Description

Technical Field

[0001] The present application relates to the technical field of power supply boxes, and in particular to a vehicle-mounted power supply box. Background Art

[0002] Multifunctional asphalt trucks are widely used in various scenarios such as asphalt paving, repair, and maintenance. The vehicles are usually equipped with the functions of mixing, conveying, and spraying asphalt, and also include some necessary auxiliary systems, such as heating systems and lighting systems. However, in complex and changing construction environments, multifunctional asphalt trucks often need to provide power support for various small electrical equipment, such as lighting fixtures, power tools, and environmental monitoring instruments. In order to facilitate the power supply to small electrical equipment and the control of other systems, the vehicle is equipped with a power box, which integrates the control circuit board, switches and sockets of various electrical components, and each electrical component is complex.

[0003] Since the socket is arranged inside the power box, the cover of the power box cannot be closed when in use. The working environment of the multi-functional asphalt truck is relatively harsh and the dust pollution is large. Dust entering the power box can easily cause damage to its internal components. If the socket is moved to the cover, although the power box can be closed when in use, the socket still needs to be waterproof and dustproof, which is inconvenient to use. Summary of the Invention

[0021] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0022] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

[0025] See also Figure 1-Figure 3 A vehicle-mounted power box includes a power box body 1 and a box cover 2 arranged on the power box body 1. The control circuit board, switches of various electrical components, sockets, etc. are all installed in the power box body 1, and the sockets are installed on the horizontal center line of the power box body 1.

[0026] The box cover 2 is provided with a connection window 3, which is positioned directly opposite the socket location and along the horizontal centerline of the box cover 2. A worker can plug a lighting fixture, power tool, environmental monitoring instrument, etc. into the socket within the power box through the connection window 3 to extract power. Sealing structures are symmetrically mounted on the upper and lower sides of the connection window 3 to seal the connection window 3, thereby completely enclosing the power box and preventing dust, moisture, etc. from entering the power box, which could cause technical problems such as component short circuits and poor contact.

[0027] The sealing structure includes a sealing sheet 4, a connecting rope 5, and a pull plate 6; the sealing sheets 4 are tightly arranged along the length direction of the connecting window hole 3 so that a seal is formed between adjacent sealing sheets 4, and are respectively slidably connected to the box cover 2 so that the sealing sheets 4 can move up and down and can extend into the connecting window hole 3. When the sealing sheets 4 on the upper and lower sides are extended into the connecting window hole 3 to the limit distance, the ends of the two abut against each other, thereby completely closing the connecting window hole 3.

[0028] The pull plate 6 is disposed above the sealing sheet 4 and is slidably connected to the box cover 2 to enable its up and down movement. The pull plate 6 is connected to each sealing sheet 4 via a connecting rope 5 to limit the maximum distance that each sealing sheet 4 can extend into the connecting window 3, thereby preventing the sealing sheet 4 from separating from the box cover 2. A driving medium is provided between the pull plate 6 and the sealing sheet 4 for driving the sealing sheet 4 to move into the connecting window 3.

[0029] When not in use, the box cover 2 is closed, and the sealing piece 4 extends into the connecting window hole 3 to the limit distance under the action of the driving medium. The ends of the sealing piece 4 on the upper and lower sides abut against each other, thereby closing the connecting window hole 3, thereby achieving the purpose of closing the power box.

[0030] When the socket needs to be used, pull the pull plate 6 on the upper side upwards, and drive all the sealing plates 4 on the upper side to move upwards through the connecting rope 5; pull the pull plate 6 on the lower side downwards, and drive all the sealing plates 4 on the lower side to move downwards through the connecting rope 5; then open the connecting window 3, so that the staff can connect the corresponding plug to the socket through the connecting window 3; then reset the pull plates 6 on the upper and lower sides respectively, and each sealing plate 4 moves toward the connecting window 3 to the limit distance under the action of the driving medium, wherein some ends of the sealing plates 4 on the upper and lower sides abut against each other to form a seal, and some ends of the sealing plates 4 abut against the power cord of the plug to form a seal, thereby realizing the overall sealing of the connecting window 3, avoiding the technical problem of dust, water vapor, etc. entering the power box, and there is no need to open the box cover 2 during the use of the socket, which is convenient to use.

[0031] In some embodiments, Figure 3 As shown, the driving medium adopts high-pressure air, and sealing sheets 4 are respectively provided between the pull plate 6 and the box cover 2, and between the sealing sheet 4 and the box cover 2, so as to achieve sealing between the pull plate 6 and the box cover 2, and sealing between the sealing sheet 4 and the box cover 2 to avoid the problem of air leakage. At the same time, by providing the sealing sheet 4, the friction between the pull plate 6 and the box cover 2 is increased, and the pull plate 6 is not easy to move after being pushed to the corresponding position, especially the pull plate 6 located at the bottom will not shift downward under the action of gravity.

[0032] In some embodiments, such as Figure 2As shown, the driving medium uses a spring 7. Compared with using high-pressure air as the driving medium, the driving method is more stable and less prone to errors.

[0033] In some embodiments, such as Figure 1 As shown, a limit block 8 is provided on the pull plate 6 located below, and a hook 9 capable of hooking the limit block 8 is provided on the box cover 2. The root of the hook 9 is hinged to the box cover 2, and the end of the hook 9 is in a hook shape. The position of the pull plate 6 located below is limited by the hook 9, which effectively prevents the pull plate 6 located below from shifting downward due to vibration when the asphalt truck is working, and the pull plate 6 located above automatically falls to a predetermined position by gravity.

[0034] In some specific embodiments, the pull plate 6 is provided with a handle 10 protruding from the box cover 2 to facilitate the movement of the pull plate 6 .

[0035] In some specific embodiments, a flexible section 41 is provided at one end of the sealing sheet 4 extending into the connecting window hole 3. The flexible section 41 is made of plastic material, such as plastic foam, rubber, etc. When the sealing sheet 4 contacts the power cord, it deforms, so that the sealing sheet 4 can better wrap the corresponding wire and improve the sealing effect.

[0036] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
