Description

Technical Field

[0001] The utility model relates to the technical field of testing of anti-pinch finger functions, in particular to an anti-pinch testing device. Background Art

[0002] The car window is opened and closed by lifting the window glass. When the car window is closed, if a person's fingers, arms, etc. are between the window glass and the window frame, the upward moving window glass will trap the person's fingers and arms, which may cause damage to the person's fingers and arms. The window glass of existing vehicles is generally equipped with an anti-pinch function, that is, during the process of closing the window, if the upward moving window glass is blocked by fingers, arms (or other objects), it will stop moving upward or move downward to avoid causing damage to fingers and arms.

[0003] Before the automobile window glass is applied to the vehicle, its anti-pinch function needs to be tested in order to obtain the magnitude of the resistance force required to stop the window glass from moving. The magnitude of the resistance force to stop the window glass from moving needs to be within a set range to avoid the actual resistance force being too large, which may still cause certain injuries to fingers and arms in actual application, and to avoid the actual resistance force being too small, which may cause the window glass to be easily disturbed by external forces when closing, thereby hindering the closing process of the window.

[0004] However, the prior art lacks a simple and convenient device for automatically testing the anti-pinch function of vehicle window glass. Utility Model Content

[0005] One of the purposes of the utility model is to provide an anti-pinch test device to solve the technical problem of the prior art that there is a lack of a device for automatically testing the anti-pinch function of a vehicle window glass.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An anti-pinch test device comprises a first drive mechanism, a test base and a test terminal; the test terminal is mounted on the test base and can move along a first direction on the test base; the test terminal has a first contact portion and a second contact portion for connecting with a measured object, the first contact portion and the second contact portion are respectively used to contact the front and side surfaces of the measured object; the first drive mechanism is connected to the test base and applies a force to the test base in a second direction, the second direction being different from the first direction.

[0008] According to the above technical solution, the anti-pinch test device includes a first driving mechanism, a test base and a test terminal, and a first contact portion and a second contact portion are arranged on the test terminal; force is applied by the first driving mechanism to generate pressure between the second contact portion of the test terminal and the side of the object to be measured, and static friction force is formed based on the pressure; and by adjusting the magnitude of the force applied by the first driving mechanism, the value of the static friction force between the second contact portion of the test terminal and the object to be measured is controlled. When the static friction between the second contact portion of the test terminal and the object to be measured is set to a certain reference value, the object to be measured is controlled to move normally in the first direction. If the speed of the translation of the object to be measured is 0 under the specific static friction, that is, it cannot move in the first direction, it means that during the translation of the object to be measured, if a person's finger, arm or other object is on its moving path, the object to be measured can stop the translation when the person's finger, arm or other object is clamped by the object to be measured, thereby reducing and lowering the damage to the person's finger, arm or other object. Therefore, it can be confirmed that the anti-pinch finger function of the object to be measured meets the requirements; and if the speed of the translation of the object to be measured slows down under the specific static friction, but it can still maintain the translation, it means that during the translation of the object to be measured, if a person's finger, arm or other object is on its moving path, the object to be measured cannot stop the translation when the person's finger, arm or other object is clamped by the object to be measured, which will further squeeze the person's finger, arm or other object, causing significant damage to the person's finger, arm or other object. Therefore, it can be confirmed that the anti-pinch finger function of the object to be measured does not meet the requirements.

[0009] Furthermore, the first direction is perpendicular to the second direction.

[0010] According to the above technical solution, the second direction is set to be perpendicular to the first direction, that is, the direction of the force applied by the first driving mechanism is perpendicular to the direction of the translational movement of the object under test. In this way, the first driving mechanism will not generate any force acting on the object under test in the first direction except for the static friction force generated between the object under test and the second contact portion of the test terminal, so that the force applied to the object under test during the translational movement is simple, and the magnitude of the force applied by the object under test during the translational movement can be determined more clearly and accurately, that is, the result of the test of the anti-pinch function of the object under test will be more accurate.

[0011] Furthermore, the first driving mechanism is a motor or a cylinder or a hydraulic cylinder.

[0012] According to the above technical solution, the type of the first driving mechanism is not limited, and it can be arbitrarily selected as a motor, or a cylinder, or a hydraulic cylinder.

[0013] Furthermore, the test terminal is connected to the test base in a sliding manner or a rolling manner.

[0014] According to the above technical solution, the implementation method of the relative movement between the test terminal and the test base along the first direction is not limited. When the two are connected by sliding, the structure connecting the two is, for example, a slider, a slide rail, or a slider, a slide groove, etc. When the two are connected by rolling, the structure connecting the two is, for example, a roller, a limit groove, etc.

[0015] Furthermore, the test terminal includes a U-shaped groove portion, a groove bottom of the U-shaped groove portion is the first contact portion, and a side wall of the U-shaped groove portion is the second contact portion.

[0016] According to the above technical solution, the U-shaped groove is used as a basis, and the first contact portion and the second contact portion are arranged thereon respectively. The structure is simple, easy to process and prepare, and the stability when connected and matched with the measured object S is higher.

[0017] Furthermore, the friction coefficient between the second contact portion and the side surface of the measured object is greater than a set value.

[0018] According to the above technical solution, when the friction coefficient between the second contact portion and the side surface of the measured object is large, a large static friction force can be formed between the two when the extrusion force is constant or small, so that the first driving mechanism does not need to output a large force, which can reduce the requirements for the output force of the first driving mechanism. The first driving mechanism can select a driving mechanism such as a motor, cylinder, hydraulic cylinder, etc. with lower specifications and lower costs.

[0019] Furthermore, the anti-pinch testing device also includes a friction plate, and the friction plate is used to be fixed on the side of the object to be tested.

[0020] According to the above technical solution, by arranging a friction plate on the side of the object to be measured, the friction coefficient and static friction force between the object to be measured and the second contact portion of the test terminal can be increased. For the first driving mechanism, it does not need to output a large force to generate sufficient static friction force between the object to be measured and the second contact portion of the test terminal. In this way, the requirements for the output force of the first driving mechanism can be reduced, and the first driving mechanism can select a driving mechanism such as a motor, cylinder, hydraulic cylinder, etc. with lower specifications and lower costs.

[0021] Furthermore, the anti-pinch test device also includes a lifting screw, and the test base and the first driving mechanism are arranged on the lifting screw.

[0022] According to the above technical solution, by setting a lifting screw, the height of the test base and the first driving mechanism can be adjusted to meet the needs of testing the anti-pinch performance of objects of different types, specifications and heights.

[0023] Furthermore, the anti-pinch testing device also includes a mounting platform, and the lifting screw is mounted on the mounting platform and can rise or fall in a vertical direction relative to the mounting platform.

[0024] According to the above technical solution, the lifting screw can be installed and fixed by setting up a mounting platform.

[0025] Furthermore, a bolt positioning portion is provided at the lower end of the mounting platform, and the bolt positioning portion is used to fix the mounting platform on the ground.

[0026] According to the above technical solution, the bolt positioning part can be specifically a bolt hole. By providing the bolt positioning part, the mounting platform can be fixed to the ground by bolts through screw connection. When the position of the mounting platform needs to be adjusted, it is only necessary to remove the bolts on the bolt positioning part.

[0027] Beneficial effects of the utility model:

[0028] The utility model provides an anti-pinch test device, which comprises a first driving mechanism, a test base and a test terminal, and a first contact portion and a second contact portion are arranged on the test terminal; a force is applied by the first driving mechanism to generate pressure between the second contact portion of the test terminal and the side of the object to be tested, and a static friction force is formed based on the pressure; and the value of the static friction force between the second contact portion of the test terminal and the object to be tested is controlled by adjusting the magnitude of the force applied by the first driving mechanism. When the static friction between the second contact portion of the test terminal and the object to be measured is set to a certain reference value, the object to be measured is controlled to move normally in the first direction. If the speed of the translation of the object to be measured is 0 under the specific static friction, that is, it cannot move in the first direction, it means that during the translation of the object to be measured, if a person's finger, arm or other object is on its moving path, the object to be measured can stop the translation when the person's finger, arm or other object is clamped by the object to be measured, thereby reducing and lowering the damage to the person's finger, arm or other object. Therefore, it can be confirmed that the anti-pinch finger function of the object to be measured meets the requirements; and if the speed of the translation of the object to be measured slows down under the specific static friction, but it can still maintain the translation, it means that during the translation of the object to be measured, if a person's finger, arm or other object is on its moving path, the object to be measured cannot stop the translation when the person's finger, arm or other object is clamped by the object to be measured, which will further squeeze the person's finger, arm or other object, causing significant damage to the person's finger, arm or other object. Therefore, it can be confirmed that the anti-pinch finger function of the object to be measured does not meet the requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0040] In one embodiment of the anti-pinch test device provided by the utility model, the anti-pinch test device is used to test the anti-pinch function of the object being tested. Figure 1 to Figure 3As shown, the anti-pinch test device includes a first driving mechanism 10, a test base 20 and a test terminal 30; the test terminal 30 is installed on the test base 20, and the test terminal 30 can move along a first direction on the test base 20; the test terminal 30 has a first contact portion 31 and a second contact portion 32 for connecting with the object S to be tested, and the first contact portion 31 and the second contact portion 32 are respectively used to contact the front and side of the object S to be tested; the first driving mechanism 10 is connected to the test base 20, and applies a force to the test base 20 in a second direction, and the second direction is different from the first direction.

[0041] In this embodiment, the object S to be measured can be a car window glass, or other objects or structures similar to car window glass. As the object S to be measured, it has the following elements, namely: first, it can move horizontally, such as lifting and lowering in the vertical direction or translating in the horizontal direction; second, human fingers, arms or other objects may appear on its moving path, and there is a risk of human fingers, arms or other objects being caught and injured. According to the scope defined by the above elements, the object S to be measured can be understood as an opening and closing component that moves horizontally in a device or system that realizes opening and closing by translation. For example, a rolling shutter door structure can be used as the above-mentioned object to be measured. Although the rolling shutter door rolls up the door body together during the closing process and unrolls the door body during the opening process, the outer end of the door body extends outward (opens) and retracts inward (closes) during the above-mentioned rolling and unrolling process, which is a translational motion form, which meets the element definition of the above-mentioned object S to be measured.

[0042] For the object S to be measured, its front side refers to the side in the translational direction. If there are human fingers, arms or other objects in the moving path of the object S to be measured, then when the object S to be measured moves, the front side of the object S to be measured will contact and resist the human fingers, arms or other objects. The side of the object S to be measured refers to the side adjacent to the front side of the object S to be measured, which is not in the translational direction of the object S to be measured, and the straight line direction perpendicular to it is perpendicular to or intersects with the translational direction of the object S to be measured. Taking the window glass as an example, the upper side of the window glass (with the window glass mounted on the vehicle as a reference) is the front side of the object S to be measured, while the inner and outer sides (with the window glass mounted on the vehicle as a reference) are the side sides of the object S to be measured.

[0043] When testing the anti-pinch function of the object S to be tested, first, the object S to be tested is matched with the anti-pinch test device, which specifically includes: docking the test terminal 30 with the object S to be tested, so that the first contact portion 31 of the test terminal 30 contacts the front of the object S to be tested, and the second contact portion 32 contacts the side of the object S to be tested; and adjusting the translation direction of the object S to be tested to the first direction.

[0044] Afterwards, the object S to be tested is tested in two aspects. First, the lower limit of the force applied during the translation of the object S to be tested (if a person's finger, arm or other object is in the translation path of the object S to be tested, the force received from the object S to be tested when it abuts against the front of the object S to be tested) is tested. Specifically, the first drive mechanism 10 does not apply force to the test base 20. At this time, the test terminal 30 and the test base 20 can move freely relative to each other; and the object S to be tested makes normal translation. In this case, if the test terminal 30 is pushed by the object S to be tested due to the abutment of the first contact portion 31 with the object S to be tested, and moves synchronously with the object S to be tested, it means that the lower limit of the force applied during the translation of the object S to be tested meets the requirements. During the translation of the object S to be tested, the test terminal 30 moves synchronously with the object S to be tested; and the test base 20 is not affected by the translation of the object S to be tested, and relative movement occurs between the test terminal 30 and the test base 20. If the front side of the object S cannot push the test terminal 30 to move synchronously when it contacts the first contact portion 31 , it means that the force applied by the translation of the object S is too small, below the lower limit, and does not meet the requirements.

[0045] Secondly, the upper limit of the force applied during the translation of the object S to be tested (if a person's finger, arm or other object is in the translation path of the object S to be tested, the force received from the object S to be tested when it contacts the front of the object S to be tested) is tested. Specifically, the first driving mechanism 10 applies a force to the test base 20, and the force is transmitted to the test terminal 30 through the test base 20 and acts between the second contact portion 32 of the test terminal 30 and the object S to be tested; while the object S to be tested performs normal translation.

[0046] During the test, the force applied by the first drive mechanism 10 to the test base 20 and the test terminal 30 makes the test terminal 30 no longer able to move freely relative to the test base 20 (completely unable to move or the speed of movement is reduced). As for the second contact portion 32 of the test terminal 30 and the object S to be tested, the force applied by the first drive mechanism 10 generates an extrusion force between the second contact portion 32 of the test terminal 30 and the object S to be tested, and forms a static friction force based on the extrusion force, which forms an obstacle to the normal translation process of the object S to be tested. In addition, the static friction force between the second contact portion 32 of the test terminal 30 and the object S to be tested is positively correlated with the extrusion force between the two, and is also positively correlated with the force applied by the first drive mechanism 10. Therefore, by adjusting the magnitude of the force applied by the first drive mechanism 10, the static friction force between the second contact portion 32 of the test terminal 30 and the object S to be tested can be controlled.

[0047] During the above test, the magnitude of the force applied by the first drive mechanism 10 can be gradually increased in stages. For example, in the first stage, the force output by the first drive mechanism 10 is the initial value, at which time a static friction force is generated between the second contact portion 32 of the test terminal 30 and the object S to be tested, and the static friction force forms an obstacle to the normal translation of the object S to be tested. Under this obstacle, the translation speed of the object S to be tested will be slowed down. However, if the object S to be tested can still translate along the first direction, it indicates that the force applied during the translation of the object S to be tested is greater than the static friction force generated between the second contact portion 32 of the test terminal 30 and the object S to be tested in the first stage. Afterwards, in the second stage, the second driving mechanism 10 outputs a force greater than the initial value, so that a greater static friction force can be generated between the second contact portion 32 of the test terminal 30 and the object S to be measured; if under the greater static friction force, the speed of the translation of the object S to be measured slows down to 0, that is, the object S to be measured no longer translates along the first direction, then it indicates that the force applied during the translation of the object S to be measured is equal to or less than the static friction force generated between the second contact portion 32 of the test terminal 30 and the object S to be measured in the second stage. The static friction force generated between the second contact portion 32 of the test terminal 30 and the object S to be measured in the second stage can be regarded as the force applied during the translation of the object S to be measured (if necessary, more tests can be performed to change the magnitude of the force output by the first drive mechanism 10, and finally obtain a more accurate value of the force applied during the translation of the object S to be measured). If the static friction force generated between the second contact portion 32 of the test terminal 30 and the object S to be measured in the second stage is less than the preset standard value or interval range, it indicates that the upper limit of the force applied during the translation of the object S to be measured meets the requirements, that is, it means that during the translation of the object S to be measured, if a person's fingers, arms or other objects are in its moving path, the object S to be measured can stop the translation when the person's fingers, arms or other objects are clamped by the object S to be measured, thereby reducing and minimizing the damage to the person's fingers, arms or other objects. If, under the greater static friction force, the speed of the measured object S's translation is further slowed down, but it can still translate along the first direction, it means that the force applied during the translation of the measured object S is still greater than the static friction force generated between the second contact portion 32 of the test terminal 30 and the measured object S in the second stage. In this way, the magnitude of the force output by the second driving mechanism 10 is further increased in the third stage.

[0048] Of course, during the above test, the force applied by the first driving mechanism 10 can also be directly controlled to be a size corresponding to a preset standard value or interval range. In this case, if the speed of the measured object S is slowed down to 0, that is, the measured object S no longer moves in the first direction, it means that the force applied during the translation of the measured object S is equal to or less than the static friction force generated between the second contact portion 32 of the test terminal 30 and the measured object S, and of course, it is also less than the preset standard value or interval range, and the upper limit of the force applied during the translation of the measured object S meets the requirements. That is to say, during the translation of the measured object S, if a person's finger, arm or other object is in its moving path, the measured object S can stop the translation when the person's finger, arm or other object is clamped by the measured object S, thereby reducing and lowering the damage to the person's finger, arm or other object. On the contrary, if the speed of the measured object S translation slows down, but it can still translate along the first direction, it means that the force applied during the translation of the measured object S is greater than the static friction force generated between the second contact portion 32 of the test terminal 30 and the measured object S. This means that the force applied during the translation of the measured object S is greater than the static friction force generated between the second contact portion 32 of the test terminal 30 and the measured object S. Of course, it is also greater than the preset standard value or interval range, and the upper limit of the force applied during the translation of the measured object S exceeds the requirement. It also means that during the translation of the measured object S, if a person's finger, arm or other object is in its moving path, the measured object S cannot stop the translation when the person's finger, arm or other object is clamped by the measured object S, which will further squeeze the person's finger, arm or other object, causing significant damage to the person's finger, arm or other object.

[0049] In the above test process, the purpose of the second test item is to test the anti-pinch function of the object S under test, while the purpose of the first test item is not to test the anti-pinch function of the object S under test, but it is the premise and basis for testing the anti-pinch function of the object S under test. Moreover, the first test item will have a certain impact on the second test item, which is mainly manifested in the second test item that when the first direction, that is, the translation direction of the object S under test is a non-horizontal direction such as a vertical direction or an inclined direction, part of the force applied during the translation of the object S under test acts on the static friction between the second contact portion 32 and the object S under test, and the other part acts on the gravity of the first contact portion 31 and the test terminal 30; that is, it is manifested as the following relationship:

[0050] F1=F2+F3

[0051] Among them, F1 is the force applied during the translation of the object S under test, F2 is the static friction between the second contact portion 32 and the object S under test, and F3 is the component of the gravity of the test terminal 30 in the first direction (when the first direction is a vertical direction, F3 is equal to the total gravity of the test terminal 30, and when the first direction is an inclined direction, F3 is less than the gravity of the test terminal 30).

[0052] According to the above relationship, when the weight of the test terminal 30 is large, the part of the gravity of the force applied during the translation of the object S under test acting on the test terminal 30 will be relatively large, so the error in characterizing and calibrating the force applied during the translation of the object S under test by the static friction between the second contact portion 32 and the object S under test (or the pressure between the second contact portion 32 and the object S under test, that is, the force applied by the first drive structure 10 to the test base 20 and the test terminal 30) will be relatively large. Therefore, in actual implementation, the weight of the test terminal 30 can be set to be relatively small to minimize the above error. Or in actual implementation, the first direction is set in the horizontal direction, that is, the translation direction of the object S under test is set in the horizontal direction.

[0053] In one embodiment of the anti-pinch testing device, the first direction is perpendicular to the second direction.

[0054] In this embodiment, the second direction is set to be perpendicular to the first direction, that is, the direction of the force applied by the first driving mechanism 10 is perpendicular to the direction of the translation of the object S under test. In this way, the first driving mechanism 10 does not generate any force acting on the object S under test in the first direction except for the static friction force generated between the object S under test and the second contact portion 32 of the test terminal 30. This makes the force applied to the object S under test during the translation process simple, and the magnitude of the force applied by the object S under test during the translation process can be determined more clearly and accurately, that is, the test result of the anti-pinch function of the object S under test will be more accurate.

[0055] In one embodiment of the anti-pinch testing device, the first driving mechanism 10 is a motor or a cylinder or a hydraulic cylinder.

[0056] In this embodiment, the type of the first driving mechanism 10 is not limited, and it can be arbitrarily selected as a motor, a pneumatic cylinder, or a hydraulic cylinder.

[0057] Specifically, when the first driving mechanism 10 is a motor, it can be selected as a telescopic motor, which can be telescopic, and the telescopic state is determined by the power-on state of the motor. When the motor is powered on, the output end of the motor overcomes the elastic force of the elastic member arranged inside it and is in a retracted state, and when not powered on, the output end of the motor is in an extended state under the elastic force of the elastic member. When the motor is in an extended state, the output end of the motor drives the test base 20 to extend synchronously, and at this time, the test base 20 and the test terminal 30 are not subjected to force on each other, and when the motor is in a retracted state, the output end of the motor drags and pulls the test base 20, and at this time, the test base 20 also drags and pulls the test terminal 30, and there will be a mutual force between the test base 20 and the test terminal 30, and correspondingly, a mutual squeezing force will be generated between the second contact portion 32 of the test terminal 30 and the object S to be tested. The timing of controlling the power-on state of the motor may be based on whether the object S to be measured enters the anti-pinch interval. When the object S to be measured moves along the first direction to the anti-pinch interval, the motor is powered on, and the motor is not powered on outside the anti-pinch interval.

[0058] In one embodiment of the anti-pinch test device, the test terminal 30 is connected to the test base 20 by sliding or rolling.

[0059] In this embodiment, the implementation method of the relative movement between the test terminal 30 and the test base 20 along the first direction is not limited. When the two are connected by sliding, the structure connecting the two is, for example, a slider, a slide rail, or a slider, a slide groove, etc. When the two are connected by rolling, the structure connecting the two is, for example, a roller, a limit groove, etc.

[0060] In one embodiment of the anti-pinch test device, the test terminal 30 includes a U-shaped groove portion 33 , the bottom of the U-shaped groove portion is the first contact portion 31 , and the side wall of the U-shaped groove portion is the second contact portion 32 .

[0061] In this embodiment, the U-shaped groove 33 is used as a basis, and the first contact portion 31 and the second contact portion 32 are arranged thereon respectively. The structure is simple, easy to process and prepare, and the stability when connected and matched with the measured object S is higher.

[0062] In one embodiment of the anti-pinch testing device, the friction coefficient between the second contact portion 32 and the side surface of the object S to be tested is greater than a set value.

[0063] In this embodiment, taking the window glass as an example, the material of the side of the object S to be tested is glass. In this case, the material of the second contact portion 32 of the test terminal 30 can be selected as a material with a large friction coefficient with the glass. When the friction coefficient between the second contact portion 32 and the side of the object S to be tested is large, a large static friction force can be formed between the two when the extrusion force is constant or small, so that the first drive mechanism 10 does not need to output a large force, which can reduce the requirements for the output force of the first drive mechanism 10, and the first drive mechanism 10 can select a motor, cylinder, hydraulic cylinder or other drive mechanism with lower specifications and lower costs.

[0064] In one embodiment of the anti-pinch testing device, the anti-pinch testing device further comprises a friction plate, and the friction plate is used to be fixed on the side of the object S to be tested.

[0065] In this embodiment, by providing a friction plate on the side of the object S to be measured, the friction coefficient and the static friction force between the object S to be measured and the second contact portion 32 of the test terminal 30 can be increased. For the first driving mechanism 10, it is not necessary to output a large force to generate sufficient static friction force between the object S to be measured and the second contact portion 32 of the test terminal 30. In this way, the requirements for the output force of the first driving mechanism 10 can be reduced. The first driving mechanism 10 can select a driving mechanism such as a motor, cylinder, hydraulic cylinder, etc. with lower specifications and lower costs.

[0066] In an embodiment of the anti-pinch test device, the anti-pinch test device further includes a lifting screw 40 , and the test base 20 and the first driving mechanism 10 are disposed on the lifting screw 40 .

[0067] In this embodiment, by providing a lifting screw 40, the height of the test base 20 and the first driving mechanism 10 can be adjusted to meet the needs of testing the anti-pinch performance of objects S of different types, specifications and heights.

[0068] Specifically, the height adjustment of the lifting screw 40 can be controlled by components such as a knob.

[0069] In one embodiment of the anti-pinch testing device, the anti-pinch testing device further comprises a mounting platform 50 , and the lifting screw 40 is mounted on the mounting platform 50 and can rise or fall in a vertical direction relative to the mounting platform 50 .

[0070] In this embodiment, the lifting screw 40 can be installed and fixed by providing the installation platform 50 .

[0071] In one embodiment of the anti-pinch testing device, a bolt positioning portion is provided at the lower end of the mounting platform 50, and the bolt positioning portion is used to fix the mounting platform on the ground.

[0072] In this embodiment, the bolt positioning portion can be specifically a bolt hole. By providing the bolt positioning portion, the mounting platform 50 can be fixed to the ground by bolts through screw connection. When the position of the mounting platform 50 needs to be adjusted, it is only necessary to remove the bolts on the bolt positioning portion.

[0073] In summary, the anti-pinch test device provided by the above-mentioned embodiment of the utility model includes a first driving mechanism 10, a test base 20 and a test terminal 30, and a first contact portion 31 and a second contact portion 32 are arranged on the test terminal 30; a force is applied by the first driving mechanism 10 to generate pressure between the second contact portion 32 of the test terminal 30 and the side of the object S to be measured, and a static friction force is formed based on the pressure; and, by adjusting the magnitude of the force applied by the first driving mechanism 10, the value of the static friction force between the second contact portion 32 of the test terminal 30 and the object S to be measured is controlled. When the static friction between the second contact portion 32 of the test terminal 30 and the object S to be tested is set to a certain reference value, the object S to be tested is controlled to move normally in the first direction. If the speed of the object S to be tested is 0 under the specific static friction, that is, it cannot move in the first direction, it means that during the translation of the object S to be tested, if a person's finger, arm or other object is in its moving path, the object S to be tested can stop the translation when the person's finger, arm or other object is clamped by the object S to be tested, thereby reducing and minimizing the damage to the person's finger, arm or other object. It is confirmed that the anti-pinch function of the measured object S meets the requirements; if the speed of the measured object S's translational movement slows down under the specific static friction force, but it can still maintain translational movement, it means that during the translational movement of the measured object S, if a person's fingers, arms or other objects are in its moving path, the measured object S cannot stop the translational movement when the person's fingers, arms or other objects are clamped by the measured object S, which will further squeeze the person's fingers, arms or other objects, causing significant damage to the person's fingers, arms or other objects. Therefore, it can be confirmed that the anti-pinch function of the measured object S does not meet the requirements.

[0074] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
