[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-2 , Figure 1 is a structural diagram of a mobile phone case for cleaning a lens according to an embodiment of the present invention; Figure 2 The sectional view of the wiping assembly of the mobile phone case for cleaning the lens according to one embodiment of the present invention is shown in FIG. The mobile phone case for cleaning the lens comprises: a housing 1 and a wiping assembly 3 .

[0023] The housing 1 is provided with a guide groove 11; the rear lens of the mobile phone is located in the guide groove 11; the inner side wall of the guide groove 11 is evenly provided with a plurality of tooth grooves 111; the wiping assembly 3 includes a slider 31, a transmission shaft 33, a wiping component 35 and a transmission gear 37; an opening 311 is provided at the bottom of the slider 31, and the opening 311 is provided with a first pulley group 313; the first end of the transmission shaft 33 passes through the opening 311 and is movably arranged in the slider, and the side surface of the transmission shaft 33 is in contact with the first pulley group 313; the second end of the transmission shaft 33 is fixed with the wiping component 35; the transmission gear 37 is sleeved between the slider 31 and the first pulley group 313; The transmission shaft 33 between the wiping components 35 is provided with a plurality of gear teeth evenly distributed on the outer surface of the transmission gear 37; when the slider 31 is slidably arranged on the guide groove 11, the wiping component 35 and the transmission gear 37 are located in the guide groove 11, and the gear teeth on the transmission gear 37 are meshed and connected with the tooth groove 111 on the guide groove 11; when the slider 31 slides along the guide groove 11, the transmission shaft 33 moves with the sliding of the slider 31, and drives the wiping component 35 to move, and at the same time, the moving transmission shaft 33 rotates with the meshing of the gear teeth and the tooth groove 111, thereby driving the wiping component 35 to rotate.

[0024] In this embodiment, when the user needs to clean the rear camera of the mobile phone, the user can slide the slider 31 from the end of the guide groove 11 away from the rear camera of the mobile phone to the end close to the rear camera of the mobile phone, thereby driving the first pulley group 313 of the opening 311 of the slider 31 to slide, and because the transmission shaft 33 abuts against the first pulley group 313, the transmission shaft 33 moves with the sliding of the first pulley group 313, thereby driving the wiping component 35 to move, and when the slider 31 slides along the guide groove 11 to the position corresponding to the rear camera of the mobile phone When the wiping member 35 is in position, the wiping member 35 abuts against the rear camera of the mobile phone, so that the rear camera of the mobile phone is wiped by the wiping member 35; further, during the movement of the transmission shaft 33, the transmission gear 37 sleeved on the transmission shaft 33 meshes and rotates with the tooth groove 111 on the guide groove 11, so that the transmission shaft 33 rotates during the movement, thereby driving the wiping member 35 to rotate, so that the wiping member 35 rotates while wiping the rear camera of the mobile phone, so as to better clean the tiny dust attached to the rear camera of the mobile phone, so as to improve the wiping effect. When the user does not need to clean the rear camera of the mobile phone, the user can slide the slider 31 along the guide groove 11 to the end of the guide groove 11 away from the rear camera of the mobile phone to prevent the slider 31 from blocking the camera of the mobile phone, so that the rear camera of the mobile phone can smoothly take pictures.

[0025] Compared with the prior art, the mobile phone case for cleaning the lens of the present invention slides the slider 31 on the guide groove 11, so that the transmission shaft 33 moves with the sliding of the slider 31, thereby driving the wiping component 35 to move, and then the wiping component 35 contacts the rear camera of the mobile phone, so that the wiping component 35 acts on the rear camera of the mobile phone to wipe the rear camera of the mobile phone. At the same time, the moving transmission shaft 33 rotates with the meshing of the gear and the tooth groove 111, and then drives the wiping component 35 to rotate, so as to better clean the tiny dust attached to the rear camera of the mobile phone, so as to improve the wiping effect, and during the cleaning process, the user only needs to slide the slider 31, which is convenient for the user to use at any time, and there is no need to use other additional wiping cloths, which is very convenient and efficient.

[0026] In a feasible embodiment, the wiping component 35 is provided with fibers with a monofilament fineness of less than 1 dtex on the side facing the rear camera of the mobile phone. Since the fibers with a monofilament fineness of less than 1 dtex are ultrafine fibers, they have the characteristics of a high-density fabric structure and high cleaning ability, thus improving the wiping effect and reducing damage to the rear camera of the mobile phone during wiping.

[0027] In a feasible embodiment, the first pulley group 313 includes at least two first pulleys, each of which is evenly arranged around the transmission shaft 33, and the outer surface of each of the first pulleys abuts against the side of the transmission shaft 33, so that when the transmission shaft 33 rotates with the meshing of the gear teeth and the tooth grooves 111, each of the first pulleys is driven to rotate.

[0028] Optionally, when the number of the first pulleys is two, the two first pulleys are symmetrically arranged with the transmission shaft 33 as the center point, so that the transmission shaft 33 is relatively fixed between the two first pulleys.

[0029] Preferably, in order to better fix the position of the transmission shaft 33 relatively by the first pulley, the number of the first pulleys is 3 or more; for example, when the number of the first pulleys is 3, the three first pulleys are distributed in a triangle and the transmission shaft 33 is relatively fixed at the center of the triangle; when the number of the first pulleys is 4, the four first pulleys are distributed in a quadrangle and the transmission shaft 33 is relatively fixed at the center of the quadrangle; when the number of the first pulleys is 5, the five first pulleys are distributed in a pentagon and the transmission shaft 33 is relatively fixed at the center of the pentagon; when the number of the first pulleys is 6, the six first pulleys are distributed in a hexagon and the transmission shaft 33 is relatively fixed at the center of the hexagon; the transmission shaft 33 can be prevented from being displaced relative to the slider 31 during the movement or rotation process. Thus, the first pulleys uniformly arranged around the transmission shaft 33 can be used to prevent the transmission shaft 33 from falling off, and the transmission shaft 33 can be rotated smoothly.

[0030] In a feasible embodiment, a gear inner hole is provided at the center of the transmission gear 37, and the transmission gear 37 is sleeved on the transmission shaft 33 through the gear inner hole, so that the transmission gear 37 can be sleeved on the transmission shaft 33 through the gear inner hole.

[0031] In a feasible embodiment, the side of the sliding block 31 facing the housing 1 abuts against the outer surface of the housing 1 , and the sliding block 31 is supported by the outer surface of the housing 1 .

[0032] In a feasible embodiment, the slider 31 is provided with a guide pulley set on one side of the housing 1, and the slider 31 abuts against the outer surface of the housing 1 through the guide pulley set. When the slider 31 slides, the guide pulley set rolls on the outer surface of the housing 1, thereby reducing the friction between the slider 31 and the outer surface of the housing 1 when sliding, and the guide pulley set can make the slider 31 slide more smoothly along the guide groove 11.

[0033] Preferably, the outer surface of the shell 1 is provided with a groove parallel to the guide groove 11, and the guide pulley group reciprocates along the groove. The moving direction of the guide pulley group is limited by the groove, so that the slider 31 can reciprocate more stably.

[0034] In a feasible embodiment, the socket connection between the transmission shaft 33 and the transmission gear 37 is a prism structure with an even number of edges, and the hole shape of the gear inner hole is a polygon corresponding to the prism structure and connected by an even number of line segments in sequence. For example, when the socket connection between the transmission shaft 33 and the transmission gear 37 is a quadrangular prism structure, the hole shape of the gear inner hole is a quadrangular shape corresponding to the quadrangular prism structure; when the socket connection between the transmission shaft 33 and the transmission gear 37 is a hexagonal prism; the hole shape of the gear inner hole is a hexagonal shape corresponding to the hexagonal prism structure; when the socket connection between the transmission shaft 33 and the transmission gear 37 is an octagonal prism, the hole shape of the gear inner hole is an octagonal shape corresponding to the octagonal prism structure; when the transmission gear 37 moves with the transmission shaft 33, the transmission gear 37 rotates through the meshing of the gear teeth and the tooth grooves 111, and the corners of the polygonal gear inner hole will act on the side of the prismatic structure of the transmission shaft 33, so that the transmission shaft 33 rotates with the rotation of the transmission gear 37, which can increase the friction between the gear inner hole and the transmission shaft 33.

[0035] In a feasible embodiment, the socket connection between the transmission shaft 33 and the transmission gear 37 is a prism structure with an odd number of edges, and the hole shape of the gear inner hole is a polygon corresponding to the prism structure and connected by an odd number of line segments in sequence. For example, when the socket connection between the transmission shaft 33 and the transmission gear 37 is a triangular prism structure, the hole shape of the gear inner hole is a triangle corresponding to the triangular prism structure; when the socket connection between the transmission shaft 33 and the transmission gear 37 is a pentagonal prism; when the socket connection between the transmission shaft 33 and the transmission gear 37 is a heptagonal prism, the hole shape of the gear inner hole is a heptagonal prism corresponding to the heptagonal prism structure; when the transmission gear 37 moves with the transmission shaft 33, the transmission gear 37 rotates through the meshing of the gear teeth and the tooth grooves 111, and the corners of the polygonal gear inner hole will act on the side of the prismatic structure of the transmission shaft 33, so that the transmission shaft 33 rotates with the rotation of the transmission gear 37, which can increase the friction between the gear inner hole and the transmission shaft 33.

[0036] In a feasible embodiment, the wiping assembly 3 also includes a second pulley group 38 and a plurality of fixed rods 39, the second pulley group 38 is fixed to the slider 31 via the fixed rods 39; the second pulley group 38 abuts against the side of the transmission rod between the wiping component 35 and the transmission gear 37; the axis of the second pulley group 38 is parallel to the axis of the transmission shaft 33.

[0037] Optionally, the fixing rod 39 is inclined in a direction close to the transmission shaft 33, and a connecting component is provided at one end of the fixing rod 39 close to the transmission shaft 33, and the fixing rod 39 is fixedly connected to the second pulley block 38 through the connecting component. If the slider 31 is fixed to the transmission shaft 33 only through the first pulley block 313, the transmission shaft 33 may be offset during the movement of the slider 31 driving the transmission shaft 33. In this embodiment, two different force points appear during the movement of the slider 31 driving the transmission shaft 33 through the second pulley block 38 and the connecting component, which can prevent the transmission shaft 33 from being offset or tilted during movement and rotation, and is conducive to improving the balance of the transmission shaft 33 during movement and rotation.

[0038] Preferably, the fixing rod 39 is parallel to the transmission shaft 33, which is beneficial to saving the space occupied by the fixing rod 39. Moreover, if the slider 31 is only fixed to the transmission shaft 33 by the first pulley set 313, the transmission shaft 33 may be offset during the movement of the transmission shaft 33 driven by the slider 31. In this embodiment, two different force points appear in the process of the movement of the transmission shaft 33 driven by the slider 31 through the second pulley set 38 and the connecting component, which can prevent the transmission shaft 33 from being offset or tilted during movement and rotation, and is beneficial to improving the balance of the transmission shaft 33 during movement and rotation.

[0039] In a feasible embodiment, the second pulley group 38 includes at least two second pulleys, the number of the fixing rods 39 is the same as the number of the second pulleys, each of the second pulleys is fixed to the slider 31 through the corresponding fixing rod 39, and each of the second pulleys is evenly arranged around the transmission shaft 33; the outer surface of each of the second pulleys abuts against the side of the transmission shaft 33, and then when the transmission shaft 33 rotates with the meshing of the gear teeth and the tooth grooves 111, each of the second pulleys is driven to rotate. Since the second pulley has the same function as the first pulley, the number and arrangement of the second pulleys can refer to the description of the first pulley, so it is not repeated here.

[0040] In this embodiment, at least two second pulleys evenly arranged around the transmission shaft 33 are used to prevent the transmission shaft 33 from falling and enable the transmission shaft 33 to rotate smoothly.

[0041] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
