Detailed implementation manners

[0035] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiments of the present invention.

[0036] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the attached drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0038] An embodiment of the present invention discloses a side sliding door, which can be specifically referred to Figures 1 - 9 . This side sliding door includes a first door frame 1 and a second door frame 2, and an included angle is formed between the first door frame 1 and the second door frame 2; this side sliding door further includes a door body 3, one end of the door body 3 along its width is slidably arranged with the first door frame 1 and the other end is slidably arranged with the second door frame 2; a first damping member 4 is arranged at the top of the first door frame 1 and the first damping member 4 is arranged on the side close to the second door frame 2, a second damping member 5 is arranged at the top of the second door frame 2 and the second damping member 5 is arranged on the side close to the first door frame 1; a first acting member 6 and a second acting member 7 are arranged at the top of the door body 3, the first damping member 4 is located on the movement path of the first acting member 6, and the second damping member 5 is located on the movement path of the second acting member 7.

[0039] During specific use, the first doorframe 1 and the second doorframe 2 on this side shift door are respectively provided with a first damping member 4 and a second damping member 5 on the side close to each other. At the same time, a first acting member 6 and a second acting member 7 are provided on the door body 3, which act on the first damping member 4 and the second damping member 5 respectively to achieve buffering of the door body 3 on the first doorframe 1 and the second doorframe 2. During this buffering process, it can effectively prevent the pulley from being damaged due to excessive impact, and at the same time can effectively avoid collisions and reduce the generation of noise.

[0040] To better understand how to perform buffering, an example is given for illustration:

[0041] Taking the state where the door body 3 is in the closed state within the first doorframe 1 as the first state, and the state where the door body 3 is in the closed state within the second doorframe 2 as the second state, the state between the first state and the second state is the switching state. Among them, the side where the first doorframe 1 and the second doorframe 2 are close to each other is the near side, and the side where they are far from each other is the far side. In the first state, the door body 3 is parallel to the first doorframe 1, the first acting member 6 is located on the far side of the first doorframe 1, and the second acting member 7 is located on the near side of the second doorframe 2. In the second state, the door body 3 is parallel to the second doorframe 2, the first acting member 6 is located on the near side of the first doorframe 1, and the second acting member 7 is located on the far side of the second doorframe 2.

[0042] During the process of switching from the first state to the second state, the first acting member 6 will move from the far side to the near side of the first doorframe 1 until it contacts the first damping member 4, so that the first damping member 4 is compressed to generate a buffering effect, which can well prevent the door body 3 from colliding with the second doorframe 2 when closing the door. Similarly, during the process of switching from the second state to the first state, the second acting member 7 will move from the far side to the near side of the second doorframe 2 until it contacts the second damping member 5, so that the second damping member 5 is compressed to generate a buffering effect, which can well prevent the door body 3 from colliding with the first doorframe 1 when closing the door.

[0043] More importantly, it is found in actual use that when opening the door, for example, when in the first state, the second acting member 7 will compress the second damping member 5. When switching from the first state to the second state, the second acting member 7 will move from the near side to the far side of the second doorframe 2. At this time, the degree of compression of the second damping member 5 in the compressed state is reduced, which is equivalent to being in a pressure relief state, and can provide an additional acting force for the second acting member 7, making it easier to open the door. Similarly, when in the second state, the first acting member 6 will compress the first damping member 4. When switching from the second state to the first state, the first acting member 6 moves from the near side to the far side of the first doorframe 1. At this time, the degree of compression of the first damping member 4 in the compressed state is reduced, which is equivalent to being in a pressure relief state, and can provide an additional acting force for the first acting member 6, making it easier to open the door.

[0044] In summary, this side sliding door can achieve a good buffering effect between the door body 3, the first door frame 1, and the second door frame 2. During this buffering process, it can effectively prevent the pulleys from being damaged due to excessive impacts, and at the same time, it can effectively avoid collisions and reduce the generation of noise; also, it will be more labor-saving when opening the door.

[0045] This side sliding door further includes an extension member 8. One end of the extension member 8 is rotatably arranged on the door body 3 and the other end is provided with a second acting member 7, so that the first damping member 4 and the second damping member 5 are arranged staggeredly. In the actual assembly of this side sliding door, it is found that when closing the door, the door body 3 needs to be parallel to the first door frame 1 and the second door frame 2. Since the first damping member 4 and the second damping member 5 themselves have a certain volume, if a good closing effect of the door body 3 is to be achieved, the first damping member 4 and the second damping member 5 are prone to interference problems. For this reason, an extension member 8 is arranged between the door body 3 and the second acting member 7 to stagger the first damping member 4 and the second damping member 5 to avoid interference problems.

[0046] From Figure 8 it can be seen that after the extension member 8 is provided, when the door body 3 is in the first state, the extending length direction of the extension member 8 is perpendicular to the width direction of the door body 3 to ensure that the door body 3 is parallel to the first door frame 1, so that the door body 3 can be better closed within the first door frame 1.

[0047] In some embodiments, the first damping member 4 and / or the second damping member 5 can be a hydraulic damper or a pneumatic damper, which is not limited herein.

[0048] In some embodiments, a first sliding roller 31 is provided at the top of one end of the door body 3. The first acting member 6 and the first sliding roller 31 are coaxially arranged and arranged vertically. With such an arrangement, the sliding structure of the door body 3 - the first sliding roller 31 and the first acting member 6 can be assembled together, with a reasonable layout, making the structure more compact and reducing the occupied space.

[0049] Specifically, in order to make the sliding smoother, a guiding track can be assembled at the position of the first door frame 1 relative to the first sliding roller 31.

[0050] In some embodiments, at least two second sliding rollers 32 slidingly arranged with the second door frame 2 are provided at the top of the other end of the door body 3; a hollow area 81 is formed in the extension member 8, and at least two second sliding rollers 32 are arranged in the hollow area 81 and one of the second sliding rollers 32 is coaxially arranged at the rotation position of the extension member 8 and the door body 3. With such an arrangement, the sliding structure of the door body 3 - the second sliding rollers 32 and the second acting member 7 can be assembled together, with a reasonable layout, making the structure more compact and reducing the occupied space.

[0051] Specifically, in order to make the sliding smoother, a guiding track can be assembled at the position of the second door frame 2 relative to the second sliding roller 32.

[0052] In some embodiments, the second acting member 7 and another second sliding roller 32 are coaxially arranged and arranged vertically, and the second acting member 7 is arranged at the top of the extension member 8. With this arrangement, on the premise of ensuring sufficient sliding smoothness, the structure will be more compact, further reducing the occupied space.

[0053] In some embodiments, this side sliding door further includes a first housing 42 assembled on the first door frame 1. The first damping member 4 is fixed inside the first housing 42. A first hook 41 capable of sliding inside the first housing 42 is arranged at the telescopic end of the first damping member 4. The first housing 42 is provided with a first notch 421 for the first hook 41 to extend out. The first hook 41 is located on the movement path of the first acting member 6; within the area of the first notch 421, the first acting member 6 and the first hook 41 are engaged; outside the area of the first notch 421, the first acting member 6 and the first hook 41 are disengaged. With this arrangement, the structure can be made more compact, further reducing the occupied space.

[0054] For a better understanding of the cooperation between the first hook 41 and the first acting member 6, an example is given for illustration:

[0055] During the process of switching from the first state to the second state, the first acting member 6 will approach from the far side to the near side of the first door frame 1 until it snaps into the first hook 41 on the first damping member 4. The first acting member 6 drives the first hook 41 to move synchronously, so that the first damping member 4 is compressed to play a buffering role, which can well prevent the door body 3 from colliding with the second door frame 2 when closing the door. And when in the second state, the first acting member 6 compresses the first damping member 4 through the first hook 41. When switching from the second state to the first state, the first acting member 6 moves from the near side to the far side of the first door frame 1. At this time, it will drive the first hook 41 to move synchronously, so that the degree of compression of the first damping member 4 in the compressed state is reduced, which is equivalent to being in a pressure relief state, and can provide an additional acting force for the first acting member 6, making it easier to open the door.

[0056] It should be noted that within the area of the first notch 421 of the first housing 42, the first acting member 6 will remain in the state of being snapped into the first hook 41 on the first damping member 4 until the first acting member 6 leaves the area of the first notch 421 of the first housing 42, and the first acting member 6 will disengage from the first hook groove of the first hook 41.

[0057] It should also be noted that the structure for the first acting member 6 to disengage from the first hook 41 can be, for example, a first sliding groove is provided in the first housing 42, the first hook 41 slides along the first sliding groove, and an inflection point card slot is communicated with the first sliding groove. When the first hook 41 slides to the inflection point card slot, the first hook 41 rotates towards the inner side of the first housing 42 so that the first acting member 6 disengages from the first hook groove of the first hook 41. Moreover, the first hook 41 and the telescopic end of the first damping member 4 are pivotally connected to avoid interference. Alternatively, reference can also be made to the specific structure of the rotatable hook in the prior art.

[0058] Specifically, the first acting member 6 can be cylindrical, with a simple structure, which is convenient for manufacturing and production and reduces the manufacturing difficulty. At the same time, it can also better cooperate with the first hook 41.

[0059] It should be noted that the structure of the first acting member 6 is a cylindrical structure with a diameter slightly smaller than that of the first sliding roller 31, so that the first acting member 6 has a relatively large volume. When the first sliding roller 31 cooperates with the guiding track in the first door frame 1, the first acting member 6 will not contact the guiding track in the first door frame 1, and thus it is more convenient for the first acting member 6 to trigger the second damping member 5. Even if the first acting member 6 contacts the guiding track in the first door frame 1, since the circumferential side of the first acting member 6 is an arc surface, rolling contact will be formed, avoiding the increase in friction force and affecting the sliding.

[0060] In some embodiments, this side sliding door further includes a second housing 52 assembled in the second door frame 2. The second damping member 5 is fixed in the second housing 52. A second hook 51 capable of sliding in the second housing 52 is provided at the telescopic end of the second damping member 5. The second housing 52 is provided with a second notch 521 for the second hook 51 to extend out. The second hook 51 is located on the movement path of the second acting member 7. In the area of the second notch 521, the second acting member 7 and the second hook 51 are engaged. Outside the area of the second notch 521, the second acting member 7 and the second hook 51 are disengaged. With such a setting, the structure can be made more compact, further reducing the occupied space.

[0061] To better understand the cooperation between the second hook 51 and the second acting member 7, an example is given for illustration:

[0062] During the process of switching from the second state to the first state, the second acting member 7 will move from the far side to the near side of the second doorframe 2 until it snaps into the second hook 51 on the second damping member 5. The second acting member 7 drives the second hook 51 to move synchronously, so that the second damping member 5 is compressed to produce a buffering effect, which can well prevent the door body 3 from colliding with the first doorframe 1 when closing the door. Moreover, when in the first state, the second acting member 7 compresses the second damping member 5 through the second hook 51. When switching from the first state to the second state, the second acting member 7 will move from the near side to the far side of the second doorframe 2, and at this time, it will drive the second hook 51 to move synchronously, so that the degree of compression of the second damping member 5 in the compressed state is reduced, which is equivalent to being in a pressure relief state, and can provide an additional acting force for the second acting member 7, making it easier to open the door.

[0063] It should be noted that within the area of the second notch 521 of the second housing 52, the second acting member 7 will remain in the state of being snapped into the second hook groove of the second hook 51 on the second damping member 5 until the second acting member 7 leaves the area of the second notch 521 of the second housing 52, and the second acting member 7 will disengage from the second hook groove of the second hook 51.

[0064] It should also be noted that the structure for the second acting member 7 to disengage from the second hook groove of the second hook 51, for example, a second sliding groove is provided in the second housing 52, and the second hook 51 slides along the second sliding groove. There is also an inflection point card slot communicated with the second sliding groove. When the second hook 51 slides to the inflection point card slot, the second hook 51 can rotate so that the second acting member 7 disengages from the second hook groove of the second hook 51. Moreover, the second hook 51 and the telescopic end of the second damping member 5 are pivotally connected to avoid interference. Or, reference can also be made to the specific structure of the rotatable hook in the prior art.

[0065] Specifically, the second acting member 7 can be cylindrical, with a simple structure, which is convenient for manufacturing and production and reduces the manufacturing difficulty; at the same time, it can also better cooperate with the second hook 51.

[0066] It should be noted that the structure of the second acting member 7 is a cylindrical structure with a diameter slightly smaller than that of the second sliding roller 32, so that the second acting member 7 has a larger volume. Thus, when the second sliding roller 32 cooperates with the guiding track in the second doorframe 2, the second acting member 7 will not contact the guiding track in the second doorframe 2, and further, it is more convenient for the second acting member 7 to trigger the second damping member 5. Even if the second acting member 7 contacts the guiding track in the second doorframe 2, because the circumferential side of the second acting member 7 is an arc surface, rolling contact will be formed, avoiding an increase in friction force and affecting sliding.

[0067] In some of these embodiments, the angle between the first door frame 1 and the second door frame 2 is 90°. With such an arrangement, the structure can be made more compact, the occupied area can be further reduced, and it can be applied to small-area application scenarios, such as bathrooms, toilets, etc.

[0068] In some of these embodiments, the first damping member 4 and the second damping member 5 are located at the same horizontal height and are vertically arranged, and the orthographic projection of the second damping member 5 in the direction towards the first damping member 4 is located within the occupied space of the first damping member 4. With such an arrangement, the structure is made more compact and the occupied area can be further reduced.

[0069] In some of these embodiments, a first installation opening 11 is provided at the top of the first door frame 1, and the first damping member 4 is installed at the guiding track inside the first door frame 1 through the first installation opening 11; a second installation opening 21 is provided at the top of the second door frame 2, and the second damping member 5 is installed at the guiding track inside the second door frame 2 through the second installation opening 21. With such an arrangement, the detachable installation of the first damping member 4 and the second damping member 5 is realized, avoiding the inconvenience of having to disassemble the first door frame 1 and the second door frame 2 when maintaining the first damping member 4 and the second damping member 5. Only by disassembling the first damping member 4 and the second damping member 5 from the first installation opening 11 and the second installation opening 21 respectively can maintenance be carried out, greatly improving the convenience of installing and maintaining the first damping member 4 and the second damping member 5.

[0070] In some of these embodiments, a first cover plate 43 is detachably installed on the first damping member 4, and the first cover plate 43 is detachably installed at the first installation opening 11; a second cover plate 53 is detachably installed on the second damping member 5, and the second cover plate 53 is detachably installed at the second installation opening 21. With such an arrangement, the detachable installation of the first damping member 4 and the second damping member 5 is realized through a simpler structure.

[0071] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
