[0001] The present application relates to the technical field of mobile robots, and in particular to an automatic guided transport vehicle. Background Art

[0002] With the improvement of living standards, the degree of automation in people's work and life is also constantly improving, and the efficiency of work and life has also been greatly improved. For example, an automated guided vehicle (AGV) is a transport vehicle that can perform automatic transportation. It can travel along a designated route through its own automatic guidance device to achieve automatic transportation of goods.

[0003] Generally, the automatic guided transport vehicle is generally equipped with a detachable battery to provide a power source. When charging is needed, it is only necessary to remove the battery on the automatic guided transport vehicle and replace it, which is simple and convenient to operate.

[0004] However, since the battery needs to be removed when the automated guided transport vehicle is being charged, the automated guided transport vehicle will be powered off, and the system will need to be restarted after the battery is installed. This process takes a long time, affecting the efficiency of the automated guided transport vehicle. Summary of the invention

[0005] An embodiment of the present application provides an automatic guided transport vehicle, which is used to solve the problem that the existing automatic guided transport vehicle needs to be powered off when replacing the battery, and it takes a long time to restart the system.

The third limiting portion is located between the first mounting portion and the second mounting portion and is connected to the second limiting portion. The elastic member is a spring, which is sleeved on the first limiting portion, one end of which is connected to the first mounting portion, and the other end of which is against the third limiting portion.

[0013] In some embodiments, there are multiple elastic components.

[0014] In some embodiments, the base assembly includes a chassis and a mounting shell. The interior of the chassis forms a mounting cavity and has an opening.

[0036] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0037] An Automated Guided Transport Vehicle is an unmanned vehicle that can automatically transport along a specified route, and can provide safety protection and various transport functions. Among them, the Automated Guided Transport Vehicle can include an electromagnetic or optical automatic guidance device, and then can be guided along the specified route by means of lasers and electromagnetic tracks. AVG transport vehicles can be used as mobile robots.

[0038] Generally, an automated guided vehicle can use a battery as its power source, and can use a computer to plan its route and behavior. When the battery of the automated guided vehicle is exhausted, the battery can be removed from the automated guided vehicle for replacement, and then the replaced battery can be installed in the automated guided vehicle. The operation is simple and convenient, and easy to implement.

[0039] However, as mentioned above, the battery of the automatic guided transport vehicle needs to be removed when it is replaced. At this time, the automatic guided transport vehicle will lose its power source, causing its system to be in a shutdown state. After the fully charged battery is installed, the system of the automatic guided transport vehicle needs to be restarted, which takes a long time and affects the efficiency of the use of the automatic guided transport vehicle.

[0040] Based on this, an embodiment of the present application provides an automatic guided transport vehicle, which can realize the function of automatic handling. Users can operate the automatic guided transport vehicle through terminals such as computers, so that the automatic guided transport vehicle can operate according to the specified route and realize automatic transportation of goods.

[0041] It is understandable that in order to realize the automatic transport function of the automatic guided transport vehicle, the automatic guided transport vehicle may include a guiding device. The guiding device can perform route planning and guidance so that the automatic guided transport vehicle can move along a specified route.

[0042] The specific type of the guiding device can be selected according to the actual situation, as long as it can achieve the route guidance and planning of the automatic guided transport vehicle. Exemplarily, the guiding device can be an optical guiding device.

[0043] like Figure 1 As shown, Figure 1 This is one of the partial structural diagrams of an automatic guided transport vehicle 100 provided in an embodiment of the present application, and the automatic guided transport vehicle 100 may include a base assembly 10, a first battery 20, and a second battery 30. Among them, the first battery 20 may be arranged on the base assembly 10 and detachably connected to the base assembly 10.

[0044] Therefore, when the power of the first battery 20 is exhausted, the first battery 20 can be removed from the base assembly 10 for replacement, and another fully charged first battery 20 can be installed on the base assembly 10 to provide a power source for the automatic guided transport vehicle 100.

[0045] It is understandable that the automatic guided transport vehicle 100 may include electrical components that require power supply, and the first battery 20 may be electrically connected to the electrical components to provide a power source for the electrical components. For example, in order to enable the automatic guided transport vehicle 100 to operate, the electrical components may include a drive device. The drive device may drive the automatic guided transport vehicle 100 to operate. Of course, the electrical components may also include other components, which are only described as examples.

[0046] The second battery 30 is disposed on the base assembly 10 and is used to be electrically connected to the first battery 20. In this way, after the user takes out the first battery 20, since the second battery 30 is disposed on the base assembly 10, the second battery 30 can be used as a backup battery to power the electrical components of the automatic guided transport vehicle 100. The system of the automatic guided transport vehicle 100 will not be shut down during the replacement of the first battery 20, and there is no need to restart the system, which saves time in starting the system and is more convenient to use. When the fully charged first battery 20 is reinstalled on the base assembly 10, the first battery 20 can be electrically connected to the second battery 30, and the second battery 30 can be charged to ensure that the second battery 30 has sufficient power when in standby mode.

[0047] The second battery 30 can be connected to the base assembly 10 in different ways. In some embodiments, the second battery 30 can be fixedly connected to the base assembly 10 by fasteners. As can be seen from the above, since the second battery 30 can be charged by the first battery 20, it is not necessary to disassemble it. In this way, the connection is made more firm and reliable by fasteners.

[0048] Of course, in other embodiments, the second battery 30 may also be snap-connected with the base assembly 10. In this way, when the second battery 30 needs to be disassembled, the second battery 30 may also be conveniently disassembled.

[0049] In order to place the first battery 20, as Figure 1 As shown, the base assembly 10 can form an installation cavity 101 with an opening, and the first battery 20 can be located in the installation cavity 101. In this way, the interior of the base assembly 10 provides an installation space for the first battery 20 and can also provide a certain degree of protection for the first battery 20. Figure 1 As shown, the second battery 30 may also be disposed in the mounting cavity 101 .

[0050] In order to ensure that the first battery 20 can be securely mounted on the base assembly 10, in some embodiments, as shown in FIG. Figure 1 As shown, the automated guided transport vehicle 100 may further include a position limiting assembly 40. The position limiting assembly 40 may be disposed on a side of the first battery 20 close to the opening.

[0051] The limiting assembly 40 can be used to connect with the base assembly 10 so that the first battery 20 can be installed on the base assembly 10. The limiting assembly 40 can also be used to separate from the base assembly 10 so that the first battery 20 can be separated from the base assembly 10.

[0052] Thus, through the stopper assembly 40, when the first battery 20 is installed on the base assembly 10, the connection between the stopper assembly 40 and the base assembly 10 can enable the first battery 20 to be stably installed on the base assembly 10. When the first battery 20 needs to be disassembled, the stopper assembly 40 can be separated from the base assembly 10, and the first battery 20 can be disassembled. At the same time, since the stopper assembly 40 is located on the side of the first battery 20 close to the opening, the user can easily operate the stopper assembly 40, and the operation is more convenient.

[0053] The stopper assembly 40 can be connected to the base assembly 10 in different ways. In some embodiments, the stopper assembly 40 can be snap-fitted with the base assembly 10. In this way, when the stopper assembly 40 is snap-fitted with the base assembly 10, the first battery 20 can be stably mounted on the base assembly 10.

[0054] Of course, the limit assembly 40 can also be connected to the base assembly 10 in other ways. Exemplarily, in other embodiments, the limit assembly 40 can also be connected to the base assembly 10 by magnetic attraction. In this case, the limit assembly 40 and the base assembly 10 can both include magnetic suction parts. In this way, through the mutual adsorption between the two magnetic suction parts, the limit assembly 40 and the base assembly 10 can also be kept in a relatively fixed state, so that the first battery 20 can be stably installed on the base assembly 10.

[0055] The first battery 20 can also be installed on the base assembly 10 in other ways. For example, the base assembly 10 can be designed with a snap-on structure, and the first battery 20 can be directly snap-on to the snap-on structure and installed on the base assembly 10. It can be understood that the first battery 20 can be fixed on the base assembly 10, and the specific form can be selected according to actual conditions, which is only described as an example here.

[0056] The base assembly 10 can have different compositions, such as Figure 1 As shown, in some embodiments, the base assembly 10 may include a chassis 11. The interior of the chassis 11 forms a mounting cavity 101 and has an opening. The chassis 11 may serve as the bottom structure of the automatic guided transport vehicle 100. For example, Figure 2 As shown, Figure 2 for Figure 1 The front view of the automated guided transporter 100 is shown. The automated guided transporter 100 may include wheels 111 , and the wheels 111 may be installed at the bottom of the chassis 11 .

[0057] At the same time, if Figure 3 As shown, Figure 3 This is a second partial structural diagram of an automatic guided transport vehicle 100 provided in an embodiment of the present application, the base assembly 10 ( Figure 1) may also include a mounting shell 12. The mounting shell 12 may be disposed in the mounting cavity 101 ( Figure 2 ) and chassis 11( Figure 1 ) connection. Thus, the mounting shell 12 can be fixed inside the chassis 11.

[0058] Among them, Figure 3 As shown, the mounting shell 12 may include a bottom wall 121 and a side wall 122. The side wall 122 may be located on one side of the bottom wall 121, and may be surrounded by a slide groove with the bottom wall 121, and a slide groove opening may be formed on one side of the side wall 122 close to the opening. The first battery 20 may be slidably connected in the slide groove of the mounting shell 12. In this way, the slide groove may provide a placement position for the first battery 20. At the same time, since the first battery 20 is slidably connected in the slide groove, the first battery 20 may be conveniently slid in and out of the slide groove opening of the slide groove, and installation and removal are more convenient and quick.

[0059] At the same time, based on the above scheme, Figure 1 As shown, the second battery 30 can be installed on the chassis 11. Exemplarily, the second battery 30 can be located below the first battery 20. In this way, the first battery 20 and the second battery 30 can be arranged in the height direction, so that the size of the chassis 11 can be reduced.

[0060] In addition, if Figure 3 As shown, a handle 21 may be provided on one side of the first battery 20 near the slot opening. In this way, the user can take out the first battery 20 by holding the handle 21, making it more convenient to take out the first battery 20.

[0061] Of course, in some other embodiments, the base assembly 10 may also only include the chassis 11 . In this case, both the first battery 20 and the second battery 30 may be directly disposed on the chassis 11 .

[0062] like Figure 3 and Figure 4 As shown, Figure 4 The third schematic diagram of a partial structure of an automatic guided transport vehicle 100 provided in an embodiment of the present application, in order to form a slide groove, the side wall 122 may include two first side walls 1221 arranged opposite to each other. The interval between the two first side walls 1221 close to the opening can form the above-mentioned slide groove. At the same time, in order to enable the first battery 20 to slide in and out better, in some embodiments, the chassis 11 assembly may also include a plurality of rollers 13.

[0063] A plurality of rollers 13 are distributed on the two first side walls 1221. At least part of the rollers 13 is arranged opposite to the chassis 11, and the rotation axis of the rollers 13 is perpendicular to the bottom wall 121. In this way, when the first battery 20 is arranged in the slide groove, the first battery 20 can be in contact with the rollers 13. Since the rotation axis of the rollers 13 is perpendicular to the bottom wall 121, when the first battery 20 slides along the extension direction of the slide groove, the rollers 13 can rotate with it, play a certain guiding role, and facilitate the sliding of the first battery 20.

[0064] For example, in order to enable the roller 13 to rotate, the roller 13 can be mounted on the first side wall 1221 via a rotating shaft. The roller 13 is rotatably connected to the rotating shaft. In this way, the roller 13 can be rotated via the rotating shaft. The number of rollers 13 can also be set according to actual needs, and no further limitation is made here.

[0065] Continue to refer to Figure 3 In some embodiments, the base assembly 10 may further include a plurality of mounting seats 14 and a plurality of balls 15. The plurality of mounting seats 14 are disposed on the bottom wall 121, and are located on a side of the bottom wall 121 close to the side wall 122. A mounting groove (not shown) is formed on the mounting seat 14. The plurality of balls 15 may be disposed in the mounting grooves, respectively, and movably connected to the mounting grooves. In this way, the balls 15 may roll in the mounting grooves.

[0066] Therefore, when the first battery 20 is placed in the chute, it can be placed on the ball 15, and when the first battery 20 moves, the ball 15 can roll. In this way, the force applied to the first battery 20 during the movement is rolling friction, which is small, so that the first battery 20 can easily slide in the chute.

[0067] Of course, in other embodiments, the roller 13 may not be provided on the first side wall 1221, and the first battery 20 may slide in the slide groove only by external force. Figure 4 As shown, in some embodiments, the bottom wall 121 may not be provided with the mounting seat 14 ( Figure 3 ) and ball 15( Figure 3 ). In this way, the first slide groove can slide by overcoming the sliding friction force.

[0068] Continue to refer to Figure 4 The side wall 122 may further include a second side wall 1222. The second side wall 1222 may be located at the first battery 20 ( Figure 3 ) is away from the side of the opening. In this way, the second side wall 1222 can play a blocking role to prevent the first battery 20 from sliding too long and directly falling out of the slide slot.

[0069] Furthermore, in some embodiments, such as Figure 4As shown, a blocking portion 1223 may be formed on the second side wall 1222. Figure 3 ) can be located on the side of the blocking portion 1223 away from the bottom wall 121. In this way, when the first battery 20 is set on the slide slot, since a part of the first battery 20 is located on the side of the blocking portion 1223 close to the bottom wall 121, the blocking portion 1223 can play a blocking role, so that the first battery 20 cannot move in the direction away from the bottom wall 121, ensuring that the first battery 20 can be stably placed on the slide slot.

[0070] Among them, the shape of the blocking portion 1223 can be designed according to actual conditions. Exemplarily, the blocking portion 1223 can be L-shaped. In addition, in order to protect the first battery 20, in some embodiments, the automatic guided transport vehicle 100 may also include a rubber pad (not shown in the figure). The rubber pad can be arranged on the side of the blocking portion 1223 close to the first battery 20. In this way, the first battery 20 can be abutted against by the rubber pad to prevent the blocking portion 1223 from directly abutting against the first battery 20 and causing damage to the first battery 20.

[0071] In addition, it can be seen from the above that the first battery 20 needs to provide a power source for the electrical components, such as Figure 4 As shown, the automated guided transport vehicle 100 may further include a plug-in connector 50. The plug-in connector 50 may be disposed on the second side wall 1222.

[0072] The connector 50 can be plugged into the first battery 20, and can also be connected to the electrical components and the second battery 30. In this way, the electric energy of the first battery 20 can be transmitted to the electrical components and the second battery 30 through the connector 50, providing a power source for them.

[0073] Depend on Figure 1 It can be seen that the chassis 11 can form a mounting cavity 101 with an opening. Therefore, in order to protect the first battery 20 and the second battery 30. Figure 5 As shown, Figure 5 The fourth partial structural diagram of an automatic guided transport vehicle 100 provided in an embodiment of the present application, the base assembly 10 may further include a baffle 16. The baffle 16 may be movably connected to the chassis 11.

[0074] The baffle 16 can cover the opening of the installation cavity 101, so that the first battery 20 and the second battery 30 are completely located inside and are not exposed. When the first battery 20 needs to be removed, the baffle 16 can open the opening of the installation cavity 101. At this time, the user can directly take the first battery 20 out of the installation slot.

[0075] The baffle 16 can be connected to the chassis 11 in different ways. For example, the baffle 16 can be detachably connected to the chassis 11. For example, the baffle 16 can be magnetically connected to the chassis 11. When the opening of the installation cavity 101 needs to be opened, the baffle 16 can be directly removed. When the opening of the installation cavity 101 needs to be blocked, the baffle 16 can be installed.

[0076] As can be seen from the above, the first battery 20 can be connected to the base assembly 10 through the limiting assembly 40. The structure of the limiting assembly 40 provided in the embodiment of the present application is further exemplified below. Figure 6 As shown, Figure 6 The schematic diagram of the structure of a limit assembly 40 provided in an embodiment of the present application is shown, and the limit assembly 40 may include a mounting plate 41 and an elastic assembly 42. The mounting plate 41 may be connected to the first battery 20. Since the connection with the first battery 20 is only through the mounting plate 41, it is not necessary to cover the entire first battery 20, thereby saving materials and reducing production costs.

[0077] The elastic component 42 can be connected to the mounting plate 41. At the same time, the inner wall of the mounting cavity 101 can form a limiting hole. Exemplarily, a limiting hole can be provided on the first side wall 1221 of the mounting shell 12. The elastic component 42 can be used to engage with the limiting hole under the action of elastic force. In this way, when installing, as long as the position of the elastic component 42 corresponds to the position of the limiting hole, the elastic component 42 can engage with the limiting hole under the action of elastic force, and the engagement is more convenient.

[0078] Of course, in other embodiments, the limit assembly 40 may also include a buckle structure. In this case, the user can manually operate the buckle structure to engage with the limit hole, and the limit assembly 40 can also be engaged with the base assembly 10. It is understandable that the limit assembly 40 can be engaged with the base assembly 10 through different structures, as long as the engagement between the limit assembly 40 and the base assembly 10 can be achieved, which is only described as an example.

[0079] In some embodiments, Figure 6 As shown, the elastic assembly 42 may include an elastic member 421 and a limiting member 422. The elastic member 421 may be connected to the mounting plate 41. The limiting member 422 may be connected to the elastic member 421, and is used to move under the elastic force of the elastic member 421 to extend into the limiting hole.

[0080] Thus, by providing the elastic member 421 and the limiting member 422, the limiting member 422 can be moved by utilizing the elastic force of the elastic member 421, so that the limiting member 422 can extend into the limiting hole and engage with the limiting hole. When it is necessary to separate the limiting assembly 40 from the limiting hole, the user can operate the limiting member 422 to separate the limiting member 422 from the limiting hole to complete the separation of the limiting assembly 40 from the limiting hole.

[0081] At the same time, the limiting member 422 can prevent the elastic member 421 from being directly engaged with the limiting hole, thereby reducing the loss of the elastic member 421 and increasing the service life of the elastic member 421.

[0082] Of course, in other embodiments, the elastic component 42 may also only include the elastic member 421. In this case, the elastic member 421 may directly extend into the limiting hole under the action of its elastic force and be engaged with the limiting hole.

[0083] The limiting member 422 and the elastic member 421 can be matched in different ways. In some embodiments, for example, Figure 6 As shown, the limiting member 422 may include a first limiting portion 4221, a second limiting portion 4222 and a third limiting portion 4223. The second limiting portion 4222 is slidably connected to the first limiting portion 4221, and the third limiting portion 4223 is connected to the second limiting portion 4222. Thus, the second limiting portion 4222 can move relative to the first limiting portion 4221. Exemplarily, the first limiting portion 4221 and the second limiting portion 4222 can form a telescopic rod.

[0084] At the same time, if Figure 6 As shown, in order to fix the elastic member 421 and the limiting member 422 , the mounting plate 41 may include a plate body 411 , a first mounting portion 412 and a second mounting portion 413 .

[0085] The first mounting portion 412 may be located at one side of the plate body 411 and connected to the plate body 411. A first mounting hole may be provided on the first mounting portion 412. The second mounting portion 413 may be located at one side of the plate body 411 close to the first mounting portion 412 and connected to the plate body 411. A second mounting hole may be provided on the second mounting plate 41.

[0086] like Figure 6 As shown, one end of the first limiting portion 4221 can be located in the first mounting hole and connected to the first mounting hole. The second limiting portion 4222 is slidably connected to the other end of the first limiting portion 4221 and is penetrated in the second mounting hole. Thus, the limiting member 422 can be installed on the mounting plate 41 through the first mounting hole of the first mounting portion 412. Exemplarily, the first limiting portion 4221 can be threadedly connected to the first mounting hole.

[0087] The second limiting portion 4222 is slidably connected to the other end of the first limiting portion 4221 and is inserted into the second mounting hole. The third limiting portion 4223 is located between the first mounting portion 412 and the second mounting portion 413. The elastic member 421 may be a spring, which is sleeved on the first limiting portion 4221, with one end connected to the first mounting portion 412 and the other end abutting against the third limiting portion 4223.

[0088] Therefore, the elastic force of the elastic member 421 can drive the third limiting portion 4223 to move, and the third limiting portion 4223 is connected to the second limiting portion 4222, thereby driving the second limiting portion 4222 to slide relative to the first limiting portion 4221 in the second mounting hole, and extend into the limiting hole to be snap-connected with the limiting hole.

[0089] At the same time, if Figure 6 As shown, since the third limiting portion 4223 is located between the first mounting portion 412 and the second mounting portion 413, after the third limiting portion 4223 moves a certain distance, the third limiting portion 4223 can abut against the second mounting portion 413, thereby limiting the further movement of the third limiting portion 4223.

[0090] Of course, in other embodiments, the limiting member 422 may also include only the first limiting portion 4221. In this case, one end of the elastic member 421 may be connected to the first mounting portion 412, and the other end of the elastic member 421 may be connected to the first limiting portion 4221, and the first limiting portion 4221 is inserted into the second mounting hole. In this way, the elastic member 421 can directly drive the first limiting member 422 to move, so that the first limiting portion 4221 extends into the limiting hole and engages with the limiting hole. In this case, the elastic member 421 may also be a spring.

[0091] It is understandable that the limiting member 422 and the elastic member 421 may have different structures, as long as the elastic member 421 can drive the limiting member 422 to move and engage with the limiting hole. This is only described as an example here.

[0092] In some embodiments, continue to refer to Figure 6 , the number of elastic components 42 can be multiple. In this way, the connection can be made more reliable by snapping multiple elastic components 42 with the limiting holes. Exemplarily, the number of elastic components 42 can be two. Correspondingly, Figure 4 The two first side walls 1221 shown may each be provided with a limiting hole. Of course, in other embodiments, the number of the elastic component 42 may also be one, which may be specifically designed according to actual conditions.

[0093] In addition, if Figure 7 As shown, Figure 71 is a schematic diagram of the structure when the first battery 20 is arranged on the mounting shell 12. A fixing plate 22 may also be arranged on the first battery 20. The mounting plate 41 may be mounted on the first battery 20 through the fixing plate 22. Exemplarily, the mounting plate 41 may be threadedly connected to the fixing plate 22 through a fastener.

[0094] Below, based on the automatic guided transport vehicle 100 provided in the embodiment of the present application, the steps of removing and replacing the first battery 20 are exemplarily described.

[0095] First, based on Figure 5 The structure shown in FIG. 1 can first remove the baffle 16 from the chassis 11, and then Figure 1 The structure of the first battery 20 is exposed. Figure 8 As shown, Figure 8 for Figure 3 , move the third limiting portion 4223 so that the second limiting portion 4222 can extend from the limiting hole. At this time, the user can pull the handle 21 to take the first battery 20 out of the mounting shell 12.

[0096] Then, if Fig. 9 As shown, Fig. 9 for Figure 3 The fully charged first battery 20 is pushed into the mounting shell 12, and the first battery 20 is plugged into the connector 50 to complete the installation. Figure 5 The baffle 16 shown can be reinstalled on the chassis 11.

[0097] In addition, if Fig. 9 As shown, in order to facilitate the insertion of the first battery 20, one end of the installation shell 12 with the sliding groove is a trumpet-shaped opening. In this way, during the insertion of the first battery 20, the second limiting portion 4222 moves slowly, causing the elastic member 421 to gradually produce elastic deformation, and when reaching the position where the limiting hole is located, the elastic deformation is restored, so that the second limiting portion 4222 can extend into the limiting hole under the action of elastic force and engage with the limiting hole.

[0098] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
