Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] In the embodiment: by opening the battery compartment, the pre-assembled module battery 1 can be taken out for quick installation. In the past, the module battery 1 was quickly installed by adding installation plates 21 and clamping sliders 22 on both sides, and after sliding into the inside of the battery compartment, the battery compartment was closed to complete the replacement. Now the traditional installation plate 21 and clamping slider 22 are no longer used, but the installation plate 21 and clamping slider 22 are both provided in a hollow inner cavity 23 state that is hollow and connected inside. The clamping slider 22 is changed from one-piece to segmented, which does not affect the original sliding installation effect. Through the elastic tensioning assembly 24 inside the hollow inner cavity 23, the sliding and tensioning quick installation is realized. In the module battery 1 quick installation and pre-assembly link, the module battery 1 maintains a volume and shape close to the traditional one, reduces the workload of simultaneous adjustment of the inside of the battery compartment, realizes quick replacement of the aerial vehicle outdoors, and reduces the risk of energy shortage.

[0029] Specifically, as shown in Figure 1 , Figure 2 , Figure 5 , the splicing mechanism 3 includes an installation slot 31 opened on the front side of the module battery 1, and the rear side of the module battery 1 is fixedly connected with a clamping plate 32.

[0031] Specifically, as shown in Figure 1 , Figure 2 , Figure 5 , the inside of the stroke slot 34 is fixedly connected with a first telescopic rod 35, the outside of the first telescopic rod 35 is fixedly connected with a first compression spring 36, and the outside of the first telescopic rod 35 is fixedly connected with an arc-shaped extrusion block 37.

[0032] In the embodiment, the module battery 1 is pre-assembled according to the battery compartment capacity before the aerial vehicle reaches the artificial or automatic supply point. The front side of the module battery 1 shell is provided with a mounting groove 31, and the rear side is provided with a clamping plate 32. Both positions do not affect the use of the battery. When assembling, the rear clamping plate 32 of a group of module batteries 1 is inserted into the front mounting groove 31 of another group of module batteries 1 from top to bottom. During the clamping plate 32 is pressed down, the arc-shaped extrusion block 37 on both sides of the mounting groove 31 is extruded, the arc-shaped extrusion block 37 moves to the travel groove 34 on the inner side of the limiting strip 33, the first extension rod 35 and the first compression spring 36 are extruded to make them retract, and after the clamping plate 32 reaches the limit position, the arc-shaped extrusion block 37 is pushed back by the first extension rod 35 and the first compression spring 36. The clamping plate 32 is uniformly clamped from multiple points, the pre-assembly of insertion and elastic clamping is realized, the assembly structure is optimized from the original shell of the module battery 1, the volume and the length-width ratio of the battery are not changed, the battery compartment of the aerial vehicle does not need to be adjusted, and multiple groups of module batteries 1 can be supplemented at one time according to the size of the battery compartment.

[0033] Specifically, as shown in Figure 3 、 Figure 4 , the elastic tensioning assembly 24 includes a telescopic column 24a fixedly connected to the inner side of the hollow inner cavity 23. The telescopic column 24a is arranged on the inner side of the mounting plate 21. The outer side of the telescopic column 24a is fixedly connected with a tension spring 24b. The outer side of the telescopic column 24a is fixedly connected with a linkage plate 24c. The outer side of the linkage plate 24c is fixedly connected with a second extension rod 24d. The outer side of the second extension rod 24d is fixedly connected with a second compression spring 24e. The outer side of the second extension rod 24d is fixedly connected with a support block 24f. The support block 24f is arranged on the inner side of the clamping sliding block 22.

[0034] Specifically, as shown in Figure 3 、 Figure 4 , the inner side of the top of the clamping sliding block 22 is fixedly connected with a third extension rod 24g. The outer side of the third extension rod 24g is fixedly connected with a third compression spring 24h. The outer side of the third extension rod 24g is fixedly connected with a limiting protrusion 24i. The outer side of the limiting protrusion 24i is provided with an extrusion protrusion 24j. The extrusion protrusion 24j is slidingly connected to the inner side of the hollow inner cavity 23. The extrusion protrusion 24j is arranged on the outer side of the linkage plate 24c.

[0035] In the embodiment: by pushing the module battery 1 into the battery compartment, when it is pushed to the inner wall of the battery compartment, the extrusion protrusion 24j on the outer side of the inner wall mounting plate 21 first contacts the inner wall of the battery compartment. Normally, the extrusion protrusion 24j is extruded and limited by the limiting protrusion 24i on the inner side of the top clamping slider 22 supported by the third telescopic rod 24g and the third compression spring 24h. After contacting the inner wall of the battery compartment, the extrusion protrusion 24j slides to the hollow inner cavity 23 on the inner side of the mounting plate 21, the extrusion limiting protrusion 24i slides to the inner wall of the top clamping slider 22, thereby compressing the third telescopic rod 24g and the third compression spring 24h. When the extrusion protrusion 24j slides to the hollow inner cavity 23, the outer side linkage plate 24c is displaced to the side of the clamping slider 22 due to the increase in width, and at the same time, the telescopic column 24a and the tension spring 24b between the inner wall of the hollow inner cavity 23 on the inner side of the mounting plate 21 are tensioned. When the linkage plate 24c is displaced, the support block 24f connected by the second telescopic rod 24d and the second compression spring 24e also moves synchronously. The support block 24f is located in the area of the hollow inner cavity 23 of the clamping slider 22, and there is an opening on the outer side of the clamping slider 22. In this way, the extrusion protrusion 24j is pressed down, the linkage plate 24c drives the telescopic column 24a and the tension spring 24b to extend, the support block 24f is tightly supported outwardly to the inner wall of the battery compartment and compresses the second telescopic rod 24d and the second compression spring 24e, achieving buffer support, completing the quick installation of sliding connection and support. After installation is completed, the extrusion protrusion 24j is located in the hollow inner cavity 23, without occupying external space. When replacing, the outer side hook ring 4 of the extrusion protrusion 24j is pulled out by the traction or magnetic attraction structure inside the battery compartment to remove the limitation, and then the module battery 1 is removed by sliding connection.

[0036] Specifically, as shown in Figure 3 The top of the extrusion protrusion 24j is fixedly connected with a hook ring 4.

[0037] Specifically, as shown in Figure 1 , Figure 2 The top of the module battery 1 is fixedly connected with a foolproof electrode 5.

[0038] In the embodiment: by pulling the hook ring 4 on the outer side of the extrusion protrusion 24j through the traction structure or magnetic attraction structure inside the battery compartment, the hook ring 4 is pulled out to remove the limitation, and then the module battery 1 is removed by sliding connection. After confirming the foolproof electrode 5 of the module battery 1, the battery compartment is opened for quick replacement. The foolproof electrode 5 is a positive circular electrode.

[0039] Working principle: when the air vehicle is replaced with outdoor module battery 1, it can be pre-assembled according to the capacity of the battery compartment of the air vehicle before it reaches the artificial supply point or the automatic supply point. The pre-assembled module battery 1 is provided with a splicing structure on the front side and the rear side of the module battery 1 shell. The splicing structure is not connected with other connecting structure or self-adaptive clamp, but a mounting groove 31 is opened on the front side of the module battery 1 shell without affecting the use area of the module battery 1. A clamping plate 32 is provided on the rear side of the module battery 1 without affecting the use area by slotting and polishing. A group of clamping plates 32 on the rear side of the module battery 1 are inserted into the inner side of the mounting groove 31 on the front side of another group of module batteries 1 for pre-assembling. After the clamping plate 32 enters the mounting groove 31, the clamping plate 32 will extrude the arc-shaped extrusion block 37 on both sides of the insertion path during the downward process. Because the arc surface of the arc-shaped extrusion block 37 faces upward, when it is extruded by the clamping plate 32, it will move into the travel groove 34 inside the limiting strip 33 and extrude the first extension rod 35 between it and the travel groove 34 and the first compression spring 36 outside it to make it contract. When the clamping plate 32 reaches the limit distance and completes the insertion, the arc-shaped extrusion block 37 in the travel groove 34 inside the limiting strip 33 generates uniform point return force by the elastic potential energy of the first extension rod 35 and the first compression spring 36 outside it, so that the clamping plate 32 is uniformly clamped from multiple points to achieve the effect of pre-assembling by insertion and elastic clamping. The splicing structure is optimized from the original module battery 1 shell without affecting the original volume and aspect ratio of the module battery 1, avoiding the need to adjust the battery compartment of the air vehicle and supplementing multiple module batteries 1 at one time according to the size of the battery compartment. Secondly, after the air vehicle reaches the supply point, the module battery 1 is replaced quickly by confirming the foolproof electrode 5. The foolproof electrode 5 is a positive circular shape and a negative oval shape for shape differentiation. After the battery compartment is opened, one or more pre-assembled module batteries 1 are taken out for quick installation. The existing module battery 1 is usually installed by adding mounting plates 21 and clamping blocks 22 on both sides for sliding into the inner side of the battery compartment, and then the battery compartment is closed to complete the replacement. The traditional mounting plate 21 and clamping block 22 are no longer used, but are set as hollow and connected to form a hollow cavity 23. The clamping block 22 is segmented from the integral type, and the adjustment does not affect the original sliding installation effect. The module battery 1 is pushed to the inner side of the battery compartment, and then the extrusion block 24j on the inner wall side of the battery compartment and outside the mounting plate 21 is in contact with the inner wall of the battery compartment.The extrusion block 24j will slide from the outer side of the mounting plate 21 to the hollow inner cavity 23 of the inner side of the mounting plate 21, and extrude the limiting block 24i, so that it slides to the inner wall of the top clamping slider 22 and extrudes the third telescopic rod 24g and the third compression spring 24h outside the third telescopic rod 24g, and when the extrusion block 24j gradually slides into the hollow inner cavity 23, the width of the linkage plate 24c outside the extrusion block 24j gradually increases, so that it gradually displaces to the side close to the clamping slider 22, and tightens the telescopic column 24a and the extension spring 24b outside the telescopic column 24a between the inner wall of the hollow inner cavity 23 of the mounting plate 21 and the linkage plate 24c, and in the process of displacement of the linkage plate 24c, the support block 24f outside the linkage plate 24c is also moved at the same time through the second telescopic rod 24d and the second compression spring 24e outside the second telescopic rod 24d, and the support block 24f is arranged in the hollow inner cavity 23 of the clamping slider 22, and the opening is arranged outside the clamping slider 22. Therefore, through the above linkage, the extrusion block 24j is pressed down, the telescopic column 24a and the extension spring 24b outside the telescopic column 24a are extended through the linkage plate 24c, the support block 24f is tightly supported outwardly to the inner wall of the battery compartment and the second telescopic rod 24d and the second compression spring 24e outside the second telescopic rod 24d between the support block 24f and the linkage plate 24c, so as to achieve the effect of buffering and supporting the inner wall of the battery compartment. The above achieves the quick installation of sliding connection and supporting, and after complete installation, the extrusion block 24j is entirely arranged inside the hollow inner cavity 23, without occupying external space. When replacement is needed, the hook and loop 4 outside the extrusion block 24j is pulled through the traction structure or magnetic attraction structure inside the battery compartment, and after the extrusion block 24j is pulled out and released from the limiting position, the sliding connection is removed. The above makes the module battery 1 tend to the traditional size and shape in the aspects of quick installation and pre-assembly of the module battery 1, reduces the content of synchronous adjustment inside the battery compartment, and realizes the outdoor quick replacement of the aerial vehicle, reduces the risk of energy shortage.

[0040] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
