[0033] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] Please refer to the following Figure 1-7 The chassis 100 of the automatic guided vehicle 1000 according to an embodiment of the present invention is described.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The chassis 100 of the automated guided vehicle 1000 according to an embodiment of the present invention includes a chassis body 10 and a drive wheel assembly 20. Specifically, the drive wheel assembly 20 is connected to the chassis body 10. There are multiple drive wheel assemblies 20, that is, there are two, three, or four or more drive wheel assemblies 20, and the multiple drive wheel assemblies 20 are arranged at intervals on the chassis body 10. The drive wheel assembly 20 is used to drive the chassis body 10 to move, thereby driving the automated guided vehicle 1000 to move.

[0036] The driving wheel assembly 20 includes a first connecting beam 21, a driving wheel 22 and an auxiliary wheel 23. The first connecting beam 21 extends in a first direction (eg Figure 4 The two ends of the first connecting beam 21 (as shown in the front and rear directions) extend. Figure 4The front end and the rear end of the first beam shown in the figure are respectively provided with a first connecting portion 211 and a second connecting portion 212, and a first hinge portion 213 is provided between the first connecting portion 211 and the second connecting portion 212. The first connecting beam 21 is hinged to the chassis body 10 through the first hinge portion 213; one of the driving wheel 22 and the auxiliary wheel 23 is connected to the first connecting portion 211, and the other is connected to the second connecting portion 212. That is to say, the driving wheel 22 can be connected to the first connecting portion 211 and the auxiliary wheel 23 can be connected to the second connecting portion 212, or the auxiliary wheel 23 can be connected to the first connecting portion 211 and the driving wheel 22 can be connected to the second connecting portion 212.

[0037] For example, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, there are two driving wheel groups 20, and the two driving wheel groups 20 are arranged on the left and right sides of the chassis body 10. The first connecting beam 21 of the driving wheel group 20 extends in the front-to-back direction. The front end of the first connecting beam 21 is provided with a first connecting portion 211, and the driving wheel 22 is connected to the first connecting beam 21 through the first connecting portion 211. The rear end of the first connecting beam 21 is provided with a second connecting portion 212, and the auxiliary wheel 23 is connected to the first connecting beam 21 through the second connecting portion 212. The first connecting beam 21 is provided with a first hinge portion 213 in the middle position in the front-to-back direction, and the first connecting beam 21 is hingedly connected to the chassis body 10 through the first hinge portion 213.

[0038] When the automated guided vehicle 1000 is traveling, the driving wheel assembly 20 is in operation, and the driving wheel 22 rotates to drive the chassis body 10 to move relative to the ground. When the automated guided vehicle 1000 passes over a bumpy road surface, the first connecting beam 21 rotates relative to the chassis body 10 via the first hinge portion 213, thereby driving the driving wheel 22 and the auxiliary wheel 23 to move in the up and down directions, so that the driving wheel 22 is grounded and rotates normally, and the auxiliary wheel 23 is grounded and rotates normally in the inclined position of the pit, thereby ensuring the normal movement of the automated guided vehicle 1000.

[0039] The chassis 100 of the automatic guided vehicle 1000 of the present invention, the driving wheel 22 and the auxiliary wheel 23 are hinged to the chassis body 10 through the first connecting beam 21. When the automatic guided vehicle 1000 passes over a bumpy road surface, the driving wheel 22 and the auxiliary wheel 23 are always in contact with the ground due to the action of the first connecting beam 21, thereby ensuring that the driving wheel 22 can normally drive the automatic guided vehicle 1000 to move normally, and the auxiliary wheel 23 can normally provide support to the chassis body 10, thereby improving the stability of the movement of the automatic guided vehicle 1000, and ensuring that the automatic guided vehicle 1000 can adapt to a variety of road surfaces, effectively improving the passability of the automatic guided vehicle 1000.

[0040] In addition, the auxiliary wheel 23 cooperates with the driving wheel 22 to drive the automatic guided vehicle 1000 to move. Compared with the solution in the prior art that only provides the driving wheel 22, the auxiliary wheel 23 of the present application can provide an additional support point for the chassis body 10, thereby ensuring the smoothness of the movement, and further effectively preventing the battery equipment 2000 transported by the automatic guided vehicle 1000 from slipping off the automatic guided vehicle 1000.

[0041] According to the chassis 100 of the automatic guided vehicle 1000 of the embodiment of the present invention, the driving wheel 22 and the auxiliary wheel 23 are hinged to the chassis body 10 through the first connecting beam 21. The first connecting beam 21 can make the driving wheel 22 and the auxiliary wheel 23 always in contact with the ground, thereby improving the stability of the movement of the automatic guided vehicle 1000 and the passability of the automatic guided vehicle 1000.

[0042] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 A mounting base 11 is provided on the chassis body 10, and the mounting base 11 includes two mounting arms 111. The two mounting arms 111 are arranged at intervals, and a first connecting beam 21 is clamped between the two mounting arms 111. The first connecting beam 21 is rotatably connected to the two mounting arms 111 through a rotating shaft.

[0043] Thus, mounting arms 111 are provided on both sides of the first connecting beam 21, thereby limiting the rotational direction of the first connecting beam 21 and ensuring that the first connecting beam 21 can always push the driving wheel 22 and the auxiliary wheel 23 to the ground. At the same time, the two mounting arms 111 are connected to the first connecting beam 21 via a rotating shaft, thereby ensuring that the first connecting beam 21 can rotate relative to the mounting base 11 via the rotating shaft. In addition, this type of rotating shaft has a simple structure and is easy to install, thereby improving assembly efficiency.

[0044] For example, Figure 2 、 Figure 3 and Figure 4 As shown, a mounting base 11 is provided on the upper side of the chassis body 10, and two mounting arms 111 are provided on the upper side of the mounting base 11. The mounting arms 111 extend in the up-down direction, and the upper ends of the mounting arms 111 extend upward. The two mounting arms 111 are arranged at intervals in the left-right direction, and the first connecting beam 21 extends in the front-back direction. The first connecting beam 21 is clamped between the two mounting arms 111, and the rotating shaft passes through the mounting arms 111 and the first connecting beam 21 to hinge the first connecting beam 21 to the mounting base 11.

[0045] According to some embodiments of the present invention, referring to Figure 3 and Figure 4The drive wheel assembly 20 further includes an elastic component 24 connected between the chassis body 10 and the first connecting beam 21. The elastic component 24 exerts a force that constantly drives the drive wheel 22 downward. Thus, the elastic component 24 forces the drive wheel 22 to touch the ground, preventing the drive wheel 22 from becoming airborne when the AGV 1000 traverses a pothole, thereby ensuring that the drive wheel 22 can properly drive the AGV 1000.

[0046] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 4 , one end of the elastic component 24 (such as Figure 3 The lower end of the elastic component 24 shown in FIG) is provided on the chassis body 10, and the other end of the elastic component 24 (as shown in FIG) is provided on the chassis body 10. Figure 3 The upper end of the elastic component 24 is fixed to the first connecting beam 21 and is located between the drive wheel 22 and the first hinge portion 213. Thus, the elastic component 24 is positioned appropriately and can directly drive the first connecting beam 21 to rotate, thereby applying driving force to the drive wheel 22 through the first connecting beam 21, thereby effectively ensuring that the drive wheel 22 is always grounded.

[0047] For example, Figure 3 and Figure 4 As shown, the lower end of the elastic component 24 is provided on the chassis body 10, and the upper end of the elastic component 24 is provided on the first connecting beam 21 and is located between the driving wheel 22 and the first hinge portion 213. Preferably, the elastic component 24 is a spring, which has a simple structure and low cost, thereby facilitating mass production.

[0048] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 The auxiliary wheel 23 is connected to the second connecting portion 212, and a wheel cover 231 is provided on the first connecting beam 21. The wheel cover 231 is provided on the outside of the auxiliary wheel 23. Thus, the wheel cover 231 helps protect the mechanical structure around the auxiliary wheel 23 from external environmental influences, such as preventing dust and moisture from entering key components such as bearings, thereby extending the service life of these components.

[0049] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , including: a supporting wheel group 30, the supporting wheel group 30 is connected to the chassis body 10, and is arranged on at least one side of the chassis body 10 in the forward direction, that is, the supporting wheel group 30 can be arranged on one side of the chassis body 10 in the forward direction, and the supporting wheel group 30 can also be arranged on both sides of the chassis body 10 in the forward direction.

[0050] The supporting wheel group 30 includes a second connecting beam 31 and two supporting wheels 32. The second connecting beam 31 extends in the second direction (eg Figure 3 The left and right directions shown in FIG) extend, and both ends of the second connecting beam 31 (as shown in FIG) Figure 3 The left and right ends of the second connecting beam 31 shown in the figure are provided with two third connecting parts 311, the two supporting wheels 32 are respectively connected to the two third connecting parts 311, and a second hinge part 312 is provided between the two third connecting parts 311. The second connecting beam 31 is hinged to the chassis body 10 through the second hinge part 312, and the second direction is connected to the first direction (as shown in the figure). Figure 3 The front-to-back direction shown) intersects.

[0051] In this way, the support wheel group 30 is arranged on one side of the forward direction of the chassis body 10. When the automatic guided vehicle 1000 is traveling, it can provide support to the chassis body 10 in the forward direction, thereby effectively preventing one side of the forward direction of the chassis body 10 from contacting the ground, thereby ensuring the smooth movement of the automatic guided vehicle 1000.

[0052] Furthermore, the two support wheels 32 are hingedly connected to the chassis body 10 via a second connecting beam 31. The second connecting beam 31 rotates relative to the chassis body 10, thereby ensuring that the two support wheels 32 are always grounded, thereby ensuring that both support wheels 32 can provide support to the chassis body 10. In addition, the support wheel assembly 30 cooperates with the drive wheel assembly 20. There is a hinge point between the support wheel assembly 30 and the chassis body 10, and each of the two drive wheel assemblies 20 has an intersection with the chassis body 10, forming a three-point hinge connection with the chassis body 10, thereby ensuring that the support wheel assembly 30 and the drive wheel assembly 20 are always grounded.

[0053] For example, Figure 3 and Figure 4 As shown, the support wheel group 30 is arranged on the front side of the chassis body 10, and the first connecting beam 21 of the support wheel group 30 extends in the left and right directions. A third connecting portion 311 is respectively provided at the left and right ends of the first connecting beam 21, and the two support wheels 32 are respectively connected to the corresponding third connecting portions 311. A second hinge portion 312 is provided between the two third connecting portions 311, and the second connecting beam 31 is connected to the chassis body 10 through the second hinge portion 312.

[0054] According to the automatic guided vehicle 1000 of the second embodiment of the present invention, Figure 1 、 Figure 6 and Figure 7 , including: a chassis 100 and a tray 200 of the automatic guided vehicle 1000 of the first aspect of this embodiment, the tray 200 is fixed on the chassis 100, and the tray 200 is used to carry the battery equipment 2000.

[0055] According to the automatic guided vehicle 1000 of the embodiment of the present utility model, by setting the chassis 100 of the automatic guided vehicle 1000 of the first embodiment mentioned above, the driving wheel 22 and the auxiliary wheel 23 are hinged to the chassis body 10 through the first connecting beam 21. The first connecting beam 21 can make the driving wheel 22 and the auxiliary wheel 23 always in contact with the ground, thereby improving the stability of the movement of the automatic guided vehicle 1000 and improving the passability of the automatic guided vehicle 1000.

[0056] According to some embodiments of the present invention, referring to Figure 6 and Figure 7 The tray 200 is provided with a conveying mechanism 210, which is used to drive the battery device 2000 to move on the tray 200. Thus, the battery device 2000 can be automatically transported without manual operation, thereby improving transportation efficiency.

[0057] According to some optional embodiments of the present invention, referring to Figure 6 and Figure 7 The conveying mechanism 210 is a chain conveying mechanism, which includes a chain conveying mechanism along a first direction (such as Figure 6 The chain 2101 extends in the front-to-back direction (as shown), and the number of chain conveying mechanisms is multiple, that is, the number of chain conveying mechanisms can be two, three or four or more, and the multiple chain conveying mechanisms are arranged at intervals along the second direction, and the first direction intersects the second direction.

[0058] In this way, the chain 2101 structure can effectively avoid the chuck problem compared to the roller mechanism, thereby ensuring that the battery equipment 2000 can move normally and smoothly on the conveying mechanism 210. At the same time, multiple chain conveying mechanisms are arranged, which can contact the battery equipment 2000 at multiple positions, thereby reducing the power required for each chain 2101, and further ensuring that the chain conveying mechanism can normally push the battery equipment 2000 to move at a lower power level.

[0059] For example, Figure 6 and Figure 7 As shown, the chain conveyor mechanism includes a chain 2101 extending in the front-rear direction, and the number of the chain conveyor mechanisms is three, and the three chain conveyor mechanisms are arranged at intervals in the left-right direction. Preferably, the battery device 2000 is a carrier tray for transporting battery cells.

[0060] Furthermore, if Figure 6 and Figure 7 As shown, the three chains 2101 are synchronously driven by the same main shaft, and the motor is connected to the main shaft through the driving chain 2101, so as to ensure that the chain conveying mechanism can smoothly convey the battery equipment 2000. At the same time, it can avoid interference between the motor and the battery equipment 2000 in transportation, and can also increase the impact resistance of the chain 2101.

[0061] Furthermore, if Figure 6 and Figure 7 As shown, the tray 200 is provided with limit plates 2103 on both sides. The limit plates 2103 extend in the front-to-back direction, and the two limit plates 2103 are spaced apart in the left-to-right direction. Thus, during the movement of the battery device 2000, the limit plates 2103 can limit the battery device 2000 in the left-to-right direction, thereby preventing the battery device 2000 from moving left or right, and forcing the battery device 2000 to move only forward and backward. This prevents the battery device 2000 from sliding off the conveying mechanism 210, while ensuring that the battery device 2000 moves along the preset path.

[0062] According to some embodiments of the present invention, referring to Figure 2 、 Figure 6 and Figure 7 The conveying mechanism 210 includes: a baffle 2102, which is arranged on the chain 2101 in the first direction (such as Figure 7 The front and rear directions shown) on both sides (as shown Figure 7 The baffle 2102 is movable between a first position and a second position, wherein the upper end of the baffle 2102 is lower than the chain 2101 and the second position is higher than the chain 2101 to limit the movement of the battery device 2000.

[0063] In this way, in the first position, the battery device 2000 can be moved onto the chain 2101, thereby ensuring that the battery device 2000 can be loaded and unloaded normally. In the second position, the baffle 2102 limits the battery device 2000 in the front and rear directions, and when the automatic guided vehicle 1000 is running, it can effectively prevent the battery device 2000 from slipping off the automatic guided vehicle 1000.

[0064] For example, Figure 2 、 Figure 6 and Figure 7 As shown, the baffle 2102 is arranged on both sides of the chain 2101 in the front-to-back direction. When the baffle 2102 is in the first position, the upper edge of the baffle 2102 is lower than the chain 2101. When the baffle 2102 is in the second position, the baffle 2102 is higher than the chain 2101.

[0065] When the battery device 2000 is transported onto the conveying mechanism 210, the baffle 2102 is in the first position, and the battery device 2000 can be moved to a suitable position in the front-to-back direction. When the battery device 2000 is moved, the baffle 2102 moves from the first position to the second position, so that the baffle 2102 can limit the battery device 2000 in the front-to-back direction.

[0066] Furthermore, if Figure 1and Figure 2 As shown, the AGV 1000 includes safety edges 12, which are located on the front and rear sides of the chassis 10 and extend left and right. These contact-type safety edges 12 can detect obstacles under 50 mm in height, such as equipment feet and column bases, thereby preventing damage to the AGV 1000 from colliding with lower obstacles.

[0067] Furthermore, if Figure 1 and Figure 2 As shown, the AGV 1000 further includes a laser obstacle sensor 230 and a visual detection sensor 220. The laser obstacle sensor 230 and the visual detection sensor 220 are disposed on the pallet 200 and spaced apart in the vertical direction. The visual detection sensor 220 is disposed above the laser obstacle sensor 230. Thus, the laser obstacle sensor 230 is used to detect obstacles within a height range of 40-300 mm. By utilizing laser reflection, deceleration zones and stop zones can be set within the scanning range, thereby preventing relatively tall obstacles from colliding with the AGV 1000. The visual detection sensor 220 is used to detect areas above 300 mm, such as forklifts and rolling doors, thereby protecting the upper-level battery equipment 2000 from being hit.

[0068] Furthermore, if Figure 1 and Figure 2 As shown, the automated guided vehicle 1000 further includes a warning light 240, which is provided on the tray 200. Thus, the warning light 240 can remind personnel that the automated guided vehicle 1000 is about to move into the area range, so that personnel can make avoidance in advance.

[0069] Furthermore, if Figure 1 As shown, the automatic guided vehicle 1000 uses wireless communication equipment. The automatic guided vehicle 1000 communicates and interacts with the equipment of the conveyor line or production line through the upper computer control system through the wireless network, thereby ensuring the stable transmission of signal communication without delays, interruptions, packet loss and other problems, and thus the automatic guided vehicle 1000 can be accurately controlled.
