Description

Technical Field

[0001] This utility model relates to the field of chargers, and more particularly to a charger mounting base and a charger. Background Technology

[0002] With the development of electromechanical technology, the power and voltage of chargers for electromechanical equipment are constantly increasing, and the size of chargers is getting larger and larger, making installation more and more difficult. For equipment such as large equipment, household appliances, and electric vehicles, their chargers need to be installed on walls or the ground using mounting brackets. This installation method requires first drilling fixing holes at the mounting location, setting connectors, then connecting the mounting bracket to the connectors, and finally connecting the charger to the mounting bracket. However, the above installation process is prone to problems such as the fixing hole distance being too large or too small, and the connector angle being tilted, failing to meet installation requirements. This necessitates removing the connectors and re-drilling, resulting in low installation efficiency. Currently, adjustable mounting brackets are used to improve installation efficiency. For example, Chinese patent CN113513683A discloses an adjustable mounting base for a vertical charging pile. This base incorporates a width adjustment slider and a lifting mechanism, allowing for adjustment of the charging pile's installation width and height. However, this mounting base requires a high degree of flatness at the mounting location. It will tilt when facing uneven ground, causing the charging pile to tilt, and the mounting base will experience uneven stress, affecting the overall stability of the charging pile. Summary of the Invention

[0003] To address the technical problem of limited adaptability of the aforementioned mounting base, which is unsuitable for uneven mounting positions, this utility model provides a charger mounting base and charger. The mounting base has high flexibility and adaptability, and will not tilt on uneven mounting positions, ensuring stable installation of the charger and uniform force distribution, thereby improving the stability of the charger.

[0004] The specific technical solution of this utility model is as follows:

[0005] A charger mounting base includes a mounting base, a fixing plate, and a plurality of connectors. The mounting base has placement holes corresponding to the connectors. The fixing plate is connected to the mounting base, and an installation space is formed between the two. The connector includes a mounting part and a connecting part. The connecting part is disposed within the installation space. One end of the mounting part passes through the corresponding placement hole and extends out of the mounting base. The installation space is provided with a first limiting part that restricts the connecting part from extending out of the corresponding placement hole. The thickness H1 of the connecting part is less than the thickness H2 of the installation space.

[0006] The aforementioned mounting base connects to the mounting position via the mounting part of the connector. The connector is located in the mounting space formed by the mounting base and the fixing plate. The mounting base has placement holes to facilitate the connector's mounting part extending out of the mounting base and connecting to the mounting position. A first limiting part is also provided within the mounting space to confine the connector's connecting part within the mounting space. Due to the thickness difference between the connecting part and the mounting space, the connector has a certain amount of room to move in the thickness direction of the mounting space. This not only allows the extension distance of the mounting part to be adjusted as needed but also reduces frictional resistance during connector movement, giving the mounting base high flexibility and increasing its adaptability. When facing uneven mounting positions, the mounting part located at concave areas extends further to connect with the connector at the mounting position, while the mounting part located at convex areas extends further to connect with the connector at the mounting position. This allows the mounting base to achieve the same installation effect on uneven mounting positions as it does on flat surfaces, with even force distribution and good stability, contributing to a stable connection of the charger.

[0007] Preferably, the maximum extension length of the mounting part beyond the mounting base is L, where H2-H1≥L.

[0008] In the above technical solution, the maximum extension length of the mounting part is not greater than the thickness difference between the connecting part and the mounting space, so that the mounting part can be retracted into the mounting space. When the mounting base is accidentally dropped, the mounting part will not be impacted, thus preventing damage to the connector.

[0009] Preferably, the placement hole is larger in length than the mounting portion, and the mounting space is larger in length than the connecting portion, so that the connector has room for movement in length. And / or, the placement hole is larger in width than the mounting portion, and the mounting space is larger in width than the connecting portion, so that the connector has room for movement in width.

[0010] In the above technical solution, the connector has room for movement in both the length and width directions, meaning it can move horizontally and vertically. The connector has an adjustment range, which is limited by the positional relationship between the mounting part and the placement hole. When the distance between the fixing holes on the mounting position is too large or too small, the connector can be moved to align the fixing holes, completing the connection between the mounting base and the mounting position without the need for re-drilling, further improving the flexibility of the mounting base.

[0011] Preferably, the end of the connecting portion away from the mounting portion is provided with a limiting rib, and the fixing plate is provided with a limiting groove. The limiting rib is at least partially disposed within the limiting groove. The dimension of the limiting groove in the length direction is greater than the dimension of the limiting rib in the length direction, so that the connector has room for movement in the length direction. The difference in dimension between the limiting groove and the limiting rib in the length direction is less than the difference in dimension between the placement hole and the mounting portion in the length direction. And / or, the dimension of the limiting groove in the width direction is greater than the dimension of the limiting rib in the width direction, so that the connector has room for movement in the width direction. The difference in dimension between the limiting groove and the limiting rib in the width direction is less than the difference in dimension between the placement hole and the mounting portion in the width direction.

[0012] In the above technical solution, a limiting rib is provided on the connector, and a limiting groove corresponding to the position of the limiting rib is provided on the fixing plate. The adjustment range of the connector is limited by the positional relationship between the limiting rib and the limiting groove, so that the mounting part will not frequently contact the edge of the placement hole and cause wear, thereby improving the service life of the mounting base.

[0013] Preferably, when the connecting portion contacts the first limiting portion, the limiting rib and the limiting groove partially overlap in the thickness direction.

[0014] In the above technical solution, when the mounting part extends to its maximum distance, the limiting rib and the limiting groove still partially overlap in the thickness direction, ensuring that the horizontal and vertical movement of the connector is always controlled.

[0015] Preferably, the connector is rotatably connected between the mounting base and the fixing plate, and the rotation axis of the connector is parallel to the thickness direction.

[0016] In the above technical solution, the connector is rotatable. When the spacing between the connectors on the mounting position is close, far apart, or tilted at an angle, the installation distance and angle can be adjusted by rotating the angle of a single connector, further improving the flexibility of the mounting base.

[0017] Preferably, the end of the connecting part away from the mounting part is provided with a limiting rib, the fixing plate is provided with a limiting groove, the limiting rib is at least partially provided in the limiting groove, and a second limiting part is provided on the side wall of the limiting groove, the second limiting part being used for the rotation angle of the limiting rib in the limiting groove.

[0018] In the above technical solution, the connector is provided with a limiting rib, the fixing plate is provided with a limiting groove, and the limiting groove is provided with a second limiting part. The rotation angle of the connector is limited by the positional relationship of the limiting rib in the limiting groove, thereby improving the alignment efficiency of the connector and the connecting parts.

[0019] Preferably, the end of the mounting part away from the connecting part is provided with a hanging hole, and the fixing plate is detachably connected to the mounting base.

[0020] In the above technical solution, the connector connects to the connector on the mounting position via a hanging hole, which is simple to operate, has good stability, and is easy to install and remove. The fixing plate and the mounting base are detachably connected, which facilitates the maintenance and replacement of the connector and improves the reliability of the mounting base.

[0021] Preferably, the mounting base has several grooves, the placement hole is opened in the groove, one side of the groove has a chamfer, the fixing plate is connected to the groove and its size is adapted to the bottom of the groove, and the edge of the fixing plate has a protrusion facing outward, the protrusion facing the groove.

[0022] In the above technical solution, each groove is equipped with a fixing plate, and the groove has at least one placement hole. The connector is located in the installation space formed by the groove and the fixing plate, and the number of connectors corresponds to the number of placement holes. Each groove is equipped with an independent fixing plate, and the size of each installation space can be adjusted according to actual needs, increasing the adaptability of the mounting base. The groove has a chamfer, which facilitates the fixing plate to enter the bottom of the groove and connect with it. At the same time, it prevents the fixing plate from shifting during the connection process, improving the accuracy and efficiency of the connection.

[0023] On the other hand, a charger is also proposed, wherein the charger includes a mounting base, and the mounting base is a charger mounting base as described above.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] High flexibility and wide adaptability: By rotatably setting the connector in the installation space formed by the mounting base and the fixing plate, and having room for movement in the thickness, length and width directions of the installation space, the connection range and connection flexibility of the connector are expanded. It can achieve the same installation effect on uneven installation positions as on flat surfaces. Furthermore, the mounting base can also be installed when the spacing between the connectors at the installation position is too large or too small or the angle is tilted, with a high degree of fault tolerance.

[0026] Simple to operate and highly stable: It connects to the connector on the mounting position through the connector's hanging hole, making operation simple and the connection secure. The connector's extension distance can be adjusted, allowing it to be installed smoothly on uneven mounting positions with uniform force and high stability. Attached Figure Description

[0035] The present invention will be further described below with reference to embodiments. Unless otherwise specified, all devices, connection structures, and methods involved in this invention are known in the art.

[0036] Example 1

[0037] Reference Figures 1 to 6 As shown, this utility model provides a charger mounting base, including a mounting base 1, a connector 2, and a fixing plate 3. The mounting base 1 has four placement holes 4. The fixing plate 3 is connected to the mounting base 1, and the two form a mounting space 11. The connector 2 is located in the mounting space 11 and corresponds one-to-one with the placement holes 4 on the mounting base 1. The connector 2 consists of a mounting part 21 and a connecting part 22. One end of the mounting part 21 passes through the corresponding placement hole 4 and extends out of the mounting base 1, while the other end is connected to the connecting part 22. The connecting part 22 is located within the mounting space 11. A first limiting part 8 is provided within the mounting space 11 to restrict the connecting part 22 from extending out of the corresponding placement hole 4. The thickness of the connecting part 22 is H1, and the thickness of the mounting space 11 is H2, where H1 is less than H2. ， This allows the connecting part 22 to have room to move in the thickness direction of the mounting space 11, with the range of movement being the difference in thickness between the two. In the figure, the Z direction represents the thickness direction.

[0038] This device is detachably connected to the mounting position via the mounting part 21 of connector 2. Connector 2 is located in the mounting space 11 formed by mounting base 1 and fixing plate 3. Mounting base 1 has placement holes 4 to facilitate the mounting part 21 of connector 2 extending out of mounting base 1 and connecting to the mounting position. The mounting space 11 has a first limiting part 8 to restrict the connecting part 22 of connector 2 within the mounting space 11, preventing connector 2 from detaching from the mounting base. The thickness difference between the connecting part 22 and the mounting space 11 not only allows connector 2 a certain amount of movement in the thickness direction of the mounting space 11, i.e., connector 2 can move inward or outward, and the extension distance of mounting part 21 can be adjusted as needed, but also reduces frictional resistance when connector 2 moves, giving the mounting base high flexibility and increasing its adaptability. Even on uneven mounting positions, the mounting base can remain stable. The mounting base and charger can be an integral or separate structure.

[0039] The method for installing this device on a wall is as follows: Determine the installation location, and according to the number and layout of connectors 2, drill corresponding fixing holes in the selected wall surface. Install screws in the fixing holes, and connect the connectors 2 of the mounting base to the screws to complete the fixing of the mounting base. If the mounting base and charger are separate structures, they can be combined before installing the mounting base, or the charger can be combined with the mounting base after it is fixed. For disassembly, simply separate the connectors 2 from the screws to remove the charger. When facing uneven wall surfaces, the mounting part 21 located in the recessed area extends further to connect with the connector at the mounting position, while the mounting part 21 located in the convex area extends further to connect with the connector at the mounting position. This allows the mounting base to achieve the same installation effect on uneven surfaces as on flat surfaces, with even force distribution and good stability, contributing to a stable connection of the charger. This device is also suitable for floor installation; the installation method can be adjusted according to the actual situation.

[0040] Example 2

[0041] Based on Example 1, such as Figures 1 to 6 As shown, this utility model provides a charger mounting base. The mounting base 1 has two parallel grooves 7, each groove 7 containing two placement holes 4, which are parallel to each other. One side of each groove 7 has a chamfer 71. A fixing plate 3 is located within the groove 7 and its dimensions are adapted to the bottom of the groove 7. The edge of the fixing plate 3 has an outwardly extending protrusion 31 facing the groove 7. The fixing plate 3 has three equally spaced screw holes, and the fixing plate 3 is connected to the groove 7 by screws. A connector 2 is rotatably connected between the groove 7 and the fixing plate 3. The connector 2 consists of a mounting part 21 and a connecting part 22. The end of the mounting part 21 away from the connecting part 22 has a hanging hole 10, which consists of a narrow part and a wide part, with the narrow part located above the wide part. The maximum extension length of the mounting part 21 beyond the mounting base 1 is L, where H2-H1≥L.

[0042] In this embodiment, the dimension of the placement hole 4 in the length direction is larger than the dimension of the mounting portion 21 in the length direction, and the dimension of the mounting space 11 in the length direction is larger than the dimension of the connecting portion 22 in the length direction, so that the connector 2 has room for movement in the length direction, that is, the connector 2 can move in the horizontal direction. Simultaneously, the dimension of the placement hole 4 in the width direction is larger than the dimension of the mounting portion 21 in the width direction, and the dimension of the mounting space 11 in the width direction is larger than the dimension of the connecting portion 22 in the width direction, so that the connector 2 has room for movement in the width direction, that is, the connector 2 can move in the vertical direction. The adjustable distance of a single connector in the horizontal direction is A, and the adjustable distance of a single connector in the vertical direction is B, 0 ≤ B ≤ A. In the figure, the X direction is the width direction; the Y direction is the length direction; and the Z direction is the thickness direction.

[0043] In this embodiment, each groove 7 is equipped with an independent fixing plate 3, which can adjust the size of each installation space 11 according to actual needs, increasing the adaptability of the mounting base; the groove 7 has a chamfer, which facilitates the fixing plate 3 to enter the bottom of the groove and connect with it, and at the same time, prevents the fixing plate 3 from being misaligned during the connection process, improving the accuracy and efficiency of the connection; the fixing plate 3 is detachably connected to the mounting base 1, which facilitates the maintenance and replacement of the connector 2 and improves the reliability of the mounting base; the connector 2 is connected to the connector on the mounting position through the hanging hole 10, which is simple to operate, has good fixation, and is easy to install and remove; the maximum extension length of the mounting part 21 is not greater than the thickness difference between the connecting part 22 and the mounting space 11, so that the mounting part 21 can be retracted into the mounting space 11. When the mounting base is accidentally dropped, the mounting part 21 will not be impacted, causing damage to the connector 2; the positional relationship between the mounting part 21 and the placement hole 4 makes the movement distance of the connector 2 controllable, improving the alignment efficiency of the connector 2 and the connector on the mounting position.

[0044] In this embodiment, connector 2 is rotatable, and its rotation axis is parallel to the Z-direction. When the spacing between connectors at the mounting position is too close, too far, or angularly tilted, the mounting distance and angle can be adjusted by rotating a single connector 2, improving the flexibility of the mounting base. Connector 2 has room for movement in the thickness, length, and width directions of the mounting space 11, meaning that connector 2 can move inward or outward, as well as horizontally and vertically. Connector 2 has high flexibility, a large adjustable distance, and less frictional resistance when rotating or moving. When the distance between fixing holes at the mounting position is too large, too small, or angularly tilted, the mounting base can be fixed in the mounting position by moving connector 2 to align the connectors in the fixing holes, eliminating the need for re-drilling and further improving the flexibility of the mounting base.

[0045] The method for installing this device on a wall is as follows: Determine the installation location, and according to the number and layout of connectors 2, drill corresponding fixing holes in the selected wall. Install screws in the fixing holes, and adjust the extension distance, spacing, and angle of connectors 2 according to the flatness of the wall and the screw installation spacing. The screws should first pass through the wide part of the hanging hole 10, then into the narrow part of the hanging hole 10, and be secured by the retaining plate in the hanging hole 10, thus completing the connection between the mounting base and the screws. If the mounting base and charger are separate structures, they can be combined before installing the mounting base, or the charger can be combined with the mounting base after it is fixed. After the charger is hung on the wall, connectors 2 will automatically return to the vertical direction due to gravity. For disassembly, simply separate connectors 2 from the screws to remove the charger. This device is also suitable for ground installation; the installation method can be adjusted according to the actual situation.

[0046] Example 3

[0047] Based on Example 1, such as Figures 1 to 6 As shown, this utility model provides a charger mounting base, in which a connector 2 is rotatably connected between a mounting space 11 and a fixing plate 3. The rotation axis of the connector 2 is parallel to the Z-direction. The connector 2 consists of a mounting part 21 and a connecting part 22. A limiting rib 5 is provided at the end of the connecting part 22 away from the mounting part 21. A limiting groove 6 is provided on the fixing plate 3, and the limiting rib 5 is at least partially disposed in the limiting groove 6. The limiting groove 6 is approximately arrow-shaped, and a second limiting part 9 is provided on the side wall of the arrowhead. Its dimension in the length direction is greater than that of the limiting rib 5 in the length direction. At the same time, the dimension of the placement hole 4 in the length direction is greater than that of the mounting part 21 in the length direction, and the dimension of the mounting space 11 in the length direction is greater than that of the connecting part 22 in the length direction, so that the connector 2 has room for movement in the length direction. The difference in the length direction of the limiting groove 6 and the limiting rib 5 is less than the difference in the length direction of the placement hole 4 and the mounting part 21. The dimension of the limiting groove 6 in the width direction is larger than that of the limiting rib 5 in the width direction. Simultaneously, the dimension of the placement hole 4 in the width direction is larger than that of the mounting portion 21 in the width direction. The dimension of the mounting space 11 in the width direction is larger than that of the connecting portion 22 in the width direction, so that the connector 2 has room to move in the width direction. The difference in width between the limiting groove 6 and the limiting rib 5 is smaller than the difference in width between the placement hole 4 and the mounting portion 21. In the figure, the X direction represents the width direction; the Y direction represents the length direction; and the Z direction represents the thickness direction.

[0048] In this embodiment, the connector 2 is rotatable and has a limiting rib 5. The fixing plate 3 has a limiting groove 6 corresponding to the position of the limiting rib 5. The adjustment range of the connector 2 is limited by the positional relationship between the limiting rib 5 and the limiting groove 6, so that the mounting part 21 will not frequently contact the edge of the placement hole 4, causing wear and improving the service life of the mounting base. The limiting groove 6 has a second limiting part 9, which is used to control the rotation angle of the limiting rib 5 within the limiting groove 6, so that the rotation angle of the connector 2 is between -β and +β, where β≤45°, to improve the alignment efficiency between the connector 2 and the connecting part.
