Abstract
Description
Technical area
[0001] The invention relates to a mobile means of transport. State of the art
[0002] People often use wheeled vehicles to transport heavy loads. Wheels allow heavy loads to be moved quickly and easily, such as carts. With the advancement of technology, these devices are becoming increasingly automated. Therefore, some manufacturers install automation devices on the frames of mobile transport vehicles to create automated guided vehicles that can easily and automatically transport heavy loads to specified locations.
[0003] It is well known that automated guided vehicles are only suitable for driving on flat ground. When driving on uneven ground, the wheels of a conventional automated guided vehicle cannot roll smoothly on the ground, resulting in a lack of smooth driving or the vehicle losing its balance and easily tipping over, making entry and exit difficult. This easily leads to damage to the automated device and cargo. Object of the invention

The first connecting rod 21 and the second connecting rod 22 are pivotally mounted on the vehicle body 1. The slide rail unit 23 is provided on the first connecting rod 21. The slide rod unit 24 is provided on the second connecting rod 22 and slidably inserted into the slide rail unit 23. The first guide wheel 25 is provided on the first connecting rod 21. The second guide wheel 26 is provided on the second connecting rod 22. The first connecting rod 21 and the second connecting rod 22 are moved synchronously.
[0008] The two drive assemblies 3 are provided on the two support leg assemblies 2 and can be moved by them. The drive assembly 3 is provided on the first connecting rod 21. Each drive assembly 3 includes a motor 31 and a drive wheel 32. The motor 31 has a main body 311 and an output shaft 312. The main body 311 and the output shaft 312 extend along the first direction 61 and are arranged coaxially. The drive wheel 32 is connected to the output shaft 312 and is driven to rotate by the output shaft 312. The drive wheel 32 is located in a second direction 62 between the first guide wheel 25 and the second guide wheel 26, so that the mobile transport means can run stably on uneven ground surfaces. The second direction 62 is vertical to the first direction 61.
[0009] The drive gear 32, the output shaft 312, and the main body 311 are coaxially connected. When the drive assembly 3 pivots together with the first connecting rod 21, the space required in the pivoting direction can be reduced. The mass of the drive assembly 3 can be positioned closer to the rotation axis of the first connecting rod 21. The moment of inertia is low, and the pivoting direction can be changed quickly, or the pivoting amplitude can be adjusted.
[0010] The first connecting rod has a first section 211 and a second section 212, which are connected to one another. The slide rail unit 23 is provided on the first section 211, and the first guide wheel 25 is provided on the second section 212. The second connecting rod 22 has a third section 221 and a fourth section 222, which are connected to one another. The slide rod unit 24 is provided on the third section 221, and the second guide wheel 26 is provided on the fourth section 222. In the second direction 62, the length of the fourth section 222 is greater than the length of the second section 212. Viewed along the first direction 61, the first section 211 and the second section 212 form a first angle 51 that is less than 180 degrees. The third section 221 and the fourth section 222 form a second angle 52 that is less than 180 degrees. The second angle 52 is larger than the first angle 51.The first guide wheel 25 and the second guide wheel 26 can support the vehicle body 1 at different angles. Depending on the need, the side of the vehicle body 1 where the third section 221 is located can be used as the front of the vehicle, or the side of the vehicle body 1 where the fourth section 222 is located can be used as the front.
[0011] Viewed along a third direction 63, the first section 211 and the third section 221 do not extend coaxially along the second direction 62. The third direction 63 is vertical to the first direction 61 and the second direction 62. Viewed along the third direction 63, the first section 211 and the second section 212 form a third angle 53 that is less than 180 degrees. The third section 221 and the fourth section 222 form a fourth angle 54 that is less than 180 degrees. The third angle 53 is not less than the fourth angle 54. Viewed along the third direction 63, the fourth sections 222 of the two support leg assemblies 2 extend away from each other in the first direction 61. The second sections 212 of the two support leg assemblies 2 extend away from each other in the first direction 61 to lower the center of gravity and stably support the load.
[0012] The slide rail unit 23 includes a base plate 231 and two brackets 232. The first connecting rod 21 is connected to the base plate 231. The base plate 231 is connected to the motor 31.

The base plate 231 can ensure that the two brackets 232 maintain their relative position and are not easily deformed, thus increasing the stability of the connection. Each bracket 232 is provided with a guide groove 233. The two sides of the slide rod unit 24 are slidably inserted into the guide grooves 233 of the two brackets 232.
[0013] The slide rail unit 23 and the slide rod unit 24 are arranged between the drive wheel 32 and the vehicle body 1. Both the slide rail unit 23 and the slide rod unit 24 are normally at least partially covered by the drive wheel 32 in the first direction 61. The drive wheel 32 can effectively prevent foreign objects from impacting or interfering with the slide rail unit 23 and the slide rod unit 24.
[0014] The vehicle body 1 surrounds an interior space 11 and is provided with two openings 12. The two openings 12 communicate with the interior space 11. The two openings 12 are located on two sides of the vehicle body 1 in the first direction 61. The main body 311 pivotally protrudes through the opening 12 into the interior space 11.
