In one embodiment, the frame cover structure 101 includes a thin outer shell 102, and an outer skin 102a of the thin outer shell 102 covers a surface of a gap G at the joint of the frame tube 110 a. Referring to fig. 1, 2A and 3, the thin shell 102 is disposed on the lower tube 113 of the frame tube 110a, and the thin shell 102 covers a joint portion of the frame tube 110a between the power element 170 and the driving device 180.

The frame cover structure 101 of the present embodiment is not limited to cover the power element 170, and can directly cover the lower tube 113 without the power element 170. When the lower tube 113 of the frame 110 is provided with a power element 170, the thin-layer shell 102 covers the outer surface of the power element 170 to protect the substrate 174 and the metal contact 176 electrically connected between the power element 170 and the driving device 180, and to prevent silt from splashing into the gap G between the power element 170 and the driving device 180. In addition, the thin shell 102 covers the outer surface of the lower tube 113 and extends from the lower end of the power element 170 to the side edge of the driving device 180, so as to change the gap G between the power element 170 and the driving device 180 to a lower position. As shown in fig. 3, 2A and 1, the changed gap position P is lower than the gap position between the original pipes (i.e. the joint portion between the power element 170 and the driving device 180), so that the silt cannot be splashed into the original gap G.

As can be seen from the above description, the thin-layer housing 102 of the present embodiment can be fixed on the power supply housing 172 of the power supply element 170, and not only has the anti-collision function to prevent the element from being damaged, but also can form a mud stop structure on the lower pipe 113. Moreover, the outer shape of the thin shell 102 matches with the outer shapes of the lower tube 113 of the frame tube 110a and the driving device protection shell 115, so that the thin shell meets the sensory and aesthetic requirements of people in appearance, has a mud blocking function in structure, and has the practicability of water resistance and dust resistance.

In addition, the power supply housing 172 may be a hard material, and the thin housing 102 may be a flexible material or a composite material having both hard and soft materials, for example, the thin housing 102 and the power supply housing 172 are injected in two materials, and the thin housing 102 is further made of two materials with different hardness, for example, the thin housing 102 may be injected in two materials of plastic and rubber, but the present invention is not limited thereto. The hard material is, for example, plastic or metal, and the soft material is, for example, rubber or a soft flexible material other than rubber. In addition, the thin layer housing 102 can be fastened to the power supply housing 172 and can be detached to be an independent component, and the thin layer housing 102 and the power supply housing 172 are respectively covered on different parts of the pipe or different pipes.

Referring to fig. 3, the thin shell 102 includes a first part 1021 and a second part 1022, the first part 1021 is made of a hard material such as plastic, the second part 1022 is made of a soft material such as rubber, the first part 1021 can be overlapped with the power shell 172 and can be fastened with the tenon 105 (referring to fig. 4, the number of the tenon 105 can be one or more) on the inner surface layer 102b passing through the fastening hole of the power shell 172, so that the first part 1021 is fixed on the power shell 172. The second part 1022 extends from the lower end of the first part 1021 to the driving device protecting case 115 to cover the side of the driving device protecting case 115.

The thin-layer housing 102 (i.e., the second component 1022) made of a flexible material covers the gap between the power element 170 and the driving device 180, so that the thin-layer housing 102 can be deformed appropriately during the process of mounting and dismounting the power element 170.

Referring to fig. 2A, the tubular battery 171 is shown in a locked position, wherein the tubular battery 171 is locked by the power locking member 173 and is received in the mounting groove 113S of the lower tubular member 113. Referring to fig. 2B, it is shown that during the operation of removing the tubular battery 171 from the mounting groove 113S of the lower tube 113, when the power locking member 173 is unlocked (not shown), one end of the tubular battery 171 contacting the base plate 174 is used as a fulcrum to axially rotate (as indicated by an arrow R) the tubular battery 171 including the power housing 172, and at this time, the thin shell 102 covering the joint between the power element 170 of the frame tube 110a and the driving device 180 is deformed correspondingly by the rotation operation of axially detaching the tubular battery 171 from the lower tube 113, especially the soft material portion of the second part 1022 of the thin shell 102, so as to facilitate the removal of the tubular battery 171 from the lower tube 113.

Referring to fig. 3, an exploded view of the frame cover structure 101, the power element 170 and the frame tube 110a is shown. Since the driving device 180 is disposed at the five-way position of the frame 110 (see fig. 1), the driving device 180 can be accommodated in the driving device protection housing 115 for protection by combining the driving device protection housing 115 and the frame tube 110a into a whole in a locking manner. The joint between the power source 170 and the driving device 180 has a gap G, which allows the tubular battery 171 to pivot from the base plate 174 at its lower end without mechanical obstruction or interference, so as to maintain a sufficient gap to reserve the space required for the rotation of the tubular battery 171, but the gap G is not kept to prevent mud from splashing to the gap G. Therefore, in this embodiment, it is necessary to cover the gap G at the joint between the power element 170 and the driving device 180 with the thin shell 102 made of flexible material, and the gap G is not completely closed by a sealing means, but the position of the gap between the original pipes is changed (e.g. the position of the gap is reduced), so that the present invention has practicability.

Referring to fig. 2A and 4, the frame cover structure 101 may further include a fastener 103, wherein the fastener 103 is disposed on the inner surface layer 102b of the thin-layer shell 102, and the other fastener 104 is disposed on the frame tube 110a at a position corresponding to the fastener 103. The

fasteners

103, 104 are, for example, magnets or male and female fasteners other than magnets, so as to facilitate the quick positioning and precise combination of the thin-layer housing 102 and the frame tube 110a at corresponding positions. In this embodiment, the inner surface layer 102b of the thin shell 102 can be coupled to the frame tube 110a by

fasteners

103, 104, such as male and female fasteners, which are attracted or interference-fitted by magnets (or magnetic conductive elements, magnetic elements, etc.) with attractive polarities, of the thin shell 102, and fixed to the outer surface of the lower tube 113 (or the driving device protection housing 115). The number of the

fasteners

103, 104 may be one or a combination of pairs to allow the thin shell 102 and the frame tube 110a to be firmly coupled.
