Description

Technical Field

[0001] The present application relates to the technical field of charging equipment, and in particular to a foldable charging equipment. Background Art

[0002] The charging device has a charging bow head. When the vehicle needs to be charged, the charging device controls the charging bow head to move downward and contact the vehicle to charge the vehicle. After charging is completed, the charging bow head usually needs to be retracted to prevent the charging bow head from colliding with passing vehicles. However, if the charging device only adjusts the height of the charging bow head by telescoping up and down, the charging bow head cannot be raised to the maximum extent due to the limited telescopic control length. When a taller vehicle passes, there is still a risk of collision and interference.

[0003] In the related art, there is also a charging device having a motor and a swing frame, one end of the swing frame is connected to the motor, and a charging bow is arranged at the other end of the swing frame. The rotation of the motor can drive the swing frame to rotate, so as to drive the charging bow to move up and down. The swing frame has a folded state and an unfolded state. In the folded state, the swing frame is folded to the plane frame, and the force of the swing frame is transmitted to the motor, so that the motor is still loaded when it is not running. The motor is loaded for a long time, and the loss is large, which affects the service life of the motor.

[0004] In view of this, this application is hereby filed. Summary of the invention

[0048] Embodiment 1

[0049] See also Figures 1 to 5 As shown, the embodiment of the present application provides a foldable charging device, including: a plane frame 1, a translation seat 11 and a swing frame 3, a plane translation mechanism and an auxiliary support mechanism 5 are arranged on the plane frame 1, the translation seat 11 is connected to the plane translation mechanism in a transmission manner, the plane translation mechanism can drive the translation seat 11 to translate along the first direction and / or the second direction on the plane frame 1, the swing frame 3 is connected to the translation seat 11, a charging bow head 4 is connected to the swing frame 3, the swing frame 3 can swing around the translation seat 11, the swing frame 3 has a folded state folded to the plane frame 1 and an unfolded state perpendicular to the plane frame 1, in the folded state, the auxiliary support mechanism 5 is combined with the swing frame 3, and the swing frame 3 is supported on the auxiliary support mechanism 5. Wherein, the first direction and the second direction are perpendicular to each other.

[0050] It should be noted that the applicant has previously applied for patents related to the structure of the plane frame 1, the plane translation mechanism and the translation seat. The specific structures of the plane frame 1, the plane translation mechanism and the translation seat are already prior art. In this application, the specific structures of the plane frame 1, the plane translation mechanism and the translation seat will not be limited. Any mechanical structure that can control the translation seat 11 to move in two-dimensional space, that is, along the X-axis and the Y-axis in a plane can be adopted as the plane translation mechanism of this application.

[0051] See also Figure 2As shown, the swing frame 3 of the foldable charging device provided in the embodiment of the present application can be folded to the plane frame 1 after charging is completed, so as to form a larger passing area at the bottom of the plane frame 1 to avoid passing vehicles. When the swing frame 3 is in the folded state, the swing frame 3 can be supported on the auxiliary support mechanism 5, so that the swing frame 3 is stably in the folded state.

[0052] In some possible implementations, the foldable charging device further includes a driving device, which can drive the swing frame 3 to swing to a folded state or an unfolded state. In the folded state, the auxiliary support mechanism 5 is combined with the swing frame 3, and the swing frame 3 is supported on the auxiliary support mechanism 5, that is, one end of the swing frame 3 where the charging bow 4 is provided is stably supported on the auxiliary support mechanism 5, and the driving device is not required to provide driving force, which reduces consumption, protects the driving device, and prolongs the life of the driving device. The driving device can be a motor 2, and the rotating shaft of the motor 2 is connected to the swing frame 3 to drive the swing frame 3 to swing.

[0053] In some possible implementations, see Figure 3 As shown, the auxiliary support mechanism 5 includes a bracket 51 and a claw assembly arranged on the bracket 51, the bracket 51 is connected to the planar frame 1, and the claw assembly is arranged on the bracket 51. When the swing frame 3 swings to a folded state, the claw assembly and the swing frame 3 are snap-fitted.

[0054] The claw assembly can have a clamping state and a releasing state. When the swing frame 3 swings to the folded state, the clamping assembly will switch to the clamping state under the action of the swing frame 3, and the claw assembly is clamped to the swing frame 3, providing a supporting force at the end of the swing frame 3 away from the motor 2. When the swing frame 3 needs to be switched to the unfolded state (for example, the swing frame 3 needs to be perpendicular to the plane frame 1), the claw assembly can be controlled to switch to the releasing state, and the claw assembly is separated from the swing frame 3, and the motor 2 can drive the swing frame 3 to rotate.

[0055] In some possible implementations, see Figure 3 As shown, the claw assembly includes two claws 52, and a clamping space is formed between the two claws 52. A snap-fitting portion 31 is provided on the swing frame 3. In the folded state, the snap-fitting portion 31 is located in the clamping space, and the two claws 52 are respectively clamped on both sides of the snap-fitting portion 31.

[0056] The two claws 52 are located on both sides of the swing plane of the swing frame 3. In the folded state, the two claws 52 are respectively clamped on both sides of the swing frame 3, so as to stably support the swing frame 3 and prevent the swing frame 3 from tilting.

[0057] In some possible embodiments, the two claws 52 are hinged to the bracket 51 through a hinge 53, and an elastic member 54 is connected between the claws 52 and the bracket 51. During the folding process of the swing frame 3, the snap-fitting portion 31 pushes the bottom ends of the two claws 52, so that the bottom ends of the two claws 52 move away in the opposite direction, and the deformation of the elastic member 54 increases. When the snap-fitting portion 31 swings to the clamping space between the two claws 52, the elastic member 54 restores its deformation and pushes the claws 52 to be snapped into the snap-fitting portion 31.

[0058] When the swing frame 3 swings to the folded state, it will directly act on the two claws 52, so that the two claws 52 are automatically connected to the swing frame 3. During the whole process, there is no need for an electric drive mechanism to control the state of the two claws 52. The overall structure is simple, and no external power is required, and there is no energy consumption.

[0059] In some possible embodiments, a latching protrusion 521 is provided at the bottom end of the claw 52, ​​and the latching protrusions 521 of the two claws 52 extend toward each other, and the latching protrusions 521 have a guiding inclined surface 5211. During the folding process of the swing frame 3, the snap-fitting portion 31 presses against the guiding inclined surfaces 5211 of the latching protrusions 521 of the two claws 52, so that the latching protrusions 521 of the two claws 52 move away in the opposite direction, and the deformation of the elastic member 54 increases. When the snap-fitting portion 31 swings into the clamping space between the two claws 52, the elastic member 54 restores its deformation and pushes the claws 52, so that the latching protrusions 521 of the two claws 52 approach each other, and the snap-fitting portion 31 is supported on the two latching protrusions 521.

[0060] The lower edge of the latching protrusion 521 has a guiding inclined surface 5211 . The guiding inclined surfaces 5211 of the two latching protrusions 521 are arranged in an “eight” shape. In the direction from bottom to top, the distance between the guiding inclined surfaces 5211 of the two latching protrusions 521 gradually decreases. The snap-fitting part 31 of the swing frame 3 can be a plate body, and the width of the snap-fitting part 31 of the swing frame 3 is smaller than the width of the bottom end of the guiding inclined surfaces 5211 of the two locking protrusions 521, and larger than the width of the top end of the guiding inclined surfaces 5211 of the two locking protrusions 521. In the process of the swing frame 3 swinging to the plane frame 1, the snap-fitting part 31 first passes between the bottom ends of the guiding inclined surfaces 5211 of the two locking protrusions 521 and acts on the two guiding inclined surfaces 5211. In the process of the swing frame 3 continuing to swing upward, it can push the two swing frames 3 to swing, so that the distance between the two locking protrusions 521 increases, until the snap-fitting part 31 disengages from the guiding inclined surfaces 5211 of the two locking protrusions 521 and moves to the top of the two locking protrusions 521. At this time, under the action of the elastic member 54, the two claws 52 rotate, so that the locking protrusions 521 of the two claws 52 approach each other, and the snap-fitting part 31 is supported on the upper edges of the two locking protrusions 521.

[0061] In some possible embodiments, the claw 52 is located between the protrusion 521 and the hinge 53 and a connecting hole 522 is provided. The bracket 51 is located between the two claws 52 and a connector 5123 is provided. Two elastic members 54 are connected to the connector 5123, and the two elastic members 54 are respectively connected to the connecting holes 522 on the corresponding claws 52. The elastic member 54 can be a spiral spring with semi-circular ends. One end of the elastic member 54 is hooked on the connecting hole 522, and the other end is hooked on the connector 5123. The connector 5123 can be integrally formed with the bracket 51, or the connector 5123 can be a separate member from the bracket 51, and the two are connected and fixed by fasteners or by welding. The end of the connector 5123 can be provided with an external thread, and a nut is threadedly connected. The end of the elastic member 54 is limited between the nut and the bracket 51, and will not easily break away from the connector 5123.

[0062] In some possible embodiments, the auxiliary support mechanism 5 includes a driving component 55, which is arranged on the bracket 51. The driving component 55 and the claw 52 are in transmission cooperation. When the swing frame 3 is in a folded state, the driving component 55 can drive the claw 52 to rotate, so that the ends of the two claws 52 with the protrusions 521 are separated from each other to release the snap-fitting portion 31.

[0063] After the engaging portion 31 is engaged between the two claws 52, in order to control the engaging portion 31 to be disengaged, it is necessary to drive the two claws 52 to rotate with the help of external force, so that the protrusions 521 of the two claws 52 are separated, so that the engaging portion 31 can be separated from the two claws 52, and the swing frame 3 can be rotated to the unfolded state under the action of the motor 2. The embodiment of the present application is provided with two driving components 55, which are used to extend and abut against the claws 52 when unlocking the swing frame 3, drive the claws 52 to rotate, and make the protrusions 521 of the two claws 52 move away in the opposite direction.

[0064] In some possible implementation schemes, the claw 52 is provided with an outer protrusion 523 at one end of the hinge 53 away from the protrusion 521, and the outer protrusion 523 has an arc end surface. The driving component 55 can be an electric push rod, and the driving component 55 has a telescopic shaft, and the telescopic shaft abuts against the arc end surface. The telescopic shaft telescopic movement can push the arc end surface, so that the protrusions 521 of the two claws 52 move away from each other or move towards each other. The outer protrusion 523 can be understood as a local structure of a disc body. The end of the telescopic shaft of the driving component 55 can be a flat surface, which contacts the arc end surface of the disc body. During the process of telescopic shaft extension, it can act on the arc end surface. During the rotation of the claw 52, ​​the end of the telescopic shaft remains in contact with the arc end surface, which is conducive to the stable transmission of power. During the extension and retraction process, the telescopic shaft will not be separated from the arc end surface, and the driving component 55 can always effectively act on the claw 52.

[0065] In some possible implementations, see Figure 3 As shown, the bracket 51 includes a connecting plate 511, an extension plate 512 and two support plates 513, the connecting plate 511 is parallel to the planar frame 1, and the connecting plate 511 is closely connected to the planar frame 1, the extension plate 512 is vertically connected to the connecting plate 511, the two support plates 513 are both arranged on the extension plate 512, the two support plates 513 are arranged at intervals, and the two support plates 513 are respectively provided with a driving component 55, the two claws 52 are hinged on the extension plate 512, and the two claws 52 are located between the two support plates 513.

[0066] The two support plates 513 are located at the same horizontal height, and a baffle 514 is vertically arranged at one end of the two support plates 513 that are far away from each other. The driving component 55 may include a fixed cylinder and a telescopic shaft connected to the fixed cylinder, and the fixed cylinder may be vertically fixed on the baffle 514. The telescopic direction of the telescopic shaft is parallel to the support plates 513. The two support plates 513 have a limiting effect on the claw 52, ​​so that the claw 52 can only rotate within a certain range, so that the telescopic shaft can maintain an effective effect on the arc end surface on the claw 52, ​​thereby improving the reliability of the device.

[0067] In some possible implementations, see Figure 3 As shown, the extension plate 512 has a short bottom side 5121, a long bottom side 5122 and two side sides, the short bottom side 5121 and the long bottom side 5122 are parallel, the two side sides are arranged on both sides of the short bottom side 5121, and the side sides are respectively connected to the ends of the long bottom side 5122 and the short bottom side 5121, the short bottom side 5121 is connected to the connecting plate 511, and the two ends of the long bottom side 5122 are respectively connected to the two support plates 513. The extension plate 512 is an isosceles trapezoid. Compared with a rectangle, the trapezoid reduces consumables, saves space, and is not easy to interfere with the surrounding side structure. The structural design of the bracket 51 is more reasonable.

[0068] Embodiment 2

[0069] The embodiment of the present application describes in detail the charging bow head 4 at the end of the swing frame of the foldable charging device. The charging bow head 4 includes: a frame 41 and a charging plate 42. The frame 41 is connected to the swing frame, and each of the charging plates 42 is connected to the frame 41 through a pressure sensor 424. The charging device with the charging bow head 4 can charge a vehicle with a pantograph 6. Specifically, the pantograph 6 on the vehicle also includes a frame 41 and a plurality of receiving plates, each of which is connected to the frame 41. The receiving plate has a receiving carbon plate 61, and the area of ​​the large surface of the receiving carbon plate 61 is larger than the bottom contact surface of the charging carbon plate 423 on the charging plate 42. When the vehicle needs to be charged, the charging device can control the charging plate 42 to move downward as a whole until the bottom contact surface of the charging carbon plate 423 contacts the large surface of the top of the receiving carbon plate 61.

[0070] When the charging bow head 4 starts to control the contact with the pantograph of the vehicle, if the pressure value detected by the pressure sensor 424 is less than the preset value, it means that the charging bow head 4 and the pantograph 6 are not in safe and sufficient contact, which may easily cause an arc during the charging process. Therefore, the charging bow head 4 can be controlled to move further toward the vehicle. As the charging bow head 4 moves, the pressure detected by the pressure sensor 424 increases accordingly. When the pressure detected is greater than the preset value, it means that the charging bow and the pantograph 6 are in full contact, and steps such as the charging bow head 4 and the vehicle power-on protocol handshake can be implemented.

[0071] The charging plate 42 includes: an insulator 421 , an adapter 422 , a charging carbon plate 423 , a cable 425 and a pressure sensor 424 . The insulator 421 has a longitudinal threading groove 4213 and an inclined threading groove 4214, wherein the longitudinal threading groove 4213 extends along the central axis of the insulator 421, wherein the inclined threading groove 4214 and the longitudinal threading groove 4213 have an included angle, and the inclined threading groove 4214 is connected to the longitudinal threading groove 4213, and a notch connected to the inclined threading groove 4214 is arranged on the peripheral side wall of the insulator 421, the adapter 422 is a conductor, and the adapter 422 is fixedly connected to the insulator 421, the charging carbon plate 423 is connected to the adapter 422, the cable 425 passes through the notch, the inclined threading groove 4214 and the longitudinal threading groove 4213 in sequence and is connected to the adapter 422, and a pressure sensor is arranged at one end of the insulator 421 away from the adapter 422.

[0072] The present application provides a pressure sensor 424 at the top of the insulator 421, and provides an inclined threading groove 4214 in the insulator 421. The notch of the inclined threading groove 4214 is located on the peripheral side wall of the insulator 421, thereby avoiding the pressure sensor 424 at the top of the insulator 421, and the cable 425 will not interfere with the pressure sensor 424, which facilitates the routing inside the insulator 421. The inner wall of the inclined threading groove 4214 and the inner wall of the longitudinal threading groove 4213 can be smoothly connected, and the transition area between the two does not form a sharp structure, so as to avoid cutting the cable 425.

[0073] In some possible implementations, the insulator 421 has a plurality of umbrella skirts 4212 and a cylindrical platform 4211 located at one end of each umbrella skirt 4212 away from the adapter 422, the circular end surface of the cylindrical platform 4211 away from the top of the umbrella skirt 4212 is connected to the pressure sensor 424, and the notch is provided on the cylindrical circumferential side wall of the cylindrical platform 4211. By providing the notch on the cylindrical wall on the circumferential side of the cylindrical platform 4211 at the top of the insulator 421, the cable 425 can be conveniently extended into the inclined threading groove 4214 through the notch, avoiding interference between the cable 425 and the umbrella skirt 4212.

[0074] In some possible implementations, see Figure 5 As shown, the charging board 42 includes a power terminal 426, and the longitudinal wire threading groove 4213 has a first groove section and a second groove section, the second groove section is located on the side of the first groove section close to the adapter 422, the inner diameter of the second groove section is larger than the first groove section, the power terminal is partially accommodated in the second groove section, and the power terminal is electrically connected to the adapter 422, and the cable 425 is connected to the power terminal.

[0075] The first slot section and the second slot section are connected, and the first slot section and the second slot section are located in the same straight line.
