DETAILED DESCRIPTION

[0018] The specific embodiments of the present application are described in detail below, but it should be understood that the protection scope of the present application is not limited by the specific embodiments.

[0019] As Figures 1 to 6 ​​As shown, the new energy automobile battery mounting bottom plate structure and process provided by the embodiment of the application comprises a battery box 4, characterized in that it further comprises: A bearing mechanism 1 comprising a bearing plate 101 mounted on the automobile bottom plate; A moving mechanism 2 comprising two moving seats 201 symmetrically slidingly mounted on the bearing plate 101, and the bearing mechanism 1 is provided with an adjusting assembly 202 for driving the two moving seats 201 to move; A buckling mechanism 3 comprising a plurality of plug-in plates 301 rotatably mounted on the moving seats 201, and the moving seats 201 are provided with knob members 302, that is, the total number of knob members 302 is two, the knob members 302 act on the plurality of plug-in plates 301, and the battery box 4 is symmetrically provided with a plurality of plug-in grooves 303, when the knob members 302 are rotated, the plurality of plug-in plates 301 are synchronously moved to be inserted into the plurality of plug-in grooves 303; That is, in use, the distance between the two moving seats 201 can be adjusted according to the size of the battery box 4 first, and after the adjustment, the battery box 4 is moved to be attached to the bearing plate 101, at this time, the battery box 4 is located between the two moving seats 201, it should be noted that in the prior art, the battery box 4 is moved vertically upward by a lifting machine, and the automobile chassis is in a state of being lifted, the bearing plate 101 is mounted on the automobile bottom plate by bolts, when the battery box 4 is moved, at this time, the workers rotate the two knob members 302, the knob members 302 will make the plurality of plug-in plates 301 rotate when rotating, so that the plurality of plug-in plates 301 are respectively inserted into the plurality of plug-in grooves 303, as Figure 6 As shown, the plug-in plate 301 is arc-shaped, after the plug-in plate 301 is inserted into the plug-in groove 303, the plug-in plate 301 can be effectively prevented from moving in the plug-in groove 303, compared with the prior art, the distance between the two moving seats 201 can be adjusted according to the actual size of the battery box 4, and only by rotating the knob members 302 can the plurality of plug-in plates 301 be inserted into the corresponding plug-in grooves 303, which is more convenient in use and improves the applicability.

[0020] As Figure 1 , Figure 2 to and Figure 6As shown in the drawings, in some embodiments, the knob 302 comprises a threaded rod 3021 horizontally and rotatably mounted on the moving seat 201, a moving plate 3022 vertically slidably mounted on the moving seat 201, the moving plate 3022 threadedly sleeved on the threaded rod 3021, and a linkage 5 mounted between the moving plate 3022 and the plurality of insertion plates 301. When the moving plate 3022 moves vertically, the plurality of insertion plates 301 are driven to rotate synchronously by the linkage 5. Specifically, the threaded rod 3021 is provided with a regular hexagonal groove at the bottom end, facilitating the rotation of the threaded rod 3021 by the staff. When the threaded rod 3021 rotates, the threaded rod 3021 drives the moving plate 3022 threadedly sleeved thereon to move vertically. During the vertical movement of the moving plate 3022, the plurality of insertion plates 301 are driven to rotate simultaneously by the linkage 5, so as to realize the insertion of the plurality of insertion plates 301 into the corresponding insertion slots 303. The design of the threaded rod 3021 makes the moving plate 3022 not prone to accidental movement due to external vibration after moving, thereby avoiding the disengagement of the insertion plates 301 from the corresponding insertion slots 303 during the driving of the automobile.

[0021] As shown in the drawings, Figure 1 , Figure 2 and Figure 6 , in some embodiments, the linkage 5 comprises a hinged cylinder 501 hingedly mounted on the moving seat 201, a plug-in rod 502 slidably inserted into the free end of the hinged cylinder 501, and a connecting rod 503 hingedly connected to one end of the plug-in rod 502 and fixedly mounted on the insertion plate 301. The moving plate 3022 is coupled to the plurality of plug-in rods 502. When the moving plate 3022 moves, the plurality of plug-in rods 502 move along the length direction of the corresponding hinged cylinder 501, that is, when the moving plate 3022 moves, the plurality of plug-in rods 502 extend or retract along the length direction of the hinged cylinder 501. During the movement of the plug-in rod 502, the connecting rod 503 hingedly connected to the plug-in rod 502 moves. Since the connecting rod 503 is fixedly mounted on the insertion plate 301, the hinged cylinder 501 self-adapts to rotate when the plug-in rod 502 moves in the hinged cylinder 501, thereby forcing the insertion plate 301 to rotate arcuately by the plug-in rod 502, so as to realize the insertion of the insertion plate 301 into the corresponding insertion slot 303.

[0022] As shown in the drawings, Figure 1 and Figure 6As shown in the drawings, in some embodiments, the hinge cylinder 501 is provided with a through slot 504 along the length direction thereof, the moving plate 3022 is provided with a plurality of driving frame plates 506, one side of the insertion rod 502 is provided with a columnar rod 507 passing through the through slot 504, and the plurality of columnar rods 507 are slidingly tangent to the plurality of driving frame plates 506. Specifically, the driving frame plates 506 are formed with horizontal sliding cavities, and the columnar rods 507 are slidingly tangent to the sliding cavities. That is, when the moving plate 3022 moves, the moving plate 3022 moves to drive the plurality of driving frame plates 506 to move. Because the columnar rods 507 are slidingly tangent to the driving frame plates 506, the moving plate 3022 moves vertically to force the columnar rods 507 to move vertically. At this time, the columnar rods 507 move horizontally in the driving frame plates 506 to ensure that the plurality of insertion rods 502 synchronously extend or retract, and ensure that the plurality of insertion plates 301 can be simultaneously inserted into the corresponding insertion grooves 303.

[0023] As shown in the drawings, Figure 1 , Figure 2 and Figure 4 , in some embodiments, the adjusting assembly 202 comprises a driving gear 2021 rotatably installed on the bearing plate 101, two driving racks 2022 are installed on the two moving seats 201 and engaged with the driving gear 2021, the two driving racks 2022 are distributed in an up-down manner and parallel to each other, and a driving screw 2023 is horizontally rotatably installed on the bearing plate 101. One of the moving seats 201 is threadedly sleeved on the driving screw 2023, and the driving screw 2023 only needs to drive one of the moving seats 201 to move when the driving screw 2023 rotates. At this time, the moving seat 201 moves to drive the driving rack 2022 installed thereon to move. Because the two driving racks 2022 are engaged with the driving gear 2021, at this time, the two moving seats 201 synchronously move close to or away from each other to ensure that the subsequently installed battery box 4 is located at the middle position of the bearing plate 101, and the uniformity of weight distribution is ensured. In addition, because the driving screw 2023 drives one of the moving seats 201 to move, the length of the driving screw 2023 can be designed to be shorter, which can avoid the insufficient rigidity caused by the excessive length of the driving screw 2023.

[0024] As shown in the drawings, Figure 1 , Figure 2 and Figure 4As shown in the drawings, in some embodiments, the mobile seat 201 is provided with a support assembly 6, which is in contact with the bottom surface of the battery box 4 after the battery box 4 is installed on the bearing plate 101. The design of the support assembly 6 plays a role in protection and auxiliary support. When the plug-in plate 301 is deformed due to aging after long-term use, the support assembly 6 can assist the plug-in plate 301 at this time, thereby distributing the pressure received by the plug-in plate 301, improving the stability after overall installation, and indirectly improving the effect after the subsequent installation of the battery box 4.

[0025] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in some embodiments, the support assembly 6 includes a moving piece 601 installed on the mobile seat 201, and a support plate 602 is elastically and horizontally slidably installed on the moving piece 601. The moving piece 601 moves to make the support plate 602 separate from the bottom of the battery box 4. In order to avoid the support plate 602 interfering with the installation of the battery box 4, the position of the support plate 602 is changed by the moving piece 601 when the battery box 4 is installed. In the subsequent disassembly and installation of the battery box 4, the support plate 602 can effectively avoid hard contact with the battery box 4, and the use is more convenient.

[0026] As shown in the drawings, Figures 1 to 3As shown, in some embodiments, the moving piece 601 comprises a mounting cylinder 6011 hinged on the moving seat 201, one end of the support plate 602 is horizontally inserted on the mounting cylinder 6011, a connecting spring 6012 is installed between the mounting cylinder 6011 and the support plate 602, a sliding seat 6013 is vertically and slidingly installed on the moving seat 201, a hinge rod 6014 is hinged between the sliding seat 6013 and the mounting cylinder 6011, a limiting insertion plate 6015 is elastically and obliquely slidingly inserted on the sliding seat 6013, preferably, a spring is installed between the sliding seat 6013 and the limiting insertion plate 6015, two limiting inclined grooves 6016 are obliquely arranged on the moving seat 201, and the bottom end of the limiting insertion plate 6015 is used for insertion into the limiting inclined groove 6016. The oblique design of the limiting insertion plate 6015 cooperates with the spring, which can effectively prevent the limiting insertion plate 6015 from being separated from the corresponding limiting inclined groove 6016 during the driving of the automobile, and prevent the mounting cylinder 6011 from accidentally rotating. When the battery box 4 needs to be disassembled, the sliding seat 6013 is only needed to be moved, the sliding seat 6013 moves to drive the limiting insertion plate 6015 to move, until the limiting insertion plate 6015 is directed to the other limiting inclined groove 6016. The sliding seat 6013 moves to drive the hinge rod 6014 to move, because one end of the hinge rod 6014 is hinged on the mounting cylinder 6011, the sliding seat 6013 moves through the hinge rod 6014 to drive the mounting cylinder 6011 to rotate, thereby making the limiting insertion plate 6015 rotate away from the battery box 4, and then the limiting insertion plate 6015 is inserted into the corresponding limiting inclined groove 6016.

[0027] As shown in the drawings, Figures 1 to 3 When the battery box 4 is installed, the limiting insertion plate 6015 does not affect the installation, but the mounting cylinder 6011 does not need to be rotated, and the free end of the limiting insertion plate 6015 is configured with a forcing inclined surface 6017 along the edge at the bottom. When the battery box 4 moves upward, the top of the battery box 4 will contact the forcing inclined surface 6017 of the limiting insertion plate 6015, so that the limiting insertion plate 6015 is retracted into the corresponding mounting cylinder 6011, thereby eliminating the need to additionally rotate the mounting cylinder 6011, and the use is more convenient.

[0028] As shown in the drawings, Figures 1 to 6 A new energy automobile battery mounting bottom plate process, comprising the new energy automobile battery mounting bottom plate structure, comprising the following steps: S1: operating the adjusting assembly 202 to drive the two moving seats 201 to move towards or away from each other on the bearing plate 101 to adjust the distance between the two moving seats 201, so that the position of the insertion plate 301 thereon is adapted to the position of the insertion slot 303 on the side of the battery box 4 to be installed; S2: Place the battery box 4 on the bearing plate 101, and make sure that the plurality of insertion slots 303 on both sides of the battery box 4 are respectively aligned with the plurality of insertion plates 301 on the two moving seats 201; S3: Rotate the knob 302 to drive the plurality of insertion plates 301 to rotate synchronously, so that each insertion plate 301 is inserted into the corresponding insertion slot 303, thereby locking and fixing the battery box 4 on the bearing plate 101.

[0029] The above disclosed are only several specific embodiments of the present application, but the embodiments of the present application are not limited to this, any changes that can be thought of by any person skilled in the art shall fall within the protection scope of the present application.
