Description

Technical Field

[0001] The invention relates to the technical field of automobile seat pressure resistance testing, in particular to an automobile seat compression resistance testing mechanism. Background Art

[0002] Car seats can be divided into split seats and long seats according to their shapes; they can be divided into fixed, detachable and adjustable types according to their functions; they can be divided into single, double and multi-person seats according to the number of passengers. According to the performance of the seats, they have developed from the earliest fixed seats to multi-functional power-adjustable seats, including air cushion seats, electric seats, stereo seats, mental recovery seats, and electronically adjustable seats. According to the material, they can be divided into leather seats and velvet seats, etc. There are also some seats for special users, such as child seats and racing seats.

[0003] The testing items of car seats mainly include durability test, functional test, comfort evaluation, material and environmental test, size and assembly measurement, strength and compliance test. The compression resistance test of car seats is a part of the durability test.

[0004] Patent document with publication number CN219675436U A car seat compression resistance test mechanism is operated by a cylinder to move a pressure plate downward, and the downward pressure plate contacts and squeezes the car seat placed on a storage dish or a turntable, and obtains pressure through a pressure sensor to achieve the purpose of testing the car seat;

[0005] At the same time, through the rotation of the screw rod, the screw rod and the pressure plate are threadedly transmitted, so that the screw rod is displaced along the vertical direction of the pressure plate, and the displaced screw rod drives the fixedly connected disc-shaped pressure piece to move downward, and the downwardly displaced pressure piece protrudes from the end wall of the pressure plate. At this time, the smaller pressure piece can contact a small area on the car seat. Compared with the large-volume piece, there will be a gap when contacting with the concave arc-shaped end wall of the car, and the contact is not tight enough. The smaller pressure piece can test the car seat more accurately, and when the pressure piece moves downward with the pressure plate, the extrusion resistance of small areas and nodes of the car seat can be tested.

[0006] In addition to testing the anti-extrusion properties of various joints of the seat, the car seat compression resistance test mechanism can also perform compression resistance tests on various area points. It has comprehensive functions. Referring to the actual usage scenarios of car seats, the seat cushion and backrest parts of the seat are often suddenly impacted. The existing test structures all use slow pressure to make the test components act on the seat to perform compression resistance testing. It is difficult to truly simulate the working environment of the seat and there are still certain limitations. Summary of the invention

[0007] In order to overcome the problem that the existing automobile seat compression resistance testing mechanisms all use a method of slowly applying pressure to make the test components act on the seat to perform compression resistance testing, which makes it difficult to truly simulate the working environment of the seat and still has certain limitations, the embodiment of the present application provides an automobile seat compression resistance testing mechanism, which controls the horizontal plate through a first pneumatic telescopic rod to drive the erection rod to slide toward the top inside the positioning column sleeve, so that the gravity simulation structure is extended to a fixed height under the support of the two columns at one end of the two erection rods. When the movable end of the first pneumatic telescopic rod is quickly retracted into the fixed end, the gravity simulation structure naturally applies pressure to the bottom of the automobile seat, thereby simulating the action of a user sitting on the top of one side of the automobile seat, and completing the corresponding testing work;

[0008] At the same time, by utilizing the second pneumatic telescopic rod to control the knocking arm to rotate around the hinge point between the knocking arm and the supporting frame, the tension spring between the knocking arm and the supporting frame can be stretched. The tension spring can be reset with the help of the second pneumatic telescopic rod when it is instantly reset, so that the knocking simulation structure knocks on the backrest part of the car seat, thereby simulating the action of the user's back leaning back when sitting down, so as to complete the test work in the corresponding usage scenario.

[0036] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0037] Embodiment 1:

[0038] This embodiment introduces a specific structure of a vehicle seat compression resistance test mechanism. Figure 1-Figure 8 As shown, it includes a gravity simulation structure and a test bracket 6, the gravity simulation structure includes a first support rod 24, the first support rod 24 is sleeved with a first test tube 23 on the outside, the first test tube 23 is interference-fitted with a first protective rubber sleeve 2 on the outside, both ends of the first support rod 24 are provided with a mounting rod 12, the surface of the middle part of the mounting rod 12 is processed with a horizontal plate 11, and the bottom of one end of the horizontal plate 11 is provided with a first pneumatic telescopic rod 7;

[0039] Wherein, both sides of the test bracket 6 are provided with support bases 8. When the compression resistance side view of the car seat 1 is performed, the car seat 1 is first assembled and fixed on the top of the test bracket 6, so that the two gravity simulation structures (located at the top of the center and one side of the car seat 1, respectively) are both located at the top of the car seat 1. When the two first pneumatic telescopic rods 7 are respectively assembled to the bottom of the two support bases 8, and the gravity simulation structure is lifted to a certain height by using the cross plate 11 and the erection rod 12, the movable end of the first pneumatic telescopic rod 7 (whose movable speed can be adjusted according to the prior art) is quickly retracted into the interior of the fixed end, so that the gravity simulation structure naturally applies pressure to the car seat 1 from the bottom, so that the test result can be obtained through the performance state of the car seat 1 after the pressure is applied;

[0040] Secondly, in order to facilitate fixing the support frame 8 to one side of the test frame 6, when the car seat 1 is assembled to the top of the test frame 6, the gravity simulation structure mounted on the top of the two support frames 8 can simulate the gravity pressure state, such as Figure 5 As shown, a plurality of plug blocks 21 are welded to one side of the bottom of the two support base frames 8. By inserting the plurality of plug blocks 21 into the interior of the test bracket 6, after the support base frames 8 and the test bracket 6 are assembled and fixed by bolts, the two support base frames 8 with the gravity simulation structure on the top can be fixed to the two sides of the test bracket 6;

[0041] Furthermore, in order to install the first support rod 24 between the two erection rods 12 and control the trajectory of the erection rods 12 moving up and down, as shown in FIG. Figure 5 As shown, two positioning column sleeves 18 are processed on the top of one end of the two supporting base frames 8, a column 9 is processed on one end of the erection rod 12, and a positioning circular groove 22 is processed on one side of the column 9. By making the two ends of the first support rod 24 respectively located in the positioning circular grooves 22 of the columns 9 at the top of the two supporting base frames 8, the erection rods 12 at both ends of the first support rod 24 can be slidably connected to the inside of the positioning column sleeves 18 on the top of the two supporting base frames 8, which not only limits the two ends of the first support rod 24 from being disconnected from the two columns 9, but also allows the first support rod 24 to drive the two erection rods 12 to be inside the two positioning column sleeves 18 on the supporting base frames 8.

[0042] Embodiment 2:

[0043] Based on Example 1, this example introduces a knock simulation structure of a car seat compression resistance test mechanism, such as Figures 1 to 4 , Figure 7 As shown, the knocking simulation structure includes a second support rod 28, the second support rod 28 is sleeved with a second test tube 27, the second test tube 27 is interference-fitted with a second protective rubber sleeve 5, and both ends of the second support rod 28 are provided with a knocking arm 17, one side of one end of the knocking arm 17 is provided with a tension spring 13, and the other side of one end of the knocking arm 17 is provided with a second pneumatic telescopic rod 10;

[0044] Among them, the knocking simulation structure is arranged on one side of the gravity simulation structure, and the test bracket 6 is arranged at the bottom of the gravity simulation structure and the knocking simulation structure. Before the gravity simulation structure applies pressure to the car seat 1 from the top to the bottom, the second pneumatic telescopic rod 10 first controls the knocking arm 17 to rotate around the hinge point between it and the supporting base frame 8, so as to stretch the tension spring 13 between the knocking arm 17 and the supporting base frame 8. The first pneumatic telescopic rod 7 controls the gravity simulation structure to move to the top through the erection rod 12 and the cross plate 11, and applies pressure to the bottom. When simulating the action of human body sitting down, the second pneumatic telescopic rod 10 can be instantly extended to reset the tension spring 13 and drive the knocking arm 17 to reset, so that the knocking simulation structure knocks the backrest part of the car seat 1 to simulate the action of the back leaning back in time when the user sits down;

[0045] Secondly, the two ends of the second pneumatic telescopic rod 10 are respectively hinged to the top of the center of the support frame 8 and the other side surface of one end of the knocking arm 17, and one end of the knocking arm 17 is hinged to the center of the top of the support frame 8. In order to connect the tension spring 13 between the knocking arm 17 and one end of the support frame 8, as shown in FIG. Figure 3 As shown, a second hook 20 is processed on the top of one end of the supporting frame 8, and a first hook 19 is processed on the surface of one side of one end of the knocking arm 17. By making the two ends of the tension spring 13 respectively hooked on the outside of the first hook 19 and the second hook 20, when the second pneumatic telescopic rod 10 pulls one end of the knocking arm 17, the knocking arm 17 can be rotated around the intersection with the supporting frame 8, thereby stretching the tension spring 13 to store force for it.

[0046] Embodiment 3:

[0047] Example 1 and Figure 2 Based on this, this embodiment introduces the specific structures of the knocking simulation structure and the gravity simulation structure, such as Figures 6 to 8 As shown, a plurality of column receiving grooves 14 are processed inside both ends of the first test tube 23 and the second test tube 27, and a counterweight block 15 is arranged inside the plurality of column receiving grooves 14.

[0048] The counterweight block 15 includes a pull ring 152, one end of which is welded to a counterweight column 151. By holding the counterweight column 151, the pull ring 152 is controlled to be inserted into the storage column slot 14 on the first test cylinder 23, or inserted into the storage column slot 14 on the second test cylinder 27, so that the overall weight of the second test cylinder 27 or the first test cylinder 23 can be adjusted, so as to facilitate adjusting the weight of the gravity simulation structure and the knocking simulation structure according to the target population.

[0049] Secondly, in order to facilitate the installation of the counterweight block 15 into the interior of the storage column slot 14 from one end of the first test cylinder 23 or the second test cylinder 27, and to prevent the counterweight block 15 from sliding out of the interior of the storage column slot 14 according to the situation, Figure 6 and Figure 8As shown, the outer ends of the first support rod 24 and the second support rod 28 are both sleeve-connected with the limit plate 16, and a plurality of through-slot openings 25 are processed inside the limit plate 16. A control button 26 is processed on the surface of one side of the limit plate 16. By making the plurality of through-slot openings 25 communicate with the interior of the plurality of storage column grooves 14 at one end of the second test cylinder 27 or the first test cylinder 23, respectively, when the control limit plate 16 is rotated, the through-slot openings 25 on the limit plate 16 can be adjusted to be aligned with or out of position with the storage column groove 14, so as to support the counterweight block 15 to be stored inside the storage column groove 14, or to install the counterweight block 15;

[0050] Furthermore, in order to install the first test tube 23 at the center of the first support rod 24, and install the second test tube 27 at the center of the second support rod 28, as shown in FIG. Figures 6 to 8 As shown, the first two ends of the first support rod 24 are both sleeve-connected with the first gasket 3, and the second two ends of the second support rod 28 are both sleeve-connected with the second gasket 4. By supporting the first gasket 3 between the limit plate 16 and the column 9, the limit plate 16 is pressed on the surface of one end of the first protective rubber sleeve 2, so that the position of the first test cylinder 23 outside the first support rod 24 can be controlled, and the friction between the limit plate 16 and the first protective rubber sleeve 2 is used to limit the limit plate 16 from rotating outside the first support rod 24, so that the slotting opening 25 is misaligned with the storage column slot 14, and the counterweight block 15 is stored in the storage column slot 14.

[0051] At the same time, by supporting the second gasket 4 between the limit plate 16 and the knocking arm 17, the position of the second test cylinder 27 outside the second support rod 28 can be controlled, and the limit plate 16 can be pressed against the surface of one end of the second protective rubber sleeve 5. The friction between the limit plate 16 and the second protective rubber sleeve 5 can be used to limit the rotation of the limit plate 16 outside the first support rod 24, so that the slotting opening 25 is misaligned with the storage column slot 14, and the counterweight block 15 is stored in the inside of the storage column slot 14.

[0052] Specifically, when the automobile seat compression resistance testing device is used to test the automobile seat 1:

[0053] First, the first pneumatic telescopic rod 7 is started, so that the fixed end of the first pneumatic telescopic rod 7 is supported by the support base 8, and the horizontal plate 11 is controlled to drive the erection rod 12 to slide toward the top inside the positioning column sleeve 18, thereby driving the first support rod 24 to move toward the top under the support of the two columns 9 at one end of the two erection rods 12, thereby driving the gravity simulation structure to extend to a fixed height;

[0054] Then, the second pneumatic telescopic rod 10 is started to control the knocking arm 17 to rotate around the hinge point between the knocking arm 17 and the supporting chassis 8, and the tension spring 13 between the knocking arm 17 and the supporting chassis 8 is stretched, and the two knocking arms 17 are used to drive the knocking simulation structure to bypass the two gravity simulation structures, so that the application remains in the state before the test;

[0055] Next, the car seat 1 is assembled and fixed on the top of the test bracket 6, and the first pneumatic telescopic rod 7 is first controlled to quickly retract its movable end into the fixed end, so that the gravity simulation structure naturally applies pressure to the car seat 1 from the bottom (in this process, the first protective rubber sleeve 2 is sleeved on the outside of the first test tube 23, and when the gravity simulation structure as a whole hammers the car seat 1 from the bottom, the first protective rubber sleeve 2 can be used to complete the buffering protection work), so that the test result can be obtained through the performance state of the car seat 1 after the pressure is applied;

[0056] At the same time, the second pneumatic telescopic rod 10 is started to make its movable end instantly extend from the inside of the fixed end, and the stretched tension spring 13 is used to store force and reset, so that the knocking simulation structure knocks the backrest part of the car seat 1 (in this process, the second protective rubber sleeve 5 is sleeved to the outside of the second test cylinder 27. When the two knocking arms 17 drive the second support rod 28 to move, the second test cylinder 27 can knock the backrest part of the car seat 1, and the buffer protection work is completed by the second test cylinder 27). It can simulate the action of the back leaning back when the user sits down, so as to obtain the test result through the state of the car seat 1 in the knocking state;

[0057] It is worth noting that the overall weight of the gravity simulation structure and the knock simulation structure can be adjusted according to the target population by installing a counterweight block 15 inside the storage column slot 14 on the second support rod 28 and the first test cylinder 23, which is simple and convenient.

[0058] At the same time, by sleeve-fitting the limit plate 16 on both ends of the first test tube 23 and the second support rod 28, and according to the connection and eccentricity of the slotted opening 25 on the limit plate 16 and the storage column slot 14, the counterweight block 15 is supported to be stored inside the storage column slot 14 and the counterweight block 15 is installed in the storage column slot 14 or taken out from the storage column slot 14.

[0059] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
