[0045] Embodiment 1

[0046] like Figures 1 to 8As shown, this embodiment provides a quick disassembly and assembly device, which can be installed on a vehicle. The quick disassembly and assembly device is used to fix the vehicle-mounted device 100, and can achieve rapid fixation and contact of the vehicle-mounted device 100, which greatly saves equipment time. At the same time, it has high reliability and ensures the installation stability of the vehicle-mounted device 100 under harsh working conditions.

[0047] Specifically, the quick disassembly and assembly device includes a fixing seat 1 and a fixing mechanism, wherein a plurality of fixing mechanisms are provided, and the plurality of fixing mechanisms are arranged at intervals on the fixing seat 1, and the fixing mechanism can quickly fix and release the vehicle-mounted device 100 placed at a fixed position of the fixing seat 1. The fixing mechanism includes a pressing assembly 2, and the pressing assembly 2 includes a first pressing member 21 and a second pressing member 22, wherein the first end of the second pressing member 22 is rotationally connected to the fixing seat 1, and the second end of the second pressing member 22 is rotationally connected to the connecting end of the first pressing member 21, and when the second pressing member 22 rotates counterclockwise and is located at the initial position, the fixing seat 1 and the second pressing member 22 will also force the first pressing member 21 to rotate clockwise and be located at the initial position, and when the first pressing member 21 and the second pressing member 22 are both located at the initial position, the pressing end of the first pressing member 21 presses the vehicle-mounted device 100. In addition, the fixing mechanism further includes a limiting assembly 3, and the limiting assembly 3 includes a slider 31. The slider 31 is slidably arranged on the side of the second pressing member 22 away from the fixing seat 1. When the second pressing member 22 is located at the initial position, the slider 31 can slide to be partially inserted into the fixing slot 111 of the fixing seat 1, so that the slider 31 is fixed in the fixing slot 111, that is, the second pressing member 22 is fixed on the fixing seat 1. When the second pressing member 22 is located at the initial position, the second pressing member 22 also forces the first pressing member 21 to be located at the initial position. Then, when the second pressing member 22 is fixed at the initial position, the first pressing member 21 is fixed at the initial position, and the vehicle-mounted device 100 located between the pressing end and the fixing seat 1 will not be able to move, thereby achieving the fixation of the vehicle-mounted device 100.

[0048] When the vehicle-mounted device 100 needs to be fixed, the quick disassembly and assembly device provided in this embodiment only needs to drive the slider 31 to move so that the slider 31 is partially inserted into the fixing slot 111, so that the second pressing member 22 and the first pressing member 21 are fixed on the fixing seat 1 at the initial position to clamp and fix the vehicle-mounted device 100. When the vehicle-mounted device 100 needs to be released from the fixing slot 111, the slider 31 only needs to be driven to move so that the slider 31 exits the fixing slot 111, so that the second pressing member 22 and the first pressing member 21 can be released from the fixing, and because the first pressing member 21 and the second pressing member 22 are rotatably connected to the fixing seat 1, the first pressing member 21 and the second pressing member 22 can both leave the initial position to release the clamping of the vehicle-mounted device 100. The quick disassembly and assembly device can ensure that the operator can disassemble and assemble the vehicle-mounted device 100 at any time. The operation is fast and convenient, which can save operation time. At the same time, multiple fixing mechanisms can fix the vehicle-mounted device 100 at the same time, with high reliability, which can ensure the installation stability of the vehicle-mounted device 100 under harsh working conditions.

[0049] In this embodiment, the connecting end of the first pressing member 21 and the second end of the second pressing member 22 are rotatably connected so that the rotation directions of the first pressing member 21 and the second pressing member 22 are opposite. When it is necessary to press the vehicle-mounted device 100, the first pressing member 21 needs to be rotated clockwise to be parallel to the plane where the vehicle-mounted device 100 is located, and the second pressing member 22 needs to be rotated counterclockwise to be parallel to the plane where the vehicle-mounted device 100 is located. When the first pressing member 21 and the second pressing member 22 are both parallel to the plane where the vehicle-mounted device 100 is located, the first pressing member 21 and the second pressing member 22 extend in the extension direction of the second pressing member 22. When there is no need to press the vehicle-mounted device 100, the first pressing member 21 rotates counterclockwise and the second pressing member 22 rotates clockwise, the first pressing member 21 and the second pressing member 22 retract in the extension direction of the second pressing member 22. This can be applied to working conditions where the gap between the vehicle-mounted device 100 and the fixing seat 1 is narrow, and can avoid positional interference between the pressing component 2 and the vehicle-mounted device 100 or the fixing seat 1.

[0050] In this embodiment, Figure 3 and Figure 4As shown, in order to realize that the second pressing member 22 can force the first pressing member 21 to be located at the initial position when it is located at the initial position, a rotation groove 221 is provided at the second end of the second pressing member 22, and the connecting end is inserted into the rotation groove 221 and is rotationally connected to the second pressing member 22. Due to the groove bottom restriction of the rotation groove 221, the first pressing member 21 can rotate toward the side away from the groove bottom, so when the second pressing member 22 is rotated to the initial position, the groove bottom of the rotation groove 221 will press the pressing end of the first pressing member 21 to rotate toward the side away from the second pressing member 22. That is, in this embodiment, if the second pressing member 22 rotates counterclockwise, it will force the first pressing member 21 to rotate clockwise, and when the connecting end of the first pressing member 21 is pressed between the groove bottom of the rotation groove 221 and the fixed seat 1, that is, the first pressing member 21 and the second pressing member 22 are both located at the initial position. When the vehicle-mounted device 100 needs to be released from fixation, the second pressing member 22 can be rotated clockwise to move the second end of the second pressing member 22 away from the fixing seat 1, thereby driving the first pressing member 21 to rotate counterclockwise with the connection end as the center. Since the first pressing member 21 and the second pressing member 22 of the pressing assembly 2 provided in this embodiment are rotatably connected, when the vehicle-mounted device 100 is released from fixation, the first pressing member 21 can be retracted in the extension direction of the second pressing member 22.

[0051] Alternatively, if Figure 7 and Figure 8 As shown, a rotating protrusion 211 is provided at the connecting end of the first pressing member 21, and the rotating protrusion 211 is inserted into the rotating groove 221 of the second pressing member 22. A through hole is provided on the rotating protrusion 211, and the rotating shaft can pass through the through hole on the rotating protrusion 211 and be connected to the second end of the second pressing member 22.

[0052] Furthermore, a limiting protrusion is provided on one of the second pressing member 22 and the slider 31, and a limiting groove 223 is provided on the other, the limiting protrusion is slidably inserted in the limiting groove 223, and the limiting groove 223 extends along the sliding direction of the slider 31. The setting of the limiting protrusion and the limiting groove 223 can ensure that the slider 31 always slides on the second pressing member 22 to prevent the slider 31 from being separated from the second pressing member 22, and on the other hand, ensure that each sliding path of the slider 31 is consistent, so that the slider 31 can be accurately and quickly inserted into the fixed slot 111 each time.

[0053] Alternatively, if Figure 4As shown, a slide groove 222 is further provided on the second pressing member 22, and the slider 31 is slidably provided in the slide groove 222. The slide groove 222 is provided to limit the sliding direction of the slider 31 on the second pressing member 22, and the aforementioned limiting protrusion and limiting groove 223 are provided to further prevent the slider 31 from being separated from the slide groove 222 in the groove depth direction of the slide groove 222. In this embodiment, the limiting protrusion is provided on the slider 31, and the limiting groove 223 is provided on the inner wall of the slide groove 222. Both ends of the second pressing member 22 in the extending direction of the slide groove 222 are penetrated, and one end is penetrated so that the slider 31 can be moved into the fixed slot 111, and the other end is penetrated so that the slider 31 can be installed in the slide groove 222.

[0054] In this embodiment, the second pressing member 22 includes two second pressing plates respectively arranged on both sides of the slide slot 222, and the first pressing member 21 also correspondingly includes two first pressing plates, and one first pressing plate is rotatably connected to one second pressing plate.

[0055] Alternatively, if Figure 2 As shown, a fixed stopper 11 is also provided on the fixed seat 1, and the fixed stopper 11 and the fixed seat 1 are surrounded to form a fixed slot 111. In this embodiment, the fixed stopper 11 is a fixed rod, and both ends of the fixed rod are connected to the fixed seat 1 to form the fixed slot 111 with the fixed seat 1, and the slider 31 is inserted into the fixed slot 111 when it moves between the fixed rod and the fixed seat 1.

[0056] In other embodiments, a fixed stopper 11 may be provided on the fixing seat 1 , and the fixed slot 111 may be provided only on the fixed stopper 11 . Then, the slider 31 is moved into the fixed stopper 11 and inserted into the fixed slot 111 .

[0057] Furthermore, if Figure 5 As shown, the limiting assembly 3 also includes a lever 32 and a connecting rod 33. One end of the lever 32 is rotatably connected to the fixed seat 1 through a first rotating shaft 34, and the middle section of the lever 32 is rotatably connected to the connecting rod 33 through a second rotating shaft 35. The end of the connecting rod 33 that is not connected to the lever 32 is rotatably connected to the slider 31 through a third rotating shaft 36. The operator can rotate the other end of the lever 32 to drive the slider 31 to move on the second pressing member 22 through the connecting rod 33, and the first end of the second pressing member 22 is also rotatably connected to the fixed seat 1 through the first rotating shaft 34.

[0058] Optionally, the central axis of the first rotating shaft 34, the central axis of the second rotating shaft 35 and the central axis of the third rotating shaft 36 are coplanar. When the lever 32 rotates to drive the slider 31 to be inserted into the fixed slot 111, even if the vehicle is in a relatively bumpy environment and the slider 31 can only slide along the extension direction of the connecting rod 33, the moving direction of the slider 31 is consistent with the direction of the force transmitted by the slider 31 to the connecting rod 33. At this time, the slider 31 and the connecting rod 33 will be in a dead top position, that is, without moving the lever 32, the slider 31 cannot push the connecting rod 33 to rotate to slide out of the fixed slot 111.

[0059] Alternatively, if Figures 4 to 6 As shown, the quick disassembly and assembly device also includes a sealing component 4, which includes a sealing rubber plate 41. The sealing rubber plate 41 is arranged on the fixing surface of the fixing seat 1. When the vehicle-mounted equipment 100 is placed on the fixing surface, the vehicle-mounted equipment 100 abuts against the sealing rubber plate 41, and the fixing mechanism applies pressure to the vehicle-mounted equipment 100, so that the vehicle-mounted equipment 100 and the sealing rubber plate 41 can be tightly abutted, thereby achieving a sealed contact between the vehicle-mounted equipment 100 and the sealing rubber plate 41, so that the vehicle-mounted equipment 100 is fixed more firmly.

[0060] Optionally, the sealing assembly 4 also includes a fixed pressure ring 42, which is used to clamp the outer edge of the sealing rubber plate 41 between the fixed pressure ring 42 and the fixed seat 1. In this embodiment, the sealing rubber plate 41 is an annular structure, and the fixed pressure ring 42 includes an inner ring and an outer ring, and the inner ring is arranged at the inner edge of the sealing rubber plate 41 and fixed on the fixed seat 1, while the outer ring is arranged at the outer edge of the sealing rubber plate 41 and fixed on the fixed seat 1. The fixed seat 1 is also provided with an inner pressure groove and an outer pressure groove, so that the inner ring can be fixed in the inner pressure groove, and the outer ring is fixed in the outer pressure groove, and does not protrude from the surface of the sealing rubber plate 41 where the fixed pressure ring 42 is not provided, so as to ensure that the vehicle-mounted equipment 100 is only in contact with the sealing rubber plate 41, but not with the fixed pressure ring 42. In this embodiment, the fixed pressure ring 42 is a metal part, which can ensure that the connection between the fixed pressure ring 42 and the fixed seat 1 is stable for fixing the sealing rubber plate 41.

[0061] Embodiment 2

[0062] like Fig. 9 and Fig.10 As shown, this embodiment provides a quick disassembly and assembly device. The difference between the quick disassembly and assembly device provided in this embodiment and the quick disassembly and assembly device in the first embodiment is that:

[0063] The first end of the second pressing member 22 is rotatably connected to the fixing seat 1 via the fourth rotating shaft 37. That is, the second pressing member 22 and the lever 32 may have different rotation centers from the fixing seat 1, and the two may be separately arranged without increasing the thickness of the second pressing member 22, and the assembly flexibility between the structures is higher.

[0064] In addition, the quick disassembly and assembly device provided in this embodiment is consistent with the quick disassembly and assembly device in the first embodiment, and will not be described in detail here.
