Description

Technical Field

[0001] This utility model applies to the field of special vehicle technology, and particularly relates to a concealed side cabinet for a special vehicle compartment. Background Technology

[0002] Currently, special vehicles refer to vehicles whose external dimensions, weight, etc. exceed the design vehicle limits and vehicles for special purposes, or motor vehicles that have been specially made or modified and equipped with fixed devices and equipment, whose main function is not to carry people or goods.

[0003] However, nowadays, special vehicles often contain a large number of specialized tools. To facilitate the categorization and storage of these tools, they are typically placed in cabinets within the vehicle's cargo compartment in a specific order. To minimize the space occupied by these cabinets, they are often embedded into the compartment walls. When tools need to be retrieved, the operator must pull the cabinet outwards to remove it from the compartment wall. Given the considerable weight of the cabinets filled with tools, this requires excessive effort and is time-consuming, hindering the speed of tool retrieval and use. Therefore, we propose a concealed side cabinet for special vehicle cargo compartments. Utility Model Content

[0004] The main purpose of this utility model is to provide a hidden side cabinet for the carriage of special vehicles, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A concealed side cabinet for a special vehicle compartment includes a compartment frame. A storage frame is fixedly installed on the side of the compartment frame. A support ramp is fixedly installed on the bottom inner side of the storage frame. A cabinet is slidably installed between the tops of two sets of support ramps. A cabinet door is hinged to the side of the cabinet via a pivot. Connecting plates are fixedly installed on both sides of the bottom of the cabinet, and the connecting plates slide against the outside of the transmission frame. A limit bolt is threaded through the middle of the side of each connecting plate, and the side of the limit bolt is against the outside of the transmission frame.

[0007] The storage box has a transmission frame fixedly installed at both ends of the bottom inside. Each transmission frame has a sliding frame hinged to the top of it via a pivot. Each sliding frame has a sliding mechanism inside it, and the sliding mechanism is connected to the bottom of the cabinet via a transmission.

[0008] Each of the aforementioned transmission frames is equipped with a pushing mechanism, and the pushing mechanism is connected to the bottom of the sliding frame via a transmission connection;

[0009] The sliding frame is equipped with a damping buffer mechanism on the side away from the cabinet door.

[0010] By adopting the above technical solution, the sliding frame can be tilted by rotating at the top of the transmission frame due to the pushing action of the pushing mechanism and the sliding transmission action of the sliding mechanism on the cabinet. This allows the cabinet placed on its surface to slide out of the storage frame synchronously under its own weight, reducing the labor consumption and operation steps required for the operator to manually pull and move the cabinet, and facilitating the retrieval and use of special tools inside the cabinet.

[0011] As an optional solution to the technical solution of this application, the pushing mechanism includes a rotating lead screw and a pushing rod. A rotating lead screw is rotatably installed inside each transmission frame via a bearing. A transmission sleeve is movably sleeved on the outer surface of each rotating lead screw via a thread. A servo motor is fixedly installed on the outer side of each transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the top side of the rotating lead screw via a coupling. A connecting frame is installed on the top side of the outer side of each transmission sleeve and the bottom side of the sliding frame. A pushing rod is hinged between the sides of every two sets of connecting frames via a rotating shaft. A movable groove is opened at the middle of the top of each transmission frame, and the pushing rod slides through and is inserted into the movable groove.

[0012] By adopting the above technical solution, the horizontal movement force of the transmission sleeve can be converted into a vertical pushing and pulling force on the sliding frame through the rotational transmission action of the rotating lead screw and the transmission conversion action of the push rod.

[0013] As an optional solution to the technical solution of this application, the sliding mechanism includes a pressing block and a sliding block. A pressing block is slidably installed inside each sliding frame on the side near the cabinet. A sliding block is fixedly installed on the top surface of each pressing block, and the top of the sliding block is fixedly connected to the bottom of the cabinet. A sliding groove is opened inside the top of each sliding frame, and the sliding block is slidably inserted into the sliding groove.

[0014] By adopting the above technical solution, the sliding block is guided and slid by the sliding groove, and the sliding block is connected and transmitted, so that the cabinet can drive the pressing block to move synchronously inside the sliding frame when it moves.

[0015] As an optional solution to the technical solution of this application, the damping buffer mechanism includes a buffer spring and a damping slider. A damping slider is slidably installed on the inner side of each sliding frame away from the cabinet, and a buffer spring is movably installed on the inner side of each sliding frame away from the cabinet, with the side of the buffer spring movably attached to the outer side of the damping slider.

[0016] By adopting the above technical solution, the movement speed of the cabinet is slowed down and protected by the structure of the buffer spring, so as to avoid the movement speed being too fast and affecting its use.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The concealed side cabinet of the special vehicle compartment in this application connects the cabinet body and the pressing block located in the sliding frame via a sliding block. This allows the pressing block and the sliding block to slide inside and outside the sliding frame, simultaneously moving the cabinet body horizontally within the storage frame. Combined with the rotational transmission action of the rotating screw on the transmission sleeve, the rotating screw can drive the transmission sleeve to move horizontally within the transmission frame. Furthermore, the rotational hinge of the rotating shaft allows the two ends of the push rod to rotate synchronously with the transmission sleeve and the connection point on the outside of the sliding frame, thereby converting the horizontal movement force of the transmission sleeve into a vertical pushing and pulling force on the sliding frame. This allows the sliding frame to rotate at the top of the transmission frame and tilt, enabling the cabinet placed on its surface to slide out of the storage frame under its own weight. This reduces the labor and operational steps required for manual pulling and moving of the cabinet, and facilitates the retrieval and use of special tools inside the cabinet.

[0019] 2. The concealed side cabinet of the special vehicle compartment in this application has a buffer spring and a damping slider installed on the front side inside the sliding frame. When the cabinet moves forward and slides out of the storage frame, the pressing block moves synchronously and contacts the damping slider, causing it to move synchronously inside the sliding frame. When it contacts the buffer spring and causes it to deform, the moving speed of the sliding block and the cabinet can be slowed down, avoiding the cabinet from moving out too fast and colliding with the front end of the sliding frame, thereby improving the protection of the storage and placement of special tools inside the cabinet.

[0024] like Figure 1-3 As shown, this utility model provides a technical solution: a hidden side cabinet for a special vehicle compartment. A storage frame 11 is fixedly installed on the side of the compartment frame 1. A support inclined block 16 is fixedly installed on the bottom inner side of the storage frame 11. A cabinet body 12 is slidably installed between the tops of the two sets of support inclined blocks 16. A cabinet door 13 is hinged to the side of the cabinet body 12 via a pivot. Connecting plates 14 are fixedly installed on both sides of the bottom of the cabinet body 12. The connecting plates 14 are slidably attached to the outside of the transmission frame 2. A limit bolt 15 is threaded through and screwed to the middle of the side of each connecting plate 14. The side of the limit bolt 15 is attached to the outside of the transmission frame 2.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each transmission frame 2 is equipped with a pushing mechanism inside, and the pushing mechanism is connected to the bottom of the sliding frame 21. The pushing mechanism includes a rotating screw 22 and a pushing rod 25. Each transmission frame 2 has a rotating screw 22 rotatably mounted inside via a bearing. Each rotating screw 22 has a transmission sleeve 23 threadedly fitted onto its outer surface. Each transmission frame 2 has a servo motor 26 fixedly mounted on its outer side. The side of the transmission shaft of the servo motor 26 is fixedly connected to the top of the side of the rotating screw 22 via a coupling. Each transmission sleeve 23 has a connecting frame 24 mounted on its outer top and the bottom side of the sliding frame 21. A pushing rod 25 is hinged between the sides of every two sets of connecting frames 24 via a rotating shaft. Each transmission frame 2 has a movable groove 41 at its top center, and the pushing rod 25 slides through and is inserted into the movable groove 41.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown), transmission frames 2 are fixedly installed at both ends of the bottom inner side of the storage frame 11. Each transmission frame 2 has a sliding frame 21 hinged to its top via a pivot. Each sliding frame 21 has a sliding mechanism inside, and the sliding mechanism is connected to the bottom of the cabinet 12 via a transmission. The sliding mechanism includes a pressing block 27 and a sliding block 28. A pressing block 27 is slidably installed on the side of each sliding frame 21 near the cabinet 12. A sliding block 28 is fixedly installed on the top surface of each pressing block 27, and the top of the sliding block 28 is fixedly connected to the bottom of the cabinet 12. A sliding groove 4 is opened inside the top of each sliding frame 21, and the sliding block 28 is slidably inserted into the sliding groove 4.

[0027] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, each sliding frame 21 has a damping buffer mechanism installed on the side away from the cabinet door 13. The damping buffer mechanism includes a buffer spring 3 and a damping slider 31. A damping slider 31 is slidably installed on the inner side of each sliding frame 21 away from the cabinet body 12. A corresponding damping pad is sleeved on the outer side of the damping slider 31. The outer side of the damping slider 31 contacts the inner wall of the sliding frame 21 to generate frictional damping, thereby damping the elastic recovery of the buffer spring 3 and preventing the recovery speed from being too fast and affecting the normal use of the cabinet body 12. A buffer spring 3 is movably installed on the inner side of each sliding frame 21 away from the cabinet body 12, and the side of the buffer spring 3 is movably attached to the outer side of the damping slider 31.

[0028] During operation, when it is necessary to remove the cabinet 12 from the storage box 11 to retrieve and use the special tools inside, the limit bolt 15 is turned in the opposite direction to move its side away from the outer wall of the transmission frame 2. Simultaneously, the servo motor 26 is turned on by the external control switch, causing it to rotate and drive the rotating screw 22 to rotate synchronously inside the transmission frame 2. Combined with the guiding and limiting effect of the movable groove 41 on the push rod 25, the transmission sleeve 23 on the surface of the rotating screw 22 can be driven to move horizontally to the right synchronously inside the transmission frame 2. Subsequently, under the transmission conversion effect of the push rod 25, the horizontal moving force of the transmission sleeve 23 can be converted into a vertical pushing and pulling force on the sliding frame 21, so that the sliding frame 21 can rotate counterclockwise at the top of the transmission frame 2 and tilt, allowing the cabinet 12 placed on its surface to slide synchronously under its own weight. Subsequently, under the guiding and sliding effect of the sliding groove 4 on the sliding block 28, The pressing block 27 moves to the left inside the sliding frame 21 until it contacts the damping slider 31 and presses it, causing it to move to the left inside the sliding frame 21. This presses the buffer spring 3 and causes it to deform, thus slowing down the sliding speed of the cabinet 12. The cabinet door 13 is then rotated and opened to retrieve the special tools inside the cabinet 12. When storing the cabinet 12, the servo motor 26 is turned on by the external control switch, causing the rotating screw 22 to rotate in the opposite direction. The above operation steps are repeated, causing the sliding frame 21 to return to its original position. The sliding frame 21 then slides and moves to be stored inside the storage frame 11. The limit bolt 15 is then tightened to make its side fit tightly against the outside of the transmission frame 2, thus fixing the cabinet 12. The storage of the cabinet 12 is then completed.
