Description

Technical Field

[0001] This application relates to the field of fan technology, and in particular to a bracket structure and a fan. Background Technology

[0002] In related technologies, some fan products lack a folding and storage function, making them inconvenient to store in winter and taking up space. Additionally, some products only offer height adjustment via a telescopic rod, resulting in a limited adjustment range that cannot meet the needs of users at different heights, such as those on beds, dining tables, sofas, or while standing. Utility Model Content

[0003] Therefore, it is necessary to provide a bracket structure and fan to address the issue that fans cannot meet the needs of users in multiple scenarios.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a support structure, including:

[0006] Head assembly;

[0007] The fuselage assembly is telescopically adjustable to adjust the overall height of the support structure and is rotatably connected to the head assembly at one end. The head assembly is controllably expandable or foldable relative to the fuselage assembly.

[0008] When the head assembly is deployed on the body assembly, the overall height of the support structure is D1, and D1 satisfies: 800mm≤D1≤1100mm.

[0009] The above design allows for adjustment of the fan's working or stowed height, meeting the needs of users in different height scenarios. In the unfolded state, the center of gravity of the fan head assembly rests on the axis of the body assembly, ensuring overall stability of the fan during operation and mitigating issues of instability and wobbling, thus satisfying diverse user requirements.

[0010] In one embodiment of the first aspect, the head assembly includes a working component and a connecting component, the two ends of the connecting component being rotatably connected to the working component and the body assembly, respectively, and the rotation angle of the connecting component relative to the body assembly is α, wherein α satisfies: 180°≤α≤270°.

[0011] With the above design, when the head assembly and the body assembly are folded, they tend to be parallel, minimizing their folded thickness and further reducing storage space. When the head assembly is unfolded above the body assembly, the center of gravity of the working component falls on the axis of the body assembly, ensuring stability during fan operation.

[0012] In one embodiment of the first aspect, the fuselage assembly includes a telescopically adjustable support and a connecting bracket, the support having a first axis;

[0013] The connecting bracket has a first end connected to the support member and a second end in a direction away from the first axis. The axis of the first end coincides with the first axis, and the second end has a second axis and is rotatably connected to the connecting member. The connecting member can be controlled to rotate relative to the body assembly about the second axis.

[0014] With the above design, in the folded state, the connector abuts against the bottom surface of the second end, limiting the flipping angle of the connector and ensuring that the center of gravity of the whole machine falls on the connecting bracket, maintaining overall stability.

[0015] In one embodiment of the first aspect, the distance between the first axis and the second axis is L1, wherein L1 satisfies: 30mm≤L1≤150mm.

[0016] The above design limits the length of the connector, ensuring the setting of the connector's rotation angle and the center of gravity of the whole machine, thereby improving the overall operational stability.

[0017] In one embodiment of the first aspect, the support structure has multiple storage states, the working component has a third axis, and when the support structure is in the storage state, the head assembly is controlled to flip and fold onto the body assembly, the distance between the third axis and the second axis is L2, and L2 satisfies: 150mm≤L2≤400mm.

[0018] The above design limits the overall height of the head assembly when folded, ensuring the center of gravity of the support structure in the folded state, so that the whole machine can remain upright and stable when stored.

[0019] In one embodiment of the first aspect, when the support structure is in the retracted state, the head assembly is controlled to flip and fold over the body assembly, and the height of the support structure is D2, wherein D2 satisfies: 470mm≤D2≤770mm.

[0020] With the above design, when users are folding and storing or unfolding the machine, they only need to bend over to rotate the head assembly, without having to squat, resulting in a better user experience.

[0021] In one embodiment of the first aspect, the end of the connector connected to the second end is provided with a rotating shaft, the axis of the rotating shaft coincides with the axis of the second shaft, and the diameter of the rotating shaft is Ф, wherein Ф satisfies: 10mm≤Ф≤80mm.

[0022] The above design limits the size of the connecting bracket and further adjusts the overall center of gravity of the bracket structure.

[0023] In one embodiment of the first aspect, the bracket structure further includes a locking assembly, the locking assembly including a pressing member, one end of the connector connected to the second end having a sliding groove and a limiting groove communicating with each other, the pressing member being telescopically inserted through the sliding groove and the limiting groove, and sleeved on the rotating shaft, the pressing member being able to rotate with the rotating shaft and having an abutting part;

[0024] Wherein, when the abutting part moves to the slide groove along with the pressing member, the abutting part can rotate within the slide groove, and the pressing member rotates along with the connecting member;

[0025] When the abutting part moves to the limiting groove along with the pressing member, the limiting groove and the abutting part engage to prevent rotation, and the pressing member restricts the rotation of the connecting member.

[0026] With the above design, the limiting groove wall abuts against the abutting part, thereby preventing the pressing part from rotating arbitrarily, thus restricting the rotation of the machine head assembly and maintaining the stability of the machine head assembly in the unfolded state, without the need for an additional manual locking switch, reducing manpower and facilitating operation.

[0027] In one embodiment of the first aspect, the end of the connector connected to the second end has a notch, the second end has a snap-fit ​​section, the snap-fit ​​section snaps into the notch, one end of the rotating shaft protrudes from the notch and rotates into the snap-fit ​​section, the width of the snap-fit ​​section is L3, and L3 satisfies: 30mm≤L3≤100mm.

[0028] Through the above design, the width L3 of the snap-fit ​​section is set to match the diameter Ф of the rotating shaft, which limits the size of the connector and the connecting bracket, and facilitates the design of the center of gravity of the whole machine.

[0029] In one embodiment of the first aspect, the external width of the end of the connector connected to the second end is L4, wherein L4 satisfies: 65mm≤L4≤130mm.

[0030] Through the above design, the external width L4 of the connector is set in conjunction with L3 to further limit the size of the connector and the connecting bracket, which facilitates the design of the center of gravity of the whole machine.

[0031] In one embodiment of the first aspect, the pressing member has a pressing surface on the side facing away from the rotating shaft, and the pressing surface protrudes relative to the surface of the connecting member.

[0032] The above design exposes the pressing surface to the outside of the connector, making it more intuitive for the user to observe and easier to operate.

[0033] In one embodiment of the first aspect, the protrusion value of the pressing surface relative to the surface of the connector is L5, wherein L5 satisfies: 2mm≤L5≤15mm.

[0034] The above design allows for the selection of an appropriate protrusion height for the pressing element, facilitating the user's pressing operation.

[0035] Secondly, embodiments of this application also provide a fan, including the bracket structure described in any of the above embodiments.

[0036] The above design provides multiple states for the fan, meeting diverse work and storage needs, and ensuring the fan's center of gravity is stable, maintaining good operating condition.

[0037] Compared to related technologies, the advantages of this application are as follows: This application provides a support structure and a fan, which can realize the adjustment of the fan in multiple working and storage states. The support structure includes a head assembly and a body assembly. The body assembly can extend and retract to adjust the overall height of the support structure, and one end is rotatably connected to the head assembly. The head assembly can be controlled to unfold or fold relative to the body assembly. In this way, when storing the fan, the head assembly can be folded onto the support structure, and the body assembly can be controlled to retract, reducing the overall height and storage space. At the same time, during the operation of the fan, the head assembly is unfolded in the body assembly, and the overall height of the support structure can be adjusted between 800mm and 1100mm, with an extension and retraction adjustment range of 300mm, meeting the application needs of users in different height scenarios.

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0057] In related technologies, some circulating fans are generally around 1 meter in height and typically use a connecting pipe system for both tabletop and floor use. Their operation is complex, involves many steps, and results in a poor user experience. Furthermore, they lack a folding storage function, making them inconvenient to store in winter and taking up valuable space. Meanwhile, some circulating fans use a telescopic rod for height adjustment, but the adjustment range is limited, generally only around 150mm, limiting their applications and failing to meet the needs of users at different heights, such as those on beds, dining tables, sofas, or standing. Additionally, some fans do have a folding storage function, but these generally use a multi-joint telescopic design with the folding mechanism located on the chassis, resulting in significant wobbling when unfolded, poor product reliability, and a poor user experience.

[0058] See Figure 1 and Figure 2 As shown, to improve the above-mentioned problems, embodiments of this application provide a support structure 100 that can achieve multiple states of adjustment, including folding for storage and telescopic adjustment. It should be noted that the support structure 100 provided in this application can be applied to various vertical devices. For ease of understanding, a fan is used as a specific application scenario in this application embodiment.

[0059] Specifically, the support structure 100 includes a head assembly 110 and a body assembly 120. The head assembly 110 is the working component of the fan, and the body assembly 120 is the supporting component of the fan. The head assembly 110 and the body assembly 120 are rotatably connected, allowing the head assembly 110 to be controlled to unfold or fold relative to the body assembly 120. This enables the head assembly 110 to be unfolded and folded for storage, achieving different fan states and meeting diverse user needs.

[0060] Furthermore, the body assembly 120 has a telescopic adjustment function, which allows for telescopic adjustment of the overall height of the bracket structure 100, thereby adjusting the working height or storage height of the fan to meet the needs of users in different height scenarios.

[0061] In operation, the head unit 110 extends above the body unit 120, thus directing the fan's exhaust surface towards the user. The bracket structure 100 has, for example,... Figure 1The first working state is shown, at which point the support structure 100 reaches its maximum tensile height. Additionally, the support structure 100 also has the following characteristics: Figure 2 The second working state is shown, in which the support structure 100 reaches its maximum retracted height. In this way, by rotating the head assembly 110 above the body assembly 120, and in the unfolded state, the center of gravity of the head assembly 110 falls on the axis of the body assembly 120, ensuring the overall stability of the fan during operation and improving the problem of unstable center of gravity and easy swaying of the multi-joint folding method in related technologies.

[0062] Preferably, when the support structure 100 reaches its maximum extended height, its overall height D1 is 1100mm. When the support structure 100 reaches its maximum retracted height, its overall height D1 is 800mm. Thus, the extension / retraction adjustment range of the support structure 100 reaches 300mm, which can meet the daily user needs at different heights, such as in beds, dining tables, sofas, and while standing, thereby improving the customer experience.

[0063] Continue reading Figure 3 As shown, the head assembly 110 further includes a working component 111 and a connecting component 112. The two ends of the connecting component 112 are rotatably connected to the working component 111 and the body assembly 120, respectively. The rotation angle of the connecting component 112 relative to the body assembly 120 is α, which satisfies: 180°≤α≤270°.

[0064] Specifically, the working component 111 can be the fan head for supplying air to the user. Through its rotatable connection with the connecting component 112, after reaching the optimal working height, the working component 111 can also rotate relative to the connecting component 112 to select the optimal airflow angle, improving the user experience. The outer surface of the body assembly 120 can limit the rotation angle of the connecting component 112. When the head assembly 110 is folded onto the body assembly 120, the connecting component 112 is pressed against one side of the body assembly 120, the working component 111 is in close contact with the body assembly 120, and the head assembly 110 and body assembly 120 tend to be parallel, minimizing their folded thickness and further reducing storage space. When the head assembly 110 is unfolded above the body assembly 120, the connecting component 112 is pressed against the top side of the body assembly 120, and the center of gravity of the working component 111 falls on the axis of the body assembly 120, ensuring stability during fan operation.

[0065] Preferably, the rotation angle α of the connector 112 relative to the body assembly 120 can be 180°, 189°, 197°, 200°, 203°, 209°, 220°, 232°, 240°, 256°, 270°, etc. The specific rotation angle α can be adjusted according to design requirements to affect the maximum height of the support structure 100 in the unfolded state and the minimum height in the folded state.

[0066] In some embodiments, when the support structure 100 is in a retracted state, the head assembly 110 is controlled to flip and fold over the body assembly 120, and the height of the support structure 100 is D2, wherein D2 satisfies: 470mm≤D2≤770mm.

[0067] Specifically, the support structure 100 can have multiple storage states. In the storage state, the head assembly 110 is flipped and folded into the body assembly 120, and the height of the body assembly 120 can be adjusted according to storage needs to adapt to the corresponding storage space. When the support structure 100 is in the first storage state, the body assembly 120 reaches its maximum retracted height, and the overall height D2 of the support structure 100 is 470mm. When the support structure 100 is in the second storage state, the body assembly 120 reaches its maximum extended height, and the overall height D2 of the support structure 100 is 770mm. Thus, when the user folds and stores the device or unfolds it for operation, the user only needs to bend over to rotate the head assembly 110, without having to squat, resulting in a better user experience.

[0068] Continue reading Figure 4 As shown, in some embodiments, the fuselage assembly 120 includes a telescopically adjustable support 121 and a connecting bracket 122. The support 121 has a first axis. The connecting bracket 122 has a first end 1221 connected to the support 121 and a second end 1222 extending away from the first axis. The axis of the first end 1221 coincides with the first axis, and the second end 1222 has a second axis and is rotatably connected to a connecting member 112. The connecting member 112 is controllably rotatable relative to the fuselage assembly 120 about the second axis.

[0069] Specifically, the support member 121 includes a first sleeve 1211 and a second sleeve 1212 that fit together. The second sleeve 1212 is inserted into the first sleeve 1211 and can be extended and retracted relative to the first sleeve 1211 to adjust the overall height of the support structure 100. The top of the first sleeve 1211 is connected to the first end 1221 of the connecting bracket 122, thereby fixing the connecting bracket 122 to the support member 121. The second end 1222 of the connecting bracket 122 extends away from the first end 1221 at a certain angle to form a triangular structure. The connecting member 112 is rotatably connected to the second end 1222, so that in the unfolded state, it abuts against the top surface of the second end 1222, and in the folded state, it abuts against the bottom surface of the second end 1222, limiting the rotation angle of the connecting member 112 and ensuring that the center of gravity of the whole machine falls on the connecting bracket 122, maintaining overall stability.

[0070] In some embodiments, the distance between the first axis and the second axis is L1, where L1 satisfies: 30mm≤L1≤150mm.

[0071] Preferably, L1 can be 30mm, 46mm, 53mm, 79mm, 82mm, 88mm, 95mm, 100mm, 120mm, 150mm, etc., and can be designed according to actual needs. By limiting L1, the length of the connector 112 can be set accordingly, ensuring the rotation angle setting of the connector 112 and the center of gravity landing point of the whole machine, thereby improving the overall operational stability.

[0072] Continue reading Figure 5 As shown, in some embodiments, the working component 111 has a third axis. When the support structure 100 is in the retracted state, the head assembly 110 is controlled to flip and fold onto the body assembly 120. The distance between the third axis and the second axis is L2, and L2 satisfies: 150mm≤L2≤400mm.

[0073] Preferably, L2 can be 150mm, 160mm, 189mm, 193mm, 201mm, 236mm, 231mm, 256mm, 289mm, 301mm, 352mm, 367mm, 400mm, etc., and can be designed according to actual needs. By limiting L2, the height of the head assembly 110 after folding can be limited, ensuring the center of gravity of the support structure 100 in the folded state, so that the whole machine can still maintain vertical stability in the storage state.

[0074] Continue reading Figure 6 and Figure 7 As shown, in some embodiments, the end of the connector 112 connected to the second end 1222 is provided with a rotating shaft 1121. The axis of the rotating shaft 1121 coincides with the axis of the second axis. The diameter of the rotating shaft 1121 is Ф, and Ф satisfies: 10mm≤Ф≤80mm.

[0075] Specifically, the connector 112 has a Y-shaped structure, and the two sides of the working piece 111 are rotatably connected to the upper ends of the connector 112 to ensure the balance of the working piece 111. A pivot 1121 is provided at the lower end of the connector 112, which rotatably engages with the second end 1222 of the connecting bracket 122. Simultaneously, the size of the connecting bracket 122 is limited by the diameter Ф of the pivot 1121, further adjusting the overall center of gravity of the bracket structure 100.

[0076] Preferably, Ф can be 10mm, 15mm, 19mm, 22mm, 23mm, 24mm, 30mm, 45mm, 56mm, 72mm, 75mm, 80mm, etc., and can be designed according to actual needs. By limiting Ф, the size of the connector 112 and the connecting bracket 122 can be set accordingly to ensure the center of gravity of the whole machine.

[0077] Furthermore, the end of the connector 112 connected to the second end 1222 has a notch 1122, and the second end 1222 has a snap-fit ​​section 12221. The snap-fit ​​section 12221 snaps into the notch 1122. One end of the rotating shaft 1121 protrudes from the notch 1122 and rotates with the snap-fit ​​section 12221. The width of the snap-fit ​​section 12221 is L3, and L3 satisfies: 30mm≤L3≤100mm.

[0078] Specifically, by providing the notch 1122, the connector 112 has space to rotate relative to the connecting bracket 122. The snap-fit ​​section 12221 snaps into the notch 1122 of the connector 112, thereby resisting the upper wall of the notch 1122 by the upper and lower ends of the snap-fit ​​end, thus limiting the flipping angle of the connector 112.

[0079] Preferably, L3 can be 30mm, 330mm, 41mm, 45mm, 47mm, 52mm, 61mm, 71mm, 82mm, 93mm, 99mm, 100mm, etc., and can be designed according to actual needs. By setting L3 in conjunction with the diameter Ф of the rotating shaft 1121, the size of the connector 112 and the connecting bracket 122 is limited, which facilitates the design of the center of gravity of the whole machine.

[0080] Furthermore, the external width of the end of the connector 112 connected to the second end 1222 is L4, and L4 satisfies: 65mm≤L4≤130mm.

[0081] Understandably, the overall width L4 refers to the width of the lower end of the connector 112 along the second axis. Preferably, L4 can be 65mm, 67mm, 70mm, 72mm, 75mm, 78mm, 82mm, 93mm, 105mm, 112mm, 121mm, 130mm, etc., and can be designed according to actual needs. By limiting the size of L4, in conjunction with L3, the dimensions of the connector 112 and the connecting bracket 122 are further defined, facilitating the design of the overall machine's center of gravity.

[0082] Continue reading Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the bracket structure 100 further includes a locking assembly. The locking assembly 130 includes a pressing member 131. One end of the connector 112 connected to the second end 1222 is provided with a sliding groove 12222 and a limiting groove 12223 that are interconnected. The pressing member 131 can be telescopically inserted through the sliding groove 12222 and the limiting groove 12223 and is sleeved on the rotating shaft 1121. The pressing member 131 can rotate with the rotating shaft 1121 and is provided with an abutment portion 1311.

[0083] Specifically, the side of the pressing member 131 away from the rotating shaft 1121 is a solid pressing surface 1313, so that when an external force is applied to the pressing surface 1313, the pressing member 131 can move along the axial direction. The abutment part 1311 is provided at the end of the pressing member 131 away from the pressing surface 1313. The connecting member 112 is also provided with a through hole. The cavity structure of the through hole is adapted to the abutment part 1311, so that the abutment part 1311 enters the limiting groove 12223 through the hole during the assembly process of the pressing member 131, and then enters the sliding groove 12222 through the limiting groove 12223 during the pressing process of the pressing member 131.

[0084] For example, when the connector 112 is unfolded relative to the body assembly 120, the abutment portion 1311 is located within the limiting groove 12223. The wall of the limiting groove 12223 abuts against the abutment portion 1311, preventing the pressing member 131 from rotating arbitrarily, thereby restricting the rotation of the connector 112 and maintaining the stability of the connector 112 in the unfolded state. This eliminates the need for a separate manual locking switch, reducing manpower and simplifying operation. When it is necessary to fold the connector 112, simply press the pressing surface 1313 of the pressing member 131, causing the pressing member 131 to move inward toward the connector 112. The abutment portion 1311 disengages from the wall of the limiting groove 12223 and enters the slide groove 12222. The abutment portion 1311 can move with the connector 112 within the slide groove 12222, thereby rotating the connector 112 and folding it with the body assembly 120 for easy storage.

[0085] Furthermore, the abutting portion 1311 includes an arc-shaped surface 13111 and two first resisting surfaces 13112 distributed at both ends of the arc-shaped surface 13111. The limiting groove 12223 is provided with two second resisting surfaces 12224 opposite to each other. When the abutting portion 1311 is located in the limiting groove 12223, each second resisting surface 12224 abuts against the corresponding first resisting surface 13112.

[0086] Specifically, both the first resisting surface 13112 and the second resisting surface 12224 are planar structures, thus making the abutment portion 1311 and the limiting groove 12223 non-circular structures. When the abutment portion 1311 is located in the limiting groove 12223, the first resisting surface 13112 and the second resisting surface 12224 abut against each other, and the pressing member 131 cannot rotate within the limiting groove 12223.

[0087] Furthermore, the pressing member 131 includes a main body 1312, and an abutting portion 1311 is disposed at one end of the main body 1312 near the body assembly 120, and protrudes relative to the peripheral surface of the main body 1312 to form a flange surface. When the abutting portion 1311 is located in the slide groove 12222 and is not aligned with the limiting groove 12223, the flange surface abuts against one side wall of the slide groove 12222 to prevent the abutting portion 1311 from axially resetting into the limiting groove 12223.

[0088] Understandably, due to the arrangement of the first resisting surface 13112, the distance from the axis of the pressing member 131 to the first resisting surface 13112 is less than the distance from the axis to the arc surface. To allow the abutting part 1311 to rotate within the slide groove 12222, the slide groove 12222 needs to be set with a radius equal to the distance from the axis of the pressing member 131 to the arc surface. Therefore, the limiting groove 12223 is narrower than the slide groove 12222. When the abutting part 1311 is not fully aligned with the limiting groove 12223, the abutting part 1311 is blocked by the connecting wall of the slide groove 12222 and the limiting groove 12223, and cannot return to the limiting groove 12223. This prevents the abutting part 1311 from returning to the limiting groove 12223 in the retracted state of the connector 112, thus avoiding the need to press the pressing member 131 again to unfold the connector 112.

[0089] In some embodiments, the locking assembly 130 further includes an elastic member 132, the two ends of which are connected to the pressing member 131 and the connecting member 112, respectively.

[0090] Specifically, the elastic element 132 can be a helical compression spring, with its two ends connected to the pressing element 131 and the connecting element 112 respectively, to achieve the pressing and resetting of the pressing element 131. In its normal state, the elastic element 132 is in a stretched state, pressing the pressing element 131 outwards, so that the abutting part 1311 is located within the limiting groove 12223. During the rotation of the connecting element 112, by pressing the pressing element 131, the elastic element 132 contracts, the abutting part 1311 enters the sliding groove 12222, and the pressing element 131 rotates with the connecting element 112.

[0091] For example, when the connector 112 is in the retracted state, the elastic member 132 presses the pressing member 131 outward due to its elastic potential energy, causing the abutment portion 1311 to press against the wall of the slide groove 12222, preventing it from resetting and entering the limiting groove 12223. When the connector 112 is rotated to the unfolded state, the abutment portion 1311 is fully aligned with the limiting groove 12223, and the elastic member 132 presses the pressing member 131 outward, causing the abutment portion 1311 to enter the limiting groove 12223, and it cannot rotate under the restriction of the wall of the limiting groove 12223.

[0092] Furthermore, the pressing surface 1313 protrudes relative to the surface of the connector 112, thereby exposing the pressing surface 1313 to the outside of the connector 112, making it more intuitive for the user to observe and easier to operate.

[0093] Furthermore, the protrusion value of the pressing surface 1313 relative to the surface of the connecting piece 112 is L5, and L5 satisfies: 2mm≤L5≤15mm.

[0094] Preferably, L5 can be 2mm, 2.5mm, 3mm, 3.3mm, 4.8mm, 5mm, 6.1mm, 7.1mm, 8.2mm, 9.3mm, 9.9mm, 12mm, 13mm, 15mm, etc., and can be designed according to actual needs. By setting L5, the protrusion height of the pressing part 131 can be selected, which facilitates the user's pressing operation.
