Description

Technical Field

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

[0002] Typically, flip covers need to maintain both open and closed states. Generally, this is achieved using a spring mechanism combined with a snap-fit ​​structure. Specifically, when the flip cover is closed, the snap-fit ​​structure holds it in place; when the flip cover is open, the spring mechanism holds it in place.

[0003] However, this design involves many components, making the overall structure of the flip cover more complex and requiring more installation space. This not only makes the installation of the flip cover difficult but also increases the production cost of the flip cover. Utility Model Content

[0004] Therefore, it is necessary to provide a flip cover structure to solve the problem that the existing flip cover has a relatively complex overall structure and requires a large installation space.

[0005] The flip-top structure provided in this application includes a cover, a mounting base, a rotating shaft, and a spring-loaded component. The cover is rotatably connected to the mounting base via the rotating shaft. The two ends of the cover that rotate around the rotating shaft are defined as a cover plate segment and a mating segment, respectively. One end of the spring-loaded component is connected to the mounting base, and the other end is spring-loaded into the mating segment. The mating segment has a first contact portion and a second contact portion that are arranged opposite to each other. When the cover plate segment drives the mating segment to rotate around the rotation axis along the first rotation direction, and the first contact portion contacts the spring-loaded component, the cover plate segment is in an outward-folded state and the mounting base is in an exposed state. Furthermore, the spring-loaded component prevents the cover from rotating back along the second rotation direction. When the cover plate segment drives the mating segment to rotate around the rotation axis along the second rotation direction, and the second contact portion contacts the spring-loaded component, the cover plate segment can cover the mounting base. Furthermore, the spring-loaded component prevents the cover from rotating back along the first rotation direction. The first and second rotation directions are opposite. The spring-loaded component includes a first spring-loaded segment and a second spring-loaded segment. The spring-loaded component is mounted on the mounting base via the first spring-loaded segment. One end of the second spring-loaded segment is connected to the first spring-loaded segment, and the other end is spring-loaded into contact with the mating segment. The first and second spring-loaded segments are arranged along the length of the mounting base.

[0006] In one embodiment, when the first contact portion contacts the spring-loaded member, the spring-loaded member can drive the mating section to rotate around the rotation axis along the first rotation direction or have a rotational tendency along the first rotation direction through the first contact portion, and press the cover plate section and cover it on the mounting base.

[0007] And / or, when the second contact portion contacts the spring-loaded member, the spring-loaded member can drive the mating section to rotate around the rotation axis along the second rotation direction or has a rotational tendency along the second rotation direction, so that the cover plate section is turned outward and the mounting seat is exposed.

[0008] In one embodiment, when the first contact portion contacts the spring member, the surface of the spring member near the first contact portion can fit with the surface corresponding to the first contact portion, so that the cover plate segment remains covered on the mounting base.

[0009] And / or, when the second contact portion contacts the spring-loaded member, the surface of the spring-loaded member near the second contact portion can fit against the surface corresponding to the second contact portion, so that the cover plate segment remains in an outward-folded state and the mounting base is in an exposed state.

[0010] In one embodiment, the flip structure further includes a locking platform, one end of which is connected to the mounting base, and the other end extends toward the direction close to the first spring-loaded section. A locking groove is provided on one side of the locking platform, and a through groove is provided on the first spring-loaded section. The through groove is fitted around the periphery of the locking platform, and the side portion of the through groove near the second spring-loaded section is locked in the locking groove. When the second spring-loaded section is subjected to a pressing force applied by the mating section toward the direction away from the mounting base, the side portion of the through groove away from the second spring-loaded section can be pressed and abutted against the mounting base.

[0011] In one embodiment, there are multiple slots, and the multiple slots are spaced apart along the direction from the mounting base to the spring-loaded member.

[0012] In one embodiment, the flip structure further includes a support protrusion disposed on the side of the card plate away from the second spring-loaded section and connected to the mounting base, and the side portion of the through groove away from the second spring-loaded section can be pressed and abutted against the support protrusion.

[0013] In one embodiment, the card holder and the support protrusion are spaced apart to form a gap groove, and the flip structure also includes a spring tongue, one end of which is connected to the side of the through groove away from the second spring-pressing section, and the other end extends into the gap groove and can apply an elastic force to the card holder along the path from the first spring-pressing section to the second spring-pressing section.

[0014] In one embodiment, the first elastic segment and the second elastic segment are arranged at an angle, and the second elastic segment is bent relative to the first elastic segment toward the direction closer to the cover.

[0015] In one embodiment, the first spring-loaded section and the second spring-loaded section are arranged in a straight line.

[0016] In one embodiment, the flip cover structure further includes a first limiting plate and a second limiting plate disposed opposite to each other. The first limiting plate and the second limiting plate are respectively connected to the mounting base, and the first limiting plate and the second limiting plate are respectively limited on both sides of the spring-loaded member along its own width direction.

[0017] In one embodiment, the mating section is provided with an eccentric block, and the mating section is spring-loaded into contact with the eccentric block and the spring-loaded member. The adjacent sides of the eccentric block, which are set at an acute angle, respectively form a first contact portion and a second contact portion. The straight-line distance A from the first contact portion to the rotation axis, the straight-line distance B from the second contact portion to the rotation axis, and the straight-line distance C from the intersection of the first contact portion and the second contact portion to the rotation axis satisfy C>A and C>B.

[0018] Compared with the prior art, the state of the cover in this application can be maintained by simply restricting the rotation of different sides of the cover through the spring-loaded component, thereby greatly simplifying the complexity of the flip cover structure. This not only facilitates the installation of the flip cover structure, but also reduces the production cost of the flip cover structure.

[0019] Furthermore, the first and second spring-loaded sections are approximately distributed on the same straight line, which helps to reduce the thickness of the spring-loaded component, thereby reducing the volume of the spring-loaded component and the required installation space.

Detailed Implementation

[0031] Typically, flip covers need to maintain both open and closed states. Generally, this is achieved using a spring mechanism combined with a snap-fit ​​structure. Specifically, when the flip cover is closed, the snap-fit ​​structure holds it in place; when the flip cover is open, the spring mechanism holds it in place.

[0032] However, this design involves many components, making the overall structure of the flip cover more complex. This not only makes the installation of the flip cover more difficult, but also increases the production cost of the flip cover.

[0033] Please see Figures 1-9 To address the issue of the complex overall structure of existing flip covers, this application provides a flip cover structure comprising a cover body 100, a mounting base 200, a rotating shaft 300, and a spring-loaded component 400. The cover body 100 is rotatably connected to the mounting base 200 via the rotating shaft 300. The mounting base 200 is provided with a limiting groove 210 to allow the cover body 100 to be positioned within the limiting groove 210. This not only improves aesthetics but also prevents the cover body 100 from moving, thereby increasing sealing performance.

[0034] The two ends of the cover 100 rotating around the rotation axis 300 are defined as the cover plate section 110 and the mating section 120, respectively. One end of the spring-loaded component 400 is connected to the mounting base 200, and the other end is spring-loaded and mated with the mating section 120.

[0035] It should be noted that the rotating shaft 300 can be segmented, located at both ends of the cover 100 along the width direction and rotatably connected to the mounting base 200. The rotating shaft 300 can also be a single piece, extending from one end of the cover 100 to the other along the width direction of the cover 100. The rotating shaft 300 can also be single-sided, that is, located on one side of the cover 100 along its own width direction.

[0036] Furthermore, the rotating shaft 300 can be set independently, or it can be fixed to either the cover 100 or the mounting base 200.

[0037] Furthermore, it should be noted that, in order to reduce costs, the spring-loaded component 400 is disposed at one end of the cover 100 along its own width direction. Of course, in order to provide a larger and more stable spring force, there can be multiple spring-loaded components 400, which are disposed at both ends of the cover 100 along its own width direction.

[0038] Specifically, the spring-loaded component 400 can be made of metal, elastic plastic, thermoplastic polyurethane rubber, etc., which will not be listed here.

[0039] In one embodiment, the spring-loaded element 400 is in the shape of a strip or a sheet.

[0040] Compared to the U-shaped structure, the long strip or sheet-like structure can greatly reduce the height space required to install the spring-loaded component 400, thereby improving the adaptability of the spring-loaded component 400 to different flip structures.

[0041] In one embodiment, such as Figures 6-9 As shown, the spring-loaded component 400 includes a first spring-loaded section 410 and a second spring-loaded section 420. The spring-loaded component 400 is installed on the mounting base 200 through the first spring-loaded section 410. One end of the second spring-loaded section 420 is connected to the first spring-loaded section 410, and the other end is spring-loaded and engaged with the mating section 120.

[0042] It should be noted that the first spring-loaded section 410 and the second spring-loaded section 420 can be integrally formed, or they can be welded, snap-fitted, glued or screwed together.

[0043] This design helps reduce the machining difficulty of the spring-loaded component 400.

[0044] Furthermore, in one embodiment, the first spring-loaded section 410 and the second spring-loaded section 420 are arranged along the length of the mounting base 200.

[0045] With this configuration, the first spring-loaded section 410 and the second spring-loaded section 420 are approximately distributed on the same straight line, which helps to reduce the thickness of the spring-loaded component 400, thereby reducing the volume of the spring-loaded component 400 and the required installation space.

[0046] Furthermore, in one embodiment, as Figures 6-9 As shown, the first spring-loaded section 410 and the second spring-loaded section 420 are arranged at an angle, and the second spring-loaded section 420 is bent relative to the first spring-loaded section 410 toward the direction closer to the cover 100.

[0047] Since the second spring-loaded section 420 is bent toward the direction close to the cover 100, the V-shaped opening formed by the angle between the first spring-loaded section 410 and the second spring-loaded section 420 faces one side of the cover 100. This helps to increase the elastic coefficient of the spring-loaded member 400, thereby increasing the spring force of the spring-loaded member 400 on the mating section 120.

[0048] However, this is not the only embodiment. In other embodiments, the first spring-loaded section 410 and the second spring-loaded section 420 may also be arranged in a straight line.

[0049] Furthermore, in one embodiment, the included angle between the first spring-loaded section 410 and the second spring-loaded section 420 is greater than or equal to 150 degrees and less than 180 degrees.

[0050] In one embodiment, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, the flip structure also includes a locking platform 500. One end of the locking platform 500 is connected to the mounting base 200, and the other end extends toward the direction close to the first spring-loaded section 410. A locking groove 510 is provided on one side of the locking platform 500. A through groove 411 is provided on the first spring-loaded section 410. The through groove 411 is fitted around the periphery of the locking platform 500, and the side of the through groove 411 near the second spring-loaded section 420 is locked in the locking groove 510.

[0051] It should be noted that the side portion of the through groove 411 near the second spring-loaded section 420 refers to the solid portion between the through groove 411 and the second spring-loaded section 420, and this solid portion belongs to the first spring-loaded section 410.

[0052] Specifically, the card holder 500 can be columnar or hook-shaped. When the card holder 500 is columnar, the card slot 510 is provided on the side wall of the card holder 500. When the card holder 500 is hook-shaped, the card slot 510 is formed at the hook tip.

[0053] When the second spring-loaded section 420 is subjected to a pressing force applied by the mating section 120 in the direction away from the mounting base 200, the side portion of the through groove 411 away from the second spring-loaded section 420 can be pressed and abutted against the mounting base 200.

[0054] It should be noted that the side portion of the through groove 411 away from the second spring-loaded section 420 refers to the solid portion between the through groove 411 and the end of the first spring-loaded section 410 away from the second spring-loaded section 420, and this solid portion belongs to the first spring-loaded section 410.

[0055] Thus, the spring-loaded component 400, mounting base 200, locking platform 500, and mating section 120 cooperate to form a lever structure. The locking groove 510 and through groove 411 of the locking platform 500, near the side of the second spring-loaded section 420, form the fulcrum of the lever structure. The side of the through groove 411 away from the second spring-loaded section 420 forms one end of the lever structure, and the portion where the second spring-loaded section 420 contacts the mating section 120 forms the other end of the lever structure. When the second spring-loaded section 420 is subjected to a compressive force applied by the mating section 120 in a direction away from the mounting base 200, the lever structure generates a torque around the fulcrum, causing the side of the through groove 411 away from the second spring-loaded section 420 to press against and abut against the mounting base 200.

[0056] Since forces are reciprocal, the mounting base 200 can apply a pressing force to the mating section 120 that is equal in magnitude and opposite in direction to the squeezing force through the lever structure. Furthermore, since the spring-loaded component 400 can generate elastic deformation, the pressing force on the mating section 120 directly originates from the elastic deformation of the second spring-loaded section 420.

[0057] This design ensures that the pressure applied to the contact point remains stable and reduces the assembly difficulty of the spring-loaded component 400, the mounting base 200, and the cover 100.

[0058] Furthermore, in one embodiment, as Figure 5 As shown, there are multiple slots 510, and the multiple slots 510 are spaced apart along the direction from the mounting base 200 to the spring-loaded member 400.

[0059] Obviously, when the through groove 411 is engaged with the side of the second spring-loaded section 420 near the mounting base 200, the second spring-loaded section 420 is closer to the mating section 120. At this time, when the mating section 120 rotates by the same angle, the deformation of the second spring-loaded section 420 is greater, that is, the final mating section 120 is subjected to greater spring force from the spring-loaded component 400.

[0060] Conversely, when the through groove 411 is engaged with the side of the second spring-loaded section 420 in the slot 510 away from the mounting base 200, the second spring-loaded section 420 is further away from the mating section 120. At this time, when the mating section 120 rotates by the same angle, the deformation of the second spring-loaded section 420 is smaller, that is, the spring force of the mating section 120 on the spring-loaded component 400 is smaller.

[0061] This design allows for flexible adjustment of the spring force exerted by the spring-loaded component 400 on the cover 100.

[0062] Furthermore, in one embodiment, as Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, the flip structure also includes a support protrusion 600, which is located on the side of the card plate 500 away from the second spring-loaded section 420 and connected to the mounting base 200. The second spring-loaded section 420 can drive the through groove 411 away from the side of the second spring-loaded section 420 to press and abut against the support protrusion 600.

[0063] Specifically, the support protrusion 600 can be in various shapes such as square, frustum, or cylinder, which will not be listed here.

[0064] By setting the support protrusion 600, on the one hand, the support strength of the mounting base 200 can be improved to prevent deformation of the mounting base 200. On the other hand, the side of the through groove 411 away from the second spring-loaded section 420 can be raised, thereby making the second spring-loaded section 420 closer to the mating section 120 through the lever structure, thereby increasing the deformation of the second spring-loaded section 420 and increasing the spring force on the mating section 120, so that the state of the cover 100 remains more stable.

[0065] Furthermore, in one embodiment, as Figure 2 , Figure 4 , Figure 5 and Figure 9 As shown, the card holder 500 and the support protrusion 600 are spaced apart to form a spacer groove 610. The flip structure also includes a spring tongue 700. One end of the spring tongue 700 is connected to the side of the through groove 411 away from the second spring pressing section 420, and the other end extends into the spacer groove 610 and can apply an elastic force to the card holder 500 along the path from the first spring pressing section 410 to the second spring pressing section 420.

[0066] Thus, the locking plate 500 can apply a reaction force to the tongue portion 700 extending from the second pressing section 420 to the first pressing section 410. At this time, the side portion of the through groove 411 near the second pressing section 420 can apply a pressing force to the locking groove 510 extending from the second pressing section 420 to the first pressing section 410, thereby preventing the pressing member 400 from disengaging from the locking groove 510.

[0067] Specifically, in one embodiment, the spring tongue 700 is a U-shaped spring sheet, and the two ends of the U-shaped spring sheet are pressed together in a direction that brings them closer to each other, so that the two ends of the spring tongue 700 generate an elastic force that moves them away from each other.

[0068] However, it is not limited to this. In other embodiments, the snap tongue 700 may also be spring-shaped.

[0069] In one embodiment, such as Figure 7 and Figure 9 As shown, the flip structure also includes a first limiting plate 810 and a second limiting plate 820 disposed opposite to each other. The first limiting plate 810 and the second limiting plate 820 are respectively connected to the mounting base 200, and the first limiting plate 810 and the second limiting plate 820 are respectively limited on both sides of the width direction of the first spring-loaded section 410 to prevent the first spring-loaded section 410 from sliding laterally.

[0070] It should be noted that the direction from the first spring-pressing section 410 to the second spring-pressing section 420 is the length direction of the spring-pressing member 400, and the direction from the mounting base 200 to the spring-pressing member 400 is the thickness direction of the spring-pressing member 400.

[0071] like Figure 2 and Figure 4 As shown, the mating section 120 has a first contact portion 121 and a second contact portion 122 that are disposed opposite to each other.

[0072] It should be noted that the first contact portion 121 and the second contact portion 122 can be point-like areas that contact the spring-loaded member 400, or they can be line-like areas or surface-like areas that contact the spring-loaded member 400, and no specific limitation is made here.

[0073] like Figure 1 and Figure 2 As shown, when the cover plate segment 110 drives the mating segment 120 to rotate around the rotation axis 300 along the first rotation direction, and the first contact portion 121 contacts the spring pressing member 400, the cover plate segment 110 is in an outward flipped state and the mounting base 200 is in an exposed state. Furthermore, the spring pressing member 400 can prevent the cover body 100 from rotating along the second rotation direction.

[0074] It should be noted that the spring-loaded element 400 can prevent the cover 100 from rotating along the second direction of rotation in the following two embodiments.

[0075] In the first embodiment, when the first contact portion 121 contacts the spring-loaded member 400, the spring-loaded member 400 can drive the mating section 120 to rotate around the rotation axis 300 along the first rotation direction or have a tendency to rotate along the first rotation direction. Furthermore, the spring-loaded member 400 can apply a first spring force to the first contact portion 121 so that the mating section 120 can drive the cover section 110 to press and cover the mounting base 200. At this time, the flip cover structure is in the closed state, that is, the cover section 110 can cover the mounting base 200 and maintain the pressed state, preventing the cover section 110 from moving away from the mounting base 200, thereby preventing the cover 100 from loosening.

[0076] In the second embodiment, when the first contact portion 121 contacts the spring-loaded member 400, the surface of the spring-loaded member 400 near the first contact portion 121 can fit against the corresponding surface of the first contact portion 121, so that the cover plate segment 110 remains in the state of covering the mounting base 200. At this time, the rotation of the cover body 100 can be restricted by the surface-to-surface contact.

[0077] It should be noted that the surface of the spring-loaded component 400 near the first contact portion 121 and the surface corresponding to the first contact portion 121 can be a plane, a curved surface, or other irregularly shaped surfaces, which will not be listed here.

[0078] like Figure 3 and Figure 4 As shown, when the cover plate segment (110) drives the mating segment (120) to rotate around the rotation axis (300) along the second rotation direction, and the second contact portion (122) contacts the spring-loaded member (400), the cover plate segment (110) can cover the mounting base (200); and the spring-loaded member (400) can prevent the cover body (100) from rotating along the first rotation direction.

[0079] It should be noted that the spring-loaded element 400 can prevent the cover 100 from rotating along the first rotation direction in the following two embodiments.

[0080] In Embodiment 1, when the second contact portion 122 contacts the spring-loaded member 400, the spring-loaded member 400 can drive the mating section 120 to rotate around the rotation axis 300 along the second rotation direction or have a tendency to rotate along the second rotation direction through the second contact portion 122. Furthermore, the spring-loaded member 400 can apply a second spring force to the second contact portion 122 so that the mating section 120 can drive the cover section 110 to flip outward and open the mounting base 200. At this time, the flip-top structure is in the open state, that is, the cover section 110 can open the mounting base 200 and remain in the flipped state, preventing the cover section 110 from moving towards the mounting base 200, thereby avoiding the cover 100 from blocking the mounting base 200 and affecting the retrieval and placement of items inside the mounting base 200.

[0081] In the second embodiment, when the second contact portion 122 contacts the spring-loaded member 400, the surface of the spring-loaded member 400 near the second contact portion 122 can adhere to the surface corresponding to the second contact portion 122, so that the cover plate segment 110 remains in an outward-facing state and the mounting base 200 is exposed. At this time, the rotation of the cover body 100 can be restricted by the surface-to-surface contact.

[0082] It should be noted that the surface of the spring-loaded component 400 near the second contact portion 122 and the surface corresponding to the second contact portion 122 can be a plane, a curved surface, or other irregularly shaped surfaces, which will not be listed here.

[0083] It should be noted that the first and second rotations are opposite. That is, when the first rotation is clockwise, the second rotation is counterclockwise, and vice versa.

[0084] Compared with the prior art, in this application, the state of the cover 100 can be maintained simply by restricting the rotation of different sides of the cover 100 through the spring-loaded member 400, thereby greatly simplifying the complexity of the flip structure. This not only facilitates the installation of the flip structure but also reduces the production cost of the flip structure.

[0085] It is important to note that, such as Figure 1 and Figure 3 As shown, the end of the cover plate section 110 away from the mating section 120 is provided with an operating groove 111, so that external personnel can hook the cover body 100 through the operating groove 111 and drive it to rotate.

[0086] In one embodiment, such as Figure 2 , Figure 4 and Figure 8 As shown, the mating section 120 is provided with an eccentric block 123. The mating section 120 is spring-loaded into contact with the spring-loaded member 400 through the eccentric block 123. The adjacent sides of the eccentric block 123, which are arranged at an acute angle, respectively form the first contact portion 121 and the second contact portion 122. Furthermore, the straight-line distance A between the first contact portion 121 and the rotating shaft 300, the straight-line distance B between the second contact portion 122 and the rotating shaft 300, and the straight-line distance C between the intersection of the first contact portion 121 and the second contact portion 122 and the rotating shaft 300 satisfy C>A and C>B.

[0087] Since C>A and C>B, according to the principle of leverage, regardless of whether the spring-loaded component 400 is pressed against the first contact part 121 or the second contact part 122, the cover 100 cannot rotate in the opposite direction without the action of external force, thereby greatly enhancing the pressing stability of the spring-loaded component 400.

[0088] The technical features of the above embodiments can be combined in any way.
