Description

Technical Field

[0001] This application relates to the field of scooter technology, and more particularly to an electric vehicle frame and scooter. Background Technology

[0002] Electric vehicles are widely used due to their small size, ease of operation, and flexibility. Electric scooters, electric motorcycles, and electric bicycles all fall into the category of electric vehicles. Electric vehicles use electricity as their power source and consist of a steering assembly, a frame, and a power system. The power system uses a motor to drive the wheel hub, thus propelling the electric vehicle.

[0003] Electric vehicles use batteries to power their motors, and in related technologies, the batteries are housed inside the frame. To facilitate battery access, a standing footrest is detachably attached to the frame, allowing for battery removal by removing the footrest.

[0004] However, the pedals in this technology are relatively easy to pry open, providing poor protection for the battery and making it difficult to prevent theft, which makes it easy for the battery inside the frame to be stolen. Utility Model Content

[0005] This application provides an electric vehicle frame and a scooter. The electric vehicle frame is not easily pried open, which provides better protection for the battery and ensures that the battery located inside the frame is not easily stolen.

[0006] The first aspect of this application provides an electric vehicle frame, including a support frame. The support frame is a hollow shell with an opening on one side. A footrest is provided on the open side of the support frame. The footrest is connected to the support frame. A mating portion is provided on the edge of the footrest protruding toward the support frame. A first limiting portion is formed on the side wall of the support frame corresponding to the position of the mating portion. One of the first limiting portion and the mating portion has a protrusion, and the other has a groove. The protrusion and the groove are inserted into each other to connect the mating portion and the first limiting portion.

[0007] According to the electric vehicle frame of the first aspect of this application, the cooperation between the protrusion and the groove reduces the space between the mating part and the first limiting part, making the connection between them more compact. This reduces the insertion space for thieves and the prying distance, making the pedal frame and support frame harder to pry open, ensuring the protection of the battery inside the support frame, and making the battery less susceptible to theft. Furthermore, the cooperation between the protrusion and the groove increases the connection strength between the edge of the pedal frame and the side wall of the support frame. When a thief uses a tool to pry the support frame or pedal frame using the support frame or pedal frame as a fulcrum, the direction of prying and the insertion direction of the protrusion into the groove form a certain angle, allowing the protrusion to be locked within the groove, preventing the pedal frame and support from separating, making them harder to pry open, increasing battery protection, and making the battery inside the support frame less susceptible to theft.

[0008] In one possible implementation, a gap is formed between the end face of the mating portion toward the first limiting portion and the end face of the first limiting portion toward the mating portion, the protrusion and the groove are located on the path extending along the width direction of the gap in the electric vehicle frame, and along the width direction of the electric vehicle frame, the protrusion and the groove are located inside the first limiting portion.

[0009] In this embodiment, the protrusion and the groove are located on the path of the gap extending along the width direction of the electric vehicle frame, and the protrusion and the groove are located inside the first limiting part, which can prevent the further extension of the thief tool, thereby preventing the length of the thief tool insertion, reducing its insertion effect, and increasing the difficulty of prying open the mating part and the first limiting part.

[0010] In one possible implementation, the pedal frame includes a pedal, the pedal frame includes a pedal, the two ends of the pedal are connected to the support frame along the length direction of the electric vehicle frame, the two ends of the pedal are provided with the mating part along the width direction of the electric vehicle frame, and the first limiting part is provided on both sides of the support frame corresponding to the mating part.

[0011] In this embodiment, the two ends of the pedal along the length of the electric vehicle frame are connected to the support member, and the two ends of the pedal along the width of the electric vehicle frame are provided with mating parts. The end face of the mating part is in contact with the first limiting part, and the mating part can also be connected to the first limiting part. In this way, the pedal and the support frame can be connected in both the width and length directions of the electric vehicle frame, which helps to prevent the battery inside the support frame from being stolen.

[0012] In one possible implementation, the support frame is further provided with a second limiting part, the second limiting part and the first limiting part are arranged along the width direction of the electric vehicle frame, the groove is formed between the first limiting part and the second limiting part, and the mating part is provided with the protrusion corresponding to the position of the groove.

[0013] In this embodiment of the application, a groove is formed by setting a gap between the second limiting part and the first limiting part.

[0014] In one possible implementation, along the width direction of the electric vehicle frame, the second limiting portion is located on the side of the mating portion facing the opening of the support frame, and along the height direction of the electric vehicle frame, the end of the second limiting portion extends toward the pedal.

[0015] In this embodiment of the application, by setting the second limiting part on the side of the mating part facing the opening of the support frame, with one end of the second limiting part close to the mating part and the other end close to the pedal, the mating part can be prevented from bending inward and can also serve to support the pedal.

[0016] In one possible implementation, the mating part has a first receiving cavity inside; the second limiting part has a second receiving cavity inside; and a reinforcing member is provided inside the first receiving cavity and / or the second receiving cavity.

[0017] In this embodiment of the application, by providing receiving cavities in both the mating part and the second limiting part, it can be used for wiring, and the material used in the mating part and the second limiting part can be reduced, thus reducing weight and saving costs.

[0018] In one possible implementation, the support frame includes a frame body and a frame side. Along the width direction of the electric vehicle frame, the frame side protrudes from both ends of the frame body, and the first limiting portion is disposed on the end face of the frame side facing the pedal frame. The frame side, the mating portion, and the first limiting portion all extend along the length direction of the electric vehicle frame.

[0019] In this embodiment, the support frame includes a frame body and a frame. The frame protrudes from the frame body, and a first limiting part is disposed on the frame. Then, a mating part is disposed at the position of the pedal corresponding to the first limiting part, so as to connect the mating part and the first limiting part on the outside of the frame body, avoiding occupying the internal space of the frame body. Both the first limiting part and the mating part extend along the length direction of the electric vehicle frame, that is, the two ends of the pedal frame are fitted together with the frame along the length direction of the electric vehicle frame, making the connection between the pedal frame and the support frame tighter.

[0020] In one possible implementation, both the protrusion and the recess extend along the length of the electric vehicle frame.

[0021] In this embodiment of the application, by extending both the protrusion and the groove along the length of the electric vehicle frame, the connection strength between the mating part and the first limiting part can be increased, and the sealing between the two can also be increased, making it difficult for theft tools to extend inward between the mating part and the first limiting part.

[0022] In one possible implementation, the pedal frame includes a plurality of protrusions spaced apart along the length of the electric vehicle frame, and the support frame has a plurality of recesses spaced apart along the length of the electric vehicle frame, with a one-to-one correspondence between the plurality of protrusions and the plurality of recesses.

[0023] In the embodiments of this application, by setting the protrusions as a structure with multiple intervals, the material used for the protrusions can be reduced, thereby reducing their manufacturing cost.

[0024] In one possible implementation, a third receiving cavity is formed inside the frame along a first direction.

[0025] In this embodiment of the application, by providing a third receiving cavity within the frame, the material used in the frame can be reduced, the weight of the frame can be reduced, and costs can be saved.

[0026] A second aspect of this application provides a scooter including a steering assembly, a power assembly, and the aforementioned electric vehicle frame, wherein the steering assembly is connected to the electric vehicle frame, and the power assembly is connected to the steering assembly and the electric vehicle frame.

Detailed Implementation

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0037] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0038] Figure 1 This is a first cross-sectional view of the electric vehicle frame provided in the embodiments of this application. Figure 2 This is a second cross-sectional view of the electric vehicle frame provided in this application embodiment. The X-axis direction represents the first direction, the Y-axis direction represents the second direction, and the Z-axis direction represents the third direction. It should be noted that in this application, the first direction is parallel to the length direction of the electric vehicle frame, the second direction is parallel to the width direction of the electric vehicle frame, and the third direction is parallel to the height direction of the electric vehicle frame. For ease of explanation, the first direction represents the length direction of the electric vehicle frame, the second direction represents the width direction, and the third direction represents the height direction.

[0039] See Figure 1 and Figure 2 As shown, this application provides an electric vehicle frame 300. The electric vehicle frame 300 can be used with electric vehicles, including but not limited to scooters, electric bicycles, and electric motorcycles. This application uses a scooter as an example, serving as a support structure for the scooter. The electric vehicle frame 300 not only serves as the frame of the scooter but also as a stand for the user. The electric vehicle frame 300 includes a support frame 10, which serves as the main support for the frame 300 and also as a battery carrier. The support frame 10 is a hollow shell with an opening on one side, allowing the battery to be placed inside through the opening. To facilitate battery storage, a receiving groove 111 is provided at one end of the support frame 10, allowing the battery to be stored within it.

[0040] After the battery is placed inside the support frame 10, the opening of the support frame 10 needs to be sealed to enclose the battery inside the support frame 10, preventing the battery from falling out of the support frame 10 and also preventing the battery from being stolen.

[0041] The support frame 10 of this application is further covered with a footrest 20 on its open side. After the footrest 20 is placed on the support frame 10 to close the opening of the support frame 10, the footrest 20 is connected to the support frame 10, so that the footrest 20 can be fixed relative to the support frame 10. This can prevent the footrest 20 from detaching from the support frame 10 and exposing the battery. The footrest 20 is used to close the opening of the support frame 10, and at the same time, the footrest 20 can also serve as a direct support structure, allowing the user to directly step on the footrest 20 when using the scooter.

[0042] It should be noted that the edge of the pedal frame 20 of this application protrudes towards the support frame 10 with a mating part 23. The side wall of the support frame 10 is formed with a first limiting part 12 corresponding to the position of the mating part 23. One of the first limiting part 12 and the mating part 23 is formed with a protrusion 22, and the other is formed with a groove 14. The protrusion 22 can be inserted into the groove 14, so that the mating part 23 and the first limiting part 12 can be mated and connected.

[0043] In the related technology, after the pedal frame 20 and the support frame 10 are connected, the edge of the pedal frame 20 only fits against the side of the support frame 10. By fitting the side of the pedal frame 20 and the support frame 10 together, the opening on the support frame 10 is closed. Although the pedal frame 20 and the support frame 10 are fixedly connected, this method of only fitting the edge of the pedal frame 20 against the side of the support frame 10 is not very effective at preventing theft. Specifically, there is a gap at the fitting position between the pedal frame 20 and the support frame 10, making the connection between the pedal frame 20 and the support frame 10 relatively loose. Thieves can easily insert a thin, lightweight structure (such as a crowbar or blade with a wedge-shaped end) directly into the gap between the pedal frame 20 and the support frame 10, and then use either the support frame 10 or the pedal frame 20 as a fulcrum, easily separating the pedal frame 20 and the support frame 10 using the lever principle. This makes it easier for thieves to steal the battery inside the support frame 10.

[0044] The electric vehicle frame 300 of this application has a hollow shell structure for the support frame 10. The battery can be housed inside the support frame 10 from one of its openings. The pedal frame 20 covers the opening to close it. By connecting the pedal frame 20 to the support frame 10, the battery can be sealed inside the support frame 10. The pedal frame 20 of this application has a mating part 23 on its edge. A first limiting part 12 is provided on the support frame 10 at the position corresponding to the mating part 23. A protrusion 22 and a groove 14 are also provided between the mating part 23 and the first limiting part 12. The protrusion 22 can be inserted into the groove 14. Through the insertion and engagement of the protrusion 22 and the groove 14, the mating part 23 and the first limiting part 12 are connected together.

[0045] In this application, the edge of the pedal frame 20 and the side of the support frame 10 are connected by a mating part 23 and a first limiting part 12. It is understood that the mating part 22 and the recessed part 14 reduce the space between them, making the connection more compact. This reduces the insertion space for thieves and decreases the prying distance, making the pedal frame 20 and support frame 10 less susceptible to prying and ensuring the protection of the battery inside the support frame 10. Furthermore, the mating part 22 and the recessed part 14 also increase the connection strength between the edge of the pedal frame 20 and the side wall of the support frame 10. When a thief uses tools to pry the support frame 10 and the pedal frame 20 using the support frame 10 or the pedal frame 20 as a fulcrum, the direction of the prying and the insertion direction of the protrusion 22 into the groove 14 have a certain angle, so that the protrusion 22 can be stuck in the groove 14 to prevent the pedal frame 20 from separating from the support member, making it difficult for the pedal frame 20 and the support frame 10 to be pried open, which can increase the protection effect of the battery and make it difficult for the battery inside the support frame 10 to be stolen.

[0046] When the mating part 23 and the first limiting part 12 are mated, a gap is formed between the end face of the mating part 23 facing the first limiting part 12 and the end face of the first limiting part 12 facing the mating part 23. The size of the gap in the third direction is greater than or equal to 0. That is to say, in the third direction, the mating part 23 and the first limiting part 12 can be fitted together or have a gap. It is understood that the smaller the gap, the better.

[0047] In this application, the protrusion 22 and the groove 14 are located on the path of the gap extending along the width direction of the electric vehicle frame 300. The protrusion 22 and the groove 14 block the extension path of the gap, which can shorten the distance of the gap in the second direction as much as possible. In this way, the distance between the mating part 23 and the first limiting part 12 can be further reduced, and the length of the thief tool inserted between the mating part 23 and the first limiting part 12 can be reduced. This can shorten the prying distance of the thief tool, reduce its force stroke, and make it difficult for the pedal 21 frame 20 and the support frame 10 to be pried open.

[0048] Furthermore, in this embodiment, along the second direction, the protrusion 22 and the groove 14 are located inside the first limiting portion 12. Here, the inner side of the first limiting portion 12 is relative to the support frame 10. See [link to relevant documentation]. Figure 2 The inner side of the first limiting part 12 is the side of the first limiting part 12 facing the opening of the support frame 10.

[0049] By providing the protrusion 22 and the groove 14 inside the first limiting part 12, when a thief uses a thief's tool to insert into the gap between the mating part 23 and the first limiting part 12 and extends along the gap toward the inside of the support frame 10, the protrusion 22 can block the extension path of the thief's tool, thereby hindering the further extension of the thief's tool, preventing the length of the thief's tool from being inserted, reducing its insertion effect, and also increasing the difficulty for the thief to pry open the mating part 23 and the first limiting part 12.

[0050] In some possible implementations, the pedal frame 20 includes a pedal 21 for connection to the support frame 10, and the pedal 21 serves as a direct support structure. When the pedal 21 is connected to the support frame 10, its length direction is parallel to a first direction, and both ends of the pedal 21 in the length direction are connected to the support frame 10. The width direction of the pedal 21 is parallel to a second direction, and mating portions 23 are provided at both ends of the pedal 21 along the second direction. The end face of the mating portion 23 facing away from the pedal 21 is abutted against the first limiting portion 12.

[0051] Figure 3 This is a third cross-sectional view of the electric vehicle frame provided in the embodiments of this application.

[0052] Please gather together. Figure 3 As shown, in some possible implementations, the protrusion 22 can be formed on the mating portion 23 or on the first limiting portion 12. The groove portion 14 of this application can be formed on the mating portion 23 or on the first limiting portion 12. This application will be described with the example of forming the protrusion 22 on the mating portion 23 and the first limiting portion 12 being used to form the groove portion 14.

[0053] Specifically, the end face of the mating part 23 that is used to mate with the first limiting part 12 has a protrusion protruding towards the first limiting part 12. This protrusion forms a protrusion 22. The end face of the first limiting part 12 that is used to mate with the mating part 23 has a limiting groove, which forms a recessed part 14. In this way, through the insertion and engagement between the protrusion and the limiting groove, the mating part 23 can be connected to the first limiting part 12. The protrusion 22 is formed on the end face of the mating part 23 that is used to mate with the first limiting part 12, and the recessed part 14 is formed on the end face of the first limiting part 12 that is used to mate with the mating part 23. This reduces the contact area between the mating part 23 and the first limiting part 12, and also reduces the size of the gap between the mating part 23 and the first limiting part 12 in the width direction. In this way, when a tool is inserted into the gap between the mating part 23 and the first limiting part 12, the size of the tool contacting the mating part 23 and the first limiting part 12 is reduced, which helps to reduce the force points of the tool, or even eliminates the force points of the tool, thereby improving the anti-theft effect. Moreover, the protrusion 22 of this application is located between the mating part 23 and the first limiting part 12. When the tool is inserted between the mating part 23 and the first limiting part 12, the protrusion 22 blocks the insertion direction of the tool, which can limit the insertion depth of the tool and further reduce the force points of the tool.

[0054] In this application, the first limiting part 12 protrudes from the support frame 10. The groove 14 is formed not only by the limiting groove on the first limiting part 12, but also by a gap between the first limiting part 12 and a portion of the structure of the support frame 10, forming the groove 14. For example, the support frame 10 also has a second limiting part 13 protruding from it. The second limiting part 13 and the first limiting part 12 are spaced apart, and the gap between the first limiting part 12 and the second limiting part 13 is positioned directly opposite the protrusion 22, thus forming the groove 14.

[0055] Figure 4 This is the fourth cross-sectional view of the electric vehicle frame provided in the embodiments of this application.

[0056] See also some of the possible implementation methods. Figure 2 and Figure 4 As shown, with Figure 2 and Figure 4 With reference to the perspective in the image, the position of the protrusion 22 in the mating part 23 is not limited. For example, the protrusion 22 can be provided on the side of the mating part 23 near the opening of the support frame 10, or the protrusion 22 can be provided in the middle of the mating part 23, or the protrusion 22 can be provided on the outer side of the mating part 23 (the side away from the opening of the support frame 10). In this embodiment, the example of the protrusion 22 being provided on the side of the mating part 23 near the opening of the support frame 10 is described.

[0057] In this application, a second limiting part 13 is protruding on the support frame 10. The second limiting part 13 and the first limiting part 12 are spaced apart to form a groove 14. The second limiting part 13 is located closer to the opening of the support frame 10 than the first limiting part 12, so that the second limiting part 13 is located inside the first limiting part 12 and the first limiting part 12 is located outside the second limiting part 13.

[0058] Furthermore, the mating part 23 is spaced apart from the opening of the support frame 10 along the second direction, and the second limiting part 13 is located within the gap between the mating part 23 and the opening. That is, when the pedal 21 is connected to the support frame 10, the second limiting part 13 is located inside the mating part 23. One end of the second limiting part 13 along the second direction faces the mating part 23, and this end of the second limiting part 13 is located close to the mating part 23, or the end face of the second limiting part 13 is in contact with the mating part 23. The end of the second limiting part 13 facing away from the support frame 10 extends toward the pedal 21 and extends to be located close to the pedal 21, or the end of the second limiting part 13 facing away from the support frame 10 can abut against the pedal 21.

[0059] By placing the second limiting part 13 inside the mating part 23 and making the second limiting part 13 fit against the mating part 23, the second limiting part 13 can play a supporting role, preventing the mating part 23 from bending and deforming inward, making it difficult to pry the mating part 23, thereby increasing the stability between the mating part 23 and the first limiting part 12, and also helping to prevent battery theft. Moreover, the end of the second limiting part 13 abuts against the pedal 21, providing a certain degree of support to the pedal 21, which can increase the support strength of the pedal 21.

[0060] In some feasible embodiments, the mating part 23 has a first receiving cavity 231 inside, and the second limiting part 13 has a second receiving cavity 131 inside. Both the first receiving cavity 231 and the second receiving cavity 131 are opened along a first direction. The first receiving cavity 231 penetrates the mating part 23, and the second receiving cavity 131 penetrates the second limiting part 13. By providing the first receiving cavity 231 on the mating part 23 and the second receiving cavity 131 on the second limiting part 13, the material used in the mating part 23 and the second limiting part 13 can be reduced, thereby saving the manufacturing cost of the mating part 23 and the second limiting part 13. It can also reduce the weight of the mating part 23 and the second limiting part 13, thereby reducing the overall weight of the electric vehicle frame 300.

[0061] It should be noted that when the second limiting part 13 is provided with the second receiving cavity 131, a reinforcing member 132 may also be provided in the second receiving cavity 131. The reinforcing member 132 is supported between the two ends of the second limiting part 13 along the second direction, and is used to strengthen the strength of the second limiting part 13 in the second direction, so that the two ends of the second limiting part 13 are not easily deformed.

[0062] In some feasible implementations, the support frame 10 includes a frame body 11 and a frame 15. One end of the frame body 11 has a receiving groove 111 for storing and installing batteries. The frame 15 protrudes from the end of the frame body 11 along a second direction. A first limiting part 12 is disposed on the frame 15. The frame body 11 also has a connecting structure inside, including but not limited to a snap-fit ​​structure, a fastening structure, or a screw structure, which can connect the pedal 21 to the frame body 11. When the pedal 21 is connected to the frame body 11, the upper end face of the frame 15 faces the mating part 23 protruding on the pedal 21. The first limiting part 12 and the second limiting part 13 both protrude from the upper end face of the frame 15.

[0063] It should be noted that the frame 15 can be independently set from the frame 11, and can be connected to the side of the frame 11 by welding or bonding, or the frame 15 can be integrally formed with the frame 11. In addition, the first limiting part 12 and the second limiting part 13 can be connected to the frame 15 by welding or bonding, or the first limiting part 12 and the second limiting part 13 can be integrally formed with the frame 15. In this embodiment, the frame 15, the frame 11, the first limiting part 12, and the second limiting part 13 are integrally formed, which increases the integrity of the entire support frame 10 and increases the strength of the support frame 10.

[0064] In this embodiment, it is necessary to ensure that the edge of the pedal 21 and the side of the support frame 10 are in contact and connected. Typically, when connecting the pedal 21 and the support frame 10, the pedal 21 is placed over the opening side of the frame 11, and the side of the pedal 21 facing the inside of the frame 11 is connected to the connecting structure inside the frame 11, thus achieving the connection between the pedal 21 and the frame 11. After connecting the inner side of the pedal 21 to the frame 11, the edge of the pedal 21 needs to be in contact or connected to the side of the frame 11 so that the pedal 21 closes the opening on the frame 11.

[0065] The shape of the pedal 21 is determined according to the shape of the opening of the support frame 10. For example, the shape of the pedal 21 can be circular, elliptical, or square. In this embodiment, the example is that the frame 11 is square in shape, the opening of the frame 11 is square, and the pedal 21 is square. The pedal 21 is connected to the upper end of the frame 11, which is the end of the opening of the frame 11 and also the end used for stepping. When the pedal 21 is placed on the frame 11, its ends in the length direction correspond to the ends in the length direction of the frame 11, and the two ends in the length direction of the pedal 21 are respectively connected to the two ends in the length direction of the frame 11, making the edges of the two ends in the length direction of the pedal 21 relatively stable with the frame 11, and making it difficult to pry the pedal 21 and the support frame 10 apart from this point.

[0066] However, since the two ends of the pedal 21 lack a connecting function and only fit against the two sides of the frame 11 in the width direction, they are relatively easy to pry open.

[0067] In this application, the mating part 23 is provided on the edge of the pedal 21 in the width direction, and both ends of the pedal 21 in the width direction are provided with the mating part 23. The first limiting part 12 is provided on the side of the support frame 10 in the width direction, and both sides of the frame 11 in the width direction are provided with the first limiting part 12. The two mating parts 23 and the two first limiting parts 12 are correspondingly provided. The corresponding first limiting parts 12 and mating parts 23 not only fit together at their ends, but can also be connected through the cooperation of the protrusion 22 and the groove 14. In this way, the connection strength between the edge of the pedal 21 in the width direction and the side of the support frame 10 in the width direction can be increased through the connection between the mating parts 23 and the first limiting parts 12.

[0068] It should be noted that the frame 15, the first limiting part 12 and the mating part 23 are all extended along the first direction, that is, the length of the first limiting part 12 and the mating part 23 is the same as the length of the pedal 21. In this way, the two edges of the pedal 21 in the width direction can be fully connected to the frame 11, making the pedal 21 and the frame 11 more tightly connected.

[0069] It should also be noted that a protrusion 22 and a groove 14 are provided between the mating part 23 and the first limiting part 12. The protrusion 22 can be a raised strip extending in the first direction, and the groove 14 can be a strip-shaped groove extending in the first direction. Alternatively, the protrusion 22 can be a protrusion, and multiple protrusions can be provided at intervals along the first direction on the mating part 23. In this case, the groove 14 can be a strip-shaped groove or a groove corresponding to the protrusions.

[0070] It is worth mentioning that a third receiving cavity 151 can also be opened inside the frame 15 along the first direction. The third receiving cavity 151 extends through the frame 15 along the first direction. By setting the third receiving cavity 151, the material used in the frame 15 can be reduced, thereby reducing the manufacturing cost of the frame 15 and also reducing the weight of the frame 15.
