Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of the present application.

[0043] Currently, loaders are typically fuel-powered, with a small number now battery-powered. However, due to limitations in the loader's frame structure, the battery box is simply placed and mounted on the base via a mounting structure. The base lacks a corresponding positioning mechanism for the battery box, resulting in significant deviations in the battery box's installation position. This can lead to issues with the mounting structure, which in turn hinders installation. This application addresses these issues by proposing a vehicle-mounted battery mounting assembly and loader.

[0044] First, refer to Figures 1 to 10 , an embodiment of the present invention provides a vehicle-mounted battery installation assembly, which is applied to a loader, including: a battery box 10, including a box body 11 and a protrusion 12 arranged at the bottom of the box body 11, the box body 11 includes a first bottom frame 13, the first bottom frame 13 includes four corners 19 located at the four corners of the first bottom frame 13, and a positioning groove 121 is provided on the protrusion 12; a first battery base 20, which is used to be set on the loader, and the first battery base 20 is provided with a secondary positioning pin 21 that cooperates with the positioning groove 121, and the secondary positioning pin 21 is used to extend into the positioning groove 121; a second battery base 30, which is used to be set on the loader, is provided with two, and the two second battery bases 30 are respectively located on both sides of the length direction of the first battery base 20, and each second battery base 50 is provided with two first-level limiting portions 31, the first-level limiting portion 31 is used to cooperate with the corner portion 19, and the height of the first-level limiting portion 31 is greater than the height of the second-level positioning pin 21.

[0045] Specifically, the battery box 10 can be a battery-swap battery box. The discharged battery-swap battery box can be removed and placed on the charging station for charging. The charged battery-swap battery box can be reinstalled on the first battery base 20 and the second battery base 30 on the loader. Therefore, it is necessary to ensure the positioning accuracy of the battery box 10 during installation to facilitate the installation of the battery box 10. The battery box 10 can be placed on the loader by hoisting during installation. The battery box 10 includes a plurality of battery packs 17, and the battery box 10 is used to output electrical energy. The battery box 10 has a length direction, a width direction and a height direction, and its length direction, width direction and height direction are perpendicular to each other. The length direction of the battery box 10 can refer to Figure 1 The height direction of the battery box 10 can be referred to the direction indicated by the arrow B in FIG. Figure 1 The length, width, and height of the housing 11 are respectively consistent with those of the battery box 10. The length, width, and height of the protrusion 12 are consistent with the width of the battery box 10, the width of the protrusion 12 is consistent with the length of the battery box 10, and the height of the protrusion 12 is consistent with the height of the battery box 10.

[0046] Reference Figure 4The box body 11 may be a frame structure, such as a rectangular parallelepiped frame, and the protrusion 12 may be fixed to the bottom of the box body 11. The protrusion 12 protrudes from the bottom surface of the box body 11. The loader includes a frame 50, and the bottom surface of the box body 11 is the surface of the box body 11 for being placed on the frame 50. Along the width direction of the battery box 10, the width of the box body 11 may be equal to the length of the protrusion 12. Along the length direction of the battery box 10, the length of the box body 11 is greater than the width of the protrusion 12. The first bottom frame 13 is located at the bottom of the box body 11. The first bottom frame 13 may be a rectangular frame. The first bottom frame 13 includes four corners 19. The first bottom frame 13 may specifically be composed of two first frame bars 14 and two limiting bars 15. The two first frame bars 14 and the two limiting bars 15 are arranged to form a first rectangular space. In this case, the four corners 19 are the four corners of the first rectangular space. A plurality of positioning grooves 121 may be provided. The cross section of the positioning groove 121 can be circular or square, that is, the positioning groove 121 can be a circular groove or a square groove.

[0047] Reference Figure 6 , the first battery base 20 can be fastened to the frame 50, such as the first battery base 20 can be welded to the frame 50, or can be screwed to the frame 50. The secondary positioning pin 21 can be a round pin or a square pin, and the secondary positioning pin 21 is used to cooperate with the positioning groove 121 and to be inserted into the positioning groove 121. When the positioning groove 121 is set to multiple, the secondary positioning pin 21 is also set to multiple, and the positioning groove 121 corresponds to the secondary positioning pin 21 one by one. Along the height direction of the battery box 10, the groove depth of the positioning groove 121 is greater than or equal to the height of the secondary positioning pin 21. The height direction of the secondary positioning pin 21 is consistent with the height direction of the battery box 10. The cooperation between the secondary positioning pin 21 and the positioning groove 121 is used for horizontal limitation of the battery box 10, that is, limitation of the length direction and width direction of the battery box 10.

[0048] Reference Figure 6 The first battery base 20 and the second battery base 30 are used together to install the battery box 10, thereby realizing the installation of the battery box 10 and the loader. The second battery base 30 can be fastened to the frame 50, such as the second battery base 30 can be welded to the frame 50 or screwed to the frame 50. Figure 8 , along the height direction of the battery box 10, the second battery base 30 is higher than the first battery base 20, that is, the second battery base 30 is located above the first battery base 20. Figure 3 The box body 11 is located above the first battery base 20 and the second battery base 30 , and the protrusion 12 is located between the two second battery bases 30 .

[0049] The length direction of the first battery base 20 is consistent with the length direction of the battery box 10, and the two second battery bases 30 are respectively located on both sides of the length direction of the first battery base 20. It should be noted that the first battery base 20 and the second battery base 30 can have no connection relationship. The first limiting part 31 can be fixed on the second battery base 30, and the two first limiting parts 31 on the second battery base 30 are respectively located at both ends of the length direction of the second battery base 30, and the length direction of the second battery base 30 is consistent with the width direction of the battery box 10. The four first limiting parts 31 correspond to the four corners 19 one by one. The cooperation of the first limiting part 31 and the corner 19 is used for horizontal limiting of the battery box 10, and the first limiting part 31 is specifically used for being inserted into the four corners of the first rectangular space. In the height direction of the battery box 10, the height of the first limiting part 31 is greater than the height of the second positioning pin 21. The first limiting part 31 and the limiting strip 13 are used for coarse positioning of the battery box 10, and the positioning accuracy of the coarse positioning can be 5mm. The second positioning pin 21 and the positioning groove 121 are used for fine positioning of the battery box 10, and the positioning accuracy of the fine positioning can be 0.5mm.

[0050] In the embodiment of the application, the height of the first limiting part 31 is greater than the height of the second positioning pin 21, so that when the battery box 10 is installed, the corner on the battery box 10 is first matched with the first limiting part 31 to perform first-stage positioning, and then the positioning groove on the battery box 10 is matched with the second positioning pin 21 to perform second-stage positioning. That is, in the embodiment of the application, the split setting of the first battery base 20 and the second battery base 30 can realize two-stage positioning of the battery box 10, thereby ensuring the positioning accuracy when the battery box 10 is installed and reducing the deviation of the installation position of the battery box 10. In addition, in the embodiment of the application, the split setting of the first battery base 20 and the second battery base 30 can adapt to the structure of the loader and avoid the limitation of the arrangement of the positioning structure due to the insufficient space of the loader. In addition, in the embodiment of the application, the deviation of the installation position of the battery box 10 is small, so that the pressing part 32 can be accurately pressed on the locking block 18 when the battery box 10 is locked, that is, the smooth locking of the battery box 10 is ensured, and the locking of the battery box 10 is not affected.

[0051] The bottom of the box body 11 is also provided with a locking block 18, and the second battery base 30 is provided with a locking mechanism. The locking mechanism includes a driving assembly and a pressing part 32, and the driving assembly is used to drive the movement of the pressing part 32. The battery box 10 has a locked state and an unlocked state. When the battery box 10 is in the locked state, the pressing part 32 is pressed on the locking block 18. When the battery box 10 is in the unlocked state, the pressing part 32 is located on one side of the width direction of the locking block 18.

[0052] Specifically, the locking block 18 corresponds to the locking mechanism, and the locking mechanism is used to lock the battery box 10. Figure 1The locking block 18 can be fastened to the first bottom frame 13. For example, the locking block 18 can be fastened to the first bottom frame 13 by bolts or welded to the first bottom frame 13. When the battery box 10 is in the locked state, the movement of the battery box 10 along the height direction of the battery box 10 is restricted. When the battery box 10 is in the locked state, the battery box 10 can move along the height direction of the battery box 10 so that the battery box 10 can be lifted off the loader frame 50.

[0053] When the battery box 10 is installed, the battery box 10 is first placed on the vehicle frame 50 by hoisting, with the cooperation of the corner 19 and the first-level limiting portion 31, and the cooperation of the positioning groove 121 and the second-level positioning pin 21. Then, the driving assembly drives the pressing portion 32 to move so that the pressing portion 32 is pressed on the locking block 18 to limit the movement of the battery box 10 in the height direction of the battery box 10, so that the battery box 10 is in a locked state; thereafter, when the battery box 10 needs to be lifted off the loader, the driving assembly drives the pressing portion 32 to move so that the pressing portion 32 moves to one side in the width direction of the locking block 18, so that the battery box 10 is in a locked state. At this time, the battery box 10 can move in the height direction of the battery box 10. In this embodiment of the present invention, by setting the locking mechanism and the locking block 18, the battery box 10 can be locked in the vertical direction to ensure that the battery box 10 is tightly connected to the second battery base 30 when the loader is working.

[0054] The first bottom frame 13 is provided with two locking block groups spaced apart along the length direction of the box body 11. The locking block groups include two locking blocks 18 arranged opposite to each other along the width direction of the box body 11. Each second battery base 20 is provided with two locking mechanisms, and the two locking mechanisms on the second battery base 20 correspond to the locking block groups.

[0055] Specifically, refer to Figure 4 , the two locking blocks 18 included in the locking block group can be symmetrically arranged, and two locking block groups are provided on the first bottom frame 13, that is, four locking blocks 18 are provided on the first bottom frame 13. The locking block 18 is specifically located on the side of the corner 19 close to the protrusion 12. Each second battery base 20 is provided with two locking mechanisms, and the vehicle-mounted battery installation assembly includes a total of four locking mechanisms. The two locking mechanisms on the second battery base 20 are respectively located at both ends of the length direction of the second battery base 30. The two locking mechanisms on the second battery base 20 respectively correspond to the two locking blocks 18 included in the locking block group. In an embodiment of the present invention, by providing two locking block groups and four locking mechanisms, the locking performance of the battery box 10 when locked in the vertical direction can be guaranteed.

[0056] Reference Figure 9The driving assembly includes a cylinder 33 and a connecting plate 34. The locking mechanism also includes a first base 35 and a second base 36. The cylinder 33 includes a shell and an output shaft. The shell is hinged on the first base 35. The first base 35 is fastened to the second battery base 30. The output shaft is hinged to the connecting plate 34. The pressing part 32 is fastened to the connecting plate 34. The connecting plate 34 is hinged on the second base 36. The second base 36 is fastened to the second battery base 30.

[0057] Specifically, the connecting plate 34 is vertically arranged, with two pressing portions 32 disposed on either side of the connecting plate 34 along the width of the second battery base 30. The pressing portions 32 may be cylindrical in shape, with a circular cross-section. The axis of the pressing portion 32 aligns with the width of the second battery base 30, and the cross-section is perpendicular to the width of the second battery base 30. The pressing portion 32 is rotatably connected to the connecting plate 34, rotating about its axis.

[0058] The locking block 18 includes a mating portion 182, which is used to mate with the end of the lower half of the pressing portion 32 that is away from the cylinder 33. The locking block 18 also includes an avoidance portion 183, which is fixed to the side of the mating portion 182 that is away from the first frame bar 14. The pressing portion 32 includes a pressing state and a storage state. When the pressing portion 32 is in the pressing state, the battery box 10 is in a locked state; when the pressing portion 32 is in the storage state, the pressing portion 32 is located on the side of the locking block 18 that is away from the first frame bar 14, and the battery box 10 is in an unfastened state. The avoidance portion 183 is used to enable the pressing portion 32 to move smoothly from the pressing state to the storage state, and from the storage state to the pressing state. The locking block 18 also includes an avoidance groove 181 for avoiding the connecting plate 34.

[0059] When the battery box 10 is in the locked state, the pressing portion 32 is in the Figure 9 In the clamping state shown, at this time, the end of the lower half of the clamping part 32 facing away from the cylinder 33 is pressed against the matching part 182, the end of the lower half of the connecting plate 34 facing away from the cylinder 33 is located in the avoidance groove 181, and the output shaft extends. When the battery box 10 needs to be lifted off the loader, first, the cylinder 33 works to retract the output shaft, driving the connecting plate 34 to rotate counterclockwise. During this process, the rotation of the connecting part 34 will drive the end of the lower half of the clamping part 32 facing away from the cylinder 33 to disengage from the matching part 182 and move along the avoidance part 183 to the storage state. At this time, the clamping part 32 is located on the side of the locking block 18 facing away from the first frame bar 14, and the end of the lower half of the connecting plate 34 facing away from the cylinder 33 is not located in the avoidance groove 181, so that the battery box 10 is in the unlocked state. In this embodiment of the present invention, the arrangement of the cylinder 33 and the connecting plate 34 can realize the driving of the movement of the clamping part 32.

[0060] The first bottom frame includes two first frame bars 14 and two limit bars 15. The two first frame bars 14 are arranged opposite to each other along the width direction of the box body 11. The two limit bars 15 are arranged between the two first frame bars 14. The two limit bars 15 are spaced apart along the length direction of the box body 11. The first-level limit portion 31 includes a first limit plate 311 and a second limit plate 312 connected to each other. The first limit plate 311 is used to limit the displacement of the limit bar 15, and the second limit plate 312 is used to limit the displacement of the first frame bar 14.

[0061] Specifically, refer to Figure 4 , the extension direction of the first frame bar 14 is consistent with the length direction of the box body 11, and the extension direction of the limiting bar 15 is consistent with the width direction of the box body 11. Along the length direction of the box body 11, the length of the first frame bar 14 can be equal to the length of the box body 11. The limiting bar 15 can be welded between the two first frame bars 14, such as one end of the limiting bar 15 in the length direction is welded to the inner side surface of one of the first frame bars 14, and the other end of the limiting bar 15 in the length direction is welded to the inner side surface of the other first frame bar 14. The inner side surface of the first frame bar 14 is the surface of the first frame bar 14 close to the limiting bar 15. Refer to Figure 6 The first-level limiting portion 31 includes a first limiting plate 311 and a second limiting plate 312 connected to each other. The first limiting plate 311 and the second limiting plate 312 can be integrally formed.

[0062] The battery box 10 is installed behind the loader via the first battery base 20 and the second battery base 30. The first limiting plate 311 is located on the inner side of the limiting bar 15, and the second limiting plate 312 is located on the inner side of the first frame bar 14. The inner side of the limiting bar 15 is the side of the limiting bar 15 close to the protrusion 12, and the inner side of the first frame bar 14 is the side of the first frame bar 14 close to the limiting bar 15. The locking block 18 can be welded to the inner side of the first frame bar 14, in which case the primary limiting portion 31 is located between the locking block 18 and the limiting bar 15. In this embodiment of the present invention, the first limiting plate 311 can be provided to limit the movement of the battery box 10 along its length, and the second limiting plate 312 can be provided to limit the movement of the battery box 10 along its width, thereby achieving horizontal limitation of the battery box 10.

[0063] The cross-sections of the secondary positioning pin 21 and the positioning groove 121 are both circular. The secondary positioning pin 21 includes a positioning portion 211 and a guide portion 212 fixed to the positioning portion 211. The positioning portion 211 is used to cooperate with the positioning groove 121; the guide portion 212 has a first end away from the positioning portion 211 and a second end close to the positioning portion 211. From the second end to the first end, the cross-sectional area of ​​the guide portion 212 gradually decreases. In the embodiment of the present invention, through the provision of the guide portion 212, when the battery box 10 is hoisted on the loader, under the guidance of the guide portion 212, the positioning groove 121 on the battery box 10 can slowly cooperate with the positioning portion 211, so that the battery box 10 reaches the installation position.

[0064] The vehicle-mounted battery mounting assembly provided by an embodiment of the present invention also includes a shock-absorbing rubber pad 40, two of which are provided.
