One of purpose of setting is to make effective optical region phase that the camera lens in prism unit 201 and the first camera module 1 is constituted
Mutually it is aligned.This is extremely important for image quality.But, when two parts or unit are simultaneously located on prism base 202
When, lead to prism base 202 to carry two parts with constant weight.So, the middle part of prism base 202 becomes
Relatively fragile position on whole pedestal.When according to dual camera zoom module of the present utility model in use be subject to than
When stronger impact or vibration, prism base 202 can be in middle part fracture.
In order to avoid the middle part fracture of prism base 202, according to this utility model during position is provided with therebetween
Between reinforcing plate 2024.From fig. 5, it can be seen that middle reinforcing plate 2024 is along perpendicular to prism base 202 length direction, whole at it
Prism base 202 is run through on individual width extend.Middle reinforcing plate 2024 has certain thickness, thus enhancing prism base
The intensity of 202 middle parts.It is effectively prevented from middle reinforcing plate 2024 to rupture or damage.Additionally, middle reinforcing plate 2024 improves
The integral rigidity of prism base 202 so that the installation foundation of the first camera module 1 and prism unit 201 is more firm, both
Between position relationship ensured.
Referring to Fig. 6 as can be seen that another surface of the connection wall 2023 of prism base 202 end is provided with convex
Play 2026.According in this embodiment of the present utility model, it is provided with four positioning convex 2026.This four positioning convex
2026 are distributed on four angles on connection wall 2023 surface.These positioning convex 2026 are used for and the second camera module 3 below
On shooting shell 301 on location hole 301c cooperate, determine the company between prism base 202 and the second camera module 3
Connect position it is ensured that the optical axial of camera lens in the optical axial of prism 2012 and the second camera module 3 is mutually coaxial.Same with this
When, it is further opened with the through hole for making light pass through in the centre of connection wall 2023.The light being reflected by prism 2012 will
By this through hole, enter in the second camera module 3, the camera lens passing through reaches sensitive chip.
Also it is clearly shown that the free end 2011c of prism shell 2011 in Fig. 6.According to this embodiment party of the present utility model
In formula, this two free end 2011c are used for being fixedly connected with the second camera module 3 below.This will be done detailed further below
Thin description.
Fig. 7 shows the part-structure according to the second camera module 3 of the present utility model.

Show, shooting shell 301 is in hollow, rectangular column, has around housing department 301 a forming hollow, rectangular post, and is fixedly connected
Front panel 301e in housing department 301a one end.As shown in fig. 7, the length of front panel 301e is less than the width of shooting shell 301,
Because shooting shell 301 in the width direction be respectively arranged at two ends with two connecting portion 301b.This two connecting portion 301b be
Two depressions on shooting shell 301 side.In conjunction with the prism shell 2011 shown in Fig. 6 as can be seen that in the assembled condition, rib
The free end 2011c patch of mirror shell 2011 is embedded at the connecting portion 301b of this two depressions of shooting shell 301 end both sides, so
Pass through laser welding afterwards or both are fixed together by bonding.
As shown in fig. 7, four location hole 301c are provided with four angles of front panel 301e.By the second camera module
3 when being mutually combined fixing with the prism base 202 being provided with prism unit 201 and the first camera module 1, these location holes 301c
Play the role of positioning.
Also schematically show in Fig. 7 according to the motor module 302 in this embodiment of the present utility model, stabilization
Unit 303 and supporting shell 304.These parts are mutually coaxially disposed, and motor module 302 is arranged in stabilization unit 303, and can be
Move to offset the deviation that shake causes in stabilization unit 303 under the driving of drive mechanism.Stabilization unit 303 is integrally installed
In supporting shell 304, and can move in supporting shell 304, to drive the camera lens in camera module to be focused.
The ingredient according to the second camera module 3 of the present utility model is only schematically illustrated, not specifically in Fig. 7
Represent such as drive magnet, corresponding Hall element etc. in detail.
Fig. 8 schematically illustrates according to a kind of embodiment Zhong Guang steering mechanism 2 of the present utility model and the second shooting
Module 3 be connected with each other state.
After prism unit 201 is integrally mounted on prism base 202, just obtain prism list as shown in Figure 6
Unit 201 is combined with prism base 202.Then in prism base 202, bonded adhesives is coated on the end face of the second camera module 3
Water, and also attached painting bonding glue on the front panel 301e of the corresponding end-faces-shooting shell 301 of the second camera module 3.
Then, by the shooting shell 301 of four positioning convex 2026 on prism base 202 and the second camera module 3
Four location hole 301c be mutually aligned, be inserted in location hole 301c.So, the second camera module 3 and rib can just be ensured
The mutual close alignment of mirror unit 201.
After stating alignment in realization, the free end 2011c patch of prism shell 2011 is embedded in shooting shell 301 end both sides
This two depression connecting portion 301b at.Free end 2011c and connecting portion 301b are imposed with laser welding or it is also by applying
Cover glue and implement bonding, both are fixedly connected.Obtain combination as shown in Figure 8 after connection, but in Fig. 8, eliminate the first shooting
Module 1 and the circuit board 4 being located at the rightmost side accordingly.Circuit board 4 can be connected to the second shooting mould by modes such as bondings
After group 3.
The foregoing is only the embodiment of one side of the present utility model, be not limited to this practicality new
Type, for a person skilled in the art, this utility model can have various modifications and variations.All in essence of the present utility model
God and principle within, any modification, equivalent substitution and improvement made etc., should be included in protection domain of the present utility model it
Interior.
