[0027] Please refer to Figures 1 to 5 The utility model proposes a vehicle-mounted charging device 100, wherein a mounting plate 101 is provided with at least three first limiting portions 102 for clamping a charging seat 11, and the mounting plate 101 further comprises at least one second limiting portion 103, each second limiting portion 103 is connected to at least one first limiting portion 102, and each first limiting portion 102 and each second limiting portion 103 are used to limit the movement of the charging seat 11 in a direction away from the mounting plate 101.

[0028] During the installation of the charging seat 11, the horizontal direction of the charging seat 11 is consistent with the horizontal direction of the mounting plate 101, and the first limiting portion 102 can effectively realize rapid positioning of the charging seat 11 installed in the horizontal direction of the mounting plate 101. At the same time, during the movement of the vehicle, multiple first limiting portions 102 can limit the movement of the charging seat 11 in the horizontal direction, and the second limiting portion 103 is used to limit the movement of the charging seat 11 in the vertical direction, that is, to quickly locate the height difference between the charging seat 11 and the mounting plate 101, so as to realize rapid installation. The first limiting portion 102 and the second limiting portion 103 can be in the form of fixed connection or integral molding, and the form of fixed connection can be welding, riveting, etc. In some embodiments, there may be multiple second limiting portions 103, and the height of the charging seat 11 may be limited by the second limiting portions 103, or other structures that can achieve height limitation of the charging seat 11, for example, the first limiting portion 102 in the fixed bracket 10 is arranged as four walls protruding around the mounting plate 101, and the second limiting portion 103 is a cover body that is detachably connected or rotatably connected to the first limiting portion 102. In this way, the fixed bracket 10 is a box body that can be opened on one side. By removing the second limiting portion 103 or rotating the second limiting portion 103, the charging seat 11 is slidably assembled into the box body from the opening, so as to achieve the purpose of quick installation and limiting the movement of the charging seat 11.

[0029] Please refer to Figure 4 and Figure 5 The charging stand 11 has a receiving cavity 112 for placing electronic equipment. The charging stand 11 has a transmission-connected resilient member 113 and a button 114 built therein. The electronic equipment is installed in the receiving cavity 112. The button 114 is used to control the resilient member 113 to extend from the inside of the charging stand 11 into the receiving cavity 112, and the resilient member 113 is used to push the electronic equipment to separate from the bottom surface of the receiving cavity 112. The charging stand 11 is provided with an interface for electrical connection with an external power source, and the interface can be inserted with an electric plug. A conductive member is also provided in the receiving cavity 112. The conductive member is used to electrically connect the electronic equipment to the external power source. The electronic equipment includes batteries, monitors, ventilators and other equipment. In an embodiment of the utility model, the charging seat 11 is provided with two accommodating cavities 112 for charging the battery. When the battery enters the accommodating cavity 112, the battery squeezes the resilient member 113 until it retracts into the interior of the charging seat 11. After charging is completed, the user presses the button 114 to control the resilient member 113 to pop out from the interior of the charging seat 11 into the accommodating cavity 112. The resilient member 113 pushes the battery to separate from the charging seat 11, making it easier for the user to take it.

[0030] In this embodiment, each second limiting portion 103 is arranged parallel to the mounting plate 101, and the outer surface of the charging seat 11 is concavely provided with a limiting groove 111 corresponding to the second limiting portion 103, and each second limiting portion 103 at least partially extends into each limiting groove 111 and abuts against the groove wall of the limiting groove 111. The mounting plate 101 is parallel to the horizontal plane of the vehicle and is installed on the vehicle. In other embodiments, the mounting plate 101 can also be installed on the vertical wall of the vehicle, and the charging seat 11 is hung on the mounting plate 101. The first limiting portion 102 and the second limiting portion 103 are fixedly connected or integrally formed. The first limiting portion 102 is fixedly connected or integrally formed with the mounting plate 101. The second limiting portion 103 and the mounting plate 101 remain parallel, and the distance between the second limiting portion 103 and the mounting plate 101 is the same as the height of the limiting groove 111. The limiting groove 111 has a movable space. The second limiting portion 103 can move horizontally or vertically in the movable space to facilitate the assembly of the charging seat 11 and the mounting plate 101. The user can move the charging seat 11 to make the second limiting portion 103 disengage from the limiting groove 111 to release the installation of the charging seat 11.

[0031] The number of the first limiting portion 102 and the second limiting portion 103 may be the same or different. The first limiting portion 102 is used to limit the movement of the charging seat 11 on the plane of the extension surface of the mounting plate 101, and the second limiting portion 103 is used to limit the movement of the charging seat 11 in a direction perpendicular to the extension surface of the mounting plate 101, so as to achieve the purpose of fixing and quickly positioning the charging seat 11. It can be understood that the limiting grooves 111 are set corresponding to the number of the second limiting portions 103, and the limiting grooves 111 can be set on multiple sides of the outer shell of the charging seat 11. In other embodiments, the limiting grooves 111 can also be set on the bottom surface where the charging seat 11 and the mounting plate 101 are assembled. The first limiting portion 102 protruding from the mounting plate 101 is plugged into and matched with the limiting grooves 111 set on the bottom surface to achieve fixed installation of the charging seat 11.

[0032] In one embodiment, each second limiting portion 103 is arranged parallel to the mounting plate 101, and the height of each second limiting portion 103 is the same as the height of the charging seat 11, and the second limiting portion 103 abuts against the top surface of the charging seat 11 away from the mounting plate 101. The height of each second limiting portion 103 is the same as the height of the charging seat 11, which plays a role in limiting the distance between the charging seat 11 and the mounting plate 101, and has the same positioning and limiting effect on the charging seat 11 as the second limiting portion 103 provided in the limiting groove 111. The second limiting portion 103 can be fixedly connected with the first limiting portion 102 in a one-to-one correspondence, and there is a gap between the second limiting portions 103 provided on both sides of the mounting plate 101 in the axial direction, providing an avoidance position for the electronic equipment installed in the accommodating cavity 112 of the charging seat 11, while limiting the charging seat 11, it also facilitates the installation and removal of the electronic equipment. The second limiting portion 103 can abut against the top surface of the charging seat 11, and can also be spaced a certain distance from the top surface of the charging seat 11, which is not limited here.

[0033] In another embodiment, the two ends of each second limiting portion 103 are respectively connected to the two first limiting portions 102 arranged on the opposite sides of the mounting plate 101. That is, the two first limiting portions 102 are connected through a second limiting portion 103, and the second limiting portion 103 can be arranged above the accommodating cavity 112. The position of the second limiting portion 103 can avoid the position of the accommodating cavity 112 of the charging seat 11, and is used to limit the movement of the charging seat 11 in the height direction. The second limiting portion 103 can also block the opening of part of the accommodating cavity 112, and can limit the electronic device installed in the charging seat 11 from leaving the accommodating cavity 112. In this case, the second limiting portion 103 and the first limiting portion 102 can be in a detachable connection form, such as a screw assembly connection, a latch, a snap connection, etc., or one end of the second limiting portion 103 can be rotatably connected to the first limiting portion 102. By rotating the second limiting portion 103, it is convenient to place the electronic device into the accommodating cavity 112, thereby enhancing the installation stability of the electronic device in the charging seat 11. The limiting and fixing functions of the first limiting portion 102 and the second limiting portion 103 on the charging stand 11 are the same as those in other embodiments, and will not be repeated here.

[0034] Furthermore, a first stopper 102 is provided at one end and both sides of the mounting plate 101 in the axial direction, and a second stopper 103 is provided on the first stopper 102 at one end of the mounting plate 101 in the axial direction. The charging seat 11 can be slidably assembled with the second stopper 103 from the other end of the mounting plate 101 in the axial direction. Figure 3There are four first limiting parts 102, which are respectively arranged on both sides and one end of the axial extension surface of the mounting plate 101, leaving a gap at the other end for the charging seat 11 to slide into the mounting plate 101. With this arrangement, when the charging seat 11 slides, the first limiting part 102 and the second limiting part 103 can position the charging seat 11 and limit the charging seat 11 from being separated from the mounting plate 101, which is convenient for the precise positioning and assembly of the charging seat 11 and the mounting plate 101.

[0035] In this embodiment, please refer to Figure 2 and Figure 3 The charging seat 11 and the fixing bracket 10 are provided with corresponding screw holes 104, and the screw holes 104 are equipped with captive screws 12. The charging seat 11 and the fixing bracket 10 are connected detachably by the captive screws 12. The captive screws 12 include a screw part, a rivet part and a spring, wherein the captive screw 12 is riveted to the mounting plate 101 by the rivet part, and the mounting plate 101 is provided with a screw hole 104 corresponding to the screw part, and the screw part can be freely screwed in and out of the screw hole 104, and the material of the screw part can be a metal material with high strength and rust resistance such as carbon steel and stainless steel, and the head shape of the screw part can be a cross or a slot, which is convenient for the tool to tighten it, and the rivet sleeve can be provided with embossed teeth for riveting and fixing with the mounting plate 101, and the spring connects the rivet part and the screw part, so that the captive screw 12 will not be separated from the mounting plate 101, and the spring has elastic potential energy, which is convenient for the extension and retraction of the screw.

[0036] Among them, the captive screw 12 also includes a hand-tightening sleeve arranged on the periphery of the screw part. The sleeve can be pressed with groove teeth, and the shape can be straight lines, threads or other lines. The purpose is to increase the friction of the hand-tightening sleeve to facilitate hand-tightening or manual tightening. The hand-tightening sleeve can be made of metal materials such as aluminum and stainless steel. The metal material of the hand-tightening sleeve can be rust-proofed to enhance the service life of the captive screw 12. The hand-tightening sleeve is turned to control the screw part to enter or move away from the screw hole 104. The captive screw 12 solves the problem of frequent disassembly of the screw, and is very convenient and practical.

[0037] Please refer to Figure 1In this embodiment, the fixing bracket 10 is provided with a support portion 105 protruding in a direction away from the first limiting portion 102, and the support portion 105 and the mounting plate 101 enclose an assembly space for assembling the captive screw 12. The support portion 105 can be integrally cast with the mounting plate 101, and the support portion 105 can be arranged on both sides or all sides of the mounting plate 101. The assembly space between the support portion 105 and the mounting plate 101 is conducive to assembling the captive screw 12 fixed on the mounting plate 101 with the charging seat 11. The assembly space provides an operating position for the hand-tightening sleeve in the captive screw 12, and the user can twist the hand-tightening sleeve in the assembly space to achieve locking of the captive screw 12. At the same time, the support portion 105 enhances the stability of the fixing bracket 10. On a moving vehicle, the vibration intensity of the vehicle transmitted to the charging seat 11 through the support portion 105 gradually decreases, and the charging seat 11 can remain stable.

[0038] Specifically, the captive screw 12 can be installed and fixed along the axial direction of the mounting plate 101, and fixed at one end along the direction in which the charging seat 11 and the mounting plate 101 are slidably assembled into the mounting plate 101 from one end away from the first limiting portion 102 and the second limiting portion 103 in the axial direction. After the charging seat 11 abuts against the first limiting portion 102, the screw hole 104 of the charging seat 11 and the screw hole 104 of the mounting plate 101 are quickly positioned, and then the hand sleeve is twisted to fix the charging seat 11 and the mounting plate 101, thereby enhancing the fixing stability of the charging seat 11 on the fixed bracket 10.

[0039] Furthermore, a fixing portion 106 is provided at one end of the support portion 105 away from the mounting plate 101, and the fixing portion 106 is kept parallel to the mounting plate 101 and is used to be detachably connected to the vehicle. The fixing portion 106 and the support portion can be fixedly connected or integrally formed. The fixing portion 106 is in the shape of a protruding mounting skirt, which is used to increase the connection area between the fixing bracket 10 and the vehicle and enhance the stability of the fixing bracket 10 and the charging seat 11 on the vehicle. The fixing portion 106 is provided with evenly spaced screw holes 104, and the vehicle is correspondingly provided with screw holes 104 in the same position, and the mounting surface of the vehicle and the fixing portion 106 are detachably connected by screws. When replacing an electronic device that needs to be charged or replacing other vehicles, the charging seat 11 can change its position at any time, which enhances the expansibility and practicality of the vehicle-mounted charging device 100. In other embodiments, the detachable connection between the fixing portion 106 and the vehicle can be in other forms, such as plug-in, hinged, magnetic connection, etc., which are not limited here.

[0040] Please refer to Figure 3In this embodiment, each first limiting portion 102 is elastic, and the mounting plate 101 is provided with a clearance space 1011 for each first limiting portion 102 to bend. The width of the first limiting portions 102 on opposite sides of the mounting plate 101 is adapted to the charging seat 11 of different widths. For a charging seat 11 whose width is slightly smaller than the width between the two first limiting portions 102, the two first limiting portions 102 can be bent toward each other and enter the clearance space 1011, so that the first limiting portion 102 is close to the outer shell of the charging seat 11, so as to achieve the purpose of limiting the charging seat 11. At the same time, the second limiting portion 103 can also be bent to fit the height of the charging seat 11 or the height of the limiting groove 111 of the charging seat 11.

[0041] 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.
