DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] As described in the background technology, in order to reduce the damage to the powertrain, this embodiment provides a protective steel frame for the powertrain of a gasoline-to-electric vehicle. The device can provide certain protection for the powertrain when the gasoline-to-electric vehicle collides, thereby reducing the probability of damage to the powertrain.

[0024] See also Figures 1 to 5 This embodiment proposes a protective steel frame for a powertrain of an oil-to-electric vehicle, including a powertrain body 1, and a horizontal steel 2 is welded on the upper surface of the powertrain body 1.

[0025] The powertrain body 1 is an existing mechanism that can play a role in power transmission in a gasoline-to-electric vehicle. Since the powertrain body 1 is not the focus of description in this application, its working principle and internal structure will not be described in detail.

[0026] A plurality of connection holes 4 are provided on both sides of the outer surface of the powertrain body 1, and two symmetrical connection grooves 5 are provided on the upper surface of the crossbar 2. By providing the connection holes 4 and the connection grooves 5, the device can be conveniently installed and connected to the oil-to-electric vehicle.

[0027] A protective mechanism 3 is provided inside the cross steel 2, and the protective mechanism 3 includes four installation grooves 301 and a cavity 302 opened in the cross steel 2. By setting the protective mechanism 3, a certain protective effect can be provided to the power train body 1. When the oil-to-electric vehicle collides, the setting of the protective mechanism 3 can effectively reduce the probability of damage to the power train body 1 and reduce the subsequent maintenance cost.

[0028] The internal rotating sleeve of the cavity 302 is provided with a bidirectional screw rod 303, and the outer surface of the bidirectional screw rod 303 is threadedly connected to two sleeve blocks 304. The two sleeve blocks 304 are symmetrically distributed. The tightening and loosening torque between the bidirectional screw rod 303 and the two sleeve blocks 304 has a certain strength to prevent the sleeve blocks 304 from moving randomly due to vibrations occurring during the driving of the oil-to-electric vehicle.

[0029] Two limiting rods 305 are fixedly connected to the side surfaces of the two sleeve blocks 304 away from each other. Two protective steel frame bodies 310 are arranged outside the cross steel 2. Two limiting grooves 311 are arranged at the installation end of each protective steel frame body 310.

[0030] The four limit rods 305 are slidably mounted in the inner walls of the four mounting grooves 301 , respectively. The mounting ends of the two protective steel frame bodies 310 are respectively matched with the inner walls of the four mounting grooves 301 , and the size values ​​of the four limit rods 305 correspond to the size values ​​of the four limit grooves 311 , respectively.

[0031] By limiting the connection relationship between the limit rod 305 and the installation groove 301, the sleeve block 304 can be made more stable during the movement. By limiting the relationship between the protective steel frame body 310 and the installation groove 301, the disassembly and assembly of the protective steel frame body 310 can be facilitated. By limiting the relationship between the limit rod 305 and the limit groove 311, the limit installation of the protective steel frame body 310 through the limit rod 305 can be facilitated.

[0032] Two limit plates 306 are fixedly connected to the outer surface of the bidirectional screw rod 303. The diameter values ​​of the two limit plates 306 are both larger than the diameter value of the bidirectional screw rod 303. By setting the limit plates 306, the movement trajectory of the sleeve block 304 can be limited to prevent the sleeve block 304 from derailing during movement, which is beneficial to the disassembly and assembly of the protective steel frame body 310.

[0033] The outer surface of the bidirectional screw 303 is fixedly connected with a first bevel gear 307, and the inner wall of the horizontal steel 2 is rotatably sleeved with a rotating rod 308, one end of which is fixedly connected with a second bevel gear 309 meshing with the first bevel gear 307.

[0034] By arranging the first bevel gear 307, the rotating rod 308 and the second bevel gear 309 to cooperate with each other, the transmission direction can be changed. The bidirectional screw rod 303 can be rotated by rotating the rotating rod 308, which is convenient for operation.

[0035] When the rotating rod 308 is rotated, the second bevel gear 309 can be driven to rotate, and the rotation of the second bevel gear 309 can make the first bevel gear 307 rotate, and then the rotation of the first bevel gear 307 can drive the two sets 304 to move closer to or away from each other.

[0036] In this way, the four limiting rods 305 can be driven to move, and the two protective steel frame bodies 310 can be limited or released, which facilitates the disassembly and assembly of the protective steel frame bodies 310, is beneficial to the subsequent replacement of the deformed protective steel frame bodies 310, and improves the practicality of the device.

[0037] The other end of the rotating rod 308 is fixedly connected with a rotating handle 6, and the outer surface of the rotating handle 6 is coated with an anti-slip coating. By setting the rotating handle 6, the contact area of ​​the rotating rod 308 can be increased, which makes it convenient for the staff to rotate the rotating rod 308 and is beneficial to the disassembly and assembly of the protective steel frame body 310.

[0038] The connecting ends of the two protective steel frame bodies 310 are respectively installed with a rectangular block 7 and a rectangular groove 8. The size value of the rectangular block 7 corresponds to the size value of the rectangular groove 8. By setting the rectangular block 7 and the rectangular groove 8, the two protective steel frame bodies 310 can be more stable when docked and installed, thereby improving the protective effect of the powertrain body 1.

[0039] Working principle: When in use, first install the two protective steel frame bodies 310 on both sides of the horizontal steel 2 respectively. When installing the two protective steel frame bodies 310, the installation ends of the two protective steel frame bodies 310 should be aligned with the corresponding limit rods 305 and inserted. At the same time, the rectangular blocks 7 and rectangular grooves 8 installed at the bottom of the two protective steel frame bodies 310 will also be combined. After completing the above-mentioned insertion combination, the handle 6 can be rotated by a wrench. When the handle 6 rotates, it will drive the rotating rod 308 and the second bevel gear 309 to rotate. When the second bevel gear 309 rotates, it will drive the first bevel gear 307 and the two-way screw rod 303 to rotate. When the two-way screw rod 303 rotates, the two sleeve blocks 304 threadedly connected on its surface will move closer to or away from each other. In this way, the movement of the two sleeve blocks 304 can make the four limit rods 305 move through the cavity 302 to the corresponding installation groove 301. The two protective steel frame bodies 310 have completed the above-mentioned insertion and combination steps, so the four limiting rods 305 will be respectively inserted into the limiting grooves 311 opened on the surfaces of the two protective steel frame bodies 310, which means that the limiting work of the two protective steel frame bodies 310 is completed. In this way, the two protective steel frame bodies 310 can be protected on the outside of the powertrain body 1 to reduce the damage to the powertrain body 1 caused by a collision of the oil-to-electric vehicle. Then the device can be installed as a whole in the oil-to-electric vehicle through the connecting hole 4 and the connecting groove 5. In the subsequent maintenance process, when the deformed protective steel frame body 310 needs to be replaced, the handle 6 can be turned by a wrench to make the two sleeves 304 move closer to each other, so that the four limiting rods 305 can be respectively moved out of the corresponding limiting grooves 311, thereby achieving the effect of releasing the limiting of the installation ends of the two protective steel frame bodies 310, and the protective steel frame body 310 can be disassembled for replacement.
