Description

Technical Field

[0001] This invention relates to the field of automotive testing technology, and in particular to an opening and closing durability test bench for electric sliding doors of automobiles. Background Technology

[0002] Sliding doors are widely used in various vehicle types, including MPVs (Multi-Purpose Vehicles). They are mainly divided into manual and electric sliding doors based on their drive type. The testing methods for the opening and closing durability of these two types of sliding doors differ. Electric sliding doors, in addition to normal opening and closing, must be tested for front-end anti-pinch and rear-end jamming to protect passengers and the door's mechanics. Furthermore, the testing of electric sliding doors also includes uphill and downhill scenarios. However, existing automotive electric sliding door opening and closing durability testing devices cannot adequately address these issues.

[0003] Therefore, existing electric sliding door opening and closing durability testing devices cannot effectively test the front anti-pinch, rear anti-spinning, and performance of electric sliding doors in uphill and downhill conditions. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing electric sliding door opening and closing durability testing devices cannot effectively test the front anti-pinch, rear anti-spinning, and performance of electric sliding doors in uphill and downhill conditions.

[0005] To address the aforementioned problems, one embodiment of the present invention provides an opening and closing durability test bench for electric sliding doors of automobiles, including an anti-pinch device and / or a stall device. The anti-pinch device includes an anti-pinch frame and an anti-pinch component; the anti-pinch component includes a first telescopic assembly and an anti-pinch force detection assembly. The first telescopic assembly is disposed on the anti-pinch frame, and the anti-pinch force detection assembly is disposed on the output end of the first telescopic assembly. Furthermore, the first telescopic assembly can drive the anti-pinch force detection assembly to be extended or retracted relative to the electric sliding door under test along the width direction of the anti-pinch frame, thereby detecting the anti-pinch force of the electric sliding door under test.

[0006] The stall device includes a stall frame and a stall component. The stall component includes a second telescopic assembly and a stall force detection assembly. One end of the second telescopic assembly is rotatably connected to the stall frame, and the stall force detection assembly is located on the output end of the second telescopic assembly. Furthermore, the second telescopic assembly drives the stall force detection assembly to be in an extended or retracted state relative to the electric sliding door under test along the length of the stall frame, in order to detect the stall force of the electric sliding door under test.

[0007] Using the above technical solution, the anti-pinch frame supports the anti-pinch components. The first telescopic component extends or retracts the anti-pinch force detection component relative to the electric sliding door under test along the width of the anti-pinch frame. The anti-pinch force detection component detects the lateral anti-pinch force of the electric sliding door. The stall frame supports the stall component. The second telescopic component extends or retracts the stall force detection component relative to the electric sliding door under test along the length of the stall frame. The stall force detection component detects the stall force of the electric sliding door. Therefore, this automotive electric sliding door opening and closing durability test bench can effectively detect the front-end anti-pinch and rear-end stall performance of the electric sliding door.

[0008] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile. The anti-pinch component further includes an anti-pinch base plate, and the anti-pinch base plate is slidably connected to the anti-pinch frame so that the anti-pinch base plate can slide relative to the anti-pinch frame in the height direction and the width direction of the anti-pinch frame.

[0009] The first telescopic component includes a slide table, a sliding rod, and a first driving component; the slide table is slidably sleeved on the sliding rod, and one side of the slide table is fixedly connected to the side of the anti-pinch base plate away from the anti-pinch frame; one end of the sliding rod is connected to the output end of the first driving component, and the other end is connected to the anti-pinch force detection component.

[0010] Using the above technical solution, the first driving component can drive the sliding rod to slide relative to the sliding table, thereby causing the anti-pinch force detection component located at the other end of the sliding rod to be in an extended or retracted state relative to the electric sliding door under test along the width direction of the anti-pinch frame, thus completing the detection of the anti-pinch force. Compared to not setting a sliding table, the sliding table is slidably sleeved on the sliding rod, and one side of the sliding table is fixedly connected to the anti-pinch base plate, which can support the sliding rod to ensure the stability of the sliding rod connection. The anti-pinch base plate is slidably connected to the anti-pinch frame, which allows the anti-pinch component to slide relative to the anti-pinch frame in the height and width directions of the anti-pinch frame. This facilitates the adjustment of the position of the anti-pinch component by the anti-pinch device, thereby enabling the anti-pinch device to detect the anti-pinch force of electric sliding doors of different sizes, improving the convenience of using the opening and closing durability test bench for electric sliding doors.

[0011] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile. The anti-pinch force detection assembly includes an anti-pinch force detection element and a stop. The sliding rod includes two rod portions, a first connecting portion, and a second connecting portion. Two through holes are provided on the sliding platform, and the sliding platform is sleeved on the two rod portions through the two through holes. The first driving element is configured as a first cylinder. One side of the first connecting portion is fixedly connected to one end of the two rod portions, and the other side is connected to the output end of the first cylinder through a floating joint. One side of the second connecting portion is fixedly connected to the other end of the two rod portions, and the other side is fixedly connected to one end of the anti-pinch force detection element, the other end of which is fixedly connected to the stop.

[0012] By adopting the above technical solution, the connection between the sliding rod and the anti-pinch force detection component via the second connecting part increases the connection surface between the sliding rod and the anti-pinch force detection component, thereby strengthening the stability of the connection between them. The stop head protects the anti-pinch force detection component, preventing damage caused by the electric sliding door directly applying force to it. Compared to having only one rod, the connection between the first and second connecting parts increases the stability of the connection. The connection between the sliding rod and the first cylinder via the first connecting part increases the connection surface between them, further strengthening the stability of the connection. Furthermore, the first connecting part connects to the output end of the first cylinder via a floating joint, increasing the ease of installation and connection while eliminating errors during installation and connection, thus improving the accuracy of the opening and closing durability test of the electric sliding door. Compared to other driving components, setting the first driving component as the first cylinder can enhance the adaptability of the first driving component to the environment, thereby avoiding the impact of environmental changes on the first driving component under different temperatures, humidity and other conditions, which in turn affects the test results, thereby further improving the accuracy of the opening and closing durability test bench for the electric sliding door of the car.

[0013] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile. The stall component further includes a stall base plate, which is slidably connected to a stall frame, allowing the stall base plate to slide relative to the stall frame in the height and width directions of the stall frame. The second telescopic component includes a mounting plate and a second drive member; one end of the mounting plate is rotatably connected to the stall base plate about an axis in the height direction of the stall frame, and a fastener is provided between the mounting plate and the stall base plate to lock the position of the mounting plate relative to the stall base plate. The second drive member is fixedly connected to the side of the mounting plate away from the stall base plate, and a stall force detection component is disposed on the output end of the second drive member.

[0014] Using the above technical solution, the second driving component can drive the stall detection assembly to be in an extended or retracted state relative to the electric sliding door under test along the length direction of the stall frame, thereby completing the detection of stall force. Since the electric sliding door rotates a certain angle around the height direction of the stall frame during opening and closing, one end of the mounting plate is rotatably connected to the stall base plate around an axis in the height direction of the stall frame. This allows the stall device to adjust the angle of the stall component according to different angles around the height direction of the stall frame during opening or closing, thus detecting the stall force of the electric sliding door at different positions. The stall base plate is slidably connected to the stall frame, allowing the stall base plate to drive the stall component to slide relative to the stall frame in both the height and width directions of the stall frame. This facilitates the stall device adjusting the position of the stall component, enabling it to detect the stall force of electric sliding doors of different sizes, improving the convenience of using the electric sliding door opening and closing durability test bench.

[0015] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile. The stall force detection assembly includes a stall force detection element and a rubber cap. The second drive element is configured as a second cylinder. Both ends of the stall force detection element are connected to the output end of the second cylinder and the rubber cap, respectively, via adapters. One end of the mounting plate is rotatably connected to the stall base plate via a hinge. The fasteners include a snap-fit ​​head disposed on one of the mounting plate and the stall base plate, a snap-fit ​​seat disposed on the other, and a diagonal brace disposed on the hinge; and the snap-fit ​​head and the snap-fit ​​seat are adapted to each other.

[0016] By adopting the above technical solution, the rubber abutment allows the electric sliding door to apply force to the stall force detection component through the rubber abutment, thus avoiding damage to the stall force detection component caused by the electric sliding door directly applying force to it. Compared to other drive components, setting the second drive component as a second cylinder enhances its environmental adaptability, thereby avoiding the impact of environmental changes on the test results due to variations in temperature and humidity, and further improving the accuracy of the opening and closing durability test bench for the electric sliding door. The adapter joints at both ends of the stall force detection component increase the ease of installation between the two ends of the stall force detection component and the second cylinder and rubber abutment. Compared to other rotating connection methods, the hinge connection simplifies the rotating connection structure between the mounting plate and the stall base plate. The diagonal brace on the hinge prevents the mounting plate from rotating relative to the stall base plate after the angle of the stall component is adjusted. The latch head and latch seat lock the position of the mounting plate relative to the stall base plate.

[0017] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile, wherein both the anti-pinch frame and the stall frame include a base and a support. One end of the support is connected to one side of the base, and the other end extends in a direction perpendicular to the base; and the anti-pinch base plate is slidably connected to the side wall of the support of the anti-pinch frame, and the stall base plate is slidably connected to the side wall of the support of the stall frame.

[0018] By adopting the above technical solution, both the anti-pinch frame and the stall frame include a base and a support, which can make the anti-pinch frame and the stall frame smaller in size, thereby reducing the space occupied by the anti-pinch frame and the stall frame.

[0019] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile. A first support moving assembly is provided on the base of the anti-pinch frame away from the support seat; a second support moving assembly is provided on the base of the stall frame away from the support seat. Both the first and second support moving assemblies include caster wheel components and lifting support legs. The caster wheel component includes a caster wheel and a connecting member.

[0020] In the first support and movement assembly, one end of the connector is connected to one side of the base of the anti-pinch frame, and the other end is rotatably connected to the caster wheel. One end of the lifting support foot is connected to one side of the base of the anti-pinch frame.

[0021] In the second support moving assembly, one end of the connector is connected to one side of the base of the stall frame, and the other end is rotatably connected to the caster wheel. One end of the lifting support foot is connected to one side of the base of the stall frame.

[0022] In both the first and second support moving components, the lifting legs can switch between raised and lowered states. When each lifting leg is in the raised state, its height is higher than the height of the universal wheel component in the corresponding support moving component; when each lifting leg is in the lowered state, its height is lower than the height of the universal wheel component in the corresponding support moving component.

[0023] By adopting the above technical solution, the arrangement of the first and second support moving components facilitates the movement of the anti-pinch frame and the stall frame, thereby increasing the convenience of using the opening and closing durability test bench for electric sliding doors. Furthermore, when it is necessary to move the anti-pinch frame and / or the stall frame, the lifting support leg can be lowered. In this state, the height of the lifting support leg is lower than the height of the universal wheel component in the corresponding support moving component, allowing the anti-pinch frame and / or the stall frame to be moved via the universal wheel component. When it is not necessary to move the anti-pinch frame and / or the stall frame, the lifting support leg can be raised. In this state, the height of the lifting support leg is higher than the height of the universal wheel component in the corresponding support moving component, preventing the anti-pinch frame and / or the stall frame from moving due to accidental contact with the universal wheel component.

[0024] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile. The side walls of the support base of the anti-pinch frame and the support base of the stall frame are each provided with a first sliding groove extending along the height direction of the support base. The anti-pinch base plate and the stall base plate are each provided with a second sliding groove extending along the width direction of the support base. Sliding fasteners are provided between the support base of the anti-pinch frame and the anti-pinch base plate, and between the support base of the stall frame and the stall base plate. The sliding fasteners pass through the first and second sliding grooves and cooperate with them, allowing the anti-pinch base plate to slide relative to the support base of the anti-pinch frame, and the stall base plate to slide relative to the support base of the stall frame, in both the height and width directions of the support base.

[0025] By adopting the above technical solution, the sliding fastener configuration enables sliding between the anti-pinch base plate and the support seat of the anti-pinch frame, and between the locked base plate and the support seat of the locked frame, as well as locking and unlocking between them. Furthermore, compared to other structures, this configuration simplifies the structure between the anti-pinch base plate and the support seat of the anti-pinch frame, and between the locked base plate and the support seat of the locked frame.

[0026] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile. An anti-pinch device is provided with an anti-pinch counterweight component, and a stall device is provided with a stall counterweight component. Both the anti-pinch counterweight component and the stall counterweight component include a counterweight block, a pulley assembly, and a connecting rope. The pulley assembly includes a support and a pulley. One end of the support of the anti-pinch counterweight component is fixedly connected to the anti-pinch frame, and the other end is rotatably connected to the pulley of the anti-pinch counterweight component. One end of the support of the stall counterweight component is fixedly connected to the stall frame, and the other end is rotatably connected to the pulley of the stall counterweight component. One end of the connecting rope passes through the side wall of the pulley and is fixedly connected to the counterweight block, and the other end is fixedly connected to the electric sliding door to be tested.

[0027] Using the above technical solution, the anti-pinch counterweight component can convert the weight of the counterweight into a force along the length of the anti-pinch frame from the electric sliding door toward the anti-pinch frame, simulating the state of the electric sliding door when the car is going downhill. The stall counterweight component can convert the weight of the counterweight into a force along the length of the stall frame from the electric sliding door toward the stall frame, simulating the state of the electric sliding door when the car is going uphill. The setting of the anti-pinch counterweight component and the stall counterweight component facilitates the testing of the anti-pinch force and stall force of the electric sliding door in the opening and closing durability test bench when the car is going uphill or downhill. Furthermore, by adjusting the weight of the counterweight, the slope of the uphill or downhill can also be adjusted, thus facilitating the testing of the electric sliding door's performance under different slopes in the opening and closing durability test bench.

[0028] Another embodiment of the present invention provides an opening and closing durability test bench for an electric sliding door of an automobile. Both the side wall of the support base of the anti-pinch frame and the side wall of the support base of the stall frame are provided with a third sliding groove extending along the height direction of the support base. A protrusion is provided on the counterweight block, which cooperates with the third sliding groove, allowing the counterweight block of the anti-pinch counterweight component to be slidably connected to the side wall of the support base of the anti-pinch frame, and the counterweight block of the stall counterweight component to be slidably connected to the side wall of the support base of the stall frame. A groove is provided on the side wall of the pulley, and one end of the connecting rope passes through the groove of the pulley and is fixedly connected to the counterweight block.

[0029] By employing the above technical solution, the protrusion and the third sliding groove allow the counterweight block of the anti-pinch counterweight component to slide smoothly onto the side wall of the support seat of the anti-pinch frame, and the counterweight block of the stall counterweight component to slide smoothly onto the side wall of the support seat of the stall frame. This prevents the counterweight block from shaking during the movement of the electric sliding door via the connecting rope, thus affecting the test results. The groove on the side wall of the pulley allows the connecting rope to be secured within the groove, preventing it from detaching from the pulley. Therefore, this design increases the accuracy and safety of the opening and closing durability test bench for the electric sliding door.

[0030] The beneficial effects of this invention are:

[0031] The present invention provides an opening and closing durability test bench for electric sliding doors of automobiles, comprising an anti-pinch device and / or a stall device. The anti-pinch device includes an anti-pinch frame and an anti-pinch component; the anti-pinch component includes a first telescopic assembly and an anti-pinch force detection assembly. The first telescopic assembly is disposed on the anti-pinch frame, and the anti-pinch force detection assembly is disposed on the output end of the first telescopic assembly. The anti-pinch frame provides support for the anti-pinch component. The first telescopic assembly drives the anti-pinch force detection assembly to be extended or retracted relative to the electric sliding door under test along the width direction of the anti-pinch frame. The anti-pinch force detection assembly detects the lateral anti-pinch force of the electric sliding door. The stall device includes a stall frame and a stall component. The stall component includes a second telescopic assembly and a stall force detection assembly. One end of the second telescopic assembly is rotatably connected to the stall frame, and the stall force detection assembly is disposed on the output end of the second telescopic assembly. The stall frame provides support for the stall component. The second telescopic assembly drives the stall force detection assembly to be extended or retracted relative to the electric sliding door under test along the length direction of the stall frame. The stall force detection component is used to detect the stall force of the electric sliding door. Therefore, the opening and closing durability test bench for this electric sliding door can effectively detect the front anti-pinch and rear stall performance of the electric sliding door.

[0069] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0070] This embodiment provides an opening and closing durability testing bench for electric sliding doors in automobiles, such as... Figures 1-4 As shown, the device includes an anti-pinch device 10 and / or a stall device 20. The anti-pinch device 10 includes an anti-pinch frame 110 and an anti-pinch component 120. The anti-pinch component 120 includes a first telescopic assembly 121 and an anti-pinch force detection assembly 122. The first telescopic assembly 121 is mounted on the anti-pinch frame 110, and the anti-pinch force detection assembly 122 is mounted on the output end of the first telescopic assembly 121. Furthermore, the first telescopic assembly 121 can drive the anti-pinch force detection assembly 122 to be extended or retracted relative to the electric sliding door under test along the width direction A of the anti-pinch frame 110, in order to detect the anti-pinch force of the electric sliding door under test.

[0071] The stall device 20 includes a stall frame 210 and a stall component 220. The stall component 220 includes a second telescopic assembly 221 and a stall force detection assembly 222. One end of the second telescopic assembly 221 is rotatably connected to the stall frame 210, and the stall force detection assembly 222 is disposed on the output end of the second telescopic assembly 221. Furthermore, the second telescopic assembly 221 drives the stall force detection assembly 222 to be in an extended or retracted state relative to the electric sliding door under test along the length direction B of the stall frame 210, in order to detect the stall force of the electric sliding door under test.

[0072] Specifically, the first telescopic component 121 can be fixedly connected to the anti-pinch frame 110, and the anti-pinch device 10 can detect the anti-pinch force of electric sliding doors of different heights by adjusting the height of the anti-pinch frame 110; the first telescopic component 121 can also be slidably connected to the anti-pinch frame 110, and the anti-pinch force of electric sliding doors of different heights can be detected by adjusting the position of the first telescopic component 121 relative to the anti-pinch frame 110. Preferably, to simplify the structure of the anti-pinch device 10, the first telescopic component 121 in this embodiment is slidably connected to the anti-pinch frame 110, which will be described in detail later and will not be repeated here.

[0073] More specifically, one end of the second telescopic component 221 can be rotatably connected to a fixed position of the blocking frame 210, and the blocking device 20 can detect the blocking force of electric sliding doors of different heights by adjusting the height of the blocking frame 210. Alternatively, one end of the second telescopic component 221 can also be rotatably connected to different positions of the blocking frame 210 by other components, and the position of the second telescopic component 221 relative to the blocking frame 210 can be adjusted by adjusting the position of these other components relative to the blocking frame 210, thereby detecting the blocking force of electric sliding doors of different heights. Preferably, to simplify the structure of the blocking device 20, in this embodiment, the second telescopic component 221 is rotatably connected to the blocking frame 210 by other components, as described later.

[0074] More specifically, the anti-pinch force detection component 122 can be fixedly connected to the output end of the first telescopic component 121 by means of snap-fit, screw connection or other methods. The specific connection can be set according to actual design and usage requirements. This embodiment does not make specific limitations on this.

[0075] More specifically, the stall force detection component 222 can be fixedly connected to the output end of the second telescopic component 221 by means of snap-fit, screw connection or other means. The specific connection can be set according to actual design and usage requirements. This embodiment does not make specific limitations on this.

[0076] More specifically, the opening and closing durability test bench for electric sliding doors of automobiles also includes a control device, which is communicatively connected to the first telescopic component 121, the anti-pinch force detection component 122, the second telescopic component 221, and the stall force detection component 222, respectively, to control the operation of the first telescopic component 121 and the second telescopic component 221, and to receive information detected by the anti-pinch force detection component 122 and the stall force detection component 222.

[0077] It should be noted that the anti-pinch frame 110 supports the anti-pinch component 120. The first telescopic component 121 drives the anti-pinch force detection component 122 to be extended or retracted relative to the electric sliding door under test along the width direction A of the anti-pinch frame 110. The anti-pinch force detection component 122 detects the lateral anti-pinch force of the electric sliding door. The stall frame 210 supports the stall component 220. The second telescopic component 221 drives the stall force detection component 222 to be extended or retracted relative to the electric sliding door under test along the length direction B of the stall frame 210. The stall force detection component 222 detects the stall force of the electric sliding door. Therefore, the opening and closing durability test bench for this electric sliding door can effectively detect the front anti-pinch and rear stall performance of the electric sliding door.

[0078] Another embodiment of this invention provides an opening and closing durability test bench for an electric sliding door of an automobile, such as... Figures 1-3 As shown, the anti-pinch component 120 also includes an anti-pinch base plate 123, which is slidably connected to the anti-pinch frame 110 so that the anti-pinch base plate 123 can slide relative to the anti-pinch frame 110 in the height direction C and the width direction A of the anti-pinch frame 110.

[0079] The first telescopic component 121 includes a slide table 1211, a sliding rod, and a first driving member; the slide table 1211 is slidably sleeved on the sliding rod, and one side of the slide table 1211 is fixedly connected to the side of the anti-pinch base plate 123 away from the anti-pinch frame 110; one end of the sliding rod is connected to the output end of the first driving member, and the other end is connected to the anti-pinch force detection component 122.

[0080] Specifically, the anti-pinch device 10 can be configured by providing two sliding grooves on the anti-pinch frame 110 or the anti-pinch base plate 123, extending respectively along the height direction C and the width direction A of the anti-pinch frame 110. A protrusion adapted to the sliding groove is provided on the anti-pinch base plate 123 or the anti-pinch frame 110, and a locking member is provided between the sliding groove and the protrusion, so that the anti-pinch base plate 123 can slide relative to the anti-pinch frame 110 in the height direction C and the width direction A of the anti-pinch frame 110. Alternatively, sliding grooves can be provided on the anti-pinch frame 110 and the anti-pinch base plate 123, and a sliding fastener can be provided between the sliding grooves, so that the anti-pinch base plate 123 can slide relative to the anti-pinch frame 110 in the height direction C and the width direction A of the anti-pinch frame 110. Preferably, in order to simplify the structure of the anti-pinch component 120, in this embodiment, sliding grooves are provided on the anti-pinch frame 110 and the anti-pinch base plate 123 respectively, and sliding fasteners are provided between the sliding grooves, so that the anti-pinch base plate 123 can slide relative to the anti-pinch frame 110 in the height direction C and the width direction A of the anti-pinch frame 110.

[0081] More specifically, one side of the slide table 1211 can be fixedly connected to the anti-pinch base plate 123 by means of snap-fit, screw-fit, welding, etc. The specific connection can be set according to actual design and usage requirements. This embodiment does not make specific limitations on this.

[0082] More specifically, the shape of the slide 1211 can be set as a cuboid, cube, prism, etc., and its specific shape can be set according to actual design and usage requirements. This embodiment does not make specific limitations in this regard.

[0083] More specifically, one end of the sliding rod can be connected to the output end of the first driving component via a snap-fit, screw connection, or other means. The specific connection method can be determined according to actual design and usage requirements; this embodiment does not impose any specific limitations on this. The specific structure of the sliding rod will be described later and will not be repeated here.

[0084] More specifically, the first driving component can be configured as an electric telescopic rod, a cylinder, or other components. Preferably, in order to reduce the impact of environmental changes on the first driving component, the first driving component in this embodiment is configured as a cylinder.

[0085] It should be noted that the first driving component can drive the sliding rod to slide relative to the sliding table 1211, thereby causing the anti-pinch force detection component 122, which is located at the other end of the sliding rod, to be in an extended or retracted state relative to the electric sliding door to be tested along the width direction A of the anti-pinch frame 110, thus completing the detection of the anti-pinch force. Compared to not having a sliding table 1211, the sliding table 1211 is slidably sleeved on the sliding rod, and one side of the sliding table 1211 is fixedly connected to the anti-pinch base plate 123, which can support the sliding rod to ensure the stability of the sliding rod connection. The anti-pinch base plate 123 is slidably connected to the anti-pinch frame 110, which allows the anti-pinch component 120 to slide relative to the anti-pinch frame 110 in the height direction C and the width direction A of the anti-pinch frame 110. This facilitates the anti-pinch device 10 in adjusting the position of the anti-pinch component 120, thereby enabling the anti-pinch device 10 to detect the anti-pinch force of electric sliding doors of different sizes and improving the convenience of using the opening and closing durability test bench for electric sliding doors.

[0086] Another embodiment of this invention provides an opening and closing durability test bench for an electric sliding door of an automobile, such as... Figures 1-3 As shown, the anti-pinch force detection assembly 122 includes an anti-pinch force detection element 1221 and a stop 1222. The sliding rod includes two rod portions 1212, a first connecting portion 1213, and a second connecting portion 1214. The slide table 1211 has two through holes, and the slide table 1211 is sleeved on the two rod portions 1212 through the two through holes. The first driving element is a first cylinder 1216. One side of the first connecting portion 1213 is fixedly connected to one end of the two rod portions 1212, and the other side is connected to the output end of the first cylinder 1216 through a floating joint 1215. One side of the second connecting portion 1214 is fixedly connected to the other end of the two rod portions 1212, and the other side is fixedly connected to one end of the anti-pinch force detection element 1221. The other end of the anti-pinch force detection element 1221 is fixedly connected to the stop 1222.

[0087] Specifically, the two ends of the two rods 1212 can be fixedly connected to the first connecting part 1213 and the second connecting part 1214 by welding, snap-fitting, screwing or other fixed connection methods. The specific connection method can be set according to the actual design and usage requirements. This embodiment does not make specific limitations on this.

[0088] More specifically, the second connecting part 1214 and the anti-pinch force detection component 1221 can be connected by a detachable fixed connection method such as snap-fit ​​or screw-fit. The specific connection method can be set according to actual design and usage requirements. This embodiment does not make specific limitations on this.

[0089] More specifically, the anti-pinch force detection component 1221 and the stop head 1222 can be connected by a detachable fixed connection method such as snap-fit ​​or screw connection. The specific connection method can be set according to the actual design and usage requirements. This embodiment does not make specific limitations on this.

[0090] More specifically, the shape of the rod 1212 can be set as a cylinder, prism, or other shape, and correspondingly, the shape of the through hole provided on the slide 1211 can also be set as a cylinder, prism, or other shape. The specific shape can be set according to actual design and usage requirements, and this embodiment does not impose specific limitations on it.

[0091] More specifically, the shapes of the first connecting portion 1213 and the second connecting portion 1214 can be set as cuboids, prisms, or other shapes. The specific shape can be set according to actual design and usage requirements; this embodiment does not impose specific limitations on this.

[0092] More specifically, the stop 1222 is made of a flexible and elastic material, such as rubber or plastic. The specific material can be set according to actual design and usage requirements, and this embodiment does not make specific limitations in this regard.

[0093] More specifically, the anti-pinch force detection component 1221 is set as a shear force sensor, and the model of the shear force sensor can be set as BROSA shear force sensor, 9143B shear force sensor, etc., which can be set according to actual design and usage requirements. This embodiment does not make specific limitations on this.

[0094] It should be noted that the connection between the sliding rod and the anti-pinch force detection component 1221 via the second connecting part 1214 increases the connection surface between the sliding rod and the anti-pinch force detection component 1221, thereby strengthening the stability of the connection between the sliding rod and the anti-pinch force detection component 1221. The stop 1222 protects the anti-pinch force detection component 1221 from damage caused by the electric sliding door directly applying force to it. Compared to having only one rod part 1212, the connection between the first connecting part 1213 and the second connecting part 1214 via two rod parts 1212 increases the stability of the connection between the first connecting part 1213 and the second connecting part 1214. The connection between the sliding rod and the first cylinder 1216 via the first connecting part 1213 increases the connection surface between the sliding rod and the first cylinder 1216, strengthening the stability of the connection between the sliding rod and the first cylinder 1216. Furthermore, the first connecting part 1213 is connected to the output end of the first cylinder 1216 via a floating joint 1215. This not only increases the convenience of installing and connecting the first connecting part 1213 and the first cylinder 1216, but also eliminates errors that occur during installation and connection, thereby improving the accuracy of the opening and closing durability test bench for the electric sliding door. Compared to other driving components, using the first cylinder 1216 as the first driving component enhances its adaptability to the environment, thus avoiding the impact of environmental changes on the test results caused by variations in temperature and humidity, further improving the accuracy of the opening and closing durability test bench for the electric sliding door.

[0095] Another embodiment of this invention provides an opening and closing durability test bench for an electric sliding door of an automobile, such as... Figure 1 , Figure 2 and Figure 4 As shown, the stall component 220 also includes a stall base plate 223, which is slidably connected to the stall frame 210, allowing the stall base plate 223 to slide relative to the stall frame 210 in the height direction C and the width direction A of the stall frame 210. The second telescopic component 221 includes a mounting plate 2211 and a second drive member; one end of the mounting plate 2211 is rotatably connected to the stall base plate 223 about an axis in the height direction C of the stall frame 210, and a fastener is provided between the mounting plate 2211 and the stall base plate 223 to lock the position of the mounting plate 2211 relative to the stall base plate 223. The second drive member is fixedly connected to the side of the mounting plate 2211 away from the stall base plate 223, and the stall force detection component 222 is disposed on the output end of the second drive member.

[0096] Specifically, the stall device 20 can be configured by providing two sliding grooves on the stall frame 210 or the stall base plate 223, extending respectively along the height direction C and the width direction A of the stall frame 210; providing protrusions on the stall base plate 223 or the stall frame 210 that fit the sliding grooves; and providing a locking member between the sliding grooves and the protrusions, so that the stall base plate 223 can slide relative to the stall frame 210 in the height direction C and the width direction A of the stall frame 210. Alternatively, sliding grooves can be provided on the stall frame 210 and the stall base plate 223 respectively, and sliding fasteners can be provided between the sliding grooves, so that the stall base plate 223 can slide relative to the stall frame 210 in the height direction C and the width direction A of the stall frame 210. Preferably, in order to simplify the structure of the stall component 220, in this embodiment, grooves are provided on the stall frame 210 and the stall base plate 223 respectively, and sliding fasteners are provided between the grooves, so that the stall base plate 223 can slide relative to the stall frame 210 in the height direction C and the width direction A of the stall frame 210.

[0097] More specifically, the mounting plate 2211 can be rotatably connected to the stall base plate 223 via a hinge 224, a hinge, a gear or other connecting structure. The specific connection can be set according to actual design and usage requirements. This embodiment does not make any specific limitations on this.

[0098] More specifically, the fasteners between the mounting plate 2211 and the stall base plate 223 can be configured as support rods, buckles or other structures, which can be set according to actual design and usage requirements. This embodiment does not make specific limitations on this.

[0099] More specifically, the connection method between the second driving component and the mounting plate 2211 can be set as snap-fit, screw-fit, or other connection methods, which can be set according to actual design and usage requirements. This embodiment does not make specific limitations on this.

[0100] More specifically, the second driving component can be configured as an electric telescopic rod, a cylinder, or other components. Preferably, in order to reduce the impact of environmental changes on the second driving component, the second driving component in this embodiment is configured as a cylinder.

[0101] It should be noted that the second driving component can drive the stall detection component to be in an extended or retracted state relative to the electric sliding door under test along the length direction B of the stall frame 210, thereby completing the detection of stall force. Since the electric sliding door will rotate a certain angle around the height direction C of the stall frame 210 during opening and closing, one end of the mounting plate 2211 is rotatably connected to the stall base plate 223 around an axis on the height direction C of the stall frame 210. This allows the stall device 20 to adjust the angle of the stall component 220 according to the different angles around the height direction C of the stall frame 210 during the opening or closing of the electric sliding door, so as to detect the stall force of the electric sliding door at different positions. The stall base plate 223 is slidably connected to the stall frame 210, which allows the stall base plate 223 to drive the stall component 220 to slide relative to the stall frame 210 in the height direction C and the width direction A of the stall frame 210. This facilitates the stall device 20 in adjusting the position of the stall component 220, thereby enabling the stall device 20 to detect the stall force of electric sliding doors of different sizes and improving the convenience of using the opening and closing durability test bench for electric sliding doors.

[0102] Another embodiment of this invention provides an opening and closing durability test bench for an electric sliding door of an automobile, such as... Figure 1 , Figure 2 and Figure 4 As shown, the stall force detection assembly 222 includes a stall force detection element 2221 and a rubber head 2222. The second driving element is configured as a second cylinder 2212. Both ends of the stall force detection element 2221 are connected to the output end of the second cylinder 2212 and the rubber head 2222 respectively via adapters 2223. One end of the mounting plate 2211 is rotatably connected to the stall base plate 223 via a hinge 224. The fasteners include a snap-fit ​​head 225 disposed on one of the mounting plate 2211 and the stall base plate 223, a snap-fit ​​seat 226 disposed on the other, and a diagonal brace disposed on the hinge 224; and the snap-fit ​​head 225 and the snap-fit ​​seat 226 are adapted to each other.

[0103] Specifically, the latch head 225 can be disposed on the mounting plate 2211 or on the stall base plate 223. Correspondingly, the latch seat 226 can be disposed on the stall base plate 223 or on the mounting plate 2211. The specific design can be determined according to actual design and usage requirements, and this embodiment does not impose any specific limitations on it.

[0104] More specifically, the stall force detection component 2221 is configured as a force sensor, and its specific model can be configured as a 1050C force sensor, a 1022V force sensor, a 1061V1 force sensor, a 1210C1 force sensor, etc. The specific model can be set according to actual design and usage requirements, and this embodiment does not make specific limitations on it.

[0105] It should be noted that the rubber abutment 2222 allows the electric sliding door to apply force to the stall force detection component 2221 through the rubber abutment 2222, thus avoiding damage to the stall force detection component 2221 caused by the electric sliding door directly applying force to it. Compared to other drive components, the second drive component, configured as the second cylinder 2212, enhances its environmental adaptability, thereby avoiding the impact of environmental changes on the test results due to variations in temperature and humidity, and further improving the accuracy of the opening and closing durability test bench for the electric sliding door. The adapters 2223 at both ends of the stall force detection component 2221 increase the ease of installation between the two ends of the stall force detection component 2221 and the second cylinder 2212 and the rubber abutment 2222. Compared to other rotating connection methods, the hinge 224 connection simplifies the rotating connection structure between the mounting plate 2211 and the stall base plate 223. The diagonal brace on hinge 224 prevents the mounting plate 2211 from rotating relative to the stall base plate 223 after the angle of the stall component 220 is adjusted. The latch head 225 and latch seat 226 lock the position of the mounting plate 2211 relative to the stall base plate 223.

[0106] Another embodiment of this invention provides an opening and closing durability test bench for an electric sliding door of an automobile, such as... Figure 1 and Figure 2 As shown, the anti-pinch frame 110 includes a base 111 and a support 112, and the stall frame 210 includes a base 211 and a support 212. One end of the support 112 of the anti-pinch frame 110 is connected to one side of the base 111, and the other end extends in a direction perpendicular to the base 111; and the anti-pinch base plate 123 is slidably connected to the side wall of the support 112 of the anti-pinch frame 110. One end of the support 212 of the stall frame 210 is connected to one side of the base 211, and the other end extends in a direction perpendicular to the base 211; and the stall base plate 223 is slidably connected to the side wall of the support 212 of the stall frame 210.

[0107] Specifically, the support base 112 and the base 111 of the anti-pinch frame 110 can be fixedly connected by welding, snap-fitting, screwing, or other methods, or they can be integrally formed. The support base 212 and the base 211 of the stall frame 210 can be fixedly connected by welding, snap-fitting, screwing, or other methods, or they can be integrally formed. The specific connection can be set according to actual design and usage requirements, and this embodiment does not impose specific limitations on this.

[0108] It should be noted that the anti-pinch frame 110, including the base 111 and the support 112, can make the anti-pinch frame 110 smaller in size, and the stall frame 210, including the base 211 and the support 212, can make the stall frame 210 smaller in size, thereby reducing the space occupied by the anti-pinch frame 110 and the stall frame 210.

[0109] Another embodiment of this invention provides an opening and closing durability test bench for an electric sliding door of an automobile, such as... Figure 1 and Figure 2 As shown, a first support moving assembly 113 is provided on the base 111 of the anti-pinch frame 110 on the side away from the support seat 112; a second support moving assembly 213 is provided on the base 211 of the stall frame 210 on the side away from the support seat 212. The first support moving assembly 113 includes a caster wheel component and a lifting support leg 1133. The caster wheel component includes a caster wheel 1131 and a connector 1132. The second support moving assembly 213 includes a caster wheel component and a lifting support leg 2133. The caster wheel component includes a caster wheel 2131 and a connector 2132.

[0110] In the first support and movement assembly 113, one end of the connector 1132 is connected to one side of the base 111 of the anti-pinch frame 110, and the other end is rotatably connected to the caster wheel 1131. One end of the lifting support leg 1133 is connected to one side of the base 111 of the anti-pinch frame 110. The lifting support leg 1133 can switch between raised and lowered states. When the lifting support leg 1133 is in the raised state, its height is higher than the height of the caster wheel assembly; when the lifting support leg 1133 is in the lowered state, its height is lower than the height of the caster wheel assembly.

[0111] In the second support and movement assembly 213, one end of the connector 2132 is connected to one side of the base 211 of the stall frame 210, and the other end is rotatably connected to the caster wheel 2131.

When the lifting support leg 2133 is in the raised state, its height is higher than the height of the caster wheel assembly; when the lifting support leg 2133 is in the lowered state, its height is lower than the height of the caster wheel assembly.

[0112] Specifically, in the first support and movement assembly 113, one end of the connector 1132 is fixedly connected to one side of the base 111 of the anti-pinch frame 110 by welding, snap-fitting, screwing, or other methods. The other end of the connector 1132 is rotatably connected to the caster wheel 1131 by a ball joint, pivot, or other structure. One end of the lifting support leg 1133 is fixedly connected to the base 111 of the anti-pinch frame 110 by welding, snap-fitting, screwing, or other methods. The number of caster wheels and lifting support legs 1133 can be set to one, two, three, four, etc. The specific number can be set according to actual design and usage requirements; this embodiment does not impose specific limitations on this.

[0113] More specifically, in the first support moving assembly 113, the lifting support leg 1133 may include an inner rod and an outer rod, and a locking member is provided between the inner rod and the outer rod to lock the inner rod when it is extended or retracted relative to the outer rod, thereby realizing the raising and lowering of the lifting support leg 1133. Alternatively, a telescopic structure may be provided between one side of the base 111 of the anti-pinch frame 110 and the lifting support leg 1133. By controlling the extension and retraction of the telescopic structure, the raising and lowering of the lifting support leg 1133 can be achieved. The specific design can be set according to actual design and usage requirements; this embodiment does not impose specific limitations on this. Furthermore, a support base is provided at the end of the lifting support leg 1133 away from the base 111 of the anti-pinch frame 110.

[0114] More specifically, in the second support and movement assembly 213, one end of the connector 2132 is fixedly connected to one side of the base 211 of the stall frame 210 by welding, snap-fitting, screwing, or other methods. The other end of the connector 2132 is rotatably connected to the caster wheel 2131 by a ball joint, pivot, or other structure.

The number of caster wheels and lifting support legs 2133 can be set to one, two, three, four, etc. The specific number can be set according to actual design and usage requirements; this embodiment does not impose specific limitations on this.

[0115] More specifically, in the second support moving assembly 213, the lifting support leg 2133 may include an inner rod and an outer rod, and a locking member is provided between the inner rod and the outer rod to lock the inner rod when it is extended or retracted relative to the outer rod, thereby realizing the raising and lowering of the lifting support leg 2133. Alternatively, a telescopic structure may be provided between one side of the base 211 of the stall frame 210 and the lifting support leg 2133. By controlling the extension and retraction of the telescopic structure, the raising and lowering of the lifting support leg 2133 can be achieved. The specific design can be set according to actual design and usage requirements; this embodiment does not impose specific limitations on this. Furthermore, a support base is provided at the end of the lifting support leg 2133 away from the base 211 of the stall frame 210.

[0116] It should be noted that the arrangement of the first support moving component 113 and the second support moving component 213 facilitates the movement of the anti-pinch frame 110 and the stall frame 210, thereby increasing the convenience of using the opening and closing durability test bench for the electric sliding door of the vehicle. Furthermore, when it is necessary to move the anti-pinch frame 110, the lifting support leg 1133 can be lowered, at which point the height of the lifting support leg 1133 is lower than the height of the caster wheel component, allowing the anti-pinch frame 110 to be moved via the caster wheel component. When it is not necessary to move the anti-pinch frame 110, the lifting support leg 1133 can be raised, at which point the height of the lifting support leg 1133 is higher than the height of the caster wheel component, preventing the anti-pinch frame 110 from moving if the caster wheel component is accidentally touched.

[0117] When the stall frame 210 needs to be moved, the lifting support leg 2133 can be lowered. In this state, the height of the lifting support leg 2133 is lower than the height of the caster wheel assembly, allowing the stall frame 210 to be moved via the caster wheel assembly. When the stall frame 210 does not need to be moved, the lifting support leg 2133 can be raised. In this state, the height of the lifting support leg 2133 is higher than the height of the caster wheel assembly, preventing the stall frame 210 from moving if the caster wheel assembly is accidentally touched.

[0118] Another embodiment of this invention provides an opening and closing durability test bench for an electric sliding door of an automobile, such as... Figures 1-4 As shown, the side wall of the support base 112 of the anti-pinch frame 110 is provided with a first sliding groove 1121 extending along the height direction of the support base 112, and the side wall of the support base 212 of the stall frame 210 is also provided with a first sliding groove 2121 extending along the height direction of the support base 212. The anti-pinch base plate 123 is provided with a second sliding groove 1231 extending along the width direction of the support base 112, and the stall base plate 223 is provided with a second sliding groove 2231 extending along the width direction of the support base 212. Sliding fasteners are provided between the support base 112 and the anti-pinch base plate 123 of the anti-pinch frame 110, and between the support base 212 and the stall base plate 223 of the stall frame 210.

[0119] The sliding fastener of the anti-pinch device 10 passes through the first slide groove 1121 and the second slide groove 1231, and cooperates with the first slide groove 1121 and the second slide groove 1231, so that the anti-pinch base plate 123 can slide relative to the support seat 112 of the anti-pinch frame 110 in the height direction and the width direction of the support seat 112. The sliding fastener of the stall device 20 passes through the first slide groove 2121 and the second slide groove 2231, and cooperates with the first slide groove 2121 and the second slide groove 2231, so that the stall base plate 223 can slide relative to the support seat 212 of the stall frame 210 in the height direction and the width direction of the support seat 212.

[0120] Specifically, the sliding fasteners between the support base 112 and the anti-pinch base plate 123 of the anti-pinch frame 110, and between the support base 212 and the stall base plate 223 of the stall frame 210, can all be configured as bolt and nut structures, screw and nut structures, etc. Their specific configurations can be determined according to actual design and usage requirements; this embodiment does not impose specific limitations on this. Furthermore, the radial dimensions of the bolt and screw heads and the radial dimensions of the nuts are greater than the width dimensions of the first sliding groove 1121 on the anti-pinch frame 110 and the second sliding groove 1231 on the anti-pinch base plate 123, and the radial dimensions of the bolt and screw heads and the radial dimensions of the nuts are greater than the width dimensions of the first sliding groove 2121 on the stall frame 210 and the second sliding groove 2231 on the stall base plate 223.

[0121] More specifically, the height direction of the support base 112 of the anti-pinch frame 110 is consistent with the height direction C of the anti-pinch frame 110. The height direction of the support base 212 of the stall frame 210 is consistent with the height direction C of the stall frame 210.

The width direction of the support base 212 of the stall frame 210 is consistent with the width direction A of the stall frame 210.

[0122] It should be noted that the sliding fastener configuration allows for sliding between the anti-pinch base plate 123 and the support seat 112 of the anti-pinch frame 110, and between the stall base plate 223 and the support seat 212 of the stall frame 210. It also allows for locking and unlocking between these two configurations. Furthermore, compared to other structures, this configuration simplifies the structure between the anti-pinch base plate 123 and the support seat 112 of the anti-pinch frame 110, and between the stall base plate 223 and the support seat 212 of the stall frame 210.

[0123] Another embodiment of this invention provides an opening and closing durability test bench for an electric sliding door of an automobile, such as...
