Description

Technical Field

[0001] The present invention relates to the field of life support vehicle assembly, in particular to a vehicle compartment floor assembly device for a life support vehicle. Background Art

[0002] Outdoor scenarios such as disaster emergency rescue, military operations, power and communications repair require support for cooking, camping, and emergency rescue equipment to meet the needs of rescuers working in the field around the clock. Life support vehicles integrate cooking, camping, field rescue, lighting, communications, and vehicle mobility to meet the needs of all-weather field operations.

[0003] The floor of the life support vehicle Figure 1 As shown, the vehicle consists of a frame, outer panels, and inner panels. The frame serves as the primary structural support for the vehicle floor. The inner and outer panels are glued to the frame's upper and lower surfaces, respectively. After the inner and outer panels are glued to the frame, a worker gently taps the panels to expel the air between them and the frame, or uses a heavy object to press them together to ensure full contact. Conventional methods use a rubber hammer to manually perform this tapping. On the one hand, there are many hollow parts in the skeleton. If the hollow parts are knocked, the gap between the main part of the skeleton and the mask will increase. At the same time, when the vibration generated by the knocking of the hollow parts is transmitted to the space between the main part and the mask, a certain amount of air will be introduced, which makes the bonding effect between the skeleton and the mask worse. On the other hand, if the method of heavy pressing is adopted, the life support vehicle has different areas for different application scenarios, such as cooking areas, camping areas, etc. The load-bearing and working environment of different areas are different. For example, the cooking area is prone to moisture, and a stainless steel inner mask is required. The camping area generally has a lower load-bearing capacity, and an aluminum inner mask can be used. Since the thickness of the masks made of different materials is different, an auxiliary plate needs to be prepared before pressing to make the upper end surface of the mask flush.

[0004] The purpose of the present invention is to design a vehicle floor assembly device for a life support vehicle in order to solve the above problems in the prior art. Summary of the Invention

[0039] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings:

[0040] refer to Figure 3-10 , a vehicle floor assembly device for a life support vehicle, comprising:

[0041] Undertaking platform 1;

[0042] A hammer mounting frame 2, wherein the hammer mounting frame 2 is connected to the receiving platform 1 by a track so as to be reciprocating in the long side direction of the receiving platform 1;

[0043] Several hammer bodies 3 are arranged in parallel on the hammer body mounting frame 2 in a transverse direction. The hammer bodies 3 include an outer shell 301, a hammer head 302, and a linkage member. The linkage member is an airbag 303. The outer shell 301 is a cylindrical structure. The hammer head 302 is a cylindrical structure and is arranged in the outer shell 301. The bottom end of the hammer head 302 protrudes below the bottom end of the outer shell 301. A gap is set between the top of the hammer head 302 and the outer shell 301. The airbag 303 is arranged between the hammer head 302 and the outer shell 301. The airbag 303 is used to drive the hammer head 302 to move up and down to achieve a knocking action.

[0044] The hammer driving device (not shown) is used to drive the airbag 303 to inflate or deflate, thereby driving the hammer 302 to move up and down. In this embodiment, the hammer driving device is an air pump, which drives the airbag 303 to inflate or deflate.

[0045] An elastic member 304 is provided between the top of the hammer head 302 and the top of the outer shell 301 . The elastic member 304 is used to drive the hammer head 302 to return to its original position after the airbag 303 is deflated.

[0046] In this embodiment, the airbag 303 is inflated to cause the airbag 303 to move the hammer head 302 downward. The hammer head 302 needs to be repeatedly moved up and down to achieve the striking process. Therefore, the hammer head 302 needs to be quickly raised after the airbag 303 is deflated. In this embodiment, the elastic member 304 is provided to pull the hammer head 302 upward after the airbag 303 is deflated. In this embodiment, the elastic member 304 is a spring.

[0047] Furthermore, the hammer body 302 is rotated by a corresponding hammer body rotating device 6, and the bottom end of the hammer body is a long strip structure.

[0048] In this embodiment, the bottom end of the hammer body 302 is an elongated structure. The purpose is that the structure of the skeleton is generally an elongated structure. The shape of the bottom end of the hammer body 302 can adapt to the shape of each beam in the skeleton, preventing the hammer body 302 with a protruding elongated shape from hitting a position other than the beam of the skeleton during the hammering process, generating oscillation and introducing air into the surrounding glued positions.

[0049] This embodiment further rotates the hammer through the hammer rotating device 6, thereby changing the direction of the long strip structure at the lower end of the hammer 302 to make it the same as or compatible with the extension direction of each bone beam of the skeleton, thereby reducing the impact on the hollow part of the skeleton.

[0050] Furthermore, positioning mechanisms 101 are provided at the four corners of the receiving platform 1 , and the positioning mechanisms 101 are used to position the vehicle floor on the vehicle floor assembly device.

[0051] In this embodiment, the positioning mechanism 101 is a bolt, which is moved downward by screwing the bolt, thereby supporting the panel above the home platform 1.

[0052] Furthermore, the control method of the vehicle floor assembly device includes:

[0053] Get the position of the skeleton that needs to be struck;

[0054] The moving device 4 drives the hammer to traverse the long side direction of the skeleton in a stepping manner. After each step, if there is a bone beam in the skeleton below the hammer, the hammer driving device drives the corresponding hammer to knock the mask.

[0055] Furthermore, before the hammer driving device drives the corresponding hammer to strike the mask, the following steps are performed:

[0056] An extension direction angle of the skeleton is obtained, and the hammer is rotated by the hammer rotating device according to the extension direction angle.

[0057] The control method can be specifically implemented through the following steps.

[0058] S1, creating a blank canvas, dividing the canvas into N*M square areas, obtaining an orthographic projection image of the skeleton and filling the blank canvas with it, where N is the number of hammers, and M is the number of steps required for the mobile device to drive the hammer to traverse the long side of the skeleton;

[0059] In this step, the orthographic projection image of the skeleton is as follows Figure 2The result obtained by processing S1 is shown in Figure 3. In this embodiment, the number of hammers is 11, so N=11, the canvas is evenly divided into 11 rows in the vertical direction, the number of steps is 36 times, so M=36, the canvas is evenly divided into 36 splits in the horizontal direction, thus dividing the canvas into 11*36 square areas.

[0060] S2, extracting the area in the square area that overlaps with the orthographic projection image of the skeleton;

[0061] The overlapping area can be extracted through image algorithms, for example, by adjusting the resolution of the skeleton's orthographic projection image to N*M, binarizing the skeleton's orthographic projection image with N*M resolution through binarization, adjusting the binarization threshold, and taking the binarization result with a calculation result of 1 as the overlapping area.

[0062] Alternatively, it can be implemented according to the following description.

[0063] Extracting the area in the square area that overlaps with the orthographic projection image of the skeleton includes: establishing a two-dimensional coordinate system, obtaining integer point coordinates corresponding to each of the square areas, and extracting an overlapping coordinate set of the area in the square area that overlaps with the orthographic projection image of the skeleton, wherein the overlapping coordinate set is an integer point coordinate set;

[0064] like Figure 4 As shown, in this embodiment, the coordinates of the upper right corner of the square area are used as the coordinates of the whole point corresponding to the square area. Figure 4 The lower left area in is used as an example. The overlapping area is as follows Figure 4 The shaded part is shown in . Then, the overlapping coordinate sets are (4, 1), (4, 2), (4, 3), (4, 4), (3, 1), (3, 3), (3, 4), (2, 1), (2, 3), (1, 1), (1, 2), (1, 3), (1, 4).

[0065] The method for determining whether the overlapping area exists below the hammer is as follows:

[0066] The stepping distance of the mobile device is the length of the long side of the skeleton / M. The hammers are numbered from 1 to N along one of the coordinate axes, and the walking distance of the mobile device is numbered from 1 to M along the other coordinate axis. The coordinates (n, m) of all the hammers at different positions are obtained, where n belongs to 1 to N and m belongs to 1 to M.

[0067] After each step of the hammer, if the coordinates (n, m) of the position of the hammer include coordinates belonging to the overlapping coordinate set, it is determined that the overlapping area exists below the hammer.

[0068] In the above, we obtain a set of overlapping coordinates. In this step, we further determine whether there is an overlapping area under the hammer. In this step, we first number the hammers, 1, 2, 3, ... N. Then, when the hammer is in its initial position, that is, the distance it has traveled is 0, then M = 1, and the hammer's coordinates (n, m) are (1, 1), (2, 1), (3, 1), ... (N, 1). When the hammer's distance is one step length, then M = 2, and the hammer's coordinates (n, m) are (1, 2), (2, 2), (3, 2), ... (N, 2), and so on.

[0069] Among them, the larger the M setting is, the greater the gluing effect obtained by the hammer hitting the mask after the method is executed.

[0070] The coordinates of the hammer at each step are now obtained. The presence of an overlapping area below the hammer can be determined by determining whether the coordinates of the hammer at each position match those in the overlapping coordinate set. By dynamically setting the hammer's coordinates, the desired striking position can be determined as the hammer moves.

[0071] S3, gluing the corresponding panels to the frame to form a carriage floor, and positioning the carriage floor on the carriage floor assembly device;

[0072] S4, driving the hammer by the moving device to traverse the long side direction of the skeleton in a stepping manner. After each step, if there is an overlapping area below the hammer, the hammer driving device drives the corresponding hammer to strike the mask.

[0073] In step S2, the position that needs to be struck when the hammer moves can be obtained. In this step, the hammer is controlled to move a certain distance each time in the long side direction of the skeleton. The distance can be the width of the hammer, and then a complete movement is achieved in the length direction of the skeleton. Accurately strike at various positions above the skeleton to ensure that the mask and the skeleton are fully glued together.

[0074] Furthermore, after extracting the area in the square area that overlaps with the orthographic projection image of the skeleton, performing: shape analysis on the overlapping area to obtain contours of the skeleton in the overlapping area, performing line segment fitting on each contour to obtain extension direction angles of the skeleton in the overlapping area;

[0075] Before the hammer driving device drives the corresponding hammer to strike the mask, the following steps are performed: according to the extending direction angle, the hammer is rotated by the hammer rotating device 6 .

[0076] In this embodiment, Hough transform can be used to detect the line segment portion of the contour, and then the angle between the line segment and the X-axis or Y-axis is calculated to serve as the extension direction angle of the skeleton in the overlapping area. The result is as follows: Figure 6 shown.

[0077] Further, according to the extension direction angle, rotating the hammer by the hammer rotating device includes:

[0078] If one or more line segments are obtained after line segment fitting of the contour, and the directions of the line segments are the same, the hammer is rotated by the hammer rotating device so that the bottom end of the hammer is in the same direction as the line segments;

[0079] If more than two line segments are obtained after line segment fitting of the contour, and the directions of the line segments are different, the hammer is rotated by the hammer rotating device so that the bottom end of the hammer is parallel to the long side or short side of the skeleton.

[0080] In this embodiment, since the skeleton is composed of multiple beams, the beams appear as double solid lines after the above-mentioned contour calculation. Therefore, if one or more line segments are obtained after fitting, and several of these line segments are oriented in the same direction, it is determined that a beam passes through the location, and all the beams are oriented in the same direction. In this case, the bottom end of the hammer can be rotated to the same direction as the beam. If two or more line segments are obtained after fitting, and several of these line segments are oriented in different directions, it indicates that multiple beams are present at the location, and the beams may even intersect at the location. In this case, the bottom end of the hammer can be rotated to a fixed direction, such as the front-to-back direction or the left-to-right direction, without any specific adjustment.
