Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of road parking fee management, and in particular to a roller type parking space ground lock applied to an open parking space intelligent fee management system. Background Art
[0002] With the rapid growth of car ownership, the problem of parking difficulties in urban areas is very prominent. The current solution is to set up parking spaces on the roadsides and sidewalks in the central urban area, and provide temporary paid parking services by locking the cars in the parking spaces.
[0003] Most of the existing parking locks are mechanical manual. When the car enters or exits the parking space, it is necessary to get off the car and put down or prop up the parking lock's support rod, and then lock it, which is very inconvenient to use. If it is an open-air parking space and it rains, it will be even more troublesome. In addition, manual parking locks have no anti-collision function. When encountering a collision, both the car and the parking lock are easily damaged.
[0004] In view of the shortcomings and defects of the prior art, the inventor has proposed an invention patent application for a ground-embedded intelligent parking lock that is embedded below the ground, has no roadblocks, is easy to install, and can lock the vehicle chassis (application number 201911248088.8; application publication number CN110735410A). However, the following shortcomings still exist: ① It is possible to scratch the vehicle chassis; ② For vehicles with higher chassis such as off-road vehicles, the locking may be unreliable, resulting in evasion of fees, etc. Summary of the invention
[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings and to provide a new concept roller type berth ground lock.
[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a roller type berth lock, comprising a steel support frame 1, a roller 2, and a locking mechanism 3. The steel support frame 1 is a frame structure formed by welding a left main beam 11, a right main beam 12, a side beam 13, and a bottom plate 18. A roller mounting hole 16 and a push rod mounting hole 17 are drilled on the left main beam 11, and a roller mounting hole 16 is drilled on the right main beam 12. The cross section of the side beam 13 is an inverted U-shape, and a reinforcing rib plate 14 is welded therein. The space between the left main beam 11 and the reinforcing rib plate 14 is a linear motor installation interval 15, and a motor mounting seat 9 is welded therein. An end cover plate 10 is also provided on the outer side of the left main beam 11; the two ends of the roller 2 are respectively connected by deep grooves with dust covers. The ball bearing 5, the elastic retaining ring 6 for the hole, and the sealing plate 7 are installed in the roller mounting hole 16; the locking mechanism 3 includes a linear motor 31, a locking spring 32, a push rod 33, and a locking plate 34. The linear motor 31 is fixedly mounted on the motor mounting seat 9. The push rod 33 passes through the push rod mounting hole 17 and always remains concentric with the axis of the linear motor 31. The locking spring 32 is sleeved on its right end. The locking plate 34 is in the shape of a long strip, and two hexagonal holes 341 and two round holes 342 are symmetrically arranged on it. It is fixed to the left end of the push rod 33 through a locking plate nut 35 and a locking plate washer 36. The hexagonal hole 341 and the hexagonal end of the roller 2 are clearance fit, and the round hole 342 and the left end journal of the push rod 33 are transition fit; the effective stroke S of the left shift of the push rod 33 is 22mm.
[0007] As one of the preferred solutions, it also includes a floating plate 4 installed in the middle of the two rollers 2, with a cross section of an inverted U shape, and a floating plate spring 8 is arranged inside.
[0008] The present invention changes the previous contact locking method of the vehicle chassis to an idling locking method of the vehicle tires, and utilizes the locking or separation of the lock plate and two rollers in the locking mechanism to put the wheels in a moving state or an idling state, which not only prevents the car owner from evading fees, but also avoids scratches on the vehicle chassis.

DETAILED DESCRIPTION
[0021] The specific implementation methods of the present invention are further described below in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0022] like Figure 1 to Figure 3As shown, the roller type berth ground lock includes a steel support frame 1, a roller 2, and a locking mechanism 3. The steel support frame 1 is a frame structure formed by welding a left main beam 11, a right main beam 12, a side beam 13, and a bottom plate 18. A roller mounting hole 16 and a push rod mounting hole 17 are drilled on the left main beam 11, and a roller mounting hole 16 is drilled on the right main beam 12. The cross section of the side beam 13 is an inverted U-shape, and a reinforcing rib plate 14 is welded therein. The space between the left main beam 11 and the reinforcing rib plate 14 is a linear motor installation interval 15, and a motor mounting seat 9 is welded therein. An end cover plate 10 is also provided on the outer side of the left main beam 11.
[0023] Both ends of the roller 2 are respectively installed in the roller installation hole 16 through a deep groove ball bearing 5 with a dust cover, a hole elastic retaining ring 6, and a sealing plate 7.
[0024] like Figure 4-5 As shown, the locking mechanism 3 includes a linear motor 31, a locking spring 32, a push rod 33, and a locking plate 34. The linear motor 31 is fixedly mounted on the motor mounting seat 9. The push rod 33 passes through the push rod mounting hole 17 and always remains concentric with the axis of the linear motor 31. The locking spring 32 is sleeved on the right end of the push rod 33. The locking plate 34 is fixedly mounted on the left end of the push rod 33 through a locking plate nut 35 and a locking plate washer 36. The hexagonal hole 341 is clearance-fitted with the hexagonal end of the roller 2, and the round hole 342 is transition-fitted with the left end journal of the push rod 33.
[0025] like Figure 6 to Figure 8 As shown, the leftmost end of the roller 2 is hexagonal and has a clearance fit with the hexagonal hole of the locking plate 34 .
[0026] like Figure 1 As shown, in order to prevent pedestrians from falling into the gap between the rollers, a floating plate 4 is installed in the middle of the two rollers 2, and its cross section is an inverted U shape, and a floating plate spring 8 is arranged inside.
[0027] like Fig. 9 As shown, the locking plate 34 is in the shape of an elongated strip, and two hexagonal holes 341 and two circular holes 342 are symmetrically arranged thereon.
[0028] The working principle of the present invention is as follows: Figure 10-11 As shown, when the vehicle is about to enter the parking space, the linear motor shaft of the locking mechanism does not contact the push rod, the locking plate locks the roller, and the roller cannot rotate freely. When the parked vehicle enters the billing period, the linear motor of the locking mechanism is powered on and rotates forward, the motor shaft extends to the left, first contacts the push rod, and then pushes the push rod to the left, compressing the locking spring. When the effective stroke of the push rod reaches 22mm, the lock plate separates from the roller end, the roller is in a free state, and the vehicle cannot drive out. After the owner scans the code to pay, the linear motor is powered on and reversed, the motor shaft retracts to the right, and the push rod returns the lock plate to lock the roller under the reaction force of the locking spring, and the vehicle can leave the parking space.
[0029] The present invention is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose and principle of the present invention.
