Foam used inside cars may include seat foam and interior sound insulation foam. Seat foam typically requires good comfort and support to meet the needs of drivers and passengers.

[0003] Typically, testing devices are used to perform compression tests on automotive foam to ensure its future use. However, traditional automotive foam compression durability testing devices are not convenient for alternating tests on multiple foams, resulting in low testing efficiency. Therefore, it is necessary to develop an automotive foam compression durability testing device. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] An automotive foam compression durability testing device, comprising:

[0007] The base has a recessed mounting groove at its top, a lifting mechanism is provided inside the mounting groove, and a placement platform is provided on the top of the base via the lifting mechanism.

[0008] A gantry frame is fixedly installed on the top of the base above the placement platform. A horizontal rotating rod is rotatably arranged between the inner side walls of the gantry frame. Fixed rods are fixedly arranged at equal intervals on the rod body of the rotating rod. Connecting rods are hinged at the front and rear ends of the fixed rods. A pressure plate for pressing down and compressing sponge is provided at the bottom of the connecting rod. A vertical electric telescopic rod is fixedly installed at the top center of the gantry frame. The output shaft of the electric telescopic rod slides through the top wall of the gantry frame and is fixedly installed with a crossbar. At least one gear is fixedly installed on the rod body of the rotating rod. A vertical rack corresponding to and always meshing with the gear is provided at the lower end of the crossbar.

[0009] In a preferred embodiment of the automotive sponge compression durability testing device of this utility model, the top surface of the placement platform is recessed and provided with a placement groove for placing the sponge, and the placement groove is opened corresponding to the lower pressure plate.

[0010] As a preferred embodiment of the automotive sponge compression durability testing device of this utility model, the lifting mechanism includes a servo motor fixedly mounted on the bottom wall of the mounting slot. The output shaft of the servo motor is fixedly connected to a transverse double-ended screw via a coupling. Moving blocks are screwed onto the left and right sections of the double-ended screw. Each moving block has a support rod symmetrically hinged at its top. The tops of the four support rods are respectively hinged to the bottom of the placement platform.

[0011] In a preferred embodiment of the automotive sponge compression durability testing device of this utility model, a guide rod parallel to the positive and negative double-ended screw is fixedly provided on the inner side wall of the mounting groove, and the rod body of the guide rod slides through the side wall of the two moving blocks.

[0012] In a preferred embodiment of the automotive sponge compression durability testing device of this utility model, the bottom of the moving block is spaced apart from the bottom wall of the mounting groove, and a row of auxiliary support wheels is provided at the bottom of the moving block. When the moving block moves, the rollers of the auxiliary support wheels roll on the bottom wall of the mounting groove.

[0013] In a preferred embodiment of the automotive sponge compression durability testing device of this utility model, the number of the fixing rods is odd, and the rotating rod is fixed in the middle position of the fixing rods.

[0014] In a preferred embodiment of the automotive sponge compression durability testing device of this utility model, the number of gears is even, the gears and the fixed rod are arranged alternately in sequence, and the multiple gears are arranged symmetrically about the rotating rod.

[0015] The beneficial effects of this utility model are as follows: After placing the sponges to be tested one by one into a horizontal row of placement slots, the electric telescopic rod is activated to drive the horizontal bar to descend. The horizontal bar is driven to rotate through the rack and gear, thereby causing the lower pressure plate to descend and press down on the sponges at the bottom for a period of time. During the waiting period, other sponges to be tested can be placed one by one into another horizontal row of placement slots. After the test is completed, the rotating rod is controlled to rotate in the opposite direction, so that the lower pressure plate on the other side presses down on the sponges at the bottom for testing. At this time, the sponges in the previous horizontal row can be taken out to measure the thickness and check whether they can recover their deformation after compression or meet the specified requirements. This allows for alternating testing of sponges in the two horizontal rows, improving testing efficiency.

[0016] Furthermore, the distance between the sponge and the lower pressure plate can be further adjusted through the lifting mechanism, which allows for testing of sponges of different thicknesses and also adjusts the amount of pressure the lower pressure plate exerts on the sponge.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figures 1-5 The diagram shown is a structural schematic of an embodiment of the automotive sponge compression durability testing device of this utility model. Please refer to [link / reference]. Figures 1-5 This paper provides a detailed introduction to an automotive sponge compression durability testing device.

[0029] An automotive sponge compression durability testing device includes a base 100, with an indented mounting groove 101 on the top of the base 100. A lifting mechanism is provided inside the mounting groove 101, and a placement platform 102 is provided on the top of the base 100 via the lifting mechanism.

[0030] A gantry frame 200 is fixedly installed on the top of the base 100 above the placement platform 102. A horizontal rotating rod 201 is rotatably arranged between the inner side walls of the gantry frame 200. Fixed rods 202 are fixedly arranged at equal intervals on the rod of the rotating rod 201. Connecting rods 203 are hinged at the front and rear ends of the fixed rods 202. A pressure plate 204 for pressing down and compressing the sponge is provided at the bottom of the connecting rod 203. A vertical electric telescopic rod 205 is fixedly installed at the top center of the gantry frame 200. The output shaft of the electric telescopic rod 205 slides through the top wall of the gantry frame 200 and is fixedly installed with a crossbar 206. At least one gear 207 is fixedly installed on the rod of the rotating rod 201. A vertical rack 208 corresponding to and always meshing with the gear 207 is provided at the lower end of the crossbar 206.

[0031] Wherein: the top surface of the placement platform 102 is recessed and a placement groove 103 for placing sponges is provided. The placement groove 103 is opened corresponding to the lower pressure plate 204. The sponge is placed in the lower pressure plate 204 for easy compression.

[0032] The lifting mechanism includes a servo motor 104 fixedly mounted on the bottom wall of the mounting groove 101. The output shaft of the servo motor 104 is fixedly connected to a transverse double-ended screw 105 via a coupling. Moving blocks 106 are screwed onto the left and right sections of the double-ended screw 105. Each moving block 106 has a support rod 107 symmetrically hinged to its top. The tops of the four support rods 107 are respectively hinged to the bottom perimeter of the placement platform 102. A guide rod 108 parallel to the double-ended screw 105 is fixedly mounted on the inner wall of the mounting groove 101. The guide rod 108 slides through the two moving blocks 105. The side wall of block 106, the bottom of the movable block 106 and the bottom wall of the mounting groove 101 are spaced apart, and the bottom of the movable block 106 is provided with a row of auxiliary support wheels 109. When the movable block 106 moves, the rollers of the auxiliary support wheels 109 roll on the bottom wall of the mounting groove 101. The servo motor 104 is started to drive the positive and negative double-headed screw 105 to rotate, thereby adjusting the distance between the two movable blocks 106. Then, the height of the placement platform 102 is adjusted by the support rod 107, thereby further adjusting the distance between the sponge and the lower pressure plate 204. That is, it is possible to test sponges of different thicknesses, which is also equivalent to adjusting the amplitude of the lower pressure plate 204 pressing down on the sponge.

[0033] Wherein: the number of fixed rods 202 is odd, the rotating rod 201 is fixed in the middle position of the fixed rods 202, the number of gears 207 is even, the gears 207 and the fixed rods 202 are arranged alternately in sequence, and the multiple gears 207 are arranged symmetrically about the rotating rods 201. This design makes the rotating rods 201 more evenly stressed.

[0034] In practical use, after placing the sponges to be tested one by one into the horizontal placement slots 103, the electric telescopic rod 205 is activated to drive the horizontal bar 206 to descend. The horizontal bar 206 is driven to rotate through the rack 208 and gear 207, thereby causing the lower pressure plate 204 to descend and press down on the sponges at the bottom for a period of time. During the waiting period, other sponges to be tested can be placed one by one into the other horizontal placement slots 103. After the test is completed, the rotating rod 201 is controlled to rotate in the opposite direction, so that the lower pressure plate 204 on the other side presses down on the sponges at the bottom for testing. At this time, the sponges in the previous horizontal row can be taken out to measure the thickness and check whether they can recover their deformation after compression or meet the specified requirements. This allows for alternating testing of sponges in the two horizontal rows, improving testing efficiency.

[0035] Furthermore, the distance between the sponge and the lower pressure plate 204 can be further adjusted through the lifting mechanism, which allows for testing of sponges of different thicknesses and also adjusts the amount of pressure exerted by the lower pressure plate 204 on the sponge.

[0036] It should be noted that in this embodiment, the electric telescopic rod 205 is used to push the rack 208 up and down, thereby driving the gear 207 to rotate. The purpose is only to control the rotation and locking of the rotating rod 201. Other mechanisms, such as worm gear mechanisms or motor gear mechanisms, can also be used to drive the rotating rod 201 to rotate in this embodiment.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
