DETAILED DESCRIPTION
[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0032] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 The utility model provides a vehicle mover for testing vehicle transfer, comprising: a vehicle frame assembly 100; two wingspans 300, respectively arranged on both sides of the vehicle frame assembly 100, the wingspans 300 comprising a wingspan frame 301, a first swing arm 302, a retaining spring 305, and a second swing arm 306, the first swing arm 302 being rotatably connected to the wingspan frame 301 via a first rotating shaft 303, one end of the first swing arm 302 being rotatably connected to a first support 304, and the other end being configured as a toggle portion 3021, the two ends of the retaining spring 305 being rotatably connected to the wingspan frame 301 The ends are respectively connected to the wing frame 301 and the first swing arm 302, the second swing arm 306 is rotatably connected to the wing frame 301 through the second rotating shaft 307, the toggle portion 3021 is in contact with the second swing arm 306, and a second pillar 308 is provided at one end of the second swing arm 306; wherein, when the first pillar 304 is pressed downward, the first swing arm 302 swings, the toggle portion 3021 drives the second swing arm 306 to swing, the second pillar 308 to tilt upward, and the retaining spring 305 to undergo elastic deformation.
[0033] Specifically, a plurality of electric wheels are provided at the bottom of the frame assembly 100, and a controller assembly 200 is installed on the upper part of the frame assembly 100. The controller assembly 200 is used to control the movement of the electric wheels and the swing of the swing arm 400; the wingspan frame 301 is fixed to the side of the frame assembly 100, and the first rotating shaft 303, the first pillar 304, the second rotating shaft 307, the second pillar 308, the first roller 309 and the second roller 310 are respectively parallel.
[0034] When using, attach Figure 4 Taking the position relationship in as an example, when the wheel travels to the wingspan 300, the wheel first contacts the first pillar 304. As the wheel moves, the wheel presses down the first pillar 304, driving the first swing arm 302 to rotate counterclockwise around the first rotation axis 303, the tension of the retaining spring 305 increases, the toggle part 3021 pushes up the second swing arm 306, and the second swing arm 306 rotates clockwise around the second rotation axis 307, so that the second pillar 308 is tilted upward, and the wheel stops when it abuts the second pillar 308, limiting the wheel; when the wheel is unloaded, the pressure on the first pillar 304 is released, the first swing arm 302 is reset under the elastic force of the retaining spring 305, and the second swing arm 306 is reset as the toggle part 3021 falls; when the wingspan 300 is used alone, the retaining spring 305 plays a reset role to prevent components from moving and prepare for moving the vehicle.
[0035] In this application, please see the attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 A first roller 309 is also installed on the wingspan frame 301, between the first support 304 and the second support 308. The first roller 309 is higher than the first support 304. When the first support 304 is reset under the elastic force of the retaining spring 305, the first swing arm 302 contacts the bottom of the first roller 309. When the wheel reaches the wingspan 300, as the wheel presses down on the first support 304, the first swing arm 302 separates from the first roller 309, and the first roller 309 serves as support for the wheel. When the wheel is unloaded, the pressure on the first support 304 is released, and the first swing arm 302 is reset under the elastic force of the retaining spring 305. At this time, the first swing arm 302 rotates clockwise until it contacts the first roller 309, limiting the swing amplitude of the first swing arm 302 and preventing it from swinging too far due to inertia and hitting the second swing arm 306.
[0036] In this application, please see the attached Figure 2 , Attachment Figure 3 , Attachment Figure 4A second roller 310 is provided on the wingspan frame 301, on the side of the first support 304 away from the second support 308. The second roller 310 is lower than the first support 304. Since the second roller 310 is at the lowest position, when the wheel reaches the wingspan 300, it first contacts the second roller 310, providing a transition for the wheel during travel.
[0037] In this application, please see the attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 The surface of the second pillar 309 is provided with a rubber layer. The rubber layer can increase the lateral friction of the wheel and prevent the wheel from sliding laterally.
[0038] Please see the attached Figure 5 and attached Figure 6 A swing arm 400 is rotatably provided at the end of the frame assembly 100, and the swing arm 400 includes a swing arm frame 401, a load-bearing shaft 402, a third roller 403, a rotation limit frame 404 and a torsion spring 405; the load-bearing shaft 402 is arranged on the swing arm frame 401, and the third roller 403 is sleeved on the load-bearing shaft 402, and the rotation limit frame 404 is located on one side of the third roller 403, and its two ends extend to the two ends of the third roller 403 respectively, and the torsion spring 405 is sleeved on the load-bearing shaft 402, and the two legs of the torsion spring 405 are respectively fixed to the load-bearing shaft 402 and the rotation limit frame 404.
[0039] Specifically, a rotating connection part 4011 is provided on the swing arm frame 401, and the axis of the rotating connection part 4011 is perpendicular to the axis of the load-bearing shaft 402; the rotating connection part 4011 realizes the rotation connection between the frame assembly 100 and the swing arm frame 401, and the rotation of the swing arm frame 401 is realized by installing a rotating driving part such as a motor or a rotating cylinder, thereby restricting the other side of the wheel, so that the swing arm 400 cooperates with the wingspan 300 to complete the positioning and clamping of both sides of the wheel.
[0040] During actual use, when the swing arm frame 401 rotates to the other side of the wheel, the wheel passes over the rotating connection part 4011 of the swing arm frame 401 and rotates the swing arm frame 401 until it is parallel to the first pillar 304. After the rotation limit frame 404 contacts the wheel, it rotates around the load-bearing axis 402 under the action of the wheel pressure. At the same time, the torque of the torsion spring 405 increases, so that both sides of the wheel are subjected to elastic force toward the center of the wheel, clamping both sides of the wheel, making the wheel positioning more stable.
[0041] In general, adding a torsion spring to the swing arm structure, on the one hand, cooperates with the retaining spring to make both sides of the wheel subject to elastic force toward the center of the wheel, thereby clamping both sides of the wheel and making the wheel clamping more stable; on the other hand, cooperates with the retaining spring to avoid rigid contact between the two sides of the wheel, which is beneficial to protecting the wheel structure.
[0042] In addition, in order to facilitate the state in which the swing arm frame 401 is perpendicular to the first pillar 304, that is, to avoid the travel path of the wheel, a pin shaft 406 is provided at the end of the swing arm frame 401; the pin shaft 406 is used to fix the swing arm frame 401 to the frame assembly 100 to prevent the swing arm 400 from shaking.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
