact plate or to abut against the contact plate to form a lock.

[0008] Preferably, the mounting assembly includes a fixed plate located at the front end of the cylindrical shell and multiple sets of guide cylinders disposed on the outer wall of the motor body. The fixed plate has multiple sets of outwardly extending strips, each set of strips having a groove. The grooves are connected to the guide cylinders one by one, and the grooves are fitted with connecting parts that are screwed to the guide cylinders.

[0009] Preferably, the second step is connected to a frustum, the fixed plate is provided with a guide groove, the pad includes a guide cover, a liner and an insert connected in sequence from the rear end to the front end, the guide cover can be inserted into the frustum, the insert is movably fitted into the guide groove, the guide groove is used to restrict the rotation of the guide groove, and the spring abuts against the insert.

[0010] Preferably, the cylindrical shell has a hole for the wires of the coil to pass through.

[0011] Preferably, the friction part includes a pad and a friction disc, the friction disc having a plurality of fasteners passing through it and screwed onto the pad block.

[0012] Preferably, the distance between the friction part and the contact plate is 3-4 mm.

[0013] Preferably, the adjusting part includes a pin passing through the moving rod, the pin being connected to a rotating handle, the rotating handle being rotatable to pull the moving rod to move.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the coil is energized, it generates a magnetic attraction force that draws in the friction part, causing the pad to compress the spring. This causes the friction part to maintain a distance from the contact plate, allowing the motor body to rotate synchronously via the first and second shafts, smoothly driving the gate arm to pivot for raising or lowering the arm. When the coil is de-energized, it no longer magnetically attracts the friction part, causing the spring to push the pad outward, causing the friction part to abut against the contact plate and form a lock, thus locking the gate arm. The gate arm remains stable during raising or lowering.

[0016] The shape of the guide groove matches the shape of the insert. The guide groove restricts the rotation of the insert, so that when the friction part is locked against the contact plate, the friction part will not rotate, resulting in a good locking effect. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6

[0026] A motor with a clutch is provided:

[0027] The motor body 10 has a first shaft column 11 and a second shaft column 12 that can rotate synchronously at both ends;

[0028] The first axle 11 is used to drive the gate arm to pivot, and the gate arm pivots to raise or lower the arm to manage the passage of vehicles or pedestrians. The second axle 12 is connected to the contact plate 13. When the motor body 10 drives the gate arm to pivot, the first axle 11 and the second axle rotate synchronously.

[0029] The cylindrical shell 20 is connected to the motor body 10 via the mounting assembly 40. An annular body 21 is connected inside the cylindrical shell 20. The annular body 21 has a first step 211 and a second step 212 with the outer diameter decreasing sequentially from the rear end to the front end. A moving rod 30 is movably inserted through the annular body 21. A pad 31 is connected to the front end of the moving rod 30. A friction part 32 is connected to the pad 31. The friction part 32 is located outside the cylindrical shell 20.

[0030] The friction part 32 includes a pad 321 and a friction disc 322. The friction disc 322 is made of asbestos-based friction material, composite fiber friction material and other materials. Multiple fasteners pass through the friction disc 322. The multiple fasteners pass through the pad 321 and are screwed to the pad 31. The fasteners are preferably bolts and the like. After the fasteners are screwed to the pad 31, they are in a recessed state and will not protrude from the friction disc 322.

[0031] Furthermore, the pad 321 has multiple guide holes, and the friction disk 322 has multiple guide posts. During assembly, the multiple guide posts are inserted into the multiple guide holes respectively to position the friction disk 322, making assembly convenient.

[0032] The cylindrical shell 20 is equipped with a spring 23 and a coil body 22. The coil body 22 is fitted onto the first step 211, and the spring 23 is fitted onto the second step 212. The cylindrical shell 20 has a hole for the wire of the coil body 22 to pass through. The coil body 22 includes a sleeve and a coil wound on the sleeve. The spring 23 is located at the center of the coil body 22 and does not contact the coil body 22. The spring 23 abuts against the pad block 31.

[0033] The coil body 22 can be energized or de-energized. When the coil body 22 is energized, it generates a magnetic attraction force that attracts the friction part 32, causing the pad 31 to compress the spring 23. This causes the friction part 32 to maintain a distance of 3-4mm from the contact plate 13, allowing the motor body 10 to rotate synchronously via the first shaft 11 and the second shaft 12, thus smoothly driving the gate arm to pivot for raising or lowering the arm. When the coil body 22 is de-energized, it no longer magnetically attracts the friction part 32, causing the spring 23 to push the pad 31 outward, causing the friction part 32 to abut against the contact plate 13 to form a lock, thereby locking the gate arm and keeping it stable during raising or lowering.

[0034] The mounting assembly 40 includes a fixed plate 41 located at the front end of the cylindrical shell 20 and multiple sets of guide cylinders 42 disposed on the outer wall of the motor body 10. The fixed plate 41 is welded to the cylindrical shell 20 and has multiple sets of outwardly extending strips 411. Each set of strips 411 has a groove, which is connected to the guide cylinder 42 one by one. The groove is fitted with a connector that is screwed to the guide cylinder 42. The connector is preferably a screw. By screwing the screw into the groove and screwing it to the guide cylinder 42, the cylindrical shell 20 and the motor body 10 are stably connected.

[0035] The second step 212 is connected to a frustum 213. A guide groove 412 is provided on the fixed plate 41. The pad 31 includes a guide cover 311, a liner 312 and an insert 313 connected sequentially from the rear end to the front end. The guide cover 311 can be inserted into the frustum 213. The insert 313 is movably fitted into the guide groove 412. The spring 23 abuts against the insert 313. When the pad 31 compresses or releases the spring 23, it moves horizontally along the guide groove 412 through the insert 313. The shape of the guide groove 412 is adapted to the shape of the insert 313. The rotation of the insert 313 is restricted by the guide groove 412, so that when the friction part 32 abuts against the contact plate 13 to form a lock, the friction part 32 will not rotate, and the locking effect is good.

[0036] The rear end of the moving rod 30 extends out of the sleeve and is connected to an adjustment part 50. The adjustment part 50 includes a pin 51 that passes through the moving rod 30. The pin 51 is connected to a rotating handle 52, which can rotate to pull the moving rod 30 to move.

[0037] In the event of an external power outage, the friction part 32 and the contact plate 13 are locked together. If you want to adjust the state of the gate arm, you can rotate the rotating handle 52. After the rotating handle 52 comes into contact with the cylinder shell 20, it pulls the moving rod 30 to move. This causes the moving rod 30 to pull the pad block 31 to compress the spring 23, thereby causing the friction part 32 to disengage and come into contact with the contact plate 13. Thus, the gate arm can be manually pivoted for adjustment.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
