Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging, and in particular to a mobile new energy charging warehouse with an automatic gun release structure. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. Current new energy vehicles mainly refer to pure electric vehicles. New energy vehicles need to be used with charging equipment, which is usually divided into mobile charging warehouses and fixed charging piles.

[0003] The existing mobile charging warehouse (including a charging warehouse with a fan unit and a battery inside and a charging gun for charging, wherein a locking structure is arranged on the charging gun, and a locking hook arranged thereon can be moved by pressing a push-lock button arranged on the charging gun, and the locking hook can hook a hooking part arranged on the charging socket of the new energy vehicle, thereby making the charging gun and the charging socket stably plugged) is widely used as a temporary charging device. It is generally placed directly at a temporary charging station and fixed by the self-locking mechanism of its casters. There are some problems in its use, such as When charging, the new energy vehicle may slip because the driver does not use the handbrake, or the charging gun is not unplugged after charging is completed and the mobile body is directly started, causing the mobile charging warehouse to be dragged (at this time the charging gun is still plugged into the charging socket of the new energy vehicle). Since the mobile charging warehouse is usually locked by the self-locking mechanism on the bottom casters, it is very easy to cause the charging warehouse to overturn during the towing process of the mobile charging pile, causing the internal battery to collide violently and cause the battery to spontaneously ignite and cause a fire. Therefore, this application provides a mobile new energy charging warehouse with an automatic gun release structure to meet the needs. Summary of the invention

[0042] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0043] Example: Reference Figure 1 A mobile new energy charging warehouse with an automatic gun release structure is shown, including a mobile charging warehouse 1, to which a charging gun 3 is connected via a wire 2, and the charging gun 3 is provided with a press lock button 4 and a movable locking hook 5, and also includes an automatic gun release unit. When the new energy vehicle slips during charging, the lock between the charging gun 3 and the charging socket on the new energy vehicle is automatically released and the charging gun 3 is automatically released from the charging socket.

[0044] As a preferred implementation in this embodiment, Figure 1-3 As shown, the automatic gun removal unit includes a movable ring 9, a fixed ring 10, a first gear rod 14, a second gear rod 15, a transmission gear 16 and a first pull rope 17;

[0045] The movable ring 9 is slidably sleeved on the charging gun 3, and a pressing plate 8 is fixed to the left end of the movable ring 9, and the end of the pressing plate 8 away from the movable ring 9 slides through the limit block 7, and the limit block 7 is fixedly arranged on the outer wall of the charging gun 3;

[0046] The first gear rod 14 and the second gear rod 15 are arranged up and down in the installation groove 13 provided on the outer wall of the charging gun 3. The first gear rod 14 and the second gear rod 15 are both plugged with the transmission gear 16. The transmission gear 16 is rotatably arranged on the inner wall of the installation groove 13. The inner cavity of the installation groove 13 is fixed with an L-shaped limit rod 12. The first gear rod 14 is slidably arranged in the limit cavity surrounded by the L-shaped limit rod 12 and the inner cavity of the installation groove 13. One end of the second gear rod 15 is fixedly connected to the movable ring 9. The movable ring 9 is fixedly connected to the fixed ring 10 through a plurality of connecting springs 11. The fixed ring 10 is fixedly sleeved on the outer wall of the charging gun 3;

[0047] A pressing bevel 6 is provided on one side of the pressing lock button 4 close to the pressing plate 8, and the uppermost end of the pressing bevel 6 is located above the upper end surface of the pressing plate 8, and the lowermost end of the pressing bevel 6 is located below the lower end surface of the pressing plate 8;

[0048] One end of the first pull rope 17 is installed on the mobile charging warehouse 1, and the other end of the first pull rope 17 is fixedly connected to the movable ring 9. The first pull rope 17 is arranged along the path of the wire 2 through the limiting ring 18, and the length of the first pull rope 17 is less than the length of the wire 2.

[0049] When in use, the charging gun 3 is as follows Fig.10As shown, it is plugged and installed with the charging socket of the new energy vehicle. At this time, the locking hook 5 is hooked with the hooking part. When the vehicle slips or the driver does not unplug the charging gun 3 to start and move the vehicle body, as the vehicle body moves, the first pull rope 17 is first pulled into a taut state (at this time, the wire 2 is not straightened, and will not cause pulling on the connection between the wire 2 and the mobile charging warehouse 1). As the vehicle body continues to move, the first pull rope 17 will pull and move the movable ring 9 on the charging gun 3. The movement of the movable ring 9 will drive the second gear rod 15 and the extrusion plate 8 to move away from the new energy vehicle. The connecting spring 11 is pulled by the rope. Through the cooperation of the transmission gear 16, the second gear rod 15 drives the first gear rod 14 to move closer to the new energy vehicle. The extrusion plate 8 contacts and extrudes the extrusion slope 6 on the push-lock button 4, so that one end of the locking hook 5 moves upward to release the hook with the charging socket and keeps the locking hook 5 stationary. After the unlocking state is released, the end of the first gear rod 14 moves out of the mounting groove 13 and forms a conflict with the edge of the charging socket. As the vehicle body moves, the length of the first gear rod 14 extending out of the mounting groove 13 becomes longer and longer, thereby completely pushing the plug-in end of the charging gun 3 out of the charging socket, and finally separating the charging gun 3 from the charging socket. At this time, the charging gun 3 will fall to the ground due to its own gravity. At the same time, the connecting spring 11 drives the extrusion plate 8, the movable ring 9, the first gear rod 14 and the second gear rod 15 to return to their original positions.

[0050] It should be noted that, first, the first pull rope 17 is rotatably set on the outer wall of the mobile charging warehouse 1 through the pin shaft 32, and the direction of the first pull rope 17 can be changed as needed; second, a protective frame 31 is fixed on the outer wall of the charging gun 3 to block the movable ring 9 after the resetting of the movable ring 9 is completed; third, when the mobile charging warehouse 1 is transported by a transport vehicle, the charging warehouse can be fixed by the self-locking mechanism provided on the casters at the bottom of the mobile charging warehouse 1.

[0051] As a preferred implementation manner in this embodiment, a self-locking unit is further included, which automatically locks the first gear rod 14 when the charging gun 3 is just disengaged from the charging socket, so that it cannot move.

[0052] If the first gear rod 14 starts to reset at the moment when the charging gun 3 is just separated from the charging socket, it is likely that the separation process will not be thorough enough, and the charging gun 3 may still maintain a certain contact or hanging state with the charging socket, which is not conducive to the complete separation of the charging gun 3 from the charging socket. Therefore, a self-locking unit is provided to lock the first gear rod 14 after separation, so that the charging gun 3 has enough time to be completely separated from the charging socket, ensuring that a sufficient separation distance is formed between the two. The setting of the self-locking unit enables the charging gun 3 to have a relatively stable separation process when the vehicle is moving. This stability helps to ensure that the charging gun will not re-contact the charging socket due to the movement of the vehicle.

[0053] As a preferred implementation in this embodiment, Figure 4-6 As shown, the self-locking unit includes a fixed self-locking block 19, a movable self-locking block 20 and a self-locking spring 29;

[0054] The fixed self-locking block 19 is fixedly arranged at the lower end of the first gear rod 14, and the inner cavity of the charging gun 3 is provided with a rectangular sliding cavity adapted to the fixed self-locking block 19, and the two side ends of the fixed self-locking block 19 are respectively provided with a long inclined surface 191 and a short inclined surface 192;

[0055] The movable self-locking block 20 is slidably disposed in the inner cavity of the charging gun 3 and is fixedly connected to the charging gun 3 via a self-locking spring 29 . A contact inclined surface 202 and a plane 201 are disposed on the movable self-locking block 20 . The contact inclined surface 202 is disposed opposite to the long inclined surface 191 .

[0056] When the first gear rod 14 just pushes the plug-in end of the charging gun 3 out of the charging socket, the upper end of the movable self-locking block 20 is squeezed and collides with the short inclined surface 192 through the elastic force of the self-locking spring 29 (when the plug-in end of the charging gun 3 is not completely pushed out of the charging socket, the contact inclined surface 202 on the movable self-locking block 20 will contact the long inclined surface 191 on the moving fixed self-locking block 19, and the movable self-locking block 20 is squeezed and compresses the self-locking spring 29. As the fixed self-locking block 19 continues to move, the movable self-locking block 20 will eventually pass over the fixed self-locking block 19 to block its reset), and through the elastic force of the self-locking spring 29, the first gear rod 14 continues to extend out of the mounting groove 13 for a distance, and finally the plane 201 of the movable self-locking block 20 contacts the side plane (located on the side of the short inclined surface 192) of the fixed self-locking block 19, thereby blocking the reset movement of the first gear rod 14, which is conducive to the subsequent complete separation of the charging gun 3 from the charging socket.

[0057] It should be noted that, first, the contact slope 202 on the movable self-locking block 20 is adapted to the long slope 191 and is larger than the short slope 192. The outer surfaces of the fixed self-locking block 19 and the movable self-locking block 20 are both set to smooth surfaces to reduce the friction resistance. Second, the upper end of the movable self-locking block 20 is located in the rectangular sliding cavity, such as Figure 6 shown.

[0058] As a preferred implementation manner in this embodiment, an automatic unlocking unit is further included, which is used to automatically unlock the first gear rod 14 .

[0059] After the charging gun 3 is completely separated from the charging socket, the lock of the first gear rod 14 is released by the automatic unlocking unit, that is, the blocking of the first gear rod 14 by the movable self-locking block 20 is released, so that the first gear rod 14 can be restored to its original position by the elastic force of the connecting spring 11, and there is no need for subsequent manual resetting operation of the first gear rod 14.

[0060] As a preferred implementation in this embodiment, Figure 4-9 As shown, the automatic unlocking unit includes a second pull rope 21, a plurality of guide wheel groups 22, a weight block 24, and a support plate 26 fixed on the outer wall of the mobile charging warehouse 1;

[0061] The support plate 26 is slidably penetrated by the column 28, and a resisting plate 27 is fixedly installed at the lower end of the column 28, and the lower end of the resisting plate 27 is fixedly connected to the lower end of the support plate 26 through a return spring 30;

[0062] The conductor 2 is arranged along a U-shaped path through the matching parts of a plurality of guide wheel sets 22;

[0063] One end of the second pull rope 21 is connected to the upper end of the column 28, and the second pull rope 21 is arranged along the path of the wire 2 through a plurality of limit rings 18, and the other end of the second pull rope 21 passes through the movable ring 9 and the outer wall of the charging gun 3 and is connected to the movable self-locking block 20;

[0064] The weight-adding block 24 is slidably sleeved with the U-shaped part of the conductor 2 through the slip ring 23, and the lower end of the weight-adding block 24 contacts the upper end surface of the support plate 26. The lower end of the weight-adding block 24 is fixed with a movable rod 25 that slides through the support plate 26, and the lower end of the movable rod 25 contacts the contact plate 27.

[0065] In the initial state, the return spring 30 is in a stretched state, and the self-locking spring 29 is in a compressed state.

[0066] When the vehicle slips and the first pull rope 17 is not straightened, the weight block 24 moves upward under the pull of the wire 2. At this time, the contact plate 27 moves upward under the action of the reset spring 30, and the self-locking spring 29 drives the movable self-locking block 20 to move upward until the self-locking spring 29 is in a naturally extended state (at this time, the lower end of the movable rod 25 does not contact the contact plate 27). After the self-locking spring 29 is in a naturally extended state, the first pull rope 17 is straightened. As the weight block 24 continues to rise, the moving fixed self-locking block 19 will come into contact with the movable self-locking block 20, and finally the movable self-locking block 20 is The movable self-locking block 20 forms an obstruction to the fixed self-locking block 19, thereby hindering the resetting of the first gear rod 14. At this time, the charging gun 3 is separated from the charging socket. At this time, due to the certain distance between the weight-added block 24 and the contact plate 27 below, the weight-added block 24 needs to move for a period of time under the action of its own gravity before it can drive the movable self-locking block 20 to move downward through the second pull rope 21, thereby releasing the limit on the fixed self-locking block 19. At this time, the first gear rod 14 starts to perform the resetting movement, which provides an interval time for the resetting of the first gear rod 14, which is conducive to the complete separation of the charging gun 3 from the charging socket.

[0067] It should be noted that, first, when the weight-increasing block 24 moves upward, its weight will act on the wire 2, and the wire 2 can bear this weight without causing a large pulling effect on the connection between the wire 2 and the mobile charging warehouse 1; second, the setting of the weight-increasing block 24 can increase the overall weight of the mobile charging warehouse 1, thereby making it more stable when fixed.

[0068] As a preferred implementation in this embodiment, a retarding unit is further included to reduce the descending speed of the weight block 24, so as to reduce the collision strength between the weight block 24 and the support plate 26 and reduce the dragging friction when the charging gun 3 contacts the ground.

[0069] It is used to slow down the descending speed of the weight-added block 24, which is beneficial to reduce the collision between the weight-added block 24 and the support plate 26 and improve the service life of the components; the setting of the slowing unit can reduce the dragging speed of the wire 2, thereby avoiding the formation of more intense dragging friction between the charging gun and the ground, and reducing damage to the charging gun.

[0070] It should be noted that the provision of the slow-down unit also prolongs the interval time for the first gear rod 14 to reset, which can avoid the possibility of the charging gun 3 being connected to the charging socket for the second time due to the interval time being too short.

[0071] As a preferred implementation in this embodiment, Fig.10 As shown, the buffer unit includes a plurality of extrusion wheels 33 rotatably arranged on the periphery of the movable rod 25 and an elastic sleeve 38 fixedly sleeved on the periphery of the movable rod 25. The plurality of extrusion wheels 33 are all arranged in the installation cavity of the support plate 26. The outer walls of the plurality of extrusion wheels 33 are provided with a plurality of extrusion protrusions 37 in an arc shape. The outer walls of the plurality of extrusion wheels 33 are in contact with the outer wall of the elastic sleeve 38. The outer walls of the extrusion wheels 33 are provided with a first baffle 34 and a second baffle 35. The first baffle 34 and the second baffle 35 are respectively located on the upper and lower sides of the baffle plate 36. The baffle plate 36 is fixedly arranged on the inner wall of the installation cavity.

[0072] At the beginning, if Fig.10 As shown, the second stop bar 35 is in contact with the baffle plate 36. When the movable rod 25 moves upward, the friction between the elastic sleeve 38 and the extrusion protrusion 37 causes the extrusion wheel 33 to rotate counterclockwise. When the elastic sleeve 38 is in contact and separated from the extrusion protrusion 37, the elastic sleeve 38 is in contact with the arc-shaped outer wall of the extrusion wheel 33 (this extrusion force is small, which can reduce the resistance to the rise of the weight-increasing block 24) and drives the extrusion wheel 33 to continue to rotate counterclockwise. When the first stop bar 34 contacts the baffle plate 36, the extrusion wheel 33 stops rotating, and the movable rod 25 continues to move upward. At this time, the resistance to the movable rod 25 is the smallest. When the movable rod 25 moves downward, its extrusion wheel 33 rotates clockwise, and finally forms the following Fig.10In the state shown, the second baffle 35 contacts the baffle plate 36 to form a blockage, the extrusion wheel 33 cannot continue to rotate clockwise, and the movable rod 25 continues to move downward. At this time, the movable rod 25 is subjected to the greatest resistance (and the resistance is less than the gravity of the weight-added block 24 itself), thereby reducing the descending speed of the weight-added block 24.

[0073] It should be noted that, first, the extrusion protrusion 37 is set to a semicircular structure; second, the movable rod 25 can be set to a square structure, which can make the weight-increasing block 24 perform stable linear motion.

[0074] As a preferred implementation in this embodiment, the protrusion amplitude of the extrusion protrusion 37 gradually increases from bottom to top.

[0075] The purpose is to make the resistance it encounters smaller and smaller until it is constant (minimum constant) when the movable rod 25 moves upward. The smaller the resistance, the smaller the pulling force on the wire 2 from the weight block 24, which is beneficial to the stability of the connection between the wire 2 and the mobile charging warehouse 1. When the movable rod 25 moves downward, the resistance it encounters becomes larger and larger until it is constant (maximum constant). The greater the resistance, the better the effect of reducing the falling speed of the weight block 24, thereby enhancing the retarding effect of the weight block 24.

[0076] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
