[0026] Please see Figure 1-7 A novel in-ground parking lock includes a housing 1 and a door panel 2. The housing 1 has an upward-opening receiving groove 11 in the middle. One end of the door panel 2 is hinged to the side wall of the receiving groove 11. Transmission support assemblies 3 are respectively provided on both sides of the receiving groove 11. (See also...) Figure 6-7 The transmission support assembly 3 includes a guide rail 31, a lead screw 32, a nut sleeve 33, a connecting shaft 34, rollers 35, and a swing arm 36. The guide rail 31 is laid on the bottom wall of the receiving groove 11 and has a sliding groove 311 along its length. The lead screw 32 is rotatably disposed in the sliding groove 311. The nut sleeve 33 is threaded onto the lead screw 32 and moves along the axial direction of the lead screw 32. The connecting shaft 34 passes through both sides of the nut sleeve 33 and the rollers 35 are respectively installed at its protruding ends. One end of the swing arm 36 is hinged to the connecting shaft 34, and the other end is hinged to the bottom wall of the door panel 2.

[0027] This invention features a transmission support assembly 3 within the receiving groove 11 of the housing 1. A rotating lead screw 32 drives a nut sleeve 33, a connecting shaft 34, rollers 35, and a swing arm 36 to move axially along the lead screw 32. This causes the swing arm 36 to swing the door panel 2 around the hinge point on the inner wall of the receiving groove 11, allowing it to open or retract into the groove 11. During this process, the rollers 35 and connecting shaft 34 stably support the nut sleeve 33 as it moves within the slide groove 311. The lead screw 32 resets the nut sleeve, and the nut sleeve 33 provides guidance. This design offers high structural strength, stable movement and support, resistance to damage, high safety, and prevents eccentricity and jamming.

[0028] Please see Figure 6-7 The transmission support assembly 3 includes bearing seats 37 respectively disposed at both ends of the slide groove 311. The two ends of the lead screw 32 are rotatably mounted on the bearing seats 37. A flat key 371 is connected to the bottom wall of the bearing seat 37. A keyway 312 for the flat key 371 to be embedded is formed in the bottom wall of the slide groove 311. In this embodiment, the flat key 371 is welded in the keyway 312. Through the cooperation of the flat key 371 and the keyway 312, the positioning accuracy is higher and the stability is better. Limiting parts 313 extending horizontally towards the center of the slide groove 311 are formed on the top of both sides of the guide rail 31. The limiting parts 313 block the roller 35 above to prevent the roller 35 from jumping upward when rolling, so that the entire transmission support assembly 3 moves more stably.

[0029] The swing arm 36 includes a hinge section 361 and a connecting section 362. There are two hinge sections 361, which are respectively hinged to the door panel 2 and the connecting shaft 34. The two ends of the connecting section 362 are connected to the two hinge sections 361, and the connecting section 362 serves to reinforce the connection strength between the two hinge sections 361. A clearance groove 363 is formed between the two hinge sections 361 to allow the lead screw 32 to pass through, so that the swing arm 36's swing is not interfered with by the rotation of the lead screw 32.

[0030] Please see Figure 3 A drive mechanism 4 is provided within the receiving groove 11. The drive mechanism 4 includes a motor 41, a transmission box 42, and a connecting belt (not shown). The motor 41 is horizontally mounted on the bottom wall of the receiving groove 11. Both ends of the transmission box 42 are connected to two bearing seats 37 respectively. The output shaft of the motor 41 extends into the transmission box 42, and a drive wheel (not shown) is installed at the end of the output shaft. One end of the lead screw 32 passes through one of the bearing seats 37 and extends into the transmission box 42. Please refer to [link / reference]. Figure 6The lead screw 32 extends into the transmission box 42, and a driven wheel 321 is installed at one end. The connecting belt is wound around the driving wheel and the driven wheel 321. In this embodiment, both the driving wheel and the driven wheel 321 are sprockets, and the connecting belt is a chain; or both the driving wheel and the driven wheel 321 are pulleys, and the connecting belt is a conveyor belt. By arranging the connecting belt, the driving wheel, and the driven wheel inside the transmission box 42, it serves to provide waterproofing, fireproofing, and dustproofing, which helps to extend the service life of the drive mechanism 4.

[0031] Please see Figure 4-5 The door panel 2 includes a main body 21 hinged to the side wall of the receiving groove 11 and a cover plate 22 covering the top of the main body 21. The main body 21 has several slots 211 on each of its two side walls. The cover plate 22 has two ends bent downwards to form fastening portions 221 opposite to the side walls of the main body 21. Each fastening portion 221 has several elastic pieces 222 that abut into the corresponding slots 211. Compared to existing screw connections, the direct engagement of the elastic pieces 222 with the slots 211 saves on parts costs and improves the appearance. In this embodiment, several rollers 9 are rotatably mounted on the end of the main body 21 away from its hinge point with the receiving groove 11; the main body 21 is hinged to the side wall of the receiving groove 11 by at least two hinges.

[0032] Please see Figure 3-4 A plurality of pressure plates 5 are provided on the bottom periphery of the door panel 2, and a plurality of support plates 6 adapted to the pressure plates 5 are provided on the bottom periphery of the receiving groove 11. When the door panel 2 is housed in the receiving groove 11, the pressure plates 5 press against the support plates 6. Through the cooperation between the support plates 6 and the pressure plates 5, the door panel 2 can withstand greater pressure and is more stably supported. In this embodiment, a plurality of the pressure plates 5 are provided at the bottom of the panel body 21.

[0033] Please see Figure 1 The box body 1 is provided with a barcode scanning panel 7 on one side of the receiving groove 11. The barcode scanning panel 7 is made of 12mm thick tempered glass, which has a greater load-bearing capacity and is not easy to break. The outer periphery of the box body 1 is connected with a frame 8. The frame 8 is used to fix the box body 1 when it is embedded in the ground, so as to make the installation of the box body 1 more stable.

[0034] The working principle of this novel underground parking lock is as follows: When it is necessary to open the door panel 2 or to retract the door panel 2 into the receiving groove 11, the motor 41 is started. The motor 41 drives the lead screw 32 to rotate through the connecting belt. Under the action of the lead screw 32, the nut copper sleeve 33 moves along the axial direction of the lead screw 32 and drives the roller 35 to roll in the slide groove 311. At the same time, the swing arm 36 swings under the drive of the connecting shaft 34 and drives the door panel 2 to swing around the hinge point with the receiving groove 11 to open or retract to the top of the receiving groove 11, which is convenient and quick.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
