Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of transportation machinery, and in particular to a tarpaulin rack with an anti-deformation function, a truck tarpaulin system and a novel carriage. Background Art

[0002] During cargo transportation or storage, tarpaulins are often used to cover cargo boxes to prevent them from being blown away by the wind or to prevent dust and other pollutants from escaping into the air, potentially polluting the environment. Tarpaulins are traditionally used to cover cargo boxes, a labor-intensive and time-consuming process that often requires multiple personnel. This process is inefficient and struggles to meet the growing demand for freight. Furthermore, tarpaulins sometimes require workers to climb onto the train compartments, which not only places a heavy burden on workers but is also dangerous and increases the risk of injury.

[0003] To address this issue, automated tarpaulin systems have emerged on the market, replacing manual tarpaulin application. Typically installed on the exterior of a truck compartment, these systems consist of a connected tarpaulin cover and tarpaulin frame. A motor drives the tarpaulin cover to follow the contours of the tarpaulin frame, allowing the tarpaulin to open and close. The tarpaulin frame typically consists of a fixedly connected horizontal beam and side beams. The side beams are parallel to the vertical beams of the compartment, while the horizontal beams are perpendicular to them.

[0004] When the car body is squeezed and deformed, this deformation can be transmitted to the tarpaulin frame in contact with the car body, causing the side beams or cross beams to also deform. This deformation of the side beams or cross beams not only affects the structural stability of the tarpaulin frame itself, but also significantly affects the smooth movement of the tarpaulin cover relative to the tarpaulin frame, preventing the tarpaulin cover from smoothly following the contours of the tarpaulin frame, thereby increasing the possibility of failure of the automatic tarpaulin mechanism. Utility Model Content

[0005] In view of the above problems, the embodiments of the present invention provide a tarpaulin frame, a truck tarpaulin system and a new type of carriage with anti-deformation function to solve the problem that the tarpaulin frame is deformed due to deformation of the carriage, which in turn causes the automatic tarpaulin device to fail.

[0011] A mounting seat matching the fixing frame is formed on the other of the first contact surface and the second contact surface and has a mounting groove opening toward the fixing frame;

[0012] The two ends of the guide member can pass through the buffer space and be connected to the side walls of the mounting groove respectively. In response to the deformation of the tarpaulin frame, the guide member can limit the relative displacement between the fixing frame and the mounting seat in the buffer space.

[0013] In some embodiments, the fixing frame and the vertical section are integrally formed;

[0014] The mounting base and the stake are integrally formed.

[0015] In some embodiments, the fixing frame is provided with a fixing hole, and one of the first contact surface and the second contact surface is provided with an assembly hole; the mounting seat is provided with a mounting hole, and the other of the first contact surface and the second contact surface is provided with a connection hole;

[0016] The guide assembly also includes:

[0017] The fastener can pass through the fixing hole to cooperate with the assembly hole, and pass through the mounting hole to cooperate with the connecting hole, so as to respectively realize the detachable connection between the fixing frame and the cross bar, and the mounting seat and the pile.

[0018] In some embodiments, the guide member is a roller, and the roller comprises:

[0019] The roller shaft has two ends fixedly connected to the side walls of the mounting groove;

[0020] The roller body is sleeved on the outside of the roller shaft, and the edge of the roller body is provided with a pair of stop parts extending along its radial direction, and the distance between the pair of stop parts is not less than the width of the fixed frame.

[0021] In some embodiments, there are two rollers, which are respectively arranged on both sides of the center line of the pile.

[0022] In some embodiments, the ratio of the length of the fixing frame to the width of the vertical segment is between 1.5-1.

[0023] In some embodiments, there are two horizontal bars and four vertical stakes, and the four vertical stakes correspond to two horizontal bars in pairs;

[0024] There are two guide assemblies, which are respectively arranged on both sides of any horizontal bar.

[0025] In some embodiments, there are two horizontal bars and four vertical stakes, and the four vertical stakes correspond to two horizontal bars in pairs;

[0026] There are four guide assemblies, which are respectively arranged on both sides of the two horizontal bars.

[0027] In a second aspect, an embodiment of the present invention also provides a truck tarpaulin system, comprising a tarpaulin cover and a tarpaulin frame as described above, wherein the cross bar is provided with a guide member, and the tarpaulin cover is provided with a transmission member, and the transmission member and the guide member cooperate to enable the tarpaulin cover to move along the contour of the tarpaulin frame.

[0029] Due to the adoption of the above technical solution, the technical effects achieved by the present invention are as follows:

[0030] First, the present invention provides a tarpaulin frame with an anti-deformation function, comprising a horizontal bar, a vertical stake, and a guide assembly. The guide assembly comprises a fixed frame, a mounting seat, and a guide member. One of the fixed frame and the mounting seat is disposed on a first contact surface, while the other is disposed on a second contact surface. The guide member cooperates with the fixed frame to confine the displacement between the fixed frame and the mounting seat within a buffer space. This arrangement allows the horizontal bar and the vertical stake to move relative to each other when subjected to external force, dissipating the external force within the buffer space. This greatly reduces any stress that may arise between the two, minimizing any adverse deformation of the tarpaulin frame and thereby ensuring the stability of the tarpaulin frame's overall structure.

[0031] In addition, the truck tarpaulin system provided by the present invention, through the arrangement of the above-mentioned tarpaulin frame, helps to ensure the smoothness and reliability of the movement of the tarpaulin cover relative to the tarpaulin frame, so that the tarpaulin cover can move smoothly along the contour of the tarpaulin frame in more scenarios, greatly reducing the possibility of failure of the truck tarpaulin system.

[0032] Furthermore, the novel carriage provided by the present invention comprises a carriage body and a tarpaulin system, wherein the tarpaulin system further comprises a tarpaulin cover and the aforementioned tarpaulin frame. The provision of the aforementioned tarpaulin frame can largely prevent the tarpaulin system from failing when the carriage body deforms, thereby improving the overall stability and reliability of the carriage.

[0051] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the accompanying drawings show exemplary embodiments of the present invention, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0052] Reference Figures 1-6 As shown, an embodiment of the present invention provides a tarpaulin rack with an anti-deformation function, including a horizontal bar 100 and a stake 200 located below the horizontal bar 100, and a guide assembly 300 connected to the horizontal bar 100 and the stake 200 respectively. Among them, the horizontal bar 100 has a horizontal section 120 and a vertical section 130, and a bending section 140 respectively connected to the horizontal section 120 and the vertical section 130, and the bottom end of the vertical section 130 has a first contact surface 110, and the top end of the stake 200 has a second contact surface 210; the guide assembly 300 includes a fixed frame 310, a mounting seat 320 and a guide member 330, the fixed frame 310 is formed on one of the first contact surface 110 and the second contact surface 210, and has a through buffer space 311; the mounting seat 320 matches the fixed frame 310, and is formed on the other of the first contact surface 110 and the second contact surface 210, and has a mounting groove 321 opening toward the fixed frame 310; the two ends of the guide member 330 can pass through the buffer space 311 and are respectively connected to the side walls of the mounting groove 321, and in response to the deformation of the tarpaulin frame, the guide member 330 can limit the relative displacement between the fixed frame 310 and the mounting seat 320 to the buffer space 311.

[0053] It should be noted that the tarpaulin rack in the present application is usually placed against the outside of the truck compartment. Since there are many different types of truck compartments, such as gate truck compartments, flatbed truck compartments, side curtain truck compartments and dump truck compartments, and the sizes, specifications and structures of different types of truck compartments are more or less different, when the user installs the tarpaulin rack on different types of truck compartments, the user can appropriately adjust the sizes and specifications of components such as the cross bar 100, stakes 200, and even the guide assembly 300 in the tarpaulin rack according to the parameters of different types of truck compartments. This application does not limit the specific sizes and specifications of each component in the tarpaulin rack.

[0054] It should also be noted that although the tarpaulin rack in this application is generally compatible with a truck compartment, this does not mean that the tarpaulin rack has a unique structure. For example, the tarpaulin rack may only include a horizontal bar 100 and a vertical stake 200, and the horizontal bar 100 may be fixedly mounted on the fence of the truck compartment, and the vertical stake 200 is arranged parallel to the side beams of the truck compartment; or the tarpaulin rack may also include a horizontal bar 100, side bars, and vertical stakes 200, and the horizontal bar 100 and the side bars are connected to form a closed frame structure, and the horizontal bar 100 and the side bars may be fixedly mounted on the fence of the truck compartment, and the vertical stakes 200 are parallel to the side beams of the truck compartment. This application does not limit the specific structure of the tarpaulin rack.

[0055] Furthermore, the arrangement of the bent sections 140 in the horizontal bar 100 of the aforementioned structure allows the tarpaulin frame, when mated with the tarpaulin cover 400 described below, to more smoothly follow the contours of the tarpaulin frame. Furthermore, the bent sections 140 can disperse the stress generated on the vertical sections 130 to a certain extent, thereby enhancing the structural strength and stability of the horizontal bar 100. Furthermore, the horizontal bar 100 of this structure has a more aesthetically pleasing appearance.

[0056] In addition, the fixing frame 310 and the mounting seat 320 in the guide assembly 300 are respectively formed on the first contact surface 110 and the second contact surface 210, wherein the fixing frame 310 and the mounting seat 320 can be arranged on the horizontal bar 100 and the pile 200 in various ways. For example, the fixing frame 310 and the horizontal bar 100 are integrally formed, and the mounting seat 320 and the pile 200 are integrally formed; or the fixing frame 310 and the pile 200 are integrally formed, and the mounting seat 320 and the horizontal bar 100 are integrally formed; or, the fixing frame 310 and the horizontal bar 100 are detachably connected, and the mounting seat 320 and the pile 200 are detachably connected; or, the fixing frame 310 and the pile 200 are detachably connected, and the mounting seat 320 and the horizontal bar 100 are detachably connected; even, the fixing frame 310 and the horizontal bar 100 are integrally formed, and the mounting seat 320 and the pile 200 are detachably connected; or, the fixing frame 310 and the horizontal bar 100 are detachably connected, and the mounting seat 320 and the pile 200 are integrally formed. This application does not limit this.

[0057] It is understood that the buffer space 311 formed in the fixed frame 310 primarily limits the relative displacement between the fixed frame 310 and the mounting base 320 by cooperating with the guide member 330. Furthermore, the shape and structure of the buffer space 311 can be adjusted to accommodate the different structures of the guide member 330. For example, when the guide member 330 is a roller, the buffer space 311 can be an arcuate rolling groove; when the guide member 330 is a slider, the buffer space 311 can be a rectangular slide groove that cooperates with the slider; alternatively, the guide member 330 can be a slider made of a material with a low friction coefficient (such as nylon, polyethylene, etc.), and the buffer space 311 can be a slide rail that matches the shape of the slider. Given that the guide member 330 and the buffer space 311 can be implemented in a variety of different structures by those skilled in the art, the specific structures of the buffer space 311 and the guide member 330 are not limited in this application. The guide member can also be an optical axis. In addition, a sliding layer is provided on the inner wall of the fixed frame to facilitate the sliding of the guide member.

[0058] The tarpaulin frame with anti-deformation function provided in the present application can, through the arrangement of the above-mentioned structure, enable the horizontal bar 100 and the upright stake 200 to move relative to each other when the tarpaulin frame is impacted by external force, and the external force is consumed in the buffer space 311, thereby greatly reducing the stress that may be generated between the two, so as to avoid adverse deformation of the tarpaulin frame as much as possible, and thus help to ensure the stability of the overall structure of the tarpaulin frame.

[0059] In a specific example, the fixing frame 310 and the vertical section 130 are integrally formed, and the mounting base 320 and the stake 200 are integrally formed. This integral molding method helps improve the connection strength between the fixing frame 310 and the horizontal bar 100, and between the mounting base 320 and the stake 200, making the relative movement between the horizontal bar 100 and the stake 200 more stable.

[0060] In some embodiments, the fixing frame 310 has a fixing hole (not shown), and one of the first contact surface 110 and the second contact surface 210 has an assembly hole (not shown); the mounting base 320 has a mounting hole (not shown), and the other of the first contact surface 110 and the second contact surface 210 has a connection hole (not shown). In addition, the guide assembly 300 also includes a fastener (not shown), which can pass through the fixing hole and mate with the assembly hole, and pass through the mounting hole and mate with the connection hole to respectively achieve a detachable connection between the fixing frame 310 and the horizontal bar 100, and between the mounting base 320 and the stake 200. Optionally, the fixing hole, assembly hole, mounting hole, and connection hole can all be threaded holes, and the fastener can be a screw, bolt, or stud that mates with the threaded hole. This application does not limit the specific structure of the above-mentioned parts.

[0061] In this embodiment, a detachable connection is achieved between the fixing frame 310, the mounting seat 320, the cross bar 100 and the stake 200 by setting the fixing holes, assembly holes, installation holes, connecting holes and fasteners. This detachable connection setting method facilitates the user to maintain the guide assembly 300 in the later stage, and also enables the tarpaulin rack to adapt to guide assemblies 300 of different specifications and sizes, which is beneficial to the user experience.

[0062] In another specific example, referring to Figure 5 and Figure 6 As shown, guide member 330 is a roller comprising a roller shaft 331 and a roller body 332. Both ends of roller shaft 331 are fixedly connected to the sidewalls of mounting groove 321. Roller body 332 is sleeved around roller shaft 331. The edge of roller body 332 has a pair of radially extending stoppers 333, with the distance between the stoppers 333 being no less than the width of fixed frame 310. The provision of stoppers 333 limits the axial displacement of guide member 330, preventing axial wobble of guide member 330 and mounting base 320 relative to fixed frame 310, thereby further improving the stability of guide assembly 300.

[0063] In some embodiments, continue to refer to Figure 5 and Figure 6As shown, there are two rollers, one on each side of the centerline of the stake 200. When multiple rollers are provided, the relative movement between the fixing frame 310 and the mounting base 320 can be smoother. Furthermore, the relative displacement distance between the fixing frame 310 and the mounting base 320 can be limited to a certain extent, thereby preventing the centerline of the crossbar 100 from deviating excessively from the centerline of the stake 200. This improves the overall stability and structural strength of the tarpaulin frame during deformation.

[0064] Furthermore, the ratio of the length of the fixing frame 310 to the width of the vertical section 130 is between 1.5 and 1. Although this application does not specify the dimensions of the components of the guide assembly 300, in order to simultaneously maintain the structural stability and deformation limit of the tarpaulin rack, the ratio of the dimensions of the fixing frame 310 to the vertical section 130 of the crossbar 100 is defined, ensuring that the buffer space 311 meets the deformation requirements and structural stability of the tarpaulin rack. The width of the vertical section 130 and the length of the fixing frame 310 both refer to the distance along the length of the truck compartment.

[0065] In addition, since the present application does not limit the number of horizontal bars 100 and upright stakes 200 in the tarpaulin frame, when the number of horizontal bars 100 and upright stakes 200 is different, the number of guide assemblies 300 can also be configured in various embodiments:

[0066] Implementation Method 1

[0067] There are two horizontal bars 100 and four upright stakes 200 , and the four upright stakes 200 correspond to two horizontal bars 100 , respectively. There are two guide assemblies 300 , and the two guide assemblies 300 are respectively arranged on both sides of any horizontal bar 100 .

[0068] Implementation Method 2

[0069] Reference Figure 1 As shown, there are two horizontal bars 100 and four upright stakes 200 , and the four upright stakes 200 correspond to the two horizontal bars 100 in pairs; there are four guide assemblies 300 , and the four guide assemblies 300 are respectively arranged on both sides of the two horizontal bars 100 .

[0070] Implementation Method 3

[0071] For some vehicles with longer carriages (such as 17.5m carriages, 13.6m carriages, 9.6m carriages, etc.), in addition to setting two cross bars 100 at the front and rear ends of the carriage, multiple cross bars 100 can be set at intervals between the front and rear cross bars 100 to further enhance the overall structural strength and stability of the tarpaulin rack and the truck tarpaulin system. For example, for a 17.6m carriage, the number of cross bars 100 in the tarpaulin rack can be five, of which two cross bars 100 are set at the front and rear ends of the carriage, respectively, and the other three cross bars 100 are evenly spaced between the front and rear cross bars 100. It should be noted that the bottoms of the three middle cross bars 100 can be provided with stakes 200, or stakes 200 may not be provided. Moreover, when the stakes 200 are provided at the bottom of the three horizontal bars 100, a guide assembly 300 may be provided between any horizontal bar 100 and the stake 200; of course, the guide assembly 200 may not be provided between the three middle horizontal bars 100 and the stake 200, and this application does not limit this.

[0072] It will be appreciated that the relative displacement limits between the horizontal bar 100 and the upright stakes 200 vary depending on the number of guide assemblies 300 provided in the tarpaulin frame. For example, in the first embodiment described above, the relative displacement limit between the horizontal bar 100 and the upright stakes 200 is determined by the distance between the buffer spaces 311 in the fixing frame 310. In the second embodiment described above, since there are two guide assemblies 300 on the same side of the tarpaulin frame, the relative displacement limit between the horizontal bar 100 and the upright stakes 200 is double that of the second embodiment.

[0073] Furthermore, in other embodiments, the guide assembly 300 may further include a stopper (not shown), wherein the stopper may be a stopper pin, a stopper post, a stopper plate, a stopper block, a stopper bolt, or the like disposed on the mounting base. The stopper can secure the relative position of the fixing frame 310 and the mounting base 320 in the guide assembly 300, thereby improving the structural stability of the guide assembly 300 and, to a certain extent, preventing the tarpaulin frame from shaking during the truck's travel due to the inability to secure the fixing frame 310 and the mounting base 320 relative to each other.

[0074] Furthermore, the guide assembly 300 may also include a buffer member (not shown in the figure) arranged in the buffer space 311, and the buffer member can contact the guide member 330 during the movement of the guide member 330 in the buffer space 311. By setting the buffer member, the movement process of the guide member 330 can be buffered, and the guide member 330 can be prevented from generating an overload impact on the fixed frame 310 as much as possible, thereby improving the stability of the guide assembly 300. The buffer member can be a buffer spring, a buffer gasket, an elastic plate, a buffer filler, etc., and the present application does not limit the specific type of the buffer member. In addition, the buffer member and the guide member 330 can be directly connected or not connected, and the present application does not limit the specific setting method of the buffer member.

[0075] In some embodiments, the stake 200 of the present application is a lifting column with a multi-stage telescopic structure. The telescopic lifting column allows the height of the stake 200 to be flexibly adjusted, thereby allowing the tarpaulin rack to adapt to truck compartments of different specifications and sizes, thereby expanding the applicability of the tarpaulin rack.

[0076] In addition, continue to refer to Figure 1 As shown, an embodiment of the present invention also provides a truck tarpaulin system, including a tarpaulin cover 400 and a tarpaulin frame as described above, the cross bar 100 is provided with a guide member 150, and the tarpaulin cover 400 is provided with a transmission member (not marked in the figure), and the transmission member and the guide member 150 cooperate to enable the tarpaulin cover 400 to move along the contour of the tarpaulin frame.

[0077] Among them, the guiding member 150 can be a chain, and the transmission member can be a sprocket, and the sliding connection between the tarpaulin cover 400 and the tarpaulin frame is achieved through the cooperation between the chain and the sprocket; or, the guiding member 150 can be a rack, and the transmission member can be a gear, and the sliding connection between the tarpaulin cover 400 and the tarpaulin frame is achieved through the cooperation between the gear and the rack.

[0078] It can be understood that the truck tarpaulin system provided in the present application may not be provided with a tarpaulin cover 400 in actual application, and the tarpaulin covering the outside of the tarpaulin frame can be raised and lowered only by the lifting function of the stakes 200 themselves; or, the truck tarpaulin system may further include a cloth rolling assembly (not shown in the figure) provided on the outside of the tarpaulin frame, the cloth rolling assembly including a cloth rolling rod connected to the edge of the tarpaulin and a driving member connected to the cloth rolling rod; wherein the cloth rolling rod can rotate as the driving member is driven, and can retract the tarpaulin to the outside of the cloth rolling rod, thereby realizing the deployment and retraction of the tarpaulin on the outside of the tarpaulin frame.

[0079] In addition, refer to Figure 7 and Figure 8As shown, an embodiment of the present application further provides a novel carriage, comprising a carriage body 500 and a truck tarpaulin system disposed on the carriage body 500. The tarpaulin system includes a tarpaulin frame and a tarpaulin cover 400 that slidably engages with the tarpaulin frame. The tarpaulin frame includes a horizontal bar 100, a stake 200 located below the horizontal bar 100, and a guide assembly 300 connected to the horizontal bar 100 and the stake 200, respectively. The provision of the tarpaulin frame can largely prevent the truck tarpaulin system from failing when the carriage body 500 deforms, thereby improving the overall stability and reliability of the carriage.

[0080] In this embodiment, the guide assembly 300 may further include a first guide group 340 disposed at the connection between the horizontal bar 100 and the upright stake 200. The first guide group 340 has a first motion path. In response to deformation of the tarpaulin frame, the first guide group 340 can move along the first motion path to achieve relative motion between the horizontal bar 100 and the upright stake 200. The direction of the first motion path can be the same as the width direction of the body 500 or the same as the length direction of the body 500. This application does not limit the direction of the first motion path.

[0081] Specifically, refer to Figure 8 As shown, the first guide group 340 may include a first fixed portion 341 provided on the horizontal bar 100 and a first sliding portion 342 slidably engaged with the first fixed portion 341 , and a first rotating portion 343 provided below the first sliding portion 342 . The first guide group 340 is rotatably connected to the pile 200 via the first rotating portion 343 .

[0082] Among them, the first fixed part 341 can be a fixed guide rail, a fixed guide block, a guide tube, etc., the first sliding part 342 can be a sliding seat, a guide groove, a guide wheel, a ball, a roller, etc. that cooperate with the fixed guide rail and the fixed guide block respectively, and the first rotating part 343 can be a universal ball, a hinged seat, etc. This application does not limit the specific structures of the first fixed part 341, the first sliding part 342 and the first rotating part 343.

[0083] It is understood that the first fixed portion 341 cooperates with the first sliding portion 342 to achieve relative motion therebetween, and the motion path formed by the first fixed portion 341 relative to the first sliding portion 342 forms a first motion path. The presence of the first motion wheel allows the tarpaulin rack to reduce horizontal stress that may occur at the connection between the horizontal bar 100 and the upright stake 200 after the horizontal bar 100 or the upright stake 200 receives deformation transmitted from the body 500. Furthermore, the provision of the first rotating portion 343 enables a certain degree of relative rotation between the horizontal bar 100 and the upright stake 200, which helps to reduce vertical or circumferential stress that may occur at the connection between the two.

[0084] Regarding the specific structure of the first guide group 340, in addition to the above structure, it can also be implemented according to the following contents, specifically:

[0085] Reference Figure 9 As shown, the first guide group 340 in the present invention may include a first fixing portion 341 and a first sliding portion 342 that slides with the first fixing portion 341. The first fixing portion 341 may be a fixing plate, and the first sliding portion 342 may be a slider.

[0086] In some embodiments, reference Figure 10 As shown, the guide assembly 300 may further include a second guide group 350, the horizontal bar 100, the first guide group 340, the second guide group 350 and the stake 200 are connected in sequence, and the second guide group 350 has a second motion path; the first motion path is parallel to the length direction or width direction of the tarpaulin frame, and the second motion path is perpendicular to the first motion path; in response to the deformation of the tarpaulin frame, the first guide group 340 can move along the first motion path and / or the second guide group 350 can move along the second motion path to achieve relative movement between the horizontal bar 100 and the stake 200.

[0087] It should be noted that the second guide group 350 is arranged perpendicular to the first guide group 340, so that the second motion path is perpendicular to the first motion path. In other words, when the first motion path is along the length of the tarpaulin frame, the second motion path is along the width of the tarpaulin frame; when the first motion path is along the width of the tarpaulin frame, the second motion path is along the length of the tarpaulin frame.

[0088] The arrangement of the first guide group 340 and the second guide group 350 can reduce the horizontal stress that may be generated by the tarpaulin frame to the greatest extent, thereby further improving and reducing the possible deformation of the tarpaulin frame, thereby improving the structural stability of the tarpaulin frame.

[0089] Specifically, in this embodiment, continue to refer to Figure 10 As shown, the second guide assembly 350 may include a second sliding portion 351 connected to the first rotating portion 343, and a second fixed portion 352 slidably engaged with the second sliding portion 351. The first fixed portion 341 is connected to the horizontal bar 100, and the second fixed portion 352 is connected to the stake 200. Both the second sliding portion 351 and the second fixed portion 352 may be sliders, rails, etc., which are not limited in this application.

[0090] In some embodiments, reference Figure 10As shown, the first guide group 340 may further include a first stop portion 344 arranged at the end of the first sliding portion 342, and the second guide group 350 may further include a second stop portion 353 arranged at the end of the second sliding portion 351, and the first stop portion 344 and the second stop portion 353 can respectively cooperate with the first fixed portion 341 and the second fixed portion 352 to stop.

[0091] The setting of the first stop portion 344 and the second stop portion 353 can limit the stroke of the first movement path and the second movement path, preventing the first fixed portion 341 and the second fixed portion 352 from slipping off the first sliding portion 342 and the second sliding portion 351 respectively, thereby ensuring the stability of the sliding process of the first guide group 340 and the second guide group 350.
