Referring to fig. 1, the testing device of the present application includes a bracket 11, a base 17, a fixing base 12, and a sensor 13. The bracket 11 can be used for placing the fixed seat 12 and also can be used for placing other testing components, and for the whole testing device, the bracket 11 can play a role in supporting and fixing other components. The base 17 can be used for a tester to sit on to facilitate the tester to perform a test action of the forward bending of the sitting body. The fixing base 12 is used for placing the sensor 13 for detecting the hand position of the tester, and meanwhile, the tester can also pass through the position, the height and the like of the fixing base 12, so that the tester can adjust the position of the tester according to the fixing base 12, and the tester can better test the hand position. The sensor 13 detects the hand position of the tester, and obtains the test result of the tester by detecting the hand position of the tester and then performing conversion.

The bracket 11 is used for supporting and fixing other components. Specifically, the bracket 11 may be plate-shaped, and other components may be disposed on the bracket 11, for example, at an edge of the bracket 11, or in the bracket 11, and a through hole penetrating through two opposite sides of the bracket 11 may also be formed on the bracket 11, so as to facilitate mounting and fixing of the other components. In some embodiments, the support 11 may also be other shapes, such as a parallelogram shape, etc. The bracket 11 may be formed by integrally molding a single piece of material, or by splicing a plurality of components. Of course, a groove or other structure may be provided at the edge or inside of the bracket 11 to facilitate the fixing of other components on the bracket 11 and the embedding of the line.

The base 17 may be provided at one end of the bracket 11. The base 17 is used to support a tester so that the tester can sit thereon to perform a relevant test. Meanwhile, by arranging the base 17, the support 11 can be vertically placed relative to the ground by virtue of the base 17, and the base 17 plays a role in fixing the support 11. In some embodiments, other components may be disposed on the base 17 to facilitate other tests for the tester, such as installing a pressure sensor, and measuring the bounce ability of the tester by calculating the vacated time of the tester after the tester jumps up by standing on the pressure sensor.

When the seat body forward bending test is performed, an auxiliary component can be arranged on the base 17, so that a tester can fix the position of the tester conveniently, and the test can be performed better. For example, the testing device described in this embodiment further includes a T-shaped hook 18, which is disposed adjacent to the connecting position of the base 17 and the bracket 11, for maintaining the position of the foot of the tester. The T-hook foot portion 18 includes a vertical post 181 and a cross post 182. One end of the upright column 181 may be fixed on the base 17 and adjacent to the connecting position of the base 17 and the bracket 11, and the other end of the upright column 181 may be used to fixedly connect the cross column 182, and the extending direction of the cross column 182 is perpendicular to the upright column 181 and parallel to the bracket. When the tester sits on the base 17, the feet can hook the cross column 182 of the T-shaped hook foot 18 and contact the bracket 11, so as to fix the position of the feet by using the cross column 182. In the test, since the sole thickness of each person is not uniform, when the cross pillar 182 is too far away from the bracket 11, the foot of the person does not necessarily contact the bracket 11, and therefore, in another embodiment, the T-shaped hook 18 is movable relative to the base 17, and specifically, the upright 181 is connected to the base 17 through a locking mechanism. The T-shaped hook foot part 18 with the adjustable distance can enable a tester to be more convenient during testing, and moreover, the distance is adjustable, so that each tester can use the T-shaped hook foot part 18 to fix the position of the foot part and simultaneously contact the support 11, and the testing result can be more accurate. In other embodiments, the outer surfaces of the upright column 181 and the cross column 182 may be covered with an elastic member, such as a sponge, to prevent the feet of the tester from being in hard contact with the upright column 181 and the cross column 182, so that the tester may be injured.

The fixing seat 12 is disposed on the support 11, and penetrates through two opposite sides of the support 11, and the base 17 may be disposed at an interval from the fixing seat 12. When a tester faces the bracket 11 and sits on the base 17, the tester can measure the forward bending result of the sitting body through the fixed seat 12. Specifically, a plurality of sensors 13 may be provided at the holder 12 to detect the hand position of the tester. For example, the plurality of sensors 13 may be disposed on the fixing base 12 at intervals along a preset direction, and configured to detect a position where a hand of a tester extends onto the fixing base 12 along the preset direction when the tester performs a test. The predetermined direction may be an extending direction of the base and is perpendicular to the cross-post 182. It can be understood that when the tester performs the seat forward bending test and sits on the base 17, the two feet will hook the cross pillar 182 of the T-shaped foot hooking portion 18, and the two feet are perpendicular to the cross pillar 182, and the tester can measure the seat forward bending result by moving the hands toward the extending direction of the feet. Therefore, when the predetermined direction is the extending direction of the base and is perpendicular to the cross-post 182, the extending direction of the foot of the tester is the same as the predetermined direction, which is convenient for the tester to test.

In addition, since each tester has a different height and the height of the fixing base 12 matched with the tester is different, for example, if the height of the fixing base 12 suitable for the tester with the height of 180 cm is 50 cm, and the height of the fixing base 12 suitable for the tester with the height of 165 cm is 30 cm, the measured forward bending result of the sitting position body may not be accurate if the tester cannot move the hands of the tester in the direction parallel to the extending direction of the feet of the tester. Therefore, in other embodiments, the distance between the fixed seat 12 and the base 17 is adjustable, and the fixed seat is arranged on the bracket 11 through a locking mechanism. When the height of the fixing seat 12 is adjustable, the height of the fixing seat 12 can be correspondingly adjusted according to people with different heights, and then the test result can be more accurate.

Referring to fig. 1 and 2, the fixing base 12 may be formed with an accommodating groove 121 extending along a predetermined direction, and the plurality of sensors 13 are disposed in the accommodating groove 121 at intervals for detecting a position where a hand of a tester extends into the accommodating groove 121. Specifically, the fixing base 12 may be integrally formed, and the accommodating groove 121 is formed in the fixing base 12, and may also be formed by connecting and combining other components, for example, the fixing base 12 in this embodiment may further include an arc plate 122 and a hand touch plate 123, and the hand touch plate 123 and the arc plate 122 may cooperate to form the accommodating groove 121. When the plurality of sensors 13 are disposed on the fixing base 12 at intervals along the predetermined direction, the plurality of sensors 13 may be disposed in the accommodating groove 121 at intervals for detecting the position of the hand of the tester extending into the accommodating groove 121.

In this embodiment, the hand position of the tester is detected by the sensor 13. Referring to fig. 2, 3 and 4, the sensor 13 may specifically include an optical signal emitting element 131 and an optical signal receiving element 132, the optical signal emitting element 131 is used for emitting the test optical signal, and the optical signal receiving element 132 is used for receiving the test optical signal to detect the position of the hand of the tester when the hand of the tester blocks the optical signal. Specifically, the test light signal may be infrared light, the light signal emitting element 131 may be an infrared emitting element, and the light signal receiving element 132 may be an infrared receiving element. During testing, when the testing optical signal emitted by the optical signal emitting element 131 is shielded by a hand, since the optical signal receiving element 132 cannot receive the testing optical signal, the hand of the tester can be considered to be located on the propagation path of the testing optical signal, and then the hand position of the tester is obtained through conversion by the position of the optical signal emitting element 131 or the optical signal receiving element 132. If the distance between the optical signal emitting part 131 and the optical signal receiving part 132 of one of the sensors 13 is 5 cm with respect to the frame 11, when the optical signal receiving part 132 does not receive the test optical signal due to the shielding of the tester's hand, it can be considered that the distance between the tester's hand and the frame 11 is at least 5 cm. Then, the sensor 13 that has not received the test light signal, which is the farthest distance from the holder 11, can be regarded as the test result of the tester. When the distances between the optical signal emitting element 131 and the optical signal receiving element 132 are not equal to each other with respect to the bracket 11, the test result of the tester can also be obtained through conversion, and the description is omitted here.

The position of the hand of the tester is detected through the sensor 13, so that the hand of the tester can be tested without contacting with the testing device, the achievement is avoided, the operation that the tester needs to actively push a hand push plate in the past test is avoided, the whole testing process is easier and more convenient, the accuracy is high, and the testing precision is improved by utilizing the sensor 13 to detect the position of the hand.

Referring to fig. 3 and 4, the optical signal emitting element 131 further includes an emitting surface 1311, and the optical signal receiving element 132 further includes a receiving surface 1322. In order to facilitate the detection of the hand position of the tester, the emitting surface 1311 of the optical signal emitting element 131 and the receiving surface 1322 of the optical signal receiving element 132 of the sensor 13 may be disposed opposite to each other and located at two opposite sides of the accommodating groove 121, respectively, so that the test optical signal may be emitted from one side of the accommodating groove 121 to the other side opposite thereto. Specifically, the optical signal emitting element 131 and the optical signal receiving element 132 may be disposed at or adjacent to the connection positions of the hand touch plate 123 and the arc plate 122, respectively. When the optical signal emitting and receiving parts 131 and 132 are adjacently disposed at the connection position of the hand touch plate 123 and the arc plate 122, the optical signal emitting and receiving parts 131 and 132 may be installed on the hand touch plate 123 or the arc plate 122, and are adjacent to the connection position of the hand touch plate 123 and the arc plate 122. When the hand of the tester is inserted into the receiving cavity 121, the testing optical signal is blocked, and the hand position of the tester is detected to obtain the testing result.

Referring to fig. 2, 3 and 4, in order to enable the sensor 13 to be more conveniently disposed in the receiving groove 121, a mounting component for mounting the sensor 13 may also be disposed in the receiving groove 121, for example, the testing device described in this embodiment may further include a first mounting component 14 and a second mounting component 15, and the first mounting component 14 and the second mounting component 15 are respectively disposed at the connection position of the hand touch plate 123 and the arc plate 122. The optical signal emitting parts 131 are spaced apart from each other at the first mounting part 14, and the optical signal receiving parts 132 are spaced apart from each other at the second mounting part 15. By using the first and second mounting members 14 and 15, the sensor 13 can be pre-mounted on the mounting members and integrated, such as uniformly wiring, determining the distance between the light signal emitting members 131 and the distance between the light signal receiving members 132, so that the modularization degree of the whole testing device is improved, the mounting is convenient, and the replacement is also convenient in case of damage of the sensor 13. In order to improve the accuracy of the test, the smaller the distance between the optical signal emitting parts 131 and the distance between the optical signal receiving parts 132, the higher the accuracy, and in this embodiment, the distance between them may be in the range of 0.5-2 mm, and in one embodiment, the distance may be 1 mm.

In other embodiments, the side of the first mounting groove 1411 opposite to the emitting surface 1311 and the side of the second mounting groove 1511 opposite to the receiving surface 1322 may be provided with an opening, so that the test optical signal may reach the optical signal receiving member through the opening. Of course, the opening may also be sized to be an entire side.

In order to improve the test sensitivity of the sensor 13, the longer the distance between the first mounting member 14 and the second mounting member 15 is, the longer the propagation path of the test optical signal is, the more easily the hand of the subject is blocked, and the greater the test sensitivity of the sensor 13 is. In the present embodiment, the first mounting part 14 and the second mounting part 15 may be disposed at two ends of the fixing base 12, and specifically, may be disposed at the connection positions of the hand touch plate 123 and the arc plate 122 of the fixing base 12, respectively, so that the propagation path of the test optical signal is longer. In this embodiment, the first mounting part 14 and the second mounting part 15 may be respectively disposed at the connection position of the hand touch plate 123 and the arc-shaped plate 122, and a part of the first mounting part 14 is fixedly connected with the arc-shaped plate 122, and another part is fixedly connected with the hand touch plate 123. In other embodiments, the first mounting component 14 and the second mounting component 15 can also be disposed on the hand touch plate 123 or the arc plate 122, and are adjacent to the connection position of the hand touch plate 123 and the arc plate 122.
