The following describes in detail a mobile terminal provided in an embodiment of the present application with reference to the accompanying drawings and specific embodiments and application scenarios thereof.

As shown in fig. 1 to fig. 3, an overall structure schematic diagram of a mobile terminal provided in an embodiment of the present application is provided, where the mobile terminal includes:

the first support frame 11 and the second support frame 12 are slidably connected, that is, the first support frame 11 and the second support frame 12 can slide relative to each other based on the sliding connection position, that is, the second support frame 12 can slide close to or away from the first support frame 11. The mobile terminal includes a contracted state before the sliding, as shown in fig. 1 and 2, a portion of the second support frame 12 is contracted into the first support frame 11; in the unfolded state after the sliding, as shown in fig. 3, the number of portions of the second support frame 12 that leak from the first support frame 11 increases. Preferably, in order to ensure stability during the sliding process, at least two sliding connection positions exist on the mobile terminal. The second supporting frame 12 is provided with a dust removing member at a first target position slidably connected to the first supporting frame 11. Wherein, the dust removal piece realizes the clearance to the foreign matter such as dust on the object of being contacted through the mode of contact. The number of the dust removing pieces can be set according to the requirement, at least one dust removing piece is arranged at each first target position, and here, the number of the first target positions of the second supporting frame 12 is equal to the number of the sliding connection positions of the first supporting frame 11 and the second supporting frame 12 on the mobile terminal.

In order to clean foreign matters such as dust on the sliding connection position of the mobile terminal by the dust removing member, here, the sliding connection position of the mobile terminal is determined as a position of the first support frame 11 in sliding connection with the second support frame 12. By pulling the first support frame 11 or the second support frame 12, the second support frame 12 slides away from the first support frame 11, in this case, the mobile terminal is changed from the contracted state to the expanded state, the dust removing member moves synchronously with the second support frame 12, that is, the dust removing member slides along the second support frame 12 at the position of the first support frame 11, which is in sliding connection with the second support frame 12, and as the dust removing member is attached to the first support frame 11 in the process, foreign matters such as dust at the sliding connection position of the mobile terminal can be cleaned. Specifically, under the condition that the second support frame 12 slides away from the first support frame 11, the dust removing member slides along with the second support frame 12 at a second target position, the dust removing member is attached to the first support frame 11, and the second target position includes a position of the first support frame 11, which is slidably connected to the second support frame 12.

In the embodiment of the present application, a mobile terminal includes: the first support frame 11 and the second support frame 12, the first support frame 11 and the second support frame 12 are connected in a sliding mode, and therefore the first support frame 11 and the second support frame 12 can slide relatively. The first target position of the second support frame 12, which is in sliding connection with the first support frame 11, is provided with a dust removal part, so that the dust removal part for removing dust is located at the sliding connection position of the mobile terminal, and under the condition that the second support frame 12 is far away from the sliding of the first support frame 11, the dust removal part slides along with the second support frame 12 at the second target position, and the dust removal part is attached to the first support frame 11, and because the second target position comprises the position of the first support frame 11, which is in sliding connection with the second support frame 12, the dust removal part can clean foreign matters such as dust at the sliding connection position of the first support frame 11 and the second support frame 12 in the sliding process, and the mobile terminal is cleaned along the sliding direction of the second support frame 12, so that the sliding connection position of the mobile terminal is cleaned.

Optionally, as shown in fig. 4 and 5, a sliding slot 112 is provided at the second target position of the first supporting frame 11, wherein the outer sidewall 121 of the second supporting frame 12 located at the first target position and the dust removing member 13 are located in the sliding slot 112, and when the second supporting frame 12 slides away from the first supporting frame 11, the dust removing member 13 is attached to the bottom of the sliding slot 112.

It should be noted that, with continued reference to fig. 3, each sliding connection position is provided with an inner side wall 111 of the first support frame 11 and an outer side wall 121 of the second support frame 12, the inner side wall 111 and the outer side wall 121 located at the same sliding connection position are oppositely arranged, and the structures of the different sliding connection positions are the same. Here, the upper side of the sidewall of the first support frame 11 is vertically connected to the top surface of the first support frame 11, and the lower side of the sidewall is bent toward the inside of the first support frame 11 to form the sliding groove 112. Preferably, the first side and the second side of the first supporting frame 11, which are opposite to each other, are respectively provided with a sliding slot 112, the two sliding slots 112 are parallel to each other, and the openings of the two sliding slots 112 face each other.

It can be understood that the inner sidewall 111 is located at the second target position of the first support frame 11, and the outer sidewall 121 is located at the first target position of the second support frame 12, so that the dust removing member 13 is disposed on the outer sidewall 121, and in the case that the second support frame 12 slides away from the first support frame 11, the dust removing member 13 is attached to the inner sidewall 111, so that the foreign matters such as dust on the inner sidewall 111 can be pushed out of the mobile terminal along the sliding direction of the second support frame 12. Preferably, in order to ensure the relative sliding between the first support frame 11 and the second support frame 12, a gap is formed between the inner sidewall 111 and the outer sidewall 121 at the same sliding connection position.

In the embodiment of the present application, based on the sliding groove 112 which is simple in structure and easy to process, the sliding connection between the first support frame 11 and the second support frame can be realized, and the complexity of the sliding connection position is reduced.

Optionally, as shown in fig. 5, a dust removing groove 122 is formed on the outer side wall 121, a first portion of the dust removing member 13 is embedded in the dust removing groove 122, a second portion of the dust removing member 13 extends out of the dust removing groove 122, and the second portion of the dust removing member 13 is attached to the bottom of the sliding groove 112 when the second supporting frame 12 slides away from the first supporting frame 11.

It should be noted that the dust removing member 13 and the second supporting frame 12 are independent from each other and can be separately manufactured, so that they can be assembled and disassembled. Here, the dust removing grooves 122 are adapted to the shape of the dust removing members 13, and the number of the dust removing grooves 122 is the same as that of the dust removing members 13, and one dust removing member 13 is correspondingly disposed in each dust removing groove 122. The dust removing member 13 may be in any shape, and only the portion extending out of the dust removing groove 122 is required to be attached to the bottom of the chute. For example, the first portion of the dusting member 13 is rectangular in cross-section, the dusting recess 122 is a rectangular recess, i.e. a recess that is also rectangular in cross-section.

Preferably, the fitting portion of the dust removing member 13 with the bottom of the chute 112 extends from one side wall of the chute 112 to the other side wall, so as to avoid the existence of an uncleanable portion at the bottom of the chute 112. Under the condition that the second supporting frame 12 slides away from the first supporting frame 11, the dust removing piece 13 slides from one end of the sliding groove 112 to the other end, and the dust removing piece 13 is always attached to the bottom of the sliding groove 112 in the sliding process, so that the bottom of the sliding groove 112 is completely cleaned.

In the embodiment of the present application, the dust removing part 13 and the second supporting frame 12 are independent from each other, and the dust removing part 13 is convenient to maintain through assembling and disassembling.

Optionally, with continued reference to fig. 4 and 5, two side walls of the sliding chute 112 are symmetrically provided with limiting rails 113, a guiding direction of the limiting rails 113 is the same as the guiding direction of the sliding chute 112, the dust removing groove 122 is provided with openings 123 facing the two side walls of the sliding chute 112, the dust removing part 13 is provided with limiting posts 131 facing the two side walls of the sliding chute 112, and the limiting posts 131 pass through the openings 123 and are disposed in the limiting rails 113.

It should be noted that, during the relative sliding process of the second support frame 12 and the first support frame 11, the limiting post 131 of the dust removing component 13 will slide in the limiting rail 113, and since the first portion of the dust removing component 13 is embedded in the dust removing groove 122 of the second support frame 12, the limiting rail 113 limits the limiting post 131, and also can limit the second support frame 12, so that the second support frame 12 will not shift in the vertical sliding direction due to the force applied to the outer side wall during the sliding process, that is, the second support frame 12 slides along a straight line during the sliding process.

In the embodiment of the present application, through the cooperation of limiting rail 113 and limiting column 131, in the sliding process of second support frame 12 relative to first support frame 11, the second support frame 12 is restricted in the left-right direction, so that the second support frame slides along a straight line, and the second support frame is prevented from shaking.

Optionally, referring to fig. 6 and 7, the limiting track 113 includes a first strip-shaped track 1131, a first arc-shaped track 1132, a second strip-shaped track 1133, and a second arc-shaped track 1134, which are sequentially connected end to form a ring shape, the first strip-shaped track 1131 is parallel to the second strip-shaped track 1133, and the guiding direction of the first strip-shaped track 1131 is the same as the guiding direction of the sliding chute 112. That is, the guide directions of the slide groove 112 are the first direction and the second direction of fig. 6, and the guide direction of the first bar-shaped track 1131 is also the first direction and the second direction of fig. 6.

Here, referring to fig. 6, when the second support frame slides away from the first support frame 11 (slides in the first direction), the stopper column slides in the first bar-shaped track 1131 near the bottom of the slide groove 112. Referring to fig. 7, when the second support frame slides (slides in the second direction) close to the first support frame 11, the limit posts slide in the second strip-shaped track 1133 away from the bottom of the chute 112, and there is a gap between the second portion of the dust removing member 13 and the bottom of the chute 112.

It should be noted that sliding the second support frame away from the first support frame 11 can switch the mobile terminal from the retracted state to the extended state, and at this time, it is convenient to push foreign matters such as dust on the bottom of the sliding chute 112 out of the mobile terminal. Therefore, in this process, the limiting column slides in the first strip-shaped track 1131 close to the bottom of the sliding chute 112, and the dust removing piece 13 is always attached to the bottom of the sliding chute 112.

Sliding the second support frame close to the first support frame 11 can switch the mobile terminal from the expanded state to the contracted state. At this time, if the dust removing member 13 is adhered to the bottom of the chute 112, foreign matter such as dust on the bottom of the chute 112 is pushed into the mobile terminal. Therefore, in order to avoid this situation, the limiting column slides in the second bar-shaped track 1133 away from the bottom of the sliding slot 112, and the dust removing member 13 keeps a gap with the bottom of the sliding slot 112, so that the dust removing member 13 does not contact with the bottom of the sliding slot 112, and therefore, foreign matters such as dust at the bottom of the sliding slot 112 are not pushed into the mobile terminal. The gap is small and can be determined according to the requirement, for example, the gap can be 1 mm, but is not limited thereto.

It will be appreciated that the dusting member 13 can move in the direction of the vertical chute 112, i.e. towards and away from the bottom of the chute 112. Therefore, the opening 123 of the dust removing groove 122 extends towards the direction of the sliding chute 112, and the limiting column has a certain moving range in the opening 123 and can be close to and far away from the bottom of the sliding chute 112.

In the embodiment of the application, foreign matters such as dust in the mobile terminal can be removed, and meanwhile, the dust can be prevented from being pushed to the inside of the mobile terminal, so that the pollution to the mobile terminal is avoided.

Optionally, with continued reference to fig. 5, the mobile terminal further includes: the elastic pad 14 is arranged in the dust removing groove 122, and under the condition that the limiting column 131 slides in the second strip-shaped track 1133, the elastic pad 14 is in a state of being pressed by the dust removing piece 13.

It should be noted that the elastic pad 14 is an elastic component, and can be pressed and deformed after receiving an external force, and the elastic pad 14 will have a restoring force. Wherein, the elastic pad can be an elastic component made of silica gel or plastic materials. Referring to fig. 7, in the process that the limiting column 131 slides in the second bar-shaped track 1133, the restoring force of the elastic pad 14 always acts on the dust removing part 13 to urge the dust removing part 13 to move along the third direction, and the limiting column 131 of the dust removing part 13 receives the acting force of the second bar-shaped track 1133 to make the dust removing part 13 unable to move along the third direction, so the elastic pad 14 is always in a squeezing state, when the limiting column 131 moves to the second arc-shaped track 1134, the limiting force of the track on the limiting column 131 disappears, and the dust removing part 13 moves along the third direction, and the limiting column 131 moves into the first bar-shaped track 1131.

In this embodiment, when the limiting column 131 slides to the second arc-shaped track 1134 through the second strip-shaped track 1133, the elastic cushion is pushed by the restoring force of the extruded limiting column 131 to the first strip-shaped track 1131, so that the sliding connection position of the mobile terminal can be cleaned conveniently next time.

Optionally, referring to fig. 4 to 8, a limiting unit 15 is disposed in the sliding groove 112, and in the sliding process of the second support frame 12 away from the first support frame 11, the limiting column 131 slides into the first arc-shaped track 1132, and the dust removing part 13 is attached to the limiting unit 15.

It should be noted that the limiting unit 15 does not limit the normal movement of the dust removing part 13, but limits the dust removing part 13 when the dust removing part 13 does not normally move, so as to ensure that the dust removing part 13 can normally move. Here, the normal movement of the dust removing member 13 means that the dust removing member 13 slides in the stopper rail 113 along with the stopper post 131, and the abnormal movement of the dust removing member 13 means all movements except the normal movement. Specifically, the limiting unit 15 may be a protrusion structure disposed at the bottom of the sliding slot 112 and extending toward the opening of the sliding slot 112. Spacing unit 15 is located the one side of keeping away from second arc track 1134 of first arc track 1132 to when spacing post 131 slides to first arc track 1132, dust removal piece 13 is laminated with spacing unit 15 mutually. Here, the shape of the limiting unit 15 is adapted to the shape of the dusting member 13, for example, the cross section of the second part of the dusting member 13 is arc-shaped, and the cross section of the part of the limiting unit 15 facing the dusting member 13 is also arc-shaped. Here, the spacing unit 15 may also guide the dust removing member 13 to move normally.

In this application embodiment, when spacing post 131 removes to first arc track 1132, restrict dust removal piece 13 through spacing unit 15, can guide the slip of spacing post 131 in the track, avoid spacing post 131 roll-off track simultaneously.

Alternatively, referring to fig. 6 and 7, the post may be circular in cross-section, with the inner side of the first arcuate track 1132 being concave toward the first strip track 1131, forming a protrusion 1135 protruding toward the second strip track 1133, with the track width at the location of the protrusion 1135 being less than the diameter of the cross-section of the post.

It should be noted that the protrusion 1135 is recessed from the inner side of the first arc-shaped track 1132 to the first strip-shaped track 1131, and the track width of the position of the protrusion 1135 is smaller than the diameter of the cross section of the spacing post, so that the spacing post can smoothly pass through the protrusion 1135 during the sliding process of the spacing post from the first strip-shaped track 1131 to the second strip-shaped track 1133 via the first arc-shaped track 1132; in the process of sliding the position-limiting post from the second bar track 1133 to the first bar track 1131 via the first arc track 1132, the position-limiting post cannot pass through the protrusion 1135. Therefore, when the limiting column circularly slides in the annular limiting track, the limiting column can only slide along one direction.

In this embodiment, based on the restriction of protruding portion 1135 for when spacing post slides in annular spacing track inner loop, can only slide along a direction, when avoiding the second carriage to be close to first carriage and slide, spacing post slides in first bar track 1131, causes the circumstances emergence of dust propelling movement to mobile terminal inside.

Alternatively, referring to fig. 9 and 10, the dust removing member 13 includes:

the dust removing part comprises a dust removing part body 132, wherein a through hole 133 is formed in the dust removing part body 132;

the upright column 134 penetrating through the through hole 133, and the part of the upright column 134 that leaks outside the dust removing body 132 is a limiting column.

It should be noted that the through hole 133 may be a square through hole, but is not limited thereto. When the post 134 is inserted into the through hole 133, the through hole 133 is fitted to the post 134, and the post 134 cannot rotate in the through hole 133. Preferably, the end of the post 134 is cylindrical to facilitate its sliding within the retaining track.

In the embodiment of the present application, the dust removing part 13 is composed of the dust removing part body 132 provided with the through hole and the upright column 134, and the two parts are independent from each other and can be independently processed and manufactured, so that the maintenance of the dust removing part 13 can be realized through the assembly and the disassembly, and the maintenance cost is reduced.

Optionally, the dust removing part is an elastic part, and the dust removing part attached to the first support frame is in a compressed state.

It should be noted that the elastic member may be pressed and deformed after receiving an external force, and at this time, will have a restoring force. Preferably, the dust removing member may be an elastic member made of silicon gel or plastic, but is not limited thereto. Here, if the dust removing part is not an elastic component, in the relative sliding process of the first supporting frame and the second supporting frame, because the dust removing part is attached to the first supporting frame, a large friction force is generated, and further the relative sliding is prevented, and a user needs to use a larger force to enable the first supporting frame and the second supporting frame to slide relatively. Therefore, the dust removing part selects the elastic part, and the force of a user in sliding the first supporting frame and the second supporting frame is reduced while the dust removing part is ensured to be cleaned.

In the embodiment of the application, when clearing up mobile terminal sliding connection position, utilize the elasticity characteristic of dust removal piece, avoid the frictional force between dust removal piece and the first carriage too big to the user can easily slide first carriage and second carriage.

Optionally, referring to the mobile terminal exploded view shown in fig. 11, the mobile terminal further includes: a reel 16 provided on the second support frame 12, and a flexible screen 17 partially surrounding the reel 16. When the second support frame 12 slides away from the first support frame 11, the flexible screen 17 gradually unwinds around the reel 16; in the case where the second support frame 12 slides close to the first support frame 11, the number of portions of the flexible screen 17 wound around the reel 16 increases. Of course, as shown in fig. 11, the mobile terminal device may further include a battery 18, a main board 19, a camera 20, an installation box 21, and the like.

In the embodiment of the application, the cleaning of foreign matters such as dust at the sliding connection position between the first supporting frame and the second supporting frame can be realized on the mobile terminal with the curled screen.
