[0040] The utility model aims to provide a berth which can maintain a constant temperature.

[0041] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0042] See also Figures 1 to 3 The present embodiment provides a constant temperature berth, comprising: a support shell 100, an air supply duct 200, an air supply control valve 300, an elastic support assembly 400 and a temperature control assembly; the air supply duct 200 is arranged inside the support shell 100, and has a plurality of air supply holes 210, and the air supply duct 200 is used to transport hot air into the support shell 100; the air supply control valve 300 is installed at the inlet end of the air supply duct 200, and is used to control the air volume entering the air supply duct 200; the elastic support assembly 400 is installed inside the support shell 100, and the extension direction of the elastic support assembly 400 is perpendicular to the bottom surface of the support shell 100; the thermal insulation pad 500 is laid on the elastic support assembly 400; the temperature control assembly comprises a controller 610 and a temperature sensor 620 arranged on the upper surface of the thermal insulation pad 500, the controller 610 is electrically connected to the air supply control valve and the temperature sensor 620 respectively, and the controller 610 is used to control the opening and closing of the air supply control.

[0043] Specifically, the support shell 100 is a strip shell structure, and a storage space is provided inside it for installing the remaining components of the constant temperature berth; the air supply duct 200 is an ordinary metal duct that can transport hot air. The air supply duct 200 is laid inside the support shell 100, and can transport the hot air output by equipment such as an external air conditioner or a diesel heater to the inside of the support shell 100, wherein the air supply holes 210 on the air supply duct 200 are the key factors to ensure the overall balanced heating of the berth, therefore, the air supply holes 210 can be evenly arranged on the circumference of the air supply duct 200; of course, in order to control the temperature of the berth not to be too high or too low, it is necessary to control the air supply to the inside of the support shell 100. In order to increase the amount of hot air delivered, an air supply control valve 300 is provided at the entrance of the air supply duct 200; in addition, in the present embodiment, an elastic support assembly 400 is installed in the bracket shell 100 as a supporting frame of the berth, and the internal space of the berth is supported by the elastic support assembly 400, so that the hot air can flow in the space inside the bracket shell 100, thereby heating the entire upper surface of the berth; of course, in order to prevent the heat in the bracket shell 100 from being lost too quickly, a layer of insulation pad 500 is laid on the upper surface of the elastic support assembly 400, wherein the insulation pad 500 covers the entire bracket shell 100 and completely wraps the elastic support assembly 400.

[0044] In the present embodiment, in order to be able to accurately control the temperature of the berth and maintain a constant temperature of the berth, a temperature control component is further provided, wherein the temperature control component includes a controller 610 and a temperature sensor 620. The controller 610 can be connected to a power source via an electrical connector 611, and the electrical connector 611 can be connected to a cigarette lighter plug when in the cab. In the present embodiment, two temperature sensors 620 are provided, which are symmetrically arranged on the upper surface of the thermal insulation pad 500 near both ends. The controller 610 is respectively connected to the temperature sensor 620 and the air supply control valve 300. The two temperature sensors 620 can detect the temperature of the upper surface of the thermal insulation pad 500 and transmit the data back to the controller 610. The controller 610 determines the temperature of the berth at this time according to the average value of the temperatures detected by the two temperature sensors 620, and compares this temperature with the preset temperature of the controller 610, thereby controlling the opening and closing of the air supply control valve 300 to ensure the constant temperature of the berth surface.

[0045] Of course, the number and location of the temperature sensors 620 can be adjusted according to actual conditions, and the preset temperature of the controller 610 can also be adjusted, which are not specifically limited herein.

[0046] That is to say, the berth body is composed of a bracket shell 100, an elastic support component 400 and a thermal insulation pad 500. In order to enable the berth to have the function of keeping warm and heating, an air supply duct 200 is laid inside the bracket shell 100. The air supply duct 200 is connected to an external air supply device such as an air conditioner or a diesel heater, and an air supply control valve 300 is provided at its inlet to control the amount of air supplied into the air supply duct 200, so as to control the temperature of the berth. In addition, in order to maintain a constant temperature of the berth, a temperature sensor 620 is provided on the surface of the thermal insulation pad 500. The temperature sensor 620 is connected to the controller 610, and the controller 610 can control the opening and closing of the air supply control valve 300 according to the temperature detected by the temperature sensor 620; in this way, the berth can be kept at a constant temperature, a suitable rest temperature can be provided for the driver, and it is safe and reliable under continuous working conditions.

[0047] In one embodiment, the air supply duct 200 can be set to a curved type, so that the air supply duct 200 can be bent and laid inside the bracket shell 100. Of course, in order to ensure that every position on the bunk bed can be heated, the air supply duct 200 needs to cover most of the space of the bracket shell 100. In addition, the air supply holes 210 on the air supply duct 200 can also be set as through holes with different aperture sizes.

[0048] In this embodiment, the elastic support assembly 400 is composed of a plurality of springs arranged in parallel, each of which is vertically attached to each other and spreads throughout the entire bracket housing 100. Since the axes of the springs are parallel to each other and perpendicular to the bottom surface of the bracket housing 100, as shown in FIG. Figure 2 and Figure 3 As shown, such an arrangement can greatly improve the comfort of the berth and increase the elasticity of the berth.

[0049] It can be understood that a breathable cover 700 is also provided between the elastic support assembly 400 and the thermal insulation pad 500. Figure 1 and Figure 3 As shown, in this embodiment, the thermal insulation pad 500 needs to ensure that the heat in the supporting shell will not be lost too quickly. Therefore, the thermal insulation pad 500 cannot have holes. However, the lower layer of the thermal insulation pad 500 is an elastic support assembly 400 composed of a plurality of springs. Therefore, in order to prevent the springs from squeezing and damaging the thermal insulation pad 500 when the berth is used for a long time, a breathable cover 700 is provided between the thermal insulation pad 500 and the elastic support assembly 400. The breathable cover 700 seals the entire berth as a whole and isolates the thermal insulation pad 500 and the elastic support assembly 400.

[0050] like Figure 1As shown, the air supply control valve 300 is fixedly installed inside the bracket shell 100 and close to the edge of the bracket shell 100, so that the air supply control valve 300 can be easily extended from the through hole opened on the inner wall of the bracket shell 100. The air supply control valve 300 will be connected to an external air supply device, such as an air conditioner or a diesel heater.

[0051] Of course, for the integrity and aesthetics of the constant temperature berth, the constant temperature berth also includes a skin assembly 800, which is coated on the outside of the bracket shell 100, the elastic support component 400 and the insulation pad 500, and the three form an integrated structure.

[0052] It can be understood that after hot air is introduced into the hot air bracket, the heat will easily escape from the gaps on its sides. Therefore, in this embodiment, the inner wall and bottom of the shell bracket shell 100 are laid with insulation cotton to prevent heat loss, and the thickness of the insulation cotton can be 5~10mm.

[0053] In this embodiment, the thermal insulation pad 500 is preferably a palm fiber pad, which is a breathable soft pad that can isolate hot air. It can store the heat of the berth while ensuring the overall comfort of the berth.

[0054] In this embodiment, after the temperature detected by the temperature sensor 620 is transmitted to the controller 610, the controller will compare the average temperature detected by all temperature sensors 620 with the preset temperature. When it is lower than the preset temperature, the air supply control valve 300 opens; when it is higher than the preset temperature, the air supply control valve 300 closes.

[0055] Of course, in order to prevent the air supply control valve 300 from being frequently opened or closed, thereby shortening its service life, the temperature range in which the air supply control valve 300 is opened or closed can be appropriately expanded. For example, when the temperature detected by the controller 610 is lower than the preset value by 2°, the air supply control valve 300 remains stationary. When the temperature is lower than the preset value by more than 2°, the air supply control valve 300 opens. Similarly, when the temperature detected by the controller 610 is higher than the preset value by more than 2°, the air supply control valve 300 remains stationary. When the temperature is higher than the preset value by more than 2°, the air supply control valve 300 is closed. That is, the air supply control valve 300 remains stationary when the temperature detected by the controller 610 is within the range of ±2° of the preset value, and the air supply control valve 300 is only controlled to be opened or closed when it exceeds the range.

[0056] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0057] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0058] The above is a detailed introduction to the embodiments provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
