[0025] Example:

[0026] See also Figures 1 to 5 In this embodiment, a magnetic electrical connection device includes: a bracket 100, a fixing device 200 detachably connected to the bracket 100, and a magnetic plug 300;

[0027] The fixing device 200 has an assembly through hole 230 that passes through both ends. The fixing device 200 has a plurality of elastic clips 240 protruding from the periphery to the inner wall of the assembly through hole 230. The head of the magnetic plug 300 is inserted into the assembly through hole 230. The head of the magnetic plug 300 is provided with a plurality of assembly grooves 320 that match the elastic clips 240 along the length extension direction. The elastic clips 240 are clipped to one end of the assembly groove 320 away from the head of the magnetic plug 300.

[0028] In this embodiment, the head of the magnetic plug 300 is plugged into the assembly through hole 230 on the fixing device 200. When the head of the magnetic plug 300 is plugged into place, the elastic clamping piece 240 on the fixing device 200 can clamp the magnetic plug 300, and the fixing device 200 can be detachably connected to the bracket 100, so that the magnetic plug 300 can be quickly plugged in and out, and different fixing devices 200 can be replaced according to different magnetic plugs 300 without disassembling the entire bracket 100. The magnetic electrical connection device in the utility model is simple to plug in and out, easy to disassemble and assemble, and can be quickly disassembled when not in use, thereby increasing the interior space of the ambulance.

[0029] Specifically, Figure 5 As shown, the head of the magnetic plug 300 is used to magnetically attract and electrically connect to the device to be powered, and the tail of the magnetic plug 300 is connected to the cable. The end of the head of the magnetic plug 300 close to the tail is gradually reduced and has protruding textures all around, which is used to increase the friction of the magnetic plug 300 and facilitate the user to hold it.

[0030] Furthermore, if Figures 3 to 5 As shown, at least one positioning member 310 protrudes at uneven intervals around the magnetic plug 300, and the inner wall of the assembly through hole 230 is also provided with at least one positioning groove 231 extending along the length direction, and each positioning groove 231 at least passes through the surface of the fixing device 200 facing the tail side of the magnetic plug 300.

[0031] As an example, the purpose of providing the positioning members 310 around the magnetic plug 300 is to prevent the magnetic plug 300 from being reversely plugged into the assembly through hole 230, which is a foolproof design. Among them, if there are multiple positioning members 310 protruding from the magnetic plug 300, the cross-sectional shapes of each positioning member 310 can be the same in the direction perpendicular to the axis of the magnetic plug 300, and each positioning member 310 protrudes from the magnetic plug 300 at non-uniform intervals to achieve the effect of foolproof positioning. The cross-sectional shapes of each positioning member 310 can be different, and each positioning member 310 with different cross-sectional shapes can be uniformly or non-uniformly spaced to protrude from the magnetic plug 300 to achieve the effect of foolproof positioning.

[0032] Each positioning groove 231 at least passes through the surface of the fixing device 200 facing the tail side of the magnetic plug 300 to ensure that the positioning member 310 can slide along the length extension direction of the equipment channel so that the head of the magnetic plug 300 can be plugged into the fixing device 200.

[0033] It should be understood that each positioning groove 231 can penetrate along the thickness direction of the fixing device 200 to the surface of the two ends of the fixing device 200, but preferably each positioning groove 231 only penetrates to the surface of the fixing device 200 facing the tail side of the magnetic plug 300, so that when the head of the magnetic plug 300 is plugged into the fixing device 200, the end of the positioning groove 231 that does not penetrate to the surface of the fixing device 200 can play a limiting role, and the auxiliary elastic clip 240 fixes the magnetic plug 300.

[0034] Furthermore, if Figure 5 As shown, the positioning member 310 extends in length from the head portion toward the tail portion of the magnetic plug 300. In this embodiment, the positioning member 310 is a strip-shaped protrusion, and the strip-shaped protrusion extends in length from the head portion toward the tail portion of the magnetic plug 300.

[0035] Furthermore, if Figure 4 As shown, in a direction perpendicular to the axis of the assembly through hole 230 , the cross section of the fixture 200 is asymmetrically arranged, or the symmetry center of the cross section of the assembly through hole 230 does not overlap with the symmetry center of the cross section of the fixture 200 .

[0036] As an example, in a direction perpendicular to the axis of the assembly through hole 230, the cross section of the fixture 200 can be asymmetrically arranged, and the fixture 200 can be assembled to the bracket 100 at a preset assembly angle. The asymmetrical arrangement plays a role in foolproof positioning, and avoids the fixture 200 from being assembled to the bracket 100 in reverse.

[0037] Alternatively, the symmetric center of the cross section of the fixing device 200 does not overlap with the symmetric center of the cross section of the assembly through hole 230, which can also prevent the fixing device 200 from being reversely assembled to the bracket 100, such as in the present embodiment. Figure 2 As shown, in the direction perpendicular to the axis of the assembly through hole 230, the cross-section of the fixing device 200 is rectangular, the cross-section of the assembly through hole 230 is circular, and the center of the cross-section of the assembly through hole 230 only passes through one symmetry axis of the cross-section of the fixing device 200. The bracket 100 is provided with an assembly groove 121 that matches the fixing device 200. The fixing device 200 needs to be adjusted to a specific angle to be assembled into the assembly groove 121, forming a fool-proof design.

[0038] Furthermore, if Figures 2 to 4As shown, the fixing device 200 includes a fixing seat 210 with a through hole opened along the thickness direction and a fixing sleeve 220 protruding from one side of the fixing seat 210 . The fixing sleeve 220 is coaxially arranged with the through hole of the fixing seat 210 and connected to form an assembly through hole 230 .

[0039] Furthermore, if Figure 3 and 5 As shown, each elastic clip 240 protrudes from the periphery of the fixing base 210 toward the inner wall of the through hole of the fixing base 210, and the protruding portion of the elastic clip 240 can be elastically retracted. A clip groove 321 is formed at one end of each assembly groove 320 away from the head of the magnetic plug 300, and the clip groove 321 matches the protruding portion of the elastic clip 240.

[0040] In this embodiment, since the protruding portion of the elastic clamping member 240 is elastically retractable, the clamping groove 321 is located at the end of the assembly groove 320 away from the head of the magnetic plug 300. When the magnetic plug 300 is inserted into the fixing device 200 to a certain depth, the protruding portion of the elastic clamping member 240 will be extended to be clamped in the clamping groove 321. By presetting the elastic force in the elastic clamping member 240, setting the protruding portion of the elastic clamping member 240 as an arc surface or an inclined surface, and / or setting the groove wall of the clamping groove 321 as an arc surface or an inclined surface, it is ensured that when the magnetic plug 300 is pulled out of the fixing device 200 with force, the protruding portion of the elastic clamping member 240 can be retracted, thereby achieving quick plugging and unplugging.

[0041] Furthermore, if Figures 3-4 As shown, the elastic clamping member 240 is a ball plunger, and the groove wall of the clamping groove 321 is arranged in an inclined surface and / or an arc surface.

[0042] The ball plunger, also known as the spring plunger or positioning bead / column, is a part that has a spring installed inside the thread and adjusts the preload and achieves the positioning function by controlling the screw-in depth. Figure 4 As shown, ball plungers are installed in the center of the three surfaces around the fixing seat 210, and the groove wall of the snap-in groove 321 matches the shape of the bead of the ball plunger. The ball plunger sets a pre-pressure for the bead by controlling the depth of the thread selection. When the user applies force to pull out the magnetic plug 300 from the fixing device 200, the bead of the ball plunger can be retracted, so that the magnetic plug 300 can be quickly plugged in and out, and the operation is convenient.

[0043] Furthermore, if Figure 2 As shown, the bracket 100 is provided with a through assembly groove 121 along the thickness direction, the fixing device 200 can be detachably assembled in the assembly groove 121 , and the length extension direction of the assembly through hole 230 is parallel to the thickness direction of the bracket 100 .

[0044] Specifically, the bracket 100 can fix the device to be powered, and align the charging interface of the device to be powered with the assembly through hole 230, so that the magnetic plug 300 can be quickly aligned and plugged into the charging interface of the device to be powered.

[0045] Furthermore, if Figure 2 As shown, the assembly groove 121 includes a first groove and a second groove connected to each other, the first groove matches the fixing seat 210, the second groove matches the fixing sleeve 220, and the fixing seat 210 is threadedly connected to the groove wall on the first groove connected to the second groove. The fixing device 200 can be disassembled and assembled on the side of the bracket 100 away from the magnetic plug 300.

[0046] In other embodiments, the fixing base 210 may be fixed to the bracket 100 in various detachable ways such as snap connection or pin connection.

[0047] Furthermore, if Figure 1 As shown, the bracket 100 includes a base 110 and a connector base 120 connected to the base 110. There is an angle between the base 110 and the connector base 120. The base 110 and the connector base 120 are used to fix the device to be powered, and the fixing device 200 is detachably connected to the connector base 120.

[0048] It should be understood that the fixing device 200 can be assembled on any supporting device such as a shell, box or wall with a certain thickness, and is not limited to the bracket 100 having a base 110 and a connector seat 120. Those skilled in the art can set the supporting device according to the specific shape of the equipment to be powered.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
