DETAILED DESCRIPTION

[0023] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0024] Please refer to Figure 1 and Figure 2 , now a truck bunk with heating and ventilation functions provided by the utility model will be described. The truck bunk with heating and ventilation functions comprises a bunk box body 1, a bunk pad 2 and a pipeline 3. The inside of the bunk box body 1 is provided with a heating cavity 101, the lower part of the heating cavity 101 is provided with a first ventilation duct 102, the first ventilation duct 102 is arranged along the horizontal direction, a plurality of second ventilation ducts 103 are arranged between the first ventilation duct 102 and the heating cavity 101, and the plurality of second ventilation ducts 103 are evenly arranged along the length direction of the first ventilation duct 102; the bunk pad 2 is arranged on the top of the bunk box body 1; one end of the pipeline 3 is connected with the first ventilation duct 102, and the other end is connected with the air outlet of a parking heater 4.

[0025] Compared with the prior art, the high-temperature gas generated by the parking heater 4 passes through the pipeline 3, the first ventilation duct 102 and the second ventilation duct 103 in sequence and finally enters the heating cavity 101, so that the bunk pad 2 is heated through heat exchange, so that the person on the bunk is warmer when resting on the bunk box, and the comfort of the person on the bunk when resting is improved. Since the plurality of second ventilation ducts 103 are evenly arranged along the length direction of the first ventilation duct 102, the high-temperature air can be uniformly delivered into the heating cavity 101, so that the bunk pad 2 is heated more uniformly.

[0026] The parking heater 4 is a vehicle-mounted heating device independent of the automobile engine. The purposes of the parking heater 4 include providing a heat source for low-temperature starting of various vehicle engines, defrosting of the windshield glass and heating of the vehicle cabin.

[0027] In some examples, please refer to Figure 1A sealing ring 104 is arranged between the pipeline 3 and the sleeper box body 1. In this embodiment, the sealing ring 104 is a rubber ring. The sealing ring 104 is arranged between the outer wall of the pipeline 3 and the inner wall of the first ventilation duct 102. The sealing ring 104 is used to improve the sealing between the pipeline 3 and the sleeper box body 1, so as to avoid heat loss caused by air leakage.

[0028] In some embodiments, referring to Figure 1 The first ventilation duct 102 penetrates the sleeper box body 1, and a plug 105 is arranged at the end of the first ventilation duct 102 away from the pipeline 3. In this embodiment, the first ventilation duct 102 is a through hole penetrating the entire sleeper box body 1. The pipeline 3 and the plug 105 are arranged at two ends of the first ventilation duct 102, respectively. The plug 105 is detachably arranged in the first ventilation duct 102. When the first ventilation duct 102 needs to be cleaned, the plug 105 can be removed.

[0029] In some embodiments, the plug 105 is connected to the sleeper box body 1 by threads. In this embodiment, the plug 105 is a cylindrical plug, and an outer thread matched with the first ventilation duct 102 is arranged on the outer circumference of the plug 105. The plug 105 is connected to the sleeper box body 1 by threads, which is simple in structure and facilitates the disassembly and assembly of the plug 105.

[0030] In some embodiments, referring to Figure 1 A blocking rod 106 is rotatably arranged on the sleeper box body 1, the rotation axis of the blocking rod 106 is perpendicular to the second ventilation duct 103, and a communication hole 107 corresponding to the second ventilation duct 103 is arranged on the blocking rod 106. In this embodiment, the blocking rod 106 is a cylindrical rod. The second ventilation duct 103 is arranged in the vertical direction. The blocking rod 106 is arranged on the sleeper box body 1 in the horizontal direction. The blocking rod 106 can rotate around its own axis. The blocking rod 106 penetrates the second ventilation duct 103. The diameter of the communication hole 107 is greater than or equal to the diameter of the second ventilation duct 103. The opening and closing of the second ventilation duct 103 can be realized by rotating the blocking rod 106.

[0031] In some embodiments, referring to Figure 1 , Figure 3 and Figure 4 A filter screen 108 is arranged in the communication hole 107. In this embodiment, in order to prevent dust in the high-temperature gas from entering the heating cavity 101, the filter screen 108 is arranged in the communication hole 107. Two elastic force arms 113 are symmetrically arranged on the top of the filter screen 108, a clamping plate 114 is arranged at the top end of each elastic force arm 113, and a clamping groove 115 matched with the clamping plate 114 is arranged on the inner wall of the communication hole 107. The filter screen 108 is fixed in the second ventilation duct 103 by the clamping plates 114 on the two elastic force arms 113.

[0032] In some embodiments, referring to Figure 1 A bearing 109 is installed between the baffle rod 106 and the sleeper box body 1. In the embodiment, the bearing 109 can reduce the frictional resistance between the baffle rod 106 and the sleeper box body 1, thereby reducing the labor intensity of the operator when driving the baffle rod 106 to rotate.

[0033] In some embodiments, referring to Figure 1 A handle 110 is installed at one end of the baffle rod 106. In the embodiment, the handle 110 is disc-shaped and is welded and fixed at one end in the length direction of the baffle rod 106. By providing the handle 110 on the baffle rod 106, the operator can conveniently drive the baffle rod 106 to rotate.

[0034] In some embodiments, referring to Figure 1 The handle 110 is located on the inner side of the sleeper box body 1, and a clearance groove 116 for avoiding the handle 110 is formed on the side wall of the sleeper box body 1. In the embodiment, by forming the clearance groove 116 on the side wall of the sleeper box body 1, the handle 110 is completely located on the inner side of the sleeper box body 1, so that the structure is more compact and the handle 110 cannot be bumped.

[0035] In some embodiments, referring to Figure 1 The top of the heating cavity 101 is of an open structure, and the sleeper pad 2 is located at the top opening of the heating cavity 101. In the embodiment, since the sleeper pad 2 is located at the top opening of the heating cavity 101, the sleeper pad 2 can directly contact the high-temperature gas in the heating cavity 101, thereby improving the heating efficiency of the sleeper pad 2. A flexible support strip 111 is further installed on the sleeper box body 1, and the flexible support strip 111 is located at the bottom of the sleeper pad 2 and provides a supporting force to the sleeper pad 2. A compression spring 112 is further installed in the heating cavity 101 and is located between two adjacent second ventilation ducts 103. The compression spring 112 is installed below the flexible support strip 111 and provides a supporting force to the flexible support strip 111. Since the flexible support strip 111 and the compression spring 112 both have elasticity, the comfort of the sleeper box can be improved.

[0036] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
