[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0065] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0066] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0067] The present application proposes a range hood, combined with Figure 1 , Figure 6 as well as Figures 11 to 17 As shown, the range hood includes a smoke collecting module 100, wherein the smoke collecting module 100 includes an opening and closing panel module 1000 and a main body, the opening and closing panel module 1000 includes a guide plate 1100, a driving mechanism 1200 and an opening and closing panel 1500, the guide plate 1100 is detachably connected to the main body, and the guide plate 1100 is provided with an air inlet 1110, the driving mechanism 1200 is provided on the guide plate 1100, and the opening and closing panel 1500 is connected and fixed to the driving mechanism 1200, and the opening and closing panel 1500 can move under the drive of the driving mechanism 1200, thereby realizing the closing and opening of the air inlet 1110. The opening and closing panel module 1000 is formed by combining the guide plate 1100, the driving mechanism 1200 and the opening and closing panel 1500. When the driving mechanism 1200 fails and causes the opening and closing panel 1500 to be in a state of closing the air inlet 1110, the entire opening and closing panel module 1000 can be disassembled by releasing the connection between the guide plate 1100 and the main body, thereby facilitating the maintenance of the driving mechanism 1200.

[0068] Specifically, the range hood includes a smoke collecting module 100 and an exhaust module 200. Figure 1 , Figure 3 and Figure 4As shown, the exhaust module 200 is installed above the smoke collection module 100. The smoke collection module 100 is used to gather the oil smoke, and the exhaust module 200 is used to provide power for exhaust air. Generally speaking, the exhaust module 200 has a fan. When the fan is working, the oil smoke first enters the smoke collection module 100 and then is transmitted to the exhaust module 200, and is finally discharged to the outside through the fan.

[0069] The smoke collecting module 100 includes an opening and closing panel module 1000 and a main body. The main body constitutes most of the structure of the smoke collecting module 100. For example, the main body includes a top plate 4100, a rear plate (not shown in the figure), a side plate 4200 and a bottom plate 4400. The so-called front, back, left and right directions are based on the installation of the range hood in the kitchen. The side of the range hood facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, and the side corresponding to the right hand is the right. The top plate 4100 has an opening (not shown in the figure), and the exhaust module 200 is installed at the opening of the top plate 4100. Along the roughly horizontal direction, the top plate 4100 has a larger size relative to the exhaust module 200 to increase the smoke collecting range of the smoke collecting module 100. Side panels 4200 are arranged on both sides of the top panel 4100, and the back panel is located behind the top panel 4100 and the side panels 4200. The top panel 4100 and the back panel can be formed by bending the same panel, and then the side panels 4200 are connected thereto, or the top panel 4100 and the side panels 4200 are formed by bending the same panel, and then the back panel is connected thereto, or the back panel and the side panels 4200 are formed by bending the same panel, and then the top panel 4100 is connected thereto. The bottom panel 4400 is connected to the bottom of the back panel and the side panels 4200. Through the cooperation of the top panel 4100, the back panel, the side panels 4200 and the bottom panel 4400, the smoke collecting module 100 is roughly triangular when viewed from the left or right side.

[0070] The guide plate 1100 is arranged in front of the rear plate and between the side plates 4200 on the left and right sides. The guide plate 1100 is provided with an air inlet 1110. The top plate 4100, the side plate 4200, the rear plate and the guide plate 1100 enclose a larger internal space. When the exhaust module 200 is working, the oil smoke enters the internal space from the air inlet 1110, and then enters the exhaust module 200, and is discharged to the outside by the exhaust module 200. The opening and closing panel 1500 needs to be configured to be movable, for example, it can be moved by being driven by the driving mechanism 1200, so that the air inlet 1110 can be closed and opened. When the range hood is needed, the driving mechanism 1200 drives the opening and closing panel 1500 to move, so that the opening and closing panel 1500 opens the air inlet 1110, thereby achieving the extraction of oil smoke. When the range hood is not needed, the driving mechanism 1200 drives the opening and closing panel 1500 to move, so that the opening and closing panel 1500 closes the air inlet 1110.

[0071] In the related art, the driving mechanism 1200 is installed on the main body, and then the opening and closing panel 1500 is installed on the driving mechanism 1200. When the opening and closing panel 1500 is in a state of closing the air inlet 1110, the opening and closing panel 1500 blocks the driving mechanism 1200. If the driving mechanism 1200 fails, it is difficult to remove the opening and closing panel 1500 from the driving mechanism 1200 because the opening and closing panel 1500 and the driving mechanism 1200 are connected to each other. When the driving mechanism 1200 fails, the opening and closing panel 1500 blocks the driving mechanism 1200 and cannot move. Therefore, the operator cannot operate to release the connection between the opening and closing panel 1500 and the driving mechanism 1200. In this case, the operator cannot repair the driving mechanism 1200, and even needs to disassemble the entire range hood to repair the driving mechanism 1200, which is extremely troublesome.

[0072] To this end, in this embodiment, the opening and closing panel 1500, the driving mechanism 1200 and the guide plate 1100 are combined into a whole to form an opening and closing panel module 1000. Through modularization, in the later stage, if the driving mechanism 1200 fails, even if the opening and closing panel 1500 is in a state of closing the air inlet 1110, it is only necessary to release the connection between the guide plate 1100 and the main body, and then the entire opening and closing panel module 1000 can be disassembled and placed on a working plane to inspect the driving mechanism 1200. It is not necessary to disassemble the entire range hood, which greatly improves the convenience of maintenance. It can be understood that there are many ways to detachably connect the guide plate 1100 and the main body, such as screw connection, snap connection, etc. Generally speaking, in order to simplify the detachable connection method and have a lower cost, a screw connection method is used.

[0073] In some embodiments of the present application, Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the guide plate 1100 is provided with a first fastening portion 1120, and the guide plate 1100 is detachably connected to the main body through the first fastening portion 1120, and the smoke collecting module 100 includes a covering component 2000, and the covering component 2000 can both cover the first fastening portion 1120 and expose the first fastening portion 1120. Through the provision of the covering component 2000, it is possible to avoid exposure of the first fastening portion 1120, thereby improving the aesthetics, and it is also possible to facilitate the disassembly of the guide plate 1100 by exposing the first fastening portion 1120.

[0074] Specifically, the guide plate 1100 is fixed to the main body by a detachable connection, so a first fastening portion 1120 is provided on the guide plate 1100, and a detachable connection between the guide plate 1100 and the main body is achieved through the first fastening portion 1120. For example, the first fastening portion 1120 is a fastening hole, and the fastening hole needs to be fixed to the main body by screws to achieve the fixation of the guide plate 1100. The connection between the first fastening portion 1120 and the main body can be released by loosening the screws, so that the guide plate 1100 can be removed.

[0075] When the range hood is in normal use, it is not desirable to expose the first fastening portion 1120, so as to improve the aesthetics of the product. For this purpose, a covering member 2000 is provided, and the covering member 2000 has at least two functions, which can cover the first fastening portion 1120 and also expose the first fastening portion 1120. When the range hood is in normal use, the covering member 2000 can cover the first fastening portion 1120 to prevent the first fastening portion 1120 from being exposed. When the opening and closing panel module 1000 needs to be disassembled, the covering member 2000 exposes the first fastening portion 1120, so that the operator can easily release the connection between the first fastening portion 1120 and the main body.

[0076] It is understandable that the covering member 2000 can both cover and expose the first fastening portion 1120, that is, the covering member 2000 needs to be configured to be positionally changeable, for example, the covering member 2000 is detachable, or the covering member 2000 is movable, so that the first fastening portion 1120 can be exposed and covered by changing the state of the covering member 2000. It is understandable that the covering member 2000 needs to adopt a relatively simple method for the operator to change the state.

[0077] For example, in some embodiments of the present application, Figures 6 to 10 As shown, the covering panel includes an upper panel 2100 and a control panel 2200. The upper panel 2100 is arranged above the opening and closing panel 1500. The upper panel 2100 is provided with a second fastening portion 2110. The second fastening portion 2110 is used for detachable connection with other components, for example, detachable connection with the main body, so as to achieve the installation and fixation of the upper panel 2100. When the upper panel 2100 is installed in place, the upper panel 2100 covers the first fastening portion 1120 to avoid exposure of the first fastening portion 1120. The control panel 2200 is arranged above the upper panel 2100. The control panel 2200 is configured to be pluggable. When the control panel 2200 is installed in place, the control panel 2200 blocks the second fastening portion 2110 to avoid exposure of the second fastening portion 2110.

[0078] The opening and closing panel 1500 is generally arranged at the front end of the main body, and the upper panel 2100 and the control panel 2200 are also arranged at the front end of the main body, forming at least part of the front surface of the smoke collecting module 100. The control panel 2200 controls the range hood, and the range hood can be turned on and off, function selection, operating parameter display, etc. through the control panel 2200. The upper panel 2100 is arranged between the control panel 2200 and the opening and closing panel 1500, and is arranged in accordance with the shape of the smoke collecting module 100, for example, the upper panel 2100 is arranged to be inclined from front to back and from top to bottom. The installation of the upper panel 2100 also adopts a detachable connection method. For example, the second fastening part 2110 is also a fastening hole, and the detachable connection with the main body is achieved by screws. In this way, the upper panel 2100 can be fastened as well as removed. When the upper panel 2100 is installed in place, the upper panel 2100 can block the first fastening part 1120, while the blocking of the second fastening part 2110 is achieved through the control panel 2200.

[0079] The control panel 2200 is installed in a pluggable connection manner, that is, when the control panel 2200 needs to be installed, the control panel 2200 is connected and fixed by plugging, and when the control panel 2200 needs to be removed, the control panel 2200 is removed by pulling out. By designing the control panel 2200 to be installed in a pluggable manner, it is convenient to remove, and the operator can remove the control panel 2200 even without the aid of tools. In addition, by plugging, when the control panel 2200 is installed in place, the pluggable structure can be covered to avoid exposure.

[0080] The disassembly process of the opening and closing panel module 1000 is explained by taking the example that both the first fastening part 1120 and the second fastening part 2110 are fastening holes and need to be connected by screws: a pulling force is applied to the control panel 2200, and the control panel 2200 can be easily removed without the need for tools. After removing the control panel 2200, the second fastening part 2110 is exposed, and the screws connected to the second fastening part 2110 are loosened, so that the upper panel 2100 can be removed. After removing the upper panel 2100, the first fastening part 1120 is exposed, and the screws connected to the first fastening part 1120 are loosened, and the opening and closing panel module 1000 can be disassembled, thereby facilitating the inspection and maintenance of the driving mechanism 1200.

[0081] Further, the control panel 2200 realizes plug-in connection by the following method, combining Fig. 9 , Fig.10 , Fig.23 , Fig.24 , Fig.25 and Fig.26As shown, in some embodiments of the present application, the control panel 2200 is provided with a spring buckle 2220, and the upper panel 2100 or the main body is provided with a socket 2120, and the spring buckle 2220 and the socket 2120 are mutually snap-connected, which is convenient and fast and has high installation stability.

[0082] When the control panel 2200 needs to be installed, the snap 2220 is aligned with the socket 2120 and inserted, so as to be snapped into the socket 2120. When the control panel 2200 needs to be removed, a force is applied to the control panel 2200 to drive the snap 2220 to be pulled out of the socket 2120. There are many ways to set the snap 2220. For example, the control panel 2200 is provided with a base 2210, the base 2210 and the control panel 2200 are bonded together, and the snap 2220 is set on the base 2210. The snap 2220 can be integrally formed with the base 2210 and relatively bent, and the snap 2220 extends from the base 2210 away from the control panel 2200.

[0083] Combination Fig.26 As shown, spring buckles 2220 are respectively provided on opposite sides of the base 2210, and the spring buckles 2220 on both sides are bent toward each other by a certain length. When installing the control panel 2200, the spring buckles 2220 on the opposite sides are inserted into the corresponding plug holes 2120. The spring buckles 2220 undergo elastic deformation during the insertion process of the plug holes 2120. When the spring buckle 2220 is inserted into place, the spring buckle 2220 is reset, so that the spring buckle 2220 and the plug hole 2120 are mutually engaged, and the installation of the control panel 2200 is realized. When the control panel 2200 needs to be disassembled, the spring buckle 2220 is pulled out of the plug hole 2120, and the spring buckle 2220 undergoes elastic deformation during the pulling process, until it is completely out of the plug hole 2120 and resets.

[0084] In some embodiments of the present application, Fig.11 As shown, the guide plate 1100 is fastened and installed by the first fastening part 1120. In order to facilitate the detachable connection operation of the first fastening part 1120, a hook 1130 is provided on the guide plate 1100, and a hanging hole (not shown in the figure) is provided on the main body. When installing the guide plate 1100, the guide plate 1100 is operated to move so that the hook 1130 is hung in the hanging hole. Through the mutual cooperation of the hook 1130 and the hanging hole, the guide plate 1100 is initially positioned and installed on the main body, which facilitates the subsequent connection operation of the first fastening part 1120. For example, after the guide plate 1100 is initially positioned and installed by the hook 1130 and the hanging hole, the first fastening part 1120 can be more conveniently screwed. When disassembling and repairing, the screws on the first fastening part 1120 can be loosened without causing the guide plate 1100 to fall off immediately, thereby improving safety.

[0085] In some embodiments of the present application, Fig.23 As shown, the same is true for the installation of the upper panel 2100. The upper panel 2100 is fastened and installed by the second fastening part 2110. In order to facilitate the detachable connection operation of the second fastening part 2110, a hook 2130 is provided on the upper panel 2100, and a hanging hole is provided on the main body (not shown in the figure). When installing the upper panel 2100, the upper panel 2100 is operated to move so that the hook 2130 is hung in the hanging hole. Through the mutual cooperation of the hook 2130 and the hanging hole, the upper panel 2100 is initially positioned and installed, which facilitates the subsequent connection operation of the second fastening part 2110. For example, after the upper panel 2100 is initially positioned and installed by the hook 2130 and the hanging hole, the second fastening part 2110 can be more conveniently screwed. When disassembling and repairing, loosening the screws on the second fastening part 2110 will not cause the upper panel 2100 to fall off immediately, thereby improving safety.

[0086] Furthermore, combined with Figure 4 , Figure 5 and Fig.13 As shown, in some embodiments of the present application, the covering component 2000 also includes a lower panel 2300, and the lower panel 2300 is rotatably arranged to cover and reveal the liquid storage box 4700. At the same time, the lower panel 2300 can also cover and reveal the first fastening portion 1120.

[0087] Specifically, during the process of the range hood sucking oil fumes, the oil mist particles in the oil fume will adhere to the corresponding parts wherever they pass through to form oil stains, and the oil stains will flow downward under the action of gravity. In addition, when the range hood is steam-cleaned, the condensed water formed will also flow downward. In order to facilitate the collection of oil stains and condensed water, it is necessary to set a liquid storage box 4700 at the lower position of the range hood. The liquid storage box 4700 includes a water box 4720 and an oil box 4710. The water box 4720 is used to store water for generating steam, and the oil box 4710 is used to store oil stains and condensed water.

[0088] In this embodiment, the water box 4720 and the oil box 4710 are arranged on the main body, and the water box 4720 and the oil box 4710 are shielded by the lower panel 2300. For example, when the oil box 4710 needs to be cleaned or the water box 4720 needs to be filled with water, the lower panel 2300 is rotated from top to bottom so that the oil box 4710 and the water box 4720 are exposed, and the user can take out the oil box 4710 and the water box 4720. When the cleaning of the oil box 4710 or the filling of the water box 4720 is completed, the lower panel 2300 can be rotated from bottom to top to shield the oil box 4710 and the water box 4720, thereby improving the aesthetics. Even, a spring can be provided to generate force for the rotation of the lower panel 2300, so that the lower panel 2300 is in a state of shielding the oil box 4710 and the water box 4720. Based on this, the rotatable setting of the lower panel 2300 is also used to realize the covering and exposure of the first fastening part 1120. That is to say, the first fastening part 1120 is provided on the upper and lower sides of the guide plate 1100. This makes the installation of the guide plate 1100 more stable. When it is necessary to disassemble the opening and closing panel module 1000, it is necessary to loosen the connection of the first fastening part 1120 on the upper side of the guide plate 1100 and the connection of the first fastening part 1120 on the lower side of the guide plate 1100 respectively.

[0089] In some embodiments of the present application, Figures 11 to 17 As shown, the driving mechanism 1200 includes a driver 1300 and a connecting rod assembly 1400, the driver 1300 is connected to the connecting rod assembly 1400, the connecting rod assembly 1400 is connected to the opening and closing panel 1500, and the driver 1300 drives the opening and closing panel 1500 by driving the connecting rod assembly 1400, so that the opening and closing panel 1500 opens and closes the air inlet 1110.

[0090] For example, when the range hood is working, the driver 1300 drives the connecting rod assembly 1400 to move, and the connecting rod assembly 1400 drives the opening and closing panel 1500 to rotate from bottom to top to open the air inlet 1110. When the range hood stops working, the driver 1300 drives the connecting rod assembly 1400 to move, and the connecting rod assembly 1400 drives the opening and closing panel 1500 to rotate from top to bottom to close the air inlet 1110. Through the arrangement of the connecting rod assembly 1400, the rotation of the opening and closing panel 1500 is not around the same rotation axis, and the opening and closing panel 1500 will be away from the guide plate 1100 during the rotation process, so as to prevent the interference between the rotation of the opening and closing panel 1500 and the guide plate 1100.

[0091] Specifically, the connecting rod assembly 1400 includes a mounting seat 1410, a first connecting member 1420, a second connecting member 1430 and a third connecting member 1440. The mounting seat 1410 is arranged on the guide plate 1100. The mounting seat 1410 can be clamped, screwed or welded to the guide plate 1100 to achieve mutual fixation with the guide plate 1100. In order to avoid the mounting seat 1410 from being exposed, the mounting seat 1410 is arranged on the inner surface (rear surface) of the guide plate 1100. The first connecting member 1420 is in the shape of a rod, and is defined as a first connecting rod 1420. One end of the first connecting rod 1420 is connected to the driving shaft 1310 of the driver 1300, so that the driver 1300 can drive the first connecting rod 1420 to rotate, and the other end of the first connecting rod 1420 is rotatably connected to the second connecting member 1430. The second connecting rod 1430 is also in the shape of a rod, and one end of the second connecting rod 1430 is rotatably connected to the other end of the first connecting rod 1420, and the other end of the second connecting rod 1430 is rotatably connected to the third connecting member 1440. The third connecting member 1440 is generally in the shape of an irregular flat plate, defined as the third connecting plate 1440, and the connection between the opening and closing panel 1500 and the connecting rod assembly 1400 is connected to the third connecting plate 1440, and the third connecting plate 1440 has a first connecting point 1441 and a second connecting point 1442, and the first connecting point 1441 is rotatably connected to the other end of the second connecting rod 1430, and the second connecting point 1442 is rotatably connected to the mounting seat 1410, so as to form a four-link structure, so that the rotation of the opening and closing panel 1500 can avoid interference with the guide plate 1100.

[0092] It is understandable that the driver 1300 needs to be fixed in one position, which is the basis for driving the connecting rod assembly 1400. For example, the driver 1300 can be connected to the guide plate 1100, or the driver 1300 can be connected to the mounting base 1410. In the present embodiment, preferably, the driver 1300 is connected to the mounting base 1410, so that the driver 1300 and the connecting rod assembly 1400 can form a module, which makes it more convenient for the driver 1300 and the connecting rod assembly 1400 to cooperate with each other, and is beneficial to improving the installation efficiency of the opening and closing panel module 1000.

[0093] Furthermore, combined with Fig.17 As shown, in some embodiments of the present application, connecting rod assemblies 1400 are respectively provided on the opposite sides of the guide plate 1100, and the driver 1300 is only provided to cooperate with the connecting rod assembly 1400 on one side. In this way, the normal driving of the opening and closing panel 1500 can be achieved, so that the opening and closing panel 1500 can close and open the air inlet 1110, and the cost can also be reduced.

[0094] Specifically, along the left and right directions, the smoke collecting module 100 has a certain length to achieve a large range of oil smoke gathering, and the air inlet 1110 includes two, arranged along the left and right directions, so the opening and closing panel 1500 also has a certain length along the left and right directions, so as to achieve the shielding and exposure of the two air inlets 1110. In order to make the opening and closing panel 1500 more stable, the connecting rod assembly 1400 will be respectively arranged on the left and right sides of the opening and closing panel 1500. By setting a driver 1300, it is sufficient to provide sufficient power to make the opening and closing panel 1500 move, so the driver 1300 only cooperates with the connecting rod assembly 1400 on one side, and the connecting rod assembly 1400 on the other side does not need to be provided with the driver 1300, so as to reduce the cost. It is understandable that in the connecting rod assembly 1400 on the other side where the driver 1300 is not provided, the first connecting member 1420 and the mounting seat 1410 are rotatably connected.

[0095] In some embodiments of the present application, in order to facilitate the installation of the opening and closing panel 1500 and the third connecting member 1440 together, Fig.17 , Fig.18 , Fig.21 and Fig. 22 As shown, mounting brackets 1510 are respectively provided on opposite sides of the opening and closing panel 1500. For example, the mounting brackets 1510 are fixed to the inner surface (rear surface) of the opening and closing panel 1500 by gluing. The mounting bracket 1510 has a plug-in portion 1511, and the third connecting member 1440 is provided with a positioning hole 1443. When the opening and closing panel 1500 needs to be installed on the third connecting member 1440, the plug-in portion 1511 is aligned with the positioning hole 1443 and snapped into place, thereby realizing the preliminary positioning and installation of the opening and closing panel 1500. For example, during installation, the mounting bracket 1510 on the left is moved between the third connecting members 1440 on the left and right sides, the plug-in portion 1511 of the mounting bracket 1510 on the left is aligned with the positioning hole 1443 of the third connecting member 1440 on the left and inserted, and then force is applied to cause the third connecting member 1440 on the right to deform to a certain extent, and then the plug-in portion 1511 of the mounting bracket 1510 on the right is aligned with the positioning hole 1443 of the third connecting member 1440 on the right and inserted, and then the third connecting member 1440 on the right is reset. In this way, the preliminary positioning and installation of the opening and closing panel 1500 is achieved through the cooperation of the positioning hole 1443 and the plug-in portion 1511, thereby facilitating the subsequent further tightening of the third connecting member 1440 and the mounting bracket 1510 by means of screws.

[0096] In some embodiments of the present application, Figure 1 , Figure 2 , Fig.19 and Fig. 20As shown, the smoke collecting module 100 further includes a decorative strip 3000 . By connecting the decorative strip 3000 and the guide plate 1100 , the structural strength of the guide plate 1100 is enhanced, so that the installation of the driving mechanism 1200 is more stable.

[0097] The so-called decorative strip 3000 can be in a visible state and within the user's field of vision, and can serve as a decoration. The decorative strip 3000 can be subjected to a variety of surface treatments to enhance the aesthetics of the range hood. Since the driving mechanism 1200 is installed on the guide plate 1100, the driving mechanism 1200 has a certain weight, and the driving mechanism 1200 is connected to the opening and closing panel 1500, and the weight of the opening and closing panel 1500 is also applied to the guide plate 1100, the guide plate 1100 bears the weight of the driving mechanism 1200 and the opening and closing panel 1500. Generally speaking, the guide plate 1100 is a flat plate, and the weight of the driving mechanism 1200 and the opening and closing panel 1500 can easily cause the guide plate 1100 to partially shake, thereby causing the opening and closing panel 1500 to shake. Unstable movement. Of course, the thickness of the guide plate 1100 can be increased to solve this problem, but this will make the guide plate 1100 difficult to process and lead to an increase in cost. For this reason, in this embodiment, a decorative strip 3000 is added. The decorative strip 3000 not only plays a decorative role, but the decorative strip 3000 is also connected to the guide plate 1100. For example, the decorative strip 3000 and the guide plate 1100 are fitted and connected together. This can enhance the structural strength of the guide plate 1100, thereby more effectively supporting the drive mechanism 1200 and the opening and closing panel 1500.

[0098] It is understandable that the decorative strip 3000 and the guide plate 1100 can be connected in a variety of ways, such as screw connection, clamping connection, welding, etc. The decorative strip 3000 can be specifically connected to the first fastening portion 1120 of the guide plate 1100, so that when the upper panel 2100 covers the first fastening portion 1120, the portion where the decorative strip 3000 and the first fastening portion 1120 are connected can be simultaneously covered.

[0099] Combination Fig.12 , Fig.19 and Fig. 20 As shown, the decorative strip 3000 is provided with a sink 3100, and the setting of the sink 3100 enhances the structural strength of the decorative strip 3000. When the sink 3100 and the guide plate 1100 are fitted and connected, the structural strength of the guide plate 1100 can be further improved. For example, a hole 3110 is provided in the sink 3100, and the first fastening portion 1120 of the guide plate 1100 is also a fastening hole. The hole 3110 of the sink 3100 corresponds to the first fastening portion 1120, and the decorative strip 3000 and the guide plate 1100 are fixed to each other by screws. When the upper panel 2100 blocks the first fastening portion 1120, the hole 3110 can be blocked synchronously.

[0100] Furthermore, combined with Fig.12 and Fig.14 As shown, the mounting seat 1410 of the driving mechanism 1200, the guide plate 1100 and the decorative strip 3000 are connected to each other, thus forming a three-layer stacked structure, which greatly improves the structural strength of the guide plate 1100. For example, the mounting seat 1410 is arranged on the inner surface (rear surface) of the guide plate 1100, and the decorative strip 3000 is arranged on the outer surface (front surface) of the guide plate 1100. The mounting seat 1410 and the decorative strip 3000 clamp the guide plate 1100, and the three can be fastened by screws, which is conducive to improving the structural strength, so that the driving mechanism 1200 drives the opening and closing panel 1500 to move more smoothly.

[0101] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
