Description

Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to a slide groove structure, a rotating shaft mechanism and an electronic device. Background Art

[0002] With the development of terminal technology, the display screen size of electronic devices such as mobile phones is getting larger and larger. In order to take into account the user's portability needs while increasing the display screen size, folding screen devices are gradually entering the user's usage scenarios. The folding screen device includes a flexible screen, a first body, a second body and a hinge mechanism. The two sides of the hinge mechanism are respectively connected to the first body and the second body, and the flexible screen covers the first body, the second body and the hinge mechanism.

[0003] The hinge mechanism is usually a structure combining a slider and a slide groove, and the slider is embedded in the slide groove. By sliding the slider in the slide groove, the hinge mechanism drives the angle between the first body and the second body to change, thereby realizing the folding or unfolding of the folding screen device.

[0004] However, the slider and the slide groove are mostly matched in all aspects, and usually the matching cannot be achieved perfectly, which will cause the flexible screen to swing up and down, resulting in the appearance of a virtual angle, affecting the user's opening and closing experience. Summary of the invention

[0005] The present application provides a slide groove structure, a rotating shaft mechanism and an electronic device to solve the problem that the existing slider and the slide groove are prone to produce a virtual angle when they are matched.

[0006] In a first aspect, the present application provides a slide groove structure, comprising: a bottom plate and an elastic member. The bottom plate comprises a first surface, a first wedge block and a second wedge block, the first wedge block is located on the first surface, the second wedge block is buckled on the first wedge block, one end of the second wedge block protrudes relative to the first wedge block, so that a slide groove is formed by the second wedge block, the first wedge block and the first surface; the elastic member is located between the first wedge block and the second wedge block, and the elastic member is configured to adjust the height of the slide groove.

[0007] In the slide groove structure provided in the embodiment of the present application, an elastic member is arranged between the first wedge block and the second wedge block. By squeezing the second wedge block, the elastic member is deformed and the height of the slide groove is precisely adjusted. In this way, when the slider slides in the slide groove, the gap between the outer surface of the slider and the inner surface of the slide groove can be reduced, thereby preventing the slider and the slide groove from getting stuck during the folding or unfolding process and avoiding the virtual angle, thereby improving the rotation accuracy of the shaft mechanism and improving the opening and closing experience of the user.

[0008] In some implementations, the second surface of the first wedge block includes at least one group of first ridge groups, and the second surface faces the second wedge block; the first ridge group includes a first ridge and a second ridge, and the first ridge and the second ridge are arranged at intervals along a first direction to form a first groove; wherein the first direction is perpendicular to the length direction of the first ridge; and the elastic member is located in the first groove. In this way, the first wedge block and the second wedge block are embedded by using each group of first ridge groups, so as to improve the reliability of the embedding of the first wedge block and the second wedge block, and avoid the first wedge block and the second wedge block from being dislocated or moved except along the sliding direction.

[0009] In some implementations, the first ridge includes a first sub-ridge and a second sub-ridge, the first sub-ridge and the second sub-ridge are spaced apart along a second direction, and the second direction is the length direction of the first ridge; the second ridge includes a third sub-ridge and a fourth sub-ridge, the third sub-ridge and the fourth sub-ridge are spaced apart along the second direction; the spacing position of the first sub-ridge and the second sub-ridge is opposite to the spacing position of the third sub-ridge and the fourth sub-ridge. In this way, the sub-ridges are distributed in a rectangular array, which can improve the reliability of the first wedge block and the second wedge block being embedded.

[0010] In some implementations, the method further includes: a first limit block and a second limit block; the first limit block is located between the first sub-convex ridge and the second sub-convex ridge, and the second limit block is located between the third sub-convex ridge and the fourth sub-convex ridge; and the elastic member is located between the first limit block and the second limit block. In this way, the elastic member is clamped by the first limit block and the second limit block. When the first wedge block and the second wedge block are combined, the second wedge block applies a force to the first limit block and the second limit block, and then the first limit block and the second limit block apply a force to the elastic member, and the deformation of the elastic member adjusts the engagement depth of the second wedge block and the first wedge block, thereby adjusting the height of the slide groove.

[0011] In some implementations, the first outer surface of the first stopper is inclined relative to the first surface and protrudes from the outer surface of the first sub-convex ridge and the outer surface of the second sub-convex ridge; the second outer surface of the second stopper is inclined relative to the first surface and protrudes from the outer surface of the third sub-convex ridge and the outer surface of the fourth sub-convex ridge; the first outer surface and the second outer surface form an angle toward the bottom plate. In this way, the first stopper and the second stopper can be in contact with the inclined surface of the second wedge block, so as to adjust the engagement depth of the second wedge block and the first wedge block through the deformation of the elastic member, thereby adjusting the height of the slide groove.

[0012] In some implementations, the third surface of the second wedge block includes at least one second ridge group, and the third surface faces the first wedge block; the second ridge group includes a third ridge and a fourth ridge, and the third ridge and the fourth ridge are arranged at intervals along the first direction to form a second groove; the second groove is configured to accommodate the first ridge group when the second wedge block is buckled on the first wedge block. In this way, the reliability of the engagement of the first wedge block and the second wedge block can be improved, and then the first limit block and the second limit block are applied to cause the elastic member to deform, so as to adjust the engagement depth of the second wedge block and the first wedge block, and then adjust the height of the slide groove.

[0013] In some implementations, the second groove includes a first inner surface and a second inner surface that are opposite to each other; the first inner surface and the second inner surface are both inclined relative to the third surface and form an angle toward the first surface. In this way, the second groove can be matched with the first convex ridge and the second convex ridge in a surface-to-surface manner.

[0014] In some implementations, the first inner surface includes a first protrusion, the second inner surface includes a second protrusion, and the first protrusion is opposite to the second protrusion; when the second wedge block is buckled on the first wedge block, the first protrusion is configured to abut against the first outer surface of the first limit block and apply a force to the first limit block, and the second protrusion is configured to abut against the second outer surface of the second limit block and apply a force to the second limit block; the first limit block and the second limit block are configured to move toward each other under the force, so that the elastic member is deformed to adjust the distance between the third surface of the second wedge block and the first surface, thereby adjusting the height of the slide. In this way, the relative movement of the second wedge block and the first wedge block and the deformation of the elastic member can be used to adjust the height of the slide, so as to achieve zero matching between the slide and the slider and avoid the appearance of a virtual angle.

[0015] In some implementations, the method further comprises: at least one locking structure; the locking structure is configured to lock the first wedge block and the second wedge block after the slide groove is adjusted to have a preset height. In this way, the relative positions of the first wedge block and the second wedge block can be fixed, so that during use, the height of the slide groove is always the preset height.

[0037] The technical solutions in the embodiments of the present application will be described clearly below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, other embodiments obtained by ordinary technicians in this field without making creative work all belong to the protection scope of the present application.

[0038] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0039] In addition, in the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0040] The electronic device described in the embodiments of the present application includes but is not limited to a mobile phone, a mobile phone accessory, a folding screen mobile phone, a laptop computer, a laptop computer accessory, a tablet computer, a tablet computer accessory, a laptop computer, a personal digital assistant or a wearable device, etc. The following description is based on the electronic device being a folding screen mobile phone.

[0041] Figure 1 It is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application.

[0042] like Figure 1 As shown, the electronic device may include a first body 10, a second body 20, a display screen 30 and a hinge assembly 40, wherein: Figure 1 The dotted line in the figure schematically shows the area of ​​the hinge assembly 40. The first body 10 and the second body 20 are arranged on both sides of the axis direction of the hinge assembly 40. The first body 10 and the second body 20 are respectively connected to the hinge assembly 40, and the hinge assembly 40 can be rotated to reduce the angle between the first body 10 and the second body 20 until the electronic device is in a folded state (not shown in the figure); or increase the angle between the first body 10 and the second body 20 until the electronic device is in an unfolded state (as shown in the figure). Figure 1 The electronic device may also be unfolded or folded to an intermediate state, and the intermediate state may be any state between the unfolded state and the folded state.

[0043] The display screen 30 covers the first body 10, the second body 20 and the hinge assembly 40, and is connected to the first body 10 and the second body 20 respectively. The rotation of the first body 10 and the second body 20 can drive the display screen 30 to bend or unfold. Exemplarily, the display screen 30 can be a bendable flexible screen, and the display screen 30 has a bending area, so that the display screen 30 can be bent in the bending area as the hinge assembly 40 rotates.

[0044] The display screen 30 moves with the electronic device, and the state of the electronic device is the same as the state of the hinge assembly 40. When the electronic device is in the unfolded state, the hinge assembly 40 is also in the unfolded state. In the unfolded state, the first body 10 and the second body 20 are parallelly distributed on both sides of the hinge assembly 40, and the display screen 30 is laid flat on the hinge assembly 40 in the unfolded state. The display screen 30 is displayed in full screen, so that the electronic device has a larger display area to improve the user's viewing and operating experience. When the electronic device is in the folded state, the hinge assembly 40 is also in the folded state (such as Figure 2 ). In the folded state, the first body 10 and the second body 20 are relatively distributed on both sides of the hinge assembly 40, and the hinge assembly 40 presses the display screen 30 into a water drop shape. When the electronic device is in the folded state, the plane size of the electronic device is small, which is convenient for users to carry and store. When the electronic device is in the intermediate state, the hinge assembly 40 is also in the intermediate state.

[0045] Depending on the rotation direction of the first body 10 and the second body 20, the flexible screen may be hidden inside the body when the electronic device is in a folded state, or it may be wrapped around the outside of the body. Among them, when the first body 10 and the second body 20 are folded toward the front of the flexible screen, the flexible screen is hidden inside the body when the electronic device is in a folded state, and this electronic device can be called an inner folding screen electronic device, such as an inner folding screen mobile phone; when the first body 10 and the second body 20 are folded toward the back of the flexible screen, the flexible screen is wrapped around the outside of the body when the electronic device is in a folded state, and this electronic device can be called an outer folding screen electronic device, such as an outer folding screen mobile phone.

[0046] It should be noted that electronic components such as circuit boards, camera modules, speaker modules and batteries may be disposed in the first body 10 and the second body 20 , which are not listed one by one here.

[0047] To facilitate the explanation of the positions of various components in an electronic device, the embodiment of the present application exemplarily establishes a three-dimensional coordinate system based on the electronic device, wherein the x-axis direction is the width direction of the electronic device, the y-axis direction is the length direction of the electronic device, and the z-axis direction is the thickness direction of the electronic device.

[0048] Figure 2 The present invention is a structural schematic diagram of a rotating shaft assembly.

[0049] like Figure 2 As shown, the shaft assembly 40 includes a shaft base 41, a left door panel 42, a right door panel 43, a left connecting block 44, a right connecting block 45, two sets of swing arms 46, two sets of door panel swing arms 47 and two sets of damping swing arms 48. It should be noted that Figure 2 Only part of the structure of the rotating shaft assembly 40 is shown, and other structures of the rotating shaft assembly 40 are not shown. A group of swing arms 46 includes two swing arms 46, a group of door panel swing arms 47 includes two door panel swing arms 47, and a group of damping swing arms 48 includes two damping swing arms 48.

[0050] The length direction of the rotating shaft base 41 is the axis direction Z0 of the rotating shaft assembly 40, and the axis direction Z0 is parallel to the y-axis direction. The left door panel 42 and the right door panel 43 are located on opposite sides of the rotating shaft base 41 along the axis direction Z0, and the left connecting block 44 and the right connecting block 45 are located on opposite sides of the rotating shaft base 41 along the axis direction Z0. The left door panel 42 is connected to the left connecting block 44, and the right door panel 43 is connected to the right connecting block 45. The left connecting block 44 is movably connected to one side of the rotating shaft base 41 through a group of swing arms 46, a group of door panel swing arms 47 and a group of damping swing arms 48, and the right connecting block 45 is movably connected to the other side of the rotating shaft base 41 through another group of swing arms 46, another group of door panel swing arms 47 and another group of damping swing arms 48. Among them, the movable connection can be a rotating connection or a sliding connection.

[0051] Combination Figure 1 and Figure 2 The display screen 30 is covered on the left door panel 42 and the right door panel 43 (hereinafter collectively referred to as the door panels), and the door panels are used to support the display screen 30. The door panels can be fixedly connected to the display screen 30, and the door panels can move with the folding and unfolding of the rotating shaft assembly 40, and can push the display screen 30 to fold or unfold, so as to support the display screen 30 in the unfolded state, and press the display screen 30 into a water drop shape in the folded state. Figure 2 The structure of the rotating shaft assembly 40 is shown in a folded state.

[0052] In order to realize the rotation of the shaft assembly 40, the components in the shaft assembly 40 are usually a structure in which a slider part and a slide groove part are combined, the slider part is embedded in the slide groove part, and the slider part slides in the slide groove part. Exemplarily, the sliding between the door panel and the swing arm part can be realized by combining the slider part and the slide groove part, wherein the door panel is the left door panel 42 or the right door panel 43, and the swing arm part is the swing arm 46, the door panel swing arm 47 or the damping swing arm 48.

[0053] Figure 3A The invention is a structural schematic diagram of the matching structure of a slider part and a slide groove part.

[0054] like Figure 3AAs shown, taking the sliding of the swing arm 46 and the right door panel 43 as an example, one end of the swing arm 46 includes two sliders 461, and the two sliders 461 are spaced apart and located at one end of the swing arm 46 facing the right door panel 43. The right door panel 43 includes two wedge blocks 431, which are spaced apart and correspond to the two sliders 461 one by one.

[0055] Each wedge block 431 includes a slide groove portion 432, and the two slide groove portions 432 correspond to two slider portions 461. The slider portion 461 is embedded in the corresponding slide groove portion 432 and slides in the slide groove portion 432 along the x-axis direction to achieve the sliding of the swing arm 46 relative to the right door panel 43, thereby achieving the rotation of the right door panel 43.

[0056] Figure 3B The present invention is a side view of the matching structure of a slider part and a slide groove part.

[0057] like Figure 3B As shown, the slide groove portion 432 is a frame-shaped structure with one end open, and the slider portion 461 is a polygonal structure. In this way, the slider portion 461 and the slide groove portion 432 are matched in a face-to-face manner.

[0058] In order to ensure the smoothness of the folding screen device during folding or unfolding and avoid jamming during folding or unfolding, the matching of the slider portion 461 and the slide groove portion 432 is usually not zero matching. In other words, there is a gap between the outer surface of the slider portion 461 and the inner surface of the slide groove portion 432.

[0059] During the folding or unfolding of the hinge assembly, the slider portion 461 moves along the z-axis or y-axis direction in the slide groove portion 432. This reduces the rotation accuracy of the hinge assembly 40, and the left door panel 42 and the right door panel 43 cannot rotate along the preset stroke. The abnormal rotation of the left door panel 42 and the right door panel 43 will apply different forces to the display screen 30, causing the display screen 30 to swing up and down, resulting in the appearance of a virtual angle, which affects the user's opening and closing experience.

[0060] In order to avoid the occurrence of virtual angles, an embodiment of the present application provides a slide groove structure, which can adjust the height of the slide groove as needed to achieve zero matching between the slide groove and the slider, avoid excessive gap between the slide groove and the slider, and thus avoid the occurrence of virtual angles.

[0061] The embodiment of the present application is explained by taking the application of the slide groove structure in the pivot mechanism as an example. In the pivot mechanism, the slide groove structure can achieve zero matching between the slider and the slide groove while avoiding jamming during folding or unfolding, thereby improving the rotation accuracy of the pivot mechanism and improving the user's opening and closing experience.

[0062] Figure 4: is a schematic diagram of a shaft mechanism provided in an embodiment of the present application. Figure 4 Shows part of the structure of the rotating shaft mechanism.

[0063] like Figure 4 As shown, in some embodiments, the rotating shaft mechanism may include: a base 510 , a door panel 520 , a swing arm, a synchronization mechanism 550 and a damping mechanism 560 .

[0064] There are two door panels 520, which are located on opposite sides of the base 510. The two door panels 520 correspond to two swing arms one by one, and the swing arms may include a main swing arm 530 and an auxiliary swing arm 540. There are two main swing arms 530 and two auxiliary swing arms 540, which are located on opposite sides of the base 510, and two auxiliary swing arms 540 are located on opposite sides of the base 510.

[0065] The door panel 520 includes a plurality of slide groove structures, and each door panel 520 is slidingly connected to a main swing arm 530 and an auxiliary swing arm 540 through a corresponding slide groove structure, so that each door panel 520 is rotationally connected to the base 510 through a main swing arm 530 and an auxiliary swing arm 540.

[0066] The synchronization mechanism 550 and the damping mechanism 560 are located between the two door panels 520 and connected to the two door panels 520. One end of the synchronization mechanism 550 is fixed to the base 510, and the other end is connected to the damping mechanism 560. The synchronization mechanism 550 is used to achieve synchronous rotation of the two door panels 520, and the damping mechanism 560 is used to provide damping feedback to the user when the door panels 520 rotate.

[0067] Figure 5 : is a schematic diagram of the structure of the chute structure provided in the embodiment of the present application. Figure 5 Show Figure 4 The local structure of region A.

[0068] like Figure 5 As shown, in some embodiments, the slide groove structure may include: a bottom plate 100 and an elastic member 200 .

[0069] Combination Figure 4 and Figure 5 When the slide groove structure is applied in a rotating shaft mechanism, the bottom plate 100 can be a door plate 520 in the rotating shaft mechanism.

[0070] The bottom plate 100 includes a first surface 101, a first wedge block 102 and a second wedge block 103. Figure 1 and Figure 2 , the first surface 101 faces away from the display screen 30 .

[0071] The first wedge block 102 is located on the first surface 101 , and the first wedge block 102 protrudes relative to the first surface 101 of the bottom plate 100 . The first wedge block 102 can be integrally formed with the bottom plate 100 . For example, the first wedge block 102 can be integrally formed with the door panel 520 .

[0072] The second wedge block 103 is buckled on the first wedge block 102, and one end of the second wedge block 103 protrudes relative to the first wedge block 102. The second wedge block 103 is staggered relative to the first wedge block 102 along the y-axis direction, so that the second wedge block 103, the first wedge block 102 and the first surface 101 of the bottom plate 100 form a slide groove 104.

[0073] The length direction of the slide groove 104 is the x-axis direction, and the slide groove 104 provides a sliding direction along the x-axis direction. The slide groove 104 can be a semi-enclosed frame structure to facilitate the insertion of the slider of the swing arm.

[0074] One end of the swing arm is rotatably connected to the base 510 , and the other end includes a slider. The slider of the swing arm is embedded in the slide groove 104 on the door panel assembly opposite thereto, so as to realize the rotation of the door panel 520 relative to the base 510 .

[0075] The following is an exemplary description of the swing arm as a main swing arm 530, where the end of the main swing arm 530 facing away from the base 510 includes a slider 531. The slider 531 of the main swing arm 530 is embedded in the slide groove 104 to achieve sliding between the bottom plate 100 and the main swing arm 530, thereby achieving rotation of the bottom plate 100 relative to the base 510.

[0076] Figure 6 yes Figure 4 Schematic diagram of the local structure of the BB section. Figure 6 A schematic cross-sectional view of the slideway structure is shown.

[0077] like Figure 6 As shown, in some embodiments, the elastic member 200 is located between the first wedge block 102 and the second wedge block 103, and the elastic member 200 is configured to adjust the height H of the slide groove 104. 104 .

[0078] The elastic member 200 may be made of a material having elastic recovery capability, for example, the elastic member 200 may be made of silicone.

[0079] When the second wedge block 103 is mounted on the first wedge block 102, the distance between the second wedge block 103 and the first surface 101 of the bottom plate 100 can be adjusted by squeezing the elastic member 200, thereby adjusting the height H of the slide groove 104. 104 .

[0080] The slide groove structure provided in the embodiment of the present application is to disassemble the original wedge block on the door panel 520 into a first wedge block 102 and a second wedge block 103, and an elastic member 200 is arranged between the first wedge block 102 and the second wedge block 103. By squeezing the second wedge block 103, the elastic member 200 is deformed to accurately adjust the height H of the slide groove 104. 104 In this way, when the slider 531 slides in the slide groove 104, the gap between the outer surface of the slider 531 and the inner surface of the slide groove 104 can be reduced, or even zero, so that the slider 531 and the slide groove 104 can avoid being stuck during folding or unfolding, and avoid the virtual angle, thereby improving the rotation accuracy of the shaft mechanism and improving the user's opening and closing experience.

[0081] Figure 7 yes Figure 4 Partial side view of area A in the middle. Figure 7 A side view of the chute structure is shown.

[0082] like Figure 7 As shown, in some embodiments, to improve the balance and stability of the rotation, the main swing arm 530 may include two sliders 531, and the two sliders 531 are spaced apart along the y-axis direction and located at one end of the main swing arm 530 away from the base 510.

[0083] The first surface 101 of the bottom plate 100 includes two first wedge blocks 102, which are spaced apart along the y-axis direction. Correspondingly, the number of second wedge blocks 103 is also two, and the two second wedge blocks 103 are respectively buckled on the corresponding first wedge blocks 102 to form two slide grooves 104. The opening directions of the two slide grooves 104 are opposite, and the sliding directions provided by the two slide grooves 104 are both along the x-axis direction.

[0084] The two sliders 531 correspond to the two slide grooves 104 one by one, and each slider 531 is embedded in the slide groove 104 opposite thereto. The sliders 531 slide in the slide grooves 104 opposite thereto to achieve stable rotation between the main swing arm 530 and the base plate 100.

[0085] An elastic member 200 is respectively disposed between each group of corresponding first wedge blocks 102 and second wedge blocks 103 , and each elastic member 200 is used to adjust the height of the slide groove 104 formed by each group of corresponding first wedge blocks 102 and second wedge blocks 103 .

[0086] It should be noted that the structures of the two groups of first wedge blocks 102 and second wedge blocks 103, the structure of the slide groove 104 formed therefrom, and the method of adjusting the height of the slide groove 104 are all the same. The following only takes the example of one group of first wedge blocks 102 and second wedge blocks 103 forming the slide groove 104 and using the corresponding elastic member 200 to adjust the height of the slide groove 104 as an example for illustrative description.

[0087] Figure 8 It is a schematic diagram of the structure of the first wedge block provided in an embodiment of the present application.

[0088] like Figure 8 As shown, in some embodiments, the first wedge block 102 includes a second surface 1021 , the second surface 1021 faces away from the first surface 101 of the base plate 100 , the second surface 1021 is parallel to the first surface 101 , and the second surface 1021 faces the second wedge block 103 .

[0089] The second surface 1021 may include at least one group of first ridge groups, and each group of first ridge groups is spaced apart on the second surface 1021. Each group of first ridge groups is used to achieve the engagement of the first wedge block 102 and the second wedge block 103, so as to improve the reliability of the engagement of the first wedge block 102 and the second wedge block 103, and avoid misalignment or movement between the first wedge block 102 and the second wedge block 103 except along the sliding direction.

[0090] The first ridge group may include a first ridge 1022 and a second ridge 1023. The first ridge 1022 and the second ridge 1023 are spaced apart along a first direction to form a first groove 1024, and the first groove 1024 is surrounded by two opposite surfaces of the first ridge 1022 and the second ridge 1023 and the second surface 1021. The first direction is perpendicular to the length direction of the first ridge 1022, the first direction is perpendicular to the x-axis direction, and the first direction is parallel to the y-axis direction.

[0091] Fig. 9 This is the matching structure of the first wedge block and the elastic member provided in the embodiment of the present application.

[0093] In this way, the elastic member 200 is fixed by the first convex ridge 1022 and the second convex ridge 1023 , so that when the first wedge block 102 and the second wedge block 103 are combined, the combination reliability can be improved and a force can be applied to the elastic member 200 to adjust the height of the slide groove 104 .

[0094] See again Figure 8In some embodiments, the first ridge 1022 may include a first sub-ridge 10221 and a second sub-ridge 10222, and the first sub-ridge 10221 and the second sub-ridge 10222 are spaced apart along the second direction. The second direction is the length direction of the first ridge 1022, the second direction is parallel to the x-axis direction, and the second direction is parallel to the sliding direction provided by the slide groove 104.

[0095] The second ridge 1023 includes a third sub-ridge 10231 and a fourth sub-ridge 10232 , and the third sub-ridge 10231 and the fourth sub-ridge 10232 are spaced apart from each other along the second direction.

[0096] The first sub-ridge 10221 and the third sub-ridge 10231 are spaced apart along the y-axis direction, and the second sub-ridge 10222 and the fourth sub-ridge 10232 are spaced apart along the y-axis direction. The spacing position between the first sub-ridge 10221 and the second sub-ridge 10222 is opposite to the spacing position between the third sub-ridge 10231 and the fourth sub-ridge 10232. It can be understood that the first sub-ridge 10221, the second sub-ridge 10222, the third sub-ridge 10231 and the fourth sub-ridge 10232 are distributed in a rectangular array.

The first limit block 301 and the second limit block 302 both have a certain strength and hardness to avoid deformation due to extrusion. Exemplarily, the first limit block 301 and the second limit block 302 may be made of metal.

[0098] The first stopper 301 is located between the first sub-ridge 10221 and the second sub-ridge 10222, and the first stopper 301 can move between the first sub-ridge 10221 and the second sub-ridge 10222. The second stopper 302 is located between the third sub-ridge 10231 and the fourth sub-ridge 10232, and the second stopper 302 can move between the third sub-ridge 10231 and the fourth sub-ridge 10232. The elastic member 200 is located between the first stopper 301 and the second stopper 302, and the first stopper 301 and the second stopper 302 can squeeze the elastic member 200 and cause it to deform.

[0099] In this way, the first limit block 301 and the second limit block 302 are located at opposite sides of the elastic member 200 along the y-axis direction, and the first limit block 301 and the second limit block 302 are used to clamp the elastic member 200. When the first wedge block 102 and the second wedge block 103 are combined, the second wedge block 103 applies a force to the first limit block 301 and the second limit block 302, and then the first limit block 301 and the second limit block 302 apply a force to the elastic member 200, and the fitting depth of the second wedge block 103 and the first wedge block 102 is adjusted through the deformation of the elastic member 200, and then the height of the slide groove 104 is adjusted.

[0100] Fig.10 It is a side view of the first wedge block provided in an embodiment of the present application.

[0101] Combination Fig. 9 and Fig.10 As shown, in some embodiments, the first stopper 301 includes a first outer surface 3011, which is the surface of the first stopper 301 facing away from the second stopper 302. The second stopper 302 includes a second outer surface 3021, which is the surface of the second stopper 302 facing away from the first stopper 301.

[0102] The first outer surface 3011 of the first stopper 301 is inclined relative to the first surface 101, and an angle α1 is formed between the first outer surface 3011 and the first surface 101 toward the second stopper 302, and the angle α1 is an acute angle. In the cross section along the y-axis direction, the cross-sectional area of ​​the first stopper 301 is greater than the cross-sectional area of ​​the first convex ridge 1022, the surface of the first stopper 301 facing the second stopper 302 is coplanar with the inner surface of the first convex ridge 1022, and the first outer surface 3011 protrudes from the outer surface 1022a of the first convex ridge 1022.

[0103] The inner surface of the first ridge 1022 is formed by the inner surface of the coplanar first sub-ridge 10221 and the inner surface of the second sub-ridge 10222; the outer surface 1022a of the first ridge 1022 is formed by the coplanar outer surface of the first sub-ridge 10221 and the outer surface of the second sub-ridge 10222. The inner surface of the first sub-ridge 10221 refers to the surface of the first sub-ridge 10221 facing the third sub-ridge 10231, and the outer surface refers to the surface away from the third sub-ridge 10231. The inner surface of the second sub-ridge 10222 refers to the surface of the second sub-ridge 10222 facing the fourth sub-ridge 10232, and the outer surface refers to the surface away from the fourth sub-ridge 10232.

[0104] The second outer surface 3021 of the second stopper 302 is inclined relative to the first surface 101, and an angle α2 is formed between the second outer surface 3021 and the first surface 101 toward the first stopper 301, and the angle α2 is an acute angle. In the cross section along the y-axis direction, the cross-sectional area of ​​the second stopper 302 is greater than the cross-sectional area of ​​the second convex ridge 1023, the surface of the second stopper 302 facing the first stopper 301 is coplanar with the inner surface of the second convex ridge 1023, and the second outer surface 3021 protrudes from the outer surface 1023a of the second convex ridge 1023.

[0105] The inner surface of the second ridge 1023 is formed by the inner surface of the coplanar third sub-ridge 10231 and the inner surface of the fourth sub-ridge 10232; the outer surface of the second ridge 1023 is formed by the coplanar outer surface of the third sub-ridge 10231 and the outer surface of the fourth sub-ridge 10232. The inner surface of the third sub-ridge 10231 refers to the surface of the third sub-ridge 10231 facing the first sub-ridge 10221, and the outer surface refers to the surface away from the first sub-ridge 10221; the inner surface of the fourth sub-ridge 10232 refers to the surface of the fourth sub-ridge 10232 facing the second sub-ridge 10222, and the outer surface refers to the surface away from the second sub-ridge 10222.

[0106] The first outer surface 3011 and the second outer surface 3021 are relatively inclined, and the first outer surface 3011 and the second outer surface 3021 form an angle α3 toward the bottom plate 100, and the angle α3 is an acute angle, a right angle, or an obtuse angle, and the angle α3 is determined according to the degree of inclination of the first outer surface 3011 and the second outer surface 3021. It should be noted that the embodiment of the present application does not limit the inclination angle of the first outer surface 3011 and the second outer surface 3021.

[0107] The outer edge of the first convex rib 1022 and the outer edge of the second convex rib 1023 may enclose a first region, and the cross-sectional shape of the first region is a trapezoid, and may further be an isosceles trapezoid. Exemplarily, the upper width of the first region is W1, and the lower width of the first region is W2, and W1 is smaller than W2. The upper width W1 is the distance between the upper end of the outer surface 1022a of the first convex rib 1022 and the upper end of the outer surface 1023a of the second convex rib 1023, and the lower width W2 is the distance between the bottom end of the outer surface 1022a of the first convex rib 1022 and the bottom end of the outer surface 1023a of the second convex rib 1023.

[0108] The outer edge of the first limit block 301 and the outer edge of the second limit block 302 can enclose a second area, and the cross-sectional shape of the second area is a trapezoid, and can further be an isosceles trapezoid. Exemplarily, the upper width of the second area (not shown in the figure) is greater than the upper width of the first area, which is W1, and the lower width of the second area (not shown in the figure) is greater than the lower width of the first area, which is W2, and the upper width of the second area is less than the lower width of the second area. Among them, the upper width of the second area refers to the distance between the upper end of the first outer surface 3011 and the upper end of the second outer surface 3021, and the lower width of the second area refers to the distance between the bottom end of the first outer surface 3011 and the bottom end of the second outer surface 3021.

[0109] In some embodiments, the elastic member 200 may be bonded to the first limiting block 301 and the second limiting block 302 , and a distance L0 is provided between the bottom end of the elastic member 200 and the bottom surface of the first groove 1024 , that is, the elastic member 200 does not completely fill the first groove 1024 .

[0110] In this way, the space formed by the distance L0 provides space for the deformation of the elastic member 200, so as to facilitate the smooth deformation of the elastic member 200, thereby facilitating the adjustment of the relative heights of the second wedge block 103 and the first wedge block 102, and thereby facilitating the adjustment of the height of the slide slot 104. The deformation of the elastic member 200 in the downward space can prevent the elastic member 200 from deforming upward, thereby preventing the deformed elastic member 200 from abutting against the second wedge block 103 above it, thereby preventing the second wedge block 103 from descending, and thereby preventing the adjustment of the height of the slide slot 104 from being hindered.

[0111] In some embodiments, the second surface 1021 of the first wedge block 102 may further include a third ridge group, the third ridge group including two ridges 1025. The two ridges 1025 are located at opposite ends of the second surface 1021, and the plurality of first ridge groups are located between the two ridges 1025.

[0112] Illustratively, the convex rib 1025 , the first convex rib 1022 , and the second surface 1021 on the left side form a first slot 1026 , and the convex rib 1025 , the second convex rib 1023 , and the second surface 1021 on the right side form a second slot 1027 .

[0113] In this way, by using the two convex edges 1025, the first clamping groove 1026 and the second clamping groove 1027, the relative stability of the first wedge block 102 and the second wedge block 103 can be further improved to avoid misalignment or movement between the two.

[0114] Fig.11 : is a schematic diagram of the structure of the second wedge block provided in the embodiment of the present application. Fig.11 (a) shows the three-dimensional structure of the second wedge block. Fig.11(b) shows Fig.11 A localized magnified structure of region C in (a).

[0115] like Fig.11 As shown in (a), in some embodiments, the second wedge block 103 includes a third surface 1031, combined with Figure 6 and Figure 8 The third surface 1031 faces the first wedge block 102 , and the third surface 1031 is opposite to the second surface 1021 of the first wedge block 102 .

[0116] The third surface 1031 of the second wedge block 103 includes at least one group of second ridge groups, and each group of second ridge groups is spaced apart and located on the third surface 1031. Along the z-axis direction, the second ridge groups are staggered with the first ridge groups and the third ridge groups, and the staggered engagement of each group of first ridge groups, each group of second ridge groups, and each group of third ridge groups is utilized to achieve the engagement of the first wedge block 102 and the second wedge block 103. In this way, the reliability of the first wedge block 102 and the second wedge block 103 can be improved while avoiding the misalignment or movement between the first wedge block 102 and the second wedge block 103.

[0117] The second rib group may include a third rib 1032 and a fourth rib 1033, the third rib 1032 and the fourth rib 1033 are spaced apart along the first direction (y-axis direction), the length direction of the third rib 1032 and the length direction of the fourth rib 1033 are both parallel to the x-axis direction, and the third rib 1032 and the fourth rib 1033 may form a second groove 1034. It can be understood that the second groove 1034 is surrounded by the inner surface of the third rib 1032, the inner surface of the fourth rib 1033 and the third surface 1031. The inner surface of the third rib 1032 refers to the surface of the third rib 1032 facing the fourth rib 1033, and the inner surface of the fourth rib 1033 refers to the surface of the fourth rib 1033 facing the third rib 1032.

[0118] In some embodiments, the second groove 1034 includes a first inner surface 10341 and a second inner surface 10342 opposite to each other. The first inner surface 10341 can be regarded as the inner surface of the third ridge 1032 , and the second inner surface 10342 can be regarded as the inner surface of the fourth ridge 1033 .

[0119] Fig.12 : is a side view of the second wedge block provided in the embodiment of the present application. Fig.12 (a) shows a side view of the second wedge block, Fig.12 (b) shows Fig.12 The local enlarged structure of the D1 region in (a). Fig.12 (c) shows Fig.12 A locally enlarged structure of the D2 region in (a).

[0120] like Fig.12 As shown in (a), the first inner surface 10341 and the second inner surface 10342 of the second groove 1034 are both inclined relative to the third surface 1031, and form an angle α4 toward the third surface 1031, and the angle α4 is an acute angle, a right angle or an obtuse angle, and the angle α4 is also toward the first surface 101. The angle α4 is determined according to the degree of inclination of the first inner surface 10341 and the second inner surface 10342. The inclination of the first inner surface 10341 is the same as the inclination of the outer surface 1022a of the first convex ridge 1022, so that the first inner surface 10341 and the outer surface 1022a of the first convex ridge 1022 can achieve surface-to-surface matching; the inclination of the second inner surface 10342 is the same as the inclination of the outer surface 1023a of the second convex ridge 1023, so that the second inner surface 10342 and the outer surface 1023a of the second convex ridge 1023 can achieve surface-to-surface matching.

[0121] The shape of the second groove 1034 is the same as the shape of the first area surrounded by the first ridge 1022 and the second ridge 1023, so as to achieve the surface-to-surface matching of the second groove 1034 with the first ridge 1022 and the second ridge 1023. The groove bottom width of the second groove 1034 is W3, and the slot width of the second groove 1034 is W4. The groove bottom width W3 is the distance between the bottom end of the first inner surface 10341 and the bottom end of the second inner surface 10342, and the slot width W4 is the distance between the upper end of the first inner surface 10341 and the upper end of the second inner surface 10342. Fig.10 The bottom width W3 of the second groove 1034 is equal to the upper width W1 of the first region, and the notch width W4 of the second groove 1034 is equal to the lower width W2 of the first region. In this way, the second groove 1034 can cover the first convex ridge 1022 and the second convex ridge 1023 to achieve the interlocking of the first wedge block 102 and the second wedge block 103.

[0122] like Fig.12 As shown in (b) and (c), the first inner surface 10341 includes a first protrusion 1035, and the second inner surface 10342 includes a second protrusion 1036, and the first protrusion 1035 is opposite to the second protrusion 1036. Fig.11 As shown in (b), the first protrusion 1035 protrudes from the first inner surface 10341 toward the second inner surface 10342 , and similarly, the second protrusion 1036 protrudes from the second inner surface 10342 toward the first inner surface 10341 .

[0123] The first protrusion 1035 has the same inclination as the first inner surface 10341, and the second protrusion 1036 has the same inclination as the second inner surface 10342. The outer edge of the first protrusion 1035 and the outer edge of the second protrusion 1036 may enclose a fourth region (not shown in the figure), and the cross-sectional shape of the fourth region is a trapezoid, and may further be an isosceles trapezoid.

[0124] The shape of the fourth region is the same as the shape of the second region enclosed by the first stopper 301 and the second stopper 302. The upper width of the fourth region (not shown in the figure) is smaller than the groove bottom width W3 of the third region and is equal to the upper width of the second region; the lower width of the fourth region (not shown in the figure) is smaller than the notch width W4 of the third region and is equal to the lower width of the second region; the upper width of the fourth region is smaller than the lower width of the fourth region. The upper width of the fourth region refers to the distance between the bottom end of the first protrusion 1035 and the bottom end of the second protrusion 1036, and the lower width of the fourth region refers to the distance between the upper end of the first protrusion 1035 and the upper end of the second protrusion 1036.

[0125] In this way, when the second wedge block 103 is buckled on the first wedge block 102, the first protrusion 1035 abuts against the first limit block 301, and the second protrusion 1036 abuts against the second limit block 302. By making the first protrusion 1035 contact the inclined surface of the first limit block 301, and the second protrusion 1036 contact the inclined surface of the second limit block 302, the relative height of the second wedge block 103 and the first wedge block 102 is adjusted, thereby facilitating the adjustment of the height of the slide slot 104.

[0126] Fig.13 It is a schematic diagram of the matching structure of the first wedge block and the second wedge block provided in an embodiment of the present application.

[0127] like Fig.13 As shown, in some embodiments, the second groove 1034 is opposite to the first groove 1024 on the first wedge block 102; the third ridge 1032 is opposite to the first slot 1026, and the fourth ridge 1033 is opposite to the second slot 1027; the ridge 1025 on the left is opposite to the third surface 1031 adjacent to the third ridge 1032, and the ridge 1025 on the right is opposite to the third surface 1031 adjacent to the fourth ridge 1033.

[0128] The second groove 1034 is configured to accommodate the first ridge group when the second wedge block 103 is buckled on the first wedge block 102. The second groove 1034 is connected to the first groove 1024, and the second groove 1034 accommodates the first ridge 1022 and the second ridge 1023. The elastic member 200 is located in the space surrounded by the second groove 1034 and the first groove 1024.

[0129] When the second wedge block 103 is buckled onto the first wedge block 102, the first protrusion 1035 is configured to abut against the first outer surface 3011 of the first limit block 301 and apply a force to the first limit block 301, and the second protrusion 1036 is configured to abut against the second outer surface 3021 of the second limit block 302 and apply a force to the second limit block 302. The first limit block 301 and the second limit block 302 are configured to move toward each other under the force, so that the elastic member 200 is deformed to adjust the distance between the third surface 1031 of the second wedge block 103 and the first surface 101, thereby adjusting the height of the slide groove 104.

[0130] For example, along the z-axis direction, if the second wedge block 103 moves toward the first wedge block 102, for example, the second wedge block 103 moves downward, the third ridge 1032 of the second wedge block 103 is embedded in the first slot 1026, the fourth ridge 1033 of the second wedge block 103 is embedded in the second slot 1027, and the first ridge 1022 and the second ridge 1023 are embedded in the second groove 1034. The first protrusion 1035 of the second wedge block 103 abuts against the first outer surface 3011 of the first limiting block 301, and the second protrusion 1036 abuts against the second outer surface 3021 of the second limiting block 302. As the second wedge block 103 further moves toward the first wedge block 102, the first protrusion 1035 applies a rightward force to the first limiting block 301, and the second protrusion 1036 applies a leftward force to the second limiting block 302.

[0131] The first limit block 301 and the second limit block 302 are moved toward each other by the force, and the first limit block 301 and the second limit block 302 squeeze the elastic member 200 between them, so that the elastic member 200 is deformed. The deformation of the elastic member 200 can reduce the distance between the first limit block 301 and the second limit block 302, and then the second wedge block 103 can move further toward the first wedge block 102, and so on. In this way, the relative height of the second wedge block 103 and the first wedge block 102 can be reduced, and the fitting depth of the second wedge block 103 and the first wedge block 102 can be increased, thereby reducing the distance between the third surface 1031 of the second wedge block 103 and the first surface 101, so as to reduce the height H of the slide groove 104. 104 .

[0132] When the second wedge block 103 is fully engaged with the first wedge block 102, the first outer surface 3011 of the first stop block 301 is coplanar with the outer surface 1022a of the first ridge 1022, and the second outer surface 3021 of the second stop block 302 is coplanar with the outer surface 1023a of the second ridge 1023. The first inner surface 10341 of the second groove 1034 abuts against the outer surface 1022a of the first ridge 1022 to achieve a surface-to-surface fit, and the second inner surface 10342 abuts against the outer surface 1023a of the second ridge 1023 to achieve a surface-to-surface fit. The upper ends of the first ridge 1022 and the second ridge 1023 of the first wedge block 102, and the upper end of the elastic member 200 abut against the groove bottom surface of the second groove 1034 of the second wedge block 103. The end of the third ridge 1032 of the second wedge block 103 abuts against the bottom surface of the first slot 1026 , and the end of the fourth ridge 1033 abuts against the bottom surface of the second slot 1027 . The end of the ridge 1025 abuts against the third surface 1031 of the second wedge block 103 .

[0133] If it is necessary to increase the height H of the chute 104 104 , the second wedge block 103 can be moved along the z-axis in a direction away from the first wedge block 102, for example, the second wedge block 103 moves upward, the force on the first limit block 301 and the second limit block 302 is reduced or disappears, and the extrusion force applied by the first limit block 301 and the second limit block 302 to the elastic member 200 is reduced or disappears, so that the elastic member 200 gradually returns to its initial shape, pushing the first limit block 301 and the second limit block 302 to move in opposite directions, and so on. In this way, the relative height of the second wedge block 103 and the first wedge block 102 can be increased, the fitting depth of the second wedge block 103 and the first wedge block 102 can be reduced, and then the distance between the third surface 1031 of the second wedge block 103 and the first surface 101 can be increased to increase the height H of the slide groove 104. 104 .

[0134] In the embodiment of the present application, the height H of the slide groove 104 can be adjusted by the relative movement of the first wedge block 102 and the second wedge block 103. 104 is a preset height. The preset height is the height corresponding to when the slide groove 104 and the slider 531 can be zero-matched. In this way, when the slider 531 slides in the slide groove 104, the gap between the outer surface of the slider 531 and the inner surface of the slide groove 104 can be reduced, and the slider 531 and the slide groove 104 can avoid the occurrence of a virtual angle under the premise of avoiding jamming during folding or unfolding, thereby improving the rotation accuracy of the shaft mechanism and improving the user's opening and closing experience.

[0135] In some embodiments, when the height H of the chute 104 is 104After adjusting to the preset height, the relative positions of the first wedge block 102 and the second wedge block 103 can be fixed. Exemplarily, the first wedge block 102 and the second wedge block 103 can be fixed by glue.

[0136] In this way, it is possible to avoid displacement of the first wedge block 102 and the second wedge block 103 during use to change the height H of the slide groove 104. 104 , thereby avoiding the reappearance of the virtual angle and affecting the user's opening and closing experience.

[0137] See again Figure 5 and Figure 7 In some embodiments, the slide groove structure may further include: at least one locking structure 400; at least one locking structure 400 passes through the first wedge block 102 and the second wedge block 103. Exemplarily, the locking structure 400 may be a screw, and the number of the locking structures 400 may be two, and the two locking structures 400 are located on opposite sides of the elastic member 200 along the x-axis direction.

[0138] The locking structure 400 is configured to lock the first wedge block 102 and the second wedge block 103 after adjusting the slide groove 104 to a preset height. In this way, the locking structure 400 can be used to fix the relative positions of the first wedge block 102 and the second wedge block 103, so that during use, the height H of the slide groove 104 is 104 Always the preset height.

[0139] In some embodiments, the locking structure 400 is further configured to provide a force to the second wedge block 103 so that the second wedge block 103 moves along the z-axis direction.

[0140] For example, when the height H of the chute 104 is lowered 104 In the scenario, the locking structure 400 provides a downward force along the z-axis direction to the second wedge block 103 through the tightening operation, so as to drive the second wedge block 103 to move toward the first wedge block 102.

[0141] When increasing the height H of the chute 104 104 In the scenario of, the locking structure 400 gradually eliminates the force on the second wedge block 103 by loosening, thereby reducing or eliminating the force on the first limit block 301 and the second limit block 302, so that the elastic member 200 gradually recovers to its initial shape. The shape recovery of the elastic member 200 exerts opposite forces on the first limit block 301 and the second limit block 302, and moves in opposite directions, thereby driving the second wedge block 103 to move in a direction away from the first wedge block 102.

[0142] In some embodiments, the locking structure 400 is used to drive the relative movement of the second wedge block 103 and the first wedge block 102 to adjust the height H of the slide groove 104. 104 After adjusting to the preset height, a virtual angle test is performed based on the slide groove structure with the preset height slide groove 104. After the virtual angle test is passed, the locking structure 400 can be fixed to the first wedge block 102 and the second wedge block 103 by welding or gluing to prevent the locking structure 400 from automatically loosening during subsequent use, causing the first wedge block 102 and the second wedge block 103 to move, thereby changing the height H of the slide groove 104. 104 .

[0143] The slide groove structure provided in the embodiment of the present application utilizes the locking structure 400 to realize the connection between the first wedge block 102 and the second wedge block 103, and the height of the slide groove 104 is precisely adjusted by adjusting the tightening or loosening state of the locking structure 400 and the deformation of the elastic member 200. In this way, the slide groove 104 and the slider 531 can be zero-matched, avoiding the gap between the slide groove 104 and the slider 531 to be too large, thereby avoiding the appearance of a virtual angle. In the shaft mechanism, the slide groove structure can achieve zero matching between the slider and the slide groove while avoiding jamming during folding or unfolding, thereby improving the rotation accuracy of the shaft mechanism and improving the user's opening and closing experience.
