Description

Technical Field

[0001] The invention relates to an intelligent antifreeze parking lock, belonging to the technical field of parking equipment. Background Art

[0002] In recent years, with the rapid development of my country's economy, automobile consumption has gradually entered the homes of ordinary people, and

[0003] The most important factor is the surge in the number of motor vehicles. While motor vehicles bring convenience to people's travel, parking difficulties have also become a major problem.

[0004] The complication of growth. As the number of vehicles increases and parking spaces become increasingly scarce, it is inevitable that vehicles are parked randomly and fixed parking spaces are occupied. To solve this problem, parking locks are used. Parking locks are a mechanical device that prevents others from occupying your parking space and allows you to park your car whenever you want. At present, universities, enterprises, and individuals have conducted research and discussions in this regard.

[0005] At present, most of the parking locks on the market are mechanical ones, which require the owner to get out of the car and manually lift or lower it.

[0006] Lowering the bar to unlock or lock the vehicle is very inconvenient, not only wasting time, but also potentially causing traffic congestion.

[0007] It is even worse if you encounter bad weather, and there is a greater risk of freezing in the winter in the north. There are also many remote control parking locks that can control the raising or lowering of the lifting and lowering rods in the car to achieve unlocking and locking, which is more convenient. However, its structure has disadvantages, that is, it often relies on a shaft rotation to provide power to raise or lower the lifting and lowering rods. In the winter in the north, the lifting and lowering rods are likely to be frozen and cannot be lifted. Summary of the invention

[0008] The purpose of this invention is to design a parking lock controlled by a single chip microcomputer, which can realize remote control and also the lifting and lowering rod

[0009] The telescopic legs are used to avoid the situation where the lifting and lowering rods of conventional parking locks are frozen.

[0010] In order to achieve the above goals, a single-chip microcomputer is used as the control system and a screw-nut pair is designed as the actuator.

[0027] The specific technical solution of the intelligent antifreeze parking lock of the present invention is described below in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, the intelligent antifreeze parking lock of the present invention is composed of an energy and control system 4, a transmission device 5, an actuator 6 and a body.

[0029] The body consists of an outer shell 1, a bottom plate 2 and a rib plate 3. The outer shell 1 and the bottom plate 2 are fixed by four screws and six expansion screws. Six rib plates 301 and 303 are welded on the bottom plate 2 to support the outer shell. Two rib plates 302 and 304 are welded on the sliding groove 604 to support the outer shell. Three planes for installing expansion screws are made on both sides of the outer shell. A rubber ring is installed between the outer shell and the bottom plate to seal and prevent water from entering the device. The position of the outer shell relative to the bottom plate is determined by two pins. Figure 3 As shown, the energy and control system 4, the transmission device 5 and the actuator 6 are all located inside the fuselage.

[0030] like Figure 1 As shown, the energy and control system 4 includes a battery 403, a control system hardware circuit 402 and a motor 401, which are located at the square opening of the rib plate on one side of the sliding groove. The control system hardware circuit 402 is fixed on the slide groove 604 after being glue-sealed, and the battery is fixed at the square opening of the rib plate of the sliding groove.

[0031] The transmission device 5 is composed of a special bearing seat 501 and three gears 502. The special bearing seat 501 is fixed to the base plate 2 with three bolts and one screw. The motor 401 is fixed to the special bearing seat 501 with four bolts. Figure 4As shown, the intermediate idler shaft is installed in the middle hole of the bearing seat by bearing 02, nut 03 and hole elastic ring 01, and one end of the lead screw is fixed on a special bearing seat, so that the intermediate gear can transmit the motor power to the lead screw 601. The three gears 502 are fixed on the corresponding shafts with top screws.

[0032] like Figure 2 As shown, the actuator 6 is composed of a lead screw 601, a slider 602, a telescopic leg 603, a sleeve and a sliding groove 604. The sliding groove is the track of the slider, and its position is determined by two pins, and then fixed to the base plate by four bolts. The two ends of the lead screw have opposite rotation directions. The rotation of the lead screw drives the left and right sliders to move inward or outward synchronously at the same time. The upper part of the slider and the lower part of the telescopic leg are provided with holes of the same diameter. The two are connected by a sleeve, and bolts are used to prevent the sleeve from falling off. The slider must be symmetrical about the center line of the sliding groove. The other end of the lead screw is fixed by a bearing seat, and the bearings at both ends of the lead screw are fixed in one direction at both ends, such as Figure 5 shown.

[0033] The width of the telescopic leg 601 of the intelligent antifreeze parking lock is fixed, and the thickness changes sequentially along the length direction;

[0034] During the process from extension to retraction of the telescopic leg, the upper surface of the telescopic leg always keeps in contact with the shell opening.

[0035] The intelligent antifreeze parking lock has four pin holes arranged on the bottom plate, two of which are used to determine the position of the shell.

[0036] The other two are used to determine the position of the sliding slot, and then to ensure the position of the telescopic leg, so as to ensure the correct movement of the telescopic leg. The pin is an interference fit with the bottom plate, and a transition fit with the sliding slot and the shell.
