Hinge module and smart glasses

Abstract

This invention discloses a hinge module and smart glasses. The hinge module includes a first support, a second support, a first rotating wheel, a second rotating wheel, an elastic element, a second movable element, and a second movable element. The hinge module has an open state and an outward-folding state. The direction of the first movable element toward the second movable element is a first direction. During the outward folding of the temples, the larger the outward folding angle, the greater the movement distance of the first movable element along the first direction under the driving action of the first rotating wheel, and the greater the movement distance of the second movable element along the first direction under the driving action of the second rotating wheel. This ensures that the compression of the elastic element tends to be constant during the outward folding of the temples, thereby making the tendency of the hinge module to return to the open state tend to be constant. The technical solution of this invention aims to reduce the changing trend of the clamping force of the temples on the user's head during the outward folding of the temples relative to the frame.

Description

Technical Field

[0001] This invention relates to the field of head-mounted display technology, and in particular to a hinge module and smart glasses. Background Technology

[0002] With the development of head-mounted display devices (such as smart glasses), users' demands for wearing comfort are becoming increasingly apparent. In existing technologies, to allow users with larger head shapes to wear them, smart glasses are usually deformed so that the temples fold outward relative to the frame. This creates a larger space between the temples for users with larger head shapes. However, the larger the head shape, the greater the degree to which the temples fold outward relative to the frame, resulting in a greater clamping force between the temples and the head, thus reducing the wearing comfort of the smart glasses. Summary of the Invention

[0003] The main objective of this invention is to provide a hinge module that reduces the changing trend of the clamping force on the user's head during the outward flipping of the temples relative to the frame.

[0004] To achieve the above objectives, the hinge module proposed in this invention is applied to smart glasses, the hinge module comprising:

[0005] The first bracket and the second bracket are used to connect the frame and the temple. The second bracket is rotatably connected to the first bracket so that the hinge module has an open state in which the temple is opened relative to the frame and an outward state in which the temple is turned outward relative to the frame.

[0006] Both the first and second rotating wheels rotate following the second support.

[0007] An elastic element is disposed between the first rotating wheel and the second rotating wheel; and

[0008] A first movable member and a second movable member are provided. The first movable member is located between the first rotating wheel and the elastic member, and the second movable member is located between the second rotating wheel and the elastic member. The direction from the first movable member toward the second movable member is the first direction.

[0009] During the process of the temple flipping outward, the greater the flipping angle, the greater the movement distance of the first movable member along the first direction under the driving action of the first rotating wheel, and the greater the movement distance of the second movable member along the first direction under the driving action of the second rotating wheel. As a result, during the process of the temple flipping outward, the compression of the elastic member tends to be constant, thereby making the tendency of the hinge module to return to the open state tend to be constant.

[0010] Optionally, the first rotating wheel has a first protrusion on the side near the first movable member, the first movable member has a first pushing surface for the first protrusion to slide, the first pushing surface has a first guide surface, and during the process of resetting from the outward-folded state to the open state, the rotation direction of the second bracket relative to the first bracket is a second direction. In the second direction, the first guide surface is inclined towards the first direction. The second rotating wheel has a second protrusion on the side near the second movable member, the second movable member has a second pushing surface for the second protrusion to slide, the second pushing surface has a fifth guide surface, and in the second direction, the fifth guide surface is inclined towards the first direction.

[0011] During the outward rotation of the temple, the first protrusion slides on the first guide surface to make the first movable member move in the first direction, and the second protrusion slides on the fifth guide surface to make the second movable member move in the first direction.

[0012] Optionally, in the second direction, the first abutting surface is provided with a second guide surface located downstream of the first guide surface. The first guide surface and the second guide surface intersect and restrict a first concave valley. In the depth direction of the first concave valley, the distance between the first guide surface and the second guide surface gradually decreases. When the first protrusion abuts against the first guide surface and the second guide surface, the hinge module is in the open state and has a tendency to maintain the open state.

[0013] Optionally, in the second direction, the first abutting surface is provided with a first damping surface located downstream of the second guide surface. The first damping surface intersects with the second guide surface. When the first protrusion abuts against the first damping surface, the first protrusion tends to remain on the first damping surface.

[0014] Optionally, the hinge module has a folded state that allows the temple to fold relative to the frame. In the second direction, the first abutting surface is further provided with a third guide surface downstream of the first damping surface and a fourth guide surface downstream of the third guide surface. The third guide surface and the fourth guide surface intersect and restrict a second concave valley. In the depth direction of the second concave valley, the distance between the third guide surface and the fourth guide surface gradually decreases. When the first protrusion abuts against the third guide surface and the fourth guide surface, the hinge module is in the folded state and has a tendency to maintain the folded state.

[0015] Optionally, the second abutting surface is provided with a second damping surface that intersects with the fifth guide surface. The second damping surface is located downstream of the fifth guide surface in the second direction. When the second protrusion abuts against the second damping surface, the second protrusion tends to stay on the second damping surface.

[0016] Optionally, there are multiple first protrusions and multiple first abutting surfaces, with one first protrusion corresponding to one first abutting surface; there are multiple second protrusions and multiple second abutting surfaces, with one second protrusion corresponding to one second abutting surface.

[0017] Optionally, the first bracket includes a first mounting plate with a first through hole, the second bracket includes a second mounting plate opposite to the first mounting plate with a first fixing hole, the first wheel includes a first rotating shaft rotatably disposed in the first through hole, and a first fixing shaft and a first limiting plate respectively disposed at both ends of the first rotating shaft, the first rotating shaft extends along the first direction, the first fixing shaft is connected to the first fixing hole, the first limiting plate is limited and engaged with the side of the first mounting plate away from the second mounting plate, and the side of the first limiting plate away from the first rotating shaft is provided with the first protrusion.

[0018] Optionally, the first bracket includes a third mounting plate with a second through hole, the second bracket includes a fourth mounting plate opposite to the third mounting plate with a second fixing hole, the second wheel includes a second rotating shaft rotatably disposed in the second through hole, and a second fixing shaft and a second limiting plate respectively disposed at both ends of the second rotating shaft, the second rotating shaft extending along the first direction, the second fixing shaft connected to the second fixing hole, the second limiting plate being limited and engaged with the side of the third mounting plate away from the fourth mounting plate, and the side of the second limiting plate away from the second rotating shaft having a second protrusion.

[0019] Optionally, the first movable member has a first guide shaft extending along the first direction on the side near the first rotating wheel, and the first guide shaft is movably inserted through the first rotating wheel.

[0020] Optionally, the first movable member has a second guide shaft extending along the first direction on the side away from the first rotating wheel, and the second guide shaft is movably inserted through the elastic member.

[0021] Optionally, the second movable member has a third guide shaft extending along the first direction on the side near the second rotating wheel, and the third guide shaft is movably inserted through the second rotating wheel.

[0022] Optionally, the second movable member has a fourth guide shaft extending along the first direction on the side away from the second rotating wheel, and the fourth guide shaft is movably inserted through the elastic member.

[0023] Optionally, the first bracket has a receiving cavity with an opening on one side, and the first rotating wheel, the second rotating wheel, the elastic element, the first movable element, and the second movable element are housed in the receiving cavity. The hinge module also includes a cover plate that covers the opening of the receiving cavity.

[0024] The present invention also proposes a smart glasses, the smart glasses comprising:

[0025] Picture frames;

[0026] temples; and

[0027] In the aforementioned hinge module, one of the first bracket and the second bracket of the hinge module is connected to the frame, and the other is connected to the temple.

[0028] In the technical solution of this invention, the hinge module includes a first bracket and a second bracket. One of the first bracket and the second bracket is used to connect to the frame, and the other is used to connect to the temples. The second bracket is rotatably connected to the first bracket. Thus, the frame and temples of the smart glasses can rotate relative to each other through the first bracket and the second bracket. It should be noted that the first bracket and the second bracket can have a direct rotatable connection, or they can achieve indirect rotation through other components. The hinge module has an open state where the temples are open relative to the frame, and an outward-folded state where the temples are folded outward relative to the frame. It can be understood that when the hinge module is in the open state and the outward-folded state, the smart glasses are in a wearing state for the user to wear. When the user wears the glasses, for a suitable head shape, the hinge module enters the open state; for a larger head shape, the hinge module enters the outward-folded state. The hinge module also includes a first rotating wheel, a second rotating wheel, an elastic element, a first movable element, and a second movable element. Both the first and second rotating wheels rotate with the second bracket. An elastic element is positioned between the first and second rotating wheels. A first movable element is positioned between the first rotating wheel and the elastic element, and a second movable element is positioned between the second rotating wheel and the elastic element. The direction from the first movable element towards the second movable element is defined as the first direction. During the outward rotation of the temples, the greater the outward angle, the greater the distance the first movable element moves along the first direction under the drive of the first rotating wheel, and the greater the distance the second movable element moves along the first direction under the drive of the second rotating wheel. This ensures that the compression of the elastic element tends to be constant during the outward rotation of the temples, thus making the tendency of the hinge module to return to the open state tend to be constant. In this way, the first and second movable elements jointly control the compression of the elastic element. The first movable element compresses the elastic element, and the second movable element extends it to reduce the compression. This weakens the tendency of the hinge module to return to the open state while ensuring that the clamping force on the user is greater than zero, allowing the user to wear the smart glasses relatively stably. This ensures that the clamping force experienced by users with larger head shapes when wearing smart glasses is not significantly different from that experienced by users with suitable head shapes, thus improving the wearing comfort of smart glasses.

[0047] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0050] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean abutting; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0052] With the development of head-mounted display devices (such as smart glasses), users' demands for wearing comfort are becoming increasingly apparent. In existing technologies, to accommodate users with larger head sizes, smart glasses are typically deformed so that the temples fold outwards relative to the frame. This creates a larger space between the temples for users with larger heads. However, the larger the head, the greater the degree of outward folding of the temples relative to the frame, resulting in a greater clamping force on the head and reduced wearing comfort. Therefore, this invention proposes a hinge module designed to reduce the changing trend of the clamping force on the user's head during the outward folding of the temples relative to the frame.

[0053] Reference Figure 1-14In one embodiment of the present invention, the hinge module 200 is applied to a device that requires a rotatable connection between two components. This paper uses a smart glasses 100 in a head-mounted display device as an example to describe the hinge module 200. The hinge module 200 includes a first bracket 210 and a second bracket 220. One of the first bracket 210 and the second bracket 220 is used to connect the frame 110, and the other is used to connect the temple 140. The second bracket 220 is rotatably connected to the first bracket 210. Thus, the frame 110 and the temple 140 of the smart glasses 100 can rotate relative to each other through the first bracket 210 and the second bracket 220. It should be noted that the first bracket 210 and the second bracket 220 can have a direct rotatable connection, or they can achieve indirect rotation through other components. The hinge module 200 has an open state where the temple 140 is open relative to the frame 110, and an outward-folded state where the temple 140 is folded outward relative to the frame 110. It is understood that when the hinge module 200 is in the open state and the outward-folding state, the smart glasses 100 are in the wearing state for the user to wear. When the user wears them, for a suitable head shape, the hinge module 200 enters the open state; for a larger head shape, the hinge module 200 enters the outward-folding state. The hinge module 200 also includes a first rotating wheel 330, a second rotating wheel 400, an elastic element 310, a first movable element 340, and a second movable element 360. The first rotating wheel 330 and the second rotating wheel 400 both rotate with the second bracket 220. The elastic element 310 is located between the first rotating wheel 330 and the second rotating wheel 400. The first movable element 340 is located between the first rotating wheel 330 and the elastic element 310. The second movable element 360 is located between the second rotating wheel 400 and the elastic element 310. The direction from the first movable element 340 towards the second movable element 360 is the first direction. During the outward rotation of the temple 140, the greater the rotation angle, the greater the movement distance of the first movable member 340 along the first direction under the drive of the first rotating wheel 330, and the greater the movement distance of the second movable member 360 along the first direction under the drive of the second rotating wheel 400. This ensures that the compression of the elastic member 310 tends to be constant during the outward rotation of the temple 140, thus making the tendency of the hinge module 200 to return to the open state tend to be constant. In this way, the first movable member 340 and the second movable member 360 jointly control the compression of the elastic member 310. The first movable member 340 compresses the elastic member 310, and the second movable member 360 extends the elastic member 310 to reduce the compression. This weakens the tendency of the hinge module 200 to return to the open state while ensuring that the clamping force on the user is greater than zero, allowing the user to wear the smart glasses 100 more stably. This ensures that the clamping force experienced by users with larger head shapes when wearing the smart glasses 100 is not significantly different from that experienced by users with suitable head shapes, thus improving the wearing comfort of the smart glasses 100.

[0054] It is worth mentioning that the number of the first rotating wheel 330, the second rotating wheel 400, the elastic element 310, the first movable element 340, and the second movable element 360 can be set according to actual needs.

[0055] Optionally, in one embodiment, the first rotating wheel 330 is provided with a first protrusion 334 on one side near the first movable member 340, the first movable member 340 is provided with a first pushing surface 350 for the first protrusion 334 to slide, the first pushing surface 350 is provided with a first guide surface 352, during the process of resetting from the outward-folded state to the open state, the rotation direction of the second bracket 220 relative to the first bracket 210 is a second direction, in the second direction, the first guide surface 352 is inclined towards the first direction, the second rotating wheel 400 is provided with a second protrusion 410 on one side near the second movable member 360, the second movable member 360 is provided with a second pushing surface 370 for the second protrusion 410 to slide, the second pushing surface 370 is provided with a fifth guide surface 371, in the second direction, the fifth guide surface 371 is inclined towards the first direction. During the outward folding of the temple 140, the first protrusion 334 slides on the first guide surface 352, causing the first movable member 340 to move in the first direction, and the second protrusion 410 slides on the fifth guide surface 371, causing the second movable member 360 to move in the first direction. Thus, the first movable member 340 and the second movable member 360 jointly control the compression of the elastic member 310. The first movable member 340 compresses the elastic member 310, and the second movable member 360 extends the elastic member 310, thereby reducing the compression. This weakens the tendency of the hinge module 200 to return to the open state and ensures that the clamping force on the user is greater than zero, allowing the user to wear the smart glasses 100 more stably. Therefore, the clamping force experienced by users with larger head shapes when wearing the smart glasses 100 is not significantly different from that experienced by users with suitable head shapes, improving the wearing comfort of the smart glasses 100.

[0056] Specifically, when a user with a large head wears the smart glasses 100, the user flips the temples 140 outward relative to the frame 110, causing the first support 210 and the second support 220 to rotate relative to each other. This causes the first rotating wheel 330 to rotate relative to the first movable member 340, and the second rotating wheel 400 to rotate relative to the second movable member 360. Thus, during the process of resetting from the open state to the flipped-out state, the first protrusion 334 slides on the first guide surface 352 to cause the first movable member 340 to move along the first direction, thereby allowing the elastic member 310 to... When compressed, the elastic element 310 has elastic potential energy. The second protrusion 410 slides on the fifth guide surface 371 to make the second movable element 360 move in the first direction, thereby allowing the elastic element 310 to stretch, that is, reducing the degree of compression of the elastic element 310. It should be noted that at this time, the elastic element 310 is in a compressed state. Under the action of the elastic element 310, the hinge module 200 has a tendency to return from the outward flip state to the open state, thereby making the temple 140 generate a clamping force on the user. When the user removes the smart glasses 100, the elastic element 310 releases its elastic potential energy and extends to push the first movable element 340. With the cooperation of the first guide surface 352 and the first protrusion 334, the first rotating wheel 330 drives the temple 140 to rotate, so that the hinge module 200 changes from the outward-folded state to the open state, so that the hinge module 200 can enter the open state. At the same time, the second movable element 360 moves closer to the first rotating wheel 330 along the extension and retraction direction of the elastic element 310, in preparation for the hinge module 200 to enter the outward-folded state again.

[0057] However, this design is not limited to this. In other embodiments, the cooperation structure of the first rotating wheel 330 and the first movable member 340 can also be other structural forms, and the cooperation structure of the second rotating wheel 400 and the second movable member 360 can also be other structural forms. As long as the larger the outward angle during the outward flipping of the temple 140, the greater the movement distance of the first movable member 340 under the driving action of the first rotating wheel 330, and the greater the movement distance of the second movable member 360 under the driving action of the second rotating wheel 400, so that the compression amount of the elastic member 310 tends to be constant during the outward flipping of the temple 140, thereby making the tendency of the hinge module 200 to return to the open state tend to be constant.

[0058] Optionally, in one embodiment, the first rotating wheel 330 and the second bracket 220 are separate components, and the first rotating wheel 330 and the second bracket 220 can be connected together by assembly. Thus, when the first rotating wheel 330 is damaged, only the first rotating wheel 330 needs to be replaced, which helps reduce the degree of maintenance required for the hinge module 200. However, this design is not limited to this. In other embodiments, the first rotating wheel 330 and the second bracket 220 are integrally formed, which can reduce the assembly steps of the hinge module 200 and improve the assembly efficiency of the hinge module 200.

[0059] Optionally, in one embodiment, the second rotating wheel 400 and the second bracket 220 are separate components, and the second rotating wheel 400 and the second bracket 220 can be connected together by assembly. Thus, when the second rotating wheel 400 is damaged, only the second rotating wheel 400 needs to be replaced, which helps reduce the degree of maintenance required for the hinge module 200. However, this design is not limited to this. In other embodiments, the second rotating wheel 400 and the second bracket 220 are integrally formed, which can reduce the assembly steps of the hinge module 200 and improve the assembly efficiency of the hinge module 200.

[0060] Optionally, in one embodiment, in the second direction, the first abutting surface 350 is provided with a second guide surface 353 located downstream of the first guide surface 352. The first guide surface 352 and the second guide surface 353 intersect and define a first valley 351. In the depth direction of the first valley 351, the distance between the first guide surface 352 and the second guide surface 353 gradually decreases. When the first protrusion 334 abuts against the first guide surface 352 and the second guide surface 353, the hinge module 200 is in an open state and tends to remain in the open state. Thus, the first valley 351 is generally V-shaped groove. Thus, when the first protrusion 334 abuts against the first guide surface 352 and the second guide surface 353, it is beneficial for the hinge module 200 to tend to remain in the open state. Thus, when the hinge module 200 is in the open state, the temple 140 will not easily wobble left and right, which is beneficial to improving the user's experience of wearing the smart glasses 100. It should be noted that either the first guide surface 352 or the second guide surface 353 can be a plane or a curved surface, without limitation. Furthermore, the first guide surface 352 and the second guide surface 353 can be arranged symmetrically or asymmetrically, without limitation.

[0061] Optionally, in one embodiment, in the second direction, the first abutting surface 350 is provided with a first damping surface 354 located downstream of the second guide surface 353. The first damping surface 354 intersects with the second guide surface 353. When the first protrusion 334 abuts against the first damping surface 354, the first protrusion 334 tends to stay on the first damping surface 354. It can be understood that the hinge module 200 has a folded state that folds the temple 140 relative to the frame 110. Thus, during the process of the hinge module 200 resetting from the open state to the folded state, the first damping surface 354 provides a stopping position for the first protrusion 334, so that the first bracket 210 and the second bracket 220 can form multiple relatively stable angles, that is, the temple 140 and the frame 110 can form multiple relatively stable angles. In this way, the user's choices are enriched and the user's sense of control over the smart glasses 100 is improved. The temples 140 and the frame 110 form several relatively stable angles, which helps users to customize the shape of the smart glasses 100. When the user is not wearing the smart glasses 100, it can decorate the surrounding space. Furthermore, the first damping surface 354 provides resistance to the sliding of the first protrusion 334, giving the user a sense of sophistication. It should be noted that the first damping surface 354 can be perpendicular to the first direction, or it can be set at an acute angle to the first direction, as long as the first damping surface 354 provides resistance for the first protrusion 334 to rest on the first damping surface 354.

[0062] To prevent excessive resistance when the first protrusion 334 slides on the first damping surface 354, and to facilitate the user's rotation of the temple 140, optionally, in one embodiment, the first damping surface 354 is located between the highest and lowest points of the first guide surface 352 in the valley depth direction of the first concave valley 351. Of course, in other embodiments, if it is considered that the temple 140 will not easily rotate when driven by a certain external force, then the first damping surface 354 can also be higher than the highest point of the first guide surface 352 in the valley depth direction of the first concave valley 351, so that a larger pressure is generated between the first protrusion 334 and the first damping surface 354, thereby enabling the first damping surface 354 to provide greater resistance to the first protrusion 334.

[0063] Optionally, in one embodiment, the hinge module 200 has a folded state in which the temple 140 is folded relative to the frame 110. In the second direction, the first abutting surface 350 is further provided with a third guide surface 356 downstream of the first damping surface 354 and a fourth guide surface 357 downstream of the third guide surface 356. The third guide surface 356 and the fourth guide surface 357 intersect and limit a second valley 355. In the depth direction of the second valley 355, the distance between the third guide surface 356 and the fourth guide surface 357 gradually decreases. When the first protrusion 334 abuts against the third guide surface 356 and the fourth guide surface 357, the hinge module 200 is in a folded state and tends to remain in the folded state. Thus, the second valley 355 is generally V-shaped groove structure. Thus, when the first protrusion 334 abuts against the third guide surface 356 and the fourth guide surface 357, it is beneficial for the hinge module 200 to tend to remain in the folded state. Thus, when the hinge module 200 is in the folded state, the temple 140 will not easily wobble from side to side, which helps improve the user's experience of wearing the smart glasses 100. It should be noted that either the third guide surface 356 or the fourth guide surface 357 can be a plane or a curved surface, without restriction. In addition, the third guide surface 356 and the fourth guide surface 357 can be arranged symmetrically or asymmetrically, without restriction.

[0064] Optionally, in one embodiment, the second abutting surface 370 is provided with a second damping surface 372 intersecting with the fifth guide surface 371. The second damping surface 372 is located downstream of the fifth guide surface 371 in the second direction. When the second protrusion 410 abuts against the second damping surface 372, the second protrusion 410 tends to stay on the second damping surface 372. It can be understood that the hinge module 200 has a folded state that folds the temple 140 relative to the frame 110. Thus, during the process of the hinge module 200 returning from the open state to the folded state, the second damping surface 372 provides a stopping position for the second protrusion 410, so that the first bracket 210 and the second bracket 220 can form multiple relatively stable angles, that is, the temple 140 and the frame 110 can form multiple relatively stable angles. In this way, the user's choices are enriched and the user's sense of control over the smart glasses 100 is improved. The temples 140 and the frame 110 form several relatively stable angles, which helps users to customize the shape of the smart glasses 100. When the user is not wearing the smart glasses 100, it can decorate the surrounding space. Furthermore, the second damping surface 372 provides resistance to the sliding of the second protrusion 410, giving the user a sense of sophistication. It should be noted that the second damping surface 372 can be perpendicular to the first direction, or it can be set at an acute angle to the first direction, as long as the second damping surface 372 provides resistance for the second protrusion 410 to rest on the first damping surface 354.

[0065] Optionally, in one embodiment, multiple first protrusions 334 and multiple first abutting surfaces 350 are provided, with one first protrusion 334 corresponding to one first abutting surface 350. Multiple second protrusions 410 and multiple second abutting surfaces 370 are provided, with one second protrusion 410 corresponding to one second abutting surface 370. Thus, for a single first protrusion 334 and second protrusion 410, multiple first protrusions 334 help reduce wear, and multiple second protrusions 410 help reduce wear. The number of first protrusions 334 and second protrusions 410 can be set according to actual needs. Correspondingly, the number of first abutting surfaces 350 matches the number of first protrusions 334, and the number of second abutting surfaces 370 matches the number of second protrusions 410. Furthermore, in one embodiment, a plurality of first protrusions 334 are evenly spaced around the rotation axis of the first rotating wheel 330. Thus, when the first rotating wheel 330 rotates relative to the first movable member 340, the plurality of first protrusions 334 can exert a force on the first movable member 340, making the force distribution on the first movable member 340 more uniform, thereby ensuring more stable movement of the first movable member 340. A plurality of second protrusions 410 are evenly spaced around the rotation axis of the second rotating wheel 400. Thus, when the second rotating wheel 400 rotates relative to the second movable member 360, the plurality of second protrusions 410 can exert a force on the second movable member 360, making the force distribution on the second movable member 360 more uniform, thereby ensuring more stable movement of the second movable member 360. Furthermore, in one embodiment, when two first protrusions 334 respectively abut against the corresponding first guide surface 352 and second guide surface 353, the hinge module 200 can be more stably maintained in the open state. When the two first protrusions 334 abut against the corresponding third guide surface 356 and fourth guide surface 357 respectively, the hinge module 200 can be kept in the folded state more stably.

[0066] Optionally, in one embodiment, the first bracket 210 includes a first mounting plate 211 with a first through hole 212, the second bracket 220 includes a second mounting plate 221 opposite to the first mounting plate 211 with a first fixing hole 222, the first rotating wheel 330 includes a first rotating shaft 331 rotatably disposed in the first through hole 212, and a first fixing shaft 332 and a first limiting plate 333 respectively disposed at both ends of the first rotating shaft 331.

[0067] Thus, during assembly, the second mounting plate 221 is overlapped onto the first mounting plate 211, and the first fixing shaft 332 of the first rotating wheel 330 is inserted into the first fixing hole 222 of the second mounting plate 221. The first fixing shaft 332 and the first fixing hole 222 can be fixed by interference fit or spot welding. The first rotating shaft 331 of the first rotating wheel 330 is housed in the first through hole 212 of the first mounting plate 211. The first limiting plate 333 is located on the side of the first mounting plate 211 away from the second mounting plate 221. Since the diameter of the first limiting plate 333 is larger than the diameter of the first through hole 212, it can play a limiting installation role, thereby enabling the first bracket 210 and the second bracket 220 to be rotatably connected by the first rotating wheel 330. Optionally, the first mounting plate 211 has a first boss 213 on the side of the first mounting plate 211 near the second mounting plate 221 corresponding to the periphery of the first through hole 212, and the second mounting plate 221 overlaps the end face of the first boss 213. By providing a first boss 213 for the first mounting plate 211 to overlap, the contact area between the first mounting plate 211 and the second mounting plate 221 can be reduced, frictional resistance can be reduced, and the rotation between the two can be made smoother.

[0068] Optionally, in one embodiment, the first bracket 210 includes a third mounting plate 214 with a second through hole 215. The second bracket 220 includes a fourth mounting plate 223 opposite to the third mounting plate 214 with a second fixing hole 224.

The side of the second limiting plate 470 away from the second rotating shaft 450 has a second protrusion 410.

[0069] Thus, during assembly, the fourth mounting plate 223 is overlapped onto the third mounting plate 214, and the second fixing shaft 460 of the second rotating wheel 400 is inserted into the second fixing hole 224 of the fourth mounting plate 223. The second fixing shaft 460 and the second fixing hole 224 can be fixed by interference fit or spot welding. The second rotating shaft 450 of the second rotating wheel 400 is housed in the second through hole 215 of the third mounting plate 214. The second limiting plate 470 is located on the side of the third mounting plate 214 away from the fourth mounting plate 223. Since the diameter of the second limiting plate 470 is larger than the diameter of the second through hole 215, it can play a limiting installation role, thereby enabling the first bracket 210 and the second bracket 220 to be rotatably connected by the second rotating wheel 400. Optionally, the third mounting plate 214 has a second boss 216 on the side of the third mounting plate 214 near the fourth mounting plate 223 corresponding to the periphery of the first through hole 212, and the fourth mounting plate 223 overlaps the end face of the second boss 216. By providing a second boss 216 for the third mounting plate 214 to overlap, the contact area between the third mounting plate 214 and the fourth mounting plate 223 can be reduced, frictional resistance can be reduced, and the rotation between the two can be made smoother.

[0070] To ensure the connection stability and rotational stability between the first bracket 210 and the second bracket 220, the first bracket 210 further includes a first support plate 218 connecting the first mounting plate 211 and the third mounting plate 214, and the second bracket 220 includes a second support plate 225 connecting the second mounting plate 221 and the fourth mounting plate 223.
