Description

Technical Field

[0001] The invention relates to the field of parking and provides a modular mechanical and non-mechanical mixed parking device. Background Art

[0002] In daily life, non-motor vehicles and motor vehicles are divided into different parking ranges due to different parking devices. However, such parking devices bring many problems. On the one hand, there is an oversupply of parking spaces for non-motor vehicles, while it is common for motor vehicles to have difficulty parking. The separation of parking ranges for motor vehicles and non-motor vehicles has caused a waste of parking space and brought great inconvenience to motor vehicle owners. On the other hand, the current non-motor vehicle parking device only provides parking spaces, but cannot park non-motor vehicles one next to another in an orderly manner. Non-motor vehicles parked randomly not only occupy the parking space for motor vehicles, but also have the risk of scratching parked motor vehicles. In addition, under the trend of combining electromechanical technology, parking devices are constantly developing. For example, devices that use controllers and voice players to assist in standardizing parking. However, they cannot be applied to various outdoor environments, and compared with pure machinery, the maintenance of motor batteries is more difficult. In addition, there are also large parking lots or three-dimensional parking garages, but they are often restricted by land conditions, and such parking devices have the problem of limited scope of application. Summary of the invention

[0003] In order to solve the above problems, this patent proposes a modular motor and non-motor vehicle mixed pure mechanical parking device, which adopts a pure mechanical structure to connect various modules to achieve orderly parking of motor vehicles and non-motor vehicles. The technical solution is as follows:

[0004] A modular mechanical parking device, each module includes a wheel fixing mechanism and a logic linkage mechanism connected to two parallel support seats 11, characterized in that:

[0005] The wheel fixing mechanism comprises two groups of connecting rod mechanisms, a crankshaft 1, two large arm fixing seats 3, two large arms 4, a sliding shaft 5, two torsion springs 12, two upper bracket grooves 13 and two rollers 15; each group of connecting rod mechanisms is formed by two pairs of parallel four-links formed by rocker two 6, connecting rod one 7, rocker one 8, connecting rod two 9 and rocker three 10 being hinged by bolts, one end of each of rocker two 6 and rocker three 10 is hinged to the support seat 11, and the other end is hinged to the two ends of connecting rod two 9, one end of rocker one 8 is hinged to the support seat 11, and the other end is hinged to the connecting rod The connecting rod 1 is hinged to the connecting rod 17, and the connecting rod 17 is also hinged to the rocker 2 6, so that the movement of the connecting rod 17 is amplified to the connecting rod 2 9. The two upper bracket grooves 13 are fixed on the connecting rod 2 9 to fix the wheels. The crankshaft 1 is installed in the holes of the two support seats 11 through bearings and can rotate relative to the support seats 11. Two large arm fixing seats 3 and two torsion springs 12 are connected to the crankshaft 1. The large arm fixing seat 3 is fixedly connected to the crankshaft 1. The two ends of the torsion spring 12 are respectively fixedly connected to the support seat 11 and the large arm fixing seat 3 to provide torque for the large arm fixing seat 3 to reset. One end of the big arm 4 is fixed to the two big arm support seats 3 by bolts, and the other end is equipped with two rollers 15, which limit the non-motor vehicle wheels and convert the sliding friction into rolling friction so that the wheels can enter; the sliding shaft 5 is embedded in the slot composed of the slot 31 on the big arm fixed seat, the slot 71 on the connecting rod 1, the horizontal slot 111 of the support seat and the arc slot 112 of the support seat, wherein the slot 71 on the connecting rod 1 is parallel to the horizontal slot 111 of the support seat, and the slot 31 on the big arm fixed seat can be around the support seat. When the boom support seat 3 rotates from 0° to 90°, it drives the sliding shaft 5 to slide around the arc in the circular arc slot 112 of the support seat, thereby further driving the connecting rod 7 to move horizontally toward the upper side close to the support seat 11, thereby transmitting the movement of the boom 4 to the connecting rod 7, so that the parallel four-bar linkage is deployed; when the boom support seat 3 rotates from 90° to 120°, it drives the sliding shaft 5 to slide horizontally in the horizontal slot 111 of the support seat and the slot 71 on the connecting rod 1, but does not affect the position of the connecting rod 7.

[0006] Preferably, the logical linkage mechanism includes a crankshaft 1, two rotating shafts 2 and two connecting sleeves 14. The rotating shaft 2 is connected to the crankshaft 1. The rotating shaft 2 has a boss with a central angle of 60°, and the crankshaft 1 has a groove with a central angle of 120°. The boss on the rotating shaft 2 cooperates with the groove on the crankshaft 1 to achieve a rotational motion with a 60° angular idle stroke; the connecting sleeve 14 is fixedly connected to the rotating shaft 2 to transmit torque to the rotating shaft 2 of the next module.

DETAILED DESCRIPTION

[0020] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] The present invention will be developed from two aspects: the non-motor vehicle parking process and how the various modules are linked. The specific embodiments are as follows: Figure 6 As shown, when the non-motor vehicle is not parked, the arm 4 and the roller 15 mounted thereon are in the torsion spring 12 (see Figure 1 , Figure 2 , Figure 3 and Figure 4) is in a horizontal position. At this time, the parking device is similar in size to an ordinary speed bump and can be used for parking motor vehicles.

[0022] The parking device is mainly composed of a wheel fixing mechanism and a logic linkage mechanism. When the wheel fixing mechanism is unfolded, non-motor vehicles such as bicycles and electric vehicles can be parked, and when the wheel fixing mechanism is retracted, motor vehicles such as cars can be parked. The logic linkage mechanism can constrain the parking order of non-motor vehicles, so that non-motor vehicles can be parked in sequence to save space for parking motor vehicles.

[0023] The wheel fixing mechanism has the characteristics of a variable topology structure, and includes two groups of connecting rod mechanisms, a crankshaft 1, two large arm fixing seats 3, two large arms 4, a sliding shaft 5, two torsion springs 12, two upper bracket slots 13 and two rollers 15. Each group of connecting rod mechanisms is formed by two pairs of parallel four-links, namely, rocker 2 6, connecting rod 1 7, rocker 1 8, connecting rod 2 9 and rocker 3 10, which are hinged by bolts. One end of rocker 2 6 and rocker 3 10 is hinged to the support seat 11 and the other end is hinged to connecting rod 2 9. One end of rocker 1 8 is hinged to the support seat 11 and the other end is hinged to connecting rod 1 7. At the same time, connecting rod 1 7 is also hinged to rocker 6, so that the movement of connecting rod 1 7 is amplified to connecting rod 2 9. The two upper bracket slots 13 are fixed on connecting rod 2 9. It plays the role of fixing the wheels; the crankshaft 1 is installed in the holes of the two support seats 11 through bearings and can rotate relative to the support seats 11. Two large arm fixing seats 3 and two torsion springs 12 are installed on the crankshaft 1. The large arm fixing seat 3 is fixedly connected to the crankshaft 1. The two ends of the torsion spring 12 are respectively fixedly connected to the support seat 11 and the large arm fixing seat 3 to provide torque for the large arm fixing seat 3 to reset; one end of the two large arms 4 is fixed to the two large arm support seats 3 by bolts, and the other end is equipped with two rollers 15, which plays a limiting role on the wheel and converts the sliding friction into rolling friction so that the wheel can enter; the sliding shaft 5 is embedded in the slot composed of the slot 31 on the boom fixing seat, the slot 71 on the connecting rod one, the horizontal slot 111 of the support seat and the arc slot 112 of the support seat, wherein the slot 71 on the connecting rod one is parallel to the horizontal slot 111 of the support seat, and the slot 31 on the boom fixing seat can rotate around the center of the arc slot 112 of the support seat. When the boom support seat 3 rotates from 0° to 90°, it drives the sliding shaft 5 to slide around the arc in the arc slot 112 of the support seat, thereby further driving the connecting rod one 7 to move horizontally to the upper right, thereby transmitting the movement of the boom 4 to the connecting rod one 7, so that the parallel four-bar linkage is deployed, and when the boom support seat 3 rotates from 90° to 120°, it drives the sliding shaft 5 to slide horizontally in the horizontal slot 111 of the support seat and the slot 71 on the connecting rod one, without affecting the position of the connecting rod one 7.

[0024] The logic linkage mechanism comprises a crankshaft 1, two rotating shafts 2 and two connecting sleeves 14. The rotating shaft 2 is connected to the crankshaft 1, and the rotating shaft 2 has a convex shoulder with a central angle of 60°, and the crankshaft 1 has a groove with a central angle of 120°. The convex shoulder on the rotating shaft 2 cooperates with the groove on the crankshaft 1 to realize a rotational motion with an angular idle stroke of 60°; the connecting sleeve 14 is fixedly connected to the rotating shaft 2, and can transmit the torque to the rotating shaft 2 of the next module.

[0025] In this embodiment, if Figure 1 , Figure 4 and Figure 7 As shown, the arm 4 of the parking device is unfolded at an angle of 60°, and non-motor vehicles can be parked in this case. It is only necessary to push the wheel against the roller 15 and push it forward. During the forward movement of the wheel, the arm 4 and the arm fixing seat 3 connected thereto increase their extension angles continuously, driving the sliding shaft 5 matched with the notch 31 on the arm fixing seat to move in the arc notch 112 of the support seat. At this time, the sliding shaft 5 moves in the arc notch 112 of the support seat, driving the connecting rod 1 7 to move horizontally. The connecting rod 1 7 pulls the rocker 1 8 and the rocker 2 6 to rotate with the hinge connected to the support seat 11 as the center of the circle. The rocker 2 6 uses the lever principle and uses the hinge connected to the support seat 11 as the fulcrum to amplify the translation of the connecting rod 1 7 into the translation of the connecting rod 2 9, that is, the two-stage parallel four-bar linkage amplifies the movement, lifts the two upper bracket slots 13 fixed on the connecting rod 2 9, and provides positioning for the wheel.

[0026] In this embodiment, if Figure 2 and Figure 4 As shown, the wheels continue to move forward, and the boom 4 and the boom fixing seat 3 of the parking device continue to rotate. At this time, the sliding shaft 5 enters the horizontal slot 111 of the support seat. Thereafter, since the sliding shaft 5 only moves horizontally in the slot 71 of the connecting rod 1, the connecting rod 1 7 no longer moves. At this time, the rocker arm 2 6, the rocker arm 1 8 and the rocker arm 3 10 are all in the extreme position perpendicular to the support seat 11, no longer move, and are positioned.

[0027] In this embodiment, if Figure 3 , Figure 4 and Figure 8 As shown, the arm 4 and the arm fixing seat 3 of the parking device are unfolded to the limit position (the angle with the support seat 11 is less than or equal to 120°) under the combined action of the wheel and the torsion spring 12, completing the unfolding of the wheel fixing mechanism. At this time, the two upper bracket grooves 13 and the two rollers 15 provide fixation for the wheel. When the wheel is removed from the parking device, the above steps are reversed under the action of the torsion spring 12, so that the parking device is retracted.

[0028] In this embodiment, if Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, there is an idle stroke of 60° between the groove of the crankshaft 1 and the shoulder of the rotating shaft 2. Through this idle stroke, a purely mechanical delay logic linkage control between multiple modules can be realized. The specific implementation method is as follows: When the arm 4 of the first parking device module is manually unfolded to 60°, the module is in a parking state, that is, the non-motor vehicle can be pushed in. Since there is an idle stroke of 60° between the crankshaft 1 and the rotating shaft 2, the groove of the crankshaft 1 has just contacted the shoulder of the rotating shaft 2 at this time, and is in a state where torque can be transmitted. At this time, the module adjacent to the module is in a closed state and cannot be parked. When the wheel is fully pushed in and the arm 4 of the module is unfolded to 120°, the crankshaft 1 drives the rotating shaft 2 in contact with its groove to rotate 60°. The modules transmit the movement of the rotating shaft 2 and the crankshaft 1 to the module adjacent to the module through the connecting sleeve 14, so that the arm 4 of the module adjacent to the module is opened by 60° and is in a parking state. The transfer is carried out in this way, and only the modules beside the parked modules can be parked, so that the non-motor vehicles are parked in an orderly manner, providing space for the parking of motor vehicles.

[0029] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
