Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a stabilization mechanism for a DC charging pile power metering and verification device. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. Users can use a specific charging card to swipe on the human-machine interface provided by the charging pile to perform operations such as selecting the charging method, charging time, and printing cost data. The charging pile display screen can display data such as charging amount, cost, and charging time.

[0003] In existing technologies, DC charging piles have internal power meters installed to monitor the amount of electricity used to charge electric vehicles, allowing users to easily check the usage. However, the power meter has a relatively delicate structure, and when a user pushes the electric vehicle to the charging pile, it is easy to bump into the pile. The impact causes the charging pile to shake, which can easily damage the power meter. The existing stabilization mechanisms for protecting the power meter are relatively simple and have poor protection performance. Furthermore, the surface of the power meter is prone to dust accumulation during long-term use, which affects the heat dissipation of the device and reduces its service life.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Example 1:

[0031] Reference Figure 1-7A stabilizing mechanism for a DC charging pile power metering verification device includes a charging pile housing 1, an installation frame 2 inside the charging pile housing 1, a power meter 3 inside the installation frame 2, a partition plate 4 fixed to the inner wall of the charging pile housing 1, a buffer assembly 5 for buffering and shock absorption on the partition plate 4, a power assembly 6 for providing power on the buffer assembly 5, a cleaning assembly 7 for cleaning dust from the surface of the power meter 3 linked to the power assembly 6, and an anti-sway assembly 8 inside the charging pile housing 1 for preventing the power meter 3 from shaking violently.

[0032] In this invention, during use, the operator pre-installs the power meter 3 on the mounting frame 2, then connects the wire of the power meter 3 through the wiring port 11 to the charging plug, thus facilitating the measurement of the power of the user's electric vehicle and displaying the measured data in real time on the display window 10. When the charging pile housing 1 is impacted by external forces, the buffer component 5 on the partition plate 4 effectively buffers and dissipates the force generated by the impact on the charging pile housing 1, thereby providing good protection for the power meter 3 inside the charging pile housing 1 and preventing damage to the power meter 3 from the impact. The protection effect is good and the practicality is strong. The power meter 3 installed inside the charging pile housing 1 generates heat due to long-term operation. Dust entering the charging pile housing 1 adheres to the surface of the power meter 3, affecting its heat dissipation. During the operation of the buffer component 5... During the process, as the charging pile housing 1 shakes synchronously, the power component 6, which is installed on the buffer component 5, has a connecting plate 607 that contacts the inner wall of the charging pile housing 1 and is subjected to a squeezing force. This squeezing force drives the power component 6 to run, compressing the air inside the connecting cylinder 601. Through the cooperation of the power component 6 and the cleaning component 7, the compressed air is sprayed out with multiple nozzles 704 installed on the cleaning component 7, which facilitates the blowing off and cleaning of dust adhering to the surface of the power meter 3. This effectively improves the heat dissipation effect of the power meter 3. At the same time, when the charging pile housing 1 is impacted, the anti-sway component 8 installed inside the charging pile housing 1 can buffer and dampen the shaking caused by the impact, effectively reducing the shaking frequency of the charging pile housing 1, improving the stability of the power meter 3, preventing damage to the power meter 3 due to impact, and thus extending the service life of the power meter 3.

[0033] Example 2:

[0034] Reference Figure 1-7A stabilizing mechanism for a DC charging pile energy metering verification device includes a charging pile housing 1, an installation frame 2 inside the charging pile housing 1, an energy meter 3 inside the installation frame 2, a partition plate 4 fixed to the inner wall of the charging pile housing 1, a buffer assembly 5 for shock absorption on the partition plate 4, a power assembly 6 for providing power on the buffer assembly 5, a cleaning assembly 7 for cleaning dust from the surface of the energy meter 3 linked to the power assembly 6, and an anti-sway assembly 8 inside the charging pile housing 1 to prevent the energy meter 3 from shaking violently. The buffer assembly 5 includes a first T-shaped groove 501 formed on the top surface of the partition plate 4. The first T-shaped slider 502 is internally slidably connected to the first T-shaped slider 502. Both ends of the first T-shaped slider 502 are fixed with first buffer springs 503. The ends of the first buffer springs 503 are fixedly connected to the first T-shaped slide groove 501. The top of the first T-shaped slider 502 is fixed with a movable plate 504. The top surface of the movable plate 504 is provided with a second T-shaped slide groove 505. The second T-shaped slider 506 is slidably connected inside the second T-shaped slide groove 505. Both ends of the second T-shaped slider 506 are fixed with second buffer springs 507. One end of the second buffer spring 507 is fixedly connected to the second T-shaped slide groove 505. The top of the second T-shaped slide groove 505 is fixedly connected to the mounting frame 2.

[0035] In this invention, when the charging pile housing 1 is impacted in the left-right direction, the impact force causes the partition plate 4 installed inside the charging pile housing 1 to shake synchronously. The second T-shaped slider 506 on the buffer assembly 5 slides inside the second T-shaped groove 505, and the second buffer spring 507 set inside the second T-shaped groove 505 can buffer and deflect the force generated by the left-right shaking, thereby providing good protection for the power meter 3 installed above the buffer assembly 5. Considering the special location of the charging pile installation, when some users push the electric vehicle, it may cause collisions with the front and rear surfaces of the charging pile housing 1. At this time, the partition plate 4 shakes back and forth, and the first T-shaped slider 502 slides back and forth inside the first T-shaped groove 501. The first buffer spring 503 set inside the first T-shaped groove 501 can buffer and deflect the force generated by the back-and-forth shaking, protecting the power meter 3 installed on it, effectively improving the protection effect of the power meter 3, and making it convenient to use.

[0036] Example 3:

[0037] Reference Figure 1-7A stabilizing mechanism for a DC charging pile energy metering verification device includes a charging pile housing 1, an installation frame 2 inside the charging pile housing 1, an energy meter 3 inside the installation frame 2, a partition plate 4 fixed to the inner wall of the charging pile housing 1, a buffer assembly 5 for shock absorption on the partition plate 4, a power assembly 6 for providing power on the buffer assembly 5, and a cleaning assembly 7 for cleaning dust from the surface of the energy meter 3 linked to the power assembly 6. The charging pile housing 1 also includes a mechanism to prevent the energy meter 3 from shaking violently. The anti-sway component 8 and the buffer component 5 include a first T-shaped groove 501 formed on the top surface of the partition plate 4, a first T-shaped slider 502 slidably connected inside the first T-shaped groove 501, a first buffer spring 503 fixed at both ends of the first T-shaped slider 502, the ends of the first buffer springs 503 fixedly connected inside the first T-shaped groove 501, a movable plate 504 fixed on the top of the first T-shaped slider 502, a second T-shaped groove 505 formed on the top surface of the movable plate 504, and a second T-shaped groove 505 slidably connected inside the second T-shaped groove 505. A second T-shaped slider 506 is provided, and a second buffer spring 507 is fixed to both ends of the second T-shaped slider 506. One end of the second buffer spring 507 is fixedly connected to the second T-shaped slide groove 505. The top of the second T-shaped slide groove 505 is fixedly connected to the mounting frame 2. A connecting cylinder 601 is fixed to one side surface of the movable plate 504. A return spring 602 is fixed inside the connecting cylinder 601. A moving block 603 is fixed to the end of the return spring 602. A limit block 604 is fixed to the surface of the moving block 603. The limit block 604 is slidably connected to the limit. Inside the positioning groove 605, the limiting groove 605 is formed on the inner wall of the connecting cylinder 601. A pressing rod 606 is fixed on one side of the moving block 603. The pressing rod 606 slides through the connecting cylinder 601. A connecting plate 607 is fixed at the end of the pressing rod 606. The connecting plate 607 is in contact with the inner wall of the charging pile housing 1. An air supply pipe 701 is fixed on the surface of the connecting cylinder 601. A fixing block 702 is fixed on the surface of the air supply pipe 701. A connecting plate 703 is fixed at the end of the air supply pipe 701. A nozzle 704 is fixed on the surface of the connecting plate 703.

[0038] In this invention, when the front and rear surfaces of the charging pile housing 1 are impacted, the buffer assembly 5 operates accordingly. A connecting cylinder 601 is fixed to one side of the movable plate 504 on the buffer assembly 5. The force generated by the shaking causes the connecting disc 607 on the power assembly 6 to contact the inner wall of the charging pile housing 1. The resulting squeezing force causes the squeezing rod 606, located on one side of the connecting disc 607, to slide inside the connecting cylinder 601. The moving block 603 at one end of the squeezing rod 606 slides inside the connecting cylinder 601, squeezing the air inside. The resulting airflow is transported out through the air pipe 701, passes through the connecting plate 703, and is then sprayed out by multiple nozzles 704, blowing off dust adhering to the surface of the power meter 3. This improves the cleaning effect, enhances the heat dissipation of the power meter 3, and reduces the occurrence of power meter malfunctions. The reset spring 602 installed inside the connecting cylinder 601 provides elastic reset, squeezing the moving block 603 back to its original position for easy use.

[0039] Example 4:

[0040] Reference Figure 1-7 A stabilizing mechanism for a DC charging pile energy metering verification device includes a charging pile housing 1, an installation frame 2 inside the charging pile housing 1, an energy meter 3 inside the installation frame 2, a partition plate 4 fixed to the inner wall of the charging pile housing 1, a buffer assembly 5 for shock absorption on the partition plate 4, a power assembly 6 for providing power on the buffer assembly 5, and a cleaning assembly 7 for cleaning dust from the surface of the energy meter 3 linked to the power assembly 6. The charging pile housing 1 also includes a mechanism for preventing the energy meter from... 3. Anti-sway component 8 for violent shaking. The anti-sway component 8 includes a mounting block 801 fixed to the inner wall of the top of the charging pile housing 1. A hanging ring 802 is fixed to the bottom of the mounting block 801.

A limit plate 807 is threadedly connected to the end of the connecting rod 806. A weight block 808 is sleeved on the surface of the connecting rod 806.

[0041] In this invention, when the charging pile housing 1 is impacted, it shakes. When the charging pile housing 1 shakes, it causes the swing rod 804 on the anti-sway component 8 to shake. According to the installation requirements, the operator can manually rotate the limit plate 807 to remove it. Then, an appropriate amount of weight block 808 is added and fitted onto the surface of the connecting rod 806 to increase the weight, improve the damping effect on the charging pile housing 1, reduce the shaking frequency of the charging pile housing 1, and maintain the stability of the charging pile housing 1. This further protects the power meter 3 installed inside the charging pile housing 1 and prevents damage to the power meter 3 caused by the device impacting the charging pile housing 1.
