These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Electric scooters are a lightweight, environmentally friendly, and economical means of transportation for short distances, widely used in urban commuting and shared mobility. To improve riding comfort, modern electric scooters typically incorporate shock absorbers in the front fork assembly to reduce vibrations during riding.

[0048] However, electric scooters typically employ an independent shock absorption design on both sides of the fork assembly. This means that the shock absorbers on both sides of the fork assembly are independently installed within the fork assembly. During riding, the movement trajectories of the shock absorbers on both sides of the fork assembly are often inconsistent, which can lead to problems such as steering wobble, uneven bushing wear, and frame fatigue in electric scooters. This, in turn, affects the handling stability, safety, and lifespan of the electric scooter.

[0049] Specifically, because the two shock absorbers are independently installed, differences in assembly precision arise. Furthermore, due to wear and manufacturing tolerances, the two shock absorbers will exhibit inconsistent motion trajectories after the electric scooter experiences road impacts. This inconsistent motion trajectory generates asymmetrical torques when the electric scooter turns, causing steering wobbling, affecting handling stability and posing a safety hazard. The inconsistent motion trajectory also results in uneven force on the shock absorber bushings, potentially leading to severe wear on one side of the bushing, thus affecting shock absorber performance and consequently impacting the electric scooter's safety and lifespan. Finally, the inconsistent motion trajectory causes the frame to endure asymmetrical alternating stress over time, making welded joints and connections prone to cracking, reducing frame strength, causing frame fatigue, and increasing the risk of frame breakage. This ultimately affects the electric scooter's safety and service life.

[0050] Based on the above-mentioned situation and problems, this application provides a shock absorber linkage structure. This shock absorber linkage structure is connected between two shock absorbers and can drive the shock absorbers on both sides of the front fork assembly to move synchronously, thereby keeping the movement trajectory of the shock absorbers consistent, which can improve the safety, handling stability and service life of the electric scooter.

[0051] Based on the above-mentioned shock absorber linkage structure, this application embodiment also provides a front fork assembly, on which the front wheel of an electric scooter can be mounted, and the steering of the electric scooter can be controlled through the front fork assembly.

[0052] The aforementioned shock absorber linkage structure or front fork assembly can be applied to electric scooters. In other possible cases, the shock absorber linkage structure or front fork assembly can also be applied to other scooters (e.g., without a power system). Therefore, this application embodiment also provides a scooter that has excellent handling and safety performance based on the shock absorber linkage structure or front fork assembly, and the service life of the scooter will also be extended to a certain extent.

[0053] Figure 1 A schematic diagram of a front fork assembly according to an embodiment of this application is shown; Figure 2 A schematic diagram of a front fork assembly with the outer trim panel removed, provided according to an embodiment of this application, is shown.

[0054] In the embodiments of this application, please refer to Figure 1 and Figure 2 The scooter includes a frame (not shown), a seat tube 10, and a fork assembly 20, the seat tube 10 being connected to the fork assembly 20.

[0055] The frame is the load-bearing component of the scooter, and necessary features such as seats, standing positions, or storage compartments can be installed on the frame. The stem 10 is rotatably connected to the front of the frame, and the scooter can be steered by rotating the stem 10. Typically, to simplify operation, a steering handle or similar structure can be installed on the top of the stem 10.

[0056] Understandably, the front fork assembly 20 is used to mount the front wheel of the scooter. By controlling the rotation of the seat tube 10, the front fork assembly 20 and the front wheel can be driven to rotate, thereby driving the scooter to turn as a whole.

[0057] The fork assembly 20 includes a first shock absorber 21 and a second shock absorber 22. The seat tube 10 is connected to the first shock absorber 21 and the second shock absorber 22. For this purpose, the seat tube 10 can form a first connecting arm 11 and a second connecting arm 12 on both sides respectively. The first connecting arm 11 is used to connect with the first shock absorber 21, and the second connecting arm 12 is used to connect with the second shock absorber 22. The front wheel can be mounted on the first shock absorber 21 and the second shock absorber 22.

[0058] Therefore, it can be understood that by controlling the rotation of the riser tube 10, the first shock absorber 21 and the second shock absorber 22 can be driven to rotate. Since the front wheels are mounted on the first shock absorber 21 and the second shock absorber 22, the front wheels will rotate with the first shock absorber 21 and the second shock absorber 22, thereby realizing the steering operation of the whole vehicle.

[0059] During the operation of the scooter, the first shock absorber 21 and the second shock absorber 22 can alleviate the vibration caused by uneven road surface, enabling the scooter to run smoothly on the road surface, thereby improving the running comfort of the scooter.

[0060] Furthermore, as can be seen from the following embodiments, the front fork assembly 20 in this application embodiment may also include a shock absorber linkage structure. Based on the setting of the shock absorber linkage structure, the movement trajectory of the first shock absorber 21 and the second shock absorber 22 can be kept consistent, thereby enabling the scooter to have excellent handling and safety performance, and the service life of the scooter will also be extended to a certain extent.

[0061] It should be noted that, in order to improve the left-right symmetry of the scooter, the first shock absorber 21 and the second shock absorber 22 can have the same structure.

[0062] In some embodiments, please refer to Figure 3 and Figure 4 The central axis of the first shock absorber 21 extends along the first direction, the central axis of the second shock absorber 22 extends along the second direction, and the central axis of the riser 10 extends along the third direction. The third direction is offset from the first direction toward the frame by a predetermined angle, and the third direction is offset from the second direction toward the frame by a predetermined angle.

[0063] It is understandable that the first shock absorber 21 and the second shock absorber 22 can be located in the same plane, making the first center axis parallel to the second center axis. The aforementioned arrangement of the center axes of the riser 10, the first shock absorber 21, and the second shock absorber 22 allows the riser 10 to deviate from the frame by a predetermined angle. When shock absorption is required, this angle deviation can result in a greater drag distance, thereby making the scooter more stable during operation.

[0064] The aforementioned predetermined angle can be set according to requirements. For example, in some specific embodiments, the predetermined angle is 5° to 10°. In specific designs, the preset angle can be 5°, 6°, 7°, 8°, 9°, 10°, or any combination thereof.

[0065] In some embodiments, please refer to Figure 2 The fork assembly 20 includes a first shock absorber 21, a second shock absorber 22, and a shock absorber linkage structure 23, which is connected between the first shock absorber 21 and the second shock absorber 22.

[0066] As can be seen from the following embodiments, the shock absorber linkage structure 23 may include a linkage fastener 100, which is used to connect with the first shock absorber 21 and the second shock absorber 22, thereby enabling the first shock absorber 21 and the second shock absorber 22 to be connected as one unit, thereby achieving uniformity in their motion trajectory.

[0067] The front fork assembly 20, based on the shock absorber linkage structure 23, can achieve the unification of the first shock absorber 21 and the second shock absorber 22 in the motion trajectory, thereby improving the safety, handling stability and service life of the electric scooter.

[0068] In some embodiments, please refer to Figure 2 The linkage fastener 100 includes a first connecting part 110 and a second connecting part 120. The first shock absorber 21 includes a first shock-absorbing sleeve 21a and a first shock-absorbing component 21b disposed within the first shock-absorbing sleeve 21a. The second shock absorber 22 includes a second shock-absorbing sleeve 22a and a second shock-absorbing component 22b disposed within the second shock-absorbing sleeve 22a. A first shock-absorbing connecting part 21a1 is provided on the first shock-absorbing sleeve 21a, and a second shock-absorbing connecting part 22a1 is provided on the second shock-absorbing sleeve 22a. The first connecting part 110 is connected to the first shock-absorbing connecting part 21a1, and the second connecting part 120 is connected to the second shock-absorbing connecting part 22a1.

[0069] Specifically, the first damping connection 21a1 can be located on the side of the first damping sleeve 21a away from the frame. This first damping connection 21a1 can be connected to the outer wall of the first damping sleeve 21a; for example, it can extend from the outer wall of the first damping sleeve 21a, thereby facilitating a connection between the first damping connection 21a1 and the first connection 110. The connection method can be welding, bolting, or other similar methods. The second damping connection 22a1 can be located on the side of the second damping sleeve 22a away from the frame. This second damping connection 22a1 can be connected to the outer wall of the second damping sleeve 22a; for example, it can extend from the outer wall of the second damping sleeve 22a, thereby facilitating a connection between the second damping connection 22a1 and the second connection 120. The connection method can be welding, bolting, or other similar methods.

[0070] The first damping sleeve 21a and the second damping sleeve 22a can be made of metal material and have cavities inside. The first damping component 21b and the second damping component 22b can be housed in the corresponding cavities.

[0071] The above embodiments describe the relevant structures for the linkage fastener 100 to be connected with the second shock absorber 22. Other components of the linkage fastener 100 can be referred to in the following embodiments.

[0072] In some embodiments, please refer to Figure 2 The linkage fastener 100 is provided with a reinforcing member 200, which is used to improve the structural strength of the linkage fastener 100.

[0073] In some embodiments, please refer to Figure 1 and Figure 2 The shock absorber linkage structure also includes an outer trim panel 300, a first reinforcing connection part 21a2 is provided on the first shock absorber sleeve 21a, and a second reinforcing connection part 22a2 is provided on the second shock absorber sleeve 22a. The outer trim panel 300 is connected to at least one of the first reinforcing connection part 21a2 and the second reinforcing connection part 22a2.

[0074] The main function of the exterior trim panel 300 is to enhance the structural strength of the aforementioned linkage fastener 100. Specifically, the exterior trim panel 300, the linkage fastener 100, and the reinforcing member 200 can be integrated into one unit, preventing the linkage fastener 100 from deforming and losing its function of connecting the first shock absorber 21 and the second shock absorber 22. In addition, the exterior trim panel 300 can also serve a decorative purpose.

[0075] It should be understood that the first reinforcing connection 21a2 can be separated from the aforementioned first damping connection 21a1, and the second reinforcing connection 22a2 can be separated from the aforementioned second damping connection 22a1.

[0076] The first reinforcing connection 21a2 can extend from the outer wall of the first damping sleeve 21a, thereby facilitating the connection between the first reinforcing connection 21a2 and the outer trim panel 300; the second reinforcing connection 22a2 can extend from the outer wall of the second damping sleeve 22a, thereby facilitating the connection between the second reinforcing connection 22a2 and the outer trim panel 300.

[0077] As can be seen from the following embodiments, the first reinforcing connection part 21a2 is the structure in the first shock absorber 21 used to connect with the outer trim panel 300, and the second reinforcing connection part 22a2 is the structure in the second shock absorber 22 used to connect with the outer trim panel 300. In order to improve the connection strength, the outer trim panel 300 can also be connected to the above-mentioned linkage fastener 100.

[0078] The above embodiments describe the relevant structures for connecting the exterior panel 300 with the second shock absorber 22. Other components and functions of the exterior panel 300 can be found in the following embodiments.

[0079] In some embodiments, please refer to Figures 2 to 4 To facilitate the installation of the front wheel, the first shock absorber sleeve 21a further includes a first extension arm 21a3, and the second shock absorber sleeve 22a further includes a second extension arm 22a3. The first extension arm 21a3 is provided with a first front wheel mounting hole 21a31, and the second extension arm 22a3 is provided with a second front wheel mounting hole 22a31. The first front wheel mounting hole 21a31 and the second front wheel mounting hole 22a31 are used to install the front wheel of the scooter.

[0080] During assembly, the axle of the front wheel can be rotatably installed in the first front wheel mounting hole 21a31 and the second front wheel mounting hole 22a31. To improve the running stability of the front wheel, bearings and other structures can also be installed on the outer periphery of the front wheel axle.

[0081] In some embodiments, please refer to Figures 2 to 4 At least one of the first extension arm 21a3 and the second extension arm 22a3 is provided with a brake mounting portion 21a32, which is used for detachably connecting a brake. For the sake of simplicity, the following embodiment will be described using the example of providing a brake mounting portion 21a32 on the first extension arm 21a3.

[0082] It should be noted that the function of the brake is to brake the front wheels. This application does not limit the specific type of brake. The brake can be a hydraulic disc brake or a cable disc brake. The specific structure of a hydraulic disc brake or a cable disc brake can be referred to relevant technologies.

[0083] The brake can be installed on the brake mounting part 21a32 using fasteners such as screws, thereby enabling the brake to be detachably connected, which facilitates the maintenance or replacement of the brake.

[0084] Specifically, the brake mounting portion 21a32 can be connected to the first extension arm 21a3, or the brake mounting portion 21a32 can be integrally formed with the first extension arm 21a3. The brake mounting portion 21a32 has a mounting port for mounting a brake, and the brake can be confined in the mounting port.

[0085] It should be understood that the brake mounting part 21a32 can be connected to the part in the first extension arm 21a3 used to form the first front wheel mounting hole 21a31. At this time, the front wheel and the brake can be relatively concentratedly connected to the same part of the first extension arm 21a3, so that the brake and the front wheel can interact with each other and the internal stress generated by them can cancel each other out, thereby improving the structural strength of the first extension arm 21a3 and the first shock absorber sleeve 21a.

[0086] It should be noted that the aforementioned first damping connection 21a1, first reinforcing connection 21a2, and first extension arm 21a3 are the parts in the first damping sleeve 21a used for connecting with other structures, and the aforementioned second damping connection 22a1, second reinforcing connection 22a2, and second extension arm 22a3 are the parts in the second damping sleeve 22a used for connecting with other structures. This application does not limit the specific structure and quantity of these parts. For example, in... Figures 2 to 3 In the example shown, the first shock-absorbing connection 21a1, the first extension arm 21a3, the second shock-absorbing connection 22a1, and the second extension arm 22a3 are all provided as one, while the number of the first reinforcing connection 21a2 and the second reinforcing connection 22a2 is two.

[0087] Figure 3 A schematic diagram of the structure of a first shock absorber 21 provided according to an embodiment of this application is shown; Figure 4 An exploded schematic diagram of a first shock absorber 21 provided according to an embodiment of this application is shown.

[0088] In some embodiments, please refer to Figure 3 and Figure 4 The first damping component 21b and the second damping component 22b may include a fixed rod 21b1, a movable rod 21b2, and an elastic element 21b3 disposed between the two. For the sake of simplicity, the following embodiment uses the first damping component 21b as an example for illustration, and the second damping component 22b can be configured with reference to the first damping component 21b.

[0089] The fixed rod 21b1 can be fixedly installed in the first damping sleeve 21a, and the movable rod 21b2 can move in the first damping sleeve 21a. The movable rod 21b2 is sleeved on the outer periphery of the fixed rod 21b1, and the elastic element 21b3 is connected between the fixed rod 21b1 and the movable rod 21b2.

[0090] The aforementioned first damping component 21b can achieve a damping effect by moving the movable rod 21b2 within the first damping sleeve 21a.

[0091] In some embodiments, please refer to Figure 4 A sealing component 21b4 is also provided on the outer periphery of the movable rod 21b2. The sealing component 21b4 can be located on the top of the first shock-absorbing sleeve 21a. The sealing component 21b4 can form a seal between the movable rod 21b2 and the first shock-absorbing sleeve 21a without hindering the movement of the movable rod 21b2.

[0092] In some specific embodiments, the sealing assembly 21b4 may include a sealing ring, a sealing gasket, etc.

[0093] In the embodiments of this application, please refer to Figure 2 The shock absorber linkage structure includes a linkage fastener 100, which is connected between the first shock absorber 21 and the second shock absorber 22 of the front fork assembly 20 to enable the first shock absorber 21 and the second shock absorber 22 to operate synchronously.

[0094] The shock absorber linkage structure in this embodiment is based on the linkage fastener 100, which can unify the movement trajectory of the first shock absorber 21 and the second shock absorber 22, thereby improving the safety, handling stability and service life of the electric scooter.

[0095] In some embodiments, please refer to Figure 2 The linkage fastener 100 includes a first connecting part 110, a second connecting part 120 and a third connecting part 130. The first connecting part 110 is connected to the first shock absorber 21, the second connecting part 120 is connected to the second shock absorber 22, and the third connecting part 130 is connected to the first connecting part 110 and the second connecting part 120.

[0096] The specific structure of the linkage fastener 100 is not limited. For example, in some embodiments, the linkage fastener 100 can be a rod-shaped structure extending from one end to the other. In this case, the first connecting part 110, the second connecting part 120 and the third connecting part 130 can be constructed as a tubular structure, thereby simplifying the structural composition of the linkage fastener 100.

[0097] The first connecting part 110, the second connecting part 120 and the third connecting part 130 can be integrally formed. For example, in some specific embodiments, the first connecting part 110, the second connecting part 120 and the third connecting part 130 can be formed by bending the same pipe. In other specific embodiments, the first connecting part 110, the second connecting part 120 and the third connecting part 130 can be manufactured by injection molding.

[0098] In some embodiments, to reduce the weight of the linkage fastener 100, the linkage fastener 100 may have a hollow structure. Regarding material selection, the linkage fastener 100 may be made of a high-strength metal material, such as stainless steel.

[0099] In some embodiments, please refer to Figure 2 The first connecting part 110 is provided with a connecting plate 140 at its end, and / or the second connecting part 120 is provided with a connecting plate 140 at its end, and the connecting plate 140 is provided with a connecting hole.

[0100] The connecting plate 140 is a flat plate with a smooth surface, which allows it to form a large-area contact with the first shock absorber 21 or the second shock absorber 22, thereby forming a reliable connection. For example, taking the first shock-absorbing connecting part 21a1 provided on the first shock-absorbing sleeve 21a as an example, the first shock-absorbing connecting part 21a1 can also be constructed as a flat plate, thereby allowing the first connecting part 110 to form a surface contact with the first shock-absorbing connecting part 21a1, thereby forming a reliable connection between the two.

[0101] The connection hole can be a threaded hole, and the connection can be completed by passing a screw or bolt through the connecting plate 140 and the first shock-absorbing connection part 21a1.

[0102] In some embodiments, please refer to Figure 2 The third connecting part 130 is tilted away from the upright 10.

[0103] This can be understood as follows: the first connecting part 110 and the second connecting part 120 can be parallel to the central axis of the riser 10, and the third connecting part 130 is raised away from the riser 10 with the riser 10 as the reference, so that the third connecting part 130 can face the outside of the scooter, which facilitates secondary processing of the third connecting part 130. For example, a handhold part 131 can be formed on the third connecting part 130, so that the user can apply force to the handhold part 131 to move the scooter.

[0104] In some embodiments, please refer to Figure 2 The first connecting part 110 and the third connecting part 130 form a first inflection point 111, and the second connecting part 120 and the third connecting part 130 form a second inflection point 121. The first inflection point 111 is close to the first shock absorber 21, and the second inflection point 121 is close to the second shock absorber 22.

[0105] Therefore, by setting the first inflection point 111 close to the first shock absorber 21 and the second inflection point 121 close to the second shock absorber 22, the obstruction of the riser tube 10 can be avoided, thus making it easier for users to ride the scooter.

[0106] Of course, it should be noted that the positions of the first inflection point 111 and the second inflection point 121 can also be changed. For example, the first inflection point 111 can be moved away from the first shock absorber 21, and the second inflection point 121 can be moved away from the second shock absorber 22, thereby increasing the wrapping space of the linkage fastener 100, which makes it easier to connect the reinforcing member 200, the outer trim panel 300, etc. in the following embodiments on the linkage fastener 100.

[0107] In some embodiments, the first connecting portion 110 and the second connecting portion 120 are symmetrically arranged on both sides of the third connecting portion 130. The linkage fastener 100 has a symmetrical structure, which can balance the stress on both sides of the scooter, thereby improving the stability of the scooter. In addition, adopting a symmetrical structure can also reduce the manufacturing difficulty of the linkage fastener 100 to a certain extent.

[0108] In some embodiments, the linkage fastener 100 forms a locking ring. For example, the aforementioned first connecting portion 110, second connecting portion 120, and third connecting portion 130 can form a ring structure or a semi-ring structure, thereby enabling the linkage fastener 100 to work with locks to lock the scooter to a guardrail, frame, or other structure. This linkage fastener 100 facilitates the locking of the scooter.

[0109] In some embodiments, please refer to Figure 2 The linkage fastener 100 is provided with a reinforcing member 200, which is connected between the first connecting part 110 and the second connecting part 120.

[0110] The reinforcing member 200 can enhance the structural strength of the linkage fastener 100 and prevent the linkage fastener 100 from being damaged due to excessive force.

[0111] In some specific embodiments, please refer to Figure 2 The reinforcing member 200 includes a first reinforcing section 210, a second reinforcing section 220, and a third reinforcing section 230 connected between the first reinforcing section 210 and the second reinforcing section 220. The first reinforcing section 210 is connected to the first connecting portion 110, and the second reinforcing section 220 is connected to the second connecting portion 120.

[0112] Therefore, for the linkage fastener 100, its first connecting part 110 can be strengthened by the first reinforcing section 210, and its second connecting part 120 can be strengthened by the second reinforcing section 220, thereby improving the structural strength of the linkage fastener 100.

[0113] As mentioned above, the first reinforcing section 210 can be connected at the first inflection point 111, and the second reinforcing section 220 can be connected at the second inflection point 121. This can improve the structural strength of the linkage fastener 100 at the first inflection point 111 and the second inflection point 121, and prevent the linkage fastener 100 from bending at the first inflection point 111 and the second inflection point 121.

[0114] Similar to the aforementioned linkage fastener 100, the reinforcing member 200 can also be designed as a symmetrical structure, such as the first reinforcing section 210 and the second reinforcing section 220 being symmetrically arranged on both sides of the third reinforcing section 230.

[0115] In addition, to improve structural strength and simplify manufacturing process, the aforementioned linkage fastener 100 and reinforcing member 200 can be designed as an integrated structure. For example, the linkage fastener 100 and reinforcing member 200 can be manufactured by integral molding.

[0116] In some embodiments, please refer to Figure 2 The shock absorber linkage structure also includes an outer trim panel 300 that is detachably connected to the linkage fastener 100 and / or the reinforcement 200, the outer trim panel 300 covering at least a portion of the linkage fastener 100.

[0117] As mentioned above, the main function of the outer trim panel 300 is to enhance the structural strength of the linkage fastener 100. Here, by setting the outer trim panel 300 to cover part of the linkage fastener 100, it can prevent external impact forces from acting on the linkage fastener 100 and provide good protection for the linkage fastener 100.

[0118] In addition, the outer trim panel 300 can be further processed to give it other functions. For example, in some embodiments, the outer trim panel 300 is provided with a decorative part or a mounting part 310. The decorative part can meet the user's needs for different appearances. The decorative part can be set according to different needs. The mounting part 310 is used to connect the decorative structure or the functional structure. The decorative structure can be set according to different needs, and the functional structure can also be set according to different needs.

[0119] For example, in terms of decorative parts and decorative structures, decorative parts and decorative structures may include decorative parts that can emit light or decorative parts with different shapes; in terms of functional structures, functional structures may be box structures with storage functions or display devices that can display relevant information about the scooter.

[0120] In some embodiments, an exterior panel mounting portion 231 is provided on the third reinforcing section 230, and at least a portion of the exterior panel 300 is connected to the reinforcing member 200 through the exterior panel mounting portion 231. The exterior panel mounting portion 231 may be a mounting hole or the like provided on the third reinforcing section 230. The mounting hole may be located in the middle part of the third reinforcing section 230, and the number of mounting holes may be set according to requirements.

[0121] In some embodiments, the exterior panel 300 has a shape adapted to the riser 10, the first shock absorber 21 or the second shock absorber 22 of the electric scooter, and a reinforcing member 200 is provided on the linkage fastener 100, and the exterior panel 300 is connected to the reinforcing member 200.

[0122] By providing a reinforcing member 200 between the linkage fastener 100 and the outer trim panel 300, it is possible to avoid directly connecting the outer trim panel 300 to the linkage fastener 100, thereby preventing unnecessary impact and internal stress on the linkage fastener 100.

[0123] The reinforcing member 200 can be connected between the first connecting part 110 and the second connecting part 120. The specific structure of the reinforcing member 200 can adopt a curved flat structure, thereby achieving a reliable connection between the outer trim panel 300 and the reinforcing member 200.

[0124] As an example, the exterior panel 300 may include a housing that can be located at the front of the scooter and serves to block airflow. Furthermore, structures such as lighting fixtures can be integrated into this housing.

[0125] The enclosure has certain structural strength requirements. In some embodiments, the enclosure can be made of impact-resistant polymer materials. Furthermore, the enclosure can be designed as a multi-layered structure; for example, it can be a three-layered structure, with the middle layer made of metal and the inner and outer layers made of polymer materials.
