Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0040] The core of the utility model provides a kind of automatic charging device, and the cost of opening and closing door action is low and high reliability.
[0041] Please combine Figures 1 to 8 The utility model embodiment provides a kind of automatic charging device, including housing 1, charging arm 2, energy storage piece 3 (such as Figure 4 As shown) and flexible traction piece 4, housing 1 is equipped with opening 11, and opening 11 is equipped with movable opening and closing door 12;Charging arm 2 is arranged in housing 1, and charging arm 2 has initial position in housing 1 and charging position outside housing 1, and is configured to reciprocate between initial position and charging position;Energy storage piece 3 is connected between opening and closing door 12 and housing 1, for driving opening and closing door 12 to open or close;Flexible traction piece 4 includes first transmission section 43, second transmission section 44 and traction section connected between first transmission section 43 and second transmission section 44, first transmission section 43 is connected with opening and closing door 12, and first transmission section 43 is arranged at angle with the direction of movement of charging arm 2, second transmission section is configured to be connectable with charging arm 2;When charging arm 2 moves from initial position to charging position, charging arm 2 releases the constraint force on second transmission section 44, so that energy storage piece 3 drives opening and closing door 12 to open;When charging arm 2 moves from 2 charging position to 2 initial position, charging arm 2 applies constraint force to second transmission section 44 to drive first transmission section 43 to close opening and closing door 12 through traction section;Or, when charging arm 2 moves from initial position to charging position, charging arm 2 applies constraint force to second transmission section 44 to drive first transmission section 43 to open opening and closing door 12 through traction section;When charging arm 2 moves from charging position to initial position, charging arm 2 releases the constraint force on second transmission section 44, so that energy storage piece 3 drives opening and closing door 12 to close.
[0042] When the power receiving device needs to be charged, one solution is that the charging arm 2 moves from the initial position to the charging position, at this time, the charging arm 2 releases the constraint force on the second transmission segment 44, so that the second transmission segment 44 is transmitted to the first transmission segment 43 through the traction segment without constraint force, the first transmission segment 43 releases the opening and closing door 12, so that the energy storage member 3 can drive the opening and closing door 12 to open, and the charging arm 2 can extend from the opening 11 to charge the power receiving device; when the charging is completed, the charging arm 2 moves from the charging position to the initial position, at this time, the charging arm 2 applies a constraint force to the second transmission segment 44, so that the second transmission segment 44 applies a constraint force to the first transmission segment 43 through the traction segment, and then the first transmission segment 43 drives the opening and closing door 12 to close, so that the opening and closing door 12 plays a protective role on the opening 11; when the charging arm 2 applies a constraint force to the second transmission segment 44 to drive the opening and closing door 12 to close, the first transmission segment 43 is arranged at an angle with the movement direction of the charging arm 2, which can absorb and disperse the impact force of the movement of the charging arm 2 on the opening and closing door to a certain extent, has a certain buffering effect, is beneficial to guarantee the reliability of the opening and closing door, and enhances the impact resistance of the system.
[0043] Another solution is that the charging arm 2 moves from the initial position to the charging position, at this time, the charging arm 2 applies a constraint force to the second transmission segment 44, so that the second transmission segment 44 applies a constraint force to the first transmission segment 43 through the traction segment, and then the first transmission segment 43 drives the opening and closing door 12 to open, so that the charging arm 2 can extend from the opening 11 to charge the power receiving device; when the charging arm 2 applies a constraint force to the second transmission segment 44 to drive the opening and closing door 12 to open, the first transmission segment 43 is arranged at an angle with the movement direction of the charging arm 2, which can absorb and disperse the impact force of the movement of the charging arm 2 on the opening and closing door to a certain extent, has a certain buffering effect, is beneficial to guarantee the reliability of the opening and closing door, and enhances the impact resistance of the system. When the charging is completed, the charging arm 2 moves from the charging position to the initial position, at this time, the charging arm 2 releases the constraint force on the second transmission segment 44, so that the second transmission segment 44 is transmitted to the first transmission segment 43 through the traction segment without constraint force, the first transmission segment 43 releases the opening and closing door 12, so that the energy storage member 3 can drive the opening and closing door 12 to close, and plays a protective role on the opening 11.
[0044] Therefore, the automatic charging device realizes the opening and closing of the opening and closing door 12 without additional power driving, simplifies the start and stop steps of the opening and closing door 12 action, reduces the cost of the opening and closing door 12 action, and makes the opening and closing door 12 action less susceptible to interference. In addition, it can also avoid human error to make the opening and closing door 12 in an abnormal open state, and has high reliability. In addition, the first transmission section 43 is arranged at an angle with the movement direction of the charging arm 2, which can absorb and disperse the impact force of the charging arm 2 movement on the opening and closing door to a certain extent, has a certain buffering effect, is beneficial to ensure the reliability of the opening and closing door opening or closing, and enhances the anti-impact ability of the system.
[0045] As more preferred, in some embodiments, the energy storage member 3 has potential energy that always opens the opening and closing door 12, the charging arm 2 is provided with a trigger part, when the charging arm 2 moves from the initial position to the direction close to the opening and closing door 12, the trigger part releases the constraint force on the second transmission section 44, and the energy storage member 3 drives the opening and closing door 12 to open; when the charging arm 2 moves from the charging position to the initial position, the trigger part applies a constraint force to the second transmission section 44 to drive the first transmission section 43 to close the opening and closing door 12 through the traction section. That is, the energy storage member 3 is used to open the opening and closing door 12 before the charging arm 2 moves to the opening and closing door 12, which is beneficial to reduce the possibility of collision between the charging arm 2 and the opening and closing door 12 in abnormal conditions, and when the charging arm 2 moves from the initial position to the charging position, the trigger part releases the constraint force on the second transmission section 44, which is equivalent to disconnecting the transmission connection between the charging arm 2 and the second transmission section 44. This is beneficial to reduce the load when the charging arm 2 moves to the charging position, improve the movement stability of the charging arm 2, and improve the reliability of charging. Moreover, when the flexible traction member 4 is abnormal, the trigger part can be manually released from the constraint force on the second transmission section 44 (for example, when the second transmission section 44 is hung with the trigger part, the second transmission section 44 can be removed from the trigger part). In this way, the energy storage member 3 can keep the opening and closing door 12 in an open state, avoiding the influence of abnormal flexible traction member 4 on normal charging.
[0046] Of course, in other embodiments, the skilled in the art can also make the energy storage member 3 have the potential energy to always make the opening and closing door 12 closed based on other considerations, when the charging arm 2 moves from the initial position to the direction close to the opening and closing door 12, the charging arm 2 exerts the constraint force on the second transmission segment 44 to make the first transmission segment 43 drive the opening and closing door 12 to open through the traction segment; when the charging arm 2 moves from the charging position to the initial position, the charging arm 2 releases the constraint force on the second transmission segment 44, so that the energy storage member 3 drives the opening and closing door 12 to close.
[0047] As shown in Figure 3 and Figure 6 , in some embodiments, the second transmission segment 44 is detachably connected with the trigger part, the charging arm 2 has a set position in the housing, the housing 1 is provided with a limiting part 13, the limiting part 13 is arranged in the movement path of the second transmission segment 44, for limiting the position of the second transmission segment 44 when the charging arm 2 moves from the initial position to the set position, so that the second transmission segment 44 is separated from the trigger part, and the opening and closing door remains in the open state; when the charging arm 2 moves from the charging position to the set position, the trigger part is connected with the second transmission segment 44; when the charging arm 2 moves from the set position to the initial position, the trigger part drives the second transmission segment 44 to move, so that the opening and closing door 12 is closed.
[0048] That is, by arranging the limiting part 13 for limiting the second transmission segment 44 on the housing 1, it is beneficial to ensure that the flexible traction member 4 maintains the preset posture, avoids the flexible traction member 4 being disturbed by the charging arm 2 or foreign matters in the case that the opening and closing door 12 is opened, and it is beneficial to ensure that the trigger part drives the second transmission segment 44 to drive the opening and closing door 12 to close only when the charging arm 2 reaches the set position, so as to ensure the reliability of the opening and closing door 12 to close and open, and further reduce the possibility of collision between the charging arm 2 and the opening and closing door 12 in abnormal cases.
[0049] Further, considering the convenience of connecting the flexible traction member 4 with the charging arm 2, please combine Figure 1 , Figure 3 and Figure 6 , in some embodiments, the trigger part includes a hanging body 211, when the charging arm 2 is located between the initial position and the set position, the hanging body 211 is located on the side of the limiting part 13 away from the opening and closing door 12, and the second transmission segment 44 is hung on the hanging body 211; when the charging arm 2 is located between the charging position and the set position, the hanging body 211 is located on the side of the limiting part 13 towards the opening and closing door 12, and the second transmission segment 44 is hung on the limiting part 13.
[0050] That is, the second transmission section 44 is hung on the hanging body 211 to achieve the connection of the second transmission section 44 and the charging arm 2, which is simple and convenient to achieve. It can be understood that when the opening and closing door 12 is closed, the second transmission section 44 is hung on the hanging body 211, and the flexible traction member 4 has a certain tension between the hanging body 211 and the opening and closing door 12, so that the opening and closing door 12 remains closed. With the extension of the charging arm 2, the hanging body 211 moves synchronously with the charging arm 2, so that the second transmission section 44 moves towards the opening and closing door 12. At this time, under the action of the energy storage member 3, the opening and closing door 12 is opened. In the process of opening the opening and closing door 12, the flexible traction member 4 is pulled to move together, that is, the length of the flexible traction member 4 relaxed with the extension of the charging arm 2 is changed into the length of the opening and closing door 12 moving together with the flexible traction member 4. When the opening and closing door 12 is completely opened, the hanging body 211 moves to the limiting member 13, so that the second transmission section 44 is hung on the limiting member 13, so that the second transmission section 44 does not continue to move towards the opening and closing door 12 when the hanging body 211 continues to extend with the charging arm 2. When the charging arm 2 is retracted, the hanging body 211 moves synchronously with the charging arm 2. When the hanging body 211 moves to the position of the limiting member 13, the second transmission section 44 is hung on the hanging body 211, and then moves with the hanging body 211 when the hanging body 211 continues to move with the retraction of the charging arm 2. The hanging body 211 drives the second transmission section 44 away from the limiting member 13, so that the flexible traction member 4 finally drives the opening and closing door 12 to close. It can be seen that the scheme is convenient to realize the free switching of the second transmission section 44 between the hanging body 211 and the limiting member 13 during the movement of the hanging body 211.
[0051] It should be noted that the specific structure of the hanging body is not limited in the embodiment, as long as it can play the role of hanging the second transmission section 44. In some embodiments, the hanging body 211 includes a hanging line column, a hook, a hanging plate, etc.
[0052] In addition, the specific structure, number and distribution of the limiting member 13 are not limited in the embodiment, as long as the limiting member 13 can limit the second transmission section 44 when the opening and closing door 12 is completely opened.
[0053] As shown in Figure 3 and Figure 6 In some embodiments, the limiting member 13 includes a first limiting pulley 131 and a second limiting pulley 132 arranged at intervals along the direction perpendicular to the movement direction of the charging arm 2, and the hanging body 211 is configured to pass between the first limiting pulley 131 and the second limiting pulley 132.
[0054] That is, when the hanging body 211 approaches the opening and closing door 12 with the extension of the charging arm 2, the hanging body 211 moves to the position between the first limiting pulley 131 and the second limiting pulley 132, and the second transmission section 44 changes from the state of being hung with the hanging body 211 to the state of being hung with the first limiting pulley 131 and the second limiting pulley 132, and with the continuous extension of the charging arm 2, the hanging body 211 passes between the first limiting pulley 131 and the second limiting pulley 132, at this time, the hanging body 211 gradually moves away from the second transmission section 44; when the hanging body 211 moves away from the opening and closing door 12 with the retraction of the charging arm 2, the hanging body 211 moves to the position between the first limiting pulley 131 and the second limiting pulley 132, and the second transmission section 44 changes from the state of being hung with the first limiting pulley 131 and the second limiting pulley 132 to the state of being hung with the hanging body 211, and with the continuous retraction of the charging arm 2, the hanging body 211 drives the second transmission section 44 to move away from the opening and closing door 12, and further drives the opening and closing door 12 to close. It can be seen that, in this arrangement, the first limiting pulley 131 and the second limiting pulley 132 facilitate the guidance of the traction section, and the friction between the traction section and the first limiting pulley 131 and the second limiting pulley 132 is small, and the passing of the hanging body 211 between the first limiting pulley 131 and the second limiting pulley 132 is beneficial to the formation of a symmetrical structure, so that the stress is more uniform, and the switching connection of the second transmission section 44 with the hanging body 211 and the limiting piece 13 is facilitated.
[0055] It should be noted that, in the embodiments of the utility model, the extension of the charging arm 2 refers to the process that the charging arm 2 moves from the initial position to the charging position, and the retraction of the charging arm 2 refers to the process that the charging arm moves from the charging position to the initial position. Further, Figure 3 、 Figure 4 、 Figure 6 and Figure 7 It is shown that, in some embodiments, the opening and closing door 12 includes a slidable first door body 121 and a second door body 122, the number of the first transmission sections 43 is two, the two first transmission sections 43 are respectively connected with the first door body 121 and the second door body 122 in correspondence, the traction section includes a first traction section 41 and a second traction section 42 respectively located between the two first transmission sections 43 and the second transmission section 44, the first traction section 41 passes from the outside of the first limiting pulley 131, the second traction section 42 passes from the outside of the second limiting pulley 132, and the second transmission section 44 is located on the side of the first limiting pulley 131 and the second limiting pulley 132 away from the opening and closing door 12.
[0056] That is to say, the opening and closing door 12 in the embodiment is a sliding double door, that is, the first door body 121 and the second door body 122 are opened or closed in a sliding manner, the movement manner is simple, and the space occupied in the direction perpendicular to the opening and closing door 12 is small, which is beneficial to make the structure compact. Of course, in other embodiments, the opening and closing door 12 can also be opened by rotating or by planar movement.
[0057] In addition, it can be understood that in this scheme, the second transmission section 44 is a U-shaped or V-shaped bending part, so that the two ends of the second transmission section 44 are connected with the first traction section 41 and the second traction section 42 respectively, and the bending of the second transmission section 44 reverses the direction, so that the two open ends of the first traction section 41 and the second traction section 42 correspond to the first door body 121 and the second door body 122 respectively, thereby realizing the corresponding connection of the first traction section 41 and the second traction section 42 with the first door body 121 and the second door body 122 respectively, and the second transmission section 44 is the part farthest from the opening and closing door 12 as the closed end of the flexible traction member 4. The second transmission section 44 is located on the side of the limiting member 13 away from the opening and closing door 12, and when the opening and closing door 12 is closed, the second transmission section 44 is hung on the hanging body 211. When the hanging body 211 moves towards the opening and closing door 12, the second bending part 43 moves towards the opening and closing door 12, so that the first traction section 41 and the second traction section 42 release the first door body 121 and the second door body 122 at the same time, so that the first door body 121 and the second door body 122 move away from each other synchronously, realizing the opening of the opening and closing door 12. When the second transmission section 44 moves away from the opening and closing door 12 along with the hanging body 211, the first door body 121 and the second door body 122 can be driven to move towards each other synchronously by the first traction section 41 and the second traction section 42, so that the first door body 121 and the second door body 122 move close to each other to be closed. It can be understood that the first traction section 41 is arranged on the outer side of the first limiting pulley 131, and the second traction section 42 is arranged on the outer side of the second limiting pulley 132, so that the limiting of the first limiting pulley 131 and the second limiting pulley 132 can make the first traction section 41 and the second traction section 42 have a gap, so as to facilitate the passing of the hanging body 211 between the first traction section 41 and the second traction section 42. In this way, it is beneficial to make the second transmission section 44 hung on the first limiting pulley 131 and the second limiting pulley 132 after the hanging body 211 passes through the first limiting pulley 131 and the second limiting pulley 132, and at the same time, it is beneficial to form a symmetrical structure, so that the two ends of the flexible traction member 4 are more uniform in stress, and the path of the flexible traction member 4 is simple. It should be noted that the specific forming manner of the flexible traction member 4 is not limited in the embodiment, that is, the flexible traction member 4 can be an integrally formed structure, or can be connected by multiple sections.
[0058] It should be noted that the above embodiments do not specifically limit the sliding direction of the opening and closing door 12, as long as the opening and closing door 12 can be opened or closed by sliding.
[0059] like Figure 4 and Figure 7 As shown, in some embodiments, the opening and closing door 12 is configured to slide along a direction perpendicular to the movement of the charging arm 2, and the housing 1 is also provided with a guide pulley 14 for guiding the traction section so that the traction section changes direction between the extension and retraction direction along the charging arm 2 and the extension and retraction direction perpendicular to the charging arm 2.
[0060] In other words, in this embodiment, the sliding direction of the opening / closing door 12 is perpendicular to the movement direction of the charging arm 2. This embodiment uses guide pulleys 14 to guide and limit the traction section, ensuring that the part of the traction section near the opening / closing door 12 can generate a pulling force parallel to the sliding direction of the opening / closing door 12, ensuring that the opening / closing door 12 slides smoothly. At the same time, it ensures that the part of the traction section connected to the charging arm 2 can move in the same direction as the charging arm 2. This makes the movement of the flexible traction member 4 smoother and more stable, and the operation of the opening / closing door 12 smoother.
[0061] It should be noted that the above embodiments do not limit the specific structure and working principle of the energy storage device 3, as long as it can drive the opening and closing door 12 to open.
[0062] In some embodiments, the energy storage component 3 includes a first elastic element or a magnetic element. In some embodiments, the first elastic element may be a spring, and the magnetic element may be a magnet, etc.
[0063] When the energy storage component 3 includes the first elastic element, when the opening and closing door 12 is closed, the first elastic element is in a compressed or stretched state, thereby giving the first elastic element an elastic force. Therefore, when the flexible traction component 4 moves toward the opening and closing door 12 as the charging arm 2 extends, the elastic force of the first elastic element is used to open the opening and closing door 12.
[0064] When the energy storage component 3 includes a magnetic component, the magnetic component possesses magnetic force. When the flexible traction component 4 extends along with the charging arm 2 and moves towards the opening / closing door 12, the magnetic force of the magnetic component opens the opening / closing door 12. For example, the opening / closing door 12 includes a first door body 121 and a second door body 122. Corresponding positions of the first door body 121 and the second door body 122 are respectively provided with magnetic components of the same magnetic properties. Thus, when the flexible traction component 4 extends along with the charging arm 2 and moves towards the opening / closing door 12, the like poles of the magnetic components of the first door body 121 and the second door body 122 repel each other, causing the first door body 121 and the second door body 122 to move in opposite directions, thereby opening the opening / closing door 12.
[0065] Further, in some embodiments, the two ends of the opening and closing door 12 are respectively provided with the energy storage member 3 along the direction perpendicular to the movement direction of the opening and closing door 12.
[0066] That is, by respectively providing the energy storage member 3 at the two ends of the opening and closing door 12 along the direction perpendicular to the movement direction of the opening and closing door 12, the opening and closing door 12 is opened by the combined action of the energy storage members 3 at the two ends of the opening and closing door 12, which can ensure that the opening and closing door 12 is more evenly stressed and more smoothly opened.
[0067] In addition, in order to avoid excessive stretching of the flexible traction member 4 when it is stretched to the limit, please refer to Figure 4 and Figure 7 In some embodiments, the first transmission section 43 is connected with a second elastic member 5, and the opening and closing door 12 is provided with a limiting groove for accommodating the second elastic member 5.
[0068] That is, the second elastic member 5 is arranged at the position where the first transmission section 43 is connected with the opening and closing door 12, and the connection between the first transmission section 43 and the opening and closing door 12 is realized by the cooperative connection of the second elastic member 5 and the limiting groove. In this case, when the charging arm 2 is retracted and the first transmission section 43 drives the opening and closing door 12 to close, the second elastic member 5 can be elastically deformed to absorb further tension when the flexible traction member 4 is stretched to the limit, which is beneficial to improve the reliability of the flexible traction member 4 and prevent the flexible traction member 4 from being broken due to excessive stretching.
[0069] It should be noted that the specific structure of the second elastic member 5 is not limited in the embodiment, and in some embodiments, the second elastic member 5 includes a spring.
[0070] Further, in order to improve the stability of the second elastic member 5 when it is compressed, as shown in Figure 4 and Figure 7 In some embodiments, the end of the second elastic member 5 away from the first transmission section 43 is connected with a sliding block 6, and the sliding block 6 is in sliding cooperation with the limiting groove.
[0071] That is, by arranging the slidable sliding block 6 in the limiting groove, the sliding block 6 is connected with the second elastic member 5, and the compression direction of the second elastic member 5 is limited by the cooperation of the sliding block 6 and the limiting groove, which avoids the second elastic member 5 from being skewed and improves the stability of the second elastic member 5 when it is compressed, ensuring the stability and reliability of the overall structure.
[0072] It can be understood that the charging arm 2 includes an arm body 21 and a charging gun head 22 connected with the arm body 21 for electrical connection with a power receiving seat, and the end of the arm body 21 away from the charging gun head 22 is connected with a driving mechanism 7 for driving the charging arm 2 to extend and retract. The charging gun head 22 includes a charging interface to be electrically connected with a power receiving interface of a power receiving device to realize charging.
[0073] It should also be noted that the relational terms herein, such as first and second, and the like, are used solely to distinguish one from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions.
[0074] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.
