[0054] In this embodiment, the housing 1 consists of a frame and a hollow base, and the frame is located above the hollow base.

[0055] In this embodiment, box doors are installed on both the feeding and discharging directions of the frame.

[0058] By adjusting the first electric push rod 4, the output end of the first electric push rod 4 pushes the upper fixed plate 3 to move vertically. The upper fixed plate 3 cooperates with the two groups of lower fixed plates 2 to clamp and fix the interior door panel to prevent the interior door panel from moving during the detection process.

[0059] The pressure detection probe 6 is arranged at the middle position above the upper fixing plate 3 and is used to detect the stress condition of the interior door panel.

[0060] In this embodiment, the pressure detection probe 6 is connected to an external display device to transmit the detected information in the form of numerical values ​​to the display device for user observation.

[0061] The contact surface adjustment device is arranged below the pressure detection probe 6 and is fixedly connected to the pressure detection probe 6, and is used to change the contact area between the pressure detection probe 6 and the interior door panel.

[0062] In this embodiment, a contact surface adjustment device is used to change the contact area between the pressure detection probe 6 and the interior door panel, thereby detecting different force data for different contact areas, increasing the number of tests, and making the test results more comprehensive.

[0063] like Figure 4 and Figure 5 As shown, the contact surface adjustment device includes: a second threaded rod 11, a first pressure plate 12, a threaded collar 13, multiple groups of balls 14, multiple groups of connecting rods 15, multiple groups of rotating rods 16 and multiple groups of second pressure plates 17.

[0064] Specifically, the top end of the second threaded rod 11 is fixedly connected to the bottom end of the pressure detection probe 6 .

[0066] The upper end surface of the first pressing plate 12 is fixedly connected to the bottom end of the second threaded rod 11 .

[0067] In this embodiment, the lower end surface of the first pressure plate 12 contacts the interior door panel and transmits the force in reverse to the pressure detection probe 6 .

[0068] The threaded collar 13 is threadedly connected to the outer surface of the second threaded rod 11; an annular groove is provided on the outer surface of the threaded collar 13; multiple groups of balls 14 are arranged in the annular groove and are slidably connected to the threaded collar 13 through the annular groove.

[0069] In this embodiment, when the threaded collar 13 rotates, it moves vertically along the surface of the second threaded rod 11 and is slidingly connected to the ball 14 through the annular groove, thereby driving the ball 14 to move vertically.

[0070] One end of each set of connecting rods 15 is fixedly connected to the ball 14 ; one end of each set of rotating rods 16 is rotatably connected to the connecting rod 15 .

[0073] In this embodiment, during the movement of the rotating rod 16 , the second pressing plate 17 is pulled, so that the second pressing plate 17 rotates along the connection with the first pressing plate 12 .

[0074] When the contact area needs to be adjusted, the threaded collar 13 is rotated, and the threaded collar 13 will move vertically upward along the outer surface of the second threaded rod 11; and the setting of the annular groove prevents the ball 14 from hindering the rotation of the threaded collar 13; at the same time, when the threaded collar 13 moves vertically upward, the ball 14 will drive the connecting rod 15 to move synchronously; the connecting rod 15 pulls the rotating rod 16 upward, causing the rotating rod 16 to rotate slightly while moving upward; the rotating rod 16 pulls the second pressure plate 17, causing the second pressure plate 17 to rotate upward along the connection with the first pressure plate 12; thereby, the second pressure plate 17 is no longer in contact with the interior door panel, so that the force-bearing area is reduced; different force data are detected for different contact areas, the number of tests is increased, and the test results are more comprehensive.

[0075] The contact surface adjustment device further includes: a driving assembly; the driving assembly is fixedly connected to the threaded collar 13 and is used to drive the threaded collar 13 to rotate.

[0076] like Figure 2 and Figure 3 As shown, the driving assembly includes: a spur gear 18 , a rack 19 and a second electric push rod 20 .

[0077] The spur gear 18 is sleeved on the second threaded rod 11 , and the lower end surface of the spur gear 18 is fixedly connected to the upper end surface of the threaded collar 13 .

[0078] In this embodiment, the spur gear 18 can drive the threaded collar 13 to rotate synchronously.

[0079] The rack 19 is disposed on the edge of the spur gear 18 and is meshed with the spur gear 18 ; the output end of the second electric push rod 20 is fixedly connected to the rack 19 .

[0080] In this embodiment, the model of the second electric push rod 20 is selected according to actual needs and only needs to meet the working conditions.

[0081] When the threaded collar 13 needs to be driven, the second electric push rod 20 is adjusted so that the output end of the second electric push rod 20 pushes the rack 19 to move horizontally; the rack 19 causes the spur gear 18 to rotate horizontally, and the spur gear 18 drives the threaded collar 13 to rotate at the same time.

[0082] The automobile interior door panel force detection device also includes: a position adjustment component; the position adjustment component is arranged above the pressure detection probe 6 and is fixedly connected to the pressure detection probe 6 for adjusting the position of the pressure detection probe 6.

[0083] In this embodiment, Figure 2 and Figure 6 As shown, the position adjustment assembly includes: a hydraulic cylinder 7, a moving block 8, a first threaded rod 9 and a motor 10.

[0084] Specifically, the output end of the hydraulic cylinder 7 is fixedly connected to the upper end surface of the pressure detection probe 6 .

[0085] In this embodiment, the model of the hydraulic cylinder 7 is selected according to actual needs and only needs to meet the working conditions.

[0086] The moving block 8 is arranged above the hydraulic cylinder 7 and is fixedly connected to the hydraulic cylinder 7; the first threaded rod 9 passes through the corresponding position of the moving block 8 and is threadedly connected to the moving block 8.

[0087] In this embodiment, when the first threaded rod 9 rotates, the moving block 8 moves horizontally, and the moving block 8 drives the hydraulic cylinder 7 to move at the same time.

[0088] The output end of the motor 10 is fixedly connected to one end of the first threaded rod 9 .

[0089] In this embodiment, the model of the motor 10 is selected according to actual needs and only needs to meet the working conditions.

[0090] When the position of the pressure detection probe 6 needs to be adjusted, the motor 10 is started, and the output of the motor 10 drives the first threaded rod 9 to rotate; the first threaded rod 9 causes the moving block 8 to move horizontally; the moving block 8 drives the pressure detection probe 6 to move through the hydraulic cylinder 7, and stops after moving to the position to be detected; at this time, hydraulic oil is introduced into the hydraulic cylinder 7, so that the output end of the hydraulic cylinder 7 pushes the pressure detection probe 6 to move vertically downward for detection.

[0091] The outer surface of the moving block 8 is fixedly connected to the outer surface of the second electric push rod 20, and is used to drive the second electric push rod 20 to move synchronously.

[0092] The automobile interior door panel force detection device also includes: a limiting device; the limiting device is arranged inside the hollow base and is used to limit the position of the interior door panel.

[0093] In this embodiment, Figure 7 and Figure 8 As shown, the limiting device includes: a rotating member 21, a first latch 22, a first limiting member 23, a second latch 24, a second limiting member 25 and an elastic member 26.

[0094] The first and second slideways are respectively provided at both ends of the rotating member 21 ; a first cylindrical pin is provided on the surface of the first latch 22 , the first cylindrical pin is provided in the first slideway, and is slidably connected to the rotating member 21 through the first slideway.

[0095] In this embodiment, when the rotating member 21 rotates, the first locking pin 22 moves vertically through the sliding between the first slideway and the first cylindrical pin.

[0096] The first position-limiting member 23 is disposed below the first latch 22 . The top end of the first position-limiting member 23 extends into the interior of the first latch 22 and is slidably connected to the first latch 22 .

[0097] In this embodiment, the first stopper 23 can limit the first latch 22 to move only vertically.

[0098] A second cylindrical pin is provided on the surface of the second latch 24 . The second cylindrical pin is disposed in the second slideway and is slidably connected to the rotating member 21 via the second slideway.

[0099] In this embodiment, when the second latch 24 moves vertically, the sliding between the second cylindrical pin and the second slideway causes the rotating member 21 to rotate.

[0100] The second limiting member 25 is disposed below the second bayonet 24 . The top end of the second bayonet 24 extends into the interior of the second bayonet 24 and is slidably connected to the second bayonet 24 .

[0101] In this embodiment, the second limiting member 25 can limit the second locking pin 24 to move only vertically.

[0102] The elastic member 26 is disposed between the second latch 24 and the hollow base, and is sleeved on the outer surface of the second limiting member 25 .

[0103] In this embodiment, the elastic member 26 is composed of a spring. When the interior door panel contacts the second limiting member 25, the gravity of the interior door panel itself is much greater than the elasticity of the elastic member 26, so that the second limiting member 25 moves downward and compresses the elastic member 26.

[0104] When the interior door panel moves to the second limit member 25, since the contact surface between the second limit member 25 and the interior door panel is an inclined surface, and the gravity of the interior door panel itself is much greater than the elasticity of the elastic member 26, the interior door panel will push the second limit member 25 downward when moving into the device, and compress the elastic member 26; when the second detent 24 moves vertically downward, it will slide between the second cylindrical pin and the second slideway, causing the rotating member 21 to rotate; the rotating member 21 slides between the first slideway and the first cylindrical pin, causing the first detent 22 to move vertically upward; causing the first detent 22 to exceed the upper end surface of the hollow base. Since the contact surface between the first detent 22 and the interior door panel is a vertical plane, it will not be subjected to pressure from the interior door panel, thereby blocking the incoming interior door panel; after the interior door panel contacts the first detent 22, the interior door panel just leaves the second limit member 25; the elastic member 26 will rebound and push the second limit member 25 to move upward, realizing the limitation of the interior door panel.

[0105] The vehicle interior door panel force detection device further includes: a conveyor belt 5; the conveyor belt 5 is arranged on the outer surface of one side of the housing 1 close to the second latch 24, and is used to transport the interior door panel.

[0106] Working principle:

[0107] When the automobile interior door panel force detection device is in use, the interior door panel is conveyed into the device through the conveyor belt 5. When the interior door panel contacts the second limiter 25, since the contact surface between the second limiter 25 and the interior door panel is an inclined surface, and the gravity of the interior door panel itself is much greater than the elasticity of the elastic member 26, the interior door panel pushes the second limiter 25 downward and compresses the elastic member 26 when moving into the device; when the second bayonet 24 moves vertically downward, it slides between the second cylindrical pin and the second slideway, causing the rotating member 21 to rotate. Rotation; the rotating member 21 slides between the first slide and the first cylindrical pin, so that the first pin 22 moves vertically upward; the first pin 22 exceeds the upper end surface of the hollow base. Since the contact surface between the first pin 22 and the interior door panel is a vertical plane, it will not be subjected to pressure from the interior door panel, thereby blocking the incoming interior door panel; after the interior door panel contacts the first pin 22, the interior door panel just leaves the second limiting member 25; the elastic member 26 will rebound and push the second limiting member 25 to move upward, thereby limiting the interior door panel.

[0108] Afterwards, the motor 10 is started, and the output of the motor 10 drives the first threaded rod 9 to rotate; the first threaded rod 9 causes the movable block 8 to move horizontally; the movable block 8 drives the pressure detection probe 6 to move through the hydraulic cylinder 7, and stops after moving to the position to be detected; at this time, hydraulic oil is introduced into the hydraulic cylinder 7, so that the output end of the hydraulic cylinder 7 pushes the pressure detection probe 6 to move vertically downward for detection.

[0109] When the contact area needs to be adjusted, the second electric push rod 20 is adjusted so that the output end of the second electric push rod 20 pushes the rack 19 to move horizontally; the rack 19 causes the spur gear 18 to rotate horizontally, and the spur gear 18 drives the threaded collar 13 to rotate at the same time.

[0110] At this time, the threaded collar 13 will move vertically upward along the outer surface of the second threaded rod 11; and the setting of the annular groove ensures that the ball 14 will not hinder the rotation of the threaded collar 13; at the same time, when the threaded collar 13 moves vertically upward, the ball 14 will drive the connecting rod 15 to move synchronously; the connecting rod 15 pulls the rotating rod 16 upward, causing the rotating rod 16 to rotate slightly while moving upward; the rotating rod 16 pulls the second pressure plate 17, causing the second pressure plate 17 to rotate upward along the connection with the first pressure plate 12; thereby, the second pressure plate 17 is no longer in contact with the interior door panel, reducing the area of ​​force; different force data are detected for different contact areas, the number of tests is increased, and the test results are more comprehensive, completing the use of this device.

[0111] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
