[0002] With the rapid development of the automotive industry and the continuous advancement of tire material technology, the demand for tire durability and environmental adaptability testing is increasing. During long-term use, tires are subjected to various factors such as sunlight, high temperatures, and mechanical stress, leading to a gradual decline in material performance and aging phenomena such as cracking, hardening, or deformation. To assess tire lifespan and reliability in a shorter timeframe, accelerated aging test chambers are widely used in product development and quality control.

[0003] Accelerated tire aging test chambers are devices that simulate the light and temperature conditions of real-world use environments. By intensifying test parameters, they accelerate the aging process of materials, thereby allowing for the observation and analysis of tire performance changes under different operating conditions. These devices typically integrate heat sources, light sources, temperature control systems, and sample support and transmission structures. They can continuously irradiate and heat tires in a closed environment, and some models also feature rotation capabilities to achieve more uniform aging effects. With increasing testing requirements, modern test chambers have gradually incorporated designs such as adjustable irradiation distances and dynamic monitoring to adapt to the testing needs of different tire specifications, improving the comprehensiveness and operability of the tests, and playing a vital role in tire manufacturing and materials research.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figure 1-4 The present invention provides the following technical solution: A tire aging accelerated testing chamber includes: Aging chamber 1; Door panel 2 is rotatably connected to the side of aging chamber 1 via a pivot. Temperature control box 4 is connected to the upper end of aging box 1. A lamp cover 6 is fixedly connected to the inner wall of temperature control box 4, and an aging lamp 7 is connected inside the lamp cover 6. Connecting rod 21 is rotatably connected to the side end of aging chamber 1; Tire 22, tire 22 is connected to the circumferential surface of connecting rod 21; The adjustment mechanism includes a truss 8, a slide rail 9, a first cylinder 10, and an upper frame 11. The truss 8 is fixedly connected to the upper end of the aging chamber 1, the slide rail 9 is slidably connected to the side end of the truss 8, the first cylinder 10 is fixedly connected to the upper end of the truss 8, the upper frame 11 is connected to the output end of the first cylinder 10, and the upper frame 11 is connected to the temperature control box 4.

[0017] In a specific embodiment of this utility model, when it is necessary to test the aging performance of a tire, the door panel 2 is opened, the tire 22 to be tested is placed on the connecting rod 21, and then the door panel 2 is closed. The aging lamp 7 in the temperature control chamber 4 is then turned on, and the lamp cover 6 directs the light source in a concentrated manner so that the light shines evenly onto the surface of the tire 22. In this way, the tire 22 simulates the aging process during long-term use under the combined action of light and the thermal environment provided by the temperature control chamber 4. When it is necessary to adjust the light intensity or irradiation distance, the first cylinder 10 pushes the upper frame 11 to move along the slide rail 9, causing the temperature control chamber 4 to rise and fall as a whole, thereby changing the relative position between the aging lamp 7 and the tire 22. In this way, the irradiation conditions can be adjusted according to different test requirements to adapt to the test requirements of various tire specifications. When it is necessary to observe the deformation of the tire 22 during the test, the connecting rod 21 can drive the tire 22 to rotate slowly, so that each part of the tire 22 is exposed to the light area in turn. In this way, the aging process is more uniform, improving the comprehensiveness and operability of the test.

[0018] Please refer to the details. Figure 1-4 The slide rail 9 is fixedly connected to the side end of the slide frame 13. The slide rail 9 is connected to the temperature control box 4. The truss 8 is fixedly connected to the side end of the rear frame 12.

[0019] In this embodiment: when the first cylinder 10 pushes the upper frame 11 to move, it drives the temperature control box 4 to move along the slide rail 9. The sliding frame 13 is fixed to the side of the slide rail 9 to enhance the guidance of the sliding process and make the temperature control box 4 rise and fall more smoothly. In this way, the distance adjustment between the aging lamp 7 and the tire 22 is more stable. The rear frame 12 is connected to the side of the truss 8 to strengthen the connection strength of the overall structure. In this way, when the temperature control box 4 is rising or falling or working for a long time, the whole device maintains good support, ensuring the continuity of the test process and the reliability of operation.

[0020] Please refer to the details. Figure 1-4 The temperature control box 4 has a heat dissipation hole 5 at the top and a window 3 at the side of the door panel 2.

[0021] In this embodiment: when the internal temperature of the temperature control chamber 4 rises, the heat is naturally discharged through the heat dissipation hole 5 at its upper end, promoting the exchange of air inside and outside the chamber and helping to regulate the thermal environment inside the temperature control chamber 4; in this way, the heat generated when the aging lamp 7 is working can be effectively released, avoiding local overheating; when it is necessary to observe the internal condition of the aging chamber 1 during the test, the surface changes of the tire 22 can be directly viewed through the window 3 set on the side of the door panel 2; in this way, the test status can be monitored in real time without opening the door panel 2, which is convenient for recording the deformation or crack development during the aging process.

[0022] Please refer to the details. Figure 1-4 A second sprocket 25 is fixedly connected to the side end of the connecting rod 21, a motor 23 is fixedly connected to the side end of the aging chamber 1, a first sprocket 24 is fixedly connected to the output end of the motor 23, and a chain 26 is rotatably connected to the circumferential surface of the first sprocket 24 and the second sprocket 25.

[0023] In this embodiment: when it is necessary for the tire 22 to rotate during the test, the motor 23 is started, and its output end drives the first sprocket 24 to rotate. Through the chain 26, the power is transmitted to the second sprocket 25 fixed on the connecting rod 21, thereby driving the connecting rod 21 to rotate. In this way, the tire 22 rotates slowly together with the connecting rod 21, so that its various parts are exposed to the irradiation area of ​​the aging lamp 7 in sequence. When the test continues, the periodic rotation helps to distribute the light and heat effects on the tire surface more evenly. In this way, the multi-directional aging of the tire in actual use can be effectively simulated, improving the comprehensiveness and repeatability of the test.

[0024] Please refer to the details. Figure 1-4 A side frame 14 is fixedly connected to the inner wall of the side end of the aging chamber 1. A test plate 16 and a locking block 17 are connected to the side end of the side frame 14. The test plate 16 is connected to the tire 22. A locking groove 15 is opened on the side end of the side frame 14. The side end of the locking block 17 is engaged with the locking groove 15.

[0025] In this embodiment: when the tire 22 deforms during the aging test, the test plate 16 moves with the outer surface of the tire, and its connecting end is displaced on the side frame 14. By monitoring the positional change of the test plate 16, the deformation of the tire material can be reflected; thus, visual reference information is provided for assessing the degree of aging; the locking block 17 engages with the locking groove 15 on the side end of the side frame 14 to realize the quick installation and positioning of the test plate 16; thus, it is convenient to replace the test plate 16 with a suitable one according to different tire specifications, improving the applicability and flexibility of the device.

[0026] Please refer to the details. Figure 1-4 The aging chamber 1 is fixedly connected to a box body 18 on its side, and a second cylinder 19 is fixedly connected to the side of the box body 18. A detection device 20 is provided on the side of the locking block 17, and the detection device 20 is connected to the output end of the second cylinder 19.

[0027] In this embodiment: when it is necessary to dynamically monitor the physical changes on the surface of the tire 22, the second cylinder 19 pushes the detection device 20 to move along the side of the housing 18, so that the detection device 20 approaches or contacts the test plate 16; in this way, the detection device 20 can acquire the deformation information of the tire 22 in real time during the aging process; when the test plate 16 is displaced due to tire deformation, the locking block 17 remains positioned in the locking groove 15 to ensure that the relative positional relationship between the detection device 20 and the test plate 16 is stable; this facilitates continuous tracking of the aging response of the tire material; after the detection device 20 completes data acquisition, the second cylinder 19 drives it to retract to the initial position to avoid the long-term impact of the high temperature environment on the detection element; in this way, non-destructive and repeatable monitoring of the tire aging process is achieved, improving the ability to acquire test data.

[0028] The working principle and usage process of this utility model are as follows: When using the device, first open the door panel 2 and place the tire to be tested 22 onto the connecting rod 21, ensuring proper installation; close the door panel 2 to seal the internal space of the aging chamber 1; start the motor 23, whose output end drives the first sprocket 24 to rotate, which is transmitted to the second sprocket 25 through the chain 26, thereby driving the connecting rod 21 to rotate slowly, so that the tire 22 rotates at a uniform speed inside the aging chamber 1; turn on the aging lamp 7 in the temperature control chamber 4, and the light is concentrated by the lamp cover 6 and irradiates the surface of the tire 22. At the same time, the temperature control chamber 4 generates heat, which works in conjunction with the light to simulate the natural aging environment; according to the test standard requirements, start the first cylinder 10, whose output end pushes the upper frame 11 to move along the slide rail 9, driving the temperature control chamber 4 to rise and fall as a whole, adjusting the irradiation distance between the aging lamp 7 and the tire 22. The deformation of the tire 22 surface is observed through the probe window 3 on the door panel 2. When deformation data is needed, the second cylinder 19 is activated, and its output end pushes the detection device 20 to extend, so that the detection device 20 is close to the test plate 16 driven by the tire 22 to achieve dynamic monitoring. After the test is completed, the second cylinder 19 drives the detection device 20 to retract into the box 18. During the test, the heat dissipation hole 5 at the top of the temperature control box 4 continuously discharges internal heat to maintain thermal environment circulation. The slot 15 on the side frame 14 cooperates with the block 17 to ensure that the test plate 16 is reliably positioned. The rear frame 12 and the sliding frame 13 respectively enhance the structural stability of the truss 8 and the slide rail 9 to ensure the smooth operation of the equipment. After the aging test of the set time is completed, the power is turned off, and after the temperature drops, the door panel 2 is opened, the tire 22 is removed, and subsequent performance evaluation is carried out.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through the control unit. The control circuit of the control unit can be implemented by simple programming by those skilled in the art, which is common knowledge in the field.
