Description

Tire bracket with gradually-changed wheel diameter, fork arm with tire bracket and parking robot with tire bracket
Technical Field
The invention belongs to the technical field of intelligent parking, and relates to an intelligent parking robot, in particular to a tire bracket with gradually changed wheel diameter, a fork arm with the tire bracket and a parking robot.
Background
With the increase of the popularity of household vehicles, the number of vehicles in cities is increased, but the number of parking spaces in the cities is limited, and the urban land is more and more scarce, so that the parking is increasingly tense. Along with the improvement of living standard of people, the demand for a parking mode with small floor area and high automation level is gradually increased. Adopt intelligent parking robot to carry the parking stall with the vehicle, replace the manual work to look for the parking stall and park, can effectively increase the parking number under the same area, and also can not appear the condition of jam in the parking lot in parking or the peak hour of getting the car. Such a parking method and an intelligent parking robot are expected and favored by many people. Among them, the most important device is an intelligent parking robot.
At present, various intelligent parking robots with different structures are available in the market, wherein the parking robot which adopts a fork arm to clamp a vehicle tire to enable a vehicle to be separated from the ground has wide application prospect due to the advantages of small size, flexible movement and no need of site transformation or large-scale equipment construction. After the fork arm is in contact with the tire of the vehicle, the parking robot applies horizontal extrusion force to the tire to enable the fork arm and the tire to move relatively, so that the tread of the tire is pressed on the upper surface of the fork arm, namely the fork arm supports the tire, and the effect of lifting the vehicle is achieved.
However, in use, the fork arms adopted on the existing parking robot find that the common fork arms need larger force to lift the vehicle, even can not lift some vehicles with larger front and rear counterweight differences or heavier vehicles, and meanwhile, the tire clamping and tire burst possibility exists. This is because there is friction between the yoke and the tire and there is a significant height difference between the yoke and the ground. The tire needs to overcome the friction between the yoke and the tire and to overcome the height difference between the yoke and the ground so as to press on the yoke. As the weight of the vehicle increases, the greater the pressing force required for the process of lifting the vehicle. When the required squeezing force exceeds the maximum force that the drive means can provide, the yoke cannot lift the vehicle. Meanwhile, as the pressing force increases, the possibility of pinching the tire to blow out also increases.
Disclosure of Invention
In view of the technical problems in the prior art, the invention aims to design a fork arm for a parking robot and the parking robot, wherein the diameter of a wheel of a vehicle is gradually changed by rolling friction, aiming at the problems that the fork arm for the existing parking robot is difficult to lift some vehicles which are heavier or have more different front and back weights and the risks of tire burst of tires.
The technical scheme adopted by the invention is as follows:
the invention provides a tire bracket 1 with gradually changed wheel diameter, wherein the tire bracket 1 comprises a rolling component 2, a fixed block 4 and a spring 5.
The rolling assembly 2 comprises a rolling sleeve 6, a roller shaft 7 and a shaft bracket 8. The rolling shaft sleeves 6 are sleeved on the roller shafts 7, and the roller shafts 7 are arranged in two rows or more than two rows and are arranged on the shaft bracket 8.
The axle bracket 8 comprises one transversal support 81, two first longitudinal supports 82 and one or more second longitudinal supports 83. The lateral bracket 81 is located at the rear side of the rolling assembly 2. All of the first and second longitudinal supports 82, 83 are parallel to each other. The first longitudinal support 82 is two sheet structures which are rotatably connected, namely a first rear support 84 and a front support 85, and the second longitudinal support 83 is two sheet structures which are rotatably connected, namely a second rear support 86 and a front support 85. The first rear brackets 84 are located at the left and right sides of the rolling assembly 2, and the second rear brackets 86 are located at the middle of the rolling assembly 2 and are fixedly connected to the transverse bracket 81. The roller shaft 7 is mounted between two longitudinal brackets. The diameters of all or two or more rows of the rolling bushes 6 distant from the lateral support 81 are gradually reduced as the distance from the lateral support 81 increases.
The first fixing block 41 is fixedly arranged on the outer side of the first rear side bracket 84 end of the first longitudinal bracket 82, the third fixing block 43 is fixedly arranged on the outer side of the front side bracket 85 end of the first longitudinal bracket, and the second fixing block 42 is fixedly arranged on the outer side of the position, close to the rotary connecting structure, of the front side bracket 85 of the first longitudinal bracket. One end of the leaf spring 5 is fixed to the first fixing block 41 and passes through the second fixing block 42 and the third fixing block 43.
The tire carrier 1 is fixedly connected to the yoke 3 via a first rear bracket 84.
In order to ensure the strength of the tire bracket 1, the transverse bracket 82 is a block structure, and one or more transverse fixing brackets 87 are arranged at the bottom of the first rear bracket 84 and the second rear bracket 86.
The invention also provides a fork arm 3 for the parking robot, wherein a wheel hub limiting seat is arranged at the position of the fork arm 3 corresponding to the tire, and the tire bracket 1 with the gradually changed wheel diameter is installed in the wheel hub limiting seat.
The invention also provides a parking robot, which is provided with the fork arm 3 or the tire bracket 1 with gradually changed wheel diameter for the parking robot.
The working process of the fork arm or parking robot provided with the tire bracket with the gradually changed wheel diameter is as follows: the parking robot extends the fork arm into the bottom of the vehicle and moves the fork arm to the part of the tire close to the ground; continuing to apply a squeezing force to the tire after the adaptive tire carrier on the yoke contacts the tire; under the action of the extrusion force, the part of the tire bracket close to the tire deflects to a certain degree towards the ground (because the front side bracket and the rear side bracket are rotationally connected, the front side bracket close to the tire can be pressed downwards, so that the front side bracket part rotates downwards by a certain angle); the tyre climbs onto the tyre bracket under the action of the extrusion force, and the deflection of the tyre bracket is partially recovered under the action of the spring, so that the tyre is separated from the ground to support the vehicle. In particular, since the diameter of all or several rows of said rolling sleeves remote from the transversal support gradually decreases with increasing distance from the transversal support, the height difference between the tyre carrier and the ground is further reduced, thereby further reducing the energy required to lift the vehicle off the ground.
In the working process, the tire bracket automatically deflects downwards, the height difference between the tire bracket and the ground is reduced through the deflection, the sliding friction between the tire and the tire bracket can be converted into the rolling friction through the rolling assembly, the extrusion force required by the vehicle to be separated from the ground is greatly reduced, and the risk of tire burst caused by clamping the tire is greatly reduced. When the vehicle is separated from the ground, the deflection of the tire bracket automatically restores a part under the action of the spring; when the vehicle is lowered, the deflection of the tire carrier will automatically be fully restored under the action of the spring. That is, the tire carrier of the present invention has an adaptive effect.
The invention has the following beneficial effects:
1. the tire bracket can deflect to the ground after contacting with the tire, so that the force required by the tire to climb onto the tire bracket is reduced, and a heavier vehicle or a vehicle with larger difference of front and rear counterweights can be easily lifted;
2. the tire bracket designed by the invention is a self-adaptive structure, and a driving device is not required to be additionally designed, so that the energy is saved, and the cost is reduced;
3. the diameters of all or several rows of the rolling shaft sleeves far away from the transverse support are gradually reduced along with the distance from the transverse support, so that the height difference between the tire bracket and the ground is further reduced, and the energy required for lifting the vehicle off the ground is further reduced.
