[0039] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0040] It should be noted that if the embodiments of the utility model involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture, and if the specific posture changes, the directional indications will also change accordingly.

[0041] 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.

[0042] 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.

[0043] 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 conversion.

[0044] Therefore, the utility model provides a folding frame and a child appliance. The application scenarios of the folding frame include but are not limited to child appliances, and the folding frame can also be used for placing sundries. When the folding frame is applied to a child appliance, the folding frame can at least improve the situation that the user's operation of the existing frame structure state conversion is relatively cumbersome.

[0045] Among them, Figure 1 The structure schematic view of the folding frame (the frame is in the unfolded state) provided by the utility model is shown in the figure; Figure 2 The structure schematic view of the folding frame (the frame is in the intermediate state) provided by the utility model is shown in the figure;

[0047] According to Figures 1 to 3 The folding frame 100 state change process provided by the utility model can be clearly understood, in order to more clearly understand the connecting relationship and positional relationship of various components, please refer to Figure 4 And Figure 5 In an embodiment of the utility model, the folding frame 100 includes frame 1, drive assembly 2 and linkage mechanism 3, frame 1 includes support frame 11 and upper surrounding rod assembly 12, support frame 11 includes multiple stand columns 111, and upper surrounding rod assembly 12 includes multiple surrounding rods 121 rotatably connected between two stand columns 111 and rotatably connected in pairs, multiple surrounding rods 121 can be folded, and multiple stand columns 111 can be arranged close to each other and away from each other, so that support frame 11 has a folded state and an unfolded state, wherein multiple surrounding rods 121 include two first surrounding rods 121a rotatably connected with a hinged seat 122 respectively;Drive assembly 2 includes driving part 21 and connecting part 22, driving part 21 is movably arranged on a first surrounding rod 121a along the length direction of the first surrounding rod 121a, one end of connecting part 22 is rotatably connected with driving part 21, and the other end is rotatably connected with hinged seat 122, driving part 21 has a first position and a second position on its movable stroke, when in the first position, the first surrounding rod 121a is folded relative to the hinged seat 122, and when in the second position, the first surrounding rod 121a is unfolded relative to the hinged seat 122;Linkage mechanism 3 is drivingly connected between driving part 21 and support frame 11, so that driving part 21 is in the second position when support frame 11 is in the unfolded state, and driving part 21 is in the first position when support frame 11 is in the folded state.

[0048] It should be noted that the support frame 11 includes multiple stand columns 111, the arrangement of multiple stand columns 111 is usually along the circumferential direction of the support frame 11 and extends along the up-down direction, when multiple stand columns 111 are away from each other, an accommodation space can be formed therebetween, which can be used for children or infants to lie down or for sundries to be placed;When multiple stand columns 111 are close to each other, the folding frame 100 can be converted to the folded state, thereby facilitating storage;The number of stand columns 111 can be various, for example, please refer to Figure 1 And Figure 4 When four stand columns 111 are arranged, the frame 1 is in a square structure in the top view, and when more stand columns 111 are arranged, the frame 1 is in a polygonal structure in the top view, and the number of stand columns 111 included in the support frame 11 is not limited in the embodiment.

[0049] Wherein, since the main role of the support frame 11 is to support, and does not have the role of fence, and the upper surrounding rod assembly 12 is arranged between two adjacent stand columns 111, which can play the role of separating the containing space of the fence from the external space, that is, the role of the fence; wherein, the number of surrounding rods 121 can be two, three, four or even more, and "a plurality of surrounding rods 121 are rotationally connected two by two" means that the two surrounding rods 121 adjacent to each other are rotationally connected between the ends, so that the upper surrounding rod assembly 12 as a whole is in a strip shape, and finally the free ends of the two surrounding rods 121 at the ends are respectively rotationally connected to the corresponding stand columns 111; it is worth mentioning that in the embodiment, the rotation axes of the plurality of surrounding rods 121 are in the same direction as the rotation axes of the surrounding rods 121 at the ends and the corresponding stand columns 111, so as to ensure that the plurality of surrounding rods 121 relatively rotate with the mutual moving away and approaching of the two stand columns 111; "the plurality of surrounding rods 121 include two first surrounding rods 121a respectively rotationally connected with a hinged seat 122" can be understood as that the two first surrounding rods 121a correspond to form a surrounding rod 121 hinged group with the hinged seat 122, and a plurality of groups of the surrounding rod 121 hinged group can be provided, and two adjacent surrounding rod 121 hinged groups are also connected through the hinged seat 122, and only one group of the surrounding rod 121 hinged group can be provided, and the embodiment does not limit this.

[0050] Wherein, the role of the driving assembly 2 is to drive the movement of the first surrounding rod 121a by the driving part 21, drive the hinged seat 122 and the first surrounding rod 121a to rotate and close to each other and to rotate and spread apart, so that the two first surrounding rods 121a rotate and fold and rotate and spread apart; the specific structure of the driving assembly 2 is not limited in the embodiment, as long as it can drive the relative rotation of the hinged seat 122 and the first surrounding rod 121a.

[0051] Wherein, the role of the linkage mechanism 3 is to drive the connection of the support frame 11 and the driving part 21, and the purpose is to link the unfolding and folding movement of the support frame 11 with the movement of the driving part 21 along the first surrounding rod 121a, so that when the user drives the support frame 11 to unfold or fold, the driving part 21 can make corresponding movements, so that the two first surrounding rods 121a spontaneously spread apart or close to each other; it can be understood that during the unfolding and folding process of the support frame 11, there is relative movement between the structures, and the relative movement provides the power source for the movement of the driving part 21, and 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 driving part 21.

[0052] The utility model discloses a technical scheme, through setting up drive assembly 2 between first surrounding rod 121a and hinged seat 122, then drive part 21 in drive assembly 2 is driven together with support frame 11 through linkage mechanism 3, when drive support frame 11 changes from folding state to unfolding state, drive part 21 can be active to second position, make first surrounding rod 121a with hinged seat 122 be in relatively rotating unfolding state, namely two first surrounding rod 121a can be unfolded with the mutual separation of corresponding two stand 111, when drive support frame 11 changes from unfolding state to folding state, drive part 21 can be active to first position, make first surrounding rod 121a with hinged seat 122 be in relatively rotating folding state, namely two first surrounding rod 121a can be folded with the mutual approach of two stand 111, through the setting of linkage mechanism 3, increase the correlation of the action of two first surrounding rod 121a and support frame 11, and user only needs to drive support frame 11 action to complete the unfolding and folding of the whole frame 1, need not additional operation two first surrounding rod 121a action, reduce the operation difficulty, improve the user operation existing frame 1 structure change state more complicated situation.

[0053] It can be understood that in the above embodiment, the drive assembly 2 can be set 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 considered to contribute to the overall expansion or folding of the multiple surrounding rods 121. However, to further improve the linkage effect of the two first surrounding rods 121a with the support frame 11, please refer to Figures 1 to 3 , and Figure 5 In some embodiments, the drive assembly 2 is provided for both first surrounding rods 121a. At this time, the two drive assemblies 2 can be synchronously driven to lift or lower the hinged seat 122 through the two first surrounding rods 121a. During the lifting of the hinged seat 122, the two first surrounding rods 121a can form a straight rod (i.e., to achieve the purpose of unfolding), and during the lowering of 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 folding). Obviously, this solution can achieve better linkage effect of the two first surrounding rods 121a with the support frame 11.

[0054] Generally, during normal use, the folding process of the upper surrounding rod assembly 12 is generally the process of the hinged seat 122 falling. In this way, the upper surrounding rod assembly 12 can be folded between the multiple stand 111 (instead of arching upwards and protruding above the multiple stand 111), so that the overall volume of the folded frame 100 is smaller.

[0055] The above embodiments do not limit the specific activity state of the driving part 21 in the first position and the second position, which includes that when the driving part 21 is in the first position, the driving part 21 can be away from the hinge seat 122, to achieve this state, the connecting point of the driving part 21 and the connecting part 22 can be arranged outside the first surrounding rod 121a, that is, the upper side of the first surrounding rod 121a in the expanded state, at this time, the connecting point of the hinge seat 122 and the connecting part 22 is arranged above the connecting point of the hinge seat 122 and the first surrounding rod 121a, but due to the existence of the driving assembly 2 itself, no matter how the driving part 21 is away from the hinge seat 122, the connecting part 22 existing therebetween will hinder the folding of the first surrounding rod 121a to the hinge seat 122 to a certain extent, that is, the folding degree of the first surrounding rod 121a in this scheme is smaller, so that the overall volume of the folding frame 100 after folding is still larger.

[0056] In view of this, please refer to Figures 1 to 3 In some embodiments, the first surrounding rod 121a has an inner side, the inner side of the first surrounding rod 121a is the lower side of the first surrounding rod 121a in the expanded state; the driving assembly 2 is arranged between the inner side of the first surrounding rod 121a and the hinge seat 122; when the driving part 21 is in the first position, the driving part 21 is arranged close to the hinge seat 122, and when the driving part 21 is in the second position, the driving part 21 is arranged away from the hinge seat 122.

[0057] It should be noted that the inner side of the first surrounding rod 121a is for the folding frame 100, when the support frame 11 is in the unfolded state, the first surrounding rod 121a also corresponds to the expanded state, at this time, under the normal placement of the folding frame 100, the first surrounding rod 121a has a lower side, which is the inner side of the first surrounding rod 121a; “the driving 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 connecting part 22 and the hinge seat 122 in the driving assembly 2 is below the connecting point of the first surrounding rod 121a and the hinge seat 122; It is worth mentioning that in this scheme, the state of the driving part 21 in the second position is limited to the state of being away from the hinge seat 122, and the state of the driving part 21 in the first position is limited to the state of being close to the hinge seat 122, that is, the state of the driving part 21 being away from corresponds to the folding state of the support frame 11, and the state of the driving part 21 being close corresponds to the folding state of the support frame 11.

[0058] According to the above technical scheme, the driving assembly 2 is arranged between the inner side of the first surrounding rod 121a and the hinge seat 122. When the driving part 21 is in the far-away 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 driving assembly 2 is arranged on the inner side of the first surrounding rod 121a, the folding of the first surrounding rod 121a and the hinge seat 122 is not affected, and therefore, the folding degree of the first surrounding rod 121a and the hinge seat 122 is larger, and the overall volume of the folded folding frame 100 is smaller.

[0059] In combination with the arrangement position of the driving assembly 2, please refer to Figures 1 to 3 In some embodiments, the support frame 11 further comprises a lower connecting rod assembly 112, the lower connecting rod assembly 112 comprising a plurality of connecting rods 1121 rotationally connected between two upright columns 111 and rotationally connected with each other; wherein the linkage mechanism 3 is drivingly connected between the driving part 21 and one of the connecting rods 1121.

[0060] It should be noted that the arrangement position of the lower connecting rod assembly 112 is usually close to the bottom of the upright column 111. The extension direction of the plurality of upright columns 111 is usually the up-down direction, and therefore the main function of the upright column 111 is to support and does not have the function of bottoming. The lower connecting rod assembly 112 is arranged close to the bottom of the upright column 111, which has the function of bottoming on the one hand and can also drive the plurality of upright columns 111 to move close to or away from each other on the other hand.

[0061] Among them, the positional relationship of the two upright columns 111 can be adjacent in the circumferential direction of the surrounding frame, or opposite in the radial direction of the surrounding frame. Regardless of which two upright 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 upright columns 111 in different relative positions are different, for example, in one of the cases, please refer to Figure 4 , Figure 4The middle folding frame 100 comprises four upright columns 111 and four connecting rods 1121, one end of each of the four connecting rods 1121 corresponds to one of the four upright columns 111, and the other end is rotatably connected to one base 1122. Through the four connecting rods 1121, the four upright columns 111 can be driven to move synchronously closer to or farther away from each other. In this case, the connecting rods 1121 between two circumferentially adjacent upright columns 111 form a certain angle, and the two connecting rods 1121 between two diametrically opposite upright columns 111 are in the same extension direction. Similarly, in the case of four upright columns 111, in another case, two circumferentially adjacent upright columns 111 can also be connected by two connecting rods 1121 rotatably connected end to end. The connecting position of the two connecting rods 1121 forms a hinge point. In this way, four hinge points are formed between the four upright columns 111. Through the additional four connecting rods 1121, the four hinge points are connected to the middle base 1122. Under the up-and-down movement of the base 1122, the four upright columns 111 can also be driven to move synchronously closer to or farther away from each other. In this case, the connecting rods 1121 between two circumferentially adjacent upright columns 111 are in the same direction, and the multiple connecting rods 1121 between two diametrically opposite upright columns 111 form a certain angle between each other.

[0062] According to the above technical solution, the lower link assembly 112 comprises multiple connecting rods 1121 arranged between two upright columns 111. Through the multiple connecting rods 1121, the actions of the multiple upright columns 111 can be associated together, thereby playing a role in synchronously driving the multiple upright columns 111 to move closer to or farther away from each other. Therefore, the lower link assembly 112 usually also serves as the action point of the external driving force. When the multiple connecting rods 1121 between the two upright columns 111 are spread apart from each other, the two upright columns 111 move away from each other. Through the linkage mechanism 3, the power can be efficiently transmitted from the connecting rods 1121 to the driving part 21. When unfolding the support frame 11, the user only needs to drive the lower link assembly 112 to unfold and move, and the upper surrounding rod assembly 12 can be driven by the linkage mechanism 3 to spontaneously make a spreading movement. When folding the support frame 11, the user only needs to drive the lower link assembly 112 to fold and move, and the driving part 21 can be driven by the linkage mechanism 3 to move closer to the hinge seat 122. At the same time, under the action of the self-weight of the first surrounding rod 121a, the upper surrounding rod assembly 12 spontaneously makes a folding movement in cooperation with the movement of the driving part 21.

[0063] The number of connecting rods 1121 between the two upright columns 111 can be in various cases. Specifically, please refer to Figure 5In some embodiments, the plurality of upright columns 111 includes a first upright column 111a; the other end of the first surrounding rod 121a of the driving assembly 2 is rotationally connected to the first upright column 111a; the plurality of connecting rods 1121 includes a first connecting rod 1121a rotationally connected to the first upright column 111a; and the linkage mechanism 3 is in transmission connection with the driving part 21 and the first connecting rod 1121a.

[0064] It should be noted that, since only the surrounding rods 121 at the end of the upper surrounding rod assembly 12 are rotationally connected to the upright columns 111, “the other end of the first surrounding rod 121a of the driving assembly 2 is rotationally connected to the first upright column 111a” means that the upper surrounding rod assembly 12 only includes two first surrounding rods 121a; and “the plurality of connecting rods 1121 includes a first connecting rod 1121a rotationally connected to the first upright column 111a” means that the first connecting rod 1121a is at the end of the plurality of connecting rods 1121 and is used to be connected to the first upright column 111a.

[0065] According to the above technical solution, the linkage mechanism 3 is in transmission connection with the first connecting rod 1121a associated with the same first upright column 111a and the driving part 21, when the first connecting rod 1121a is rotationally unfolded relative to the first upright column 111a, the support frame 11 changes to the unfolded state, the linkage mechanism 3 can be in traction activity along with the rotational activity of the first connecting rod 1121a, thereby driving the driving part 21 to make an activity away from the hinge seat 122; and when the first connecting rod 1121a is rotationally folded relative to the first upright column 111a, the support frame 11 changes to the folded state, the linkage mechanism 3 can be in pushing activity along with the rotational activity of the first connecting rod 1121a, thereby pushing the driving part 21 to make an activity close to the hinge seat 122.

[0066] The above embodiments do not limit the specific structure of the linkage mechanism, in some embodiments, the linkage mechanism 3 includes a movable sleeve 31, a first linkage rod 32 and a second linkage rod 33, the movable sleeve 31 is sleeved on the first upright column 111a and is movably arranged up and down along the first upright column 111a; one end of the first linkage rod 32 is rotationally connected to the movable sleeve 31, and the other end is rotationally connected to the driving part 21, when the movable sleeve 31 is moved upward to a position, the first linkage rod 32 drives the driving part 21 to be arranged close to the hinge seat 122, when the movable sleeve 31 is moved downward to a position, the first linkage rod 32 drives the driving part 21 to be arranged away from the hinge seat 122; one end of the second linkage rod 33 is rotationally connected to the movable sleeve 31, and the other end is rotationally connected to the first connecting rod 1121a, when the first connecting rod 1121a is rotationally folded relative to the first upright column 111a, the second linkage rod 33 drives the movable sleeve 31 to move upward, when the first connecting rod 1121a is in the supporting state relative to the first upright column 111a, the second linkage rod 33 drives the movable sleeve 31 to move downward.

[0067] The linkage mechanism 3 comprises a movable sleeve 31, a first linkage rod 32 and a second linkage rod 33. The movable sleeve 31 is movably arranged along the first stand 111a. The first linkage rod 32 is rotatably connected to one end of the movable sleeve 31 and rotatably connected to the other end of the driving part 21. When the movable sleeve 31 is moved upward to a position, the first linkage rod 32 drives the driving part 21 to be arranged close to the hinged seat 122. When the movable sleeve 31 is moved downward to a position, the first linkage rod 32 drives the driving part 21 to be arranged away from the hinged seat 122. The second linkage rod 33 is drivingly connected between the movable sleeve 31 and the first connecting rod 1121a, and converts the rotation of the first connecting rod 1121a relative to the first stand 111a into the movement of the movable sleeve 31 relative to the first stand 111a in the upward and downward directions. When the first connecting rod 1121a is folded relative to the first stand 111a, the second linkage rod 33 drives the movable sleeve 31 to move upward. When the first connecting rod 1121a is in a supporting state relative to the first stand 111a, the second linkage rod 33 drives the movable sleeve 31 to move downward. It can be understood that the two ends of the second linkage rod 33 are arranged on the rotation axes of the movable sleeve 31 and the first connecting rod 1121a, and the rotation axes are arranged in the same direction as the rotation axes between the first connecting rod 1121a and the first stand 111a.

[0068] It should be noted that, since the first connecting rod 1121a and the first surrounding rod 121a are arranged in association with the first stand 111a, the power transmission between the first connecting rod 1121a and the first surrounding rod 121a inevitably needs to pass through the first stand 111a. The movable sleeve 31 is an intermediate power transmission component. The present embodiment only limits the movement direction of the movable sleeve 31 on the first stand 111a, and does not limit the specific structure of the movable sleeve 31. It can be understood that the two ends of the first linkage rod 32 are arranged on the rotation axes of the movable sleeve 31 and the driving part 21, and the rotation axes are arranged in the same direction as the rotation axes between the two first surrounding rods 121a.

[0069] According to the above technical solution, when the movable sleeve 31 moves upward along the first stand 111a, the driving part 21 can be pushed to be close to the hinged seat 122 under the driving of the first linkage rod 32. Under the driving of the connecting part 22, the hinged seat 122 can rotate relative to the first surrounding rod 121a to be folded, so that the movement of the first surrounding rod 121a can adapt to the unfolding movement of the surrounding frame, and ensure that the unfolding of the surrounding frame is smoothly performed. Furthermore, the installation and movement of the movable sleeve 31 fully utilize the first stand 111a. The movable sleeve 31 and the first stand 111a have a guiding effect in structure cooperation, so that no additional guiding structure is needed, the structure is simple, stable and reliable, and the power transmission efficiency is high.

[0070] It is worth mentioning that the connection between the driving assembly 2 and the first surrounding rod 121a and the hinge seat 122 is a movable connection, but since the first surrounding rod 121a, the hinge seat 122, the driving part 21 and the movable sleeve 31 are all rigid connection parts 22, it is relatively difficult to completely associate the movement of the driving part 21 along the first surrounding rod 121a, the rotation of the first surrounding rod 121a relative to the column 111 and the movement of the plurality of columns 111 relative to each other, and therefore there is a risk of jamming during the folding and unfolding of the folding frame 100. In view of this, please refer to Figures 1 to 3 In some embodiments, the connection part 22 is connected with the hinge seat 122 through a pin shaft 221 which is movable in the opposite direction of the corresponding two columns 111.

[0071] It should be noted that the opposite direction of the two columns 111 can also be considered as the opposite direction of the connection points of the two first surrounding rods 121a and the hinge seat 122. In the embodiments of the present application, the main function of the driving assembly 2 is to drive the hinge seat 122 to rotate relative to the first surrounding rod 121a to expand when the support frame 11 is in the unfolded position, so as to adapt to the unfolded state of the support frame 11 and maintain the expanded state of the upper surrounding rod assembly 12 to play the role of fence protection. In the present scheme, the pin shaft 221 is movable in the opposite direction of the two columns 111 and has an inner limit position close to the corresponding first surrounding rod 121a. When the pin shaft 221 is at the limit position, the upper surrounding rod assembly 12 can be maintained in the expanded state.

[0072] According to the above technical scheme, the pin shaft 221 between the hinge seat 122 and the connection part 22 is arranged to be movable in the opposite direction of the two columns 111. During the folding and unfolding of the folding frame 100, the deviation of the relative movement between the parts can be compensated by the movement of the pin shaft 221, so as to ensure the smooth folding and unfolding of the folding frame 100.

[0073] Specifically, a mounting sliding groove is formed on the hinge seat 122, which is elongated in the opposite direction of the two columns 111; the pin shaft 221 is movably arranged in the mounting sliding groove.

[0074] In combination with the arrangement position of the driving assembly 2 on the first surrounding rod 121a, please refer to Figure 5 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 connected with the connection part 22.

[0075] It should be noted that, in order to realize the folding of the driving 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 driving assembly 2 and the hinge seat 122 has a height difference with the connection point of the first surrounding rod 121a and the hinge seat 122, 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. The state is maintained mainly through the active driving of the driving assembly 2, and a larger driving torque can obviously reduce the driving pressure of the driving assembly 2.

[0076] According to the above technical solution, the driving protrusion 1221 is formed at the bottom of the hinge seat 122. Since the protrusion of the driving protrusion 1221 is directed towards the inner side of the first surrounding rod 121a, the driving direction of the driving assembly 2 and the hinge seat 122 can be increased, that is, the driving torque of the driving assembly 2 is increased, thereby reducing the driving pressure of the driving assembly 2, so that the two first surrounding rods 121a are more easily maintained in the unfolded state with the hinge seat 122.

[0077] In the above embodiment, only the active mode of the driving part 21 on the first surrounding rod 121a is limited, and the specific structure of the driving part 21 is not limited. Please refer to Figure 4 and Figure 5 In some embodiments, the driving part 21 includes a driving sleeve 211, and the driving sleeve 211 is sleeved on the first surrounding rod 121a.

[0078] It should be noted that the driving part 21 is provided as a driving sleeve 211, which aims to cooperate with the first surrounding rod 121a to realize the guiding activity along the extension direction of the first surrounding rod 121a.

[0079] According to the above technical solution, by connecting the driving part 21 to the first surrounding rod 121a through the driving sleeve 211, the guiding effect of the structure cooperation between the driving sleeve 211 and the first surrounding rod 121a is achieved, so that the additional guiding structure is omitted, and the overall structure of the folding frame 100 is simplified.

[0080] In some embodiments, the ends of the two first surrounding rods 121a away from the hinge seat 122 are respectively rotationally connected to the corresponding stand columns 111.

[0081] It should be noted that, since the upper surrounding rod assembly 12 includes a plurality of surrounding rods 121, only the surrounding rods 121 at the end are rotationally connected to the corresponding stand columns 111, and in the present scheme, the end of the first surrounding rod 121a away from the hinge seat 122 is directly rotationally connected to the corresponding stand column 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.

[0082] According to the technical scheme, the upper surrounding rod assembly 12 is composed of two first surrounding rods 121a, and the freedom degree of the upper surrounding rod assembly 12 can be reduced without affecting the relative movement of the two adjacent upright columns 111, and the reduction of the freedom degree means that the reliability of the upper surrounding rod assembly 12 is improved, and it can be understood that the rotation between the two first surrounding rods 121a and the hinge seat 122 is fixed in the unfolded state of the surrounding frame, which can limit the relative movement of the plurality of upright columns 111, and is beneficial to maintaining the stability of the surrounding frame.
