Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge. Background Technique

[0002] A hinge is a mechanical device used to connect two objects and allow relative rotation between them. Traditional hinges generally have an axial connection structure, and most of them can only provide rotational movement and cannot provide translational function. When the two objects connected by the hinge need to continue to translate after rotating to a certain position or state, the traditional hinge cannot provide such a function. Therefore, the applicant began to research and develop hinges with both rotational and translational movements successively in 2023 and submitted patent applications to the State Intellectual Property Office, obtaining application numbers: 2023229078475, 2023232096943, 2024202306330, 2024205374255, 2024211724542, and 2024212962800. In a certain state or several states during the use of the hinges involved in the above patent applications, most of the hinges will be exposed outside the screen window, and the exposed part affects the overall aesthetics. Moreover, in some prior applications, the connection and transmission between gears and racks cause problems such as mechanical noise during the use of the hinges. Content of the Utility Model

[0003] The purpose of the utility model is to provide a hinge to solve the deficiencies of the prior art mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A hinge, the hinge includes a mounting seat, a sliding part, and a synchronous belt group. Among them, the synchronous belt group includes a synchronous belt and two synchronous wheels; the sliding part is slidably connected to the mounting seat, the two synchronous wheels are respectively rotatably arranged at both ends of the sliding part, the synchronous belt is sleeved between the two synchronous wheels, and a point at the bottom of the synchronous belt is fixedly connected to the mounting seat; the synchronous belt group moves reciprocally along the length direction of the mounting seat with the sliding part, and the synchronous belt fixedly connected to the mounting seat drives the synchronous wheel to rotate during the movement.

[0005] Preferably, at least one of the synchronous wheels is a gear, and an internal multi-sided through hole penetrating both sides of the gear is provided at the axis of the gear.

[0006] Preferably, two fixed walls for arranging the sliding part are arranged along the length direction on the upper side of the mounting seat, the two fixed walls are respectively located on both sides of the width direction of the mounting seat, and first grooves are arranged on the opposite surfaces of the two fixed walls.

[0007] Preferably, the sliding part includes a sliding part body and two fixing terminals for setting fixed synchronous pulleys. The two fixing terminals are respectively and fixedly arranged at both ends of the sliding part body. Second grooves are arranged on both sides of the sliding part body. When the sliding part is slidably arranged between two fixing walls of the mounting seat, the second groove on each side is opposite to the corresponding first groove, forming two ball receiving cavities.

[0008] Preferably, the width between the outer side walls of the two side walls of the fixing terminal for setting the synchronous pulley is greater than the width between the inner walls of the two fixing walls, so that the fixing terminal and the fixing wall jointly limit the sliding distance of the sliding part. That is, when the sliding part slides relative to the fixing wall, the fixing terminals at both ends of the sliding part can abut against both ends of the fixing wall to limit the sliding distance of the sliding part.

[0009] Preferably, the sliding part is slidably connected to the mounting seat through a bracket and balls. The bracket is relatively fixed to the side wall of the mounting seat. The balls are arranged in the ball receiving cavities, and the bracket keeps the relative positions of the balls unchanged in the ball receiving cavities.

[0010] Preferably, the bracket is a U-shaped groove, and ball limiting holes are opened on both side walls of the U-shaped groove; when the bracket is arranged between two fixing walls of the mounting seat, the sliding part body is located in the U-shaped groove, and the ball limiting holes keep the balls rotatable and relatively fixed in position in the ball receiving cavities.

[0011] Preferably, fixing wings are arranged on the outer side of the bottom of the U-shaped groove, and wing grooves matching the fixing wings are arranged on the tops of the two fixing walls of the mounting seat. When the U-shaped groove is arranged between the two side walls, the fixing wings are stuck in the wing grooves to keep the position of the U-shaped groove unchanged from that of the mounting seat.

[0012] Preferably, the outer side wall of the U-shaped groove is equal to or slightly smaller than the distance between the inner walls of the two side walls of the mounting seat, the distance between the inner side walls of the U-shaped groove is equal to or slightly larger than the width of the sliding part body, and the height of the sliding part body is equal to or slightly smaller than the depth of the U-shaped groove.

[0013] In addition, as an application of the hinge involved in the foregoing solution, the present invention further provides a drifting screen window. The drifting screen window is arranged on a preset window through the hinge in any one of the foregoing solutions, and the number of hinges is two. The main body of the drifting screen window is connected to the gears in the two hinges through a synchronous shaft; the drifting screen window can reciprocally slide along a direction perpendicular to the synchronous shaft along with the sliding part of the hinge. During the moving process, the gears in the two hinges rotate synchronously, so that the drifting screen window stably forms a pocket position or closes the pocket position on one side of the window; at the same time, the drifting screen window can also rotate around the synchronous shaft to close or open the window through the drifting screen window.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the sliding part and the mounting seat are kept slidably connected through balls, the first groove, the second groove and the bracket. Such a connection method makes the noise smaller during the relative sliding process of the two, and can also ensure the stable connection of the two;

[0016] 2. The width of the fixed terminals at both ends of the sliding part is greater than the distance between the two inner side walls of the fixed wall, which can ensure that the sliding part will not be separated from the fixed part during the reciprocating sliding process, and also limits the maximum distance that can be reached at both ends;

[0017] 3. The synchronous pulleys are arranged at both ends of the sliding part, the synchronous belt is sleeved on the two synchronous pulleys, and one side of the synchronous pulley close to the mounting seat is fixedly connected to the mounting seat. In this way, during the sliding process of the sliding part, the fixed connection part between the synchronous belt and the mounting seat is relatively fixed, so that the synchronous belt can drive the synchronous pulley to rotate;

[0018] 4. In the drift screen window of the present utility model, the synchronous pulleys at both ends of the screen window are connected by a synchronous shaft, so that the synchronous pulleys in the two hinges rotate synchronously, which also ensures that the sliding distances of the sliding parts in the two hinges are equal, so that the screen window can move parallel to the window frame.

[0029] Next, in combination with the Figures 1 - 10 in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] The hinge involved in the present utility model mainly provides a connection method for rotation and translation operations.

[0031] Embodiment 1

[0032] Please refer to Figures 1 - 8 , a hinge provided in this embodiment, the hinge includes a mounting base 10, a sliding part 20 and a synchronous belt group 30. A fixing hole 101 is opened on the mounting base 10. During use, the mounting base 10 can be fixed at a preset position through fastening devices such as screws or rivets. The synchronous belt group 30 includes a synchronous belt 301 and two synchronous pulleys 302; the sliding part 20 is slidably connected to the mounting base 10, and the two synchronous pulleys 302 are respectively rotatably arranged at both ends of the sliding part 20. The synchronous belt 301 is sleeved on the two synchronous pulleys 302. The synchronous belt group 30 can reciprocate along the length direction of the mounting base 10 along with the sliding part 20, and a point at the bottom of the synchronous belt 301 is fixedly connected to the mounting base 10; during the process that the synchronous belt group 30 reciprocates along the length direction of the mounting base 10 along with the sliding part 20, the synchronous belt 301 fixedly connected to the mounting base 10 drives the synchronous pulley 302 to rotate.

[0033] Specifically, since the synchronous belt 301 is fixedly connected to the middle of the mounting base 10, when the synchronous belt group 30 reciprocates along the length direction of the mounting base 10 along with the sliding part 20, the fixed point of the synchronous belt 301 does not move relative to the mounting base 10, and the fixed point of the synchronous belt 301 and the mounting base 10 is movable relative to the sliding part 20, and the synchronous belt 301 is rotatably sleeved on the synchronous pulleys 302 at both ends of the sliding part 20.

[0034] In some embodiments, at least one of the synchronous pulleys 302 is a gear. The synchronous belt 301 is provided with grooves or protrusions matching the teeth on the gear, and a multi-sided through hole penetrating both sides of the gear is provided at the axis center of the gear.

[0035] In some embodiments, two fixing walls 101 for arranging the sliding part 20 are arranged along the length direction on the upper side of the mounting base 10. The fixing walls 101 are integrally and fixedly connected to the mounting base 10. The two fixing walls 101 are respectively located on both sides of the mounting base 10 in the width direction. The space between the two fixing walls 101 is the sliding space for the sliding part 20, and first grooves 1011 are arranged on the opposite surfaces of the two fixing walls 101.

[0036] In some embodiments, the sliding part 20 includes a sliding part main body 201 and two fixing terminals 202 for arranging the fixed synchronous pulley 302. The two fixing terminals 202 are respectively and fixedly arranged at both ends of the sliding part main body 201. Specifically, the fixing terminal 202 has two side walls, and mounting holes for arranging the synchronous pulley 302 are arranged on each side wall. The synchronous pulley 302 is rotatably arranged in the mounting hole through a shaft or fixing ears on both sides of the synchronous pulley; second grooves 2011 are arranged on both sides of the sliding part main body 201. When the sliding part 20 is slidably arranged between the two fixing walls 101 of the mounting base 10, the second groove 2011 on each side is opposite to the corresponding first groove 1011, forming two ball receiving cavities. It should be noted that the distance between the bottom of the first groove and the bottom of the second groove is equal to the diameter of the ball. Of course, in actual production, due to processing precision limitations, the distance between the bottom of the first groove and the bottom of the second groove will be slightly larger than the diameter of the ball.

[0037] The sliding part 20 is slidably connected to the mounting base 10 through a bracket 40 and balls 50. The bracket 40 is relatively fixed to the side wall of the mounting base 10. The balls 50 are arranged in the ball receiving cavities, and the bracket 40 keeps the relative positions of the balls 50 unchanged in the ball receiving cavities (the balls can rotate in the ball receiving cavities).

[0038] It should be noted that the bracket 40 is a U-shaped groove, and ball limiting holes 401 are opened on both side walls of the U-shaped groove; when the bracket 40 is arranged between the two fixing walls 101 of the mounting base 10, the sliding part main body 201 is located in the U-shaped groove, and the balls 50 pass through the ball limiting holes 401. The ball limiting holes 401 keep the balls 50 rotatable and relatively fixed in the ball receiving cavities.

[0039] To ensure that the bracket can be relatively fixed to the two fixing walls of the mounting base, fixing wings 402 are arranged on the outside of the bottom of the U-shaped groove, and wing grooves 1012 matching the fixing wings are arranged on the tops of the two fixing walls 101 of the mounting base 10. When the U-shaped groove is arranged between the two fixing walls 101, the fixing wings 402 are stuck in the wing grooves 1012 so that the U-shaped groove and the mounting base keep their positions unchanged.

[0040] To ensure that the sliding part main body 201 can slide within the U-shaped groove, and the sliding distance of the sliding part 20 is limited jointly by the fixed terminal 202 at the end and the fixed wall 101, the outer side wall of the U-shaped groove is equal to or slightly smaller than the distance between the inner walls of the two fixed walls 101 of the mounting base 10. The distance between the inner side walls of the U-shaped groove is equal to or slightly larger than the width of the sliding part main body 201. The height of the sliding part main body 201 is equal to or slightly smaller than the depth of the U-shaped groove, so that the sliding part main body 201 is located between the synchronous belts 301. Among them, the fixed terminal 202 is used to set the width between the outer side walls of the two side walls of the synchronous pulley to be larger than the width between the inner walls of the two fixed walls 101. In this way, when the sliding part 20 slides towards one side until the fixed terminal 202 abuts against the fixed wall 101, the sliding part 20 reaches the maximum distance that it can slide towards this side, so that the fixed terminal 202 and the fixed wall 101 jointly limit the size of the sliding distance of the sliding part 20.

[0041] Embodiment 2

[0042] In addition, as Figures 1 - 10 shown, as an application of the hinge involved in the foregoing solution, the present invention also provides a drifting screen window 60. The drifting screen window 60 is arranged on the preset window 1 through the hinge 70 in any one of the foregoing solutions. The number of hinges 70 is two. The main body of the drifting screen window 60 is connected to the gears in the two hinges through a synchronous shaft. The drifting screen window 60 can reciprocally slide along a direction perpendicular to the synchronous shaft along with the sliding part 20 of the hinge 70. During the movement, the gears in the two hinges rotate synchronously, so that the drifting screen window 60 can stably form a pocket position or close the pocket position on one side of the window 1. At the same time, the drifting screen window 60 can also rotate around the synchronous shaft to close or open the window 1 through the drifting screen window.

[0043] It should be noted that a hinge cavity 601 for accommodating the hinge is provided on the frame of the drifting screen window 60 parallel to the mounting base of the hinge 70. The synchronous shaft passes through the middle of the frame of the drifting screen window between the two hinges to connect the synchronous pulleys in the two hinges. When the drifting screen window 60 covers the window 1 or is in the closed state, during the sliding process of the drifting screen window 60 along with the hinge, the whole hinge 70 is always located within the hinge cavity 601, so that the hinge cannot be seen from the outside or only the end part of the hinge can be seen, which significantly improves the overall aesthetics of the drifting screen window.

[0044] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art of this technology, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements are all regarded as within the protection scope of the present invention.
