[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0030] Railway transportation has the characteristics of large transportation volume, fast transportation speed and low transportation cost. Therefore, railway transportation is currently the main force of coal energy transportation.

[0031] When transporting coal in low-temperature environments, coal trucks can freeze and stick to the truck's body panels due to the high moisture content of the coal. Currently, coal stuck to the panels is typically removed manually, such as by hammering or scraping with a pickaxe. However, manual cleaning is labor-intensive, inefficient, and can cause significant damage to the vehicle.

[0032] Based on the above technical problems, an embodiment of the present application discloses a truck body, on which a heating module is integrated. The heating module is used to heat the truck body, thereby separating the material frozen on the truck body from the truck body.

[0033] like Figure 1 As shown, the body of the truck according to the embodiment of the present application includes: side walls 100 , end walls 200 , a bottom frame 300 and a heating module 400 .

[0034] The side walls 100 extend along a first direction, the end walls 200 extend along a second direction, and both the side walls 100 and the end walls 200 are disposed on a base frame 300. The first direction and the second direction are two intersecting directions. Optionally, the first direction and the second direction are perpendicular to each other, and both the first direction and the second direction are parallel to the plane of the base frame 300. Optionally, the third direction herein is a direction perpendicular to the base frame 300.

[0035] In some embodiments, there are two side walls 100 and two end walls 200. The two side walls 100 are arranged opposite each other along the second direction, and the two end walls 200 are arranged opposite each other along the first direction. The side walls 100 and end walls 200 are arranged opposite each other and are fixedly connected in sequence to form a closed structure. The side walls 100, end walls 200, and chassis 300 enclose a storage space within the truck body, which is used to store cargo transported by the truck. It should be noted that the side walls 100 and end walls 200 herein are sequentially connected to form the side panels of the truck body.

[0036] The side walls 100 , the end walls 200 and the bottom frame 300 may be connected by welding or threaded connections, and the connection method between the side walls 100 , the end walls 200 and the bottom frame 300 is not limited thereto.

[0037] In the embodiment of the present application, at least one of the side wall 100 and the end wall 200 has a heating module 400 , and the heating module 400 is used to heat the vehicle body.

[0038] During de-icing or material removal of a truck using this vehicle body, the vehicle body can be heated by the heating module 400 to quickly thaw the frozen coal on the inner surface of the vehicle body. This method does not require manual cleaning, thereby reducing the labor intensity of manual coal cleaning operations, improving cleaning efficiency, and reducing damage to the vehicle.

[0039] In some embodiments, the heating module 400 is embedded within at least one of the sidewall 100 and the end wall 200. The embedded arrangement of the heating module 400 allows the sidewall 100 and the end wall 200 to protect the heating module 400 and prevent damage to the heating module 400 by materials within the accommodating space.

[0040] In some other embodiments, the heating module 400 may be attached to a surface of at least one of the side wall 100 and the end wall 200. The attachment of the heating module 400 can simplify the installation of the heating module 400 and facilitate the assembly and disassembly of the heating module 400.

[0041] like Figure 2 and Figure 3 As shown, the heating module 400 disclosed in the embodiment of the present application is a layered plate structure. The following description will be made by taking the example of the heating module 400 being embedded in at least one of the side wall 100 and the end wall 200 .

[0042] The heating module 400 includes a heating layer 401 , a grounding layer 402 , a heat insulating layer 403 and a mounting base layer 404 .

[0043] The mounting base layer 404 has a certain strength and toughness, serving as a mounting base for the heating module 400. The mounting base layer 404 also serves as a base for connecting the heating module 400 to the side panels. The heating layer 401 is a structure capable of generating heat, and the thermal insulation layer 403 provides a thermal insulation effect to hinder heat transfer from the heating layer 401. Optionally, the thermal insulation layer 403 is installed between the mounting base layer 404 and the heating layer 401.

[0044] In some embodiments, the heat insulating layer 403 is laminated on the mounting base layer 404, and the heat generating layer 401 is laminated on the heat insulating layer 403. Optionally, after laminating, the layers can be pressed together into an integral structure using a press and adhesive.

[0045] The present application embodiment discloses two structures of the heating layer 401. Figure 4 and Figure 5 The structure of the heating layer 401 is described below. However, the structure of the heating layer 401 is not limited to the structure described below. Other structures that can achieve heating are within the scope of protection.

[0046] like Figure 4 As shown, the heating layer 401 of the embodiment of the present application includes: a mounting film 4011 and a carbon fiber heating cable 4012 .

[0047] Carbon fiber heating cable 4012 comprises, from the outside in, a high-temperature resistant layer, a waterproof layer, an acid- and alkali-resistant layer, and a carbon fiber cable. Carbon fiber heating cable 4012 uses metal heating elements as its heating material. The heating principle is that when electricity is applied to the metal conductor, it generates heat due to its own electrical resistance, which is then dissipated through heat conduction.

[0048] The carbon fiber heating cable 4012 is bent and coiled back and forth on the mounting film 4011. Optionally, the carbon fiber heating cable 4012 is arranged in a serpentine shape. The density of the carbon fiber heating cable 4012 on the mounting film 4011 can be adjusted according to the heating power requirement.

[0049] The mounting film 4011 of this embodiment serves as the mounting base for the carbon fiber heating cable 4012 and can be, but is not limited to, a plastic film. In some embodiments, the mounting film 4011 can be eliminated and directly mounted on the insulation layer 403 or the grounding layer 402 to simplify the structure and reduce costs.

[0050] During the heating process of the heating layer 401, power can be supplied to the carbon fiber heating cable 4012, causing the carbon fiber heating cable 4012 to generate heat. The coiled carbon fiber heating cable 4012 can increase the heating area, ensuring the heating effect of the heating layer 401. It should be noted that carbon fiber material has the characteristics of high conductivity and strength, rapid heating, strong far-infrared radiation, and high electric-to-heat conversion efficiency. Therefore, the carbon fiber heating cable 4012 can heat the vehicle body more quickly.

[0051] like Figure 5 As shown, the heating layer 401 of the embodiment of the present application includes: a carbon fiber film 4013 and a conductive tape 4014.

[0052] The carbon fiber film 4013 has strong electrical conductivity, generates heat quickly, and has a high electrothermal conversion rate. Therefore, the carbon fiber film 4013 can quickly diffuse heat. In addition, the carbon fiber film 4013 has high strength, which can help ensure the strength requirements of the heating layer 401.

[0053] In some embodiments, the carbon fiber membrane 4013 is a carbon fiber film with a thickness of 1 mm to 2 mm. The thickness and size of the carbon fiber membrane 4013 can be set differently and are all within the protection range.

[0054] In the embodiment of the present application, a conductive tape 4014 is provided on the carbon fiber film 4013. The conductive tape 4014 may be a copper tape or other conductive material. The conductive tape 4014 is electrically connected to a power supply device, which supplies power to the conductive tape 4014. The heat generated by the conductive tape 4014 is diffused throughout the carbon fiber film 4013, thereby generating heat for the heating layer 401.

[0055] The embodiments of the present application show two different structures of the heating layer 401. In some other embodiments, the heating layer 401 may also adopt other forms of heating layer 401, for example, electromagnetic heating or resistance heating.

[0056] Since the heating layer 401 is electrically connected to the power supply equipment, current passes through the heating layer 401 during operation. In order to prevent leakage caused by damage to the heating layer 401 from affecting personal safety, a grounding layer 402 is provided between the heating layer 401 and the insulation layer 403 in the embodiment of the present application.

[0057] The grounding layer 402 is a conductor and is attached to the heating layer 401 , or the heating layer 401 is disposed on the surface of the grounding layer 402 ; the grounding layer 402 is connected to a grounding device to achieve equipotential between the grounding layer 402 and the ground.

[0058] The heating layer 401 of the embodiment of the present application can capture leakage electricity generated by perforation of the carbon fiber heating cable 4012 or the carbon fiber film 4013, thereby reducing the risk of electric shock to the human body.

[0059] Optionally, ground layer 402 is made of flexible aluminum foil. Using aluminum foil for ground layer 402 in this embodiment of the present application can reduce the cost of ground layer 402 and effectively capture leakage current. Of course, ground layer 402 in this embodiment of the present application can also be made of other conductive materials, all of which are within the scope of protection.

[0060] The heat insulating layer 403 of the embodiment of the present application has a heat insulating and heat-preserving function, preventing the heat generated by the heating layer 401 from diffusing toward the side panel of the vehicle body away from the accommodating space, thereby reducing energy waste and increasing the heat radiated by the heating layer 401 to the accommodating space.

[0061] Optionally, the heat insulating layer 403 may be made of an elastic foam material. Of course, the heat insulating layer 403 may also be made of an aerogel material.

[0062] It should be noted that the heating module 400 is not limited to the heating module 400 disclosed in the above embodiment. In some other embodiments, the heating module 400 may also adopt other structures. For example, a circulation channel is set inside at least one of the side wall 100 and the end wall 200, and hot air or high-temperature liquid is injected into the circulation channel to achieve heating of the vehicle body.

[0063] In the scenario where the heating module 400 of the above embodiment is applied to a vehicle body, the heating module 400 is embedded in the vehicle body. In some embodiments, the side wall 100 and the end wall 200 can both be hollow profiles with a hollow cavity to facilitate the embedded arrangement of the heating module 400. Figures 6 to 8The structures of the side wall 100 and the end wall 200 are described respectively, and the manner in which the heating module 400 is arranged in the hollow profile is described.

[0064] like Figure 6 As shown, the side wall 100 includes: a first hollow profile 101 .

[0065] The first hollow profile 101 has a first hollow cavity. It is understood that the first hollow profile 101 is a hollow structure, and the hollow structure of the first hollow profile 101 forms the first hollow cavity. Optionally, the first hollow cavity of the first hollow profile 101 extends along a first direction, and the heating module 400 is disposed in the first hollow cavity, so that the heating module 400 is embedded in the side wall 100.

[0066] In some embodiments, the first hollow profile 101 is a hollow profile obtained by an extrusion process. The first hollow profile 101 is formed by extrusion, which can ensure the strength of the first hollow profile 101, reduce the number of connection points of the first hollow profile 101, and improve the processing efficiency of the first hollow profile.

[0067] The side wall 100 is provided with a plurality of first hollow profiles 101 along the third direction, and adjacent first hollow profiles 101 are fixedly connected.

[0068] In the embodiment of the present application, the side wall 100 is arranged with multiple first hollow profiles 101 along the third direction, thereby increasing the area of ​​the side wall 100. This can be understood as the side wall 100 being divided into multiple first hollow profiles 101 connected together. By dividing the side wall 100 into multiple first hollow profiles 101, the smaller first hollow profiles 101 have greater strength, thereby increasing the overall strength of the side wall 100.

[0069] In the scenario where there are multiple first hollow profiles 101, there may be multiple heating modules 400 in the present application. Optionally, the heating modules 400 are arranged in a one-to-one correspondence with the first hollow profiles 101, that is, a heating module 400 is provided in each first hollow profile 101. Optionally, these heating modules 400 are arranged in parallel through cables and electrically connected to a power supply device so that the heating modules 400 are powered by the power supply device.

[0070] The size of the first hollow profile 101 along the first direction, the size along the second direction, and the size along the third direction can be set according to different needs and are not specifically limited here.

[0071] In some embodiments, the adjacent first hollow profiles 101 arranged along the third direction can be connected by welding or by threaded connectors. The connection method of adjacent first hollow profiles 101 is not limited to the above connection methods.

[0072] like Figure 7As shown, the heating module 400 is arranged in the scenario of the first hollow cavity of the first hollow profile 101, and the heating layer 401 of the heating module 400 is arranged toward the side wall of the first hollow cavity close to the accommodating space. The heating layer 401 is arranged toward the accommodating space, and the heat generated by the heating layer 401 is used to heat the side of the first hollow profile 101 close to the accommodating space; the installation base layer 404 of the heating module 400 is connected to the side wall of the first hollow cavity away from the accommodating space. Optionally, the installation base layer 404 is bonded or clamped to the side wall of the first hollow cavity away from the accommodating space.

[0073] like Figure 8 As shown, the end wall 200 includes: a second hollow profile 201 and a support plate 202 .

[0074] The second hollow profile 201 is arranged perpendicular or obliquely to the chassis 300. The relationship between the second hollow profile 201 and the chassis 300 can be customized based on the truck's requirements. The second hollow profile 201 is arranged perpendicular to the chassis 300 to increase the volume of the storage space. The second hollow profile 201 is arranged obliquely to the chassis 300. With the support plate 202, the end wall 200 is arranged in a herringbone pattern, which improves its strength.

[0075] The second hollow profile 201 has a second hollow cavity, which extends along the arrangement direction of the second hollow profile 201 , ie, the second hollow cavity extends in a direction inclined to the base frame 300 . The heating module 400 is disposed in the second hollow cavity of the second hollow profile 201 .

[0076] In the scenario where the heating module 400 is arranged in the second hollow cavity of the second hollow profile 201, the heating layer 401 of the heating module 400 is arranged toward the side wall of the second hollow cavity close to the accommodating space, and the heating layer 401 is arranged toward the accommodating space, and the heat generated by the heating layer 401 is used to heat the side of the second hollow profile 201 close to the accommodating space; the installation base layer 404 of the heating module 400 is connected to the side wall of the second hollow cavity away from the accommodating space, and optionally, the installation base layer 404 is bonded or clamped to the side wall of the second hollow cavity away from the accommodating space.

[0077] It should be noted that the first hollow profile 101 and the second hollow profile 201 of the embodiment of the present application adopt a hollow aluminum profile body. The hollow structure helps to reduce the heat conduction of coal to a certain extent and has a certain effect on the thermal insulation of the truck.

[0078] In the embodiment of the present application, the cross-sectional width of the first hollow profile 101 and the second hollow profile 201 may be 40 mm to 70 mm, and the wall thickness of the profile may be 2 mm to 5 mm.

[0079] In some embodiments, the end wall 200 has a plurality of second hollow profiles 201, each of which is provided with a heating module 400. Optionally, the heating modules 400 are arranged in parallel via cables and electrically connected to a power supply device to supply power to the heating modules 400.

[0080] The support plate 202 is located outside the accommodating space, and the first end of the support plate 202 is connected to the second hollow profile 201, and the second end of the support plate 202 is fixedly connected to the base frame 300. The support plate 202 is arranged at an angle to the base frame 300, and the inclination direction of the support plate 202 relative to the base frame 300 is opposite to the inclination direction of the second hollow profile 201 relative to the base frame 300.

[0081] For example, the end of the second hollow profile 201, which extends away from the base frame 300, is tilted away from the accommodating space relative to the end of the second hollow profile 201, which extends closer to the base frame 300. The first end of the support plate 202 is tilted toward the accommodating space relative to the second end. The tilted second hollow profile 201 and the tilted support plate 202, connected to the base frame 300, form a stable triangular structure, which helps to improve the strength of the end wall 200.

[0082] The shape and size of the support plate 202 can be set according to different needs and are all within the protection range. Optionally, the first end of the support plate 202 is fixedly connected to the middle position of the second hollow profile 201 along the extension direction.

[0083] The connection between the support plate 202 and the second hollow profile 201 , and between the support plate 202 and the base frame 300 may be, but is not limited to, welding or threaded connection.

[0084] In some other embodiments, the vehicle body further includes: a detection device and a control system.

[0085] The detection device is disposed on at least one of the side wall 100 and the end wall 200 , and is configured to detect the temperature of the side panel.

[0086] Optionally, the detection device can be a temperature sensor. Temperature sensors can be provided on both the side wall 100 and the end wall 200 of the vehicle body. For example, the temperature sensors are provided on the side of the side wall 100 and the end wall 200 close to the accommodation space. The temperature sensors can be used to detect the temperature of the side wall 100 and the end wall 200 of the vehicle body. Based on the temperature detected by the temperature sensors, it can be determined whether the vehicle body needs to be heated.

[0087] The control system is connected to the detection device, and the control system is also connected to the heating module 400. The detection device transmits the acquired temperature information to the control system, and the control system adjusts the power of the heating module 400 according to the acquired temperature information.

[0088] For example, the detection device transmits the detected temperature information to the control system, and the control system determines the size of the temperature value corresponding to the acquired temperature information and the preset temperature value based on the acquired temperature information. If the control system determines that the temperature value corresponding to the acquired temperature information is not greater than the preset temperature value, the control system controls the heating module 400 to start.

[0089] If the control system determines that the temperature value corresponding to the acquired temperature information is not greater than the preset temperature value within the preset time, the control system increases the power of the heating module 400 .

[0090] The preset temperature of the embodiment of the present application can be set according to different needs, for example, the preset temperature can be 3° C. The preset time can be set according to different needs, for example, the preset time can be 30 minutes.

[0091] In addition, an embodiment of the present application also discloses a truck, including a vehicle body, wherein the vehicle body is the vehicle body disclosed in the above embodiment. Therefore, the truck with this vehicle body also has all the above technical effects, which will not be repeated.
