Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile, a wall-mounted device and a charging pile assembly. Background Art

[0002] With the popularization of electric vehicles, the demand for charging piles has also increased day by day. However, most of the existing charging piles have a single function and cannot be flexibly converted and used according to different application scenarios, and cannot meet the multiple needs of users for charging and discharging in fixed places and outdoor temporary situations at the same time. For example, common charging piles are divided into wall-mounted charging piles and portable charging piles. Wall-mounted charging piles are usually fixedly installed in users' homes or specific places, with a fixed position and a stable power connection, suitable for daily conventional charging needs. However, the limitation of wall-mounted charging piles lies in their fixedness, which cannot meet the needs of users for outdoor temporary charging or emergency charging. Portable charging piles have a certain degree of flexibility. Users can carry them to the places where charging is needed, such as in outdoor parking lots, wild camping and other scenarios. However, portable charging piles need to be properly stored when not in use, and may need to find a suitable power socket when charging, and the use process is relatively cumbersome.

[0024] An embodiment of the present invention provides a charging pile 1, referring to Figure 1 and Figure 2, the charging pile 1 includes a charging base body 11 and a charging gun 13 connected to the charging base body 11 through a gun line 12; a first connection structure 14 is provided on the side wall of the charging base body 11, and the charging base body 11 is used for being assembled in a receiving cavity 21 of a wall-mounted device 2, and the first connection structure 14 is used for detachably connecting with a second connection structure 22 arranged in the receiving cavity 21; an avoidance groove 15 is provided on the back surface of the charging base body 11, and a first connection seat 16 is arranged in the avoidance groove 15, and the first connection seat 16 is used for detachably connecting with a second connection seat 5 arranged on any one of the wall-mounted device 2, the adapter plug 3 and the discharge socket 4.

[0025] Wherein, with the charging base body 11 as a reference, the side wall of the charging base body 11 is the peripheral side wall of the charging base body 11, and the back surface of the charging base body 11 is the surface of the charging base body 11 for contacting any one of the wall-mounted device 2, the adapter plug 3 and the discharge socket 4.

[0026] As an example, the charging pile 1 includes a charging base 11 and a charging gun 13; a lightweight functional module and a power supply and signal module are integrated in the charging base 11, the charging base 11 can obtain electrical energy from the outside through a wall mount 2 or an adapter plug 3, and the charging gun 13 is connected to the charging base 11 through a gun line 12, so that the electric car or other electrical loads can be charged through the charging gun 13; at the same time, the charging base 11 can store energy, so that discharge can be achieved through the discharge socket 4 to provide users with electrical energy. The charging pile 1 in this example can be combined with any one of the wall mount 2, the adapter plug 3 and the discharge socket 4, so that the charging pile 1 can be switched arbitrarily among the three application modes of wall-mounted charging pile, portable charging pile and portable discharger according to different application scenarios. In this example, a avoidance groove 15 is provided on the back of the charging base 11, and the avoidance groove 15 is provided in a region away from the gun line 12, and a first connection seat 16 is provided in the avoidance groove 15; when the charging pile 1 is a wall-mounted charging pile application mode, at this time, the charging base 11 is assembled in the accommodating cavity 21 of the wall-mounted device 2, and the first connection seat 16 of the charging pile 1 is detachably connected with the second connection seat 5 provided on the wall-mounted device 2, so that the charging pile 1 is installed on the wall-mounted device 2, and electric energy is obtained from the outside through the wall-mounted device 2. The wall-mounted device 2 is installed in a fixed position, has a stable power connection, and is suitable for daily routine charging needs. In addition, a first connection structure 14 is provided on the side wall of the charging base 11, and the first connection structure 14 can be detachably connected with the second connection structure 22 provided in the accommodating cavity 21 of the wall-mounted device 2, so that the charging pile 1 is safely and securely installed on the wall-mounted device 2, and the charging pile 1 is prevented from being separated from the wall-mounted device 2 due to collision, and it also provides great convenience for installing and removing the charging pile 1. When the charging pile 1 is in the application mode of a portable charging pile, at this time, the first connection socket 16 on the charging pile 1 and the second connection socket 5 set on the adapter plug 3 are detachably connected, so that the charging pile 1 can obtain electrical energy from the outside through the adapter plug 3, which has certain flexibility and the user can carry it to a place where charging is needed. When the charging pile 1 is in the application mode of a portable discharger, at this time, the first connection socket 16 on the charging pile 1 and the second connection socket 5 set on the discharge socket 4 are detachably connected, so that the charging pile 1 can discharge through the discharge socket 4.

The connection male socket and the connection female socket are plugged together to achieve circuit connectivity. When the charging pile 1 is used independently, a unique identification ID is pre-embedded in the first connection socket 16 and the second connection socket 5, so that different identification IDs can be used to automatically determine whether the charging pile 1 is in charging mode or discharging mode, for charging application scenarios or discharging application scenarios.

[0027] In this example, the charging pile 1 can be flexibly and efficiently switched to a wall-mounted charging pile, a portable charging pile or a portable discharger by combining with any one of the wall-mounted device 2, the adapter plug 3 and the discharge socket 4. It can meet the multiple needs of users for charging and discharging in fixed places and outdoors temporarily, improve the convenience and applicability of the charging pile 1, effectively solve the problem of single use scenario of the traditional charging pile 1, take into account the advantages of the wall-mounted mode and the portable mode, with reasonable structural design, strong practicability and popularization value, and can be widely applied to various charging pile 1 products; at the same time, the charging pile 1 and the wall-mounted device 2 can be flexibly disassembled and combined, which provides great convenience for the installation and disassembly of the charging pile 1.

[0028] In one embodiment, referring to Figure 2 、 Figure 7 and Figure 8 , a movable groove 17, a locking groove 18 and an ejecting groove 19 communicating with the movable groove 17 are further provided on the back of the charging substrate 11; the movable groove 17 is located on one side of the avoiding groove 15; the locking groove 18 and the ejecting groove 19 are arranged at intervals along the length direction of the charging substrate 11, and the locking groove 18 and the ejecting groove 19 are located on the same side of the movable groove 17; the movable groove 17 is used for accommodating the locking mechanism 6 provided on the wall-mounted device 2; when the locking mechanism 6 rotates, the locking tongue 63 of the locking mechanism 6 is matched with the locking groove 18, or the top convex 64 of the locking mechanism 6 is matched with the ejecting groove 19.

[0029] As an example, an activity groove 17, a locking groove 18, and an ejection groove 19 are further provided on the back surface of the charging base 11; the activity groove 17 is located on one side of the avoidance groove 15, and the locking groove 18 and the ejection groove 19 communicate with the activity groove 17; the locking groove 18 and the ejection groove 19 are arranged at intervals along the length direction of the charging base 11, and the locking groove 18 and the ejection groove 19 are located on the same side of the activity groove 17; with such an arrangement, the activity groove 17 can accommodate the locking mechanism 6 provided on the wall hanging device 2; when the user drives the locking mechanism 6 to rotate, the locking tongue 63 of the locking mechanism 6 can be clamped in the locking groove 18, and the top convex 64 of the locking mechanism 6 does not abut against the ejection groove 19, so as to lock the charging pile 1 in the accommodating cavity 21 of the wall hanging device 2; or the locking tongue 63 of the locking mechanism 6 is not clamped in the locking groove 18, and the top convex 64 of the locking mechanism 6 abuts against the ejection groove 19, so as to eject 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 locking tongue 63 is not clamped in the locking groove 18, and the topmost end of the top convex 64 abuts against the inner top wall of the ejection groove 19. At this time, the charging pile 1 is in the ejected state, and the charging pile 1 is separated from the wall hanging device 2. When the locking mechanism 6 rotates clockwise (for example, the rotation range is from 0° to 90°), the locking tongue 63 gradually rotates from not being clamped in the locking groove 18 to being clamped in the locking groove 18, and the topmost end of the top convex 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. The charging pile 1 is gradually installed in the accommodating cavity 21 of the wall hanging device 2 until it is finally locked. At this 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° to 90°), the locking tongue 63 gradually rotates from being clamped in the locking groove 18 to not being clamped in the locking groove 18, and the topmost end of the top convex 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. The charging pile 1 is gradually ejected 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 convex 64 and facilitate the rotation of the top convex 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 process of lever-saving support. 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, which further improves the reliability of locking the charging pile 1 and the convenience of ejecting the charging pile 1, and provides great convenience for the installation and disassembly of the charging pile 1.

[0030] In one embodiment, referring to Figure 2 , one of the first connection structure 14 and the second connection structure 22 is a connection protrusion, and the other is a connection recess.

[0031] As an example, one of the first connection structure 14 and the second connection structure 22 is a connection protrusion, and the other is a connection recess; when the charging pile 1 is installed in the accommodation cavity 21 of the wall-mounted device 2, the connection protrusion is snap-fitted with the connection recess, so as to securely install the charging pile 1 on the wall-mounted device 2, avoid the separation of the charging pile 1 and the wall-mounted device 2 caused by collision, and also provide great convenience for the installation and disassembly of the charging pile 1. Wherein, the thickness of the connection protrusion ≤ 3 mm, and the depth of the connection recess ≤ 3 mm; a wear-resistant coating is sprayed on the first connection structure 14 and / or the second connection structure 22, which can reduce the wear caused by friction between the two, thereby increasing the service life of the first connection structure 14 and the second connection structure 22.

[0038] As an example, a guiding structure is provided at the orifice of the accommodating cavity 21. In the depth direction of the accommodating cavity 21, the length of the guiding structure is 28 mm - 29 mm. Specifically, the guiding structure is a V-shaped guiding groove, and the depth of the V-shaped guiding groove is 28 mm - 29 mm; moreover, the angle between the plane where the inner wall of the guiding structure is located and the plane where the orifice of the accommodating cavity 21 is located is 93° - 135°. Such a setting of the guiding structure can provide guiding and limiting for the charging pile 1 and facilitate the installation and disassembly of the charging pile 1.

[0039] In an embodiment, referring to Figure 2 and Figure 6 , a locking mechanism 6 is arranged in the accommodating cavity 21 of the wall-mounted device 2. The locking mechanism 6 and the second connecting seat 5 are arranged at intervals in the first direction and are used to connect with the charging pile 1 to realize locking or ejecting the charging pile 1.

[0040] Wherein, the first direction is the length direction of the wall-mounted device 2, that is, the length direction of the accommodating cavity 21.

[0041] As an example, a locking mechanism 6 is arranged in the accommodating cavity 21 of the wall-mounted device 2. The locking mechanism 6 and the second connecting seat 5 are arranged at intervals in the first direction and are connected with the charging pile 1 to realize 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 moving groove 17; when the user drives the locking mechanism 6 to rotate, the locking mechanism 6 can be clamped in the locking groove 18, and the locking mechanism 6 does not abut against the ejecting groove 19, so as to realize locking the charging pile 1 in the accommodating cavity 21 of the wall-mounted device 2, or the locking mechanism 6 is not clamped in the locking groove 18, and the locking mechanism 6 abuts against the ejecting groove 19, so as to realize ejecting the charging pile 1 from the accommodating cavity 21 of the wall-mounted device 2; the locking or ejecting of the charging pile 1 is completed synchronously by single-hand operation, which improves the reliability of locking the charging pile 1 and the convenience of ejecting the charging pile 1, and provides great convenience for the installation and disassembly of the charging pile 1.

[0042] In an embodiment, referring to Figure 2 、 Figure 6 、 Figure 7 and Figure 8, the locking mechanism 6 includes a support 61, a connecting rod 62, a locking tongue 63 and a top convex 64; the support 61 is installed in the accommodating cavity 21 and is arranged at an interval from the second connecting seat 5 in the first direction; the connecting rod 62 is rotatably installed on the support 61 in the first direction, and one end of the connecting rod 62 extends outside the accommodating cavity 21; the top convex 64 and the locking tongue 63 are arranged at an interval on the connecting rod 62 in the first direction, and the projection of the top convex 64 in the first direction is misaligned with the locking tongue 63; when the connecting rod 62 rotates, the locking tongue 63 is matched with the locking groove 18 on the charging pile 1 to realize locking the charging pile 1, or the top convex 64 is matched with the ejection groove 19 on the charging pile 1 to realize ejecting the charging pile 1.

[0043] Wherein, the first direction can also be said to be the axial direction of the connecting rod 62.

[0044] As an example, the locking mechanism 6 includes a support 61, a connecting rod 62, a locking tongue 63 and a top convex 64. During installation, the support 61 is installed in the accommodating cavity 21, spaced apart from the second connecting seat 5 in the first direction, leaving an installation space for the charging pile 1 to avoid interference. Specifically, a fixing groove is provided on the inner bottom wall of the accommodating cavity 21, and the support 61 is embedded in the fixing groove, which can limit the support 61 and prevent the displacement of the locking mechanism 6 caused by the movement of the support 61, so that the charging pile 1 cannot be locked or ejected. The connecting rod 62 is rotatably installed on the support 61 in the first direction. Specifically, the support 61 is located 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 outside the accommodating cavity 21, facilitating the user to rotate the connecting rod 62. The top convex 64 and the locking tongue 63 are arranged at intervals on the connecting rod 62 in the first direction, and the projection of the top convex 64 in the first direction is misaligned with the locking tongue 63. With such a setting, when the user drives the locking mechanism 6 to rotate, the locking tongue 63 of the locking mechanism 6 can be engaged in the locking groove 18, and the top convex 64 of the locking mechanism 6 does not abut against the ejection groove 19, so as to lock the charging pile 1 in the accommodating cavity 21 of the wall-mounted device 2, or the locking tongue 63 of the locking mechanism 6 is not engaged in the locking groove 18, and the top convex 64 of the locking mechanism 6 abuts against the ejection groove 19, so as to eject the charging pile 1 from the accommodating cavity 21 of the wall-mounted device 2. The specific process is as follows: when the locking mechanism 6 is in the initial state, the locking tongue 63 is not engaged in the locking groove 18, and the top of the top convex 64 abuts against the inner top wall of the ejection groove 19. At this time, the charging pile 1 is in the ejected state, and the charging pile 1 is separated from the wall-mounted device 2. When the locking mechanism 6 rotates clockwise (for example, the rotation range is from 0° to 90°), the locking tongue 63 gradually rotates from not being engaged in the locking groove 18 to being engaged in the locking groove 18, and the top of the top convex 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. The charging pile 1 is gradually embedded in the accommodating cavity 21 of the wall-mounted device 2 until it is finally locked. At this time, the charging pile 1 and the wall-mounted device 2 are in the locked state. When the locking mechanism 6 rotates counterclockwise (for example, the rotation range is from 0° to 90°), the locking tongue 63 gradually rotates from being engaged in the locking groove 18 to not being engaged in the locking groove 18, and the top of the top convex 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. The charging pile 1 is gradually ejected from the accommodating cavity 21 of the wall-mounted device 2 until the charging pile 1 is separated from the wall-mounted device 2. Among them, the inner top wall of the ejection groove 19 is an inclined wall, which can reduce the resistance to the top convex 64 and facilitate the rotation of the top convex 64. When the charging pile 1 and the wall-mounted device 2 are in the state between separation and locking, the charging pile 1 and the wall-mounted device 2 are in the process of lever-saving support.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 reliability of locking the charging pile 1 and the convenience of ejecting the charging pile 1, and provide great convenience for the installation and disassembly of the charging pile 1.

[0045] In one embodiment, referring to Figure 2 and Figure 6 , the length of the top convex 64 is greater than the length of the locking tongue 63.

[0046] As an example, the length of the top convex 64 is greater than the length of the locking tongue 63. Such a setting can ensure that when the top convex 64 abuts against the ejection groove 19, the locking tongue 63 will not be engaged with the locking groove 18, avoiding the situation that the charging pile 1 cannot be ejected.

[0047] In one embodiment, referring to Figure 2 and Figure 6 , the locking mechanism 6 further includes at least one of a guiding and limiting member 65 and an external rotating handle 66; the guiding and limiting member 65 is installed in the accommodating cavity 21 and is arranged at an interval from the connecting rod 62 in the second direction; the guiding and limiting member 65 is used for guiding the locking tongue 63 and limiting the top convex 64; the external rotating handle 66 is installed on the part of the connecting rod 62 extending outside the accommodating cavity 21.

[0048] Wherein, the second direction is perpendicular to the first direction, the second direction is the width direction of the wall hanging device 2, that is, the width direction of the accommodating cavity 21, and can also be said to be the radial direction of the connecting rod 62.

[0049] As an example, the locking mechanism 6 further includes at least one of a guiding and limiting member 65 and an external rotating handle 66; during installation, the guiding and limiting member 65 is installed in the accommodating cavity 21 and is arranged at an interval from the connecting rod 62 in the second direction; when the connecting rod 62 rotates, the guiding and limiting member 65 can guide the locking tongue 63 to make the rotation of the locking tongue 63 smoother, and the guiding and limiting member 65 can be set as an arc-shaped structure to limit the locking tongue 63 and prevent the locking tongue 63 from rotating excessively and affecting the next use; the guiding and limiting member 65 can also limit the top convex 64 to prevent the top convex 64 from rotating excessively and being unable to eject the charging pile 1. The external rotating handle 66 is installed on the part of the connecting rod 62 extending outside the accommodating cavity 21 and can be used as a handle to facilitate the user to drive the connecting rod 62 to rotate.
