Technical Field
[0001] This utility model relates to the field of battery box technology, and in particular to a battery box anti-fall structure. Background Technology
[0002] In the design of electric vehicles, electric bicycles and other vehicles, the battery box is a key component for storing and providing power, and its stability and safety are of paramount importance. Traditional battery box installation methods mostly use bolt fixing or direct insertion into the frame tube. However, this method is not convenient when the battery box needs to be frequently disassembled or replaced. In order to improve the user experience, modern vehicle design tends to adopt a simpler battery box locking structure, which allows users to easily install or remove the battery box.
[0003] However, this simple locking structure also brings new challenges. When the battery box is in the unlocked state, without additional limiting measures, the battery box may fall directly off the frame tube, which can easily damage the battery box. Therefore, it is particularly important to design a fall protection structure that can effectively prevent the battery box from falling off in the unlocked state.
[0004] Existing battery boxes generally lack fall protection structures, and those that do have complex fall protection structures that are not ideal in certain situations. For example, some structures have too many mechanical parts, increasing the failure rate; others may be inconvenient for users to operate due to unreasonable design, making it difficult to remove or install the battery box. Therefore, the market urgently needs a battery box fall protection structure that is simple in structure, low in cost, has a significant fall protection effect, and is easy for users to operate.
[0005] Based on this, the applicant proposed a battery box anti-fall structure to solve the above technical problems. Utility Model Content

[0035] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1:
[0036] like Figures 1 to 7 As shown, the present invention discloses a battery box anti-fall structure, including a rocker plate 1 movably disposed at one end of the battery box body. A return spring 2 is disposed between the rocker plate 1 and the battery box body. A groove 11 is disposed on the side of the rocker plate 1 facing away from the battery box body. A spring pin 3 is disposed on the frame tube opposite to the rocker plate 1. The spring pin 3 is engaged with the groove 11. A limiting protrusion 4 is disposed on the battery box body below the rocker plate 1. A locking tongue washer 6 is also disposed on the limiting protrusion 4. When the battery box body is unlocked, the spring pin 3 and the limiting protrusion 4 abut against each other to limit the battery box body, thereby preventing the battery box body from directly detaching from the frame tube.
[0037] The anti-fall structure designed in this utility model achieves effective limiting of the battery box body in the unlocked state through the ingenious cooperation of components such as rocker plate, return spring, groove, spring pin and limiting protrusion. Even if it is accidentally touched, the battery box body will not easily fall off. At the same time, when the battery box body is inserted, the rocker plate will not hit and scratch the frame tube, avoiding the paint of the frame tube being scratched off.
[0038] A pressing part 12 is provided on the rocker 1 outside the groove 11. The pressing part 12 is provided with a plurality of anti-slip protrusions 121. The reset spring 2 is provided on the back side of the pressing part 12. After unlocking, when the battery box body is rotated open to the point where the spring pin 3 abuts against the limiting protrusion 4, the pressing part 12 is exposed. Pressing the pressing part 12 causes it to rotate, and the groove 11 forces the spring pin 3 to retract. When the spring pin 3 retracts to the point of disengaging from the limiting protrusion 4, the limiting of the battery box body is released.
[0039] The pressing part design in this utility model allows users to unlock the battery box body simply by pressing it when they need to remove it. The operation is simple and quick, and there is little chance of inconvenience.
[0040] The rocker arm 1 has symmetrically arranged semi-circular protrusions 13 on the center of the side facing the battery box body. The battery box body has a corresponding mating groove 5. The semi-circular protrusions 13 are adapted to the mating groove 5. The rocker arm 1 has a through hole 14 between the two semi-circular protrusions 13. The mating groove 5 has a corresponding mounting post 7. The rocker arm 1 is fitted into the mounting post 7 through the through hole 14. The rocker arm 1 and the mounting post 7 are in clearance fit. The rocker arm 1 is prevented from detaching from the mounting post 7 by setting a screw 8 on the mounting post 7. A washer is also set between the screw 8 and the mounting post 7. The size of the washer is larger than the cross-sectional size of the through hole 14.
[0041] Compared to existing anti-fall structures with too many mechanical parts, the structure of this utility model is simpler, reduces failure points, and improves overall reliability and durability. Due to the simplified structural design, the battery box anti-fall structure of this utility model has a greater advantage in production cost, which helps to reduce the overall cost of electric vehicles, electric bicycles and other transportation vehicles.
[0042] In other embodiments, when the head cross-sectional dimension of the screw 8 is larger than the cross-sectional dimension of the through hole 14, a washer may not be provided.
[0043] In other embodiments, the rocker 1 can be rotatably connected to the battery box body via a pivot.
[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
