Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0022] A tire support device for an automobile, comprising:

[0023] The device body includes an adjustment plate 100, a first hydraulic rod 110 and a bottom box 111. The first hydraulic rods 110 are fixedly installed on both sides of the top of the bottom box 111, and the adjustment plate 100 is arranged at the top of the first hydraulic rod 110:

[0024] The inner wall of the top of the bottom box 111 is provided with a motor 112. The bottom of the motor 112 is installed with a connecting device 113. The inside of the connecting device 113 is provided with a vertical threaded rod 114, and the top of the vertical threaded rod 114 is connected to the inner wall of the bottom box 111 through a bearing. A threaded sleeve 115 is installed on the outside of the vertical threaded rod 114. Connecting rods 116 are fixedly installed on both sides of the threaded sleeve 115. The bottom of the connecting rod 116 is installed with a universal wheel 117. The number of universal wheels 117 is four. By turning on the motor 112, the vertical threaded rod 114 makes a lifting movement on the threaded sleeve 115, moving the universal wheel 117 outside the bottom box 111, facilitating the movement of this device to one side of the automobile tire. When fixation is required, the universal wheel 117 can be rotated into the bottom box 111 to complete the fixation. The frame for storing the universal wheel 117 at the bottom of the bottom box 111 increases the friction with the ground and prevents the displacement of this device.

[0025] Furthermore, a mounting plate 120 is provided at the top of the adjusting plate 100. On one side of the top of the mounting plate 120, a fixed clamping plate 121 is fixedly installed. On the side of the top of the mounting plate 120 away from the fixed clamping plate 121, a mounting groove 122 is formed. On one side of the inner wall of the mounting groove 122, a horizontal threaded rod 123 is installed through a bearing. An active nut 124 is arranged on the horizontal threaded rod 123. On the top of the active nut 124, an active clamping plate 125 is fixedly installed. One end of the horizontal threaded rod 123 extending outside the mounting plate 120 is provided with a handle. The clamping device on the mounting plate 120 can clamp the tire. Under the action of the second hydraulic rod 126, the mounting plate 120 can be tilted. When the vehicle is supported by the vehicle jack, the vehicle wheel axle will be tilted. The mounting plate 120 is tilted, causing the tire to be tilted. Pushing the universal wheel 117 in the bottom box 111 can then fit the tire onto the vehicle wheel axle, facilitating the installation of the tire and saving time and effort.

[0026] Furthermore, vertical guide rods 118 are fixedly installed on both sides inside the bottom box 111. Through slots are formed in the connecting rod 116, and the vertical guide rods 118 are slidably installed inside the through slots. A horizontal guide rod is arranged on one side inside the mounting groove 122.

[0027] Furthermore, shock-absorbing columns 119 are fixedly installed on both sides of the bottom of the connecting rod 116. The bottoms of the shock-absorbing columns 119 are connected to the tops of the universal wheels 117.

[0028] Furthermore, the other end of the adjusting plate 100 is rotatably connected to the mounting plate 120 through a hinge 127. A through slot is formed on one side of the adjusting plate 100, and a second hydraulic rod 126 is arranged inside the through slot. The top of the second hydraulic rod 126 is connected to the bottom of the mounting plate 120.

[0029] Furthermore, grooves are formed on the sides of the fixed clamping plate 121 and the active clamping plate 125 that face each other. A sleeve 128 is fixedly installed on the inner wall of the groove. A buffer spring 129 is fixedly installed inside the sleeve 128. A plug rod 130 is fixedly installed on the outside of the buffer spring 129. An anti-slip pad 131 is fixedly installed on the outside of the plug rod 130. This device provides a buffering effect on the tire when the fixed clamping plate 121 and the active clamping plate 125 clamp it.

[0030] Working principle: When in use, by turning on the motor 112, the vertical threaded rod 114 makes a lifting motion on the threaded sleeve 115, moving the universal wheel 117 outside the bottom box 111, facilitating the movement of the device to one side of the car tire. If fixation is required, rotate the universal wheel 117 into the bottom box 111 to complete the fixation. The frame for storing the universal wheel 117 at the bottom of the bottom box 111 increases the friction with the ground, preventing the device from shifting. The clamping device on the mounting plate 120 can clamp the tire. Under the action of the second hydraulic rod 126, the mounting plate 120 can be tilted. When the car is supported by a car jack, the car wheel axle will be tilted. The mounting plate 120 is tilted, causing the tire to be tilted. Pushing the universal wheel 117 in the bottom box 111 can then fit the tire onto the car wheel axle, facilitating the installation of the tire and saving time and effort.
