Description

Technical Field

[0001] This utility model relates to vehicle assembly, specifically to a top cover assembly flipping tool. Background Technology

[0002] Modified vehicles include various application types such as motorhomes (travel vehicles), survey vehicles (police or fire vehicles), and sightseeing vehicles (special vehicles for scenic areas). Typically, the roof assembly of these modified vehicles includes a roof body for covering the top of the vehicle body, and the roof assembly also includes a roof interior and / or lifting transmission mechanism located on the side of the roof body facing the inside of the vehicle (i.e., downward).

[0003] In the final assembly process of modified vehicles, to balance assembly convenience and installation accuracy, the assembly procedure for the roof assembly is as follows: First, the roof body is placed on the assembly platform with its interior side facing upwards. Then, workers assemble the roof interior trim and / or lifting transmission mechanisms and other components to their designated positions on the roof body, completing the roof assembly assembly. Next, the assembled roof assembly is flipped so that its interior side faces downwards. Finally, the roof assembly is lifted to its corresponding assembly position on the vehicle body using hoisting equipment, achieving integration between the roof assembly and the vehicle body. Existing technology typically requires at least two workers to manually flip the roof assembly (at least one worker on each side of the front and rear), which is inconvenient, labor-intensive, and affects overall vehicle assembly efficiency.

The front and rear parts of the flipping component are respectively connected to the first bracket and the second bracket. The flipping component is spaced apart above the base, and a receiving space is formed between the flipping component and the base. The lifting component is connected to the flipping component and is located on the side of the flipping component facing the receiving space.

[0006] Furthermore, the flipping assembly includes a flipping drive mechanism, a flipping component, a first bearing seat, and a second bearing seat. The flipping component includes a flipping base and two rotating shafts. The first bearing seat is fixedly connected to the first bracket, and the second bearing seat is fixedly connected to the second bracket. The front and rear sides of the flipping component are rotatably engaged with the first bearing seat and the second bearing seat, respectively. The flipping drive mechanism is drivenly connected to the flipping base.

[0007] Furthermore, the two rotating shafts are rotatably engaged with the first bearing seat and the second bearing seat respectively, and the flipping drive mechanism is connected to one of the rotating shafts in a transmission manner; wherein, the axes of the two rotating shafts are collinear.

Detailed Implementation

[0018] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-7As shown, a top cover assembly flipping fixture in this embodiment includes a base 1, a first bracket 2, a second bracket 3, a flipping component 4, and a lifting component 5. The first bracket 2 and the second bracket 3 are spaced apart on the base 1 in the front-rear direction. The front and rear parts of the flipping component 4 are respectively connected to the first bracket 2 and the second bracket 3. The flipping component 4 is spaced apart above the base 1, and a receiving space 6 is formed between the flipping component 4 and the base 1. The lifting component 5 is connected to the flipping component 4 and is located on the side of the flipping component 4 facing the receiving space 6.

[0020] like Figure 8 As shown, the modified vehicles include various application types such as RVs, survey vehicles, and sightseeing vehicles. The roof assembly includes a roof body for covering the top of the vehicle body, and also includes a roof interior panel and / or a lifting transmission mechanism 10 disposed on the side of the roof body facing the interior of the vehicle. After applying the roof assembly flipping fixture in this embodiment, the assembly process of the roof assembly in the modified vehicle assembly flow is as follows: S1. Place the roof body 9 on the base 1 of the roof assembly flipping fixture with the side facing upwards towards the inside of the vehicle. At this time, the lifting component 5 of the roof assembly flipping fixture is in its initial state. Figures 1-4 As shown, the top cover connecting seat 502 of the lifting assembly 5 rises to a position close to the flipping assembly 4; S2. Assemble the interior trim and / or lifting transmission mechanism 10 and other components into the preset positions of the top cover body 9 to complete the assembly of the top cover assembly; S3. The top cover connecting seat 502 of the lifting component 5 is lowered to a position away from the flipping component 4. After the top cover connecting seat 502 is connected to the top cover assembly, the top cover assembly is raised to a position close to the lower side of the flipping component 4 by the top cover connecting seat 502 of the lifting component 5. S4. The lifting assembly 5 and the top cover assembly are rotated 180° by the flipping assembly 4. The lifting assembly 5 and the top cover assembly are rotated to the top of the flipping assembly 4, so that the assembled top cover assembly is flipped, that is, the side of the top cover body 9 facing the inside of the vehicle is turned downward. S5. Connect the hoisting equipment to the roof assembly and separate the roof assembly from the lifting component 5. Hoist the roof assembly to the corresponding assembly position on the vehicle body using the hoisting equipment to achieve the assembly and integration of the roof assembly and the vehicle body. S6. By rotating the lifting assembly 5 and the top cover assembly by 180° through the flipping assembly 4, the assembled top cover assembly is flipped, so that the lifting assembly 5 is located under the flipping assembly 4, and the lifting assembly 5 of the top cover assembly flipping fixture is returned to its initial state. S7. Repeat S1-S6.

[0021] The base 1 provides support for the top cover body 9. After the top cover assembly is assembled on the base 1, the top cover assembly can be flipped by the lifting component 5 and the flipping component 4. Compared with the traditional method of two workers working together to manually flip it, the degree of automation is greatly improved, which can reduce the labor intensity of workers and improve the assembly efficiency of the whole vehicle.

[0022] In this embodiment, the flipping assembly 4 includes a flipping drive mechanism, a flipping component, a first bearing seat 401 and a second bearing seat 402. The first bearing seat 401 is fixedly connected to the first bracket 2, and the second bearing seat 402 is fixedly connected to the second bracket 3. The front and rear sides of the flipping component are rotatably engaged with the first bearing seat 401 and the second bearing seat 402 respectively. The flipping drive mechanism is drivenly connected to the flipping base.

[0023] The number of first bearing seats 401 and second bearing seats 402 can be one or more. In this embodiment, there is one first bearing seat 401 and two second bearing seats 402. The first bearing seats 401 and the second bearing seats 402 provide support for the flipping component, ensuring that the flipping component can be stably supported when it rotates.

[0024] In this embodiment, the flipping component includes a flipping base and two rotating shafts 403. The two rotating shafts 403 are rotatably engaged with the first bearing seat 401 and the second bearing seat 402, respectively. The flipping drive mechanism is connected to one of the rotating shafts 403. The axes of the two rotating shafts 403 are collinear. The flipping base rotates about the axis of the rotating shaft 403. It is worth noting that the two rotating shafts 403 can also be joined together in the front-back direction to form a whole. In this embodiment, the two rotating shafts 403 are separate, which saves materials and helps to reduce the total weight of the flipping component.

[0025] In this embodiment, the flipping base includes a rectangular frame 404 and at least two reinforcing rods 405 disposed within the rectangular frame 404, and the rotating shaft 403 is fixedly connected to the rectangular frame 404 and one of the reinforcing rods 405.

[0026] By simultaneously fixing the rotating shaft 403 with the reinforcing rod 405 and the rectangular frame 404, the connection strength between the rotating shaft 403 and the flip base can be guaranteed.

[0027] In this embodiment, the flipping drive mechanism includes a first drive element 406 and a reduction gearbox 407. The power output end of the first drive element 406 is connected to the power input end of the reduction gearbox 407, and the power output end of the reduction gearbox 407 is connected to one of the rotating shafts 403.

[0028] The first drive element 406 can be an existing rotary motor or other drive elements capable of outputting torque, and the reduction gearbox 407 can be an existing two-stage gear reduction gearbox 407 or other reduction gearbox 407 with reduction and torque amplification functions. The first drive element 406 outputs torque, which, after being reduced and amplified by the reduction gearbox 407, drives one of the rotating shafts 403 to rotate, thereby driving the tilting assembly 4, the lifting assembly 5, and the top cover assembly to rotate.

[0029] In order to make the layout of the tilting drive mechanism more reasonable, the first drive element 406 and the gearbox 407 are both located near the first bearing seat 401, that is, the first drive element 406 and the gearbox 407 are arranged on the first bracket 2.

[0030] In this embodiment, the lifting assembly 5 includes at least two lifting mechanisms spaced apart along the front-rear direction. Each of the at least two lifting mechanisms includes a mounting base 501, a top cover connecting base 502, a second driving element 503, and two hinge rods 504. The middle parts of the two hinge rods 504 are hinged to form an "X" shape. The upper ends of the two hinge rods 504 are hinged to the mounting base 501, and the lower ends of the two hinge rods 504 are hinged to the top cover connecting base 502. The mounting base 501 is fixed to the side of the flipping assembly 4 facing the receiving space 6. The second driving element 503 is used to change the included angle between the two hinge rods 504 so that the top cover connecting base 502 moves closer to or away from the mounting base 501.

[0031] The second drive element 503 can be an existing telescopic cylinder or other telescopic drive element. Both ends of the second drive element 503 are hinged to two hinge rods 504 respectively. When the second drive element 503 shortens, the mounting points of the second drive element 503 on the two hinge rods 504 move closer together, and the angle between the two hinge rods 504 decreases, allowing the top cover connecting seat 502 to move closer to the mounting seat 501. When the second drive element 503 extends, the mounting points of the second drive element 503 on the two hinge rods 504 move further apart, and the angle between the two hinge rods 504 increases, allowing the top cover connecting seat 502 to move further away from the mounting seat 501.

[0032] The top cover connecting seat 502 is used to connect with the top cover body 9. Specifically, multiple top cover mounting points for connecting with the vehicle body are reserved on the top cover body 9, and the top cover connecting seat 502 is provided with connection holes for the top cover mounting points at the corresponding positions of the top cover mounting points.

[0033] In this embodiment, the lifting assembly 5 further includes buffer seats 505 disposed on the left and right sides of each lifting assembly 5, one end of which is connected to the flipping assembly 4. The buffer seats 505 are made of flexible materials such as rubber, and when the lifting assembly 5 drives the top cover assembly to rise to a position close to the lower side of the flipping assembly 4, it can prevent the top cover assembly from colliding or rubbing against the tooling.

[0034] In this embodiment, a proximity sensor is provided on the buffer seat 505. To control the first driving element 406 and the second driving element 503, the top cover assembly flipping fixture also includes a control cabinet 8 located above the first driving element 406. The control cabinet 8 is equipped with a switch button and a controller. In response to the triggering operation of the switch button, the controller can issue control commands to control the extension and retraction state of the second driving element 503 and to control the start and stop of the first driving element 406. The proximity sensor can detect the position of the top cover assembly. When the top cover assembly rises to a predetermined position, the proximity sensor can send a signal to the controller. After receiving the signal, the controller issues a control command to stop the extension of the second driving element 503.

[0035] In this embodiment, the base 1 includes two longitudinal beams 101 and multiple transverse beams 102. The two longitudinal beams 101 are spaced apart in the left-right direction, and the multiple transverse beams 102 are spaced apart between the two longitudinal beams 101 in the front-back direction. None of the transverse beams 102 are located directly below the rectangular frame 404. To prevent the transverse beams 102 from being directly below the rectangular frame 404, the following technical solution can be adopted: the transverse beams 102 can be arranged below the first support 2 or the second support 3.

[0036] The first bracket 2 and the second bracket 3 are used to raise the height of the rotation axis of the flipping assembly 4, ensuring the distance between the flipping assembly 4 and the base 1, and preventing interference between the top cover assembly and the base 1 during the 180° rotation in S4. Furthermore, none of the crossbeams 102 are located directly below the rectangular frame 404, which reduces the height requirements of the rotation axis of the flipping assembly 4. Specifically, during the rotation of the top cover assembly in process S4, when the top cover assembly rotates 90°, its lowest point is at its lowest point above the ground. If the base 1 is flat or has a crossbeam 102 in its middle, the height of the rotation axis of the flipping component 4 needs to satisfy the following: after the top cover assembly is raised in process S3, the distance between the lower end face of the top cover assembly and the upper surface of the base 1 is greater than half the width of the top cover assembly. However, by adopting the technical solution in this embodiment where none of the crossbeams 102 are located directly below the rectangular frame 404, the space between the two longitudinal beams 101 can provide clearance. Therefore, the height of the rotation axis of the flipping component 4 only needs to satisfy the following: after the top cover assembly is raised in process S3, the distance between the lower end face of the top cover assembly and the ground is greater than half the width of the top cover assembly. Therefore, by adopting the technical solution where none of the crossbeams 102 are located directly below the rectangular frame 404, the amount of steel pipes used in the first support 2 and the second support 3 can be reduced.

[0037] In this embodiment, rollers 7 are also provided below the base 1. The rollers 7 are preferably existing rollers with braking and locking functions. Several rollers 7 are provided below both longitudinal beams 101, which makes it easy for workers to move the tooling to the required position.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
