DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.

Embodiment 1

Please referring to FIGS. 1 to 7, an armrest box structure in embodiment 1 of the present disclosure includes an armrest 10 and an armrest box 20, the armrest 10 is arranged on the armrest box 20, and the armrest 10 can slide backward relative to the armrest box 20. Original position of the armrest 10 on the armrest box 20 is shown in FIGS. 1, 2 and 5, and the position after the armrest 10 slides backward relative to the armrest box 20 is shown in FIGS. 3, 4 and 7.

As shown in FIGS. 3 and 4, an armrest storage box 11 is disposed at a backend of an upper portion of the armrest 10, and an armrest cover 12 is set above the armrest storage box 11, which can be open and shut. When the armrest cover 12 is open, an article area D is confined on the armrest 10 by the armrest storage box 11 and the armrest cover 12 together, which can be used for containing large-sized articles therein such as handbag, plastic bags etc. Since the middle of the back seats is seldom seated, even it is seated, the legs of the passenger seated there is much below than that of the armrest 10, which will not affect the backward slide of the armrest 10. Therefore, if the article area D is arranged at the backend of the armrest 10 and the armrest 10 slides backward, it is more convenient for the driver to deposit large-sized articles at the article area D, and rest his/her arm at the front of the armrest 10. In this way, the arrangement of the armrest 10 and the article area D will neither affect driving nor affect the travel experience of the passenger in the back seats.

By arranging the armrest storage box 11 in the armrest 10, when depositing articles at the article area D, the bottom of the deposited article can at least partially insert into the armrest storage box 11, which can help fix the article and avoid shaking or shift; further, by arranging an armrest cover 12 on the armrest storage box 11, when under open state, the armrest cover 12 can provide a surface for the article to lean against and therefore makes the article to be deposited in the article area D more stably.

In this embodiment, as shown in FIG. 8a, the armrest cover 12 is hinged at one sidewall 13 of the armrest 10 to facilitate the armrest cover 12 to open towards one side of the armrest 10 and further make the armrest storage box 11 exposed, and the opened armrest cover 12 and the armrest storage box 11 together provide support for the article.

As shown in FIG. 8a, in one embodiment, when the armrest cover 12 is open, it is fixed at the open position and stays vertically, therefore providing a surface for the article to lean against. For example, a positioning combination of a cylinder and a recess can be mounted between the armrest cover 12 and the armrest 10, which can make the armrest cover 12 fixed at the open position relative to the armrest 10. Since the position of the armrest cover 12 is fixed when it is open, the opened armrest cover 12 can provide a support for the deposited articles and improve its stability on the armrest 10. When the article is removed away, and the positioning function of the cylinder and recess is released between the armrest cover 12 and the armrest 10, the armrest cover 12 can be closed.

As shown in FIG. 8b, in another embodiment, when the armrest cover 12 is open, it has a tendency to close and provides a press to one side of the article deposited therein. For example, an elastic component such as spring 14 can be mounted between the armrest cover 12 and the armrest 10, one end of the spring 14 connects with the armrest 10, and the other end of the spring 14 connects with the armrest cover 12. Elastic resilience of the spring 14 endows the armrest cover 12 a tendency to close when it is open, along this line, the armrest cover 12 which has the tendency to close provides a press to one side of the article deposited therein, and improves the stability of the article on the armrest 10. When the article is taken away, the armrest cover 12 will be automatically closed under the action of the spring 14.

As shown in FIG. 8c, in yet another embodiment, the armrest cover 12 includes a first armrest cover 121 and a second armrest cover 122, both armrest covers 121, 122 are separately hinged at two sidewalls 13 of the armrest 10, and therefore both armrest covers 121, 122 can be separately opened towards two opposite sides of the armrest 10 to expose the armrest storage box 11. When depositing article at the article area D, when opened, said both armrest covers 121, 122 provide larger areas of support to the bottom or two opposite sides of the article, and therefore its stability on the armrest 10 is improved. In one embodiment, the open angle of said both armrest covers 121, 122 is respectively greater than 90 degrees and less than 180 degrees. For example, when the open angle θ is 135 degrees, said both armrest covers 121, 122 are sloping when they are open, together with the armest storage box 11, said both sloping armrest covers 121, 122 form a storage space gradually decreasing from top to bottom, which can provide certain clamping force to the article deposited therein. Further, when both armrest covers 121, 122 are open, the tendency to close will provide a press to two opposite sides of the article deposited in the storage space. For example, an elastic component such as a spring 14 is arranged between each armrest cover 121/122 and armrest 10, one end of the spring 14 connects with the armrest 10, the other end of the spring 14 connects with corresponding armrest cover 121/122, the elastic resilience of the spring 14 endows said both armrest covers 121, 122 a tendency to close when they are open, and the two armrest covers 121, 122 which has the tendency to close will provide certain press to the sides of the article deposited therein, and further improves its stability in the armrest 10.

Besides, when there is no need to deposit articles in the article area D, close the armrest cover 12, as shown in FIGS. 1 and 2, wherein the closed armrest cover 12 and a front part of the upper portion of the armrest 10 are connected into one body to provide a place to rest arm, similar as current armrest does.

In this embodiment, a cover switch 15 is mounted in the armrest 10, as shown in FIG. 1, which is used to control the armrest cover 12 to open and close. The cover switch 15 can be arranged at the upper surface of the armrest 10 or at other places. The cover switch 15 can be designed as various forms, and the method to control the armrest cover 12 open can also be various, which will not be described in detail here.

In this embodiment, please referring to FIGS. 5-7, an armrest box cover 22 is mounted on the armrest box 20, and the armrest 10 is arranged on the armrest box cover 22, and a guide rail (not shown) is sandwiched between a bottom surface of the armrest 10 and an upper surface of the armrest box cover 22, which leads the armrest 10 and the armrest box 20 to connect with each other in a sliding mode. When the armrest 10 slides backward relative to the armrest box 20, it has an elastic tendency to slide forward and has a certain damping to enable the armrest 10 to automatically slide back when necessary. Further, an armrest box storage tank 21 is disposed in the armrest box 20, the armrest box cover 22 is arranged over the armrest box storage tank 21, and the back of the armrest box cover 22 is hinged with the armrest box 20 via a hinge 23 to make the armrest box cover 22 open from anterior to posterior, as shown in FIG. 6, which facilitates the driver to put/take small items such as a charger, tickets to/from the armrest box storage tank 21.

In another embodiment, as shown in FIGS. 5-7, a spacing hole 16 is arranged in the bottom surface of the armrest 10, a switch slot 24 is mounted in the armrest box cover 22, and a bar linkage 30 is set in the switch slot 24. One end of the bar linkage 30 connects with an elastic switch 31, and the other end of the bar linkage 30 connects with a limit block 32, the elastic switch 31 and the limit block 32 have an elastic tendency extending out of the upper surface of the armrest box cover 22. When the driver wants to deposit large-sized articles on the armrest 10, press the cover switch 15, open the armrest cover 12, and deposit the article into the armrest storage box 11. Under the support of the armrest cover 12, the article is stably deposited in the armrest storage box 11. And then, along with the armrest 10 sliding backward, the spacing hole 16 in the armrest 10 aligns with the limit block 32 on the armrest box 20, and the limit block 32 is clipped into the spacing hole 16, the armrest 10 is finally limited at predetermined position. At this circumstance, the elastic switch 31 bounces up and protrudes out of the upper surface of the armrest box cover 22 under the action of the bar linkage 30. When the armrest 10 needs to be returned, press the elastic switch 31 downwards, the bar linkage 30 leads the limit block 32 to move down and leave away from the spacing hole 16. Since the armrest 10 has an elastic tendency to slide forward and has damping, the armrest 10 will automatically slide forward to its original position, when the driver can take his articles from the armrest 10 and close the armrest cover 12, or the armrest cover 12 is automatically closed.

In one embodiment, as shown in FIGS. 1-4, an armrest box container 25 is further mounted on the armrest box 20, straightly ahead of the armrest 10, which is used to deposit items such as a cup, or a drink bottle etc. The armrest box container 25 can be open-type structure or louvered structure. Besides, a shift lever 26 is located in front of the armrest box container 25.

Embodiment 2

Please referring to FIGS. 9-10, the armrest box in embodiment 2 of the present disclosure is basically the same as that in the above-mentioned embodiment 1, wherein the difference lies in that: in embodiment 2, a receiving groove 18 is mounted in forepart of the bottom surface of the armrest 10, and an auxiliary armrest 40 is arranged in the receiving groove 18. Further, the bottom surface of the auxiliary armrest 40 is arranged over the armrest box cover 22 under the support of an elastic component 41 such as a spring, because of this, the auxiliary armrest 40 has a tendency to bounce up under the action of the elastic component 41. When large-sized article is to be deposited on the armrest 10, the driver will first press the cover switch 15, open the armrest cover 12, and put his article into the armrest storage box 11, in this way, the article is stably deposited in the armrest storage box 11 with the assist of the armrest cover 12. Next, slide the armrest 10 backward, when the armrest 10 reaches its predetermined position, the auxiliary armrest 40 breaks away from the receiving groove 18 and automatically bounces up to combine with the armrest 10 to form a new larger armrest device. Because of this, the auxiliary armrest 40 not only extends the length of the armrest 10, which makes the driver more comfortable, but it also acts as a position limitation function to the armrest 10 and limits the armrest 10 at a fixed position. Just because of this, the above-mentioned position limiting stop structure such as the spacing hole 16, the switch slot 24 and the bar linkage 30 etc. of embodiment 1 is omitted in embodiment 2. Instead, the auxiliary armrest 40 provides position limitation function to avoid the armrest 10 to slide forward when braking. When the armrest 10 needs to return to its original position, just press the auxiliary armrest 40 downwards, and the armrest 10 will automatically slide forward to its original position under the action of its elastic tendency.

Further, an arc-shaped slot 42 is arranged at a backend of the auxiliary armrest 40, when the armrest 10 slides backward and the auxiliary armrest 40 bounces up, a front end of the armrest 10 is received in the arc-shaped slot and leans against the auxiliary armrest 40. The arrangement above can make the combination between the auxiliary armrest 40 and the armrest 10 more tightly. Meanwhile, the armrest 10 can provide certain support to the auxiliary armrest 40. Due to the existence of the arc-shaped slot 42, when pressing the auxiliary armrest 40, the pressure applied onto the auxiliary armrest 40 needs to be greater. Because of this, when resting arm on the auxiliary armrest 40, it is not easy for the armrest 10 to automatically return to its original position by a slight pressure onto the auxiliary armrest 40 by chance.

Embodiment 3

Please referring to FIG. 11, the armrest box in embodiment 3 of the present disclosure is essentially the same as that in the above mentioned embodiments 1 and 2, wherein the difference lies in that: in embodiment 3, the armrest cover 12 is hinged with a back end plate 19 of the armrest 10, in this way, the armrest cover 12 can be opened towards the back end of the armrest 10 to expose the armrest storage box 11. The opened armrest cover 12 together with the armrest storage box 11 can hold and fix the article deposited therein. For example, when the armrest cover 12 is opened, it can be fixed at its opening position and provide a support for one side of the article deposited therein to lean against it, as shown in FIG. 8a. In another example, when the armrest cover 12 is opened, it has a tendency to close and provide a press to the article deposited therein, as shown in FIG. 8b. Such schemes will not be described in detail herein.

Embodiment 4

Please referring to FIGS. 12-13, the armrest box in embodiment 4 of the present disclosure is basically the same as that in the above-mentioned embodiments 1-3, wherein the main difference lies in that: in embodiment 4, the armrest 10 is electrically driven to slide relative to the armrest box 20, and the electrical driven module is preferably applying a stepless drive motor 51 such as a step-motor, which can drive the armrest 10 to stay at anywhere on the armrest box 20. Along this line, the position of the armrest 10 can be adjusted according to the size of the articles. In this embodiment, a drive key 52 is arranged on the armrest box 20, which is used to control the running of the drive motor 51. When toggling the drive key 52 backwards, the drive motor 51 will drive the armrest 10 to slide backwards until the armrest 10 reaches the desired position, and then stop toggling drive key 52. When toggling the drive key 52 forward, the drive motor 51 will drive the armrest 10 to slide forward towards its original position until the armrest 10 reaches its original position, and then stop toggling drive key 52.
