Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle mechanical component testing, and more specifically, to a sliding durability simulation test device for automotive window sealing strips. Background Art

[0002] Automotive sealing strips are also one of the important parts of new energy vehicles with pure electric drive, and are widely used in doors, windows and other parts. They have the functions of sound insulation, dust prevention, water seepage prevention and shock absorption, and play an important protective role for new energy vehicle users, electromechanical devices and accessories. However, once the rubber ages and breaks, a series of problems such as rain leakage may occur. Therefore, before mass production and use of the sealing strip, it is necessary to conduct a sliding durability test to ensure the stability of the new energy vehicle rubber strip under friction conditions, avoid seal failure or abnormal noise caused by wear, and obtain its service life under the opening and closing of the window glass.

[0003] In the prior art, for sliding durability tests, relative movement between the glass and the sealing strip is mostly driven by a reciprocating mechanism, or relative movement between the sealing strip and the glass is driven to detect the sliding friction loss of the sealing strip. Whether the slider action end directly drives the glass or the sealing strip, in such test devices, there are the following disadvantages in use, that is, when the slider action end moves to the extreme position, that is, when turning back at the turning point, it will experience rapid deceleration and rapid acceleration. Due to inertia, the glass or the sealing strip will have a tendency of relative movement with respect to the slider action end. If it is the sealing strip, due to its own elasticity, it will deform under inertia. In the case of accumulation over time, it will cause material fatigue of the sealing strip itself, increasing its own loss. If it is the glass, it will be subjected to an acceleration in the opposite direction at the turning points at both ends, that is, it will cause the glass to be subjected to non-constant forces during reciprocating motion. Under long-term motion, it is likely to break, thus in the sliding durability test, there are other loss situations of the test materials in addition to the sliding friction loss, resulting in the test results being affected.

[0004] To solve the above problems, a sliding durability simulation test device for automotive window sealing strips is proposed. Summary of the Invention

[0005] To solve the above technical problems, a sliding durability simulation test device for automotive window sealing strips is provided, and the present technical solution solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention may adopt the following technical solutions:

[0007] The present invention provides a sliding durability simulation test device for automotive window sealing strips, including:

[0008] The test bench has six turntables rotatably connected to the periphery of its tabletop. A vise is fixedly connected to the top of each turntable, and a profiled sheet metal is clamped inside each vise. A sealing strip is fixedly connected to the top of each profiled sheet metal. A secondary shaft is fixedly connected to the bottom of each turntable, and a first shaft seat is rotatably connected to the outside of each secondary shaft. One side of each shaft seat is fixedly connected to the inner wall of the test bench. The bottom ends of the secondary shafts are fixedly connected with a first sprocket, and the outsides of the first sprockets are jointly engaged inside the same chain. A double-shaft extension motor is fixedly installed on one side of the inner wall of the test bench. The upper driving end of the double-shaft extension motor is fixedly connected with a one-way bearing, and a second sprocket is fixedly connected to the outside of the one-way bearing. The second sprocket is engaged with the outside of the chain. The lower driving end of the double-shaft extension motor is fixedly connected with an eccentric wheel;

[0009] The main shaft is arranged above the test bench. Both sides of its bottom end are fixedly connected with side arms, and an H-shaped bracket is fixedly connected to the middle of each side arm. A suction cup is fixedly connected to the bottom end of each H-shaped bracket, and glass is adsorbed on the bottom of each suction cup.

[0010] Furthermore, a reduction motor is fixedly connected to the top end of the main shaft.

[0011] Furthermore, it further includes a pressure adjustment component, which includes a gantry arranged on one side of the test bench. A lifting slide is fixedly connected to the middle of the gantry. The side of the slider of the lifting slide is fixedly connected with the reduction motor, and a second shaft seat is fixedly connected to the bottom of the slider of the lifting slide. The outside of the main shaft is rotatably connected to the inside of the second shaft seat.

[0012] Furthermore, the pressure adjustment component further includes an electric cylinder. The electric cylinder is fixedly connected to the cross frame in the middle of the bottom of the test bench. The top of the telescopic end of the electric cylinder is fixedly connected with a lifting rod. The outside of the lifting rod is slidably connected to the middle of the test bench. A groove is opened at the top end of the lifting rod, a pressure sensor is fixedly connected to the bottom of the groove, and a T-shaped bracket is arranged on the force-receiving end of the pressure sensor.

[0013] Furthermore, it further includes a protection component, which includes a protection cover. The middle of the protection cover is fixedly connected to the outside of the main shaft, and the protection cover is located above the side arms.

[0014] Furthermore, the protection component further includes a protection cylinder. The bottom end of the protection cylinder is clamped at the top edge of the test bench. An electric heater is fixedly installed in the middle of one side of the protection cylinder, and the heating direction of the electric heater points to the inside of the protection cylinder. A temperature sensor is fixedly installed in the middle of the side of the protection cylinder away from the electric heater.

[0015] Furthermore, it further includes a support component, which includes four feet. The four feet are evenly spaced around the bottom of the test bench. Six springs are fixedly connected to the top of each foot, and the top ends of the springs are respectively fixedly connected to the bottom end of the test bench.

[0016] Furthermore, the support assembly further includes eight guide rods. Sleeve bushes are slidably connected to the outsides of the guide rods. The eight guide rods are grouped in pairs, and each group of guide rods corresponds to a support leg. The bottom ends of each group of guide rods are fixedly connected to the two ends of the top of each support leg respectively, and the sides of the sleeve bushes are fixedly connected to the sides of the test bench respectively.

[0017] As described above, the characteristics and advantages of an automotive window sealing strip sliding durability simulation test device in the present invention are:

[0018] By driving the pressure sensor and the T-shaped frame to move up and down, the pressure when the glass descends to a certain height and starts to press down on the top plane of the T-shaped frame can be measured, so as to directly convert the pressure on the sealing strip when the glass is pressed down to this height. Through the fine adjustment of the lifting of the glass by the lifting slide table, the pressure during the sliding between the glass and the sealing strip can be accurately controlled, so that the test results are more accurate.

[0019] By driving the glass to rotate by the main shaft and fixing multiple sealing strips with the bench vice, multiple test groups can be tested at one time, thus avoiding the situation in the prior art that when the reciprocating mechanism drives the glass and the sealing strip, it will cause material fatigue of the sealing strip itself, and the force on the glass during the reciprocating movement is not constant, and the glass is prone to breakage under long-term movement. Therefore, in the sliding durability test, there are other loss situations in addition to the sliding friction loss of the test materials, resulting in the test results being affected. At the same time, the sealing strip can rotate automatically to exchange the positions of its inner and outer ends, avoiding the situation that due to the glass being in a rotating state, the linear velocities on the inner and outer sides of its circular motion are inconsistent, resulting in different sliding conditions between the inner and outer ends of the sealing strip on the inner and outer sides of the circle and the glass, thus causing inconsistent test conditions and making the test results more reliable. On the contrary, through the above structural characteristics, the sliding durability of the same sealing strip at different speeds and frequencies can also be tested.

[0020] By synchronously rotating multiple sealing strips automatically, the situation of manually changing the position and angle of the sealing strip by manpower is eliminated, and the use efficiency is improved. On the contrary, through the vibration of the test bench, the bumps of the vehicle are simulated, as well as the situation of the body resonance driven by a new energy vehicle during operation, so as to achieve the purpose of simulating other environments.

[0021] By monitoring the temperature inside the protective cylinder heated by the electric heater through the temperature sensor, different environmental temperatures can be simulated, further enriching the test project conditions. At the same time, the cooperation between the protective cover and the protective cylinder can not only play a heat preservation role, but also play the purpose of protecting the safety of test personnel, that is, avoiding the situation that the glass breaks and injures people due to strong shaking and the interaction force with the sealing strip when the glass is in a rotating state.

[0038] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0039] Refer to Figures 1 - 7 As shown, it is an embodiment of the present invention, and an automotive window seal sliding durability simulation test device provided will be elaborated in detail below:

[0040] An automotive window seal sliding durability simulation test device includes a test bench 101, with six turntables 102 rotatably connected to the periphery of its tabletop. A bench vise 103 is fixedly connected to the top of each turntable 102. A profiled sheet metal 104 is clamped in each bench vise 103. A seal strip 105 is fixedly connected to the top of each profiled sheet metal 104. A secondary shaft 106 is fixedly connected to the bottom of each turntable 102. A first shaft seat 107 is rotatably connected to the outside of each secondary shaft 106. The sides of the first shaft seats 107 are respectively fixedly connected to the inner wall of the test bench 101. A first sprocket 108 is fixedly connected to the bottom end of each secondary shaft 106. The outsides of the first sprockets 108 are jointly engaged inside the same chain 109. A double-shaft extension motor 110 is fixedly installed on one side of the inner wall of the test bench 101. A one-way bearing 111 is fixedly connected to the upper driving end of the double-shaft extension motor 110. The one-way bearing 111 belongs to the prior art, and only relative rotation can occur in one direction between its inner and outer steel rings, otherwise it is locked. It is a direct application of a mature technology and will not be elaborated here. A second sprocket 112 is fixedly connected to the outside of the one-way bearing 111. The second sprocket 112 is engaged outside the chain 109, and the second sprocket 112 drives the first sprocket 108 through the chain 109. An eccentric wheel 113 is fixedly connected to the lower driving end of the double-shaft extension motor 110.

[0041] Refer to Figures 3 - 4 As shown, it further includes a main shaft 201, which is arranged above the test bench 101. The top end of the main shaft 201 is fixedly connected to a reduction motor 202, that is, connected to the output shaft of the reduction motor 202.

[0042] Furthermore, refer to Figure 1 and Figure 9As shown, it further includes a pressure adjustment component, which includes a gantry 301 arranged on one side of the test bench 101. A lifting slide 302 is fixedly connected in the middle of the gantry 301. The side of the slider of the lifting slide 302 is fixedly connected to the reduction motor 202. The bottom of the slider of the lifting slide 302 is fixedly connected to a second shaft seat 303. The outside of the main shaft 201 is rotatably connected inside the second shaft seat 303.

[0043] In this embodiment, refer to Figure 9 As shown, the lifting slide 302 includes a fixed electric slide rail, and a slider is slidably connected to the electric slide rail. The electric slide rail is started to drive the slider, so as to achieve the lifting effect.

[0044] Furthermore, both sides of the bottom end of the main shaft 201 are fixedly connected with side arms 203. H-shaped brackets 204 are fixedly connected in the middle of the side arms 203. Suction cups 205 are fixedly connected to the bottom ends of the H-shaped brackets 204. Glass 206 is adsorbed at the bottom of each suction cup 205.

[0045] In this embodiment, the installation method between the H-shaped bracket 204 and the side arm 203 is that a hole penetrating up and down is opened in the middle of the side arm 203. The H-shaped bracket 204 is inserted into the hole, and the H-shaped bracket 204 is fixed firmly on the side arm 203 by screwing a bolt on the side to press it tightly. The advantage of this method is that the height of the glass 206 can be adjusted to adapt to different simulation test situations. The suction cup 205 adopts existing mature technology and will not be elaborated here.

[0046] Furthermore, refer to Figure 5 As shown, in order to improve the tension of the chain 109, a tensioning sprocket is arranged opposite to the double-shaft extension motor 110, and it is connected to the inner wall of the test bench 101 through a mounting bracket.

[0047] Furthermore, in order to improve the authenticity of the test simulation, first, the window part corresponding to the sealing strip 105 to be tested is subjected to profiling treatment, that is, a profiling sheet metal 104 with the same shape as the window part is made of metal material, and then the sealing strip 105 to be tested is assembled correspondingly. The assembly technology adopts the mature assembly technology of existing vehicle manufacturing factories, such as pasting with structural adhesive, or gently pressing and clamping the sealing strip 105 along the slot of the window frame. This will not be elaborated here.

[0048] The above-mentioned method rotates the glass 206 driven by the main shaft 201, and fixes multiple sealing strips 105 by the vise 103, enabling multiple test groups to be tested at one time. Thus, it avoids the situation in the prior art that when the reciprocating mechanism drives the glass 206 and the sealing strip 105, it will cause material fatigue of the sealing strip 105 itself, and the force on the glass 206 is not constant during the reciprocating motion, and it is prone to breakage under long-term motion. Therefore, in the sliding durability test, there are other loss situations of the test materials in addition to the sliding friction loss, resulting in the influence on the test results. At the same time, the sealing strip 105 can rotate itself to change its different body position angles, avoiding the situation that due to the glass 206 being in a rotating state, the linear velocities on the inner and outer sides of its circular motion are inconsistent, so that the sliding conditions between the inner and outer ends of the sealing strip 105 on the inner and outer sides of the circle and the glass 206 are different, resulting in inconsistent test conditions, making the test results more reliable.

[0049] Further, referring to Figure 2 and Figure 8 As shown, the pressure adjustment assembly further includes an electric cylinder 304. The electric cylinder 304 is fixedly connected to the cross frame in the middle of the bottom of the test bench 101. The top of the telescopic end of the electric cylinder 304 is fixedly connected with a lifting rod 305. The outside of the lifting rod 305 is slidably connected to the middle part of the test bench 101. A groove is opened at the top end of the lifting rod 305, and a pressure sensor 306 is fixedly connected to the bottom of the groove. A T-shaped frame 307 is provided on the force receiving end of the pressure sensor 306. The T-shaped frame 307 includes a horizontal force receiving plate part and a force transmission column part vertically and fixedly installed in the middle of the bottom of the horizontal force receiving plate. Among them, the force transmission column part is fitted inside the groove.

[0050] In this embodiment, when the two pieces of glass 206 press on both sides of the T-shaped frame 307, that is, when they press on both ends of the horizontal force receiving plate respectively, the pressure can be transmitted downward through the force transmission column, and then the pressure sensor 306 is used to measure the pressure, so as to convert the pressure between the glass 206 and the sealing strip 105.

[0051] Further, referring to Figure 1 As shown, it further includes a protection assembly, which includes a protection cover 401. The middle of the protection cover 401 is fixedly connected to the outside of the main shaft 201, and the protection cover 401 is located above the side arm 203.

[0052] Further, the protection assembly further includes a protection cylinder 402. The bottom end of the protection cylinder 402 is clamped at the top edge of the test bench 101, and the protection cylinder 402 has the same diameter size as the test bench 101. An electric heater 403 is fixedly installed in the middle of one side of the protection cylinder 402, and the heating direction of the electric heater 403 points to the inside of the protection cylinder 402. A temperature sensor 404 is fixedly installed in the middle of the side of the protection cylinder 402 away from the electric heater 403.

[0053] In this embodiment, the temperature sensor 404 is used to monitor the temperature inside the protective cylinder 402 heated by the electric heater 403, so as to simulate different ambient temperatures. At the same time, since the glass 206 is in a rotating state, strong shaking and the interaction force with the sealing strip 105 make the glass 206 likely to break. Through the cooperation between the protective cover 401 and the protective cylinder 402, the safety of the test personnel can be protected.

[0054] Refer to Figure 1 and Figure 10 As shown, it further includes a support assembly, which includes four feet 501. The four feet 501 are evenly spaced around the bottom of the test bench 101. Six springs 504 are fixedly connected to the top of each foot 501, and the top ends of the springs 504 are respectively fixedly connected to the bottom end of the test bench 101.

[0055] The support assembly further includes eight guide rods 502. Sleeve 503 is slidably connected to the outside of the guide rods 502. Two of the eight guide rods 502 form a group, and each group of guide rods 502 corresponds to one foot 501 respectively. The bottom ends of each group of guide rods 502 are respectively fixedly connected to both ends of the top of each foot 501, and the sides of the sleeves 503 are respectively fixedly connected to the sides of the test bench 101.

[0056] When the eccentric wheel 113 drives the test bench 101 to vibrate, the vibration transmission between the test bench 101 and the feet 501 is reduced through the springs 504. Conversely, it can also be explained that when the test bench 101 is connected to the ground through the feet 501, the springs 504 can reduce the limitation of the vibration amplitude of the fixed feet 501 on the test bench 101. Further, in order to improve the stability of the test bench 101 during vibration, through the support and guidance of the sleeve 503 on the guide rod 502, the vibration of the test bench 101 can be controlled within a certain range.

[0057] Combined with the above embodiments, the following is the entire working process and working principle of the above embodiments:

[0058] The working state is as follows: The sealing strip 105 to be tested is correspondingly assembled on the profiling sheet metal 104, and then fixed inside the bench vice 103 together with the sealing strip 105, and the heights of the sealing strips 105 in each bench vice 103 are kept the same. The glass 206 is installed at the bottom of the main shaft 201 through the suction cup 205, and then the electric cylinder 304 extends to raise the lifting rod 305 until the top plane of the T-shaped frame 307 is at the same height as the sealing strip 105. Then, the lifting slide 302 on the gantry 301 is started, and the reduction motor 202 is driven to descend, thereby synchronously driving the main shaft 201, the side arm 203, the H bracket 204, the suction cup 205 and the glass 206 to descend synchronously. When the glass 206 descends and starts to press the top plane of the T-shaped frame 307, through the transmission of force, the pressure sensor 306 can be used to measure the pressure when the glass 206 presses down at this time. Thus, the operator can observe the pressure on the sealing strip 105 from the control panel. After obtaining the required pressure, the height of the lifting slide 302 is locked, and the electric cylinder 304 contracts to make the lifting rod 305 and the T-shaped frame 307 descend and reset.

[0059] Further, the reduction motor 202 drives the main shaft 201 to rotate. Thus, supported by the second shaft seat 303, the two pieces of glass 206 are driven to rotate through the side arm 203 and the H bracket 204. In this way, when the sealing strip 105 remains stationary, the sliding durability test of the sealing strip 105 can be carried out.

[0060] Further, since the glass 206 is in a rotating state, the linear velocities on the inner and outer sides of the natural circular motion are inconsistent, so that the sliding conditions between the inner and outer end parts of the sealing strip 105 on the inner and outer sides of the circumference and the glass 206 are different, resulting in inconsistent test conditions. Therefore, the double-shaft extension motor 110 drives the sprocket two 112 to rotate slowly through the one-way bearing 111, and then drives the sprocket one 108 to rotate through the chain 109. The sprocket one 108 is supported by the first shaft seat 107 and drives the bench vice 103 on the turntable 102 to rotate through the auxiliary shaft 106, and finally drives the sealing strip 105 to rotate self, and exchanges the position of the end close to the center of the test bench 101 with the end close to the edge of the test bench 101, so that the sliding conditions between the inner and outer end parts of the sealing strip 105 and the glass 206 are the same.

[0061] Conversely, through the above structural characteristics, the sliding durability of the same sealing strip 105 at different speeds and frequencies can also be tested.

[0062] Further, when the double-extended motor 110 rotates at high speed in the reverse direction, due to the effect of the one-way bearing 111, at this time, the double-extended motor 110 will not be able to drive the second sprocket 112 to rotate in the reverse direction. Instead, due to the instability of the rapid rotation of the eccentric wheel 113, the test bench 101 vibrates, so that the sliding between the sealing strip 105 and the glass 206 is in a vibrating environment, thereby simulating the bumps of the car and the resonance of the vehicle body driven by the engine during operation. During vibration, the vibration transmission between the test bench 101 and the support feet 501 is reduced by the spring 504. On the contrary, it can also be explained that when the test bench 101 is connected to the ground through the support feet 501, the spring 504 can reduce the limitation of the fixed support feet 501 on the vibration amplitude of the test bench 101. Further, in order to improve the stability of the test bench 101 during vibration, the vibration of the test bench 101 can be controlled within a certain range by the support and guidance of the rod sleeve 503 for the guide rod 502.

[0063] Further, the temperature inside the protective cylinder 402 heated by the electric heater 403 is monitored by the temperature sensor 404 to simulate different ambient temperatures. At the same time, since the glass 206 is in a rotating state, the strong shaking and the interaction force with the sealing strip 105 make the glass 206 likely to break. The cooperation between the protective cover 401 and the protective cylinder 402 protects the safety of the test personnel.

[0064] Naturally, by selecting different glasses 206, different sliding conditions between the glass 206 and the sealing strip 105 can be simulated. For example, the rough glass 206 can simulate the sliding condition between the glass 206 and the sealing strip 105 when the glass 206 is contaminated with dust.

[0065] Further, if a whole round glass 206 is selected as the test object, it can be stably adsorbed by the two suction cups 205 on both sides at this time. In this way, when it is pressed and rotated, it will always remain in contact with the sealing strip 105, thereby simulating the situation when the glass 206 is half-opened in the car window, that is, the bottom part of it is always pressing the sealing strip 105.
