Description

Technical Field

[0001] This utility model relates to the technical field of new energy vehicles, and in particular to a frame for a new energy tricycle. Background Technology

[0002] New energy tricycles are three-wheeled vehicles powered by electricity or other clean energy sources. They are mainly used for short-distance transportation, urban logistics, and personal commuting. Electric freight tricycles are used for short-distance cargo transportation and have a large cargo space and carrying capacity. Electric passenger tricycles are used for carrying passengers and are usually designed as enclosed or semi-enclosed vehicles to improve riding comfort and safety. Electric recreational tricycles are used for leisure and entertainment and are usually designed to be lightweight and suitable for short-distance travel by individuals or families.

[0003] Although new energy tricycles excel in environmental protection and economy, they still have some shortcomings in terms of frame structure stability and safety. Some low-cost new energy tricycles have overly simplified frame designs and use inappropriate materials, leading to deformation or breakage when under heavy load or used for a long time, affecting the vehicle's durability and safety. Many new energy tricycles lack specialized anti-collision structures, which can cause serious damage and injury in the event of a collision. Utility Model Content

[0004] In order to solve the problem of poor structural stability of new energy tricycles and improve driving safety, this utility model provides a frame for new energy tricycles.

[0005] The present invention provides a frame for a new energy tricycle, which adopts the following technical solution:

[0006] A frame for a new energy tricycle includes a main body support, a wheel hub support, a frame support, and a protective support. The main body support is located at the bottom of the vehicle body. The wheel hub support is located at the middle of the front end and both sides of the rear end of the main body support. The frame support is located on the upper side of the main body support. The protective support is located on the outer side and inside of the frame support. The main body support includes crossbars, longitudinal bars, and reinforcing bars. The crossbars and longitudinal bars are spliced ​​together to form the chassis main frame. The reinforcing bars are fixedly supported between the crossbars and longitudinal bars.

[0007] The main support frame forms a robust chassis frame through the splicing of crossbars and longitudinal bars. Reinforcing bars provide additional support between the crossbars and longitudinal bars, enhancing the overall structural rigidity. This design improves the frame's torsional and bending resistance, ensuring stability under high loads or complex road conditions. The frame support is located on the upper side of the main support frame, effectively distributing and bearing the weight and load of the upper part of the vehicle body. This support design optimizes the vehicle's center of gravity distribution, improves load-bearing capacity, and makes it suitable for various transportation needs. Protective supports are installed on the outer and inner sides of the frame support frame, providing an additional protective layer. This not only reduces direct damage to the vehicle body in the event of a collision but also protects the safety of passengers and cargo. The rational layout of the protective supports helps improve the vehicle's crashworthiness and safety.

[0008] Furthermore, the crossbars are arranged parallel to the vehicle's direction of travel, and the crossbars consist of two symmetrically distributed crossbars. The longitudinal bars are arranged perpendicular to the crossbars, and the longitudinal bars consist of two parallel longitudinal bars. The crossbars and longitudinal bars are spliced ​​together to form a grid pattern, and a bridging bar connects the two longitudinal bars.

[0009] The crossbars and longitudinal bars are spliced ​​together to form a grid-like structure, which creates a stable chassis frame that significantly improves the frame's torsional and bending resistance, ensuring stability under high loads or complex road conditions. A bridging bar connects the two longitudinal bars, further enhancing the frame's structural stability and overall strength. The bridging bar not only distributes and transfers the load but also effectively disperses the weight and load on the upper part of the vehicle, improving load-bearing capacity. Wheel hub brackets are located at the front middle and rear sides of the main frame to ensure the secure installation and flexible movement of the wheel hubs.

[0010] Furthermore, the reinforcing bar includes a cross bracket and a triangular bracket. The cross bracket is an X-shaped frame and is fixedly supported between two crossbars. The triangular bracket is V-shaped and is supported between the crossbar and the front end of the vehicle.

[0011] The X-shaped structure provides additional lateral and longitudinal support, enhancing the frame's torsional and bending resistance. It effectively disperses and transmits forces from different directions, improving the frame's stability under dynamic loads. The V-shaped bracket has excellent impact resistance, providing additional support during collisions or sudden braking, reducing damage to the front end. This bracket layout effectively distributes the load at the front end, enhancing the stability of the front structure.

[0012] Furthermore, the wheel hub bracket includes a front wheel guard, a rear wheel guard, and an axle mounting bracket. The front wheel guard is located at the middle of the front end of the main body bracket, the rear wheel guard is located on both sides of the rear end of the main body bracket, and the axle mounting bracket is installed on the bottom surface of the main body bracket and positioned between the two sets of rear wheel guards.

[0013] The front wheel guards are positioned at the center of the front end of the main support frame, providing additional protection and stability. They effectively protect the front wheels from damage during collisions or impacts, while ensuring stable installation and flexible movement, thus improving the impact resistance of the front structure. The rear wheel guards are positioned on both sides of the rear end of the main support frame, providing protection and support for the rear wheels. They effectively protect the rear wheels from side impacts and damage, while maintaining rear wheel stability, thus improving the overall crashworthiness and safety of the vehicle. The axle mounting brackets are installed on the bottom surface of the main support frame and positioned between the two sets of rear wheel guards. This design ensures stable axle installation and even load distribution. The axle mounting brackets effectively distribute and transfer weight from the vehicle body and cargo, optimizing the vehicle's load distribution and improving the overall load-bearing capacity of the frame.

[0014] Furthermore, the front wheel guard includes a clearance frame and a support frame. The clearance frame is concave and horizontally arranged, and the support frame is inverted U-shaped and vertically arranged. The two ends of the support frame are respectively connected to the two sides of the clearance frame. The rear wheel guard includes an arc frame and a limiting frame. The arc frame is arranged along the upper surface of the wheel body's designed installation position, and the limiting frame is arranged inside the wheel body's designed installation position.

[0015] The concave, horizontally positioned clearance frame and the inverted U-shaped, vertically positioned support frame effectively protect the wheel from damage during collisions or impacts. The concave clearance frame provides extra space for the wheel, reducing direct contact with other components or obstacles during operation. The inverted U-shaped support frame enhances structural stability and impact resistance, ensuring wheel safety under various road conditions. The arc frame is positioned along the upper surface of the wheel's designed installation location, providing additional protection for the wheel. The arc design effectively resists impacts from above, protecting the wheel from damage. The limit frame is located inside the wheel's designed installation location, ensuring the wheel's safety and stability during installation and preventing displacement or loosening during movement.

[0016] Furthermore, the vehicle frame bracket includes a skirting frame, uprights, and a top bracket. The skirting frame is arranged around the bottom surface of the vehicle body and around the ground of the vehicle body. The uprights are arranged around the skirting frame to form a side support frame for the vehicle body. The top bracket is arranged on the top surface of the vehicle body and connected to the uprights.

[0017] The baseboard frame is set around the bottom of the vehicle body and the ground, providing basic support for the vehicle body. This design can effectively increase the overall rigidity and strength of the vehicle body, ensuring that the vehicle can withstand vibrations and impacts from the ground during driving. The pillars are set around the baseboard frame and form a support frame on the side of the vehicle body. They provide vertical support for the entire vehicle body and enhance lateral stability. The presence of the pillars can effectively disperse and transmit various forces from the vehicle body and the outside world, ensuring the stability of the vehicle body under different load conditions. The roof bracket is set on the top surface of the vehicle body and connected to the pillars to form a complete support structure. The roof bracket not only provides necessary support for the roof, but also further enhances the vehicle's rollover and impact resistance. This design can effectively protect the safety of passengers when the vehicle tilts or collides.

[0018] Furthermore, the pillars include an arc-shaped pillar, a middle pillar, and a rear pillar. The arc-shaped pillars are arranged on both sides of the front end of the vehicle body and tilted backward. The middle pillar and the rear pillar are respectively arranged on both sides of the middle part of the vehicle body and on both sides of the rear end. The top brackets are arranged on both sides of the top surface of the vehicle body and connected in series to the top of the arc-shaped pillar, the middle pillar, and the rear pillar. The top brackets arranged on both sides are connected to each other through a connecting frame.

[0019] The curved pillars located on both sides of the front of the vehicle body and tilted backward effectively provide support and protection for the front. This design not only enhances the structural strength of the front of the vehicle body, but also effectively absorbs and disperses the impact force from the front, improving safety. The center pillar and rear pillar are located on both sides of the middle and rear of the vehicle body, respectively, providing continuous lateral support. These pillars enhance the lateral stability of the vehicle body and prevent tilting or deformation caused by lateral forces during driving.

[0020] Furthermore, the protective bracket includes a battery box bracket, which is installed in the vehicle body at the predetermined battery installation position. The battery box bracket has a rectangular frame structure and is equipped with a divider.

[0021] The battery box bracket adopts a rectangular frame design, which can provide all-round physical protection for the battery. This structure can effectively prevent the battery from shifting or being damaged due to vibration or impact during vehicle operation, ensuring battery safety. The battery box bracket is equipped with dividers, which can effectively separate battery cells and prevent collisions between batteries. This design can further improve battery stability and reduce the risk of damage caused by interaction between batteries.

[0022] Furthermore, the protective bracket includes a crash protection bracket, which is installed on the outer sides of the front and rear ends of the vehicle body and frame. The crash protection bracket includes a front guard and a rear guard, with the front guard installed on the outer side of the front end of the vehicle body and frame, and the rear guard installed on the outer side of the rear end of the vehicle body and frame.

[0023] The front guard is installed on the outer side of the front of the vehicle body and frame. It can absorb and disperse the impact force when the vehicle is involved in a frontal collision. This design not only protects the front structure of the vehicle, but also reduces the impact on the passengers inside the vehicle and improves safety. The rear guard is installed on the outer side of the rear of the vehicle body and frame. It can provide effective protection when the vehicle is involved in a rear collision. The rear guard can absorb the impact force, prevent damage to the rear structure of the vehicle, and protect the passengers inside the vehicle.

[0024] Furthermore, the protective bracket includes a top plate reinforcement frame, which is installed on the upper side of the vehicle body and the top of the frame, and the top plate reinforcement frame is a planar frame structure.

[0025] The planar frame design of the roof reinforcement can evenly distribute the pressure and weight from the outside world, enhancing the structural strength of the vehicle roof. This design helps prevent the roof from deforming or being damaged under pressure or impact.

[0026] In summary, this utility model has the following beneficial technical effects:

[0027] 1. The main support frame forms the bottom frame structure of the vehicle body, providing basic support.
