Description

Technical Field

[0001] The present invention relates to the technical field of clamping force testing devices, and in particular to a testing device for measuring the clamping force of vehicle doors. Background Art

[0002] Testing the clamping force of rail vehicle doors is very important. The clamping force test of the door is the key to ensuring the safe operation of the vehicle. When the rail train is running, the door needs to withstand a large clamping force to ensure that the door can be firmly closed, preventing passengers from accidentally opening the door during the train's travel. Excessive clamping force may cause passenger injuries, while too small clamping force may cause the door not to close firmly, affecting the normal operation of the train and the safety of passengers.

[0003] When testing the clamping force of the door, a clamping force tester is needed. During the test, hold the test main unit and the operation main unit. After debugging the test data, place the test main unit between two doors. At this time, the test rack on the test main unit is squeezed by the closing of the door, and the clamping force of the door can be measured. And sufficient data of the door clamping force can be obtained through multiple openings and closings of the door. However, in the actual test process, the position of the door may deviate due to long-term use, such as the misalignment between two doors, or the door deflects in the vertical direction. When the door is subjected to the clamping test, not only accurate and sufficient clamping force data cannot be obtained, but even the sensor on the test rack may be squeezed and damaged due to the incorrect position of the door. At the same time, since the test requires holding the test main unit and placing it at the door, and observing the data of the operation main unit at the same time, it is very easy to drop the hand during the operation, causing the test main unit to fall directly, resulting in the test rack and the sensor in the test main unit being damaged, and even directly pulling off the operation main unit, damaging the electrical components in the operation main unit.

[0031] Furthermore, in the present invention, through the arrangement of the synchronous loosening mechanism, when the test host is separated from the staff's hand and the shock-proof guard plates and the side guard plates are reset, the test host is protected as a whole. At the same time, the loosening push rod drives the loosening frame to move, and the loosening frame pushes out the plug through the two pushing frames, avoiding the problem of the test host falling and connecting with the operation host during the fall of the test host and causing damage to the operation host synchronously.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0050] Please refer to the attached specification Figures 1-11 , a test device for measuring the clamping force of a vehicle door provided by an embodiment of the present invention includes a test main unit 1, an operation main unit 3, and two connection lines 4. Plugs 5 are installed at both ends of the connection lines 4, and the two plugs 5 are respectively inserted into the test main unit 1 and the operation main unit 3. Two test frames 2 for testing are movably installed on one side of the test main unit 1, and a handle 10 is installed on the top side of the test main unit 1;

[0051] Refer to the attached specification Figures 3-7, Further, a test device for measuring the clamping force of a vehicle door provided by an embodiment of the present invention has a mounting frame 6 sleeved on a test host 1. A displacement detection mechanism 7 is installed on the mounting frame 6, and the displacement detection mechanism 7 is used to detect the position of the test vehicle door; the displacement detection mechanism 7 includes two hanging frames 701, and the two hanging frames 701 are respectively hung on the two test frames 2. Two transverse detection plates 702 are movably installed on one side of the hanging frame 701. A longitudinal detection plate 707 rotatably installed on the hanging frame 701 is provided between the two transverse detection plates 702. Two sliding frames 713 are installed on one side of the hanging frame 701, and the two sliding frames 713 are slidably installed on one side of the mounting frame 6. It should be noted that in the embodiment of the present invention, during the test, if the vehicle door undergoes lateral displacement or deflection, it will squeeze the transverse detection plate 702, or when the vehicle door undergoes vertical displacement or deflection, it cannot be in full contact with the longitudinal detection plate 707, thereby causing the longitudinal detection plate 707 to deflect, causing the test host 1 to shut down emergently, and can automatically mechanically prevent the position of the test frame 2, effectively avoiding the problem of incorrect extrusion of the test frame 2 caused by the incorrect position of the vehicle door and damage to the test host 1.

[0052] More specifically, in the present invention, an active anti-fall mechanism 8 is further installed on the mounting frame 6, and the active anti-fall mechanism 8 is used to protect the test host 1; the active anti-fall mechanism 8 includes two shock-proof plates 801, and the two shock-proof plates 801 are respectively slidably installed on the top side and the bottom side of the mounting frame 6. Side protection plates 802 are movably installed on both sides of the two shock-proof plates 801, and the two side protection plates 802 protect both sides of the test host 1. It should be noted that in the embodiment of the present invention, when the test host 1 drops off during the test, the staff's hand disengages from the handle 10. At this time, the two shock-proof plates 801 drive the two side protection plates 802 to move through a plurality of tension rods 803, so that the test frame 2 is protected by the two shock-proof plates 801 and the two side protection plates 802, avoiding direct falling and damage problems;

[0053] In this embodiment, it should be emphasized that both the shock-proof plate 801 and the side protection plate 802 are supported by rubber plates, which can not only play a shock-absorbing role, but also play a role in weight balance. When the test host 1 drops, the shock-proof plate 801 and the side protection plate 802 increase the weight of the test frame 2 and make it land first, synchronously protecting the test frame 2 and the test host 1.

[0054] Further specifically, in the present invention, a synchronous release mechanism 9 is installed on the mounting frame 6. The synchronous release mechanism 9 is used to separate the test host 1 from the plug 5. The synchronous release mechanism 9 includes a release frame 901 which is movably installed on the mounting frame 6. Two push frames 905 are installed on the release frame 901. The push frames 905 are in contact with the two plugs 5. The movement of the release frame 901 is used to synchronously push out the two plugs 5. It should be noted that in the embodiment of the present invention, when the test host 1 is separated from the operator's hand and the shock-proof guard plate 801 and the side guard plate 802 are reset, the test host 1 is integrally protected. At the same time, the release push rod 902 drives the release frame 901 to move, and the release frame 901 pushes out the plug 5 through the two push frames 905, avoiding the connection with the operation host 3 when the test host 1 falls, resulting in the problem of synchronous dropping and damage of the operation host 3.

[0055] Refer to the attached drawings of the specification Figures 3-7 Furthermore, in the test device for measuring the clamping force of a car door provided by the embodiment of the present invention, the displacement detection mechanism 7 further includes four locking rack frames 709. The two locking rack frames 709 on the same side are respectively slidably installed on a hanging rack 701. Four positioning racks 714 are installed on one side of the mounting frame 6. The locking rack frames 709 are engaged with the positioning racks 714 for locking the hanging rack 701.

[0056] A contraction spring 710 is installed on one side of the locking rack frame 709, and the other end of the contraction spring 710 is installed on the inner wall of one side of the hanging rack 701.

[0057] And an emergency stop switch 719 is installed on the inner wall of the hanging rack 701. The movement of the locking rack frame 709 is used to trigger the emergency stop switch 719. It should be noted that in the embodiment of the present invention, when the car door undergoes lateral displacement or deflection, the locking rack frame 709 is released from the limitation. Then, under the pulling force of the contraction spring 710, it moves and triggers the emergency stop switch 719, causing the test host 1 to shut down emergently. At the same time, the locking rack frame 709 engages with the positioning rack 714 to mechanically prevent the position of the test frame 2.

[0058] Refer to the attached drawings of the specification Figures 3-7 Further specifically, in the embodiment of the present invention, two limiting sliding frames 703 are installed on each of the two lateral detection plates 702 located on the same hanging rack 701. Two push frames 708 are slidably installed on the hanging rack 701. The two push frames 708 are used to support the longitudinal detection plate 707.

[0059] On one side of the pushing frame 708, a releasing frame 704 is installed. On one side of the releasing frame 704, two arc-shaped seats 705 are installed, and the two arc-shaped seats 705 are in contact with the two limiting sliding frames 703. It should be noted that in the embodiment of the present invention, when the lateral detection plate 702 moves horizontally and drives the limiting sliding frame 703 to move, the limiting sliding frame 703 squeezes the arc-shaped seat 705, thereby driving the releasing frame 704 to move. When the longitudinal detection plate 707 deflects, it rotates on the support seat 718 through the mounting seat 717, thereby driving the pushing frame 708 to move, and similarly, the pushing frame 708 drives the releasing frame 704 to move.

[0060] Refer to the attached drawings of the specification Figures 3-7 Furthermore, specifically, in the embodiment of the present invention, a pulling spring 706 is installed on one side of the releasing frame 704, and the other end of the pulling spring 706 is installed on the hanging frame 701;

[0061] A locking frame 711 is installed on one side of the releasing frame 704. A locking slot 712 is formed on the locking rack frame 709, and one side of the locking frame 711 is inserted into the locking slot 712 for locking the locking rack frame 709. It should be noted that in the embodiment of the present invention, when two vehicle doors are respectively inserted on the two hanging frames 701, if the vehicle doors undergo lateral displacement or deflection, they will squeeze the lateral detection plate 702 to move horizontally and drive the limiting sliding frame 703 to move. The limiting sliding frame 703 squeezes the arc-shaped seat 705 and then drives the releasing frame 704 to move. Or when the vehicle doors undergo vertical displacement or deflection and cannot fully contact the longitudinal detection plate 707, the longitudinal detection plate 707 will deflect. The longitudinal detection plate 707 rotates on the support seat 718 through the mounting seat 717, thereby driving the pushing frame 708 to move. The movement of the pushing frame 708 drives the releasing frame 704 to move, thereby driving the pulling spring 706 to move. At the same time, the movement of the releasing frame 704 drives the locking frame 711 to disengage from the locking slot 712, so that the locking rack frame 709 is released from the limitation, and then it moves under the pulling force of the contraction spring 710 and triggers the emergency stop switch 719, causing the test host 1 to shut down emergently. At the same time, the locking rack frame 709 engages with the positioning rack 714 to mechanically block the position of the test frame 2.

[0062] Refer to the attached drawings of the specification Figures 3-7 Furthermore, specifically, in the embodiment of the present invention, two cross-moving frames 715 are installed on each of the two lateral detection plates 702. The two cross-moving frames 715 on the same side are slidably installed on one side of the hanging frame 701. A return spring 716 is installed on one side of the cross-moving frame 715, and the other end of the return spring 716 is installed on the inner wall of one side of the hanging frame 701;

[0063] A support base 718 installed on one side of the hanging mount 701 is provided between two lateral detection plates 702. A mounting base 717 is installed on one side of the longitudinal detection plate 707, and the mounting base 717 is rotatably installed on the support base 718. It should be noted that in the embodiment of the present invention, when the lateral detection plate 702 moves, it horizontally moves on one side of the hanging mount 701 through two transverse moving frames 715, and drives the return spring 716, so as to realize the horizontal transverse movement of the lateral detection plate 702. At the same time, when the longitudinal detection plate 707 rotates, it rotates on the support base 718 through the mounting base 717.

[0064] Refer to the attached drawings of the specification Figures 8-10 Furthermore, in the embodiment of the present invention, a test device for measuring the clamping force of a car door, the active anti-fall mechanism 8 further includes a rotating push rod 805. The rotating push rod 805 is rotatably installed on the top side of the test main body 1. The shock-proof guard plate 801 is movably installed on the rotating push rod 805. A push-pull frame 808 is slidably installed on the handle 10, and a linkage plate 809 is movably installed between the push-pull frames 808;

[0065] Two tension rods 803 are respectively movably installed on both sides of the shock-proof guard plate 801. The two tension rods 803 on the same side are installed on a side guard plate 802. Two buffer springs 804 are installed on one side of the shock-proof guard plate 801, and the other ends of the two buffer springs 804 are installed on the side guard plate 802. It should be noted that in the embodiment of the present invention, during the process of the shock-proof guard plate 801 driving the two side guard plates 802 to move, if the position of the test frame 2 exceeds the position of the test main body 1, causing the side guard plate 802 to be extruded and pulled out when it extends, so that the side guard plate 802 moves outward on one side of the shock-proof guard plate 801 through the tension rod 803, and drives the buffer spring 804 to be stressed, which can effectively protect the test frame 2.

[0066] Refer to the attached drawings of the specification Figures 8-10 Furthermore, specifically in the embodiment of the present invention, two transfer shafts 806 are rotatably installed on the rotating push rod 805. One transfer shaft 806 is installed on the top side of the test main body 1. A driving groove 807 is formed on the shock-proof guard plate 801, and the other corresponding transfer shaft 806 is movably installed in the driving groove 807;

[0067] Two linkage shafts 810 are rotatably installed on the linkage plate 809, and the two linkage shafts 810 are respectively installed on the rotating push rod 805 and the push-pull frame 808. It should be noted that in the embodiment of the present invention, when using the test host 1, put the hand into the handle 10 and synchronously drive the push-pull frame 808 to move. The push-pull frame 808 drives the linkage plate 809 to move through a linkage shaft 810, and the linkage plate 809 drives the rotating push rod 805 to rotate through another linkage shaft 810. The rotating push rod 805 rotates on a transfer shaft 806, and the rotating push rod 805 drives the shock-proof guard plate 801 to move through another transfer shaft 806, so as to achieve the purpose of automatically retracting the shock-proof guard plate 801 when using the test host 1.

[0068] Refer to the attached drawings of the specification Figures 8-10 Specifically, in the embodiment of the present invention, a limiting frame 811 is installed on the bottom side of the installation frame 6, a limiting block 812 is slidably installed in the limiting frame 811, and the limiting block 812 is installed on a shock-proof guard plate 801 located below the test host 1;

[0069] A retraction spring 813 is installed on one side of the limiting block 812, and the other end of the retraction spring 813 is installed on the inner wall of the limiting frame 811. It should be noted that in the embodiment of the present invention, when the test host 1 drops off accidentally, no force is applied to the push-pull frame 808. At this time, under the pulling force of the retraction spring 813, the limiting block 812 moves horizontally in the limiting frame 811, thereby driving the two shock-proof guard plates 801 to drive the two side guard plates 802 to move, so as to wrap the test host 1 and the test rack 2 to prevent the test host 1 from being damaged when it drops.

[0070] Refer to the attached drawings of the specification Figure 8 and Figure 11 Specifically, in the embodiment of the present invention, the synchronous release mechanism 9 further includes a release push rod 902. A push-out hole 904 is formed in the limiting frame 811, and the release push rod 902 is movably installed in the push-out hole 904;

[0071] One end of the release push rod 902 is installed on the release frame 901, and a magnetic attraction plate 903 is installed at the other end of the release push rod 902. The magnetic attraction plate 903 is attracted to the limiting block 812. It should be noted that in the embodiment of the present invention, when the test host 1 drops off accidentally, the limiting block 812 is separated from the magnetic attraction plate 903, thereby driving the release push rod 902 to move, so that the release frame 901 pushes the plug 5 out of the test host 1 through the two push-out frames 905, preventing the test host 1 from pulling the test rack 2 to drop when it drops through the connecting wire 4.

[0072] Refer to the attached drawings of the specification Figure 8 and Figure 11, Further specifically, in the embodiment of the present invention, a release spring 906 is installed on one side of the magnetic attraction plate 903, and the other end of the release spring 906 is installed on the inner wall of the limiting frame 811. It should be noted that in the embodiment of the present invention, when the limiting block 812 disengages from the magnetic attraction plate 903, under the resilience of the release spring 906, it can drive the release push rod 902 to move, and then drive the two push-out frames 905 to move through the release frame 901, so as to push the plug 5 out of the test host 1.

[0073] In summary, the working principle of a test device for measuring the clamping force of a car door provided by the embodiment of the present invention is as follows:

[0074] When using the test host 1 for testing, the staff's hand reaches into the handle 10 and drives the push-pull frame 808 to move. The push-pull frame 808 drives the linkage plate 809 to move through a linkage shaft 810. The linkage plate 809 pulls the rotating push rod 805 to rotate through another linkage shaft 810. The rotating push rod 805 rotates on a transfer shaft 806. At the same time, the rotating push rod 805 drives the shock-proof guard plate 801 to move through another transfer shaft 806. At the same time, the transfer shaft 806 slides in the driving groove 807. At the same time, the shock-proof guard plate 801 drives the two side guard plates 802 to move through a plurality of stretching rods 803. At the same time, the two side guard plates 802 drive another shock-proof guard plate 801 to move, so that the shock-proof guard plate 801 located below the test host 1 horizontally slides in the limiting frame 811 through the limiting block 812, and drives the retraction spring 813 to be stressed, so that the test frame 2 is exposed for testing;

[0075] During the test, the two car doors are respectively inserted on the two hanging racks 701. At this time, if the car doors have lateral displacement or deflection, they will squeeze the lateral detection plate 702. The lateral detection plate 702 transversely moves on the hanging rack 701 through the transverse movement frame 715, and at the same time drives the limiting sliding frame 703 to move. The limiting sliding frame 703 squeezes the arc seat 705 and then drives the release frame 704 to move. Or when the car doors have vertical displacement or deflection and cannot be completely in contact with the longitudinal detection plate 707, the longitudinal detection plate 707 will deflect. The longitudinal detection plate 707 rotates on the support seat 718 through the mounting seat 717, and then drives the push frame 708 to move. The push frame 708 moves to drive the release frame 704 to move, and then drives the pull-back spring 706 to move. At the same time, the release frame 704 moves to drive the locking frame 711 to disengage from the locking slot 712, so that the locking rack frame 709 is released from the limitation, and then moves under the pulling force of the contraction spring 710 and triggers the emergency stop switch 719, so that the test host 1 shuts down emergently. At the same time, the locking rack frame 709 engages with the positioning rack 714 to mechanically block the position of the test frame 2, which can effectively avoid the problem of incorrect extrusion of the test frame 2 caused by the incorrect position of the car door and damage to the test host 1;

[0076] When the operator operates improperly and causes the test host 1 to break away from the operator's hand, under the tensile force of the retraction spring 813, the limiting block 812 is reset, and then the shock-proof guard plate 801 and the side guard plate 802 are reset, so as to protect the test host 1 as a whole and prevent the test host 1 from being damaged due to falling. At the same time, when the limiting block 812 moves and breaks away from the magnetic attraction plate 903, under the resilience of the release spring 906, the magnetic attraction plate 903 returns to its original position and drives the release push rod 902 to move, so that the release push rod 902 drives the release frame 901 to move, and the two plugs 5 are pushed out through the two push-out frames 905, avoiding the connection between the test host 1 and the operation host 3 when the test host 1 falls and causing the synchronous drop and damage of the operation host 3.

[0077] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
