Detailed ways

The automatic quick plug-in mechanism of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows a jack assembly 10 of an automatic quick-connect mechanism 1 according to a first embodiment of the present invention. Wherein, the jack assembly 10 has certain expansion and retraction capabilities. As shown in FIG. 1 , the socket assembly 10 includes a socket body 101 , which is a hollow cylinder, and a cutout 108 is formed on the wall of the cylinder along its central axis. And a hoop spring 102 is respectively fixed at both ends of the jack body 101 . Preferably, the inner diameter of the hoop spring 102 is equal to or slightly larger than the outer diameter of the socket body 101 . In this way, when the plug body 301 whose end surface diameter is larger than the inner diameter of the outer port of the jack body 101 is inserted into the jack body 101, the jack body 101 can expand, and under the retraction force of the hoop spring 102, it can be The plug assembly 301 is fixed in the jack body 101 .

According to a preferred embodiment of the present invention, the notch 108 on the wall of the jack body 101 can be a through notch, that is, the jack body 101 is cut into two halves, and then the hoop spring 102 is used to fix the two halves.

According to another preferred embodiment of the present invention, the slit 108 on the wall of the socket body 101 may be a non-through slit, specifically, the slit 108 starts from the outer port of the socket body 101 along the central axis of the socket body 101 Open to the vicinity of the inner port of the jack body 101, but not through. In this case, the hoop spring may not be used, and only the elasticity of the material of the socket body 101 is used to realize expansion and retraction capabilities. However, it is preferable to adopt the hoop spring 102 to clamp the jack body 101 at both ends on the outer wall of the jack body 101 along the transverse direction of the jack body 101, which increases the retraction force of the jack body 101, thereby making the jack body 101 The fastening performance of the hole body 101 is better.

Wherein, according to a preferred embodiment of the present invention, the hoop spring 102 can be a standard clip spring, and the retraction force is preferably about 5 kg.

As can be seen from Fig. 1, a flange 107 is also provided on the outer wall of the jack body 101, and with the flange 107 as a boundary, the outer wall of the jack body 101 is divided into two parts 101a and 101b, front and rear, and the front outer wall part 101a is along the axis. The length in the axial direction is much smaller than the length in the axial direction of the rear outer wall portion 101b, and the flange 107 is also divided into two by the notch 108.

As shown in FIG. 1 , the socket assembly 10 further includes a conductive sheet 103 , a spring 104 , a washer 105 and a base 106 . The conductive sheet 103 includes a front vertical portion 103a, a rear vertical portion 103b and a horizontal portion 103c. The horizontal portion 103c is fixed on the base 106 . The front vertical portion 103a is smaller in height than the rear vertical portion 103b. The front vertical portion 103a includes a through hole (not shown) whose inner diameter is slightly larger than the outer diameter of the receptacle body 101 and smaller than the diameter of the flange 107 . The rear vertical portion 103b includes a positioning protrusion 109 at a lower portion. As shown in the figure, the positioning projection 109 is circular, and the center of the circle is opposite to the center of the through hole on the front vertical part 103a, that is, the connecting line of the two centers and the horizontal part 103c parallel. The positioning protrusion 109 can be in any shape, not limited to circular, including cylindrical, prismatic, conical, conical, semicircular and so on.

The spring 104 is positioned on the rear vertical portion 103b by means of the positioning protrusion 109, and the other end of the spring 104 abuts against the spacer 105, so that the spacer is pressed against the front vertical portion 103a.

Fig. 2 is a perspective view of the assembled jack assembly 10 according to the first embodiment of the present invention. As shown in FIG. 2 , the jack assembly 10 further includes a housing 110 . A through hole 111 is formed on the front end of the housing 110 . The diameter of the through hole 111 is slightly larger than the outer diameter of the socket body 101 but smaller than the diameter of the flange 107 . Moreover, the upper surface of the casing 110 also has an opening 112 for the rear vertical portion 101b to pass through, and the distance between the opening 112 and the front end of the casing 110 is such that the flange 107 is in close contact with the front vertical portion 101a, In order to achieve good conduction between the jack body 101 and the conductive sheet 103 . At this time, under the action of the spring 104, since the rear vertical part 103b is fixed by the housing 110 so that it cannot perform pitching movement, when the plug body 301 is inserted into the jack body 101, the plug body 301 will not move against the jack body 101. The reclining movement of the front vertical part 103a caused by axial thrust is hindered by the spring 104, and when the plug body 301 is fully inserted into the jack body 101 and stops pushing the jack 101, the front vertical part 103a can be held by the spring 104. Return to the initial vertical state under the action of the plug body 301, the good contact between the plug body 101 and the conductive sheet 103 is ensured.

As shown in FIG. 3 , a state in which the plug body 301 is inserted into the jack body 101 is shown. It can be seen from the figure that there are multiple through holes on the base 106 . When the housing 110 is installed, the housing 110 can be fixed on the base 106 with bolts, and these bolts will pass through the through holes of the base (as shown in Figure 2 ), so that the assembled sockets can continue to be assembled using these bolts. Assembly 10 is mounted on the wall of the box where the jack assembly is to be used.

Fig. 4 shows according to the socket assembly 20 of the automatic quick plug-in mechanism 1 of the second embodiment of the present invention, as shown in Fig. 4, utilizes wire spring to form the socket assembly according to another embodiment of the present invention, namely in A spring hole is made in the socket assembly, and the spring hole can expand and contract radially, thereby clamping the plug assembly, and the retraction force is preferably about 5 kg.

Specifically, as shown in FIG. 4 , the jack assembly 20 includes a jack body 201 , an outer casing 202 , a gland 203 , a positioning nut 204 and a fixing bolt 205 . The casing housing 202 has an inner hole 207 into which the jack body 201 is inserted. And the outer casing 202 has a flange end 209 and a threaded extension body 210, and has a threaded hole on the end face of the flange end 209, and the outer diameter of the flange end 209 is greater than the outer diameter of the threaded extension 210, and the flange The outer diameter of the end portion 209 may be the same as the outer diameter of the gland 203 . The gland 203 has a central hole 206 and two small-diameter bolt fixing through holes. The diameter of the central hole 206 is equal to or slightly larger than the inner diameter of the socket body 201 and smaller than the outer diameter of the socket body 201 . And on the side of the gland 203 facing the socket body 201 , an annular protrusion 208 is formed around the circumference of the central hole 206 (as shown in FIG. 5 ). The inner diameter of the annular protrusion 208 is the same as that of the central hole 206 . The outer diameter of the annular protrusion 208 is smaller than the inner diameter of the inner hole 207 of the casing shell 202 and larger than the outer diameter of the socket body 101 . In this way, after the jack body 201 is inserted into the inner hole 207 of the outer casing 202, the gland 203 is covered on the end surface of the flange end 209 of the outer casing 202, so that the annular protrusion 208 is inserted into the inner hole 207. In order to support the jack body 201 and prevent the jack body 201 from being taken out of the inner hole 207 when the plug is pulled out from the jack body 201 . And utilize fixing bolt 205 to go through the fixing through hole on the top cover 203 and screw into the threaded hole on the end surface of flange end 207, and the gland is fixed on the end surface of flange end 209. Moreover, as shown in FIG. 5 , the inner hole 207 of the outer casing 202 is composed of two inner hole parts 211 and 212 whose central axes coincide, and the large-diameter inner hole part 211 into which the jack body 201 is inserted has a larger diameter. The diameter is equal to or slightly larger than the outer diameter of the socket body 201 . The small-diameter inner hole portion 212 is coaxial and communicated with the large-diameter inner hole portion 211, but the diameter of the small-diameter inner hole portion 212 is equal to or slightly larger than the inner diameter of the socket body 201 and is equal to or slightly larger than the plug body 301 inserted into the socket body 201 The maximum diameter of the part in the center is smaller than the outer diameter of the socket body 201 at the same time. Thus, a junction between the small-diameter inner hole portion 212 and the large-diameter inner hole portion 211 forms a stepped surface.

The positioning nut 204 is screwed on the outer casing by means of threads on the outer surface of the threaded extension body 210 to fix the jack assembly 20 on the box wall.

The specific structure and forming process of the socket body 201 according to the second embodiment of the present invention will be described below with reference to FIG. 6 and FIG. 7 . FIG. 6 shows the wire spring inner body 2011 of the jack body 201 , and FIG. 7 shows the jack body 201 . As shown in FIG. 6 , the inner body 2011 of the wire spring is formed by bending the wire spring into a cylindrical shape and turning the two ends of the cylinder toward the middle of the cylinder. In this way, the outer diameter of the middle part of the wire spring inner body 2011 is smaller than the outer diameters of both ends, so that the middle part of the wire spring inner body 2011 has a space to expand radially outward, and the plug body 301 is inserted into the jack body At this time, the middle part of the wire spring inner body 2011 can freely expand radially outward under the extrusion of the plug body 301 . As shown in Figure 7, a wire spring outer body 2012 is respectively sleeved at both ends of the wire spring inner body 2011, and the inner diameters of the two wire spring outer bodies 2012 are equal to or slightly larger than the outer diameters of the two ends of the wire spring inner body 2011, and A predetermined gap 2013 is left between the two wire spring outer bodies 2012 .

After inserting the socket body 201 into the inner hole 207 of the casing housing 202, when the gland 203 is installed, the wire spring outer body 2012 is sandwiched between the annular protrusion 208 of the gland 203 and the small-diameter inner hole portion 212 During this time, when the bolt 205 is tightened, the annular protrusion 208 moves into the inner hole 207, so that the two wire spring outer bodies 2012 gradually approach each other until they are close together, that is, until the gap 2013 disappears. In this way, the free space for radial expansion of the middle part of the inner body 2011 of the wire spring is ensured and the elastic force and retraction force of the inner body 2011 of the wire spring are improved.

The structure of the plug assembly 30 will be described below with reference to FIGS. 3 and 8 .

FIG. 8 shows the plug body 301 of the plug assembly 30 . The plug body 301 includes a plug end 304 , a locking ring 302 , a plug fixing part 305 and a plug connecting part 303 with threads. Wherein, the plug end 304 includes a conical tip 3041 and a cylindrical body 3042 . As shown in FIG. 3 , the plug assembly 30 further includes an inner seat 306 , an outer seat 307 and an elastic centering ring 308 . The inner seat 306 , the outer seat 307 and the elastic centering ring 308 all have central holes, the plug fixing part 305 of the plug body is inserted into these central holes, and the inner seat 306 is supported by the locking ring 302 . When the plug assembly 30 is installed in the through hole on the wall of the box, the wall of the box is clamped by the inner seat 306 and the outer seat 307, so that the elastic centering ring 308 is in the through hole on the wall of the box. In this way, when jack assembly 10 or 20 and plug assembly 30 are automatically plugged in, when there is matching deviation between jack body 101 or 201 and plug end 304 due to non-concentricity, because plug end 304 has a conical The top 3041, as long as the conical top 3041 is the side wall of the inner hole of the jack body 101 or 201, the plug end 304 can enter the jack body 101 or 201 smoothly with the help of the elastic centering ring 308. This is because, when the plug end 304 and the socket body 101 or 201 are not concentric when plugged in, the side wall of the inner hole of the conical top 3041 touching the socket body 101 or 102 will produce a The extrusion component force of the plug end 304, this extrusion component force can be transmitted to the elastic centering ring 308, and because the elastic centering ring 308 has elasticity and is in the same plane with the box wall and is in contact with each other, it can be The inner seat 306 and the outer seat 307 move correspondingly along the direction perpendicular to the plug body, so that the plug body 301 can produce corresponding lateral movement, so that the plug end 304 can be inserted into the socket body 101 or 201 finally. In this way, under the action of the elastic centering ring 308, the error caused by the misalignment between the plug body 301 and the jack body 101 or 201 is absorbed, making it easy to insert and separate. At the same time, the elastic centering ring 308 also absorbs the vibration of the battery pack relative to the outer box, preventing relative movement between the plug and the socket. Needless to say, the socket can also use an elastic centering ring at the same time as required. The elastic centering ring 308 can be made of any elastic material, such as silicone and the like.

The above two implementations can realize the neck tightening plug assembly. The plug assembly can be designed as cylindrical and tapered pins according to requirements, and the socket assembly can also be designed as cylindrical holes and tapered holes. The components described above, except the elastic centering ring, can be made of metals with good electrical conductivity, such as copper, of course not limited to copper, and gold, silver and other metals can be used as needed.

As shown in FIG. 9 , the battery pack 40 according to the present invention is equipped with the socket assembly 10 or 20 according to the present invention, and also includes a positioning pin 402 and a buffer pad 403 on the same end face as the socket assembly 10 or 20 . The jack assembly 10 or 20 is electrically connected to the positive and negative electrodes of the battery pack 40 .

As shown in Figure 10, the rear end face of the battery box 50 according to the present invention is equipped with the plug assembly 30 according to the present invention, and the position of these two plug assemblies 30 is consistent with the plug assembly 10 of the present invention on the rear end face of the battery pack 40. or 20 corresponding to the position. And on the rear end face of the battery box according to the present invention, a positioning hole 501 is also provided for inserting the positioning pin 402 on the rear end face of the battery pack 40 for realizing the connection between the plug assembly 30 and the jack assembly 10 or 20. Accurate positioning. FIG. 11 is a perspective view of the battery case 50 according to the present invention viewed from another angle.

As shown in FIG. 12 , when the battery pack 40 is assembled into the battery box 50 , the jack assembly 10 or 20 will be accurately and automatically inserted into the plug assembly 30 and the clamping ability of the jack assembly 10 or 20 can be used to make the The battery pack 40 is fixed in the battery box. This is a so-called drawer-type battery box, which is the same as the pull-out mode of the furniture table drawer. After unlocking, the drawer can be pulled out and separated from the table. After the assembly is completed, the threaded end of the plug assembly 30 of the automatic quick-connect mechanism facing the outside of the battery box 50 is the positive and negative poles for external output. The positive pole and the negative pole are connected to the jack assembly 10 or 20 on the battery pack 40 through the plug terminal 304 of the plug assembly 30 to obtain power output. During the plugging process, the positioning pin 402 is used to guide the plugging.

The thread of the exposed plug connection part 303 of the plug assembly 30 can be connected to the power cord. In order to ensure that the cord does not constrain the vibration of the plug, the cord is fixed on the outer box after leaving a good margin, so that the battery pack 40 is relatively stable with respect to the battery. When the case 50 has a gap to vibrate, the neck clamping force of the jack assembly 10 or 20 is greater than the deformation force of the elastic silicone ring 308 and the external flexible wire, so the normal power transmission work of the plug and the jack will not be affected. Then, the flexible wire fixed end of the battery box 50 leaves a margin to be connected with the vehicle body, so that when the battery box 50 vibrates relative to the vehicle body, it will not affect the normal power transmission work of the plug jack.

The successful realization of such an automatic quick plug-in mechanism solves the technical key of the so-called "automatic quick plug-in drawer battery box", realizes the quick loading and unloading performance of the battery pack, solves the safe application of lithium batteries, and promotes the development of electric vehicles.
