Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically to a charging gun lock actuator and an electric vehicle. Background Technology

[0002] In existing charging technologies, when a charging dock has multiple charging ports, such as both DC and AC charging ports, different charging guns can be used for charging. Current solutions all use multiple drive devices to control the locking connection between the multiple charging ports and the charging guns. Each drive device drives a corresponding locking lever to lock the charging gun onto the corresponding charging dock for charging. This approach suffers from problems such as a large number of drive device parts and high manufacturing costs.

[0003] Therefore, there is an urgent need in the field of new energy vehicle technology for a charging gun lock actuator that can use a single drive device to simultaneously control multiple locking rods to lock the charging gun, overcoming the shortcomings of existing technologies and solving problems such as the large number of drive device parts and high manufacturing costs.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] The following is for reference. Figures 1-4 The implementation of the charging gun lock actuator proposed in the embodiments of this utility model will be described in detail.

[0032] The charging gun lock actuator according to an embodiment of the present utility model includes:

[0033] Housing 1 defines the installation space;

[0034] A rotating shaft 2 is rotatably mounted on the outer casing 1;

[0035] The connector 3 is located in the installation space and is connected to the rotating shaft 2 so as to rotate synchronously with the rotating shaft 2. The connector is provided with a first sliding groove 31 and a second sliding groove 32.

[0036] The first locking rod 4 is movably inserted through the outer casing 1, and the first locking rod 4 is slidably connected to the first sliding groove 31;

[0037] The second locking rod 5 is movably installed in the outer casing 1, and the second locking rod 5 is slidably connected to the second sliding groove 32;

[0038] When the connector 3 rotates, it can drive the first locking rod 4 and the second locking rod 5 to move synchronously to lock and unlock the DC charging station 71 and the AC charging station 72 between the charging base 7 and the charging gun.

[0039] In other words, the rotating shaft 2 is rotatably inserted through the outer shell 1, and the output end of the rotating shaft 2 is located within the installation space. The connecting piece 3 is installed at the output end of the rotating shaft 2. The first locking rod 4 and the second locking rod 5 are slidably connected to the first sliding groove 31 and the second sliding groove 32 in a one-to-one correspondence. This allows the connecting piece 3 to drive the first sliding groove 31 and the second sliding groove 32 to rotate around the rotating shaft 2 when the rotating shaft 2 rotates. When the first sliding groove 31 and the second sliding groove 32 rotate, the first locking rod 4 and the second locking rod 5 move closer to or further away from the rotating shaft 2 in the radial direction of the rotating shaft 2. Due to the restrictive effect of the first locking rod 4 and the second locking rod 5 being inserted through the outer shell 1, the first locking rod 4 and the second locking rod 5 form a synchronous telescopic movement, thereby realizing the synchronous locking and unlocking of the AC charging station 72 and the DC charging station 71 between the charging gun and the charging base 7. The rotating shaft 2 can be driven by a motor or manually rotated by rotating the emergency output shaft. The extension and retraction directions of the locking part of the first locking rod 4 and the locking part of the second locking rod 5 can be set according to the specific distribution of the DC charging station 71 and the AC charging station 72. The charging gun lock actuator can be installed on the charging seat 7 of the tram or on the charging gun of the charging pile.

[0040] Therefore, by using the two sliding grooves on the connector 3 in conjunction with the two locking rods, the rotational motion of the connector 3 can be converted into the linear extension and retraction motion of the two locking rods, thereby achieving synchronous locking and unlocking of the DC charging station 71 and the AC charging station 72. This charging gun lock actuator has a simple structure, reduces the number of sub-parts, and effectively reduces manufacturing costs.

[0041] Optionally, one end of the first slide groove 31 and the second slide groove 32 is positioned close to the rotating shaft 2, while the other end is positioned away from the rotating shaft 2. Understandably, this configuration allows the first slide groove 31 and the second slide groove 32 to rotate synchronously along the rotating shaft 2 when the rotating shaft 2 rotates. The distance difference between the two ends of the slide grooves and the center of the rotating shaft 2 controls the extension and retraction strokes of the first locking rod 4 and the second locking rod 5, thereby driving the extension and retraction of the first locking rod 4 and the second locking rod 5. The first slide groove 31 and the second slide groove 320 can be straight grooves or arc-shaped grooves, preferably arc-shaped grooves closed at both ends. This allows for the control of the extreme positions of the extension and retraction of the first locking rod 4 and the second locking rod 5, ensuring the accuracy of locking and unlocking. Simultaneously, the arc-shaped groove configuration ensures the smooth sliding of the first locking rod 4 and the second locking rod 5, thus guaranteeing the smooth extension and retraction of the first locking rod 4 and the second locking rod 5.

[0042] Optionally, the locking portion of the first locking rod 4 and the locking portion of the second locking rod 5 are arranged at an angle. Understandably, the locking portions of the first locking rod 4 and the second locking rod 5 are located at their free ends, and the angle between them matches the existing positional distribution of the DC charging station 71 and the AC charging station 72, thereby facilitating the synchronous locking or unlocking of the DC charging station 71 and the AC charging station 72 between the charging gun and the charging base 7. The angle between the locking portions of the first locking rod 4 and the second locking rod 5 can be 90°.

[0043] Furthermore, the first locking rod 4 is a straight rod, and the second locking rod 5 is a bent rod. Understandably, the first locking rod 4 is used to lock the AC charging station 72, and the second locking rod 5 is used to lock the DC charging station 71. The straight rod design of the first locking rod 4 facilitates matching the locking of existing AC charging guns and charging bases 7. The bent design of the second locking rod 5 allows the locking part of the second locking rod 5 to be located on the side of the DC charging gun and charging base 7, thus facilitating matching the locking of existing AC charging guns and charging bases 7. The second locking rod 5 can be Z-shaped.

[0044] Optionally, each end of the first locking rod 4 and the second locking rod 5 is provided with a sliding pin 6, and the two sliding pins 6 are slidably engaged in the first sliding groove 31 and the second sliding groove 32 in a one-to-one correspondence. Understandably, the use of sliding pins 6 avoids the increase in manufacturing costs caused by integral machining, and also facilitates the replacement of sliding pins 6 when they wear out. The sliding pin 6 can be cylindrical, with connecting holes on the first locking rod 4 and the second locking rod 5, and a connecting post on the sliding pin 6 inserted into the connecting hole.

[0045] Optionally, the outer casing 1 defines a limiting groove 111, which abuts against the connector 3 to limit the rotation range of the connector 3. Understandably, by setting the limiting groove 111, the rotation range of the connector 3 can be limited, thereby further limiting the extension and retraction stroke of the first locking rod 4 and the second locking rod 5, facilitating precise locking of the charging gun and the charging base 7.

[0046] Optionally, the outer casing 1 includes a first casing 11 and a second casing 12, which are detachably connected to jointly form an installation space. The first casing 11 has a first sliding channel 112 and a second sliding channel 113, and the first locking rod 4 and the second locking rod 5 are correspondingly inserted into the first sliding channel 112 and the second sliding channel 113. Understandably, the arrangement of the first casing 11 and the second casing 12 facilitates the installation of the connector 3, the first locking rod 4, the second locking rod 5, and the rotating shaft 2. The arrangement of the first sliding channel 112 and the second sliding channel 113 better restricts the sliding of the first locking rod 4 and the second locking rod 5 within the first sliding channel 112 and the second sliding channel 113, thereby preventing the first locking rod 4 and the second locking rod 5 from swaying due to the rotation of the connector 3, and facilitating precise locking of the first locking rod 4 and the second locking rod 5. Sealing elements can be provided between the first casing 11 and the second casing 12, between the first locking rod 4 and the second locking rod 5 and the first sliding channel 112 and the second sliding channel 113, and between the rotating shaft 2 and the first casing 11.

[0047] Furthermore, the first sliding channel 112 and the second sliding channel 113 extend outward toward the installation space. Understandably, by extending the first sliding channel 112 and the second sliding channel 113 outward toward the installation space, the axial contact surface between the first housing 11 and the first locking rod 4 and the second locking rod 5 can be increased, thereby preventing the first locking rod 4 and the second locking rod 5 from swaying due to rotation of the connecting member 3, and facilitating precise locking of the first locking rod 4 and the second locking rod 5. The extension length of the first sliding channel 112 can be longer than the extension length of the second sliding channel 113.

[0048] In addition, this utility model also proposes a tram, which includes a charging base 7, and the charging base 7 includes the aforementioned charging gun lock actuator. Understandably, by setting the charging gun lock actuator in this tram, the charging gun and the tram's charging base 7 can be stably locked and unlocked simultaneously at the DC charging station 71 and AC charging station 72, while reducing the number of sub-parts, saving costs, and making the overall charging gun structure more compact and space-saving. The charging gun lock actuator can be installed inside the charging base 7 of the tram, with a through hole connecting the DC charging station 71 and AC charging station 72. When the locking parts of the first locking rod 4 and the second locking rod 5 extend and retract, they pass through the through hole into the DC charging station 71 and AC charging station 72 to lock the charging base 7 and the charging gun. When they exit the DC charging station 71 and AC charging station 72, they unlock the charging base 7 and the charging gun.
