Description

Technical Field

[0001] This utility model pertains to parking devices, specifically to an auxiliary parking device for automobiles. Background Technology

[0002] With the rapid development of my country's economy and society and the continuous improvement of residents' living standards, automobiles have transformed from luxury goods to mass-market transportation tools. The number of cars in cities has exploded, while the growth rate of parking space supply is far lower than that of car ownership. Most parking spaces are designed with narrow spacing, and for conventional manual parking, especially in lateral parking scenarios, it is necessary to perform multiple cycles of "forward-backward-adjusting direction" to complete the parking. This requires a high level of driving skills, and improper operation can easily lead to accidents such as vehicle scratches and tires running over curbs. The operation takes too long, which can affect traffic flow and cause traffic jams.

[0003] To address the aforementioned issues, patent document CN102303643B discloses a lateral parking device for cars. It reveals that a hydraulic valve system controls the extension and retraction of support and telescopic hydraulic cylinders, enabling the device to be raised and lowered, thus lifting the entire car and lifting all four wheels off the ground. Finally, a motor drives the wheels to achieve lateral movement of the car, thus achieving relatively convenient parking. However, this solution has some problems in practical use: it involves multiple hydraulic cylinders, making the system structure complex and space-consuming, increasing assembly difficulty, cost, and the risk of leaks, blockages, and other malfunctions; the complex hydraulic units and multiple actuators result in significant additional weight, placing high demands on the vehicle's installation space layout. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of complex structure and large space occupation of existing car parking assistance devices, and to provide a car parking assistance device with a simplified structure and compact layout.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An auxiliary parking device for automobiles includes a load housing, a control unit, a left support frame, and a right support frame. The load housing has an inverted concave cross-section. A push rod mechanism is fixed to the inner wall of the top of the load housing. A front hinge seat and a rear hinge seat are symmetrically arranged on the front and rear inner walls of the load housing. A synchronous rod perpendicular to the front and rear inner walls of the load housing is provided. The piston rod end of the push rod mechanism is vertically fixed to the middle of the synchronous rod. The piston rod drives the synchronous rod to move up and down. The left and right support frames are mainly composed of hinges. The system consists of a front support rod connected to the front hinge seat and a rear support rod hinged to the rear hinge seat. The upper middle sections of the front and rear support rods of the left and right support frames are hinged to connecting rods. The connecting rod of the front support rod is hinged to the front end of the synchronizing rod, and the connecting rod of the rear support rod is hinged to the rear end of the synchronizing rod. A side-shifting wheel is provided between the ends of the front and rear support rods of the left and right support frames. A drive motor is fixed between the lower middle sections of the front and rear support rods of the left or right support frame. The drive motor is connected to the side-shifting wheel for transmission. The control unit controls the start and stop of the push rod mechanism and the drive motor.

[0006] Optionally, the load housing is made of channel steel, the push rod mechanism is an electric push rod, the drive motor is a hub motor, the push rod mechanism and the drive motor are powered by the vehicle power supply, and the control unit is integrated on the vehicle's main unit panel.

[0007] Optionally, several reinforcing ribs are fixed between the front and rear inner walls of the load shell.

[0008] The usage of this utility model is as follows: Taking a rear-wheel drive vehicle as an example, the push rod mechanism uses an electric push rod to fix the load shell to the rear chassis of the vehicle (the side of the rear axle, the reserved space in the middle of the frame, etc., depending on the vehicle model). The push rod mechanism and the drive motor are powered by the vehicle's power supply, and the control unit is integrated on the vehicle's main control panel. When the vehicle moves to a longitudinal parking space (the parking space is parallel to the aisle or road), the front of the vehicle enters the parking space first, the vehicle stops, the push rod mechanism is activated, the left and right support frames rise and lift the rear wheels of the vehicle, the drive motor is activated, and the vehicle moves laterally. The rear wheels of the car slowly rotate as the car moves into the parking space. The left and right support frames retract, and the rear wheels of the car touch the ground, thus completing the assisted parking in a longitudinal parking space. When the car moves to a transverse parking space (the parking space is perpendicular to the passage or road at a 90° angle), the car stops, the push rod mechanism is activated, the left and right support frames rise and lift the rear wheels of the car, the drive motor is started, the side-shifting wheels slowly rotate as the rear wheels of the car move into the parking space, the left and right support frames retract, and the rear wheels of the car touch the ground. The car reverses into the parking space, thus completing the assisted parking in a transverse parking space.

[0009] The principle of this utility model is as follows: A push rod mechanism is used to drive the left and right support frames to rise and fall and retract. A drive motor drives the side shifting wheels to move, which makes the overall structure simple and lightweight, and reduces the difficulty and cost of assembly, as well as the occurrence of failures such as leakage and blockage. The push rod mechanism is linked with the left and right support frames through a linkage mechanism, which provides high support stability. Most of these components are housed in the load shell, resulting in a compact layout and less requirement for the installation space of the car chassis.

[0010] Compared with the prior art, the present invention has at least the following advantages: the present invention has a simplified structure and a compact layout. Attached Figure Description
