[0028] The utility model discloses the range extending device connecting platform and vehicle will be clearly, completely described, obviously, the following described embodiment is a part of the embodiment of the utility model, not all embodiments. Figures 1 to 3 The utility model discloses the range extending device connecting platform and vehicle will be clearly, completely described, obviously, the following described embodiment is a part of the embodiment of the utility model, not all embodiments.

[0029] The utility model discloses a range extending device connecting platform, including bearing station 100 and suspension assembly.

[0030] Referring to Figure 1 The bearing station 100 is in the form of a plate arranged horizontally, and is provided with a mounting structure 101 for mounting the range extending device of the vehicle, so that the range extending device can be mounted on the upper side of the bearing station 100. The bearing station 100 can be made of metal material to provide sufficient bearing capacity. The mounting structure 101 includes a plurality of mounting holes, and the components such as air compressor and water pump of the range extending device can be mounted in the mounting holes through bolt connection pairs. The mounting structure 101 can also be provided with a variety of hole layout to flexibly connect a variety of components and adapt to the splicing combination of a variety of accessories, so as to provide more possibilities for the overall vehicle layout, facilitate the arrangement scheme, and support the platform construction. The suspension assembly is also connected with the bearing station 100 through a plurality of bolt connection pairs. The bolt connection pair includes a bolt component and a nut component. A sandwich cavity 103 can be arranged in the bearing station 100 to reduce the weight of the bearing station 100. The sandwich cavity 103 can be used to place the nut component, so that the tail of the nut component and the bolt component are arranged in the sandwich cavity 103, and the tail of the nut component and the bolt component will not protrude from the surface of the bearing station 100, so that the surface of the bearing station 100 is relatively flat, and the components of the range extending device can be placed conveniently. Of course, in some other embodiments of the utility model, the bearing station 100 can also be a solid plate.

[0031] The suspension assembly includes a plurality of suspension components, which are used to connect the carrier platform 100 and the vehicle body. The plurality of suspension components are arranged on the edge of the carrier platform 100, and the plurality of suspension components are arranged at the bottom of the carrier platform 100, so that the weight of the range extender and the carrier platform 100 can be distributed to the plurality of suspension components, and the stability of the carrier platform is better; wherein, at least one suspension component is a bushing suspension 200. It can be understood that the conventional bushing suspension 200 includes a core shaft 210, a bushing body 220 sleeved on the outside of the core shaft 210, and an outer cylinder 230 sleeved on the outside of the bushing body 220. With the driving direction of the vehicle as the front of the carrier platform 100, the axial direction of the bushing suspension 200 is horizontal, that is, the core shaft 210, the bushing body 220 and the outer cylinder 230 are sleeved on the outside of the bushing body 220. 0 and the axial directions of the outer cylinder 230 are both horizontal, the core shaft 210 is connected to the bearing platform 100, and the outer cylinder 230 is connected to the vehicle body; the bushing suspension 200 has a greater constraint on the core shaft 210 along the radial direction of the bushing body 220, that is, the front and rear displacement and vertical displacement of the bearing platform 100 are greatly restricted, and the bushing suspension 200 has a smaller constraint on the core shaft 210 along the axial direction of the rubber bushing, that is, the lateral displacement of the bearing platform 100 is smaller. In this embodiment, by setting the axial direction of the bushing suspension 200 perpendicular to the driving direction of the vehicle, the bushing suspension 200 can limit the front and rear displacement of the range extender and the bearing platform 100 caused by acceleration and deceleration of the vehicle, and the bushing suspension 200 can also provide sufficient support for the weight of the range extender and the bearing platform 100.

[0032] Two of the suspension components are rubber suspensions 300, which are spaced apart in the transverse direction. Each rubber suspension 300 has a columnar rubber block 320. The two columnar rubber blocks 320 are tilted, and the axial extension lines of the two columnar rubber blocks 320 intersect. The columnar rubber block of the rubber suspension on the left is called the left rubber block, and the columnar rubber block of the rubber suspension on the right is called the right rubber block. The left rubber block is tilted upward from left to right, and the right rubber block is tilted downward from left to right, so that the rubber suspension on the left extends from the left edge of the support platform 100 to the lower left, and the rubber suspension on the right extends from the right edge of the support platform 100 to the lower right, so that there is still enough space under the support platform 100 to arrange structures such as the drive shaft, exhaust pipe, and drain pipe. The rubber block 320 can provide vertical and lateral support forces for the load-bearing platform 100. By setting the axial extension lines of the two columnar rubber blocks 320 to intersect, the directions of the lateral support forces provided by the two columnar rubber blocks 320 to the load-bearing platform 100 are opposite. The two rubber suspensions 300 can limit the lateral displacement of the load-bearing platform 100, making up for the deficiency of the bushing suspension 200 in limiting the lateral position of the load-bearing platform 100. Of course, in some other embodiments of the present invention, the left rubber block can also be set to tilt downward from left to right and the right rubber block can be set to tilt upward from left to right.

[0033] When in use, components of a range-extending device such as an air compressor, a water pump or an internal combustion engine can be arranged on the bearing table 100, and the vibration generated when the components such as the air compressor, the water pump or the internal combustion engine are running can be blocked by the plurality of suspension components, thereby improving the driving experience of the driver; meanwhile, the bushing suspension 200 can provide sufficient restriction on the front-to-back displacement and the vertical displacement of the bearing table 100, and the two rubber suspensions 300 can provide sufficient restriction on the lateral displacement of the bearing table 100, so that the suspension assembly can stably support the bearing table 100 in each direction.

[0034] In some embodiments of the utility model, the bushing suspension 200 is arranged at the rear side of the bearing table 100, and the rubber suspension 300 is arranged at the front side of the bearing table 100. It can be understood that when the front-wheel-steering vehicle is steering, the lateral deviation tendency of the components close to the vehicle head under the action of inertia is relatively large, so the lateral deviation tendency of the front end of the connecting platform is relatively large, and the lateral deviation tendency of the rear end is relatively small. In the present embodiment, the two rubber suspensions 300 capable of providing lateral constraint are arranged at the front side of the bearing table 100, which meets the design requirement. Meanwhile, by arranging the bushing suspension 200 at the rear side, the bushing suspension 200 is relatively far away from the two rubber suspensions 300, and the support for the bearing table 100 is relatively stable. Of course, in other embodiments of the utility model, the bushing suspension 200 can also be arranged at the front side of the bearing table 100, and the rubber suspension 300 can be arranged at the rear side of the bearing table 100.

[0035] In some embodiments of the utility model, the number of bushing suspensions 200 is two, and the two bushing suspensions 200 are arranged in a lateral direction. It can be understood that the middle part of the lower vehicle body of the range-extending vehicle needs to be arranged with components such as exhaust pipes, and the lower space of the bearing table 100 is relatively tight. By arranging two bushing suspensions 200, the two bushing suspensions 200 are respectively connected to the left side edge and the right side edge of the bearing table 100, and sufficient space for installing other components is left below the bearing table 100. Of course, in other embodiments of the utility model, the number of bushing suspensions 200 can also be one, and the bushing suspension 200 can be arranged at the middle part of the rear edge of the bearing table 100.

[0036] In some embodiments of the present invention, a connecting bracket 110 for connecting to the vehicle body is provided at the rear end of the platform 100. The connecting bracket 110 can serve as a cable tray to bundle and secure the cables leading from the range extender. Two bushing mounts 200 are located on the left and right sides of the connecting bracket 110, respectively. It should be noted that in some vehicle models, the range extender and the platform 100 are located at the vehicle's rear axle, with the rear portion of the range extender platform positioned above the vehicle's rear axle. In this embodiment, the connecting bracket 110 and the two bushing mounts 200 both protrude rearward from the rear edge of the platform 100. Utilizing the area behind the platform 100 for positioning the connecting bracket 110 and the two bushing mounts 200 avoids the problem of excessive lateral dimensions of the rear portion of the range extender platform, which would result from placing the two bushing mounts 200 on the left and right sides of the platform 100. In this embodiment, the rear portion of the range extender platform can be configured to have a smaller lateral dimension, allowing the rear portion of the range extender platform to span over the vehicle's rear axle, resulting in a more compact structure.

[0037] In some embodiments of the present invention, referring to Figure 2 As shown, the bushing suspension 200 includes a core shaft 210, a bushing body 220 that is sleeved on the outside of the core shaft 210, and an outer cylinder 230 that is sleeved on the outside of the bushing body 220. The lower side of the outer cylinder 230 is provided with a first bracket 231 for connecting to the vehicle body. The end of the core shaft 210 near the connecting frame 110 is connected to a second bracket 240. The second bracket 240 has an extension portion 241 that extends to the front of the outer cylinder 230 and is connected to the rear edge of the support platform 100. The extension portion 241 can be stacked on the bottom of the support platform 100 and connected to the support platform 100 using a bolt connection pair. By providing the extension portion 241, the bushing suspension 200 can be stably connected to the rear edge of the support platform.

[0038] In some embodiments of the present invention, the two columnar rubber blocks 320 are gradually spaced apart from each other from top to bottom, which is beneficial for leaving enough space below the supporting platform 100 to arrange other vehicle structures such as a transmission shaft, an exhaust pipe, and a drain pipe.

[0039] In some embodiments of the present invention, the rubber suspension 300 includes a first support 330 and a second support 310. The first support 330 is connected to the bottom of the columnar rubber block 320 along the axial direction of the columnar rubber block 320. The bottom of the first support 330 is provided with a first bent portion 331 bent downward, and the first bent portion 331 is used to connect to the vehicle body; the second support 310 is connected to the top of the columnar rubber block 320 along the axial direction of the columnar rubber block 320. The top of the second support 310 is provided with a second bent portion 311 bent toward a side away from the columnar rubber block 320. The second bent portion 311 is arranged horizontally and is connected to the supporting platform 100. The second bent portion 311 is stacked on the bottom of the supporting platform 100 and is connected to the supporting platform 100 through a bolt connection pair. Taking the rubber suspension on the right side as an example, refer to Figure 3 As shown, the second support 310 is located at the right end of the second bend 311, and the cylindrical rubber block 320 is located at the lower right end of the second support 310. The cylindrical rubber block 320 is arranged downwardly and tilted from left to right. The first support 330 is located at the lower right end of the cylindrical rubber block 320. The first support 330 and the cylindrical rubber block 320 can stably transmit force along the axial direction of the cylindrical rubber block 320, and the second support 310 and the cylindrical rubber block 320 can stably transmit force along the axial direction of the cylindrical rubber block 320, resulting in a stable structure. By providing the first bracket 231 on the lower side of the outer cylinder 230 for connection to the vehicle body and the first bend 331 at the bottom of the first support 330 for connection to the vehicle body, the range extender device connection platform can be vertically installed on the vehicle chassis, facilitating vehicle production and assembly.

[0040] In some embodiments of the present invention, the mounting structure 101 is disposed on the rear side of the carrier platform 100. This allows the gravity of the range extender to primarily act on the rear side of the carrier platform 100, placing the center of gravity of the carrier platform 100 and the range extender closer to the bushing mount 200. The overall weight of the carrier platform 100 and the range extender is primarily borne by the bushing mount 200, which has a relatively strong vertical bearing capacity, resulting in a more stable structure.

[0041] In some embodiments of the present invention, the platform 100 is provided with a hollowed-out area 102, which is located in front of the mounting structure 101. The hollowed-out area 102 is a notch formed by the front edge of the platform 100 being recessed toward the rear; this further reduces the weight of the front portion of the platform 100, allowing the overall weight of the platform 100 and the range extender to be primarily borne by the bushing suspension 200, which has a relatively strong vertical bearing capacity.

[0042] The vehicle according to the second embodiment of the present invention includes a vehicle body, a range extender, and the aforementioned range extender connection platform. The range extender is connected to a mounting structure 101, and each suspension component is connected between the vehicle body and the support platform 100. Because the vehicle includes the aforementioned range extender connection platform, the beneficial effects achieved by the aforementioned range extender connection platform can be achieved, which will not be further described here.

[0043] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
