[0035] Example 1

[0036] Reference Figure 1 As shown, this is the first embodiment of the present invention, a drive suspension bracket for an unmanned pure electric wide-body vehicle, including a bracket assembly 100, on which the drive assembly can be mounted and the bracket assembly 100 can be mounted on the vehicle frame;

[0037] Specifically, the bracket assembly 100 includes a left upper front bracket assembly 101, a right upper front bracket assembly 102 symmetrically arranged on one side of the left upper front bracket assembly 101, a left upper rear bracket assembly 103 arranged behind the left upper front bracket assembly 101, and a right upper rear bracket assembly 104 symmetrically arranged on one side of the left upper rear bracket assembly 103; wherein the left upper front bracket assembly 101, the right upper front bracket assembly 102, the left upper rear bracket assembly 103 and the right upper rear bracket assembly 104 have the same structure and are arranged symmetrically in pairs.

[0038] Furthermore, the upper left front bracket assembly 101 includes a lower suspension bracket 101a, which is generally L-shaped and has reinforcing ribs on both sides. Two connection holes for connecting to the vehicle frame are provided on one side of the lower suspension bracket 101a. A soft pad 101b is provided on the lower suspension bracket 101a, and through holes are provided on both sides of the bottom end of the soft pad 101b for installation. The soft pad 101b has a double-ended... The stud 101c is a double-ended stud. One end of the double-ended stud 101c is connected to the soft pad 101b, and the other end of the double-ended stud 101c extends above the soft pad 101b. The soft pad 101b is provided with a mounting bracket 101d, which is arranged in an inverted L shape. The top of the mounting bracket 101d is provided with two positioning holes, and the mounting bracket 101d is sleeved on the double-ended stud 101c through the positioning holes. Several mounting holes are opened on one side of the bottom end of the mounting bracket 101d for connecting with the drive assembly.

[0039] Furthermore, a crossbeam 105 is connected between the upper left rear support assembly 103 and the upper right rear support assembly 104. The crossbeam 105 is located at the top of the upper left rear support assembly 103 and the upper right rear support assembly 104 and is sleeved on the double-headed stud 101c. It can be used to increase the stability and strength of the upper left rear support assembly 103 and the upper right rear support assembly 104.

[0040] During use, the drive assembly can be connected sequentially to the upper left front bracket assembly 101, the upper right front bracket assembly 102, the upper left rear bracket assembly 103, and the upper right rear bracket assembly 104. Then, the four mounting brackets 101d can be connected to the soft pad 101b and fitted onto the double-ended studs 101c, and then limited by nuts. At the same time, when the soft pad 101b is set on the lower suspension bracket 101a, it can be fixed by using positioning bolts through the through holes on the soft pad 101b. By connecting the lower suspension bracket 101a to the vehicle frame, the drive assembly can be installed on the vehicle frame. The overall strength is high, the reliability is high, the parts are highly uniform, and the structural strength of the vehicle frame can be improved. All mounting brackets are sheet metal structural parts, which do not require mold opening and make installation simpler and faster.

[0041] Example 2

[0042] Reference Figure 2-6As shown, this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the lower suspension bracket 101a is provided with a locking unit 200 for fixing the soft pad 101b.

[0043] Specifically, the locking unit 200 includes a positioning post 201 disposed on the lower suspension bracket 101a. The positioning post 201 passes through the lower suspension bracket 101a and is fixedly connected to the lower suspension bracket 101a. The positioning post 201 is hollow inside. A pressing positioning component 202 is disposed on the positioning post 201. The pressing positioning component 202 is used to press down on the upper surface of the base of the soft pad 101b to increase stability. An inner diameter locking component 203 is disposed inside the positioning post 201. The inner diameter locking component 203 is used to abut against the inside of the through hole on the soft pad 101b to lock the inner diameter of the through hole and increase the stability of the soft pad 101b installation.

[0044] Furthermore, the pressing positioning component 202 includes a sliding sleeve 202a disposed on the positioning post 201. The upper half of the sliding sleeve 202a is solid and slidably connected to the inner wall of the positioning post 201. The lower half of the sliding sleeve 202a is a cover-shaped component. A pressing structure 202b is disposed at the top of the sliding sleeve 202a for pushing the sliding sleeve 202a downward. A first wedge block 202c and a second wedge block 202d are disposed on both sides inside the sliding sleeve 202a. The inclined surface of the second wedge block 202d is correspondingly arranged. A fixed cylinder 202e is provided inside the positioning post 201. The fixed cylinder 202e is fixedly connected to the inner wall of the positioning post 201 through a connecting frame. An irregularly shaped slider 202f is provided on the fixed cylinder 202e. The irregularly shaped slider 202f is arranged perpendicularly to the fixed cylinder 202e, penetrates the fixed cylinder 202e, and is slidably connected to the fixed cylinder 202e. Both ends of the irregularly shaped slider 202f are wedge-shaped surfaces. The connecting rod 202h-5 between the surfaces is inclined. A lifting shaft 202g is slidably connected inside the fixed cylinder 202e. The irregularly shaped slider 202f passes through the lifting shaft 202g and is slidably connected to it. A flipping structure 202h is also provided on the positioning post 201. The flipping structure 202h is connected to the lifting shaft 202g. While the sliding sleeve 202a moves downward, the first wedge block 202c and the second wedge block 202d can respectively interact with the wedge-shaped surfaces at both ends of the irregularly shaped slider 202f. The contact causes the irregularly shaped slider 202f to move. As the irregularly shaped slider 202f moves, the inclined connecting rod 202h-5 pushes the lifting shaft 202g upward, causing the compression spring 202g-1 between the lifting shaft 202g and the sliding sleeve 202a to contract. As the lifting shaft 202g moves upward, it can drive the flipping structure 202h to flip, thereby using the flipping structure 202h to press and position the upper surface of the soft pad 101b base downward.

[0045] Furthermore, the pressing structure 202b includes a fixing frame 202b-1 set on both sides of the top of the positioning column 201. A rotating shaft 202b-2 is rotatably mounted between the fixing frames 202b-1. A cam 202b-4 is fixedly sleeved on the rotating shaft 202b-2. A handle 202b-3 is fixedly connected to the rotating shaft 202b-2. The handle 202b-3 is located on both sides of the cam 202b-4. The handle 202b-3 can be rotated to make the rotating shaft 202b-2 rotate. In turn, the cam 202b-4 can rotate with the rotating shaft 202b-2 and press down on the sliding sleeve 202a, thereby achieving the pressure on the sliding sleeve 202a.

[0046] Furthermore, the flipping structure 202h includes several first through slots 202h-1 provided on the side wall of the positioning post 201. At least four first through slots 202h-1 are provided. Two pressure rods 202h-2 are rotatably installed inside each first through slot 202h-1. Both ends of each pressure rod 202h-2 are arc-shaped. A shaft connects the two pressure rods 202h-2, with both ends of the shaft rotatably connected to the inner wall of the first through slot 202h-1. A gear 202h-3 is provided between the two pressure rods 202h-2, and the gear 202h-3 is fixedly installed on the shaft. A rack 202h-4 is meshed with one side of the gear 202h-3. A connecting rod 202h-5 is fixedly connected to one side of the rack 202h-4. One end of the connecting rod 202h-5 passes through the sliding sleeve 202a and is connected to the lifting shaft 202g. The sliding sleeve 202a has a groove that matches the connecting rod 202h-5. When the lifting shaft 202g moves up or down, it drives the rack 202h-4 to move, thereby meshing the rack 202h-4 with the gear 202h-3, causing the gear 202h-3 to rotate and drive the shaft to rotate. This causes the pressing rod 202h-2 to flip, so that the pressing rod 202h-2 can press and position the base of the soft pad 101b from top to bottom.

[0047] Furthermore, the inner diameter locking assembly 203 includes a sliding member 203a disposed inside the positioning post 201. The sliding member 203a is generally frustum-shaped and is made of rubber. The sliding member 203a is slidably connected to the inner wall of the positioning post 201. Push rods 203b are provided on both sides of the upper end of the sliding member 203a. One end of the push rod 203b is fixedly connected to the sliding sleeve 202a, and the other end of the push rod 203b is fixedly connected to the upper surface of the sliding member 203a. Several second through grooves 203d are provided on the side wall of the sliding sleeve 202a. At least four second through grooves 203d are provided. The second through grooves 203d are located below the first through groove 202h-1. A rubber pad 203e is slidably disposed inside the second through groove 203d. A hinge rod 203c is connected to one side of the rubber pad 203e. The other end of the hinge rod 203c is hinged to the lower surface of the sliding member 203a.

[0048] The remaining structure is the same as that in Example 1.

[0049] During operation, the soft pad 101b can be placed on the lower suspension bracket 101a, and simultaneously, the soft pad 101b is fitted onto the positioning post 201 through its through hole. Then, the handle 202b-3 can be bent to one side, causing the handle 202b-3 to drive the rotating shaft 202b-2 to rotate. This causes the cam 202b-4 to rotate with the rotating shaft 202b-2 and press down on the sliding sleeve 202a, thereby achieving pressure on the sliding sleeve 202a and causing the sliding sleeve 202a to... As the sliding sleeve 202a moves downward, the first wedge block 202c and the second wedge block 202d on the inner wall of the sliding sleeve 202a can abut against the wedge blocks at both ends of the irregular slider 202f, causing the irregular slider 202f to move. While the irregular slider 202f moves, the inclined connecting rod 202h-5 pushes the lifting shaft 202g upward, and causes the compression spring 202g-1 between the lifting shaft 202g and the sliding sleeve 202a to contract.

[0050] As the lifting shaft 202g moves upward, it can drive the rack 202h-4 to move upward through the connecting rod 202h-5. At the same time, the rack 202h-4 can mesh with the gear 202h-3 to rotate, thereby causing the shaft to rotate and driving the pressing rod 202h-2 to flip. This allows the pressing rod 202h-2 to press and position the soft pad 101b base from top to bottom, increasing or decreasing the stability of the soft pad 101b installation.

[0051] As the sliding sleeve 202a moves downward, the sliding member 203a can be pushed downward by the push rod 203b. As the sliding member 203a moves downward, the angle of the hinge rod 203c changes. Thus, the rubber pad 203e can be pushed out through the second through groove 203d by the hinge rod 203c, so that the rubber pad 203e is in an expanded state inside the through hole on the base of the soft pad 101b. This expands and positions the through hole on the base of the soft pad 101b, further increasing the stability of the soft pad 101b installation. The overall operation is simple.

[0052] Example 3

[0053] Reference Figure 7-8As shown, this is the third embodiment of the present invention. This embodiment differs from the second embodiment in that the locking unit 200 further includes a limiting component 204. The limiting component 204 includes a rotating shaft 204a disposed at the bottom end of the sliding member 203a. One end of the rotating shaft 204a is rotatably connected to the sliding member 203a, and the other end of the rotating shaft 204a is provided with a limiting sleeve 204b. One end of the limiting sleeve 204b extends to the outside of the positioning post 201. An auxiliary knob is provided on the part of the limiting sleeve 204b located at the bottom end of the suspension lower bracket 101a, and the limiting sleeve 204b is rotatably connected to the positioning post 201. The inner wall of the limiting sleeve 204b is provided with protruding teeth, and the end of the rotating shaft 204a connected to the limiting sleeve 204b is provided with a groove. The rotating shaft 204a is slidably engaged with the limiting sleeve 204b through the protruding teeth and the groove.

[0054] Furthermore, the positioning post 201 is provided with a limiting tooth groove 204c inside, and the rotating shaft 204a is provided with a positioning tooth 204d. The positioning tooth 204d matches the limiting tooth groove 204c. When the rotating shaft 204a moves down with the sliding member 203a, the positioning tooth 204d moves to below the limiting tooth groove 204c. Then, the limiting sleeve 204b can be rotated to make the rotating shaft 204a rotate, thereby causing the positioning tooth 204d to be misaligned with the limiting tooth groove 204c, and the rotating shaft 204a is limited, thus preventing the rotating shaft 204a from moving upward.

[0055] The remaining structure is the same as that in Example 2.

[0056] During operation, when the sliding member 203a moves downward, it can push the rotating shaft 204a to move downward synchronously. At this time, the bottom end of the rotating shaft 204a slides and engages with the limiting sleeve 204b through the convex teeth and grooves. When the rotating shaft 204a moves downward, it continues to be inserted into the limiting sleeve 204b. When the rotating shaft 204a moves downward, the positioning tooth 204d on the rotating shaft 204a can pass through the limiting tooth groove 204c and be located below the limiting tooth groove 204c. At this time, the limiting sleeve 204b can be rotated by the auxiliary knob. The rotation of the limiting sleeve 204b drives the rotating shaft 204a to rotate. When the rotating shaft 204a rotates, the positioning tooth 204d on it can be misaligned with the limiting tooth groove 204c. At this time, the limiting tooth groove 204c can be used to limit the positioning tooth 204d, preventing the rotating shaft 204a, sliding member 203a, and sliding sleeve 202a from moving upward, effectively limiting the movement and increasing the stability of the connection.
