Description

Electronic component housing in saddle-ride type vehicle

Technical Field

The present subject matter relates to a saddle-ride type vehicle. More particularly, the present subject matter relates to the mounting of housing members in a saddle type vehicle, referred to herein as a vehicle.

Background

Conventionally, most vehicles are driven by internal combustion engines using fossil fuels as energy sources. Gases formed from the combustion of fossil fuels within internal combustion engines are emitted from such vehicles into the atmosphere, which results in increased air pollution in the atmosphere.

At present, in view of this, an electric vehicle using electric energy as a power source is used as a substitute for a vehicle using fossil fuel. However, such electric vehicles need to be equipped with energy storage devices having large capacities to propel the vehicle over long distances. Accordingly, electric vehicles typically include an electric motor and drive system supported on a frame and enclosed in the vehicle body to propel the vehicle a significant distance. The energy storage unit is connected to the motor to provide power thereto. In addition, the demand for Electric Vehicles (EVs) is currently increasing due to the increasing scarcity of fossil fuels and carbon dioxide emissions from conventional internal combustion vehicles. EVs utilize electric power to drive an electric motor that operates electric power stored in an energy storage unit to power a vehicle.

Detailed Description

Over the years, the technical fields related to transportation have changed enormously, so the current attention is focused on manufacturing efficiency and costs, including the cost of materials, assembly costs, the cost of inventory handling, and the like. At the same time, there is a continuing need in the industry to provide vehicles that are stronger, lighter, and less power consuming and that are economically advantageous. Power storage device driven vehicles are just environmentally friendly, conforming to the environmental protection (Go Green) initiative of various organizations. These vehicles may be two-, three-, or four-wheeled vehicles, and have a variety of applications, depending on the requirements of the consumer.

In the automotive industry, electric vehicles are introduced to control air pollution caused by internal combustion engine driven vehicles. At present, electric vehicles are classified into two major types, i.e., pure electric vehicles and extended electric vehicles (also referred to as hybrid electric vehicles). Hybrid vehicles have a primary electric drive with an associated energy storage device and an internal combustion engine coupled to an electric motor/generator.

In recent years, electric vehicles have become quite popular due to the high oil prices and the environmental impact of pure gasoline fueled vehicles. Electric vehicles using an electric motor as a driving source and hybrid vehicles combining other driving sources such as an electric motor and an engine have been put to practical use. The above-mentioned automobiles are equipped with electronic components such as energy storage devices for supplying an electric energy source as electric power to the electric motor. In this particular type of vehicle, the motive power for the vehicle is provided by an energy storage device to receive the energy required to propel the vehicle. As the energy storage device, a battery that can be repeatedly charged and discharged, such as a nickel cadmium battery, a nickel hydrogen battery, a lithium ion battery, is used. The energy storage device is housed in a chassis and mounted on the vehicle.

Accordingly, stacked primary energy storage devices are typically developed while maintaining energy efficiency. Typically, the main energy storage device provides an output of 48 volts and converts the high voltage to the voltage required for operation of other electronic components, such as headlamps, through a DC-DC converter. A DC-DC converter, such as a controller, converts a Direct Current (DC) source from one voltage level to another and operates only when the primary energy storage device is in a wake-up state.

Furthermore, in certain situations, for example, in the event of a vehicle collision or accident at night or in a parking situation, some electronic components, such as headlamps, require a minimum voltage to be active/switched on, which can lead to depletion of the primary energy storage device. In addition, in other situations, such as when the vehicle is parked midway through a malfunction, the controller sends a command to the instrument cluster in the form of an error code to alert the user to the reason for the vehicle being parked. This requires that the primary energy storage device always function properly, which is not possible because the primary energy storage device may be depleted, which may leave the user stranded. This also raises safety concerns for the user. In this regard, in order to alleviate the load on the primary energy storage device, an energy storage device, i.e., an auxiliary energy storage device, has also been developed, which is a low voltage energy storage device.

The primary energy storage device provides energy or power to the electric machines of the vehicle, while the secondary energy storage device provides energy or power to electronic components such as headlamps, warning lights (hazard lamps), ECUs, and the like. Auxiliary energy storage devices have been developed to relieve the load on the primary energy storage device. The auxiliary energy storage device provides assistance to the power supply of the main energy storage device to provide voltage to electronic components such as an ECU (electronic control unit) operating at a low voltage (e.g., 12V) and/or to wake up the main energy storage device.

Auxiliary power supplies have been provided for overloading the main energy storage devices during operation of electronic components such as controllers, motors, headlamps, tail lamps, other communication devices, and the like. Auxiliary power sources, such as auxiliary energy storage devices, in addition to the primary energy storage devices, often exclusively satisfy the electrical load formed by these elements. In order to conserve energy to the greatest possible extent in the main energy storage unit, the auxiliary energy storage unit, etc., it is desirable to eliminate any energy losses, including transmission losses. Accordingly, it is desirable to have a short harness length, including placing the electrical load, controller, and motor in close proximity. From the above, it can be seen that the electronic components of the main energy storage device, the auxiliary energy storage device, the controller, the motor, etc. should be tightly mounted so that there should not be any voltage drop and any undesirable bending in the wiring of the high current carrying lines, while maintaining easy accessibility and maintainability.

Furthermore, there are challenges to configuring such critical electronic components in a way that is theft and tamper resistant. However, since the vehicle has a compact layout with different conventional arrangements of necessary elements, there is a limit to sufficient space to configure the main storage, auxiliary energy storage, controller, motor, etc. electronic components. Accordingly, there is a challenge to achieve a compact layout for a saddle-ride type vehicle in which electronic components, such as auxiliary energy storage devices, controllers, and other electronic components, need to be closely arranged in a reliable, safe manner while still being easy to assemble and maintain.

Generally, according to known techniques, a frame assembly includes a housing member, wherein the housing member is configured to store various electronic components, such as energy storage devices, motors, and the like. Further, the housing members are mounted to eight mounting plates existing in the frame assembly, i.e., left and right mounting plates located at the upper portion of the main frame. The lower frame has a pair of left and right mounting plates at a middle portion and a pair of left and right mounting plates at a lower portion. Further, the lower frame portion of the frame assembly has a pair of left and right mounting plates at a rear portion of the frame assembly. Electronic components such as energy storage devices are arranged at the front upper part of the motor to form a three-side closed structure. However, this configuration causes another problem such as increase in assembly and disassembly time. Further, the increase in the number of mounting boards leads to an increase in the number of welding elements for mounting the housing member, and also deteriorates the strength of the mounting boards at the welding area. Furthermore, the increased number of components also results in an increased overall cost of the vehicle and also in increased maintenance time, since the components are not readily available.

Therefore, designing a safe housing member for the electronic components of a compact two-wheeled vehicle presents a contradictory challenge, which is a vehicle that can ensure safety and ease of assembly for a user who owns the two-wheeled vehicle without any significant change in layout design and manufacturing settings.

Accordingly, there is a need for an improved layout of the housing members to accommodate the electronic components of the primary energy storage device, the secondary energy storage device, the controller, the motor, etc., while reliably and safely protecting the electronic components while maintaining the layout of the conventional vehicle. There is a need for a solution for a secure housing member for electronic components that is easy to access or repair while overcoming all of the above problems and other problems of the known art.

The present invention provides a solution to the above-described problems while meeting the requirements of minimal vehicle modifications, low cost, easy access to and maintenance of rigidity of the housing components, etc.

In view of the above, the present invention relates to a saddle type vehicle, and more particularly to an improved mounting of a housing member that reliably protects electronic components while maintaining the rigidity of the housing member.

According to one aspect of the present invention, a frame assembly includes a head pipe disposed at a front portion of a saddle-ride type vehicle, and a main frame extending from the head pipe and gradually extending downward toward a rear portion and being bent toward a bottom portion at an intermediate portion of the saddle-ride type vehicle, which is generally referred to as a center frame. The lower frame sharply extends downward from the head pipe, a pair of seat frames horizontally extends rearward from a middle portion of the main frame, and a pair of side pipes extends from a free end of the main frame to connect the pair of seat frames at a point located at a predetermined distance from a starting point of the pair of seat frames.

Further, according to an aspect of the present invention, a housing member for enclosing various electronic components is mounted or detachably attached between the lower frame and the centering frame by various attachment means such as fasteners, and also serves as a stress member of the frame assembly. The housing member has a sloped profile toward the front side of the saddle type vehicle that is complementary to a downward profile of the lower frame of the frame assembly. Further, the housing member has a mounting bracket at a front side of the housing member, which is conformed to a contour of a bracket existing at a lower end of the lower frame. The housing member has a mounting plate at the rear side that is removably attached with a mounting bracket at the lower end of the centering frame of the frame assembly. This arrangement ensures a stable and rigid mounting of the housing member to the frame assembly while reducing the number of components.

Further, according to an aspect of the invention, the housing member is divided into two compartments separated by a common partition. The first compartment has three sides, with the front side having a profile extending outwardly relative to the common partition, followed by a straight profile. This contour of the front side of the first compartment of the housing member is complementary to the contour of the lower frame and the reinforcement member attached between the main frame and the lower frame. The upper side of the case member has a backward inclined profile and is bent toward the bottom to form a third side. The third side formed is integrally attached to the common bulkhead and is also complementary to the centered frame of the frame assembly. Further, according to an aspect of the invention, the second compartment has three sides, wherein an upper end of the front side has a recessed portion forming a continuous contour with the outwardly extending contour of the front side of the first compartment of the housing member. The lower end of the front side has a mounting bracket which is complementary to the profile of the mounting bracket present at the lower end of the lower frame of the frame assembly. The underside of the second compartment serves as a stress-bearing member for the housing member. The rear side of the second compartment has a mounting plate that is complementary to the profile present on the lower end of the centering frame of the frame assembly with various attachment means, such as fasteners. This arrangement eliminates interference (fool) of the housing member with other parts of the frame assembly and also ensures stable and secure mounting of the housing member in a limited space.

Further, according to an aspect of the invention, the first compartment of the housing member is configured to store an electronic component, such as an interchangeable or primary energy storage device, and is covered or locked with a cover. The lid is provided with a locking mechanism to allow authorized access. Furthermore, according to another aspect of the invention, the cover of the first compartment itself can detachably attach the primary energy storage device and place it in the first compartment of the housing member, ensuring a safe and secure placement of the primary energy storage device in the first compartment of the housing member.

Further, according to an aspect of the invention, the second compartment of the housing member is configured to store various electronic components, such as an auxiliary energy storage device, a motor, a controller, a battery management system, and the like. The second compartment of the housing member has various projections, or ribs or slots, configured to store electronic components, e.g., projections disposed in the second compartment to store the motor in the second compartment of the housing member. The second compartment is covered by a cover that is removably attached to the second compartment of the housing member by various attachment means, such as fasteners. The cover has a slot that conforms to the contour of the shaft present on the motor. This arrangement thus ensures the theft-proof accommodation of the electronic components in the housing member. This arrangement also ensures easy access to the electronic components for servicing, thereby reducing the servicing time of the vehicle. The electronic components are tightly packed, ensuring a reduction in the length of the wiring harness, thereby reducing the voltage drop, while increasing the life expectancy of the wiring harness.

Further, according to one aspect of the invention, the second compartment of the housing member is subjected to stresses exerted by the vehicle. Thus, the second compartment of the housing member is configured with an increased cross-sectional area compared to the first compartment of the housing member. More specifically, the cross-sectional modulus of the second compartment of the housing member is greater than the cross-sectional modulus of the first compartment of the housing member. The section modulus is defined in layman language as the strength of a given component. The bending stress of a material is inversely proportional to the section modulus. Therefore, according to this relationship, the larger the section modulus, the smaller the bending stress of the case member. Thus, a higher stiffness of the housing member is ensured in parallel by this relation, while the stress-bearing capacity of the second compartment of the housing member is ensured.

Further, according to an aspect of the present invention, the housing member is provided with heat radiating fins on three sides of the housing member. Since the electronic component arranged in the case member is in direct contact with the surface of the case member, heat emitted by the component is transferred to the surface of the case member. Further, the atmosphere is guided to the heat radiating fins of the housing member, thereby ensuring removal of heat transferred to the surface of the housing member.

Further, "front" and "rear" and "left" and "right" mentioned in the following description of the illustrated embodiment refer to the front-rear and left-right directions as viewed in a state of being seated on the vehicle seat and looking forward. Further, the longitudinal axis refers to a front-to-rear axis relative to the vehicle, while the lateral axis generally refers to a left-to-right axis relative to the vehicle.

The present invention will now be described briefly with reference to the accompanying drawings. It should be noted that throughout the description, similar elements are denoted by the same reference numerals.

In the following exemplary aspect, the vehicle is a ride-on electric vehicle. However, it is contemplated that the concepts of the present invention may be applied to any two-wheeled vehicle, including hybrid electric vehicles.

Fig. 1 is a left side view of an exemplary saddle-ride type vehicle, and fig. 2 is a perspective view of a frame assembly (200), according to one embodiment of the present subject matter. A vehicle (100) has a frame assembly (200) as a framework that bears a load. An instrument cluster (119) is mounted on the handlebar assembly (126). The handlebar assembly (126) is pivotally disposed through the head tube where it includes a brake lever (not shown). The handlebar assembly (126) is connected to the front wheel (129) by one or more front suspensions (130). A front fender (131) is disposed above the front wheel (129) for covering at least a portion of the front wheel (129). A leg shield (not shown) is provided on the vehicle (100). The vehicle (100) has a lighting device including a head lamp (127), a tail lamp (106), and turn indicator lamps including a front side indicator lamp (not shown) and a rear side indicator lamp (not shown), respectively. A rear fender (138) projects outwardly from the vehicle system, and it protects the rear seat from mud splash and protects the rear wheel (133) from external elements. A rear wheel arm (not shown) is mounted on the left side of the swing arm, and further, the license plate illuminator, and the light reflecting reflector are mounted on the rear wheel arm. The seat (132) extends in a longitudinal direction along the seat frame.

A frame assembly (200) of a vehicle (100) is provided with a head pipe (201), and the head pipe (201) includes a main frame (202) extending slightly downward from the head pipe (201) rearward, a pair of seat frames (205) extending rearward from the main frame (202), a lower frame (203) extending substantially downward from the head pipe (201), and a pair of center frames (204) extending downward from the rear of the main frame (202). The area enclosed by the seat frame (205), the centering frame (204) and the sub-frame (not labeled) is generally triangular in side view. Further, according to one embodiment of the present invention, the housing member (134) is mounted to a lower portion of the frame assembly (200). The frame reinforcing member (207) is integrally attached to the connecting portion of the head pipe (201) with the lower frame (203) and the main frame (202), ensuring the rigidity of the frame assembly.

Further, according to one embodiment of the present invention, a housing member (134) for enclosing various electronic components is mounted or detachably attached between the lower frame (203) and the centering frame (204) of the frame assembly (200) by various attachment means such as fasteners. The housing member may be removably attached to either side of the frame assembly (200). The housing member (134) has an inclined profile toward the front side (F) of the saddle-ride type vehicle (100) that is complementary to a downward profile of a lower frame (203) of the frame assembly (200). Furthermore, the housing member (134) has a mounting bracket (210) at the front side of the housing member (134), which detachably attaches at least one component (208 a) and thus complements the contour of the mounting bracket (208) present at the lower end of the lower frame (203) (as shown in fig. 2a and 4). This ensures easy assembly of the heavy powertrain system, which is enclosed within a housing member (134) for easy assembly and which can be removed from the side for servicing.

The housing member (134) has a mounting plate (shown in fig. 2 b) on the rear side which is complementary to a profile (209), which profile (209) is present at the lower end of the centering frame (204) of the frame assembly (200). This arrangement ensures a stable and rigid mounting of the housing member to the frame assembly while reducing the number of components.

Fig. 3 is a perspective view of a housing member according to one embodiment of the invention. Furthermore, according to one embodiment of the invention, the housing member (134) is divided into two compartments (301, 302) separated by a common partition (303). A common bulkhead (303) is arranged horizontally with respect to the vehicle at a middle portion of the case member (134). The first compartment (301) has three sides (301 a,301b,301 c), wherein the front side (301 a) has an outwardly extending profile (301 a') with respect to the common partition (303) followed by a straight profile (301 a "). The contour of the front side (301 a) of the first compartment (301) of the housing member (134) is complementary to the contour of the lower frame (203) and the reinforcement member (207) attached between the main frame (202) and the lower frame (203) (as shown in fig. 2). The upper side (301 b) of the case member (134) has a rearwardly inclined profile and is bent toward the bottom to form a third side (301 c). The third side (301 c) is formed integrally attached to the common bulkhead (303) and is also complementary to the profile of the centering frame (204) of the frame assembly (200). Furthermore, according to one embodiment of the invention, the second compartment (302) has three sides (302x, 302y, 302z), wherein the front side (302 x) has a recessed portion (302 x ") at the upper end, which forms a continuous profile with the outwardly extending profile (301 a') of the first compartment (301) of the housing member (134). The lower end (302 x') of the front side (302 x) has a mounting bracket (210) which is complementary to the profile of a mounting bracket (208) present at the lower end of the lower frame (203) of the frame assembly (200). The underside (302 y) of the second compartment (302) serves as a stress member for the housing member (134) to withstand loads from systems housed within the housing member (134) as well as other vehicle loads, such as road impacts, payload, vibrations, and the like. The rear side (302 z) of the second compartment (302) has a mounting plate (307) which is complementary to a profile (209) present at the lower end of the centering frame (204) of the frame assembly (200) (as shown in fig. 2 b). This arrangement restricts the housing member from interfering with other parts of the frame assembly and also ensures stable and firm mounting of the housing member in a limited space.

Further, since the second compartment (302) of the housing member (134) is subjected to stress or load applied by the vehicle (100), the second compartment (302) of the housing member (134) is configured to have an increased cross-sectional area (304) compared to the cross-sectional area of the first compartment (301) of the housing member (134). More precisely, the cross-sectional modulus of each side (302 x,302y,302 z) of the second compartment of the housing member is larger than the cross-sectional modulus of each side (301 a,301b,301 c) of the first compartment of the housing member. The section modulus is defined in layman language as the strength of a given component. The bending stress of a material is inversely proportional to the section modulus. Therefore, according to this relationship, the larger the section modulus, the smaller the bending stress of the case member. This relationship thus ensures a high stiffness of the housing member, while in parallel ensuring the stress-bearing capacity of the second compartment of the housing member.

Further, according to one embodiment of the present invention, the case member (134) is provided with a heat sink (305) on the case member (134). Since the electronic components arranged in the case member (134) are in direct contact with the surface of the case member (134), heat emitted by these components is transferred to the surface of the case member (134). The atmosphere is directed to the fins (305) of the housing member (134) to ensure removal of heat transferred on the surface of the housing member (as shown in fig. 3a and 3 b).

Fig. 4 is a perspective view of a housing member assembled to a frame assembly in accordance with one embodiment of the present invention. Further, according to one embodiment of the invention, the first compartment (301) of the housing member (134) is configured to store an electronic component, such as an interchangeable or primary energy storage device (404), and is covered or locked by a cover (401). The lid (401) is provided with a locking mechanism to allow authorized access. Furthermore, according to another aspect of the invention, the cover (401) of the first compartment (301) itself can detachably attach the primary energy storage device and place it in the first compartment of the housing member, ensuring safety and ensuring that the primary energy storage device is placed in the first compartment of the housing member. Furthermore, when servicing or replacing the energy storage device, the main energy storage device can be easily accessed by pulling the cover (401) with the securing means (403), thereby ensuring easy access to the components and reducing the serviceable time. According to one embodiment, the outer profile of the energy storage device (404) conforms to the inner circumferential profile of the first compartment (301), enabling easy lateral assembly or loading of the energy storage device into the first compartment using suitable guiding means (e.g., wedges, roller bearings, dovetail couplings, etc.).

Further, according to one embodiment of the invention, the second compartment (302) of the housing member (134) is configured to store various electronic components, such as an auxiliary energy storage device (408), an electric motor (409), a controller (407), a battery management system, and the like. The second compartment (302) of the housing member (134) has various projections or ribs or slots to store and securely position electronic components, for example, a projection (306) is provided in the second compartment (302) to store the motor (409) in the second compartment (302) of the housing member (134). The second compartment (302) is covered by a cover (406), the cover (406) being removably attached to the compartment (302) of the housing member (134) by various attachment means, such as fasteners (405). The cover (406) has a slot (402) that conforms to the contour of a shaft (410) present on the motor (409), the shaft (410) further engaging with a suitable transmission (not shown) to transmit torque to the wheels. The formed groove is sealed by a sealing member to prevent the entry of dust, mud, etc. This arrangement thus ensures the theft-proof accommodation of the electronic components in the housing member. This arrangement also ensures easy access to the electronic components for servicing, thereby reducing the servicing time of the vehicle. The electronic components are tightly packed, ensuring a reduction in the length of the wiring harness, thereby reducing the voltage drop, while increasing the life expectancy of the wiring harness. According to one embodiment of the invention, the housing member (134) is divided into two compartments to accommodate the energy storage device in one of the compartments and the other electronic components in the other compartment. According to an alternative embodiment, the energy storage device may be arranged in the bottom compartment based on calibration and tuning requirements of the dynamic behavior of the vehicle. Furthermore, electronic components may be arranged in the top compartment to configure the ideal Center of Gravity (CG) height of the vehicle, thereby achieving good handling performance of the vehicle. Thus, in accordance with embodiments of the present subject matter, a housing member (134) having a modular interior space is created with suitable baffle and locating rib features. Such housing components greatly increase the flexibility of the manufacturer to configure all components in a variety of permutations and combinations while meeting various product variations, performance requirements, mileage ranges, energy storage capabilities, while still ensuring compact vehicle layout and universal frame assembly, as well as convenient assembly and maintenance of the entire powertrain and energy storage unit. According to one embodiment of the invention, the total volume of the housing member (134) is divided into two compartments, a top compartment T (301) having a volume Vt and a bottom compartment B (302) having a volume Vb. Volume ratio Vt: vb is in a range of 4:1 to 3:2, this provides an optimized and compact layout to meet all of the objectives outlined above.

The present invention helps to overcome the problem of theft or tampering (tampering) of electronic components, reduces wiring harness losses, increases accessibility to electronic components while maintaining the overall weight and width of the vehicle, and ultimately makes it cost effective.

Advantageously, embodiments of the present invention describe potential modifications in mounting housing members to securely position electrical components.

Many other improvements and modifications may be incorporated herein without departing from the scope of the invention.
