Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic storage batteries, and particularly relates to an automatic plugging device for a photovoltaic storage battery vehicle and an electricity consumption bin. Background Art

[0002] Against the backdrop of the accelerating global energy structure transformation towards renewable energy, the photovoltaic-storage integrated system, with its characteristics of converting solar energy into electrical energy and enabling flexible storage and allocation, has become a key technical path to promote the green development of energy. As a mobile energy storage unit in the photovoltaic-storage integrated system, the photovoltaic storage battery vehicle can achieve flexible transportation and distribution of electrical energy and can be widely applied to scenarios such as emergency power supply, distributed energy access, and power supply guarantee in remote areas. However, the efficiency and stability of the electrical energy transmission between the photovoltaic storage battery vehicle and the electricity consumption bin have become the core bottleneck restricting its large-scale application.

[0003] The electricity consumption bin is a terminal facility for power reception and use, which can provide power support for surrounding areas, equipment, etc. When cooperating with the photovoltaic storage battery vehicle, the electricity consumption bin is connected to the photovoltaic storage battery vehicle through an automatic plugging device to receive the electrical energy transported by the battery vehicle and meet the electricity consumption needs of itself and related areas. A patent with the Chinese invention patent publication number CN104934767A discloses a rotary self-locking pin electrical connection device, its socket, and its plug, belonging to the field of conductive connection devices. At least one plug self-locking part is provided on the side wall of the plugging bolt of the plug, and the plug self-locking part is a round hole, or a groove or bump with a curved surface structure; a socket self-locking part corresponding to the plug self-locking part is provided in the jack of the socket, and the socket self-locking part locks the plug after the plug rotates a preset angle. The socket self-locking part has a retractable locking part with a protruding or concave curved surface structure or a round hole, and the locking part cooperates with the plug self-locking part to achieve automatic locking of the plug; the socket has an insertion position where the plug can be inserted and an energized position where the plug and the socket are in contact and energized after rotating a preset angle from the insertion position. When the invention rotates and energizes, it is easy to apply force, and the self-locking effect is stable and reliable; there is only a rotatable plugging notch on the socket panel of the present invention, and the plug can be directly pulled out at the energized position, and the power-off is faster.

[0004] However, the above technologies often have the following defects: When used in the connection scenario between the photovoltaic storage battery vehicle and the electricity consumption bin, during the connection process between the photovoltaic storage battery vehicle and the electricity consumption bin, the docking process has high requirements. And this rotary self-locking connection device requires manual guidance for the plug to be inserted and manual rotation to achieve connection, still relying on manual assistance. Moreover, during the manual operation process, the alignment deviation between the plug and the socket may be caused by human operation errors, affecting subsequent electrical energy transmission. Any looseness in the electrical energy transmission in its photovoltaic storage system may cause poor contact, resulting in a decrease in the electrical energy transmission efficiency.

[0005] To this end, the present invention provides an automatic plugging device for a photovoltaic storage battery vehicle and an electrical storage bin. Summary of the Invention

Outside the electrical interface, a plugging housing is fixedly installed. The outer arc surface of the electrical interface is sleeved with a conical housing. In the middle section of the outer arc surface of the conical housing, there is an arc-shaped abutting surface. At one end of the arc-shaped abutting surface near the electrical interface, there is a bent section. The upper surface of the bent section is placed in the inner side wall of the electrical interface. Between the arc-shaped abutting surface and the bent section, a contact member is movably sleeved. At one end of the contact member close to the bent section, there is a abutting end. On the side of the contact member away from the abutting end, there is an elastic bow surface. Between the abutting end and the elastic bow surface, there is a support portion. On the support portion of the outer arc surface of the contact member, a locking assembly is adhesively connected. The locking assembly includes radial connecting ribs sleeved in the inner arc surface of the conical housing. In the inner arc surface of the radial connecting ribs, there is a deformation cavity.

[0008] On one side of the outer arc surface of the radial connecting ribs, there is an opening. The top of the outer arc surface of the radial connecting ribs is in contact with the inner arc surface of the arc-shaped abutting surface. At the bottom of the outer arc surface of the radial connecting ribs, a tight tongue is abutted.

[0009] On the tight tongue, near the bottom of the outer arc surface of the radial connecting ribs, there is a pressing surface. At the end of the tight tongue away from the pressing surface, there is a pressing-down end. At the top of the pressing-down end, there is an extending elastic surface connected.

[0010] The lower surface of the pressing-down end is placed on the top of the elastic bow surface. Plugging grooves are provided on the outer arc surfaces of both the contact member and the tight tongue. The two plugging grooves are in the same plane.

[0011] The bottom surface of the elastic bow surface in the contact member abuts against the half-body joint. The outer arc surface of the half-body joint is sleeved with a plugging assembly. The plugging assembly includes a positioning support sleeved on the outer arc surface of the half-body joint. On both sides of the front surface of the positioning support, auxiliary holes are provided.

[0012] On both sides of the positioning support, there are elastic arms. One end of the elastic arms is placed in the inner bottom wall of the electrical interface. The outer arc surface of the elastic arms abuts against the inner side wall of the electrical interface.

[0013] The inner arc surface of the auxiliary hole is movably sleeved with a plug socket. The outer arc surface of the plug socket is provided with an outer flange, and one side surface of the outer flange is placed on the back surface of the positioning support.

[0014] One end of the plug socket is provided with a connecting section. One side of the connecting section is provided with an inner groove. The inner arc surface of the inner groove is fixedly installed with a spring. A bearing end is arranged at the connection between the plug socket and the spring.

[0015] The end face of the bearing end is fixedly connected to the spring. The other end of the spring is fixedly installed with a sliding sleeve.

[0018] 2. Through the precise guiding structure composed of the bent section and the arc-shaped abutting surface of the conical shell, and the coordinated action of the contact piece, the locking component and the plugging component, it is ensured that the plug component can be precisely inserted into the power consumption interface. The shrinkage and clamping force generated by the locking component on the contact piece, and the double locking structure formed by the plugging component reduce the contact resistance to an extremely low level, ensuring the stable and efficient transmission of electric energy, reducing power loss, and improving the overall energy efficiency of the photovoltaic energy storage system.

[0019] 3. When the plug is inserted, the elastic arm undergoes elastic deformation to abut against the inner side wall of the power consumption interface, which not only plays a role in precise positioning, but also effectively buffers the impact force during plug insertion and protects the internal connection components. At the same time, the deformation cavity is automatically activated after the plug is inserted in place, quickly filling the interface gap, isolating external dust and water vapor, and preventing electric leakage, providing all-round safety protection for the electric energy transmission process, and reducing the equipment failure risk and potential safety hazards.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] Such as Figure 1 , Figure 2 and Figure 3As shown in the figure, the embodiment of the present invention includes a docking frame 1. At the top of the front surface of the docking frame 1, there is an electrical interface 2. Inside the inner side wall of the electrical interface 2, a half-body connector 3 is fixedly installed. Outside the electrical interface 2, a plugging housing 4 is fixedly installed. An outer arc surface of the electrical interface 2 is sleeved with a conical housing 5. In the middle section of the outer arc surface of the conical housing 5, there is an arc-shaped abutting surface 51. At one end of the arc-shaped abutting surface 51 near the electrical interface 2, there is a bent section 52. The upper surface of the bent section 52 is placed in the inner side wall of the electrical interface 2. Between the arc-shaped abutting surface 51 and the bent section 52, a contact member 6 is movably sleeved. At one end of the contact member 6 close to the bent section 52, there is a abutting end 61. On one side of the contact member 6 far from the abutting end 61, there is an elastic bow surface 62. Between the abutting end 61 and the elastic bow surface 62, there is a supporting portion. On the supporting portion of the outer arc surface of the contact member 6, a locking assembly 7 is fitted and connected. The locking assembly 7 includes a radial connecting rib 71 sleeved in the inner arc surface of the conical housing 5. In the inner arc surface of the radial connecting rib 71, there is a deformation cavity 72.

[0025] In the initial state, the docking frame 1 is installed at a suitable position in the electrical storage bin, and the electrical interface 2 is exposed. The half-body connector 3, the plugging housing 4, the conical housing 5, the contact member 6, the locking assembly 7, and the plugging assembly 8 are all in an unoperated state. At this time, the arc-shaped abutting surface 51 of the conical housing 5 and the bent section 52 together form a guiding structure. The special curved surface design of the bent section 52 guides the direction for the subsequent plug docking. The abutting end 61 of the contact member 6 is placed on the inner side wall of the electrical interface 2, and the elastic bow surface 62 maintains its natural curvature. In the locking assembly 7, the radial connecting rib 71 fits the inner arc surface of the conical housing 5, and the locking tongue 73 extends freely. Each component cooperates with each other to form a stable initial structure.

[0026] During the photovoltaic power generation stage, the photovoltaic panels carried on the photovoltaic energy storage vehicle convert the absorbed solar energy into electrical energy through the photovoltaic conversion principle, and the electrical energy is stably stored in the battery pack inside the battery vehicle through the on-vehicle charging management system. When there is an electrical demand in the electrical storage bin, a truck is used to transport the fully charged photovoltaic energy storage vehicle to the location of the electrical storage bin. A plurality of laser positioning piles are installed at the entrance and surrounding areas of the electrical storage bin. The laser receiver on the battery vehicle receives the laser signals emitted by the positioning piles, calculates the relative position and angular deviation between the battery vehicle and the electrical storage bin through the on-vehicle control system, and adjusts the driving direction and speed of the battery vehicle in real time, so that the battery vehicle can accurately drive into the electrical storage bin. At the same time, guiding wheels can be provided at the bottom of the battery vehicle to cooperate with the guiding track preset on the ground of the electrical storage bin, further ensuring that the battery vehicle can move along an accurate path, realizing precise alignment with the electrical interface 2. The automatic plugging and separation processes are all automatically executed by the battery vehicle, and the operation process is simple and clear, reducing the work intensity and skill requirements of the operators.

[0027] As the plug is inserted deeper, the reserved liquid cooling connection port inside the plug will be accurately docked with the pipeline interface of the liquid cooling mechanism in the power consumption compartment. When the plug is inserted in place, the pipelines in the liquid cooling mechanism in the power consumption compartment are seamlessly connected to the liquid cooling channels in the mobile battery vehicle. At this time, the circulation pump starts, and the coolant begins to flow in the liquid cooling circulation system of the battery vehicle and the power consumption compartment. During the power transmission process, the heat generated by the battery pack and the conductive components is absorbed and carried away by the coolant in the liquid cooling channels. After being dissipated by the radiator in the power consumption compartment, the low-temperature coolant flows back into the battery vehicle again, forming an efficient heat dissipation cycle to ensure that the battery vehicle maintains an appropriate temperature during operation and avoid affecting the battery performance and service life due to overheating.

[0028] When the battery vehicle moves near the power consumption interface 2, the automatic plugging process starts. The plug component on the battery vehicle gradually approaches the power consumption interface 2 under the push of the driving device. The plug first contacts the bent section 52 of the conical housing 5. The curved surface design of the bent section 52 plays a secondary guiding role, guiding the plug to smoothly enter the power consumption interface 2 along the arc-shaped abutting surface 51 of the conical housing 5. During the plug pushing process, the contact member 6 is squeezed, and the contact member 6 moves along the arc-shaped abutting surface 51 in a direction away from the power consumption interface 2, and the elastic bow surface 62 deforms. (According to Hooke's law), the deformation of the elastic bow surface 62 generates a strong elastic restoring force, and the generated thrust acts on the lower pressing end 75 of the clamping tongue 73. The clamping tongue 73 rotates around the connection point with the radial connecting rib 71, and the pressing surface 74 gradually fits with the outer arc surface of the radial connecting rib 71. Locking or releasing is achieved through their relative movement. The actual rotating part is the clamping tongue 73, rather than the radial connecting rib 71. The radial connecting rib 71 serves as a fixed fulcrum, providing a rotation point for the clamping tongue 73. When the plug is inserted, the contact member 6 is squeezed, and its elastic bow surface 62 deforms to generate a thrust, which acts on the lower pressing end 75 of the clamping tongue 73. The clamping tongue 73 and the radial connecting rib 71 use the hinged position as the rotation fulcrum. The clamping tongue 73 uses the lower pressing end 75 as the force application point and the hinge point as the fulcrum, and rotates towards the outer arc surface of the radial connecting rib 71, causing the pressing surface 74 to gradually fit the outer arc surface, driving the locking assembly 7 to contract, realizing radial locking. As the fulcrum, the radial connecting rib 71 must remain stationary to convert the thrust of the contact member 6 into the rotation torque of the clamping tongue 73 through the lever principle. The structure at the opening 78 undergoes elastic deformation, and the entire locking assembly 7 generates a contraction and clamping force on the contact member 6, tightly pressing the contact member 6 against the surface of the plug component, achieving close contact between the plug and the contact member 6 and effectively reducing the contact resistance.

[0029] Such as Figure 4 , Figure 7 and Figure 8As shown, the bottom surface of the elastic bow surface 62 in the contact member 6 abuts against the half-body joint 3. An insertion component 8 is sleeved on the outer arc surface of the half-body joint 3. The insertion component 8 includes a positioning support 81 sleeved on the outer arc surface of the half-body joint 3, and auxiliary holes 82 are formed on both sides of the front surface of the positioning support 81.

[0030] Elastic arms 83 are provided on both sides of the positioning support 81. One end of each elastic arm 83 is placed in the inner bottom wall of the electrical interface 2, and the outer arc surface of the elastic arm 83 abuts against the inner side wall of the electrical interface 2. An insertion sleeve 84 is movably sleeved on the inner arc surface of the auxiliary hole 82. An outer flange 841 is provided on the outer arc surface of the insertion sleeve 84. One side surface of the outer flange 841 is placed on the back surface of the positioning support 81. A connection section 842 is provided at one end of the insertion sleeve 84. An inner groove 843 is provided on one side of the connection section 842. A spring 85 is fixedly installed on the inner arc surface of the inner groove 843. A bearing end 844 is provided at the connection between the insertion sleeve 84 and the spring 85. The end surface of the bearing end 844 is fixedly connected to the spring 85. The other end of the spring 85 is fixedly installed with a sliding sleeve 86. An introduction surface 861 is provided on the inner arc surface of the sliding sleeve 86. The number of insertion sleeves 84 is two, and they are symmetrically distributed in the two auxiliary holes 82 in a mirror image. Heat dissipation holes are formed on the outer arc surface of the sliding sleeve 86. The inside of the sliding sleeve 86 is a hollow structure. The introduction surface 861 in the sliding sleeve 86 is sleeved on the outer arc surface of the half-body joint 3. The heat dissipation holes and the hollow structure on the outer arc surface of the sliding sleeve 86 can form a convection channel with the outside air, and the hollow structure expands the internal air circulation space. When current passes through the conductive component of the half-body joint 3 to generate heat, the heat will be conducted to the sliding sleeve 86, and the heat will be dissipated more quickly through the heat dissipation holes and the hollow structure, effectively reducing the temperature of the insertion part.

[0031] At the same time, the plug component pushes the sliding sleeve 86 to slide in the insertion sleeve 84. The introduction surface 861 of the sliding sleeve 86 cooperates with the plug component to make the plug insertion smoother. The spring 85 is compressed during the sliding process of the sliding sleeve 86. When the plug component is fully inserted in place, the elastic force of the spring 85 acts on the insertion sleeve 84 through the bearing end 844, so that the outer flange 841 of the insertion sleeve 84 tightly abuts against the positioning support 81, further enhancing the connection stability between the plug and the half-body joint 3. The elastic arms 83 undergo elastic deformation during the plug insertion process and tightly abut against the inner side wall of the electrical interface 2, which not only plays a positioning role but also can effectively buffer the impact force during plug insertion and protect the internal connection components. In addition, a deformation cavity 72 is provided at the contact part between the electrical interface 2 and the plug component. After the plug is inserted in place, the deformation cavity 72 is automatically inflated with gas and expands, filling the gap at the interface, preventing external dust and moisture from entering, and at the same time avoiding electric leakage during the insertion process and ensuring electrical safety.

[0032] As Figure 5 、 Figure 6 and Figure 9As shown, an opening 78 is provided on one side of the outer arc surface of the radial connecting rib 71. The top of the outer arc surface of the radial connecting rib 71 is in contact with the inner arc surface of the arc-shaped abutting surface 51. The bottom of the outer arc surface of the radial connecting rib 71 abuts against a tight tongue 73. A pressing surface 74 is provided on the tight tongue 73 close to the bottom of the outer arc surface of the radial connecting rib 71. One end of the tight tongue 73 away from the pressing surface 74 is provided with a downward pressing end 75. The top of the downward pressing end 75 is connected with an extending elastic surface 76. The lower surface of the downward pressing end 75 is placed on the top of the elastic bow surface 62. Plug-in slots 77 are provided on both the contact member 6 and the outer arc surface of the tight tongue 73. The two plug-in slots 77 are in the same plane.

[0033] When the power storage compartment of the electric vehicle completes power replenishment and it is necessary to separate the photovoltaic energy storage battery vehicle from the power storage compartment, perform the reverse operation. Under the command of the control system, the battery vehicle slowly moves backward, and the plug component is pulled out from the power connection interface 2. As the plug component is pulled out, the elastic bow surface 62 gradually recovers its deformation, the pressure on the tight tongue 73 decreases, and the tight tongue 73 resets under its own elasticity and the action of related components. The clamping force of the locking assembly 7 on the contact member 6 is released. At the same time, the spring 85 returns to its original state, pushing the sliding sleeve 86 to reset. The plug-in sleeve 84 is separated from the plug component, and the elastic arm 83 also returns to its initial state. The sealing structure deflates or contracts, and the entire automatic plugging device returns to its initial state. For axial locking, on the one hand, when the plug component is fully inserted in place, the spring 85 acts on the plug-in sleeve 84 through the bearing end 844, so that the outer flange 841 tightly abuts against the positioning support 81, forming a double locking structure, which ensures the stability of the plug in the axial direction to a certain extent and prevents it from easily coming out axially. On the other hand, the elastic arm 83 undergoes elastic deformation during the plug insertion process and tightly abuts against the inner side wall of the power connection interface 2, which not only plays a positioning role but also can buffer the axial external force impact to a certain extent, further enhancing the axial stability.

[0034] In practical applications, according to different specifications of photovoltaic energy storage battery vehicles and power storage compartments, the dimensions of the docking frame 1, the specifications of the power connection interface 2, and the specific parameters of each component can be adjusted accordingly to ensure the compatibility and applicability of the automatic plugging device.

[0035] Specific operation steps: The vehicle-mounted sensor detects the signal sent by the power connection interface 2 and automatically triggers the plugging program. The plug component on the battery vehicle is pushed by the driving mechanism and translated towards the power connection interface 2. The front end of the plug first contacts the bent section 52 of the conical housing 5. The curved surface of the bent section 52 uses the principle of inclined plane mechanics to decompose the oblique acting force of the plug into a horizontal pushing force and a vertical guiding force, guiding the plug to slide into the power connection interface 2 along the arc-shaped abutting surface 51.

[0036] As the plug is inserted deeper, the outer surface of the plug presses against the contact member 6. The contact member 6 has good elastic deformation ability and moves backward along the arc-shaped abutting surface 51 after being stressed. The elastic bow surface 62 of it deforms. According to the principle of elasticity, the deformation of the elastic bow surface 62 generates an elastic restoring force, which is transmitted to the pressing end 75 of the clamping tongue 73. The clamping tongue 73 is hinged to the radial connecting rib 71 and rotates around the hinge point under the action of the elastic restoring force, so that the pressing surface 74 fits the outer arc surface of the radial connecting rib 71. The structure at the opening 78 elastically deforms, driving the locking assembly 7 to contract, generating a clamping force on the contact member 6, tightly pressing the contact member 6 against the surface of the plug component, realizing close electrical contact and reducing the contact resistance.

[0037] Meanwhile, the insertion of the plug component pushes the sliding sleeve 86 to slide within the socket sleeve 84. The guiding surface 861 of the sliding sleeve 86 cooperates with the plug component to reduce the insertion resistance. The spring 85 is compressed when the sliding sleeve 86 slides to store elastic potential energy. When the plug is fully inserted in place, the spring 85 releases the potential energy and pushes the socket sleeve 84 through the bearing end 844, so that the outer flange 841 abuts against the positioning support 81, forming a double-locking structure and enhancing the connection stability between the plug and the half-body joint 3. In addition, the elastic arm 83 elastically deforms during the insertion process of the plug, abuts against the inner side wall of the electrical interface 2, uses the elastic force to realize the positioning of the plug, and buffers the insertion impact force. When the plug is inserted in place, the sealing rubber ring or sealing airbag at the contact part between the electrical interface 2 and the plug component automatically inflates or expands under the action of the control system to fill the gap and achieve leakage-proof sealing.
