Description

Technical Field

[0001] The utility model relates to the industry field of electronic locks for charging sockets of new energy vehicles, and in particular to a detection structure for electronic locks for charging sockets of new energy vehicles. Background Art

[0002] With the continuous progress and development of new energy technology in my country, new energy vehicles have developed rapidly.

[0003] New energy vehicles are usually charged with charging piles. In order to shorten the charging time, most of them use DC high voltage and high current. Charging is done outdoors. There are still many non-professionals in the operation. Based on these characteristics, high safety and adaptability are required. The emergence of electronic locks can effectively solve this problem. At the same time, electronic locks are also a safety guarantee for electric vehicle charging.

[0004] Existing electronic locks usually use micro switches, which can only feedback two signals: extension and retraction of the lock rod. They are not compatible with more signal feedbacks. There are only two types of signal feedback for the vehicle body, and they are not accurate. The vehicle cannot accurately determine the locking status.

[0005] The existing patent application number is CN201620387933.5, which is a car charging socket, including a push rod, a pressure rod, and a micro switch. The pressure rod is fixedly installed on the push rod, so that when the push rod moves, the pressure rod also moves synchronously with the push rod. When the charging gun is not inserted into place, the stroke of the push rod is insufficient to make the pressure rod contact with the micro switch, so that the system cannot receive the locking signal fed back by the micro switch, and the system will not supply power to the charging terminal; when the charging gun is inserted into place, the stroke of the push rod allows the pressure rod to contact the micro switch, thereby turning on the micro switch, so that the system can receive the feedback locking signal, thereby controlling the power supply of the charging terminal. This solution can only handle two signals: whether the charging gun is inserted into place, and its practicality is low. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] Embodiment 1

[0033] The utility model provides a detection structure for an electronic lock of a new energy vehicle charging socket, such as Figures 1 to 7 As shown, it includes a sliding seat 1 and a PCB board 2. The sliding seat 1 is provided with a spring piece 3 and a locking rod 4.

[0034] In this embodiment, a signal detection sheet 21 is provided on the PCB board 2, and the signal detection sheet 21 is electrically connected to the in-vehicle control system. In this embodiment, a wire lead sheet 22 is provided on the PCB board 2, and the signal detection sheet 21 is electrically connected to the wire lead sheet 22. The PCB board 2 is electrically connected to the in-vehicle control system through the wire lead sheet 22. Figure 6 As shown, the signal detection pieces 21 include two, and the two signal detection pieces 21 are electrically connected to two wire lead-out pieces 22 respectively. The PCB board 2 leads out two wires through the wire lead-out pieces 22 and is electrically connected to the in-vehicle control system. The feedback vehicle body monitoring mode is the extended state and the retracted state and various resistance value detections, thereby realizing real-time monitoring of the state of the locking rod 4, and by changing the resistance value of the signal detection piece 21, accurate detection of the locking rod 4 can be achieved.

[0035] like Figure 3 As shown, the spring piece 3 includes a fixed part 31 and a movable part 32. The spring piece 3 is fixedly matched with the sliding seat 1 through the fixed part 31, and the movable part 32 is movably abutted against the signal detection piece 21. In this embodiment, the movable part 32 includes two groups. The two groups of movable parts 32 correspond to the two signal detection pieces 21 one by one, respectively. The two signal detection pieces 21 are signal detection piece 1 211 and signal detection piece 212 respectively. The signal detection piece 1 211 and the signal detection piece 212 are parallel to each other. The two groups of movable parts 32 are movable part 1 321 and movable part 2 322 respectively. The signal detection piece 1 211 is set as a long strip structure, and the signal detection piece 212 is set as a short strip structure. The movable part 1 321 always abuts against the signal detection piece 1 211, and the movable part 2 322 moves with the sliding seat 1 to abut against or separate from the signal detection piece 212.

[0036] In this embodiment, the main function of the signal detection piece 212 is to monitor the extension state and retraction state of the locking rod 4. When the locking rod 4 is extended, the movable part 322 and the signal detection piece 212 are abutted against each other, triggering a corresponding electrical signal. When the locking rod 4 is retracted, the movable part 322 is separated from the signal detection piece 212, and the electrical signal changes accordingly. The signal detection piece 1 211 is mainly used for resistance detection. These electrical signals are transmitted to the in-vehicle control system through the wire lead-out piece 22, thereby realizing real-time monitoring of the state of the locking rod 4.

[0037] In this embodiment, the spring piece 3 further includes a connecting portion 33, and the two ends of the connecting portion 33 are respectively fixedly connected to the fixed portion 31 and the movable portion 32, and the mounting groove 11 (described below) includes a movable opening 111 for the movable portion 32 to extend out, and the movable portion 32 extends out of the movable opening 111, and the end of the movable portion 32 away from the connecting portion 33 is inclined toward the side of the PCB board 2. The connecting portion 33 serves as a bridge between the fixed portion 31 and the movable portion 32, ensuring a stable connection between the two, and allowing the movable portion 32 to elastically deform relative to the fixed portion 31. The movable opening 111 allows the movable portion 32 of the spring piece 3 to extend from the mounting groove 11 and dynamically interact with the signal detection piece 21. The movable portion 32 is an inclined structure, so that the movable portion 32 can more accurately trigger the signal change when it abuts against the signal detection piece 21, thereby improving the accuracy and sensitivity of the detection. When the sliding seat 1 moves, the movable portion 32 will produce corresponding elastic deformation according to its inclination angle, and produce an action of abutting or separating with the signal detection piece 21, thereby triggering the signal detection piece 21 to produce an electrical signal change.

[0038] In this embodiment, a buffer section 323 is provided at one end of the movable portion 32 away from the connecting portion 33. The buffer section 323 is configured as an arc structure, and the arc curve bulges toward the side of the PCB board 2, which can effectively reduce the impact force and friction force of the movable portion 32 when interacting with the PCB board 2 or other contact surfaces, and can effectively disperse the force and reduce single-point pressure, thereby improving the stability and durability of the structure and increasing the service life of the movable portion 32.

[0039] In this embodiment, a mounting groove 11 is provided on the sliding seat 1, and the spring piece 3 is engaged with the mounting groove 11. A limiting block 112 is provided on the side wall of the mounting groove 11. The limiting block 112 and the bottom end surface of the mounting groove 11 are provided with a first limiting groove 113, and the fixing portion 31 is engaged with the first limiting groove 113. The mounting groove 11 is used to install the spring piece 3. The first limiting groove 113 is used to further limit the position of the spring piece 3 in the mounting groove 11 to prevent it from moving or rotating during use, thereby ensuring the stability of the spring piece 3 in the mounting groove 11. It should be noted that the shape and size of the mounting groove 11 should match the fixing portion 31 of the spring piece 3 to ensure the accuracy and stability of the engagement. In this embodiment, the limiting block 112 includes two groups, and the two groups of limiting blocks 112 are respectively located on the opposite side walls of the mounting groove 11.

[0040] In this embodiment, the mounting groove 11 includes a mounting opening 114 for mounting the spring piece 3, and the spring piece 3 is inserted into the mounting groove 11 through the mounting opening 114. A buffer portion 1121 is provided on the side of the limiting block 112 facing the mounting opening 114. The side end surface of the buffer portion 1121 facing the first limiting groove 113 and the side end surface of the buffer portion 1121 facing the movable portion 32 are both set as inclined surfaces. When the spring piece 3 is installed in the mounting groove 11, the limiting block 112 is located between the movable portion 32 and the mounting portion. The side end surface of the buffer portion 1121 facing the first limiting groove 113 is set as an inclined surface to facilitate the introduction of the fixed portion 31 into the first limiting groove 113, which can effectively reduce the impact force of the spring piece 3 during the installation process. The side end surface of the buffer portion 1121 facing the movable portion 32 is set as an inclined surface to facilitate the abutment of the movable portion 32 with the limiting block 112, which can effectively prevent the movable portion 32 from bending.

[0041] The fixing portion 31 is provided with a limiting member 311, and the limiting member 311 is configured to be an inclined structure inclined toward the fixing portion 11, and the limiting member 311 is abutted against the side wall of the second limiting member 115. In the limiting member 311, an end of the limiting member 311 facing the connecting portion 33 is a movable end 3111, and an end of the limiting member 311 away from the connecting portion 33 is a fixed end 3112. The limiting member 311 is configured to be an inclined structure in which the movable end 3111 is inclined downward toward the fixing portion 11. When the spring piece 3 is inserted into the fixing portion 11, the limiting member 311 is pressed, and when the limiting member 311 moves to the second limiting member 115, it pops up. At this time, the movable end 3111 is abutted against the side wall of the second limiting member 115, which can further fix and stabilize the position of the spring piece 3 in the fixing portion 11.

[0042] In this embodiment, a fixing block 116 is provided on the side wall of the mounting groove 11, and a snap-fitting groove 312 is provided on the fixing portion 31. The snap-fitting groove 312 is snap-fitted with the fixing block 116, and one end surface of the fixing block 116 facing the spring sheet 3 abuts against the snap-fitting groove 312, thereby ensuring that the spring sheet 3 is accurately installed in the mounting groove 11, and further preventing the spring sheet 3 from moving or rotating during use. In this embodiment, the fixing block 116 is located on the side wall of the mounting groove 11 opposite to the mounting opening 114.

[0043] In this embodiment, a through groove 12 is provided on the sliding seat 1, and the through groove 12 passes through the sliding seat 1 and is communicated with the first limiting groove 113. The cooperation between the first limiting groove 113 and the fixing portion 31 of the spring piece 3 can be directly observed from the outside of the sliding seat 1. The staff can directly access the first limiting groove 113 through the through groove 12, so as to conveniently adjust or replace the spring piece 3. In other embodiments, a seal can be added to the through groove 12 or other protective measures can be used to ensure that the interior of the sliding seat 1 will not be affected by the external environment.

[0044] In this embodiment, the fixing portion 31 and the central axis of the locking rod 4 are parallel to each other, ensuring the coordination and consistency between the spring piece 3 and the locking rod 4. The locking rod 4 is linked with the sliding seat 1 to ensure that the detection structure detects the extended state and retracted state of the locking rod 4, making the entire system more stable and reliable.

[0045] In this embodiment, a fixing groove 13 for installing the locking rod 4 is provided on the sliding seat 1, and the locking rod 4 is engaged with the fixing groove 13. A fixing pin 41 is provided on the locking rod 4, and the fixing pin 41 passes through the locking rod 4. The fixing pin 41 passes through the sliding seat 1 and is embedded in the fixing groove 13, thereby realizing a fixed connection between the locking rod 4 and the sliding seat 1, and ensuring the stability of the locking rod 4 installed on the sliding seat 1.

[0046] The utility model provides a detection structure for an electronic lock of a charging socket of a new energy vehicle. Through the abutment cooperation between the spring piece 3 and the PCB board 2, various positions can be detected according to the sliding of the sliding seat 1 and various signal feedbacks can be provided, so that the vehicle can accurately judge the locking situation. Through the precise abutment cooperation between the movable part 32 and the signal detection sheet 21, the detection structure can monitor all states such as the extension and retraction of the lock rod 4 and the semi-retracted position, and accurately measure the running distance of the lock rod 4. The detection structure allows the user to add any size of resistance feedback according to the needs. This flexibility enables the detection structure to adapt to the requirements of different vehicles and charging systems, and provides a wide range of compatibility. By accurately monitoring the state and running distance of the lock rod 4, the detection structure can ensure that the charging socket remains safe in the locked state, helps to prevent safety accidents caused by misoperation or external interference, and can reduce charging interruptions or failures caused by misjudgment or delays, thereby improving the user experience and enabling the user to complete the charging process faster and more reliably.

Figure 7 As shown, the signal detection piece 21 also includes a signal detection piece three 213. The signal detection piece three 213 and the signal detection piece one 211 are parallel to each other, and the signal detection piece three 213 is located on one side of the signal detection piece two 212. There is a gap between the signal detection piece three 213 and the signal detection piece two 212. The movable part 32 moves with the sliding seat 1 to contact or separate from the signal detection piece three 213. The feedback vehicle body monitoring mode is the extended state, the retracted state, any intermediate state and various resistance detection.
