Referring to fig. 1 again, the housing assembly 2 includes a housing 21, and a circuit board 22 is disposed inside the housing 21. In an embodiment, the circuit board 22 inside the box 21 may be electrically connected to the display 1 through a cable, so as to implement data transmission between the display 1 and the circuit board 22. As shown in fig. 1, the box 21 is substantially rectangular, and has a first top plate 211, a first bottom plate 212 and a side plate 213 connected between the first top plate 211 and the first bottom plate 212, the first top plate 211 is fixed with the fixing seat 41 of the lifting bracket 4, and the first bottom plate 212 is supported on the base 3. In other words, the display 1, the lifting stand 4, the case assembly 2 and the base 3 of the medical apparatus 100 are arranged substantially along the vertical direction Y, and the relative positions of the components are such that the medical apparatus 100 has a certain height, so that the display 1 has a height which is convenient for a user to view, and the structure of the medical apparatus 100 is optimized.

Further, referring to fig. 2, the housing assembly 2 further includes a frame 25 fixedly connected to the inside of the box 21, the frame 25 includes a top portion 251 and a bottom portion 252, the top portion 251 and the bottom portion 252 are disposed opposite to each other along a gravity direction of the functional module 23, i.e., a vertical direction Y, and at least one of the top portion 251 or the bottom portion 252 has a gap with the functional module 23. Specifically, when the functional module 23 is in the non-shaking state, the functional module 23 may be carried on the bottom 252 of the frame 25, and an end surface of the functional module 23 facing the top 251 is spaced from the top 251 by a gap. The clearance between the functional module 23 and the top 251 facilitates the assembly of the functional module 23 to the case 21. In other words, the gap between the functional module 23 and the top 251 forms the movable space 214 of the functional module 23 in the box 21.
Compared with the technical scheme that the board card 24 and the circuit board 22 are plugged through the electric connector, the reliability of the chassis assembly is improved according to the embodiment of the application. For example, a male socket of an electrical connector is soldered to the circuit board 22, and a female socket of an electrical connector is soldered to the board 24. When the electrical connection between the board card 24 and the circuit board 22 is realized, the female socket can be aligned with the male socket by adjusting the position of the board card 24, so that the board card 24 is plugged with the circuit board 22. Wherein, the position of its public seat on the relative circuit board 22 of clearance adjustment is needed to integrated circuit board 24, just can guarantee that the female seat of integrated circuit board 24 can peg graft on the public seat on circuit board 22, therefore, functional module 23 that is provided with integrated circuit board 24 has the space that can move about in box 21, and this functional module 23 makes chassis component 2 when receiving external force in the activity space 214 in box 21, functional module 23 can vibrate in this activity space 214, if functional module 23 and 24 fixed connection of integrated circuit board, then can drive integrated circuit board 24 and vibrate together, integrated circuit board 24 drives circuit board 22 vibration then, thereby damage circuit board 22.
Referring to fig. 3, the chassis assembly 2 of the embodiment of the present disclosure further includes a connector 26, the board 24 is limited to be connected to the functional module 23 through the connector 26, and the functional module 23 can move relative to the board 24. The connection restriction is understood to mean that the board 24 can move relative to the functional module 23 without leaving the board 24. The board card 24 is limited to be connected to the functional module 23 through the connecting piece 26, and the board card 24 can move relative to the functional module 23, so that when the functional module 23 is shaken by external force, the functional module 23 moves relative to the board card 24, force generated by vibration of the functional module 23 can not be transmitted to the circuit board 22 electrically connected with the board card 24 through the board card 24, damage to the circuit board 22 is avoided, and reliability of the case assembly 2 and the medical equipment 100 is improved. Further, as shown in fig. 2, the clearance between at least one of the top portion 251 or the bottom portion 252 and the functional module 23 is smaller than the distance that the functional module 23 moves in the direction of gravity relative to the board 24. Specifically, the clearance between the top 251 and the functional module 23 is smaller than the distance that the functional module 23 moves in the gravity direction relative to the board 24. In other words, even if the functional module 23 is pushed to the top 251 or pushed to the bottom 252 in the vibration process, the self-vibration force of the functional module 23 cannot be transmitted to the board card 24, so that the board card 24 is prevented from being driven by the functional module 23 to vibrate together, the circuit board 22 is prevented from being damaged, and the reliability of the chassis assembly 2 is further improved.
In one embodiment, the frame 25 further includes a side portion including a first side portion and a second side portion, the first side portion and the second side portion are oppositely disposed around the function module 23 along a horizontal direction of the function module 23, and at least one of the first side portion and the second side portion has a gap with the function module 23, the gap being smaller than a distance that the function module 23 moves in the horizontal direction with respect to the board 24.
It can be understood that, in the case assembly 2 shown in fig. 3, there are 2 connecting members 26, each of which is disposed near one side of the board 24, so as to realize a stable connection between the board 24 and the functional module 23. Of course, in other embodiments, the number of connectors 26 may be 1, 3, etc.
In one embodiment, as shown in fig. 4, the functional module 23 is moved relative to the board 24 in the plane of the board 24 and/or in the thickness direction of the board 24. In other words, the functional module 23 can move relative to the connector 26 without departing from the board 24, and the movement of the functional module 23 relative to the connector 26 includes: the movement of the functional module 23 relative to the connector 26 in the plane of the card 24 and the movement of the functional module 23 in the thickness direction of the card 24, i.e. in the axial direction of the connector 26. When the functional module 23 vibrates in the movable space 214, the functional module 23 moves relative to the board 24 along the plane where the board 24 of the connecting member 26 is located, so that the board 24 is prevented from being driven to vibrate by the vibration of the functional module 23, the circuit board 22 is prevented from being damaged, and the reliability of the case assembly 2 and the medical device 100 is improved. The board card 24 and the functional module 23 have degrees of freedom in the plane of the board card 24 and in the thickness direction of the board card 24, the degrees of freedom are limited within a certain range according to different requirements of application scenes, good electrical signal transmission of the board card 24 and the circuit board 22 is guaranteed, and accordingly reliability of the medical device 100 is improved. Of course, in other embodiments, the functional module 23 moves relative to the board 24 in the plane of the board 24, or the functional module 23 moves relative to the board 24 in the thickness direction of the board 24.
Optionally, one end of the connecting element 26 is fixedly connected to one of the functional module 23 or the board 24, and the other end of the connecting element 26 is in clearance fit with the other of the functional module 23 or the board 24 along the circumferential direction P of the connecting element 26. Wherein the circumferential direction P can be understood as the direction around the central axis of the connection. In one embodiment, referring to fig. 4, one end of the connecting member 26 is fixedly connected to the functional module 23, and the other end of the connecting member 26 is in clearance fit with the board 24 along the circumferential direction P of the connecting member 26. When the functional module 23 vibrates in the movable space 214, since the other end of the connecting member 26 and the board card 24 have a gap along the circumferential direction P of the connecting member 26, the functional module 23 can drive the connecting member 26 to move between the other end of the connecting member 26 and the gap of the board card 24, in other words, the force of the vibration of the functional module 23 cannot be transmitted to the board card 24, the vibration of the functional module 23 is prevented from driving the board card 24 to vibrate, the circuit board 22 is prevented from being damaged, and the reliability of the chassis assembly 2 and the medical device 100 is improved. The other end of the connecting piece 26 is in clearance fit with the board card 24 to realize the relative movement of the functional module 23 and the board card 24, so that the collision frequency of the other ends of the board card 24 and the connecting piece 26 in the relative movement process is reduced, the damage to the board card 24 and the connecting piece 26 is avoided, and the reliability of the case assembly 2 is further improved. Of course, in other embodiments, as shown in fig. 5, one end of the connecting member 26 is fixedly connected to the board 24, and the other end of the connecting member 26 is in clearance fit with the functional module 23 along the circumferential direction P of the connecting member 26. When the functional module 23 vibrates in the movable space 214, since the other end of the connecting member 26 and the functional module 23 have a gap along the circumferential direction P of the connecting member 26, the functional module 23 can move in the gap between itself and the other end of the connecting member 26, in other words, the force of the vibration of the functional module 23 can not be transmitted to the other end of the connecting member 26 basically, and further can not be transmitted to the board card 24 basically, the vibration of the functional module 23 is prevented from driving the board card 24 to vibrate, the circuit board 22 is prevented from being damaged, and the reliability of the chassis assembly 2 and the medical device 100 is improved. Optionally, the functional module 23 has a second hole 23a, a convex portion forming connection 26 is convexly disposed on a side of the board 24 facing the functional module 23, the convex portion extends toward a direction close to the functional module 23 until being inserted into the second hole 23a of the functional module 23, and the convex portion and the second hole 23a of the functional module 23 are spaced apart from each other along a circumferential direction P of the convex portion. Specifically, the card 24 and the connector 26 may be integrally formed. The connector 26 may be a post formed from the card 24 as it is being manufactured. The connector 26 may also be a metal post soldered to the card 24. The end of the connecting member 26 protrudes into the second hole 23a of the functional module 23, and when the functional module 23 vibrates in the movement space 214, the functional module 23 moves in the gap between itself and the end of the connecting member 26 in the circumferential direction P.
The structure of the connecting member 26 includes, but is not limited to, the following embodiments:
in an alternative embodiment, as shown in fig. 4, the board 24 is provided with a first hole 24a, the connecting member 26 includes a threaded portion 261 and a connecting portion 262, which are sequentially connected, the threaded portion 261 passes through the first hole 24a of the board 24 and is screwed onto the functional module 23, the connecting portion 262 is limited to be connected onto the board 24, at least a portion of the connecting portion 262 is located in the first hole 24a of the board 24, and at least a portion of the connecting portion 262 is spaced from a hole wall of the first hole 24a of the board 24 along the circumferential direction P. In particular, the number of first holes 24a matches the number of connectors 26. The first hole 24a is a circular hole. When the functional module 23 is not vibrated, the connecting portion 262 of the connecting member 26 may abut against the hole wall of the board 24. When the functional module 23 vibrates in the movable space 214, the functional module 23 drives the connecting portion 262 of the connecting member 26 to move between the gap between the connecting portion 262 and the first hole 24a of the board 24, so as to prevent the board 24 from being vibrated by the vibration of the functional module 23, thereby preventing the circuit board 22 from being damaged and improving the reliability of the chassis assembly 2 and the medical device 100.
It will be appreciated that, as shown in fig. 4 and 6, the connecting portion 262 has a smooth section 262a and a limiting section 262b, the smooth section 262a is located in the first hole 24a of the card 24, and the limiting section 262b abuts against the card 24 to limit the axial movement of the card 24 relative to the connecting member 26 along the first hole 24 a. Through setting up smooth section 262a with connecting portion 262, and smooth section 262a is located the first hole 24a of integrated circuit board 24 for smooth section 262a is when functional module 23 does not vibrate and the butt on the pore wall of integrated circuit board 24, and stress is less each other when the pore wall of integrated circuit board 24 contacts with smooth section 262a, improves the life of the two, has further improved quick-witted case subassembly 2's reliability.
It should be noted that the smooth section 262 is a smooth cylindrical surface.

Specifically, the diameter of the outer peripheral surface of the limiting section 262b is larger than the aperture of the first hole 24a, and the end surface of the limiting section 262b facing the board card 24 can abut against the board card 24. When screw thread portion 261 threaded connection is on function module 23, spacing section 262b butt is on integrated circuit board 24 to prevent that integrated circuit board 24 from droing from connecting piece 26, smooth section 262a and the clearance fit in first hole 24a simultaneously, make function module 23 can drive smooth section 262a and remove in integrated circuit board place plane, make the power that function module 23 vibration produced can not transmit to integrated circuit board 24 on. The structure that the terminal surface butt integrated circuit board 24 of the spacing portion of this connecting piece 26's terminal surface realized that integrated circuit board 24 and connecting portion 262's restriction are connected, when facing the integrated circuit board 24 of different thickness, only need adjust the length of the threaded connection of screw portion 261 and functional module 23 of connecting piece 26 to make the terminal surface of spacing portion can butt integrated circuit board 24's terminal surface, and the suitability is strong, and is hard in dismantling.
In one embodiment, the height of the smooth section 262a along the thickness of the card 24 is greater than the thickness of the card 24. Thus, after the threaded portion 261 is connected to the functional module 23, the spacing portion 262b has a distance from the surface of the board card 24, so that the connecting piece 26 can move in the thickness direction of the board card 24 relative to the board card 24, and the functional module 23 can move in the thickness direction of the board card 24 relative to the board card 24.
In one embodiment, at least a portion of the connecting portion 262 is spaced from the hole wall of the first hole 24a of the card 24 along the circumferential direction P, and the height of the smooth portion 262a along the thickness direction of the card 24 is greater than the thickness of the card 24. So for functional module 23 can remove in the plane of integrated circuit board 24 and integrated circuit board 24's thickness direction relative integrated circuit board 24 to realize that integrated circuit board 24 all has the degree of freedom to each angular vibration of functional module 23, increased the stability of quick-witted case subassembly when facing complicated vibration.
In one embodiment, the diameter of the position-limiting section 262b is larger than that of the smooth section 262a, and the diameter of the smooth section 262a is larger than that of the threaded section 261, in other words, the connecting member 262 has a stepped structure.
In another alternative embodiment, as shown in fig. 7, the limiting section 262b is protruded on the outer peripheral surface of the smooth section 262a, the hole wall of the first hole 24a of the board 24 is concavely provided with a concave portion 23b, and the limiting section 262b is inserted into the concave portion 23 b. Specifically, the depth of the concave portion 23b is greater than the length of the limiting section 262b, and the limiting section 262b is inserted into the concave portion 23b and can move in the concave portion 23b, so that the board card 24 is prevented from falling off from the connecting member 26. Of course, in other embodiments, the limiting section 262b can be disposed around the smooth section 262 a.
It is understood that the material of the connecting member 26 may be metal, may be made of an elastic material, etc.
When the functional module 23 in the case assembly 2 provided by the embodiment of the present application is vibrated, the functional module 23 moves relative to the board card 24: for example, as shown in fig. 4, the functional module 23 moves in the first hole 24a of the board 24 in the plane of the board by driving the smooth portion of the connecting member 26; as another example, as shown in fig. 5, the functional module 23 moves in a gap between itself and the circumferential direction P of the end of the connecting member 26; in other words, the vibration force of the functional module 23 is not transmitted to the board 24, so that the board 24 is prevented from being driven by the functional module 23 to vibrate together, and the circuit board 22 is prevented from being damaged.
The case subassembly 2 that this application embodiment provided and medical equipment 100's integrated circuit board 24 is restricted to be connected on function module 23 through connecting piece 26, and integrated circuit board 24 can remove function module 23 relatively, thereby make function module 23 when receiving external force to rock, function module 23 removes relative integrated circuit board 24, and make the power that function module 23 self vibration produced can not pass through integrated circuit board 24 transmission to circuit board 22 with integrated circuit board 24 electric connection, avoid the damage of circuit board 22, thereby the reliability of case subassembly 2 and medical equipment 100 has been improved.
Referring to fig. 8, another chassis assembly 20 according to the present embodiment is provided, the chassis assembly 20 has substantially the same structure as the chassis assembly 2 according to the previous embodiment, and the difference is mainly that the connecting element 226 is an elastic element, one end of the connecting element 226 is fixedly connected to one of the function module 223 and the board 224, and the other end of the connecting element 226 is elastically connected to the other of the function module 23 and the board 24. Specifically, as shown in fig. 8, the connecting member 26 is an elastic column made of an elastic material, and the structure of the fixed connection between one end of the connecting member and the functional module 23 can refer to the foregoing embodiments, which are not described herein again, and the outer peripheral surface of the other end of the connecting member abuts against the first hole 224a of the board 224, and the other end of the connecting member can further include a limiting section, which abuts against the board 224. When the functional module 223 is vibrated, since the connecting member 226 has elasticity, the external force transmitted from the functional module 223 to the connecting member 226 is absorbed by the connecting member 226, in other words, the force generated by the vibration of the functional module 223 itself is absorbed by the elastic member and is prevented from being transmitted to the board 224. It will be appreciated that the functional module 223 itself may move relative to the board 224 by pressing the board 224 via the connecting member 226 when vibrating, and that the movement of the functional module 223 relative to the board 224 may include movement in the plane of the board 224 and/or in the thickness direction of the board 224, and the functional module 223 may gradually stop vibrating as the elastic member absorbs the external force. This connecting piece 226's structure passes through elastic connection on integrated circuit board 224, can enough make integrated circuit board 224 preferred connect on integrated circuit board 224, is difficult for droing, sets up the setting that need not spacing portion, can reduce the external force that transmits to integrated circuit board 224 through the absorption of elastic component self to the vibration power again.
The features mentioned above in the description, the claims and the drawings can be combined with one another in any desired manner, insofar as they are of significance within the scope of the invention. The advantages and features described for the chassis assemblies 2, 20 apply in a corresponding manner to the medical device 100.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
