Description

Technical Field

[0001] The utility model relates to the technical field of automatic charging, and more specifically, to an electric charging stand. In addition, the utility model also relates to an automatic charging system comprising the electric charging stand. Background Art

[0002] With the development of automatic charging technology, automatic charging systems are widely used in various industries. Automatic charging systems include a charging station and an automatic charging device.

[0003] The power receiving stand is provided with a power receiving interface. In order to protect the interior of the power receiving stand, an opening and closing door is provided near the power receiving interface of the power receiving stand. When charging is required, the opening and closing door opens to allow the charging arm of the automatic charging device to connect with the power receiving interface. When charging is completed and the charging arm withdraws from the power receiving interface, the opening and closing door closes to protect the power receiving interface.

[0004] In the related art, the door opening and closing action is driven by a motor or manually to open or close the door. However, the motor-driven method is not only costly, but also easily susceptible to signal interference and unable to open or close the door smoothly. Manually opening or closing the door carries the risk of accidentally touching the door, causing the power interface to be opened, resulting in low protection reliability of the power interface.

[0005] Therefore, how to provide a low-cost and highly reliable power receiving seat for opening and closing the door is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of the present invention is to provide a power receiving stand, the door opening and closing action of which has low cost and high reliability.

[0007] Another object of the present invention is to provide an automatic charging system comprising the above-mentioned receiving stand, wherein the cost of opening and closing the door of the receiving stand is low and the reliability is high.

[0008] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0009] A power receiving seat, comprising:

[0010] The receiving seat body is provided with an accommodating channel, one end of the accommodating channel is provided with a first opening for the charging arm to enter, the other end is provided with a second opening, and the side wall of the accommodating channel is provided with a third opening;

[0011] An opening and closing door is movably provided on the power receiving seat body and is used to open or close the second opening;

[0012] a toggle member rotatably disposed on the receiving seat body, comprising a pressure-bearing portion and a transmission portion, wherein the pressure-bearing portion extends from the third opening into the accommodating channel, and the transmission portion is linked to the opening and closing door to open the opening and closing door when the charging arm pushes against the pressure-bearing portion;

[0013] The energy storage component is connected between the receiving seat body and the opening and closing door, and is used to close the opening and closing door when the charging arm withdraws from the accommodating channel.

[0014] Optionally, when the opening and closing door is opened, the pressure-bearing portion blocks the third opening.

[0015] Optionally, the pressure-bearing portion and the transmission portion are respectively located on both sides of the rotating shaft of the toggle member, and the distance from the transmission portion to the rotating shaft is greater than the distance from the pressure-bearing portion to the rotating shaft.

[0016] Optionally, a flexible traction member is connected between the transmission part and the opening and closing door.

[0017] Optionally, the opening and closing door is slidably provided on the power receiving seat body, and the power receiving seat body is further provided with a guide pulley, and the guide pulley is used to guide the flexible traction member.

[0018] Optionally, an anti-line-off stopper is provided at a position of the power receiving seat body corresponding to the guide pulley, so as to prevent the flexible traction member from being separated from the guide pulley.

[0019] Optionally, the opening and closing door includes a first door body and a second door body arranged opposite to each other; and the energy storage component includes:

[0020] A first elastic member is provided between the upper and lower ends of the first door body and the second door body and the power receiving seat body respectively; and / or,

[0021] The magnetically attractive magnetic members are respectively provided on the first door body and the second door body, and are used to adsorb and fix the first door body and the second door body when the first elastic member drives the first door body and the second door body to close.

[0022] Optionally, the power receiving seat body is provided with a locking mechanism for locking the opening and closing door when the toggle member rotates abnormally and when the opening and closing door is manually opened to a preset position; the opening of the opening and closing door corresponding to the preset position is greater than the opening when the opening and closing door is opened by the toggle member.

[0023] An automatic charging system comprises any one of the above-mentioned power receiving seats and an automatic charging device for charging the power receiving seat, wherein the automatic charging device comprises a charging arm.

[0024] Optionally, the charging arm is connected to a driving mechanism, and the driving mechanism is provided with an over-torque protection device, which is used to drive the charging arm to withdraw from the accommodating channel of the electric receiving seat when the driving mechanism is unable to drive the charging arm to drive the toggle member of the electric receiving seat to open the opening and closing door of the electric receiving seat.

[0025] The power receiving seat provided by the utility model has the following beneficial effects:

[0026] When it is necessary to charge a device equipped with the power receiving socket, the charging arm of the automatic charging device is inserted into the receiving channel from the first opening and moves along the receiving channel toward the second opening. During this process, the charging arm contacts and pushes against the pressure-bearing portion of the toggle member, causing the toggle member to rotate, which in turn causes the transmission portion of the toggle member to drive the opening and closing door to open, thereby leaving the second opening open. This allows the charging arm to enter the power receiving interface of the power receiving socket after reaching the second opening to charge the device. When charging is complete, the charging arm exits the receiving channel. At this time, the energy storage member causes the opening and closing door to close, thereby closing the second opening and protecting the power receiving interface.

[0027] As can be seen, the electric receiver utilizes the power of the plug gun when the charging arm is extended to open the door, and utilizes the energy storage element to close the door. There is no need to provide a dedicated power source (such as a motor drive mechanism in the related art) to open and close the door, nor is there a need to manually open or close the door. Therefore, the electric receiver achieves the door opening and closing action without additional power, simplifies the start and stop steps of the door opening and closing action, reduces the cost of the door opening and closing action, and makes the door opening and closing action less susceptible to interference. Furthermore, it can also prevent the door from being abnormally opened due to human error, resulting in high reliability. Furthermore, because the toggle member has a pressure-bearing portion that extends into the accommodating channel, the structure of the charging arm itself can be used to directly drive the toggle member to rotate, eliminating the need for a dedicated trigger member to trigger the toggle member's rotation. This results in a simple and compact structure.

[0028] The automatic charging system provided by the utility model includes the above-mentioned power receiving seat and has the same beneficial effects as the above-mentioned power receiving seat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The core of the present invention is to provide a charging station with low cost and high reliability in opening and closing the door. Another core of the present invention is to provide an automatic charging system including the above-mentioned charging station with low cost and high reliability in opening and closing the door.

[0042] Please refer to Figures 1 to 4The embodiment of the utility model provides a power receiving seat, including a power receiving seat body 1, an opening and closing door 2, a toggle member 3 and an energy storage member 4. The power receiving seat body 1 is provided with a receiving channel 11, one end of the receiving channel 11 is provided with a first opening 111, the other end is provided with a second opening 112, and the side wall of the receiving channel 11 is provided with a third opening 113; the first opening 111 is used for the charging arm 9 to enter the receiving channel 11, and the second opening 112 is close to the charging interface of the power receiving seat; the opening and closing door 2 can be movably arranged on the receiving The power socket body 1 is used to open or close the second opening 112; the toggle member 3 is rotatably provided on the receiving socket body 1, and the toggle member 3 includes a pressure-bearing part 31 and a transmission part 32. The pressure-bearing part 31 extends into the accommodating channel 11 from the third opening 113, and the transmission part 32 is linked with the opening and closing door 2 to open the opening and closing door 2 when the charging arm 9 pushes the pressure-bearing part 31; the energy storage member 4 is connected between the receiving socket body 1 and the opening and closing door 2, and is used to close the opening and closing door 2 when the charging arm 9 withdraws from the accommodating channel 11.

[0043] When it is necessary to charge the device installed with the power receiving seat, the charging arm 9 of the automatic charging device is inserted into the accommodating channel 11 from the first opening 111 and moves along the accommodating channel 11 in the direction close to the second opening 112. During this process, the charging arm 9 contacts the pressure-bearing part 31 of the toggle member 3 and pushes against the pressure-bearing part 31, thereby rotating the toggle member 3, and then the transmission part 32 of the toggle member 3 drives the opening and closing door 2 to open, so that the second opening 112 is in an open state, so that the charging arm 9 can enter the power receiving interface of the power receiving seat after reaching the second opening 112 to charge the device. When charging is completed, the charging arm 9 withdraws from the accommodating channel 11. At this time, under the action of the energy storage member 4, the opening and closing door 2 is closed, so that the second opening 112 is in a closed state to protect the power receiving interface.

[0044] As can be seen, the electric receiver utilizes the power of the gun when the charging arm 9 is extended to open the door 2, and utilizes the energy storage element 4 to close the door 2. There is no need to provide a dedicated power source (such as a motor drive mechanism in the related art) to open and close the door 2, nor is there a need to manually open or close the door 2. Therefore, the electric receiver achieves the goal of driving the door 2 without additional power, simplifying the start and stop steps of the door 2, reducing the cost of the door 2 operation, and making the door 2 less susceptible to interference. Furthermore, it can also prevent human error from causing the door 2 to open abnormally, resulting in high reliability. Furthermore, because the toggle member 3 has a pressure-bearing portion 31 that extends into the accommodating channel 11, the structure of the charging arm 9 itself can be used to directly drive the toggle member 3 to rotate, eliminating the need for a dedicated trigger member to trigger the toggle member 3's rotation. This results in a simple and compact structure.

[0045] Furthermore, when charging on rainy days, to prevent moisture and other foreign matter from entering the receiving socket through the third opening 113, in some embodiments, when the door 2 is open, the pressure-bearing portion 31 blocks the third opening 113. That is, when the charging arm 9 pushes against the pressure-bearing portion 31 to rotate the toggle member 3, thereby fully opening the door 2, the pressure-bearing portion 31 can block the third opening 113. This helps prevent rainwater and other foreign matter from entering the receiving socket through the third opening 113 during charging, thereby improving the protective effect.

[0046] Furthermore, in some embodiments, when the door 2 is opened and the pressure-bearing portion 31 blocks the third opening 113, the side of the pressure-bearing portion 31 facing the interior of the accommodating channel 11 is flush with the inner wall of the accommodating channel 11 (e.g., Figure 4 As shown), that is, the pressure-bearing portion 31 becomes a part of the inner wall of the accommodating channel 11, which can further enhance the waterproof effect and can make the inner diameter of the accommodating channel 11 relatively small, which is conducive to making the structure compact.

[0047] In addition, in order to enable the toggle member 3 to drive the door 2 to open to a larger opening at a smaller angle, such as Figure 3 As shown, in some embodiments, the pressure-bearing portion 31 and the transmission portion 32 are respectively located on both sides of the rotating shaft 33 of the toggle member 3 , and the distance from the transmission portion 32 to the rotating shaft 33 is greater than the distance from the pressure-bearing portion 31 to the rotating shaft 33 .

[0048] In other words, this embodiment utilizes the principle of leverage, allowing the pressure-bearing portion 31 to have a relatively small displacement, while the transmission portion 32 can have a relatively large displacement. This allows the transmission portion 32 to drive the door 2 to have a relatively large stroke, thereby ensuring that the door 2 is fully opened with a relatively small rotation angle of the toggle member 3. This helps to reduce the range of motion of the toggle member 3 and save space.

[0049] Furthermore, in order to facilitate the connection between the transmission part 32 and the opening and closing door 2, as shown in FIG. Figure 1 and Figure 2 As shown, in some embodiments, a flexible traction member 5 is connected between the transmission part 32 and the opening and closing door 2.

[0050] That is, in this embodiment, the toggle member 3 and the door 2 are connected via the flexible traction member 5, thereby converting the rotation of the toggle member 3 into the opening and closing movement of the door 2. It will be appreciated that the flexible traction member 5 is flexible and can deform into any shape, thereby facilitating the positioning of the toggle member 3 and the door 2 according to spatial layout requirements. The flexible traction member 5 can achieve the connection between the toggle member 3 and the door 2 by deforming into any shape.

[0051] It should be noted that the present embodiment does not limit the specific material and structure of the flexible traction member 5, as long as the flexible traction member 5 is flexible and can produce any deformation, and has a certain structural strength to ensure that a reliable pulling force is generated on the door 2. In some embodiments, the flexible traction member 5 includes a nylon rope or a steel wire rope.

[0052] In addition, the above embodiment does not limit the specific movement mode of the opening and closing door 2, as long as the opening and closing door 2 can be opened. The opening and closing door 2 can be opened by sliding, rotating, or moving in a plane.

[0053] like Figure 2 As shown, in some embodiments, the opening and closing door 2 is slidably provided on the power receiving seat body 1 , and the power receiving seat body 1 is further provided with a guide pulley 6 , which is used to guide the flexible traction member 5 .

[0054] That is, in this embodiment, the door 2 is opened or closed by sliding. This movement is simple and occupies little space in a direction perpendicular to the door 2, thus facilitating a compact structure. Furthermore, in this embodiment, by providing a guide pulley 6, which guides and limits the flexible traction member 5, the portion of the flexible traction member 5 proximate the door 2 can exert a pulling force on the door 2 parallel to the sliding direction of the door 2, thereby ensuring smooth sliding of the door 2.

[0055] Further, if Figure 2 As shown, in some embodiments, an anti-offline stopper 7 is provided at a position corresponding to the guide pulley 6 of the power receiving seat body 1 , and the anti-offline stopper 7 is used to prevent the flexible traction member 5 from being separated from the guide pulley 6 .

[0056] That is to say, this embodiment provides an anti-de-line stopper 7 at the guide pulley 6, so that the anti-de-line stopper 7 acts as a stop and limiter for the flexible traction member 5 at the guide pulley 6, preventing the flexible traction member 5 from detaching from the guide pulley 6, thereby improving the reliability of the flexible traction member 5 and the correctness of the movement direction.

[0057] It should be noted that this embodiment does not limit the specific structure and installation method of the anti-line-off stopper 7, as long as it can prevent the flexible traction member 5 from being separated from the guide pulley 6.

[0058] In addition, the above embodiments do not limit the specific structure and working principle of the energy storage component 4, as long as the energy storage component 4 can drive the openable door 2 to close.

[0059] Considering the simplicity of structure and convenience of setting, Figure 2As shown, in some embodiments, the opening and closing door 2 includes a first door body 21 and a second door body 22 arranged opposite to each other; the energy storage component 4 includes a first elastic component, which is arranged between the upper and lower ends of the first door body 21 and the second door body 22 and the power receiving seat body 1 respectively.

[0060] That is, this embodiment utilizes the first elastic member to drive the opening and closing door 2 to close. It can be understood that when the opening and closing door 2 is opened, the opening and closing door 2 squeezes the first elastic member, causing the first elastic member to store elastic force. When the charging arm 9 withdraws from the accommodating channel 11, the elastic force of the first elastic member drives the opening and closing door 2 to close. In addition, the first elastic member is respectively arranged between the upper and lower ends of the first door body 21 and the second door body 22 and the receiving seat body 1. That is, the first elastic member is provided at the upper and lower ends of the first door body 21 and the upper and lower ends of the second door body 22. This is conducive to making the first door body 21 and the second door body 22 bear force evenly, ensuring the smooth movement of the first door body 21 and the second door body 22 when closing.

[0061] Furthermore, in some embodiments, the energy storage member 4 also includes a magnetic member that is magnetically attracted to each other, and the magnetic member is respectively provided on the first door body 21 and the second door body 22, and is used to adsorb and fix the first door body 21 and the second door body 22 when the first elastic member drives the first door body 21 and the second door body 22 to close.

[0062] That is to say, when the first door body 21 and the second door body 22 are closed under the elastic force of the first elastic member, the magnetic attraction force of the magnetic member is used to adsorb and fix the first door body 21 and the second door body 22, so that the first door body 21 and the second door body 22 can be closed and reset more accurately, thereby improving the reliability of the closed state of the opening and closing door 2.

[0063] In addition, in order to prevent the door 2 from being unable to open normally and affecting charging when the toggle member 3 and / or the flexible traction member 5 are damaged or stuck, in some embodiments, the receiving socket body 1 is provided with a locking mechanism, which is used to lock the door 2 when the toggle member 3 rotates abnormally and when the door 2 is manually opened to a preset position; the opening of the door 2 corresponding to the preset position is greater than the opening when the door 2 is opened by the toggle member 3.

[0064] In other words, the addition of the locking mechanism in this embodiment is equivalent to adding an emergency device. When the toggle member 3 rotates abnormally, causing the door 2 to be unable to open normally, a person can manually reach into the receiving channel 11 through the first opening 111 and forcibly push the door 2 to the locking position of the locking mechanism, causing the door 2 to be locked by the locking mechanism. This temporarily places the door 2 in a normally open state, facilitating charging of the device in an emergency without affecting user use. After maintenance personnel have repaired the toggle member 3 and / or the flexible traction member 5, they can release the locking mechanism from the door 2. It is understandable that because the opening of the door 2 when the locking mechanism locks the door 2 is greater than the opening when the toggle member 3 is driven to open the door 2, during normal use, when the toggle member 3 is used to drive the door 2 to open, the door 2 does not move to the locking position of the locking mechanism. Therefore, the presence of the locking mechanism does not affect the opening of the door 2 during normal use of the toggle member 3.

[0065] It should be noted that this embodiment does not limit the specific structure of the locking mechanism, as long as the locking mechanism can lock the openable door 2.

[0066] Please refer to Figures 5 to 8 In some embodiments, the locking mechanism includes a mounting seat, a positioning pin 8, a second elastic member, and an unlocking member. The mounting seat is used to be installed on the power receiving seat body 1. The positioning pin 8 is slidably arranged on the mounting seat. The second elastic member is connected between the positioning pin 8 and the mounting seat. The unlocking member is rotatably connected to the mounting seat, and the unlocking member is linked to the positioning pin 8. Under no-force conditions, the positioning pin 8 is in an extended state under the action of the second elastic member. When the positioning pin 8 is subjected to force, the unlocking member is driven to rotate relative to the mounting seat. When the unlocking member is subjected to force, the positioning pin 8 is driven to retract. In addition, the opening and closing door 2 is provided with a limiting groove 211 (such as Figure 8 shown).

[0067] That is, when the positioning pin 8 is subjected to a compressive force, the positioning pin 8 retracts. Simultaneously, the positioning pin 8 compresses the second elastic member, imparting an elastic force to the second elastic member and causing the unlocking member to rotate relative to the mounting base to allow the positioning pin 8 to retract. When the compressive force on the positioning pin 8 is removed, the positioning pin 8 extends under the elastic force of the second elastic member. Therefore, when the toggle member 3 and / or the flexible traction member 5 are damaged or stuck, the door 2 can be manually opened until the door 2 compresses the positioning pin 8, causing it to retract. When the door 2 is opened until the retaining groove 211 aligns with the positioning pin 8, the elastic force of the second elastic member causes the positioning pin 8 to spring into the retaining groove 211, thereby locking the door 2. After repairing the toggle member 3 and / or the flexible traction member 5, the unlocking member can be manually actuated to cause the unlocking member to retract the positioning pin 8, thereby releasing the lock on the door 2 and allowing the door 2 to close under the action of the energy storage member 4.

[0068] In addition to the above-mentioned power receiving seat, the present invention also provides an automatic charging system including the power receiving seat disclosed in the above-mentioned embodiment. The automatic charging system also includes an automatic charging device for charging the power receiving seat. The automatic charging device includes a charging arm 9. For the structures of other parts of the power receiving seat and the automatic charging device, please refer to the relevant technology and will not be repeated in this article.

[0069] The key point of this embodiment is that the automatic charging system includes the power receiving seat disclosed in any one of the above embodiments, and has the same beneficial effects as the above power receiving seat, which will not be repeated here.

[0070] In some embodiments, the charging arm 9 is connected to a driving mechanism, and the driving mechanism is provided with an over-torque protection device, which is used to drive the charging arm 9 to exit the accommodating channel 11 of the electric seat when the driving mechanism cannot drive the charging arm 9 to drive the toggle member 3 of the electric seat to open the opening and closing door 2 of the electric seat.

[0071] That is, this embodiment utilizes a drive mechanism to drive the charging arm 9 to extend or retract. When the charging arm 9 is extended and the door 2 is not opened normally, the charging arm 9 will counteract the door 2. At this time, the torque of the driving mechanism will increase. In this case, the over-torque protection device will come into play. When the torque of the driving mechanism reaches the over-torque protection setting value of the over-torque protection device, the driving mechanism is controlled to retract the charging arm 9, so that the charging arm 9 exits the receiving seat accommodating channel 11 to prevent the charging arm 9 from impacting the door 2 and causing damage to the door 2. In other words, by providing an over-torque protection device, this embodiment allows the charging arm 9 to automatically retract when the door 2 cannot open normally.

[0072] It should be noted that this embodiment does not limit the specific size of the over-torque protection setting value of the over-torque protection device. Those skilled in the art can set it according to actual needs. What needs to be ensured is that the over-torque protection setting value is less than the impact resistance parameter value of the opening and closing door 2 to ensure that the opening and closing door 2 is not damaged.

[0073] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0074] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0075] The above describes in detail the charging station and automatic charging system provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
