Description

Technical Field

[0001] This utility model relates to the field of sports protective gear technology, and in particular to a knee brace. Background Technology

[0002] Knee braces are used to protect the human knee joint, providing warmth and reducing the risk of knee injury during exercise. Depending on the intended use case, support strips can be incorporated into the main body of the knee brace (commonly an elastic tubular structure) to increase its support strength.

[0003] In the existing technology, the methods of fixing the support strip and the body include direct sewing, sewing with an internal pocket, fastening with Velcro, and thermoforming. Among these, fastening with Velcro allows for a detachable connection between the support strip and the body, making it easier to install and remove the support strip and thus expanding the applicability of the knee brace.

[0004] However, the Velcro fastening method involves attaching the support strip to the main body along its length. As a result, during the use of the knee brace, the repeated bending of the joint can easily cause the Velcro between the support strip and the main body to curl and separate, affecting the comfort of the knee brace. Furthermore, the Velcro connection method also results in significant noise during disassembly and assembly. Consequently, the existing detachable connection method between the support strip and the main body is limited and presents many inconveniences. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a knee brace in which the connection method between the support strip and the main body can be selected and set according to needs, enriching the connection methods between the support strip and the main body. Moreover, the connection method between the support strip and the main body is more convenient than the Velcro fixing method, enabling quick removal and removal of both without affecting wearing comfort, and has the advantages of low noise during assembly and disassembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a knee brace, comprising a body and at least one support strip, the support strip having at least one upper fixing part and at least one lower fixing part, the upper fixing part and the lower fixing part being detachably connected to the body via connectors;

[0007] One of the connectors is a cloth bag connection or a card slot connection, and the other connector can be any one of the following: cloth bag connection, magnetic connection, snap-on connection, or card slot connection.

[0008] Understandably, the body can take the form of a sheet or a tubular structure. In general, the body is a tubular structure of elastic knitted material. The body shown in this application is a tubular body. In actual use, the body can be sheet-like or other structures.

[0009] One or more support strips can be connected to the main body, and the number of support strips is set according to the applicable scenario of the knee brace. At the same time, the shape of the support strip can be a strip structure, X-shape, Y-shape, etc., and the support strip has at least one upper fixing part and at least one lower fixing part. The support strip is made of elastic plastic, such as nylon, TPE, etc., or it can be a flat straight strip structure formed by compression of a helical spring in the prior art, so that the support strip has the ability to recover its deformation.

[0010] To achieve a detachable connection between the support bar and the main body, at least the upper and lower ends of the support bar and the main body should be detachably connected. The middle part of the support bar can also be provided with detachable connection points according to the different shapes of the support bar or the stress requirements. The detachable connection points can be fixed by any method such as magnetic connection, snap connection, Velcro connection, or locking connection.

[0011] The upper fixing part (equivalent to the upper end or near the upper end of the support bar) and the lower fixing part (equivalent to the lower end or near the lower end of the support bar) are respectively connected to the body via connectors, so that the entire support bar and the body have at least 2n detachable connection methods. k-1 (n is the number of types of connectors, k is the number of connectors on the support bar). Based on at least 4 connection methods of the connectors, there are at least 8 detachable combination methods between the strip-shaped support bar and the body. Therefore, when the support bar and the body are connected in this application, the most suitable combination connection method can be selected according to the different shapes and different stress points of the support bar, so as to ensure a stable connection between the support bar and the body, while also facilitating disassembly and assembly.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0048] like Figure 1-15 As shown, a knee brace includes a body 200 and a support strip 100. The support strip 100 has at least one upper fixing part 11 and at least one lower fixing part 13. The upper fixing part 11 and the lower fixing part 13 are detachably connected to the body 200 by connectors. One of the connectors is a cloth bag connection or a slot connection, and the other connector includes any one of the following connection methods: cloth bag connection, magnetic connection, buckle connection, and slot connection.

[0049] It is understood that the support bar 100 of this application can be a strip structure, X-shaped, Y-shaped, etc., and the support bar 100 has at least one upper fixing part 11 and at least one lower fixing part 13. The upper fixing part 11 and the lower fixing part 13 can be at the end of the support bar 100 or a part of the structure near the end of the support bar 100. For example... Figure 1 , 2 As shown in figures 4, 6, 8, 9, 10, 11, 12, 13, 14, and 15, the support bar 100 is a conventional strip-shaped structure, including an upper fixing part 11 and a lower fixing part 13. Figure 5 , 7 As shown, the support bar 100 is X-shaped, and therefore has two upper fixing parts 11 and two lower fixing parts 13. Figure 3 As shown, the support bar 100 has a Y-shaped structure and includes two upper fixing parts 11 and one lower fixing part 13.

[0050] The support strip 100 of this application is made entirely of elastic plastic, such as nylon, TPE, etc., or it can be a flat, straight strip structure formed by compression of a helical spring in the prior art, so that the support strip 100 has the ability to recover its deformation.

[0051] To achieve a detachable connection between the support bar 100 and the body 200, at least the upper and lower ends of the support bar 100 and the body 200 are detachably connected. The middle part of the support bar 100 may also be provided with detachable connection points according to the different shapes of the support bar 100 or the stress requirements. The detachable connection points can be fixed by any method such as magnetic connection, snap connection, Velcro connection, or locking connection.

[0052] In this application, the upper fixing part 11 and the lower fixing part 13 of the support bar 100 are connected to the body 200 via connectors. One connector can only be either a cloth bag connection or a slot connection, while the other connector can be at least a cloth bag connection, a magnetic connection, a snap-on connection, or a slot connection. This results in at least 2n detachable connection methods between the support bar 100 and the body 200. k-1 (n is the number of types of connectors, and k is the number of connectors on the support bar 100). Based on at least 4 connection methods of the connectors, the strip-shaped support bar 100 and the body 200 have at least 8 detachable combination methods. Therefore, when the support bar 100 and the body 200 are connected, the most suitable combination connection method can be selected according to the different shapes and different stress points of the support bar 100, so as to ensure the stable connection between the support bar 100 and the body 200, while also facilitating disassembly and assembly.

[0053] In this application, when the support bar 100 and the body 200 are connected, the most suitable combination connection method can be selected according to the different shapes and stress points of the support bar 100, so as to ensure a stable connection between the support bar 100 and the body 200, while also facilitating disassembly and assembly.

[0054] In this application, the support bar 100 and the main body 200 are detachably connected, so that the main body 200 can be fixed with the support bar 100 with different support strengths. Users can choose support bars 100 with different strengths according to their own weight and endurance, thus expanding the application range of the knee brace.

[0055] Depending on the different structures and quantities of the connectors and the different structures of the support bar 100, the support bar 100, the connectors, and the body 200 can have multiple connection methods. Therefore, this application will show the specific structure of each connector separately. By combining the support bar 100 with different connectors, different connection methods than the body 200 can be obtained.

[0056] In some embodiments of this application, the connector adopts the first type of cloth bag connection method.

[0057] The connector includes a connecting sleeve 202, which is fixed to the body 200 and has at least one opening. The upper fixing part 11 and / or the lower fixing part 13 are detachably connected to the connecting sleeve 202 and inserted into it.

[0058] Taking a support strip 100 on one side of the main body 200 as an example, in order to connect the support strip 100 with the main body 200, a connecting sleeve 202 is provided on the main body 200. The connecting sleeve 202 is made of a high-elastic material, such as nylon or PSA fiber. The connecting sleeve 202 covers the surface of the main body 200 and connects with the main body 200, forming at least one opening with the main body 200. When the support strip 100 and the main body 200 are connected, the upper fixing part 11 and / or the lower fixing part 13 can be directly inserted into the connecting sleeve 202 to achieve a detachable connection between the support strip 100 and the connecting sleeve 202, thereby achieving a detachable connection between the support strip 100 and the main body 200.

[0059] Specifically, such as Figure 4 As shown, when the support bar 100 is a strip structure, the connectors of the upper fixing part 11 and the lower fixing part 13 of the support bar 100 both adopt the first type of bag connection method. Then, the upper fixing part 11 and the lower fixing part 13 of the support bar 100 both adopt an arc-shaped insertion structure. Two connecting sleeves 202 that cooperate with the support bar 100 are set on the body 200. Each connecting sleeve 202 and the body 200 form a "pocket structure". Since the support bar 100 has a certain elasticity, the external force drives the support bar 100 to deform, which can insert or separate the two ends of the support bar 100 from the cooperating connecting sleeves 202 respectively, so as to realize the detachable connection between the support bar 100 and the body 200.

[0060] like Figure 5 As shown, the support bar 100 is X-shaped and has two upper fixing parts 11 and two lower fixing parts 13. The connectors used by the two upper fixing parts 11 and the two lower fixing parts 13 respectively adopt the first type of cloth bag connection method. Correspondingly, each upper fixing part 11 and each lower fixing part 13 is an arc-shaped plug-in structure. When the support bar 100 is detachably connected to the body 200, four connecting sleeves 202 need to be fixed on the body 200.

[0061] In some embodiments of this application, the connector adopts a second type of cloth bag connection method.

[0062] By improving the structure of the connecting sleeve 202 and correspondingly setting a connecting structure at the end of the support bar 100, a new connector can be formed, which is the second type of bag connection method. Specifically, the connector includes the connecting sleeve 202 and a barb structure. The connecting sleeve 202 has two opposite openings, and the barb structure is set on the upper fixing part 11 and / or the lower fixing part 13. The barb structure passes through both openings and cooperates with one of the openings. The connecting sleeve 202 is equivalent to a through-slot structure. The end of the support bar 100 passes through this through-slot structure and is fixed to the connecting sleeve 202 by the barb structure at the end of the support bar 100, thereby connecting the support bar 100 and the body 200.

[0063] like Figure 1 , 2 As shown, the support strip 100 has a strip-shaped structure with an upper fixing part 11 and a lower fixing part 13. The connectors of the upper fixing part 11 and the lower fixing part 13 are both of the second type of fabric bag connection method. Both the upper fixing part 11 and the lower fixing part 13 cooperate with the connecting sleeve 202 with two openings. The upper and lower ends of the support strip 100 are provided with barb structures. During installation, the support strip 100 is passed through each connecting sleeve 202 from top to bottom to realize the assembly of the support strip 100 and the body 200. Due to this structure, the two ends of the support strip 100 have a certain range of movement. In order to increase the stability of the support strip 100 in use, at least one connecting sleeve 202 with two openings can also be provided on the body 200 along the shape path of the support strip 100 to limit the middle part of the support strip 100 and prevent the support strip 100 from deviating too far when the knee pad is in use.

[0064] like Figure 3 As shown, the support bar 100 has a Y-shaped structure with two upper fixing parts 11 and one lower fixing part 13. The connectors of the two fixing parts 11 and the lower fixing part 13 are all of the second type of cloth bag connection method. Similarly, the ends of the two upper fixing parts 11 and the lower fixing part 13 are provided with barb structures. The main body 200 is provided with four connecting sleeves 202 with two openings. One connecting sleeve 202 is in the middle, and the connection positions of the remaining three connecting sleeves 202 are adapted to the shape of the support bar 100. During installation, the support bar 100 is first matched with the connecting sleeve 202 in the middle, and then the two upper fixing parts 11 and the lower fixing parts are passed through the connecting sleeves 202 respectively, so as to realize the assembly of the support bar 100 and the main body 200.

[0065] like Figure 7As shown, the support bar 100 has an X-shaped structure with two upper fixing parts 11 and two lower fixing parts 13. The connectors of the two fixing parts 11 and the two lower fixing parts 13 are all of the second type of cloth bag connection method. Similarly, the ends of the two upper fixing parts 11 and the two lower fixing parts 13 are provided with barb structures. The body 200 is provided with five connecting sleeves 202 with two openings. The layout of the five connecting sleeves 202 on the body 200 is similar to the five-point layout on a die. One connecting sleeve 202 is in the middle, and the connection positions of the remaining four connecting sleeves 202 are adapted to the shape of the support bar 100. During installation, the support bar 100 is first matched with the connecting sleeve 202 in the middle, and then the two upper fixing parts 11 and the two lower fixing parts are passed through the connecting sleeves 202 respectively, so as to realize the assembly of the support bar 100 and the body 200.

[0066] Since the connector can be either the first type of bag connection or the second type of bag connection, different connector structures can be adopted for each upper fixing part 11 and / or each lower fixing part 13 on the support bar 100 of different shapes. Therefore, even if the connectors all adopt the bag connection method, there can be multiple layout methods.

[0067] For example, when the support bar 100 has an upper fixing part 11 and a lower fixing part 13, the upper fixing part 11 and the body 200 are connected using a first type of fabric sleeve connection method. The lower fixing part 13 can be connected to the body 200 using either the first or second type of fabric sleeve connection method. Similarly, if the upper fixing part 11 and the body 200 are connected using the second type of fabric sleeve connection method, the lower fixing part 13 can also be connected to the body 200 using either the first or second type of fabric sleeve connection method. By analogy, when the support bar 100 has multiple upper fixing parts 11 and multiple lower fixing parts 13, even if all the connecting parts are fabric sleeve connection methods, the support bar 100 and the body 200 can have multiple combination methods.

[0068] In some embodiments of this application, in order to achieve the cooperative use of the barb structure and the connecting sleeve 202, the barb structure includes at least one elastic part 105, which extends outward along the upper fixing part 11 and / or the lower fixing part 13 and is inclined toward the middle of the support bar 100.

[0069] like Figure 1 , 2As shown in Figures 3, 6, 7, and 15, the barb structure of this application includes two elastic portions 105. The elastic portions 105 are made of elastic plastic or similar materials. Because the elastic portions 105 have a certain degree of elasticity, the distance between the elastic portions 105 and the support strip 100 (upper fixing portion 11 and / or lower fixing portion 13) can vary. The opening distance of the connecting sleeve 202 is less than the maximum distance between the two elastic portions 105, allowing the barb structure to pass through the connecting sleeve 202 and connect to it, thus preventing separation between the support strip 100 and the connecting sleeve 202. In other embodiments of this application, the elastic portions 105 of the barb structure can be three, four, or more, with each elastic portion 105 radiating outwards from the end of the support strip 100, all capable of connecting the support portion and the connecting sleeve 202. Furthermore, besides the hook-shaped structure shown in the figures, the elastic portions 105 can also be rectangular blocks, strips, or other similar structures.

[0070] In some embodiments of this application, the connector adopts a snap-fit ​​connection method.

[0071] Understandably, the snap-fit ​​connector can cooperate with the upper fixing part 11 and / or lower fixing part 13 of the support bar 100, and the multiple connectors of the support bar 100 and the body 200, except for one connector which needs to adopt a cloth bag connection method or a slot connection method, can all adopt a snap-fit ​​structure.

[0072] like Figure 9 As shown, this application provides a first type of snap-fit ​​connector, which includes a snap-fit ​​protrusion 125 and a snap-fit ​​base 204. Either the snap-fit ​​base 204 or the snap-fit ​​protrusion 125 is connected to the body 200 or the support bar 100. In the figure, the snap-fit ​​base 204 is fixed to the body 200, and the snap-fit ​​protrusion 125 is fixed to the support bar 100. The snap-fit ​​base 204 includes a snap-fit ​​groove 2041, within which a retractable card 2042 is provided. In use, the snap-fit ​​protrusion 125 is located within the snap-fit ​​groove 2041 and locked by the card 2042. When the card 2042 retracts, the snap-fit ​​protrusion 125 unlocks from the snap-fit ​​groove 2041.

[0073] The overall structure of the connector of the above-mentioned snap-fit ​​structure is designed with reference to the snap-fit ​​structure of the "Apple Vision Pro headband" in the prior art. The card 2042 can engage with the snap-fit ​​protrusion 125 that enters the snap-fit ​​groove 2041 under the action of the corresponding elastic element (not shown in the figure). The snap-fit ​​protrusion 125 adopts a protrusion structure so that a recessed structure 126 for the card 2042 to engage can be formed between the snap-fit ​​protrusion 125 and the connecting section 140. Through the cooperation of the card 2042 and the snap-fit ​​protrusion 125, a stable connection between the elastic body 100 and the elastic body 200 is ensured. When it is necessary to disassemble the elastic body 100, pull the pull cord 2043 connected to the card 2042, which can drive the card 2042 to retract and separate from the snap-fit ​​protrusion 125, thereby unlocking the snap-fit ​​protrusion 125 and the recessed structure 126. At this time, the snap-fit ​​protrusion 125 and the snap-fit ​​groove 2041 can be separated, thereby disassembling the corresponding part of the support bar 100 and the body 200.

[0074] In addition to the snap-fit ​​connection structure described above, some embodiments of this application also provide a second snap-fit ​​structure. Specifically, the connector includes a detachably connected connecting seat 23 and an elastic snap 20. The connecting seat 23 is connected to the body 200, and the elastic snap 20 is connected to the support bar 100; or the connecting seat 23 is connected to the support bar 100, and the elastic snap 20 is connected to the body 200. For ease of distinction, this application refers to the connector using the snap-fit ​​structure of the connecting seat 23 and the elastic snap 20 (the second snap-fit ​​structure) as the first connecting component 2.

[0075] Understandably, either the connecting seat 23 or the elastic buckle 20 of the first connecting component 2 can be connected to the support bar 100 or the body 200. A detachable connection between the support bar 100 and the body 200 can be achieved simply by connecting the connecting seat 23 and the elastic buckle 20. Of course, for ease of operation, this application fixes the connecting seat 23 to the body 200 and connects the elastic buckle 20 to the support bar 100.

[0076] In the first connecting component 2, the connecting seat 23 and the elastic buckle 20 are connected by a snap-fit. In this way, a snap-fit ​​groove can be set on the connecting seat 23. The elastic buckle 20 is a plastic elastic sheet. The elastic buckle 20 and the connecting seat 23 can be detachably connected by using the snap-fit ​​method.

[0077] In this application, the elastic buckle 20 includes a button 21 and an elastic element 22. The button 21 is slidably connected to the support bar 100, and the elastic element 22 is located between the button 21 and the support bar 100. The connecting seat 23 is provided with a fixing protrusion 25, and the button 21 slides and engages or disengages with the fixing protrusion 25. Figure 10 , 11As shown, the connecting seat 23 has a plate-like structure and is fixed to the body 200 by rivets 101. A protruding fixing protrusion 25 is provided on the connecting seat 23, resembling a "7" shape, so that the fixing protrusion 25 and the elastic buckle 20 can be engaged. To ensure that the elastic buckle 20 can be detachably connected to the fixing protrusion 25... Figure 10 , 11 As shown, the elastic buckle 20 includes a knob 21 and an elastic element 22. The knob 21 includes a movable plate 211 with a plate-like structure and a fixed buckle 212, which resembles a "7" structure, located below the movable plate 211. The fixed buckle 212 engages with the fixed protrusion 25, enabling the elastic buckle 20 to engage with the connecting seat 23. To facilitate the movement of the elastic buckle 20, an elastic element 22, which is a horizontally arranged spring, is provided between the knob 21 and the support bar 100. In use, the user applies force to the movable plate 211, driving the movable plate 211 to move and forcing the elastic element to compress. At this time, the fixed buckle 212 and the fixed protrusion 25 separate, and the external force is applied to move the support bar 100 away from the body 200, thus separating one end of the support bar 100 from the body 200. When it is necessary to connect one end of the support bar 100 to the body 200, simply apply pressure to the support bar 100 toward the body 200 while driving the moving plate 211 to move. Remove the external force on the moving plate 211, and the moving plate 211 moves under the action of the spring, driving the fixing buckle 212 to move and engage with the fixing protrusion 25, thus completing the connection between the support bar 100 and the body 200.

[0078] To facilitate the engagement of the dial 21 and the connecting seat 23, pressure is applied towards the connecting seat 23 (body 200), allowing the moving plate 211 of the dial 21 to move automatically and engage with the fixed protrusion 25 under the action of the elastic member 22. In another embodiment of this application, the dial 21 is provided with a guide slope 2121, and the fixed protrusion 25 is provided with a wedge surface 251 that cooperates with the guide slope 2121. Figure 10 , 11 As shown, a guide slope 2121 is provided on the bottom side wall of the fixing buckle 212, and a inclined wedge surface 251 is provided on the top side wall of the fixing protrusion 25. In use, when the guide slope 2121 of the fixing buckle 212 and the wedge surface 251 of the fixing protrusion 25 are engaged, the fixing buckle 212 (button 21) is subjected to a pressing force towards the connecting seat 23. Under the action of the fixing protrusion 25, the fixing buckle 212 moves horizontally.

[0079] To facilitate positioning and connection when the elastic buckle 20 and the connecting seat 23 are engaged, in another embodiment of this application, the connecting seat 23 is further provided with a protruding positioning protrusion 24, and the support bar 100 is provided with a positioning groove 111 that engages with the positioning protrusion 24. Figure 10 , 11As shown, the connecting seat 23 is provided with a positioning protrusion 24, which is arranged adjacent to the fixing protrusion 25. The support bar 100 is provided with a positioning groove 111 with a through hole structure. In use, the positioning groove 111 and the positioning protrusion 24 are engaged to achieve positioning. At this time, the fixing buckle 212 will be positioned on the fixing protrusion 25, which facilitates the connection between the fixing buckle 212 and the fixing protrusion 25.

[0080] Based on the structure of the first connecting component 2, when the support bar 100 is a strip structure and the connector only adopts the structure of the first connecting component 2, the first connecting component 2 can be set on the fixing part 11 on the support bar 100. Figure 9 In the middle), the first connecting component 2 can also be set on the lower fixing part 13 of the support bar 100. Figure 11 In the middle), the first connecting component 2 can also be respectively set on the upper fixing part 11 and the lower fixing part 13 of the support bar 100 (14 in the figure).

[0081] Similarly, among the multiple connectors between the support bar 100 and the body 200, except for one connector which needs to adopt a bag connection method or a slot connection method, the other connectors can all adopt any one or a combination of the first connecting component 2, the first type of bag connection method, the second type of bag connection method, and the first type of buckle connection method.

[0082] In some embodiments of this application, the connector adopts a slot connection method.

[0083] The connector includes a fixed base and a plug-in part that are plugged into each other. The fixed base is connected to the body 200 and the plug-in part is connected to the support bar 100, or the fixed base is connected to the support bar 100 and the plug-in part is connected to the body 200.

[0084] The card slot connection method is similar to that of the cloth bag connection method. The end of the support bar 100 is detachably separated from the body 200 by plugging it in. Therefore, the plug-in part and the fixing seat can be connected to the body 200 and the support bar 100 by means of either plugging in or fixing seat. By using the plugging in and fixing seat, the support bar 100 and the body 200 can be detachably connected.

[0085] To facilitate the connection between the connector and the mounting base, this application provides a connecting slot 203 on the mounting base, with one end of the connecting slot 203 being open. For example... Figure 8As shown in (a), the fixing base and the body 200 are fixed by means of adhesive bonding, riveting 101, etc. The connecting groove 203 provided on the fixing base is a rectangular groove structure with one end open and the groove closed. The insertion part is part of the support bar 100 and is located at the end of the support bar 100. In the figure, the insertion part is the lower fixing part 13. The insertion part is inserted into the fixing base along the connecting groove 203, which can realize the detachable connection between the lower fixing part 13 of the support bar 100 and the body 200. In other embodiments, the insertion part can also be the upper fixing part 11 or a block structure fixed on the upper fixing part 11.

[0086] To facilitate the separation of the support bar 100 and the fixing base, the plug-in portion can extend out of the connecting slot 203, such as... Figure 8 As shown in (b), the cross-section of the connecting slot 203 is a convex groove structure, the cross-section of the plug part is a convex structure, and the upper end of the plug part extends out of the slot of the connecting slot 203. When in use, the plug part can be moved by applying external force by using the part of the plug part that extends out of the connecting slot 203.

[0087] Similarly, among the multiple connectors between the support bar 100 and the body 200, except for one connector which needs to adopt a bag connection method or a slot connection method, the other connectors can adopt any one or a combination of the first connecting component 2, the first type of bag connection method, the second type of bag connection method, the first type of buckle connection method, and the slot connection method.

[0088] In some embodiments of this application, the connectors are magnetically attached.

[0089] In addition to the two bag connection methods, card slot connection structure, and two buckle connection structures mentioned above, the connector can also adopt a magnetic connection structure. For example... Figure 14 , 15 As shown, the connector employs a magnetic connection method. The connector includes a strong magnetic block 106 and a magnetic groove 201. The strong magnetic block 106 is fixed to the support bar 100, and the magnetic groove 201 is recessed into the body 200. Alternatively, the magnetic groove 201 can be located on the support bar 100, while the strong magnetic block 106 can be fixed to the body 200. The cooperation between the strong magnetic block 106 and the magnetic groove 201 allows for a detachable connection between the support bar 100 and the body 200.

[0090] Similarly, among the multiple connectors between the support bar 100 and the body 200, except for one connector which needs to adopt a bag connection method or a slot connection method, the other connectors can all adopt any one or a combination of the first connecting component 2, the first type of bag connection method, the second type of bag connection method, the first type of buckle connection method, and the slot connection method.

[0091] In addition to the magnetic attraction structure described above, in some embodiments of this application, the connector may also be a second type of magnetic attraction connection. This type of connector includes a magnetically connected mounting base 31 and a magnetic base 32. The mounting base 31 is connected to the body 200, and the magnetic base 32 is fixed to the support bar 100. For ease of distinction, this application refers to the second type of magnetic attraction connection as the second connection component 3.

[0092] It is understandable that by setting magnets or magnets and magnetic metal on the mounting base 31 and magnetic base 32 respectively, a detachable connection between the mounting base 31 and magnetic base 32 can be achieved.

[0093] To achieve the positioning and magnetic attraction of the mounting base 31 and the magnetic base 32, the mounting base 31 includes a mounting plate 311 and a mounting protrusion 312. The mounting plate 311 is fixed to the body 200, and the mounting protrusion 312 protrudes in a direction away from the body 200. At least one first magnetic member 313 is fixed on the mounting protrusion 312, and the first magnetic member 313 is magnetically connected to the magnetic base 32. Figure 12 , 13 As shown, the mounting plate 311 is fixed to the body 200 by rivets 101. The mounting protrusion 312 protrudes outward from the body 200, and each first magnetic member 313 is embedded and fixed on the mounting protrusion 312. The first magnetic member 313 is a strong magnet, and the magnetic base 32 is provided with a magnet with the opposite magnetic force to the first magnetic member 313, or it can be made of a metal (such as iron) that can be magnetically attracted to the first magnetic member 313. Of course, the first magnetic member 313 can also be made of a metal material (such as iron) that can be magnetically attracted to a magnet, and the magnetic base 32 can also be provided with a strong magnet to achieve magnetic attraction between the first magnetic member 313 and the magnetic base 32. In this application, the first magnetic member 313 is a strong magnet that is injection molded into the mounting protrusion 312.

[0094] Furthermore, to facilitate the positioning and magnetic attraction of the magnetic base 32 and each of the first magnetic components 313, in another embodiment of this application, the magnetic base 32 has a groove-shaped structure. The magnetic base 32 is used to be engaged with the mounting protrusion 312. At least one second magnetic component 321 is provided inside the magnetic base 32, and each second magnetic component 321 cooperates with each of the first magnetic components 313. For example... Figure 12 , 13 As shown, the magnetic base 32 is provided with two second magnetic components 321. The second magnetic components 321 are powerful magnets and are fixed to the support strip 100 by in-mold injection molding.

[0095] Similarly, among the multiple connectors between the support bar 100 and the body 200, except for one connector which needs to adopt a bag connection method or a slot connection method, the other connectors can all adopt any one or a combination of the first connecting component 2, the second connecting component 3, the first bag connection method, the second bag connection method, the first buckle connection method, and the slot connection method.

[0096] In summary, this application provides seven types of connectors for connecting the support bar 100 and the body 200.

[0097] To demonstrate the different ways in which the connecting parts fit together on the support bar 100 and the body 200.
