Description

Technical Field

[0001] The utility model relates to a periscope motor lens driving mechanism and a periscope motor. Background Art

[0002] With the continuous progress of technology, imaging acquisition devices such as digital cameras, mobile phones with camera functions, video game consoles, PDAs, etc. have become increasingly popular in the market. Their convenient function of being able to view the captured images immediately has become a convenient tool for the public to record things in daily life or work.

[0003] In order to achieve the zoom function, the existing common lenses need to be able to extend and retract. In order to further reduce the volume of the lens and improve the portability of electronic devices, some manufacturers have invented a periscope lens (PrismType Lens). The lens of this periscope lens is hidden inside, and the incident light is refracted to the lens by a prism. The lens then adjusts the best shooting focal length by moving on a straight optical axis. Therefore, the periscope lens does not need to zoom by extending and retracting, thereby reducing the structural setting of the telescopic lens, which can greatly reduce the thickness and weight of the entire lens, so as to effectively improve the portability of the imaging acquisition device.

[0004] In the driving mechanism of the lens in the existing periscope lens, generally, balls are used as rolling components to achieve linear reciprocating motion. The ball structure is difficult to assemble, and the balls are easy to fall off during transportation and use, resulting in the failure of the mechanism. In addition, it is difficult to suppress the shaking of the ball structure during linear motion. Summary of the Invention

[0005] In view of this, the utility model provides a slide rail type lens driving mechanism and a periscope motor, which use a sliding component to replace the ball component, reducing the installation difficulty and improving the product stability.

[0006] To solve the above technical problems, the technical solution of the utility model is to adopt a slide rail type lens driving mechanism, which includes a lens carrier for installing the lens and a driving component for providing power for the lens carrier; it also includes a sliding component, and the sliding component includes a slide rail and a slide groove that cooperate with each other to slide; the lens carrier can make a linear reciprocating motion based on the sliding component under the drive of the driving component.

[0007] In some embodiments, the slide groove is opened on the lens carrier, and the slide rail can make a relative linear motion with the lens carrier; or, the slide rail is arranged on the lens carrier, and the lens carrier can make a relative linear motion with the slide groove.

[0008] In some embodiments, there are two parallel slide rails and slide grooves; the slide rails and the slide grooves are respectively matched in pairs; the contact between one slide rail and the slide groove is two opposite linear contacts, and the contact between the other slide rail and the slide groove is a linear contact at the top of the slide rail.

[0009] In some embodiments, the cross-sections of the slide rails are all arc-shaped; the cross-section of one slide groove is V-shaped, and the cross-section of one slide groove is V-shaped, so that two opposite linear contacts are formed between the slide rail and the inner wall of the slide groove; the cross-section of the other slide groove is trapezoidal, so that a linear contact is formed between the top of the slide rail and the inner wall of the slide groove.

[0010] In some embodiments, the [object] is at least divided into two sections, and there is a gap between each section.

[0011] In some embodiments, the sliding assembly further includes a base, and the slide groove or the slide rail is arranged on the base.

[0012] In some embodiments, magnetic components for mutual adsorption are correspondingly arranged on the base and the lens carrier.

[0013] In some embodiments, the driving assembly includes a driving coil and a driving magnet used in cooperation with the driving coil; one of the driving magnet and the driving coil is fixed on the lens carrier and can move linearly relative to the other.

[0014] In some embodiments, there are two sets of the driving assemblies, which are respectively arranged on opposite sides of the lens carrier.

[0015] The present utility model further provides a periscope motor, which includes the above-mentioned slide rail type lens driving mechanism.

[0016] The advantages of the present utility model are as follows:

In addition, the slide rail and the slide groove have a stable structure and are not prone to shaking during the sliding process.

[0018] In order to further reduce friction, the contact between a pair of slide rails and slide grooves is two left and right linear contacts, and the contact between the other pair of slide rails and slide grooves is a linear contact at the top of the slide rail. After such setting, the sliding is smoother and less driving force is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Unless otherwise specified, the exemplary specific embodiments / embodiments shown will be understood to provide exemplary features of various details of some ways that can implement the technical concept of the present disclosure in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various specific embodiments / embodiments can be additionally combined, separated, interchanged, and / or rearranged.

[0027] First embodiment

[0028] As Figure 1 shown, the first embodiment of the present utility model provides a sliding rail type lens driving mechanism, including a lens carrier 1 for installing a lens and a driving component 100 for providing power to the lens carrier 1; further including a sliding component 200, the sliding component 200 includes a sliding rail and a sliding groove that cooperate with each other; the lens carrier 1 can make a linear reciprocating motion based on the sliding component 200 under the drive of the driving component 100.

[0029] In the present utility model, a sliding rail and a sliding groove are used in cooperation for sliding to replace the existing ball structure. The sliding groove and the sliding rail have simple structures and are convenient to assemble. Moreover, there will be no problem of falling during transportation and use. In addition, the sliding rail and the sliding groove have stable structures and are not prone to shaking during the sliding process.

[0030] In a specific embodiment of the present utility model, the sliding groove is formed on the lens carrier 1, and the sliding rail can perform a relative linear motion with the lens carrier 1; that is, the sliding rail is relatively fixed with other components of the periscope motor such as the housing and the mounting seat, while the lens carrier 1 can slide on the sliding rail by relying on the sliding groove. As shown in this embodiment, the above setting method is adopted. Of course, it can be understood that the sliding rail can also be arranged on the lens carrier, and the lens carrier can perform a relative linear motion with the sliding groove.

[0031] In order to avoid the imbalance caused by one side during sliding, in this embodiment, the sliding rail and the sliding groove are two parallel ones; the sliding rail and the sliding groove are respectively matched with each other two by two, so that the sliding is smoother.

[0032] As Figure 2 shown, in addition, according to the sliding principle, the smaller the contact area between two mutually sliding components, the smaller the frictional force, and thus the smoother the sliding. Therefore, in this embodiment, as Figure 2 shown, the first sliding rail 5b abuts against the opposite two side walls of the inner wall of the first sliding groove 5a, and the abutting part is a linear abutment. That is to say, the contact area between the first sliding rail 5b and the inner wall of the first sliding groove 5a is only the area of two lines, and the abutting part is axisymmetric with respect to the sliding rail. The line contact is the minimum contact method for the sliding rail and the sliding groove to achieve sliding, and the left and right line contacts in the same sliding groove can limit the shaking of the sliding rail in the left and right directions.

[0033] In order to further reduce the contact area, in this embodiment, the contact part between the first sliding rail I5c and the first sliding groove I5d also includes a linear contact between the top of the first sliding rail I5c and the inner wall of the sliding groove. Both sliding rails are respectively in contact with the inner wall of the sliding groove from the left and right and the top, and are limited from three directions to further avoid shaking.

[0034] As Figure 3 、 Figure 4 shown, more specifically, in this embodiment, the cross-sections of the first sliding rail 5b and the second sliding rail 5c are both arc-shaped; among them, the cross-section of the first sliding groove 5a is V-shaped, so that the contact part between the first sliding rail 5b and the first sliding groove 5a is two opposite linear contacts. There are only two point contacts between the V shape and the arc shape, and extending to the entire first sliding rail 5b and the first sliding groove 5a is two line contacts.

[0035] The cross-section of the second sliding groove 5d is trapezoidal, such that the contact between the second sliding rail 5c and the second sliding groove 5d is a line-type contact formed by the top of the second sliding rail 5c and the inner wall of the second sliding groove 5d. There is only a single point of contact between the trapezoid and the arc, and when extended to the entire second sliding rail 5c and second sliding groove 5d, it becomes a line contact.

[0036] In order to further reduce the contact area and thus reduce friction, both the first sliding groove 5a and the first sliding groove I5d can be axially divided into two or more segments, with a gap between each segment. As Figure 3 shown, the case where the sliding groove is divided into two segments is demonstrated in this embodiment.

[0037] In this embodiment, for ease of setting, the sliding assembly 200 further includes a base 7, and the sliding groove or sliding rail is provided on the base 7. The base 7 is used to be fixed to other components of the motor, such as the mounting seat, so that the sliding groove or sliding rail is relatively stationary with respect to the mounting seat.

[0038] In order to make the lens carrier 1 fit more closely when sliding on the base 7, in this embodiment, magnetic components for mutual adsorption are correspondingly provided on the base 7 and the lens carrier 1. For example, adsorption magnets 6 and adsorption iron sheets 4 for mutual adsorption are respectively fixed. It should be noted that the positions of the adsorption magnet 6 and the adsorption iron sheet 4 can also be interchanged without limitation.

[0039] In this embodiment, the driving assembly 100 includes a driving coil 2 and a driving magnet 3 that cooperates with the driving coil 2 to generate a driving force; it should be noted that the driving coil 2 can repel the driving magnet 3 when powered on, but by changing the direction of the current, the driving coil 2 can also be made to adsorb to the driving magnet 3, thereby providing a driving force for the lens carrier 1. It can be foreseen that one of the driving magnet 3 and the driving coil 2 is fixed on the lens carrier 1 and can move linearly relative to the other. Their positions can also be interchanged without limitation. Specifically, taking the driving coil 2 fixed on the lens carrier 1 as an example, when the driving coil 2 and the driving magnet 3 repel each other, they move away from each other, causing the lens carrier 1 to move away from the driving magnet 3 accordingly; when the driving coil 2 and the driving magnet 3 adsorb to each other, they move closer, causing the lens carrier to move closer to the driving magnet 3 accordingly.

[0040] For balanced force, there are two sets of the driving assemblies, which are respectively arranged on opposite sides of the lens carrier 1. For ease of installation, mounting grooves for installing the driving assemblies are provided on both sides of the lens carrier, and the driving coil 2 or the driving magnet 3 can be fixed in the mounting grooves.
