Description

Technical Field

[0001] This utility model relates to the technical field of pedal-type electric vehicle accessories, and in particular to a battery mounting structure and a pedal-type electric vehicle. Background Technology

[0002] The foot pedal of a pedal-type electric vehicle has a battery mounting slot inside. The battery is installed in the battery mounting slot of the foot pedal. The bottom of the battery mounting slot is generally flat. The battery fits in the battery mounting slot. After the battery is installed, a layer of foam material is compressed and filled around the battery and on its top surface. The foam material can achieve a good seal between the battery and the mounting slot. After the battery is installed, a cover plate is also installed on the top of the battery mounting slot to limit the vertical movement of the battery.

[0003] However, in actual use, the bottom of the traditional battery mounting slot is a flat structure, and the contact rigidity between the battery and the bottom of the battery mounting slot is relatively large. In addition, the foam material is only filled around the battery and on the upper surface. The battery is relatively heavy, and the foam material has limited contribution to the cushioning of bottom vibration. When the motor vibrates or the vehicle bumps, it is difficult to prevent the battery from shifting to a certain extent in the vertical direction by relying solely on the longitudinal restraint of the cover plate. This causes the battery to rub and collide with the wall of the battery mounting slot, thereby generating vibration. This vibration is directly transmitted to the bottom of the battery mounting slot and then to the pedal, affecting the rider's comfort. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional battery mounting slot structures cannot effectively absorb and mitigate the vibrations generated when the battery is moved, which affects the rider's comfort.

[0005] To solve the above-mentioned technical problems, this utility model provides a battery mounting structure, including a battery mounting cavity with a bottom wall, and a battery. The bottom wall has at least two upwardly protruding damping parts, and a downwardly extending connecting part is provided between each pair of adjacent damping parts. Each connecting part is fixedly connected to the adjacent damping part and the connection parts are smoothly transitioned.

[0006] Each vibration damping part forms a first vibration damping space at its lower part, and each connecting part forms a second vibration damping space at its upper part;

[0007] The battery is placed on the vibration damping part, and / or the battery is placed on the upper side of each vibration damping part and each connecting part;

[0008] Each vibration damping part and / or each connecting part is subjected to elastic deformation by external force, compressing the first vibration damping space and / or the second vibration damping space.

[0009] Preferably, there are two strip-shaped vibration damping parts, which are arranged in parallel and spaced apart. The connecting part is located at the interval between the two vibration damping parts. Openings that penetrate the bottom wall are reserved at both ends of the vibration damping part in the length direction and at both ends of the connecting part in the length direction.

[0010] Preferably, each vibration damping part has a flat surface at its top.

[0011] Preferably, the battery mounting structure further includes an elastic strap, with both ends of the elastic strap fixed to the side wall of the battery mounting cavity, and the elastic strap is used to elastically fix the battery.

[0012] Preferably, the battery mounting structure also includes a cover plate, which covers the top of the battery mounting cavity. A gap is left between the cover plate and the elastic strap, forming a third vibration damping space, which provides space for the elastic strap to deform elastically.

[0013] Preferably, the bottom of each connecting part extends to the lower side of the bottom wall in the vertical direction.

[0014] Preferably, connecting ears are fixed on both sides of the battery mounting cavity, and the two ends of the elastic strap are tied to the connecting ears.

[0015] Preferably, the connecting ear is welded to the side wall of the battery mounting cavity.

[0016] Preferably, the surface of the top plane of each vibration damping part is provided with anti-slip texture.

[0017] This utility model also provides a pedal-type electric vehicle, including a foot pedal, and the aforementioned battery mounting structure is provided inside the foot pedal.

[0018] Compared with the prior art, the battery mounting structure and pedal-type electric vehicle of this utility model embodiment have the following advantages:

[0019] This utility model provides a battery mounting structure and a pedal-type electric vehicle. By providing at least two upwardly protruding damping portions on the bottom wall, and a downwardly extending connecting portion between each pair of adjacent damping portions, each connecting portion is fixedly connected to and smoothly transitions with the adjacent damping portions. A first damping space is formed at the lower part of each damping portion, and a second damping space is formed at the upper part of each connecting portion. A battery is placed on the damping portions, and / or simultaneously placed on the upper side of each damping portion and each connecting portion. Each damping portion and / or each connecting portion is elastically deformed by external force, compressing the first damping space and / or the second damping space, effectively absorbing and mitigating battery vibration and improving rider comfort.

Detailed Implementation

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples.

[0028] like Figures 1 to 5 As shown, this utility model embodiment provides a battery mounting structure, including a battery mounting cavity 1 with a bottom wall 2. The bottom wall 2 is provided with two upwardly protruding vibration damping parts 3, which are arranged in parallel and spaced apart. A connecting part 4 is provided at the interval between the two vibration damping parts 3. The connecting part 4 is fixedly connected to the adjacent vibration damping part 3 and smoothly transitions. By providing vibration damping parts 3 and connecting parts 4 on the bottom wall 2, the rigidity of the bottom wall 2 in contact with the battery 7 is reduced.

[0029] Specifically, the lower part of the two damping parts 3 forms a first damping space 5, the upper part of the connecting part 4 forms a second damping space 6, the battery 7 is placed in the battery mounting cavity 1, and the bottom of the battery 7 is placed on the upper side of each damping part 3 and the connecting part 4.

[0030] Specifically, each damping part 3 and the connecting part 4 are made of elastic material. When each damping part 3 is elastically deformed by external force, each damping part 3 squeezes the first damping space 5. When the connecting part 4 is elastically deformed by external force, the connecting part 4 squeezes the second damping space 6.

[0031] When the motor vibrates or the vehicle bumps, the battery 7 is displaced to a certain extent by external forces. The damping sections 3 and connecting sections 4 located below the battery 7 can undergo elastic deformation, absorbing and dispersing the vibration energy of the battery 7. The first damping space 5 formed at the bottom of the damping section 3 and the second damping space 6 formed at the top of the connecting section 4 provide space for the elastic deformation of the damping sections 3 and connecting sections 4, thereby enhancing the damping effect. Through effective damping, the vibration energy of the battery 7 under external forces is significantly reduced, preventing vibration from affecting the rider's comfort. Furthermore, the parallel and spaced arrangement of the two damping sections 3 ensures the stable placement of the battery 7 within the battery mounting cavity 1. The connecting section 4 is fixedly connected to the adjacent damping section 3 with a smooth transition, enhancing the stability of the bottom wall structure 2.

[0032] Specifically, in order to further optimize the vibration reduction effect, openings that penetrate the bottom wall 2 are reserved at both ends of the vibration damping part 3 in the length direction and between the bottom wall 2, and at both ends of the connecting part 4 in the length direction and between the bottom wall 2. In this way, when the vibration damping part 3 and the connecting part 4 undergo elastic deformation, the openings can provide a larger deformation space, preventing the bottom wall 2 from hindering the elastic deformation of each vibration damping part 3 and the connecting part 4, and further enhancing the vibration reduction effect.

[0033] Specifically, each vibration damping part 3 has a flat surface on its top to facilitate the placement and stability of the battery 7.

[0034] Specifically, each vibration damping part 3 has anti-slip textures on its top surface to increase the friction between the battery 7 and the vibration damping part 3 and prevent the battery 7 from slipping during vibration.

[0035] Specifically, the battery mounting structure also includes an elastic strap 8. Connecting ears 9 are welded to the two side walls of the battery mounting cavity 1 to ensure the firmness and stability of the connecting ears 9. The two ends of the elastic strap 8 are respectively tied to the two connecting ears 9. The elastic strap 8 is used to elastically fix the battery 7. When the battery 7 vibrates, the elastic strap 8 fixed on the battery 7 can also undergo elastic deformation to disperse some of the vibration energy and further enhance the vibration reduction effect.

[0036] In addition, the battery mounting structure also includes a cover plate (not shown in the figure), which covers the top of the battery mounting cavity 1. A gap is left between the cover plate and the elastic strap 8 to form a third vibration damping space. The third vibration damping space is used to prevent the battery 7 from directly contacting the cover plate when it vibrates, thereby reducing the risk of physical damage caused by the collision between the battery 7 and the cover plate. The existence of the third vibration damping space also provides space for the elastic strap 8 to deform elastically, ensuring that the elastic strap 8 can undergo elastic deformation to further disperse and absorb the vibration energy of the battery 7.

[0037] In other embodiments, the bottom wall has two or more upwardly protruding damping portions 3, and each pair of adjacent damping portions 3 is provided with a downwardly extending connecting portion 4. Each connecting portion 4 is fixedly connected to the adjacent damping portion 3 and the connection is smooth.

[0038] In other embodiments, the storage battery 7 may also be composed of multiple small batteries, each of which is placed on a vibration damping part 3.

[0039] In other embodiments, each damping part 3 is made of an elastic material and each connecting part 4 is made of a material with high stiffness. When the battery 7 is subjected to external force and shifts to a certain extent, the connecting part 4 does not undergo elastic deformation. Only each damping part 3 is subjected to external force elastic deformation to squeeze each first damping space 5 to absorb vibration energy.

[0040] In other embodiments, each connecting part 4 is made of an elastic material and each damping part 3 is made of a material with high stiffness. When the battery 7 is subjected to external force and shifts to a certain extent, the damping part 3 basically does not undergo elastic deformation. Only each connecting part 4 is subjected to external force elastic deformation to squeeze each second damping space 6 to absorb vibration energy.

[0041] In other embodiments, each connecting ear 9 is integrally formed with the sidewall of the battery mounting cavity 1.

[0042] This utility model embodiment also provides a pedal-type electric vehicle, including a foot pedal 10, and the foot pedal 10 is provided with the battery mounting structure as described above.

[0043] The working process of this utility model is as follows: In practical applications, when the motor vibrates or the vehicle bumps, the battery 7 is displaced to a certain extent by external force. At this time, the vibration damping parts 3 and connecting parts 4 located below the battery 7 can undergo elastic deformation to absorb and disperse the vibration energy of the battery 7. The first vibration damping space 5 formed at the lower part of the vibration damping part 3 and the second vibration damping space 6 formed at the upper part of the connecting part 4 provide space for the elastic deformation of the vibration damping part 3 and the connecting part 4, thereby enhancing the vibration damping effect. In addition, an elastic strap 8 is fixed to the top of the battery. The elastic strap 8 can also undergo elastic deformation to absorb some of the vibration energy. The vibration will not be directly transmitted to the bottom of the battery mounting slot and the foot pedal. Through effective vibration damping, the vibration energy of the battery 7 when subjected to external force is significantly reduced, avoiding the vibration from affecting the rider's comfort.

[0044] In summary, this utility model provides a battery mounting structure and a pedal-type electric vehicle. By providing at least two upwardly protruding damping parts on the bottom wall, and providing a downwardly extending connecting part between each pair of adjacent damping parts, each connecting part is fixedly connected to the adjacent damping parts and smoothly transitions. The lower part of each damping part forms a first damping space, and the upper part of each connecting part forms a second damping space. The battery is placed on the damping parts, and / or the battery is placed on the upper side of each damping part and each connecting part. Each damping part and / or each connecting part is elastically deformed by external force to compress the first damping space and / or the second damping space, effectively absorbing and mitigating battery vibration and improving rider comfort.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
