Description

Technical Field

[0001] This utility model relates to the field of electric bicycles, and more specifically, to an electric bicycle frame adapted for delivery drivers. Background Technology

[0002] With the booming development of the food delivery industry, the number of delivery riders is increasing daily, and their requirements for delivery tools are also rising. Delivery riders need to carry various items during deliveries, including food items and batteries. Existing electric scooter frame designs often fail to adequately consider the proper placement of these items, resulting in cluttered and disorganized items that not only affect the vehicle's balance and handling but also pose certain safety hazards. Furthermore, maintaining the temperature of food during delivery is crucial, but most existing electric scooters lack dedicated insulation and power supply devices, failing to effectively maintain the temperature of the food and impacting the customer's dining experience. Utility Model Content

[0003] In view of this, the present invention provides an electric vehicle frame adapted for delivery drivers.

[0004] The objective of this utility model is achieved through the following technical solution: An electric vehicle frame adapted for delivery riders includes a front frame and a rear frame rotatably connected, with a shock absorber between the front frame and the rear frame. A storage rack is connected to the rear frame, and a battery, a cooler box, and a junction box are mounted on the rack. A circuit board is located inside the junction box, and the battery is electrically connected to the circuit board. A heating module is located inside the cooler box, and a first wire group, a second wire group, and a third wire group are electrically connected to the circuit board. The first wire group is connected to the heating module and supplies power to it. The second wire group extends to the front frame and supplies power to electrical components on the front frame. The third wire group extends to the rear frame and supplies power to electrical components on the rear frame.

[0005] In the above technical solution, a storage rack is set on the rear frame to integrate the battery, insulated box and junction box. The structure is compact, which makes it convenient for deliverymen to pick up and put down items, and makes full use of space, making the overall design of the vehicle more reasonable without affecting the vehicle's driving flexibility and stability.

[0006] Furthermore, by incorporating a junction box with an internal circuit board, battery output is uniformly managed and distributed, forming an integrated power management center. The standardized zoned power supply mode, employing first, second, and third wiring groups, achieves functional separation of the circuits, resulting in clear and standardized wiring. The modular wiring design allows for pre-planning of the wiring connecting the front and rear frames, utilizing the frame's internal space or dedicated cable trays for installation. This effectively prevents wear and breakage caused by sun and rain, accidental pulling, and frame rotation, significantly improving safety and lifespan.

[0007] Optionally, in one possible implementation, the storage rack includes a first shelf mounted on the rear frame via several connecting rods, and a second shelf connected to the first shelf at intervals via several fixing plates; the junction box and the battery are located on the first shelf, and the insulation box is located on the second shelf.

[0008] In the aforementioned technical solution, the storage rack adopts a layered structure with the first and second shelves spaced vertically, which makes full use of the vertical space of the rear frame. Different functional components are rationally distributed across different shelves, increasing available storage and installation space and making the overall vehicle structure more compact and organized. Furthermore, placing the insulated box on the second shelf at a relatively moderate height allows delivery drivers to retrieve and place food without excessive bending or stretching of their arms, making operation easier and more convenient.

[0009] Alternatively, in one possible implementation, the junction box is located at one end of the shelf near the front frame, the junction box has a receiving space, and the circuit board is fixed in the receiving space by multiple mounting posts.

[0010] In the above technical solution, the junction box's location design allows all major cables connecting the front and rear frames to naturally converge there, achieving centralized management of the interfaces. All cables can start from the junction box and be neatly laid along the pre-set path of the frame, making the overall vehicle wiring cleaner and more concealed. Secondly, the junction box's storage space provides a relatively enclosed and safe environment for the circuit board, effectively preventing external dust, moisture, and debris from entering and avoiding corrosion and damage to the circuit board.

[0011] Optionally, in one possible implementation, one side of the circuit board is provided with a terminal block connected to the battery, and the other side of the circuit board is provided with a first terminal, a second terminal, and a third terminal respectively connected to the first wire group, the second wire group, and the third wire group.

[0012] In the above technical solution, the battery input terminal and the first, second, and third terminals of each output wire group are respectively located on both sides of the circuit board, forming a clear "input area" and "output area". This physical isolation can effectively avoid the possibility of confusing the power input line with the load output line during installation or maintenance, greatly improving the intuitiveness and accuracy of wiring operations.

[0013] Optionally, in one possible implementation, the junction box has a locking hole on the side near the terminal block, the battery has a terminal, and the terminal passes through the locking hole and is connected to the terminal block.

[0014] In the above technical solution, the locking hole design provides clear guidance and a fixed position for the installation of the battery terminals. When connecting the battery, the installer only needs to align the terminal with the locking hole and insert it, and then connect it to the terminal block, without the need for complicated alignment and adjustment operations. At the same time, the locking hole can limit the horizontal and vertical movement of the terminal, making the connection between the terminal and the terminal block more secure.

[0015] Alternatively, in one possible implementation, a waterproof rubber ring is provided at the edge of the card hole.

[0016] In the aforementioned technical solution, delivery electric vehicles frequently encounter adverse weather conditions such as rain and snow, or pass through flooded areas. The waterproof rubber ring around the edge of the locking hole forms a tight seal, preventing moisture from seeping into the interior through the gap between the locking hole and the connected components.

[0017] Optionally, in one possible implementation, the front frame has a first channel inside, the first channel passing through the front end and the rear end of the front frame, and the second line group enters the first channel from the rear end of the front frame and extends from the front end of the front frame.

[0018] In the above technical solution, the first channel inside the front frame provides an independent physical protection space for the second wiring harness. This effectively avoids direct damage to the wiring from external physical impacts, such as damage to the wiring sheath or breakage of internal conductors, thereby ensuring the integrity and normal function of the wiring.

[0019] Optionally, in one possible implementation, the rear frame has a second channel inside, the second channel having an inlet hole and an outlet hole, the third cable group entering the second channel from the inlet hole and extending out from the outlet hole.

[0020] In the above technical solution, the second channel can isolate the third line group from the influence of the harsh external environment, and also optimize the spatial layout of the line group, making the line route more regular and orderly, avoiding the lines from being messy and tangled on the outside of the rear frame. This not only makes the overall appearance of the electric vehicle cleaner, but also reduces mutual interference between the lines.

[0021] Optionally, in one possible implementation, the insulated box includes a box body and a cover, the cover being rotatably mounted on the box body, and the heating module being disposed at the bottom of the box body, the heating module being a resistance wire arranged in an "S" shape.

[0022] In the above technical solution, the cover is rotatably mounted on the housing, making the opening and closing of the cover very convenient. The heating module uses resistance wires arranged in an "S" shape and is located at the bottom of the housing. This layout can make full use of the space at the bottom of the housing, allowing the resistance wires to reach a longer length within a limited space, thereby increasing the heating area.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] Please refer to Figure 1 and Figure 2 This embodiment provides an electric vehicle frame adapted for delivery drivers, including a front frame 1 and a rear frame 2 rotatably connected, with a shock absorber 3 between the front frame 1 and the rear frame 2; a storage rack 4 is connected to the rear frame 2, and a battery 5, a heat preservation box 6, and a junction box 7 are provided on the storage rack 4. A circuit board 8 is provided inside the junction box 7, and the battery 5 is electrically connected to the circuit board 8; a heating module 611 is provided inside the heat preservation box 6, and a first wire group 81, a second wire group 82, and a third wire group 83 are electrically connected to the circuit board 8 respectively; the first wire group 81 is connected to the heating module 611 and is used to supply power to the heating module 611; the second wire group 82 extends to the front frame 1 and is used to supply power to the electrical components on the front frame 1; the third wire group 83 extends to the rear frame 2 and is used to supply power to the electrical components on the rear frame 2.

[0032] A storage rack 4 is installed on the rear frame 2, integrating the battery 5, insulated box 6, and junction box 7. The structure is compact, making it convenient for delivery drivers to retrieve and place items, and making full use of space, resulting in a more reasonable overall vehicle design without affecting the vehicle's flexibility and stability. Furthermore, the front and rear frames 2 are connected by a rotating mechanism and equipped with shock absorbers 3, which not only ensures riding comfort but also provides a structural foundation for internal cable routing.

[0033] Furthermore, by setting up a junction box 7 containing circuit board 8, the output of battery 5 is uniformly managed and distributed, forming an integrated power management center. The standardized zoned power supply mode using the first wire group 81, the second wire group 82, and the third wire group 83 achieves functional separation of the circuits, resulting in clear and standardized wiring. Moreover, the modular wire group design allows for pre-planning of the wiring connecting the front and rear frames 2, and its installation within the frame or in dedicated cable trays, effectively preventing wear and breakage caused by sun and rain, accidental pulling, and frame rotation, significantly improving safety and lifespan.

[0034] In this embodiment, the storage rack 4 includes a first shelf 41 mounted to the rear frame 2 via several connecting rods 43, and a second shelf 42 vertically spaced from the first shelf 41 via several fixing plates 44; the junction box 7 and the battery 5 are disposed on the first shelf 41, and the insulated box 6 is disposed on the second shelf 42. Specifically, the first shelf 41 and the second shelf 42 are horizontally arranged, forming a space between the first shelf 41 and the second shelf 42 for placing the battery 5. The battery 5 and the junction box 7 can be fixed to the first shelf 41 by screws or other fixing methods, and similarly, the insulated box 6 can also be fixed to the second shelf 42 by screws.

[0035] The storage rack 4 employs a layered structure with alternating upper and lower shelves 41 and 42, fully utilizing the vertical space of the rear frame 2. Different functional components are rationally distributed across different shelves, increasing usable storage and installation space and making the overall vehicle structure more compact and organized. Furthermore, the insulated box 6 is positioned on the second shelf 42 at a suitable height, allowing delivery personnel to easily and conveniently retrieve or place food without excessive bending or stretching of their arms. Additionally, the layered design prevents the battery 5 and junction box 7 from being completely covered by the insulated box 6 during operation, ensuring air circulation, promoting natural heat dissipation, and extending the lifespan of electrical components.

[0036] In this embodiment, the junction box 7 is located at one end of the shelf 4 near the front frame 1. The junction box 7 has a receiving space 71, and the circuit board 8 is fixed in the receiving space 71 by multiple mounting posts 72. The junction box 7 is a detachable structure. When installing the circuit board 8, the junction box 7 is opened and the circuit board 8 is fixed on the multiple mounting posts 72.

[0037] The location design of the junction box 7 allows all the main cables connecting the front and rear frames 2 to naturally converge here, achieving centralized management of the interfaces. All cables can start from the junction box 7 and be neatly laid along the pre-set path of the frame, making the overall vehicle wiring cleaner and more concealed. Secondly, the housing space 71 of the junction box 7 provides a relatively closed and safe environment for the circuit board 8, which can effectively prevent external dust, moisture, debris, etc. from entering, avoiding corrosion and damage to the circuit board 8.

[0038] In this embodiment, one side of the circuit board 8 is provided with a terminal block 84 for connecting to the battery 5, and the other side of the circuit board is provided with a first terminal 811, a second terminal 821, and a third terminal 831 respectively connected to the first wire group 81, the second wire group 82, and the third wire group 83. When connecting to power, the first wire group 81, the second wire group 82, and the third wire group 83 can be directly plugged into the first terminal 811, the second terminal 821, and the third terminal 831 respectively, which is simple and quick to operate.

[0039] The battery input terminal 84 and the first, second, and third terminals 831 of each output wire group are respectively located on both sides of the circuit board 8, forming a clear "input area" and "output area". This physical isolation can effectively avoid the possibility of confusing the power input line with the load output line during installation or maintenance, and greatly improves the intuitiveness and accuracy of wiring operations.

[0040] Through dedicated terminal blocks 84 and terminals, the power from battery 5 is distributed in an orderly manner to different wiring groups. The first wiring group 81 supplies power to the heating module 611 of the insulation box 6, the second wiring group 82 supplies power to the electrical components of the front frame 1, and the third wiring group 83 supplies power to the electrical components of the rear frame 2. This regional and functional power supply method makes power management more precise and efficient.

[0041] In this embodiment, the junction box 7 has a locking hole on the side near the terminal block 84, and the battery 5 has a terminal block 51, which passes through the locking hole and is connected to the terminal block 84.

[0042] The snap-fit ​​design provides clear guidance and a fixed position for the installation of battery 5 terminal 51. When connecting battery 5, the installer only needs to align terminal 51 with the snap-fit ​​and insert it, and then connect it to the terminal block 84, without the need for complicated alignment and adjustment operations. At the same time, the snap-fit ​​can limit the horizontal and vertical movement of terminal 51, making the connection between terminal 51 and terminal block 84 more secure.

[0043] It should be noted that a waterproof rubber ring 73 is provided around the edge of the card hole. Similarly, sealing rubber rings can also be provided at the parts of the first wire group 81, the second wire group 82, and the third wire group 83 that come into contact with the junction box 7 to achieve waterproofing.

[0044] In the usage scenarios of delivery electric bikes, inclement weather such as rain and snow is frequently encountered, or the bikes may pass through flooded areas. The waterproof rubber ring 73 set at the edge of the card hole can form a tight sealing barrier to prevent moisture from seeping into the interior from the gap between the card hole and the connected parts.

[0045] Please refer to Figure 3 In this embodiment, the front frame 1 is provided with a first channel 11 inside. The first channel 11 passes through the front end and the rear end of the front frame 1. The second wire group 82 enters the first channel 11 from the rear end of the front frame 1 and extends out from the front end of the front frame 1.

[0046] The first channel 11 inside the front frame 1 provides an independent physical protection space for the second wiring harness 82. During daily use of an electric vehicle, the front frame 1 may be subjected to various collisions and scratches, such as minor collisions with roadside obstacles during driving or accidental friction with other objects when parked. The second wiring harness 82, located in the first channel 11, effectively prevents direct damage to the wiring from these external physical impacts, such as damage to the wiring sheath or breakage of internal wires, thus ensuring the integrity and normal function of the wiring.

[0047] The second cable group 82 (responsible for powering the electrical components of the front frame 1, such as headlights, turn signals, and mobile phone charging) is completely built-in and protected inside the frame tubing, completely isolating it from the external environment. This effectively avoids cable aging caused by sun and rain, wear from being hit by gravel or scratched by foreign objects, and possible accidental snagging.

[0048] Please refer to Figure 1 In addition, the rear frame 2 has a second channel 21 inside, which has an inlet hole and an outlet hole. The third cable group 83 enters the second channel 21 through the inlet hole and extends out through the outlet hole.

[0049] The third wire group 83 can be used to power the motor. The second channel 21 can isolate the third wire group 83 from the influence of the harsh external environment. On the other hand, it can also optimize the spatial layout of the wire group, making the wiring route more regular and orderly, avoiding the wires from being messy and tangled outside the rear frame 2. This not only makes the overall appearance of the electric vehicle cleaner, but also reduces mutual interference between the wires.

[0050] The second wiring harness 82 is concealed within the first channel 11 of the front frame 1, and the third wiring harness 83 is concealed within the second channel 21 of the rear frame 2, making the rear appearance of the vehicle more concise and aesthetically pleasing. Without the messy exposed wiring, the electric vehicle looks more professional and refined overall.

[0051] Please refer to Figure 1 and Figure 4 In this embodiment, the heat preservation box 6 includes a box body 61 and a cover 62. The cover 62 is rotatably mounted on the box body 61. The heating module 611 is disposed at the bottom of the box body 61. The heating module 611 is a resistance wire arranged in an "S" shape.

[0052] The cover 62 is rotatably mounted on the housing 61, making its opening and closing operations very convenient. The heating module 611 uses resistance wires arranged in an "S" shape and is located at the bottom of the housing 61. This layout makes full use of the space at the bottom of the housing 61, allowing the resistance wires to reach a longer length within a limited space, thereby increasing the heating area.
