Description

TECHNICAL FIELD

[0001] The utility model relates to clothing test device technical field, more specifically, it relates to a wide temperature range clothing thermal performance test device. BACKGROUND

[0002] Wide temperature range clothing refers to the clothing that can keep the comfort of the wearer in a wide temperature range, and such clothing is usually designed to cope with changing weather conditions, such as changes from cold winter to warm spring or autumn. The thermal performance test of such clothing is an essential part, and therefore involves a test device specially used for clothing thermal performance test.

[0003] The conventional test device usually uses a thermal manikin as the carrier of the clothing, and records the temperature change of the thermal manikin by using a detection system installed after heating the thermal manikin by using a heating system, so as to obtain the determination of the thermal performance of the clothing. However, the conventional thermal manikin for clothing thermal test is usually set statically, but in the real situation, the human body is always moving. Once the human body moves, the clothing will collide and rub with the human body, which will affect the air flow between the clothing and the human body. In this case, the structural design of the clothing will also have a certain influence on its thermal performance. The thermal performance test of the clothing also needs to consider the structural design of the clothing. In order to more accurately test the thermal performance of the clothing, a new scheme needs to be proposed to solve the problem that the influence of the structural design of the clothing on the thermal performance is ignored in the process of the thermal performance test of the clothing. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a wide temperature range clothing thermal performance test device, which can simulate human body movement to improve the accurate test of the thermal performance of the clothing.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a wide temperature range clothing thermal performance test device, comprising: a device support, a control device arranged on the device support for controlling the operation of the test device, a thermal manikin fixedly connected with the device support, the thermal manikin comprising: a manikin body, four limbs connected with the manikin body through a movable mechanism;

[0006] The movable mechanism comprises: a driving motor fixedly connected in the manikin body, and a deep groove ball bearing for connecting the limbs and the manikin body, wherein the output end of the driving motor is provided with an output gear;

[0007] The deep groove ball bearing comprises: an inner bearing, a ball and an outer bearing; wherein the inner bearing and the outer bearing are rotatably arranged through the ball, and the inner ring surface of the inner bearing is arrayed with a plurality of inner gears for meshing with the output gear of the driving motor.

[0008] The present invention is further configured such that: a connecting component is fixedly connected to one end of the inner bearing facing the limb, and the limb is connected to the inner bearing through the connecting component.

[0009] The present invention is further configured such that: the limb includes: a hind limb connected to an inner bearing via the first connecting component, and a forelimb connected to the hind limb via the second connecting component;

[0010] The second connecting component includes: a spherical connecting block fixedly connected to the connecting surface of the hind limb facing the forelimb, and a spherical groove formed on the connecting surface of the forelimb facing the hind limb, wherein the spherical connecting block matches the spherical groove and the diameter of the spherical connecting block is larger than the groove opening diameter of the spherical groove.

[0011] The present invention is further configured such that: the connecting component one includes: a friction fixing plate fixedly connected to the inner bearing of the deep groove ball bearing, and a rotating fixing plate fixedly connected to the connecting surface of the hind limb facing the dummy body; wherein, the friction fixing plate is provided with at least two pieces and there is a gap between them, the rotating fixing plate is in close contact with the opposite end face of the friction fixing plate, and the friction fixing plate and the rotating fixing plate are connected by a limiting bolt.

[0012] The present invention is further configured such that the deep groove ball bearing is detachably connected to the dummy body via a connecting lug and bolts fixedly connected to the outer side of the outer bearing.

[0013] The present invention is further configured such that the dummy's torso and limbs are both made of aluminum.

[0014] The present invention is further configured such that: a heat insulation layer is attached to the outer surface of the drive motor, and the heat insulation layer is configured as either an organosilicon heat insulation coating or a ceramic-based heat insulation coating.

[0015] The present invention is further configured such that: a wind power device is provided on the device support, and the air outlet of the wind power device is directed toward the heated dummy.

[0016] The present invention is further configured such that a plurality of rolling wheels are provided at the lower end of the device support.

[0017] The wide-temperature-range clothing thermal insulation performance testing device provided by this utility model has the following beneficial effects:

[0018] (1) This utility model sets up a drive motor in the body of a dummy and connects the motor to the limbs using a deep groove ball bearing. When testing the thermal insulation performance of clothing, the drive motor is started, which can drive the limbs to swing, simulating the interaction between clothing and the human body in the state of human movement. During the interaction, the structure of the clothing also affects the air circulation between the human body and the clothing, thus affecting the thermal insulation performance of clothing in real state. Taking into account the influence of the structure of clothing on the thermal insulation performance of clothing in real situation, the test data obtained is more realistic and accurate.

[0019] (2) By setting connecting ears on the outer bearing of the deep groove ball bearing and fixing it with bolts to the dummy body, this utility model facilitates the disassembly between the deep groove ball bearing and the dummy body, that is, facilitates the disassembly between the dummy body and the limbs, thereby facilitating the maintenance of the warm body dummy, reducing maintenance costs, and at the same time facilitating the storage or transportation of warm body dummy parts.

[0020] (3) The drive motor of this invention is also equipped with a heat insulation layer, thereby reducing the impact of the heat dissipated by the drive motor during operation on the overall temperature of the dummy body and improving the accuracy of the test. The dummy body and four limbs are all made of aluminum, a metal material with high thermal conductivity, which increases the rate of temperature rise or fall of the dummy body and limbs, making the difference in the thermal insulation data of the clothing obtained by the test device more obvious, thus making it easier to judge the thermal insulation performance of the clothing.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] Example: A testing device for the thermal insulation performance of clothing over a wide temperature range, such as... Figure 1 As shown, it includes: a device support 1, a control device 2 mounted on the device support 1 for controlling the operation of the test device, and a heated mannequin 3 fixedly connected to the device support 1. Referring to the prior art, the heated mannequin 3 is also equipped with a heating system and a monitoring system. When conducting a test on the warmth retention of clothing, the operation of the heating system and the monitoring system is controlled by the control device 2. After the heated mannequin 3 is heated to the set temperature, the temperature change of the mannequin is recorded and summarized in real time by the monitoring system to draw a conclusion on the warmth retention of the clothing.

[0027] like Figure 1 , Figure 2 As shown, the warm-body dummy 3 of this utility model also includes: a dummy body 31, and four limbs 32 connected to the dummy body 31 via a movable mechanism 4; the movable mechanism 4 includes: a drive motor 41 fixedly connected to the dummy body 31 by bolts, and a deep groove ball bearing 42 for connecting the limbs 32 and the dummy body 31, wherein an output gear 411 is fixedly provided at the output end of the drive motor 41; the deep groove ball bearing 42 includes: an inner bearing 421, a ball, and an outer bearing 422; wherein the inner bearing 421 and the outer bearing 422 are rotatably arranged relative to each other via the ball; a plurality of inner gears 4211 for meshing with the output gear 411 of the drive motor 41 are arrayed on the inner ring surface of the inner bearing 421; the deep groove ball bearing 42 is detachably connected to the dummy body 31 by connecting ears 4221 fixedly connected to the outside of the outer bearing 422 and bolts; the outer bearing 422 and the inner bearing 421 of the deep groove ball bearing 42 can rotate relative to the ball.

[0028] Specifically, such as Figure 1 , Figure 2 In the embodiment of this utility model shown, with this structure, after the inner bearing 421 meshes with the output gear 411 of the drive motor 41, and the outer bearing 422 is fixed to the dummy body 31, the inner bearing 421 can still be driven to rotate by the drive motor 41 through the inner gear 4211 meshing with the output gear 411 of the drive motor 41. During rotation, due to the setting of the ball, the friction force on the inner bearing 421 is extremely small, which is beneficial to the operation of the drive motor 41.

[0029] Specifically, such as Figure 1 , Figure 2In the embodiment of this invention shown, thanks to this structural design, when the test device is started, the drive motor 41 can drive the limb 32 to swing through the deep groove ball bearing 42, simulating the state of human movement. During human movement, the airflow between the clothing and the body is affected by changes in the body's movement state, and these changes also affect the clothing's heat retention. This change in airflow is also influenced by the clothing's structure. Therefore, this test method considers the impact of the clothing's structural design on its heat retention performance during use, making the conclusions regarding heat retention determined using this invention more accurate. During maintenance, simply remove the bolts that mate with the connecting lugs 4221 on the outer bearing 422, and then move the deep groove ball bearing 42 away from the drive motor 41 to separate the limb 32 from the entire dummy body 31, facilitating disassembly and storage.

[0030] like Figure 1 , Figure 2 As shown, a connecting component 1 is fixedly connected to one end of the inner bearing 421 facing the limb 32, and the limb 32 is connected to the inner bearing 421 through the connecting component 1. The connecting component includes: a friction fixing plate 4212 welded and fixed to the inner bearing 421 of the deep groove ball bearing 42; and a rotating fixing plate 3211 welded and fixed to the connecting surface of the hind limb 321 facing the dummy body 31. At least two friction fixing plates 4212 are provided with a gap between them. The rotating fixing plate 3211 is in close contact with the opposite end face of the friction fixing plate 4212. The friction fixing plate 4212 and the rotating fixing plate 3211 are connected by a limiting bolt. The friction fixing plate 4212 and the rotating fixing plate 3211 are in close contact, generating a large frictional force between them. This ensures that when the limb 32 is driven by the drive motor 41 to swing in an azimuth angle to simulate human movement, the limb 32 is restricted to a fixed position in the pitch angle under the action of friction, making the simulated human movement of the warm-body dummy 3 more realistic, and the conclusions on the warmth retention of the clothing more consistent with reality, thus improving the accuracy of the experiment.

[0031] like Figures 1-3 As shown, the limb 32 includes: a hind limb 321 connected to the inner bearing 421 via a connecting component one, and a forelimb 322 connected to the hind limb 321 via a connecting component two; the hind limb 321 and the forelimb 322 can rotate relative to each other, and the connection angle between the forelimb 322 and the hind limb 321 can be set to better conform to the real movement state of the human body, thereby making the conclusion of the clothing warmth test more accurate.

[0032] like Figures 1-3As shown, the second connecting component includes: a spherical connecting block 3222 welded and fixed to the connecting surface of the hind limb 321 facing the forelimb 322; and a spherical groove 3221 formed on the connecting surface of the forelimb 322 facing the hind limb 321. The spherical connecting block 3222 matches the spherical groove 3221, and the diameter of the spherical connecting block 3222 is larger than the groove diameter of the spherical groove 3221. There is a large friction between the spherical groove 3221 and the spherical connecting block 3222. This friction ensures that the forelimb 322 and the hind limb 321 will not shift without additional force applied to the forelimb 322 or the hind limb 321. This ensures that when the drive motor 41 drives the limb 32 to swing as a whole, the connection angle between the forelimb 322 and the hind limb 321 remains at a set angle, thereby realistically simulating the human body's walking, running, and other movement states, and further ensuring the accuracy of the clothing's warmth retention test.

[0033] like Figure 1 , Figure 2 As shown, both the dummy body 31 and limbs 32 are made of aluminum, a metal material with high thermal conductivity. This increases the rate at which the dummy body 31 and limbs heat up or dissipate heat, making the difference in the clothing's warmth retention data obtained from the test device more obvious, thus making it easier to judge the clothing's warmth retention performance. At the same time, a heat insulation layer is attached to the outer surface of the drive motor 41. The heat insulation layer is set as either an organosilicon heat insulation coating or a ceramic-based heat insulation coating. By setting the heat insulation layer, the influence of the heat generated by the drive motor 41 during operation on the test results is reduced, thereby improving the accuracy of the test.

[0034] like Figure 1 As shown, a wind power device 5 is installed on the device support 1. The air outlet of the wind power device 5 is set towards the warm body dummy 3 to simulate the warmth performance of clothing under wind conditions on an outdoor human body, thereby improving the accuracy of the test. Several rolling wheels are installed at the lower end of the device support 1 to facilitate the overall transportation and displacement of the test device.

[0035] Working principle: When this utility model is started, the drive motor 41 runs, and the inner gear 4211 meshing with the output gear 411 drives the inner bearing 421 of the deep groove ball bearing 42 to rotate. The rotation of the inner bearing 421, through the interaction of the friction fixing plate 4212 fixedly connected to the inner bearing 421 and the rotating fixing plate 3211 fixedly connected to the hind limb 321, drives the limb 32 to swing, simulating the human body movement state. The outer bearing 422 of the deep groove ball bearing 42 is fixed to the dummy body 31 through the connecting ear 4221, thereby ensuring the connection stability of the limb 32 when it swings under the drive motor 41. In addition, thanks to the friction between the friction fixing plate 4212 and the rotating fixing plate 3211 and the friction between the spherical connecting block 3222 and the groove surface of the spherical groove 3221, the forelimb 322 and the hind limb 321 are kept at the set connection angle when the limb 32 swings, so as to further simulate the posture of human movement more realistically and obtain more accurate clothing warmth test data.

[0036] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
