[0002] The car lampshade is an important component of the front and rear lamps of the car. Its main functions include protecting the lamps from damage caused by external environmental factors (such as impact, wind and sand, etc.), beautifying the appearance of the car body and increasing the overall visual effect of the car. In order to ensure that the car lampshade can work normally, it is necessary to conduct strength testing on the car lampshade after processing to ensure that the car lampshade can withstand the impact load during normal use and accidents, and protect the lamps from damage.

[0003] Existing strength detection technology usually only applies impact loads to car lampshades, but in actual situations, the environment in which car lampshades are subjected to external impacts is uncertain, and the environment in which car lampshades are located will also have a slight impact on them.

DETAILED DESCRIPTION

[0018] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0019] like Figure 1 As shown, an embodiment of the present invention is proposed, which provides an automobile lampshade strength detection device with an environmental simulation function, which is used for performing strength detection on a lampshade 101, and includes: a body 1; a heating element 2, which is arranged in the body 1 and is used for heating the environment in which the lampshade 101 is located; a transfer mechanism, which is arranged in the body 1 and is used for transferring the lampshade 101 to an impact detection area; a fixing mechanism, which is arranged in the body 1 and is used for performing multi-point comprehensive fixing of the lampshade 101, so that the lampshade 101 simulates a real fixing situation, thereby facilitating the smooth implementation of subsequent impact detection; an impact mechanism, which is arranged in the body 1 and is used for performing angle-variable impact detection on the lampshade 101, and through the cooperation of the impact mechanism and the transfer mechanism, impact detection is performed on different areas of the lampshade 101.

[0020] In the above scheme, it is intended to solve the problem that the existing technology cannot simulate the actual environment of the lampshade 101 during normal use when performing strength detection on the lampshade 101, so as to improve the effectiveness of the results obtained when the lampshade 101 is tested for strength. This embodiment is a car lampshade strength detection device with an environmental simulation function. When using the device to perform strength detection on the lampshade 101, a plurality of heating elements 2 are used to heat the space in the detection area to simulate the high temperature environment of the lampshade 101 during use, so as to make the detection result more reliable. At the same time, the degree of heating can also be changed to simulate the real environment at different temperatures, so as to increase the diversity of the detection of the lampshade 101, increase the data for the strength detection of the lampshade 101, and thus improve the effect of the strength detection of the lampshade 101.

[0021] like Figure 2 As shown, the transfer mechanism includes: a first transfer module 301, installed in the body 1; a mounting plate 302, arranged on the first transfer module 301; a second transfer module 303, installed on the mounting plate 302, and the first transfer module 301 and the second transfer module 303 cooperate with the impact mechanism to perform a comprehensive impact detection on the area in the XY axis direction of the lampshade 101.

[0022] In the above scheme, the first transfer module 301 and the second transfer module 303 are both composed of an electric slider and a slide rail, which are used to transfer the lampshade 101 to be inspected to the inspection area. The power sources of the first transfer module 301 and the second transfer module 303 are both servo motors, which are used to make the movement of the lampshade 101 more precise.

[0023] like Figure 1-Figure 6As shown, the fixing mechanism includes: a T-shaped rod 401, fixedly connected to the body 1; two vertical rods 402, which are arranged in a mirror image and are both slidably connected to the T-shaped rod 401; a vertical plate 403, which is arranged on the vertical rod 402; a fixed shell 404, fixedly connected to the second transfer module 303, and the vertical plate 403 is provided with uniformly arranged cavities 405, and the cavities 405 are filled with a transmission medium; first tubes 406, the number of which is the same as the number of cavities 405, are connected to adjacent cavities 405, and the first tubes 406 are fixedly connected to the adjacent vertical plates 403; a first sliding member 407, which is slidably connected to the cavity 405; a telescopic member 408, which is fixedly connected to the first sliding member 407, and the telescopic member 408 is filled with a transmission medium, and the telescopic member 408 is connected to the adjacent first tube 406; a second tube 409 are two mirror-image arrangements, both of which are fixed to the fixed shell 404, and the second tube 409 is connected to the adjacent first tube 406; a storage box 410 is fixed to the fixed shell 404, and is used to store the transmission medium; a third tube 411 is fixed to the fixed shell 404, and the third tube 411 is connected to the storage box 410, and the fixed shell 404 is provided with a first cavity 412 and a second cavity 413, and the second tube 409 and the third tube 411 are both connected to the first cavity 412, and the first cavity 412 is filled with the transmission medium, and the second cavity 413 is filled with the compression medium and the support medium; a support component is provided in the fixed shell 404, and is used to support the lampshade 101, and an adsorption component is provided in the fixed shell 404, and is used to adsorb and fix the lampshade 101.

[0024] In the above scheme, the number of vertical plates 403 is the same as the number of vertical poles 402, the transmission medium in the cavity 405 is hydraulic oil, the transmission medium in the telescopic member 408 is hydraulic oil, the connection between the third tube 411 and the storage box 410 is located at the lower part of the storage box 410, which is used to ensure that the hydraulic oil in the storage box 410 always submerges the connection, the compression medium in the second cavity 413 is nitrogen, and the support medium in the second cavity 413 is a non-Newtonian fluid, which is used to fully support the lampshade 101. In the process of the adsorption component carrying the lampshade 101 to move backward, after the lampshade 101 moves to contact with the telescopic member 408, the lampshade 101 begins to squeeze the telescopic member 408, and the telescopic member 408 is compressed. At the same time, under the squeezing effect of the protrusion of the lampshade 101, the telescopic member 408 also moves upward, and the telescopic member 408 drives the first sliding member 407 to move upward together. During the process, the hydraulic oil in the cavity 405 and the telescopic member 408 enters the second tube 409 through the first tube 406, and the hydraulic oil in the second tube 409 enters the storage box 410 after passing through the first cavity 412 and the third tube 411. The hydraulic oil accumulates in the storage box 410 until the lampshade 101 moves to the detection area. At this time, several telescopic members 408 fully fix the lampshade 101, thereby simulating the actual multi-point fixation of the lampshade 101, making the detection process more realistic, thereby improving the effect of strength detection of the lampshade 101.

[0025] like Figure 3 and Figure 4 As shown, the support assembly includes: a fourth tube 501 fixed to the fixed shell 404, the fourth tube 501 is connected to the second cavity 413; a support member 502 is arranged between the two vertical plates 403 through a horizontal plate, and the support member 502 is connected to the fourth tube 501.

[0026] In the above scheme, there are two fourth tubes 501 arranged in mirror image, which are used to make the support member 502 expand evenly. The shape of the support member 502 is the same as the edge shape of the lampshade 101, and is used to fully support the lampshade 101. The non-Newtonian fluid in the second cavity 413 enters the support member 502 through the fourth tube 501, so that the support member 502 expands and fully supports the lampshade 101. At the same time, when the lampshade 101 is subjected to impact detection, the load can be evenly distributed to the bottom surface of the lampshade 101 (the non-Newtonian fluid hardens when subjected to severe impact to fully support the lampshade 101), thereby simulating the actual state of the lampshade 101 installed on the vehicle, thereby improving the accuracy of the strength test results of the lampshade 101.

[0027] like Figure 4 and Figure 6 As shown, the adsorption component includes: a fan 601, which is installed on the fixed shell 404, and the fan 601 is connected to the fixed shell 404; a suction cup 602, which is arranged on the fixed shell 404; a second sliding member 603, which is slidably connected in the fixed shell 404; a blocking member 604, which is arranged in the fixed shell 404, and the blocking member 604 and the fixed shell 404 are sealed together, a first elastic element 605 is fixedly connected between the blocking member 604 and the fixed shell 404, a second elastic element 606 is fixedly connected between the second sliding member 603 and the fixed shell 404, and a through hole 607 is provided on one side of the fixed shell 404 close to the suction cup 602; a blocking structure, which is arranged on the second sliding member 603, is used to block the third tube 411.

[0028] In the above scheme, the suction cup 602 is made of soft rubber material and is used to fully contact the lampshade 101. The sealing piece 604 is truncated cone-shaped, and its outer diameter gradually increases from top to bottom, and is used to contact and seal the fixed shell 404. The first elastic element 605 is a tension spring, which is used to reset the sealing piece 604. The second elastic element 606 is a spring, which is used to reset the second sliding piece 603. There are four through holes 607 in a circular array, which are used to increase the gas flow rate. When the lampshade 101 needs to be adsorbed, the fan 601 is started, the fan 601 starts to exhaust air, and the sealing piece 604 starts to move downward under the action of negative pressure. The first elastic element 605 is deformed, and the sealing piece 604 is out of contact with the fixed shell 404. The air between the suction cup 602 and the lampshade 101 is reduced and negative pressure is generated, so that the lampshade 101 is adsorbed and fixed, and then the adsorbed lampshade 101 is transferred to the detection area by the first transfer module 301 until the lampshade 101 moves to the detection area.

[0029] like Figure 4 and Figure 5 As shown, the blocking structure includes: an extrusion rod 701, which is slidably connected to the second sliding member 603, a blocking block 704 and a third tube 411 for blocking cooperation, a third elastic element 702 is fixedly connected between the second sliding member 603 and the extrusion rod 701; a guide block 703, which is fixedly connected to the fixed shell 404; a blocking block 704, which is fixedly connected to the extrusion rod 701, and a blocking block 704 and a guide block 703 are slidably connected.

[0030] In the above scheme, the third elastic element 702 is a spring, which is used to reset the extrusion rod 701. During the impact detection of the lampshade 101, the fan 601 blows air into the fixed shell 404, and the blocking member 604 begins to move upward (reset) under the action of wind force and the pulling force of the first elastic element 605, and contacts and seals with the fixed shell 404 again. At this time, the suction cup 602 is separated from the lampshade 101. During the process, the second sliding member 603 moves downward under the action of wind force, and the second elastic element 606 and the third elastic element 702 are compressed. The elastic force of the third elastic element 702 is applied to the extrusion rod 701, and the extrusion rod 701 drives the blocking block 704 to move downward together, and the blocking block 704 gradually blocks the third tube 411. At this time, the first sliding member 407 and the telescopic member 408 are both in a locked state (the hydraulic oil cannot flow, and the two cannot move), thereby providing a stable fixed support for the lampshade 101, thereby preventing the lampshade 101 from being displaced when impacted during the strength detection process, affecting the normal application of the impact force, and ultimately reducing the effect of the strength detection of the lampshade 101.

[0031] like Figure 3 , Figure 7 and Figure 8As shown, the impact mechanism includes: a mounting shell 801, fixedly connected to the body 1; a moving part 802, slidably connected to the mounting shell 801; an impact rod 803, slidably connected to the moving part 802; a rack 804, fixedly connected to the moving part 802; a motor 805, installed on a T-shaped rod; a missing gear 806, fixedly connected to the output shaft of the motor 805, the missing gear 806 and the rack 804 transmission cooperation; a locking assembly, arranged in the mounting shell 801, for changing the relative connection relationship between the moving part 802 and the impact rod 803.

[0032] In the above scheme, during the process of the lampshade 101 rotating toward the detection area, when the lampshade 101 contacts the impact rod 803, the impact rod 803 begins to move upward under the action of the convex squeezing of the lampshade 101, so that the impact force applied to the lampshade 101 by the impact rod 803 during the subsequent strength detection of the lampshade 101 is the same, so that the strength of each part of the lampshade 101 is detected to the same extent, thereby improving the uniformity of the strength detection, and the output shaft of the motor 805 drives the missing gear 806 to rotate. After the missing gear 806 rotates to engage with the rack 804, the rack 804 begins to drive the moving part 802 to move upward, and the moving part 802 drives the impact rod 803 to move upward together. When the missing gear 806 rotates to disengage from the rack 804, the rack 804 and the parts thereon begin to move downward under the action of their own gravity and impact the lampshade 101, thereby completing the strength detection.

[0033] like Figure 7 and Figure 8 As shown, the locking assembly includes: an intermediate shell 901, which is fixedly connected to the mounting shell 801, the intermediate shell 901 is connected to the moving part 802, and the intermediate shell 901 and the moving part 802 are both filled with a transmission medium; a third sliding part 902, which is slidably connected to the intermediate shell 901, a limiting part 904 is squeezed and matched with the third sliding part 902, and a fourth elastic element 903 is fixedly connected between the third sliding part 902 and the intermediate shell 901; a limiting part 904, which is slidably connected to the intermediate shell 901, and a fifth elastic element 905 is fixedly connected between the intermediate shell 901 and the limiting part 904; a limiting rod 906, which is fixedly connected to the missing gear 806, and the limiting rod 906 is limitedly matched with the limiting part 904.

[0034] In the above scheme, the transmission medium in the middle shell 901 and the moving part 802 is hydraulic oil, the fourth elastic element 903 is a spring, which is used to reset the third sliding part 902, and the side surfaces of the limiting member 904 and the third sliding member 902 that are squeezed and matched with each other are rough surfaces, which are used to increase the friction between the two. The left part of the limiting member 904 is set to a quarter of a circular ring, and the upper and lower sides of this part are chamfered to allow the limiting rod 906 to pass through. The fifth elastic element 905 is a spring, which is used to reset the limiting member 904. During the rotation of the missing gear 806, the missing gear 806 drives the limiting rod 906 to rotate together. Before the missing gear 806 rotates to mesh with the rack 804, the limiting rod 906 first contacts with the limiting member 904 and squeezes it, and the limiting member 904 moves to the right (such as Figure 8 direction as an example), the fifth elastic element 905 is compressed, and at the same time, the limiting member 904 is in close contact with the third sliding member 902, so as to limit the third sliding member 902, that is, to ensure the stability between the moving member 802 and the impact rod 803 when the lampshade 101 is subsequently impacted, and to avoid relative movement between the two during the detection process, resulting in a reduction in the impact force applied to the lampshade 101, thereby reducing the detection effect.

[0035] like Figure 7-Figure 9 As shown, it also includes: an adjustment mechanism, which is arranged on one of the vertical plates 403 and is used to adjust the angle of the lampshade 101; the adjustment mechanism includes: a connecting rod 1001, which is fixedly connected to the adjacent vertical plate 403, and the vertical rod 402 is rotatably connected to the vertical plate 403, and the rotation center of the two coincides with the axis of the connecting rod 1001; a rotating member 1002, which is splined to the connecting rod 1001, and the rotating member 1002 is fixed to the mounting shell 801 through an L-shaped rod; a toggle member 1003, which is rotatably connected to the mounting shell 801, and the toggle member 1003 is connected to the output shaft of the motor 805. The two components are connected by a pulley and belt transmission, the rotating member 1002 and the toggle member 1003 are limited and matched, and when the toggle member 1003 rotates one circle, the rotating member 1002 rotates 1 / N circle, which is used to deflect the lampshade 101, and the transmission ratio between the output shaft of the motor 805 and the toggle member 1003 is 1:1, and the meshing time of the rack 804 and the missing gear 806 is inconsistent with the matching time of the rotating member 1002 and the toggle member 1003, which is used to make the relative sliding movement between the moving member 802 and the mounting shell 801 and the deflection movement of the connecting rod 1001 proceed in sequence.

[0036] In the above scheme, the toggle member 1003 rotates one circle, and the rotating member 1002 rotates 1 / N circle. The ratio here can be accurately defined according to actual conditions, so as to detect the strength of the lampshade 101 when the position is self-adjusted, thereby reducing the operating steps of the staff and improving the efficiency of the detection work. During the rotation of the output shaft of the motor 805, the output shaft of the motor 805 transmits power to the toggle member 1003 through the pulley belt, and then the toggle member 1003 starts to rotate. When the toggle member 1003 rotates to the toggle rotating member 1002, the missing gear 806 is in an idling state (not engaged with the rack 804). Then, under the action of the toggle member 1003, the rotating member 1002 starts to rotate, and the rotating member 1002 drives the connecting rod 1001 to rotate together.
