[0002] In recent years, with rapid economic development and increasing public awareness of environmental protection, many cities are facing the challenge of upgrading their fuel-powered buses to green new energy buses. Consequently, a charging device for electric buses has emerged. Currently, the replacement of fuel-powered buses with electric buses primarily uses traditional car charging guns. However, with the application of high-power charging, a new type of roof-mounted charging device has been invented and widely adopted.

[0003] In existing technology, to charge an electric vehicle, a pantograph can be installed on the electric vehicle, and a charging pantograph that works in conjunction with the pantograph can be installed on a roof-mounted charging device. When charging an electric vehicle, the copper busbars in the pantograph of the electric vehicle need to come into contact with the copper busbars in the charging pantograph, so that the electric vehicle's power battery can receive electrical energy from the charging pantograph, thereby performing the charging operation.

[0004] However, due to the influence of construction technology, the road surface may be uneven, which makes it easy for the copper electrode busbars of the existing charging pantograph to have poor contact when charging electric vehicles. Summary of the Invention

[0019] The first sliding member is hinged to the first connecting part, the second sliding member is hinged to the support beam, and the two ends of the elastic member abut against the first sliding member and the second sliding member respectively. Under the action of the elastic member, the first sliding member has a tendency to move away from the second sliding member so that the charging electrode can abut against the power receiving device of the vehicle.

[0020] In a preferred embodiment of the present invention, the length directions of the first slider and the second slider are set at an angle to the vertical direction.

[0021] In a preferred embodiment of the present invention, the suspension tie rod includes a tension spring, a tension sleeve, a first telescopic rod, and a second telescopic rod;

Detailed Implementation

[0036] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 and Figure 2 As shown, this embodiment provides a charging pantograph and a charging suspension. The charging pantograph specifically includes a housing (not shown in the figure), a charging suspension device, and a drive device 500. The drive device 500 is tractively connected to the charging suspension device. When the vehicle to be charged reaches a preset charging position, the drive device 500 can drive the charging suspension device to the corresponding position according to the specifications of the vehicle. Specifically, as shown... Figures 3-6 As shown, the charging suspension device provided in this embodiment includes: a suspension body 100, a telescopic device 200, a charging electrode 300, and a suspension tie rod 400. The charging electrode 300 has a lap electrode 301 for contacting the vehicle's power receiving device, and the charging electrode 300 includes a first connecting portion 303 and a second connecting portion 304 spaced apart. The first connecting portion 303 is connected to the suspension body 100 through the telescopic device 200, so that the lap electrode 301 can approach or move away from the suspension body 100. The two ends of the suspension tie rod 400 are respectively hinged to the second connecting portion 304 and the suspension body 100. The length direction of the suspension tie rod 400 is set at an angle to the telescopic direction of the telescopic device 200. The suspension tie rod 400 and the telescopic device 200 are configured to cooperate in constraining the movement of the charging electrode 300, so that the lap electrode 301 can reliably connect with the vehicle's power receiving device. Specifically, in this embodiment, the drive device 500 is a scissor telescopic mechanism, and other mechanisms may also be belt drive mechanisms, etc. Of course, in one embodiment, the charging bow may not need to be equipped with a separate driving device 500, and the embodiments of the present invention do not impose specific limitations.

[0038] The charging suspension device provided in this embodiment can connect with the receiving device. When the vehicle to be charged moves to the position corresponding to the charging suspension body 100, the charging pantograph drive device 500 drives the suspension body 100 to move vertically downward until the connecting electrode 301 is in complete contact with the vehicle's receiving device. At this time, the connecting electrode 301 charges the vehicle. The suspension body 100 serves as the mounting body for the charging electrode 300, the telescopic device 200, and the suspension tie rod 400. That is, the charging electrode 300 is located on the side of the suspension body 100 closest to the ground. When the charging electrode 300 contacts the vehicle's receiving device, if the vehicle is tilted due to the road surface, the charging electrode 300 will contact the receiving device at a certain angle. At this time, the charging electrode 300 can be adjusted vertically through the telescopic device 200. At the same time, the telescopic device 200 and the suspension tie rod 400 can adjust the connection angle of the charging electrode 300, thereby ensuring that the charging electrode 300 can be tightly connected with the receiving device during the charging process, so that the vehicle can be charged smoothly.

[0039] It should be noted that, as Figure 3 As shown, when the vehicle is charging, the drive unit 500 drives the suspension body 100 to move downward and connect with the power receiving device on the vehicle roof. At the same time, a downward force Fr is generated and a reaction force Fs is received from the power receiving device on the vehicle roof. The force Fr acts on the hinge point between the charging electrode 300 and the telescopic device 200 through the compression telescopic device 200 as the rotation point, generating Fa. This force is decomposed into a horizontal force Fx and a vertical force Fy. The vertical force Fy acts on the charging electrode 300 and cancels out the reaction force Fs, while making the charging electrode 300 firmly pressed. The horizontal force Fx generated balances the tension generated by the suspension tie rod 400. Simultaneously, during the process of achieving force balance through compression, the suspension tie rod 400 rotates around the hinge point between the charging electrode 300 and the suspension tie rod 400 as a rotation point to maintain the force balance of the charging electrode 300. At the same time, the charging electrode 300 can be finely adjusted in angle around the hinge point between the charging electrode 300 and the telescopic device 200 as a rotation point according to the unevenness of the vehicle roof, thereby adapting to the unevenness of the vehicle roof caused by uneven ground. The charging electrode 300 and the receiving device make firm and reliable contact.

[0040] Optionally, the bridging electrode 301 can be a bridging copper busbar. Similarly, the vehicle's power receiving device can be a pantograph copper busbar. By utilizing the contact abutment of the copper busbars, the electrical signal connection is ensured, thereby enabling the vehicle to be charged.

[0041] This embodiment provides a charging suspension device, including: a suspension body 100, a telescopic device 200, a charging electrode 300, and a suspension tie rod 400; the charging electrode 300 has a lap electrode 301 for contacting a power receiving device of the vehicle, and the charging electrode 300 includes a first connecting portion 303 and a second connecting portion 304 spaced apart, the first connecting portion 303 being connected to the suspension body 100 via the telescopic device 200; both ends of the suspension tie rod 400 are hinged to the second connecting portion 304 and the suspension body 100, respectively. When the electrode of the power receiving device tilts due to uneven ground conditions, the charging electrode 300 is connected to the telescopic device 200 and the suspension tie rod 400 simultaneously. With zero hinge, the suspension tie rod 400 and the telescopic device 200 are configured to coordinately constrain the movement of the charging electrode 300. This allows the telescopic device 200 to reciprocate while the connecting electrode 301 moves back and forth, while the suspension tie rod 400 can rotate the charging electrode 300 relative to the suspension body 100. This enables the charging electrode 300 to rotate according to the tilt angle of the receiving device, improving the adaptive ability of the charging suspension device to uneven ground. This ensures stable connection between the copper busbar of the connecting electrode 301 and the copper busbar of the receiving device, alleviating the technical problem in the prior art where uneven ground can easily cause poor connection of the electrode copper busbar when the pantograph is charging an electric vehicle.

[0042] Based on the above embodiments, in a preferred embodiment of the present invention, the charging electrode 300 further includes a fixed base 302; the extension direction of the fixed base 302 and the extension direction of the lap electrode 301 are both perpendicular to the extension direction of the vehicle's power receiving device, and the lap electrode 301 is installed on the side of the fixed base 302 away from the telescopic device 200; in this embodiment, the fixed base 302 is used to ensure the extension length of the lap electrode 301, which improves the adaptability of the charging electrode to different vehicle parking accuracies and further improves the reliable docking of the charging electrode and the lap electrode.

[0043] The fixed base 302 has a receiving groove, and the extension direction of the fixed base 302 is arranged perpendicular to the extension direction of the vehicle's power receiving device. The lap electrode 301 extends along one side of the fixed base 302 and is installed in the receiving groove.

[0044] In a preferred embodiment of the present invention, the fixed base 302 includes a first sidewall 312 and a second sidewall 322 that are adjacent to each other and arranged at an angle. There are two first sidewalls 312, and the two first sidewalls 312 are respectively connected to the two sides of the second sidewall 322 to form a receiving groove for installing the overlapping electrode 301. The first connecting part 303 is connected to the second sidewall 322, and the telescopic device 200 is hinged to the first connecting part 303. Along the direction of movement perpendicular to the overlapping electrode 301, the force of the telescopic device 200 acting on the first sidewall 312 and the force of the suspension rod 400 acting on the second sidewall 322 are matched in magnitude and opposite in direction.

[0045] The second connecting part 304 is connected to the first side wall 312, and the suspension rod 400 is hinged to the fixed base 302 through the second connecting part 304. The telescopic device 200 and the suspension rod 400 are used together to keep the overlapping electrode 301 in force balance along the direction perpendicular to the movement direction through the fixed base 302.

[0046] In this embodiment, the fixed base 302 can be a fixed plate. By providing a receiving groove on one side of the fixed plate, the overlapping electrode 301 can be evenly arranged along the extension direction of the receiving groove, and the overlapping electrode 301 is connected to the fixed base 302. Optionally, the overlapping electrode 301 can be floatingly installed in the receiving groove.

[0047] The fixed base 302 may include two first side plates and one second side plate. The first and second side plates may be arranged perpendicularly or at an angle. The second side plate may have an electrode hole, which allows the charging cable of the charging pantograph to be electrically connected to the lap electrode 301 inside the receiving groove. The telescopic device 200 is hinged to the surface of the second side plate away from the receiving groove. The suspension rod 400 is connected to the outer wall of the first side plate of the receiving groove of the fixed base 302. That is, the telescopic device 200 can apply a force to the vertical rotation direction of the lap electrode 301, and at the same time, the suspension rod 400 can apply a force to the rotation direction of the fixed base 302.

[0048] In a preferred embodiment of the present invention, multiple telescopic devices 200 are provided, and the multiple telescopic devices 200 are arranged at intervals along the extension direction of the fixed base 302. The two ends of each telescopic device 200 are respectively hinged to the fixed base 302 and the suspension body 100. The number of suspension rods 400 corresponds one-to-one with the number of telescopic devices 200. Each suspension rod 400 is hinged to the fixed base 302 at the position corresponding to the telescopic device 200. Each group of telescopic devices 200 and the corresponding suspension rod 400 act together on the first side wall 312 and the second side wall 322 of the fixed base 302.

[0049] Optionally, there can be two telescopic devices 200, which are located at both ends of the fixed base 302 respectively, and can be connected to the fixed base 302 respectively. At the same time, the telescopic devices 200 and the suspension rods 400 are arranged in a one-to-one correspondence, that is, each telescopic device 200 and the corresponding suspension rod 400 apply a force to one end of the fixed base 302, thereby ensuring that the lap electrode 301 is in complete contact with the power receiving device through the fixed base 302.

[0050] In a preferred embodiment of the present invention, the suspension body 100 includes a support beam 101 and a bracket 102 connected at an angle; the support beam 101 and the bracket 102 are fixedly connected, the extension direction of the support beam 101 is the same as the extension direction of the fixed base 302, the two ends of the telescopic device 200 are respectively hinged to the fixed base 302 and the support beam 101, and the suspension tie rod 400 is hinged to the end of the bracket 102 away from the support beam 101.

[0051] In a preferred embodiment of the present invention, the suspension body 100, suspension tie rod 400, charging electrode 300 and telescopic device 200 are connected in sequence, and the projection of the four components along the extension direction of the fixed base 302 forms a planar four-bar linkage.

[0052] In this embodiment, when the telescopic device extends or retracts, the charging electrode 300 can adjust its position through the suspension tie rod 400 and the telescopic device 200, which helps to ensure the stability of the suspension body, the suspension tie rod and the charging electrode, thereby improving the motion stability of the charging suspension.

[0053] In a preferred embodiment of the present invention, two sets of charging electrodes 300 are provided, and the two sets of charging electrodes 300 are respectively located on both sides of the suspension body 100. The two sets of charging electrodes 300 are arranged symmetrically, and each set of charging electrodes 300 is connected to the suspension body 100 through the telescopic device 200 and the suspension tie rod 400.

[0054] Optionally, the support 102 is trapezoidal in shape. Two support beams 101 can be provided, each connected to one side of the larger base of the trapezoidal support. That is, the support 102 can include support beams, first connecting beams, and second connecting beams. Four second connecting beams are provided, each located at one end of one of the two support beams 101 and connected to the support beams 101. Two first connecting beams are provided, each parallel to the support beams 101, meaning the first connecting beam connects to the end of the second connecting beam furthest from the support beam 101. Adjacent second connecting beams are connected by support beams. Thus, the two support beams and the two first connecting beams form a support 102 with a smaller area. The bottom surface utilizes a trapezoidal bracket, with both ends of the telescopic device 200 hinged to the fixed base 302 and the support beam 101 respectively. Each suspension rod 400 is hinged to the end of the support beam away from the support beam 101. The telescopic device 200 and the fixed base 302 have an angle, and the suspension rod 400 and the fixed base 302 also have an angle. Thus, by compressing the telescopic device 200, the hinge point between the charging electrode 300 and the telescopic device 200 can be used as a rotation point, making the charging electrode 300 firmly pressed. At the same time, during the process of compressing to achieve force balance, the suspension rod 400 rotates around the hinge point between the charging electrode 300 and the suspension rod 400 as a rotation point to maintain the force balance of the charging electrode 300.

[0055] In a preferred embodiment of the present invention, the telescopic device 200 includes a telescopic body 201 and an elastic element 202; the two ends of the telescopic body 201 are respectively connected to the first connecting part 303 and the support beam 101, and the elastic element 202 is located between the first connecting part 303 and the support beam 101, and the elastic element 202 is used to reset the telescopic body 201.

[0056] In this embodiment, the first connecting part 303 can be a first hinge seat. The first hinge seat is fixedly connected to the surface of the second side plate, and the first hinge seat has a rotating groove. One end of the telescopic body 201 extends into the rotating groove. The telescopic body 201 can pass through the two side walls of the rotating groove through the hinge shaft to ensure the hinged rotation of the telescopic body 201 and the first hinge seat.

[0057] Similarly, it may also include a second hinge seat, which is fixedly connected to the surface of the support beam 101, and the second hinge seat is provided with a rotating groove. The other end of the telescopic body 201 extends into the rotating groove. The telescopic body 201 can pass through the two side walls of the rotating groove through the hinge shaft to ensure the hinged rotation of the telescopic body 201 and the second hinge seat.

[0058] In a preferred embodiment of the present invention, the telescopic body 201 includes a first sliding member 211 and a second sliding member 221 that are slidably connected; the first sliding member 211 is hinged to the first connecting portion 303, the second sliding member 221 is hinged to the support beam 101, and the two ends of the elastic member 202 abut against the first sliding member 211 and the second sliding member 221 respectively. Under the action of the elastic member 202, the first sliding member 211 has a tendency to move away from the second sliding member 221, so that the charging electrode 300 can abut against the power receiving device of the vehicle.

[0059] In a preferred embodiment of the present invention, the length directions of the first slider 211 and the second slider 221 are set at an angle to the vertical direction.

[0060] In this embodiment, the first sliding member 211 can be a connecting sleeve, and the second sliding member 221 can be a telescopic rod. One end of the telescopic rod is hinged to the second hinge seat, and the other end of the telescopic rod is inserted into the connecting sleeve. The end of the connecting sleeve away from the telescopic rod is hinged to the first hinge seat. The telescopic rod and the connecting sleeve are slidably connected. The elastic member 202 can be a compression spring. The compression spring is sleeved on the outside of the connecting sleeve and the telescopic rod, and both ends of the compression spring abut against the telescopic rod and the connecting sleeve, respectively. The compression spring has an elastic tendency to move the connecting sleeve away from the telescopic rod, so that the charging electrode 300 abuts against the vehicle's power receiving device.

[0061] Alternatively, the elastic element 202 can also be a gas spring. In this embodiment, a first annular protrusion is provided at one end of the connecting sleeve near the first hinge seat, and a second annular protrusion is provided at one end of the telescopic rod near the second hinge seat. When the telescopic rod extends into the connecting sleeve, the two ends of the compression spring abut against the first annular protrusion and the second annular protrusion, respectively. Furthermore, when the telescopic rod extends into the connecting sleeve, a limit slot can be arranged at the opening position of the connecting sleeve away from the first hinge seat, that is, the connecting sleeve can ensure that the telescopic rod will not separate from the connecting sleeve. When the lap electrode 301 contacts the vehicle's power receiving device, the lap electrode 301 applies a force to the connecting sleeve through the fixed base 302. The connecting sleeve can apply a force to the compression spring. By overcoming the force of the compression spring through the connecting sleeve, the connecting sleeve and the telescopic rod move relative to each other. At the same time, the connecting sleeve can rotate around the second hinge seat, and the telescopic rod can rotate around the first hinge seat. Thus, while the lap electrode 301 is fully in contact with the power receiving device, the force balance is ensured, and the charging electrode 300 is firmly pressed together.

[0062] In a preferred embodiment of the present invention, the suspension tie rod 400 includes a tension spring, a tension sleeve 401, a first telescopic rod 402, and a second telescopic rod 403. The first telescopic rod 402 and the second telescopic rod 403 are respectively inserted into the two ends of the tension sleeve 401, and the first telescopic rod 402 and the second telescopic rod 403 can reciprocate relative to the tension sleeve 401. The first telescopic rod 402 is hinged to the first connecting part 303, and the second telescopic rod 403 is hinged to the bracket 102. The tension spring is located inside the tension sleeve 401, and the two ends of the tension spring are respectively connected to the first telescopic rod 402 and the second telescopic rod 403. The tension spring has an elastic tendency to bring the first telescopic rod 402 and the second telescopic rod 403 closer to each other, so as to limit the rotation of the charging electrode 300 relative to the suspension body 100.

[0063] In this embodiment, the second connecting part 304 can be a third hinge seat. The third hinge seat is fixedly connected to the surface of the first side plate, and the third hinge seat has a rotating groove. One end of the suspension rod 400 extends into the rotating groove. The suspension rod 400 can pass through the two side walls of the rotating groove through the hinge shaft to ensure the hinged rotation of the suspension rod 400 and the third hinge seat.

[0064] Similarly, it may also include a fourth hinge seat, which is fixedly connected to the surface of the bracket 102, and the fourth hinge seat has a rotation groove. The other end of the suspension rod 400 extends into the rotation groove. The suspension rod 400 can pass through the two side walls of the rotation groove through the hinge shaft to ensure the hinged rotation between the suspension rod 400 and the fourth hinge seat.

[0065] In this embodiment, when the first telescopic rod 402 and the second telescopic rod 403 are respectively inserted into the tension sleeve 401, the two ends of the tension spring are connected to the first telescopic rod 402 and the second telescopic rod 403 respectively. The first telescopic rod 402 and the second telescopic rod 403 are respectively inserted into the tension sleeve 401. Limiting grooves can be arranged at the two open ends of the tension sleeve 401, that is, the tension sleeve 401 can ensure that the first telescopic rod 402 and the second telescopic rod 403 will not separate from the tension sleeve 401. When the lap electrode 301 contacts the vehicle's power receiving device, the lap electrode 301 applies a force to the first telescopic rod 402 through the fixed base 302. The first telescopic rod 402 can then apply a force to the tension spring. By overcoming the force of the tension spring through the first telescopic rod 402, the first telescopic rod 402 and the second telescopic rod 403 move relative to the tension sleeve 401. At the same time, the first telescopic rod 402 can rotate around the third hinge seat, and the second telescopic rod 403 can rotate around the fourth hinge seat. This ensures that the force balance is maintained while the lap electrode 301 is in complete contact with the receiving device, so that the charging electrode 300 is firmly pressed together. In addition, the charging electrode 300 can be finely adjusted in angle around the hinge point between the charging electrode 300 and the first telescopic rod 402 as the rotation point according to the unevenness of the vehicle roof, so as to adapt to the unevenness of the vehicle roof and ensure that the charging electrode 300 and the receiving device are firmly and reliably connected.

[0066] Optionally, the suspension tie rod 400 may also employ a threaded telescopic sleeve, a first telescopic rod 402, and a second telescopic rod 403, thereby achieving adjustable length of the suspension tie rod 400 by manually adjusting the length of the thread.
