Fig. 1 is a schematic perspective view of a lens module 100 according to an embodiment of the disclosure; fig. 2 illustrates an exploded structure diagram of the lens module 100 illustrated in fig. 1; fig. 3 shows a schematic cross-sectional structure of the lens module 100 illustrated in fig. 1; for ease of illustration, only matters relevant to the embodiments of the present application are shown.

Referring to fig. 1 to 3, a lens module 100 is provided in the embodiments of the present application, and includes a lens barrel 110, a target lens 120, an elastic member 130 and a cover 140.

The lens barrel 110 is a member for carrying the components in the lens module 100. The lens barrel 110 has a central axis L, and is a revolution body around the central axis L, and is substantially cylindrical. The central axis L and the first direction F1 are parallel to each other. The lens barrel 110 has a front end and a rear end disposed opposite in the first direction F1. The front end of the lens barrel 110 is located downstream of the rear end of the lens barrel 110 in the first direction F1. It will be appreciated that the front end of the lens barrel 110 and the rear end of the lens barrel 110 are relatively, and that the front end of the lens barrel 110 refers to the end of the lens barrel 110 that is closer to the outside, and that the lens barrel 110 may be connected to a corresponding device by means of the rear end of the lens barrel 110.

Specifically, taking fig. 1 to 3 as an example, the lens barrel 110 may include a cylinder portion 111 and a first mounting portion 112, both ends of the cylinder portion 111 in the first direction F1 being the front end and the rear end of the aforementioned lens barrel 110, respectively. That is, the front end of the lens barrel 110 is the front end of the tubular body 111, and the rear end of the lens barrel 110 is the rear end of the tubular body 111. The cylindrical body 111 is a solid of revolution about the central axis L, and the first attachment portion 112 is provided at the front end of the cylindrical body 111. The cylindrical body 111 and the first mounting portion 112 may be integrally formed or may be separately formed. The "one-piece structure" refers to a structure manufactured by means of, for example, an integral molding process, and the "split structure" refers to a structure in which two members are fixedly connected. The first attachment portion 112 may be provided around the central axis L in the circumferential direction of the front end of the tubular body 111, or may be provided in the front end of the tubular body 111 and provided with a through hole that can communicate with the internal space of the tubular body 111.

The target lens 120 is a lens detachably connected to the lens barrel 110 and provided at the front end of the lens barrel 110. That is, the objective lens 120 is detachably provided at the front end of the lens barrel 110. The target lens 120 includes a middle portion 121 and an edge portion 122 surrounding the middle portion 121. For example, the edge portion 122 of the objective lens 120 may be provided at the first mounting portion 112 at the front end of the lens barrel 110 in some of the cases illustrated above, facilitating the mounting. The portion of the intermediate portion 121 of the target lens 120 may or may not be in contact with the first mounting portion 112, and is not particularly limited herein.

The elastic member 130 is a member having elastic force. The elastic member 130 is disposed between the objective lens 120 and the barrel 110. That is, the elastic member 130 can provide elastic force acting on the target lens 120 in response to an external force. By way of example, the elastic member 130 may be a spring as illustrated in fig. 2 and 3. Of course, the elastic member 130 may be other elastic members, which are not particularly limited herein. Specifically, the elastic member 130 may be provided on a side of the first mounting portion 112 facing the target lens 120 in some of the cases illustrated above.

The cover 140 is a member that can be covered on the front end of the lens barrel 110, and the cover 140 has a first stopper w1. The cover 140 is detachably coupled to the front end of the lens barrel 110. The cover 140 has a limit position connected with the lens barrel 110 and a separation position capable of being separated from the lens barrel 110.

Specifically, taking fig. 1 to 3 as an example, the cover 140 includes a main body portion 141 and a second mounting portion 142 disposed circumferentially around an edge of the main body portion 141. That is, the second mounting portion 142 is substantially annularly provided. The first stopper w1 may be provided on the main body 141 or the second mounting portion 142. The first stopper w1 is shown to be provided on the main body 141.

The cover 140 is located at a limiting position, and the target lens 120 can abut against the first limiting portion w1 under the elastic force of the elastic member 130, so that the target lens 120 and the lens barrel 110 are relatively fixed. It can be understood that, in the case where the cover 140 is located at the limit position, the cover 140 is connected to the lens barrel 110, the cover 140 and the lens barrel 110 are relatively fixed, and a limit space of the target lens 120 is defined between the first limit portion w1 of the cover 140 and the front end of the lens barrel 110. The spacing space is used for accommodating at least part of the target lens 120 and spacing the target lens 120. In the limiting space, the elastic member 130 can provide an elastic force acting on the target lens 120, so that the target lens 120 is abutted against the first limiting portion w1 under the action of the elastic force, and the target lens 120 and the lens barrel 110 are relatively fixed. For example, the intermediate portion 121 of the target lens 120 may be in contact with the first stopper w1, or the edge portion 122 of the target lens 120 may be in contact with the first stopper w1. Taking fig. 3 as an example, a situation in which the edge portion 122 of the target lens 120 abuts against the first limiting portion w1 is illustrated.

The cover 140 is located at the separated position, and the objective lens 120 can be separated from the lens barrel 110. It is understood that the cover 140 can be separated from the lens barrel 110 with the cover 140 in the separated position. That is, the cover 140 may be separated from the lens barrel 110 at this time, or may be separated from the lens barrel 110 in response to the related force. When the cover 140 is separated from the lens barrel 110, the first limiting portion w1 of the cover 140 does not limit the target lens 120, and the target lens 120 can be separated from the lens barrel 110, and the target lens 120 can be detached. In the case that the cover 140 is separated from the lens barrel 110 in response to the related force, the target lens 120 can be separated from the lens barrel 110 by driving the cover 140 to separate from the lens barrel 110 under the elastic force of the elastic member 130, so as to separate the target lens 120 from the lens barrel 110. That is, in the case where the cover 140 is located at the separated position, the separation between the objective lens 120 and the lens barrel 110 may be achieved by the elastic force of the elastic member 130 or may be achieved by being disassembled in response to an external force. Can be correspondingly arranged according to actual use conditions, and is not particularly limited herein.

In this embodiment, the elastic member 130 is disposed between the lens barrel 110 and the target lens 120, and the target lens 120 is fixed by means of the cover 140 that is detachable from the lens barrel 110, so that the target lens 120 can be abutted against the first limiting portion w1 under the elastic force of the elastic member 130 when the cover 140 is located at the limiting position, so that the target lens 120 and the lens barrel 110 are relatively fixed, and the target lens 120 can be separated from the lens barrel 110 when the cover 140 is located at the separating position. Thus, the objective lens 120 is easily assembled and disassembled on the lens barrel 110. Since the objective lens 120 and the lens barrel 110 are detachable, the objective lens 120 can be replaced or maintained when the objective lens 120 is damaged. Therefore, the lens is convenient to maintain, and the use cost is reduced.

In addition, when the cover 140 is located at the limiting position, the target lens 120 abuts against the first limiting portion w1 of the cover 140 by means of the elastic member 130, so that the target lens 120 can be located at a relatively stable predetermined position, thereby being beneficial to keeping the optical axis and the optical incident surface of the target lens 120 in a more stable state, and improving the optical performance of the lens module 100.

Fig. 4 is a schematic bottom perspective view of the cover 140 of the lens module 100 shown in fig. 1; fig. 5 shows a schematic top perspective view of the objective lens 120 in the lens module 100 shown in fig. 1; for ease of illustration, only matters relevant to the embodiments of the present application are shown.

In some embodiments, please continue to refer to fig. 1 to 3, and refer to fig. 4 and 5, the first limiting portion w1 has a limiting surface m1, and the target lens 120 has an abutting surface m2. The cover 140 is located at a limiting position, and the limiting surface m1 and the abutting surface m2 abut against each other in the first direction F1. The limiting surface m1 and the abutting surface m2 may be partially abutted or entirely abutted.

In this way, by the abutment of the limit surface m1 and the abutment surface m2, the cover 140 and the target lens 120 are abutted in the first direction F1, and the target lens 120 can be limited and fixed in the first direction F1. Since the abutment between the limiting surface m1 and the abutment surface m2 is a surface abutment, the stability of the target lens 120 can be further improved.

In some embodiments, please continue to refer to fig. 4 and 5, the limiting surface m1 and the abutting surface m2 are both configured as planes. The plane where the limit surface m1 is located and the plane where the abutting surface m2 is located are intersected with the first direction F1. For example, taking fig. 4 and 5 as an example, the plane on which the limiting surface m1 and the plane on which the abutting surface m2 are located may be parallel to each other and perpendicular to the first direction F1. Of course, the plane in which the limiting surface m1 and the plane in which the abutment surface m2 are located may be disposed at other angles with respect to the first direction F1. The setting may be performed according to a specific use case, and this is not particularly limited in the embodiments of the present application.

Thus, in the case that the limiting surface m1 and the abutting surface m2 are both configured as planes, not only is processing and manufacturing facilitated, but also the abutting surface m2 is abutted on the limiting surface m1, and further improvement of stability of the target lens 120 in limiting and fixing is facilitated.

It is to be understood that, in other embodiments, the limiting surface m1 and the abutting surface m2 may be configured as surfaces with other shapes such as curved surfaces, so long as the objective lens 120 can be limited and fixed, which is not particularly limited herein.

In some embodiments, referring to fig. 4 and 5, the abutment surface m2 is configured as an annular surface; and/or, the limit surface m1 is configured as an annular surface. That is, at least one of the abutment surface m2 and the limit surface m1 is configured as an annular surface. Taking fig. 4 and 5 as an example, a case where the abutment surface m2 and the limit surface m1 are each configured as an annular surface is illustrated.

Specifically, the abutment surface m2 may be disposed at the edge portion 122 of the target lens 120 and around the middle portion 121 of the target lens 120. The abutment surface m2 is located at a side of the edge portion 122 facing away from the lens barrel 110, which is beneficial to the use of the middle portion 121 of the target lens 120.

In this way, by providing the contact surface m2 and/or the contact surface m2 as an annular surface, the contact limit can be performed on at least a part of the circumferential direction of the target lens 120, and a more stable contact limit structure x can be further formed.

In some embodiments, referring to fig. 1 to 3, the cover 140 is configured to rotate to a limit position and a separation position relative to the lens barrel 110. It is understood that the rotation of the cover 140 with respect to the lens barrel 110 may be a rotation about the central axis L.

In this way, the detachable connection between the cover 140 and the lens barrel 110 may be realized in a rotating manner, which is convenient for the user to use.

Fig. 6 is a schematic top perspective view of the lens barrel 110 of the lens module 100 shown in fig. 1; fig. 7 is a bottom perspective view of the lens barrel 110 of the lens module 100 illustrated in fig. 1; fig. 8 is a schematic bottom view of the cover 140 of the lens module 100 shown in fig. 1; for ease of illustration, only matters relevant to the embodiments of the present application are shown.

In some embodiments, please continue to refer to fig. 4, and refer to fig. 6 to 8 in combination, a limiting structure x disposed around the circumference of the lens barrel 110 is disposed at the front end of the lens barrel 110, and a fitting structure p for detachably fitting with the limiting structure x is disposed on the cover 140. The cover 140 is located at a limiting position, and the limiting structure x and the mating structure p are abutted against each other in the first direction F1. The cover 140 is located at the separation position, and the limit structure x and the mating structure p are separated from each other.

Specifically, taking fig. 2 and 6 as an example, the first mounting portion 112 includes a base portion 112a and a first annular portion 112b. The base 112a is provided at the front end of the tubular body 111, and a hole communicating with the inside of the tubular body 111 is provided in the base 112 a. The first annular portion 112b is provided on a side of the base portion 112a facing away from the cylindrical body 111. The limit structure x may be disposed outside the first annular portion 112b. The outer side of the first annular portion 112b refers to the side of the first annular portion 112b facing away from the central axis L. The fitting structure p may be provided inside the second mounting portion 142. The inner side of the second mounting portion 142 refers to the side of the second mounting portion 142 toward the central axis L.

That is, in the process of rotating the cover 140 with respect to the lens barrel 110, the position-limiting structure x and the engaging structure p have a position aligned in the first direction F1 and a position not aligned. In this process, under the condition that the limit structure x and the mating structure p are aligned in the first direction F1, the limit structure x and the mating structure p are abutted against each other in the first direction F1, and the cover 140 is located at the limit position; in the case where the limit structure x and the fitting structure p are not aligned in the first direction F1, the limit structure x and the fitting structure p are separated from each other, the cover 140 is not limited in the first direction F1, and the cover 140 is in a state capable of being separated from the lens barrel 110.

In this way, by setting the limiting structure x and the matching structure p, whether the two are aligned in the first direction F1 or not can be utilized to limit and separate in the process of rotating the cover 140 relative to the lens barrel 110, so as to realize detachable connection between the cover 140 and the lens barrel 110.

It can be appreciated that, in the case where the limiting structure x and the mating structure p abut against each other in the first direction F1, the pressing of the cover 140 on the target lens 120 can be more stable. In particular, the positioning surface m1 and the abutment surface m2 illustrated in the foregoing embodiments can be matched, which is more beneficial to improving the stability of the target lens 120 when being positioned and fixed.

In some embodiments, please continue to refer to fig. 3 and 4, and refer to fig. 6 to 8, the limiting structure x includes a plurality of first protrusions x1 circumferentially spaced around the lens barrel 110. The mating structure p includes a plurality of second protrusions p1 arranged at intervals around the circumference of the cover 140. The plurality of first protrusions x1 are disposed corresponding to the plurality of second protrusions p1. The cover 140 is located at a limiting position, the first protrusion x1 abuts against the corresponding second protrusion p1 along the first direction F1, and the first protrusion x1 is located upstream of the corresponding second protrusion p1.

Specifically, taking fig. 2, 4 and 6 as an example, the first protrusion x1 may be provided at an outer side of the first ring portion 112b, and the second protrusion p1 may be provided at an inner side of the second mounting portion 142. In the process of rotating the cover 140 relative to the lens barrel 110, the first protrusion x1 and the second protrusion p1 may be aligned or not aligned in the first direction F1, so as to achieve the detachable connection between the cover 140 and the lens barrel 110. The figure illustrates a case where the first protrusion x1 and the second protrusion p1 are provided with four, respectively. Of course, the number of the first protrusions x1 and the second protrusions p1 may be three or five or other numbers, which are not particularly limited herein. Referring to fig. 9 in combination, fig. 9 shows a schematic top view of the lens barrel 110 in the lens module 100 illustrated in fig. 1, and a plurality of first protrusions x1 may be equally spaced along the circumferential direction of the outer side of the first annular portion 112b. Referring to fig. 8 in combination, the plurality of second protrusions p1 may be equally spaced along the circumferential direction of the inner side of the second mounting part 142. Of course, the plurality of first protrusions x1 and the plurality of second protrusions p1 may be arranged at unequal intervals, and may be set according to specific use cases, which is not particularly limited in the embodiment of the present application.

It is understood that the number of the first protrusions x1 and the second protrusions p1 may be uniform or non-uniform. The first protrusion x1 may be mated with a different second protrusion p1, and the second protrusion p1 may also be mated with a different first protrusion x1.
