[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] (Embodiment 1)

[0052] Figure 1 It is a schematic structural diagram of the cache system in the first implementation manner of the present application.

[0053] As Figure 1 shown, the cache system 1000 includes at least two cache devices 100 and a handling component 200. The handling component 200 is used to move the object 10 in at least one cache device 100 to at least one other cache device 100.

[0054] In this implementation manner, the object 10 is a tray for holding products. The object 10 is not limited thereto. For example, the flat cardboard in Embodiment 3.

[0055] In this embodiment, the buffer system 1000 includes two buffer devices 100 and a handling component 200. In the following text, without special instructions, the objects 10 in the right buffer device 100 are all filled with products, and the objects 10 in the left buffer device 100 are all empty. The right buffer device 100 is used to continuously supply the objects 10 to the loading station for a robot (not shown in the figure) on the production line to grab the products. The handling component 200 is used to move the object 10 to the left buffer device 100 after the product in the object 10 is emptied.

[0056] The buffer system 1000 is provided with areas A, B, C, and D. Figure 1 The two dashed arrows in the figure show the moving directions of the object 10. The object 10 is placed into the buffer system 1000 from area A, and after passing through areas B and C, it is taken out from area D.

[0057] In other embodiments, the number of the buffer devices 100 can be set as needed, and the uses of multiple buffer devices 100 can be reasonably allocated as needed.

[0058] Figure 2 is Figure 1 the right view of. As Figure 1 and Figure 2 shown, the buffer device 100 includes a frame 110, a mounting base 120, a first driving component 130, a supporting member 140, and a second driving component 150. The mounting base 120 is movably connected to the frame 110 in the vertical direction. The first driving component 130 is used to drive the mounting base 120 to lift and lower. The supporting member 140 is rotatably connected to the mounting base 120. The second driving component 150 is used to drive the supporting member 140 to rotate relative to the mounting base 120, so that at least part of the projection of the supporting member 140 and the object 10 to be lifted and lowered in the vertical direction intersects or has no intersection, so that the supporting member 140 can lift or avoid the object 10 during the lifting and lowering process following the mounting base 120. Specifically, when at least part of the projection of the supporting member 140 and the object 10 to be lifted and lowered in the vertical direction intersects (see Figure 1 , the first predetermined position), the supporting member 140 can lift the object 10 during the lifting and lowering process. When there is no intersection between the projection of the supporting member 140 and the object 10 to be lifted and lowered in the vertical direction (see Figure 1 , the second predetermined position), the supporting member 140 can avoid the object 10 during the lifting and lowering process following the mounting base 120.

[0059] In this embodiment, the buffer device 100 includes one frame 110, two mounting bases 120, one first driving component 130, two supporting members 140, and two second driving components 150.

[0060] Two supporting members 140 are spaced apart on the left and right sides of the frame 110 to lift the object 10 from both sides. In other embodiments, a larger number of supporting members 140 can also be provided. The larger number of supporting members 140 can be spaced around the object 10. Correspondingly, an equal number of mounting seats 120 and second driving components 150 need to be provided. Of course, if the bearing surface of the supporting member 140 is large enough, only one supporting member 140 can be provided. Correspondingly, only one mounting seat 120 and one second driving component 150 need to be provided.

[0061] The two mounting seats 120 correspond to the two supporting members 140 one by one. The first driving component 130 is used to drive the two mounting seats 120 to lift simultaneously to ensure the synchronous movement of the two mounting seats 120, and at the same time, the manufacturing cost can be reduced.

[0062] The two second driving components 150 correspond to the two supporting members 140 one by one. Each supporting member 140 is hinged to the corresponding mounting seat 120. Each second driving component 150 is used to drive the corresponding supporting member 140 to rotate relative to the mounting seat 120.

[0063] The working processes of the left and right buffer devices 100 are described below respectively. The left and right buffer devices 100 are provided with first, second, and third heights from top to bottom in sequence. Figure 1 The mounting seats 120 and supporting members 140 shown by the dotted lines in the figure are the mounting seats 120 and supporting members 140 located at the first height and the third height.

[0064] The working process of the buffer device 100 on the right side includes the following steps:

[0065] Step S101: The second driving component 150 drives the supporting member 140 to rotate relative to the mounting seat 120 until there is no intersection in the vertical projection with the object 10;

[0066] Step S102: The first driving component 130 drives the mounting seat 120 to descend to the third height;

[0067] Step S103: The second driving component 150 drives the supporting member 140 to rotate relative to the mounting seat 120 until there is at least partial intersection in the vertical projection with the object 10;

[0068] Step S104: The first driving component 130 drives the mounting seat 120 to rise to the second height. Among them, when the supporting member 140 rises following the mounting seat 120, it lifts multiple objects 10 stacked in area A to area B. When the mounting seat 120 is at the second height, the uppermost object 10 on the supporting member 140 is at the loading station;

[0069] Step S105: After the top object 10 is emptied, every time the handling component 200 removes one object 10, the first driving component 130 drives the mounting base 120 to rise by a predetermined distance, which is the distance between two stacked objects 10, until the mounting base 120 moves to the first height. During this period, a plurality of objects 10 are stacked in area A (for replenishment).

[0070] Repeat steps S101 to S105.

[0071] The working process of the buffer device 100 on the left side includes the following steps:

[0072] Step S201: The first driving component 130 drives the mounting base 120 to rise to the first height.

[0073] Step S202: The second driving component 150 drives the supporting member 140 to rotate relative to the mounting base 120 until it at least partially intersects with the object 10 in the vertical projection direction to receive the object 10 carried by the handling component 200.

[0074] Step S203: Every time one object 10 is received, the first driving component 130 drives the mounting base 120 to descend by a predetermined distance, which is the distance between two stacked objects 10, until the mounting base 120 moves to the second height. At this time, a plurality of objects 10 are stacked on the supporting member 140. During this period, a plurality of objects 10 in area D are taken away.

[0075] Step S204: The first driving component 130 drives the mounting base 120 to descend to the third height. During the process of the supporting member 140 following the mounting base 120 to descend, the plurality of objects 10 above it are placed in area D.

[0076] Step S205: The second driving component 150 drives the supporting member 140 to rotate relative to the mounting base 120 until there is no intersection with the plurality of objects 10 in the vertical projection direction.

[0077] Repeat steps S201 to S205.

[0078] In this embodiment, when the supporting member 140 in the buffer device 100 on the right side holds the object 10 in area B, objects 10 can be replenished in area A. After the objects 10 in area B are all handled, the supporting member 140 can avoid the objects 10 in area A, move to the lower part of the objects 10 in area A, lift the objects 10 in area A to area B, and continue feeding. The operation of replenishing objects 10 will not interrupt the feeding operation, realizing continuous feeding without interruption, reducing the manufacturing cost and the occupied space.

[0079] After the carrier 140 in the buffer device 100 on the left drops the object 10 into the D area, it can avoid the object 10 in the D area and return to the C area to continue receiving the object 10. When the carrier 140 receives the object 10 in the C area, it can pick up the object 10 in the D area to make room for the next batch of objects 10. The action of picking up the object 10 will not interrupt the continuous action of receiving the object 10. By setting the buffer device 100 on the left, the object 10 in the buffer device 100 on the right can be stored.

[0080] The carrier 140 is hinged to the mounting seat 120 through a hinge shaft 123 (see below), and the hinge shaft 123 is perpendicular to the up-down direction. The carrier 140 can rotate without occupying the space outside in the left-right direction during the rotation process.

[0081] In addition, in order to make the rotation of the carrier 140 relative to the mounting seat 120 more controllable, the second driving component 150 is used to drive the carrier 140 to rotate relative to the mounting seat 120 to a first predetermined position or a second predetermined position. When the carrier 140 is in the first predetermined position, it at least partially intersects with the object 10 to be lifted and lowered in the up-down direction projection. When the carrier 140 is in the second predetermined position, there is no intersection with the object 10 to be lifted and lowered in the up-down direction projection. Preferably, when the carrier 140 is in the first predetermined position, the surface for carrying the object 10 is perpendicular to the up-down direction, and the object 10 can be lifted more stably. When the carrier 140 is in the second predetermined position, the surface for carrying the object 10 is parallel to the up-down direction. In this way, the projection area of the carrier 140 in the up-down direction is smaller at the second predetermined position. Since a certain space needs to be reserved between the frame 110 and the object 10 for the carrier 140 to move in the up-down direction at the second predetermined position, if the projection area is smaller, the space to be reserved can be narrower in the left-right direction, thereby reducing the space occupied by the buffer device 100.

[0082] The following will introduce each component of the buffer device 100 separately.

[0083] The frame 110 is the structural main body of the buffer device 100, which can be fixed to the ground and is used to support other components. The frame 110 includes a top plate 111, a bottom plate 112, and a plurality of guide columns 113. The plurality of guide columns 113 are supported between the top plate 111 and the bottom plate 112 to jointly form a frame structure. The structure of the frame 110 is not limited to this, and other reasonable structures can also be adopted.

[0084] Figure 4 is Figure 1 a partial top view of, and the top plate of the frame is omitted. As Figure 1 、 Figure 2 and Figure 4As shown, the mounting base 120 includes a mounting body 121, a bracket 122, a hinge shaft 123, a connecting member 124, and a guide sleeve 125. The mounting body 121 is slidably engaged with the guide post 113 in the frame 110 through the guide sleeve 125. The mounting body 121 and the guide sleeve 125 can be a split structure or an integral structure. The bracket 122 is fixed to the mounting body 121. The hinge shaft 123 is rotatably disposed on the bracket 122 about its own axis and is spaced from the mounting body 121 in the up and down directions. The space formed by the hinge shaft 123 and the mounting body 121 in the up and down directions can be used to accommodate a part of the second driving assembly 150. The supporting member 140 is generally in the shape of a flat plate, ( Figure 1 in) and its upward-facing surface is used to carry the object 10. The supporting member 140 is spaced from the hinge shaft 123 and is fixedly connected to the hinge shaft 123 through the connecting member 124. The connecting member 124 and the supporting member 140 can be a split structure or an integral structure.

[0085] In other embodiments, the hinge shaft 123 can also be fixed to the bracket 122, the connecting member 124 is rotatably sleeved on the hinge shaft 123, and the supporting member 140 is fixedly connected to the connecting member 124. Through this method, the hinge structure can also be achieved.

[0086] Figure 3 is Figure 1 the bottom view of. As Figure 1 、 Figure 2 and Figure 3 shown, the first driving assembly 130 includes two lead screws 131, two transmission wheels 132, a motor 133, a driving wheel 134, and a conveyor belt 135. The two lead screws 131 correspond to the two mounting bases 120 one by one. Each lead screw 131 is in screw drive engagement with its corresponding mounting base 120 and is rotatably disposed on the frame 110 about its own axis. The two transmission wheels 132 correspond to the two lead screws 131 one by one. Each transmission wheel 132 is coaxially fixed to its corresponding lead screw 131. The motor 133 is fixed to the bottom plate 112 of the frame 110. The driving wheel 134 is coaxially fixed to the output shaft of the motor 133. The conveyor belt 135 is wound around the two transmission wheels 132 and the driving wheel 134 in sequence. Through this specific method, the motor 133 can drive the two lead screws 131 to rotate synchronously, so as to drive the two mounting bases 120 to lift and lower synchronously. At the same time, due to the use of screw drive, the accidental fall of the mounting base 120 can be avoided.

[0087] As Figure 2As shown in the figure, the second driving component 150 includes a first transmission part 151, a movable part 152, a second transmission part 153 and a power part 154. The first transmission part 151 is arranged on the supporting part 140. The first transmission part 151 and the supporting part 140 can be of a split structure or an integral structure. The movable part 152 is axially movably connected to the mounting seat 120 on the hinge shaft 123. Specifically, the movable part 152 can be movably connected to the mounting seat 120 through a slide rail and slider structure. The second transmission part 153 is arranged on the movable part 152. The power part 154 is used to drive the movable part 152 to move. The power part 154 can be a cylinder, the cylinder body of which is fixedly arranged on the mounting main body 121, and the piston rod of which is fixedly connected to the movable part 152. Wherein, the first transmission part 151 and / or the second transmission part 153 has an inclined surface, the inclined surface is inclined to the axial direction of the hinge shaft 123 of the supporting part 140 and the mounting seat 120, and the inclined surface makes the first transmission part 151 and the second transmission part 153 abut against each other during the movement of the movable part 152, and gives a torque for the supporting part 140 to rotate.

[0088] Through the transmission cooperation of the first transmission part 151 and the second transmission part 153, the linear motion of the movable part 152 is converted into the rotation of the supporting part 140. There are many means to drive the linear motion of the movable part 152, and the manufacturing cost is low. In other embodiments, the supporting part 140 can also be driven to rotate by a motor. However, the requirements for the motor are relatively high, which will increase the manufacturing cost.

[0089] Furthermore, the first transmission part 151 protrudes from the side of the supporting member 140 facing the hinge shaft 123. The movable member 152 is non-rotatably sleeved on the hinge shaft 123, so that the movable member 152 is received between the gap of the supporting member 140 and the mounting body 121, reducing the space occupied by the second driving assembly 150. In addition, at least the surface of the movable member 152 facing the supporting member 140 is a second cylindrical surface. This second cylindrical surface can be coaxial with the hinge shaft 123. The second transmission part 153 is arranged on the second cylindrical surface. The second transmission part 153 is a first groove 153 opened on the second cylindrical surface. On the premise of meeting the depth of the first groove 153, the radial dimension of the second cylindrical surface on the radial direction of the hinge shaft 123 is the smallest. Since the supporting member 140 rotates around the movable member 152 at the same time, this second cylindrical surface can make the structure of the supporting member 140 and the movable member 152 compact. The first transmission part 151 is slidably / rollably inserted into the first groove 153, which can reduce the space occupied by the transmission and cooperation structure of the supporting member 140 and the movable member 152. The first transmission part 151 can be a part of the supporting member 140. At this time, the first transmission part 151 is slidably inserted into the first groove 153. The first transmission part 151 can be a roller (see below), and the first transmission part 151 is rollably inserted into the first groove 153. The extending direction of the first groove 153 is inclined to the hinge shaft 123, so that the two opposite side surfaces of the first groove 153 form inclined surfaces. Specifically, the first groove 153 extends along the circumferential direction and the axial direction of the hinge shaft 123 at the same time. When the power member 154 drives the movable member 152 to move, the side surface of the first groove 153 exerts a force on the first transmission part 151, forcing the first transmission part 151 to rotate around the hinge shaft 123, thereby driving the supporting member 140 to rotate.

[0090] Furthermore, at least one end of the first groove 153 extends along the axial direction of the hinge shaft 123 to form a second groove 155. The widths of the first groove 153 and the second groove 155 can be the same, so that the first transmission part 151 can smoothly pass through the connection part of the two. Among them, when the first transmission part 151 is clamped in the second groove 155, the supporting member 140 is held in a state where it at least partially intersects with the object 10 to be lifted in the vertical projection.

[0091] If the second groove 155 is not provided, when the supporting member 140 is in a state where it at least partially intersects with the object 10 to be lifted in the vertical projection, the force received due to lifting the object 10 will be transmitted to the power member 154 through the side surface of the first groove 153, causing the power member 154 to receive the force in the axial direction of the hinge shaft 123, which will reduce the service life of the power member 154. After the second groove 155 is provided, since the side surface of the second groove 155 is parallel to the hinge shaft 123, the force exerted by the first transmission part 151 on the side surface of the second groove 155 will only be perpendicular to the axial direction of the hinge shaft 123, and this force will be transmitted to the mounting body 121. Therefore, damage to the power member 154 can be avoided.

[0092] In addition, setting the second groove 155 also makes it easier to control the carrier 140 to accurately rotate to the first predetermined position or the second predetermined position.

[0093] To reduce the resistance of the transmission cooperation between the carrier 140 and the movable member 154, the first transmission portion 151 may be a roller 151. The axis of the roller 151 is perpendicular to the carrier 140. The roller 151 rolls and abuts against the above-mentioned inclined surface. In this embodiment, the roller 151 is inserted into the first groove 153 or the second groove 155 and rolls and abuts against the side surface of the first groove 153 or the second groove 155.

[0094] To facilitate storing the object 10 in area A and taking the object 10 in area D, the buffer device 100 is further provided with a cartridge 160. The cartridge 160 is movably connected to the frame 110 and is used to carry the object 10. Figure 1 For the sake of simplicity of the drawings, the structure of the cartridge 160 is simplified.

[0095] Figure 5 FIG. is a schematic structural view of the connection between the cartridge and the frame in the first embodiment of the buffer system of the present application, only showing a part of the frame. Figure 6 is Figure 5 the top view of. As Figure 5 and Figure 6 shown, the cartridge 160 is movably connected to the frame 110 through a slide rail 170. The cartridge 160 can be pulled out from the main body structure of the buffer device 100, so as to facilitate taking parts from the cartridge 160 or storing parts in the cartridge 160.

[0096] The specific structure of the cartridge 160 includes a substrate 161, a first limiting rod 162, a second limiting rod 163, and a third limiting rod 164. The substrate 161 is movably connected to the frame 110 through a slide rail 170. The first limiting rod 162, the second limiting rod 163, and the third limiting rod 164 are fixed on the top surface of the substrate 161 and extend in the up and down directions, and together with the substrate 161 form a receiving space for storing the object 10. Due to the limitation of the first limiting rod 162, the second limiting rod 163, and the third limiting rod 164, the placement position of the object 10 is more accurate. When the buffer device 100 is applied to loading, the carrier 14 can accurately lift the object 10 to the loading station.

[0097] In addition, to further facilitate taking and placing the object 10 in the cartridge 160, the heights of the first limiting rod 162, the second limiting rod 163, and the third limiting rod 164 are not the same. In this embodiment, the first limiting rod 162 and the second limiting rod 163 are relatively short, and the object 10 can be taken and placed from this side.

[0098] To limit the material box 160 and prevent it from accidentally sliding out of the main structure of the buffer device 100 during operation, the buffer device 100 is also provided with a limiting cylinder 180. The cylinder body of the limiting cylinder 180 is fixed to the frame 110, and its piston rod is used to limit the material box 160 on the guiding path of the slide rail 170. When working normally, the piston rod extends to resist the material box 160 and prevent the material box 160 from moving. When picking or storing parts is required, the piston rod retracts and the material box 160 can move.

[0099] The buffer device 100 may also be provided with a sensor (not shown in the figure). The sensor is arranged at a third predetermined position for detecting whether there is an object 10 at the third predetermined position. For example, a sensor is arranged at the bottom (area A or area D) of the buffer device 100. When the buffer device 100 is applied to loading, if the sensor detects that there is no object 10, the operator can be reminded by a warning light to replenish the object 10 into the buffer device 100. When the buffer device 100 is applied to recycling the object 10, if the sensor detects the object 10, the operator can be reminded by a warning light to take out the object 10 from the buffer device 100.

[0100] The specific structure of the handling component 200 will be introduced below.

[0101] As Figure 1 and Figure 2 shown, the handling component 200 includes a transmission line 210, a moving seat 220, a first driver (not shown in the figure), a mounting bracket 230, a vacuum chuck 240, and a second driver 250. The transmission line 210 is arranged at the top of the left and right buffer devices 100. The moving seat 220 is movably arranged on the transmission line 210 and can move along the transmission line 210. The first driver is used to drive the moving seat 220 to move. The mounting bracket 230 is movably connected to the moving seat 220 in the up and down direction. The vacuum chuck 240 is arranged at the bottom end of the mounting member 230 and is used to communicate with a negative pressure source. The second driver 250 is used to drive the mounting bracket 230 to move. The transmission line 210, the moving seat 220, and the first driver can be combined to form a linear motor. The second driver 250 can be a cylinder. The number of vacuum chucks 240 can be set according to needs.

[0102] During operation, the first driver drives the moving seat 220 to move above the right buffer device 100. The second driver 250 drives the mounting bracket 230 to descend. After the vacuum chuck 240 adsorbs the object 10 in the right buffer device 100, the second driver 250 drives the mounting bracket 230 to rise. The first driver drives the moving seat 220 to move above the left buffer device 100. The second driver 250 drives the mounting bracket 230 to descend, and controls the vacuum chuck 240 to drop the object 10 into the left buffer device 100. The second driver 250 drives the mounting bracket 230 to rise. Thus, a handling operation is completed.

[0112] The structure of the first driving component 330 is simple, and further reduces the space occupied by the cache device 300.

[0113] For other parts of this embodiment, please refer to Embodiment 1, which will not be elaborated here.

[0114] (Embodiment 3)

[0115] Compared with Embodiment 1, this embodiment provides another hinged structure between the supporting member and the mounting base.

[0116] Figure 9 It is a schematic structural diagram of Embodiment 3 of the cache device of the present application. Figure 10 It is Figure 9 the right view of Figure 11 It isFigure 9 Top view, with the top plate in the frame omitted.

[0117] As Figures 9 to 11 shown, the buffer device 500 includes a frame 510, a mounting base 520, a first driving component 530, a supporting member 540, and a second driving component 550.

[0118] For the specific structure of the frame 510, reference can be made to Embodiment 1.

[0119] The mounting base 520 is generally plate-shaped and is movably connected to the frame 510 in the vertical direction.

[0120] The first driving component 530 is used to drive the mounting base 520 to move up and down. For the specific structure of the first driving component 530, reference can be made to Embodiment 1.

[0121] The supporting member 540 is generally plate-shaped and is hinged to the mounting base 520, and the hinge axis is parallel to the vertical direction.

[0122] The second driving component 550 can be a motor and is used to drive the supporting member 540 to rotate relative to the mounting base 520 to a first predetermined position or a second predetermined position. When the supporting member 540 is in the first predetermined position, it at least partially intersects with the object 10 to be lifted in the vertical direction projection. When the supporting member 540 is in the second predetermined position, there is no intersection with the object 10 to be lifted in the vertical direction projection.

[0123] In this embodiment, the object 10 is a flat cardboard.

[0124] For other parts of this embodiment, please refer to Embodiment 1 and will not be elaborated here.

[0125] (Embodiment 4)

[0126] Compared with Embodiment 1, this embodiment provides another structure of the second driving component.

[0127] Figure 12 is a schematic structural diagram of the second driving component in Embodiment 4 of the buffer device of the present application. Figure 13 is a cross-sectional view of a partial structure of the movable part in Embodiment 4 of the buffer device of the present application.

[0128] As Figure 12 and Figure 13 shown, the second driving component 150 includes a roller 151, a movable part 152, and a power part 154.

[0129] The movable member 152 is sleeved on the hinge shaft 123 and is axially movably connected to the mounting body 121 on the hinge shaft 123. The surface of the movable member 152 facing the hinge shaft 123 is a first cylindrical surface. A first groove 153 is formed on the first cylindrical surface, and the extending direction of the first groove 153 is inclined to the hinge shaft 123. Specifically, the first groove 153 extends along the circumferential and axial directions of the hinge shaft 123 simultaneously and is generally spiral.

[0130] The roller 151 is rotatably arranged on the hinge shaft 123 around its axis and is rollingly inserted into the first groove 153.

[0131] The power member 154 is used to drive the movable member 152 to move.

[0132] The supporting member 140 is spaced from and connected to the hinge shaft 123.

[0133] When the power member 154 drives the movable member 152 to move, the side surface of the first groove 153 abuts against the roller 151 and applies a force to the roller 151, and this force drives the supporting member 140 to rotate around the hinge shaft 123.

[0134] In this embodiment, using the roller 151 can reduce the resistance of the transmission fit. In other embodiments, a part of the hinge shaft 123 can also protrude, and this part is slidably inserted into the first groove 153, and this protruding part replaces the roller 151. Although the resistance is increased to some extent, the basic functions can still be satisfied.

[0135] In other embodiments, the roller 151 can also be arranged on the first cylindrical surface, while the first groove 153 is formed on the surface of the hinge shaft 123.

[0136] In this embodiment, the shape of the first cylindrical surface is beneficial to reducing the space occupied by the second driving assembly 150. However, the shape of the first cylindrical surface is not necessary.

[0137] Furthermore, one end of the first groove 153 extends axially along the hinge shaft 123 to form a second groove 155. The widths of the first groove 153 and the second groove 155 can be the same so that the roller 151 can smoothly pass through the connection part of the two. Wherein, when the roller 151 is clamped in the second groove 155, the supporting member 140 is held in a state where it at least partially intersects with the object 10 to be lifted in the up-and-down direction projection.

[0138] By providing the second groove 155, damage to the power member 154 can be avoided. It has been explained in detail in Embodiment 1 and will not be elaborated here.

[0139] Furthermore, both ends of the first groove 153 extend along the axial direction of the hinge shaft 123 to form two second grooves 155. When the rollers 151 are respectively clamped in the two second grooves 155 located at both ends of the first groove 153, the support member 140 is respectively located at a first predetermined position and a second predetermined position. In this way, it is easier to control the support member 140 to accurately rotate to the first predetermined position or the second predetermined position.

[0140] For other parts of this embodiment, please refer to Embodiment 1, which will not be elaborated here.

[0141] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
