[0080] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0081] Refer to Figures 1 to 8 As shown, for the convenience of introduction, the upper, lower, left, right, front, and rear orientations are used in the corresponding drawings to facilitate the introduction of the relative positional relationship between the various parts in the present application, and it should not be construed as a limitation on the absolute position.

[0082] Moreover, in the present application, the first direction corresponds to the left - right direction, the second direction corresponds to the up - down direction, and the third direction corresponds to the front - rear direction; similarly, here the indication of the first direction as the left - right direction is only for the convenience of introducing the specific embodiments of the present application, and there is no absolute corresponding relationship between the first direction and the left - right direction. Similarly, there is no absolute corresponding relationship between the second direction and the up - down direction, and the third direction and the front - rear direction.

[0083] The first direction, the second direction, and the third direction of the present application are also only for expressing the relative positional relationship, and they only indicate the general orientation, rather than the absolute geometric relationship.

[0084] According to the first aspect of the present application, refer to Figures 1 to 8 , the present application provides a guiding and supporting device 100 for connecting to a member 200 to be guided and supported. By using the guiding and supporting device 100, the member 200 to be guided and supported can be guided to be flattened and stored.

[0085] The guiding and supporting device 100 includes a prime mover 110 and a guiding and supporting assembly 120.

[0086] Among them, the prime mover 110 is configured to be rotatable about the prime mover axis 11a, and the guiding and supporting assembly 120 is rotationally connected to the prime mover 110 about the prime mover axis 11a. The guiding and supporting assembly 120 is connected to the member 200 to be guided and supported, and the guiding and supporting assembly 120 can, under the action of the prime mover 110, at least guide the member 200 to be movable relative to the prime mover axis 11a to a storage state, a fully flattened state, or a partially flattened state.

[0087] When the to-be-guided member 200 is in a fully flattened state, the guiding and supporting assembly 120 is adapted to apply a supporting force to the to-be-guided member 200 so that the to-be-guided member 200 remains in the fully flattened state.

[0088] Through the above technical solution, the guiding and supporting assembly 120 can be used to guide the to-be-guided member 200 so that the to-be-guided member 200 can be smoothly received or flattened, avoiding the situation of out-of-synchronization or jamming of the to-be-guided member 200 during the receiving or flattening process. At the same time, receiving the guiding member 121 can effectively reduce the space occupied by the guiding member 121. When the to-be-guided member 200 is in a fully flattened state, the guiding and supporting assembly 120 is adapted to apply a supporting force to the to-be-guided member 200 so that the to-be-guided member 200 remains in the fully flattened state, ensuring the stable use of the to-be-guided member 200.

[0089] Moreover, after the to-be-guided member 200 is received, the to-be-guided member 200 can be made more compact, and can be received when not in use, saving space and providing greater convenience, flexibility and durability.

[0090] It should be noted that the partially flattened state means that part of the to-be-guided member is unfolded to meet part of the usage requirements.

[0091] The fully flattened state means that all of the to-be-guided member 200 is unfolded.

[0092] Taking the to-be-guided member 200 as a flexible screen as an example, see Figures 1 to 3 , the fully flattened state means that the display area of the to-be-guided member 200 (flexible display screen) is completely guided out of the receiving space 15a. At this time, the to-be-guided member 200 (flexible display screen) is in the fully flattened state.

[0093] The partially flattened state means that the display area of the to-be-guided member 200 (flexible display screen) is partially guided out of the receiving space 15a.

[0094] The received state means that the display area of the to-be-guided member 200 (flexible display screen) is completely received into the receiving space 15a.

[0095] The switching of the to-be-guided member 200 (flexible display screen) among the three states depends on the user's usage.

[0096] In some embodiments, the guiding and supporting assembly 120 can be rotatably connected to the prime mover 110 about the prime mover axis 11a.

[0097] During the rotation of the guiding and supporting assembly 120 about the prime mover axis 11a, the to-be-guided member 200 is guided to rotate about the prime mover axis 11a, thereby completing the flattening or receiving of the to-be-guided member 200.

[0098] Among them, when the guiding and supporting component 120 and the prime mover 110 are configured to form a rotational connection about the prime mover axis 11a, the guiding and supporting component 120 can be configured as a shaft. The specific structure will be described below and will not be elaborated here.

[0099] In some embodiments, the guiding and supporting component 120 can also be configured as a rack, and the prime mover 110 is in power coupling with the rack. When the prime mover 110 rotates about the prime mover axis, it drives the rack to move relative to the prime mover axis 11a, thereby completing the flattening or storage of the component to be guided 200.

[0100] Among them, when the guiding and supporting component 120 is configured as a rack, a plurality of racks will be stacked together, thereby storing the component to be guided 200. At this time, the portion of the component to be guided that fits between two adjacent racks can also be folded.

[0101] In some embodiments, referring to Figure 3 , the guiding and supporting component 120 includes a guiding portion 12a.

[0102] The guiding portion 12a forms or is connected to a part of the component to be guided 200 and is in power coupling with the prime mover 110.

[0103] Under the action of a rotational force on the prime mover 110, the prime mover 110 can rotate about the prime mover axis 11a to drive the guiding portion 12a to rotate about the prime mover axis 11a, so that the component to be guided 200 can rotate about the prime mover axis 11a to the storage state, the fully flattened state, or the partially flattened state.

[0104] By applying a rotational force that can rotate about the prime mover axis 11a from the prime mover 110 to the guiding portion 12a, under the action of the rotational force, the effect of storing and flattening the component to be guided 200 is achieved. This operation method is simple and can guide and support the component to be guided 200 without setting many other components.

[0105] In some embodiments, referring to Figure 3 and Figure 4 , the guiding and supporting component 120 further includes a guiding member 121.

[0106] The guiding member 121 is connected to the component to be guided 200, the guiding portion 12a is formed on the guiding member 121 as a part of the guiding member 121, and the prime mover 110 has an embedding portion 11b.

[0107] At least a part of the guiding portion 12a is adapted to be embedded in the embedding portion 11b, so that the prime mover 110 drives the guiding member 121 to rotate about the prime mover axis 11a.

[0108] Specifically, the number of guiding members 121 is set corresponding to the number of embedding portions 11b. When the member 200 to be guided and supported is in a fully flattened state, at least a part of the guiding portion 12a of one of the guiding members 121 can be embedded into the embedding portion 11b. When the member 200 to be guided and supported switches from the fully flattened state to the storage state, at least a part of the guiding portions 12a of the remaining guiding members 121 will gradually be embedded into the embedding portion 11b, completing the guided storage of the member 200 to be guided and supported.

[0109] When switching from the storage state to the fully flattened state or a partially flattened state, the guiding portion 12a of the guiding member 121 will gradually move out of the embedding portion 11b. When in the fully flattened state, at least one guiding portion 12a needs to remain embedded in the embedding portion 11b to enable smooth guiding of the guiding member 121 next time.

[0110] In some embodiments, referring to Figure 3 and Figure 4 , the embedding portion 11b is configured as an embedding groove provided along the outer peripheral surface of the driving member 110. When the guiding member 121 rotates around the driving axis 11a, at least a part of the guiding member 121 is adapted to rotate into the embedding groove, so that the member 200 to be guided and supported is wound around the driving member 110.

[0111] By configuring the embedding portion 11b as an embedding groove, it is convenient for the guiding portion 12a of the guiding member 121 to rotate into the embedding groove, and the structure is stable.

[0112] The inner wall surface of the embedding groove is arranged as a curved surface. Correspondingly, the guiding portion 12a can be smoothly rotated into or out of the embedding groove.

[0113] Specifically, the driving member 110 can be configured as a sprocket wheel.

[0114] It should be noted that when the member 200 to be guided and supported is wound around the driving member 110, after a part of the member 200 to be guided and supported is wound onto the driving member 110, the remaining part of the member 200 to be guided and supported will continue to be wound to form a winding layer.

[0115] In some embodiments, the guiding and supporting assembly 120 further includes a plurality of supporting members 122 formed or connected to the member 200 to be guided and supported.

[0116] Among them, the different supporting members 122 are arranged in sequence along a second direction that intersects obliquely with the first direction where the driving axis 11a is located, and form a rotational connection around the driving axis 11a. During the rotation of the driving member 110 to drive the guiding member 121 to rotate around the driving axis 11a, each supporting member 122 rotates around the driving axis 11a synchronously with the member 200 to be guided and supported.

[0117] When the object to be guided 200 is in a fully flattened state, all the support members 122 will also unfold in the second direction. After unfolding, the support members 122 will also provide rigid support to the object to be guided 200. In particular, for some flexible objects to be guided 200, it can also provide a supporting force.

[0118] In some embodiments, referring to Figure 5 and Figure 6 , in order to prevent the object to be guided 200 from moving excessively in the unfolding rotation direction during the unfolding process, the guiding device 100 further includes a limiting structure 130.

[0119] The limiting structure 130 is configured to at least limit the rotation of the support member 122 from a preset maximum unfolding position around the driving axis 11a in the unfolding rotation direction;

[0120] Among them, referring to Figure 8 , the preset maximum unfolding position is the position where the support member 122 is located when the object to be guided 200 is in a fully flattened state.

[0121] In some embodiments, the limiting structure 130 includes a limiting portion 13a and a limiting interface 13b. Among them, a limiting portion 13a and a limiting interface 13b are respectively arranged at opposite ends of the support member 122. At least a part of the limiting interface 13b of one of the adjacent two support members 122 is arranged around at least a part of the limiting portion 13a of the other of the adjacent two support members 122, thereby completing the setting of a limiting structure 130 between two different support members 122.

[0122] Among them, the limiting portion 13a rotates relative to the limiting interface 13b to at least a first limiting position so that the support member 122 is in the preset maximum unfolding position.

[0123] Of course, the limiting portion 13a can also rotate relative to the limiting interface 13b to a second limiting position so that the support member 122 is in the preset maximum storage position.

[0124] Among them, when the limiting portion 13a rotates relative to the limiting interface 13b to at least a first limiting position so that the support member 122 is in the preset maximum unfolding position, it can limit the rotation of the support member 122 from the maximum unfolding position around the driving axis 11a in the unfolding rotation direction, thereby realizing the support for the object to be guided 200 and also avoiding the situation that the object to be guided is over-unfolded and bent.

[0125] Referring to Figure 5 , in some embodiments, the limiting portion 13a can be configured as a limiting block with a notch, and the limiting interface 13b is configured as a groove structure with a convex block. The two surfaces of the notch are arranged in an inclined intersection, and the two surfaces of the convex block are arranged in an inclined intersection.

[0126] Around the driving axis 11a of the driving member 110, the two surfaces of the notch form a first angle, and the two surfaces of the protrusion form a second angle. The first angle is made smaller than the second angle so that at least a part of the limiting block is adapted to rotate within the groove structure.

[0127] It should be noted that the angle by which the limiting portion 13a can rotate relative to the limiting interface 13b is the difference between the first angle and the second angle.

[0128] Reference Figure 5 , the notch includes a first notch surface 131 and a second notch surface 133, and the groove structure includes a first inner wall surface 132 and a second inner wall surface 134.

[0129] After the limiting block is inserted into the limiting interface 13b, the first notch surface 131 corresponds to the first inner wall surface 132, and the second notch surface 133 corresponds to the second inner wall surface 134. And because the first angle is smaller than the second angle, after the limiting block is inserted into the limiting groove structure, the limiting block will not fill up the limiting groove structure, that is, it allows the limiting block to rotate relative to the limiting groove structure. After the limiting block and the limiting groove structure rotate, the first notch surface 131 can contact the first inner wall surface 132, or the second notch surface 133 can contact the second inner wall surface 134.

[0130] Among them, when the member 200 to be guided and supported switches from the fully flattened state or the partially flattened state to the storage state, when the first notch surface 131 contacts the first inner wall surface 132, the second notch surface 133 separates from the second inner wall surface 134, and one support member 122 stops rotating relative to the other support member 122. At this time, the member 200 to be guided and supported is completely stored, and at this time, the second notch surface 133 and the second inner wall surface 134 do not contact.

[0131] It should be noted that with reference to Figure 7 , when the first notch surface 131 contacts the first inner wall surface 132, the limiting portion 13a rotates relative to the limiting interface 13b to the first limiting position, and at this time, the support member 122 is located at the preset maximum storage position.

[0132] When the member 200 to be guided and supported switches from the storage state to the fully flattened state, during the process that the first notch surface 131 gradually moves away from the first inner wall surface 132 and the second notch surface 133 gradually approaches the second inner wall surface 134 until the second notch surface 133 contacts the second inner wall surface 134, at this time, the member 200 to be guided and supported is completely flattened, and one support member 122 will stop rotating relative to the other support member 122. At this time, all the support members 122 will no longer rotate around the driving axis 11a in the unfolding rotation direction, that is, the support members 122 will no longer rotate forward, realizing the one-way fixation of the member 200 to be guided and supported, and further realizing the operation of the large-size flexible member 200 to be guided and supported and a more stable motion state.

[0133] Among them, the reference Figure 8 , when the second notch surface 133 contacts the second inner wall surface 134, the limiting part 13a rotates relative to the limiting interface 13b to the second limiting position, and at this time, the support member 122 is located at the preset maximum unfolding position.

[0134] It should be noted that the limiting block rotates by a certain angle within the limiting groove structure, and the angle range is the difference between the two angles, that is, the difference between the first angle and the second angle.

[0135] Exemplarily, the connected support members 122 can be configured as a chain, then the support member 122 is a link of the chain, and the limiting structure 130 is arranged between different support members 122.

[0136] When the object to be guided and supported 200 switches between the storage state, the fully flattened state, and the partially flattened state, the chain is synchronously retracted or flattened, and two adjacent links rotate relative to each other.

[0137] Specifically, referring to Figure 2 , the number of chains can be set to four, and each chain is connected to the reinforcement member 123.

[0138] In some embodiments, in order to further improve the support strength for the object to be guided and supported 200 when the guiding and supporting member is in the fully flattened state, the guiding and supporting assembly 120 further includes a reinforcement member 123.

[0139] Connect the reinforcement member 123 between different support members 122 along the first direction and arrange them in sequence along the second direction.

[0140] Specifically, the second direction can be set perpendicular to the first direction. This arrangement is convenient for connecting the support members 122, facilitating the stable unfolding and storage of the object to be guided and supported 200, and can also support the object to be guided and supported 200.

[0141] In some embodiments, the support member 122 has a hole structure 140 arranged at a position different from the limiting structure 130. The hole structure 140 is defined as the first hole structure, and the first hole structure surrounds at least part of the outer periphery of the reinforcement member 123 so that the reinforcement member 123 is connected to the support member 122.

[0142] Referring to Figure 5 , each support member 122 is provided with the first hole structure, and the support member 122 is connected to the reinforcement member 123 by using the first hole structure to ensure the synchronous movement of the support member 122.

[0143] Similarly, the guiding member 121 can also be connected to the supporting member 122. The two cooperate to support and connect the guiding member 121 accordingly. The guiding member 121 has a second hole structure that is different in position from the limiting structure 130. The second hole structure surrounds at least part of the outer periphery of the guiding member 121 to connect the supporting member 122 to the guiding member 121 and ensure the synchronous movement of the guiding member 121.

[0144] In some embodiments, at least one of the guiding member 121 and the reinforcing member 123 is configured as a circular shaft.

[0145] Reference Figure 2 , both the guiding member 121 and the reinforcing member 123 are configured as circular shafts, and the outer diameters and lengths of the circular shafts are also set to be the same.

[0146] Setting the guiding member 121 and the reinforcing member 123 to be the same is convenient for molding and has a high degree of generality.

[0147] In some embodiments, the guiding and supporting device 100 further includes a driving member 170.

[0148] The driving member 170 has at least one power output shaft 171 parallel to the first direction, and the prime mover 110 is non-rotatably connected to the power output shaft 171 of the driving member 170.

[0149] A driving force is applied to the prime mover 110 by the power output shaft 171 of the driving member 170 so that the prime mover 110 can rotate about the prime mover axis 11a.

[0150] Specifically, the driving member 170 can be set as a rotating motor.

[0151] In some embodiments, reference Figure 4 , in order to be able to store the member to be guided and supported 200 for easy carrying, the guiding and supporting device 100 further includes a mounting member 150. The mounting member 150 is used to provide a storage space 15a and a guiding channel 15b communicating with the storage space 15a.

[0152] Among them, at least part of the prime mover 110 is located in the storage space 15a. The prime mover 110 is adapted to drive the guiding and supporting assembly 120 to rotate about the prime mover axis 11a to guide at least part of the member to be guided and supported 200 to be retracted into the storage space 15a along the guiding channel 15b or guide at least part of the member to be guided and supported 200 to be output from the storage space 15a along the guiding channel 15b.

[0153] Specifically, the mounting member 150 is a cylindrical housing 151, and the guiding channel 15b is a groove opened on the housing 151. The groove communicates with the storage space 15a inside the housing 151.

[0154] In some embodiments, reference Figures 1 to 4, in order to facilitate the smooth output of the to-be-guided member 200 from the storage space 15a along the guiding channel 15b after being wound into the storage space 15a, a fixing member 160 is provided at the distal end of the to-be-guided member 200. The width of the fixing member 160 is greater than the width of the guiding channel 15b. When the to-be-guided member 200 is in the storage state, the fixing member 160 is located outside the storage space 15a, which can make the end of the to-be-guided member 200 face the guiding channel 15b, thus ensuring that the to-be-guided member 200 can be output from the storage space 15a along the guiding channel 15b again.

[0155] Specifically, the fixing member 160 can be configured as a long strip column.

[0156] According to the second aspect of the present application, with reference to Figure 1 and Figure 2 , a display device 10 is provided, which includes a to-be-guided member 200 and a guiding and supporting device 100. The guiding and supporting device 100 is the guiding and supporting device 100 described above, and this guiding and supporting device 100 is adapted to guide the to-be-guided member 200 to rotate.

[0157] Since the display device 10 includes the above-described guiding and supporting device 100, it has all the beneficial effects described for the above guiding and supporting device 100, and the present application will not elaborate herein.

[0158] In some embodiments, the to-be-guided member 200 may include at least one of a flexible display screen and a curtain.

[0159] The display device 10 is convenient to carry during use, and when unfolded, it can achieve one-way fixation of the to-be-guided member 200.

[0160] Exemplarily, when the display area of the flexible display screen is completely guided out of the storage space 15a for user use, the flexible display screen of the display device is in a completely flattened state. The limiting structure 130 can be used to perform one-way fixation on the flexible display screen to ensure that the flexible display screen will not be over-unfolded.

[0161] According to the third aspect of the present application, with reference to Figure 9 , a vehicle 1 is further provided, which includes the display device 10, and the display device 10 is the display device 10 described above. The vehicle 1 has all the beneficial effects of the above display device 10, and the present application will not elaborate herein.

[0162] The vehicle 1 can be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and the present application does not make specific limitations thereto.
