Description

Technical Field

[0001] This utility model relates to the field of new energy electrified heavy truck technology, specifically to a pantograph for new energy electrified heavy trucks. Background Technology

[0002] New energy electrified heavy-duty trucks generally obtain power from overhead contact lines or electric rails to achieve long-distance, heavy-load transportation. Existing pantographs have the following drawbacks:

[0003] The lifting and translation mechanism has high rigidity and cannot compensate for the displacement caused by vehicle bumps and uneven tracks in real time. This results in large fluctuations in the contact pressure between the bow head and the contact wire, which can easily lead to arcing and burning.

[0004] A single spring has a limited travel, which can easily cause momentary disconnection from the grid on sharp turns or bumpy roads, affecting the continuity of power supply.

[0005] Based on the above, this utility model proposes a pantograph for new energy electrified heavy trucks, which can effectively solve the above problems. Utility Model Content

[0029] Example 1:

[0030] like Figures 1 to 5 As shown, this utility model provides a pantograph for new energy electrified heavy trucks, including:

[0031] The pantograph body 210, lifting device, and translation device are included. The pantograph body 210 includes a support plate 211, a connecting arm 212, a first lead screw mechanism 213, and a pantograph head 214. One end of the connecting arm 212 is rotatably connected to the side of the support plate 211, and the other end is provided with the pantograph head 214. A third connecting column 215 is fixedly provided on the top of the support plate 211. One end of the first lead screw mechanism 213 is rotatably connected to the third connecting column 215, and the other end is rotatably connected to the side of the connecting arm 212. The lifting device is used to control the pantograph body 210 to move up and down, and the translation device is used to control the lifting device to move left and right.

[0032] The lifting device is mounted on the translation device, and the support plate 211 of the pantograph body 210 is connected to the lifting device.

[0033] Through the coordinated operation of the lifting device and the pantograph body 210, the pantograph can move up and down according to the vehicle's driving status, and move left and right through the translation device, adapting to various working conditions during vehicle operation. The lifting device and translation device form a three-level linkage system of "lifting-translation-pantograph head", realizing three-dimensional adaptive compensation, solving the problem of rigid impact on the charging line, and preventing disconnection during charging.

[0034] Example 2:

[0035] like Figures 1 to 5 As shown, this utility model provides a pantograph for new energy electrified heavy trucks, including:

[0036] The pantograph body 210, lifting device, and translation device are included. The pantograph body 210 includes a support plate 211, a connecting arm 212, a first lead screw mechanism 213, and a pantograph head 214. One end of the connecting arm 212 is rotatably connected to the side of the support plate 211, and the other end is provided with the pantograph head 214. A third connecting column 215 is fixedly provided on the top of the support plate 211. One end of the first lead screw mechanism 213 is rotatably connected to the third connecting column 215, and the other end is rotatably connected to the side of the connecting arm 212. The lifting device is used to control the pantograph body 210 to move up and down, and the translation device is used to control the lifting device to move left and right.

[0037] The lifting device is mounted on the translation device, and the support plate 211 of the pantograph body 210 is connected to the lifting device.

[0038] The pantograph head 214 includes a base plate 2141, a carbon sliding plate 2142, a guide rod 2143, and a first spring 2144. The guide rod 2143 is fixedly provided at the bottom of the carbon sliding plate 2142. The guide rod 2143 passes through the base plate 2141 and is fixedly connected to the first limiting block 2145. The first spring 2144 is sleeved on the guide rod 2143 located between the base plate 2141 and the carbon sliding plate 2142.

[0039] When the carbon slide plate 2142 is subjected to pressure, it can transmit the pressure to the first spring 2144. The first spring 2144 can provide a buffer function to absorb longitudinal impact and avoid damage from hard contact. The guide rod 2143 prevents deviation and ensures the straightness of the carbon slide plate 2142.

[0040] Furthermore, in another embodiment, the carbon slide plate 2142 is provided with inclined surfaces 2146 on both sides.

[0041] The purpose of setting the slope 2146 is to facilitate entry into the power supply line 110 and improve the smoothness.

[0042] Further, in another embodiment, the translation device includes a base 231, a first guide rail 232, a second guide rail 233, a third support frame 234, a motor 235, a gear 236, and a rack 237. The base 231 has a vertical plate 238, and the first guide rail 232 is also provided on the base 231. The second guide rail 233 is provided on the side of the vertical plate 238. A first slider is slidably connected to the first guide rail 232, and a second slider is slidably connected to the second guide rail 233. The third support frame 234 is fixedly mounted on the first slider, and the second slider is fixedly connected to the side of the third support frame 234. A mounting plate 239 is fixedly mounted on the side of the support plate 211, and a motor 235 is fixedly mounted on the mounting plate 239. A gear 236 is connected to the motor shaft of the motor 235, and a rack 237 is fixedly mounted on the vertical plate 238 corresponding to the gear 236. The gear 236 meshes with the rack 237.

[0043] Motor 235 drives gear 236 to rotate. Gear 236, in cooperation with rack 237, generates a driving force for left and right movement. Guided by the guide rail, the lifting device can move left and right.

[0044] The sliding connection of the double guide rails enables the left and right movement of the lifting device, ensuring that the pantograph can be adjusted in real time according to the movement of the vehicle.

[0045] Furthermore, in another embodiment, the lifting device includes a second lead screw mechanism 221, a third guide rail 222, and a second spring 223. The second lead screw mechanism 221 is located at the bottom of the third support frame 234. The third support frame 234 has third guide rails 222 on both sides. A third slider is slidably connected to the third guide rail 222. The third slider is fixedly connected to the support plate 211. A connecting plate 224 is fixedly provided on the support plate 211. The second lead screw mechanism 221 has a liftable push rod. The push rod passes through the connecting plate 224 and is fixedly connected to the second limiting block 225. A third limiting block 226 is fixedly provided on the push rod located below the connecting plate 224. A second spring 223 is sleeved on the push rod located between the connecting plate 224 and the third limiting block 226.

[0046] The push rod of the second lead screw mechanism 221 can drive the second limit block 225 to rise and fall, thereby driving the entire pantograph head 214 to rise and fall. A second spring 223 is provided in the mechanism to transfer the impact force received by the pantograph head 214 to the second spring 223, further improving the buffering effect.

[0047] The precise lifting and lowering control of the pantograph body 210 is achieved through the cooperation of the second lead screw mechanism 221 and the guide rail; the design of the second spring 223 further enhances the buffering effect during the lifting and lowering process, ensuring stable contact pressure of the pantograph on the contact line, reducing the generation of electric arcs, and extending the service life of the components.
