Embodiment

For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.

The collapsible projection screen structure of a kind of mobile phone shown in Fig. 1 to 10; Comprise the collapsible projection screen assembly that is hinged on the cellular phone flip housing 2; Said collapsible projection screen assembly comprises flexible projection 7 and the corresponding rotating shaft 5 that is arranged on cellular phone flip housing 2 dual-sides; With this rotating shaft 5 be pivot be connected with can about the screen supporting bracket 1 launched; The long limit of two minor faces of said flexible projection 7 and part is fixed on the edge of screen supporting bracket 1, and flexible projection 7 mid portions are positioned at cellular phone flip housing 2 zones.

The long limit segmentation of said flexible projection 7 is provided with, and is the basis with the interlude that covers on the cellular phone flip housing 2, takes in each other, and at this moment, the outward appearance of mobile phone and use are similar with common clamshell phone.

To shown in Figure 10, the two ends of said rotating shaft 5 are set with can be with the rotating shaft 5 synchronous catch 3 that rotate like Fig. 7, and the sensing of this catch 3 is opposite with screen supporting bracket 1.

As shown in Figure 2, be provided with the stop bit shell fragment 4 that restriction catch 3 rotates relative to the position of catch 3 in the said cellular phone flip housing 2, play locking effect, to keep the preposition state to screen supporting bracket 1.

Shown in figure 11; Said stop bit shell fragment 4 comprises base plate 44 and upwarps the main shell foot 41 that is arranged at base plate 44 both sides symmetrically; The both sides of said main shell foot 41 also symmetry be provided with spademan shape submissile sheet 42; 42 of this submissile sheets are resisted against respectively on the position of bone 6 in the cellular phone flip housing 2, to increase the elasticity of main shell foot 41.

Embowment outside said main shell foot 41 tops and the catch 3 contacted positions; Make catch 3 when collapsible projection screen assembly folds or launch to put in place; Can utilize the elasticity of main shell foot 41 to withstand catch 3 does not turn round; Thereby make rotating shaft 5 and also akinesia of screen supporting bracket 1, play good locking action.

Particularly, when the projection screen assembly was in folded state, catch 3 was withstood by one of them main shell foot 41 of stop bit shell fragment 4, and screen supporting bracket 1 is locked at this moment, can't freely reverse; When the projection screen assembly is in deployed condition; Screen supporting bracket 1 outside Rotate 180 degree; And by the edge support limit of cellular phone flip housing 2, and baffle plate 3 correspondingly rotates to another side and is withstood by another main shell foot 41 of stop bit shell fragment 4, this moment, the screen supporting bracket also was locked; Can't freely reverse, it is smooth to guarantee that screen launches.

When needs change the folding or deployed condition of collapsible projection screen assembly; Under enough external force effects; Catch 3 can relatively move along the slick and sly contact-making surface on main shell foot 41 tops and push main shell foot 41 strain takes place by force; Thereby abdicate revolution space for catch 3, make rotating shaft 5 and screen supporting bracket 1 that predetermined actions takes place then, like folding or expansion.

Offer spacing hole 43 on the said base plate 44, this spacing hole 43 is sheathed on the limited post 8 in the cellular phone flip housing 2, and the position of further limiting stop bit shell fragment 4 makes its nonvoluntary moving.

Above-described the utility model execution mode does not constitute the qualification to the utility model protection range.The modification of being done within any spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included in the claim protection range of the utility model.
