TECHNICAL FIELD
[0001] The utility model belongs to hinge field, concretely relates to a double track guide formula hinge structure. BACKGROUND
[0002] Hinge is a mechanical device used to connect two solids and allow relative rotation between them.
[0003] At present, there are various types of hinges on the market, which are widely used in furniture and electrical equipment. The conventional hinge generally includes a base provided on the side plate of a cabinet, a rotating arm provided on the door plate and rotationally connected with the base, and a built-in spring (or damper) for realizing buffer closing.
[0004] However, in actual use, the existing hinge has the following technical defects:
[0005] 1. In order to prevent the door plate from interfering with the side plate during opening and closing, the rotating arm usually needs to be provided with sufficient rotating radius, thereby resulting in large overall volume of the hinge, high cost, and large spacing between the door plate and the side plate when the door plate is completely opened, which is prone to shaking under external force.
[0006] 2. The rotating arm only rotates around the pivot shaft on the base, lacks limiting and guiding, and thus the door plate has poor opening and closing feel. SUMMARY
[0007] The utility model wants to solve the technical problem of overcoming the prior art, and provides an improved double track guide formula hinge structure.
[0008] To solve the above technical problems, the utility model adopts the following technical scheme:
[0009] A double track guide formula hinge structure, which comprises a fixed seat provided on the side plate of a cabinet, a movable seat provided on the door plate, and a rotating arm with one end fixed on the movable seat, wherein the fixed seat is provided with a pivot shaft track and an auxiliary track; the other end of the rotating arm is provided with a pivot shaft and an auxiliary shaft arranged side by side and spaced apart, the pivot shaft and the auxiliary shaft are correspondingly rotated and slidably arranged on the pivot shaft track and the auxiliary track, with the opening and closing movement of the door plate, the rotating arm takes the pivot shaft center line as the rotating reference line, the pivot shaft and the auxiliary shaft synchronously reciprocate along the pivot shaft track and the auxiliary track, the pivot shaft forms a first position away from the edge of the fixed seat and a second position close to the edge of the fixed seat, and the movable seat is kept apart from the fixed seat.
[0010] According to one specific implementation and preferred aspect of the utility model, the pivot shaft track is a strip-shaped track slot extending towards the edge of the fixed seat, and the pivot shaft moves to the two ends of the pivot shaft track when in the first position and the second position. Here, the two ends of the pivot shaft track constitute the limit positions of the pivot shaft movement track, thereby further improving the stability of the door plate when completely opened or closed.
[0011] According to another specific implementation and preferred aspect of the present application, as the door panel is opened or closed, the auxiliary shaft moves along the auxiliary track towards the direction of approaching or moving away from the edge of the fixed base, and the pivot synchronously moves from the first position to the second position and then returns to the first position.
[0012] Preferably, the auxiliary track is a V-shaped track groove with an opening facing the edge of the fixed base and a turning point formed from the middle portion, when the auxiliary shaft is located at the two ends of the auxiliary track, the pivot is in the first position; when the auxiliary shaft passes through the turning point, the pivot is in the second position. That is, when the auxiliary shaft moves from one end of the auxiliary track to the other end, the pivot reciprocates between the first position and the second position once.
[0013] Preferably, when the auxiliary shaft moves to the end of the auxiliary track close to the edge of the fixed base, the door panel is synchronously opened and flush with the side panel.
[0014] According to another specific implementation and preferred aspect of the present application, the pivot track and the auxiliary track form a guide group, the guide group has two and is located on the opposite sides of the fixed base, and the pivot and the auxiliary shaft are respectively connected to the corresponding pivot track and auxiliary track from the two ends. Here, the motion stability is improved.
[0015] According to another specific implementation and preferred aspect of the present application, the hinge structure further comprises an elastic member arranged on the fixed base, wherein the elastic member elastically abuts against the pivot and / or the auxiliary shaft, and when the door panel is closed or opened, the elastic member correspondingly forms an elastic force for opening or closing the auxiliary door panel.
[0016] Preferably, the elastic member is a torsional spring with one end fixed on the fixed base, when the door panel is closed, the other end of the torsional spring abuts against the auxiliary shaft; when the door panel is opened, the other end of the torsional spring abuts against the pivot. That is, when the door panel is closed, the other end of the torsional spring abuts against the auxiliary shaft in the direction of the edge of the fixed base, so that the rotating arm has a motion trend of rotating in the opening direction; when the door panel is opened, the other end of the torsional spring abuts against the pivot in the direction of the edge of the fixed base, so that the rotating arm has a motion trend of rotating in the closing direction. Here, as the door panel is opened and closed, the positions of the pivot and the auxiliary shaft in the motion are changed in turn to abut against the end of the torsional spring, so that the elastic force formed by the torsional spring is switched between opening the auxiliary door panel and closing the auxiliary door panel, making the door panel opening and closing more labor-saving.
[0017] Preferably, the rotating arm comprises an arm body, a first bent arm and a second bent arm respectively bent from the two ends of the arm body to one side, wherein the pivot and the auxiliary shaft are arranged on the first bent arm, and the second bent arm is fixedly connected with the movable base.
[0018] In addition, the hinge structure further comprises a damper installed on the fixed seat, and as the door plate is closed, the arm body gradually abuts against the telescopic end of the damper, and the damper synchronously forms damping to slow down the closing movement trend of the door plate.
[0019] Thanks to the above technical solutions, the present application has the following advantages over the prior art:
[0020] In order to prevent the door plate from interfering with the side plate during opening and closing, the rotating arm of the hinge usually needs to be provided with sufficient rotating radius, thereby resulting in large overall volume and high cost of the hinge, and when the door plate is fully opened, the distance between the door plate and the side plate is large, and the door plate is prone to shaking under external force; meanwhile, the rotating arm only rotates around the pivot on the base, and lacks limiting and guiding, thereby resulting in poor opening and closing feeling of the door plate; the structure of the double-track guiding type hinge structure is designed as a whole, and the deficiencies and defects of the prior art are ingeniously solved; after the hinge structure is adopted, the pivot at one end of the rotating arm and the auxiliary shaft are correspondingly arranged on the pivot track and the auxiliary track for rotating and sliding, respectively, and as the door plate is opened and closed, the rotating arm keeps the center line of the pivot as the rotating reference line, the pivot and the auxiliary shaft synchronously reciprocate along the pivot track and the auxiliary track to form movement guiding, and the pivot forms the second position away from the edge of the fixed seat and close to the edge of the fixed seat in the movement of the pivot track, so as to realize that the movable seat is separated from the fixed seat during the turning process to avoid interference, and the pivot is reset after turning to reduce the distance between the movable seat and the fixed seat, thereby realizing compact structure. Therefore, compared with the prior art, on the one hand, the position of the pivot is changed to avoid interference between the movable seat and the fixed seat during the rotation of the rotating arm around the pivot, to reduce the active space required for rotation, to effectively reduce the volume of the hinge, to reduce the cost, and at the same time, the distance between the door plate and the side plate is small after the door plate is opened, which is conducive to improving the stability of the door plate; on the other hand, the movement guiding is formed by the pivot track and the auxiliary track synchronously to the pivot and the auxiliary shaft, thereby effectively improving the opening and closing quality of the door plate and enhancing the user experience.

Here, the flatness of the surfaces of the cabinet side plate and the door plate is achieved, foreign matter is prevented from being stuck in the hinge, and the aesthetic appearance is improved.
[0039] In this example, one end of the rotating arm 3 is fixed on the movable seat 2, and the other end is provided with the pivot s1 and the auxiliary shaft s2 arranged side by side and spaced apart, the fixed seat 1 is provided with the pivot track g1 and the auxiliary track g2, the pivot s1 and the auxiliary shaft s2 are correspondingly arranged on the pivot track g1 and the auxiliary track g2, and the rotating arm 3 is arranged on the movable seat 2. With the opening and closing movement of the door plate B2, the rotating arm 3 takes the center line of the pivot s1 as the rotating reference line, the pivot s1 and the auxiliary shaft s2 are synchronously reciprocated along the pivot track g1 and the auxiliary track g2, the pivot s1 forms the first position away from the edge of the fixed seat 1 and the second position close to the edge of the fixed seat 1, and the movable seat 2 is kept apart from the fixed seat 1. It needs to be particularly pointed out that the edge of the fixed seat 1 is the edge of the fixed seat 1 close to the movable seat 2.
[0040] In some specific embodiments, the rotating arm 3 includes an arm body 30, a first bending arm 31 and a second bending arm 32 respectively bent to one side from both ends of the arm body 30, wherein the pivot s1 and the auxiliary shaft s2 are arranged side by side on the first bending arm 31 along the bending direction of the first bending arm 31, and the second bending arm 32 is fixedly connected with the movable seat 2.
[0041] In order to facilitate implementation, the pivot track g1 and the auxiliary track g2 constitute a guide group, the guide group has two and is located on the opposite sides of the fixed seat 1, and the pivot s1 and the auxiliary shaft s2 are respectively connected on the corresponding pivot track g1 and the auxiliary track g2 from both ends. Here, the motion stability is improved.
[0042] The following describes one of the guide groups, and the other structure is also clear.
[0043] In this example, the pivot track g1 is a strip-shaped track groove extending to the edge direction of the fixed seat 1, and the pivot s1 moves to both ends of the pivot track g1 when in the first position and the second position. Here, the limit positions of the pivot movement track are constituted by both ends of the pivot track, so as to further improve the stability of the door plate when fully opened or closed.
[0044] Meanwhile, as the door panel opens or closes, the auxiliary shaft s2 moves along the auxiliary track g2 towards the edge of the fixed base 1, and the pivot shaft s1 moves synchronously from the first position to the second position and then returns to the first position; the auxiliary track g2 is a V-shaped track slot with an opening facing the edge of the fixed base 1 and a turning point formed in the middle, when the auxiliary shaft s2 is located at both ends of the auxiliary track g2, the pivot shaft s1 is in the first position; when the auxiliary shaft s2 passes through the turning point, the pivot shaft s1 is in the second position. That is, when the auxiliary shaft moves from one end of the auxiliary track to the other end, the pivot shaft reciprocates between the first position and the second position once. As for the length of the two sections of the auxiliary track g2 and the angle at the turning point, the length of the pivot track g1, they are calculated based on the actual size of the rotating arm, the distance between the auxiliary shaft and the pivot shaft, which will not be described here.
[0045] Further, when the auxiliary shaft s2 moves to the end of the auxiliary track g2 close to the edge of the fixed base 1, the door panel B2 opens synchronously and is flush with the side panel B1.
[0046] In this example, the damper 4 is installed on the fixed base 1, and as the door panel B2 closes, the arm body 30 gradually contacts the telescopic end of the damper 4, and the damper 4 synchronously forms a damping to slow down the closing movement of the door panel B2. The damper 4 is a commercially available product.
[0047] In addition, the hinge structure further comprises a resilient member 5 arranged on the fixed base 1, wherein the resilient member 5 elastically contacts the pivot shaft s1 and / or the auxiliary shaft s2, and when the door panel B2 is closed or opened, the resilient member 5 correspondingly forms an elastic force to open or close the auxiliary door panel.

Here, as the door panel opens and closes, the position of the pivot shaft and the auxiliary shaft in the movement is changed in turn to contact the end of the torsional spring, so as to switch the elastic force formed by the torsional spring between opening the auxiliary door panel and closing the auxiliary door panel. In order to ensure that the torsional spring contacts the auxiliary shaft s2 when the door panel B1 is closed, a protruding block is arranged at the end of the auxiliary shaft s2, and the torsional spring contacts the protruding block.
[0049] In summary, after adopting the hinge structure, the pivots and the auxiliary shafts at one end of the rotating arm are correspondingly arranged to rotate and slide on the pivot track and the auxiliary track, with the rotating arm keeping the center line of the pivot as the rotating reference line, the pivots and the auxiliary shafts reciprocating along the pivot track and the auxiliary track to form a motion guide, and the pivots moving away from the edge of the fixed seat and moving close to the edge of the fixed seat to form a second position, so as to realize the separation of the movable seat and the fixed seat to avoid interference in the turning process, and the pivots resetting to reduce the distance between the movable seat and the fixed seat after turning, so as to realize the compact structure.
