Description

Technical Field

[0001] The invention relates to the field of bedding, and in particular to an air-circuit connection belt and a bed. Background Art

[0002] The existing bed includes a bed frame and a mattress arranged on the bed frame. The mattress includes a cushion body, a control box arranged on the bed frame, functional parts arranged on the cushion body, and an adapter box arranged on the rear edge of the cushion body. The adapter box plays the role of connecting the functional parts and the control box. The functional parts include a sensor belt, a heating plate, a button, and an air bag, etc. The control box is connected to the functional parts in the mattress through pipelines. The control box is provided with a control panel and an air pump assembly. The pipeline includes an energized wire and a ventilated air pipe. The control panel is connected to the corresponding functional parts through the wire passing through the adapter box to ensure the normal operation of the functional parts. The air pump assembly is connected to the air bag through the air pipe passing through the adapter box. The softness and hardness are adjusted by adjusting the air pressure in the air bag.

[0003] To facilitate assembly, the control box can be detachably installed on the bed frame, and the control box and the adapter box are connected by pipelines. Due to the wide variety of corresponding functional parts, the control box and the corresponding functional parts are connected by corresponding pipelines, resulting in a complicated pipeline structure between the control box and the adapter box. Not only do they need to be disassembled and connected one by one, which increases the workload of disassembly and assembly, but the pipelines are also easily entangled and knotted because they are set independently, causing damage to the pipelines due to friction and pulling, shortening the service life of the pipelines and affecting the user experience. Summary of the invention

[0004] In order to address the deficiencies in the prior art, the present invention provides an air circuit connecting belt and bed, with closed through holes and open through grooves on the belt body, the through holes forming an air path, and the through grooves clamping and positioning the wires, which not only facilitates disassembly and maintenance, but also ensures that the pipelines will not be entangled and damaged, thereby improving the user experience.

[0005] The present invention is realized in the following manner: a gas circuit connection belt, comprising a long strip body and a connector arranged at the end of the strip body, the strip body is provided with a gas path and a circuit path that are arranged through along its length direction, the strip body is provided with a through hole that is isolated from the outside and forms the gas path, the surface of the strip body is provided with an exposed through groove, the through groove forms a circuit path for the wire to be embedded and laid, and the ends of the gas path and the circuit path are connected to the outside through corresponding connectors. The strip body includes a built-in through hole and an exposed through groove, the through hole is used to form a gas path for conveying airflow, and the through groove is used to clamp and position the wire for transmitting power and signals, which is convenient for disassembly and maintenance, and also ensures that the pipelines will not be entangled and damaged, thereby improving the user experience.

[0006] Preferably, the air passages are multiple and arranged side by side along the width of the belt body, and adjacent air passages are equidistantly spaced. The air passages are multiple and independently arranged, which is convenient for adjusting the air pressure of different airbags. Adjacent air passages are equidistantly spaced to ensure that the wall thickness of each air passage meets the sealing requirements and improve the reliability of use.

[0007] Preferably, the circuit channels are multiple and arranged between adjacent gas channels, so that the adjacent circuit channels are equally spaced. The circuit channels are arranged between adjacent gas channels, which can not only utilize the space between adjacent gas channels to improve the space utilization efficiency in the belt body, but also increase the distance between the circuit channels to ensure that the wires are separated.

[0008] Preferably, the cross-sectional profile of the through slot is in the shape of a small opening and a large cavity, the cross-sectional profile of the through slot wall is in the shape of an arc, and the diameter of the wire is greater than the slot width of the through slot, so as to limit the wire from escaping from the through slot. The cross-sectional profile of the through slot matches the cross-sectional profile of the wire, which not only ensures that the wire can be tightly wrapped in the through slot, but also effectively prevents the through slot from being deformed due to being unable to accommodate the wire, and ensures that the belt body profile will not be deformed. The through slot is in the shape of a small opening and a large cavity, and the smaller slot is used to clamp and limit the wire, so as to prevent the wire from escaping from the through slot.

[0009] Preferably, the notch of the through slot is opened on the bottom surface of the belt body. The through slot is arranged on the bottom surface of the belt body, which not only facilitates the wires to be embedded in the through slot in the same direction, improving assembly convenience, but also serves to cover the notch of the through slot, improving aesthetics.

[0010] Preferably, the wall spacing between adjacent through holes is greater than the diameter of the through slot to increase the wall thickness of the through hole. By increasing the wall thickness of the through hole, the sealing performance is improved, the belt body is prevented from being broken and leaking due to frequent bending, and the service life of the belt body is extended.

[0011] Preferably, the belt body is made of a sealing material so that the middle section of the through hole is sealed and isolated from the external space. During processing, the belt body forms a through hole that is sealed from the outside world to ensure that the airflow will not leak during the transportation process.

[0012] Preferably, the belt body is made of a flexible material so that the middle section of the belt body can be twisted and deformed. The belt body can be bent and deformed, so that the connectors at both ends of the belt body can be fixed at the preset positions in any direction, which is convenient for the belt body to bridge between the control box and the adapter box, and can also ensure the connection reliability of the belt body when the control box and the adapter box are relatively offset.

[0013] Preferably, the belt body is provided with a C-shaped band hoop, the inner edge profile of the band hoop matches the cross-sectional profile of the belt body, and the two ends of the band hoop are bent to form a limiting portion that wraps the side edge of the belt body to limit the expansion of the through slot. The band hoop is placed on the belt body, which not only clamps the belt body to prevent the belt body profile from being deformed, but also limits the expansion of the through slot, ensuring that the wire is reliably clamped in the through slot and the wire is laid along the belt body.

[0014] Preferably, the connector includes a shell and a connection seat inserted in the shell, the connection seat includes a fixing plate and a gas nozzle and a through hole arranged on the fixing plate, the inner connection end of the gas nozzle is sealed and plugged with the corresponding gas path channel port, the outer extension end extends outward and is exposed, and the fastener passes through the through hole and is fixed to the shell. The shell is sleeved on the connection seat, and the fixing plate is not only firmly connected to the shell through the fastener passing through the through hole, but also used to fix each gas nozzle to ensure that the relative position between each gas nozzle is fixed. One end of the gas nozzle is inserted and connected with the corresponding through hole port on the belt body, and the other end can be sealed and connected after the connection seat is fixed to the corresponding device, thereby ensuring that the control box and the adapter box achieve gas conduction through the belt body.

[0015] Preferably, the air nozzle is a straight plug nozzle with a straight axis, and the axis of the outer end and the inner end of the straight plug nozzle are arranged to overlap each other. The axis of the straight plug nozzle is straight, so that the plugging direction of the end of the belt body is consistent with its axis direction, which is convenient for plugging and use.

[0016] Preferably, the air nozzle is a curved plug nozzle with an L-shaped axis, so that the axis of the outer extension end and the inner connection end of the curved plug nozzle are perpendicular to each other. The curved plug nozzle is L-shaped, so that the insertion direction of the end of the belt body is perpendicular to the axis direction of the belt body, which not only ensures that the belt body is sealed and plugged in the preset position, but also ensures that the belt body can be laid along the surface of the equipment, effectively reducing the space required to accommodate the belt body and facilitating the laying of the belt body.

[0017] Preferably, a through cavity for accommodating the air nozzle is provided in the housing, and the connecting seat is inserted in the through cavity and fixed to the housing through a fixing plate. The through cavity is used to accommodate the connecting seat and facilitate the passage of the air path and connection with external equipment, and the housing is used to protect and shield the connecting seat.

[0018] A bed comprises a bed frame and a mattress, a control box is installed on the mattress, a functional part and an adapter box connected to the functional part are arranged on the mattress, and the control box and the adapter box are connected by the air circuit connection belt, so that the control box and the adapter box are connected through the air path and the circuit path. The control box and the adapter box are effectively connected by the air circuit connection belt, which not only ensures that the control box can control the air pressure of the airbag in the mattress through the air path, thereby adjusting the hardness of the mattress, but also ensures that the control box can be connected to the live functional parts in the mattress through the circuit path, thereby improving the user experience.

[0019] The beneficial effects of the present invention are as follows: the belt body includes built-in through holes and exposed through grooves, and the through holes are used to form an air path for conveying airflow, and the through grooves are used to position the wires used to transmit power and signals, which not only facilitates disassembly and maintenance, but also ensures that the pipelines will not be entangled or damaged, thereby improving the user experience.

[0029] The essential features of the present invention are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Embodiment 1:

[0031] This embodiment provides a gas circuit connection belt.

[0032] like Figure 1The illustrated air-circuit connection belt comprises a long strip-shaped belt body 1 and a connector 4 arranged at the end of the belt body 1. The belt body 1 is provided with an air path and a circuit path which are arranged through along its length direction. A through hole 2 which is isolated from the outside and forms the air path is provided in the belt body 1. An exposed through groove 3 is provided on the surface of the belt body 1. The through groove 3 forms a circuit path for the wire 5 to be embedded and laid. The ends of the air path and the circuit path are connected to the outside through the corresponding connector 4. The belt body 1 comprises a built-in through hole 2 and an exposed through groove 3. The through hole 2 is used to form an air path for conveying airflow, and the through groove 3 is used to clamp and position the wire 5 for transmitting power and signals. This is convenient for disassembly and maintenance, and ensures that the pipelines will not be entangled or damaged, thereby improving the user experience.

[0033] In this embodiment, the belt body 1 is integrally formed and is in the shape of a long strip. It can be cut according to the use requirements and equipped with a connector 4 to form the air circuit connection belt, which is convenient for batch processing and assembly. The belt body 1 is preferably made of polymer material, which is convenient for extrusion molding to ensure that each section of the belt body 1 has the same cross-sectional profile (such as Figure 2 As shown), it is convenient for users to cut according to their needs, and ensures that the cut belt body 1 has the same air path and circuit path layout. In a preferred solution, the belt body 1 is made of silicone material, which not only ensures that the belt body 1 has good sealing performance, ensures that the middle section of the through hole 2 is isolated and sealed from the external space, but also ensures that the belt body 1 has good deformation performance, ensures that the middle section of the belt body 1 can be twisted and deformed, so that the orientation of the two ends of the belt body 1 can cooperate with the corresponding connector 4 to move synchronously, and ensures that the belt body 1 has good elastic recovery performance, improves the sleeve sealing of the air path channel port and the corresponding air nozzle, improves the expansion and reset performance of the notch of the through slot 3, and effectively limits the wire 5 inserted into the through slot 3.

[0034] In this embodiment, the belt body 1 includes a plurality of air channels arranged side by side along its width and a circuit channel arranged between adjacent air channels, and the circuit channels and the air channels are arranged separately to ensure that they do not interfere with each other and ensure reliability in use. The air channels are used to convey airflow, and the circuit channels are used to lay wires 5, thereby facilitating power supply and signal transmission.

[0035] In this embodiment, the air passages are arranged along the width direction of the center line of the belt body 1, and adjacent air passages are equidistantly spaced, so that there is a large thickness between adjacent air passages and between the air passages and the outer peripheral wall of the belt body 1, ensuring that the wall thickness of each area around the through hole 2 meets the preset requirements, ensuring that the belt body 1 is soft and easy to bend, and ensuring that each section of the air passage has good sealing performance, preventing the belt body 1 from being locally damaged due to frequent bending.

[0036] In this embodiment, the circuit channels are multiple and are arranged between adjacent gas channels so that the adjacent circuit channels are equally spaced. Specifically, the belt body 1 includes four mutually parallel through holes 2 and three spaced through slots 3. The through holes 2 are opened in the middle of the belt body 1, and the axis of the through holes 2 coincides with the horizontal center line of the belt body 1. The through slots 3 are arranged at the lower position of the area between the adjacent through holes 2. The notches of the through slots 3 are opened on the bottom surface of the belt body 1, which effectively utilizes the space between the adjacent gas channels. During assembly, the connector 4 is inserted into the corresponding gas channel port at the corresponding end of the belt body 1 in a tight fit through the inner port of the air nozzle, so that the air nozzle is sealed and connected with the corresponding gas channel. The middle section of the wire 5 is embedded in the through slot 3, and the two ends are connected to the external equipment by passing through the corresponding connector 4. After installation, the wire 5 is laid along the belt body 1, which not only ensures that the wire 5 is linked with the belt body 1, but also uses the belt body 1 to cover and hide the wire 5, which plays a protective role on the wire 5 and prevents the wire 5 from being exposed and worn. In addition, the number and layout of the air channels and circuit channels on the belt body 1 can be set according to the use requirements, and can be integrally processed and formed when processing the belt body 1, which should also be regarded as a specific implementation of this embodiment.

[0037] In this embodiment, the distance between the walls of adjacent through holes 2 is greater than the diameter of the through slot 3 , so as to increase the wall thickness of the through hole 2 and further improve the sealing reliability of the through hole 2 .

[0038] In this embodiment, the cross-sectional profile of the gas path channel is circular, and its diameter can be set according to the preset air flow rate, so that the cross-sectional profile of the gas path channel meets the requirements of the air flow and improves the air flow transmission efficiency. The cross-sectional area and cross-sectional profile of the circuit channel can be pre-processed according to the size and cross-sectional shape of the pre-buried wire 5 to meet the requirements of the embedding and laying of the wire 5 and improve the reliability of the clamping and positioning.

[0039] In this embodiment, the cross-sectional profile of the through slot 3 is in the shape of a small opening and a large cavity, the cross-sectional profile of the slot wall of the through slot 3 is in the shape of an arc, and the diameter of the wire 5 is greater than the slot width of the through slot 3, so as to prevent the wire 5 from escaping from the through slot 3. The slot edge of the through slot 3 has a large thickness, which effectively increases the anti-deformation performance at the slot of the through slot 3, thereby effectively preventing the wire 5 from escaping from the through slot 3 due to the expansion of the slot of the through slot 3 under force.

[0040] In this embodiment, the belt body 1 is provided with a C-shaped belt hoop 6 (such as Figure 3As shown in the figure, the inner edge profile of the band hoop 6 matches the cross-sectional profile of the belt body 1, and the two ends of the band hoop 6 are bent to form a limiting portion that wraps the side edge of the belt body 1 to limit the expansion of the slot 3. The C-shaped band hoop 6 can be buckled on any section of the belt body 1, and the slot of the slot 3 is arranged toward the inner cavity of the band hoop 6, so that the slot 3 is blocked by the band hoop 6, which not only limits the wire 5, but also shapes the slot of the slot 3 to prevent the wire 5 from escaping from the slot 3 due to expansion. The belt body 1 can be provided with multiple band hoop 6 as needed to ensure that each section of the wire 5 is tightly embedded in the corresponding section of the slot 3.

[0041] In this embodiment, the connector 4 includes a shell 7 and a connection seat inserted in the shell 7, the connection seat includes a fixing plate 8 and a gas nozzle and a through hole 9 arranged on the fixing plate 8, the inner connection end of the gas nozzle is sealed and plugged with the corresponding gas path channel port, the outer extension end extends outward and is exposed, and the fastener passes through the through hole 9 and is fixed to the shell 7. The gas nozzle is tubular, the inner connection end of the gas nozzle is inserted in the port of the corresponding gas path channel, and the gas path channel port is tightly sleeved on the inner connection end by its own elasticity to ensure a sealed connection between the two. The outer extension ends of the gas nozzles on the connector 4 are equidistantly spaced and their axes are parallel to each other. When the connector 4 is plugged and installed along the axis direction of the outer extension end, the outer extension end of each gas nozzle can be synchronously plugged with the interface of the corresponding device, which is convenient for disassembly and maintenance and ensures the reliability of plug-in sealing.

[0042] In this embodiment, a through cavity for accommodating the gas nozzle is provided in the housing 7, and the connecting seat is inserted in the through cavity and fixedly connected to the housing 7 through a fixing plate 8. The fixing plate 8 is provided with a gas nozzle and a through hole 9, and the gas nozzle is vertically arranged on the fixing plate 8, ensuring that the fixing plate 8 can be attached to the cavity wall of the through cavity and fixedly locked by a fastener passing through the through hole 9, ensuring that the gas nozzle is fixed in the through cavity, and ensuring that the outer end of the gas nozzle is exposed to the outside through the cavity opening of the through cavity, so as to facilitate connection with the corresponding equipment.

[0043] In this embodiment, the connecting seat is provided with a mounting hole with a fastener. When in use, when the extended end of the air nozzle is inserted and connected with the corresponding device, the connecting seat is close to the surface of the device and is fixedly locked by the fastener passing through the mounting hole, ensuring that the extended end is tightly plugged into the interface of the corresponding device.

[0044] In this embodiment, the gas nozzle can be of various structures, which are used to connect with the interface of the corresponding equipment under different working conditions to ensure that the belt body 1 is laid along the preset path. The connectors 4 at both ends of the belt body 1 can be selected according to the use requirements, which should be regarded as the specific implementation of this embodiment. Specifically, the gas nozzle is a curved plug nozzle 11 with an L-shaped axis (such as Figure 4As shown), so that the axis of the outer extension end of the curved plug nozzle 11 and the inner connection end are perpendicular to each other, after installation, the end of the belt body 1 and the outer extension end of the air nozzle are perpendicular to each other, so that the belt body 1 can be laid along the surface of the corresponding equipment, effectively reducing the space required for the installation of the belt body 1; the air nozzle is a straight plug nozzle 10 with a straight axis (as shown Figure 5 As shown), the axis of the outer end of the straight plug nozzle 10 and the inner end are arranged to overlap each other. After installation, the end of the belt body 1 and the outer end of the air nozzle are coaxially arranged, so that the axis of the end of the belt body 1 is arranged in the same direction as the axis of the corresponding equipment interface, which is convenient for plugging and unplugging.
