[0025] The present invention proposes a vehicle body structure reinforcement device. In the development of a whole vehicle, digital simulation technology is often used to develop the whole vehicle, and some problems are solved with the help of digital simulation. The digital simulation results sometimes show that the strength between two sheet metal parts of the vehicle body is insufficient, and it is necessary to support the two sheet metal parts to strengthen the vehicle body. Due to the errors in digital simulation technology, it is often necessary to support and strengthen the two sheet metal parts in the whole vehicle entity to observe whether the problem has been solved. When strengthening the two sheet metal parts with the help of samples, it is often difficult to find matching samples, and the samples need to be trial-produced according to the needs. The trial production time of the samples is long, which makes the time required to strengthen the vehicle body longer, which is easy to prolong the cycle of vehicle body research and development.

[0026] See also Figure 1 and Figure 2 In one embodiment of the present invention, the automobile body structure reinforcement device includes a telescopic rod 1, which is used to reinforce the space between two sheet metal parts 8 of the vehicle body, and the telescopic rod 1 is used to be arranged on the side where the two sheet metal parts 8 are close to each other; the two ends of the telescopic rod 1 are respectively connected to a base 2, and a side of the base 2 away from the telescopic rod 1 is provided with a plurality of fixing parts 3, and the plurality of fixing parts 3 are respectively telescopically installed on the base 2, and the fixing parts 3 are used to be fixed on the sheet metal part 8.

[0027] The technical solution of the present invention strengthens the vehicle body by adopting a telescopic rod 1. When strengthening the space between two sheet metal parts 8 according to the simulation results, the telescopic rod 1 can be first placed between the two sheet metal parts 8 to be strengthened. The two sheet metal parts 8 to be strengthened are mostly directly or indirectly connected, and the two ends of the telescopic rod 1 are respectively directed to the two sheet metal parts 8 to be strengthened, and then the telescopic rod 1 is controlled to extend, so that the two bases 2 are respectively close to the two sheet metal parts 8. When the fixing part 3 on the base 2 is against the sheet metal part 8, the multiple fixing parts 3 are controlled to move telescopically respectively, so that the multiple fixing parts 3 can be fitted to the curved surface on the outside of the sheet metal part 8, and the fixing part 3 is against the outside of the sheet metal part 8, which can enhance the connection effect between the base 2 and the sheet metal part 8; finally, the telescopic movement of the telescopic rod 1 is locked, and the telescopic rod 1, the base 2 and the fixing part 3 cooperate to support the space between the two sheet metal parts 8, so that the space between the two sheet metal parts 8 is strengthened relatively quickly, and the vehicle body is strengthened, which improves the problem of a long time required for strengthening the vehicle body as a whole.

[0028] Multiple fixing parts 3 are arranged at equal intervals on the base 2. By increasing the number of fixing parts 3 per unit area, the surface formed by the side of the multiple fixing parts 3 away from the base 2 can be more closely fitted to the outer curved surface of the sheet metal part 8, thereby enhancing the fitting effect between the fixing parts 3 and the sheet metal part 8, thereby enhancing the connection effect between the fixing parts 3 and the sheet metal part 8, and ensuring the stability of the connection between the telescopic rod 1 and the sheet metal part 8.

[0029] See also Figure 1 and Figure 2 After the surface formed by multiple fixing parts 3 is attached to the outer curved surface of the sheet metal part 8, the fixing parts 3 and the outer side surfaces of the sheet metal part 8 can match each other and provide resistance to the sliding of the base 2 along the sheet metal part 8, thereby ensuring the stability of the connection between the base 2 and the sheet metal part 8.

[0030] The side of the base 2 away from the telescopic rod 1 is a plane, and multiple telescopic parts 4 are installed on the side of the base 2 away from the telescopic rod 1. The shell of the telescopic part 4 is fixedly installed on the base 2, and the output shaft of the telescopic part 4 is fixedly connected to the fixed part 3, and the output shafts of the multiple telescopic parts 4 are parallel; by controlling the telescopic part 4, the fixed part 3 can be controlled to move away from or close to the base 2, thereby realizing the telescopic installation of the fixed part 3.

[0031] The base 2 can be a round block or a rectangular block. The size of the telescopic member 4 is related to the size of the selectable fixing member 3. The maximum cross-section of the fixing member 3 along its telescopic direction is not larger than the maximum cross-section of the telescopic member 4. While ensuring the structural strength, by adopting a smaller telescopic member 4, more telescopic members 4 can be installed on the base 2 while the size of the selected base 2 remains unchanged, the size of the fixing member 3 is correspondingly reduced, and the number of fixing members 3 installed is increased.

[0032] The size of the fixing member 3 is reduced, so that the size of the connection surface of each fixing member 3 that can be connected to the sheet metal member 8 is reduced, the number of fixing members 3 is increased, and the total area of ​​the connection surfaces of the multiple fixing members 3 used to connect to the sheet metal member 8 remains unchanged. When the fixing members 3 are respectively connected to the sheet metal member 8, the multiple fixing members 3 are respectively telescopically moved, so that the connection surfaces of the multiple fixing members 3 can be more closely fitted to the curved surface outside the sheet metal member 8, thereby increasing the connection area between the base 2 and the sheet metal member 8, and ensuring the connection strength between the base 2 and the sheet metal member 8.

[0033] A larger base 2 may also be selected to increase the installable area of ​​the base 2 by enlarging the base 2. When the installable area of ​​the base 2 is increased, more telescopic parts 4 can be installed on the base 2 without selecting telescopic parts 4 of other sizes, thereby enhancing the connection strength between the base 2 and the sheet metal part 8 and reducing the falling-off and separation between the base 2 and the sheet metal part 8.

[0034] The extension and retraction of the multiple retractable parts 4 are controlled by a neural network, and the extension and retraction distance of each retractable part 4 is controlled respectively, so as to ensure that each fixing part 3 is attached to the sheet metal part 8 .

[0035] The fixing member 3 is an adsorption member, which can be adsorbed on the sheet metal member 8. The connection between the base 2 and the sheet metal member 8 is relatively convenient, which simplifies the operation.

[0036] The telescopic part 4 can be a cylinder or an electric push rod, both of which can push the fixed part 3 closer to or away from the base, thereby realizing the telescopic movement of the fixed part 3. When the fixed part 3 moves to a suitable position, the telescopic movement of the fixed part 3 can be stopped by controlling the telescopic part 4, so that the positions of multiple fixed parts 3 can be kept stable.

[0037] In the present application, the telescopic member 4 is preferably an electric push rod, which is relatively common and can be used as long as it is powered on. When the electric push rod needs to be powered, an external power supply can be used or a battery can be installed on the device, and the wiring of the wires is relatively convenient, which makes the device portable and easy to use, and the operation is relatively convenient. When the device is supported between two sheet metal parts 8, a battery can be installed on the device, and the battery can directly power the device, reducing the routing and wiring problems of the wires when the external power supply is used.

[0038] When the telescopic rod 1 is supported between two sheet metal parts 8, each telescopic part 4 at both ends of the telescopic rod 1 is controlled to extend so that each adsorption part 4 can be adsorbed on the sheet metal part 8 as much as possible, and then the telescopic part 4 is controlled to stop extending and retracting so that each adsorption part 4 can be more stably attached to the sheet metal part 8.

[0039] The combination of the base 2 and the telescopic part 4 can be replaced with a robot. The selected robot must meet the support strength requirements, and the robot can allow the adsorption part to telescope and move along the surface curve of the sheet metal part 8 to ensure that each adsorption part is adsorbed on the sheet metal part 8 as much as possible.

[0040] The adsorption component is a magnetic component, which can be adsorbed on the sheet metal component 8. The fixing component is adsorbed on the plate component 8 through the direction of magnetic attraction, which is convenient to operate.

[0041] The adsorption member may also be a suction cup. The body of the suction cup is mostly made of a flexible material, has a certain degree of flexibility, can bend and deform to a certain extent, and can be well attached to a curved surface. The outer side of the sheet metal part 8 is mostly a curved surface. When the suction cup is adsorbed on the sheet metal part 8, the body of the suction cup is bent and deformed, so that the body of the suction cup is attached to the surface of the sheet metal part 8, thereby ensuring the adsorption effect between the suction cup and the sheet metal part 8.

[0042] The magnetic member is preferably a permanent magnet, and in use, the magnetic member can be conveniently adsorbed onto the sheet metal member 8. The adsorbing member is adsorbed onto the sheet metal member 8 by magnetic attraction, and the connection between the adsorbing member and the sheet metal member 8 is convenient. When the adsorbing member needs to be removed from the sheet metal member 8, the adsorbing member can also be conveniently removed from the sheet metal member.

[0043] The magnetic attraction part can also be an electromagnet. The magnetism of the electromagnet is easy to control. After the electromagnet is adsorbed on the sheet metal 8, the magnetic force of the electromagnet can be increased by enhancing the power supply of the electromagnet, thereby improving the adsorption effect of the electromagnet on the sheet metal 8 and reducing the end of the telescopic rod 1 from falling off the sheet metal 8, thereby interfering with the stable support of the security device between the two sheet metals 8; when it is necessary to release the adsorption between the electromagnet and the sheet metal 8, the magnetic force of the electromagnet can be weakened by turning off the electromagnet. After the electromagnet is turned off, the magnetic force is reduced, and the adsorption effect between the electromagnet and the sheet metal 8 is weakened, thereby facilitating the removal of the electromagnet from the sheet metal 8.

[0044] See also Figure 1 The telescopic rod 1 includes a support tube 11 and a support column 12. The support tube 11 is coaxial with the support column 12, and one end of the support tube 11 has an opening. One end of the support column 12 is inserted into the support tube 11 through the opening of the support tube 11. The support tube 11 is provided with a driving member 5 for driving the support column 12 to slide into or out of the support tube 11. When the driving member 5 drives the support column 12 to move in the direction of sliding into the support tube 11, the length of the support column 12 sliding into the support tube 11 increases, which can reduce the length of the telescopic rod 1; when the driving member 5 drives the support column 12 to move in the direction of sliding out of the support tube 11, the length of the support column 12 sliding out of the support tube 11 increases, which can increase the length of the telescopic rod 1.

[0045] The support tube 11 is a cylinder, the support column 12 is a cylinder, the driving member 5 is used to drive the support column 12 to rotate, the inner wall of the support tube 11 is provided with an internal thread, the side wall of the support column 12 is provided with an external thread, and the support tube 11 is threadedly connected with the support column 12. When the driving member 5 drives the support column 12 to rotate, the support column 12 and the support tube 11 rotate relative to each other, so that the support column 12 can slide into or out of the support tube 11; after the driving member 5 is stopped, the rotation of the support column 12 stops, and the support column 12 and the support tube 11 can be mutually locked, so that the length of the telescopic rod 1 can remain unchanged, ensuring the stable support of the telescopic rod 1.

[0046] The support tube 11 and the support column 12 are both steel structures, which ensure the structural strength of the support tube 11 and the support column 12, and ensure the stable support of the telescopic rod 1 between the two sheet metal parts 8. Furthermore, the thickness of the tube wall of the support tube 11 is greater than two millimeters, and the strength of the support tube 11 can be guaranteed.

[0047] In use, when the two ends of the telescopic rod 1 are connected to the two sheet metal parts 8 respectively, the size of the supporting force of the telescopic rod 1 on the two sheet metal parts 8 depends on the length of the telescopic rod 1. When the supporting force of the telescopic rod 1 on the two sheet metal parts 8 is large, it is easy to cause the sheet metal parts 8 to deform. When the sheet metal parts 8 are inelastically deformed, it is easy to cause destructive effects on the verification of the simulation results, thereby affecting the accuracy of the verification results; when the supporting force of the telescopic rod 1 on the two sheet metal parts 8 is small, it is difficult to ensure the supporting effect of the telescopic rod 1 on the two sheet metal parts 8; it is often necessary to fine-tune the length of the telescopic rod 1, and a handle can be welded on the support rod. The handle is welded to the end of the support column 12 away from the support tube 11. After holding the handle, the support column 12 can be rotated more conveniently. The operator can manually rotate the support column 12 to achieve fine-tuning of the length of the telescopic rod 1.

[0048] The driving member 5 is a motor, which is a through-type linear screw stepper motor. The output shaft of the motor is coaxially connected to the support column 12, the motor housing is fixedly connected to the support tube 11, the output shaft of the motor is located in the support tube 11, and the output shaft of the motor is coaxial with the support tube 11. The installation position of the motor housing is adjacent to the opening of the support tube 11, and the output shaft of the motor is integrally connected to the support column 12.

[0049] Starting the motor can cause relative rotation between the support column 12 and the support tube 11, thereby driving the support column 12 to slide into or out of the support tube 11; after stopping the motor, the support column 12 and the support tube 11 stop rotating, and the support column 12 and the support tube 11 are locked. A controller 6 is fixedly installed on the outside of the support tube 11, and the controller 6 is electrically connected to the motor. The controller 6 is provided with a plurality of control buttons, and the opening and closing and forward and reverse rotation of the motor can be controlled by the controller 6. The controller 6 can also be connected to the telescopic member 4 by electrical signals, thereby controlling the telescopic member 4 to extend and retract.

[0050] See also Figure 1 and Figure 2 When the telescopic rod 1 supports two sheet metal parts 8, there will be an inclination between the curved surface of the sheet metal part 8 close to the telescopic rod 1 and the telescopic rod 1. The base 2 is hinged at one end of the telescopic rod 1, and the hinge axis of the base 2 is perpendicular to the axis of the telescopic rod 1. By controlling the base 2 to rotate along the hinge axis, the side of the base 2 close to the sheet metal part 8 can be parallel to the side of the sheet metal part 8 close to the base 2; after the fixing part 3 is connected to the sheet metal part 8, the contact area between the fixing part 3 and the sheet metal part 8 can be increased, which is conducive to ensuring the connection strength between the base 2 and the sheet metal part 8.

[0051] The two ends of the telescopic rod 1 are respectively connected to the connecting seats 7 for coaxial rotation, one connecting seat 7 is coaxially connected to the end of the support column 12 away from the support tube 11, and the other connecting seat 7 is coaxially connected to the end of the support tube 11 away from the support column 12; the two connecting seats 7 are located between the two bases 2, and the two connecting seats 7 are arranged one-to-one with the two bases 2, and the base 2 is hinged to the corresponding connecting seats 7. When the connecting seat 7 is rotated, the base 2 and the hinge axis of the base 2 rotate with the base 2 connecting seat 7, so that the hinge axis of the base 2 can be parallel to the inclined surface of the side of the sheet metal 8 close to the base 2, and then the base 2 is controlled to rotate along the hinge line, so that the inclination direction of the side of the base 2 close to the sheet metal 8 can be parallel to the inclination direction of the side of the sheet metal 8 close to the base 2.

[0052] In another feasible embodiment, one base 2 is directly ball-jointed at one end of the support column 12 away from the support tube 11, and the other base 2 is directly ball-jointed at one end of the support tube 11 away from the support seat; the ball-jointed connection method increases the rotation range of the base 2. When the base 2 needs to be pressed against the outer surface of the sheet metal 8, the base 2 can rotate, and the inclination direction of the plane of the base 2 away from the telescopic rod 1 is parallel to the inclination direction of the outer surface of the sheet metal 8.

[0053] In one embodiment, the driving member 5 can be a rotating ring, which is coaxially rotatably connected to the open end of the support tube 11, and an internal thread is provided on the inner side wall of the rotating ring, and the rotating ring is threadedly adapted to the support column 12. The relative rotation between the rotating ring and the support column 12 can drive the support column 12 to slide into and out of the support tube 11. When the rotating ring and the support column 12 stop rotating, the rotating ring can be relatively locked with the support column 12, thereby realizing the locking of the movement of the support column 12. A limiting groove is provided on the outer side wall of the support column 12 near one end of the support tube 11, and the length direction of the limiting groove is parallel to the length direction of the support column 12. A limiting block is fixedly connected to the inner side of the support tube 11, and the limiting block is slidably adapted to the limiting groove, and the limiting block is located in the limiting groove. When the rotating ring is rotated, the rotation of the support column 12 can be limited by means of the limiting block, and the relative rotation between the support tube 11 and the support column 12 can be avoided.

[0054] During the development experiment of the whole vehicle, when there is a problem with the whole vehicle, such as a loud roaring sound from the vehicle body, digital simulation technology is used to assist in development, and the cause of the loud roaring sound from the vehicle body is found through simulation. When the simulation result shows that the strength between the two sheet metal parts 8 is low, since there is a certain error in the simulation, the simulation result needs to be verified to reduce the error. In order to verify the simulation results, it is necessary to strengthen the space between the two sheet metal parts 8, and use the device of the present application to strengthen the support between the two sheet metal parts 8 to improve the structural strength between the two sheet metal parts 8; then the whole vehicle is tested again to observe whether the roaring sound of the vehicle body is reduced. If the roaring sound of the vehicle body is reduced, it means that the simulation result is correct. In subsequent processing, the two sheet metal parts 8 can be adjusted, or the vehicle body can be adaptively adjusted to reduce the problem of the roaring sound of the vehicle body. If the roaring sound is not solved, the problem is re-located through simulation.

[0055] In the development of the whole vehicle, the problem is quickly located through the digital simulation technology, and then the simulation results are verified with the help of this device. The problems located by the digital simulation technology can be quickly verified, which improves the ability to locate problems and the speed of verifying problems in the development of the whole vehicle, reduces the time required for qualitative problems in the development of the whole vehicle, and overall reduces the time required for vehicle development and speeds up the speed of vehicle development.
