Description

Technical Field

[0001] This utility model relates to the field of AGV technology, specifically to a drive lifting mechanism and an AGV. Background Technology

[0002] With the continuous development of technology, AGV (Automated Guided Vehicle) handling robots are being used more and more widely in the field of modern logistics. Many industries, such as automobiles, new energy, electronics and transportation, have become the main application areas for AGVs.

[0003] In existing technologies, AGVs experience various malfunctions during operation. Among these, the drive module is a common point of failure. When the drive module malfunctions, the drive wheels may seize up, preventing them from rotating properly. Therefore, a drive lifting mechanism is needed to separate the drive wheels from the running surface, allowing the AGV to be moved to the repair location via other auxiliary wheels. Currently, common drive lifting mechanisms include electric and manual lifting. Electric lifting is convenient and efficient, but it occupies more space and is more expensive, making it unsuitable for mass production. Manual lifting is less expensive, but it is complex to operate, inconvenient to use, and reduces AGV maintenance efficiency. Utility Model Content

[0004] In view of this, the present invention provides a drive lifting mechanism to solve the problems that the existing manual drive lifting mechanism of AGV is complicated to operate, inconvenient to use, and reduces the maintenance efficiency of AGV.

[0005] In a first aspect, this utility model provides a drive lifting mechanism, comprising:

[0006] An installation structure is provided, which is suitable for being installed on the AGV body. The installation structure and the AGV body together form an installation cavity. A sliding part is provided on the installation structure and communicates with the installation cavity.

[0007] A driving structure includes a sliding member and a driving assembly. The sliding member is slidably disposed within the sliding portion, and the driving assembly is disposed on the sliding member and within the mounting cavity.

[0008] The lifting structure includes a rotating component, a cam assembly, and a bearing assembly. The bearing assembly is disposed on the mounting structure. One end of the rotating component is adapted to pass through the sliding component and connect to the bearing assembly. The cam assembly is sleeved on the rotating component, and the side wall surface of the cam assembly abuts against the sliding component.

[0009] The other end of the rotating member is adapted to receive an external force. Under the action of the external force, the rotating member is adapted to drive the cam assembly to rotate, so that the cam assembly drives the sliding member to rise or fall.

[0010] Beneficial effects: The drive structure and lifting structure are mounted onto the AGV body through the mounting structure, and the rotating component drives the cam assembly to rotate, so that the cam assembly drives the sliding component to move relative to the mounting structure. Since the mounting structure is stationary relative to the AGV body, when the sliding component moves relative to the mounting structure, the sliding component also moves relative to the AGV body. This allows the drive assembly to move relative to the AGV body when the sliding component drives the drive assembly to move. In this way, the drive assembly can be separated from and contacted with the walking surface, which helps to reduce the operation difficulty of the drive lifting mechanism and improves the maintenance efficiency of the AGV.

[0011] In one alternative embodiment, the cam assembly includes a cam and a rolling element, the cam being sleeved on the rotating element, the rolling element being rotatably disposed at the end of the cam, and the sidewall surface of the rolling element being adapted to abut against the sliding element.

[0012] Beneficial effects: By setting the cam assembly including a cam and a rolling element, the rolling element in this embodiment is a roller. The cam is sleeved on the rotating element, and the rolling element is rotatably disposed at the end of the cam. The side wall of the rolling element can abut against the sliding element. Thus, when the rotating element rotates, the cam will rotate synchronously with the rotating element, and the end of the cam will move relative to the sliding element, so that the rolling element rolls relative to the sliding element. This allows the rolling element to drive the sliding element to move relative to the mounting structure, so that the sliding element drives the driving structure to move synchronously relative to the mounting structure. Specifically, by abutting against the sliding element, the contact between the rolling element and the sliding element becomes a rolling contact, thereby reducing the frictional resistance between the rolling element and the sliding element.

[0013] In one alternative embodiment, the bearing assembly includes a bearing housing and a bearing, the bearing housing being disposed on the mounting structure, the bearing being rotatably disposed on the bearing housing, and the bearing being connected to one end of the rotating member.

[0014] Beneficial effects: By setting the bearing assembly to include a bearing housing and a bearing, wherein the bearing housing is set on the mounting structure and the bearing is rotatably mounted on the bearing housing, and the rotating part is connected to the bearing through one end of the sliding part, the rotating part can rotate on the bearing housing through the bearing when the other end of the rotating part receives external force, thereby reducing the rotational resistance of the rotating part.

[0015] In an optional embodiment, a guide structure is further included, the guide structure comprising a plurality of guide components, each of the guide components comprising an adapter and a guide member, the adapter being connected to the sliding member, one end of the guide member being adapted to penetrate the mounting structure and connect to the adapter, and the guide member being slidably connected to the sliding member.

[0016] Beneficial effects: By setting a guide structure between the mounting structure and the sliding member, the guide structure specifically includes several guide components, each guide component including a transition piece and a guide piece. In this embodiment, the transition piece and the guide piece are a transition plate and a guide rod, respectively. The transition piece is connected to the sliding member, and one end of the guide piece can penetrate the mounting structure and connect to the transition piece. The guide piece and the sliding member are slidably connected, so that when the sliding member moves relative to the mounting structure, the transition piece will move synchronously with the sliding member, thereby enabling the guide piece to provide guidance for the transition piece and the sliding member.

[0017] In one alternative embodiment, the guide assembly further includes a limiting member disposed at the end of the guide member away from the adapter, the limiting member being adapted to abut against the mounting structure to limit the guide member.

[0018] Beneficial effects: By setting the guide component, a limiting member is also included. In this embodiment, the limiting member is a limiting nut. The limiting member is specifically set at the end of the guide component away from the adapter. So when the end of the guide component away from the adapter approaches the mounting structure, the limiting member can abut against the mounting structure to limit the guide component and prevent the end of the guide component away from the adapter from detaching from the mounting structure.

[0019] In one alternative embodiment, a portion of the guide assembly further includes a biasing member sleeved on the guide member, with both ends of the biasing member abutting against the mounting structure and the adapter, respectively. The biasing member is configured to have an elastic force that drives the adapter away from the mounting structure under external force.

[0020] Beneficial effects: By setting a partial guide component including a biasing element, which in this embodiment is a spring, the biasing element is specifically sleeved on the guide component, and both ends of the biasing element abut against the mounting structure and the adapter respectively. At the same time, the biasing element is configured to have an elastic force that drives the adapter away from the mounting structure under the action of external force. In this way, when the drive component moves up and down under the action of external force, the sliding element and the adapter can transmit the external force to the biasing element, so that the biasing element can absorb the external force on the drive component through the sliding element and the adapter and convert the external force into an elastic force to ensure the stability of the drive component.

[0021] In one alternative embodiment, another portion of the guide assembly further includes a buffer sleeved on the guide and connected to the adapter, the buffer being configured to have an elastic force that deforms under external force.

[0022] Beneficial effects: By setting another part of the guide component, a buffer element is also included. In this embodiment, the buffer element is a buffer block, specifically a polyurethane block. The buffer element is specifically sleeved on the guide element and connected to the adapter. The buffer element is configured to have elastic force that deforms under external force. So when the adapter approaches the mounting structure, the buffer element can abut against the mounting structure and deform to generate elastic force, thereby buffering the collision force between the adapter and the mounting structure through the elastic force.

[0023] In one optional embodiment, the mounting structure includes a mounting member and at least two support members, the two support members being disposed at both ends of the mounting member and both connected to the mounting member, and any one of the support members being adapted to be connected to the AGV body;

[0024] The mounting component, the two supporting components, and the AGV body together form the mounting cavity, and the sliding part is formed on the mounting component.

[0025] Beneficial effects: By setting the installation structure including an installation component and two support components, the installation component and the support block are respectively an installation plate and a support block in this embodiment. The two support components are respectively set at both ends of the installation component, and each support component is connected to the installation component. At the same time, each support component can be connected to the AGV body. In this way, the installation component can be installed on the AGV body through the two support components, and an installation cavity can be formed between the two support components, the installation component and the AGV body. In addition, a sliding part is opened on the installation component, and the sliding component is slidably connected to the installation component through the sliding part.

[0026] In one optional embodiment, the drive assembly includes a drive wheel and a drive unit, the drive wheel and the drive unit being respectively disposed on both sides of the sliding member, and the drive end of the drive unit being adapted to pass through the sliding member and connect with the drive wheel;

[0027] The drive unit includes a drive component and a reducer component. The drive end of the drive component is connected to the reducer component, and the drive end of the reducer component is adapted to pass through the sliding component and connect to the drive wheel.

[0028] Beneficial effects: By setting the drive assembly to include a drive wheel and a drive unit, wherein the drive wheel and drive unit are respectively located on both sides of the sliding member, and the drive end of the drive unit can pass through the sliding member and connect to the drive wheel, the sliding member can drive the drive assembly to move synchronously, and the drive end of the drive unit can drive the drive wheel to rotate, thereby realizing the operation of the AGV; specifically, the drive unit includes a drive component and a reducer component, which in this embodiment are a drive motor and a reducer, respectively, wherein the drive end of the drive component is connected to the reducer component, and the drive end of the reducer component can pass through the sliding member and connect to the drive wheel, thereby realizing the rotation of the drive wheel.

[0029] Secondly, this utility model also provides an AGV, including an AGV body and the aforementioned drive and lifting mechanism.

[0030] Beneficial effects: By installing the drive lifting mechanism on the AGV body, that is, by installing the drive structure and lifting structure onto the AGV body through the installation structure of the drive lifting mechanism, and by driving the cam assembly to rotate through the rotating component, the cam assembly drives the sliding component to move relative to the installation structure. Since the installation structure is stationary relative to the AGV body, when the sliding component moves relative to the installation structure, the sliding component also moves relative to the AGV body. Thus, when the sliding component drives the drive assembly to move, the drive assembly can move relative to the AGV body. In this way, the separation and contact between the drive assembly and the walking surface can be achieved, which helps to reduce the operation difficulty of the drive lifting mechanism and improves the maintenance efficiency of the AGV.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The following is combined Figure 1 and Figure 2 The following describes embodiments of the present invention.

[0038] According to embodiments of the present invention, in one aspect, a drive lifting mechanism is provided, such as... Figure 1 and Figure 2 As shown, the system includes an installation structure 1, a drive structure 2, and a lifting structure. The installation structure 1 is adapted to be mounted on the AGV body, and the installation structure 1 and the AGV body together form an installation cavity. The installation structure 1 has a sliding part that communicates with the installation cavity. The drive structure 2 includes a sliding member 21 and a drive assembly 22. The sliding member 21 is slidably disposed in the sliding part, and the drive assembly 22 is disposed on the sliding member 21 and disposed in the installation cavity. The lifting structure includes a rotating member 31, a cam assembly 32, and a bearing assembly 33. The bearing assembly 33 is disposed on the installation structure 1. One end of the rotating member 31 is adapted to pass through the sliding member 21 and connect with the bearing assembly 33. The cam assembly 32 is sleeved on the rotating member 31, and the side wall of the cam assembly 32 abuts against the sliding member 21. The other end of the rotating member 31 is adapted to receive external force. Under the action of external force, the rotating member 31 is adapted to drive the cam assembly 32 to rotate, so that the cam assembly 32 drives the sliding member 21 to rise or fall.

[0039] The aforementioned drive and lifting mechanism comprises a drive structure 2 and a lifting structure mounted on the mounting structure 1. The mounting structure 1 can be mounted on the AGV body, and when mounted on the AGV body, the mounting structure 1 and the AGV body together form a mounting cavity. The mounting structure 1 also has a sliding portion communicating with the mounting cavity. In this embodiment, the sliding portion is a sliding hole. The drive structure 2 specifically includes a sliding member 21 and a drive assembly 22. The sliding member 21 is slidably disposed within the sliding portion, and the drive assembly 22 is disposed on the sliding member 21 and specifically within the mounting cavity. Thus, under external force, the sliding member 21 can slide relative to the mounting structure 1 through the sliding portion, and drive the drive assembly 22 to move synchronously, thereby realizing the movement of the drive structure 2.

[0040] In addition, the lifting structure specifically includes a rotating component 31, a cam assembly 32, and a bearing assembly 33. In this embodiment, the rotating component 31 is a rotating shaft. The bearing assembly 33 is mounted on the mounting structure 1. One end of the rotating component 31 can pass through the sliding component 21 and connect to the bearing assembly 33, while the other end of the rotating component 31 can receive external force. Under the action of external force, the rotating component 31 can rotate relative to the bearing assembly 33. The cam assembly 32 is specifically sleeved on the rotating component 31, and the side wall of the cam assembly 32 abuts against the sliding component 21. Thus, when the rotating component 31 rotates relative to the bearing assembly 33, the rotating component 31 can drive the cam assembly 32 to rotate synchronously, thereby enabling the cam assembly 32 to drive the sliding component 21 to rise or fall relative to the mounting structure 1. The sliding component 21 can drive the drive assembly 22 to rise or fall synchronously. In this way, when the drive assembly 22 fails, it can be raised and separated from the traveling surface. When the drive assembly 22 is repaired, it can be lowered and brought into contact with the traveling surface to achieve normal operation.

[0041] In summary, the drive structure 2 and the lifting structure are installed onto the AGV body via the mounting structure 1. The rotating component 31 drives the cam assembly 32 to rotate, which in turn drives the sliding component 21 to move relative to the mounting structure 1. Since the mounting structure 1 is stationary relative to the AGV body, when the sliding component 21 moves relative to the mounting structure 1, it also moves relative to the AGV body. This allows the drive assembly 22 to move relative to the AGV body when the sliding component 21 drives it. In this way, the drive assembly 22 can be separated from and contacted with the walking surface, which helps reduce the operational difficulty of the drive lifting mechanism and improves the maintenance efficiency of the AGV.

[0042] In one embodiment, such as Figure 2 As shown, the cam assembly 32 includes a cam 321 and a rolling element 322. The cam 321 is sleeved on the rotating element 31, and the rolling element 322 is rotatably disposed at the end of the cam 321. The side wall surface of the rolling element 322 is adapted to abut against the sliding element 21.

[0043] The aforementioned drive lifting mechanism, by setting a cam assembly 32 including a cam 321 and a rolling element 322, wherein the rolling element 322 is a roller in this embodiment, wherein the cam 321 is sleeved on the rotating member 31, and the rolling element 322 is rotatably disposed at the end of the cam 321, and the side wall surface of the rolling element 322 can abut against the sliding member 21, so that when the rotating member 31 rotates, the cam 321 will rotate synchronously with the rotating member 31, and the end of the cam 321 will move relative to the sliding member 21, so that the rolling element 322 rolls relative to the sliding member 21, thereby enabling the rolling element 322 to drive the sliding member 21 to move relative to the mounting structure 1, so that the sliding member 21 drives the drive structure 2 to move synchronously relative to the mounting structure 1. Specifically, by the rolling element 322 abutting against the sliding member 21, the contact between the rolling element 322 and the sliding member 21 becomes a rolling contact, thereby reducing the frictional resistance between the rolling element 322 and the sliding member 21.

[0044] In one embodiment, such as Figure 1 As shown, the bearing assembly 33 includes a bearing housing 331 and a bearing 332. The bearing housing 331 is mounted on the mounting structure 1, and the bearing 332 is rotatably mounted on the bearing housing 331. The bearing 332 is connected to one end of the rotating member 31.

[0045] The aforementioned drive lifting mechanism includes a bearing assembly 33 comprising a bearing housing 331 and a bearing 332. The bearing housing 331 is mounted on the mounting structure 1, and the bearing 332 is rotatably mounted on the bearing housing 331. The rotating member 31 is connected to the bearing 332 at one end through the sliding member 21. Thus, when the other end of the rotating member 31 receives an external force, the rotating member 31 can rotate on the bearing housing 331 via the bearing 332, thereby reducing the rotational resistance of the rotating member 31.

[0046] In one embodiment, such as Figure 1 and Figure 2 As shown, it also includes a guide structure, which includes several guide components. Each guide component includes an adapter 411 and a guide 412. The adapter 411 is connected to the sliding member 21. One end of the guide 412 is adapted to pass through the mounting structure 1 and connect to the adapter 411. The guide 412 is slidably connected to the sliding member 21.

[0047] The aforementioned drive lifting mechanism utilizes a guide structure positioned between the mounting structure 1 and the sliding member 21. This guide structure comprises several guide components, each including a connector 411 and a guide member 412. In this embodiment, the connector 411 and the guide member 412 are a connector plate and a guide rod, respectively. The connector 411 is connected to the sliding member 21, and one end of the guide member 412 can penetrate the mounting structure 1 and connect to the connector 411. The guide member 412 and the sliding member 21 are slidably connected. Thus, when the sliding member 21 moves relative to the mounting structure 1, the connector 411 moves synchronously with the sliding member 21, thereby enabling the guide member 412 to provide guidance for both the connector 411 and the sliding member 21.

[0048] In one embodiment, such as Figure 1 As shown, the guide assembly also includes a limiting member 413, which is disposed at the end of the guide member 412 away from the adapter 411. The limiting member 413 is adapted to abut against the mounting structure 1 to limit the guide member 412.

[0049] The aforementioned drive lifting mechanism, by setting the guide component, also includes a limiting member 413. In this embodiment, the limiting member 413 is a limiting nut. The limiting member 413 is specifically set at the end of the guide member 412 away from the adapter 411. Thus, when the end of the guide member 412 away from the adapter 411 approaches the mounting structure 1, the limiting member 413 can abut against the mounting structure 1 to limit the guide member 412 and prevent the end of the guide member 412 away from the adapter 411 from detaching from the mounting structure 1.

[0050] In one embodiment, such as Figure 1 As shown, some guide components also include a biasing member 414, which is sleeved on the guide member 412, and the two ends of the biasing member 414 abut against the mounting structure 1 and the adapter 411 respectively. The biasing member 414 is configured to have an elastic force that drives the adapter 411 away from the mounting structure 1 under the action of external force.

[0051] The aforementioned drive lifting mechanism includes a biasing member 414 as part of the guide components. In this embodiment, the biasing member 414 is a spring. Specifically, the biasing member 414 is sleeved on the guide member 412, and its two ends abut against the mounting structure 1 and the adapter 411, respectively. At the same time, the biasing member 414 is configured to have an elastic force that drives the adapter 411 away from the mounting structure 1 under the action of external force. Thus, when the drive assembly 22 moves up and down under the action of external force, the sliding member 21 and the adapter 411 can transmit the external force to the biasing member 414, so that the biasing member 414 can absorb the external force on the drive assembly 22 through the sliding member 21 and the adapter 411 and convert the external force into an elastic force to ensure the stability of the drive assembly 22.

[0052] In one embodiment, such as Figure 2 As shown, another part of the guide assembly also includes a buffer 415, which is sleeved on the guide 412 and connected to the adapter 411. The buffer 415 is configured to have an elastic force that deforms under external force.

[0053] The aforementioned drive lifting mechanism, by setting another part of the guide component, also includes a buffer 415. In this embodiment, the buffer 415 is a buffer block, specifically a polyurethane block. The buffer 415 is specifically sleeved on the guide 412 and connected to the adapter 411. The buffer 415 is configured to have elastic force that deforms under external force, so that when the adapter 411 approaches the mounting structure 1, the buffer 415 can abut against the mounting structure 1 and deform to generate elastic force, so as to buffer the collision force between the adapter 411 and the mounting structure 1 through the elastic force.

[0054] In one embodiment, such as Figure 1 and Figure 2 As shown, the mounting structure 1 includes a mounting member 11 and at least two support members 12. The two support members 12 are disposed at both ends of the mounting member 11 and are connected to the mounting member 11. Any support member 12 is adapted to be connected to the AGV body. The mounting member 11, the two support members 12 and the AGV body together form a mounting cavity, and the sliding part is formed on the mounting member 11.

[0055] The aforementioned drive lifting mechanism includes an installation structure 1 comprising an installation member 11 and two support members 12. In this embodiment, the installation member 11 is a mounting plate and a support block, respectively. The two support members 12 are respectively located at both ends of the installation member 11, and each support member 12 is connected to the installation member 11. At the same time, each support member 12 can be connected to the AGV body. Thus, the installation member 11 can be installed on the AGV body through the two support members 12, and an installation cavity can be formed between the two support members 12, the installation member 11, and the AGV body. In addition, a sliding part is provided on the installation member 11, and the sliding member 21 is slidably connected to the installation member 11 through the sliding part.

[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, the drive assembly 22 includes a drive wheel 221 and a drive unit 222. The drive wheel 221 and the drive unit 222 are respectively disposed on both sides of the sliding member 21, and the drive end of the drive unit 222 is adapted to pass through the sliding member 21 and connect with the drive wheel 221. The drive unit 222 includes a drive member 2221 and a reducer 2222. The drive end of the drive member 2221 is connected with the reducer 2222, and the drive end of the reducer 2222 is adapted to pass through the sliding member 21 and connect with the drive wheel 221.

[0057] The aforementioned drive lifting mechanism includes a drive assembly 22 comprising a drive wheel 221 and a drive unit 222. The drive wheel 221 and the drive unit 222 are respectively disposed on both sides of the sliding member 21, and the drive end of the drive unit 222 can pass through the sliding member 21 and connect to the drive wheel 221. In this way, the sliding member 21 can drive the drive assembly 22 to move synchronously, and the drive end of the drive unit 222 can drive the drive wheel 221 to rotate, thereby realizing the operation of the AGV.

[0058] Specifically, the drive unit 222 includes a drive component 2221 and a reducer 2222. In this embodiment, the drive component 2221 and the reducer 2222 are a drive motor and a reducer, respectively. The drive end of the drive component 2221 is connected to the reducer 2222, and the drive end of the reducer 2222 can be connected to the drive wheel 221 through the sliding member 21. In this way, the rotation of the drive wheel 221 can be realized.

[0059] According to an embodiment of the present invention, another aspect also provides an AGV, such as... Figure 1 and Figure 2 As shown, the AGV includes the AGV body and the aforementioned drive and lifting mechanism. In this AGV structure, the drive and lifting mechanism is mounted on the AGV body; specifically, the drive structure 2 and the lifting structure are mounted to the AGV body via the mounting structure 1. A rotating component 31 drives the cam assembly 32 to rotate, causing the cam assembly 32 to drive the sliding component 21 to move relative to the mounting structure 1. Since the mounting structure 1 is stationary relative to the AGV body, when the sliding component 21 moves relative to the mounting structure 1, it also moves relative to the AGV body. This allows the drive assembly 22 to move relative to the AGV body when the sliding component 21 drives it, thus enabling the drive assembly 22 to move relative to the AGV body. This achieves separation and contact between the drive assembly 22 and the walking surface, reducing the operational difficulty of the drive and lifting mechanism and improving the maintenance efficiency of the AGV.
