[0056] The technical solutions of the utility model will be further described below in combination with the specific embodiments. Figures 1-10 The technical solutions of the utility model will be further described below in combination with the specific embodiments.

[0057] Please refer to Figure 1 The utility model embodiment provides a slide rail type functional desktop armrest sofa, which comprises a seat body 1, an armrest 2 and a table plate assembly 3.

[0058] The seat body 1 is in the structure of a multi-person seat sofa, has a horizontal length direction, and at the same time, a guide rail assembly 4 is arranged between the seat body 1 and the armrest 2, and the armrest 2 is arranged to slide along the length direction of the seat body 1 through the guide rail assembly 4. At this time, the position of the armrest 2 is adjusted, so that the form of the sofa can be changed, for example, the armrest 2 is pushed to one side of the seat body 1, at this time, the sofa forms a concubine chair, which is suitable for side lying or side lying. In addition, the armrest 2 is pushed to the middle of the seat body 1, so that a double seat sofa can be formed, and the use flexibility of the sofa is greatly improved.

[0059] On this basis, the table plate assembly 3 is movably arranged on the top of the armrest 2, and the table plate assembly 3 can be opened or folded compared with the armrest 2. When the table plate assembly 3 is opened compared with the armrest 2, a table top structure can be formed, so that articles can be placed on the armrest 2, writing or dining affairs can be carried out and the like.

[0060] By adopting the above scheme, on one hand, the sofa can form different use modes by adjusting the relative position of the armrest 2; and under the action of the table plate assembly 3, the armrest 2 can be endowed with a desktop function, in combination with the armrest 2 capable of displacement adjustment, a movable table plate structure is formed, the value of the armrest 2 part of the sofa can be maximized, and the use experience of different users in multiple scenes can be met.

[0061] Further, referring to Figure 2 and Figure 3 In order to enable the armrest 2 to stably slide and adjust on the seat body 1, the guide rail assembly 4 in the embodiment comprises a track module 41 and a sliding block 42.

[0062] The track module 41 adopts a high-strength aluminum alloy damping sliding rail and is fixed at the bottom of the seat body 1; at the same time, the main frame of the armrest 2 in the embodiment is in an inverted L-shaped structure, and the outer layer of the main frame is wrapped with a sponge and a leather cover to improve the comfort of the armrest 2. In addition, the armrest 2 has a concave avoiding contour, and the armrest 2 is embedded with the seat body 1 through the concave contour, so that the structure is more compact. At this time, the sliding block 42 is fixedly arranged at the bottom of the armrest 2, and the sliding block 42 is in sliding cooperation with the track module 41. Under the cooperation of the sliding block 42 and the track module 41, the armrest 2 can smoothly slide along the length direction of the seat body 1, and the use experience is improved.

[0063] Further, referring to Figure 4 In one of the implementation manners provided in the embodiment, the table plate assembly 3 comprises a lower table plate 32 and an upper table plate 31.

[0064] The lower table plate 32 is horizontally arranged and fixedly arranged at the top of the armrest 2; one side of the upper table plate 31 is rotationally arranged at one side of the lower table plate 32; based on the above arrangement, the upper table plate 31 can be rotationally overlapped above the lower table plate 32, so that the upper table plate 31 can be folded compared with the lower table plate 32. At this time, the table plate assembly 3 is in a folded state; and the upper table plate 31 can also be rotationally opened from the folded state to one side, so that the upper table plate 31 is horizontally rotationally opened to the adjacent side of the lower table plate 32. At this time, the table plate assembly 3 is in an opened state.

[0065] When the table surface is needed to be used, the upper table plate 31 can be opened, and the upper table plate 31 and the lower table plate 32 are both horizontally arranged, so that the upper table plate 31 and the lower table plate 32 form a table surface structure; when the table surface is not needed to be used, the upper table plate 31 can be rotated and folded, so that the armrest 2 is formed at this time. The structure is convenient and flexible to use.

[0066] Optionally, in order to improve the comfort of the table board in the handrail 2 state, the upper table board 31 is provided with a soft layer 311 on the side away from the lower table board 32 in the folded state. It can be understood that the soft layer 311 is mainly composed of sponge and leather layers. By providing the soft layer 311 on the upper table board 31, the use comfort of the handrail 2 can be improved.

[0067] With reference to the above description Figure 4 In order to further expand the overall area of the table top and to further make full use of the structural space, the table board assembly 3 in the embodiment further comprises a middle table board 33.

[0068] The upper table board 31 and the middle table board 33 are respectively rotatably arranged on opposite sides of the lower table board 32. At this time, the upper table board 31 and the middle table board 33 can be respectively opened towards opposite sides of the lower table board 32, thereby improving the overall area of the table top, and both can also be folded on the lower table board 32 at the same time. Specifically, when both are folded, the upper table board 31 is located above the middle table board 33.

[0069] Based on the above structure, there are four modes between the upper table board 31 and the middle table board 33. In the first mode, the upper table board 31 and the middle table board 33 are simultaneously stacked above the lower table board 32, and the upper table board 31 is located above the middle table board 33. In the second state, the upper table board 31 is opened by rotating to one side, and the middle table board 33 is folded on the lower table board 32. In the third state, the upper table board 31 is folded above the lower table board 32, and the middle table board 33 is opened by rotating to one side of the lower table board 32. In the fourth state, the upper table board 31 and the middle table board 33 are respectively opened by rotating to opposite sides of the lower table board 32.

[0070] As described above, the above four states can be summarized into two mode types, namely:

[0071] When the table board assembly 3 is in the open state, the upper table board 31 and / or the middle table board 33 are opened by rotating compared to the lower table board 32. At this time, the second, third and fourth states are included. At this time, the table board assembly 3 can function as a table top.

[0072] When the table board assembly 3 is in the folded state, the middle table board 33 is folded on the upper side of the lower table board 32, and the upper table board 31 is folded on the upper side of the middle table board 33, i.e. the first state described above. At this time, the table board assembly 3 does not provide a table top function.

[0073] By adopting the above embodiment, the opening orientation and opening mode of the table board assembly 3 can be adjusted according to actual needs. The structure is variable and flexible to use, and can meet the diverse use needs of different customers.

[0074] It can be understood that, with reference to the above description Figure 5 and Figure 6In one of the common embodiments, the middle table plate 33 is rotatably installed on one side of the lower table plate 32 through a damping hinge 12. In order to realize the stacking of the upper table plate 31 above the middle table plate 33, a boss is arranged on the other side of the lower table plate 32, and then the upper table plate 31 is rotatably connected to the boss through another damping hinge 12, so as to elevate the upper table plate 31. In this way, the vertical space requirement when the upper table plate 31 and the middle table plate 33 are folded at the same time can be met, and the upper table plate 31 and the middle table plate 33 can be folded at the same time.

[0075] However, the above arrangement causes the upper table plate 31 and the middle table plate 33 to have different heights when they are opened at the same time, which makes it difficult to form a whole plane and affects the functional use of the table top. Therefore, the guide hinge 5 is arranged between the upper table plate 31 and the lower table plate 32 in the embodiment.

[0076] Referring to Figure 7 and Figure 8 , the guide hinge 5 includes a guide piece 51, a first hinge piece 52 and a second hinge piece 53. The guide piece 51 includes two waist-shaped rings 511 and a connecting sheet 512. The two waist-shaped rings 511 are parallel to each other and are fixedly arranged on opposite sides of the connecting sheet 512. A strip-shaped sliding groove is formed in the upper waist-shaped ring 511 of the guide piece 51, and the strip-shaped sliding groove extends from one side to the other side of the width direction of the guide piece 51. At the same time, the first hinge piece 52 includes a sheet part and a shaft body arranged on one side of the sheet part. The second hinge piece 53 has the same structure as the first hinge piece 52, and details are not repeated here.

[0077] At this time, the first hinge piece 52 is fixedly arranged on the upper table plate 31. Generally, the sheet part of the first hinge piece 52 can be fixed on the upper table plate 31 by screwing. The specific installation method is not limited here. The shaft body of the first hinge piece 52 is rotatably arranged in the strip-shaped sliding groove and is slidingly arranged along the length direction of the strip-shaped sliding groove. Specifically, the opening width of the strip-shaped sliding groove is matched with the diameter of the shaft body. The two ends of the shaft body of the first hinge piece 52 are inserted into the strip-shaped sliding grooves of the two waist-shaped rings 511, so that the shaft body can rotate in the strip-shaped sliding groove. Since the strip-shaped sliding groove has a long displacement space, the shaft body can also have a degree of freedom of movement along the strip-shaped sliding groove during rotation.

[0078] Correspondingly, the second hinge piece 53 is fixedly arranged on the lower table plate 32. The shaft body of the second hinge piece 53 is rotatably arranged in the strip-shaped sliding groove and is slidingly arranged along the length direction of the strip-shaped sliding groove. The specific installation method of the second hinge piece 53 is similar to that of the first hinge piece 52, and details are not repeated here.

[0079] By adopting the above scheme, the upper table plate 31 can obtain the movement freedom degree of rotation and sliding relative to the guide rail 51 through the first hinge 52, and the lower table plate 32 can obtain the movement freedom degree of rotation and sliding relative to the guide rail 51 through the second hinge 53; when the upper table plate 31 and the middle table plate 33 are stacked at the same time, the rotation shaft of the second hinge 53 and the rotation shaft of the first hinge 52 can be pulled to the two ends of the strip-shaped sliding groove, so as to form a gap between the upper table plate 31 and the lower table plate 32 in the vertical direction, and the gap can accommodate the middle table plate 33, thereby realizing the stacking function; when the upper table plate 31 and the middle table plate 33 are opened at the same time, because the guide rail 51 provides a large movement freedom degree, the guide rail 51 can be laid flat, and then the surface of the upper table plate 31 and the surface of the lower table plate 32 are flush on the same horizontal plane, so that the flat table surface of the upper table plate 31, the middle table plate 33 and the lower table plate 32 is obtained, and the use experience of the user is optimized and improved.

[0080] Further, with reference to Figure 8 and Figure 9 In order to eliminate the gap between the upper table plate 31 and the lower table plate 32 when the upper table plate 31 is opened, the embodiment is provided with a positioning slot 6 at the lower table plate 32 or the upper table plate 31.

[0081] Specifically, the positioning slot 6 is opened at one side edge of the upper table plate 31 or the lower table plate 32, and at this time, when the guide rail 51 is laid flat, the guide rail 51 can be inserted into the positioning slot 6 by pushing the upper table plate 31 to approach the lower table plate 32, so as to realize the horizontal insertion and positioning effect, and thus the gap between the upper table plate 31 and the lower table plate 32 can be well eliminated, and the whole table surface is more compact.

[0082] In another embodiment, the positioning slot 6 can also be provided at the side edge of the upper table plate 31 and the lower table plate 32 respectively, so that the function of eliminating the gap of the table surface can also be realized, and the specific layout of the positioning slot 6 is not limited herein.

[0083] Optionally, in order to avoid the shift and sliding of the handrail 2 when it is stopped, a self-locking device 7 (not shown in the figure) can be arranged between the seat body 1 and the handrail 2. In one embodiment, a magnetic positioning method can be adopted, for example, an electromagnet module is arranged at the seat body 1 and the handrail 2 respectively, and the handrail 2 is stopped by connecting the control system 9 and the power supply and using the magnetic attraction force of the two.

[0084] In the present embodiment, the specific structure of the self-locking device 7 is not limited, as long as the technical solution of the position stop of the handrail 2 is achieved, it should be included in the interpretation range of the self-locking device 7.

[0085] In addition, regarding the position adjustment mode of the handrail 2, in one embodiment, the handrail 2 can be adjusted by manual pushing and pulling, which facilitates the separate packaging, transportation and assembly of each component, and also realizes modular production, simplifies the manufacturing process, reduces the cost, and improves the product compatibility and maintainability.

[0086] In another embodiment, the handrail 2 can also be adjusted by an electric adjustment mode to improve the convenience in the operation process. Specifically, referring to Figure 10 , the handrail 2 and the seat body 1 are provided with an electric module 8 (not shown in the figure), and the electric module 8 is connected with a control system 9 for controlling the start and stop of the electric module 8, and the electric module 8 is used to drive the displacement adjustment of the handrail 2 relative to the seat body 1.

[0087] It can be understood that the electric module 8 can be a linear module or a motor module that can output linear reciprocating motion. Taking the motor module as an example, the motor module generally includes a driving motor, a gear and a rack. The rack is fixedly arranged at the bottom of the seat body 1, the driving motor is arranged on the handrail 2, the gear is fixed on the output shaft of the driving motor, and the gear is engaged with the rack. At this time, by controlling the start of the driving motor, the gear can be driven to rotate, and under the engagement, the handrail 2 can be finally pushed to displace, so as to realize the electric adjustment function of the handrail 2. Here, the specific structure of the electric module 8 is not limited, as long as the module structure that can realize the electric adjustment function can be used, which is not limited here.

[0088] In addition, the control system 9 is generally composed of a PCB and a main control chip. The main control chip is arranged on the PCB. By electrically connecting the control system 9 and the electric module 8, the start and stop control function can be realized under the control interaction of the main control chip. In addition, a Bluetooth module can be arranged on the PCB of the control system 9, and a remote controller can be arranged. The remote control function can be realized through the communication connection between the remote controller and the Bluetooth module. Further, a memory module can be added to the control system 9. The moving track of the handrail 2 and the coordinate value of the commonly used stop position are recorded by the memory module. Combined with the remote controller, the one-key reset function can be realized.

[0089] Further, continuing to refer to Figure 10 In actual use, the user may accidentally touch the remote controller, which may cause unnecessary movement of the handrail 2. To prevent the above situation, the present embodiment further includes a sensor 10 and a self-locking device 7.

[0090] The sensor 10 can be an infrared sensor 10 or a pressure sensor 10, and is installed on the seat body 1 and electrically connected with the control system 9. The self-locking device 7 is arranged between the seat body 1 and the armrest 2, and the specific structure is not described here. At the same time, the control system 9 is connected with the sensor 10 and the self-locking device 7, and the sensor 10 is used to detect the use state of the user.

[0091] When the user sits on the seat body 1, the sensor 10 is triggered to generate a high-level signal, which is sent to the control system 9. At this time, the control chip can determine that the sofa is in a use state, and the control system 9 generates a control signal based on the state and sends it to the self-locking device 7 to control it to start, thereby locking the armrest 2. When the user leaves the seat body 1, the sensor 10 is not triggered, and a low-level signal is generated. At this time, the sofa is in a non-use state, and the self-locking device 7 is not started, thereby enabling remote control of the position of the armrest 2.

[0092] Based on the above sensing mode, the control system 9 can control the self-locking device 7 to start and stop based on the use state of the user, avoid unnecessary displacement of the armrest 2, and further optimize the user experience.

[0093] Further, some users have charging needs when using the sofa, so the charging module 11 is also included. The charging module 11 can be a USB charging port, a wireless charger, or the like. According to different use needs, the charging module 11 can be arranged on the armrest 2, the seat body 1, or the table plate assembly 3. The specific arrangement of the charging module 11 is not limited here. In this embodiment, the charging module 11 is a wireless charger and is installed on the table plate assembly 3. The charging module 11 is electrically connected with the control system 9, and is powered by the power supply module on the control system 9.

[0094] The embodiments of the present application have the following advantages:

[0095] 1. By arranging the guide rail assembly 4, the armrest 2 can freely move and stop at any position of the sofa, increasing the actual use scene and enhancing the multifunctionality of the armrest 2.
