Description

Technical Field

[0001] The present application relates to the technical field of fans, and in particular to a bracket structure and a fan. Background Art

[0002] In the related art, some fan products do not have the folding storage function, and cannot be stored in winter, which is inconvenient and takes up space. At the same time, some products are only adjusted in height through telescopic rods, and the adjustment range is small, which cannot meet the needs of users at different heights such as beds, dining tables, sofas, and standing. Summary of the invention

[0003] Based on this, it is necessary to provide a bracket structure and a fan to address the problem that the fan cannot meet the user's needs in multiple scenarios.

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

[0005] In a first aspect, an embodiment of the present application provides a support structure, including:

[0006] Head assembly;

[0007] A fuselage assembly, which can telescopically adjust the overall height of the support structure and one end of which is rotatably connected to the nose assembly, and the nose assembly can be controlled to unfold or fold relative to the fuselage assembly;

[0008] Wherein, when the nose assembly is unfolded on the fuselage assembly, the overall height of the support structure is D1, and D1 satisfies: 800mm≤D1≤1100mm.

[0009] Through the above design, the working height or storage height of the fan can be adjusted to meet the needs of users in different height scenarios. In the unfolded state, the center of gravity of the head assembly falls on the axis of the body assembly, ensuring the overall stability of the fan during operation, improving the problem of unstable center of gravity and easy shaking, and meeting the diverse needs of users.

[0010] In one of the embodiments of the first aspect, the head assembly includes a working piece and a connecting piece, and both ends of the connecting piece are rotatably connected to the working piece and the fuselage assembly respectively. The rotation angle of the connecting piece relative to the fuselage assembly is α, and α satisfies: 180°≤α≤270°.

[0011] With the above design, when the head assembly and the body assembly are folded, the head assembly and the body assembly tend to be parallel, and the folded thickness of the two reaches the minimum, further reducing the storage space. When the head assembly is unfolded above the body assembly, the center of gravity of the operating part falls on the axis of the body assembly, ensuring the stability of the fan during operation.

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

[0013] The connecting bracket has a first end connected to the support member and a second end facing away from the first axis. The axis of the first end coincides with the first axis. 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 fuselage assembly about the second axis.

[0014] Through the above design, in the folded state, the connecting member abuts against the bottom surface of the second end, limiting the flipping angle of the connecting member and ensuring that the center of gravity of the entire machine falls on the connecting bracket to maintain overall stability.

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

[0016] Through the above design, the length of the connecting member is limited, the rotation angle setting of the connecting member and the center of gravity of the whole machine are guaranteed, and the overall operation stability performance is improved.

[0017] In one of the embodiments of the first aspect, the support structure has multiple storage states, and the working piece has a third axis. 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] Through the above design, the height of the whole machine after the head assembly is folded is limited, and the center of gravity of the support structure in the folded state is guaranteed, so that the whole machine can still remain upright and stable in the storage state.

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

[0020] Through the above design, when the user is folding or unfolding the machine, the user only needs to bend over to rotate the head assembly without having to operate in a squatting position, which provides a better operating experience.

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

[0022] Through the above design, the size of the connecting bracket is limited, and the overall center of gravity of the bracket structure is further adjusted.

[0023] In one embodiment of the first aspect, the support structure further includes a locking assembly, the locking assembly includes a pressing member, one end of the connecting member connected to the second end is provided with a sliding groove and a limiting groove that are interconnected, the pressing member can be telescopically inserted into the sliding groove and the limiting groove, and is sleeved on the rotating shaft, the pressing member can rotate with the rotating shaft and is provided with an abutment portion;

[0024] Wherein, when the abutting portion follows the pressing member to move to the slide groove, the abutting portion can rotate in the slide groove, and the pressing member follows the rotation of the operating portion;

[0025] When the abutting portion follows the pressing member to move to the limiting groove, the limiting groove and the abutting portion are engaged in a rotation-stopping manner, and the pressing member limits the rotation of the working portion.

[0026] Through the above design, the wall of the limit groove contacts the abutment portion, so that the pressing part cannot rotate arbitrarily, thereby limiting the rotation of the head assembly and maintaining the stability of the head assembly in the unfolded state without the need to set up a manual locking switch, thereby reducing manpower and facilitating operation.

[0027] In one of the embodiments of the first aspect, a notch is provided at one end of the connecting member connected to the second end, and a snap-fit ​​section is provided at the second end, the snap-fit ​​section is snap-fitted with the notch, one end of the rotating shaft protrudes from the notch and rotatably cooperates with the snap-fit ​​section, and 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 clamping section is matched with the diameter Φ of the rotating shaft to limit the size of the connecting member and the connecting bracket, which is convenient for the design of the center of gravity of the whole machine.

[0029] In one embodiment of the first aspect, an outer width of an end of the connecting member connected to the second end is L4, and L4 satisfies: 65mm≤L4≤130mm.

[0030] Through the above design, the appearance width L4 of the connecting piece is matched with L3 to further limit the size of the connecting piece and the connecting bracket, which is convenient for the design of the center of gravity of the whole machine.

[0031] In one of the embodiments of the first aspect, a pressing surface is provided on a side of the pressing member facing away from the rotating shaft, and the pressing surface is protruding relative to a surface of the connecting member.

[0032] Through the above design, the pressing surface is exposed to the outside of the connecting piece, which is more intuitive for users to observe and easier to operate.

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

[0034] Through the above design, a suitable protruding height of the pressing member is selected to facilitate the pressing operation of the user.

[0035] In a second aspect, an embodiment of the present application further provides a fan, comprising the support structure described in any of the above embodiments.

[0036] Through the above design, a variety of state designs of the fan are provided to meet diverse working and storage needs, and ensure that the center of gravity of the fan is stable and maintains a good working state.

[0037] Compared with the related art, the beneficial effects of the present application are as follows: the present application provides a support structure and a fan, which can realize the adjustment of various working states and storage states of the fan. The support structure includes a head assembly and a body assembly. The body assembly can telescopically adjust the overall height of the support structure and one end is rotatably connected to the head assembly, and the head assembly can be controlled to unfold or fold relative to the body assembly.

[0057] In the related art, the height of some circulation fans is generally around 1m, and they are usually used on both the table and the ground by splicing tubes. The operation method is complicated, there are many operation steps, the user experience is not good, and they do not have a folding storage function. In winter, the product cannot be stored, which is inconvenient and takes up space. At the same time, some circulation fans use a telescopic rod height adjustment method, but the height adjustment range is small, generally only about 150mm, the product has few uses, and cannot cover the needs of users at different heights such as beds, dining tables, sofas, and standing. In addition, some fans have a folding storage function, but generally use a multi-joint telescopic solution, and the folding mechanism is set on the chassis, which causes a lot of shaking when the product is unfolded and used, poor product quality reliability, and poor user experience.

[0058] See also Figure 1 and Figure 2 As shown, in order to improve the above problems, the embodiment of the present application provides a support structure 100, which can realize folding storage and telescopic adjustment in multiple states. It should be noted that the support structure 100 provided by the present application can be applied to various vertical devices. For ease of understanding, in the embodiment of the present application, a fan is used as a specific application scenario for explanation.

[0059] Specifically, the support structure 100 includes a head assembly 110 and a body assembly 120. The head assembly 110 is a working part of the fan, and the body assembly 120 is a supporting part of the fan. The head assembly 110 and the body assembly 120 are rotatably connected, so that the head assembly 110 can be controlled to unfold or fold relative to the body assembly 120, thereby realizing the unfolding operation and folding storage of the head assembly 110, realizing different states of the fan, and meeting the diverse needs of users.

[0060] Furthermore, the body assembly 120 has a telescopic adjustment function, so that the overall height of the bracket structure 100 can be telescopically adjusted, so that the working height or storage height of the fan can be adjusted to meet the needs of users in different height scenarios.

[0061] In the working state, the head assembly 110 is unfolded above the body assembly 120, so that the air outlet of the fan faces the user. Figure 1In the first working state shown in FIG. 1 , the support structure 100 reaches the maximum stretched height. Figure 2 In the second working state shown, the support structure 100 reaches the 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, the overall stability of the fan during operation is ensured, and the problem of unstable center of gravity and easy shaking in the multi-joint folding method of the related art is improved.

[0062] Preferably, when the support structure 100 reaches the maximum extension height, the overall height D1 of the support structure 100 is 1100 mm. When the support structure 100 reaches the maximum contraction height, the overall height D1 of the support structure 100 is 800 mm. In this way, the telescopic adjustment range of the support structure 100 reaches 300 mm, which can meet the daily needs of users at different heights such as beds, dining tables, sofas, and standing, and improve customer experience.

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

[0064] Specifically, the operating member 111 can be the fan head of the fan to supply air to the user. Through the rotational connection with the connecting member 112, after reaching the optimal operating height, the operating member 111 can also rotate relative to the connecting member 112 to select the optimal air outlet angle to improve the user experience. The outer surface of the fuselage assembly 120 can limit the rotation angle of the connecting member 112. When the head assembly 110 is folded on the fuselage assembly 120, the connecting member 112 is pressed against one side of the fuselage assembly 120, the operating member 111 fits with the fuselage assembly 120, and the head assembly 110 and the fuselage assembly 120 tend to be parallel. The folded thickness of the two reaches the minimum, further reducing the storage space. When the head assembly 110 is unfolded above the fuselage assembly 120, the connecting member 112 is pressed against the top side of the fuselage assembly 120, and the center of gravity of the operating member 111 falls on the axis of the fuselage assembly 120, ensuring the stability of the fan during operation.

[0065] Preferably, the rotation angle α of the connecting member 112 relative to the fuselage assembly 120 can be 180°, 189°, 197°, 200°, 203°, 209°, 220°, 232°, 240°, 256°, 270°, etc., and can be rotated according to design requirements to affect the maximum height of the unfolded state and the minimum height of the folded state of the support structure 100 through the size of the rotation angle α.

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

[0067] Specifically, the support structure 100 can have a variety of storage states. When in the storage state, the head assembly 110 is flipped and folded on the body assembly 120, and then the height of the body assembly 120 is adjusted according to the storage requirements to adapt to the corresponding storage space. When the support structure 100 is in the first storage state, the body assembly 120 reaches the 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 the maximum stretched height, and the overall height D2 of the support structure 100 is 770mm. In this way, when the user is folding, storing or unfolding the operation, the user only needs to bend over to rotate the head assembly 110, without having to operate in a squatting position, which provides a better operating experience.

[0068] Continue reading Figure 4 As shown, in some embodiments, the fuselage assembly 120 includes a telescopically adjustable support member 121 and a connecting bracket 122, wherein the support member 121 has a first axis. The connecting bracket 122 has a first end 1221 connected to the support member 121 and a second end 1222 in a direction away from the first axis, wherein 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 the connecting member 112, and the connecting member 112 can be controlled to rotate 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 are sleeved together. The second sleeve 1212 is inserted into the first sleeve 1211 and can be adjusted 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, so that the connecting bracket 122 is fixed to the support member 121. The second end 1222 of the connecting bracket 122 extends away from the first end 1221 at a certain inclination 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 flip angle of the connecting member 112, and ensuring that the center of gravity of the whole machine falls on the connecting bracket 122 to maintain overall stability.

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

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

[0072] Continue reading Figure 5 As shown, in some embodiments, the working piece 111 has a third axis. When the support structure 100 is in the storage state, the head assembly 110 is controlled to flip and fold on 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 specifically designed according to actual needs. By limiting L2, the height of the whole machine after the head assembly 110 is folded can be limited, and the center of gravity of the support structure 100 in the folded state can be guaranteed, so that the whole machine can still remain upright and stable in the storage state.

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

[0075] Specifically, the connecting member 112 is in a Y-shaped structure, and the two sides of the working member 111 are rotatably connected to the two ends of the upper side of the connecting member 112 to ensure the balance of the working member 111. A rotating shaft 1121 is provided at one end of the connecting member 112 at the bottom, so as to rotatably cooperate with the second end 1222 of the connecting bracket 122 through the rotating shaft 1121. At the same time, by setting the size of the diameter Φ of the rotating shaft 1121, the size of the connecting bracket 122 is limited, and the overall center of gravity of the bracket structure 100 is further adjusted.

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

[0077] Furthermore, a notch portion 1122 is provided at one end of the connecting member 112 connected to the second end 1222, and a snap-fit ​​section 12221 is provided at the second end 1222. The snap-fit ​​section 12221 is snap-fitted with the notch portion 1122, and one end of the rotating shaft 1121 protrudes from the notch portion 1122 and rotatably cooperates 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 setting the notch portion 1122, the connecting member 112 obtains space to rotate relative to the connecting bracket 122, and the clamping section 12221 is clamped in the notch portion 1122 of the connecting member 112, so that the upper and lower ends of the clamping end resist the upper wall of the notch portion 1122, thereby limiting the flipping angle of the connecting member 112.

[0079] Preferably, L3 can be 30mm, 330mm, 41mm, 45mm, 47mm, 52mm, 61mm, 71mm, 82mm, 93mm, 99mm, 100mm, etc., and can be specifically designed according to actual needs. By setting L3, it is matched with the diameter Φ of the rotating shaft 1121 to limit the size of the connecting member 112 and the connecting bracket 122, which is convenient for the design of the center of gravity of the whole machine.

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

[0081] It can be understood that the appearance width L4 is the overall width dimension of the lower end of the connector 112 in the second axial direction. Preferably, L4 can be 65mm, 67mm, 70mm, 72mm, 75mm, 78mm, 82mm, 93mm, 105mm, 112mm, 121mm, 130mm, etc., and can be specifically designed according to actual needs. Through the limitation of L4, in combination with L3, the size of the connector 112 and the connecting bracket 122 is further limited, which is convenient for the design of the center of gravity of the whole machine.

[0082] Continue reading Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments, the support structure 100 also includes a locking assembly, the locking assembly 130 includes a pressing piece 131, and one end of the connecting piece 112 connected to the second end 1222 is provided with a sliding groove 12222 and a limiting groove 12223 that are interconnected. The pressing piece 131 can be telescopically inserted into the sliding groove 12222 and the limiting groove 12223, and is sleeved on the rotating shaft 1121. The pressing piece 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 acts on the pressing surface 1313, the pressing member 131 can move along the axial direction. The abutment portion 1311 is provided at one end of the pressing member 131 away from the pressing surface 1313, and the connecting member 112 is further provided with a through hole, the cavity structure of the through hole is adapted to the abutment portion 1311, so that the abutment portion 1311 enters the limiting groove 12223 through the hole during the assembly process of the pressing member 131, and then enters the slide groove 12222 through the limiting groove 12223 during the pressing process of the pressing member 131.

[0084] Exemplarily, when the connecting member 112 is unfolded relative to the fuselage assembly 120, the abutting portion 1311 is located in the limiting groove 12223. The wall surface of the limiting groove 12223 abuts against the abutting portion 1311, so that the pressing member 131 cannot rotate arbitrarily, thereby limiting the rotation of the connecting member 112 and maintaining the stability of the connecting member 112 in the unfolded state without the need to set up an additional manual locking switch, thereby reducing manpower and facilitating operation. When the connecting member 112 needs to be folded, it is only necessary to press the pressing surface 1313 of the pressing member 131 to move the pressing member 131 toward the inner side of the connecting member 112, and the abutting portion 1311 is separated from the wall surface of the limiting groove 12223 and enters the interior of the slide groove 12222. The abutting portion 1311 can move with the connecting member 112 in the slide groove 12222, thereby rotating the connecting member 112, so that the connecting member 112 and the fuselage assembly 120 are folded for easy storage.

[0085] Further, the abutting portion 1311 includes an arcuate surface 13111 and two first resisting surfaces 13112 distributed at both ends of the arcuate 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 respectively.

[0086] Specifically, the first resisting surface 13112 and the second resisting surface 12224 are both planar structures, so that the abutting portion 1311 and the limiting groove 12223 are not regular circular structures. When the abutting portion 1311 is located in the limiting groove 12223, the first resisting surface 13112 and the second resisting surface 12224 are in conflict, and the pressing member 131 cannot rotate in the limiting groove 12223.

[0087] Furthermore, the pressing member 131 includes a main body 1312, and the abutting portion 1311 is disposed at one end of the main body 1312 close to the fuselage 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 a side wall of the slide groove 12222 to limit the abutting portion 1311 from being reset axially into the limiting groove 12223.

[0088] It is understandable that due to the setting of the first resisting surface 13112, the distance between the axis of the pressing member 131 and the first resisting surface 13112 is smaller than the distance between the axis and the arc surface, and in order to allow the abutting portion 1311 to rotate in the slide groove 12222, the slide groove 12222 needs to be set with the distance between the axis of the pressing member 131 and the arc surface as the radius. Therefore, the limiting groove 12223 is narrowed relative to the slide groove 12222, and when the abutting portion 1311 is not completely aligned with the limiting groove 12223, the abutting portion 1311 is blocked by the connecting wall of the slide groove 12222 and the limiting groove 12223 and cannot be reset to the limiting groove 12223, thereby avoiding the abutting portion 1311 from being reset to the limiting groove 12223 in the storage state of the connecting member 112, and the pressing member 131 needs to be pressed again to unfold the connecting member 112.

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

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

[0091] For example, when the connecting member 112 is in the storage state, the elastic member 132 presses the pressing member 131 outward due to the elastic potential energy, so that the abutting portion 1311 is pressed against the wall of the sliding groove 12222 and cannot be reset to enter the limiting groove 12223. When the connecting member 112 is rotated to the unfolded state, the abutting portion 1311 is completely aligned with the limiting groove 12223, and the elastic member 132 presses the pressing member 131 outward, so that the abutting portion 1311 enters the limiting groove 12223 and 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 connecting member 112, so that the pressing surface 1313 is exposed to the outside of the connecting member 112, which is more intuitive for users to observe and convenient for operation.

[0093] Furthermore, the protrusion value of the pressing surface 1313 relative to the surface of the connecting member 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 specifically designed according to actual needs. By setting L5, the protruding height of the pressing member 131 is selected to facilitate the user's pressing operation.
