The invention discloses an automobile maintenance bracket, the structure of which comprises: a new type limiting device, a movable plate, a main bracket, a lifting rod, a hydraulic roof, a support plate, a fixed bottom plate, an electric box, a mounting seat, a sliding plate, a baffle, a connection Plate, strong spring, limiting plate, the sliding plate is located on the outer side of the connecting plate and is an integrated structure with the connecting plate, the baffle is located on the upper surface of the sliding plate and is fixedly connected with the sliding plate, and the limiting plate is located on the upper surface of the connecting plate The right side is movably connected by loose-leaf, the strong spring is located on the upper surface of the connecting plate and is fixedly connected with the connecting plate, and the sliding plate is movably connected with the main bracket. The maintenance bracket can prevent the car from slipping backward during the maintenance process, so that the personal safety of the maintenance personnel will not be threatened.

The invention discloses a shopping cart which comprises a cart frame, an object storage basket, front wheels, rear wheels and a brake device. The object storage basket is installed on the cart frame, the two front wheels and the two rear wheels are connected on two sides of the cart frame, and the two rear wheels are connected through a rotating shaft fixed on the cart frame. Each rear wheel comprises a tripod and rollers, three legs of the tripod are connected with the rollers which are connected with the brake device, the brake device is installed on the tripods and the cart frame, and each tripod sleeves the rotating shaft and can rotate around the rotating shaft. The shopping cart has functions of braking and folding, and is simple in operation and safe in use. The shopping cart can cross over obstacles like steps even in the braking process, and the storage space is effectively saved when the shopping cart is folded.

A slippage preventing system for vehicular hill starting is mounted on an axle of driven wheels by a one-way brake starter through a support. The one-way brake starter comprises a ratchet wheel, a flywheel in a pawl structure or a ratchet-gear wheel in a shell, a rack push rod meshed with the flywheel in a pawl structure or the ratchet-gear wheel and a return spring on the rack push rod and a truckle, mounted on a same shaft with the flywheel or the ratchet-gear wheel, outside the shell. The slippage preventing system is controlled by a hydraulic passage or an inhaul cable connected with the same and disposed in a cab. During hill starting, the truckle is combined with a rim part of a brake disk or a hub, when slippage occurs, the rotating rim of the brake disk or the hub drives the truckle outside the shell and the flywheel or the ratchet-gear wheel in the shell to poke the rack push rod outwardly so as to compress an auxiliary brake pump piston at the position, braking is achieved by the aid of the hydraulic passage connected with the auxiliary brake pump and a driven wheel brake caliper or an auxiliary brake caliper, and braking stops when a vehicle advances.

The invention relates to the technical field of automobile braking, in particular to a vehicle driving safety control system. The system comprises a controller, a hill-start backward sliding prevention control system, a driving emergency brake control system, a reverse tooth gear shaft sleeving an automobile transmission shaft and reverse teeth on the reverse tooth gear shaft, wherein the hill-start backward sliding prevention control system comprises a backward sliding prevention switch, a first-gear switch, a gradient sensor and a backward sliding prevention electromagnetic valve; when the condition is met, the controller electrifies the electromagnetic valve, armature pusher rods moves downwards to press a lock rod to press against the reverse teeth and prevent the transmission shaft from rotating anticlockwise; the driving emergency brake control system comprises a pedal position sensor, a pusher rod extreme position switch, a reverse switch, a wheel speed sensor and an emergency brake electromagnetic valve; during electrification under the condition, the two armature pusher rods press the reverse teeth from the two sides to prevent the transmission shaft from rotating clockwise and anticlockwise. The vehicle driving safety control system has functions of prevention of a vehicle from sliding backwards and automatic emergency braking, so that the safety of the vehicle can be improved, and vehicle accidents are effectively avoided.

The invention designs an auxiliary device for vehicle uphill and downhill. The auxiliary device for the vehicle uphill and downhill comprises roller devices, a damping wheel, a position and speed detection device, a solar panel, an electric generator device, a storage battery, a LCD display screen, a controller module. The roller devices, the damping wheel, the position and speed detection device,the solar panel, the electric generator device, the storage battery and the LCD display screen are all connected with the controller module. When a vehicle passes an uphill road, the roller devices provide the forward power for the vehicle by rotating, and the vehicle can be prevented from slipping back. When the vehicle passes through the roller devices, arranged side by side, on a downhill roadsurface, the position and speed information of the vehicle is detected by the position and speed detection device, the controller displays the speed on the LCD display screen; the greater the speed,the greater the damping of the damping wheel on the roller devices; and if the vehicle speed exceeds a certain threshold, the auxiliary device is simple in structure design, is more effective than a general uphill and downhill auxiliary device, and the effect is better.

The invention relates to a roller-shaft-type car intelligent uphill and downhill auxiliary apparatus. The roller-shaft-type car intelligent uphill and downhill auxiliary apparatus comprises a roller shaft apparatus, a damping wheel, a position and speed detection apparatus, a solar panel, a power generator apparatus, a storage battery, an LCD display screen and a controller module, wherein the roller shaft apparatus, the damping wheel, the position and speed detection apparatus, the solar panel, the power generator apparatus, the storage battery and the LCD display screen are connected with the controller module, when a vehicle passes by an uphill pavement, the roller shaft provides the forwarding power to the vehicle by virtue of rotation, and an effect for preventing the backward slippage of the vehicle can be realized; and when the vehicle passes by a side-by-side roller shaft apparatus of a downhill pavement, the position and speed information of the vehicle at the moment can be detected by virtue of the position and speed detection apparatus, the controller displays the speed on the LCD display screen, the greater the vehicle speed is, the greater the damping of the damping wheel on the roller shaft apparatus is, if the vehicle speed is greater than a given threshold value, the structural design is simple, the auxiliary apparatus is more effective than the ordinary uphilland downhill auxiliary apparatus, and the action effect is better.
