It can not only prevent others from illegally occupying private parking spaces and protect the legitimate rights and interests of vehicle owners, but also alleviate the parking difficulty problem to a certain extent, and improve the turnover rate and utilization efficiency of parking spaces.

[0004] In traditional parking locks, the swing arm of the parking lock is usually only supported by the output shaft, and the driven shaft is simply fixed, resulting in friction between the driven shaft of the swing arm and the mating part, generating abnormal noises, which affect the product quality and the sense of experience.

[0039] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0040] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.

[0041] This embodiment relates to a rotary connection component, such as Figures 1 - 7As shown, it includes a first mounting seat 100 and a rotating connection device 200 arranged on the first mounting seat 100; wherein the rotating connection device 200 includes a first rotating connection member 210, and the first rotating connection member 210 is provided with a first rotating assembly hole 211 running through its opposite ends. The swing arm driven shaft 700 is arranged in the first rotating assembly hole 211 and can rotate relative to the hole wall of the first rotating assembly hole 211. An oil storage tank 212 is provided on the hole wall of the first rotating assembly hole 211. The oil storage tank 212 is provided with a lubricant for reducing the friction coefficient between the swing arm driven shaft 700 and the first rotating assembly hole 211. Optionally, the oil storage tank 212 is threaded or annular, and the first rotating connection member 210 is a bearing The first mounting seat 100 is in the shape of a block or a vertical plate. Furthermore, when the driving device drives the swing arm active shaft to drive the swing arm body to move so as to achieve the purpose of locking or unlocking the parking space, the swing arm driven shaft 700 rotates relative to the hole wall of the first rotating assembly hole 211. Since an oil storage tank 212 is provided on the hole wall of the first rotating assembly hole 211, a storage space for lubricating oil can be formed on the hole wall of the first rotating assembly hole 211, thereby increasing the storage capacity of lubricating oil and ensuring that the lubricating oil of the first rotating connector 210 can fully lubricate the bearing surface for a long time during operation, thereby reducing the friction coefficient, reducing energy loss, and improving mechanical efficiency, thereby ensuring that the swing arm runs smoothly without abnormal noise. It can be understood that the driving device is a motor.

[0042] See Figures 2 - 3 、 Figure 5 In this embodiment, the rotating connection device 200 also includes a stable assembly seat 220, and a second rotating assembly hole 221 is provided on the stable assembly seat 220. The first rotating connection member 210 is arranged in the second rotating assembly hole 221, and the outer side wall of the first rotating connection member 210 and the second rotating assembly hole 221 can rotate relative to each other. Optionally, the stable assembly seat 220 is a bearing seat. It can be understood that the second rotating assembly hole 221 is a through hole passing through the opposite ends of the stable assembly seat 220. Since the outer side wall of the first rotating connection member 210 and the second rotating assembly hole 221 can rotate relative to each other, the rotation requirements of the first rotating connection member 210 in different directions and angles can be met.

[0043] In this embodiment, an annular stopper 222 is provided at one end of the second rotational assembly hole 221 away from the first mounting seat 100. The annular stopper 222 is used to prevent the first rotational connector 210 from falling out of the second rotational assembly hole 221. It is understandable that the inner diameter of the annular stopper 222 is smaller than the aperture of the second rotational assembly hole 221 and the outer diameter of the first rotational connector 210. The stopper 222 is provided with a fourth rotational assembly hole 223 that is clearance-matched with the swing arm driven shaft 700. The provision of the annular stopper 222 not only prevents the first rotational connector 210 from falling out of the second rotational assembly hole 221, but also allows the fourth rotational assembly hole 223 on the stopper 222 to clearance-match with the swing arm driven shaft 700. Rationally controlling the diameter difference between the fourth rotational assembly hole 223 and the swing arm driven shaft 700 can reduce lubricant leakage and extend the effective lubrication time.

[0044] See Figures 2 - 3 、 Figures 6 - 7 In this embodiment, it also includes a second mounting seat 300 and a second rotating connector 310 provided on the second mounting seat 300. The second rotating connector 310 is provided with a third rotating assembly hole 311. The second rotating connector 310 is arranged in parallel with the first rotating connector 210.

Optionally, the second mounting seat 300 is in a block shape or a vertical plate shape, and the second rotating connector 310 is a bearing, which can be specifically Ball bearing, the third rotating assembly hole 311 passes through the opposite ends of the second rotating connector 310, the midpoint of the first rotating assembly hole 211 and the midpoint of the third rotating assembly hole 311 are on a straight line. During assembly, the end of the swing arm driven shaft 700 is passed through the first rotating assembly hole 211 and the third rotating assembly hole 311 in turn. It can be understood that the first rotating connector 210 and the second rotating connector 310 are arranged in parallel to jointly support the swing arm driven shaft 700, which increases the stability of the structure and ensures the stable operation of the swing arm.

[0045] In this embodiment, a shaft hole 110 is provided on the first mounting seat 100 opposite to the first rotation assembly hole 211. After the swing arm driven shaft passes through the shaft hole 110, it is rotatably connected within the first rotation assembly hole 211. The stable mounting seat 220 is arranged on one side of the first mounting seat 100 close to the second mounting seat 300 through a detachable connecting member. The shaft hole 110 and the swing arm driven shaft 700 are in clearance fit. Specifically, the detachable connecting member includes a first connecting hole 410 penetrating through opposite ends of the stable mounting seat 220, a second connecting hole 420 arranged around the shaft hole 110 of the first mounting seat 100 and matching with the first connecting hole 410, and a connecting column 430 that can be inserted into the first connecting hole 410 and the second connecting hole 420 to connect the stable mounting seat 220 and the first mounting seat 100.

The stable mounting seat 220 and the first mounting seat 100 are detachably connected through the cooperation of the clamping head and the clamping seat.

[0046] Refer to Figures 2 - 4 , in this embodiment, the outer sidewall of the first rotation connecting member 210 is spherical. It can be understood that the spherical outer sidewall of the first rotation connecting member 210 contacts the hole wall of the second rotation assembly hole 221, enabling the first rotation connecting member 210 to tilt and rotate within a certain angle range around its central axis, thereby achieving the purpose of alignment.

[0047] In this embodiment, it includes a mounting base plate 500. The first mounting seat 100 and the second mounting seat 300 are both arranged on the top of the mounting base plate 500.

Optionally, the first mounting seat 100 and the second mounting seat 300 are formed by bending the mounting base plate 500 upward. An abutting hole is provided on the fixing seat 510. The torsion arm 610 of the torsion spring 600 passes through and abuts in the abutting hole. When the driving assembly drives the swing arm main body to lock the parking space, the driving assembly will drive the swing arm driving shaft to drive the swing arm main body and the swing arm driven shaft to rotate synchronously. At this time, the torsional moment of the torsion spring 600 acts on the swing arm driven shaft to cooperate with the driving assembly to quickly erect the swing arm main body to achieve the purpose of locking the parking space.
