DETAILED DESCRIPTION

[0042] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0044] The utility model discloses an industrial equipment, which may be an industrial container, or a production and processing equipment, or an industrial design product, or a transportation equipment, etc. The industrial equipment provided by the utility model also includes a protective cover driving device 100, which can be arranged on the outside of the industrial equipment to protect the internal components of the industrial equipment.

[0045] Specifically, see Figures 1 to 4The utility model provides a protective cover driving device 100, which includes a shell 10. The shape of the shell 10 can be roughly plate-shaped or have other structures. The shell 10 is provided with a first opening 11 and a second opening 12. It should be noted that the first opening 11 can be a single opening or a group of openings including multiple openings. The second opening 12 can also be a single opening or a group of openings including multiple openings. Specifically, it can be designed according to the components that need to be exposed inside the industrial equipment. According to the specific use requirements of the industrial equipment, the first opening 11 and the second opening 12 are designed so that when one group of openings is opened, the other group of openings should be closed, that is, it is necessary to avoid the situation where the two groups of openings are opened at the same time.

[0046] The shapes and sizes of the first opening 11 and the second opening 12 can be various, and are mainly designed according to the shapes and sizes of the corresponding internal components inside. It can be understood that according to relevant design requirements, the first opening 11 and the second opening 12 should not be opened at the same time, that is, when the first opening 11 is opened, the second opening 12 should remain closed, and when the second opening 12 is opened, the first opening 11 should remain closed.

[0047] For further information, see Figures 1 to 4 The housing 10 has an inner side and an outer side which are arranged opposite to each other. Figure 1 The main part shown is the inner side of the housing 10. Figures 2 to 4 The main part shown is the inner side of the housing 10. It should be noted that the specific orientation of the outer side and the inner side is relative to the internal components that need to be protected in the industrial equipment, that is, the inner side is the side facing the internal components, and the outer side is the side facing away from the internal components.

[0048] The protective cover driving device 100 provided in this embodiment further includes a second cover body 22, see Figures 2 to 4 The first cover 21 and the second cover 22 are respectively movably mounted on the housing 10. The first cover 21 has a closed state covering the first opening 11 and an open state opening the first opening 11. The second cover 22 has a closed state covering the second opening 12 and an open state opening the second opening 12. There are many ways for the first cover 21 and the second cover 22 to move with the housing 10, for example, they can be rotatably opened and closed relative to the first opening 11 and the second opening 12, or they can be slidably opened and closed, or they can be opened and closed in a manner that can be pushed and slidably, etc. It can be understood that the connection structure between the first cover 21 or the second cover 22 and the housing 10 can be adaptively designed according to its activity mode, for example, they can be connected to the housing 10 through a hinge structure, or they can be connected to the housing 10 through a sliding structure.

[0049] Please continue reading Figure 1 and Figures 8 to 11 The protective cover driving device 100 provided in this embodiment also includes a driving mechanism 30, which is used to drive the opening and closing actions of the first cover body 21 and the second cover body 22, and includes a driving member 40, a first linkage member 50 connected to the first cover body 21, and a second linkage member 60 connected to the second cover body 22. The driving member 40 is used to transmit power to drive the first cover body 21 and / or the second cover body 22 to move, and its power source can be manual or electric. When the power source of the driving member 40 is manual, it can be connected to a manual operating component (such as an emergency pull rope). Specifically, when the user manually operates the manual operating component, the driving member 40 will be driven to move forward or reverse along a preset path. When its power source is electric, such as Figure 1 and Figure 3 As shown, the driving member 40 can be transmission-connected to the motor 31, so that when the motor 31 rotates, the driving member 40 is driven to move forward or reversely along a preset path. The power source of the driving member 40 includes at least one of manual and electric, and in a preferred embodiment, the power source of the driving member 40 can include both manual and electric modes. The user can select a suitable power source to operate according to actual needs to realize the opening and closing of the first cover body 21 and / or the second cover body 22.

[0050] The driving member 40 is connected to the first linkage member 50 and the second linkage member 60 in a transmission manner, so that when the driving member 40 is driven to move along a preset path, the first linkage member 50 and / or the second linkage member 60 are linked therewith, and drive the first cover body 21 and the second cover body 22 to which they are connected to move accordingly, and switch between an open state and a closed state. It should be noted that the specific structure of the driving member 40, the first linkage member 50 and the second linkage member 60 can be various, and can be adaptively designed according to the connection structure between the first cover body 21 and the second cover body 22 and the housing 10, for example, it can be a mutually matched multi-stage gear transmission structure, a multi-link driving mechanism 30, or other composite transmission mechanisms.

[0051] In the present invention, the preset path refers to the directional moving path of the driving member 40, which changes according to the specific structure of the driving member 40 and the transmission connection mode between the driving member 40 and the first linkage member 50 and the second linkage member 60. Specifically, the preset path can be extended along a straight line, a broken line, or a curve, etc. The forward movement of the driving member 40 along the preset path means that it moves along the preset direction according to its moving trajectory under the drive of a manual or electric power source, and the reverse movement of the driving member 40 along the preset path means that it moves in the direction opposite to the preset direction according to its moving trajectory under the drive of a manual or electric power source.

[0052] Further, in the stroke in which the driving member 40 is driven to move forward along the preset path, the first linkage member 50 is linked with the driving member 40 so that the first cover 21 switches from the closed state to the open state, while the second cover 22 remains closed, or the second linkage member 60 is linked with the driving member 40 so that the second cover 22 switches from the open state to the closed state. In the process in which the driving member 40 is driven to move in the reverse direction along the preset path, the first linkage member 50 is linked with the driving member 40 so that the first cover 21 switches from the open state to the closed state, or the second linkage member 60 is linked with the driving member 40 so that the second cover 22 switches from the closed state to the open state, while the first cover 21 remains closed. It can be understood that the linkage action of the first cover 21 and / or the second cover 22 with the driving member 40 can be realized by the mechanical structure design corresponding to the first linkage member 50, the second linkage member 60 and the driving member 40, and there may be multiple implementation methods.

[0053] In this way, the correlation between the opening and closing states of the first cover body 21 and the second cover body 22 is ensured by the mechanical transmission structure, and does not need to be ensured by the control logic of the control system. Thereby, it is ensured that the first cover body 21 and the second cover body 22 will not be in the open state at the same time, meeting the use requirements of industrial equipment. Even in the case of a controller failure or a power failure of the industrial equipment, the protective cover drive device 100 can still avoid the situation where the first opening 11 and the second opening 12 are opened at the same time, thereby enhancing the reliability of the protective cover drive device 100 and reducing the research and development and maintenance costs of the electronic control of industrial equipment. In addition, this embodiment uses a transmission structure of a drive member 40 with two linkage members to replace the technical solution that may need to control the two protective covers separately through multiple sets of drive devices, or may need to design a complex clutch mechanism to realize the separate movement of the two protective covers, thereby reducing the complexity of the protective cover drive device 100 and effectively reducing its production and maintenance costs.

[0054] Based on the previous embodiment, please refer to Figure 1 , Fig.12 and Fig.13 , the driving member 40 has a first position, an original position and a second position arranged in sequence along the positive direction of the preset path during the moving stroke. In this embodiment, the driving member 40 is slidably mounted on the housing 10. Preferably, the preset path extends along a straight line, that is, the driving member 40 is slidably mounted on the housing 10 in the direction of the preset path. It can be understood that in other embodiments, the preset path can also have other extension directions such as a broken line or a curve.

[0055] It can be understood that in other embodiments, the specific shape of the preset path is different according to the different structural designs of the driving mechanism 30. The working principle of the driving mechanism 30 is described below: when the driving member 40 is in the first position, the first cover 21 is in a closed state and the second cover 22 is in an open state; when the driving member 40 is in the original position, the first cover 21 and the second cover 22 are both in a closed state; when the driving member 40 is in the second position, the first cover 21 is in an open state and the second cover 22 is in a closed state.

[0056] That is to say, when the driving member 40 is driven to move forward along the preset path, it moves in the direction from the first position to the original position and then to the second position. Specifically, there are three situations: first, the driving member 40 moves from the original position to the second position, at which time the first opening 11 switches from closed to open while the second opening 12 remains closed; second, the driving member 40 moves from the first position to the original position, at which time the first opening 11 remains closed, while the second opening 12 switches from open to closed; third, the driving member 40 moves from the first position to the second position, at which time the second opening 12 first switches from open to closed, and then the first opening 11 switches from closed to open. In either case, the first opening 11 and the second opening 12 will not be opened at the same time.

[0057] On the contrary, when the driving member 40 is driven to move in the reverse direction along the preset path, it moves in the direction from the second position to the original position and then to the first position. Specifically, it can also include three situations: first, the driving member 40 moves from the original position to the first position, at which time the second opening 12 switches from closed to open while the first opening 11 remains closed; second, the driving member 40 moves from the second position to the original position, at which time the second opening 12 remains closed, while the first opening 11 switches from open to closed; third, the driving member 40 moves from the second position to the first position, at which time the first opening 11 switches from open to closed first, and then the second opening 12 switches from closed to open. In either case, the first opening 11 and the second opening 12 will not be opened at the same time.

[0058] In this embodiment, the driving member 40 has a first position, an original position and a second position arranged in sequence along the positive direction of the preset path during the moving stroke. This design enables the driving member 40 to pass through different positions in the process of being driven along the preset path, and the first cover body 21 and the second cover body 22 correspondingly switch their opening and closing states, thereby ensuring that the first opening 11 and the second opening 12 will not be opened at the same time regardless of whether after the active stroke of the driving member 40 ends or during the active stroke of the driving member 40, thereby further improving the safety and reliability of the protective cover driving device 100.

[0059] Furthermore, the driving mechanism 30 further includes a motor 31, which is connected to the driving member 40 in a driving manner. The specific connection method can be designed as needed. For example, when the preset path of the driving member 40 is a circular shape, the motor 31 can be coaxially connected to the driving member 40. Figure 8 and Fig. 9 , the preset path of the driving member 40 extends along a straight line, and it is provided with a rack 44 parallel to the preset path. The driving mechanism 30 also includes a driving gear 32 coaxially linked to the motor 31. The driving gear 32 meshes with the rack 44 to transfer the kinetic energy of the motor 31 to the driving member 40, driving it to move forward or reversely along the preset path. Specifically, when the motor 31 rotates forward, the driving member 40 moves forward along the preset path, and when the motor 31 rotates reversely, the driving member 40 moves reversely along the preset path. It should be noted that in this embodiment, the forward rotation of the motor 31 can be that its rotor rotates clockwise or counterclockwise, and the reverse rotation of the motor 31 is that its rotor rotates in the opposite direction to the forward rotation, which can be selected specifically as needed. In this embodiment, the forward or reverse movement control of the driving member 40 along the preset path is realized by switching the forward and reverse rotation actions of the motor 31. This design enables the protective cover driving device 100 to realize the electric opening and closing of the first cover body 21 and the second cover body 22, improve the user experience, and the control method is simple and reliable, and easy to maintain.

[0060] Based on the above examples, please continue to refer to Figures 1 to 4 The first cover 21 and the second cover 22 are installed on the outside of the housing 10, and the drive mechanism 30 is installed on the inside of the housing 10, which not only protects the drive mechanism 30 from the influence of the external environment, but also makes the electric cover drive device more compact and has a simple appearance.

Preferably, a slide rail 20 is also provided on the outer side of the housing 10, and the slide rail 20 is detachably connected to the fixed housing 10, and the second cover 22 side can be slidably inserted into the slide rail 20 to achieve a sliding connection with the housing 10.

[0064] In this embodiment, the above structure can realize that the first cover body 21 and the second cover body 22 can be slidably installed on the shell 10, and because the slide rail 20 is detachably connected to the shell 10, the slide rail 20 can be installed after the first cover body 21 and the second cover body 22 are respectively connected to the driving mechanism 30 on the inner side of the shell 10. The assembly sequence is simple and reasonable. The first cover body 21 and the second cover body 22 are limited in the inner and outer directions through the cooperation of the first gear bar 15, the second gear bar 16 and the slide rail 20. There is no need to rely on additional bolt structures, which ensures that the first cover body 21 and the second cover body 22 slide smoothly and greatly improves the assembly efficiency.

[0065] For further information, please refer to Fig.10 and Fig.11 The first linkage member 50 is a first connecting rod 51 rotatably mounted on the shell 10. The first connecting rod 51 has a first rotating end 511 rotatably connected to the shell 10, and a first free end 512 that rotates relative to the first rotating end 511. The first free end 512 is provided with a first guide structure 513, such as an elongated hole. The first guide member 211 guides and cooperates with the first guide structure 513, for example, it can be inserted into the first guide structure 513 in the shape of an elongated hole. A first driving part 514 for connecting the driving member 40 is provided between the first guide structure 513 and the first rotating end 511.

[0066] The second linkage member 60 is a second connecting rod 61 rotatably mounted on the shell 10. The second connecting rod 61 has a second rotating end 611 rotatably connected to the shell 10, and a second free end 612 that rotates relative to the second rotating end 611. The second free end 612 is provided with a second guide structure 613, such as an elongated hole. The second guide member 221 guides and cooperates with the second guide structure 613, for example, it can be inserted into the second guide structure 613 in the shape of an elongated hole. A second driving part 614 for connecting the driving member 40 is provided between the second guide structure 613 and the second rotating end 611.

[0067] In this embodiment, through the structural design of the first connecting rod 51 and the second connecting rod 61, the rotational movement of the first connecting rod 51 is converted into the sliding movement of the first cover body 21, and the driving force of the driving member 40 is transmitted to the sliding movement of the first cover body 21 by the first connecting rod 51, and the rotational movement of the second connecting rod 61 is converted into the sliding movement of the second cover body 22, and the driving force of the driving member 40 is transmitted to the sliding movement of the second cover body 22 by the second connecting rod 61. This design allows the driving force to be transmitted to the first cover body 21 and the second cover body 22 more smoothly and effectively, thereby improving the operating efficiency and stability of the entire driving device.

[0068] Preferred, please see Figure 5The first guide portion 111 and the second guide portion 112 are arranged side by side on the housing 10, and the first connecting rod 51 and the second connecting rod 61 are rotatably connected to the housing 10 through the same rotating connecting member 13. Preferably, the rotating connecting member 13 is integrally formed on the inner side of the housing 10, and the rotating connecting member 13 is arranged between the first guide portion 111 and the second guide portion 112. In this way, the number of parts of the driving mechanism 30 is reduced, thereby further reducing the cost, and the transmission structure is simpler and more reliable, reducing the failure rate and improving the assembly efficiency.

[0069] In a preferred embodiment, the driving member 40 is slidably mounted on the inner side of the housing 10, and the driving member 40 includes a guide plate 41 disposed at an interval from the housing 10 on the inner side of the housing 10, and the first connecting rod 51 and the second connecting rod 61 are disposed in the gap between the guide plate 41 and the housing 10, and a preset limiting structure 42 is disposed on the guide plate 41, which plays a guiding and limiting role for the first driving part 514 and the second driving part 614. Specifically, the preset limiting structure 42 can be a guide groove, a guide rail, a guide slot, etc., the first driving part 514 is a first guide pin 515 inserted in the preset limiting structure 42, and the second driving part 614 is a second guide pin 615 inserted in the preset limiting structure 42. In this embodiment, the sliding action of the driving member 40 is converted into the rotation action of the first connecting rod 51 and the second connecting rod 61 through the limiting cooperation of the preset limiting structure 42 disposed on the driving member 40 and the first guide pin 515 and the second guide pin 615. On the one hand, the transmission structure is simple and reliable, and the transmission efficiency of the driving mechanism 30 is high and the response speed is fast. On the other hand, the stacking of the guide plate 41 and the first connecting rod 51 and the second connecting rod 61 makes the overall structure of the protective cover driving device 100 more compact, with a smaller thickness and area, suitable for the special installation conditions of the protective cover driving device, and conducive to the overall assembly of industrial equipment.

[0070] For further information, see Fig. 9The preset limiting structure 42 includes a first guide segment 421, a second guide segment 422 and a third guide segment 423 which are adjacent to each other in sequence. The first guide segment 421, the second guide segment 422 and the third guide segment 423 all extend in a straight line, so that the preset limiting structure 42 extends in a broken line shape as a whole. The second guide segment 422 is parallel to the preset path, the first guide segment 421 extends obliquely from the end of the second guide segment 422 close to the first position toward the direction close to the first rotating end 511, and the third guide segment 423 extends obliquely from the end of the second guide segment 422 close to the second position toward the direction close to the second rotating end 611. When the driving member 40 is in the original position, the first guide pin 515 and the second guide pin 615 are both located in the second guide section 422; when the driving member 40 is in the first position, the first guide pin 515 is located in the second guide section 422, and the second guide pin 615 is located in the third guide section 423; when the driving member 40 is in the second position, the second guide pin 615 is located in the second guide section 422, and the first guide pin 515 is located in the first guide section 421.

[0071] In this embodiment, the second guide section 422 is arranged parallel to the preset path, so that when the first guide pin 515 or the second guide pin 615 slides along the second guide section 422, the first connecting rod 51 or the second connecting rod 61 to which it is connected does not rotate, so that when one of the first cover body 21 and the second cover body 22 performs a switching action, the other can be continuously kept closed. Thus, through a simple mechanical structure design, it is ensured that the first cover body 21 and the second cover body 22 will not be opened at the same time at any stage when the driving member 40 moves on the preset path. The structural design of the above-mentioned preset limiting structure 42 enables the driving member 40 to transition to different positions more smoothly during the movement process, thereby ensuring the stability and accuracy of the opening and closing actions of the first cover body 21 and the second cover body 22.

[0072] For further information, see Figure 5 , the housing 10 is provided with two limiting convex strips 14 protruding toward the inner side thereof, and the guide plate 41 is provided with flanges 43 and racks 44 parallel to the preset path on both sides of the preset limiting structure 42, respectively. The flanges 43 are bent toward the housing 10 and at least partially inserted between the two limiting convex strips 14, and the racks 44 are meshed with the driving gear 32. In this embodiment, the design of the two limiting convex strips 14 allows the driving member 40 to be more stably limited in the extension direction of the moving path during the movement process, so that the movement process of the driving member 40 is more stable, and the mutual wear of the parts of the driving mechanism 30 is reduced, thereby improving the durability and reliability of the driving mechanism 30, and the assembly method of the flanges 43 and the two limiting convex strips 14 is simple and reliable, which improves the assembly efficiency of the protective cover driving device 100.

Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
