Description

Technical Field

[0001] The present invention belongs to the technical field of anti-stuck charging in automobile battery swap stations, and in particular, relates to an anti-stuck charging mechanism in automobile battery swap stations and a use method thereof. Background Art

[0002] In the field of electric vehicle battery swap station technology, the performance and reliability of the charging mechanism play a key role in the efficient and safe operation of the entire battery swap process. With the popularization of electric vehicles and the gradual promotion of battery swap models, higher requirements are placed on the charging mechanism.

[0003] Traditional charging mechanisms in car swap stations often lack sufficient versatility and adaptability in design. Since electric vehicles produced by different automobile manufacturers have significant differences in the specifications, location and body structure layout of the charging interfaces, existing charging mechanisms are difficult to accurately dock with the charging interfaces of various models. This inaccurate docking can easily cause mechanical interference, causing the charging mechanism to bear uneven stress during the connection process, which in turn leads to frequent jamming. For example, when the angle of the charging plug and the vehicle charging interface deviates slightly, forced insertion may cause the mechanical structure of the plug to deform or get stuck, not only preventing normal charging, but also damaging the charging equipment and vehicle interface, increasing maintenance costs and operational risks.

[0004] Furthermore, existing charging mechanisms are insufficient in coping with complex usage environments. Battery swap stations are usually in an open environment, and dust, mud, moisture and other impurities can easily enter the interior of the charging mechanism. Long-term accumulation will pollute and corrode the mechanical transmission components and electrical connection parts, aggravate the friction between the components, and thus increase the possibility of jamming. At the same time, the lack of an effective maintenance mechanism and the inability to lubricate or adjust the components in time after they are worn further aggravate the jamming problem. In view of this, the present invention is specially proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an anti-stuck charging mechanism and a method of use for a car battery swap station that can overcome the above problems or at least partially solve the above problems.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a charging mechanism for preventing jamming in a car battery swap station and a method of use, including a charging pile, and also including a visual sensor fixedly connected to the charging pile, the charging pile is symmetrically provided with connecting grooves, and a connecting arm is rotatably connected to the connecting groove; a charging connector is arranged on the connecting arm, a plug board is fixedly connected to the charging connector, a plug slot is provided on the plug board, a connecting block is fixedly connected to the plug slot, an air slot is provided on the charging connector, and a blowing slot is penetrated through the plug board, and the air slot corresponds to the blowing slot; a contact and an extrusion rod are slidably connected to the connecting block; two flexible plates are fixedly connected to the charging connector, a pry bar is rotatably connected to the flexible plate, and a fixed plate is fixedly connected to the flexible plate.

[0007] Furthermore, the connecting arm is rotatably connected to the first telescopic arm, the first telescopic arm is fixedly connected to the first movable axis, the second telescopic arm is rotatably connected to the first movable axis, the second telescopic arm is fixedly connected to the second movable axis, the second movable axis is rotatably connected to the third telescopic arm, the third telescopic arm is fixedly connected to the third movable axis, the first movable axis is rotatably connected to the end arm, and the first movable axis, the second movable axis and the end arm are all fixedly connected with laser ranging sensors.

[0008] Furthermore, a charging connector is fixedly connected to the end arm, a shell is fixedly connected to the charging connector, a built-in partition is fixedly connected to the shell, an air groove is provided on the built-in partition, and a plug board is fixedly connected to the charging connector.

[0009] Furthermore, a push rod is slidably connected to the connection block, and a contact is fixedly connected to the push rod.

[0010] Furthermore, a pressing spring is fixedly connected to the pressing rod, and the pressing spring is slidably connected to the inner wall of the connecting block.

[0011] Furthermore, a flexible board is fixedly connected to the built-in spacer board, a slot is provided on the flexible board, the slots on the two flexible boards are opposite to each other, a fixed board is fixedly connected to the flexible board, and the fixed board is semicircular.

[0012] Furthermore, a pry bar is slidably connected to the fixed plate, a connecting spring is fixedly connected to the pry bar, and a flexible plate is fixedly connected to the connecting spring.

[0013] Furthermore, one end of the pry bar away from the fixing plate passes through the slot.

[0014] Furthermore, the method for using the anti-stuck charging method of the automobile swap station includes the following steps:

[0015] Step 1: Multi-DOF adaptive docking:

[0016] The connecting arm on the charging pile can be rotated on the charging pile, driving the first telescopic arm to rotate, the first movable axis on the first telescopic arm drives the second telescopic arm to rotate, the second movable axis on the second telescopic arm drives the third telescopic arm to rotate, the third movable axis on the third telescopic arm drives the terminal arm to rotate, and the terminal arm drives the charging connector to rotate. By installing multiple laser ranging sensors on the charging pile, the laser ranging sensor works based on the laser time of flight TOF or phase difference measurement principle. It emits laser pulses to the target charging interface or its surrounding area, and then receives the reflected light. According to the laser propagation speed in the air being approximately constant and the time interval between emission and reception, the distance from the sensor to the target can be calculated. For example, if the laser pulse returns after a time t after emission, the distance d=c*t / 2, where c is the speed of light. In the charging docking system, multiple laser ranging sensors are distributed around the charging mechanism to measure the distance to the charging interface from different directions, thereby obtaining the position information of the charging interface in three-dimensional space, further supplementing and refining the visual sensor. Sensor data and visual sensors High-precision visual sensors such as CCD or CMOS cameras are installed at specific locations of the charging mechanism to capture images of the charging interface of the electric vehicle. The visual sensor focuses light onto the image sensor through a lens, converts the optical signal into an electrical signal, and then generates a digital image. For example, when the vehicle is close to the charging device, the visual sensor will continue to capture the area around the charging interface. These images contain information such as the appearance shape, color marking, and angle relative to the sensor of the charging interface. By analyzing these images, the approximate position and posture of the charging interface can be preliminarily determined. The three-dimensional spatial position information of the vehicle charging interface and the posture information of the vehicle can be fully sensed. Using these data, the built-in intelligent control algorithm can accurately calculate the adjustment path and angle required by the charging mechanism, and realize the adaptive adjustment of the charging plug in multiple degrees of freedom such as translation, rotation, and tilt, ensuring accurate docking with the charging interfaces of different models, effectively avoiding the jamming phenomenon caused by docking deviation, and greatly improving the versatility and compatibility of the charging mechanism.

[0017] Furthermore, the method for using the anti-stuck charging method of the automobile battery swap station also includes the following steps:

[0018] Step 2: Automatic cleaning:

[0019] After the car connector corresponds to the plug slot, the car plug will squeeze the contact on the connection block, the contact pushes the push rod, the push rod pushes the squeezing spring, the squeezing spring pushes the squeezing rod, the squeezing rod squeezes the air inside the air slot, and pushes the air inside the air slot to be blown out from the blowing slot, cleaning the surface dust of the plug board and reducing the risk of jamming;

[0020] Step 3: Flexible buffer mechanism:

[0021] When an unexpected impact force occurs during the charging process, such as a sudden shaking of the vehicle or a collision during docking, the two sets of flexible plates will first approach each other, and the fixed plate on the flexible plate will push one end of the pry bar on the other set. Under the action of the connecting spring, the ends of the two sets of pry bars close to the fixed plate will move to a horizontal position relative to each other, and the position of the pry bar close to the slot will move to the other end of the slot, dissipating the remaining energy smoothly, avoiding damage to the mechanical structure of the charging mechanism caused by rigid impact and the resulting jamming.

[0022] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: the connecting arm on the charging pile of the present invention can be rotated on the charging pile, driving the first telescopic arm to rotate, the first movable axis on the first telescopic arm drives the second telescopic arm to rotate, the second movable axis on the second telescopic arm drives the third telescopic arm to rotate, the third movable axis on the third telescopic arm drives the terminal arm to rotate, and the terminal arm drives the charging connector to rotate. By installing multiple laser ranging sensors and visual sensors on the charging pile, the three-dimensional spatial position information of the car charging interface and the posture information of the vehicle can be fully sensed. Using these data, the built-in intelligent control algorithm can accurately calculate the adjustment path and angle required for the charging mechanism, realize adaptive adjustment of the charging plug in multiple degrees of freedom, ensure accurate docking with charging interfaces of different models, effectively avoid jamming due to docking deviation, and greatly improve the versatility and compatibility of the charging mechanism.

[0023] After the car connector corresponds to the plug slot, the car plug will squeeze the contacts on the connecting block, the contacts push the push rod, the push rod pushes the extrusion spring, the extrusion spring pushes the extrusion rod, the extrusion rod squeezes the air inside the air slot, and pushes the air inside the air slot out from the blowing slot, cleaning the dust on the surface of the plug board and reducing the risk of jamming.

[0024] When an unexpected impact force occurs during the charging process, the two sets of flexible plates will first approach each other, and the fixed plate on the flexible plate will push one end of the pry bar on the other set. Under the action of the connecting spring, the ends of the two sets of pry bars close to the fixed plate will move to a horizontal position relative to each other, and the position of the pry bars close to the slot will move to the other end of the slot, dissipating the remaining energy smoothly, avoiding damage to the mechanical structure of the charging mechanism caused by rigid impact and the resulting jamming.

9. A method for using an anti-stuck charging device at a car swap station, applied to an anti-stuck charging device at a car swap station as claimed in any one of claims 1 to 8, characterized in that: The method for using the anti-stuck charging method of the automobile swap station comprises the following steps: Step 1: Multi-DOF adaptive docking: The connecting arm (4) on the charging pile (1) can be rotated on the charging pile (1), driving the first telescopic arm (41) to rotate; the first movable shaft (411) on the first telescopic arm (41) drives the second telescopic arm (42) to rotate; the second movable shaft (422) on the second telescopic arm (42) drives the third telescopic arm (43) to rotate; the third movable shaft (433) on the third telescopic arm (43) drives the end arm (44) to rotate; the end arm (44) drives the charging connector (5) to rotate; and multiple laser distance measuring sensors (45) are installed on the charging pile (1). The laser distance sensor (45) works based on the principle of laser time of flight (TOF) or phase difference measurement. It emits laser pulses to the target (charging interface or its surrounding area) and then receives the reflected light. According to the propagation speed of the laser (approximately constant in air) and the time interval between emission and reception, the distance from the sensor to the target can be calculated. For example, if the laser pulse returns after a time t after emission, the distance d = c*t / 2 (where c is the speed of light). In the charging docking system, multiple laser distance sensors (45) are distributed around the charging mechanism to measure the distance to the charging interface from different directions. The position information of the charging interface in three-dimensional space is obtained to further supplement and refine the data of the visual sensor (2)) and the visual sensor 2) (a high-precision visual sensor (2) (such as a CCD or CMOS camera) is installed at a specific position of the charging mechanism to capture the image of the charging interface of the electric vehicle. The visual sensor (2) focuses light onto the image sensor through a lens, converts the optical signal into an electrical signal, and then generates a digital image. For example, when the vehicle is close to the charging device, the visual sensor (2) will continue to capture the area around the charging interface. These images contain information such as the appearance shape, color marking, and angle relative to the sensor of the charging interface. By analyzing these images, the approximate position and posture of the charging interface can be preliminarily determined) can fully perceive the three-dimensional spatial position information of the vehicle charging interface and the posture information of the vehicle. Using these data, the built-in intelligent control algorithm can accurately calculate the adjustment path and angle required by the charging mechanism, realize the adaptive adjustment of the charging plug in multiple degrees of freedom (such as translation, rotation, tilt, etc.), ensure accurate docking with the charging interfaces of different models, effectively avoid the jamming phenomenon caused by docking deviation, and greatly improve the versatility and compatibility of the charging mechanism.

10. A method for charging in an automobile battery swap station to prevent jamming according to claim 9, characterized in that: The method for using the anti-stuck charging method at the automobile swap station also includes the following steps: Step 2: Automatic cleaning: After the automobile connector corresponds to the plug slot (54), the automobile plug will squeeze the contact (543) on the connection block (541), the contact (543) pushes the push rod (542), the push rod (542) pushes the squeezing spring (544), the squeezing spring (544) pushes the squeezing rod (545), the squeezing rod (545) squeezes the air inside the air slot (522), and pushes the air inside the air slot (522) to be blown out from the blowing slot (523), so as to clean the dust on the surface of the plug plate (53) and reduce the risk of jamming; Step 3: Flexible buffer mechanism: When an unexpected impact force occurs during the charging process (such as a sudden shaking of the vehicle or a collision during docking), the two groups of flexible plates (55) will first approach each other, and the fixed plate (552) on the flexible plate (55) will push one end of the pry bar (553) on the other group. Under the action of the connecting spring (554), the ends of the two groups of pry bars (553) close to the fixed plate (552) will move to a horizontal position relative to each other, and the position of the pry bar (553) close to the slot (551) will move to the other end of the slot (551), so that the remaining energy is smoothly dissipated, thereby avoiding damage to the mechanical structure of the charging mechanism caused by rigid impact and the resulting jamming phenomenon.
