Detailed Description

The following detailed description of the present application in conjunction with specific embodiments, it should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the present application and its applications.

It is noted that unless explicitly specified and limited otherwise, the terms "center", "longitudinal", "transverse", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc., as used in this specification are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present application and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application. The terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated; thus, a feature defining "a first", "a second" may include one or more such features, either explicitly or implicitly; the meaning of "plurality" is two or more; "and/or" includes any and all combinations of one or more of the associated listed items. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

In a typical removable lens, it is usually removably secured to the body using a claw or similar bayonet connection. The connection mode requires that the claw arranged on the lens is aligned with the notch of the body when the lens is installed, so that the claw can smoothly enter the clamping groove through the notch, and the fastening and locking of the lens are completed.

In order to provide a stable and reliable connection, the jaws of the lens are typically designed to have a size approximately equivalent to the notch of the body. Such designs, on the one hand, require precise alignment between the lens and the body (which may also be referred to as "point-to-point mounting" in some cases), which is detrimental to quick assembly and disassembly of the lens. On the other hand, the claw and the machine body are easy to collide with each other, so that scraps or particles are generated. These debris and particulates can easily enter the interior of the body and lens and adversely affect the use and operation of the components therein.

The applicant finds that in the process of researching the present application, a rotation limiting mechanism arranged in the circumferential direction around the axis can be arranged to replace the traditional claw, so that any angle installation between the lens and the body is realized, and a series of defects caused by traditional point-to-point installation are effectively overcome.

Fig. 1 is a schematic structural diagram of a connection structure according to an embodiment of the present application. The connection structures are arranged on two different members, respectively, capable of cooperating with each other such that the "first member" and the "second member" are detachably fitted together. The term "detachably assembled" means that the two members are fastened and locked to each other without relative movement, and the fastening and locking are releasable.

In this context, "first member" and "second member" are used only to denote two structural components that exert a force on a connecting structure, and are not intended to be limiting in any way with respect to their specific implementation of structure, size or shape. It can be applied to any type of two separate structural components to achieve a detachable connection between the two components. For convenience of description, in the drawings of the specification of the present application, a lens is exemplarily shown as a first member, and a body is exemplified as a second member. Those skilled in the art will appreciate that they are provided for illustration only and not for the purpose of specifically limiting the application.

As shown in fig. 1, the connection structure may include: a movement restriction mechanism 100 and a rotation restriction mechanism 200.

The movement limiting mechanism 100 is a limiting mechanism for holding the first member 10 on the second member 20, and the rotation limiting mechanism 200 is a limiting mechanism for preventing relative rotation between the first member 10 and the second member 20. In this context, the term "hold" is used to indicate that the first member and the second member can be kept close to each other and in close contact against an external force. The term "relative rotation" is used to indicate that there is an unsynchronized rotation between the first member and the second member.

Thus, the first member and the second member can be fastened and locked by the combined action of the movement restriction mechanism 100 and the rotation restriction mechanism 200, and kept relatively fixed.

In the present embodiment, for convenience of description, portions of the movement restriction mechanism 100 provided at the first member and the second member may be referred to as "first movement restriction member 110" and "second movement restriction member 120", respectively. Similarly, portions of the rotation limiting mechanism 200 disposed at the first and second members are referred to as "first rotation limiting feature 210" and "second rotation limiting feature 220", respectively.

Specifically, the movement limiting mechanism 100 is designed as a movable member that can be switched between a locked state and an unlocked state. The "locked state" refers to a state in which the first movement restriction member 110 and the second movement restriction member 120 are engaged with each other, and a force is provided to hold the first member on the second member. The "unlocked state" refers to a state in which the first movement restriction member 110 is disengaged from the second movement restriction member 120, and no force is provided to hold the first component on the second component.

The specific manner of switching between the two states may be set as required in the actual situation, and is determined by the specific structure of the movement restricting mechanism to be actually used, and is not particularly limited herein, and may be, for example, manual switching by a user, motor-driven switching, or the like.

As shown in fig. 2, the second rotation limiting feature 220 has a second tooth formation 221. Which is located at the mounting end face of the second member and is arranged around the circumferential direction R1 of the axis L. Correspondingly, as shown in fig. 3, the first rotation limiting feature 210 has a first tooth structure 211. Which is located at the mounting end face of the first member. The first tooth form structure and the second tooth form structure have matched tooth form structures which can be meshed with each other to prevent relative rotation between the first member and the second member.

In this context, "mounting end face" refers to the surfaces of the first member and the second member that engage each other when locked and secured. It should be noted, however, that the mounting end face is not limited to describing a particular plane in solid geometry, but is merely intended to represent the orientation of a surface.

Taking an actual assembly process of the lens and the body as an example, as shown in fig. 2, the mounting end surface of the lens barrel 11, which is the main structure of the lens 10, can approach the mounting base 21 of the body 20 in the direction of the axis L. After the mounting end surface of the lens 10 is engaged with the mounting base 21 of the body 20, as shown in fig. 4, the first movement restriction member 110 and the second movement restriction member 120 are engaged with each other, fixing the lens 10 to the body 20.

In addition, the first tooth structure 221 of the first rotation limiting section 210 is engaged with the second tooth structure 221 of the second rotation limiting section 220 in response to the movement of the first rotation limiting section, thereby limiting the relative rotation between the lens 10 and the body 20. Thus, the lens 10 can be securely locked and fixed to the body 20 without occurrence of relative shake or vibration.

Taking the actual disassembly process of the lens and the body as an example, as shown in fig. 5, after the first movement restriction member 110 is separated from the second movement restriction member 120 (i.e., the movement restriction mechanism 100 is switched to the unlocked state), the first tooth structure 211 is also separated from the second tooth structure 221. The lens 10 may be moved away from the body 20 in the direction of the axis L by an external force.

In the connection structure provided in the embodiment of the present application, the relative assembly angle between the first member and the second member only needs to be able to satisfy that the first tooth-shaped structure 211 of the first rotation limiting part 210 can be intermeshed with the second tooth-shaped structure 221 of the second rotation limiting part 220. Herein, "relative assembly angle" refers to an angle through which the first member rotates about the axis L with the second member as a reference frame. Of course, the relative assembly angle is a relative concept, and may be an angle through which the second member rotates with respect to the first member as a reference frame. Is not limited herein

Since the second rotation limiting feature 220 forms a second tooth formation 221 disposed circumferentially around. Therefore, compared with the traditional claw connection mode, the connection structure does not need to keep a specific relative assembly angle of the first component and the second component in the assembly process, and can provide more usable relative assembly angles, thereby effectively overcoming the defects caused by the point-to-point installation mode.

Fig. 6 is an exploded view of the movement limiting mechanism 100 according to the embodiment of the present application. The movement limiting mechanism may allow the first member and the second member to be mounted at any relative assembly angle. In other words, the movement limiting mechanism does not limit the relative assembly angle.

In the present embodiment, as shown in fig. 6, the first movement limiting member 110 may include: a plurality of jaws 111. The second movement limiting member 120 includes: the locking step 121.

The claw 111 is a movable member reciprocally movable between a locked position and an unlocked position. Specifically, when the pawl 111 is in the lock position, the movement restriction mechanism 100 is in the lock state, and when the pawl 111 is in the unlock position, the movement restriction mechanism 100 is in the unlock state.

With continued reference to fig. 2, the locking step 121 is an annular step in the circumferential direction R1 around the axis. The clamping jaws 111 can be matched according to the specific structural size of the clamping jaws 111, and the clamping jaws 111 in the locking position can only abut against each other.

Since the locking step 121 is a member in the circumferential direction R1 around the axis. Therefore, the claw on the first member can be abutted against the locking step 121 on the second member at any relative assembly angle, so that the first member is held on the second member, and the effect of mounting and fixing at any angle is achieved.

Specifically, with continued reference to fig. 6, the first movement limiting member 110 may further include: a housing chamber 101 and an elastic member 112.

The accommodating cavity 101 may extend along a preset direction and be opened on the first member. Which has a size adapted to the jaws and is capable of functioning as a guide for guiding the jaws 111 to reciprocate in a preset direction between a locking position and an unlocking position.

The elastic member 112 is a member capable of applying an elastic force to the claw 111. Which can be received in the receiving cavity, applies an elastic force to the jaws 111 to urge the jaws 111 to move to the aforementioned locking position. In other words, the pawl 111 has a tendency to automatically return to the lock position by the provision of the elastic member.

In some embodiments, the resilient member 112 may be a compression spring that is in a compressed state within the receiving chamber. Both ends of the lock member are respectively abutted against the bottom surface of the housing chamber 101 and the lock member 111, and the lock member 111 can be driven to move to the lock position.

In some embodiments, as shown in fig. 7, the aforementioned claws 111 may be provided in a pair-wise manner. In this application, two claws provided in pairs are referred to as a "pair of claws". The pair of claws are oppositely arranged and located at the same straight line of the first component in the radial direction R2. The two jaws are reciprocally movable in the aforesaid radial direction between a locking position and an unlocking position. A pair of jaws 111 is exemplarily shown in fig. 8.

The mode that the jack catch provided in this application set up in pairs can play the foolproof effect, and the user only needs to press a pair of jack catch simultaneously and just can switch to the unblock state, has avoided the user to make the improper accident such as being switched to the unblock state of removal restriction mechanism because of the maloperation from this, causes the camera lens to drop.

In some implementations, with continued reference to fig. 7, the first rotation limiting feature 210 may include a plurality of racks 212 having a predetermined length.

Wherein, one side of the rack 212 is a tooth surface, forming the first tooth structure 211. The racks 212 may be provided in the same number as the jaws 111. The rack 212 is fixedly connected with the jaw 111 and can move correspondingly along with the jaw 111.

Correspondingly, as shown in FIG. 8, the second rotation limiting feature 220 may include a second feature body 222. The second part body 222 is an annular part structure, the circumferential edge of which is provided with a continuous toothed surface to form the aforementioned second toothed structure 221.

Alternatively, the circumferential edge may be the outer circumferential edge of the annular component structure, or the inner circumferential edge of the annular component body. An example of an inner peripheral edge is shown in fig. 8. Preferably, as shown in fig. 8, the continuous tooth surface (i.e., the second tooth structure 221) may be provided on the circumferential edge of the entire component to the effect of allowing the first and second members to be detachably assembled at any mounting angle.

In this embodiment, the rack 212 and the second member body 222 are configured with mating dimensional structures such that the rack 212 is capable of engaging at least a portion of the toothed surface of the second member body 222 when the movement limiting mechanism is in the locked state.

Taking the actual assembly process of the lens and the body as an example, as shown in fig. 9A, after the lens and the body are engaged with each other, the claw 111 can be held in the lock position by the elastic member. The claw 111 in the lock position and the locking step 121 abut against each other, so that a force in the axial direction is applied, and the lens 10 is held on the body 20.

At the same time, the rack 212 also follows the jaws 111 gradually approaching the second part body 222. In the process of approaching the two, the rack 212 with fewer teeth can automatically locate and mutually engage with the annular second part body 222, so that the lens 10 and the body 20 cannot rotate relatively.

Taking the actual disassembly process of the lens and the body as an example, as shown in fig. 9B, the user can press the claw 111 to move to the unlocking position in the radial direction R22 against the action of the elastic force. At this time, the pawl 111 in the unlock position is disengaged from the locking step 121, and the rack 212 is also separated from the second member body 222. Therefore, the lens can be separated from the body under the action of external force.

At least one advantageous aspect of the connection structure provided by the embodiments of the present application is: by utilizing the characteristic that the racks 212 are automatically located and meshed with each other when approaching to the annular second part body 222, the assembly of the first component and the second component at any installation angle is realized, and the convenience of lens assembly operation is effectively improved.

In many applications, in addition to maintaining structural relative fixation between the first member and the second member, additional electrical connection between the two members is required to assist in data information transfer and other functions. For example, a lens detachably mounted to the body also typically requires an electrical connection to be established with the body to perform an electrified function such as auto-focus.

In other embodiments, the connection structure may further include an electrical connection mechanism 300 for making the aforementioned electrical connection. As shown in fig. 9A, the electrical connection mechanism 300 may include: a connector 310 and a connector holder 320.

Wherein the connector 310 and the connection seat 320 are two parts respectively provided on the first member 10 and the second member 20. The two cooperate to establish an electrical connection between the first member 10 and the second member when the first member is held on the second member 20.

Specifically, as shown in fig. 9B, the connector 310 may have a plurality of metal probes 311 arranged in a radial direction. The specific number of the metal probes 311 may be set by a skilled person according to the actual situation, and is not particularly limited herein. Correspondingly, the connection socket 320 may have a plurality of metal rings 321 arranged circumferentially around the axis. The centers of the circles 321 overlap and are of different diameters, so that an annular gap is formed between two adjacent metal annular parts.

In an actual assembly process, after the first member is assembled and fixed to the second member, as shown in fig. 9B, the distal ends of the metal probes 311 are inserted into the corresponding annular gaps to contact the mating metal rings 321, thereby establishing electrical connection between the first member and the second member.

At least one advantageous aspect of the electrical connection mechanism provided by embodiments of the present application is: the metal ring 321 disposed circumferentially around the axis can be held in contact with the metal probe at any angle without restricting the relative mounting angles of the first member and the second member. In other words, the metal probes can be in contact with the mating metal ring when the first member is assembled to the second member at any angle.

It will be appreciated by those skilled in the art that any suitable adjustment, replacement or modification may be made based on the inventive concepts of the electrical connection mechanism of the present application, as long as the electrical connection mechanism does not limit the relative mounting angles of the first and second members. For example, the number of metal rings described above may be greater than the number of metal probes, and the dimensions of the metal probes and metal rings may be tailored to the specific structural design between the first member and the second member.

The application further provides a lens detachably assembled to the body. In some embodiments, as shown in fig. 3, the lens 10 includes a barrel 11 as a main body portion and a connection of portions. Among them, the mounting end surface of the lens barrel 11 may be provided with a first movement restriction member 110, a first rotation restriction member 210, and a connector 310. Alternatively, the first movement restricting member provided at the mounting end surface may be replaced with the second movement restricting member, and the first rotation restricting member provided at the mounting end surface may also be replaced with the second rotation restricting member. Of course, the connector provided on the mounting end surface may be replaced with a connection seat.

Thus, a plurality of different lens embodiments may be formed. For example, a lens provided with a first movement restriction member, a second rotation restriction member, and a connector, a lens provided with a second movement restriction member, a first rotation restriction member, and a connector, and the like.

The present application further provides a fuselage 20. In some embodiments, the body 20 has a mounting base 21 for mounting a lens. As shown in fig. 10, the second movement limiting member 120, the second rotation limiting member 220, and the connection seat 320 may be provided on the mounting base 21 of the body.

Alternatively, the second movement restricting member provided on the mounting base may be replaced with the first movement restricting member, and the second rotation restricting member provided on the mounting base may also be replaced with the first rotation restricting member. Of course, the connection base provided on the mounting base may be replaced with a connector.

Thus, a number of different fuselage embodiments may be formed. For example, a body provided with a first movement restriction member, a second rotation restriction member, and a connection base, a body provided with a second movement restriction member, a first rotation restriction member, and a connection base, and the like.

It should be noted that, in one or more embodiments of the present application, the foregoing mutual pairing relationship of the connection structures has been described in detail, and those skilled in the art may selectively provide corresponding components on the lens and the body thereof according to actual needs, so as to enable the lens to be detachably mounted on the body.

The foregoing is a further detailed description of the present application in connection with specific/preferred embodiments, and it is not intended that the specific implementation of the present application be limited to such description. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model, and these are all within the scope of the utility model.
