Description

Technical Field

[0001] The utility model relates to the technical field of electric balancing vehicles, and in particular to a battery fixing structure of an electric balancing vehicle. Background Art

[0002] Electric balancing car, also known as somatosensory car, thinking car, camera car, etc. There are mainly two types of electric balancing car on the market: unicycle and two-wheeled. Its operating principle is mainly based on a basic principle called "dynamic stability". It uses the gyroscope and acceleration sensor inside the car body to detect changes in the body posture, and uses the servo control system to accurately drive the motor to make corresponding adjustments to maintain the balance of the system. Common electric balancing cars are mainly divided into electric balancing cars controlled by joysticks or electric balancing twisting cars formed by two balancing car bodies pivoted together. Due to their own volume limitations, existing electric balancing cars generally have poor endurance. This is mainly due to the limited space for batteries in the pedal seat of the electric balancing car. When it is necessary to travel a long distance, the existing electric balancing car will appear to be less practical. In addition, since the battery of the electric balancing car needs to be charged for a long time, and the entire battery is installed inside the pedal seat, even if you carry a spare battery with you, you need to disassemble the entire pedal seat to replace the battery, which causes great inconvenience to the use of the electric balancing car.

[0003] To this end, there is an improved technology on the market that proposes an electric balance vehicle backup battery installation structure, including an electric balance vehicle body, a first groove is opened at the bottom of the electric balance vehicle body, a baffle is slidably arranged in the first groove, and second grooves are opened on both sides of one side of the electric balance vehicle body, and the two second grooves are arranged at intervals, and the two second grooves are connected to the first groove, and fixing mechanisms are installed in the two second grooves, and the two fixing mechanisms fix the baffle;

[0004] However, the above-mentioned improved technology has obvious disadvantages in use. The movable column used to limit the baffle is driven by a connecting rod, and the connecting rod is located outside the electric balance vehicle body. It is easy to be accidentally touched and cause the movable column to move up. When the movable column is not limited, the baffle is easy to slide out. If it is not discovered in time, it is easy to cause an accident. Therefore, it is necessary to further improve the battery fixing structure of the electric balance vehicle. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figures 1 to 8 The utility model provides a battery fixing structure for an electric balancing vehicle: comprising a battery and a housing 1, wherein the lower wall of the housing 1 is provided with a sliding cavity 8 penetrating the front wall of the housing 1, and the upper wall of the inner side wall of the sliding cavity 8 is provided with a battery compartment 9 recessed in the upper wall of the inner side wall, and the battery is arranged inside the battery compartment 9, and the interior of the battery compartment 9 is consistent with the prior art, and is provided with a protective device for squeezing and protecting the battery from the side, so as to prevent the battery from being bumped;

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 8As shown, in order to connect the cover plate 2 with the sliding cavity 8, the inner wall of the sliding cavity 8 is slidably connected with the cover plate 2 for closing the battery compartment 9 through a sliding structure, and the sliding structure includes two groups of slide bars 7 and slide grooves 10. The two groups of slide bars 7 are respectively fixedly connected to the left and right side walls of the cover plate 2 and are both located near the upper wall. The two groups of slide grooves 10 are respectively arranged on the inner left wall and the inner right wall of the sliding cavity 8 and are both located near the inner upper wall of the sliding cavity 8. The two groups of slide bars 7 are slidably connected to the inner walls of the two groups of slide grooves 10 on the sides away from the cover plate 2. Through the sliding structure, the cover plate 2 can slide back and forth in the sliding cavity 8, but will not fall out from under the sliding cavity 8.

[0033] like Figure 8 As shown, in order to protect the battery after the cover plate 2 closes the battery compartment 9, a buffer structure for buffering is provided on the side of the cover plate 2 facing the battery compartment 9, and the buffer structure is a rubber pad 20. The upper wall of the cover plate 2 is provided with a sink recessed in the upper wall, and the rubber pad 20 is fixedly connected to the inner side wall of the sink and the upper surface of the rubber pad 20 is flush with the upper surface of the cover plate 2. After the cover plate 2 is closed, the battery is protected by the rubber pad 20.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 6 as well as Figure 7As shown, in order to lock the position of the cover plate 2, an installation cavity 12 recessed in the front wall is provided on the front wall of the shell 1 and located on the left side of the sliding cavity 8, a pin box 3 is fixedly connected to the inner wall of the installation cavity 12, a cavity is provided inside the pin box 3, a rectangular opening 4 which is connected to the inside and outside of the cavity is provided on the front wall of the pin box 3, a square pin 5 is slidably connected to the inner wall of the cavity, a shifting hole 6 for inserting a finger and shifting the square pin 5 is provided on the front wall of the square pin 5, a positioning structure for positioning the longitudinal position of the cover plate 2 is provided between the end of the square pin 5 facing the cover plate 2 and the cover plate 2, the positioning structure includes a spring pin 19, an anti-drop limit hole 15 and a locking limit hole 16, the spring pin 19 is fixedly connected to the end of the square pin 5 facing the cover plate 2, a left-right through-hole 11 is provided between the installation cavity 12 and the sliding cavity 8, and the end of the spring pin 19 away from the square pin 5 passes through the right wall of the pin box 3 and is connected to the left and right sides of the pin box 3. The inner wall of the yield hole 11 is slidably connected, and the anti-drop limit hole 15 and the locking limit hole 16 are fixedly connected to the side of the cover plate 2 facing the elastic pin 19, and the anti-drop limit hole 15 and the locking limit hole 16 are respectively close to the rear wall and the front wall of the cover plate 2, and the outer diameter of the elastic pin 19 is adapted to the inner diameter of the anti-drop limit hole 15 and the locking limit hole 16. When the cover plate 2 is fully inserted into the sliding cavity 8, the elastic pin 19 is inserted into the locking limit hole 16, so that the cover plate 2 cannot continue to move forward and backward, and the battery is fixed when the electric balance car is used. When the battery needs to be replaced, in order to avoid the cover plate 2 completely coming out of the sliding cavity 8, causing difficulties in reassembly or corner bumps, the cover plate 2 is pulled out toward the front side of the sliding cavity 8 until it is about to be pulled out, and the elastic pin 19 elastically enters the anti-drop limit hole 15 through the second spring 18. At this time, the cover plate 2 cannot continue to be pulled outward, which plays a role in preventing it from falling;

[0035] like Figure 7 As shown, in order to generate an extrusion force on the elastic pin 19, a first elastic structure for maintaining the stability of the positioning structure is provided between the end of the square pin 5 away from the cover plate 2 and the inner wall of the cavity, and the first elastic structure includes a sliding column 17 and a second spring 18. The sliding column 17 is fixedly connected to the inner left wall of the pin box 3, and the end of the sliding column 17 facing the square pin 5 passes through the left end of the square pin 5 and is slidably connected thereto. The second spring 18 is sleeved on the outer wall of the sliding column 17 and is located between the left end of the square pin 5 and the inner left wall of the pin box 3. Under the elastic extrusion of the second spring 18, the elastic pin 19 remains stable without the action of external force;

[0036] like Figure 3 , Figure 5As shown, in order to simplify the operation when it is necessary to open the cover 2, a second elastic structure is arranged between the cover 2 and the inner rear wall of the sliding cavity 8, and the second elastic structure includes three groups of first springs 14. The inner rear wall of the sliding cavity 8 is provided with three groups of mounting holes 13 from left to right, and the three groups of first springs 14 are respectively arranged on the inner walls of the three groups of mounting holes 13. The front ends of the three groups of first springs 14 extend toward the inside of the sliding cavity 8. When a finger is inserted into the dial hole 6, the square pin 5 is moved toward the side away from the cover 2, and the spring pin 19 is disengaged from the locking limit hole 16, the cover 2 will automatically pop forward a certain distance by the elastic force of the three groups of first springs 14, so that the cover can be opened with one hand.

[0037] Working principle: Through the sliding structure, the cover plate 2 can slide back and forth in the sliding cavity 8, but will not fall out from under the sliding cavity 8. After the cover plate 2 is closed, the battery is protected by the rubber pad 20 on its lower surface. The outer diameter of the spring pin 19 is adapted to the inner diameter of the anti-drop limit hole 15 and the locking limit hole 16. When the cover plate 2 is fully inserted into the sliding cavity 8, the spring pin 19 is inserted into the locking limit hole 16, so that the cover plate 2 cannot continue to move forward and backward, and the battery is fixed when the electric balance car is in use. When the battery needs to be replaced, in order to avoid the cover plate 2 completely falling out of the sliding cavity 8, causing difficulty in reassembly or corner knocks When the cover 2 is pulled toward the front side of the sliding cavity 8 and is about to be pulled out, the spring pin 19 elastically enters the anti-drop limit hole 15 through the second spring 18. At this time, the cover 2 cannot be pulled out further, which plays an anti-drop effect. The elastic squeezing of the second spring 18 keeps the spring pin 19 stable without the action of external force. When a finger is inserted into the dial hole 6, the square pin 5 is moved toward the side away from the cover 2, and the spring pin 19 is disengaged from the locking limit hole 16, the cover 2 will automatically pop forward a certain distance through the elastic force of the three groups of first springs 14, so that the cover can be opened with one hand.
