Description

TECHNICAL FIELD

[0001] The application relates to the technical field of excavator charging protection, and in particular to a charging head protection structure and an electric excavator with the same. BACKGROUND

[0002] New energy excavators are advanced devices driven by electricity, which can play an excellent role in various construction environments. However, since the working environment of the excavator is usually very complex and harsh, the protection measures for the device are particularly important. In order to protect the charging hole of the excavator, designers usually install a flip cover to prevent dust and sundries from entering. However, during the actual charging process, the flip cover often resists the charging head due to its own weight, so that the charging head cannot be stably inserted into the charging hole. This condition not only brings inconvenience to the operator, but also may affect the charging efficiency due to the frequent falling of the charging head, and even may cause damage to the charging head and the charging hole. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at solving the above-mentioned problems and provides a charging head protection structure and an electric excavator with the same.

[0004] The technical scheme of the application is implemented as follows:

[0005] In the first aspect, the application provides a charging head protection structure, which is installed on a charging carrier, and the protection structure comprises:

[0006] A flip cover is rotatably installed on the charging carrier. When the flip cover is in a flipped-up posture, the charging head is exposed, and when the flip cover is in a closed posture, the flip cover shields the charging head.

[0007] A positioning member is installed on the charging carrier near the flip cover, and is used to keep the flip cover in the flipped-up posture.

[0008] The advantages or beneficial effects of the above technical scheme at least include:

[0009] In the second aspect, the application further provides an electric excavator with the structure, and the electric excavator has the charging head protection structure described above, wherein the charging carrier is the electric excavator.

[0010] The advantages or beneficial effects of the above technical scheme at least include:

[0011] The positioner can effectively fix the posture of the flip cover, thereby avoiding that the flip cover accidentally touches the charging head during charging, and causing a safety hazard. In addition, the positioner has two different embodiments of a magnet and a supporting rod to adapt to various different on-site use conditions. Users can flexibly select the most suitable embodiment according to actual environment and requirements. Such a design not only improves the convenience of use, but also greatly enhances the safety of the charging process, and ensures the safety of users during charging. BRIEF DESCRIPTION OF DRAWINGS

[0027] Reference Figure 1 and Figure 2 A charging head protection structure is installed on a charging carrier 10, and the protection structure includes:

[0028] The flip cover 11 is rotatably mounted on the charging carrier 10. When the flip cover 11 is in the flipped-up position, the charging head 12 is exposed. When the flip cover 11 is in the closed position, the flip cover 11 covers the charging head 12.

[0029] The positioning component 20 is installed on the part of the charging carrier 10 near the flip cover 11 to keep the flip cover 11 in a flipped-up position and prevent the flip cover 11 from falling down naturally and damaging the charging head 12 when the carrier is charging.

[0030] There are two embodiments for the specific structure of the positioning element 20.

[0031] In the first embodiment, as shown in Figure 3 and Figure 4 The positioning member 20 comprises a magnet 21, the bottom of which is attracted to the flip cover 11. Specifically, the magnet 21 has an extension at the position where the charging carrier 10 is located on the top of the flip cover 11. The top of the magnet 21 is provided with a bolt 211 which extends through the extension and is screwed with a nut 212 for fixing the magnet 21. The nut 212 and the bolt 211 are also convenient for replacing the magnet 21.

[0032] Based on the above structure, the magnet 21 is installed symmetrically left and right of the axis of the flip cover 11 in at least one pair, and each magnet 21 has an attractive force of at least 5N to ensure that the flip cover 11 can be kept in the flipped position.

[0033] In the second embodiment, the positioning member 20 is further used to keep the flip cover 11 in the closed position

[0034] The positioning member 20 comprises a support rod 22 which is slidably installed on the charging carrier 10 near the left and right sides of the flip cover 11. One end of the support rod 22 can be extended or retracted from the surface of the charging carrier 10.

[0035] As shown in the upper half of the figure, when the flip cover 11 is in the closed position, the support rod 22 abuts against the top of the flip cover 11. Figure 5 As shown in the lower half of the figure, when the flip cover 11 is in the flipped position, the support rod 22 abuts against the bottom of the flip cover 11.

[0036] Figure 5 This ensures that the flip cover 11 can be kept in position whether in the closed position or the flipped position.

[0037] Based on the further improvement of the above structure, the positioning member 20 further comprises:

[0038] A push rod 23 is fixed on the support rod 22, the axial direction of which is perpendicular to the axial direction of the support rod 22. One end of the push rod 23 extends out of the surface of the charging carrier 10, which is convenient for the user to push the support rod 22 left and right, so that the end of the support rod 22 can be extended or retracted from the surface of the carrier.

[0039] A positioning sleeve 24 is movably sleeved on the support rod 22. As shown in The charging carrier 10 is provided with a positioning hole 13 which is adapted to the positioning sleeve 24. The positioning sleeve 24 can be embedded in or extended out of the positioning hole 13.

[0040] Figure 8 The positioning sleeve 24 is movably sleeved on the support rod 22. As shown in Figure 7 ​As shown, when the positioning sleeve 24 is embedded in the positioning hole 13, the position of the support rod 22 is unchanged, the positioning hole 13 is provided with two, corresponding to the position of the positioning sleeve 24 when the support rod 22 is extended and the position of the positioning sleeve 24 when the support rod 22 is retracted, in use, the positioning sleeve 24 needs to be extended out of the positioning hole 13, and then the support rod 22 can be moved;

[0041] Based on the further improvement of the above structure, the positioning piece 20 further comprises a limiting cap 231 which is detachably installed at the end of the lever 23 and is used for limiting the moving stroke of the positioning sleeve 24, so as to avoid the positioning sleeve 24 from being detached from the lever 23.

[0042] The embodiment of the utility model provides a kind of electric excavator with the structure, electric excavator has the above-mentioned charging head 12 protection structure, wherein, charging carrier 10 is electric excavator, the implementation effect of electric excavator is described in the foregoing, this place does not repeat.

[0043] In the description of the present application, it should be pointed out that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0044] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present application, and do not limit the scope of the present application. Based on the above disclosure, other changes or modifications can also be made by those skilled in the art, and these changes or modifications are still within the scope of the present application.
