However, when unmanned guided vehicles are transporting goods of different weights, the conventional spring-adjusted chassis used by unmanned guided vehicles has limited adaptability to the ground and is difficult to reconcile the light weight of the unmanned guided vehicle with the heavy load. It is easy for the unmanned guided vehicle to tilt when it is empty and slip due to insufficient driving force for heavy loads. Summary of the invention

[0013] In a specific implementation scheme, the first adjustment assembly and the second adjustment assembly are symmetrical with respect to the axis of rotation of the first chassis and the second chassis, thereby improving the force effect of the first chassis and the second chassis.

[0014] In a specific implementation scheme, the distance between the first adjustment component and the second adjustment component gradually decreases as the weight supported by the support platform increases, thereby adjusting the force between the two chassis to improve the stability of the universal platform.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] First, the application scenario of the universal platform provided in the embodiment of the present application is explained. The universal platform provided in the embodiment of the present application is applied to the transshipment of goods in the logistics warehouse. When in use, the goods are placed on the universal platform, and the goods are transshipped from location A to location B through the universal platform, wherein location A and location B represent two different locations in the logistics warehouse, such as a storage point, a loading and unloading point, etc. The universal platform may be affected by the ups and downs of the ground during transshipment. In order to better adapt to the ups and downs of the ground and improve the force of the universal platform, the embodiment of the present application provides a universal platform. The following is a detailed description of it in conjunction with specific drawings and embodiments.

[0033] refer to Figure 1 and Figure 2 , Figure 1 A side view of a universal platform provided by an embodiment of the present application is shown. Figure 2 The example shows an exploded schematic diagram of a universal platform. The universal platform provided in the embodiment of the present application comprises two parts: a support assembly 20 and a chassis assembly 10. The support assembly 20 is used to carry goods, and the chassis assembly 10 is used to support the support assembly 20, and the chassis assembly 10 is used to walk on the ground. The two parts of the universal platform are described separately in conjunction with the accompanying drawings.

[0034] Continue to refer Figure 1 and Figure 2 The chassis assembly 10 provided in the embodiment of the present application includes two parts: a first chassis 11 and a second chassis 12. Figure 1 It can be seen that the first chassis 11 and the second chassis 12 are hingedly connected to achieve relative rotation; the first chassis 11 and the second chassis 12 can form a structure similar to a hinge. When no rotation occurs, the first chassis 11 and the second chassis 12 form a flat chassis, such as Figure 1 The first chassis 11 and the second chassis 12 rotate relative to each other, as shown in Figure 1 In the direction indicated by the double-sided arc arrow shown in the figure, the first chassis 11 and the second chassis 12 can form a "Λ" shape, and of course, they can also rotate in the opposite direction to form a V shape. Figure 2 The first chassis 11 and the second chassis 12 are both semicircular chassis. The first chassis 11 and the second chassis 12 are assembled together to form a circular chassis. The first chassis 11 and the second chassis 12 are hingedly connected to each other through a pin disposed at the opposite sides thereof. Figure 2 As shown in the figure, the first chassis 11 has a recessed notch (not shown in the figure), and the second chassis 12 has a protrusion (not shown in the figure) inserted into the notch. The pin passes through the side wall and the protrusion of the notch to splice the first chassis 11 and the second chassis 12 together.

[0035] It should be understood that in the embodiment of the present application, the specific shapes of the first chassis 11 and the second chassis 12 are not specifically limited. Figure 2 The shapes of the first chassis 11 and the second chassis 12 are only a specific example. The first chassis 11 and the second chassis 12 provided in the embodiment of the present application may also adopt different shapes such as rectangle, triangle, etc.

[0036] Continue to refer Figure 1 and Figure 2 The chassis assembly 10 also includes a driving wheel assembly 15. The driving wheel assembly 15 is a common driving wheel assembly in the prior art and is used to drive the entire universal platform to move. The specific structure thereof will not be described in detail herein. Figure 2 The middle driving wheel assembly 15 is arranged on the side of the second chassis 12 close to the first chassis 11, that is, the driving wheel assembly 15 can only be arranged in the middle position of the chassis formed after splicing. Figure 2 In addition to the manner shown, the driving wheel assembly 15 can also be arranged on the first chassis 11, which is not specifically limited in the embodiment of the present application.

[0037] Continue to refer Figure 1 and Figure 2 The chassis assembly 10 further includes a universal wheel assembly for supporting the chassis assembly 10. Figure 1 As shown in FIG. 1 , a first universal wheel assembly 13 is disposed on the first chassis 11, and a second universal wheel assembly 14 is disposed on the second chassis 12; and the first universal wheel assembly 13 and the second universal wheel assembly 14 are arranged on both sides of the driving wheel assembly 15. Figure 1 It can be seen that the first universal wheel assembly 13 is arranged at one end of the first chassis 11 away from the second chassis 12, the second universal wheel assembly 14 is arranged at one end of the second chassis 12 away from the first chassis 11, and the first universal wheel assembly 13, the driving wheel assembly 15 and the second universal wheel assembly 14 realize the support of the chassis assembly 10. Among them, the first universal wheel assembly 13 and the second universal wheel assembly 14 have the same structure, and the second universal wheel assembly 14 is taken as an example for description below.

[0038] Continue to refer Figure 2The second universal wheel assembly 14 includes a second balance beam 142 and two second universal wheels 141 rotatably connected to both ends of the second balance beam 142; wherein, two symmetrical pins 143 are arranged on the second chassis 12, the second balance beam 142 is inserted between the two pins 143, and is rotatably connected to the pins 143 through a rotating shaft, so as to realize the rotatable connection between the second balance beam 142 and the second chassis 12; the two second universal wheels 141 are symmetrically arranged on both sides of the rotating shaft, and are rotatably connected to the second balance beam 142. When walking on an uneven road surface, the second balance beam 142 can swing around the rotating shaft like a seesaw, which can ensure that the two second universal wheels 141 can maintain a contact effect with the ground. The contact effect between the chassis assembly 10 and the ground is enhanced.

[0039] Continue to refer Figure 2 The first universal wheel assembly includes a first balance beam and two first universal wheels rotatably connected to both ends of the first balance beam. The specific structure thereof can refer to the specific description of the second universal wheel assembly above, which will not be repeated here.

[0040] Continue to refer Figure 1 When the first universal wheel assembly 13 and the second universal wheel assembly 14 are specifically set, the first universal wheel assembly 13 and the second universal wheel assembly 14 are symmetrically arranged relative to the driving wheel assembly 15 to improve the stress condition of the chassis assembly 10. However, in the embodiment of the present application, it is not limited that the first universal wheel assembly 13 and the second universal wheel assembly 14 must be symmetrical, and they can also be arranged in an asymmetrical manner, as long as they can improve the force balance of the chassis assembly 10.

[0041] Continue to refer Figure 1 and Figure 2 The support assembly 20 provided in the embodiment of the present application includes two parts: a support platform 21 and an adjustment assembly for connecting the support platform 21 and the chassis assembly 10. First, the support platform 21 can be used to carry goods, or combined with external equipment (such as rollers, belt conveyors, lifting assemblies, mechanical arms and other external modules) to form a stable platform with strong adaptability to the ground. Figure 2 The support platform 21 is a square platform, and the center of the support platform 21 is coaxial with the center of the chassis formed by splicing the first chassis 11 and the second chassis 12. The axis is approximately perpendicular to the surface of the support platform 21 used to support the goods. Of course, it should be understood that the above-mentioned approximately perpendicular refers to the angle between the axis and the surface of the support platform 21 within the range of 85° to 95° within the allowable range of assembly error. The size of the support platform 21 is not limited here, that is, the size of the support platform 21 can be greater than, equal to, or less than the size of the spliced ​​chassis. Figure 2 The size of the support platform 21 shown in the example is smaller than the size of the chassis formed by splicing. Figure 2 In addition to the square shown in the example, other shapes such as circle, oval, rectangle, etc. can also be used. It is only necessary to ensure that the center of the support platform 21 is coaxial with the center of the assembled chassis to ensure the stability of the center of gravity of the entire universal platform.

[0042] Continue to refer Figure 1 and Figure 2 The adjustment component is used to connect the support platform 21 with the first chassis 11 and the second chassis 12. In the embodiment of the present application, the adjustment component is used to connect the support platform 21 with the first chassis 11 and the second chassis 12 to achieve the effect of relative rotation between the support platform 21 and the chassis component 10. The adjustment component can be implemented in different ways. Figure 1 and Figure 2 As shown in , the adjustment component is a connecting rod component, and the connecting rod component and the support platform 21 form a four-bar linkage. Specifically, the adjustment component includes a first adjustment component 23 and a second adjustment component 22; wherein the number of the first adjustment component 23 and the number of the second adjustment component 22 are two, as shown in FIG. Figure 2 As shown in , two first adjustment components 23 are arranged on the first chassis 11, and the arrangement direction of the two first adjustment components 23 is parallel or approximately parallel to the rotation axis (the rotation axis that the first chassis 11 and the second chassis 12 are rotatably connected), and two second adjustment components 22 are arranged on the second chassis 12, and the arrangement direction of the two second adjustment components 22 is parallel or approximately parallel to the rotation axis. When the first adjustment components 23 and the second adjustment components 22 are arranged, the heights of the first adjustment components 23 and the second adjustment components 22 are equal, as shown in FIG. Figure 1 As shown in , the supporting platform 21 and the chassis assembly 10 (when the first chassis 11 and the second chassis 12 do not rotate relative to each other) can remain parallel.

[0043] The first adjustment assembly 23 and the second adjustment assembly 22 are described below. For ease of understanding, it is first explained that in the hinges involved in the first adjustment assembly 23 and the second adjustment assembly 22, the rotation axes around which the components rotate are parallel or approximately parallel to the rotation axes around which the first chassis 11 and the second chassis 12 rotate, wherein approximately parallel refers to parallelism recognized within the range of assembly error, such as an angle of -5° to +5° between the two rotation axes.

[0044] Continue to refer Figure 1 and Figure 2 First, the first adjustment component 23 is described. The first adjustment component 23 is located between the rotating shaft (the rotating shaft that the first chassis 11 and the second chassis 12 are rotatably connected to) and the first universal wheel component 13. When the force of the weight of the cargo carried by the support platform 21 is transmitted to the first chassis 11 through the first adjustment component 23, the force of the first chassis 11 can be equivalent to the force of the rod, such as Figure 3As shown in FIG. 1 , F1 is the force applied by the first adjustment assembly 23 to the first chassis 11, F2 is the force applied by the shaft to the first chassis 11, and F3 is the force applied by the first universal wheel assembly 13 to the first chassis 11. Figure 3 It can be seen that when the first adjustment component 23 applies force F1 to the first chassis 11, the force can be divided into force F2 applied to the rotating shaft (i.e., force applied to the driving wheel assembly 15) and force F3 applied to the first universal wheel assembly 13, so that the driving wheel assembly 15 and the first universal wheel assembly 13 can share the force to avoid excessive force on one of them. The first universal wheel assembly 13 can be kept in contact with the ground through the rotating shaft to avoid slipping.

[0045] Continue to refer Figure 2 The first adjustment component 23 includes a first support column 232 arranged on the first chassis 11, and a second support column 231 arranged on the support platform 21, and the first support column 232 is hinged to the second support column 231. The first support column 232 and the second support column 231 are both pins, and are fixedly connected to the support platform 21 and the first chassis 11 respectively. If the first support column 232 and the first chassis 11 are an integral structure, they can be integrally formed by casting or die-casting; or the first support column 232 and the first chassis 11 are connected together by connecting parts (bolts or screws), welding, or riveting. The connection method between the second support column 231 and the support platform 21 is similar and will not be repeated here. Figure 1 It can be seen that the length of the first support column 232 is greater than the length of the second support column 231, but in the embodiment of the present application, it is not limited to the first support column 232 being greater than the second support column 231. The first support column 232 may also be equal to or less than the second support column 231. The specific setting method can be limited as needed.

[0046] Continue to refer Figure 1 and Figure 2 The second adjustment assembly 22 is located between the rotating shaft (the rotating shaft that the first chassis 11 and the second chassis 12 are rotatably connected to) and the second universal wheel assembly 14. When the force of the weight of the cargo carried by the support platform 21 is transmitted to the first chassis 11 through the second adjustment assembly 22, the force on the second chassis 12 can be equivalent to the force on the rod. The force analysis can refer to Figure 3Regarding the stress of the first chassis 11, when the second adjustment component 22 is set between the rotating shaft and the second universal wheel component 14, the second universal wheel component 14 and the driving wheel component 15 can be kept in contact with the ground to avoid slipping. At the same time, it can be seen from the stress of the first adjustment component 23 and the second adjustment component 22 on the chassis component 10 that when the support platform 21 is stressed, the support platform 21 can distribute the force to the first universal wheel component 13, the driving wheel component 15 and the second universal wheel component 14 through the first adjustment component 23 and the second adjustment component 22, thereby achieving the effect of keeping several wheel groups in contact with the ground to avoid slipping, and also avoiding the situation where a single wheel group is subjected to excessive stress. At the same time, by articulating the first chassis 11 and the second chassis 12, the situation of the chassis component 10 tilting is avoided, which greatly improves the stress and ground adaptation effect of the universal platform during operation.

[0047] Continue to refer Figure 1 and Figure 2 As shown in , the second adjustment component 22 includes a third support column 223 provided on the second chassis 12, a fourth support column 221 provided on the support platform 21, and a fifth support column 222, wherein the third support column 223 and the fourth support column 221 are pins, which can be fixedly connected to the second chassis 12 and the support platform 21 respectively by integral molding or welding, and the specific fixed connection method can refer to the fixed connection method of the first adjustment component 23 with the first chassis 11 and the support platform 21. The fifth support column 222 is a rod-shaped structure, and the third support column 223 and the fourth support column 221 are hingedly connected to the two ends of the fifth support column 222 one by one.

[0048] Continue to refer Figure 1 When the first adjustment component 23 and the second adjustment component 22 adopt a connecting rod mechanism, when the ground undulates, the first chassis 11 and the second chassis 12 will rotate relative to each other, and when the first chassis 11 and the second chassis 12 rotate relative to each other, the fifth support column 222 will be driven to rotate accordingly, and the second support column 231 and the first support column 232 will also rotate relative to each other, so as to reduce the changes transmitted to the support platform 21 when the first chassis 11 and the second chassis 12 rotate relative to each other, achieve a shock absorbing effect, reduce the impact on the support platform 21, and maintain the stability of the support platform 21 as much as possible.

[0049] Continue to refer Figure 1 and Figure 2 When the first adjustment component 23 and the second adjustment component 22 are specifically set, the first adjustment component 23 and the second adjustment component 22 are symmetrical with respect to the axis of rotation of the first chassis 11 and the second chassis 12, thereby improving the force effect of the first chassis 11 and the second chassis 12 and improving the stability of the universal platform.

[0050] When the universal platform transports goods, due to the different weights of the goods, its center of gravity will also change. For example, when the weight of the goods is relatively large and the center of gravity is relatively high, or when the weight of the goods is relatively light and the center of gravity is relatively low, the overall stability of the universal platform when transporting goods will be affected. In order to improve the stability when transporting goods. The universal platform provided in the embodiment of the present application can adjust the spacing between the first adjustment component 23 and the second adjustment component 22 as needed to improve the stability of the universal platform. Exemplarily, when the weight of the goods is relatively large, the center of gravity of the goods is relatively low, the first adjustment component 23 and the second adjustment component 22 are both close to the drive wheel, and the spacing between the first adjustment component 23 and the second adjustment component 22 is small, so that the load-bearing ratio of the drive wheel component 15 is increased, and the driving capacity is better; the weight of the goods is relatively light, and the center of gravity of the goods is relatively high, the first adjustment component 23 and the second adjustment component 22 are both moved in the direction away from the drive wheel component 15, and the spacing between the first adjustment component 23 and the second adjustment component 22 is large, so that the stability of the universal platform is better and the risk of overturning of the whole vehicle is reduced. That is, the distance between the first adjustment component 23 and the second adjustment component 22 gradually decreases as the weight supported by the support platform 21 increases. When transporting goods of different weights, a matching universal platform can be selected according to the above description.

[0051] In addition, the first adjustment component 23 and the second adjustment component 22 provided in the embodiment of the present application can also be adjusted, such as the position of the first adjustment component 23 is adjustable, and the position of the second adjustment component 22 is fixed; or the position of the second adjustment component 22 is adjustable, and the position of the first adjustment component 23 is fixed; or the positions of the first adjustment component 23 and the second adjustment component 22 are both adjustable. Figure 1 and Figure 2 In the embodiment, a solution in which the positions of the first adjustment component 23 and the second adjustment component 22 are fixed is exemplified, and therefore, only the manner in which the positions of the first adjustment component 23 and the second adjustment component 22 can be adjusted is described below.

[0052] When the position of the first adjustment component 23 is adjustable, different methods may be used. For example, Figure 4 As shown in , when a sliding manner is adopted, the first support column 232 of the first adjustment component 23 can slide relative to the support platform 21 and can be locked in a set position; the second support column 231 of the first adjustment component 23 can slide relative to the first chassis 11 and can be locked in a set position. It is possible to respectively set slide rails 30 on the first chassis 11 and the support platform 21, and the first support column 232 and the second support column 231 can be slidably assembled on the slide rails 30, and the first support column 232 and the second support column 231 can be locked by a locking bolt (not shown in the figure). It should be immediately noted that the locking bolt is a common locking method in the prior art, so its specific structure will not be described in detail here. Or as Figure 5As shown in , the first chassis 11 is provided with a plurality of first assembly holes 41 that match the first support column 232, and the plurality of first assembly holes 41 are arranged in a single row along the arrangement direction of the first chassis 11 and the second chassis 12; the support platform 21 is provided with a plurality of second assembly holes 42 that match the second support column 231, and the plurality of second assembly holes 42 are arranged one-to-one with the plurality of first assembly holes 41. By inserting the first support column 232 and the second support column 231 into different assembly holes respectively, the position of the first adjustment component 23 is adjusted. Among them, the first support column 232 and the first assembly hole 41 can be connected by common fixed connection methods such as threaded connection, clamping or interference fit, and these specific matching methods will not be described in detail here.

[0053] Of course, the second adjustment component 22 can also be implemented in the above manner. For example, the third support column 223 of the second adjustment component 22 can slide relative to the support platform 21 and can be locked in a set position; the fourth support column 221 of the second adjustment component 22 can slide relative to the second chassis 12 and can be locked in a set position. The relative position relationship between the first support component 20 and the second support component 20 is adjusted by sliding. The specific sliding method can refer to the sliding method of the first adjustment component 23 mentioned above, which will not be repeated here. Or the second chassis 12 is provided with a plurality of third assembly holes 43 that cooperate with the third support column 223, and the plurality of third assembly holes 43 are arranged in a single row along the arrangement direction of the first chassis 11 and the second chassis 12; the support platform 21 is provided with a plurality of fourth assembly holes 44 that cooperate with the fourth support column 221, and the plurality of fourth assembly holes 44 are arranged one by one with the plurality of third assembly holes 43. The specific connection method can refer to the above description of the first adjustment component 23, which will not be repeated here.

[0054] By the above Figure 4 and Figure 5 As can be seen from the description, the spacing between the first adjustment component 23 and the second adjustment component 22 can be adjusted in different ways. When matching different goods, the spacing between the first adjustment component 23 and the second adjustment component 22 can be adjusted as needed, thereby improving the applicability of the universal platform.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
