Description

Battery holder for saddle type vehicle

Technical Field

The present subject matter relates to a saddle type vehicle. More particularly, the present subject matter relates to the mounting of energy sources for saddle-type vehicles.

Background

In a conventional saddle-ride type vehicle with an IC engine as the powertrain, there is an energy storage unit, such as a battery, to provide spark for ignition. In addition, batteries are used to power lights, speakers, and other auxiliary functions. In a vehicle of an Electric Vehicle (EV) powertrain, at least one energy storage unit is implemented to provide energy to various functions of the vehicle (e.g., motion, electronic Control Unit (ECU), electrical loads, etc.). The battery is fixed to the saddle type vehicle by using the battery holder and the mounting bracket.

Further, when traveling on a bump or a decelerator, the battery is displaced from the battery holder due to the inertia of the battery. Furthermore, this can lead to loosening of the connector pins in the wires and the battery may fall out of the battery holder or loosen during use due to road loads and vibrations.

Detailed Description

In a saddle type vehicle, when riding on a road through bumps or decelerating, the battery is easily displaced from the battery holder due to loosening of the connector pins in the electric wire, and the electric device is also loosened. However, the embodiment in which the battery clamp is provided on the top surface of the battery fixes the battery to the holder by providing a preload force and prevents displacement thereof, so that the number of parts of the saddle type vehicle increases, which increases the weight of the vehicle and also increases the assembly time of the vehicle. Also, when the battery position deviates from the center plane of the vehicle, this results in an undesirable increase in mass, hindering the maneuverability of the saddle type vehicle.

It is customary to mount batteries and other electrical equipment in a rigid manner that is not movable unless removed or adjusted by use of a tool. A rigid mounting must be employed to prevent the battery from being dislodged from the battery holder and to avoid loosening of the electrical device. Further, a rigid structure is required to prevent one of the plurality of components from interfering with or damaging another of the plurality of components by changing the position or angle of any of the plurality of components relative to each other. Also, energy storage devices are very heavy and often cumbersome, and it is a challenge to arrange them on a vehicle, to maintain a compact package and layout of the vehicle, and to provide a stable mounting structure while bringing their mass closer to the Center of Gravity (CG) of the vehicle.

The various components include batteries and electrical components, both of which need to be placed to ensure a comfortable and careless riding experience for the rider. However, in the known art, the battery is generally mounted on the side of the saddle type vehicle. For batteries arranged below the storage compartment, removal and maintenance of the battery is generally not easy, since it is hindered by the traversing side-by-side tubes. There is always a conflicting challenge of providing a stable packaging structure for the battery while making assembly easy and facilitating manufacturing and maintenance. Although the stability and poor vehicle dynamic performance are compromised because the CG of the battery cell is far from the vehicle CG, arranging the battery cell far from the main structural components of the frame tends to improve ease of access. The deeper the depth of the battery unit into the vehicle, the more difficult access and assembly becomes. Additionally, it is often necessary to package other electrical components with the battery in the vicinity of the battery cells. Multiple brackets are provided on the vehicle structure to mount the battery cells and electrical components, which makes the system design complex, expensive, difficult to manufacture, and undesirable. Typically, the battery cells are arranged in a battery holder, which in turn is mounted to the vehicle structure by a plurality of mounts. The battery holder takes up additional valuable layout space of the vehicle, increases cost, increases the number of parts and is not conducive to ease of assembly and access to the tools for mounting the battery unit to the vehicle.

Accordingly, there is a need for an improved battery cell mounting structure/retainer that overcomes all of the above-referenced problems and others known in the art.

The present subject matter discloses a web beam clamp structure to provide a stable mounting while securing a plurality of components including a battery and electrical components to a battery unit together with a battery holder.

According to one aspect of the invention, the web beam clamp structure is mounted to the bridge member of the frame using a single mounting device provided at the end of the tail portion of the clamp.

In accordance with one aspect of the present subject matter, the web beam clamp structure is configured to directly mount the battery unit (without a battery holder), which limits movement of the battery in the vertical and lateral directions when viewing the saddle-type vehicle in a longitudinal axis side view. Further, according to an aspect of the present invention, at least one of the vertical sidewall surfaces of the battery coincides with at least one of the vertical claw portions of the jig to ensure stable mounting and good stability of the battery cell.

According to an aspect of the present invention, the web beam clamp structure is capable of properly juxtaposing at least three electrical components in the vicinity of the battery while ensuring a compact layout and packaging. The present subject matter eliminates the necessity of providing separate/dedicated mounting brackets/devices for the electrical components, thereby reducing the overall component and vehicle costs.

According to one aspect of the invention, the material of the web beam clamp structure used herein is plastic, which ensures a reduction in weight of the saddle type vehicle. Further, according to an aspect of the invention, the web beam clamp structure is made of plastic and provided with flanges and ribs to ensure the strength of the clamp.

According to an aspect of the invention, the side portion of the web beam clamp structure is provided with at least one hole on at least one tail portion to enable stable attachment of the web beam clamp structure to the vehicle frame structure. According to one embodiment, the tail portion is attached to a bridge member of the frame structure arranged substantially below the seat portion. The web beam clamp structure is configured with at least two jaw portions, each jaw portion being located on a lateral end of a centrally configured beam portion. Additionally, the web beam clamp structure is configured with at least a known attachment mechanism having a substantially orthogonal center arrangement on the top portion of the beam, and the web beam clamp structure is configured with a pair of clips on the attachment portion, each clip located on a lateral side upper surface portion of the beam structure, proximate the claw portion. The web beam clamp structure thus disclosed enables stable mounting of the battery and the electrical component, thereby reducing the cost of fixing the electrical component and also reducing the assembly time.

According to one aspect of the invention, the center plane of the vehicle coincides with the center plane of the battery, resulting in the center of mass or CG of the battery being very close to the center of mass or CG of the vehicle, which in turn improves stability and dynamic handling of the saddle type vehicle. For ease of reference, the terms "web beam clamp structure" and "clamp" are used interchangeably throughout this specification.

According to one aspect of the invention, the battery is mounted directly to the clamp structure and the ends of the battery are protected by the seat. Further, according to one aspect of the invention, the air cleaner is placed in a juxtaposed orientation relative to the battery unit, and both the air cleaner and the battery unit are disposed substantially in a central triangular region beneath a rider seat portion of the vehicle and are surrounded by a closed frame portion that forms a substantially triangular enclosure as viewed in a side view of the vehicle. The substantially triangular enclosure on the frame structure is made up of frame upper pipe members, frame rear side pipe members and frame front side pipe members. The geometry of the air cleaner is configured such that it has a recess forming a battery receiving portion that closes at least one of the left, right and bottom portions of the battery cell, thereby protecting the battery cell from external components entering the battery by at least one of the walls of the air cleaner receiving recess portion. According to one embodiment of the invention, at least one side wall of the battery unit is substantially parallel to the rear side tube of the frame structure. According to one aspect of the invention, the battery unit receiving recess portion of the air cleaner assembly has a base portion that is substantially orthogonal to a vertical axis of the battery unit and substantially orthogonal to the rear side tube of the frame structure. Since the battery can be easily removed by removing the seat and releasing the jig, easy maintenance of the battery can be ensured.
