Description

Technical Field

[0001] This utility model relates to the field of automated home furnishing, and more specifically, to an installation component and a seat structure. Background Technology

[0002] In related technologies, by setting a flip-up movable plate on the seat structure such as electric sofas or electric seats, the movable plate can be unfolded when needed and stored away when not in use. While providing support, it can also reduce the space occupied when not in use, greatly improving the user experience.

[0003] For the aforementioned seat structure, anti-pinch detection during the flipping and storage process of the movable panel is very important. By implementing anti-pinch detection, it is possible to prevent the movable panel from pinching the limbs of a person or small animal that accidentally moves into its movement path.

[0004] Specifically, the aforementioned anti-pinch detection can be achieved through a detection component installed on the seat structure. This component detects whether there is an object between itself and the movable plate. Once an object is detected, a warning can be issued or the movement of the movable plate can be stopped directly. Since the movable plate is a moving part, ensuring that it remains within the detection range of the detection component throughout its movement is a crucial issue that needs to be addressed during the installation of the detection component. Utility Model Content

[0005] The main objective of this invention is to provide a mounting assembly and seat structure for a seat structure, in order to solve the problem in related technologies of how to ensure that the movable plate is always within the detection range of the detection assembly during its movement.

[0006] To achieve the above objectives, according to one aspect of the present invention, a mounting assembly for a seat structure is provided, wherein the seat structure includes a seat frame and a detection assembly, the mounting assembly being used to mount the detection assembly on the seat frame, and the mounting assembly including: a mounting rod; a connecting side plate disposed at the end of the mounting rod, the connecting side plate being used to connect to the seat frame; and a mounting bracket connected to the mounting rod, the mounting bracket having an inclined mounting surface, on which the detection assembly is mounted.

[0007] Furthermore, the mounting frame includes a first frame fixedly mounted on a mounting rod and a second frame movably connected to the first frame. An inclined mounting surface is formed on the second frame, and the second frame can change the inclination angle of the inclined mounting surface relative to the vertical direction when it moves relative to the first frame.

[0010] Furthermore, the mounting bracket also includes a bushing fitted onto the pin. The bushing includes a sleeve and an end plate. The end plate is located between the second connecting plate and the fourth connecting plate, and the sleeve is located between the pin and the fourth connecting plate.

[0011] Furthermore, the mounting bracket also includes a locking rod. One of the first and second frames is provided with a plurality of first adjustment holes arranged along a preset arc, the center of the preset arc coinciding with the axis of the pin. The other of the first and second frames is provided with a second adjustment hole. The locking rod passes through the second adjustment hole and a first adjustment hole to fix the first and second frames.

[0012] Furthermore, the connecting side plate is adjustablely mounted on the seat frame in the vertical and / or front-to-back direction.

[0013] Furthermore, the connecting side plate is arrayed with multiple connecting holes, wherein the number of connecting holes in the front-to-back direction is greater than or equal to 2; and / or, the number of connecting holes in the up-down direction is greater than or equal to 2.

[0015] Furthermore, the seat structure also includes a seat frame, a drive unit, a movable plate, and a detection component. The detection component is mounted on the seat frame via a mounting component. The drive unit connects the movable plate and the seat frame. The drive unit drives the movable plate to flip so that the movable plate switches between a retracted position close to the detection component and an unfolded position away from the detection component. When the movable plate switches between the retracted and unfolded positions, the lower edge of the movable plate is always within the detection range of the detection component.

[0016] Furthermore, the seat structure also includes a seat frame, a drive unit, a movable plate, and a detection assembly.

When the movable plate is in the retracted position, the lower detection surface is flush with or lower than the lower edge of the movable plate; and / or, the angle α between the inclined mounting surface and the vertical direction satisfies: α = arcsin(tanM / 2), where M is the detection angle of the detection assembly.

[0017] Furthermore, the seat frame includes a left fixed side plate, a right fixed side plate, and a mechanical extension device spaced apart, with the drive unit, movable plate, and detection assembly all disposed between the left fixed side plate and the right fixed side plate.

The detection component is mounted on the inclined mounting surface, which allows the front surface of the detection component to also be inclined, thereby adapting the detection range of the detection component to the movement range of the movable plate, ensuring that the movable plate can always be detected by the detection component during its movement. Therefore, the technical solution of this application effectively solves the problem in related technologies of how to ensure that the movable plate remains within the detection range of the detection component during its movement.

[0041] like Figures 1 to 7 As shown, this application provides a mounting assembly for a seat structure, wherein, Figures 1 to 2 A schematic diagram of the structure of a first embodiment of the mounting component according to this application is shown; Figures 3 to 7 A schematic diagram of a second embodiment of the mounting component according to this application is shown.

[0042] like Figure 8 and Figure 9 As shown, the seat structure includes a seat frame 1 and a detection component 2. The mounting component is used to mount the detection component 2 on the seat frame 1 so that the detection component 2 can detect whether a foreign object is inserted during the retraction of the movable plate 4.

[0043] like Figure 1 and Figure 2 As shown, the first embodiment of the mounting assembly of this application includes: a mounting rod 10, a connecting side plate 20, and a mounting bracket 30. The connecting side plate 20 is disposed at the end of the mounting rod 10 and is used to connect to the seat frame 1; the mounting bracket 30 is connected to the mounting rod 10 and has an inclined mounting surface 301 on which the detection assembly 2 is mounted.

[0044] Applying the technical solution of this embodiment, the connecting side plate 20 is disposed at one end of the mounting rod 10 and can be connected to the seat frame 1 to install the mounting assembly on the seat frame 1 of the seat structure; the mounting bracket 30 is connected to the mounting rod 10 and has an inclined mounting surface 301 for mounting the detection assembly 2, enabling the detection assembly 2 to be mounted on the seat frame 1 via the mounting bracket 30. The detection assembly 2 is mounted on the inclined mounting surface 301, which allows the front surface of the detection assembly 2 (the front surface of the detection assembly 2 has a detector capable of emitting and receiving light pulses) to also be inclined, thereby adapting the detection range of the detection assembly 2 to the movement range of the movable plate 4, ensuring that the movable plate 4 can always be detected by the detection assembly 2 during its movement. Therefore, the technical solution of this embodiment can effectively solve the problem in related technologies of how to ensure that the movable plate is always within the detection range of the detection assembly during its movement.

[0045] like Figure 1 and Figure 2 As shown, the mounting assembly includes two connecting side plates 20, which are respectively disposed at both ends of the mounting rod 10 to ensure that the mounting assembly can be stably and securely installed on the seat frame 1. The mounting rod 10 is a hollow rod-shaped structure with a square cross-section. The connecting side plates 20 are provided with connecting holes 22. When connecting the mounting assembly to the seat frame 1, fasteners passing through the connecting holes 22 and the seat frame 1 can be used to fix the mounting assembly to the seat frame 1.

[0046] Of course, in embodiments not shown in the figure, the mounting rod can also be a hollow rod structure with other cross-sectional shapes (e.g., rectangular, hexagonal, etc.) or a profile structure, and the connecting side plate can also be connected to the seat frame by means of a snap-fit ​​structure or other connection methods.

[0047] like Figure 1 and Figure 2 As shown, the mounting bracket 30 includes a mounting plate and a mounting ramp connected to the lower end of the mounting plate. The mounting plate is used to connect with the mounting rod 10. An inclined mounting surface 301 is formed on the mounting ramp. The detection component 2 can be mounted on the inclined mounting surface 301 by fasteners or a snap-fit ​​structure.

[0048] Specifically, in this embodiment, the inclined mounting surface 301 faces obliquely upwards on the side where the movable plate 4 is located, thereby making the detection range of the detection component 2 installed on the inclined mounting surface 301 compatible with the movement range of the movable plate 4.

[0049] Figures 3 to 7 A schematic diagram of the structure of the second embodiment of the mounting component according to this application is shown. The following mainly describes the parts of the second embodiment that are different from the first embodiment. The parts that are the same in the two embodiments will not be described again.

[0050] like Figures 3 to 5 As shown, in this embodiment, the mounting assembly also includes a mounting rod 10, a connecting side plate 20, and a mounting frame 30. The mounting frame 30 includes a first frame 31 fixedly mounted on the mounting rod 10 and a second frame 32 movably connected to the first frame 31. An inclined mounting surface 301 is formed on the second frame 32. When the second frame 32 moves relative to the first frame 31, it can change the tilt angle of the inclined mounting surface 301 relative to the vertical direction. By setting the mounting frame 30 as a split structure, the operator can change the tilt angle of the inclined mounting surface 301 relative to the vertical direction by adjusting the position and / or posture of the second frame 32 relative to the first frame 31. This improves the versatility of the mounting assembly, enabling it to be used to install detection components 2 for different types and specifications of seat structures, avoiding the need to equip different types or specifications of seat structures with mounting assemblies having inclined mounting surfaces with different tilt angles.

[0051] like Figures 5 to 7 As shown, the mounting bracket 30 also includes a pin 33, which passes through the first frame 31 and the second frame 32, so that the second frame 32 is rotatably mounted relative to the first frame 31. By having both the first frame 31 and the second frame 32 pass through the pin 33, the posture of the second frame 32 relative to the first frame 31 can be adjusted, thereby adjusting the tilt angle of the inclined mounting surface 301. This design has the advantages of simple structure and easy adjustment.

[0052] like Figures 5 to 7 As shown, the first frame 31 includes a first connecting plate 311 and a second connecting plate 312 arranged at an angle to the first connecting plate 311. The first connecting plate 311 is connected to the mounting rod 10. Specifically, the first frame 31 includes two second connecting plates 312, which are respectively connected to the left and right ends of the first connecting plate 311 and are perpendicular to the first connecting plate 311.

[0053] like Figures 5 to 7As shown, the second frame 32 includes a third connecting plate 321 and a fourth connecting plate 322 angled to the third connecting plate 321. An inclined mounting surface 301 is formed on the third connecting plate 321. The fourth connecting plate 322 and the second connecting plate 312 are stacked, and a pin 33 passes through the fourth connecting plate 322 and the second connecting plate 312. Specifically, the second frame 32 includes two fourth connecting plates 322, which are respectively connected to the left and right sides of the third connecting plate 321 and perpendicular to the third connecting plate 321. The two fourth connecting plates 322 are located inside the two second connecting plates 312. Both the second connecting plate 312 and the fourth connecting plate 322 have through holes, and the pin 33 passes through the through holes of the two second connecting plates 312 and the two fourth connecting plates 322, so that the second frame 32 is rotatably mounted relative to the first frame 31.

[0054] Specifically, such as Figure 7 As shown, the pin 33 is a screw structure, which includes a rod body, a screw head at one end of the rod body, and a nut at the other end of the rod body. The screw head and the nut respectively cooperate with the outer end faces of the two second connecting plates 312.

[0055] like Figure 6 and Figure 7 As shown, the mounting bracket 30 also includes a bushing 34 sleeved on the pin 33. The bushing 34 includes a sleeve 341 and an end plate 342. The end plate 342 is located between the second connecting plate 312 and the fourth connecting plate 322, and the sleeve 341 is located between the pin 33 and the fourth connecting plate 322. The end plate 342, located between the second connecting plate 312 and the fourth connecting plate 322, can separate the second connecting plate 312 and the fourth connecting plate 322 and play a role in reducing friction. The sleeve 341 is located between the outer wall surface of the pin 33 and the inner wall surface of the through hole of the fourth connecting plate 322. The sleeve 341 can separate the pin 33 and the fourth connecting plate 322 and play a role in reducing friction. The bushing 34 can improve the smoothness of the rotation of the second frame 32 relative to the first frame 31, and at the same time reduce the wear of the first frame 31 and the second frame 32 during the adjustment process.

[0056] like Figure 5 and Figure 7As shown, the mounting bracket 30 also includes a locking rod 35. One of the first bracket 31 and the second bracket 32 ​​is provided with a plurality of first adjustment holes 361 arranged along a preset arc. The center of the preset arc coincides with the axis of the pin 33. The other of the first bracket 31 and the second bracket 32 ​​is provided with a second adjustment hole 362. The locking rod 35 passes through the second adjustment hole 362 and one of the first adjustment holes 361 to fix the first bracket 31 and the second bracket 32. Specifically, the plurality of first adjustment holes 361 are provided on the second connecting plate 312, and the number of second adjustment holes 362 is one and is provided on the fourth connecting plate 322. By making the second adjustment hole 362 correspond to different first adjustment holes 361 and by making the locking rod 35 pass through the second adjustment hole 362 and the corresponding first adjustment hole 361, the second bracket 32 ​​can be fixed on the first bracket 31, which has the advantages of simple structure and easy adjustment.

[0057] Specifically, in this embodiment, the locking rod 35 is a screw structure, and the inner wall surface of the first adjusting hole 361 and / or the second adjusting hole 362 is provided with an internal thread that mates with the external thread of the screw structure. There are two locking rods 35, which lock the two sets of second connecting plates 312 and fourth connecting plates 322 respectively.

[0058] Specifically, this application does not limit the materials of the first frame 31 and the second frame 32. The first frame 31 and the second frame 32 can be made of metal, plastic or other materials.

[0059] like Figure 3 and Figure 4 As shown, the connecting side plate 20 is adjustablely mounted on the seat frame 1 in both the vertical and horizontal directions. This configuration allows for adjustment of the mounting component's position on the seat frame 1 in both the vertical and horizontal directions, thereby improving the versatility of the mounting component. This enables the mounting component to be used to install detection components 2 for different types and specifications of seat structures, avoiding the need to equip different sized mounting components for different types or specifications of seat structures.

[0060] In this embodiment, the position of the connecting side plate 20 is adjustable in both the vertical and horizontal directions. In an embodiment not shown in the figure, the connecting side plate can be configured to be adjustable only in the vertical direction or only in the horizontal direction.

[0061] like Figure 3 and Figure 4As shown, the connecting side plate 20 is provided with a plurality of connecting holes 21 arranged in an array. The number of connecting holes 21 in the front-to-back direction is greater than or equal to 2, and the number of connecting holes 21 in the vertical direction is greater than or equal to 2. Specifically, the connection with the seat frame 1 can be achieved through different connecting holes 21 in the front-to-back direction and different connecting holes 21 in the vertical direction, thereby realizing the adjustment of the position of the mounting component in the front-to-back direction and the vertical direction.

[0062] Specifically, in this embodiment, the mounting component can be fixedly connected to the seat frame 1 by fasteners passing through the connection hole 21 and the seat frame 1.

[0063] In this embodiment, the connecting side plate 20 is a rectangular plate. Of course, the shape and size of the connecting side plate are not limited to the shape and size shown in the accompanying drawings of this embodiment, as long as the front-to-back position and the up-to-down position of the mounting components can be adjusted.

[0064] like Figures 8 to 12 As shown, this application also provides a seat structure. The seat structure of this embodiment includes a mounting assembly, wherein the mounting assembly is the aforementioned mounting assembly. The aforementioned mounting assembly can effectively solve the problem in the related art of how to ensure that the movable plate is always within the detection range of the detection assembly during its movement. The seat structure with the aforementioned mounting assembly also has the aforementioned advantages.

[0065] like Figures 10 to 12 As shown, the seat structure also includes a seat frame 1, a drive unit 3, a movable plate 4, and a detection component 2. The detection component 2 is mounted on the seat frame 1 via a mounting assembly. The drive unit 3 connects the movable plate 4 and the seat frame 1. The drive unit 3 drives the movable plate 4 to rotate, allowing it to switch between a retracted position close to the detection component 2 and an unfolded position away from the detection component 2. When the movable plate 4 switches between the retracted and unfolded positions, its lower edge remains within the detection range of the detection component 2. Specifically, the movable plate 4 can rotate relative to the seat frame 1 under the drive of the drive unit 3 and can switch between the unfolded and retracted positions. Since its lower edge remains within the detection range of the detection component 2 during this switching process, the movable plate 4 can always be detected by the detection component 2, thus ensuring effective detection of foreign objects on the movable plate 4 and the detection component 2. Specifically, in this embodiment, the seat structure is an electric sofa, and the movable plate 4 is a movable leg rest. The movable leg rest can switch between an unfolded position and a folded position to increase the user's flexibility and comfort.

[0066] Specifically, in this embodiment, the seat structure is an electric sofa, and its seat frame 1 is constructed as a floor-standing armrest seat frame. During use, it is fixed in position relative to the ground. For example, the seat frame 1 includes a left fixed side plate and a right fixed side plate spaced apart, wherein the left fixed side plate and the right fixed side plate constitute a fixed unit. The driving component, the movable plate, and the detection component are all disposed between the left fixed side plate and the right fixed side plate. The driving component 3 includes a driver 3a and a mechanical extension device 3b, and the mechanical extension device 3b constitutes a movable unit. The mechanical extension device is disposed between the spaced left fixed side plate and the right fixed side plate. The driver 3a can drive the mechanical extension device to unfold and retract. The movable plate can be fixed to the mechanical extension device and switched between the retracted position and the unfolded position by the mechanical extension device. Therefore, the mounting component can be installed between the left fixed side plate and the right fixed side plate. Specifically, it can be fixed to the left fixed side plate and the right fixed side plate to be directly installed on the seat frame 1, or it can be fixed to the mechanical extension device 3b to be indirectly installed on the seat frame 1.

[0067] Of course, in embodiments not shown in the figures, the seat structure can also be an electric seat, an electric sofa bed, a car seat, etc. The seat frame can also be any of the fixing units included in any of the seat structures described above. Furthermore, the form of the fixing unit is not limited to the combination of the left and right fixing side plates described above; for example, the fixing unit can be a fixing seat.

[0068] like Figures 10 to 12 As shown, the seat structure also includes a seat frame 1, a drive unit 3, a movable plate 4, and a detection component 2. The detection component 2 is mounted on the seat frame 1 via a mounting assembly. The drive unit 3 is connected between the movable plate 4 and the seat frame 1. The drive unit 3 drives the movable plate 4 to rotate so that the movable plate 4 switches between a retracted position close to the detection component 2 and an unfolded position away from the detection component 2. When the movable plate 4 is in the retracted position, the movable plate 4 extends vertically. The detection component 2 has a detection range facing the movable plate 4, which is enclosed by a lower detection surface F1, an upper detection surface F2, a left detection surface F3, and a right detection surface F4. When the movable plate 4 is in the retracted position, the lower detection surface is flush with or lower than the lower edge of the movable plate 4. And / or, the angle α between the inclined mounting surface 301 and the vertical direction satisfies: α = arcsin(tanM / 2), where M is the detection angle of the detection component 2.

[0069] Specifically, the detection component 2 is a D-TOF (Direct Time of Flight) sensor. How the detection component 2 detects foreign objects located between itself and the movable plate 4 has been disclosed in Chinese Patent Application No. 202411325792.X. In this application, the movable plate 4 is within the detection range of the detection component 2, and the detection range of the detection component 2 is as follows: Figures 10 to 12As shown, the detection range is enclosed by the lower detection surface F1, the upper detection surface F2, the left detection surface F3, and the right detection surface F4. The lower detection surface F1, the upper detection surface F2, the left detection surface F3, and the right detection surface F4 gradually expand outward in the direction away from the detection component 2, forming a four-sided pyramid-shaped detection space.

[0070] Among them, the lower detection surface F1, the upper detection surface F2, the left detection surface F3 and the right detection surface F4 are all the same triangle, and they all have equal apex angles in the direction close to the detection component 2. The apex angle is the detection angle M of the detection component 2.

[0071] When installing the mounting components and the detection components 2, the lower detection surface is made flush with or lower than the lower edge of the movable plate 4 when it is in the retracted position (at which time the lower edge of the movable plate 4 is at its lowest position during its movement). This ensures that the lower edge of the movable plate 4 is within the detection range of the detection components 2 when it is in the retracted position, and also ensures that the lower edge of the movable plate 4 is always within the detection range of the detection components 2 during its movement.

[0072] By ensuring that the angle α between the inclined mounting surface 301 and the vertical direction satisfies: α = arcsin(tanM / 2), it can be guaranteed that the lower detection surface F1 of the detection component 2 is nearly parallel to the ground. Combined with the installation height of the mounting component, the lower edge of the movable plate 4 in the storage position is located above the lower detection surface F1 and is at a small distance from or flush with the lower detection surface F1. This achieves the detection of the movable plate 4 while avoiding the detection of other structures in front of the movable plate 4, which would affect the accuracy of the detection.

[0073] In addition, when installing the mounting components and the detection components 2, it is also necessary to consider the position of the mounting components in the front-back direction. It is necessary to ensure that the leg rest is within the detection range of the detection components 2, but the side panels of the seat frame 1 (i.e., the left fixed side panel and the right fixed side panel) are outside the detection range of the detection components 2, so as to avoid affecting the accuracy of the detection.

[0074] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0075] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0076] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0077] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
