Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of charging piles, in particular to a charging pile, a wall hanging device and a charging pile assembly. BACKGROUND

[0002] With the popularization of electric vehicles, the demand for charging piles is also increasing. However, most of the existing charging piles have single function and cannot be flexibly converted and used according to different application scenarios, which cannot meet the multiple needs of users in fixed places and outdoor temporary charging and discharging. For example, common charging piles are divided into wall-mounted charging piles and portable charging piles. The wall-mounted charging pile is usually fixedly installed in the user's home or a specific place, has a fixed position and stable power connection, and is suitable for daily regular charging needs. However, the limitation of the wall-mounted charging pile is its fixity, which cannot meet the needs of users for outdoor temporary charging or emergency charging. The portable charging pile has a certain flexibility, and users can carry it to the place where charging is needed for use, such as outdoor parking lots, field camping and other scenes. However, the portable charging pile needs to be properly stored when not in use, and may need to find a suitable power socket when charging, which is relatively cumbersome in the use process.

[0075] In an embodiment, referring to Figure 2 and Figure 6 , the accommodating cavity 21 of the wall hanging device 2 is provided with a locking mechanism 6, the locking mechanism 6 is spaced apart from the second connecting seat 5 along the first direction, and is used to be connected with the charging pile 1 to achieve locking or ejecting the charging pile 1.

[0076] Among them, the first direction is the length direction of the wall hanging device 2, that is, the length direction of the accommodating cavity 21.

[0077] As an example, the accommodating cavity 21 of the wall hanging device 2 is provided with a locking mechanism 6, the locking mechanism 6 is spaced apart from the second connecting seat 5 along the first direction, and is connected with the charging pile 1 to achieve locking or ejecting the charging pile 1; specifically, when the charging pile 1 is installed in the accommodating cavity 21, the locking mechanism 6 is located in the movable groove 17; when the user drives the locking mechanism 6 to rotate, the locking mechanism 6 can be clamped in the locking groove 18, the locking mechanism 6 does not abut against the ejecting groove 19, so as to achieve locking the charging pile 1 in the accommodating cavity 21 of the wall hanging device 2, or the locking mechanism 6 is not clamped in the locking groove 18, the locking mechanism 6 abuts against the ejecting groove 19, so as to achieve ejecting the charging pile 1 from the accommodating cavity 21 of the wall hanging device 2; through single-handed operation, the locking or ejecting of the charging pile 1 is completed synchronously, the reliability of locking the charging pile 1 and the convenience of ejecting the charging pile 1 are improved, and great convenience is provided for the installation and removal of the charging pile 1.

[0078] In an embodiment, referring to Figure 2 , Figure 6 , Figure 7 and Figure 8The locking mechanism 6 comprises a support 61, a connecting rod 62, a locking tongue 63 and a top protrusion 64. The support 61 is installed in the accommodating cavity 21 and is arranged along the first direction away from the second connecting seat 5. The connecting rod 62 is rotatably installed on the support 61 along the first direction, and one end of the connecting rod 62 extends out of the accommodating cavity 21. The top protrusion 64 and the locking tongue 63 are arranged on the connecting rod 62 along the first direction, and the projection of the top protrusion 64 on the first direction is distributed away from the locking tongue 63. When the connecting rod 62 rotates, the locking tongue 63 matches the locking groove 18 on the charging pile 1 to achieve the locking of the charging pile 1, or the top protrusion 64 matches the ejection groove 19 on the charging pile 1 to achieve the ejection of the charging pile 1.

[0079] The first direction can also be referred to as the axial direction of the connecting rod 62.

[0080] As an example, the locking mechanism 6 includes a support 61, a connecting rod 62, a lock tongue 63 and a top protrusion 64; when installed, the support 61 is installed in the accommodating cavity 21 and is spaced apart from the second connecting seat 5 in the first direction, leaving a mounting space for the charging pile 1 to avoid interference; specifically, a fixed groove is provided on the inner bottom wall of the accommodating cavity 21, and the support 61 is embedded in the fixed groove, which can limit the support 61 and prevent the support 61 from moving to cause the locking mechanism 6 to be misaligned and unable to lock or eject the charging pile 1. The connecting rod 62 is rotatably installed on the support 61 in the first direction, specifically at 1 / 3 of the second end of the connecting rod 62, which can ensure the stability of the connecting rod 62. One end of the connecting rod 62 extends out of the accommodating cavity 21 to provide convenience for the user to rotate the connecting rod 62. The top protrusion 64 and the lock tongue 63 are spaced apart on the connecting rod 62 in the first direction, and the projection of the top protrusion 64 in the first direction is misaligned with the lock tongue 63; in this way, when the user drives the locking mechanism 6 to rotate, the lock tongue 63 of the locking mechanism 6 can be clamped in the locking groove 18, and the top protrusion 64 of the locking mechanism 6 does not abut against the ejection groove 19, thereby realizing the locking of the charging pile 1 in the accommodating cavity 21 of the wall hanging device 2, or the lock tongue 63 of the locking mechanism 6 is not clamped in the locking groove 18, and the top protrusion 64 of the locking mechanism 6 abuts against the ejection groove 19, thereby realizing the ejection of the charging pile 1 from the accommodating cavity 21 of the wall hanging device 2. The specific process is as follows: when the locking mechanism 6 is in the initial state, the lock tongue 63 is not clamped in the locking groove 18, and the top end of the top protrusion 64 abuts against the inner top wall of the ejection groove 19, at which time the charging pile 1 is in the ejected state, and the charging pile 1 and the wall hanging device 2 are in the separated state. When the locking mechanism 6 rotates clockwise (for example, the rotation range is from 0°-90°), the lock tongue 63 gradually rotates from not being clamped in the locking groove 18 to being clamped in the locking groove 18, and the top end of the top protrusion 64 gradually rotates from abutting against the inner top wall of the ejection groove 19 to not abutting against the inner top wall of the ejection groove 19, and the charging pile 1 gradually embeds in the accommodating cavity 21 of the wall hanging device 2 until it is finally locked, at which time the charging pile 1 and the wall hanging device 2 are in the locked state. When the locking mechanism 6 rotates counterclockwise (for example, the rotation range is from 0°-90°), the lock tongue 63 gradually rotates from being clamped in the locking groove 18 to not being clamped in the locking groove 18, and the top end of the top protrusion 64 gradually rotates from not abutting against the inner top wall of the ejection groove 19 to abutting against the inner top wall of the ejection groove 19, and the charging pile 1 gradually ejects from the accommodating cavity 21 of the wall hanging device 2 until the charging pile 1 and the wall hanging device 2 are in the separated state. Among them, the inner top wall of the ejection groove 19 is an inclined wall, which can reduce the resistance to the top protrusion 64 and provide convenience for the rotation of the top protrusion 64; when the charging pile 1 and the wall hanging device 2 are in the state between separation and locking, the charging pile 1 and the wall hanging device 2 are in the lever power-saving supporting process.In addition, the number of the locking grooves 18 and the number of the ejection grooves 19 are both two, and the two locking grooves 18 are located between the two ejection grooves 19, so as to further improve the firmness of the locking of the charging pile 1 and the convenience of the ejection of the charging pile 1, and provide great convenience for the installation and disassembly of the charging pile 1.

[0081] In an embodiment, referring to Figure 2 and Figure 6 , the length of the top protrusion 64 is greater than the length of the lock tongue 63.

[0082] As an example, the length of the top protrusion 64 is greater than the length of the lock tongue 63, so that when the top protrusion 64 abuts against the ejection groove 19, the lock tongue 63 cannot be clamped with the locking groove 18, avoiding the charging pile 1 from being unable to be ejected.
