In the case where a directional instruction is involved in the embodiment of the present invention, the directional instruction is merely used to explain the relative positional relationship, movement condition, etc. between the components in a specific posture, and if the specific posture is changed, the directional instruction is changed accordingly.

In addition, if there is a description of "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and/or" as it appears throughout is meant to include three side-by-side schemes, for example, "A and/or B", including the A scheme, or the B scheme, or the scheme where A and B meet at the same time.

Referring to fig. 1, the present invention provides a shower room device 1000, where the shower room device 1000 may be an integrated shower room including a shower room door 200, walls and floors, may include only a shower room wall provided with the door 200, and may include only a shower room door 200 and a part of fittings of a door 200 fixing member. In one embodiment, the shower enclosure assembly 1000 includes a frame assembly for connecting a load-bearing structure such as a wall, and a door leaf 200 mounted to the frame assembly, the door leaf 200 being rotatably mounted to the frame assembly. The frame assembly and the door leaf 200 are not limited in material and shape, and the frame assembly may be made of corrosion-resistant and rust-resistant materials such as aluminum alloy, and the door leaf 200 may be made of materials such as aluminum alloy and glass.

In the present invention, the vertical direction means a direction extending substantially parallel to the gravitational force, and the lateral direction means a direction extending substantially in the horizontal direction. And the description of directionality in the present invention is only applicable to the state of the product when it is normally used after installation, excluding the state of the product during production, transportation and installation. In this embodiment, the frame assembly at least includes an upper frame 1001 and a lower frame 1002 that are disposed at intervals in the vertical direction, the upper frame 1001 and the lower frame 1002 extend in the lateral direction, and the upper frame 1001 is located above the lower frame 1002, typically, two ends of the upper frame 1001 are fixed on a wall, the lower frame 1002 is fixed on the ground, and the side edge of the door leaf 200 may be further provided with a fixing fan in an abutting manner, and the fixing fan may also be made of materials such as aluminum alloy and glass, so as to form a shower room wall together with the door leaf 200, and form a shower space together with an inherent building wall. The door 200 may be rotatably mounted on the frame assembly in various manners, in this embodiment, the upper end of the door 200 is rotatably connected to the upper frame 1001, and the lower end of the door 200 is rotatably connected to the lower frame 1002, so that the door can be opened and closed according to the requirement of use.

In the present invention, the door leaf 200 is mounted to the frame assembly through the door closer assembly 100, so that the door leaf 200 has a closed state maintained, and the closing speed of the door leaf 200 is controlled through buffering during the closing process, thereby preventing the door leaf 200 from being collided, making noise, or being damaged. In this embodiment, referring to fig. 1 to 3 in combination, the door closer assembly 100 includes a power unit 10 and a resistance unit 20 which are separately provided, the upper end of the door leaf 200 is rotatably mounted to the upper frame 1001 through one of the power unit 10 or the resistance unit 20, and the lower end of the door leaf 200 is rotatably mounted to the lower frame 1002 through the other of the power unit 10 and the resistance unit 20.

Conventional door closers are typically configured to integrate drive and buffer functions, and are typically configured to be positioned on top of the door leaf 200, avoiding long-term immersion in water from affecting the service life of the door closers. However, this arrangement of the door closer results in a larger overall size of the door closer, and the upper frame 1001 must necessarily have a higher or thicker size to accommodate the door closer with driving and cushioning functions. This results in the shower enclosure assembly 1000 not meeting the modern extremely simple design requirements, being aesthetically unappealing, and the door closer integrating more functions, resulting in a complex internal structure, which is inconvenient to install and maintain. Therefore, the door closer assembly 100 provided by the invention comprises the power set 10 and the resistance set 20 which are arranged in a split manner, and the power set 10 and the resistance set 20 are respectively arranged at the upper end and the lower end of the door leaf 200, so that the sizes of the door closers at the two ends of the door leaf 200 are correspondingly reduced, and the door closer assembly can be arranged in a frame with smaller height, so that the appearance of the shower room frame is lighter, thinner and more attractive. The specific form of the power pack 10 and the resistance pack 20 mounted to the frame assembly is not limited, and in this embodiment, referring to fig. 2 to 5, it can be seen that the main bodies of the power pack 10 and the resistance pack 20 are substantially hidden in the upper frame 1001 or the lower frame 1002, and only the first clamping member 15 and the second clamping member 25 are exposed and connected and fixed to the door leaf 200. In addition, in the door closer assembly 100, the power unit 10 separately provides a function of driving the door leaf 200 to close, the resistance unit 20 separately provides a buffer function of slowing down the closing speed of the door leaf 200, and the two are matched together to control the opening and closing speed of the door leaf 200, so that the functions of the components of the door closer assembly 100 are relatively single, the structure is relatively simple, and the installation and the maintenance are easy.

In the present invention, the power unit 10 is used to provide a driving force for driving the door leaf 200 to rotate in the closing direction. In this embodiment, referring to fig. 6, 7, 10 and 11, the power unit 10 includes a first housing 11, a first rotating member and a driving member 13 disposed on the first housing 11, where the first rotating member is mounted on the first housing 11 and is used to connect to a first end of the door leaf 200, so that the first rotating member has a first rotating position corresponding to an open state of the door leaf 200 and a second rotating position corresponding to a closed state of the door leaf 200. Specifically, the first rotating member is rotatably mounted to the first housing 11 about its own rotation axis, and the door leaf 200 is connected to the first rotating member such that the first rotating member rotates with the rotational motion of the door leaf 200. The driving member 13 is in driving connection with the first rotating member to provide a restoring force for driving the first rotating member to rotate toward the second rotating position in a rotation stroke of the first rotating member. In this embodiment, the driving member 13 may be an elastic member, and the transmission connection manner between the driving member 13 and the first rotating member is not limited, for example, a link transmission, an abutting transmission, a rack-and-pinion engagement transmission, etc., so long as the driving force provided by the driving member 13 can be transmitted to the first rotating member through transmission, so as to drive the first rotating member to rotate, thereby driving the door leaf 200 to rotate. In this way, when the door leaf 200 rotates from the closed state to the open state, the first rotating member rotates correspondingly from the second rotating position to the first rotating position, and in this stroke, the driving member 13 in driving connection with the first rotating member provides a restoring force for the first rotating member to rotate toward the second rotating position, so that the door leaf 200 is automatically switched to the closed state when no external force acts, thereby remaining closed.

In the present invention, the resistance set 20 is used to provide a buffering force, so that the door leaf 200 is buffered when rotating from the open state to the closed state, and the door closing speed is slowed down, thereby avoiding collision when the door leaf 200 is closed. In this embodiment, referring to fig. 18 to 21, the resistance set 20 includes a second housing 21, and a second rotating member and a buffer member 23 disposed on the second housing 21, where the second rotating member is mounted on the second housing 21 and is used to connect with the second end of the door leaf 200, so that the second rotating member has a third rotating position corresponding to the open state of the door leaf 200 and a fourth rotating position corresponding to the closed state of the door leaf 200. Specifically, the second rotating member is rotatably mounted to the second housing 21 about its own rotation axis, and the door leaf 200 is connected to the second rotating member such that the second rotating member rotates with the rotation of the door leaf 200. The damping member 23 is in driving connection with the second rotating member to provide a damping force in the course of the rotation of the second rotating member to the fourth rotational position. In this embodiment, the buffer member 23 may be a hydraulic damper, an oil pressure damper, an air cylinder, etc., and the transmission connection manner of the buffer member 23 and the second rotating member is not limited, for example, may be a link transmission, an abutting transmission, a rack-and-pinion engagement transmission, etc., so long as the buffer force provided by the buffer member 23 can be transmitted to the second rotating member through transmission, so as to drive the second rotating member to rotate, thereby slowing down the rotation speed of the door leaf 200. In this way, when the door leaf 200 rotates from the open state to the closed state, the second rotating member rotates correspondingly from the third rotating position to the fourth rotating position, and in this stroke, the damper 23 drivingly connected to the second rotating member provides a damping force, so that the closing speed of the door leaf 200 is slowed down.

In a preferred embodiment, referring to fig. 1 to 3, the power unit 10 is disposed on the upper frame 1001, the resistance unit 20 is disposed on the lower frame 1002, specifically, the rotation axes of the first rotation member and the second rotation member respectively extend in the up-down direction, that is, the first rotation member and the second rotation member are respectively rotatably disposed around the rotation axes extending in the up-down direction, the power unit 10 is disposed above the resistance unit 20, the first rotation member is used for being connected with the upper end of the door leaf 200 by a shaft, and the second rotation member is used for being connected with the lower end of the door leaf 200 by a shaft. In this embodiment, the power unit 10 is installed at the upper end of the door leaf 200, and the resistance unit 20 is installed at the lower end of the door leaf 200. In this manner, the drive member 13, e.g., elastic member, etc., in the power pack 10 is in a better environment and is less subject to moisture attack than the cushioning member 23, e.g., damper 231, etc., in the resistance pack 20. Because the buffer member 23 has better stability relative to the driving member 13, is less affected by the external environment (it will be appreciated that the elastic member is easily corroded, deforms or loses elasticity, and the sealed cylinder of the damper 231 has better durability), the arrangement can make the door closer assembly 100 have better overall durability, and the service life is prolonged, so that the door closer assembly can still provide a closing driving force and a buffer force meeting the requirements after long-term use.

On the basis of the above embodiment, as shown in fig. 4 and 5, a first connecting piece 14 is disposed below the first rotating piece, an upper end of the first connecting piece 14 is adjustably screwed to the first rotating piece in a vertical direction, a first clamping piece 15 is disposed at a lower end of the first connecting piece 14, and the first clamping piece 15 is used for clamping an upper end of the door leaf 200. In this way, the door leaf 200 is connected to the power unit 10 in an up-down adjustable manner by the cooperation of the first clamping member 15 and the first connecting member 14.

In yet another embodiment, a second connecting piece 24 is disposed above the second rotating piece, a lower end of the second connecting piece 24 is adjustably screwed to the second rotating piece in a vertical direction, and a second clamping piece 25 is disposed at an upper end of the second connecting piece 24, and the second clamping piece 25 is used for clamping a lower end of the door leaf 200. In this way, the door leaf 200 is connected to the resistance set 20 in an up-down adjustable manner by the cooperation of the second clamping member 25 and the second connecting member 24.

It will be appreciated that the two embodiments described above may be implemented separately or in combination.

In order to more firmly support the first rotating member, referring to fig. 6, in one embodiment, the first housing 11 is provided with two first bearings 16 disposed at intervals in the up-down direction, and two ends of the first rotating member are rotatably supported by the first bearings 16, respectively. The two ends of the first rotating member are thus rotatably supported by the first housing 11 via the first bearings 16, respectively, and are thus rotatably supported reliably and stably.

In yet another embodiment, the second housing 21 is provided with two second bearings 26 disposed at intervals in the up-down direction, and both ends of the second rotating member are rotatably supported by the respective second bearings 26. The second rotary member is thus rotatably supported at both ends thereof by the second housing 21 via the second bearings 26, respectively, so as to be rotatably supported reliably and stably.

In a preferred embodiment, referring to fig. 6 to 10, the first rotating member is a first cam 12, the driving member 13 includes a compression spring 131 extending in a transverse direction, and a first top member 132 disposed at one end of the compression spring 131, and the first top member 132 is movably disposed in the transverse direction on the first housing 11 and abuts against the first cam 12 under the action of the compression spring 131. The first cam 12 extends in the radial direction, and in the first rotational position, an end of the first cam 12 in a first direction abuts against the first top member 132, and in the second rotational position, an end of the first cam 12 in a second direction abuts against the first top member 132, and a diameter of the first cam 12 in the first direction is larger than a diameter thereof in the second direction. Referring to fig. 9, the first direction and the second direction are both radial to the first cam 12, and change orientation with rotation of the first cam 12. Specifically, the first direction extends generally in the lateral direction when the first cam 12 is in the first rotational position, and the second direction extends generally in the lateral direction when the first cam 12 is in the second rotational position. In this embodiment, the first cam 12 rotates with the rotation of the door leaf 200, and when the door leaf 200 rotates from the closed state to the open state, the first cam 12 rotates from the second rotational position to the first rotational position, and the compression spring 131 is compressed in the process, so that the compression spring 131 provides a restoring force for driving the first cam 12 to rotate, and drives the first cam 12 to rotate to the second rotational position. In this embodiment, the first direction and the second direction extend along the radial direction of the first cam 12, and are disposed to intersect, preferably perpendicularly, and in a preferred embodiment, the first cam 12 has a largest diameter in the first direction and a smallest diameter in the second direction.

In order to further reduce the size of the power pack 10 in the up-down direction, in one embodiment, a plurality of the compression springs 131 are provided, and a plurality of the compression springs 131 are arranged side by side in the width direction. And/or the driving members 13 are provided with two groups, and the two groups of driving members 13 are respectively arranged at two ends of the first cam 12 in the transverse direction. In this way, the compression spring 131 may have a smaller diameter, and the power pack 10 may be correspondingly lighter and thinner.

In order to guide the compression spring 131, referring to fig. 8, in one embodiment, a guide post 1320 is disposed at an end of the first top member 132 facing the compression spring 131, and the compression spring 131 is sleeved on the guide post 1320. In this way, in combination with the cavity shape of the first housing 11 for accommodating the compression spring 131, the compression direction of the compression spring 131 when being compressed can be limited, so as to avoid the compression spring 131 from being biased.

In another embodiment, referring to fig. 12 to 17, the first top member 132 includes a piston 1321 and a roller 1322 disposed in sequence in a lateral direction, the guide post 1320 is disposed on the piston 1321, a circular arc groove is formed on a side of the piston 1321 away from the guide post 1320, the roller 1322 is accommodated in the circular arc groove and is rotatably disposed, and the roller 1322 is configured to roll and abut against the first cam 12. In this way, the first top member 132 abuts against the first cam 12 in a rolling manner, so as to reduce the jamming condition in the rotation process of the door leaf 200, and improve the use experience.

Preferably, the first cam 12 is formed with a limit groove 120 at both sides in the second direction, respectively. As such, when the first cam 12 is at the second position, the roller 1322 is partially inserted into the limit groove 120, so that the door leaf 200 requires a larger external force to rotate toward the open state, thereby being more accurately maintained in the closed state.

In order to further enhance the use experience, arc-shaped chamfers 121 are respectively disposed at the adjacent positions of the two side walls of the first cam 12 in the first direction and the two side walls of the first cam 12 in the second direction. In this way, in the rotation process of the door leaf 200, the first cam 12 is always in smooth ground contact with the first top member 132, so that abrupt driving force changes are not easy to occur, and the rotation speed of the door leaf 200 is more smooth.

Optionally, the first top member 132 has a guide groove 1323 extending in a lateral direction, and the first housing 11 is provided with a boss 110 inserted into the guide groove 1323. In this way, the protrusion 110 cooperates with the guide groove 1323 to guide the movement of the first top 132 during the movement of the first top 132 in the lateral direction.

In yet another embodiment, the driving member 13 further includes a first adjusting member 17, where the first adjusting member 17 is disposed at an end of the compression spring 131 away from the first cam 12 and is adjustably disposed on the first housing 11 along a lateral position, and a first spacer 18 is disposed between the first adjusting member 17 and the compression spring 131. The first adjusting member 17 may be an adaptive screw or nut, and by adjusting the installation position of the pressure spring 131 on the first housing 11, the driving force provided by the pressure spring 131 is adjusted, and the first spacer 18 plays a role in dispersing the action of the first adjusting member 17 on the action of the action force of the pressure spring 131, so that the pressure spring 131 is stressed more uniformly and more stably.

In an embodiment, referring to fig. 18 to 22, the second rotating member is a second cam 22, the buffer member 23 includes a damper 231 with a damper rod moving along a lateral direction, and a second top member 232 disposed at one end of the damper rod, and the second top member 232 is movably disposed on the second housing 21 along the lateral direction and can abut against the second cam 22 under the action of the damper 231. The radial direction of the second cam 22 extends in the lateral direction, the end of the second cam 22 in the third direction abuts against the second top member 232 in the third rotational position, the end of the second cam 22 in the fourth direction abuts against the second top member 232 in the fourth rotational position, and the diameter of the second cam 22 in the fourth direction is larger than the diameter thereof in the third direction. Referring to fig. 20, the third direction and the fourth direction are both radial to the second cam 22, and change orientation with rotation of the second cam 22. Specifically, the third direction extends generally in the lateral direction when the second cam 22 is in the third rotational position, and the fourth direction extends generally in the lateral direction when the second cam 22 is in the fourth rotational position. In this embodiment, the second cam 22 rotates with the rotation of the door leaf 200, and when the door leaf 200 rotates from the open state to the closed state, the second cam 22 rotates from the third rotational position to the fourth rotational position, and the damper lever of the damper 231 is pressed in this process, so that the damper 231 provides a buffering force that prevents the rotation of the second cam 22, slowing down the closing speed of the door leaf 200. In this embodiment, the third direction and the fourth direction both extend along the radial direction of the second cam 22, and are disposed to intersect, preferably vertically, and in a preferred embodiment, the diameter of the second cam 22 in the fourth direction is the largest and the diameter in the third direction is the smallest.

In order to further reduce the size of the power pack 10 in the up-down direction, in one embodiment, the buffer member 23 includes a plurality of the dampers 231, and the plurality of dampers 231 are arranged side by side in the width direction. And/or, the buffer members 23 are provided with two groups, and the two groups of buffer members 23 are respectively arranged at two ends of the second cam 22 in the transverse direction. In this way, the damper 231 may have a smaller diameter, and the resistance set 20 may be correspondingly lighter and thinner in design.

In yet another embodiment, the buffer member 23 further includes a second adjusting member 27, where the second adjusting member 27 is disposed at an end of the damper 231 remote from the second cam 22 and is adjustably disposed on the second housing 21 along a lateral position, and a second spacer 28 is disposed between the second adjusting member 27 and the damper 231. The second adjusting member 27 may be an adapted screw or nut, and by adjusting the mounting position of the damper 231 on the second housing 21, thereby adjusting the buffering stroke provided by the damper 231, the second spacer 28 acts to disperse the force of the second adjusting member 27 on the damper 231, so that the damper 231 is stressed more uniformly and stably.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
