[0041] The utility model discloses the realization, functional characteristics and advantages will combine embodiment, refer to the drawing further explanation. Specific implementation

[0042] The technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of the utility model protection.

[0043] It should be explained that if the embodiment of the utility model has involved directionality indication (such as up, down, left, right, front, back …), then the directionality indication is only used to explain the relative position relationship, movement condition etc. between the components in a certain specific posture, if the specific posture changes, then the directionality indication also changes accordingly.

[0044] In addition, if the description of "first", "second" and the like is involved in the embodiments of the utility model, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one feature. In addition, if "and / or" or "and / or" appears throughout the text, it means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B simultaneously satisfy the scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary technical personnel in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0045] At present, the frame structure of the child bed usually includes a plurality of vertical rods and a surrounding rod arranged between two vertical rods. The user can realize the conversion between the folding state and the unfolded state of the frame structure by driving the plurality of vertical rods to move close to or away from each other. In this process, the surrounding rod also needs to be folded or unfolded, otherwise it will affect the smoothness of the state change of the frame structure. However, the folding and unfolding process of the surrounding rod is completed manually by the user, which undoubtedly increases the complexity of the user's operation, resulting in poor user experience.

[0046] From the analysis of the above problems, when the frame structure is converted between the folding state and the unfolded state, the user needs to manually drive the frame structure, so that the plurality of vertical columns are close to or away from each other. The premise is difficult to change, and the movement of the plurality of vertical columns can be considered to be associated with the movement of the surrounding rod folding or unfolding, so as to save the process of manually driving the movement of the surrounding rod by the user, so as to reduce the complexity of the user's operation of the frame structure state change.

[0047] Therefore, the utility model provides a folding frame and a child appliance. The application scene of the folding frame includes but is not limited to the child appliance, and the folding frame can also be used for placing sundries. When the folding frame is applied to the child appliance, the folding frame can at least improve the situation that the user's operation of the existing frame structure state change is relatively cumbersome.

[0050] According to Figures 1 to 3 The state change process of the folding frame 100 can be clearly understood, and in order to more clearly understand the connection relationship and position relationship of various components, please refer to Figures 4 to 8 In an embodiment of the present application, the folding frame 100 comprises a frame 1, a telescopic assembly 2 and a linkage mechanism 3, the frame 1 comprises a support frame 11 and an upper surrounding rod assembly 12, the support frame 11 comprises a plurality of columns 111, and the upper surrounding rod assembly 12 comprises a plurality of surrounding rods 121 which are rotatably connected between two columns 111 and rotatably connected in pairs, the plurality of surrounding rods 121 can be rotatably folded, and the plurality of columns 111 can be arranged close to or away from each other, so that the support frame 11 has a folded state and an unfolded state, wherein the plurality of surrounding rods 121 comprises two first surrounding rods 121a which are respectively rotatably connected with a hinge seat 122; the telescopic assembly 2 has a mounting seat 22 and a telescopic part 21 which can be telescopically arranged relative to the mounting seat 22, one of the mounting seat 22 and the telescopic part 21 is rotatably connected with the hinge seat 122, and the other is rotatably connected with one of the first surrounding rods 121a, the telescopic part 21 has a first position and a second position on its telescopic travel, when in the first position, the first surrounding rod 121a is rotatably folded relative to the hinge seat 122, and when in the second position, the first surrounding rod 121a is rotatably opened relative to the hinge seat 122; the linkage mechanism 3 is drivingly connected between the telescopic part 21 and the support frame 11, so that when the support frame 11 is in the unfolded state, the telescopic part 21 is in the second position, and when the support frame 11 is in the folded state, the telescopic part 21 is in the first position.

[0051] It should be noted that the support frame 11 comprises a plurality of columns 111, the plurality of columns 111 are usually arranged along the circumferential direction of the support frame 11 and extend along the up-down direction, when the plurality of columns 111 are away from each other, an accommodation space can be formed therebetween, which can be used for children or babies to lie down or for sundries to be placed, and when the plurality of columns 111 are close to each other, the folding frame 100 can be converted to the folded state, thereby facilitating storage; the number of columns 111 arranged can be various, for example, please refer to Figure 4When the four posts 111 are provided, the frame 1 is in a square structure in the top view, and when more posts 111 are provided, the frame 1 is in a polygon structure in the top view. The number of the posts 111 included in the support frame 11 is not limited in the embodiment.

[0052] The upper rail assembly 12 is arranged between two adjacent posts 111 and can separate the containing space of the fence from the external space, i.e., play the role of the fence. The number of the rails 121 can be two, three, four or more. The "two-by-two rotation connection of the multiple rails 121" means that two adjacent rails 121 are rotationally connected at the ends to make the upper rail assembly 12 in a strip shape, and finally the free ends of the two rails 121 at the ends are rotationally connected to the corresponding posts 111. It is worth mentioning that in the embodiment, the rotation axes of the multiple rails 121 are in the same direction as the rotation axes of the rails 121 at the ends and the corresponding posts 111, so that the multiple rails 121 can relatively rotate with the mutual moving away and approaching of the two posts 111. The "multiple rails 121 including two first rails 121a rotationally connected to a hinge seat 122" can be understood as that the two first rails 121a and the hinge seat 122 correspond to form a rail 121 hinge group. Multiple rail 121 hinge groups can be provided, and adjacent rail 121 hinge groups are also connected through the hinge seat 122. Only one rail 121 hinge group can also be provided, and the embodiment does not limit this.

[0053] The telescopic assembly 2 can drive the hinge seat 122 and the first rail 121a to relatively rotate and approach each other and relatively rotate and spread apart through the telescopic movement of the mounting seat 22 and the telescopic part 21, so that the two first rails 121a relatively rotate and fold and relatively rotate and spread apart. The specific structure of the telescopic assembly 2 is not limited in the embodiment, as long as it can drive the hinge seat 122 and the first rail 121a to relatively rotate.

[0054] The linkage mechanism 3 is used to drive the support frame 11 and the telescopic part 21, and the purpose is to link the unfolding and folding of the support frame 11 with the telescopic movement of the telescopic part 21, so that the telescopic part 21 can move correspondingly when the user drives the support frame 11 to unfold or fold, thereby making the two first surrounding rods 121a automatically move away from or close to each other. It can be understood that there is relative movement between the support frame 11 during unfolding and folding, and the relative movement provides the power source for the movement of the telescopic part 21. The specific structure of the linkage mechanism 3 is not limited in the embodiment, as long as it can associate the movement of the support frame 11 with the movement of the telescopic part 21.

[0055] The technical scheme provided by the utility model, through setting telescopic assembly 2 between first surrounding rod 121a and hinged seat 122, then drive support frame 11 and make telescopic part 21 in telescopic assembly 2 drive connection together through linkage mechanism 3, when drive support frame 11 changes from folding state to unfolding state, telescopic part 21 can move to second position, make first surrounding rod 121a and hinged seat 122 be in relatively rotating unfolding state, namely two first surrounding rods 121a can unfold automatically with corresponding two stand 111 moving away from each other, when drive support frame 11 changes from unfolding state to folding state, telescopic part 21 can move to first position, make first surrounding rod 121a and hinged seat 122 be in relatively rotating folding state, namely two first surrounding rods 121a can fold automatically with two stand 111 moving close to each other, through the setting of linkage mechanism 3, increase the correlation degree of the action of two first surrounding rods 121a and support frame 11, user only needs to drive support frame 11 to move to complete the unfolding and folding of frame 1 smoothly, need not to operate the action of two first surrounding rods 121a additionally, reduce the operation difficulty, improve the situation that user operates the structure of existing frame 1 to change state more complicated.

[0056] It can be understood that in the above embodiment, the telescopic assembly 2 can be provided only for one of the first surrounding rods 121a. In this case, although the hinged seat 122 only actively rotates relative to the first surrounding rod 121a, it should still be recognized as contributing to the overall expansion or folding of the surrounding rods 121. However, in order to further improve the linkage effect of the two first surrounding rods 121a with the support frame 11, please refer to Figures 1 to 4In some embodiments, the telescopic assembly 2 is provided for each of the two first surrounding rods 121a. In this case, the two telescopic assemblies 2 can be synchronously telescoped to lift or lower the hinged seat 122 through the two first surrounding rods 121a. In the process of lifting the hinged seat 122, the two first surrounding rods 121a can form a straight rod (i.e. to achieve the purpose of self-expansion), and in the process of lowering the hinged seat 122, the two first surrounding rods 121a can be bent at the hinged seat 122 (i.e. to achieve the purpose of self-folding). Obviously, this solution can achieve better linkage effect of the two first surrounding rods 121a and the support frame 11.

[0057] Generally, in the process of normal use, the folding process of the upper surrounding rod assembly 12 generally belongs to the process of falling of the hinged seat 122, so as to ensure that the upper surrounding rod assembly 12 is folded between the plurality of standing columns 111 (instead of arching upward to protrude to the height of the plurality of standing columns 111), so that the overall volume of the folded folding frame 100 is smaller.

[0058] The above embodiments do not limit the specific telescopic state of the telescopic part 21 at the first position and the second position. For example, when the telescopic part 21 is at the first position, it can be in a retracted state relative to the mounting seat 22. To achieve this state, the connection point of the first surrounding rod 121a and the telescopic part 21 or the mounting seat 22 can be arranged on the outer side of the first surrounding rod 121a, i.e. on the side of the first surrounding rod 121a that is upward when the first surrounding rod 121a is in the expanded state. In this case, the connection point of the hinged seat 122 and the telescopic part 21 or the mounting seat 22 is arranged above the connection point of the hinged seat 122 and the first surrounding rod 121a. However, since the volume of the telescopic assembly 2 cannot be ignored, no matter how the telescopic part 21 is retracted relative to the mounting seat 22, it will hinder the folding of the first surrounding rod 121a relative to the hinged seat 122 to a certain extent, i.e. the folding degree of the first surrounding rod 121a is smaller, so that the overall volume of the folded folding frame 100 is still larger.

[0059] Therefore, please refer to Figures 1 to 3 In some embodiments, the first surrounding rod 121a has an inner side, which is the side of the first surrounding rod 121a that is downward when the first surrounding rod 121a is in the expanded state. The telescopic assembly 2 is arranged between the inner side of the first surrounding rod 121a and the hinged seat 122. When the telescopic part 21 is at the second position, the telescopic part 21 is in a retracted state relative to the mounting seat 22, and when the telescopic part 21 is at the first position, the telescopic part 21 is in an extended state relative to the mounting seat 22.

[0060] It should be noted that the inner side of the first surrounding rod 121a is relative to the folding frame 100, when the support frame 11 is in the unfolded state, the first surrounding rod 121a is also in the unfolded state, at this time, under the normal placement of the folding frame 100, the first surrounding rod 121a has a downward side, and this side is the inner side of the first surrounding rod 121a; the "telescopic assembly 2 is arranged between the inner side of the first surrounding rod 121a and the hinge seat 122" means that the connecting point of the mounting seat 22 or the telescopic part 21 in the telescopic assembly 2 and the hinge seat 122 is below the connecting point of the first surrounding rod 121a and the hinge seat 122; it is worth mentioning that in the present scheme, the state of the telescopic part 21 being in the second position is limited to the retracted state relative to the mounting seat 22, and the state of being in the first position is limited to the extended state relative to the mounting seat 22, that is, the telescopic part 21 in the retracted state corresponds to the unfolded state of the support frame 11, and the telescopic part 21 in the extended state corresponds to the folded state of the support frame 11.

[0061] According to the above technical scheme, the telescopic assembly 2 is arranged between the inner side of the first surrounding rod 121a and the hinge seat 122, when the telescopic part 21 is in the extended state, the support frame 11 is in the folded state, and correspondingly, the first surrounding rod 121a is in the folded state relative to the hinge seat 122, at this time, since the telescopic assembly 2 is on the inner side of the first surrounding rod 121a, there is no influence on the folding of the first surrounding rod 121a and the hinge seat 122, therefore, the folding degree of the first surrounding rod 121a and the hinge seat 122 is larger, and the overall volume of the folding frame 100 after folding is smaller; when the telescopic part 21 is in the retracted state, the support frame 11 is in the unfolded state, and correspondingly, the first surrounding rod 121a is in the unfolded state relative to the hinge seat 122, at this time, there is still a large included angle between the hinge seat 122 and the first surrounding rod 121a, which can provide sufficient installation space for the telescopic assembly 2.

[0062] In the above embodiment, the specific mounting position of the telescopic part 21 and the mounting seat 22 is not limited, which includes the mode that the telescopic part 21 is rotationally connected to the first surrounding rod 121a, and the mounting seat 22 is rotationally connected to the hinge seat 122, please refer to Figures 4 to 6 In some embodiments, the telescopic part 21 is rotationally connected to the hinge seat 122; the mounting seat 22 is rotationally connected to the first surrounding rod 121a; the linkage mechanism 3 includes a cable 31 which is in transmission connection between the telescopic part 21 and the support frame 11.

[0063] It should be noted that the linkage mechanism 3 connects the telescopic part 21 and the support frame 11 through the cable 31 to perform power transmission during the operation of the support frame 11. The cable 31 itself usually needs to have a certain flexibility to be able to bend and deform, thereby adapting to the relative movement between the components. The material of the cable 31 can be an alloy material such as a steel wire rope, or a nylon material. The specific material of the present embodiment is not limited, as long as it has excellent bending deformation ability and sufficient tensile deformation ability.

[0064] According to the above technical solution, the cable 31 transmits power between the support frame 11 and the telescopic part 21, so that the power transmission is continuous, and the driving process is smooth without jamming during the driving of the support frame 11 to change the state.

[0065] The connection relationship between the telescopic part 21 and the mounting seat 22 has various cases, for example, the telescopic part 21 and the mounting seat 22 are arranged in a spaced manner, and the telescopic part 21 is only retracted towards the mounting seat 22 by the cable 31. However, in this case, it is difficult to ensure the position of the telescopic part 21 in the retracted state, and it is difficult to ensure that the hinge seat 122 and the corresponding first surrounding rod 121a maintain a consistent opening state when the folding frame 100 is in the unfolded state, resulting in unstable unfolding state of the folding frame 100. In view of this, please refer to Figure 6 In some embodiments, the mounting seat 22 is formed with a mounting groove 221; the telescopic part 21 is telescopically and slidably arranged in the mounting groove 221; and the cable 31 is inserted into the mounting groove 221 from the bottom wall of the mounting groove 221 to be connected to the telescopic part 21.

[0066] It should be noted that since the mounting seat 22 is mounted on the first surrounding rod 121a, it can be understood that the slot of the mounting groove 221 is arranged towards the hinge seat 122, and the telescopic part 21 is slidably arranged in the mounting groove 221 to be able to retract into the mounting groove 221 and extend out of the mounting groove 221. The plurality of telescopic assemblies 2 can be uniformly manufactured to ensure that the retraction amount of the telescopic part 21 is the same when the telescopic part 21 abuts against the bottom wall of the mounting groove 221 of the mounting seat 22.

[0067] According to the above technical scheme, the telescopic part 21 is installed in the installation groove 221 of the installation base 22, the installation groove 221 limits the movement stroke of the telescopic part 21, the retraction amount of the telescopic part 21 in the plurality of upper surrounding rod assemblies 12 is easy to control, so that the consistent opening state between the hinge base 122 and the corresponding first surrounding rod 121a when the folding frame 100 is in the unfolded state can be ensured, and the stable unfolded state of the folding frame 100 is ensured. By setting in this way, the traction path of the cable 31 passes through the installation base 22, so that the direction of the traction force of the cable 31 is consistent with the movement direction of the telescopic part 21, so that the traction force acts more directly, and the traction efficiency of the cable 31 is improved.

[0068] In combination with the above scheme of the cable 31, please refer to Figures 1 to 3 In some embodiments, the plurality of columns 111 includes a first column 111a, and the other end of the first surrounding rod 121a of the telescopic assembly 2 is rotationally connected with the first column 111a; the support frame 11 further includes a lower connecting rod assembly 112, the lower connecting rod assembly 112 includes a plurality of connecting rods 1121 rotationally connected between two columns 111 and rotationally connected with each other, and the plurality of connecting rods 1121 includes a first connecting rod 1121a rotationally connected with the first column 111a; wherein the cable 31 is drivingly connected with the telescopic part 21 and the first connecting rod 1121a.

[0069] It should be noted that the setting position of the lower connecting rod assembly 112 is usually close to the bottom of the column 111, and the extension direction of the plurality of columns 111 usually belongs to the up-down direction, so the main function of the column 111 is to support and does not have the function of bottoming, and the lower connecting rod assembly 112 is arranged close to the bottom of the column 111, which has the function of bottoming on the one hand, and can also drive the plurality of columns 111 to approach and move away from each other on the other hand.

[0070] Among them, the positional relationship of the two columns 111 can be adjacent in the circumferential direction of the surrounding frame, or opposite in the radial direction of the surrounding frame, no matter which two columns 111, there are a plurality of connecting rods 1121 rotationally connected with each other between them, but the rotation forms of the plurality of connecting rods 1121 between the two columns 111 in different relative positions are different, for example, in one of the cases, please refer to Figure 4 , Figure 4The four connecting rods 1121 are rotatably connected to the four columns 111 at one end and rotatably connected to a base 1122 at the other end. The four connecting rods 1121 can drive the four columns 111 to move synchronously towards or away from each other under the up and down movement of the base 1122. In this case, the connecting rods 1121 between two circumferentially adjacent columns 111 have a certain angle, and the two connecting rods 1121 between two diametrically opposite columns 111 are in the same extension direction. Similarly, the four columns 111 can be analyzed in another case. In this case, the circumferentially adjacent two columns 111 can be rotatably connected by two connecting rods 1121 end to end. The connecting rods 1121 form a hinge point. In this way, four hinge points are formed between the four columns 111. The four hinge points are connected to the base 1122 by four additional connecting rods 1121. The four columns 111 can be driven to move synchronously towards or away from each other under the up and down movement of the base 1122. In this case, the connecting rods 1121 between two circumferentially adjacent columns 111 are in the same direction, and the connecting rods 1121 between two diametrically opposite columns 111 have a certain angle between each other.

[0071] It should be noted that the surrounding rods 121 at the end of the telescopic assembly 2 are rotatably connected to the columns 111. Therefore, “the other end of the first surrounding rod 121a of the telescopic assembly 2 is rotatably connected to the first column 111a” means that the telescopic assembly 2 only includes two first surrounding rods 121a. “The plurality of connecting rods 1121 includes a first connecting rod 1121a rotatably connected to the first column 111a” means that the first connecting rod 1121a is at the end of the plurality of connecting rods 1121 and is used to connect the first column 111a.

[0072] According to the above technical solution, the lower link assembly 112 includes a plurality of connecting rods 1121 arranged between the two upright columns 111, the actions of the plurality of upright columns 111 can be associated together through the plurality of connecting rods 1121, thereby playing a role in synchronously driving the plurality of upright columns 111 to approach or move away, and therefore, the lower link assembly 112 also generally acts as a point of external driving force; when the plurality of connecting rods 1121 between the two upright columns 111 are mutually propped open, the two upright columns 111 move away from each other, and the power can be efficiently transmitted from the connecting rods 1121 to the telescopic part 21 through the cable 31; when the support frame 11 is unfolded, the user only needs to drive the lower link assembly 112 to unfold the movable part, and the upper surrounding rod assembly 12 can be driven by the cable 31 to spontaneously make propping open movements; when the support frame 11 is folded, the user only needs to drive the lower link assembly 112 to fold the movable part, and since the cable 31 loses the traction force source of the connecting rods 1121, the telescopic part 21 cannot be maintained in the retracted state, and the upper surrounding rod assembly 12 spontaneously makes folding movements under the action of the self-weight of the first surrounding rod 121a.

[0073] The cable 31 is in transmission connection with the first connecting rod 1121a associated with the same first upright column 111a and the telescopic part 21, when the first connecting rod 1121a rotates and unfolds relative to the first upright column 111a, the support frame 11 changes to the unfolded state, and the cable 31 can make traction movements along with the rotating movements of the first connecting rod 1121a, thereby driving the telescopic part 21 to make corresponding telescopic movements.

[0074] Further, please refer to Figure 7 In some embodiments, the first upright column 111a includes a first connecting part 1111 for rotationally connecting the corresponding first surrounding rod 121a, and the cable 31 is arranged around the first connecting part 1111. It should be noted that the first connecting part 1111 is generally above the second connecting part 1112, so that the upper surrounding rod assembly 12 is above the lower link assembly 112, and the first connecting part 1111 includes but is not limited to the top corner of the first upright column 111a.

[0075] In other embodiments, the first upright column 111a includes a second connecting part 1112 for rotationally connecting the first connecting rod 1121a, and the cable 31 is arranged around the second connecting part 1112. It should be noted that the second connecting part 1112 includes but is not limited to the support leg of the first upright column 111a.

[0076] Please refer to Figure 5 and Figure 7In some embodiments, the first stand 111a is hollow, and the cable 31 passes through the inner cavity of the first stand 111a. It should be noted that the "hollow first stand 111a" can be understood as the first stand 111a being through in the extension direction, for example, the first stand 111a contains a standpipe, or it can be understood as the first stand 111a being hollow only in a section corresponding to the cable 31. According to the above technical solution, the cable 31 is arranged to pass through the inner cavity of the first stand 111a, which can hide the extension section of the cable 31 in the first stand 111a, thereby reducing the adverse effect of the existence of the cable 31 on the appearance of the folding frame 100, and the cable 31 is protected by the first stand 111a and is not easily disturbed by external structures.

[0077] The above three parallel technical solutions "the first stand 111a includes a first connecting part 1111 for rotationally connecting the corresponding surrounding rod 121, and the cable 31 passes through the first connecting part 1111", "the first stand 111a includes a second connecting part 1112 for rotationally connecting the first connecting rod 1121a, and the cable 31 passes through the second connecting part 1112", and "the first stand 111a is hollow, and the cable 31 passes through the inner cavity of the first stand 111a" can be set up one by one, two by two, or simultaneously. Obviously, when they are set up simultaneously, the extension path of the cable 31 passes through the surrounding rod 121, the first connecting part 1111, the first stand 111a, the second connecting part 1112, the first connecting rod 1121a, and the first surrounding rod 121a, and is not easily disturbed by external structures, ensuring the smooth state transition of the folding frame 100, and reducing the adverse effect of the existence of the cable 31 on the appearance of the folding frame 100, and the cable 31 is protected by the first stand 111a and is not easily disturbed by external structures.

[0078] Since the cable 31 needs to be connected to the first connecting rod 1121a through the first connecting part 1111 and the second connecting part 1112, the first connecting part 1111 and the second connecting part 1112 will hinder the traction movement of the cable 31. In view of this, please refer to Figure 7 and Figure 8 In some embodiments, a wire tube 32 is arranged between the mounting seat 22 and the second connecting part 1112, and the cable 31 is arranged in the wire tube 32. In this way, by wrapping the wire tube 32 outside the cable 31, the sliding contact between the cable 31 and the first connecting part 1111 and the second connecting part 1112 can be isolated, the sliding resistance can be reduced, and the smoothness of the linkage between the telescopic part 21 and the first connecting rod 1121a can be improved.

[0079] In combination with the above embodiments, in consideration of the visual experience of the user, if the cable 31 is externally arranged outside the first surrounding rod 121a, the appearance of the folding frame 100 will inevitably be affected, and the traction of the cable 31 will also be hindered by external structures. In view of this, please refer to Figure 5 , the first surrounding rod 121a is hollow, and the cable 31 passes through the inner cavity of the first surrounding rod 121a.

[0080] It should be noted that the "hollow first surrounding rod 121a" can be understood as the first surrounding rod 121a being through in the extension direction, for example, the first surrounding rod 121a contains a surrounding pipe, or it can be understood as the first surrounding rod 121a being hollow only in a section corresponding to the cable 31.

[0081] According to the above technical solution, the cable 31 is arranged through the inner cavity of the first surrounding rod 121a, which can hide the extension section of the cable 31 in the first surrounding rod 121a, thereby reducing the adverse effect of the existence of the cable 31 on the appearance of the folding frame 100, and the cable 31 is protected by the first surrounding rod 121a and is not easily disturbed by external structures.

[0082] In combination with the arrangement position of the telescopic assembly 2 on the first surrounding rod 121a, please refer to Figure 6 In some embodiments, the hinge seat 122 has a driving end at the bottom, the driving end protrudes towards the inner side of the first surrounding rod 121a to form a driving protrusion 1221, and the driving protrusion 1221 is used for rotationally connecting one of the mounting seat 22 and the telescopic part 21.

[0083] It should be noted that in order to realize the rotation folding of the telescopic assembly 2 driving the hinge seat 122 relative to the first surrounding rod 121a, it is necessary to ensure that the connection point of the telescopic assembly 2 and the hinge seat 122 and the connection point of the first surrounding rod 121a and the hinge seat 122 have a height difference, and at the same time, when the support frame 11 is in the unfolded state, the two first surrounding rods 121a also need to maintain the unfolded state with the hinge seat 122. This state is maintained mainly by the contraction of the telescopic assembly 2, and a larger contraction force arm can obviously reduce the contraction pressure of the telescopic assembly 2.

[0084] According to the above technical solution, the driving protrusion 1221 is formed at the bottom of the hinge seat 122, and the protrusion of the driving protrusion 1221 is towards the inner side of the first surrounding rod 121a, thereby increasing the included angle between the contraction direction of the telescopic assembly 2 and the hinge seat 122, that is, increasing the contraction force arm of the telescopic assembly 2, thereby reducing the contraction pressure of the telescopic assembly 2, and making the two first surrounding rods 121a more easily maintain the unfolded state with the hinge seat 122.

[0085] In some embodiments, the ends of the two first surrounding rods 121a away from the hinge seats 122 are respectively rotationally connected to the corresponding columns 111.

[0086] It should be noted that, since the upper surrounding rod assembly 12 includes multiple surrounding rods 121, only the surrounding rods 121 at the ends are rotationally connected to the corresponding columns 111, and in the present scheme, the ends of the first surrounding rods 121a away from the hinge seats 122 are directly rotationally connected to the corresponding columns 111, which means that the number of surrounding rods 121 in the upper surrounding rod assembly 12 is two, and both are first surrounding rods 121a.

[0087] According to the above technical scheme, the upper surrounding rod assembly 12 is arranged to be composed of two first surrounding rods 121a, which can reduce the degrees of freedom of the upper surrounding rod assembly 12 without affecting the relative movement of the adjacent two columns 111, and the reduction of the degrees of freedom also means the improvement of the reliability of the upper surrounding rod assembly 12. It can be understood that, in the unfolded state of the surrounding frame, the rotation between the two first surrounding rods 121a and the hinge seats 122 is fixed, which can limit the relative movement of the multiple columns 111, and is beneficial to maintaining the stability of the surrounding frame.
