Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and more specifically, to a scooter chassis and a scooter. Background Technology

[0002] Currently, in the production process of scooters, the frame and battery pack are usually designed and manufactured separately and then assembled. The frame contains the battery compartment, while the battery pack includes an outer shell surrounding the battery module. After the battery pack is placed inside the battery compartment, the compartment and shell overlap and are used to cover and protect the battery module. This results in material waste, increasing production costs, and space waste, as it occupies more space. Furthermore, the heat from the battery module needs to pass through two layers (the battery compartment and the outer shell) to dissipate to the outside, leading to poor heat dissipation.

[0003] In view of this, designing and manufacturing a scooter chassis that is low in cost, occupies little space, and has good heat dissipation is particularly important in scooter production. Utility Model Content

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0034] Please refer to Figure 1 This utility model embodiment provides a scooter (not shown) for electric transportation. It can integrate the battery module 140 shell and battery compartment into one unit, reducing the number of parts, improving production efficiency, reducing production costs, reducing space occupation, and improving heat dissipation.

[0035] It should be noted that the scooter includes a scooter chassis 100 and a drive unit (not shown in the figure). The scooter chassis 100 is electrically connected to the drive unit, and the scooter chassis 100 is used to supply power to the drive unit to realize the drive function of the drive unit, thereby realizing the transportation function of the scooter.

[0036] The scooter chassis 100 includes a foot pedal 110, a frame base plate 120, a main control board 130, and a battery module 140. The foot pedal 110 covers and connects to the frame base plate 120, and the foot pedal 110 and the frame base plate 120 together form an accommodating cavity 150. The main control board 130 is disposed above the battery module 140 and electrically connected to the battery module 140 to realize the electronic control function of the battery module 140. Specifically, the main control board 130 and the battery module 140 are both disposed within the accommodating cavity 150, and the foot pedal 110 and the frame base plate 120 work together to protect and limit the main control board 130 and the battery module 140. In this way, the battery compartment is directly formed by the foot pedal 110 and the frame base plate 120 to protect the battery module 140, eliminating the use of the outer shell of the battery module 140 in the prior art and realizing the integration of the outer shell of the battery module 140 and the battery compartment. Firstly, it can reduce the number of parts, improve production efficiency, avoid material waste, and reduce production costs. Secondly, it can avoid space waste, reduce the space occupied, and realize the miniaturization of the scooter chassis 100. Thirdly, it can realize rapid heat dissipation of the battery module 140, quickly dissipating the heat generated by the battery module 140 to the outside, improving the heat dissipation effect.

[0037] Please refer to Figure 2 The chassis base plate 120 includes a base plate body 121 and a receiving cylinder 122. The receiving cylinder 122 is connected to the base plate body 121, and the receiving cavity 150 is disposed in the receiving cylinder 122. The main control board 130 and the battery module 140 are both disposed in the receiving cylinder 122.

[0038] The foot pedal 110 includes a foot pedal body 111 and two ribs 112. The two ribs 112 are disposed opposite each other at both ends of the foot pedal body 111, and a receiving cylinder 122 is disposed between the two ribs 112. The ribs 112 abut against the base plate body 121 and are detachably connected to facilitate the installation and removal of the foot pedal 110 and the frame base plate 120, thereby facilitating the maintenance and upkeep of the scooter chassis 100. The foot pedal body 111 abuts against the receiving cylinder 122, and a receiving cavity 150 is disposed between the foot pedal body 111 and the base plate body 121. The foot pedal body 111 covers the receiving cylinder 122 to seal the receiving cylinder 122 and prevent the main control board 130 and the battery module 140 from coming out of the receiving cylinder 122. Specifically, by providing ribs 112 on both sides of the housing cylinder 122, it is possible to quickly assemble and disassemble the ribs 112 and the base plate body 121, thereby facilitating the maintenance and upkeep of the scooter chassis 100. On the other hand, the ribs 112 can be used to reinforce and protect the sides of the housing cylinder 122, preventing deformation of the housing cylinder 122 when the scooter chassis 100 is subjected to a side impact, which could affect the performance of the battery module 140 or even cause a safety accident.

[0039] In this embodiment, the base plate body 121 and the receiving cylinder 122 are integrally formed to improve the connection strength; the pedal body 111 and the two ribs 112 are integrally formed to improve the connection strength.

[0040] Optionally, the scooter chassis 100 also includes a sealing ring 160. The sealing ring 160 abuts between the pedal body 111 and the receiving cylinder 122 to seal the gap between the pedal body 111 and the receiving cylinder 122, thereby improving the sealing performance and preventing external water from seeping into the receiving cavity 150.

[0041] Furthermore, a receiving groove 123 is provided at the top of the receiving cylinder 122, which is used to receive and limit the sealing ring 160. Specifically, the height of the sealing ring 160 is greater than the height of the receiving groove 123, and the sealing ring 160 is partially protruding from the receiving groove 123. The sealing ring 160 is elastic. When the pedal body 111 is placed on the receiving cylinder 122, the pedal body 111 can apply pressure to the sealing ring 160, so that the sealing ring 160 undergoes elastic deformation and is completely retracted into the receiving cylinder 122, thereby further improving the sealing performance and the anti-seepage effect.

[0042] Optionally, the base plate body 121 has a through hole 124, and the rib plate 112 has a threaded hole (not shown). The threaded hole is used to engage with a screw 190 passing through the through hole 124. Specifically, during the connection process between the base plate body 121 and the rib plate 112, the screw 190 is passed through the through hole 124 and tightened relative to the threaded hole to fix the relative position of the base plate body 121 and the rib plate 112, preventing the base plate body 121 from shifting relative to the rib plate 112, thereby fixing the relative position of the foot pedal 110 and the frame base plate 120.

[0043] Furthermore, there are multiple through holes 124, which are divided into two groups. Each rib 112 has multiple threaded holes, the number of which is the same as the number of through holes 124 in each group. Specifically, the multiple threaded holes are spaced apart along the length of the rib 112. Each screw 190 passes through one through hole 124 and engages with one threaded hole. The multiple screws 190 work together to improve the connection strength between the base plate body 121 and the rib 112, thereby improving the connection strength between the foot pedal 110 and the frame base plate 120.

[0044] In this embodiment, the relative positions of the foot pedal 110 and the frame base plate 120 are fixed by means of screw 190 connection, but it is not limited to this. In other embodiments, the relative positions of the foot pedal 110 and the frame base plate 120 can be fixed by means of snap-fit ​​or by means of tenon joint. The connection method of the foot pedal 110 and the frame base plate 120 is not specifically limited.

[0045] It should be noted that the battery module 140 is disposed within the receiving cylinder 122 and spaced apart from the inner wall of the receiving cylinder 122. A potting gap 170 is formed between the battery module 140 and the inner wall of the receiving cylinder 122. The potting gap 170 is used to inject adhesive to bond the battery module 140 to the receiving cylinder 122, fixing the relative position of the battery module 140 and the receiving cylinder 122 and preventing the battery module 140 from loosening or even falling out relative to the receiving cylinder 122. Specifically, adhesive is filled into the potting gap 170 to form a first adhesive body (not shown in the figure) after solidification. The battery module 140 is bonded to the receiving cylinder 122 through the first adhesive body.

[0046] Furthermore, both the battery module 140 and the housing 122 are rectangular in shape. The four sides of the battery module 140 are spaced apart from the four inner walls of the housing 122, meaning that each of the four sides of the battery module 140 has an adhesive filling gap 170. Adhesive is simultaneously poured onto the four sides of the battery module 140 to further improve the bonding effect between the battery module 140 and the housing 122 and prevent the battery module 140 from loosening or even falling out relative to the housing 122.

[0047] Please refer to Figure 3 Optionally, the inner wall of the receiving cylinder 122 is provided with multiple guide plates 125, all of which are located within the glue-filling gap 170. Each guide plate 125 abuts against the battery module 140 and is used to limit the battery module 140, facilitating its installation. Specifically, a flow channel 126 is formed between two adjacent guide plates 125. The flow channel 126 is used to guide the glue to ensure that the glue can completely fill the glue-filling gap 170, thereby improving the bonding effect.

[0048] Please refer to Figure 4 The battery module 140 includes a first bus 141, a second bus 142, and multiple individual battery cells 143. The first bus 141 is connected to one end of the individual battery cell 143, and the second bus 142 is connected to the other end of the individual battery cell 143 to achieve series / parallel electrical connection of multiple individual battery cells 143. Specifically, both the first bus 141 and the second bus 142 are electrically connected to the main control board 130 to realize the power supply function.

[0049] Furthermore, multiple individual battery cells 143 are spaced apart, forming battery gaps (not shown). These battery gaps are connected to a potting gap 170, allowing adhesive within the potting gap 170 to flow into the battery gaps. This adhesive then bonds the multiple individual battery cells 143 together, fixing their relative positions and preventing relative movement. Specifically, adhesive fills the battery gaps to form a second adhesive layer after solidification, through which the multiple individual battery cells 143 are bonded and fixed.

[0050] In this embodiment, the adhesive is a polyurethane adhesive, but it is not limited to this. In other embodiments, the adhesive can be an epoxy resin adhesive or an organic silicone adhesive. The material of the adhesive is not specifically limited.

[0051] The main control board 130 includes a circuit board (not shown), electronic control components (not shown), and battery management components (not shown). The electronic control components and battery management components are integrated on the circuit board, which is electrically connected to the battery module 140. This integration of the electronic control components and battery management components reduces the number of components and wiring harnesses, further reducing the number of parts and lowering production costs. Specifically, the electronic control component can be an MCU, and the battery management component can be a MOS.

[0052] Furthermore, the main control board 130 has an external wiring harness 131 extending from the circuit board. The external wiring harness 131 extends out of the receiving tube 122 and is used to connect an external drive device to provide power to the drive device.

[0053] Optionally, the scooter chassis 100 also includes a heat shield 180. The heat shield 180 is disposed between the main control board 130 and the battery module 140. The heat shield 180 is connected to the receiving cylinder (122) by adhesive. The heat shield 180 is used to isolate the heat of the main control board 130 and the battery module 140 to prevent the heat of the main control board 130 and the battery module 140 from affecting each other, ensuring the stability of the operation of the main control board 130 and the battery module 140, and improving safety.

[0054] It is worth noting that during the installation of the scooter chassis 100, multiple individual battery cells 143 are first spot-welded in parallel, and a first busbar 141 and a second busbar 142 are welded to both sides of each individual battery cell 143 to form a battery module 140. Then, a heat shield 180 is placed over the battery module 140. Next, a main control board 130 is installed on the heat shield 180 to achieve electrical connection between the main control board 130 and the battery module 140. Then, the battery module 140, heat shield 180, and main control board 130 are placed into the receiving cylinder 122, and the external wiring harness 131 of the main control board 130 extends out from the receiving cylinder 122. Then, the flow is directed through the guide channel 126 to the glue filling gap. Glue is poured into the 170 cavity, allowing it to flow freely into the battery gaps. This allows the glue to solidify within the 122 housing, forming a first adhesive and a second adhesive. This adhesive then bonds and fixes the battery module 140, heat shield 180, and main control board 130 within the 122 housing. Glue is also applied to the protruding parts of the external wiring harness 131. Next, the sealing ring 160 is placed in the 123 housing, and the foot pedal 110 is placed on the frame base plate 120, pressing the foot pedal body 111 against the sealing ring 160. Finally, screws 190 are used to connect the base plate body 121 and the rib plate 112, fixing the relative positions of the foot pedal 110 and the frame base plate 120, thus completing the installation of the scooter chassis 100.

[0055] The scooter chassis 100 provided in this embodiment of the utility model has a foot pedal 110 covering and connected to the frame base plate 120. The foot pedal 110 and the frame base plate 120 together form an accommodating cavity 150. The main control board 130 is disposed above the battery module 140 and electrically connected to the battery module 140. Both the main control board 130 and the battery module 140 are disposed within the accommodating cavity 150. Compared with the prior art, the scooter chassis 100 provided by this utility model, due to the foot pedal 110 and the frame base plate 120 that together form the accommodating cavity 150, as well as the main control board 130 and the battery module 140 disposed within the accommodating cavity 150, can achieve integrated design of the battery module 140 shell and the battery compartment, reducing the number of parts, improving production efficiency, reducing production costs, reducing space occupation, and improving heat dissipation. This results in lower production costs and stronger stability for the scooter.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
