DETAILED DESCRIPTION

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] Embodiment 1

[0038] Please refer to Figures 1-4 , the present application provides the following technical scheme:

[0039] A seat headrest detection device, comprising:​

[0040] The detection table 1 is fixedly connected with four fixed sleeves 3 at the top end, two of the fixed sleeves 3 are rotatably connected with lead screws 4, the other two fixed sleeves 3 are fixedly connected with first limiting rods 13, one of the fixed sleeves 3 on the left side is fixedly connected with a motor 6 at the rear end, the top end of the detection table 1 is fixedly connected with a second measuring probe 15, and the upper side of the detection table 1 is provided with a first measuring probe 11;

[0041] The clamping plates 17 are provided with two clamping plates 17, and the two clamping plates 17 are respectively sleeved on the outer surfaces of the motor 6 and the first limiting rod 13;

[0042] The pressure sensor 18 is fixedly connected to the front end of one of the clamping plates 17; and

[0043] The positioning mechanism is arranged on the upper side of the detection table 1, and is used for clamping the seat headrest body 8.

[0044] In the specific embodiment of the utility model, the detection table 1 is used as the basic support structure of the whole detection tool, provides an installation platform for other components, and ensures the relative position stability of each component in the detection process.

[0045] The fixed sleeve 3 fixes the lead screw 4 and the first limiting rod 13, so that they maintain a stable position, and at the same time provides rotary support for the lead screw 4, to ensure that the lead screw 4 can normally rotate to realize the corresponding function.

[0046] The lead screw 4 cooperates with the motor 6 and rotates under the driving of the motor 6, and through the lead screw 4 transmission principle, drives the clamping plate 17 sleeved thereon to move along the axial direction of the lead screw 4, so as to realize the accurate adjustment of the position of the clamping plate 17, to adapt to the detection requirements of seat headrests of different sizes.

[0047] The first limiting rod 13 provides a guiding action for the movement of the clamping plate 17, so that the clamping plate 17 can only move along the axial direction of the first limiting rod 13, to ensure the linearity and stability of the movement of the clamping plate 17, and at the same time limits the movement range of the clamping plate 17, to prevent damage or detection error caused by excessive movement.

[0048] The motor 6 serves as a power source and provides power for the rotation of the lead screw 4, and through controlling the forward and reverse rotation and the rotating speed of the motor 6, the rotating direction and speed of the lead screw 4 can be accurately controlled, to realize the accurate control of the moving position and speed of the clamping plate 17.

[0049] The second measuring probe 15 is used for measuring the related size or parameter of the seat headrest body 8, and feeds back the measurement data to the detection system, so as to evaluate the quality and performance of the seat headrest.

[0050] The first measuring probe 11 cooperates with the second measuring probe 15 to measure the seat headrest body 8 from different angles or positions, so as to obtain more comprehensive measurement data and improve the accuracy and reliability of detection.

[0051] The two clamping plates 17 are oppositely arranged and can move close to or away from each other under the action of the lead screw 4 and the first limiting rod 13, so as to clamp or loosen the seat headrest body 8, thereby ensuring that the seat headrest body 8 remains in a stable position during detection and facilitating various detections.

[0052] The pressure sensor 18 monitors the pressure applied by the clamping plate 17 to the seat headrest body 8 in real time and feeds back the pressure data to the detection system. By setting a suitable pressure threshold, it can be ensured that the clamping force of the clamping plate 17 on the seat headrest is neither too large to damage the headrest nor too small to cause the headrest to loosen during detection, thereby ensuring the accuracy of the detection results.

[0053] The positioning mechanism is used to accurately clamp and position the seat headrest body 8, so that the headrest is in the correct detection position on the detection table 1, ensuring the positional consistency of the headrest during each detection, thereby improving the reliability and comparability of the detection results, and preventing the headrest from shifting or shaking during detection, which affects the detection accuracy.

[0054] It should be noted that the specific model of the intelligent controller 23 used with the first measuring probe 11 and the second measuring probe 15 is selected by a person skilled in the art, and the above description of the intelligent controller 23, the first measuring probe 11 and the second measuring probe 15 all belong to the prior art, which will not be described here.

[0055] For details, please refer to Figures 1-4 , the positioning mechanism comprises:

[0056] The nut 5 is provided with two nuts 5, and the two nuts 5 are fixed in the two clamping plates 17. The two nuts 5 are threadedly connected to the circumferential surface of the lead screw 4, and the two nuts 5 are threadedly connected to the circumferential surface of the lead screw 4 in opposite directions. When the lead screw 4 rotates clockwise, it will drive the two nuts 5 to move close to each other, and vice versa.

[0057] The arc-shaped clamps 12 are provided with two arc-shaped clamps 12, and the two arc-shaped clamps 12 are arranged on the upper side of the detection table 1.

[0058] The limiting hole 16 is provided with four limiting holes 16, and the four limiting holes 16 are arranged on the top end of the detection table 1. The four second limiting rods 20 are slidably connected in the four limiting holes 16, and the four second limiting rods 20 are fixedly connected to the bottom ends of the two arc-shaped clamps 12.

[0059] The four springs 21 are fixedly connected to the bottom ends of the two arc-shaped clamps 12 respectively, and the other ends of the four springs 21 are fixedly connected to the top end of the detection table 1.

[0060] The adjusting assembly is arranged on the upper side of the detection table 1, and is used for adjusting the position height of the first measurement probe 11.

[0061] In the embodiment, the two nuts 5 are fixed in the clamping plates 17 and are threadedly connected with the lead screw 4, and one is positive and the other is reverse. This design can accurately control the opening and closing of the clamping plates 17 when the lead screw 4 rotates. When the lead screw 4 rotates clockwise, the nut 5 moves close, drives the clamping plate 17 to clamp the seat headrest; when the lead screw 4 rotates counterclockwise, the nut 5 moves reversely, and the clamping plate 17 loosens, which is convenient for replacing the detection headrest and meets the clamping requirements of headrests of different sizes.

[0062] The two arc-shaped clamps 12 are oppositely arranged on the upper side of the detection table 1, and are used for directly clamping the seat headrest body 8. The arc shape is matched with the shape of the headrest, increases the contact area, improves the clamping stability, and prevents the headrest from moving or shaking during detection.

[0063] The four limiting holes 16 on the top end of the detection table 1 provide sliding tracks for the second limiting rod 20. By limiting the moving direction of the second limiting rod 20, the arc-shaped clamp 12 can only slide axially up and down along the limiting hole 16, so as to ensure the linearity and stability of the upward and downward movement of the arc-shaped clamp 12.

[0064] The second limiting rod 20 is fixed at the bottom end of the arc-shaped clamp 12, and the other end slides in the limiting hole 16, which guides the movement of the arc-shaped clamp 12 and ensures its vertical upward and downward movement. At the same time, the moving range of the arc-shaped clamp 12 is limited, which prevents it from moving excessively and separating from the detection table 1 or affecting the detection accuracy.

[0065] The spring 21 is connected between the bottom end of the arc-shaped clamp 12 and the top end of the detection table 1. When the seat headrest body 8 is clamped, the spring 21 is compressed to generate an upward elastic force, so that the arc-shaped clamp 12 always maintains a certain pressure on the seat headrest, thereby enhancing the clamping stability. The elasticity of the spring 21 can also buffer to avoid damaging the headrest due to excessive clamping force.

[0066] The adjusting assembly is arranged on the upper side of the detection table 1, and is used for adjusting the position height of the first measurement probe 11. By flexibly adjusting the height of the first measurement probe 11, it is adapted to seat headrest bodies 8 of different sizes, measures from a suitable position, obtains more accurate measurement data, and improves the detection accuracy and reliability.

[0067] For details, please refer to Figures 1-3 The adjusting assembly comprises:

[0068] The plurality of positioning holes 7 are arranged on the top end of the detection table 1.

[0069] Screw rod 9, screw rod 9 is screwed into one of the positioning holes 7;

[0070] Adjusting plate 10, adjusting plate 10 is screwed on the circumferential surface of screw rod 9, and the first measuring probe 11 is fixedly connected to the top end of the adjusting plate 10.

[0071] In this embodiment, the positioning holes 7 are evenly arranged at the top end of the detection table 1, providing different installation position options for the screw rod 9. By screwing the screw rod 9 into different positioning holes 7, the horizontal position of the first measuring probe 11 on the detection table 1 can be preliminarily determined to adapt to the measurement requirements of different sizes and shapes of seat headrests during detection.

[0072] The screw rod 9 is screwed with the positioning hole 7 to realize its fixation on the detection table 1; on the other hand, it is also screwed with the adjusting plate 10, and by rotating the screw rod 9, the adjusting plate 10 can be driven to move up and down along the axial direction of the screw rod 9, thereby accurately adjusting the height of the first measuring probe 11.

[0073] The adjusting plate 10 is fixedly connected with the first measuring probe 11 and moves up and down under the drive of the screw rod 9, thereby changing the height position of the first measuring probe 11. The adjusting plate 10 plays a role in bearing and transmitting motion, ensuring that the first measuring probe 11 can be accurately moved to the required measurement height.

[0074] For details, please refer to Figure 2 The proximal ends of the two clamping plates 17 are fixedly connected with plastic plates 19.

[0075] In this embodiment, when the clamping plate 17 is driven by the lead screw 4 to clamp the seat headrest body 8, the plastic plate 19 plays a role in buffering and protection. Since the plastic plate 19 is soft in texture, on the one hand, it can avoid direct contact between the clamping plate 17 and the seat headrest, causing surface scratching or damage; on the other hand, it can increase the friction between the seat headrest, making the clamping more stable, preventing the seat headrest from sliding during detection, and ensuring the accuracy of the detection results. At the same time, when the lead screw 4 drives the nut 5 and the clamping plate 17 to move, the plastic plate 19 can move synchronously with the clamping plate 17, tightly cooperating to complete the clamping action of the seat headrest.

[0076] For details, please refer to Figures 1-4 The rear end of the detection table 1 is fixedly connected with an intelligent controller 23, and the intelligent controller 23 is electrically connected with the first measuring probe 11 and the second measuring probe 15.

[0077] In the embodiment, the intelligent controller 23 serves as the core control unit of the entire detection system, playing a key role in coordination and management. It is electrically connected with the first measurement probe 11 and the second measurement probe 15, and can receive the measurement data of the seat headrest body 8 collected by the two measurement probes in real time, such as size, shape parameters, etc. Based on the preset detection standards and algorithms, the intelligent controller 23 quickly analyzes and processes these data to determine whether the seat headrest meets the quality requirements. At the same time, the operator can pre-set the detection parameters, such as the measurement range and accuracy requirements, through the intelligent controller 23, and the intelligent controller 23 controls the working state of the measurement probe according to these settings to ensure the accuracy and consistency of the measurement work.

[0078] For details, please refer to Figures 1-3 The bottom end of the detection table 1 is fixedly connected with the first plastic pad 2, and the outer surface of the four second limiting rods 20 is fixedly connected with the limiting block 14.

[0079] In the embodiment, the first plastic pad 2 at the bottom end of the detection table 1 continuously plays an important role in shock absorption and anti-skid during the entire detection tool working process, and the limiting block 14 strictly limits the movement range of the arc-shaped clamp 12 to prevent excessive movement. This not only ensures the stable clamping of the arc-shaped clamp 12 on the seat headrest, but also avoids damaging related components due to excessive movement of the arc-shaped clamp 12.

[0080] For details, please refer to Figures 1-4 The outer surface of the screw rod 9 is fixedly connected with the second plastic pad 22.

[0081] In the embodiment, the second plastic pad 22 is used to limit the height position of the screw rod 9 to prevent the screw rod 9 from moving excessively downward at the predetermined position, affecting the detection effect.

[0082] The working principle and use process of the utility model are as follows: when detecting the seat headrest, first, the seat headrest body 8 to be detected is placed on the detection table 1, and the detection parameters such as the measurement range and the accuracy requirement are set in advance through the intelligent controller 23. Then, the motor 6 is started, the motor 6 drives the screw rod 4 to rotate, the two nuts 5 on the screw rod 4 are respectively connected in the forward and reverse threads and are fixed in the two clamping plates 17, when the screw rod 4 rotates clockwise, the nut 5 drives the clamping plate 17 to move close to each other and clamp the headrest, and when the screw rod 4 rotates counterclockwise, the nut 5 drives the clamping plate 17 to loosen, in the process, the first limiting rod 13 is used for guiding and limiting the movement range of the clamping plate 17. The plastic plate 19 on the clamping plate 17 is used for buffering protection and increasing the friction force, so that the headrest is prevented from being scratched and sliding. At the same time, the two arc-shaped clamps 12 cooperate with the clamping plate 17 to clamp the headrest, the arc-shaped design increases the contact area and improves the clamping stability, the limiting hole 16 and the second limiting rod 20 limit the arc-shaped clamp 12 to slide up and down only, the movement stability of the arc-shaped clamp 12 is ensured and the range is limited, the spring 21 is compressed to generate elastic force, and the clamping stability is further improved. Then, according to the size and shape of the headrest, the appropriate positioning hole 7 is selected and screwed into the screw rod 9, the horizontal position of the first measurement probe 11 is preliminarily determined, the screw rod 9 is further rotated to drive the adjusting plate 10 and the first measurement probe 11 to move up and down, the height is accurately adjusted, the second plastic pad 22 outside the screw rod 9 is used for preventing sliding and preventing excessive downward movement. Then, the first measurement probe 11 and the second measurement probe 15 measure the headrest from different angles and positions, and obtain the size, shape and mounting hole data, the pressure sensor 18 monitors the pressure applied by the clamping plate 17 to the seat headrest body 8 in real time and feeds back, so that the detection result is accurate, the measurement data is transmitted to the intelligent controller 23, the intelligent controller 23 analyzes and processes the data according to the preset standard and algorithm, and whether the headrest is qualified is judged.
