Please refer to FIGS. 5 to 7 together. When the second support member 13 is located at the first position and the guide member 30 slides in the first direction away from the first support member 11 (that is, moves toward the third position), The guide member 30 drives the second support member 13 to move in a direction away from the first support member 11. When the second support member 13 moves to the second position, under the action of the guide member 30, the locking mechanism 50 moves the second support member 13 to the second position. A support member 11 is locked with the second support member 13 to prevent the first support member 11 and the second support member 13 from moving relative to each other; when the guide member 30 continues to move in the direction away from the first support member 11 from the second position ( That is, when it continues to move toward the third position), under the action of the guide member 30, the locking mechanism 50 releases the lock between the first support member 11 and the second support member 13, so that the guide member 30 can drive The second support member 13 continues to move in the direction away from the first support member 11. Similarly, when the second support member 13 moves to the third position, under the action of the guide member 30, the locking mechanism 50 again moves the second support member 13 to the third position. A supporting member 11 is locked with the second supporting member 13 to prevent the first supporting member 11 and the second supporting member 13 from moving relative to each other. When the second support member 13 is in the first position, the cooperation diagram between the guide member 30 and the locking mechanism 50 is as shown in FIG. 5 . When the second support member 13 is in the second position, the cooperation diagram between the guide member 30 and the locking mechanism 50 is as shown in FIG. 6 . When the second support member 13 is in the third position, the cooperation diagram between the guide member 30 and the locking mechanism 50 is as shown in FIG. 7 .

On the contrary, when the second support member 13 is located at the third position and the third position moves toward the first position, under the action of the guide member 30 , the locking mechanism 50 releases the connection between the first support member 11 and the second support member 13 . so that the guide member 30 can drive the second support member 13 to move closer to the first support member 11; when the second support member 13 moves to the second position, under the action of the guide member 30, the lock The closing mechanism 50 locks the first support member 11 and the second support member 13 to prevent the first support member 11 and the second support member 13 from moving relative to each other; when the guide member 30 continues to approach the first support member from the second position, When moving in the direction of 11 (that is, the direction approaching the first position), under the action of the guide member 30, the locking mechanism 50 releases the lock between the first support member 11 and the second support member 13, so that the guide member 30 can drive the second support member 13 to continue to move closer to the first support member 11 .

Optionally, when the second support member 13 is located at the first position, the second position and the third position, the support assembly 10 has different bearing areas, so that the pull-out device 100 has different bearing areas, when applied to electronic equipment. , which can enable the flexible display screen of electronic equipment to switch between different display areas. In other words, when the second support member 13 is located at the first position, the second position and the third position respectively, the bearing area of the pulling device 100 is different.

Specifically, when the second support member 13 is located at the first position, the pull-out device 100 has a first bearing area. When the second support member 13 is at the second position, the draw-out device 100 has a second bearing area. The second support member 13 When located in the third position, the pulling device 100 has a third bearing area, and the first bearing area < the second bearing area < the third bearing area.

The pulling device 100 in the embodiment of the present application includes a first support member 11, a second support member 13 and a guide member 30. The second support member 13 can be in a first position relative to the first support member 11 under the action of the guide member 30. The second position and the third position, so that when the second support member 13 is in different positions, the first support member 11 and the second support member 13 can cooperate to form different bearing areas. When the pull-out device 100 is applied to electronic equipment, the support When a flexible display screen is provided on the component 10, the display area of the flexible display screen of the electronic device can be adjusted by adjusting the position of the second support member 13 relative to the first support member 11 to meet the different display area sizes under different display situations. need. In addition, the pull-out device 100 also includes a locking mechanism 50, which is used to lock the first support member 11 and the second support member 13 when the second support member 13 is in the second position or the third position, It can not only prevent the second support member 13 from sliding or shaking relative to the first support member 11 and affecting the display effect of the electronic device, but also can prevent the second support member 13 from sliding or shaking relative to the first support member 11 when the pull-out device 100 falls or the support assembly 10 is hit by an external force. The external force is consumed between the closing mechanism 50 to prevent the external force from being transmitted to the guide 30, the flexible display screen or other components that drive the movement of the guide 30, thus affecting the stability and reliability of the display area adjustment of the electronic device. Furthermore, through the cooperation of the guide member 30 and the locking mechanism 50, multi-level self-locking and self-unlocking of the first support member 11 and the second support member 13 can be realized, without the need for additional locking and unlocking control mechanisms, and more No manual operation required.

In some embodiments, when the second support member 13 is in the first position, the locking mechanism 50 cooperates with the guide member 30 to lock the first support member 11 and the second support member 13 . In other words, when the second support member 13 is in any one of the first position, the second position and the third position, the locking mechanism 50 cooperates with the guide member 30 to connect the first support member 11 and the third position. The two supporting parts 13 are locked. In other embodiments, when the second support member 13 is in the first position, the first support member 11 and the second support member 13 may not be locked, that is, in an unlocked state (as shown in FIG. 5 ).

Referring to Figure 4, in some embodiments, the number of second positions is one. At this time, when a flexible display screen is installed on the support assembly 10, by adjusting the relative position of the second support member 13 and the first support member 11, the exposed area of the flexible display screen can be adjusted, so that the flexible display screen has features corresponding to Three display areas for the first position, the second position and the third position.

In other embodiments, the number of the second positions is multiple (not shown). When the number of the second positions is multiple, a plurality of the second positions are spaced apart from the first position. position and the third position. At this time, when a flexible display screen is installed on the support assembly 10, by adjusting the relative position of the second support member 13 and the first support member 11, the exposed area of the flexible display screen can be adjusted, so that the flexible display screen has more than four types of functions. display area, you can have more display areas to choose from. Compared with electronic devices that can only change the size of a flexible display screen between two or three sizes, it can meet the needs of more users and is suitable for more application scenarios. For example, when the pulling device 100 is applied to a mobile phone, since different users have different hand sizes, the carrying area of the pulling device 100 and the exposed area of the flexible display screen can be adjusted according to the size of the user's hand. , making it easier for the user to hold. When the user places the mobile phone to watch videos, images, etc., the flexible display screen can be adjusted to the maximum for better visual effects. The term "plurality" in this application means more than or equal to two.

Optionally, the number of second positions may be, but is not limited to, 1, 2, 3, 4, 5, 6, etc. The number of second positions can be determined based on the number of gears that can realize the self-locking function when the pulling device 100 implements multi-level self-locking.

Please refer to Figure 8 together. In some embodiments, the second support member 13 has a limiting groove 131, a first resisting surface 133 and a second resisting surface 135 forming the limiting groove 131. The first resisting surface 133 and the second resisting surface 135 are disposed oppositely, and the guide member 30 is partially slidably disposed in the limiting groove 131 . When the guide member 30 moves in a direction away from the first support member 11 , the guide member 30 moves in a direction close to the first resisting surface 133 until the guide member 30 resists the first resisting surface 133 . When holding the surface 133 , the guide member 30 drives the second support member 13 to move in a direction away from the first support member 11 ; when the guide member 30 moves in a direction close to the first support member 11 When the guide member 30 moves toward the second resisting surface 135 , until the guide member 30 resists the second resisting surface 135 , the guide member 30 drives the second supporting member 13 toward the second resisting surface 135 . Move closer to the first support member 11 . Through the action of the first resisting surface 133 and the second resisting surface 135, the relative sliding between the guide member 30 and the second supporting member 13 can be limited between the first resisting surface 133 and the second resisting surface 135. between.

Please refer to FIGS. 4 to 9 together. In some embodiments, the second support member 13 includes a first support body 132 , a second support body 134 and an adjustment member 136 . The first support body 132 is connected to the second support body 134 . The first support body 132 is slidingly connected to the first support member 11 . The second support body 134 faces the first support member 11 and protrudes from the first support body. 132. The second support body 134 has a connected slot 137 and an adjustment slot 138. The slot 137 is located on the surface connecting the second support body 134 and the first support body 132, and is used for passing the guide 30. The adjustment groove 138 penetrates the surface of the second support body 134 facing away from the first support member 11 and is used for disposing the adjustment member 136 and part of the guide member 30 . The adjusting member 136 is fixed on the side of the second supporting body 134 away from the first supporting member 11 and is located in the adjusting groove 138 . The adjusting member 136 and the second supporting body 134 form the limit. position slot 131 , the surface of the adjusting member 136 facing the limiting slot 131 is the second resisting surface 135 , and the surface of the second support body 134 facing the adjusting member 136 is the first resisting surface 133 . The guide 30 can be slidably inserted into the slot 137 , and after passing through the slot 137 , part of the guide 30 is slidably disposed in the limiting slot 131 .

In some embodiments, the distance L between the first resisting surface 133 and the second resisting surface 135 is between 2 mm and 5 mm. Specifically, the distance L between the first resisting surface 133 and the second resisting surface 135 is between 2 mm and 5 mm. The distance L between them can be, but is not limited to, 2mm, 2.5mm, 2.8mm, 3mm, 3.1mm, 3.3mm, 3.5mm, 3.8mm, 4.0mm, 4.3mm, 4.5mm, 4.8mm, 5.0mm. The distance between the first resisting surface 133 and the second resisting surface 135 cannot be too small. If the distance between the first resisting surface 133 and the second resisting surface 135 is too small, when the guide member 30 leaves the first In the second position or the third position, the locking mechanism 50 may not be unlocked, and it is difficult for the second support member 13 to move relative to the first support member 11, and the load-bearing area of the support assembly 10 cannot be changed, thereby changing the load-bearing capacity of the pull-out device 100. Therefore, when the pull-out device 100 is applied to an electronic device, it can change the display area of the flexible display screen of the electronic device. If the distance between the first resisting surface 133 and the second resisting surface 135 is too large, when the pulling device 100 is in the closed state, a larger sliding space of the guide 30 needs to be reserved, which increases the difficulty of pulling out. The volume of the pulling device 100 in the closed state is not conducive to miniaturization of the pulling device 100 .

Through the cooperation of the first rail member 71 and the second rail member 73, the second support member 13 can slide in the first direction more smoothly when moving relative to the first support member 11, thereby preventing the second support member 13 from colliding with the first support member 11. The relative deflection of the first support member 11 affects the stability and appearance of the pulling device 100 .

In some embodiments, the first track member 71 is a slide rail, and the second track member 73 is a chute, as shown in Figure 10 . The slide rail can be directly formed on the surface of the first support member 11 facing the second support member 13; in other words, the slide rail and the first support member 11 have an integral structure; or the slide rail and the first support member 11 have a separate structure. , the slide rail and the first support member 11 are fixed through fasteners such as bolts and nuts. The chute can be formed on the second support member 13; or the chute can be formed on the track member, and the track member is fixed to the second support member 13 through fasteners such as bolts and nuts. The sliding cooperation between the chute and the slide rail allows the second support member 13 to slide in the first direction more smoothly when moving relative to the first support member 11, thereby preventing the second support member 13 from colliding with the first support member 11. The relative offset affects the stability and appearance of the pulling device 100 . In addition, the structure is simple, which is beneficial to making the pulling device 100 thin and light.

In other embodiments, the first track member 71 is a slide groove, and the second track member 73 is a slide rail. The slide rail can be directly formed on the surface of the second support member 13 facing the first support member 11; in other words, the slide rail and the second support member 13 have an integrated structure; or the slide rail and the second support member 13 have a separate structure. , the slide rail and the second support member 13 are fixed by fasteners such as bolts and nuts. The chute can be formed on the first support member 11; or the chute can be formed on the track member, and the track member is fixed to the first support member 11 through fasteners such as bolts and nuts. The sliding cooperation between the chute and the slide rail allows the second support member 13 to slide in the first direction more smoothly when moving relative to the first support member 11, thereby preventing the second support member 13 from colliding with the first support member 11.

Referring to FIGS. 11 to 13 , in some embodiments, the guide 30 includes a main body 31 , and the main body 31 includes at least two first guide parts 311 and at least two second guide parts 313 . The guide portions 311 and the second guide portions 313 are arranged alternately in sequence. When the guide part 30 slides to the position where the first guide part 311 cooperates with the locking mechanism 50, under the action of the first guide part 311, the locking mechanism 50 connects the first support part 11 and the second support part. 13 is locked. When the guide part 30 slides to the position where the second guide part 313 cooperates with the locking mechanism 50, under the action of the second guide part 313, the locking mechanism 50 releases the first support part 11 and the locking mechanism 50. The locking between the second supports 13. Through the cooperation of the first guide part 311 and the second guide part 313, the second support member 13 can be driven to slide relative to the first support member 11, and at the same time, when locking is required, the locking mechanism 50 can be controlled to move the first support member 13 to the first support member 13. 11 is locked with the second support member 13. When it is necessary to adjust the bearing area of the pull-out device 100, the locking mechanism 50 is controlled to release the locking of the first support member 11 and the second support member 13, thereby improving the sophistication of the pull-out device 100. speed and reliability, bringing a better experience to users.

Optionally, the number of first guide parts 311 may be, but is not limited to, 2, 3, 4, 5, 6, etc. The number of first guide parts 311 determines the number of multi-level self-locking that the support assembly 10 can perform, that is, the number of second positions. The number of second positions is one less than the number of first guide parts 311. The number of first guide parts 311 is The greater the number, the greater the number of second positions.

Optionally, the number of second guide parts 313 may be, but is not limited to, 2, 3, 4, 5, 6, etc. The second guide portion 313 can be determined according to the number of the first guide portions 311 .

In the embodiment of FIG. 11 , the number of the first guide part 311 and the second guide part 313 is two. At this time, the number of the second position is one. In the embodiment of FIG. 12 , the number of the first guide part 311 and the second guide part 313 is three, and at this time, the number of the second position is one. In the embodiment of FIG. 13 , the number of the first guide parts 311 and the second guide parts 313 is three. At this time, the three first guide parts 311 correspond to the first position, the second position and the third position respectively; That is, the number of second positions is one, and the second support member 13 can also achieve self-locking when it is in the first position.

In some embodiments, when the guide member 30 slides from the position where the second guide part 313 cooperates with the locking mechanism 50 to the position where the first guide part 311 cooperates with the locking mechanism 50 , some components of the locking mechanism 50 are offset in a second direction (as shown by arrow B in FIG. 10 ) away from the guide member 30 , where the second direction is perpendicular to the first direction. In other words, compared to the position where the first guide part 311 cooperates with the locking mechanism 50 , when the guide part 30 slides to the second guide part 313 and cooperates with the locking mechanism 50 , the locking mechanism 50 Some of the components are closer to the guide 30 as a whole. On the contrary, when the guide member 30 slides from the position where the first guide part 311 cooperates with the locking mechanism 50 to the position where the second guide part 313 cooperates with the locking mechanism 50, the Some components of the locking mechanism 50 are offset toward the direction closer to the guide 30 along a second direction, where the second direction is perpendicular to the first direction. In this way, some components of the locking mechanism 50 are controlled to move up and down in the second direction through the guide 30, so that unlocking and locking can be realized. The structure is simple, and there is no need to add an additional control mechanism for the locking mechanism 50, and there is no need for manual operation to control the unlocking and locking. combine.

In some embodiments, the first guide part 311 is a first guide groove 311, the second guide part 313 is a second guide groove 313, and the first guide groove 311 and the second guide groove 313 are The number is at least two, and the number of the second guide parts 313 is at least two. The first guide grooves 311 and the second guide grooves 313 are alternately arranged in sequence and connected with each other; the guide member 30 is slidably arranged. In the matching groove 301 formed by the first guide groove 311 and the second guide groove 313; along the second direction, the width of the first guide groove 311 is greater than the width of the second guide groove 313, where , the second direction is perpendicular to the first direction. By arranging guide grooves of different widths at different positions on the guide member 30 , when the guide member 30 slides to different positions, the locking mechanism 50 is controlled to lock and unlock, thereby controlling the first support member 11 and the second support member 13 The locking and unlocking are simple in structure, and there is no need to add an additional locking mechanism 50 control mechanism, and there is no need for manual operation to control the unlocking and locking. In the embodiment of FIG. 11 , the number of first guide grooves 311 is 2, and the number of second guide grooves 313 is 2. The first guide grooves 311 and the second guide grooves 313 are arranged alternately in sequence and are connected with each other.

In some embodiments, the number of fitting grooves 301 may be one or two. When the number of the fitting grooves 301 is two, the two fitting grooves 301 are spaced apart along the second direction.

In some embodiments, along the first direction, the maximum sliding distance L of the second support member 13 relative to the guide member 30 satisfies the relationship L≥d, where d is the first guide portion 311 width along the first direction. In other words, the distance L between the first resisting surface 133 and the second resisting surface 135 is greater than or equal to the width of the first guide portion 311 along the first direction. In other words, the distance L between the first resisting surface 133 and the second resisting surface 135 is greater than or equal to the width of the first guide groove along the first direction. When the maximum sliding distance L of the second support member 13 relative to the guide member 30 is less than the width of the first guide portion 311 along the first direction, the guide member 30 has resisted the first resisting surface 133 or the second resisting surface 133 . The surface 135 can no longer slide relative to the second support member 13. At this time, the locking mechanism 50 is still in the position of mating with the first guide part 311, and the second guide part 313 has not yet moved to the position of mating with the locking mechanism 50. It is difficult to unlock the locking mechanism 50 and the first support member 11 and the second support member 13 cannot be unlocked.

Optionally, along the first direction, the maximum sliding distance L of the second support member relative to the guide member ranges from 2 mm ≤ L ≤ 5 mm. Specifically, the maximum sliding distance L of the second support member relative to the guide member may be, but is not limited to, 2mm, 2.5mm, 2.8mm, 3mm, 3.1mm, 3.3mm, 3.5mm, 3.8mm, 4.0mm, 4.3mm, 4.5mm, 4.8mm, 5.0mm. The maximum sliding distance of the second support member relative to the guide member cannot be too small. If the maximum sliding distance of the second support member relative to the guide member is too small, when the guide member 30 leaves the second position or the third position, position, the locking mechanism 50 may not be unlocked, the second support member 13 is difficult to move relative to the first support member 11, and the load-bearing area of the support assembly 10 cannot be changed, thereby changing the load-bearing area of the pull-out device 100, thereby causing the pull-out device 100 to move. When the pulling device 100 is applied to an electronic device, the display area of the flexible display screen of the electronic device is changed. If the maximum sliding distance of the second support member relative to the guide member is too large, when the pull-out device 100 is in the closed state, a larger sliding space of the guide member 30 needs to be reserved, which increases the number of pull-out devices 100 The volume in the closed state is not conducive to miniaturization of the pulling device 100 .

In some embodiments, the guide 30 further includes a resisting portion 33 . The resisting portion 33 is provided at one end of the main body 31 and is bent and connected to the main body 31 . The resisting portion 33 is The main body 31 is closer to the edge of the second support member 13; the resisting portion 33 can be slidably disposed in the limiting groove 131 of the second support member 13; when the guide member 30 faces away from the first When the support member 11 moves in one direction, the resisting portion 33 moves toward the first resisting surface 133 until the resisting portion 33 resists the first resisting surface 133 (as shown in FIG. 14 ), the guide member 30 drives the second support member 13 to move in a direction away from the first support member 11; conversely, when the guide member 30 moves in a direction close to the first support member 11 When moving, the resisting portion 33 moves in a direction close to the second resisting surface 135 , until the resisting portion 33 resists the second resisting surface 135 (as shown in FIG. 15 ), the guide 30 The second supporting member 13 is driven to move toward the direction closer to the first supporting member 11 . Through the cooperation of the resisting portion 33 and the limiting groove 131, the guide member 30 can be slidably connected to the second supporting member 13, and the sliding distance is limited within the space of the limiting groove 131. The structure is simple and compact.

Please refer to Figure 16. In some embodiments, the locking mechanism 50 includes a locking component 51 and a limiting component 53. The locking component 51 is disposed on the first support member 11 and is slidably connected to the guide member. 30. The limiting component 53 is provided on the second supporting member 13 , and the locking component 51 cooperates with the limiting component 53 to secure the first supporting member 11 and the second supporting member 13 To lock or unlock. Through the cooperation of the locking mechanism 50 and the guide member 30, when the second support member 13 is in the second position (as shown in Figure 17) and the third position (as shown in Figure 18), the first support member 11 and The second support member 13 is locked to prevent the second support member 13 from shaking relative to the first support member 11, and when it is hit or dropped by an external force, it can well disperse the external force and prevent the external force from being transmitted to the guide member 30 and the guide member 30. On a flexible display screen or other components that drive the guide 30 to move. In addition, when it is necessary to adjust the bearing area, the locking component 51 and the limiting component 53 can be quickly unlocked through the cooperation of the guide 30, and the structure is simple and compact.

Please refer to FIGS. 5 to 7 , 17 and 18 together. Further, when the locking component 51 is located at the first guide part 311 , the locking component 51 is in the first guide part 311 It is locked with the limiting component 53 to lock the first support member 11 with the second support member 13 (as shown in Figures 6, 7, 17 and 18). When the locking component 51 is located at the second guide part 313, the locking component 51 is unlocked from the limiting component 53 under the action of the second guide part 313 (as shown in FIG. 5), so as to release all the locking components. The first supporting member 11 and the second supporting member 13 are locked together. Through the cooperation of the first guide part 311 and the second guide part 313, the second support member 13 can be driven to slide relative to the first support member 11, and at the same time, when locking is required, the locking component 51 and the limiting component 53 can be controlled. The first support member 11 and the second support member 13 are locked together. When it is necessary to adjust the bearing area of the pull-out device 100, the locking component 51 is controlled to disengage from the limiting component 53 to release the first support member 11 and the second support member. 13's lock.

Further, when the guide 30 slides from the position where the second guide part 313 cooperates with the locking component 51 to the position where the first guide part 311 cooperates with the locking component 51, the The locking assembly 51 is deflected in a second direction away from the guide 30 , wherein the second direction is perpendicular to the first direction. In other words, compared to the position where the first guide part 311 cooperates with the locking component 51 , when the guide part 30 slides to the second guide part 313 and cooperates with the locking component 51 , the locking component 51 The whole is closer to the guide 30 . In this way, the guide 30 is used to control some components of the locking assembly 51 to move up and down in the second direction, so that unlocking and locking can be achieved. The structure is simple and manual unlocking and locking operations are not required.

Referring to FIG. 19 , optionally, the vertical distance s1 between the first guide part 311 and the limiting component 53 is less than the vertical distance s2 between the second guide part 313 and the limiting component 53 . In other words, the first guide part 311 is closer to the limiting component 53 than the second guide part 313, so that when the guide part 30 reaches the position where the first guide part 311 cooperates with the locking component 51, the locking component 51 can be It protrudes in the direction away from the guide member 30, is engaged with the limiting component 53, and cooperates with the limiting component 53 to achieve locking. When the guide member 30 moves to the position where the second guide portion 313 cooperates with the locking component 51, it can be The locking component 51 is deflected in a direction close to the guide 30 and disengaged from the limiting component 53 to achieve unlocking without adding additional locking and unlocking control mechanisms.

Please refer to Figures 20 to 22. In some embodiments, the locking component 51 includes a locking component 511 and a guide component 513. One end of the locking component 511 is connected to the guide component 513. The locking component 511 is connected to the guide component 513. The other end of 511 is used to cooperate with the limiting component 53 to achieve locking and unlocking of the support component 10 . The end of the guide component 513 away from the locking component 511 is slidably connected to the guide component 30 . When the second support member 13 is in the second position or the third position, under the action of the guide member 30 , the locking member 511 is engaged with the limiting component 53 to lock the first The support member 11 is locked with the second support member 13; when the second support member 13 leaves the second position or the third position, under the action of the guide member 30, the guide assembly 513 drives the The locking member 511 moves in a direction close to the guide member 30 so that the locking member 511 is separated from the limiting assembly 53, thereby unlocking the first support member 11 and the second support member 13. . In other words, when the guide member 30 slides to the position where the first guide part 311 cooperates with the guide assembly 513 (that is, the guide assembly 513 is slidingly connected to the first guide part 311), the locking member 511 moves in a direction away from the guide member 30 to lock the Connected to the limiting component 53, the first support member 11 and the second support member 13 are locked together. When the guide member 30 slides to the position where the second guide part 313 cooperates with the guide assembly 513 (that is, the guide assembly 513 is slidably connected to the second guide part 313), the locking member 511 moves toward the guide member 30 to disengage from the limiting position. The assembly 53 realizes the unlocking of the first support member 11 and the second support member 13 .

It can be understood that the locking component 51 extends parallel to the second direction. In other words, the locking component 51 extends perpendicular to the extension direction of the guide 30 (ie, perpendicular to the first direction).

In some embodiments, the locking component 51 further includes an elastic member 515 and a positioning member 517. The elastic member 515 is sleeved on part of the locking member 511, and the positioning member 517 is sleeved on the elastic member. 515 and is fixed on the surface of the first support member 11 facing the second support member 13. The elastic member 515 is limited in the positioning member 517 by the positioning member 517 and the locking member 511. When the third When the two supporting members 13 are in the second position or the third position, under the action of the guide member 30, the locking member 511 protrudes from the positioning member 517 and is engaged with the limiting component 53, so as to The first support member 11 and the second support member 13 are locked; when the second support member 13 leaves the second position or the third position, under the action of the guide member 30, the guide member 30 The assembly 513 drives the locking member 511 to move in a direction close to the guide member 30 and compresses the elastic member 515 so that the locking member 511 is separated from the limiting assembly 53 to achieve the first support. 11 and the second supporting member 13 are unlocked. Through the cooperation of the locking part 511, the elastic part 515 and the positioning part 517, when the elastic part 515 returns to deformation, the locking part 511 extends out of the positioning part 517 to engage the limiting component 53, and at the same time, the guiding component 513 can draw the , compressing the elastic member 515, causing the locking member 511 to retract into the positioning member 517 for unlocking. The entire solution has a simple, compact structure and is easy to implement.

Specifically, when the guide member 30 slides to the position where the first guide part 311 and the locking component 51 cooperate (that is, the second position or the third position, that is, when the first guide part 311 and the locking component 51 are slidingly connected), Since the first guide part 311 is closer to the limiting component 53 than the second guide part 313, the guide component 513 is closer to the limiting component 53 when it is in the position of mating with the first guide part 311. At this time, the elastic member 515, under the action of the elastic restoring force, pushes the locking member 511 to move in the direction away from the guide member 30, protrudes from the positioning member 517, and is engaged with the limiting component 53. When the guide member 30 slides to the second guide portion 313 When in the position of mating with the locking component 51 (that is, in any position other than the second position or the third position, that is, when the second guide part 313 is slidingly connected to the locking component 51), the guide component 513 moves closer to the guide member 30 move in the direction, pull the positioning member 517 to move in the direction close to the guide member, and retract into the positioning assembly, compress the elastic member 515, so that the locking member 511 is separated from the limiting assembly 53, thereby The first support member 11 and the second support member 13 are unlocked.

It can be understood that when the guide member 30 is in the position of the first guide part 311 and the locking component 51, the length of the elastic member 515 is greater than the elasticity when the guide part 30 is in the position of the second guide part 313 and the locking component 51. Piece 515 length. In other words, when the guide member 30 is in the position where the second guide part 313 is in sliding fit with the locking component 51 , the degree of compression of the elastic member 515 is greater than when the guide part 30 is in the position where the first guide part 311 is in sliding fit with the locking component 51 . The degree to which piece 515 is compressed. That is, when the guide member 30 is in the position of the first guide part 311 and the locking component 51, the elastic restoring force of the elastic member 515 is greater than when the guide part 30 is in the position of the second guide part 313 and the locking component 51. elastic recovery force.

Optionally, when the first guide portion 311 corresponds to the locking assembly 51, the elastic member 515 can be in a relaxed state (ie, not stretched or compressed), or can also be in a compressed state.

In some embodiments, the locking component 511 includes a connected locking part 5111 and a support part 5113. One end of the support part 5113 away from the locking part 5111 is connected to the guide component 513. The elastic member 515 It is sleeved on the support part 5113 and resists the locking part 5111. When the second support member 13 is in the second position or the third position, under the action of the guide member 30, the locking part 5111 is closed. The portion 5111 protrudes from the positioning member 517 and is engaged with the limiting component 53 to lock the first support member 11 and the second support member 13; when the second support member 13 leaves In the second position or the third position, under the action of the guide member 30, the guide assembly 513 drives the locking portion 5111 to move in a direction close to the guide member 30 and compresses the elastic member 515, so as to The locking portion 5111 is disengaged from the limiting component 53 , thereby unlocking the first support member 11 and the second support member 13 . When the second support member 13 leaves the second position or the third position, the locking portion 5111 is received in the positioning member 517 . Through the cooperation of the locking part 5111 and the positioning part 517, the elastic member 515 can be restricted in the positioning part 517 regardless of whether it is in an extended or compressed state, and the locking part 5111 can be driven by the elastic restoring force of the elastic part 515. For locking, the structure is simple, compact and easy to implement.
