Description

Technical Field

[0001] The invention relates to the technical field of automobile detection, in particular to a seat strength testing device. Background Art

[0002] Automobile inspection is to determine the technical condition or working ability of the automobile. During the use of the automobile, as the use time increases (or the mileage increases), its parts gradually wear, corrode, deform, age, and the lubricant deteriorates, causing the clearance of the fitting to increase, causing loose movement, vibration, noise, and air, water, oil leakage, etc., resulting in a decline in the technical performance of the automobile.

[0003] As one of the essential structural components of a car, the car seat is the main direct carrier of the human body in the vehicle, which directly determines the comfort of the user to a large extent. During long-term use, its structural strength will decrease, affecting the driving and riding safety. Therefore, it is necessary to conduct strength testing on it.

[0004] A multifunctional testing device for bus seat strength testing with publication number CN209459848U can meet the strength test of bus seat seat panels and back panels by arranging vertical force-applying components and horizontal force-applying components on the same test bench. The utility model can also be used for strength test of seat back armrests and vehicle fixings of seats. It integrates multiple testing functions in one, replacing the original multiple testing devices and reducing equipment investment and land investment in seat testing.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] The existing multifunctional test device for seat strength test uses vertical force and horizontal force to test the strength of bus seats and backboards. However, this method applies independent pressure to the seat and backboard, which is not convenient for performing the overall strength test at one time when testing the strength of the backboard and seat, and is inefficient. Summary of the invention

[0007] In order to overcome the shortcomings of independent pressure application on the seat and back panel of the existing multifunctional test device for seat strength test, which makes it inconvenient to perform the overall strength test at one time when performing the strength test of the back panel and the seat, and the low efficiency, an embodiment of the present application provides a seat strength testing device, which places the seat to be tested between two pressure members, and controls the pressure rod between the two positioning rings to move closer to the seat by two second hydraulic push rods working simultaneously, thereby fixing the seat. The back panel support arm and the seat support arm can be pulled to fold from the edge to the center by controlling the two first hydraulic push rods with pressure sensors themselves, so as to apply pressure to the seat and the back panel, thereby facilitating a one-time seat strength test with high efficiency.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0009] A seat strength testing device comprises a testing structure and a clamping structure, wherein the clamping structure is arranged at the top of the center of the testing structure;

[0011] In one possible implementation, the test structure includes two connecting plates, the tops of one ends of the two connecting plates are hingedly connected to seat support arms, the tops of the other ends of the two connecting plates are hingedly connected to back panel support arms, pressure pieces are provided between the two seat support arms and the two back panel support arms, and the same first hydraulic push rod is hingedly connected between the middle parts of the seat support arms and the back panel support arms.

[0012] In one possible implementation, the pressure member includes a cushion block, support rods are integrally formed on both sides of the bottom of the cushion block, a rubber plate is adhesively connected to the top surface of the cushion block, both ends of the support rod are respectively inserted into two seat support arms or two back support arms, and the support rod is limited from being disconnected from the seat support arms or the back support arms by a threaded connection nut.

[0013] In a possible implementation, the top of the cushion block is raised from the surface of the seat support arm or the back support arm, so that the rubber plate between the two seat support arms is supported on the bottom of the seat, and the rubber plate between the two back support arms is supported on the back of the backboard.

[0015] In a possible implementation, a threaded rod is processed on the outer wall of the positioning ring, and the threaded rod is threadedly connected to the inside of one end of the second hydraulic push rod to support the adjustment of the length of the positioning ring and one end of the second hydraulic push rod.

[0016] In a possible implementation manner, one end of the pressure rod is processed into a rounded corner, and the other end of the pressure rod is processed with a control ring.

[0017] In a possible implementation, one end of the two seat support arms and one end of the two backboard support arms are processed with a slide groove, and one end of the two support rods are slidably connected inside the slide groove.

[0029] 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:

[0030] Embodiment 1:

[0031] This embodiment introduces a specific structure of a seat strength testing device. Figure 1-Figure 5 As shown, it includes a test structure 4 and a clamping structure 5 arranged at the top of the center of the test structure 4, the bottoms of the two connecting plates 404 are assembled and connected to the same erection base plate 3, the four corners at the bottom of the erection base plate 3 are assembled and connected to the columns 1, and the bottoms of the four columns 1 are assembled and connected to the support base plate 2;

[0032] like Figure 2 and Figure 3 As shown, the test structure 4 includes two connecting plates 404, the tops of one ends of the two connecting plates 404 are hingedly connected to the seat support arms 401, the tops of the other ends of the two connecting plates 404 are hingedly connected to the back plate support arms 403, a pressure member 402 is provided between the two seat support arms 401 and the two back plate support arms 403, and the same first hydraulic push rod 405 is hingedly connected between the middle parts of the seat support arms 401 and the back plate support arms 403;

[0033] In order to enable the two seat support arms 401 and the two back support arms 403 to set up the seat, Figure 4 As shown, the pressure member 402 includes a cushion block 4023, and support rods 4021 are integrally formed at both sides of the bottom of the cushion block 4023. By inserting the two ends of the support rod 4021 into the two seat support arms 401 or the two back support arms 403, and limiting the support rod 4021 from being disconnected from the seat support arms 401 or the back support arms 403 by threaded connection nuts, the two pressure members 402 can be respectively connected between the two seat support arms 401 and the back support arms 403, so that the seat is placed between the two pressure members 402.

[0034] Secondly, in order to prevent the pressure member 402 from damaging the surface of the seat when the seat support arm 401 and one end of the back support arm 403 are close to each other, such as Figure 4As shown, the top surface of the cushion block 4023 is connected with a rubber plate 4022 by adhesive bonding. By making the top of the cushion block 4023 protrude from the surface of the seat support arm 401 or the back support arm 403, the rubber plate 4022 between the two seat support arms 401 can be supported on the bottom of the seat, and the rubber plate 4022 between the two back support arms 403 can be supported on the back of the back plate, forming protection;

[0035] like Figure 5 As shown, the clamping structure 5 includes two second hydraulic push rods 503, and the other ends of the two second hydraulic push rods 503 are provided with positioning rings 502, and the same pressure rod 501 is movably connected between the two positioning rings 502;

[0036] Among them, one end of the two second hydraulic push rods 503 is respectively hingedly connected to the top of one side of the two connecting plates 404. By processing one end of the pressure rod 501 into a rounded corner and processing a control ring 504 on the other end of the pressure rod 501, when the pressure rod 501 passes through the two positioning rings 502, the two second hydraulic push rods 503 can work simultaneously to pull the pressure rod 501 to the connection point between the seat and the backboard, so as to fix the seat between the two pressure members 402;

[0037] At the same time, in order to adjust the distance between the positioning ring 502 and one end of the second hydraulic push rod 503, the position between the pressure rod 501 and the seat is adjusted, such as Figure 2 and Figure 5 As shown, the outer wall of the positioning ring 502 is processed with a threaded rod, which is threadedly connected to the inside of one end of the second hydraulic push rod 503, supporting the adjustment of the length of the positioning ring 502 and one end of the second hydraulic push rod 503, so that when the seat is placed between the two pressure members 402, the pressure rod 501 can pass through the inside of the two positioning rings 502 and be located on the top of the seat.

[0038] By adopting the above technical solution:

[0039] The above-mentioned design places the seat to be tested between two pressure pieces 402, so that the pressure piece 402 between the two seat support arms 401 is supported on the bottom of the seat, and the pressure piece 402 between the two backboard support arms 403 is supported on the back of the backboard. The pressure rod 501 can be passed through the inside of the two positioning rings 502 so that the pressure rod 501 is located above the seat. When the two second hydraulic push rods 503 work simultaneously, the pressure rod 501 is pulled toward the connection point between the seat and the backboard, so that the seat is fixed between the two pressure pieces 402. Then, by controlling the two first hydraulic push rods 405 with their own pressure sensors, the backboard support arm 403 and the seat support arm 401 can be folded from the edge to the center to apply pressure to the seat and the backboard, thereby facilitating the one-time seat strength testing work with high efficiency.

[0040] Embodiment 2:

[0041] Based on Example 1, this example introduces the specific structure of the test structure 4, where one end of the two seat support arms 401 and one end of the two back support arms 403 are processed with a slide groove 6;

[0042] Among them, by making one end of the two support rods 4021 slidably connected to the inside of the slide groove 6, the position of the pressure member 402 between the two seat support arms 401 or the two back support arms 403 can be adjusted, thereby controlling the force application points of the two pressure members 402 on the seat bottom and the back plate to perform strength tests at different positions;

[0043] Secondly, in order to prevent the pressure member 402 from sliding between the two seat support arms 401 or the two back support arms 403, as shown in FIG. Figure 4 As shown, one end of the two seat support arms 401 and one end of the two back panel support arms 403 are processed with multiple positioning grooves 7, and each positioning groove 7 is connected with the corresponding slide groove 6 on the seat support arm 401 or the back panel support arm 403. When one end of the two support rods 4021 slides from the inside of the slide groove 6 to the inside of the two positioning grooves 7, the pressure member 402 can be set between the target positions of the two seat support arms 401 or the two back panel support arms 403.

[0044] By adopting the above technical solution:

[0045] The above-mentioned design processes a slide groove 6 at one end of the two seat support arms 401 and one end of the two back panel support arms 403, and processes a plurality of positioning notches 7 at one end of the two seat support arms 401 and one end of the two back panel support arms 403, so that the slide groove 6 on the corresponding seat support arm 401 or the back panel support arm 403 is connected with the plurality of positioning notches 7. When one end of the two support rods 4021 slides from the inside of the slide groove 6 to the inside of the two positioning notches 7, the pressure piece 402 can be set between the target positions of the two seat support arms 401 or the two back panel support arms 403, so that the rubber plate 4022 on the top of the pressure piece 402 is accurately supported on the bottom of the seat or the back of the back panel.

[0046] Specifically, when using the seat strength testing device to work:

[0047] First, after controlling one end of the two support rods 4021 to slide from the inside of the slide slot 6 to the inside of the two positioning notches 7, the pressure member 402 is set between the target positions of the two seat support arms 401 or the two back support arms 403;

[0048] Then, the seat to be tested is placed between the two pressure pieces 402, so that the pressure piece 402 between the two seat support arms 401 is supported on the bottom of the seat, and the pressure piece 402 between the two backboard support arms 403 is supported on the back of the backboard;

[0049] Furthermore, by using the rounded corner at one end of the pressure rod 501, the pressure rod 501 is passed through the inside of the two positioning rings 502 to ensure that the pressure rod 501 is located above the seat. When the two second hydraulic push rods 503 work simultaneously, the pressure rod 501 is pulled toward the connection point between the seat and the backboard, so that the seat can be fixed between the two pressure members 402.

[0050] Next, two first hydraulic push rods 405 with pressure sensors are controlled to pull the backboard support arm 403 and the seat support arm 401 to fold from the edge to the center, exerting pressure on the seat and the backboard to test the seat strength.

[0051] 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.
