Description

Technical Field

[0001] This invention relates to a multi-level parking system, and more particularly to a multi-level parking system suitable for parking electric vehicles. Background Technology

[0002] Electric vehicle user manuals state that the best way to extinguish a battery fire is by immersion. Current multi-level parking systems have densely packed parking spaces, so a fire in a parked electric vehicle could have serious consequences. Therefore, to meet fire safety requirements, many multi-level parking systems are equipped with fire extinguisher boxes. However, these boxes come in various types, some fixed to the garage foundation. Their drawback is the limited number of boxes; if multiple electric vehicles catch fire, it's impossible to immerse them all in the fire extinguisher box.

[0003] Taking a lifting and traversing parking system as an example, it includes a three-dimensional shelf, a traversing frame, a platform, and a fire sprinkler system. The three-dimensional shelf has multiple vertically distributed parking spaces and at least one vertical passage. A crossbeam rail connects the vertical passage to each parking space. The traversing frame is movably mounted on the crossbeam rail and also has a cable-stayed device and a rectangular box frame. The cable-stayed device connects to the platform and controls the platform's lifting and lowering movement below the rectangular box frame. A charging gun is installed on the platform. An open rectangular box frame is located within each parking space, with one side of the open rectangular box frame open near the vertical passage. The platform has a vertical panel on the corresponding open side of the rectangular box frame. Therefore, after the platform enters the parking space, it connects with the open rectangular box frame to form a fire sprinkler box. However, the platform and the open rectangular box frame in this structure cannot form a fire sprinkler box within the vertical passage. If a vehicle catches fire, the fire sprinkler box cannot be moved out to the passage along with the fire sprinkler, affecting vehicles parked above. Furthermore, because at least one side of the platform has a vertical panel, it hinders the entry and exit of vehicles and personnel. Summary of the Invention

[0004] The purpose of this invention is to provide a three-dimensional parking system suitable for electric vehicles, which has a simple and reasonable structure, charging and fire-fighting functions, and a fire box that can be moved out of the passage.

After the fire box is formed, water can be injected into the fire box through spraying, water injection equipment, etc., to cool down or extinguish the fire of electric vehicles in the fire box that are in high temperature or on fire. In addition, the rectangular box frame can be moved laterally into the vertical channel, so that the fire box can be formed in the vertical channel and the fire vehicle can be moved into the vertical channel to reduce the impact on the vehicles in the parking space above.

[0019] (2) This type of three-dimensional parking equipment suitable for electric vehicles is equipped with an elastic enclosure and sealing strip between the rectangular box frame and the platform, so that the parking base and the enclosure can continue to move closer together after they are close to each other, making the sealing strip more tightly pressed, thus forming a water storage fire box with better sealing effect; and the elastic enclosure is lightweight, easy to install, has a small spring load capacity, and a long service life.

The movable connector assembly 40 includes a movable connector 7, and the movable connector 7 is provided with an output electrode 74 corresponding to the movable electrode 610.

[0050] The movable electrode 610 of the fixed connector 6 is electrically connected to the output line 101 of the charging pile 10, and the output electrode 74 of the movable connector 7 is electrically connected to the input line 301 of the charging gun 30.

[0051] An external spring 63 is provided between the fixed base 61 and the fixed joint 6. The external spring 63 and the internal spring 68 have the same axial direction. The elastic force of the external spring 63 is greater than that of the internal spring 68.

[0052] The surface of the fixed joint 6 is provided with a hanging plate, the fixed seat 61 is provided with a bolt 62, the external spring 63 is sleeved on the bolt 62 and pressed between the fixed seat 61 and the hanging plate, and the bolt 62 passes through the hanging plate and is connected to the limit nut 64.

[0053] The fixed connector 6 has a cavity 66 corresponding to the outer end of the movable electrode 610, and the movable connector 7 has a boss 71 corresponding to the cavity 66. The outer end of the output electrode 74 is located on the top surface of the boss 71, and the cavity 66 and the conical surface of the boss 71 are engaged.

[0054] The fixed connector 6 has a sliding cavity corresponding to the inner end of the movable electrode 610, and the sliding cavity leads to the surface of the fixed connector 6. The surface of the fixed connector 6 is also provided with a cover plate to cover the sliding cavity. The inner end of the movable electrode 610 has a movable connector, which is slidably disposed in the sliding cavity. The insulating pad 67 and the built-in spring 68 are disposed in the sliding cavity and pressed between the movable connector and the cover plate. The surface of the movable connector has a radially arranged wiring hole, and the end of the movable connector facing the insulating pad 67 has an axially arranged screw hole, which communicates with the wiring hole. A locking screw 72 is disposed in the screw hole, and the insulating pad 67 and the cover plate have clearance holes corresponding to the locking screw 72. The surface of the fixed connector 6 has an elongated insertion hole 65, which communicates with the sliding cavity.

[0055] The active electrode 610 includes a power supply electrode and a signal electrode; the fixed connector 6 is also equipped with a temperature sensor, which is located next to the power supply electrode.

[0056] The movable connector 7 is fixedly connected to the output electrode 74. One end of the output electrode 74 protrudes from the surface of the movable connector 7, and the other end of the output electrode 74 passes through to the other side of the movable connector 7 and cooperates with the snap ring. A wiring hole is provided radially on the outer periphery of the output electrode 74, and a screw hole communicating with the wiring hole is provided at the other end of the output electrode 74. A locking screw 72 is provided in the screw hole. The surface of the movable connector 7 is also provided with a circular insertion hole corresponding to the wiring hole.

[0057] The movable joint assembly 40 also includes a connecting seat 73, which is connected to the movable joint 7. Both the connecting seat 73 and the fixed seat 61 are L-shaped.

[0058] The top of the three-dimensional shelf 1 is equipped with a lightning rod 17. The three-dimensional shelf 1 is set on the foundation 200, and the foundation 200 is provided with an entrance 2001 at the lower end of the vertical passage 16, and a ground parking space is provided below the parking space 15.

[0059] Its working principle is as follows: The transverse frame 2 carries the rectangular box frame 4 and the platform 3 laterally on the crossbeam track 12, thereby entering the parking space 15 or the vertical channel 16. When the transverse frame 2 is fully inside the vertical channel 16, the platform 3 can be raised and lowered by the cable device 20 to stop and retrieve the vehicle. During the rise of the platform 3, the positioning socket 33 is guided directly or through the guide cone surface and then engages with the guide positioning pin 21 to align the platform 3 with the rectangular box frame 4. As it continues to rise, the boss 71 of the movable joint 7 enters the cavity 66 of the fixed joint 6, and the boss 71 engages with the cone surface of the cavity 66 to further align and finally engage the movable electrode 610 and the output electrode 74. If the platform 3 continues to rise slightly due to cable engagement issues after the movable joint 7 engages with the fixed joint 6, it is buffered by the external spring 63. When the temperature sensor detects that the temperature rise of the parking space is too high, the spray water supply will be activated to cool the vehicle.

[0060] Example 2 differs from Example 1 in that: See [link to example 1] Figures 11 to 17 As shown, an elastic enclosure device 9 and a sealing strip 46 are provided between the rectangular box frame 4 and the platform 3. By controlling the platform 3 and the rectangular box frame 4 to move closer to each other, the platform 3, the elastic enclosure device 9 and the sealing strip 46, and the rectangular box frame 4 together form a fire box that can store water.

[0061] The sealing strip 46 is connected to one end of the elastic enclosure device 9, and the other end of the elastic enclosure device 9 is connected to the lower end of the rectangular box frame 4.

[0062] The elastic enclosure device 9 includes an annular soft waterproof and fireproof material 91 and an elastic support for supporting the soft waterproof and fireproof material. The elastic support is connected between the upper and lower ends of the annular soft waterproof and fireproof material 91. The sealing strip 46 is directly or through the frame 461 connected to the lower or upper end of the annular soft waterproof and fireproof material 91.

[0063] The annular soft waterproof and fireproof material 91 is a combination of waterproof cloth 912 and fireproof cloth 911, with the fireproof cloth 911 located inside the waterproof cloth 912.

[0064] A guide is also provided between the elastic enclosure device 9 and the rectangular box frame 4 or the platform 3, and the guide slides vertically with the rectangular box frame 4.

[0065] The lower end of the rectangular box frame 4 is provided with a flange 47. The upper end of the annular flexible waterproof and fireproof material 91 is clamped on the flange 47 by an upper pressure plate 95, and the lower end of the annular flexible waterproof and fireproof material 91 is clamped on the frame 461 by a lower pressure plate 94. The guide is a guide rod 93. The lower end of the guide rod 93 is fixedly engaged with the frame 461, and the upper end of the guide rod 93 passes through the upper pressure plate 95 and the flange 47 and slides with them. The elastic support is a spring 92. The spring 92 is sleeved on the guide rod 93 and pressed between the upper pressure plate 95 and the lower pressure plate 94.

[0066] The guide rod 93 has several rods, which are distributed in a ring around the outer periphery of the annular soft waterproof and fireproof material 91.

[0067] The frame 461 is provided with a water inlet connector 43 and a water outlet connector 44, which are respectively connected to the inner side of the frame 461.

[0068] The elastic enclosure device 9 is provided with a fixed connector 6 that is electrically connected to the charging pile 10.

[0069] Its working principle is as follows: The rectangular box frame 4 is suspended on the shelf of the three-dimensional parking equipment by the transverse frame 2. The transverse frame and the shelf are in a fixed or transverse cooperation relationship. When the platform 3 is lowered to the ground, it is convenient for vehicles to be parked and retrieved. When the parked vehicle is an electric vehicle, the charging gun can also be inserted into the charging port of the electric vehicle. The platform 3 rises towards the rectangular box frame 4. When it rises to a certain height, the platform 3 contacts the sealing strip 46. After the platform 3 contacts the sealing strip 46, the platform 3 can continue to rise to a certain height, so that the spring 92 of the elastic enclosure device 9 is compressed to a certain extent, so that the sealing strip 46 and the top surface of the platform 3 are in closer contact, and the sealing effect is better.

[0070] Example 3 differs from Example 1 or 2 in that the platform has three relative stopping heights: the stopping height at the bottom of the vertical channel, the parking height when the electrical connector is connected and the platform is separated from the rectangular box frame, and the fire-fighting height when the platform and the rectangular box frame are close together to form a fire box.

[0071] Its working principle is as follows: When the platform rises to a certain height (parking height position), the movable joint and the fixed joint first achieve conductive connection, but at this time the platform and the sealing strip are separated. When it is necessary to close the platform and the sealing strip (such as when the parked electric vehicle is too hot or on fire and needs to be cooled and soaked for fire extinguishing), the platform is further controlled to rise to the fire-fighting height position. This principle avoids long-term collision contact between the sealing strip and the platform, thereby improving the service life of the sealing strip.
