Description

Technical Field

[0001] This invention relates to the field of testing technology for mechanical components of new energy vehicles, and more specifically, to a simulation test device for the sliding durability of automotive window sealing strips. Background Technology

[0002] Automotive sealing strips are also one of the important components of pure electric new energy vehicles. They are widely used in car doors, windows and other parts, and have the functions of sound insulation, dust prevention, water prevention and shock absorption. They play an important role in protecting new energy vehicle users, electromechanical devices and accessories. However, once the rubber ages and breaks down, it may lead to a series of problems such as rain leakage. Therefore, before the sealing strips are mass-produced and used, they need to undergo sliding durability testing to ensure the stability of the rubber strips under friction conditions, avoid sealing failure or abnormal noise due to wear, and determine their service life under the opening and closing of car windows.

[0003] In existing technologies, sliding durability testing often involves a reciprocating mechanism that moves the glass and sealing strip relative to each other, or vice versa, to detect the sliding friction loss of the sealing strip. Regardless of whether the sliding block directly moves the glass or the sealing strip, this type of testing device has the following drawbacks: when the sliding block reaches its limit position, i.e., when it turns back at the reversal point, it experiences rapid deceleration and acceleration. Due to inertia, the glass or sealing strip tends to move relative to the sliding block. If it is the sealing strip, its elasticity will cause deformation under inertia, which, over time, leads to material fatigue and increased wear. If it is the glass, it will be subjected to acceleration in the opposite direction at the reversal points, resulting in inconsistent forces during the reciprocating motion. Over a long period of time, this can easily cause breakage. Thus, in the sliding durability test, other forms of wear besides sliding friction loss occur in the test material, affecting the test results.

[0004] To address the aforementioned issues, a simulation test device for the sliding durability of automotive window sealing strips is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a simulation test device for the sliding durability of automotive window sealing strips is provided. This technical solution solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions:

[0007] This invention provides a simulation test device for the sliding durability of automotive window sealing strips, comprising:

[0008] The test bench has six turntables rotatably connected around its surface. Each turntable is fixedly connected to a vise on top, and each vise holds a profile sheet metal. Each profile sheet metal is fixedly connected to a sealing strip on top. Each turntable is fixedly connected to a secondary shaft, and each secondary shaft is rotatably connected to a bearing seat. The side of each bearing seat is fixedly connected to the inner wall of the test bench. Each secondary shaft is fixedly connected to a sprocket, and the external parts of the sprockets are engaged with the same chain. A dual-shaft extension motor is fixedly installed on one side of the inner wall of the test bench. The upper drive end of the dual-shaft extension motor is fixedly connected to a one-way bearing, and the external part of the one-way bearing is fixedly connected to a sprocket, which engages with the chain. The lower drive end of the dual-shaft extension motor is fixedly connected to an eccentric wheel.

[0009] The main shaft is located above the test bench, with side arms fixedly connected to both sides of its bottom end. H-braces are fixedly connected to the middle of each side arm, and suction cups are fixedly connected to the bottom of each H-braces. Glass is adsorbed at the bottom of each suction cup.

[0010] Furthermore, a geared motor is fixedly connected to the top of the spindle.

[0011] Furthermore, it also includes a pressure adjustment assembly, which includes a gantry located on one side of the test bench, a lifting slide fixedly connected in the middle of the gantry, a slider side of the lifting slide fixedly connected to a reduction motor, a second bearing fixedly connected to the bottom of the slider of the lifting slide, and the external rotation of the main shaft connected to the inside of the second bearing.

[0012] Furthermore, the pressure adjustment assembly also includes an electric cylinder, which is fixedly connected to the crossbeam in the middle of the bottom of the test bench. A lifting rod is fixedly connected to the top of the telescopic end of the electric cylinder. The lifting rod is slidably connected to the middle of the test bench. A groove is provided at the top of the lifting rod, and a pressure sensor is fixedly connected to the bottom of the groove. A T-shaped bracket is provided on the force-receiving end of the pressure sensor.

[0013] Furthermore, it also includes a protective assembly, which includes a protective cover that is fixedly connected in the middle to the outside of the main shaft and is located above the side arm.

[0014] Furthermore, the protective assembly also includes a protective cylinder, the bottom of which is snapped onto the top edge of the test bench. An electric heater is fixedly installed in the middle of one side of the protective cylinder, with the heating direction of the electric heater pointing towards the inside of the protective cylinder. A temperature sensor is fixedly installed in the middle of the side of the protective cylinder away from the electric heater.

[0015] Furthermore, it also includes a support assembly, which includes four legs evenly spaced around the bottom of the test bench. Each leg has six springs fixedly connected to its top, with the top of each spring fixedly connected to the bottom of the test bench.

[0016] Furthermore, the support assembly also includes eight guide rods, each of which is slidably connected to a sleeve. The eight guide rods are grouped in pairs, with each group of guide rods corresponding to a support leg. The bottom end of each group of guide rods is fixedly connected to the top two ends of each support leg, and the sides of the sleeves are fixedly connected to the sides of the test bench.

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

[0018] By driving the pressure sensor and the T-shaped frame to rise and fall, the pressure when the glass falls to a certain height and begins to press down on the top plane of the T-shaped frame can be measured. This allows for the direct calculation of the pressure on the sealing strip when the glass is pressed down to that height. By finely adjusting the rise and fall of the glass through the lifting slide, the pressure when the glass slides against the sealing strip can be precisely controlled, thus making the test results more accurate.

[0019] By using a spindle to rotate the glass and a vise to fix multiple sealing strips, multiple test groups can be performed simultaneously. This avoids the material fatigue of the sealing strip itself and the inconsistent force on the glass during the reciprocating motion, which can easily lead to breakage under prolonged operation, as seen in existing technologies where the reciprocating mechanism drives the glass and sealing strip. This results in material loss other than sliding friction loss in the sliding durability test, affecting the test results. At the same time, the sealing strip can rotate to exchange the positions of its inner and outer ends, avoiding the inconsistent linear velocities on the inner and outer sides of the rotating glass. This prevents the sliding conditions between the inner and outer ends of the sealing strip and the glass from being inconsistent, thus making the test results more reliable. Conversely, the above structural features can also be used to test the sliding durability of the same sealing strip at different speeds and frequencies.

[0020] By synchronously rotating multiple sealing strips, the need for manual adjustment of the sealing strip position and angle is eliminated, improving efficiency. Conversely, by vibrating the test bench, the bumps of a car and the resonance of the vehicle body caused by the operation of a new energy vehicle are simulated, thus achieving the purpose of simulating other environments.

[0021] By monitoring the temperature inside the protective cylinder with a temperature sensor, different ambient temperatures can be simulated, further enriching the experimental conditions. At the same time, the cooperation between the protective cover and the protective cylinder not only serves to keep the temperature warm, but also to protect the safety of the test personnel. This avoids the situation where the glass breaks and injures people due to the strong swinging of the glass while it is rotating and the interaction force between it and the sealing strip.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] See Figures 1-7 As shown in the figure, an embodiment of the present invention is provided, and a sliding durability simulation test device for automotive window sealing strips will be described in detail below:

[0040] A simulation test device for the sliding durability of automotive window sealing strips includes a test bench 101. Six turntables 102 are rotatably connected to the bench surface. A vise 103 is fixedly connected to the top of each turntable 102, and each vise 103 holds a contour sheet metal 104. A sealing strip 105 is fixedly connected to the top of each contour sheet metal 104. A secondary shaft 106 is fixedly connected to the bottom of each turntable 102. A bearing seat 107 is rotatably connected to the outside of each secondary shaft 106. The sides of the bearing seats 107 are fixedly connected to the inner wall of the test bench 101. A sprocket 108 is fixedly connected to the bottom of each secondary shaft 106. The external surfaces of the sprockets 108 cooperate with the same... Inside the chain 109, a dual-shaft extension motor 110 is fixedly installed on one side of the inner wall of the test bench 101. The upper drive end of the dual-shaft extension motor 110 is fixedly connected to a one-way bearing 111. The one-way bearing 111 is existing technology. Its inner and outer steel rings can only rotate relative to each other in one direction. Otherwise, they are locked. It is a direct application of mature technology and will not be described in detail here. A second sprocket 112 is fixedly connected to the outside of the one-way bearing 111. The second sprocket 112 is fitted to the outside of 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 drive end of the dual-shaft extension motor 110.

[0041] See Figures 3-4 As shown, it also includes a main shaft 201, which is located above the test bench 101. A geared motor 202 is fixedly connected to the top of the main shaft 201, that is, it is connected to the output shaft of the geared motor 202.

[0042] Further reading Figure 1 and Figure 9As shown, it also includes a pressure adjustment assembly, which includes a gantry 301 located on one side of the test bench 101. A lifting slide 302 is fixedly connected to the middle of the gantry 301. The side of the slider of the lifting slide 302 is fixedly connected to the reduction motor 202. A bearing seat 303 is fixedly connected to the bottom of the slider of the lifting slide 302. The external shaft 201 is rotatably connected to the inside of the bearing seat 303.

[0043] In this embodiment, see Figure 9 As shown, the lifting slide 302 includes a fixed electric slide rail, on which a slider is slidably connected. When the electric slide rail is activated, it drives the slider to achieve the lifting effect.

[0044] Furthermore, side arms 203 are fixedly connected to both sides of the bottom end of the main shaft 201, H brackets 204 are fixedly connected to the middle of the side arms 203, suction cups 205 are fixedly connected to the bottom of the H brackets 204, and glass 206 is adsorbed at the bottom of the suction cups 205.

[0045] In this embodiment, the H-bracket 204 and the side arm 203 are installed in such a way that a through hole is opened in the middle of the side arm 203, and the H-bracket 204 is inserted into the hole. The H-bracket 204 is firmly fixed to the side arm 203 by bolts connected by side threads. The advantage of this method is that the height of the glass 206 can be adjusted to adapt to different simulation test conditions. The suction cup 205 adopts existing mature technology, which will not be described in detail here.

[0046] Further reading Figure 5 As shown, in order to improve the tension of the chain 109, a tensioning sprocket is provided opposite the dual-shaft extension motor 110, which is connected to the inner wall of the test bench 101 by a mounting bracket.

[0047] Furthermore, in order to improve the realism of the test simulation, the window part corresponding to the sealing strip 105 to be tested is first processed by contouring, that is, a contoured sheet metal 104 with the same shape as the window part is made of metal material. Then, the sealing strip 105 to be tested is assembled accordingly. The assembly technology adopts the existing mature assembly technology of car manufacturers, such as bonding with structural adhesive, or gently pressing the sealing strip 105 along the groove of the window frame to lock it in place, which will not be described in detail here.

[0048] The aforementioned method, which uses the main shaft 201 to rotate the glass 206 and uses the vise 103 to fix multiple sealing strips 105, allows for the simultaneous testing of multiple test groups. This avoids the material fatigue of the sealing strips 105 themselves caused by the reciprocating mechanism driving the glass 206 and sealing strips 105 in the prior art, as well as the inconsistent force on the glass 206 during reciprocating motion, which can easily lead to breakage over long periods of time. Consequently, in the sliding durability test, other losses of the test material besides sliding friction loss occur, affecting the test results. At the same time, the sealing strips 105 can rotate to change their different body angles, avoiding the inconsistent linear velocities on the inner and outer sides of the circumference of the rotating glass 206. This prevents the sliding conditions between the inner and outer ends of the sealing strips 105 and the glass 206 from being inconsistent, thus causing inconsistent test conditions and making the test results more reliable.

[0049] Further reading Figure 2 and Figure 8 As shown, the pressure adjustment assembly also includes an electric cylinder 304, which is fixedly connected to the crossbeam in the middle of the bottom of the test bench 101. A lifting rod 305 is fixedly connected to the top of the telescopic end of the electric cylinder 304. The lifting rod 305 is slidably connected to the middle of the test bench 101. A groove is provided at the top of the lifting rod 305. 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 and a force transmission column that is vertically fixedly installed in the middle of the bottom of the horizontal force-receiving plate. The force transmission column fits inside the groove.

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

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

[0052] Furthermore, the protective assembly also includes a protective cylinder 402, the bottom end of which is snapped onto the top edge of the test bench 101, and the diameter of the protective cylinder 402 is the same as that of the test bench 101. An electric heater 403 is fixedly installed in the middle of one side of the protective cylinder 402, and the heating direction of the electric heater 403 is pointing towards the inside of the protective cylinder 402. A temperature sensor 404 is fixedly installed in the middle of the side of the protective cylinder 402 away from the electric heater 403.

[0053] In this embodiment, the temperature sensor 404 monitors the temperature inside the protective cylinder 402 heated by the electric heater 403 to simulate different ambient temperatures. At the same time, since the glass 206 is in a rotating state, the strong swinging and the interaction force between it and the sealing strip 105 make the glass 206 potentially breakable. The cooperation between the protective cover 401 and the protective cylinder 402 protects the safety of the test personnel.

[0054] See Figure 1 and Figure 10 As shown, it also includes a support assembly, which includes four legs 501. The four legs 501 are evenly spaced around the bottom of the test bench 101. Each leg 501 has six springs 504 fixedly connected to its top. The top of each spring 504 is fixedly connected to the bottom of the test bench 101.

[0055] The support assembly also includes eight guide rods 502, each of which is slidably connected to a sleeve 503. The eight guide rods 502 are grouped in pairs, and each group of guide rods 502 corresponds to a support leg 501. The bottom end of each group of guide rods 502 is fixedly connected to the top two ends of each support leg 501, and the sides of the sleeves 503 are fixedly connected to the sides of the test bench 101.

[0056] As mentioned above, when the eccentric wheel 113 drives the test bench 101 to vibrate, the spring 504 reduces the vibration transmission between the test bench 101 and the support leg 501. Conversely, when the test bench 101 is connected to the ground by the support leg 501, the spring 504 can reduce the limitation of the fixed support leg 501 on the vibration amplitude of the test bench 101. Furthermore, in order to improve the stability of the test bench 101 during vibration, the support and guidance of the guide rod 502 by the sleeve 503 can control the vibration of the test bench 101 within a certain range.

[0057] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments:

[0058] The working state is as follows: The sealing strip 105 to be tested is assembled onto the contour sheet metal 104, and then fixed inside the vise 103 along with the sealing strip 105, ensuring that the height of the sealing strip 105 in each vise 103 is consistent. The glass 206 is installed at the bottom of the spindle 201 by the suction cup 205, and then the electric cylinder 304 is extended to raise the lifting rod 305 until the top plane of the T-shaped frame 307 is aligned with the height of the sealing strip 105. This then activates the lifting slide 302 on the gantry 301 and drives the reduction motor 20. 2. The glass 206 descends, thus synchronously driving the main shaft 201, side arm 203, H bracket 204, suction cup 205 and glass 206 to descend. When the glass 206 descends and begins to press down on the top plane of the T-shaped frame 307, the pressure of the glass 206 pressing down can be measured by the pressure sensor 306 through the force transmission. Thus, the operator can observe the pressure on the sealing strip 105 from the control panel. After obtaining the required pressure, the lifting slide 302 locks the height, and the electric cylinder 304 retracts, causing the lifting rod 305 and T-shaped frame 307 to descend and reset.

[0059] Furthermore, the geared motor 202 drives the main shaft 201 to rotate, thereby, with the support of the bearing seat 303, the two glass pieces 206 are rotated through the side arm 203 and the H bracket 204. In this way, the sealing strip 105 can be subjected to a sliding durability test while the sealing strip 105 remains stationary.

[0060] Furthermore, since the glass 206 is rotating, the linear velocities of the inner and outer sides of the natural circular motion are inconsistent, resulting in different sliding conditions between the inner and outer ends of the sealing strip 105 and the glass 206. This leads to inconsistent test conditions. Therefore, the dual-shaft extension motor 110 drives the second sprocket 112 to rotate slowly through the one-way bearing 111, which in turn drives the first sprocket 108 to rotate through the chain 109. Supported by the bearing seat 107, the first sprocket 108 drives the vise 103 on the turntable 102 to rotate through the secondary shaft 106, ultimately causing the sealing strip 105 to rotate. This causes the end of the sealing strip 105 near the center of the test bench 101 to exchange positions with the end near the edge of the test bench 101, thus making the sliding conditions between the inner and outer ends of the sealing strip 105 and the glass 206 consistent.

[0061] Conversely, the above structural features can also be used to test the sliding durability of the same sealing strip 105 at different speeds and frequencies.

[0062] Furthermore, when the dual-shaft extension motor 110 reverses at high speed, due to the effect of the one-way bearing 111, the dual-shaft extension motor 110 will not be able to drive the sprocket 112 to rotate in the opposite direction. Instead, due to the instability of the rapid rotation of the eccentric wheel 113, the test bench 101 will vibrate, thus making the sliding between the sealing strip 105 and the glass 206 in a vibrating environment. This simulates the bumps of a car and the resonance of the car body when the engine is running. During vibration, the vibration transmission between the test bench 101 and the support leg 501 is reduced by the spring 504. Conversely, it can also be seen that when the test bench 101 is connected to the ground by the support leg 501, the spring 504 can reduce the limitation of the fixed support leg 501 on the vibration amplitude of the test bench 101. Furthermore, in order to improve the stability of the test bench 101 during vibration, the support and guidance of the guide rod 502 by the sleeve 503 can control the vibration of the test bench 101 within a certain range.

[0063] Furthermore, the temperature sensor 404 monitors the temperature inside the protective cylinder 402 heated by the electric heater 403, thereby simulating different ambient temperatures. At the same time, since the glass 206 is in a rotating state, the strong swinging and the interaction force between it and the sealing strip 105 make the glass 206 potentially breakable. The cooperation between the protective cover 401 and the protective cylinder 402 protects the safety of the test personnel.

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

[0065] Furthermore, if a whole circular piece of glass 206 is selected as the test object, it can be stabilized by the suction cups 205 on both sides. In this way, when it is pressed down and rotated, it will always maintain contact with the sealing strip 105, thereby simulating the situation when the glass 206 is half open in the car window, that is, the bottom part is always pressing the sealing strip 105.

[0066] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
