Description

Technical Field

[0001] The utility model relates to a chassis. Background Art

[0002] Existing chassis are generally tightly connected by multiple screws or bolts. Therefore, when performing maintenance, users need to remove multiple screws or bolts on the chassis before they can repair the components inside the chassis, which undoubtedly increases the difficulty of chassis maintenance. Summary of the Utility Model

[0003] The main object of the utility model is to provide a chassis, aiming to solve the above technical problems.

[0004] To achieve the above object, a chassis proposed by the utility model includes a housing having a receiving cavity and control components all received in the receiving cavity. The housing includes a top cover, a bottom cover and a surrounding plate. The top cover and the bottom cover are oppositely arranged and are respectively arranged at the top and bottom of the surrounding plate to enclose the receiving cavity. The surrounding plate includes four side plates connected end to end in sequence. Adjacent two side plates are connected by a locking structure so that the side plates are limited to move only in the height direction.

[0005] In one embodiment, the locking structure includes a first locking member and a second locking member. The first locking member and the second locking member are respectively arranged on adjacent two side plates, and the ends of the first locking member and the second locking member close to each other are locked and connected.

[0006] In one embodiment, the first locking member is slidably arranged on the side plate, and the second locking member is fixedly arranged on the adjacent side plate.

[0023] Moreover, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0024] The present utility model provides a chassis.

[0025] As Figure 1 shown, the chassis provided by the embodiment of the present utility model includes a housing 10 having a receiving cavity and a control component 20 both received in the receiving cavity. The housing 10 includes a top cover 11, a bottom cover 12, and a surrounding plate 13. The top cover 11 and the bottom cover 12 are oppositely arranged and are respectively provided at the top and bottom of the surrounding plate 13 to enclose the receiving cavity. The surrounding plate 13 includes four side plates 14 connected end to end in sequence. Adjacent two of the side plates 14 are connected by a locking structure 30 so that the side plates 14 are limited to move only in the height direction.

[0026] In this embodiment, adjacent two side plates 14 can be connected by the locking structure 30, so that the side plates 14 can only move in the height direction, so as to minimize the difficulty of maintenance caused by bolt fixing and achieve the purpose of fixing the chassis at the same time.

[0027] It is understandable that, in order to improve the stability of the chassis, additional bolts can be added for fastening connection. However, compared with the existing technology that completely uses bolts for connection, the present application obviously has the beneficial effect of being convenient for disassembly and assembly.

[0028] In the present application, the chassis provided by the present application is applicable to the control of unmanned aerial vehicles. Therefore, in order to avoid electromagnetic interference to the chassis, it is generally required that the holes on the chassis are not larger than λ / 20 (λ is the wavelength), and in a microwave environment, it is required that the holes are not larger than λ / 50.

[0029] Please refer to Figure 2 , the locking structure 30 includes a first locking member 31 and a second locking member 32. The first locking member 31 and the second locking member 32 are respectively arranged on two adjacent side plates 14, and the ends of the first locking member 31 and the second locking member 32 close to each other are locked and connected. In this embodiment, both the first locking member 31 and the second locking member 32 include an extension portion 311 and a hook portion 312, and the two hook portions 312 are mutually engaged to limit the sliding of the locking structure 30 on the plane where it is located.

[0030] Therefore, through the locking cooperation of the first locking member 31 and the second locking member 32, it is possible to prevent the locking structure 30 from sliding on the plane where it is located, so that it can only be disassembled and assembled by sliding in the height direction. In an optional embodiment, a lockable second fastener can be added at the connection of the first locking member 31 and the second locking member 32 to tightly fit the first locking member 31 and the second locking member 32, so as to achieve the purpose of limiting the position in the height direction. It is understandable that the hook portion 312 is inclined at an angle of 15° to 45° toward the extension portion 311. Within this angle range, the cooperation effect of the first locking member 31 and the second locking member 32 is the best, neither easily slipping off the connection nor improving the relatively stable biting force.

[0031] In an optional embodiment, the first locking member 31 is slidably arranged on the side plate 14, and the second locking member 32 is fixedly arranged on the adjacent side plate 14. In other words, the first locking member 31 can adjust the cooperation position by sliding to avoid the control component 20. Similarly, the second locking member 32 can also be arranged in a sliding manner, so that the first locking member 31 and the second locking member 32 can slide on the side wall for adjustment.

[0032] Specifically, a slide rail is provided on the inner wall surface of the side plate 14, and a lockable connecting member 33 is slidably arranged on the slide rail. Both the first locking member 31 and the second locking member 32 are connected to the connecting member 33. In this embodiment, a lockable first fastener can be provided between the connecting member 33 and the slide rail. Thus, after the first locking member 31 and the second locking member 32 are adjusted to the proper mating positions, the position can be fixed by tightening the first locking member 31, improving stability.

[0033] Among them, the connecting member 33 includes a bottom plate slidably arranged on the slide rail and connecting plates arranged at both ends of the bottom plate. The two connecting plates and the bottom plate enclose a U-shaped clamping cavity 34. The ends of the first locking member 31 and the second locking member 32 are clamped in the U-shaped clamping cavity 34. In this embodiment, the ends of the first locking member 31 and the second locking member 32 extend into the U-shaped clamping cavity 34. Generally, an interference fit can be adopted for connection. Of course, in other embodiments, a third fastener with a locking function can also be added for cooperation.

[0034] Based on the above embodiments, even if several fasteners with locking functions are used to cooperate at the joints of the components in this application, compared with the prior art where bolts are completely used for connection, this application obviously has the beneficial effect of being convenient for disassembly and assembly.

[0035] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the concept of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
