Description

Technical Field

[0001] The present invention relates to the technical field of intelligent vehicle auxiliary equipment, and in particular to an automatic charging seat for an intelligent vehicle. Background Art

[0002] Automatic recharging technology has been widely used in various intelligent electrical appliances, especially in intelligent vehicles used for loading and unloading goods in industry. Existing intelligent vehicles can travel along the specified guide path. They have safety protection and various transfer functions. They belong to the category of wheeled mobile robots. In industrial applications, the transport vehicle does not require a driver. It uses a rechargeable battery as its power source. Generally, its route and behavior can be controlled by a computer, or its route can be set up using an electromagnetic track. The electromagnetic track is attached to the floor, and the unmanned transport vehicle moves and moves according to the information brought by the electromagnetic track, which greatly improves the automation of loading and unloading. In the prior art, when the battery power of the intelligent vehicle is low, there are two main existing replenishment methods, one is to replace the storage battery, and the other is to charge the storage battery. Charging can be done by removing the storage battery or pulling a temporary power line. No matter which method is used, it requires labor and is inconvenient to use if it is operated manually. The method of replacing the storage battery or removing the storage battery for charging will also cause the power supply of the equipment to be interrupted and forced to suspend use. Therefore, it is also necessary to find a new power supply solution that can solve these problems, does not consume manpower, can automatically replenish electricity, and will not shut down due to power interruption and power replenishment, affecting use. In the prior art, the smart car chooses the second charging method, that is, charging the storage battery, and using infrared signals to guide the smart car to automatically return to the charging base for charging. However, sometimes when the smart car is not completely vertically in the charging position, charging cannot be carried out normally, or manual intervention is required for the smart car to charge normally, resulting in low charging efficiency, which needs to be improved. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses an automatic charging seat for a smart car, which is designed with a retractable arc-shaped copper tongue to ensure that the smart car or robot can be charged even if it fails to enter the charging position vertically, thereby improving the charging reliability. When not charging, the charging circuit is physically disconnected, which is safe and reliable. The charging contact end (4) and the receiving end (17) are both installed with infrared ranging devices, which are used to judge the distance between the two to avoid the situation where the charging contact end (4) is accidentally squeezed to cause the circuit to be turned on, thereby preventing electric shock, having double safety protection and strong practicality.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] An intelligent car automatic charging stand, which has a left-right symmetric structure. The charging stand includes a fixed installation part, a power supply part, and a receiving end installed on the intelligent car. The fixed installation part includes a housing, a cover plate, a fixed seat, and an installation base. The power supply part includes a charging contact end, a conductor, an elastic body, a circuit board, a copper sheet, a circular terminal, and a wire. Both the front and rear ends of the housing are provided with openings. The fixed seat is designed with an inner groove and is detachably installed at the front opening of the housing and placed inside the housing. The installation base is placed between the fixed seat and the charging contact end. One end of the conductor is connected to the charging contact end, and the other end passes through the through hole on the installation base and the through hole on the fixed seat in sequence and then corresponds to the copper sheet. The circular terminal is detachably installed on the fixed seat, one end is connected to the copper sheet, and the other end is connected to the circuit board through a wire. After the circuit board is installed in the housing, the rear opening of the housing is closed with the cover plate. The elastic body is located between the fixed seat and the installation base and is sleeved on the outer periphery of the conductor. During charging, when the charging contact end is squeezed by the receiving end, the installation base can move backward in the groove inside the fixed seat, thereby pushing the conductor to move backward in the through hole of the fixed seat, and then connecting with the copper sheet to be energized. Infrared ranging devices are installed on both the charging contact end and the receiving end.

[0006] As a further improvement of the present invention, at least one pair of the power supply parts are symmetrically distributed on the left and right of the fixed seat. The charging range is not restricted, and power supply can be carried out on both sides.

[0007] As a further improvement of the present invention, the charging stand further includes a first magnetic attraction part and a second magnetic attraction part which are both annular structures and can attract each other. The first magnetic attraction part is installed around the charging contact end, and the second magnetic attraction part is installed around the receiving end. By using the magnetic attraction effect, sufficient contact between the charging contact end and the receiving end is ensured, and the charging efficiency is guaranteed.

[0008] As a further improvement of the present invention, a charging contact point is further provided on the charging contact end, and the charging contact point is a retractable arc-shaped copper tongue. The arc design enables a wider contact angle range for the receiving end to contact the charging contact point. Even if the intelligent car equipped with the receiving end fails to enter the charging position vertically, normal charging can still be carried out, improving the charging efficiency.

[0009] As a further improvement of the present invention, both the conductor and the charging contact end are made of copper, the elastic body is a circular spring, and the installation base is a nylon block. Nylon has good flame retardancy and is suitable for being used as the support of electrical connectors.

[0010] As a further improvement of the present invention, a protective cover is installed above the copper sheet and the circular terminal, and the wire passes through the through hole on one side of the protective cover and is connected to the circuit board. The design of the protective cover protects the internal electronic components and extends the service life.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The present application designs a retractable arc-shaped copper tongue, which can ensure that the smart car or robot can charge even if it fails to enter the charging position vertically, improving the charging reliability;

[0013] 2. The present application designs a spring. During charging, the charging contact end is squeezed by the receiving end, causing the mounting base to compress the spring, the conductor to contact the copper sheet, and the circuit to conduct. When not charging or fully charged, the charging contact end and the mounting base return to their original positions, the spring resets, and the charging circuit is physically disconnected, which is safe and reliable;

[0014] 3. Infrared ranging devices are installed on both the charging contact end and the receiving end of the present application. By this, the distance between the two is judged. When the distance is less than a certain value, the circuit can be conducted to avoid the situation where the charging contact end is accidentally squeezed to cause the circuit to conduct, preventing electric shock, having double safety guarantees, and being highly practical.

[0015] In summary, the automatic charging stand for the smart car of the present invention designs a retractable arc-shaped copper tongue, which can ensure that the smart car or robot can charge even if it fails to enter the charging position vertically, improving the charging reliability. When not charging, the charging circuit is physically disconnected, which is safe and reliable. Infrared ranging devices are installed on both the charging contact end and the receiving end. By this, the distance between the two is judged to avoid the situation where the charging contact end is accidentally squeezed to cause the circuit to conduct, preventing electric shock, having double safety guarantees, being highly practical, and having a wide application prospect.

[0021] The following further clarifies the present invention in conjunction with the accompanying drawings and specific implementation modes. It should be understood that the following specific implementation modes are only used to illustrate the present invention and not to limit the scope of the present invention.

[0022] As Figures 1-3 shown, the automatic charging seat of the intelligent vehicle of the present invention has a left-right symmetrical structure. The charging seat includes a fixed installation part, a power supply part, and a receiver 17 installed on the intelligent vehicle. The fixed installation part includes a housing 1, a cover plate 2, a fixed seat 3, and an installation base 5. The power supply part includes a charging contact end 4, a conductor 9, an elastomer 10, a circuit board 14, a copper sheet 15, a round terminal 16, and a wire 14-1. Openings are provided at both the front and rear ends of the housing 1. The fixed seat 3 is designed with an inner groove and is detachably installed at the front opening of the housing 1 and placed inside the housing 1. The installation base 5 is placed between the fixed seat 3 and the charging contact end 4. One end of the conductor 9 is connected to the charging contact end 4, and the other end passes through the through hole on the installation base 5 and the through hole on the fixed seat 3 in sequence and then corresponds to the copper sheet 15. The round terminal 16 is detachably installed on the fixed seat 3, one end is connected to the copper sheet 15, and the other end is connected to the circuit board 14 through the wire 14-1. After the circuit board 14 is installed in the housing 1, the rear opening of the housing 1 is closed with the cover plate 2. The elastomer 10 is located between the fixed seat 3 and the installation base 5 and is sleeved on the outer periphery of the conductor 9. During charging, after the charging contact end 4 is squeezed by the receiver 17, the installation base 5 can move backward in the groove inside the fixed seat 3, thereby pushing the conductor 9 to move backward in the through hole of the fixed seat 3, and then being connected to the copper sheet 15 to be powered on. Infrared ranging devices are installed on both the charging contact end 4 and the receiver 17.

[0023] The power supply part is at least one pair and is symmetrically distributed on the left and right of the fixed seat 3. The charging range is not restricted, and power supply can be carried out on both sides.

[0024] The charging stand further includes a first magnetic attraction part 18 and a second magnetic attraction part 19 which are both annular structures and can attract each other. The first magnetic attraction part 18 is installed around the charging contact end 4, and the second magnetic attraction part 19 is installed around the receiving end 17. By using the magnetic attraction effect, sufficient contact between the charging contact end 4 and the receiving end 17 is ensured, and the charging efficiency is guaranteed.

[0025] The charging contact end 4 is further provided with a charging contact point 4-1, and the charging contact point 4-1 is a retractable arc-shaped copper tongue. The arc design enables a wider contact angle range for the receiving end 17 to contact the charging contact point 4-1. Even if the intelligent vehicle installed with the receiving end 17 fails to enter the charging position vertically, normal charging can still be achieved, improving the charging efficiency.

[0026] Both the conductor 9 and the charging contact end 4 are made of copper, the elastic body 10 is a circular spring, and the mounting base 5 is a nylon block. Nylon has good flame retardancy, a high melting point, and a heat distortion temperature that can reach up to 250°C, making it suitable for use as the support of electrical connectors.

[0027] A protective cover 11 is installed above the copper sheet 15 and the circular terminal 16. The wire 14-1 passes through a through hole on one side of the protective cover 11 and is connected to the circuit board 14. The design of the protective cover 11 protects the internal electronic components and extends the service life.

[0028] As Figure 2 shown, the charging contact end 4 and the fixed seat 3 are fixedly connected by an internal hexagonal screw 6, and a flat gasket 7 and a washer 8 are sequentially installed in the middle. The protective cover 11 is fixedly connected to the fixed seat 3 by a cross-recessed pan head screw 12, and the Suhu housing 1 and the fixed seat 3 are fixedly connected by an internal hexagonal screw 13. All the screws are standard parts in the prior art.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The present application designs a retractable arc-shaped copper tongue, which can ensure that the intelligent vehicle or robot can still charge even if it fails to enter the charging position vertically, improving the charging reliability;

[0031] 2. The present application designs a spring. During charging, the charging contact end 4 is squeezed by the receiving end 17, causing the mounting base 5 to compress the spring, the conductor 9 to contact the copper sheet 15, and the circuit to conduct. When not charging or fully charged, the charging contact end 4 and the mounting base 5 return to their original positions, the spring resets, and the charging circuit is physically disconnected, which is safe and reliable;

[0032] 3. Infrared ranging devices are installed on both the charging contact end 4 and the receiving end 17 of this application. By this, the distance between the two is judged. Only when the distance is less than a certain value can the circuit be conducted, so as to avoid the situation that the charging contact end 4 is accidentally squeezed to cause the loop to conduct, prevent electric shock, have double safety guarantees, and have strong practicability.

[0033] In summary, for the intelligent vehicle automatic charging base of the present invention, a retractable arc-shaped copper tongue is designed, which can ensure that the intelligent vehicle or robot can be charged even if it fails to enter the charging position vertically, improving the charging reliability. When not charging, the charging circuit is physically disconnected, safe and reliable. Infrared ranging devices are installed on both the charging contact end 4 and the receiving end 17. By this, the distance between the two is judged to avoid the situation that the charging contact end 4 is accidentally squeezed to cause the loop to conduct, prevent electric shock, have double safety guarantees, have strong practicability, and have a wide application prospect.

[0034] It should be noted that the above content only illustrates the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. For those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches all fall within the protection scope of the claims of the present invention.
