Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle technology, specifically a multifunctional electric motorcycle frame structure. Background Technology

[0002] Against the backdrop of increasingly severe energy shortages and the gradual replacement of gasoline and diesel as the driving energy source for vehicles due to the advantages of energy saving and environmental protection, the use of electric energy as a driving energy source is also gradually extending from road-type electric motorcycles to electric motorcycles in various functional scenarios. Electric motorcycles are a type of transportation tool that is driven by electricity and meets motor vehicle standards. With their environmental protection and intelligent features, they are becoming a new choice for urban travel. They are mainly divided into two categories: electric mopeds and electric motorcycles. The former is suitable for short-distance travel, while the latter can meet the needs of long-distance or fast commuting.

[0003] Common electric motorcycles mainly consist of a frame, motor, battery, and controller. The frame, as the skeleton of the vehicle, includes the frame, front fork, handlebars, etc., supporting the entire body and carrying passengers. The front fork is a key component connecting the front wheel and the frame, responsible for transmitting various forces and torques and controlling steering. It works in conjunction with auxiliary systems, such as instruments and lighting systems to display vehicle status such as battery level and speed and provide nighttime illumination, as well as braking and suspension systems to maintain driving safety and riding comfort. Conventional electric vehicles have two independent structures for the steering lock and the chassis lock. The steering lock is usually located in the middle of the front handlebars, while the chassis lock is located on the top of the dashboard.

[0004] The aforementioned electric motorcycles suffer from the following problems: their steering lock and chassis lock are two independent structures, requiring two keys or two separate operations to lock and unlock, resulting in cumbersome operation and a fragmented locking structure. Furthermore, due to the fixed frame structure, the rear seats of existing electric vehicles are usually designed with a fixed size and lack adjustability, either only suitable for passenger carrying or only focused on cargo carrying, failing to flexibly switch according to actual usage scenarios, resulting in limited functionality and insufficient applicability. Therefore, we propose a multi-functional electric motorcycle frame structure. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this utility model is to provide a multifunctional electric motorcycle frame structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional electric motorcycle frame structure, including a vehicle body, a rear seat bracket fixed to the rear end of the vehicle body, the vehicle body including a frame, and an axle bracket fixed to the top front end of the frame, a headrest shafted to the top of the axle bracket, and a handlebar bracket fixed to the center of the top surface of the headrest, an ignition lock fixed to one side of the center of the bottom surface of the headrest, and a locking pin telescopically connected to one side of the bottom end of the ignition lock, the end of the locking pin engaging with a center opening in a fixing slot, and handlebar support rods fixed to both sides of the bottom end of the headrest. The bottom end of the handlebar support rod is connected to a shock absorber and a wheel. A single support and a rear footrest are distributed sequentially on both sides of the bottom of the frame. A battery compartment is opened in the center of the bottom of the frame, and positioning slots are distributed on both sides inside the battery compartment. A foot pedal cover is fixed to the top of the battery compartment. The ignition lock also includes an ignition lock cylinder, and a lock cylinder shaft extends from the bottom end of the ignition lock cylinder. A linkage latch is fixed to the bottom end of the ignition lock cylinder. A pressure roller is fixed to the bottom end of the lock cylinder shaft, and a pressure plate is attached to one outer wall of the pressure roller. Compression springs are connected to both sides of the inner wall of the pressure plate, and a locking pin is fixed to the center of the inner wall of the pressure plate.

[0008] Furthermore, the bottom surface of the front frame is axially connected to and rotatably fitted with the axle frame, and the fixing slot is fixedly connected to the outer wall of the axle frame.

[0009] Furthermore, the locking pin forms an elastic telescopic structure with one side of the linkage latch through a pressure plate and a pressure spring, and the outer wall of the pressure plate has an inner arc shape.

[0010] Furthermore, the single support is symmetrically distributed along both sides of the bottom of the frame.

[0011] Furthermore, the rear seat support includes a rear seat frame, which is integrally fixed to the rear end of the vehicle frame. A cargo steel plate is fixed to the rear end of the top surface of the rear seat frame, and mounting holes are arranged on the surface of the cargo steel plate. Adjustment plates are fixed to both sides of the bottom end of the rear seat frame, and the center of the adjustment plate is connected to the rear wheel frame.

[0012] Furthermore, the rear wheel frame is detachable from the rear seat frame via an adjustment plate, and the adjustment plate has openings arranged on one side of its center.

[0013] Furthermore, the cargo steel plate is welded and fixed to the rear end of the top surface of the rear seat frame, and the mounting holes are symmetrically and equidistantly arranged along the center of the cargo steel plate surface.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This electric motorcycle only requires a single key to be inserted into the ignition lock cylinder and rotated to the locked position. This simultaneously triggers the ignition lock to cut off the power to the motorcycle and the locking pin to be inserted into the fixed slot of the axle bracket to lock the handlebars. When the key is rotated in the opposite direction to the unlock position, the pressure plate will move the locking pin back to its original position along with the spring elastic structure, completing the unlocking process. At the same time, the power to the motorcycle will be turned on. This allows the electric motorcycle to achieve simultaneous locking and unlocking of the handlebars and the motorcycle with only a single set of locks and a key, thereby simplifying the operation process and improving ease of use. This integrated structure reduces the number of lock parts, lowers manufacturing costs, avoids the trouble of managing multiple keys, and enhances the user experience of this electric motorcycle.

[0016] The electric motorcycle has single supports at symmetrical points on both sides of the bottom of the frame. When using and unloading, the motorcycle can be unloaded from either the left or right side according to different people's needs. The design of two sets of single supports not only allows for rotation to unload from either side at any time, but also allows it to be lifted up and laid flat at the same time, making the electric motorcycle more stable when placed.

[0017] This electric motorcycle features a cargo steel plate fixed to the top of the rear seat frame and mounting holes, allowing for a hybrid rear seat structure that can switch between a long and short seat. When cargo is needed, the cargo steel plate can be fully exposed via a removable long seat cushion, switching to a short seat mode. The exposed cargo steel plate can then be used to carry goods. When passengers are needed, the long seat cushion can be installed on the cargo steel plate to form a full long seat, enabling multi-passenger transport. This allows for quick switching between passenger and cargo carrying scenarios, making operation convenient. Furthermore, the rigid cargo steel plate ensures structural strength when carrying cargo, significantly improving the vehicle's adaptability and flexibility. Attached Figure Description

Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0028] It should also be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0029] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0030] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0031] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] This utility model provides, for example Figure 1-7The diagram illustrates a multifunctional electric motorcycle frame structure, comprising a main body 1, a rear seat bracket 2 fixed to the rear end of the main body 1, a frame 101, an axle bracket 102 fixed to the top front end of the frame 101, a headrest 103 pivotally connected to the top of the axle bracket 102, a handlebar bracket 104 fixed to the center of the top surface of the headrest 103, an ignition lock 105 fixed to one side of the center of the bottom surface of the headrest 103, and a locking pin 106 telescopically connected to one side of the bottom end of the ignition lock 105. The end of the locking pin 106 is fastened into the center opening of the fixing slot 107. The bottom of the front frame 103 is fixed with the handlebar support rod 108 on both sides, and the bottom of the handlebar support rod 108 is connected to the shock absorber 109 and the wheel 110. The bottom of the frame 101 is distributed with the single support 111 and the rear footrest 112 in sequence. The bottom center of the frame 101 is provided with the battery compartment 113, and the inside of the battery compartment 113 is distributed with the positioning slots 114 on both sides. The top of the battery compartment 113 is fixed with the foot cover 115.

[0033] To ensure the overall structural stability of this electric motorcycle during use and to facilitate unlocking and locking, such as Figure 1-7 As shown, single stands 111 are symmetrically mounted on both sides of the bottom of the frame 101 of this electric motorcycle. During use, the rider can use the corresponding single stand 111 for temporary support regardless of which side they are on after dismounting. Shock absorbers 109 and wheels 110 are symmetrically mounted at the front and rear ends of the frame 101, providing stability and comfort during riding. The battery compartment 113 has a multi-slot structure in its battery mounting area. The battery compartment 113 is divided into multiple independent and uniformly sized cavities. Conductive contacts and positioning slots 114 are provided on the side walls of each small cavity. An openable conductive connecting piece is provided between each group of adjacent small cavities, allowing a single small battery to be installed in a corresponding small cavity when using a smaller battery. The built-in conductive contacts of the battery compartment enable circuit connection. When using a large battery, it can be linked with the conductive connecting pieces between adjacent small compartments to form a combined compartment that fits the size of the large battery. After the large battery is installed in the battery compartment 113, the circuit is made conductive through the linked conductive contacts. The positioning slots 114 of each compartment work together to fix the battery on both sides. In this way, the battery compartment 113 can flexibly adapt and install various battery sizes. In short-range or long-range scenarios, users can choose a single small battery or combine large batteries according to their needs, which improves the flexibility of range adjustment. The multi-slot structure and conductive connection design inside the battery compartment 113 can ensure the circuit stability and structural robustness after different batteries are installed, and simplify the battery replacement operation.

[0034] The aforementioned frame 101 has an ignition lock 105 mounted on the handlebar 104. The ignition lock 105 includes an ignition lock cylinder 1051, and a lock cylinder shaft 1052 extends from the bottom end of the ignition lock cylinder 1051. A linkage latch 1053 is fixed to the bottom end of the ignition lock cylinder 1051. A pressure roller 1054 is fixed to the bottom end of the lock cylinder shaft 1052. A pressure plate 1055 is attached to one outer wall of the pressure roller 1054. Compression springs 1056 are connected to both sides of the inner wall of the pressure plate 1055. A locking pin 106 is fixed to the center of the inner wall of the pressure plate 1055.

[0035] The aforementioned ignition lock 105 is a common method for vehicle power control in existing technology. Its principle is that after inserting and rotating the key, the vehicle's electronic control unit performs identity verification. Upon successful verification, the electromagnet is energized, generating a magnetic field that attracts the latch to retract, thus connecting the vehicle's circuit. When power is cut off, the spring force resets the latch, cutting off the power. This type of method is common and widely used in the market, and will not be elaborated further here. The ignition lock 105 used in this electric motorcycle, however, extends the lock cylinder shaft 1052 at the bottom of the ignition lock cylinder 1051, connecting its bottom end directly to the bottom linkage latch 1053. The lock cylinder shaft 1052 and the pressure roller 1054 are integrally fixed. Simply insert the key into the ignition lock cylinder 1051 and rotate it to the locked position. When the key is turned in reverse to the unlock position, the ignition lock 105 cuts off the power to the vehicle body, and the eccentric pressure roller 1054 pushes out the locking pin 106 in sync. The locking pin 106 is inserted into the fixing slot 107 of the axle bracket 102 to lock the handlebars, thereby restricting the rotation of the handlebars. When the key is rotated in reverse to the unlock position, the pressure plate 1055 will drive the locking pin 106 to reset synchronously with the elastic structure of the pressure spring 1056, completing the unlocking. At the same time, the vehicle body power is turned on to supply power. This allows the electric motorcycle to achieve synchronous locking and unlocking of the handlebars and the vehicle body with only a single set of locks and keys, thereby simplifying the operation process and improving the ease of use. This integrated structure reduces the number of lock parts, lowers manufacturing costs, avoids the trouble of multiple key management, and improves the user experience of this electric motorcycle.

[0036] like Figure 6-7 As shown, the rear seat support 2 includes a rear seat frame 201, and the rear seat frame 201 is integrally fixed to the rear end of the vehicle frame 101. A cargo steel plate 202 is fixed to the rear end of the top surface of the rear seat frame 201, and mounting holes 203 are arranged on the surface of the cargo steel plate 202. Adjustment plates 204 are fixed to both sides of the bottom end of the rear seat frame 201, and a rear wheel frame 205 is connected to the center of the adjustment plate 204.

[0037] To enable this electric motorcycle to quickly switch between passenger and cargo carrying scenarios using the same rear seat structure, such as... Figure 6-7As shown, by fixing the cargo steel plate 202 to the top surface of the rear seat frame 201 and through the opening design, a hybrid rear seat structure that allows for switching between a long seat and a short seat can be formed. The rear seat frame 201 of the electric motorcycle can be equipped with a basic short seat component and a detachable long seat cushion through the cargo steel plate 202. When cargo needs to be carried, the cargo steel plate 202 can be completely exposed through the detachable long seat cushion on the top surface, thus switching to the short seat mode. At this time, the short seat can accommodate passengers, while the exposed cargo steel plate 202 can be used to carry goods. When passengers need to be carried, the long seat cushion can be installed on the cargo steel plate 202 to form a complete long seat, realizing the function of carrying multiple passengers. This allows the electric motorcycle to quickly switch between carrying passengers and carrying cargo, making operation convenient. Moreover, the rigid cargo steel plate 202 can also ensure the structural strength when carrying cargo, greatly improving the vehicle's scenario adaptability and usage flexibility.

[0038] In summary, when using this electric motorcycle, only a single keyhole needs to be installed on the top of the handlebar bracket 104 panel, equipped with a dedicated key. When the user needs to lock the motorcycle, they simply insert the key into the ignition lock cylinder 1051 and rotate it to the locked position. The ignition lock 105 cuts off the power to the motorcycle, and the lock cylinder shaft 1052 at the bottom of the ignition lock cylinder 1051 rotates synchronously, driving the eccentric pressure roller 1054 to engage with the pressure plate 1055. As the rotation progresses, the pressure plate 1055 and the locking pin 106 are gradually pushed out and inserted into the fixing slot 107 of the axle bracket 102, thereby restricting the rotation of the handlebars. When the key is rotated in the opposite direction to the unlock position, the pressure plate 1055... 55 will be driven by the elastic structure of the compression spring 1056 to synchronously reset the locking pin 106, completing the unlocking. At the same time, the vehicle power supply is turned on. When installing and using the battery, when using a small battery, a single small battery is installed in a small cavity, and the circuit is connected through the conductive contacts on the cavity. When using a large battery, it can be combined with the conductive connecting pieces between adjacent small cavities to form a combined cavity adapted to the size of the large battery. After the large battery is installed in the battery compartment 113, the circuit is connected through the linked conductive contacts. The positioning slots 114 of each cavity work together to fix the battery on both sides, and it can then be inserted into the sample.

[0039] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
