Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a buffer mechanism and hinge with a single-sided damper. Background Technology

[0002] Hinges are commonly used to connect the cabinet body and doors of wardrobes or cabinets, enabling the doors to open and close. As people's pursuit of quality of life and aesthetic appreciation of home products continues to increase, they are increasingly inclined towards products that are exquisite and compact.

[0003] In existing technology, to achieve a bidirectional buffering effect in the hinge, the damping component consists of a damper and a spring connected in series, with the central axes of the damper and spring collinear. However, this arrangement increases the length of the hinge (in the direction of the spring's central axis), resulting in a larger hinge size. If the central axes of the damper and spring are not collinear and are distributed side-by-side in the width direction of the hinge (perpendicular to the spring's central axis), while reducing the hinge length, the spring force and the damping force of the damper cannot act in the same straight line. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a buffer mechanism and hinge with a single-sided damper.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a buffer mechanism with a single-sided damper, comprising: The seat body has a movable groove and guide grooves and receiving grooves respectively arranged on both sides of the movable groove. The movable groove is connected to the guide groove and the receiving groove respectively. A hydraulic damper is provided in the receiving groove. A connecting rod is movably disposed within the movable groove, with one end of the connecting rod passing through the groove wall and a spring sleeved on the connecting rod; A transmission component is located at the other end of the connecting rod. One end of the transmission component is provided with a guide structure, which is guided and engaged with the guide groove. The other end of the transmission component abuts against one end of the hydraulic damper.

[0006] As a further embodiment, the transmission component includes a first abutment plate, a guide structure fixed to one end of the first abutment plate, a connecting plate fixed to the other end of the first abutment plate, and a second abutment plate fixed to one end of the connecting plate. The other end of the connecting rod can abut against the first abutment plate, and one end of the hydraulic damper abuts against the second abutment plate.

[0007] As a further embodiment, the guide structure includes a base plate and side plates integrally formed on both sides of the base plate. The base plate abuts against the bottom of the guide groove, and the side plates on both sides abut against the two side walls of the guide groove, and the base plate or one of the side plates is fixedly connected to the first abutment plate.

[0008] As a further embodiment, the connecting plate is attached to the groove wall on one side of the movable groove.

[0009] As a further embodiment, the connecting rod includes a rod portion and a pressing portion fixed to one end of the rod portion. The end of the rod portion away from the pressing portion passes through the groove wall of the movable groove. The pressing portion can abut against the first abutment plate, and the spring is sleeved on the rod portion.

[0010] As a further embodiment, the buffer mechanism further includes a movable plate, a fixed plate, a first eccentric wheel, and a second eccentric wheel. The movable plate is located between the fixed plate and the base and is fastened to the base. The bottom of the first eccentric wheel is riveted to the fixed plate. The movable plate has a first oblong hole that engages with the first eccentric wheel, allowing the movable plate to move relative to the fixed plate in the vertical direction. The bottom of the second eccentric wheel is riveted to the movable plate. The base has a second oblong hole that engages with the second eccentric wheel, allowing the base to move relative to the movable plate in the front-back direction.

[0011] As a further embodiment, the fixed plate has openings at both its front and rear ends, and the movable plate has guide hooks bent at both ends. The guide hooks at both ends of the movable plate are respectively engaged in the openings at both ends of the fixed plate, so that the movable plate remains stationary relative to the fixed plate in the front-back and left-right directions, and can slide relative to the fixed plate in the up-down direction.

[0012] This utility model also provides a hinge, including the above-mentioned buffer mechanism with a single-sided damper, and further including a hinge cup and a hinge arm. One end of the hinge arm is connected and fixed to the seat body, and the other end of the hinge arm is hinged to the hinge cup through a first hinge member and a second hinge member respectively. One end of the connecting rod passing through the wall of the movable groove is hinged to the middle of the second hinge member through a third hinge member.

[0013] The beneficial effects of this utility model are as follows: The base has a movable groove and guide grooves and receiving grooves respectively located on both sides of the movable groove. The movable groove is positioned between the guide groove and the receiving groove, allowing the spring and hydraulic damper to be distributed along the vertical direction. Furthermore, the central axis of the spring and the central axis of the hydraulic damper are not on the same straight line, thus shortening the length of the base in the front-back direction and making the overall structure more compact. Simultaneously, one end of the transmission component has a guide structure that guides and cooperates with the guide groove. The guide structure can move along the front-back direction within the guide groove, thus restricting the movement direction of the transmission component and allowing it to move along the front-back direction. The other end of the transmission component abuts against one end of the hydraulic damper, thereby transmitting the damping force of the hydraulic damper to the connecting rod through the transmission component. The guide structure and guide groove ensure that both the damping force of the hydraulic damper and the elastic force of the spring can act on the connecting rod, meaning that the damping force and the elastic force can act on the same straight line.

Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] Example 1 As attached Figure 1-5 As shown, this embodiment provides a buffer mechanism with a single-sided damper, including a base 1, a connecting rod 3, and a transmission component 5.

[0019] As attached Figure 3-4 As shown, the base 1 has a movable groove 11 and guide grooves 12 and receiving grooves 13 respectively disposed on both sides of the movable groove 11. The movable groove 11 communicates with the guide grooves 12 and the receiving grooves 13. The movable groove 11 is located in the middle of the base 1 and between the guide grooves 12 and the receiving grooves 13. A hydraulic damper 2 is disposed in the receiving groove 13. At least one hydraulic damper 2 is placed therein, but in this embodiment, it is preferable to place only one. The hydraulic damper 2 plays a buffering role, thereby forming a buffer mechanism with a single-sided damper.

[0020] As attached Figure 3As shown, the connecting rod 3 is movably disposed in the movable groove 11. Specifically, the connecting rod 3 can move along the front-back direction in the movable groove 11, and one end of the connecting rod 3 passes through the groove wall of the movable groove 11. A spring 4 is sleeved on the connecting rod 3. Since the receiving groove 13 is disposed on one side of the movable groove 11, the spring 4 and the hydraulic damper 2 are distributed along the vertical direction, and the central axis of the spring 4 and the central axis of the hydraulic damper 2 are not on the same straight line, thereby shortening the length of the seat 1 in the front-back direction and making the whole unit more compact.

[0021] As attached Figure 3-4 As shown, the transmission component 5 is located at the other end of the connecting rod 3. Specifically, the transmission component 5 is either fixedly connected to or abuts against the other end of the connecting rod 3. When the transmission component 5 is fixedly connected to the other end of the connecting rod 3, the forward movement of the connecting rod 3 will cause the transmission component 5 to compress the spring 4, thereby creating a rearward elastic force on the connecting rod 3 and the transmission component 5. The piston rod of the hydraulic damper 2 will then extend and continue to act on the transmission component 5. When the transmission component 5 abuts against the other end of the connecting rod 3, as the connecting rod 3 moves forward, the piston rod of the hydraulic damper 2 will extend and continue to act on the transmission component 5, thereby pushing the transmission component 5 to continuously abut against the other end of the connecting rod 3. In both of these methods, the transmission component 5 continuously acts on the connecting rod 3.

[0022] As attached Figure 3-5 As shown, one end of the transmission component 5 is provided with a guide structure 51, which is guided and engaged with the guide groove 12. The guide structure 51 can move in the guide groove 12 along the front-back direction, thereby restricting the movement direction of the transmission component 5 and allowing it to move along the front-back direction. The other end of the transmission component 5 abuts against one end of the hydraulic damper 2, thereby transmitting the damping force of the hydraulic damper 2 to the connecting rod 3 through the transmission component 5. Furthermore, the guide structure 51 is guided and engaged with the guide groove 12, so that the damping force of the hydraulic damper 2 and the elastic force of the spring 4 can both act on the connecting rod 3, that is, the damping force and the elastic force can act on the same straight line.

[0023] In this embodiment, the seat 1 has a movable groove 11 and guide grooves 12 and receiving grooves 13 respectively disposed on both sides of the movable groove 11. The movable groove 11 is located between the guide grooves 12 and the receiving grooves 13, so that the spring 4 and the hydraulic damper 2 are distributed along the vertical direction, and the central axis of the spring 4 and the central axis of the hydraulic damper 2 are not on the same straight line, thereby shortening the length of the seat 1 in the front-back direction and making the whole unit smaller. At the same time, one end of the transmission member 5 is provided with a guide structure 51, which guides and cooperates with the guide groove 12. The guide structure 51 can move in the guide groove 12 along the front-back direction, thereby restricting the movement direction of the transmission member 5 and making it move along the front-back direction. The other end of the transmission member 5 abuts against one end of the hydraulic damper 2, thereby transmitting the damping force of the hydraulic damper 2 to the connecting rod 3 through the transmission member 5. The guide structure 51 guides and cooperates with the guide groove 12, so that the damping force of the hydraulic damper 2 and the elastic force of the spring 4 can both act on the connecting rod 3, that is, the damping force and the elastic force can act on the same straight line.

[0024] Further details are attached. Figure 3-5 As shown, the transmission component 5 includes a first abutment plate 52, a guide structure 51 fixed to one end of the first abutment plate 52, a connecting plate 53 fixed to the other end of the first abutment plate 52, and a second abutment plate 54 fixed to one end of the connecting plate 53. Specifically, the guide structure 51 and the connecting plate 53 are both perpendicular to the first abutment plate 52, and both the guide structure 51 and the connecting plate 53 are in front of the first abutment plate 52. The second abutment plate 54 is perpendicular to the connecting plate 53. The other end of the connecting rod 3 can abut against the first abutment plate 52, and one end of the hydraulic damper 2 abuts against the second abutment plate 54. The damping force of the hydraulic damper 2 is transmitted to the connecting rod 3 through the second abutment plate 54, the connecting plate 53, and the first abutment plate 52 in sequence. After the guide structure 51 and the guide groove 12 guide and cooperate, the damping force of the hydraulic damper 2 acts in the front-rear direction and acts in the same straight line as the elastic force of the spring 4.

[0025] It is worth mentioning that, as shown in the attached document Figure 3-5 As shown, the guide structure 51 includes a base plate 511 and side plates 512 integrally formed on both sides of the base plate 511. The base plate 511 abuts against the bottom of the guide groove 12, and the two side plates 512 abut against the two side walls of the guide groove 12 respectively. The base plate 511 or one of the side plates 512 is fixedly connected to the first abutment plate 52, so that the guide structure 51 fully cooperates with the guide groove 12, and the transmission component 5 moves in the front-back direction.

[0026] Furthermore, as attached Figure 3-4 As shown, the connecting plate 53 abuts against the groove wall on one side of the movable groove 11, thereby guiding the other end of the first abutment plate 52, so that the transmission component 5 moves in the front-back direction, and further so that the damping force of the hydraulic damper 2 and the elastic force of the spring 4 can act in the same straight line.

[0027] In some embodiments, as shown in the appendix Figure 3 As shown, the connecting rod 3 includes a rod portion 31 and a pressing portion 32 fixed to one end of the rod portion 31. The end of the rod portion 31 away from the pressing portion 32 passes through the groove wall of the movable groove 11. The pressing portion 32 can abut against the first abutment plate 52. The spring 4 is sleeved on the rod portion 31. When the connecting rod 3 moves forward, the pressing portion 32 presses the spring 4 and prevents the spring 4 from disengaging from the rod portion 31. One end of the spring 4 abuts against the groove wall of the movable groove 11, and the other end of the spring 4 abuts against the pressing portion 32, thereby generating a rearward elastic force on the connecting rod 3. At the same time, the piston rod of the hydraulic damper 2 returns to its original position and extends, continuously acting on the second abutment plate 54, thereby pushing the first abutment plate 52 of the transmission member 5 to continuously abut against the pressing portion 32 of the connecting rod 3.

[0028] Based on the above, as shown in the appendix Figure 6-10 As shown, the buffer mechanism also includes a movable plate 6, a fixed plate 7, a first eccentric wheel 8, and a second eccentric wheel 81. The movable plate 6 is located between the fixed plate 7 and the base 1, and is movably mounted on the base 1. Specifically, see attached... Figure 4 , 10 As shown, locking protrusions 63 can be provided at both the upper and lower ends of the movable piece 6, and corresponding locking grooves 15 can be provided on the base 1, so that the locking protrusions 63 can be engaged into the locking grooves 15, thereby enabling the movable piece 6 to be movably mounted on the base 1 and preventing the connecting rod 3, spring 4, transmission component 5 and hydraulic damper 2 from detaching from the base 1. The fixed piece 7 is used to fix it to the inner wall of the cabinet a. The bottom of the first eccentric wheel 8 is riveted to the fixed piece 7, which allows the first eccentric wheel 8 to rotate relative to the fixed piece 7, and also creates an interaction force between the fixed piece 7 and the movable piece 6. The movable piece 6 has a first oblong hole 61 that matches the first eccentric wheel 8. The first eccentric wheel 8 rotates in the first oblong hole 61, thereby allowing the movable piece 6 to move in the vertical direction relative to the fixed piece 7.

[0029] As attached Figure 7 , 9 As shown, the bottom of the second eccentric wheel 81 is riveted to the movable piece 6, which allows the second eccentric wheel 81 to rotate relative to the movable piece 6, and also creates an interaction force between the base 1 and the movable piece 6. The base 1 has a second oblong hole 14 that mates with the second eccentric wheel 81. The second eccentric wheel 81 rotates within the second oblong hole 14, allowing the base 1 to move relative to the movable piece 6 in the front-back direction.

[0030] Furthermore, as attached Figure 1As shown, the fixed plate 7 has openings 71 at both the front and rear ends, and the movable plate 6 has guide hooks 62 bent at both ends. The guide hooks 62 at both ends of the movable plate 6 are respectively locked in the openings 71 at both ends of the fixed plate 7, so that the movable plate 6 remains stationary relative to the fixed plate 7 in the front-back and left-right directions, and can slide relative to the fixed plate 7 in the up-down direction, thereby allowing the base 1 to slide relative to the fixed plate 7 in the up-down direction.

[0031] Example 2 As attached Figure 6-11 As shown, this embodiment provides a hinge, including a buffer mechanism with a single-sided damper as described in Embodiment 1 above, and further including a hinge cup 9 and a hinge arm 91. The hinge cup 9 is fixed to the door body b. One end of the hinge arm 91 is connected and fixed to the base 1, and the other end of the hinge arm 91 is hinged to the hinge cup 9 through a first hinge member 10 and a second hinge member 101. Specifically, one end of the first hinge member 10 and the second hinge member 101 are hinged to the hinge arm 91 through a pin, and the other end of the first hinge member 10 and the second hinge member 101 are hinged to the hinge cup 9 through a pin. One end of the connecting rod 3 passing through the wall of the movable groove 11 is hinged to the middle of the second hinge member 101 through a third hinge member 102. Specifically, one end of the third hinge 102 is hinged to one end of the connecting rod 3 through the wall of the movable groove 11 via a pin, and the other end of the third hinge 102 is hinged to the middle of the second hinge 101 via a pin, so that the hinge cup 9 can swing relative to the seat 1, thereby opening and closing the door b, and thus driving the connecting rod 3 to move relative to the seat 1 in the front and back direction.
