Description

Technical Field

[0001] The utility model relates to the field of bedding, and particularly to a control box and a bed using the same. Background Art

[0002] The existing bed includes a bed body, a mattress with air bags inside, and a control box for controlling the air pressure in the air bags. The control box includes a housing and an air pump, a control board group, and a solenoid valve group arranged inside the housing. The solenoid valve group is fixedly connected to the inside of the housing through a bracket. Since the solenoid valve group includes a plurality of valves arranged densely, the valves are switched between open and closed states through circuit control, so that a large amount of heat will be generated after the valves operate for a long time, resulting in the valves being affected by their own high temperature and affecting the reliability of use, further shortening the service life of the valves and affecting the use experience. Content of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model provides a control box and a bed using the same, and a heat sink is arranged on the bracket for fixedly connecting the solenoid valve group, so that the heat generated by the operation of the solenoid valve group can be effectively dissipated, ensuring that the solenoid valve group is maintained within a suitable temperature range, improving the operation reliability of the solenoid valve group, prolonging the service life, and improving the use experience.

[0004] The utility model is realized in the following way: A control box includes a housing with an internal assembly cavity, a suspension arranged in the assembly cavity, and a solenoid valve group and an air pump assembly suspended on the suspension. The solenoid valve group is suspended on the suspension through a bracket, and a heat sink is arranged on the surface of the bracket. The bracket absorbs the heat generated by the operation of the solenoid valve group and dissipates it outward through the heat sink. By arranging a heat sink on the bracket for fixedly connecting the solenoid valve group, the bracket absorbs the heat from the solenoid valve group and dissipates it outward through the heat sink, ensuring that the solenoid valve group is maintained within a suitable temperature range, not only improving the operation reliability of the solenoid valve group, but also prolonging the service life and improving the use experience.

[0005] Preferably, the bracket includes two parallel end plates and a bottom plate bridging between the bottom edges of the end plates, so as to form an upwardly open installation groove in the middle of the bracket for the solenoid valve group to be inserted and assembled, which not only ensures that the structural strength of the bracket meets the installation requirements of the solenoid valve group, but also can limit the displacement of the solenoid valve group by setting the end plates and the bottom plate, improving the connection reliability.

[0006] Preferably, mounting holes are provided on both end plates, and a flat heat absorption surface is formed on the inner side wall of the end plate. After the solenoid valve group is inserted into the installation groove, it is fixedly connected to the corresponding heat absorption surface through a fastener passing through the mounting hole. The solenoid valve group is fixedly connected to the end plate through a fastener screwed into the mounting hole, so that the heat absorption surface is closely attached to the solenoid valve group, effectively improving the heat transfer efficiency between the two, and ensuring that the heat on the solenoid valve group can be effectively transferred to the end plate.

[0007] Preferably, the heat sink is disposed on the outer sidewall of the end plate facing away from the mounting groove. The heat sink and the solenoid valve group are located on both sides of the end plate, ensuring that the heat generated on the solenoid valve group can be transferred to the heat sink through the end plate, thereby facilitating the dissipation of heat through the heat sink to improve the heat dissipation efficiency.

[0008] Preferably, the heat sink is vertically arranged, and the length of the heat sink matches the height of the end plate. The heat sink vertically penetrates the end plate, increasing the exposed area by increasing the length of the heat sink, thereby improving the heat effect and ensuring that the heat in each area of the end plate can be diffused outward by the corresponding heat sink.

[0009] Preferably, the heat sinks are strip-shaped and are equally spaced and parallel to each other, ensuring that a channel for air flow is reserved between adjacent heat sinks to ensure that each heat sink has a good heat dissipation effect.

[0010] Preferably, a heat dissipation hole is opened in the middle of the bottom plate. The bottom plate not only plays a role in connecting the end plate to ensure that the structural strength of the bracket meets the requirements for fixedly connecting the solenoid valve group, but also facilitates the bottom surface of the solenoid valve group to be exposed through the heat dissipation hole and dissipate heat outward.

[0011] Preferably, ear plates that can be connected to the suspension are provided in the middle of both sides of the bottom plate. A heat dissipation opening for the solenoid valve group to be exposed is formed between the ear plates and the end plate. The suspension is installed in the assembly cavity, and the bracket is suspended on the suspension through a damping belt provided on the ear plates. The ear plates and the end plate are independently arranged, so that a heat dissipation opening is formed between the side edges of the ear plates and the adjacent end plate, and the side part of the solenoid valve group is exposed through the heat dissipation opening and dissipates heat outward.

[0012] Preferably, the bracket is integrally formed by bending a metal plate, which not only ensures that the bracket has good heat conduction efficiency but also ensures that the bracket has good structural strength.

[0013] Preferably, a control board group is provided in the housing. The control board group includes a main control board and a sub-control board that are separately arranged. An isolation cavity isolated from the assembly cavity is provided in the housing. The main control board is arranged on the suspension in the assembly cavity, and the sub-control board is installed in the isolation cavity to limit the transmission of noise generated in the assembly cavity to the outside through the isolation cavity. The main control board and the sub-control board are separately arranged, which not only protects the main control board, but also facilitates the connection of the sub-control board to the external pipeline, and also prevents the vibration generated by the operation of the components inside the assembly cavity from being transmitted outward through the control board group, effectively reducing noise.

[0014] Preferably, a cantilever is provided in the assembly cavity. Both ends of the cantilever are fixedly connected to the cavity wall of the assembly cavity, and the middle part is fixedly connected to the suspension, so that the suspension is suspended in the assembly cavity through the cantilever. The suspension is fixedly connected to the assembly cavity through the cantilever, and the cantilever uses its own deformation to offset the vibration on the suspension, thereby reducing the noise generated by the vibration.

[0015] A bed using the control box includes a bed body and a mattress disposed on the bed body. The mattress is provided with upper massage air bags and lower support air bags. An installation frame is provided at the bottom of the rear end of the bed body, and the control box is disposed on the installation frame. The control box is disposed on the installation frame at the rear of the bed body, which is externally disposed relative to the mattress, effectively reducing the vibration of the mattress. It is also far from the user's head, effectively reducing the impact of the operating noise on the user's sleep and improving the use experience.

[0016] The beneficial effects of the present utility model: A heat sink is provided on the bracket for fixedly connecting the solenoid valve group. The bracket absorbs the heat from the solenoid valve group and dissipates it outward through the heat sink, ensuring that the solenoid valve group is maintained within an appropriate temperature range, which not only improves the operating reliability of the solenoid valve group but also extends its service life and improves the use experience.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the essential features of the present utility model in conjunction with the accompanying drawings of the specification and the specific embodiments.

[0024] Embodiment 1:

[0025] This embodiment provides a control box.

[0026] As Figure 1 And 2A control box shown in the figure includes a housing 1 with an internal assembly cavity, a suspension 2 arranged in the assembly cavity, and a solenoid valve group 3 and an air pump assembly 4 suspended on the suspension 2. The solenoid valve group 3 is suspended on the suspension 2 through a bracket 5. A heat sink 6 is arranged on the surface of the bracket 5. The bracket 5 absorbs the heat generated during the operation of the solenoid valve group 3 and diffuses it outward through the heat sink 6. By arranging the heat sink 6 on the bracket 5 for fixing the solenoid valve group 3, the bracket 5 absorbs the heat from the solenoid valve group 3 and diffuses it outward through the heat sink 6, ensuring that the solenoid valve group 3 is maintained within an appropriate temperature range, which not only improves the operating reliability of the solenoid valve group 3 but also extends its service life and enhances the user experience.

[0027] In this embodiment, the bracket 5 is integrally formed by bending a metal plate (as Figure 3 shown). The bracket 5 includes two parallel end plates 7, a bottom plate 8 bridging between the bottom edges of the end plates 7, and ear plates 12 arranged in the middle of both sides of the bottom plate 8 and connectable to the suspension 2. The end plates 7, the bottom plate 8, and the ear plates 12 enclose an upwardly exposed installation slot for inserting and assembling the solenoid valve group 3. The bracket 5 is integrally processed from a metal plate, which not only ensures that the bracket 5 has good thermal conductivity for facilitating heat diffusion but also ensures that the bracket 5 has good structural strength to ensure reliable connection between the solenoid valve group 3 and the suspension 2.

[0028] During installation, the solenoid valve group 3 is inserted into the installation slot and fits against the inner side wall of the end plate 7. A fastener passes through the installation hole 9 and is screwed and locked with the solenoid valve group 3 to make the solenoid valve group 3 closely fit against the heat-absorbing surface of the end plate 7. The ear plates 12 of the bracket 5 are suspended below the suspension 2 through a shock-absorbing belt, and the suspension 2 is fixedly connected to the assembly cavity through a cantilever 16.

[0029] After being installed in place, the heat generated during the operation of the solenoid valve group 3 can be transferred to the bracket 5 through the heat-absorbing surface, and the heat on the bracket 5 can be diffused outward through the heat sink 6, effectively reducing the temperature of the solenoid valve group 3. In addition, the solenoid valve group 3 is connected to the suspension 2 through a shock-absorbing belt, and the suspension 2 is connected to the housing 1 through a deformable cantilever 16, so that the vibration generated during the operation of the solenoid valve group 3 can be offset by the deformable shock-absorbing belt and the deformable cantilever 16 of the housing, effectively reducing the noise generated during the operation of the solenoid valve group 3.

[0030] In this embodiment, the end plates 7 are provided with mounting holes 9, and the inner side walls of the end plates 7 form a flat heat-absorbing surface. After the solenoid valve group 3 is inserted into the mounting groove, it is fixedly connected to the corresponding heat-absorbing surface through fasteners passing through the mounting holes 9. The solenoid valve group 3 has a flat side wall, and the size of the heat-absorbing surface is larger than the size of the side wall of the solenoid valve group 3, so that the side wall of the solenoid valve group 3 can be completely attached to the heat-absorbing surface, and the heat dissipation effect is improved by increasing the contact area between the two, thereby ensuring that the temperature of the solenoid valve group 3 is always maintained within the normal range, and ensuring the operating reliability of the solenoid valve group 3. A plurality of mounting holes 9 are provided on the end plate 7, and the number of mounting holes 9 is increased to increase the connection points, which plays a role in fixing the solenoid valve group 3 and prevents the solenoid valve group 3 from being offset or deflected.

[0031] In this embodiment, heat sinks 6 and heat absorbing surfaces are respectively provided on both sides of the end plate 7. The distance between the heat sink 6 and the heat absorbing surface is reduced to shorten the heat transfer distance on the bracket 5, thereby improving the heat transfer efficiency and ensuring that the heat absorbed by the heat absorbing surface can be diffused outward through the heat sink 6 as quickly as possible, thereby effectively reducing the operating temperature of the solenoid valve group 3.

[0032] In this embodiment, the heat sink 6 is arranged vertically, the length of the heat sink 6 matches the height of the end plate 7, and the heat sink 6 is in the shape of a long strip and is equidistantly arranged in parallel. The heat sink 6 is evenly spaced and covers the outer wall of the end plate 7, which increases the exposed area by increasing the number and length of the heat sink 6 to facilitate heat dissipation, and forms a ventilation channel between adjacent heat sinks 6 by equidistant arrangement, ensuring that the airflow flows through the ventilation channel and takes away the heat on the corresponding heat sink 6, ensuring that each heat sink 6 has a balanced heat dissipation efficiency.

[0033] In this embodiment, a heat dissipation hole 10 is provided in the middle of the bottom plate 8, and a heat dissipation port 11 for exposing the solenoid valve group 3 is formed between the ear plate 12 and the end plate 7. The heat dissipation hole 10 and the heat dissipation port 11 are provided to facilitate the partial surface exposure of the solenoid valve group 3, so that the solenoid valve group 3 can directly dissipate heat outward through the exposed surface. The size of the heat dissipation hole 10 and the heat dissipation port 11 is limited to ensure that the structural strength of the bracket 5 meets the requirements of fixing the solenoid valve group 3, thereby ensuring that the solenoid valve group 3 is reliably fixed.

[0034] In this embodiment, a control board group is provided inside the housing 1. The control board group includes a main control board 13 and a secondary control board 14 that are separately arranged. An isolation chamber 15 that is isolated from the assembly cavity is provided inside the housing 1. The main control board 13 is arranged on the suspension 2 inside the assembly cavity, and the secondary control board 14 is installed inside the isolation chamber 15 to limit the transmission of noise generated inside the assembly cavity to the outside through the isolation chamber 15. The main control board 13 is arranged inside the assembly cavity and fixedly connected to the suspension 2 for logical control. The secondary control board 14 is arranged inside the isolation chamber 15 for connecting external interfaces. The main control board 13 and the secondary control board 14 are connected by a flexible cable, effectively preventing the vibration on the suspension 2 from being transmitted to the secondary control board 14 through the main control board 13, and further preventing the noise inside the assembly cavity from being transmitted to the outside through the isolation chamber 15.

[0035] In this embodiment, a cantilever 16 is provided inside the assembly cavity. Both ends of the cantilever 16 are fixedly connected to the cavity wall of the assembly cavity, and the middle part is fixedly connected to the suspension 2, so that the suspension 2 is suspended inside the assembly cavity through the cantilever 16. The cantilever 16 is a long strip-shaped elastic steel bar, and the elastic steel bar can use its own deformation to offset the vibration of the suspension 2, thereby preventing the vibration on the suspension 2 from being transmitted to the housing 1, and further preventing the housing 1 from generating noise due to vibration.

[0036] Embodiment Two:

[0037] Compared with Embodiment One, this embodiment provides a bed.

[0038] As Figure 4 and 5 shown in the figure, the bed includes a bed body 17 and a mattress 18 arranged on the bed body 17. An upper massage airbag 21 and a lower support airbag 22 are provided inside the mattress 18. An installation frame 19 is provided at the bottom of the rear end of the bed body 17, and the control box 20 is arranged on the installation frame 19. The control box 20 is arranged on the installation frame 19 at the rear of the bed body 17, which is both externally placed outside the mattress 18, effectively reducing the vibration of the mattress 18, and also far away from the user's head, effectively reducing the impact of the operating noise on the user's sleep and improving the use experience.

[0039] In this embodiment, a massage airbag 21 and a support airbag 22 are provided inside the mattress 18. The control box independently adjusts the air pressure inside the massage airbag 21 and the support airbag 22, so that the mattress 18 has the functions of adjustable hardness and adjustable massage stimulation, effectively improving the use comfort and enhancing the use experience.

[0040] The other structures and effects of the control box in this embodiment are the same as those in Embodiment One, and will not be elaborated here.
