Description

Technical Field

[0001] This application relates to the field of vehicle-mounted mobile phone holder technology, and in particular to a folding holder. Background Technology

[0002] With the development of communication technology, mobile phones have become indispensable communication tools in users' daily lives and work. For safety reasons while driving, and also for the convenience of using mobile devices such as phones in the car (e.g., using navigation while driving), car phone holders and related products are highly popular. However, due to their structural design, car phone holders can only be used to fix phones, resulting in limited functionality and failing to meet the growing needs of users. Furthermore, car phone holders are generally bulky and occupy a significant amount of space. Utility Model Content

[0003] This application provides a folding bracket that can solve the problems of limited functionality and large space occupation of in-vehicle mobile phone holders in related technologies due to their structural design.

[0004] This application provides a folding bracket; the folding bracket includes a base, a connecting structure, a fixing component, and an aromatherapy storage part. The base is used to connect with an external carrier. The connecting structure is rotatably connected to the base and can switch between a folded, non-expanded state and an angled, unfolded state relative to the base. The connecting structure has a clearance space. When the connecting structure is in the folded, non-expanded state relative to the base, a portion of the base is located within the clearance space. The fixing component is used to position the product to be fixed. The fixing component is rotatably connected to the connecting structure and can switch between a folded, non-expanded state and an angled, unfolded state relative to the connecting structure. The aromatherapy storage part is used to store aromatherapy products and is disposed on at least one of the base, the connecting structure, and the fixing component.

[0005] Based on the embodiments of this application, the folding bracket is designed with an aromatherapy storage section for storing aromatherapy products. This allows the folding bracket to not only secure the product but also provide a comfortable atmosphere for the user, offering multiple functions to meet user needs. The connecting structure is rotatably connected to the base and the fixing component. The fixing component can rotate relative to the connecting structure to a folded, non-expanded state, and the connecting structure can also rotate relative to the base to a folded, non-expanded state, thus reducing the space occupancy rate of the folding bracket when idle. Furthermore, by designing clearance space on the connecting structure, when the connecting structure rotates relative to the base to a folded, non-expanded state, part of the base is located within the clearance space. This allows the base to make reasonable use of the clearance space, further effectively reducing the space occupancy rate of the folding bracket when idle. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Please refer to Figures 1-4 As shown, this application proposes a folding bracket 1 with a compact component arrangement, which can effectively reduce the space occupancy rate of the folding bracket 1 when it is idle.

[0025] The folding bracket 1 includes a base 10, a connecting structure 20, a fixing component 30, and an aromatherapy storage section 40. The base 10 is used to connect to an external carrier. The connecting structure 20 is rotatably connected to the base 10 and can switch between a folded, non-expanded state and an angled, unfolded state relative to the base 10. The connecting structure 20 has clearance space; when the connecting structure 20 is in the folded, non-expanded state relative to the base 10, a portion of the base 10 is located within the clearance space. The fixing component 30 is used to position the product 2 to be fixed. The fixing component 30 is rotatably connected to the connecting structure 20 and can switch between a folded, non-expanded state and an angled, unfolded state relative to the connecting structure 20. The aromatherapy storage section 40 is used to store aromatherapy products 17 and is located on at least one of the base 10, the connecting structure 20, and the fixing component 30.

[0026] The following combination Figures 1-15 The specific structure of the folding bracket 1 will be described in detail.

[0027] like Figures 1-4 As shown, the folding bracket 1 includes a base 10, a connecting structure 20, a fixing component 30, and an aromatherapy storage section 40.

[0028] The base 10 serves as the base of the folding bracket 1. The specific material of the base 10 is not limited here. Designers can make reasonable choices according to actual needs. For example, the material of the base 10 can be, but is not limited to, plastic or rubber. The specific structure of the base 10 will be described in detail below.

[0029] The base 10 is used to connect to an external carrier; the external carrier may be, but is not limited to, the vehicle's front driver's cabin platform, the vehicle's windshield, a desktop, a wall, etc. The specific connection method between the base 10 and the external carrier will be described in detail below.

[0030] The connecting structure 20 serves as the connecting mechanism for the folding bracket 1, and is used to connect the base 10 and the fixing component 30. The specific material of the connecting structure 20 is not limited here, and the designer can make a reasonable choice according to actual needs. For example, the material of the connecting structure 20 can be metal.

[0031] The connecting structure 20 is rotatably connected to the base 10. The specific rotatable connection method between the connecting structure 20 and the base 10 is not limited here. Designers can make reasonable designs according to actual needs. For example, the connecting structure 20 can be rotatably connected to the base 10 through a rotating shaft, but is not limited to that of the base 10.

[0032] The connecting structure 20 can switch between a folded, non-expanded state and an angled, unfolded state relative to the base 10. The connecting structure 20 has both a non-expanded and unfolded state. When the product 2 to be fixed is not needed to be supported by the folding bracket 1, the connecting structure 20 can rotate relative to the base 10 to fold into the non-expanded state, reducing the space occupied by the folding bracket 1. When the product 2 to be fixed needs to be supported by the folding bracket 1, the connecting structure 20 can rotate relative to the base 10 to an angled position to be unfolded, thus effectively supporting the product 2 to be fixed. It should be noted that the switching between the non-expanded and unfolded states of the connecting structure 20 can be achieved manually (e.g., by the user directly applying external force to the connecting structure 20) or electrically (e.g., by a motor, gears, etc., driving the connecting structure 20).

[0033] The connecting structure 20 has a clearance space; when the connecting structure 20 includes a connecting plate, the clearance space may be a clearance groove formed on the connecting plate; when the connecting structure 20 is a connecting ring as described below, the annular hole of the connecting ring may be used to form the clearance space.

[0034] When the connecting structure 20 is in a non-expanded state relative to the base 10, part of the base 10 is located in the clearance space. In this way, the base 10 can make reasonable use of the clearance space to further reduce the space occupancy rate of the folding bracket 1 when it is idle.

[0035] like Figures 1-4 As shown, the fixing component 30 serves as the positioning structure of the folding bracket 1, and can, but is not limited to, positioning the product 2 to be fixed by clamping, negative pressure adsorption, or magnetic adsorption. The product 2 to be fixed can, but is not limited to, objects with magnets such as mobile phones, smartwatches, and smart bracelets. The specific structure of the fixing component 30 will be described in detail below.

[0036] The fixing component 30 is rotatably connected to the connecting structure 20. The specific rotatable connection method between the fixing component 30 and the connecting structure 20 is not limited here. Designers can make reasonable designs according to actual needs. For example, the fixing component 30 can be rotatably connected to the connecting structure 20 through a rotating shaft, but is not limited to that of the fixing component 30.

[0037] The fixing component 30 can switch between a folded, non-expanded state and an angled, unfolded state relative to the connecting structure 20. The fixing component 30 has both a non-expanded and an unfolded state. When the product 2 to be fixed is not needed to be supported by the folding bracket 1, the fixing component 30 can rotate relative to the connecting structure 20 to fold into the non-expanded state, reducing the space occupied by the folding bracket 1. When the product 2 to be fixed needs to be supported by the folding bracket 1, the fixing component 30 can rotate relative to the connecting structure 20 to an angled position to be in the unfolded state, thus effectively supporting the product 2 to be fixed. It should be noted that the switching between the non-expanded and unfolded states of the fixing component 30 can be achieved manually (e.g., by the user directly applying external force to the fixing component 30) or electrically (e.g., by a motor, gears, etc., driving the fixing component 30).

[0038] The aromatherapy storage section 40 serves as a storage structure for the folding bracket 1 and is used to store the aromatherapy diffuser 17. It can be understood that the aromatherapy storage section 40 can be a virtual structure such as a space for storing the aromatherapy diffuser 17, or it can be a physical structure such as a box for storing the aromatherapy diffuser 17. The specific form of the aromatherapy storage section 40 will be described in detail below.

[0039] The aromatherapy storage section 40 is disposed on at least one of the base 10, the connecting structure 20, and the fixing component 30. For example, the aromatherapy storage section 40 may be disposed only on the base 10, or only on the connecting structure 20, or only on the fixing component 30; or, for another example, the aromatherapy storage section 40 may be disposed on the base 10 and the connecting structure 20, or on the base 10 and the fixing component 30, or on the connecting structure 20 and the fixing component 30; or, for yet another example, the aromatherapy 17 connecting section may also be disposed on the base 10, the connecting structure 20, and the fixing component 30.

[0040] Based on the folding bracket 1 in this embodiment, by designing an aromatherapy storage section 40 for storing aromatherapy 17, the folding bracket 1 can not only fix the product 2 to be fixed, but also provide a comfortable atmosphere for the user, offering multiple functions to meet the user's needs. By designing a connecting structure 20 that is rotatably connected to the base 10 and the fixing component 30, the fixing component 30 can be rotated to a folded, non-expanded state relative to the connecting structure 20, and the connecting structure 20 can also be rotated to a folded, non-expanded state relative to the base 10, thus reducing the space occupancy rate of the folding bracket 1 when it is idle. By designing an avoidance space on the connecting structure 20, when the connecting structure 20 is rotated to a folded, non-expanded state relative to the base 10, part of the base 10 is located within the avoidance space, thus the base 10 can make reasonable use of the avoidance space, thereby further effectively reducing the space occupancy rate of the folding bracket 1 when it is idle.

[0041] like Figure 1 , Figures 5-7 As shown, the base 10 has a bottom surface 111a facing an external carrier and a top surface 113a opposite to the bottom surface 111a; the aromatherapy storage part 40 is located on the side of the top surface 113a of the base 10; the connecting structure 20 includes a connecting ring rotatably connected to the top surface 113a, and the annular hole of the connecting ring is used to form a clearance space. When the connecting ring is in a folded, non-expanded state relative to the base 10, at least a portion of the aromatherapy storage part 40 is located within the annular hole of the connecting ring. In this way, the aromatherapy storage part 40 can make reasonable use of the annular hole area of ​​the connecting ring, so as to further effectively reduce the space occupancy rate of the folding bracket 1 when it is in an idle state.

[0042] It is understood that the folding bracket 1 may include a cover 412 covering one side of the storage cavity of the aromatherapy storage section 40. The cover 412 is movably or detachably connected to at least one of the base 10, the connecting structure 20 and the fixing component 30, so as to facilitate the replacement of the aromatherapy 17.

[0043] like Figure 7As shown, when the aromatherapy storage section 40 is a physical structure such as a box for storing aromatherapy 17, the aromatherapy storage section 40 includes an aromatherapy storage box 41, which includes a bottom shell 411 and a lid 412. The bottom shell 411 is disposed on the top surface 113a; the lid 412 is movably connected to or detachably connected to the bottom shell 411 to jointly form a storage cavity for storing aromatherapy 17, and the lid 412 has at least one aromatherapy hole 41a. The specific installation method between the bottom shell 411 and the base 10 is not limited here, and designers can make reasonable designs according to actual needs. For example, the bottom shell 411 can be detachably connected to the base 10 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the bottom shell 411 can be non-detachably connected to the base 10 by adhesive bonding, injection molding, or 3D printing. The specific movable or detachable connection method between the cover 412 and the bottom shell 411 is not limited here, and designers can make reasonable designs according to actual needs. For example, the cover 412 can rotate or slide relative to the bottom shell 411. For example, the cover 412 can be detachably connected to the bottom shell 411 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. By designing the aromatherapy storage section 40 as an aromatherapy storage box 41, and designing the aromatherapy storage box 41 as a bottom shell 411 and a lid 412, the bottom shell 411 and the lid 412 together form a storage cavity, in which the aromatherapy 17 is stored, providing a comfortable atmosphere for the user.

[0044] like Figure 7 As shown, at least one aroma diffuser hole 41a includes multiple aroma diffuser holes 41a. The cover 412 includes a substrate 412a and a sidewall structure 412b connecting the edge of the substrate 412a. The multiple aroma diffuser holes 41a are arranged in a ring around the connection between the substrate 412a and the sidewall structure 412b. By designing multiple aroma diffuser holes 41a arranged in a ring around the connection between the substrate 412a and the sidewall structure 412b, the fragrance emitted by the aroma diffuser 17 can diffuse in all directions through the aroma diffuser holes 41a, providing a comfortable atmosphere for the user.

[0045] More specifically, the bottom shell 411 includes a bottom plate 411a, an outer edge 411b, and an inner edge 411c. The bottom plate 411a is annular, the outer edge 411b is connected to the outer edge of the bottom plate 411a, and the inner edge 411c is connected to the inner edge of the bottom plate 411a. The bottom plate 411a, the outer edge 411b, the inner edge 411c, the base plate 412a, and the side wall structure 412b together form a storage cavity. By designing the bottom plate 411a as annular, the part of the second sub-shell 113 (described below) that protrudes away from the bottom surface 111a can be stored in the annular hole of the bottom plate 411a, making the aromatherapy storage box 41 and the base 10 more compact in structure, and further reducing the overall space occupancy of the folding bracket 1.

[0046] Of course, in other embodiments, the number of aroma holes 41a can also be one, in which case the one aroma hole 41a can be annular.

[0047] like Figure 5 , Figure 6 , Figures 8-10 As shown, the base 10 includes a first housing 11, a drive bracket 12, a movable member 13, and a suction cup structure 14; the first housing 11 has the aforementioned bottom surface 111a and the aforementioned top surface 113a; the drive bracket 12 is disposed on the first housing 11 and can rotate relative to the first housing 11, and the drive bracket 12 has an inclined surface 124c; the movable member 13 is disposed on the drive bracket 12 corresponding to the inclined surface 124c; the suction cup structure 14 is connected to the movable member 13. The drive bracket 12 is configured to rotate in the forward direction relative to the first housing 11 under force to push the movable member 13, causing the movable member 13 to move from the highest side of the inclined plane 124c to the lowest side of the inclined plane 124c, thereby causing the movable member 13 to drive the suction cup structure 14 toward the external carrier to a suction state that is in contact with the external carrier; the drive bracket 12 is also configured to rotate in the reverse direction relative to the first housing 11 under force to push the movable member 13, causing the movable member 13 to move from the lowest side of the inclined plane 124c to the highest side of the inclined plane 124c, thereby causing the movable member 13 to drive the suction cup structure 14 toward the external carrier to a non-suction state that is detached from the external carrier.

[0048] The first housing 11 serves as the base shell of the base 10. The specific material of the first housing 11 is not limited; designers can choose a suitable material based on actual needs. For example, the material of the first housing 11 can be, but is not limited to, plastic or rubber. The specific structure of the first housing 11 will be described in detail below.

[0049] The drive bracket 12, acting as the driving component of the base 10, rotates relative to the first housing 11, causing the inclined surface 124c to push against the movable component 13, thereby driving the movable component 13 to move the suction cup structure 14. The specific material of the drive bracket 12 is not limited here; designers can choose a suitable material based on actual needs. For example, the material of the drive bracket 12 can be, but is not limited to, plastic or rubber. The specific structure of the drive bracket 12 will be described in detail below.

[0050] The movable component 13 serves as the power transmission component of the base 10, and is used to convert the rotational motion of the drive bracket 12 relative to the first housing 11 into a movable component 13 that can be either a rod-shaped structure or a block-shaped structure.

[0051] The suction cup structure 14 serves as a fixing component of the base 10, used to connect to an external carrier via air pressure adsorption. The suction cup structure 14 is connected to the movable component 13. Under the action of the movable component 13, the suction cup structure 14 can move towards the external carrier to a state of adsorption, and under the action of the movable component 13, it can also move away from the external carrier to a non-adsorption state, detached from the external carrier. The specific structure of the suction cup structure 14 will be described in detail below.

[0052] By designing a first housing 11, a drive bracket 12, a movable component 13, and a suction cup structure 14, the first housing 11, the drive bracket 12, the movable component 13, and the suction cup structure 14 cooperate with each other. Under the action of an external force, the drive bracket 12 rotates in the forward direction relative to the first housing 11. The rotation of the drive bracket 12 causes the inclined surface 124c to push against the movable component 13. Under the pushing action of the inclined surface 124c, the movable component 13 moves from the highest side of the inclined surface 124c to the lowest side of the inclined surface 124c. The suction cup structure 14, under the action of the movable component 13, moves towards the external carrier to a state of suction to the external carrier. At this time, the folding bracket 1 and the external carrier can be connected. The relative positions of the carriers are fixed to ensure that the folding bracket 1 effectively supports the product 2 to be fixed. Conversely, the drive bracket 12 rotates in the opposite direction to the first housing 11 under the action of external force. The rotation of the drive bracket 12 causes the inclined surface 124c to push against the movable part 13. Under the pushing action of the inclined surface 124c, the movable part 13 moves from the lowest side of the inclined surface 124c to the highest side of the inclined surface 124c. The suction cup structure 14 moves away from the external carrier under the action of the movable part 13 to a non-suction state detached from the external carrier. At this time, the relative position between the folding bracket 1 and the external carrier can be changed, and the folding bracket 1 can be stored.

[0053] Specifically, such as Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, the first housing 11 includes a first sub-shell 111 having a bottom surface 111a, a second sub-shell 113 having a top surface 113a, and a connecting shell 112 located between the first sub-shell 111 and the second sub-shell 113. The first sub-shell 111 is fixedly connected to the connecting shell 112, and the second sub-shell 113 is fixedly connected to the connecting shell 112. The connecting shell 112 has an annular structure. The drive bracket 12 includes an inner wall 121, an outer wall 122, and a connecting wall 123. The inner wall 121 is located inside the annular hole of the connecting shell 112, the outer wall 122 is arranged around the periphery of the connecting shell 112, and the connecting wall 123 is located between the first sub-shell 111 and the connecting shell 112. One side of the connecting wall 123 is connected to the inner wall 121, and the other side of the connecting wall 123 is connected to the outer wall 122.

[0054] The specific fixing connection method between the connecting shell 112 and the first sub-shell 111 is not limited here, and designers can design it reasonably according to actual needs. For example, the connecting shell 112 can be detachably connected to the first sub-shell 111 by at least one of the following methods: screw connection, snap connection, or plug connection. The specific fixing connection method between the second sub-shell 113 and the connecting shell 112 is not limited here, and designers can design it reasonably according to actual needs. For example, the second sub-shell 113 can be detachably connected to the connecting shell 112 by at least one of the following methods: screw connection, snap connection, or plug connection.

[0055] The inner enclosure 121, outer enclosure 122, and connecting wall 123 can be either separate or integrated. For example, when the inner enclosure 121, outer enclosure 122, and connecting wall 123 are separate, they can be detachably connected to each other by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, when the inner enclosure 121, outer enclosure 122, and connecting wall 123 are integrated, they can be formed into an integrated structure by injection molding or 3D printing, but are not limited to this method.

[0056] By designing the first housing 11 to include a first sub-housing 111, a second sub-housing 113, and a connecting housing 112, and designing the drive bracket 12 to include an inner wall 121, an outer wall 122, and a connecting wall 123, and designing the connecting housing 112 to be a circular structure, the first housing 11 and the drive bracket 12 are arranged more compactly in space, which can effectively reduce the volume of the base 10, thereby reducing the overall volume of the folding bracket 1.

[0057] like Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, the area of ​​the second sub-shell 113 corresponding to the annular hole of the connecting shell 112 protrudes away from the bottom surface 111a to form a movement space 113b; the drive bracket 12 also includes a drive enclosure 124, which is located in the movement space 113b and connected to the inner enclosure 121. The inner surface of the drive enclosure 124 forms a first flange 124a and a second flange 124b that protrude toward the hole axis of the annular hole of the connecting shell 112. The first flange 124a extends along a direction parallel to the hole axis of the annular hole of the connecting shell 112, and the second flange 124b extends around the hole axis of the annular hole of the connecting shell 112, and the second flange 124b has the aforementioned inclined surface 124c; the movable member 13 is located in the space enclosed by the inner surface of the drive enclosure 124, and one end of the movable member 13 abuts against the first flange 124a, and the other end of the movable member 13 rests on the inclined surface 124c.

[0058] The drive enclosure 124 and the inner enclosure 121 can be either separate or integrated. For example, when the drive enclosure 124 and the inner enclosure 121 are separate, they can be detachably connected by at least one of screwing, snap-fitting, or plugging. Alternatively, when the drive enclosure 124 and the inner enclosure 121 are integrated, they can be formed into an integrated structure by injection molding or 3D printing, but not limited to the method of screwing, snap-fitting, or plugging.

[0059] The inclined surface 124c is located on the side of the second flange 124b facing away from the bottom surface 111a, and the distance between the inclined surface 124c and the bottom surface 111a gradually decreases along the direction of positive rotation.

[0060] Under the action of external force, the drive bracket 12 rotates in the forward direction relative to the first housing 11. Simultaneously, the first flange 124a pushes against the movable member 13, and the inclined surface 124c of the second flange 124b also pushes against the movable member 13. This causes the movable member 13 to move from the highest side to the lowest side of the inclined surface 124c under the pushing action of the inclined surface 124c. The suction cup structure 14 then moves towards the external carrier under the action of the movable member 13 until it is in a suction state, thus achieving relative fixation between the folding bracket 1 and the external carrier, ensuring the effective fixation of the product 2 to be fixed by the folding bracket 1. Support; conversely, the drive bracket 12 rotates in the opposite direction to the first housing 11 under the action of external force. At the same time, the first flange 124a pushes against the movable part 13, and the inclined surface 124c of the second flange 124b pushes against the movable part 13, so that the movable part 13 moves from the lowest side of the inclined surface 124c to the highest side of the inclined surface 124c under the pushing action of the inclined surface 124c. The suction cup structure 14 moves away from the external carrier under the action of the movable part 13 to a non-suction state detached from the external carrier. At this time, the relative position between the folding bracket 1 and the external carrier can be changed, and the folding bracket 1 can be stored.

[0061] It should be noted that when the connecting ring is in a folded, non-expanded state relative to the base 10, the protruding part of the second sub-shell 113 facing away from the bottom surface 111a and the aromatherapy storage box 41 are both located within the annular hole of the connecting ring. In this way, the base 10 and the aromatherapy storage box 41 can make reasonable use of the annular hole area of ​​the connecting ring, thereby further effectively reducing the space occupancy rate of the folding bracket 1 when it is in an idle state.

[0062] like Figures 10-12As shown, one of the outer periphery of the connecting shell 112 and the inner side of the outer wall 122 is provided with a plurality of toothed grooves 122a arranged around the axis of the annular hole of the connecting shell 112; the base 10 also includes a locking structure 18, which is disposed on the other of the outer periphery of the connecting shell 112 and the inner side of the outer wall 122, and the locking structure 18 is engaged with one of its toothed grooves 122a to restrict the rotation of the drive bracket 12 relative to the first shell 11. The locking structure 18 includes a locking block 181 and a spring 182. One end of the spring 182 is fixedly connected to the other of the outer periphery of the connecting shell 112 and the inner side of the outer wall 122, and the other end of the spring 182 is fixedly connected to the locking block 181, which is engaged with the toothed groove 122a. By designing the tooth structure 18 and the tooth groove 122a, when the drive bracket 12 rotates relative to the first housing 11, the tooth structure 18 moves in multiple tooth grooves 122a and will emit a "click-click-click" damping sound. After the external force acting on the drive bracket 12 is removed, the tooth structure 18 engages with one of its tooth grooves 122a, which can restrict the rotation of the drive bracket 12 relative to the first housing 11, so as to ensure the stability of the suction cup structure 14 in the adsorption state.

[0063] like Figure 5 , Figure 6 , Figures 10-12 As shown, the connecting wall 123 has an arc-shaped through hole 123a arranged around the axis of the annular hole of the connecting shell 112. The first shell 11 also includes a first mounting post 114, which passes through the arc-shaped through hole 123a and is fixedly connected to one of the connecting shell 112 and the first sub-shell 111. The first mounting post 114 has a first mounting hole 114a. The other of the connecting shell 112 and the first sub-shell 111 has a first through hole 112a corresponding to the first mounting hole 114a. The base 10 also includes a first fastener 191, which passes through the first through hole 112a and is connected to the first mounting hole 114a to position the connecting shell 112 on the first sub-shell 111. This facilitates the installation and removal of the connecting shell 112 and the first sub-shell 111.

[0064] The first mounting post 114 may, but is not limited to, form an integral structure with one of the connecting shell 112 and the first sub-shell 111 by injection molding or 3D printing.

[0065] The first mounting hole 114a can be a first threaded hole, in which case the first fastener 191 is a first screw, the first screw passes through the first through hole 112a and connects with the first threaded hole to lock and fix the connecting shell 112 to the first sub-shell 111; the first mounting hole 114a can also be a first locking hole, in which case the first fastener 191 is a first locking pin, the first locking pin passes through the first through hole 112a and engages with the first locking hole to lock and fix the connecting shell 112 to the first sub-shell 111.

[0066] like Figure 5 , Figure 6 , Figures 10-12 As shown, the first housing 11 further includes a second mounting post 115, which is fixedly connected to one of the connecting housing 112 and the second sub-housing 113. The second mounting post 115 has a second mounting hole 115a. The other of the connecting housing 112 and the second sub-housing 113 has a second through hole 113c corresponding to the second mounting hole 115a. The base 10 further includes a second fastener 192, which passes through the second through hole 113c and is connected to the second mounting hole 115a to position the second sub-housing 113 on the connecting housing 112. This facilitates the installation and removal of the second sub-housing 113 from the connecting housing 112.

[0067] The second mounting post 115 may, but is not limited to, form an integral structure with one of the connecting shell 112 and the second sub-shell 113 by injection molding or 3D printing.

[0068] The second mounting hole 115a can be a second threaded hole, in which case the second fastener 192 is a second screw, the second screw passes through the second through hole 113c and connects with the second threaded hole to lock and fix the second sub-shell 113 to the connecting shell 112; the second mounting hole 115a can also be a second locking hole, in which case the second fastener 192 is a second locking pin, the second locking pin passes through the second through hole 113c and engages with the second locking hole to lock and fix the second sub-shell 113 to the connecting shell 112.

[0069] like Figures 8-9 As shown, the base 10 also includes an anti-slip part 15 disposed on the periphery of the outer wall 122. The anti-slip part 15 includes a plurality of inclined convex ridges or concave strips spaced apart around the hole axis of the annular hole of the connecting shell 112. By designing the anti-slip part 15 with a plurality of inclined convex ridges or concave strips, the friction between the user's fingers and the outer wall 122 can be increased, making it easier for the user to rotate the drive bracket 12.

[0070] like Figures 5-10As shown, the bottom surface 111a of the first housing 11 has a through hole 111b and a groove 111c communicating with the through hole 111b. A portion of the suction cup structure 14 is located on one side of the bottom surface 111a of the first housing 11, and the remaining portion of the suction cup structure 14 passes through the through hole 111b and is connected to the movable member 13. The base 10 also includes an elastic member 16, located between the suction cup structure 14 and the bottom surface 111a of the groove 111c. The elastic member 16 is connected to both the suction cup structure 14 and the bottom surface 111a of the groove 111c. The elastic member 16 is used to drive the suction cup structure 14 to reset during the recovery of elastic deformation. Specifically, the elastic member 16 generates elastic deformation during the forward rotation of the drive bracket 12 relative to the first housing 11, and also recovers elastic deformation during the reverse rotation of the drive bracket 12 relative to the first housing 11. The elastic member 16 can be a spring or a sheet spring. The suction cup structure 14 includes a suction nozzle 141 and a connector 142 detachably connected to the suction nozzle 141. The suction nozzle 141 is located on the side of the bottom surface 111a of the first sub-shell 111, and the connector 142 is connected to the movable part 13 through a through hole 111b. By designing the through hole 111b on the bottom surface 111a of the first shell 11, part of the suction cup structure 14 can be connected to the movable part 13 through the through hole 111b. This makes reasonable use of the internal space of the first shell 11, making the suction cup structure 14 and the first shell 11 more compact in structure, which can effectively reduce the volume of the base 10, thereby reducing the overall volume of the folding bracket 1. By designing the elastic element 16, when the drive bracket 12 rotates forward relative to the first housing 11 under the action of an external force, the suction cup structure 14 moves towards the external carrier under the action of the movable element 13. The movement of the suction cup structure 14 causes the elastic element 16 connected to it to undergo elastic deformation until the suction cup structure 14 is in a suction state that attracts the external carrier. Conversely, when the drive bracket 12 rotates in the opposite direction relative to the first housing 11 under the action of an external force, the suction cup structure 14 moves away from the external carrier under the action of the movable element 13. The movement of the suction cup structure 14 causes the elastic element 16 connected to it to gradually recover its elastic deformation until the suction cup structure 14 is in a non-suction state that is detached from the external carrier. By designing a groove 111c on the bottom surface 111a of the first housing 11, the groove 111c provides a space for the elastic element 16. This makes the elastic element 16 and the first housing 11 more compact in structure, which can effectively reduce the volume of the base 10, thereby reducing the overall volume of the folding bracket 1.

[0071] It is worth mentioning that when the folding bracket 1 is attached to the external carrier by the suction cup structure 14, the elastic element 16 can support the first sub-shell 111 on the one hand, and buffer and dampen on the other hand. Especially for the application scenario where the folding bracket 1 is attached to the front cockpit platform of the vehicle, the buffer and damping effect of the elastic element 16 can effectively reduce the shaking of the product 2 to be fixed on the adsorption component.

[0072] The folding bracket 1 also includes an adhesive component 50, through which the base 10 is connected to the external carrier. The adhesive component 50 includes a base layer 51 and an adhesive layer 52. The adhesive layer 52 is disposed on the side of the base layer 51 facing away from the bottom surface 111a. The base layer 51 can be made of, but is not limited to, plastic or glass, and its shape can be rectangular. The adhesive layer 52 can be double-sided adhesive or soft tape, and its shape can be circular. By designing the adhesive component 50, when encountering an external carrier that is difficult for the suction cup structure 14 to adhere to (e.g., the suction cup structure 14 may become loose when adhering), the folding bracket 1 can be firmly fixed to the external carrier using the adhesive component 50. It should be noted that when the adhesive component 50 is needed to fix the folding bracket 1 to the external carrier, the suction cup structure 14 is first adsorbed onto the base layer of the adhesive component 50, and then the adhesive layer of the adhesive component 50 is adhered to the surface of the external carrier.

[0073] like Figure 5 , Figure 6 and Figure 13 As shown, the fixing component 30 positions the product 2 to be fixed by magnetic adsorption. The fixing component 30 includes a second housing 31 and a magnetic suction member 32. The second housing 31 is annular and rotatably connected to the connecting ring. The second housing 31 has a first receiving cavity 31a. The magnetic suction member 32 is disposed in the first receiving cavity 31a. When the connecting ring is in a stacked, non-unfolded state relative to the base 10, and the fixing component 30 is in a stacked, non-unfolded state relative to the connecting ring, the cover 412 is located in the annular hole of the connecting ring and the annular hole of the second housing 31. In this way, the aromatherapy storage box 41 can also make reasonable use of the annular hole area of ​​the second housing 31 to further reduce the space occupation rate when the folding bracket 1 is in an idle state.

[0074] The specific material of the second housing 31 is not limited here, and designers can make a reasonable choice according to actual needs; for example, the material of the second housing 31 can be, but is not limited to, plastic or rubber. The magnetic component 32 includes a magnet, and the shape and number of the magnetic component 32 are not limited here, and designers can make a reasonable design according to actual needs; for example, when the number of magnetic components 32 is one, the single magnetic component 32 can be in the shape of a ring; or, for example, when the number of magnetic components 32 is multiple, the multiple magnetic components 32 can be in the shape of a fan, and the multiple fan-shaped magnetic components 32 are arranged at equal intervals around the axis of the annular hole of the second housing 31 in the second receiving cavity 33a.

[0075] When the aroma storage part 40 is a virtual structure such as a space for storing the aroma 17, the aroma storage part 40 can be provided on the fixing component 30. In this case, the aroma storage part 40 includes a first receiving cavity 31a, and the second housing 31 also has an aroma hole 41a that communicates with the first receiving cavity 31a.

[0076] The shape and number of aroma holes 41a are not limited here, and designers can make reasonable designs according to actual needs. For example, when there is one aroma hole 41a, the aroma hole 41a can be annular. Or, for example, when there are multiple aroma holes 41a, the multiple aroma holes 41a can be waist-shaped, and the multiple waist-shaped aroma holes 41a are arranged at equal intervals around the axis of the annular hole of the second housing 31 on the second housing 31.

[0077] By designing the aromatherapy storage unit 40 within the first receiving cavity 31a of the second housing 31, the internal space of the second housing 31 is fully utilized to provide a comfortable atmosphere for the user.

[0078] When the aromatherapy storage section 40 is a virtual structure such as a space for storing aromatherapy diffusers 17, the aromatherapy storage section 40 can be mounted on the fixing component 30, such as... Figure 14 As shown, in other embodiments, the fixing component 30 positions the product 2 to be fixed by magnetic adsorption. The fixing component 30 includes a third housing 33 and a magnetic suction member 32. The third housing 33 is rotatably connected to the connecting structure 20 (such as the connecting ring described above) and has a second receiving cavity 33a. The second receiving cavity 33a includes a first sub-cavity 33b and a second sub-cavity 33c disposed around the first sub-cavity 33b. The magnetic suction member 32 is disposed in one of the first sub-cavity 33b and the second sub-cavity 33c. The aromatherapy storage part 40 includes the other of the first sub-cavity 33b and the second sub-cavity 33c. The third housing 33 also has an aromatherapy hole 41a communicating with the other of the first sub-cavity 33b and the second sub-cavity 33c.

[0079] The specific material of the third housing 33 is not limited here, and designers can make a reasonable choice according to actual needs; for example, the material of the third housing 33 can be, but is not limited to, plastic or rubber. The shape and number of the aromatherapy holes 41a are not limited here, and designers can make a reasonable design according to actual needs; for example, when there is only one aromatherapy hole 41a, it can be annular; or, when there are multiple aromatherapy holes 41a, they can be waist-shaped, and the multiple waist-shaped aromatherapy holes 41a are evenly spaced around the axis of the annular hole of the connecting ring on the third housing 33. The second receiving cavity 33a in the third housing 33 is divided into two regions: a first sub-cavity 33b and a second sub-cavity 33c. The second sub-cavity 33c is located outside and surrounds the first sub-cavity 33b. The magnetic attractor 32 includes a magnet. The shape and number of the magnetic attractor 32 are not limited here; designers can design them reasonably according to actual needs. For example, when there is only one magnetic attractor 32, it can be arranged in a ring in the second sub-cavity 33c, while the aromatherapy diffuser 17 is located in the first sub-cavity 33b. The third housing 33 has an aromatherapy hole 41a corresponding to the first sub-cavity 33b, communicating with the first sub-cavity 33b. When there are multiple magnetic attractors 32, they can be arranged in a fan shape, and these multiple fan-shaped magnetic attractors 32 are equally spaced around the axis of the annular hole of the connecting ring in the second sub-cavity 33c. In this case, the aromatherapy diffuser 17 is located in the first sub-cavity 33b, and the third housing 33 has an aromatherapy hole 41a corresponding to the first sub-cavity 33b. The third housing 33 has an aromatherapy hole 41a communicating with the first sub-cavity 33b at a certain position. For example, when there is only one magnetic suction member 32, the magnetic suction member 32 can be circularly arranged in the first sub-cavity 33b, and the aromatherapy 17 is arranged in the second sub-cavity 33c. The third housing 33 has an aromatherapy hole 41a communicating with the second sub-cavity 33c at a position corresponding to the second sub-cavity 33c. When there are multiple magnetic suction members 32, the multiple magnetic suction members 32 can be fan-shaped, and the multiple fan-shaped magnetic suction members 32 are arranged in the first sub-cavity 33b around the axis of the annular hole of the connecting ring. In this case, the aromatherapy 17 is arranged in the second sub-cavity 33c, and the third housing 33 has an aromatherapy hole 41a communicating with the second sub-cavity 33c at a position corresponding to the second sub-cavity 33c.

[0080] By designing the aromatherapy storage unit 40 within the first sub-cavity 33b or the second sub-cavity 33c of the second receiving cavity 33a of the third housing 33, the internal space of the third housing 33 is fully utilized to provide a comfortable atmosphere for the user.

[0081] When the aroma storage part 40 is a virtual structure such as a space for storing the aroma 17, the aroma storage part 40 can also be provided on the connecting structure 20 (such as the connecting ring mentioned above). In this case, the interior of the connecting ring is hollow to form a third receiving cavity (not shown in the figure). The aroma storage part 40 includes the third receiving cavity, and the connecting ring also has an aroma hole 41a that communicates with the third receiving cavity.

[0082] Here, the shape and number of aroma holes 41a are not limited, and designers can make reasonable designs according to actual needs. Taking the connecting structure 20 including the connecting ring as an example, for example, when the number of aroma holes 41a is one, the aroma hole 41a can be annular; for example, when the number of aroma holes 41a is multiple, the multiple aroma holes 41a can be waist-shaped, and the multiple waist-shaped aroma holes 41a are arranged at equal intervals around the axis of the annular hole of the connecting ring on the connecting ring.

[0083] By designing the aromatherapy storage unit 40 within the third receiving cavity of the connecting ring, the internal space of the connecting structure 20 is fully utilized to provide a comfortable atmosphere for the user.

[0084] like Figure 15 As shown, the folding bracket 1 also includes a wireless charging module 60, which is disposed within the second receiving cavity 33a of the second housing 31. When the product 2 to be fixed is positioned on the second housing 31 by the magnetic suction member 32, if the current battery level of the product 2 to be fixed is lower than the preset battery level, the wireless charging module 60 supplies power to the product 2 to be fixed wirelessly. The specific value of the preset battery level is not limited here; designers can design it reasonably according to actual needs. For example, the preset battery level can be the full charge of the power supply 61, 80% of the full charge of the power supply 61, or 50% of the full charge of the power supply 61. By designing the wireless charging module 60 and placing it within the second receiving cavity 33a of the second housing 31, the folding bracket 1, in addition to providing support for the product 2 to be fixed, can also act as a wireless power bank to charge the product 2 to be fixed.

[0085] Specifically, the wireless charging module 60 includes a power supply 61 and a charging coil 62; the power supply 61 is disposed within the second receiving cavity 33a; the charging coil 62 is disposed within the second receiving cavity 33a and electrically connected to the power supply 61; when the product 2 to be fixed is positioned on the second housing 31 by the magnetic suction member 32, if the current power of the product 2 to be fixed is lower than the preset power, the power supply 61 supplies power to the product 2 to be fixed through the charging coil 62. It should be noted that wireless charging is not the focus of this application, so the specific implementation of wireless charging will not be described in detail here. Its design for adjusting current and voltage to match the charging needs of different devices can be directly implemented using wireless charging technology in related technologies, and its design for multiple safety measures such as overcharge, over-discharge, short circuit, and overheat protection can also be directly implemented using wireless charging technology in related technologies.
