Description

Technical Field

[0001] The present invention relates to the technical field of electronic power, and in particular to a charging pile for charging new energy vehicles and a method of using the same. Background Art

[0002] In recent years, charging piles for new energy vehicles have become an important infrastructure in the new energy vehicle industry chain. They can accurately control the charging current and voltage according to the status and characteristics of the battery, realize an efficient and safe charging process, help extend the battery life, maintain stable battery performance, and reduce dependence on traditional petroleum energy, promote the optimization and adjustment of the energy structure, and improve energy utilization efficiency.

[0003] When not in use, the charging guns of some charging piles for charging new energy vehicles in the prior art are usually fixed to the outside of the power box with some traditional spring clamping structures. The traditional spring clamping structure usually lacks a stable fixing effect. When pedestrians pass by, accidental collisions or scratches on clothes may exert external force on the spring clamping structure, causing the charging gun to fall off. The falling charging gun will cause it to collide with the ground or other objects, which may cause damage to the charging gun casing, internal circuit short circuit or poor contact, and the gun wire may also fall off, and be crushed by passing vehicles, resulting in internal cable breakage and outer skin damage, which in turn affects the normal use of the charging gun and increases the equipment maintenance cost and replacement frequency.

[0021] The present invention provides the following technical solution: a method of use, comprising the charging pile for charging new energy vehicles, the method comprising the following steps:

[0022] S1: Move the movable sleeve so that the movable sleeve drives the inclined groove to move to a position that coincides with the limiting groove, release the radial limiting of the ball, and insert the charging gun into the fixed sleeve. When the charging gun is inserted, the ball is squeezed by the fixed column and moves radially in the limiting groove. When the ball is embedded in the trapezoidal groove on the surface of the fixed column, release the movable sleeve, and the reaction force of the spring resets the movable sleeve and the pressure block. The pressure block limits the ball and completes the fixing of the charging gun.

[0023] S2: Place the gun line inside the support frame, manually rotate the ratchet to form a ring with the support frame to hold the gun line tightly, the rotating column rotates to squeeze the first torsion spring to store elastic potential energy, the ratchet rotates to squeeze the ratchet block, driving the transmission column to rotate and compress the second torsion spring.

[0024] S3: Manually push the ratchet bar upward to slide in the guide rail, squeeze the pawl and drive the support shaft to rotate, apply pressure to the third torsion spring, and the ratchet bar drives the clamp assembly to rise synchronously through the connecting plate to adjust the tension. Stop pushing after reaching the appropriate tension. If the ratchet bar slides in the opposite direction, the pawl engages with the teeth of the ratchet bar under the reaction force of the third torsion spring to prevent it from sliding, and maintain the adjusted tension. If the initial tension needs to be restored, rotate the support shaft to drive the pawl to disengage from the ratchet bar, and the gun line falls to the initial position due to gravity;

[0025] S4: Charging is finished, and the movable sleeve is moved again, so that the movable sleeve drives the inclined groove to move to a position overlapping with the limit groove, the radial limit of the ball is released, and the charging gun is directly pulled out. The charging gun drives the fixed column and the trapezoidal groove to move synchronously, and the trapezoidal groove squeezes the ball to make it withdraw from the trapezoidal groove, and the charging gun is taken out; when the gun line needs to be taken out, the transmission column is manually rotated to drive the ratchet to rotate until it disengages from the ratchet block, and the ratchet is reset with the help of the reaction force of the first torsion spring to release the limit on the gun line.

[0026] The beneficial effects of the present invention are as follows: through the fixing assembly, the charging gun can maintain a stable connection with the power box regardless of whether it is in a relatively static state or under slight external vibrations, and at the same time, the charging gun can be quickly and easily removed when charging is needed, so as to avoid safety hazards caused by the charging gun falling off; through the cooperation of the clamp assembly and the tensioning assembly, not only can the gun line be prevented from falling to the ground due to accidental contact with external force, but the tension of the gun line can also be flexibly adjusted according to the position of the charging port of different models, so as to avoid the gun line being dragged on the ground and being crushed by the vehicle to cause damage to the outer skin, while flexibly adapting to the charging ports and parking positions of different models.

[0043] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0044] Example 1

[0045] Reference Figure 1 , Figure 2 , Figures 4 to 7 , which is the first embodiment of the present invention, provides a charging pile for charging new energy vehicles, the device comprising:

[0046] The charging pile body 100 includes an electric box 101, a gun line 102 fixedly connected to the outer surface of the electric box 101, and a charging gun 103 fixedly installed at the other end of the gun line 102;

[0047] It should be noted that the power box 101 is the core component of the charging pile, which integrates many key electrical equipment, such as charging control module, billing module, communication module, etc. The charging control module is responsible for the precise management and regulation of the entire charging process, including communicating with the battery management system of the new energy vehicle to determine the appropriate charging voltage, current, charging time and other parameters; the billing module is used to record and calculate the charging amount and the corresponding fees; the communication module realizes the connection between the charging pile and the external network such as the operation management platform, the owner's mobile phone APP, etc., so as to transmit the charging status, fault information and other data in real time. In addition, the power box 101 also provides a connection interface with the external power grid to realize the input and reasonable distribution of electric energy, and can also provide an installation basis for the protective mechanism 200, etc. The gun line 102 is an important carrier connecting the power box 101 and the charging gun 103. The charging gun 103 includes multiple wires, which have the dual tasks of transmitting the electric energy required for charging and the charging control signal. The gun line 102 can be flexibly bent within a certain range to ensure that the charging gun 103 can be easily connected to the charging interface of the new energy vehicle. The charging gun 103 is used to directly connect to the charging interface of the new energy vehicle. It has a standard plug structure and precise electrical connection points, and can safely and reliably transmit the electric energy output by the power box 101 to the car battery. At the same time, the charging gun 103 has a series of built-in electrical safety protection devices, such as over-current protection, over-voltage protection, leakage protection, etc., to effectively prevent electrical faults during the charging process and ensure the safety and stability of the charging process.

[0048] The protection mechanism 200 includes a fixing assembly 201 for fixing the charging gun 103 to the outside of the electric box 101, a clamp assembly 202 for preventing the gun line 102 from falling to the ground due to accidental contact with external force, and a tensioning assembly 203 for quickly adjusting the tension of the gun line 102 in cooperation with the clamp assembly 202;

[0049] The fixing assembly 201 includes a fixing sleeve 201a fixedly connected to the outer surface of the electrical box 101, limiting grooves 201b distributed in a circular array on the surface of the fixing sleeve 201a, and a ball 201c movably connected to the inner wall of the limiting groove 201b;

[0050] It should be noted that the internal shape of the fixed sleeve 201a is precisely matched to the outer shape of the charging gun 103, ensuring that the charging gun 103 can maintain good stability after insertion without shaking or shifting, thereby providing a stable fixing foundation for the charging gun 103. The limiting groove 201b is used to radially limit the ball 201c, so that the ball 201c can only move within the limited range of the limiting groove 201b, thereby providing the necessary structural foundation for achieving reliable fixation and convenient unlocking of the charging gun 103.

[0051] The clamp assembly 202 includes a fixing seat 202a disposed outside the electrical box 101, a support frame 202b fixedly connected to the inner surface of the fixing seat 202a, a rotating column 202c fixedly mounted on the inner wall of the supporting frame 202b through a bearing, and a ratchet 202d fixedly sleeved on the outer surface of the rotating column 202c;

[0052] It should be further explained that the fixing seat 202a is used to install the support frame 202b, thereby providing a stable installation foundation for the entire clamp assembly 202, and the support frame 202b is used to provide an installation position for the swivel column 202c and the ratchet 202d. The swivel column 202c can flexibly rotate around its own axis. When the swivel column 202c rotates, it can drive the ratchet 202d to rotate synchronously.

[0053] The tensioning assembly 203 includes a guide rail 203a fixedly connected to the outer surface of the electrical box 101, a ratchet bar 203b in sliding contact with the inner wall of the guide rail 203a, and a connecting plate 203c fixedly installed on the outer surface of the ratchet bar 203b and used in conjunction with the fixing seat 202a.

[0054] Among them, the guide rail 203a is used to provide a stable sliding track for the ratchet bar 203b, ensuring that the ratchet bar 203b slides stably along the vertical straight direction, and the connecting plate 203c is used to accurately transmit the linear motion of the ratchet bar 203b to the clamp assembly 202, control the lifting and lowering of the clamp assembly 202, and further flexibly adjust the tension of the gun line 102.

[0055] Specifically, the fixing assembly 201 also includes a movable sleeve 201d slidably mounted on the outer surface of the ball 201c, a spring 201e mounted on the outer surface of the fixed sleeve 201a, a pressure block 201f fixedly connected to the inner wall of the movable sleeve 201d and used in conjunction with the ball 201c and the spring 201e, and an inclined groove 201g opened on the outer surface of the pressure block 201f and used in conjunction with the ball 201c.

[0056] Among them, the movable sleeve 201d can control the radial movement of the ball 201c by driving the pressure block 201f to move axially, thereby realizing the fixing or unlocking operation of the ball 201c on the charging gun 103. During the movement of the movable sleeve 201d, the spring 201e will be compressed or stretched, thereby storing or releasing elastic potential energy, providing a reset elastic force for the movable sleeve 201d, ensuring that the pressure block 201f always maintains a position overlapping with the limit groove 201b in the absence of external force. When the movable sleeve 201d drives the pressure block 201f and the inclined groove 201g to move to a position overlapping with the ball 201c, the radial force applied to the ball 201c can be released, thereby releasing the limit on the ball 201c and releasing the charging gun 103.

[0057] Furthermore, the fixing assembly 201 further includes a fixing column 201h fixedly mounted on the outer surface of the charging gun 103, and a trapezoidal groove 201i opened on the outer surface of the fixing column 201h and used in conjunction with the ball 201c.

[0058] It should be explained that the fixing column 201h and the charging gun 103 form an integral structure, and the shape and size of the trapezoidal groove 201i are precisely matched with the ball 201c. When the ball 201c is embedded in the trapezoidal groove 201i, it can effectively prevent the charging gun 103 from axial movement, thereby ensuring the reliability and stability of the fixing of the charging gun 103.

[0059] The outer end surface of the spring 201e is fixedly connected to the outer surface of the fixed sleeve 201a, and the outer surface of the pressure block 201f is in sliding contact with the outer surface of the fixed sleeve 201a;

[0060] When the inclined groove 201g moves to a position overlapping with the limiting groove 201b, the limiting of the ball 201c can be released, and when the ball 201c is located in the trapezoidal groove 201i, the fixing column 201h can be fixed.

[0061] When in use, the movable sleeve 201d is moved so that the movable sleeve 201d drives the inclined groove 201g to move to the position where the limiting groove 201b overlaps, so as to release the radial limitation of the ball 201c, and then the charging gun 103 is inserted into the fixed sleeve 201a. When the charging gun 103 is inserted into the fixed sleeve 201a, the ball 201c moves radially in the limiting groove 201b by the squeezing of the fixed column 201h. When the ball 201c is embedded in the trapezoidal groove 201i on the surface of the fixed column 201h, the movable sleeve 201d is released, and the movable sleeve 201d and the pressure block 201f are reset by the reaction force of the spring 201e, so that the pressure block 201f limits the ball 201c, thereby fixing the fixed column 201h and the charging gun 103 through the cooperation of the ball 201c and the trapezoidal groove 201i;

[0062] When the charging gun 103 needs to be unlocked: move the movable sleeve 201d again, so that the movable sleeve 201d drives the inclined groove 201g to move to the position where the limiting groove 201b overlaps to release the radial limitation of the ball 201c. At this time, directly pull out the charging gun 103, and drive the trapezoidal groove 201i on the surface of the fixed column 201h to move synchronously through the charging gun 103, and then squeeze the ball 201c through the inclined surface of the trapezoidal groove 201i, so that the ball 201c withdraws from the trapezoidal groove 201i, so as to achieve the effect of quickly and firmly fixing or removing the charging gun 103.

[0063] In summary, by fixing the component 201, the charging gun 103 can maintain a stable connection with the power box 101 regardless of whether it is in a relatively static state or subjected to slight external vibrations. At the same time, when charging is needed, the charging gun 103 can be quickly and easily removed to avoid safety hazards caused by the charging gun 103 falling off.

[0064] Example 2

[0065] Reference Figure 3 , Figure 8 to Figure 11 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: this embodiment provides a clamp assembly 202 for preventing the gun line 102 from falling to the ground due to accidental contact with external force, and a tensioning assembly 203 for quickly adjusting the tension of the gun line 102 in cooperation with the clamp assembly 202.

[0066] Preferably, the clamp assembly 202 also includes a first torsion spring 202e sleeved on the outer surface of the rotary column 202c, a transmission column 202f fixedly installed on the inner wall of the support frame 202b away from the rotary column 202c through a bearing, a ratchet block 202g fixedly sleeved on the outer surface of the transmission column 202f and used in conjunction with the ratchet 202d, and a second torsion spring 202h sleeved on the outer surface of the transmission column 202f.

[0067] It should be explained that when the ratchet 202d rotates to the position of meshing with the ratchet block 202g, it can form a ring with the support frame 202b, thereby preventing the gun line 102 from falling off due to external force, and preventing the gun line 102 from being crushed by passing vehicles due to falling off. The cooperation between the ratchet 202d and the ratchet block 202g can effectively prevent the ring formed by the ratchet 202d and the support frame 202b from loosening by itself, thereby ensuring that the gun line 102 will not accidentally fall off due to external force. When the rotating column 202c rotates, it can squeeze the first torsion spring 202e, so that the first torsion spring 202e stores elastic potential. Yes, after the external force disappears, the first torsion spring 202e can provide the rotating column 202c with the power to reset, so that the ratchet 202d can smoothly return to its initial state, and the transmission column 202f can also rotate around its own axis. When the ratchet 202d squeezes the ratchet block 202g, the ratchet block 202g will drive the transmission column 202f to rotate synchronously and apply a pressure to the second torsion spring 202h. Then, the reaction force of the second torsion spring 202h will quickly reset the transmission column 202f and the ratchet block 202g, ensuring that the ratchet 202d and the ratchet block 202g remain in a meshing state.

[0068] It should be noted that the outer end surface of the first torsion spring 202e is fixedly connected to the outer surface of the rotary column 202c, the outer end surface of the second torsion spring 202h is fixedly connected to the outer surface of the transmission column 202f, the other ends of the first torsion spring 202e and the second torsion spring 202h are fixedly connected to the outer surface of the support frame 202b, and the connection between the rotary column 202c and the transmission column 202f and the support frame 202b is installed with a bearing sleeve for matching rotation.

[0069] Furthermore, the tensioning assembly 203 also includes a support shaft 203d fixedly mounted on the inner surface of the guide rail 203a through a bearing sleeve, and a ratchet pawl 203e fixedly sleeved on the outer end surface of the support shaft 203d and used in conjunction with the ratchet bar 203b.

[0070] Furthermore, the tensioning assembly 203 also includes a third torsion spring 203f sleeved on the outer surface of the support shaft 203d and used in conjunction with the pawl 203e, and a limit block 203g fixedly connected to both ends of the guide rail 203a to prevent the ratchet bar 203b from falling off.

[0071] What should be explained more is that the support shaft 203d is used to provide a rotating support shaft for the pawl 203e, so that the pawl 203e can rotate around the support shaft 203d. When the ratchet bar 203b slides upward, the pawl 203e can squeeze the ratchet bar 203b and slide through smoothly, and at the same time drive the support shaft 203d to rotate through the ratchet bar 203b, and then apply a pressure to the third torsion spring 203f through the support shaft 203d; and when the ratchet bar 203b tries to slide in the opposite direction, the pawl 203e will quickly engage with the teeth through the reaction force of the third torsion spring 203f, thereby preventing the reverse sliding of the ratchet bar 203b and ensuring the stability of the gun line 102 after the tension is adjusted. The limit block 203g is used to prevent the ratchet bar 203b from sliding out from both ends of the guide rail 203a, and limit the sliding range of the ratchet bar 203b in the guide rail 203a, so as to ensure the reliability and stability of the tensioning assembly 203.

[0072] Specifically, the outer end surface of the third torsion spring 203f is fixedly connected to the outer surface of the guide rail 203a, and the other end of the guide rail 203a is fixedly connected to the outer surface of the support shaft 203d.

[0073] When in use, the gun line 102 is placed inside the support frame 202b, and then the ratchet 202d is manually rotated to form a ring with the support frame 202b, thereby holding the gun line 102 tightly and effectively preventing the gun line 102 from falling off due to external force;

[0074] During the rotation of the ratchet 202d: the rotary column 202c rotates accordingly and squeezes the first torsion spring 202e, so that the first torsion spring 202e stores elastic potential energy. When the external force disappears, the first torsion spring 202e releases the elastic potential energy to provide a reset force for the rotary column 202c, so that the ratchet 202d returns to its initial state. At the same time, when the ratchet 202d rotates, it squeezes the ratchet block 202g. The ratchet block 202g drives the transmission column 202f to rotate synchronously and compresses the second torsion spring 202h. Subsequently, the transmission column 202f and the ratchet block 202g are quickly reset by the reaction force of the second torsion spring 202h, ensuring that the ratchet 202d and the ratchet block 202g are continuously in meshing state, maintaining the stability of the gun line 102, and completing the operation of preventing the gun line from falling off;

[0075] When the tension of the gun line 102 needs to be adjusted: manually push the ratchet bar 203b upward to slide in the guide rail 203a, so that the ratchet bar 203b squeezes the pawl 203e and passes smoothly, and at the same time drives the support shaft 203d to rotate through the pawl 203e, thereby applying pressure to the third torsion spring 203f, and the ratchet bar 203b drives the clamp assembly 202 to rise synchronously through the connecting plate 203c, so as to achieve the effect of adjusting the tension of the gun line 102;

[0076] When the gun line 102 reaches a suitable tension, the ratchet bar 203b is stopped from being pushed. When the ratchet bar 203b slides in the reverse direction due to gravity, the ratchet 203e will quickly mesh with the teeth of the ratchet bar 203b under the reaction force of the third torsion spring 203f to prevent it from sliding in the reverse direction, thereby maintaining the adjusted tension of the gun line 102.

[0077] If the gun line 102 needs to be restored to the initial tension, the support shaft 203d is rotated to drive the ratchet 203e to rotate to a position where it is disengaged from the ratchet bar 203b, so that the gun line 102 can fall to the initial position by gravity;

[0078] When the gun line 102 needs to be removed, the transmission column 202f can be manually rotated again to drive the ratchet 202d to rotate to a position where the ratchet 202d is disengaged from the ratchet 202d, and the ratchet 202d is reset to the initial position by the reaction force of the first torsion spring 202e to release the limit on the gun line 102.

[0079] In summary, through the cooperation of the clamp assembly 202 and the tensioning assembly 203, not only can the gun line 102 be prevented from falling to the ground due to accidental contact with external force, but the tension of the gun line 102 can also be flexibly adjusted according to the position of the charging port of different models, so as to avoid the gun line 102 being dragged on the ground and crushed by the vehicle to cause damage to the outer skin, while flexibly adapting to the charging ports and parking positions of different models.

[0080] Example 3

[0081] Reference Figures 1 to 11 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a method of use, including a charging pile for charging new energy vehicles, and the method includes the following steps:

[0082] S1: Move the movable sleeve 201d, so that the movable sleeve 201d drives the inclined groove 201g to move to a position that coincides with the limiting groove 201b, release the radial limit of the ball 201c, and insert the charging gun 103 into the fixed sleeve 201a. When the charging gun 103 is inserted, the ball 201c is squeezed by the fixed column 201h and moves radially in the limiting groove 201b. When the ball 201c is embedded in the trapezoidal groove 201i on the surface of the fixed column 201h, release the movable sleeve 201d, and the reaction force of the spring 201e resets the movable sleeve 201d and the pressure block 201f. The pressure block 201f limits the ball 201c, and the charging gun 103 is fixed;

[0083] S2: Place the gun line 102 inside the support frame 202b, manually rotate the ratchet 202d to form a ring with the support frame 202b to hold the gun line 102 tightly, the rotating column 202c rotates and squeezes the first torsion spring 202e to store elastic potential energy, the ratchet 202d rotates and squeezes the ratchet block 202g, driving the transmission column 202f to rotate and compress the second torsion spring 202h, after the external force disappears, the first torsion spring 202e and the second torsion spring 202h respectively reset the rotating column 202c, the transmission column 202f and the ratchet block 202g to maintain the stability of the gun line 102;

[0084] S3: Manually push the ratchet bar 203b upward to slide in the guide rail 203a, squeeze the pawl 203e and drive the support shaft 203d to rotate, apply pressure to the third torsion spring 203f, and the ratchet bar 203b drives the clamp assembly 202 to rise synchronously through the connecting plate 203c to adjust the tension. After reaching the appropriate tension, stop pushing. If the ratchet bar 203b slides in the opposite direction, the pawl 203e engages with the teeth of the ratchet bar 203b under the reaction force of the third torsion spring 203f to prevent it from sliding, and maintain the adjusted tension. If the initial tension needs to be restored, the support shaft 203d is rotated to drive the pawl 203e to disengage from the ratchet bar 203b, and the gun line 102 falls to the initial position due to gravity;

[0085] S4: Charging is terminated, and the movable sleeve 201d is moved again, so that the movable sleeve 201d drives the inclined groove 201g to move to a position overlapping with the limiting groove 201b, and the radial limiting of the ball 201c is released, and the charging gun 103 is directly pulled out. The charging gun 103 drives the fixed column 201h and the trapezoidal groove 201i to move synchronously, and the trapezoidal groove 201i squeezes the ball 201c to make it withdraw from the trapezoidal groove 201i, and the charging gun 103 is taken out; when the gun line 102 needs to be taken out, the transmission column 202f is manually rotated to drive the ratchet 202d to rotate until it disengages from the ratchet block 202g, and the ratchet 202d is reset with the help of the reaction force of the first torsion spring 202e, and the limiting of the gun line 102 is released.

[0086] In summary, through the fixing component 201, the charging gun 103 can maintain a stable connection with the power box 101 regardless of whether it is in a relatively static state or under slight external vibrations. At the same time, when charging is needed, the charging gun 103 can be quickly and easily removed to avoid safety hazards caused by the charging gun 103 falling off; through the cooperation of the clamp component 202 and the tensioning component 203, not only can the gun line 102 be prevented from falling to the ground due to accidental contact with external force, but the tension of the gun line 102 can also be flexibly adjusted according to the position of the charging port of different models, so as to avoid the gun line 102 being dragged on the ground and crushed by the vehicle to cause damage to the outer skin, while flexibly adapting to the charging port and parking position of different models.
