Description

Technical Field

[0001] The invention relates to a three-dimensional parking garage, in particular to a nine-grid intelligent parking garage. Background Art

[0002] With the continuous development of society, more and more cars are entering the market. Whether it is urban buildings, underground parking garages, roadside and residential parking spaces, there is a serious shortage of parking spaces, especially in some large and old residential areas. Due to the lack of parking resources, the roads in residential areas are crowded and overcrowded; parking resources are becoming more and more serious, the parking area is seriously insufficient, illegal parking is often seen, and parking difficulties have become an increasingly prominent contradiction in urban development. How to solve the contradiction between parking supply in cities, communities and residential areas is related to the safety, comfort, ecology and living environment of urban residents and communities. Domestic parking lots are still dominated by flat parking lots, on-road parking lots, off-road parking lots, etc., and the number of three-dimensional parking garages and mechanical parking garages is still very small. In recent years, there have been few new flat parking lots in developed countries. Instead, they have been replaced by fully automated three-dimensional parking garages with modern levels. Replacing flat parking with three-dimensional parking can save limited land resources, improve the efficiency of limited land resources in cities, effectively alleviate traffic congestion and parking difficulties, and replace flat parking with three-dimensional parking. However, although the existing three-dimensional parking garages can save land, due to the rigid structural design and the single reliance on elevators to transport vehicles, the efficiency of entering and exiting the garage has long been unable to meet the requirements of rapid parking of vehicles during peak hours, and cannot meet the requirements of quick parking and quick retrieval. Mechanical parking equipment is divided into nine categories, namely, lifting and lateral movement, vertical circulation, multi-layer circulation, plane movement, aisle stacking, horizontal circulation, vertical lifting, simple lifting, and special car lifts. These types of garages are similar. Among them, the lifting and lateral movement and multi-layer circulation types have given up the consideration of throughput, while the plane movement type tries to achieve the effect of diversion by opening more transmission tracks outside the garage, but it still causes a large number of vehicles to be stranded, and it also consumes too much area in the design of entrances and exits and transportation tracks. Three-dimensional parking garages not only need quantitative development, but also need qualitative improvements in space utilization, safety and convenience, and ecological environmental protection. Summary of the invention

[0003] The purpose of the present invention is to break through the "pseudo-stereoscopic" spatial layout of most stereoscopic parking garages, and to provide a stereoscopic parking garage with better space utilization and higher scheduling efficiency by designing the spatial structure and scheduling method, so as to achieve the experience requirements of quick parking and quick retrieval.

[0004] Basic plan 1:

[0005] The nine-grid intelligent parking garage includes a garage body with a concrete structure and an intelligent consignment system for consigning vehicles. The garage body includes a number of parking units, and the parking unit consists of 8 parking spaces located on the same plane and a vehicle transportation area located in the middle of the parking spaces; the 8 parking spaces and the vehicle transportation area of ​​the parking unit are distributed in a nine-grid pattern, and the parking units are stacked up and down to form a vertical parking group, and the vehicle transportation areas of the parking units in the vertical parking group form an elevator shaft, and the elevator shaft is provided with an elevator lifting platform that can move up and down; the intelligent consignment system can carry vehicles and drive the vehicles to move horizontally and longitudinally, and a temporary parking area is provided under the garage body, and the length direction of the temporary parking area is parallel to the length direction of the parking unit, and the width direction of the temporary parking area is parallel to the width direction of the parking unit.

[0006] The beneficial effects of this solution are:

[0007] The parking area is divided into nine-square grids, so that the space of the parking unit can be fully utilized; the middle position of the nine-square grid is used for dispatching vehicles, and an elevator lifting platform is set in the middle vehicle transportation area, and the elevator lifting platform only moves up and down to dispatch vehicles; thus, the vehicle transportation area is set to the same rectangle as the vehicle, and the elevator lifting platform does not rotate, so that the space of the parking unit can be made more compact and occupy less area.

[0008] By dispatching vehicles horizontally and vertically through the intelligent consignment system, the vehicles to be stored can be sent to the parking spaces at the four corners of the vehicle transport area to make full use of the parking space. In addition, the parking and retrieval methods of the basic plan 2 and the priority of the parking spaces can be divided to improve the efficiency of parking and retrieval.

[0009] Preferred Solution 1: As a further optimization of Basic Solution 1, a plurality of vertical parking groups are provided in the garage body to fully utilize the space of the garage body.

[0010] Preferred Option 2: As a further optimization of Preferred Option 1, the intelligent shipping system includes a pallet and an intelligent trailer that can move laterally and longitudinally; a storage space is provided under the pallet for the intelligent trailer to pass through laterally and longitudinally, and a hydraulic jack is provided on the top of the intelligent trailer.

[0011] In the preferred solution two, a pallet is used to carry the vehicle. The pallet has a larger load-bearing capacity and higher strength, and therefore better reliability. However, the pallet must be kept under the vehicle, so each parking space needs to be equipped with a pallet, which makes the investment cost of the pallet higher.

[0012] Preferred solution three: As a further optimization of preferred solution two, the intelligent consignment system includes at least 4 intelligent carts, which can move laterally and vertically. The 4 intelligent carts are connected by signals to form a consignment group. The intelligent carts in the same consignment group move synchronously. The intelligent cart is provided with a "∪"-shaped slot, which can be embedded in the tire of the vehicle and lift the tire upward.

[0013] In the preferred solution three, smart carts are used to transport vehicles. Four smart carts form a group and hold the four wheels of the vehicle respectively, making it more flexible and maneuverable to move the vehicle using smart carts. When the vehicle is parked in a parking space, the smart cart does not need to remain under the vehicle, but can return to the temporary parking area to transport the next vehicle. Therefore, the investment in smart carts can be reduced, reducing investment costs.

[0014] Preferred Option 4: As a further optimization of Preferred Option 3, the elevator shaft extends downward to the bottom floor of the garage body. When the elevator lifting platform is at the bottom floor, the elevator lifting platform is level with the ground; thereby facilitating the intelligent consignment system to move the vehicle onto the elevator lifting platform.

[0015] Preferred Option 5: As a further optimization of Preferred Option 4, the temporary parking area is provided with distance sensors distributed in a rectangular array, the rectangular sensors are electrically connected to the wheelbase information module, and the wheelbase information module is connected to the smart car signal; by measuring the distance between the vehicle's tires and the ground through the distance sensors, the vehicle's wheelbase and wheelbase can be accurately determined.

[0016] Basic solution 2:

[0017] The method for parking and retrieving a car in a nine-grid intelligent parking garage is characterized by comprising a parking step and a retrieving step;

[0018] After the vehicle to be stored is parked in the temporary parking area, the parking steps are performed. The parking steps include:

[0019] (1) The vehicle is lifted by the intelligent consignment system and moved to the elevator lifting platform through the intelligent consignment system;

[0020] (2) The elevator lift platform lifts the vehicle to the nearest and highest priority parking unit;

[0021] (3) The intelligent consignment system moves the vehicle to the nearest parking space with the highest priority;

[0022] Perform the vehicle pickup steps before the pickup time specified by the pickup personnel. The vehicle pickup steps include:

[0023] (1) The elevator platform is lowered to the parking unit where the vehicle to be picked up is located;

[0024] (2) The intelligent consignment system lifts the vehicle and moves it to the elevator platform;

[0025] (3) The elevator lift platform lowers the vehicle to the bottom floor of the garage, and the intelligent consignment system moves the vehicle to the temporary parking area.

[0026] Preferred Solution 6: As a further optimization of Basic Solution 2, the parking space priority within the same parking unit is set according to the following conditions:

[0027] The first priority parking spaces are the six spaces located on both sides of the vehicle delivery area;

[0028] The second priority parking spaces are the two spaces located between the first priority spaces;

[0029] The parking unit priority is set according to the following conditions:

[0030] All or part of the first priority parking spaces in the first priority parking units are vacant, and all the second priority parking spaces are vacant;

[0031] The first priority parking spaces in the second priority parking units are fully occupied and all the second priority parking spaces are vacant;

[0032] The parking spaces of the first priority level in the parking unit of the third priority level are fully occupied, and the parking spaces of the second priority level are partially vacant. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is further described in detail through specific implementation methods:

[0041] The figure marks in the drawings of the specification include: a pallet 10, an intelligent trailer 20, a mobile body 21, a hydraulic push rod 22, a driving wheel 23, a main shaft 24, an air cavity 25, a piston 26, a centrifugal block 27, an air intake check valve 28, an intelligent car 30, a transverse moving wheel 31, a longitudinal moving wheel 32, a transverse driving motor 33, a clamping pallet 34, and a third hydraulic push rod 35.

[0042] Embodiment 1:

[0043] The nine-square grid intelligent parking garage of embodiment 1 includes a garage body of concrete structure and an intelligent consignment system for consigning vehicles. The garage body is a concrete frame structure, and there is no partition wall inside the garage body, and the garage body may not have an outer wall. The garage body includes a plurality of parking units arranged on each floor of the garage body; and the length direction of each parking unit is arranged longitudinally, and the width direction of the parking unit is arranged transversely. The parking units are evenly divided into a nine-square grid shape, and the center of the parking unit is the vehicle transport area, and the periphery to which the vehicles are transported is surrounded by 8 parking spaces. The parking units are extended in the vertical direction on each floor of the garage body to form a vertical parking group, and the vehicle transport area of ​​the parking units in the same vertical parking group is connected from top to bottom to form an elevator shaft. The vertical parking group extends to the surroundings and covers the garage body, thereby making full use of the space of the garage body.

[0044] The elevator shaft extends downward to the bottom floor of the garage body. An elevator lifting platform is installed inside the elevator shaft. When the elevator lifting platform descends to the lowest position, the elevator lifting platform is level with the ground. The structure of the elevator lifting platform is similar to the elevator in the existing building structure, but there are no partitions around it, so as to facilitate the movement of vehicles to the parking space.

[0045] The intelligent shipping system in this embodiment includes a pallet 10 and an intelligent trailer 20. Support columns are fixed to the four corners of the bottom of the pallet, so that a storage space is formed under the pallet 10, and the intelligent trailer 20 can freely enter the storage space from the four sides under the pallet 10, that is, the intelligent trailer 20 can freely pass under the pallet 10 in the horizontal and vertical directions.

[0046] The smart trailer 20 includes a mobile body 21 and four hydraulic push rods 22. The hydraulic push rods 22 are installed at the four corners of the mobile body 21. When the smart trailer 20 moves to the accommodation space below the pallet 10, the hydraulic push rods 22 lift the pallet 10 so that the pallet 10 can leave the ground. Therefore, the movement of the smart trailer 20 will drive the pallet 10 and the vehicle on the pallet 10 to move, thereby achieving the purpose of moving the vehicle. When the vehicle moves to the designated parking space, the hydraulic push rods 22 on the top of the smart trailer 20 are retracted, and the pallet 10 can be placed in the designated parking space; during the parking process, the pallet 10 always remains under the vehicle.

[0047] Four universal wheels are provided at the four corners of the bottom of the mobile body 21, and a driving mechanism is provided below the mobile body 21. The driving mechanism includes a bracket and a driving motor; the bracket is rotatably connected to the mobile body, and the driving motor is fixed on the bracket. The driving motor adopts a dual-axis servo motor, and driving wheels 23 are fixed at both ends of the output shaft of the dual-axis servo motor. In addition, a lifting device is provided on the bracket, and the lifting and lowering of the driving wheel can be realized by the lifting device. The lifting mechanism can adopt a cylinder or a hydraulic cylinder. The driving wheel moves up to leave the ground; the driving wheel descends and the driving wheel contacts the ground. At this time, the universal wheel and the driving wheel 23 will contact the ground at the same time to support the smart trailer. The driving motor drives the driving wheel 23 to rotate, and the smart trailer 20 can be driven to move.

[0048] A stepper motor is installed on the mobile body 21 to drive the bracket to rotate relative to the mobile body 21, so that the direction of movement of the smart trailer 20 can be changed. Specifically, if the axial direction of the driving wheel 23 is in the horizontal direction, the driving wheel 23 can be directly moved down to drive the smart trailer 20 to move in the longitudinal direction; when it is necessary to switch to horizontal movement, the driving wheel 23 is moved up, and then the bracket is rotated 90° relative to the mobile body 21 by the stepper motor, and then the driving wheel 23 is moved down, so that the smart trailer 20 can be driven to move in the horizontal direction.

[0049] A temporary parking area is provided under the main body of the garage. The temporary parking area is provided with several temporary parking spaces. The length direction of the temporary parking spaces is arranged longitudinally, and the width direction of the temporary parking spaces is arranged transversely; thus, it is convenient for vehicles to enter the elevator lifting platform directly by moving horizontally and longitudinally.

[0050] The steps of storing and retrieving a car using the smart parking system of the embodiment are as follows:

[0051] After the vehicle to be stored is parked on the pallet of the intelligent consignment system in the temporary parking area, the parking steps are performed:

[0052] (1) Move the vehicle to the elevator platform by moving the vehicle longitudinally and transversely;

[0053] (2) The elevator lift platform lifts the vehicle to the nearest and highest priority parking unit;

[0054] (3) The intelligent consignment system moves the vehicle to the nearest parking space with the highest priority;

[0055] Perform the vehicle pickup steps before the pickup time specified by the pickup personnel. The vehicle pickup steps include:

[0056] (1) The elevator platform is lowered to the parking unit where the vehicle to be picked up is located;

[0057] (2) The intelligent consignment system lifts the vehicle and moves it to the elevator platform;

[0058] (3) The elevator lift platform lowers the vehicle to the bottom floor of the garage, and the intelligent consignment system moves the vehicle to the temporary parking area.

[0059] The parking space priorities within a parking unit are set according to the following conditions:

[0060] The first priority parking spaces are the six parking spaces located on both sides of the vehicle delivery area, such as Figure 1 As shown, parking spaces 1#, 2#, 3#, 4#, 5#, and 6# are the first priority parking spaces;

[0061] The second priority parking spaces are the two parking spaces located between the first priority parking spaces, such as Figure 1 As shown, parking spaces 7# and 8# are the second priority parking spaces;

[0062] Parking unit priorities are set according to the following conditions:

[0063] All or part of the first priority parking spaces in the first priority parking units are vacant, and all the second priority parking spaces are vacant;

[0064] The first priority parking spaces in the second priority parking units are fully occupied and all the second priority parking spaces are vacant;

[0065] The parking spaces of the first priority level in the parking unit of the third priority level are fully occupied, and the parking spaces of the second priority level are partially vacant.

[0066] like Figure 2 As shown, in the vehicle picking step, when the parking unit is in the first priority and second priority states, the vehicles in the 1#, 3#, 4#, and 6# parking spaces are moved to the elevator lifting platform according to the following steps (taking the vehicle in the 1# parking space as an example):

[0067] (1) Move the vehicle in parking space #1 longitudinally to parking space #7;

[0068] (2) Then move the vehicle horizontally onto the elevator lifting platform.

[0069] like Figure 3As shown, in the vehicle picking step, when the parking unit is in the third priority state, if there is a vehicle parked in the 8# parking space, the vehicles in the 3# and 6# parking spaces are moved to the elevator lifting platform according to the following steps (taking the vehicle in the 3# parking space as an example):

[0070] (1) Move the vehicle in parking space #8 horizontally to parking space #7;

[0071] (2) Move the vehicle in parking space #3 longitudinally to parking space #8;

[0072] (3) Then move the vehicle horizontally onto the elevator lifting platform.

[0073] like Figure 4 As shown, in the vehicle picking step, when the 8 parking spaces on the parking unit are fully loaded, the vehicles on the 1#, 3#, 4#, and 6# parking spaces are moved to the elevator platform according to the following steps (taking the vehicle on the 1# parking space as an example):

[0074] (1) Move the vehicle in parking space 7# to the elevator platform;

[0075] (2) Move the vehicle from parking space 1# to parking space 7#.

[0076] (3) The vehicle in parking space 2# moves to parking space 1#.

[0077] (4) The vehicle on the elevator platform moves to parking space No. 2;

[0078] (5) Move the vehicle in parking space No. 7 to the elevator platform.

[0079] The vehicle originally in parking space No. 1 is moved to the elevator lifting platform.

[0080] In addition, when the 8 parking spaces on the parking unit are full, you can also follow the steps below to pick up the car:

[0081] (1) Move the vehicle in parking space 7# to the elevator platform;

[0082] (2) The elevator platform is lowered to the floor of another parking unit with vacant spaces, the vehicle is moved to the parking unit with vacant spaces, and then the elevator platform is returned;

[0083] (3) Move the vehicle from parking space #1 to parking space #7, and then move it onto the elevator platform.

[0084] The vehicle originally in parking space No. 1 is moved to the elevator lifting platform.

[0085] Embodiment 2:

[0086] The difference between the first embodiment and the second embodiment is that the intelligent consignment system in the second embodiment adopts a consignment marshaling mobile vehicle composed of intelligent trolleys. As shown in the figure, the intelligent trolley includes a wheel support plate, a lateral motion part and a longitudinal motion part. The lateral motion part includes two groups of lateral moving wheels and a lateral drive motor. The lateral drive motor adopts a dual-axis stepper motor. The lateral drive motor is fixed on the left side of the wheel support plate, one group of lateral moving wheels is respectively fixed on the two output shaft ends of the lateral drive motor, and the other group of lateral moving wheels is connected through a rotating shaft, and the rotating shaft is set on the right side of the wheel clamping support plate, and the rotating shaft is rotatably connected with the wheel clamping support plate.

[0087] The bottom of the wheel support is also equipped with a battery, a controller and a suspension, and the suspension is connected to the bottom of the wheel support through the first hydraulic push rod. The longitudinal motion part includes two groups of longitudinal drive wheels and a longitudinal drive motor. The longitudinal drive motor adopts a double-axis stepper motor. The longitudinal drive motor is fixed on the suspension and located at the rear of the wheel holding support. One group of longitudinal drive wheels is respectively fixed on the two output shaft ends of the longitudinal drive motor, and the other group of longitudinal moving wheels is set at the front end of the wheel support and is connected to the suspension rotation.

[0088] When the smart car needs to move in the lateral direction, the controller controls the first hydraulic push rod to contract, so that the suspension moves upward, and the longitudinal moving wheel will leave the ground. The controller controls the lateral drive motor to run, and the smart car can be driven to move in the lateral direction. When the smart car needs to move in the longitudinal direction, the controller controls the first hydraulic push rod to push the suspension downward, and the longitudinal moving wheel will contact the ground, while the lateral moving wheel will leave the ground. At this time, the controller controls the longitudinal drive motor to run, and the smart car can be driven to move in the longitudinal direction. The driving structure and driving method of the smart trailer in Example 1 can also adopt the structure of the smart car in Example 2.

[0089] The front end of the wheel support plate is provided with a "∪"-shaped slot, and the upper part of the wheel support plate is connected to the clamping support plate through the second hydraulic push rod, and the clamping support plate is also provided with a slot, and the slots on the wheel support plate and the clamping support plate overlap. A third hydraulic push rod is provided on the opposite side of the clamping slot of the clamping support plate; by controlling the movement of the smart car, the wheel is embedded in the slot, and then the first hydraulic rod is extended through the controller, so that the clamping support plate clamps the wheel; then the controller controls the second hydraulic push rod to lift the clamping support plate, so that the vehicle can be lifted off the ground, so that the smart car can move the vehicle conveniently.

[0090] When moving the vehicle, the four smart cars are connected through signals to form a consignment group, and the smart cars in the same consignment group move synchronously to move the vehicle.

[0091] Distance sensors distributed in a rectangular array are arranged on the ground of the temporary parking spaces in the temporary parking area. The rectangular sensors are electrically connected to the wheelbase information module, and the wheelbase information module is connected to the smart car signal. When the vehicle is parked in the temporary parking space, the wheels are in contact with the ground, and the distance between the distance sensor under the wheel and the wheel is zero, so that the position of the tire of the vehicle can be located, and the wheelbase and wheelbase information of the vehicle can be determined. The smart car can locate the wheel position of the vehicle through the information fed back by the wheelbase information module and lift the vehicle.

[0092] Embodiment three:

[0093] The difference between the third embodiment and the second embodiment is that in the fourth embodiment, the temporary parking area includes a temporary parking space for waiting to park and a temporary parking space for waiting to be picked up; when a vehicle needs to be stored, the vehicle to be stored is parked in the temporary parking space for waiting to park. When a vehicle needs to be picked up, a pick-up time is agreed before picking up the vehicle, and the vehicle to be picked up is moved to the temporary parking space for waiting to be picked up before the pick-up time, and then the pick-up personnel drive away the vehicle to be picked up at the pick-up time. In addition, a timing device is provided on the temporary parking space for waiting to be picked up. If the pick-up personnel do not drive away the vehicle at the pick-up time, an additional fee will be charged according to the charging standard of the temporary parking space for waiting to be picked up.

[0094] Embodiment 4:

[0095] The difference between the fourth embodiment and the first embodiment is that in the third embodiment, the elevator shaft is provided with a first elevator lifting platform and a second elevator lifting platform that can operate independently, and the elevator shaft extends downward to below the bottom floor of the garage body to form a sinking area, and the sinking area can accommodate the first elevator lifting platform and the second elevator lifting platform at the same time. When requesting to take out vehicles from different floors at the same time in the same vertical parking formation, the first elevator lifting platform can be moved to a high floor, and the second elevator lifting platform can be moved to a low floor, and the vehicles to be taken can be moved to the first elevator lifting platform and the second elevator lifting platform respectively for standby, and then the second elevator lifting platform can be moved to the bottom floor, and after the vehicles on the second elevator lifting platform are moved out; the second lifting platform is moved to the sinking area, and then the first elevator lifting platform is moved to the bottom floor to move the vehicles on the first elevator lifting platform out. In addition, distance sensors are provided on the upper surface of the second lifting platform and the lower surface of the first lifting platform. The distance sensors are connected to the controller, and the distance sensors are arranged on the ground that will not be blocked by the measurement. When the distance between the first lifting platform and the second lifting platform is less than the height of one floor, the first lifting platform and the second lifting platform will be braked to avoid collision between the first lifting platform and the second lifting platform, thereby improving safety.

[0096] Embodiment five:

[0097] The difference between the fifth embodiment and the first embodiment is that in the fifth embodiment, Figure 7As shown, an air cavity 25 is provided in the movable body, and the bracket rotates with the movable body through the main shaft 24. The main shaft 24 is driven by a stepping motor, and the main shaft 24 closes the air cavity, so that the air cavity forms an annular sealed cavity. A piston 26 that can slide in the radial direction of the main shaft 24 is provided on the outer wall of the annular sealed cavity, and a compression spring is provided at the end of the piston 26 facing outward to abut against the piston 26. When the pressure in the air cavity 25 increases, the pressure in the air cavity 25 will squeeze the piston 26 outward, and when the pressure in the air cavity decreases, the piston 26 moves toward the main shaft 24 under the action of the compression spring to achieve reset.

[0098] A brake device controlled by a flexible shaft is provided on the universal wheel, and one end of the flexible shaft is connected to the piston; that is, when the pressure in the air cavity 25 increases, the piston 26 will control the brake device through the flexible shaft to put the universal wheel in a braking state; after the pressure in the air cavity 25 decreases, the brake device releases the universal wheel again.

[0099] The main shaft 24 is provided with a mounting hole arranged along the radial direction of the main shaft 24, and a centrifugal block 27 is slidably connected in the mounting hole; the centrifugal block 27 is connected to the bottom of the mounting hole through a tension spring. When the main shaft 24 rotates, the centrifugal block 27 will be subjected to the centrifugal force, so that the centrifugal block 27 overcomes the tension of the tension spring and slides outward, that is, the centrifugal block 27 will slide out of the mounting hole to squeeze the air inside the air cavity, thereby increasing the pressure inside the air cavity. Therefore, during the rotation of the main shaft 24, the air cavity is in a state of high pressure, and the universal wheel is in a braking state at this time. Thereby, when the driving wheel 23 is not in contact with the ground, the universal wheel 23 can be prevented from slightly moving, causing the vehicle to deviate from the horizontal or longitudinal direction; and when the driving wheel 23 is in contact with the ground, the intelligent trailer 20 can be braked by braking the main shaft of the dual-axis servo motor.

[0100] An air intake check valve 28 is provided on the side wall of the air cavity 25, the air intake end of the air intake check valve 28 is connected to the outside, and the air outlet end of the air intake check valve 28 is connected to the air cavity. When the rotating shaft 24 stops rotating, the centrifugal block 27 returns to the mounting hole under the action of the tension spring, but since the centrifugal block and the tension spring constitute a spring oscillator structure, the centrifugal block 27 will be in a state of repeated vibration during the return process of the centrifugal block 27; since the air cavity 25 cannot ensure complete air tightness during the high pressure process, it will cause air loss in the air cavity, and by providing the air intake check valve 28 and coordinating the repeated vibration of the centrifugal block 27, air can be replenished into the air cavity.

[0101] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
