Description

Technical Field

[0001] This utility model relates to the field of charging display equipment technology, and specifically to a charging display device for engineering machinery. Background Technology

[0002] With the development of the construction machinery industry and the promotion of new energy sources, some construction machinery is now adopting electric drive. Battery charging status is a crucial parameter for electrically driven construction machinery. Patent number CN202021855226.7 discloses a battery charging status monitoring and display device for construction machinery. This device effectively monitors battery charging status and displays charging status information externally on the machine using indicator lights. It is stable, reliable, and easy to understand, allowing the driver to observe the battery charging status in real time from outside the cab. However, in the use of charging display devices for construction machinery, relying solely on indicator lights to display the charging status is somewhat limited, as personnel cannot clearly understand the charging progress. Therefore, we propose a charging display device for construction machinery. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a charging display device for engineering machinery.

[0004] The technical solution adopted by this utility model to solve its technical problem is a charging display device for engineering machinery, including a plate base, a charging base for charging engineering machinery is assembled on the outer wall surface of the plate base, and a shell base for support is assembled on the outer wall surface of the plate base, a display screen for charging display is assembled on the outer wall surface of the shell base, and an indicator light for charging status display is assembled on the outer wall surface of the shell base, and there are multiple sets of indicator lights.

[0005] The outer wall surface of the plate base is integrally constructed with a protective shell, and the outer wall surface of the shell is fitted with a cover plate for sealing. The outer wall surface of the cover plate is fitted with a plug for conducting electricity, and one end of the plug located inside the shell is slidably installed with a power connector that fits into the charging base. An electric push rod is installed inside the shell, and the power output end of the electric push rod is fitted with a U-shaped shovel plate that abuts against the power connector. A spring for pushing the power connector to move is fitted between the cover plate and the power connector.

[0006] By adopting the above technical solution, when using the charging display device for construction machinery, the indicator light on the housing surface of the base can be used to observe the charging status. At the same time, the display screen on the housing surface can conveniently display the power of the battery inside the construction machinery during charging, so that personnel can clearly understand how much is being charged, thereby controlling the charging time and improving the convenience of using the mechanical charging display device.

[0007] After the construction machinery is fully charged, the display screen can control the operation of the electric push rod inside the housing. The operation of the electric push rod facilitates the displacement of the U-shaped shovel, allowing the inclined surface of the U-shaped shovel to be inserted between the power connector and the charging base. This allows the power connector and the charging base to be separated from each other, thus directly and physically disconnecting the charging contact point. This facilitates the protection of the battery inside the construction machinery and helps reduce the impact of continuous battery charging.

[0008] Specifically, the plate base is equipped with a trapezoidal plate that abuts against the U-shaped shovel plate at one end inside the housing.

[0009] By adopting the above technical solution, the trapezoidal plate can easily provide auxiliary support for the U-shaped shovel plate, enabling the U-shaped shovel plate to operate more stably.

[0010] Specifically, the outer wall surface of the housing is equipped with buttons for operation, and there are two sets of buttons.

[0011] By adopting the above technical solution, during charging, pressing a set of buttons on the surface of the housing enables the display screen to operate and show the battery level during charging. Another set of buttons facilitates the operation of the electric push rod inside the housing, allowing the U-shaped shovel plate to separate from the power connector and charging base. Then, the spring inside the cover plate pushes the power connector, causing the power connector sliding on the outer periphery of the plug to move and engage with the charging base, allowing the circuit to flow. Subsequently, the charging port of the charging base on the outside of the housing can be easily connected to the charging circuit, facilitating the charging of construction machinery.

[0012] Specifically, the plate base is equipped with a bottom ring located on the outer periphery of the charging base at one end inside the housing, and a straight rod is installed between the bottom ring and the plug to be connected to the charging base, and there are multiple sets of straight rods.

[0013] By adopting the above technical solution, the bottom ring is located on the outer periphery of one end of the charging base inside the housing, which facilitates the support of the straight rod. The straight rod can be easily inserted and slidably connected with the charging base, which improves the stability of the charging base when it is moved, thereby reducing the misalignment between the charging base and the charging base.

[0014] Specifically, a protective rubber pad is adhered to the side of the power connector near the base.

[0015] By adopting the above technical solution, the rubber pad has a certain degree of elasticity, which helps to reduce the friction and scratches caused when the junction box and the bottom ring come into contact with each other, and facilitates buffer protection for the junction box.

[0016] Specifically, the outer wall surface of the U-shaped shovel plate is integrally constructed with an annular cylinder located around the electric push rod, and the inner wall surface of the housing is fitted with an annular shell that fits the annular cylinder.

[0017] By adopting the above technical solution, the ring shell and the ring cylinder fit together and slide together, which facilitates the improvement of the stability of the U-shaped shovel plate during displacement, and enables the U-shaped shovel plate to more stably connect with the electric base and the charging base for separation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The technical solution of this application, through the design of a charging base, housing, display screen and indicator lights, allows the charging status to be observed using the indicator lights on the housing surface when using the charging display device for construction machinery. At the same time, the display screen on the housing surface conveniently displays the power of the battery inside the construction machinery during charging, making it easy for personnel to clearly understand the amount of charging, thereby controlling the charging time and improving the convenience of using the mechanical charging display device.

[0020] 2. The technical solution of this application, through the design of the housing, cover plate, plug, power socket, electric push rod, U-shaped shovel plate and spring, allows the display screen to control the operation of the electric push rod inside the housing after the construction machinery is charged. The operation of the electric push rod facilitates the displacement of the U-shaped shovel plate, so that the inclined surface of the U-shaped shovel plate can be inserted between the power socket and the charging socket, allowing the power socket to be separated from the charging socket, thereby directly and physically disconnecting the charging contact point, which is convenient for protecting the battery inside the construction machinery and reducing the impact caused by continuous charging of the battery.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a charging display device for engineering machinery, including a base 1, a charging base 2 for charging the engineering machinery is mounted on the outer wall surface of the base 1, a supporting shell 3 is mounted on the outer wall surface of the base 1, a display screen 4 for charging display is mounted on the outer wall surface of the shell 3, and multiple indicator lights 5 for charging status display are mounted on the outer wall surface of the shell 3; a protective shell 6 is integrally constructed on the outer wall surface of the base 1, and a sealing cover 7 is mounted on the outer wall surface of the shell 6; a conductive plug 8 is mounted on the outer wall surface of the cover 7, and a power connector 9 that fits with the charging base 2 is slidably installed at one end of the plug 8 inside the shell 6; an electric push rod 10 is mounted inside the shell 6, and a U-shaped shovel 11 that abuts against the power connector 9 is mounted at the power output end of the electric push rod 10; a spring 12 for pushing the power connector 9 to move is mounted between the cover 7 and the power connector 9.

[0028] When using the charging display device for construction machinery, the indicator light 5 on the housing 3 on the surface of the base 1 can be used to observe the charging status. At the same time, the display screen 4 on the surface of the housing 3 can conveniently display the power of the battery inside the construction machinery during charging, so that the personnel can clearly understand how much is being charged, thereby controlling the charging time and improving the convenience of using the mechanical charging display device.

[0029] After the construction machinery is fully charged, the display screen 4 can control the operation of the electric push rod 10 inside the housing 6. The operation of the electric push rod 10 facilitates the displacement of the U-shaped shovel 11, so that the inclined surface of the U-shaped shovel 11 can be inserted between the power connector 9 and the charging base 2, allowing the power connector 9 to be separated from the charging base 2, thereby directly and physically disconnecting the charging contact point. This facilitates the protection of the battery inside the construction machinery and reduces the impact of continuous charging of the battery.

[0030] like Figure 2 As shown, the plate base 1 is fitted with a trapezoidal plate 13 that abuts against the U-shaped shovel plate 11 at one end inside the housing 6.

[0031] When in use, the trapezoidal plate 13 provides auxiliary support for the U-shaped shovel plate 11, enabling the U-shaped shovel plate 11 to operate more stably.

[0032] like Figure 1 As shown, the outer wall surface of the housing 3 is fitted with buttons 19 for operation, and there are two sets of buttons 19.

[0033] During use, when charging, pressing a set of buttons 19 on the surface of the housing 3 will activate the display screen 4 and display the battery level during charging. Another set of buttons 19 will allow control of the electric push rod 10 inside the housing 3, enabling the U-shaped shovel plate 11 to separate from the power connector 9 and the charging base 2. Then, the spring 12 inside the cover plate 7 will push the power connector 9, causing the power connector 9, which slides around the plug 8, to move and engage with the charging base 2, allowing the circuit to flow. Subsequently, the charging port of the charging base 2 on the outside of the base 1 can be easily connected to the charging circuit, facilitating the charging of construction machinery.

[0034] like Figure 2 and Figure 3 As shown, the plate base 1 is fitted with a bottom ring 17 located on the outer periphery of the charging base 2 at one end inside the housing 6, and a straight rod 18 that is connected to the charging base 9 is fitted between the bottom ring 17 and the plug 8, and there are multiple sets of straight rods 18.

[0035] During use, the bottom ring 17 is located on the outer periphery of one end of the charging base 2 inside the housing 6, which facilitates the support of the straight rod 18. The straight rod 18 can be easily inserted and slidably connected with the power connector 9, which improves the stability of the power connector 9 when it is displaced, thereby reducing the misalignment between the power connector 9 and the charging base 2.

[0036] like Figure 2 As shown, a protective rubber pad 16 is adhered to the side of the electrical connector 9 near the base plate 1.

[0037] When in use, the rubber pad 16 has a certain degree of elasticity, which helps to reduce the friction between the connector 9 and the bottom ring 17 and prevent scratches, thus providing buffer protection for the connector 9.

[0038] like Figure 2 and Figure 3 As shown, the outer wall surface of the U-shaped shovel plate 11 is integrally constructed with an annular cylinder 14 located around the electric push rod 10, and the inner wall surface of the housing 6 is fitted with an annular shell 15 that fits with the annular cylinder 14.

[0039] During use, the ring shell 15 and the ring cylinder 14 fit together and slide together, which helps to improve the stability of the U-shaped shovel plate 11 during displacement, and allows the U-shaped shovel plate 11 to more stably connect with the electric base 9 and the charging base 2 for separation.

[0040] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. When using the charging display device for construction machinery, the indicator light 5 on the housing 3 of the base 1 can be used to observe the charging status. Simultaneously, the display screen 4 on the surface of the housing 3 conveniently displays the battery level inside the construction machinery during charging, allowing personnel to clearly understand the charging progress and control the charging time, thus improving the convenience of using the mechanical charging display device. After charging the construction machinery is complete, the display screen 4 can control the operation of the electric push rod 10 inside the housing 6. The operation of the electric push rod 10 facilitates the displacement of the U-shaped shovel 11, allowing the inclined surface of the U-shaped shovel 11 to insert between the power connector 9 and the charging base 2, enabling the power connector 9 to engage with the charging base 2. The charging bases 2 are separated from each other, thus physically disconnecting the charging contacts and protecting the battery inside the construction machinery. This reduces the impact of continuous charging. During charging, pressing a set of buttons 19 on the surface of the housing 3 activates the display screen 4 to show the battery level during charging. Another set of buttons 19 controls the electric push rod 10 inside the housing 3, allowing the U-shaped shovel 11 to separate from the charging base 9 and the charging base 2. Then, the spring 12 inside the cover 7 pushes the charging base 9, causing the sliding charging base 9 on the outer periphery of the plug 8 to move and engage with the charging base 2, allowing the circuit to flow. Subsequently, the charging port of the charging base 2 on the outer side of the base 1 can be easily connected to the charging circuit for charging the construction machinery.
