Description

Technical Field

[0001] The present application belongs to the field of parking locks, and in particular to a hydraulically driven automatic mechanical parking lock device. Background Art

[0002] As an important equipment in parking lots, parking locks are designed to protect the exclusive parking rights of car owners by locking parking spaces. In the current market, mechanical manual parking locks occupy a large share. However, their operation process is cumbersome and requires car owners to get off the car and manually prop up or put down the props and lock them, which is especially inconvenient in bad weather such as rainy days. Although there are remote-controlled electric lifting parking locks that solve the problem of getting off the car to open and close the locks through remote control operation, this type of parking lock relies on batteries for power supply, and the automatic discharge characteristics of the battery lead to the need for frequent charging, which further increases the inconvenience of use. In particular, when the battery needs to be removed from the parking lock and taken indoors for charging, the convenience of the parking lock is further reduced. It can be seen that the existing technology needs to be further improved and enhanced. Summary of the invention

[0003] The invention provides a hydraulically driven automatic mechanical parking lock device, which improves the convenience of using the parking lock and the service life of the parking lock, and solves the problem of frequent charging and the problem of opening and closing the lock when getting off the vehicle.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A hydraulically driven automatic mechanical parking lock device comprises an identification module, an oil transmission module and a blocking module;

[0006] The identification module includes a hydraulic oil circuit and an on-off unit capable of switching it on and off. The authorized vehicle is equipped with a trigger. When the authorized vehicle arrives at the parking area, the trigger can drive the on-off unit to operate through a physical mechanism to connect the hydraulic oil circuit. When an unfamiliar vehicle arrives at the parking area, the on-off unit keeps the hydraulic oil circuit disconnected.

[0007] The oil transfer module is capable of delivering the internally stored oil to the hydraulic oil circuit when the vehicle pressure acts on it;

[0008] The blocking module consists of a hydraulic cylinder and a blocking element. When the oil flows through the hydraulic oil circuit and enters the hydraulic cylinder, it will drive the blocking element from the blocking state to the release state, thereby freeing up the parking area for authorized vehicles. After the vehicle leaves, the blocking element can switch from the release state back to the blocking state to automatically lock; when the oil cannot enter the hydraulic cylinder through the hydraulic oil circuit, the blocking element maintains the blocking state unchanged to prevent unfamiliar vehicles from parking.

[0009] By adopting the above-mentioned hydraulically driven automatic mechanical parking lock, electricity is abandoned as a power source, thereby avoiding the problem of parking lock failure caused by power failure or power outage, reducing the investment and maintenance costs of power facilities, and also avoiding the inconvenience caused by frequent charging. It adopts a purely mechanical design, has good waterproof and moisture-proof properties, and can operate stably for a long time in harsh outdoor environments. Through the physical interaction between the trigger and the on-off unit, the on-off control of the hydraulic oil circuit is realized, ensuring that only authorized vehicles can unlock and park, effectively preventing the parking space from being occupied or stolen, and the oil in the hydraulic system can be recycled, reducing oil loss and replacement costs, and further extending the service life of the device.

[0013] In a preferred implementation, the pushing block is protruding from the rear of the vehicle / the pushing block and the blocking element on the upper side of the A-type sliding block are both magnetic and have the same polarity, and the pushing block is built into the rear of the vehicle.

[0014] In a preferred implementation, a reset spring is provided between the end of the on / off unit and the track to achieve position reset.

[0018] In a preferred implementation, the oil return pipeline is provided with a one-way valve to allow the oil in the hydraulic cylinder to return to the cylinder through the oil return pipeline, while preventing the oil in the cylinder from flowing back into the hydraulic cylinder through the oil return pipeline.

[0043] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0044] The present invention will be described below in conjunction with the accompanying drawings.

[0045] The specific plans adopted are:

[0046] like Figure 1-15 As shown, the present invention provides a hydraulically driven automatic mechanical parking lock device, including an identification module, an oil transmission module and a blocking module;

[0047] The identification module includes a hydraulic oil circuit 10 and an on-off unit 11 capable of switching it on and off. The authorized vehicle is equipped with a trigger 4. When the authorized vehicle arrives at the parking area, the trigger can drive the on-off unit to operate through a physical mechanism to connect the hydraulic oil circuit, or when an unfamiliar vehicle arrives at the parking area, the on-off unit keeps the hydraulic oil circuit disconnected;

[0048] The oil transfer module is capable of delivering the internally stored oil to the hydraulic oil circuit when the vehicle pressure acts on it;

[0049] The blocking module consists of a hydraulic cylinder 30 and a blocking element 3. When the oil flows through the hydraulic oil circuit 10 and enters the hydraulic cylinder, it drives the blocking element 3 from the blocking state to the release state, thereby freeing up the parking area for authorized vehicles. After the vehicle leaves, the blocking element can switch from the release state back to the blocking state to automatically lock; when the oil cannot enter the hydraulic cylinder through the hydraulic oil circuit, the blocking element maintains the blocking state unchanged to prevent unfamiliar vehicles from parking.

[0050] The above structure does not rely on electric drive, avoiding the energy consumption and environmental pollution problems caused by frequent charging of traditional electric parking locks; reducing the maintenance cost and time caused by circuit failure, and improving the reliability and stability of the device. The hydraulic drive system is known for its high stability and durability, and can withstand the influence of severe weather and environment, extending the service life of the device. The oil in the oil transmission module is circulated inside the device, reducing the frequency of replacement due to oil loss, and further improving the durability of the device. Through the hydraulic oil circuit on-off unit in the identification module and the trigger configured for the authorized vehicle, the device can identify authorized vehicles and unfamiliar vehicles. When the authorized vehicle arrives at the parking area, the trigger drives the on-off unit through a physical mechanism to connect the hydraulic oil circuit, thereby realizing automatic unlocking; while unfamiliar vehicles cannot trigger this mechanism, keeping the hydraulic oil circuit disconnected, effectively preventing illegal occupation of parking spaces, without manual intervention, and improving parking efficiency.

[0051] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 The identification module is embedded with a guide rail system. The guide rail 12 is precisely equipped with a switch unit. A reset spring 13 is provided between the end of the switch unit and the rail to achieve position reset. It has a through groove 111 structure that runs through the entire structure. When the authorized vehicle arrives at the preset parking area, the trigger configured therein can push the switch unit to move smoothly along the guide rail in a physical interactive manner, thereby adjusting the position of the switch unit so that the through groove inside it can be docked with the hydraulic oil circuit, thereby establishing a path for the oil to flow, allowing the authorized vehicle to be parked smoothly in the designated parking space. The mechanical transmission and logic control principles are integrated to ensure the automatic unlocking function of the parking lock after the authorized vehicle is identified.

[0052] See also Fig.10 , Fig.11 and Fig.12The oil transmission module is mainly composed of an oil cylinder 2, a support rod 20, a pressure plate, a load-bearing plate 21, an elastic element 22 and connecting pipelines. Among them, the oil cylinder is responsible for containing hydraulic oil and serves as a core component for pressure transmission. One end of the support rod 20 is connected to a pressure plate that matches the diameter of the oil cylinder 2, and the pressure plate is located inside the oil cylinder; and the other end of the support rod 20 is connected to the load-bearing plate. Between the load-bearing plate and the cylinder head of the oil cylinder, an elastic element 22 is provided to provide buffering and resetting effects. When the load-bearing plate 21 is subjected to external pressure, it will transfer the pressure to the pressure plate through the support rod, thereby pushing the oil in the oil cylinder. At this time, the oil cylinder is connected to the hydraulic oil circuit through a pre-set pipeline, so that the pushed oil can smoothly enter the hydraulic oil circuit.

[0053] See also Figure 1 , Figure 2 and Figure 3 The pipeline includes an oil inlet pipeline and an oil return pipeline. The oil inlet pipeline includes an oil inlet main pipe 23 and an oil inlet branch pipe 24. The oil return pipeline includes an oil return main pipe 25 and an oil return branch pipe 26. The oil inlet main pipe includes two sections. One end of the first oil inlet main pipe is connected to the oil cylinder, and the other end is connected to the inlet of the hydraulic oil circuit. The outlet of the hydraulic oil circuit is connected to the second oil inlet main pipe. The second oil inlet main pipe is connected to multiple oil inlet branches, and the multiple oil inlet branches can be connected to multiple hydraulic cylinders 30 respectively; multiple hydraulic cylinders are respectively connected to multiple oil return branches 26, and multiple oil return branches 26 are connected to one oil return main pipe 25. The oil return main pipe is connected to the oil cylinder 2. The oil cylinder is provided with two pipeline connecting ports, and the two connecting ports are both arranged near the bottom of the oil cylinder. The oil return pipeline is provided with a one-way valve 27 to enable the oil in the hydraulic cylinder to return to the oil cylinder through the oil return pipeline, while preventing the oil in the oil cylinder from flowing back into the hydraulic cylinder through the oil return pipeline.

[0054] See also Figure 8 and Fig. 9 The blocking element includes a first blocking rod 31 and a second blocking rod 32 which are hinged to each other. The free end of the first blocking rod is hinged to a C-type slider 33. The C-type slider is arranged on a slide rail 34 and is connected to the piston rod of the hydraulic cylinder 30. A spring 35 is arranged between the C-type slider and the slide rail. The free end of the second blocking rod is hinged to the tail of the hydraulic cylinder.

[0055] When the piston rod of the hydraulic cylinder extends, it pushes the C-type slider 33 to move along the slide rail 34. Since the C-type slider is hinged to the free end of the first blocking rod, the movement of the C-type slider will drive the first blocking rod 31 to rotate. At the same time, since the second blocking rod 32 is hinged to the first blocking rod 31 and its free end is hinged to the tail of the hydraulic cylinder, the rotation of the first blocking rod will also drive the second blocking rod to rotate. In this state, the highest points of the first blocking rod and the second blocking rod will be lower than the height of the vehicle chassis, thereby allowing the vehicle to pass and be released.

[0056] When the vehicle leaves, the C-type slider will return to its original position along the slide rail under the action of the spring 35 (or other reset mechanism), causing the hydraulic rod to retract back into the hydraulic cylinder. At this time, the first blocking rod 31 and the second blocking rod 32 will return to their initial blocking positions under the action of the hinge point. In this state, the highest points of the first blocking rod and the second blocking rod will be higher than the height of the vehicle chassis, thereby preventing the vehicle from parking.

[0057] The specific implementation of the trigger on the vehicle may be one of the following embodiments:

[0058] Example 1, see Fig.15 An electromagnet is installed at the bottom of the vehicle as a trigger 4, which is connected to the vehicle's power system so that its magnetic function can be activated when needed. At the same time, the switch unit is designed as an iron block, which is cleverly placed inside the guide rail 12 to respond to external magnetic force.

[0059] Under normal conditions, the electromagnet at the bottom of the vehicle remains powered off and does not generate magnetic force, so it will not affect daily driving. When the vehicle is ready to park at the parking position, the electromagnet is activated by the user and quickly generates a strong suction force. This magnetic force acts on the iron on-off unit 11, driving it to slide smoothly along the guide rail. As the iron block moves, the through groove inside it gradually aligns with and penetrates the hydraulic oil circuit, thereby establishing a channel for the flow of oil, so that the blocking element switches from the blocking state to the release state, allowing the vehicle to be parked smoothly at the designated position.

[0060] In this embodiment, the electromagnet can be arranged on the bottom surface of the rear of the vehicle, located behind the rear wheel of the vehicle, and the oil cylinder 2, the base 1, and the blocking element 3 are arranged in sequence along the length direction of the parking area. For example, if the blocking element is arranged in the middle of the parking area, then the base with the slider is arranged in the middle front position, and the oil transmission module is arranged in front of the base 1, and its bearing plate extends all the way to the rear of the parking area.

[0061] Specifically, when the authorized vehicle is ready to park, first, the electromagnet will be energized to drive the slider to move, thereby opening the hydraulic oil circuit 10. Subsequently, the rear wheels of the vehicle will press on the load-bearing plate 21. This action causes the hydraulic oil to pass through a series of pipes - first the first section of the oil inlet main pipe, then enter the hydraulic oil circuit, then pass through the second section of the oil inlet main pipe and the oil inlet branch pipe, and finally flow into the hydraulic cylinder. In this process, the blocking element in the hydraulic cylinder will be triggered, starting the release mechanism. At the same time, another part of the hydraulic oil will be directed to the return oil branch pipe and the return oil main pipe, but will be blocked by the one-way valve and cannot enter the hydraulic cylinder.

[0062] As the vehicle continues to park backward, the rear wheels will continue to press the load-bearing plate 21 to keep the pressure in the oil return line stable. During the movement of the vehicle, the distance between the electromagnet and the slider will gradually increase until the interaction force is lost. At this time, the slider will return to the initial position under the action of the return spring, and the hydraulic oil circuit 10 will also be disconnected. Since the oil in the hydraulic cylinder has no discharge path at this time, the blocking element will maintain the release posture.

[0063] When the vehicle leaves, the load-bearing plate will rise under the action of the elastic element, and the space in the hydraulic cylinder will gradually increase. At this time, the oil in the return oil pipeline can flow back into the cylinder, and the piston rod of the hydraulic cylinder will also shrink back into the cylinder under the action of the spring. In this way, the oil in the hydraulic cylinder can flow back to the cylinder through the return oil branch pipe and the return oil main pipe, and return to the initial blocking state.

[0064] The car owner does not need to get out of the car to manually operate the parking lock. He only needs to drive the vehicle close to it and activate the electromagnet to automatically complete the unlocking process, which greatly improves the convenience of parking. Since the unlocking process depends on the power supply and magnetic attraction of the electromagnet, unauthorized vehicles cannot trigger the unlocking mechanism, effectively preventing misoperation or illegal occupation of parking spaces. The electromagnet is usually powered off and does not consume energy. It is powered on and activated when parking, and only uses electricity for a short time, realizing the effective use of energy. The contactless physical mechanism means that there will be no physical collision between the authorized vehicle and the parking lock, thereby avoiding damage to the vehicle or parking lock caused by collision.

[0065] Example 2, see Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.13 and Fig.14 A push block is set as a trigger at the rear of the vehicle, and three guide rails are configured. The on-off unit consists of two types of sliders: A-type slider 110 and B-type slider 112, which have different positions of through slots 111. Specifically, the middle is the B-type slider, and the two sides are the A-type sliders.

[0066] Figure 5 The relative position of the slider and the hydraulic oil circuit is shown in the state without a vehicle. In this state, the left, middle and right sliders are in a flush posture. At this time, the through grooves of the A-type sliders on both sides are not connected to the hydraulic oil circuit, while the through grooves of the B-type slider in the middle are connected to the hydraulic oil circuit.

[0067] When an authorized vehicle comes to the parking area (such as Figure 6As shown in the figure, the push block at the rear of the vehicle pushes the two A-type sliders closer to the edge of the base, while the middle B-type slider remains in place. In this state, the through slots of the left, middle and right sliders are connected to the hydraulic oil circuit, allowing the hydraulic oil to flow. It is worth noting that the length of the push block is designed to match the relative distance between the A-type slider from the initial position to the conduction position to ensure that the slider movement can be accurately triggered.

[0068] However, when an unfamiliar vehicle arrives at the parking area (e.g. Figure 7 As shown in the figure, the rear of the vehicle will push the left, middle and right sliders at the same time to keep them flush. In this state, although the through grooves of the A-type sliders on both sides are connected to the hydraulic oil circuit, the through groove of the middle B-type slider is staggered from the hydraulic oil circuit, causing the entire hydraulic oil circuit to be disconnected.

[0069] See also Figure 8 , the blocking element is mounted on the upper side of the slider. In the optimized solution, the push block is designed to protrude from the rear of the vehicle so that when the vehicle is authorized to park, the push block can contact the blocking elements on the left and right A-type sliders. This contact will cause the A-type slider 110 to move. When the slider moves to a certain distance (such as Figure 6 As shown in the figure, the hydraulic oil circuit 10 will be opened. Subsequently, the oil in the oil cylinder 2 will be transported to the three hydraulic cylinders through the first section of the oil inlet main pipe, the hydraulic oil circuit, the second section of the oil inlet main pipe and the oil inlet branch pipe, thereby triggering the release mechanism of the blocking element. At the same time, another part of the oil will be transported to the oil return branch pipe and the oil return main pipe, but will be intercepted by the one-way valve and cannot enter the hydraulic cylinder. This process will cause the blocking element to change from the blocking state to the release state, allowing the vehicle to continue to enter the parking area.

[0070] In order to reduce the influence of the pressure that may be generated between the blocking element and the push block on the action of the blocking element, the two are designed to have less friction. Specifically, they can use materials with low friction coefficients, such as polytetrafluoroethylene (PTFE) or nylon, to reduce friction.

[0071] In addition, the oil cylinder 2 is located in front of the base, but the load-bearing plate extends to the parking area behind the base. When the vehicle is parked in place, its weight will always be pressed on the load-bearing plate, thereby maintaining pressure on the support rod. When the vehicle leaves, the load-bearing plate will rise under the action of the elastic element, so that the space in the oil cylinder will gradually increase. At this time, the oil in the return oil pipeline can flow back into the oil cylinder, and the piston rod of the hydraulic cylinder will also shrink back into the cylinder under the action of the spring. In this way, the oil in the hydraulic cylinder can flow back into the oil cylinder through the return oil branch pipe and the return oil main pipe, so that the hydraulic cylinder returns to the blocked state.

[0072] In a second feasible embodiment, the push block and the blocking element on the upper side of the A-type slider 110 are both endowed with magnetism, and their polarities are the same. The push block is cleverly built into the rear of the vehicle so that it does not exceed the contour of the rear of the vehicle, reducing interference with the surrounding environment during driving.

[0073] When the authorized vehicle is ready to park, the push block at the rear of the vehicle gradually approaches the blocking element on the A-type slider. Since the two have the same magnetic polarity, a repulsive force is generated between them. This repulsive force acts as a non-contact driving force to push the A-type slider to move smoothly along its guide rail.

[0074] When the A-type slider moves to a certain position, it triggers the conduction mechanism of the hydraulic oil circuit. At this time, the oil in the cylinder will be smoothly transported to the hydraulic oil circuit and then enter the hydraulic cylinder through a series of pipes. During this process, the state of the blocking element in the hydraulic cylinder will change, allowing the vehicle to enter the parking area smoothly.

[0075] This built-in magnetic push block can not only reduce the wear and noise caused by physical contact and improve the stability and durability of the system, but also is an electromagnet design that can flexibly control the magnetism of the push block and the repulsive force between it and the blocking element by controlling the power on and off of the electromagnet, thereby achieving more precise and controllable slider movement and hydraulic oil circuit conduction.

[0076] In order to simplify the operation process of triggering the push block to push the blocking element, the length of the base is designed to match the width of the parking area, and the three sliders are placed at the left, middle and right positions of the parking area. In this way, as long as the vehicle can be parked relatively correctly in the designated area, the push block can easily interact with the blocking element on the slider, thereby smoothly realizing the conduction of the hydraulic oil circuit. This design not only reduces the difficulty of operation, but also improves the response speed and reliability of the system.

[0077] In addition, in this application, the base and the cylinder components are designed to be hidden and buried underground, while the intercepting element is exposed on the ground, and a sliding track is set on the ground for the intercepting element. At the same time, the load-bearing plate is long and exposed on the ground. In order to support and stabilize the load-bearing plate, multiple bearing bases are set underground, and these bases are connected to the load-bearing plate through springs. Not only does it improve the overall anti-theft performance and make the equipment safer, but it also takes into account the aesthetics, making the entire parking system neater and more orderly.

[0078] Anything not described in the present invention can be achieved by adopting or drawing on existing technologies.

[0079] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
