[0029] The present invention provides a door detection device 100.

[0030] In the embodiment of the present invention, as Figures 1 to 4 shown, the door detection device 100 includes: a base body 110, a first laser sensor 120, and a second laser sensor 130. The first laser sensor 120 is fixedly arranged in the base body 110, and the first laser sensor 120 is used to emit and receive a first detection laser outside the base body 110; the second laser sensor 130 is fixedly arranged in the base body 110, and the second laser sensor 130 is used to emit and receive a second detection laser outside the base body 110; wherein, the detection range of the first laser sensor 120 is smaller than the detection range of the second laser sensor 130.

[0031] Specifically, the first laser sensor 120 and the second laser sensor 130 are sensors that use laser technology for measurement. Generally, they consist of a laser emission end, a laser reception end, and a measurement circuit. They can achieve non-contact long-distance measurement, with fast speed, high accuracy, large measurement range, strong resistance to light and electrical interference, etc. When measuring the distance, after the laser is emitted towards the target, its round-trip time is measured, and then multiplied by the speed of light to obtain the round-trip distance. Taking the first laser sensor 120 as an example, the detection end of the first laser sensor 120 includes a first emission end and a first reception end. The first emission end emits a first detection laser outside the base body 110. After the first detection laser reaches the target object (the car door 210, the retroreflector, or the vehicle body 200), it is reflected back and received by the first reception end, thus realizing the distance measurement function. Among them, for the convenience of the emission and reception of the first detection laser and the second detection laser, openings can be correspondingly provided on the base body 110.

[0032] It should be noted that the detection direction of the first laser sensor 120 here refers to the direction towards which the detection end of the first laser sensor 120 faces, that is, the extension direction of the symmetry center line between the first detection laser emitted by the first laser sensor 120 and the first detection laser received; similarly, the detection direction of the second laser sensor 130 here refers to the direction towards which the detection end of the second laser sensor 130 faces, that is, the extension direction of the symmetry center line between the second detection laser emitted by the second laser sensor 130 and the second detection laser received. In this embodiment, for the convenience of positioning and measurement, the first laser sensor 120 and the second laser sensor 130 can be arranged side by side, and the detection ends of the first laser sensor 120 and the second laser sensor 130 can be set to face the same direction.

[0033] The door detection device 100 of the present invention can measure data on relevant dimensional indicators of the vehicle door 210. During measurement, the door detection device 100 of the present invention is positioned at the measurement point of the vehicle door 210, and distance measurements are carried out by the first laser sensor 120 and the second laser sensor 130, so as to obtain relevant measurement data. The items that can be measured by the door detection device 100 of the present invention at least include: the V-degree of the vehicle door 210, the centering dimension of the vehicle door 210, the distance between the outer surface of the vehicle door 210 and the vehicle body 200, the opening degree of the vehicle door 210, the extrusion width of the sealing strip, etc. Among them, the V-degree of the vehicle door 210 refers to the distance difference between the opening width distance at 200 mm from the upper part to the lower part after the vehicle door 210 is opened a certain distance to the left and right and the opening width distance at 200 mm from the lower part to the upper part of the vehicle door 210; the centering dimension of the vehicle door 210 refers to the error value between the actual center distance of the vehicle door 210 during the closing or opening process and the absolute center value of the vehicle door 210 frame; the distance between the outer surface of the vehicle door 210 and the vehicle body 200 refers to the distance from the outer surface of the vehicle door 210 to the outside of the vehicle body 200 after the vehicle door 210 is opened; the opening degree of the vehicle door 210 refers to the width distance at the upper and lower centers of the vehicle door 210 after the vehicle door 210 is fully opened; the extrusion width of the sealing strip refers to the width distance of the surfaces of the left and right vehicle doors 210 where the sealing strips are installed when the vehicle door 210 is in the closed state.

[0034] The specific measurement method is as follows: As Figure 5 shown, three positions at the upper, middle, and lower parts of the left edge of the vehicle door 210 are selected as measurement points, which are respectively defined as measurement point a, measurement point c, and measurement point e. Three positions at the upper, middle, and lower parts of the right edge of the vehicle door 210 are selected as measurement points, which are respectively defined as measurement point b, measurement point d, and measurement point f. Among them, measurement point a is opposite to measurement point b, measurement point c is opposite to measurement point d, and measurement point e is opposite to measurement point f. Positioning the door detection device 100 at measurement points a, b or c, d or e, f can directly measure the opening degree data of the vehicle door 210; positioning the door detection device 100 at measurement points a, b, c, d can directly measure the V-degree data of the vehicle door 210; positioning the door detection device 100 at measurement points c, d can directly measure the centering dimension data of the vehicle door 210 and the extrusion width data of the sealing strip. In addition, selecting the left top end of the vehicle door 210 as measurement point g and the right top end of the vehicle door 210 as measurement point h, and positioning the door detection device 100 at measurement points g, h, the distance data between the outer surface of the vehicle door 210 and the vehicle body 200 can be directly measured.

[0035] After obtaining the test data of various parameters, the test results can be compared with the range of the detection technical standard of the vehicle door 210, so as to determine whether the various parameters of the vehicle door 210 meet the standard, which is convenient for technicians to repair or replace the vehicle door 210. The vehicle door detection device 100 of the present invention can realize automatic detection, the detection method is convenient, the detection efficiency can be improved, human resources can be saved, and at the same time, the interference of human factors on the detection can be reduced, and the detection accuracy can be improved.

[0036] Among them, the detection range of the first laser sensor 120 is smaller than that of the second laser sensor 130, that is to say, the measurement interval of the first laser sensor 120 is smaller than that of the second laser sensor 130. Taking the vehicle door detection device 100 as the measurement starting point, the detection distance of the second laser sensor 130 is greater than that of the first laser sensor 120. Since the measurement accuracy of the laser sensor is affected by the size of the measurement range, when the first laser sensor 120 selects a smaller range, the detection accuracy of the first laser sensor 120 can be improved. Therefore, except for using the second laser sensor 130 to measure the distance of the relatively large dimension index of the vehicle door 210 opening degree, the other vehicle door 210 dimension indexes (including the V-degree of the vehicle door 210, the centering dimension of the vehicle door 210, the distance between the vehicle door 210 and the outer surface of the vehicle body 200, the sealing strip extrusion width, etc.) can all use the first laser sensor 120 to measure the distance. In this way, the first laser sensor 120 with a smaller detection range and the second laser sensor 130 with a larger detection range are used in combination. The first laser sensor 120 can meet the measurement ranges of the V-degree of the vehicle door 210, the centering dimension of the vehicle door 210, the distance between the vehicle door 210 and the outer surface of the vehicle body 200, and the sealing strip extrusion width, and the measurement accuracy of the first laser sensor 120 is high, and more accurate measurement data can be obtained. The detection range of the second laser sensor 130 is larger and can be suitable for measuring the relatively large dimension index of the vehicle door 210 opening degree, so that the vehicle door detection device 100 of the present invention can measure various vehicle door 210 dimension indexes and obtain relatively accurate measurement data. Among them, the specific detection ranges and detection accuracies of the first laser sensor 120 and the second laser sensor 130 can be set according to actual needs, and the present invention does not limit this.

[0037] In an embodiment of the present invention, please refer to Figures 1 to 4 , an installation cavity is opened inside the base body 110, and a first opening 111 and a second opening 112 communicating with the installation cavity are opened on the surface of the base body 110; the first laser sensor 120 and the second laser sensor 130 are both arranged in the installation cavity, and the first laser sensor 120 emits and receives the first detection laser through the first opening 111, and the second laser sensor 130 emits and receives the second detection laser through the second opening 112.

[0038] In this embodiment, the base body 110 is generally in a rectangular shape and has a hollow structure. The first laser sensor 120 and the second laser sensor 130 are installed in the installation cavity of the base body 110. The detection end of the first laser sensor 120 is aligned with the first opening 111, and the detection end of the second laser sensor 130 is aligned with the second opening 112. By providing the first opening 111 and the second opening 112, the emission and reception of the first detection laser and the second detection laser can be facilitated. Among them, the base body 110 can not only fix the first laser sensor 120 and the second laser sensor 130 together, facilitating the arrangement of the electric control components, making the door detection device 100 form a compact whole with a small and delicate structure, which is beneficial to being held by hand and convenient to carry. At the same time, the base body 110 can also protect the first laser sensor 120 and the second laser sensor 130 from being damaged by external objects, which is beneficial to improving the durability of the product.

[0039] In an embodiment of the present invention, please refer to Figures 1 to 4 , the first laser sensor 120 and the second laser sensor 130 are arranged along the length direction of the base body 110, and the detection directions of the first laser sensor 120 and the second laser sensor 130 are the same.

[0040] In this embodiment, the base body 110 is generally in a rectangular shape. The first laser sensor 120 and the second laser sensor 130 are arranged in sequence along the length direction of the base body 110. Moreover, the first opening 111 and the second opening 112 are provided on the same surface of the base body 110. That is to say, the detection ends of the first laser sensor 120 and the second detection sensor face the same direction, and the first detection laser and the second detection laser are emitted and received from the same surface of the base body 110. With such an arrangement, when using the door detection device 100, after the staff positions the base body 110 on the car door 210, the first laser sensor 120 or the second laser sensor 130 can be arbitrarily selected for use according to needs. This detection method is convenient and beneficial to improving the detection efficiency. If the detection directions of the first laser sensor 120 and the second laser sensor 130 are different, that is, the first detection laser and the second detection laser are emitted and received from different surfaces of the base body 110, then every time the first laser sensor 120 or the second laser sensor 130 is switched for use, the base body 110 needs to be repositioned, which will make the detection steps cumbersome and thus reduce the detection efficiency.

[0041] In an embodiment of the present invention, please refer to Figures 1 to 4, a first reference plane 113 is formed on a surface of the base body 110 parallel to the detection direction of the first laser sensor 120; the base body 110 is positioned on the vehicle door 210 through the first reference plane 113, so that the detection direction of the first laser sensor 120 is parallel to the surface of the vehicle door 210.

[0042] In this embodiment, the base body 110 is generally in a rectangular shape, the first opening 111 and the second opening 112 are located on the same surface of the base body 110, that is, the detection directions of the first laser sensor 120 and the second detection direction are the same. Taking the surface where the first opening 111 and the second opening 112 are located on the base body 110 as the working surface, then the side surfaces (perpendicular to the working surface) on the left and right sides of the base body 110 in the working surface can both be used as the first reference plane 113. When using the vehicle door detection device 100 to measure the V-degree of the vehicle door 210, the centering dimension of the vehicle door 210, the opening degree of the vehicle door 210 or the extrusion width of the sealing strip, the base body 110 can be attached to the surface of the vehicle door 210 through the first reference plane 113, and the working surface is oriented towards the opposite vehicle door 210. In this way, the first laser sensor 120 can accurately emit the first detection laser towards the opposite vehicle door 210 (or the retroreflector located on the opposite vehicle door 210), and accurately receive the first detection laser reflected back by the opposite vehicle door 210 (or the retroreflector located on the opposite vehicle door 210). Similarly, the second laser sensor 130 can accurately emit the second detection laser towards the opposite vehicle door 210 (or the retroreflector located on the opposite vehicle door 210), and accurately receive the second detection laser reflected back by the opposite vehicle door 210 (or the retroreflector located on the opposite vehicle door 210). This technical solution can facilitate the positioning of the vehicle door detection device 100 and is also beneficial to improving the detection accuracy.

[0043] In an embodiment of the present invention, please refer to Figures 1 to 4 , the vehicle door detection device 100 further includes: a positioning member 140, the positioning member 140 is provided on a surface of the base body 110 where the first opening 111 is located, and the positioning member 140 extends along a direction parallel to the detection direction of the first laser sensor 120; wherein, a second reference plane 141 is formed on a surface of the positioning member 140 facing away from the first opening 111, and a surface of the base body 110 where the positioning member 140 is provided is divided into two regions by the positioning member 140, and the region where the first opening 111 is not provided forms a third reference plane 114; the positioning member 140 is positioned on the top surface of the vehicle door 210 through the second reference plane 141, and the base body 110 is positioned on the surface of the vehicle door 210 through the third reference plane 114, so that the detection direction of the first laser sensor 120 is perpendicular to the surface of the vehicle door 210.

[0044] In this embodiment, the base body 110 is generally in the shape of a rectangular body. The first opening 111 and the second opening 112 are located on the same surface of the base body 110, that is, the detection directions of the first laser sensor 120 and the second laser sensor 130 are the same. The positioning member 140 is a positioning block, and the positioning member 140 is generally in the shape of a rectangular body. Taking the surface of the base body 110 where the first opening 111 and the second opening 112 are located as the working surface, the positioning member 140 is arranged on the working surface of the base body 110 along the transverse direction (perpendicular to the length direction of the base body 110) and protrudes along the direction parallel to the detection direction of the first laser sensor 120. Among them, the positioning member 140 can be arranged between the first opening 111 and the second opening 112. A second reference surface 141 is formed on one side surface of the positioning member 140 facing the second opening 112. The working surface is divided into two regions by the positioning member 140 as a whole. The region where the second opening 112 is located forms a third reference surface 114. The second reference surface 141 and the third reference surface 114 are vertically connected. As Figure 6 shown, when using the door detection device 100 to measure the distance from the door 210 to the outer surface of the vehicle body 200, the positioning member 140 can be attached to the top surface of the door 210 through the second reference surface 141, and the base body 110 can be attached to the inner surface of the door 210 through the third reference surface 114, while making the working surface face the outer vehicle body 200. In this way, the first laser sensor 120 can accurately emit the first detection laser towards the vehicle body 200 and accurately receive the first detection laser reflected back by the outer vehicle body 200. This technical solution can facilitate the positioning of the door detection device 100 and is also beneficial to improving the detection accuracy.

[0045] Furthermore, the installation cavity of the base body 110 can be sequentially divided into three parts along the length direction of the base body 110. The first part is used to install the first laser sensor 120, the second part is used to install the second laser sensor 130, and the third part is used to install the electronic control components (including the control module 151, the wireless communication module 152, the battery 153, the control button 154, the charging interface 155, etc.). In this way, the structure can be made compact and the size can be small. At the same time, the base body 110 can be in a long shape, which is beneficial to the handheld grip of the base body 110 and convenient to carry. In addition, the first laser sensor 120 and the second laser sensor 130 can be respectively arranged on both sides of the positioning member 140. That is to say, the positioning member 140 is arranged between the first opening 111 and the second opening 112. With such an arrangement, the positioning member 140 can be located below the first laser sensor 120, above the second laser sensor 130 and the electronic control components, so that the part of the base body 110 corresponding to the second laser sensor 130 and the electronic control components forms a handheld part, which is convenient to grip.

[0046] In an embodiment of the present invention, the door detection device 100 further includes: a retroreflector (not shown), and the retroreflector is movable relative to the base body 110.

[0047] In this embodiment, when using the door detection device 100 to measure the V-degree of the door 210, the opening degree of the door 210, or the extrusion width of the sealing strip, since there is a lack of an object that can reflect laser light on the opposite door 210, it is difficult to achieve the measurement purpose. Therefore, a retroreflector is additionally equipped for the base body 110 and can be selected as needed. Taking the measurement of the opening degree of the door 210 as an example, first, the base body 110 is positioned on the surface of the door 210 through the first reference plane 113 (specifically, the base body 110 is positioned at the connection between the edge of the door 210 and the sealing strip), and the working surface of the base body 110 faces the opposite door 210. At the same time, the retroreflector is abutted against the surface of the opposite door 210 (specifically, the retroreflector is positioned at the connection between the edge of the door 210 and the sealing strip), and the retroreflective surface of the retroreflector faces the base body 110, making the retroreflector opposite to the base body 110. Then, distance measurement is performed through the second laser sensor 130, that is, the second detection laser emits the second detection laser and receives the second detection laser reflected back by the retroreflector, and relevant data on the opening degree of the door 210 can be obtained. By setting the retroreflector, detection can be facilitated. The above steps can be simultaneously operated by a staff member with the left hand and the right hand, with convenient operation and efficient detection.

[0048] In an embodiment of the present invention, please refer to Figures 3 to 4 , the door detection device 100 further includes: a control module 151, a wireless communication module 152, and a battery 153. The first laser sensor 120 and the second laser sensor 130 are respectively electrically connected to the control module 151; the wireless communication module 152 is electrically connected to the control module 151; the battery 153 is electrically connected to the control module 151; wherein, the control module 151, the wireless communication module 152, and the battery 153 are all disposed within the base body 110.

[0049] In this embodiment, the control module 151 and the wireless communication module 152 can be integrated on a circuit board 156. By inputting a control instruction to the control module 151, the battery 153 can be controlled to supply power to the first laser sensor 120 and the second laser sensor 130, and the first laser sensor 120 and the second laser sensor 130 can be controlled to work, so as to detect relevant data on multiple door 210 size indicators. The measured data is directly calculated by the background program to obtain the required data, without the need for manual calculation, recording, etc. The detection method is simple, efficient, and accurate, and digital and paperless detection can be achieved. In addition, wireless communication can be performed with a terminal device (such as a computer, a mobile phone, etc.) through the wireless communication module 152 (such as a Bluetooth module, a WIF module, etc.), and the detection data can be transmitted to the terminal device for convenient remote viewing and data informatization.
