Description

Technical Field

[0001] This utility model relates to the field of sensing equipment technology, and in particular to a charging pile gun head sensing device. Background Technology

[0002] The charging gun (also known as a charging plug or charging gun) is a key connection component for energy transfer between an electric vehicle and a charging station, acting as an "electrical socket and plug." It is responsible for safely and efficiently delivering electrical energy from the charging station to the vehicle's battery. Its design must balance conductivity, safety, durability, and compatibility. It is a core component in the charging system that directly interacts with the user. The charging gun sensor is a device used to detect the status of the charging gun, enabling monitoring of parameters such as insertion, removal, reset, and temperature, ensuring the safety and reliability of the charging process. Common examples include temperature sensors and current sensors.

[0003] The sensors in existing charging station guns all require connection lines during use. Since the sensor and the connection line are usually integrated, when the sensor is damaged, the connection line needs to be cut to separate it from the sensor. Then, the outer sheath of the connection line needs to be peeled off before it can be connected to a new sensor. This makes it cumbersome and labor-intensive to replace the sensor, affecting the convenience and efficiency of sensor maintenance. Utility Model Content

[0004] The technical problem this invention aims to solve is that when a sensor is damaged, personnel need to cut the connecting wire to separate it from the sensor, and then peel off the outer sheath of the connecting wire before connecting it to a new sensor. This makes sensor replacement cumbersome and labor-intensive, affecting the convenience and efficiency of sensor maintenance.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a charging gun head sensing device, comprising: a sensor disposed inside the charging gun head body, wherein the charging gun head body is connected to the charging pile body via a cable, and the sensor is connected to the charging pile body via a connecting line for monitoring and sensing data such as the temperature of the charging gun head body; a connecting device, wherein the connecting device is disposed between the sensor and the connecting line, wherein the connecting device includes a connecting post and a cylinder, wherein the surface of the connecting post is engaged with the inner wall of the cylinder, and the connecting post and the cylinder are assembled by a snap-fit ​​assembly for quick assembly and disassembly of the sensor and the connecting line.

[0006] The effect achieved by the above components is that by setting up a connecting device, personnel can easily assemble and disassemble the connecting wire and the sensor through the connecting column and the cylinder, reducing the operation steps and time required when replacing the sensor, and improving the convenience and efficiency of maintaining and replacing the sensor.

[0007] Preferably, the snap-fit ​​assembly includes: an L-shaped groove, the L-shaped groove being formed inside the cylinder, wherein the inner wall of the long arm end of the L-shaped groove is connected to the edge of the cylinder; and a snap-fit ​​block, the snap-fit ​​block being fixed to the connecting post, wherein the surface size and shape of the snap-fit ​​block are adapted to the size and shape of the inner wall of the L-shaped groove.

[0008] The aforementioned components achieve the following effects: By setting up an L-shaped groove and a locking block, when personnel need to assemble the connecting column with the cylinder, they can manually move the connecting column, causing it to move the locking block. When the connecting column moves to the position where it is fully inserted into the cylinder, the locking block is inserted into the L-shaped groove along the long arm side. At this point, the connecting column can be manually rotated, causing it to rotate the locking block along the L-shaped groove. When the locking block rotates to the position where it is inserted into the short arm side of the L-shaped groove, it is blocked and limited by the height difference between the cylinder and the inner wall of the L-shaped groove, thus completing the assembly and fixation between the connecting column and the cylinder. This achieves rapid assembly between the sensor and the connecting wire, and allows for convenient disassembly afterward, improving the ease and efficiency of assembling and disassembling the sensor and the connecting wire.

[0009] Preferably, multiple rubber strips are fixed to the side of the locking block away from the connecting column, and multiple circular grooves are formed on the inner wall of the L-shaped groove, wherein the rubber strips are placed inside the circular grooves to increase the friction and resistance between the locking block and the inner wall of the L-shaped groove.

[0010] The effect achieved by the above components is as follows: by setting the circular groove and the rubber strip, the rubber strip can enter the L-shaped groove along with the locking block, and by embedding it into the circular groove, the friction and resistance between the locking block and the inner wall of the L-shaped groove are increased, further improving the stability of the locking block when it is locked into the L-shaped groove.

[0011] Preferably, a plurality of anti-slip strips are fixedly connected to the connecting column, and the plurality of anti-slip strips are arranged at equal intervals.

[0012] The effect achieved by the above components is that by setting anti-slip strips, the friction between the hand and the surface of the connecting column can be increased, reducing the chance of slipping when manually rotating the connecting column.

[0013] Preferably, the snap-fit ​​assembly may further include: a slot, the slot being formed inside the cylinder; and an insert block, the insert block being fixedly connected to the connecting post, wherein the insert block has a beveled edge on one side of the cylinder.

[0014] The effect achieved by the above components is as follows: by setting the embedding block and the slot, the connecting column is first moved manually to drive the embedding block to move. When the connecting column moves to the position of being inserted into the cylinder, the beveled part of the embedding block contacts the surface of the cylinder. When the connecting column moves to the position of being fully inserted into the cylinder, the embedding block is pushed into the cylinder and embedded in the slot. The height difference between the inner wall of the slot and the cylinder is used to intercept and limit the embedding block, thereby completing the assembly and fixing between the connecting column and the cylinder and improving the connection stability between the connecting column and the cylinder.

[0015] Preferably, the inner wall of the cylinder edge is provided with an oblique angle, wherein the oblique angle provided on the cylinder is adapted to the slope of the slope surface on the embedded block.

[0016] The effect achieved by the above components is that by opening an angle at the edge of the cylinder, the angle can match the beveled surface on the insert block, increasing the smoothness of the insert block entering the cylinder and improving the snap-fit ​​efficiency.

[0017] Preferably, the snap-fit ​​assembly may further include: a positioning groove formed on the connecting post; and an elastic sheet fixed to the inner side of the cylinder, wherein the elastic sheet is made of spring steel and has an overall trapezoidal shape, and wherein the elastic sheet limits the position of the connecting post by being embedded inside the positioning groove.

[0018] The effect achieved by the above components is as follows: by setting the positioning groove and the elastic plate, the connecting column is first moved manually. When the connecting column moves to the position of being inserted into the cylinder, the surface of the connecting column is pressed against the sloped side of the elastic plate, causing the elastic plate to deform under the pressure of the connecting column. When the connecting column moves to the position of being fully inserted into the cylinder, the positioning groove moves to the position corresponding to the elastic plate, releasing the pressure on the elastic plate. After the elastic plate loses the pressure, it resets and is locked into the positioning groove to fix the position of the connecting column, thereby completing the assembly and fixing between the connecting column and the cylinder, and further improving the ease of assembly between the connecting column and the cylinder.

[0019] Preferably, an elastic rod is fixed to the inner side of the elastic sheet, wherein the elastic rod is made of the same material as the elastic sheet.

[0020] The effect achieved by the above components is that the inner side of the elastic sheet can be supported by the elastic rod, and the elastic sheet can be assisted to rebound, thereby increasing the rebound force of the elastic sheet and improving its service life.

[0021] The beneficial effects of this utility model are:

[0022] By setting up a connection device, personnel can easily assemble and disassemble the connection wire and sensor through the connection column and cylinder, reducing the operation steps and time required when replacing sensors, and improving the convenience and efficiency of maintaining and replacing sensors.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Figure 1-6The charging gun head sensing device shown includes: a sensor 3 disposed inside the charging gun head body 2, wherein the charging gun head body 2 is connected to the charging pile body 1 via a cable, and the sensor 3 is connected to the charging pile body 1 via a connecting wire, for monitoring and sensing data such as the temperature of the charging gun head body 2; and a connecting device 4 disposed between the sensor 3 and the connecting wire, wherein the connecting device 4 includes a connecting post 41 and a cylinder 42, wherein the surface of the connecting post 41 is engaged with the inner wall of the cylinder 42, and the connecting post 41 and the cylinder 42 are assembled by a snap-fit ​​assembly, for quick disassembly and assembly of the sensor 3 and the connecting wire. By setting up the connecting device 4, personnel can easily disassemble and assemble the connecting wire and the sensor 3 through the connecting post 41 and the cylinder 42, reducing the operation steps and time required when personnel replace the sensor 3, and improving the convenience and efficiency of maintaining and replacing the sensor 3.

[0034] Figure 4-6 The shown snap-fit ​​assembly includes: an L-shaped groove 501, which is formed inside the cylinder 42, wherein the inner wall of the long arm end of the L-shaped groove 501 is connected to the edge of the cylinder 42; and a snap-fit ​​block 503, which is fixed to the connecting post 41, wherein the size and shape of the snap-fit ​​block 503 are adapted to the size and shape of the inner wall of the L-shaped groove 501. By setting the L-shaped groove 501 and the snap-fit ​​block 503, when a person needs to assemble the connecting post 41 with the cylinder 42, the connecting post 41 is manually moved, causing the connecting post 41 to move the snap-fit ​​block 503. When the connecting post 41 moves to the position where it is fully inserted into the cylinder 42, the snap-fit ​​block 503 moves. 3. Insert the connector 41 into the L-shaped groove 501 along the long arm side. Then, manually rotate the connector 41 so that the connector 41 drives the locking block 503 to rotate along the L-shaped groove 501. When the locking block 503 rotates to the position where it is inserted into the short arm side of the L-shaped groove 501, the locking block 503 enters the short arm side of the L-shaped groove 501 and is blocked and limited by the height difference between the cylinder 42 and the inner wall of the L-shaped groove 501. This completes the assembly and fixation between the connector 41 and the cylinder 42, thereby achieving rapid assembly between the sensor 3 and the connecting wire. It can also be easily disassembled later, improving the convenience and efficiency of disassembly and assembly between the sensor 3 and the connecting wire.

[0035] Figure 4-6Multiple rubber strips 504 are fixed to the side of the locking block 503 away from the connecting post 41. Multiple circular grooves 502 are opened on the inner wall of the L-shaped groove 501. The rubber strips 504 are placed inside the circular grooves 502 to increase the friction and resistance between the locking block 503 and the inner wall of the L-shaped groove 501. By setting the circular grooves 502 and the rubber strips 504, the rubber strips 504 can enter the L-shaped groove 501 together with the locking block 503. By embedding into the circular grooves 502, the friction and resistance between the locking block 503 and the inner wall of the L-shaped groove 501 are increased, further improving the stability of the locking block 503 in the L-shaped groove 501. Multiple anti-slip strips 505 are fixed to the connecting post 41. The multiple anti-slip strips 505 are arranged at equal distances. By setting the anti-slip strips 505, the friction between the hand and the surface of the connecting post 41 can be increased, reducing the possibility of slippage when manually rotating the connecting post 41.

[0036] Figure 4-6 The shown snap-fit ​​assembly can also include: a slot 511, which is formed inside the cylinder 42; and an insert block 513, which is fixedly connected to the connecting post 41. The insert block 513 has a beveled edge near the edge of the cylinder 42. By setting the insert block 513 and the slot 511, the connecting post 41 is first manually moved to move the insert block 513. When the connecting post 41 moves to the position where it is inserted into the cylinder 42, the beveled part of the insert block 513 contacts the surface of the cylinder 42. When the connecting post 41 moves to the position where it is fully inserted into the cylinder 42, the insert block 513 is pushed into the cylinder 42 and embedded. Inside the slot 511, the height difference between the inner wall of the slot 511 and the cylinder 42 is used to intercept and limit the insertion block 513, thereby completing the assembly and fixation between the connecting post 41 and the cylinder 42, improving the connection stability between the connecting post 41 and the cylinder 42. The inner wall of the edge of the cylinder 42 is provided with a chamfer 512, wherein the chamfer 512 on the cylinder 42 is adapted to the slope of the slope surface on the insertion block 513. By providing a chamfer 512 at the edge of the cylinder 42, the chamfer 512 can fit with the slope surface on the insertion block 513, increasing the smoothness of the insertion block 513 into the cylinder 42 and improving the snapping efficiency.

[0037] Figure 4-6The shown snap-fit ​​assembly can also include: a positioning groove 521, which is formed on the connecting post 41; and an elastic sheet 522, which is fixed to the inner side of the cylinder 42. The elastic sheet 522 is made of spring steel and has a trapezoidal shape. The elastic sheet 522 limits the connection post 41 by being embedded in the positioning groove 521. By setting the positioning groove 521 and the elastic sheet 522, the connecting post 41 is first manually moved. When the connecting post 41 moves to the position where it is inserted into the cylinder 42, the surface of the connecting post 41 presses against the sloped side of the elastic sheet 522, causing the elastic sheet 522 to deform under the pressure of the connecting post 41. When the connecting post 41 moves to the position where it is fully inserted into the cylinder 42... When positioned, the positioning groove 521 moves to the position corresponding to the elastic piece 522, releasing the compression on the elastic piece 522. After the elastic piece 522 loses its compressive force, it resets, allowing it to snap into the positioning groove 521 and fix the position of the connecting column 41. This completes the assembly and fixation between the connecting column 41 and the cylinder 42, further improving the ease of assembly between the connecting column 41 and the cylinder 42. An elastic rod 523 is fixedly connected to the inner side of the elastic piece 522. The elastic rod 523 is made of the same material as the elastic piece 522. By setting the elastic rod 523, the inner side of the elastic piece 522 can be supported, and the elastic piece 522 can be assisted to rebound, increasing the rebound force of the elastic piece 522 and improving its service life.

[0038] Working principle: When the charging gun head 2 is in use, the temperature sensor 3 of model PT1000 platinum resistance thermometer uses the temperature-sensitive characteristics of the material to convert the temperature of the contact part of the charging gun head 2 into a change in resistance or potential. After being converted into a voltage signal by the circuit and digitally processed, it is transmitted to the control unit. When the temperature exceeds the threshold, it will protect the charging process by limiting the current or cutting off the power. This achieves overheat monitoring and safety protection during the charging process.

[0039] Example 1: When personnel need to assemble the connecting post 41 with the cylinder 42, they manually move the connecting post 41, causing the connecting post 41 to move the locking block 503. When the connecting post 41 moves to the position where it is fully inserted into the cylinder 42, the locking block 503 is inserted into the L-shaped groove 501 along its long arm side. At this time, the connecting post 41 is manually rotated, causing the connecting post 41 to rotate the locking block 503 along the L-shaped groove 501. When the locking block 503 rotates to the short arm side of the L-shaped groove 501... When the part is in the correct position, the locking block 503 enters the short arm side of the L-shaped groove 501 and is blocked and limited by the height difference between the cylinder 42 and the inner wall of the L-shaped groove 501. At the same time, the rubber strip 504 enters the L-shaped groove 501 along with the locking block 503, and increases the friction and resistance between the locking block 503 and the inner wall of the L-shaped groove 501 by embedding it into the circular groove 502, thereby completing the assembly and fixation between the connecting column 41 and the cylinder 42, and thus achieving rapid assembly between the sensor 3 and the connecting wire.

[0040] Example 2: First, manually move the connecting post 41 to move the embedded block 513. When the connecting post 41 moves to the position where it is inserted into the cylinder 42, the beveled part of the embedded block 513 contacts the surface of the cylinder 42. When the connecting post 41 moves to the position where it is fully inserted into the cylinder 42, the embedded block 513 pushes into the cylinder 42 and is embedded in the slot 511. The height difference between the inner wall of the slot 511 and the cylinder 42 is used to intercept and limit the embedded block 513, thereby completing the assembly and fixation between the connecting post 41 and the cylinder 42.

[0041] Example 3: First, manually move the connecting post 41. When the connecting post 41 moves to the position inside the cylinder 42, the surface of the connecting post 41 is pressed against the sloped side of the elastic sheet 522, causing the elastic sheet 522 to deform under the pressure of the connecting post 41. When the connecting post 41 moves to the position where it is fully inserted into the cylinder 42, the positioning groove 521 moves to the position corresponding to the elastic sheet 522, releasing the pressure on the elastic sheet 522. After the elastic sheet 522 loses the pressure, it resets, and after resetting, it is inserted into the positioning groove 521 to fix the position of the connecting post 41, thereby completing the assembly and fixation between the connecting post 41 and the cylinder 42.
