[0026] Example:

[0027] like Figure 1-4 As shown, in this embodiment, the first embodiment provides a car charger bracket for charging a medical device, and the medical device includes a locking portion 02 for locking and fixing with the car charger bracket. The car charger bracket includes a base 1, a frame 2 fixed to the base 1, a charging component 3 and a mounting component 4 respectively fixed to the frame 2; a first assembly port is provided on the side of the frame 2, and an installation cavity is formed in the frame 2; the installation component 4 includes an elastic component fixed in the installation cavity and a movable part 44 connected to the elastic component and extending outward from the first assembly port; an assembly space for installing a medical device is formed between the base 1 and the frame 2, and the movable part 44 is used to move between the installation cavity and the assembly space under the elastic force of the elastic component; when the medical device is installed in the assembly space, the end of the movable part 44 away from the elastic component is locked with the locking portion 02.

[0028] Specifically, the elastic component is connected to the movable part 44, and the movable part 44 can move between the installation cavity and the assembly space along the first assembly port under the action of external force, and the locking fixation of the vehicle charger bracket and the medical device is realized by the movable part 44, that is, during installation, the movable part 44 can be first moved into the frame body along the first assembly port under the action of external force, and when the positions of the vehicle charger bracket and the medical device are aligned (when the first assembly port and the locking part 02 are aligned), the movable part 44 automatically moves to the outside of the first assembly port under the rebound action of the elastic component, and then can realize the locking cooperation with the locking part 02; the vehicle charger bracket and the medical device can be installed and fixed without performing tedious operations such as tightening screws, and the operation is simple, convenient and fast.

[0029] In this embodiment, the elastic component includes a spring 41 fixed in the installation cavity and a connecting member 42 connected to one end of the spring 41, a guide hole 421 is opened in the connecting member 42, and the movable member 44 is movably connected to the guide hole 421; the guide hole 421 has a first guide inclined surface, when the connecting member 42 moves back and forth along the extension and contraction direction of the spring 41, the guide hole 421 drives the movable member 44 to move along the first guide inclined surface, and the moving direction of the movable member 44 is perpendicular to the extension and contraction direction of the spring 41.

[0030] Specifically, a recessed groove fixed to one end of the spring 41 is provided in the installation cavity, and the spring 41 is installed vertically. One or more springs 41 may be provided, preferably two. When the connecting member 42 moves under the action of an external force and compresses the spring 41 downward, the first guide slope will squeeze the movable member 44 during the movement, and the movable member 44 moves along the first assembly port into the installation cavity under the extrusion force, and then the position of the car charger bracket and the medical device is aligned (the first assembly port and the locking portion 02 are aligned); after the position is aligned, the external force applied to the connecting member 42 is cancelled, the spring 41 rebounds, and the connecting member 42 moves accordingly, and the movable member 44 retreats to its original position along the first guide slope under the extrusion force of the first guide slope. At this time, the end of the movable member 44 away from the connecting member 42 extends out of the first assembly port and is locked and fixed with the locking portion 02 outside the first assembly port.

[0031] In this embodiment, the movable member 44 includes a locking block 442 movably assembled in the first assembly port and a bearing 441 vertically connected to the locking block 442; a slideway 211 is provided on the side wall of the installation cavity, and one end of the bearing 441 away from the locking block 442 is installed in the slideway 211; the extension direction of the slideway 211 is parallel to the telescopic movement direction of the locking block 442. The bearing 441 and the locking block 442 can be fixed by screws, and the slideway 211 is composed of two bosses and the side wall of the installation cavity. The two bosses are arranged at intervals up and down, and extend from the side wall of the installation cavity into the installation cavity respectively; one end of the bearing 441 away from the locking block 442 is installed between the two bosses, so that the boss of the slideway 211 can form a height position restriction on the bearing 441, so that when the bearing 441 is squeezed by the first guide slope, it can only move in the horizontal direction along the boss, thereby driving the locking block 442 to move on the first assembly port.

[0032] In this embodiment, the connecting part 42 is provided with two symmetrical guide holes 421, and the number of the bearings 441 and the locking blocks 442 is two, and each bearing 441 passes through one of the guide holes 421 and is connected with the corresponding locking blocks 442. That is, the two sides of the frame 2 are respectively provided with corresponding first assembly ports for the locking blocks 442 to enter and exit. When the connecting member 42 moves up and down under the action of an external force, the bearings 441 are directionally displaced under the common guiding action of the first guiding slope and the slideway 211, that is, the two bearings 441 move in the direction of approaching or moving away from each other under the guiding action, thereby driving the two locking blocks 442 to move to the corresponding positions on the first assembly port to achieve unlocking or locking with the medical device. Of course, in some other embodiments, the bearings 441 and the locking blocks 442 can also be correspondingly provided with three, four or more, which is not limited here. It can be understood that the number of slideways 211 corresponds to the number of bearings 441. Of course, in some specific embodiments, only one slideway may be provided, and two symmetrically arranged bearings 441 may share the same slideway 211 .

[0033] In this embodiment, the end of the locking block 442 away from the bearing 441 is formed with a second guiding bevel facing the assembly space. When the spring 41 is in a natural state, the end of the locking block 442 away from the bearing 441 will extend out of the first assembly port, at which time the edge of the second guiding bevel is tangent to or intersects with the edge of the first assembly port. In the process of aligning the position of the vehicle charger bracket and the medical device, the locking portion 02 first contacts the second guiding bevel, and then can squeeze the second guiding bevel under the guiding action of the second guiding bevel and gradually press the entire locking block 442 back into the installation cavity and the first assembly port. The locking block 442 can be retracted into the frame 2 without applying additional force to the connecting member 42, and the operation of aligning the position of the vehicle charger bracket and the medical device is more convenient.

[0034] In this embodiment, a second assembly opening is provided at the top of the installation cavity, and the installation assembly 4 further includes an unlocking member 43, one end of which passes through the second assembly opening and is connected to the end of the connecting member 42 away from the spring 41; when the unlocking member 43 is moved into the assembly cavity by external pressure so that the installation assembly 4 is in an unlocked state, the locking block 442 is located in the frame 2. The unlocking member 43 and the connecting member 42 can be an integrally formed structure, or two separate structures connected and fixed by means of a snap connection or a screw connection. By applying downward pressure to the unlocking member 43, the connecting member 42 can be pushed to move, and then the movable member 44 can be driven to move by the guiding effect of the guide hole 421 to achieve unlocking; when the pressure applied to the unlocking member 43 is removed, the connecting member 42 and the movable member 44 automatically return to their original positions under the elastic force of the spring 41 to achieve locking, which is convenient to operate and has good locking stability. In a specific implementation of this embodiment, the frame 2 is a cubic frame 2, and the frame 2 includes a shell 21 fixed on the base 1 and a fixed cover 22 covering the top of the shell 21. The shell 21 and the fixed cover 22 enclose an installation cavity, and the first assembly port and the second assembly port are both arranged on the fixed cover 22.

[0035] In this embodiment, a limiting platform is formed on the peripheral side of one end of the unlocking member 43 away from the connecting portion 42, and the projection contour of the limiting platform in the top view direction is at least partially located outside the projection contour of the second assembly port in the top view direction. The setting of the limiting platform can prevent the user from directly pressing the entire unlocking key into the installation cavity with excessive force during the process of pressing the unlocking member 43, thereby damaging the installation assembly 4. At the same time, the setting of the limiting platform increases the contact surface area of ​​the unlocking member 43 for operation, which is conducive to improving the hand feel and making the operation more convenient.

[0036] In this embodiment, the base 1 includes a base plate 11, a positioning component and a buffer pad 12 arranged on the base plate 11, and the positioning component is used to connect and fix with the medical device. The setting of the buffer pad 12 can prevent the medical device from being damaged by bumps during placement. The edge area of ​​the base plate 11 is provided with threaded holes for fixing with the frame 2, so that the base plate 11 and the frame 2 can be fixed by screws. In addition, in this embodiment, both the frame 2 and the base plate 11 are provided with assembly holes 15 for fixing with the ambulance, that is, the frame 2 and the base plate 11 can be fixed with the ambulance, and when the car charger bracket is installed on the ambulance as needed, the installation is firm. It can be seen that the car charger bracket provided in this embodiment can be installed and fixed with the medical device through the installation component 4 and the base 1, and has a simple structure, small size, low cost and reliable performance.

[0037] Further, in this embodiment, the positioning assembly includes a limiting plate arranged around the edge area of ​​the bottom plate 11, and / or a limiting column 14 arranged in the middle area of ​​the bottom plate 11. Optionally, the limiting plate and the bottom plate 11 can be fixed by screws, or by welding, etc. In addition, the limiting plate and the bottom plate 11 can also be an integrally formed connection structure. In one embodiment, a plurality of limiting plates can be arranged at intervals in the edge area of ​​the bottom plate 11, so that the limiting plates, the bottom plate 11, and the frame 2 are enclosed to form an assembly space adapted to the shape of the medical device. Optionally, the medical device can also be provided with a mounting hole, so that the position of the mounting hole arranged on the position of the medical device on the bottom plate 11 corresponds to the limiting column 14, and the bottom of the medical device and the base 1 can also be fixed by the cooperation of the mounting hole and the limiting column 14. In a specific embodiment of this embodiment, three limiting plates are arranged at intervals in the edge area of ​​the bottom plate 11, and two spaced limiting columns 14 are arranged in the middle area of ​​the bottom plate 11, so that the car charger bracket and the medical device can be firmly fixed.

[0038] In this embodiment, the charging assembly 3 includes a power supply socket 31 fixed in the installation cavity and a charging socket 32 ​​fixed outside the frame 2 and facing the assembly space. The power supply socket 31 is electrically connected to the charging socket 32; the charging socket 32 ​​is provided with a charging interface 321 for connecting to the medical device. The frame 2 includes a shell 21 fixed on the base 1 and a fixed cover 22 covering the top of the shell 21. The shell 21 is provided with a third assembly port and a fourth assembly port. The power supply socket 31 is installed in the shell 21 and its power supply interface is located on the third assembly port. The power supply socket 31 can be connected to the car charger male socket through the power supply interface. The charging socket 32 ​​is installed outside the fourth assembly port, and the power supply socket 31 and the charging socket 32 ​​are electrically connected. After the medical device is installed on the car charger bracket and the power supply socket 31 is powered on, the medical device can be powered for use.

[0039] like Figure 4 As shown, the second embodiment provides a charging system, including a medical device and a car charging bracket as described in the first aspect of the present application.

[0040] Specifically, the main body 01 is provided with a charging connection part connected to the charging interface 321 connected to the charging socket 32. The locking part 02 is arranged on the side where the charging connection part of the medical device is located, and a card-embedded groove adapted to the shape of the fixed cover 22 is formed on the locking part 02, and a lock hole adapted to the shape of the lock block 442 is opened on the locking part 02. Before the position of the car charger bracket and the medical device is aligned, the lock block 442 must be moved back into the frame 2. When the position of the car charger bracket and the medical device is aligned, the side of the frame 2 facing the assembly space and the two sides where the first assembly port is located are respectively engaged with the card-embedded groove of the locking part 02, and the first assembly port and the lock hole are opposite. At this time, the spring 41 is restored to the natural state, and the lock block 442 will move out of the first assembly port under the action of the connecting member 42 and the bearing 441 and enter the corresponding lock hole, so that the locking and fixing with the locking part 02 can be achieved. When the medical device needs to be removed, the medical device can be taken out of the assembly space by pressing the unlocking key, which is simple to operate.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
