Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that the embodiments are a part of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts
The every other embodiment obtained, belongs to the range of utility model protection.
As shown in Fig. 1~Figure 11, the utility model embodiment discloses a kind of electronic equipment, comprising: first shell 1, the
The first side of one shell 1 is equipped with counterbore；Second shell 2；Roll wheel assembly, roll wheel assembly include: bracket 3, idler wheel 4 and roller bearing 5,
Idler wheel 4 is socketed on roller bearing 5, and can roll around roller bearing 5, and roller bearing 5 is set to the stage portion 6 of counterbore, and idler wheel 4 at least partly stretches out counterbore
And contacted with second shell 2, bracket 3 is connect with the first side of first shell 1, and bracket 3 abuts roller bearing 5, so that roller bearing 5 is fixed
In stage portion 6.
Here, first shell 1 is mainboard upper cover, and second shell is mainboard lower cover；Or first shell is mainboard lower cover, the
Two shells are mainboard upper cover.Preferably, first shell 1 is mainboard lower cover.
In order to avoid roller bearing 5 moves on the direction of the first side perpendicular to first shell 1, the fixation of roller bearing 5 is made more may be used
It leans on, and roller bearing 5 is avoided to rotate together with idler wheel 4, guarantee the rolling of idler wheel 4, it is preferred that bracket 3 has lug boss and lug boss
The nip portion of connection, lug boss and 4 shape of idler wheel cooperate, and nip portion is connect with first shell 1, and nip portion is abutted with roller bearing 5.
It should also be noted that, due to bracket 3 lug boss and 4 shape of idler wheel cooperate, but the lug boss of bracket 3 not with rolling
Wheel contact avoids interfering idler wheel work.Nip portion is connect with first shell 1, and nip portion is abutted with roller bearing 5, referring to diagram, also
It is to say, bracket 3 covers counterbore, connect with first shell 1, in this way, can also prevent idler wheel 4 from falling off.
Lug boss is engraved structure, is provided with multiple through-holes.The aperture of multiple through-holes can be identical, can also not
Together.When the aperture difference of multiple through-holes, positioned at idler wheel on the region of lug boss orthographic projection, other regions of aperture ratio lug boss
It is big.Through-hole can avoid enter into the foreign body obstruction roller motion between lug boss and idler wheel, and foreign matter can be discharged from through-hole.Rolling
Take turns the big of other regions of aperture ratio lug boss on the region of lug boss orthographic projection, it is ensured that bracket support strength it is same
When, promote foreign matter to be discharged from the through-hole of large aperture.Optionally, using screw 7 that bracket 3 and first shell 1 is fixed.The purpose is to
In order to which installation and removal are convenient.
Specifically, roller bearing 5 is parallel with the width direction of the first side of first shell 1.
Preferably, the diameter of the sleeve joint hole of idler wheel 4 is greater than the diameter at 5 middle part of roller bearing.
Here, idler wheel 4 is the cylindrical roller of inner hollow.
Optionally, bracket 3 is fixedly connected with the first side of first shell 1 by screw 7.
As shown in Figure 10, in one example, the quantity of idler wheel 4 is two, and the quantity of roller bearing 5 is two, and two idler wheels 4 divide
It is not socketed on corresponding roller bearing 5, and can be rolled around roller bearing 5.
It should be noted that the layout designs of the component in order to not influence the electronic equipment being set in first shell 1,
And during preventing first shell 1 and second shell 2 from relative motion occurs by idler wheel 4, buckling deformation occurs, more preferably,
Counterbore is located at the predeterminated position at the edge of the first side close to first shell 1.
It should be noted that the quantity of counterbore is two, two counterbores are respectively provided at the first side close to first shell 1
First edge the first predeterminated position and close to first shell 1 first side second edge the second predeterminated position.
Here, first edge and second edge are two edges that the first cover board 1 is opposite, and first edge and second edge
It is parallel with the length direction of the first side of first shell 1 respectively.
Below with regard to the installation process of Figure 10 brief description idler wheel 4, roller bearing 5 and bracket 3.
Firstly, first idler wheel 4 is socketed on roller bearing 5, it should be noted that the diameter of the sleeve joint hole of idler wheel 4 is greater than roller bearing 5
The diameter at middle part, that is to say, that between idler wheel 4 and roller bearing 5 with being combined into clearance fit, and then by idler wheel 4 and roller bearing 5
Component is placed in counterbore, wherein roller bearing 5 is placed in the stage portion 6 of counterbore, and idler wheel 4 at least partly stretches out counterbore and and second shell
Body 2 contacts, and then, then the first side that bracket 3 is placed in first shell 1 is covered counterbore, finally, locking screw 7, makes bracket
3 connect with the first side of first shell 1, bracket 3 abut roller bearing 5, each part be installed in place after schematic diagram such as Figure 11 institute
Show.
It should be noted that the stage portion 6 of counterbore plays position-limiting action, the rotation of roller bearing 5 is limited.
Preferably, the intensity of bracket 3 is greater than the intensity of first shell 1.
Here, the intensity of bracket 3 is greater than the intensity of first shell 1, so as to further strengthen the strong of first shell 1
Degree.
Optionally, counterbore is squared counter bore.
Preferably, the wear resistance of idler wheel is greater than preset value.
Here, the material of idler wheel can be used polyformaldehyde thermoplastic crystalline polymer (Polyformaldehyde, POM), this
The idler wheel of embodiment is POM idler wheel.
In addition, electronic equipment further include: the photographic device (not shown) being set in first shell 1.
In addition, electronic equipment further include: the display screen 8 being fixedly connected with second shell 2.
It is connected it should be noted that being rolled between first shell 1 and second shell 2 by roll wheel assembly.Preferably, first
Shell 1 is mainboard lower cover, and second shell 2 is mainboard upper cover.When user applies the power along electronic equipment fuselage length direction to the
When two shells 2, idler wheel 4 forms the rolling upward relative to second shell 2 under the action of 2 frictional force of second shell, that is,
It says, first shell 1 is moved up relative to second shell 2 under force, then, the camera shooting in first shell 1 is set
Device can expose.Later, if user apply opposite direction power, first shell 1 under force relative to second shell 2 to
Lower movement, the photographic device being arranged in first shell 1 are blocked by second shell 2, so, it is possible to realize screen display effect comprehensively
Fruit.
Since the frictional force between idler wheel 4 and second shell 2 is rolling friction, frictional force is smaller, so sliding is compared
It is brisk smooth, solve in the past because sliding friction it is big caused by sliding have some setbacks be topic, improve the usage experience of user.
Electronic equipment provided by the embodiment of the utility model is connected by the rolling between first shell and second shell,
Original sliding friction is become into rolling friction, reduces the frictional resistance between electronic device shell, improves electronic equipment sliding
Smoothness promotes user experience.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
