Description

Technical Field

[0001] This invention relates to the field of smart home technology, and in particular to a mattress limiting device. Background Technology

[0002] Current smart beds generally use segmented movable bed boards, which can be raised and folded individually for areas such as the head, waist, and legs, effectively improving the user's lying experience and the product's practicality. However, during posture adjustment, the mattress is prone to shifting, slipping, or localized arching due to gravity, tilt angle, and human body forces. To address this issue, the industry typically adds fixing strips or panels as limiting components at the headboard, footboard, or sides.

[0003] Currently, in addition to their positioning function, the limiting structure of these mattresses often integrates electrical components such as indicator lights, serving both decorative and nighttime guidance purposes. However, due to installation constraints, the connecting cables for these electrical components are often exposed on the outside of the mattress. This not only results in messy wiring and an unsightly appearance, but also makes the cables prone to wear and tear and insulation cracking during repeated lifting and bending of the bed board, potentially leading to safety issues such as electrical leakage and wiring faults. Furthermore, the exposed cables can interfere with the movement of the mattress, affecting the stability of the smart bed's operation.

[0004] Therefore, there is an urgent need for a mattress limiting device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a mattress limiting device that not only has a limiting function but also integrates electrical components. It can complete signal transmission without the need for exposed cables, avoiding safety issues such as leakage and circuit failure, and improving the aesthetics and operational stability of the smart bed.

[0006] To achieve this objective, the present invention adopts the following technical solution: A mattress limiting device is provided, comprising: A first electrical component has a first housing and a first signal processing unit, wherein the first signal processing unit is at least partially disposed within the first housing; The second electrical component has a second housing and a second signal processing unit, the second signal processing unit being at least partially disposed within the second housing; The limiting rod has a first signal transmission part; The mounting base has a second signal transmission section; The limiting rod is connected to the first housing and the mounting base respectively, the first signal transmission part is connected to the first signal processing part and the second signal transmission part respectively, the mounting base is connected to the second housing, and the second signal transmission part is connected to the second signal processing part.

[0011] Optionally, the mattress limiting device also includes a signal transmission component. The first housing is provided with a first mounting hole, and the first mounting part is provided with a second mounting hole. The signal transmission component passes through the first mounting hole and the second mounting hole in sequence and is signal connected to the first signal processing part and the first signal transmission part, respectively.

[0012] Optionally, the first housing includes a receiving member having a receiving cavity, wherein when the limiting rod is disposed on the receiving member, the first mounting portion is at least partially disposed within the receiving cavity.

[0013] Optionally, the receiving member has a limiting cavity communicating with the receiving cavity, and the limiting rod includes an extension connected to the first mounting portion.

This simplifies the overall assembly process of the smart bed and reduces its overall manufacturing cost. The limiting rod connects to a mounting base, which in turn connects to the second outer shell, allowing the first electrical component to reliably connect to the second electrical component via the limiting rod and mounting base. Simultaneously, the first signal processing unit can be signal-connected to the second signal transmission unit via a first signal transmission unit, and the second signal transmission unit is in turn signal-connected to the second signal processing unit. This allows signals to be transmitted between the first and second signal processing units without the need for additional signal transmission structures. Compared to existing technologies, the mattress limiting device provided by this invention not only has a limiting function but also integrates electrical components, and it eliminates the need for exposed cables to complete signal transmission, avoiding safety issues such as leakage and wiring faults, and improving the aesthetics and operational stability of the smart bed.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0023] like Figures 1 to 6 As shown, this embodiment provides a mattress limiting device that not only has a limiting function but also integrates electrical components. It can complete signal transmission without the need for exposed cables, avoiding safety issues such as leakage and circuit failure, and improving the aesthetics and operational stability of the smart bed.

[0024] See Figure 1 The mattress limiting device includes a first electrical component 100, a second electrical component 200, a limiting rod 300, and a mounting base 400. The first electrical component 100 has a first housing 110 and a first signal processing unit 120, with the first signal processing unit 120 at least partially disposed within the first housing 110. The second electrical component 200 has a second housing 210 and a second signal processing unit 220, with the second signal processing unit 220 at least partially disposed within the second housing 210. The limiting rod 300 has a first signal transmitting part 310. The mounting base 400 has a second signal transmitting part 410. The limiting rod 300 is connected to the first housing 110 and the mounting base 400, respectively. The first signal transmitting part 310 is signal-connected to the first signal processing unit 120 and the second signal transmitting part 410, respectively. The mounting base 400 is connected to the second housing 210, and the second signal transmitting part 410 is signal-connected to the second signal processing unit 220.

[0025] The mattress limiting device provided in this embodiment, after the first housing 110 is connected to the limiting rod 300, the limiting rod 300, in addition to its limiting function, also serves to connect the first electrical component 100, realizing the integrated function of limiting and electrical components. This helps to simplify the overall assembly process of the smart bed and reduce the overall manufacturing cost of the smart bed. The limiting rod 300 is connected to the mounting base 400, and the mounting base 400 is connected to the second housing 210, so that the first electrical component 100 can be reliably connected to the second electrical component 200 through the limiting rod 300 and the mounting base 400. At the same time, the first signal processing unit 120 can be signal-connected to the second signal transmission unit 410 through the first signal transmission unit 310, and the second signal transmission unit 410 is signal-connected to the second signal processing unit 220. This allows signals to be transmitted between the first signal processing unit 120 and the second signal processing unit 220 through the first signal transmission unit 310 and the second signal transmission unit 410, without the need for an additional signal transmission structure. Compared with the prior art, the mattress limiting device provided in this embodiment not only has a limiting function, but also integrates electrical components. It can complete signal transmission without the need for exposed cables, avoiding safety issues such as leakage and circuit failure, and improving the aesthetics and operational stability of the smart bed.

[0026] For example, the first electrical component 100 includes, but is not limited to, a lamp, a buzzer, and a sensor, and the second electrical component 200 includes, but is not limited to, a controller and a power supply.

[0027] Optionally, see Figure 2 The device includes two limit rods 300 and two mounting bases 400, each corresponding to a different mounting base 400. Both limit rods 300 are connected to the first housing 110, and both mounting bases 400 are connected to the second housing 210. The first signal processing unit 120 is signal-connected to both first signal transmission units 310, and each first signal transmission unit 310 is signal-connected to a corresponding second signal transmission unit 410. The second signal processing unit 220 is signal-connected to both second signal transmission units 410. This configuration allows signals to be transmitted sequentially from the second signal processing unit 220 through one second signal transmission unit 410 and one first signal transmission unit 310 to the first signal processing unit 120, and then sequentially from the first signal processing unit 120 through another first signal transmission unit 310 and another second signal transmission unit 410 to the second signal processing unit 220. This partitioning of the signal transmission path between the first and second signal processing units 120 significantly improves the signal transmission safety of the mattress limiting device.

[0028] In this embodiment, see Figure 2The first signal processing unit 120 includes a first positive processing terminal 121 and a first negative processing terminal 122. One of the two first signal transmission units 310 includes a first positive transmission unit 311, and the other of the two first signal transmission units 310 includes a first negative transmission unit 312. One of the two second signal transmission units 410 includes a second positive transmission unit 411, and the other of the two second signal transmission units 410 includes a second negative transmission unit 412. The second signal processing unit 220 includes a second positive processing terminal 221 and a second negative processing terminal 222. The second positive processing terminal 221 is electrically connected to the second positive conducting part 411, the second positive conducting part 411 is electrically connected to the first positive conducting part 311, the first positive conducting part 311 is electrically connected to the first positive processing terminal 121, the first negative processing terminal 122 is electrically connected to the first negative conducting part 312, the first negative conducting part 312 is electrically connected to the second negative conducting part 412, and the second negative conducting part 412 is electrically connected to the second negative processing terminal 222. An electrical signal can be transmitted from the second positive processing terminal 221 sequentially through the second positive conducting part 411 and the first positive conducting part 311 to the first positive processing terminal 121, and then from the first negative processing terminal 122 sequentially through the first negative conducting part 312 and the second negative conducting part 412 to the second negative processing terminal 222.

[0029] For example, the first positive conductive part 311, the second positive conductive part 411, the first negative conductive part 312 and the second negative conductive part 412 all include connecting wires; or, the first positive conductive part 311, the second positive conductive part 411, the first negative conductive part 312 and the second negative conductive part 412 all include conductive parts.

[0030] The conductive part includes, but is not limited to, a conductive coating, which is applied to the surfaces of the first positive electrode conductive part 311, the second positive electrode conductive part 411, the first negative electrode conductive part 312, and the second negative electrode conductive part 412.

[0031] For example, the second signal processing unit 220 further includes a circuit board, the second positive processing terminal 221 includes a positive wire, the second negative processing terminal 222 includes a negative wire, one end of the positive wire is electrically connected to the second positive conducting part 411 and the other end is electrically connected to the circuit board, one end of the negative wire is electrically connected to the second negative conducting part 412 and the other end is electrically connected to the circuit board.

[0032] For example, the first signal transmission unit 310 includes a circuit board, the first positive terminal 121 is the positive terminal of the circuit board, and the first negative terminal 122 is the negative terminal of the circuit board.

[0033] Optionally, see Figure 1 and Figure 3The limiting rod 300 includes a first mounting part 320, a limiting part 330, and a second mounting part 340 connected in sequence. The first mounting part 320 is connected to the first outer shell 110, and the second mounting part 340 is connected to the mounting base 400. This arrangement allows the limiting rod 300 to connect to both the first outer shell 110 and the mounting base 400 via the first mounting part 320 and the second mounting part 340, respectively. The limiting part 330, located between the first mounting part 320 and the second mounting part 340, can contact the mattress to limit its slippage and arching, thus reliably limiting the mattress's position.

[0034] For example, the first signal transmission section 310 includes connecting wires, and connecting wires are provided on the first mounting section 320, the limiting section 330, and the second mounting section 340, and the connecting wires are connected to each other; or, the first signal transmission section 310 includes conductive parts, and conductive parts are provided on the outer surfaces of the first mounting section 320, the limiting section 330, and the second mounting section 340, and the conductive parts are in contact with each other. This arrangement allows electrical signals to be transmitted from the first signal processing section 120 to the second signal transmission section 410 via the first mounting section 320, the limiting section 330, and the second mounting section 340.

[0035] Specifically, see Figure 1 and Figure 3 The mounting base 400 is mounted on the bed board. The limiting part 330 includes a first limiting segment 331, a second limiting segment 332, and a third limiting segment 333 connected in sequence. The first limiting segment 331 is connected to the first mounting part 320, and the third limiting segment 333 is connected to the second mounting part 340. The third limiting segment 333 extends along the length direction of the mattress, the second limiting segment 332 extends along the thickness direction of the mattress, and the first limiting segment 331 extends along the width direction of the mattress. A multi-dimensional limiting space is formed between the first limiting segment 331, the second limiting segment 332, and the third limiting segment 333. This limiting space can reliably limit the movement of the mattress along its length direction.

[0036] In some embodiments, see Figure 1 and Figure 3 There are two limit rods 300 and two mounting bases 400. The second mounting part 340 of the two limit rods 300 is connected to the two mounting bases 400 in a one-to-one correspondence. The first mounting part 320 of the two limit rods 300 is connected to the first outer shell 110. The two mounting bases 400 are connected to the second outer shell 210.

[0037] In some embodiments, see Figure 4The mounting base 400 has an inwardly recessed mounting groove 420, and the second mounting part 340 is disposed in the mounting groove 420. The second mounting part 340 is disposed in the mounting groove 420, which can realize the precise positioning and reliable limiting of the second mounting part 340 and the mounting base 400, effectively preventing the limiting rod 300 from shifting, rotating or moving relative to the mounting base 400 during the limiting process; at the same time, the mounting groove 420 has a guiding function, which can reduce the difficulty of assembling the second mounting part 340 and the mounting base 400, and improve the overall assembly efficiency of the mattress limiting device.

[0038] Specifically, see Figure 4 The mounting groove 420 has a mounting surface 421 that contacts the outside, and the second signal transmitting part 410 is at least partially disposed on the mounting surface 421. This arrangement allows the second signal transmitting part 410 to be located on the surface of the mounting groove 420, at which point the first signal transmitting part 310 can transmit signals between itself by contacting the second signal transmitting part 410.

[0039] For example, see Figure 4 The mounting surface 421 is the groove wall of the mounting groove 420. The first signal transmission part 310 is partially disposed on the second mounting part 340. The second signal transmission part 410 is disposed on the mounting surface 421. The second mounting part 340 can be embedded in the mounting groove 420 and fit against the groove wall of the mounting groove 420. The first signal transmission part 310 and the second signal transmission part 410 are connected by signals.

[0040] In this embodiment, both the first signal conducting part 310 and the second signal conducting part 410 include conductive parts. The conductive part of the first signal conducting part 310 is disposed on the outer surface of the limiting rod 300, and the conductive part of the second signal conducting part 410 is disposed on the mounting surface 421. After the conductive parts of the first signal conducting part 310 and the conductive parts of the second signal conducting part 410 come into contact, an electrical signal connection between the first signal conducting part 310 and the second signal conducting part 410 can be realized. In other embodiments, both the first signal conducting part 310 and the second signal conducting part 410 include connecting wires. The end of the connecting wire of the first signal conducting part 310 is located at the second mounting part 340, and the end of the connecting wire of the second signal conducting part 410 is located at the mounting surface 421. When the surface of the second mounting part 340 comes into contact with the mounting surface 421, the ends of the two connecting wires are connected, thereby realizing an electrical signal connection between the first signal conducting part 310 and the second signal conducting part 410.

[0041] In some embodiments, see Figure 4The mounting base 400 has multiple mounting slots 420, and the second mounting part 340 can be selectively installed in any of the mounting slots 420. This arrangement allows the limiting rod 300 to adjust its position on the bed board by adjusting its connection position with the mounting base 400. This not only allows for flexible adjustment of the maximum displacement of the mattress relative to the bed board, but also allows for adjustment of its connection position with the bed board based on the position it limits the mattress, thus improving the flexibility of the mattress limiting device in limiting the mattress.

[0042] In some embodiments, see Figure 4 The mounting base 400 has an inwardly recessed abutment surface 430, which is inclined at a preset angle. The limiting part 330 at least partially abuts against the abutment surface 430. When the second mounting part 340 is installed into the mounting groove 420, the limiting part 330 abuts against the abutment surface 430. The abutment surface 430 is inclined relative to the bed board, so that the limiting part 330 is also inclined relative to the bed board. A gap will be generated between the limiting rod 300 and the bed board surface, which effectively avoids wear and collision between the limiting rod 300 and the bed board surface when the mattress moves, thus improving the overall aesthetics and service life of the smart bed.

[0043] For example, the preset angle is the angle between the contact surface 430 and the bed board, which is in the range of 5° to 10°.

[0044] In this embodiment, the contact surface 430 is connected to the mounting surface 421, so that the limiting part 330 connected to the second mounting part 340 can smoothly contact the contact surface 430.

[0045] Specifically, see Figure 3 and Figure 4 The limiting part 330 includes a first limiting segment 331, a second limiting segment 332 and a third limiting segment 333 connected in sequence. The first limiting segment 331 is connected to the first mounting part 320, the third limiting segment 333 is connected to the second mounting part 340, and the third limiting segment 333 abuts against the contact surface 430.

[0046] In this embodiment, the second signal transmission part 410 is at least partially disposed on the contact surface 430.

[0047] Specifically, when the second signal transmission part 410 includes a connecting wire, at least a portion of the connecting wire is embedded in the contact surface 430; when the second signal transmission part 410 includes a conductive part, at least a portion of the conductive part is disposed on the contact surface 430.

[0048] Optionally, see Figure 5The mattress limiting device also includes a signal transmitter 500. The first housing 110 has a first mounting hole 111, and the first mounting portion 320 has a second mounting hole 321. The signal transmitter 500 passes through the first mounting hole 111 and the second mounting hole 321 sequentially, and is respectively connected to the first signal processing unit 120 and the first signal transmitting unit 310. The first mounting hole 111 provides space for the signal transmitter 500 to be installed on the first housing 110, and the second mounting hole 321 provides space for the signal transmitter 500 to be installed on the first mounting portion 320, allowing the signal transmitter 500 to connect with the first housing 110 and the first mounting portion 320. After the signal transmitter 500 is connected to the first housing 110 and the first mounting portion 320, the first signal processing unit 120 can connect to the first signal transmitting unit 310 through the signal transmitter 500, thereby realizing signal transmission between the first electrical component 100 and the limiting rod 300.

[0049] Specifically, the signal transmission component 500 is made of metal and is connected to the first signal processing unit 120 and the first signal transmission unit 310 by welding, thereby transmitting electrical signals between the first signal processing unit 120 and the first signal transmission unit 310.

[0050] For example, the signal conductor 500 uses a screw, the shank of which passes through the first mounting hole 111 and the second mounting hole 321.

[0051] For example, see Figure 5 The second mounting hole 321 penetrates the first mounting portion 320 radially, and the signal transmission element 500 passes through the second mounting hole 321.

[0052] In this embodiment, see Figure 5 The first housing 110 includes a receiving member 130, which has a receiving cavity 131. When the limiting rod 300 is disposed on the receiving member 130, the first mounting part 320 is at least partially disposed within the receiving cavity 131. This arrangement ensures that the sidewall of the receiving cavity 131 exerts not only a radial supporting force on the first mounting part 320 but also an axial frictional force. Under the action of these two forces, the first mounting part 320 can be reliably mounted on the receiving member 130, achieving a stable connection between the limiting rod 300 and the first housing 110, and improving the reliability of the first electrical component 100 mounted on the limiting rod 300.

[0053] For example, the receiving member 130 is provided with a receiving groove or receiving hole, and the receiving cavity 131 is the inner cavity of the receiving groove or receiving hole, and the first mounting part 320 is inserted into or passes through the receiving cavity 131.

[0054] In some embodiments, see Figure 5 and Figure 6 The receiving member 130 has a limiting cavity 132 communicating with the receiving cavity 131. The limiting rod 300 includes an extension 350 connected to the first mounting portion 320. When the limiting rod 300 is disposed in the receiving member 130, the extension 350 is at least partially disposed within the limiting cavity 132. The provision of the extension 350 and the limiting cavity 132 increases the length of the assembly fit between the limiting rod 300 and the first housing 110. This not only helps to enhance the mutual constraint force between the limiting rod 300 and the first housing 110, making it less likely for the limiting rod 300 to move or rotate relative to the first housing 110, thus improving the reliability of the connection between the limiting rod 300 and the first electrical component 100, but also expands the stress area of ​​the limiting rod 300 and the first housing 110, effectively avoiding stress concentration, making the connection between the limiting rod 300 and the first housing 110 less prone to damage, and extending the service life of the mattress limiting device.

[0055] Specifically, see Figure 5 and Figure 6 The extension 350 is angled to the first mounting portion 320. The receiving cavity 131 extends along the extension direction of the first mounting portion 320, and the limiting cavity 132 extends along the extension direction of the extension 350. The extension 350 is located on the side of the first mounting portion 320 away from the limiting portion 330. This arrangement creates a bent shape between the extension 350 and the first mounting portion 320. This shape distributes the connection points between the limiting rod 300 and the first housing 110 in different orientations. This not only enables multi-dimensional constraints between the limiting rod 300 and the first housing 110, such as rotation, axial movement, and radial movement, but also compensates for the fit gap between the limiting rod 300 and the first housing 110, significantly improving the reliability of the connection between the limiting rod 300 and the first electrical component 100.

[0056] Optionally, see Figure 1 and Figure 4 The mounting base 400 has an outwardly protruding positioning portion 440, and the second outer shell 210 includes a positioning ring 230, which is sleeved on the positioning portion 440. The protruding positioning portion 440 can be wrapped by the positioning ring 230, which not only achieves a reliable connection between the second outer shell 210 and the mounting base 400, but also allows the mounting base 400 to be positioned and installed on the bed board through the positioning portion 440, thereby improving the stability of the mounting base 400.

[0057] For example, see Figure 4 The positioning part 440 is disposed on the bottom surface of the mounting base 400, the bottom surface of the mounting base 400 is in contact with the bed board, the positioning ring 230 is located below the bed board, and the positioning part 440 passes through the bed board and the positioning ring 230.

[0058] In this embodiment, see Figure 2 and Figure 4There are two mounting bases 400 and two positioning rings 230, with each positioning ring 230 corresponding to a positioning part 440 of the two mounting bases 400.
