However, the assembly of the rear shell and the frame is complicated and troublesome: and a switching support is arranged between the rear shell and the frame, the switching support is fixed on the frame through a screw, and the rear shell is fixed on the switching support through the screw. Therefore, when the rear shell and the frame are assembled, multiple screw locking operations are needed, materials are multiple, and the assembly efficiency is low. In addition, when the rear case and the adapter bracket are locked, the operation from the bottom of the lower frame of the interactive flat plate is required, and the operability is poor.

Based on this, the present utility model provides a housing assembly and an interactive flat board, which provides a more convenient and faster assembly between the rear housing 20 and the bezel 10. Wherein the housing assembly is applied to an interactive tablet or other display device. The interactive flat board is also called as an interactive intelligent flat board or intelligent flat board, and the interactive flat board is applied in scenes such as conferences, multimedia teaching and the like.

This housing assembly and interactive dull and stereotyped, the mode through the cartridge realizes the equipment of backshell 20 and frame 10, and backshell 20 need not to use switching support and screw with the in-process of frame 10 equipment, has saved the step of installing switching support and lock a plurality of screws of attaching, and backshell 20's dismouting efficiency obtains promoting, and backshell 20 installs the operability strong.

Referring to fig. 1 to 11, an interactive tablet employing the housing assembly will be described.

The interactive tablet includes a display panel 90 and a housing assembly. The housing assembly includes a bezel 10, a rear case 20, a rear cover 40, a back plate 30, and side covers. The rear housing 20 is mounted in engagement with the rim 10.

Fig. 2 and 3 schematically show the structure of the frame 10. The frame 10 is provided with a slot 11 having a slot 114, the slot 11 extending along the length of the frame 10. The frame 10 includes a first clamping structure 12 and a first limiting structure 13, and the first clamping structure 12 is disposed on an inner wall of the slot 11.

The structure of the rear housing 20 is illustrated in fig. 1 and 2, and the rear housing 20 includes a first housing plate 21 and a second housing plate 24, which are connected, the first housing plate 21 is used for fast assembling with the frame 10, and the second housing plate 24 is used for assembling with other structures of the interactive flat board through a connecting piece, so as to realize integral fixation of the rear housing 20. The connection for mounting the second housing plate 24 may be, but is not limited to, a fastening screw. The second clamping structures 22 and the second limiting structures 23 are disposed on two sides of the first shell plate 21, and the second clamping structures 22 and the second limiting structures 23 are disposed along the first shell plate 21 at intervals. Referring to fig. 2 and 9, the second clamping structure 22 and the second limiting structure 23 are disposed on opposite sides of the first shell plate 21 in the y direction, and the second clamping structure 22 and the second limiting structure 23 are disposed at intervals along the z direction of the first shell plate 21. The second clamping structure 22 is close to the outer end of the first shell plate 21 in the z direction relative to the second limiting structure 23, so that the second clamping structure 22 advances into the slot 11 of the frame 10 when the first shell plate 21 is assembled with the frame 10.

The housing assembly is configured to: the first shell plate 21 can be inserted into the slot 11 of the frame 10 in an inclined state, and the clamping of the two clamping structures and the limit matching of the two limit structures are realized by rotating the first shell plate 21.

In fig. 1, 2, 6, and 9 to 11, the rear case 20 is assembled with the bezel 10. As can be seen from the figure, when the rear shell 20 and the frame 10 are in an assembled state, the end portion of the first shell plate 21 of the rear shell 20 is inserted into the slot 11 of the frame 10, the second clamping structure 22 is located in the slot 11, and when the second limiting structure 23 is in limiting fit with the first limiting structure 13, the second clamping structure 22 is clamped with the first clamping structure 12. Wherein, the second clamping structure 22 is clamped with the first clamping structure 12 to limit the first shell plate 21 to move to the outside of the slot 11; the second limiting structure 23 is in limiting fit with the first limiting structure 13 to limit the movement of the first shell 21 toward the inside of the slot 11 and limit the rotation of the first shell 21 relative to the frame 10 in at least one direction. As shown in fig. 2, the second limiting structure 23 limits the first shell plate 21 from rotating forward when in limiting engagement with the first limiting structure 13.

In fig. 1, 2, 6 and 9, the first clamping structure 12 cooperates with the second clamping structure 22 to limit the movement of the rear housing 20 along the z1 direction and along the y1 direction, and the first limiting structure 13 cooperates with the second limiting structure 23 to limit the movement of the rear housing 20 along the z2 direction and along the y2 direction. Wherein z1 is parallel and opposite to z2, y1 is parallel and opposite to y2, z1 is perpendicular to y1, and z2 is perpendicular to y2.

Taking the z1 direction and the z2 direction as the back and front directions, and the y1 direction and the y2 direction as the lower and upper directions as examples, when the first shell plate 21 is in the assembled state with the frame 10, the back shell 20 cannot be removed from the slot 11 of the frame 10 by simply translating forward, backward, upward and downward. By the cooperation of the two clamping structures and the cooperation of the two limiting structures, the rear shell 20 is kept in clamping connection with the frame 10 under the condition that the first shell plate 21 is not turned over.

It should be noted that, the directions z1, z2, y1, and y2 are only used to describe the relative positions and the matching relationship between the components, and are not limiting in this scheme. In other embodiments, the z1 direction is not limited to a backward direction, the z2 direction is not limited to a forward direction, the y1 direction is not limited to a downward direction, and the y2 direction is not limited to an upward direction.

For ease of understanding, fig. 4 to 9 illustrate a "tilt-insert, flip-snap" assembly of the rear housing 20:

as shown in fig. 4 and 7, in the first stage of insertion of the rear case 20: the rear case 20 is first tilted, and the end of the first case plate 21 of the rear case 20 is obliquely inserted into the slot 11 of the bezel 10, and the second snap-fit structure 22 of the rear case 20 is then inserted into the slot 11. The rear shell 20 is inclined, so that the second limiting structure 23 is staggered with the first limiting structure 13 in the process of inserting the first shell plate 21 into the slot 11, interference between the rear shell 20 and the frame 10 is avoided, and the inserting process of the first shell plate 21 is smooth.

As shown in fig. 5 and 8, in the second stage of insertion of the rear case 20: the rear housing 20 is held inclined deep into the slot 11 so that the second clamping structure 22 is adjusted to a position opposite to the first clamping structure 12. Wherein, due to the inclination of the rear housing 20, the second clamping structure 22 and the first clamping structure 12 will not interfere in the continuous insertion process of the rear housing 20.

As shown in fig. 6 and 9, in the third stage of insertion of the rear case 20: the rear housing 20 is rotated to rotate the second clamping structure 22 in a direction approaching to the first clamping structure 12 until the first limiting structure 13 is matched with the second limiting structure 23, at this time, the second clamping structure 22 is also clamped with the first clamping structure 12, at this time, the rear housing 20 and the frame 10 are in the assembly state, and the assembly of the rear housing 20 and the frame 10 is completed.

In the first stage and the second stage of inserting the rear housing 20, the rear housing 20 is continuously inserted into the slot 11 of the frame 10 in an inclined state, and the inclined manner is as follows: the second snap-in structure 22 is located on the side of the first shell plate 21 facing the first slot side wall 111 and facing the first snap-in structure 12, the first shell plate 21 being inclined to the side close to the second slot side wall 112. In the third stage of inserting the rear housing 20, the rear housing 20 rotates relative to the frame 10, so that the second clamping structure 22 approaches the first clamping structure 12, and the second limiting structure 23 approaches the first limiting structure 13, thereby realizing the engagement between the rear housing 20 and the frame 10.

After the assembly of the rear shell 20 and the frame 10 is completed, the rear shell 20 is also connected with other structures in the interactive flat plate, so that the turnover of the rear shell 20 relative to the frame 10 is limited, and under the condition that the rear shell 20 cannot be turned, the second clamping structure 22 is clamped with the first clamping structure 12, and the second limiting structure 23 is in limiting fit with the first limiting structure 13, so that the relative fixation between the rear shell 20 and the frame 10 is realized.

Compared with the prior art, when the rear shell 20 is assembled with the frame 10, a scheme of multiple locking and attaching by multiple adapting brackets and multiple screws is adopted; according to the shell assembly and the interactive flat plate, the slot 11 is formed in the frame 10, and when the rear shell 20 is installed, the rear shell 20 can be assembled with the frame 10 in a clamping way through simple actions of 'inserting' and 'overturning', so that a switching support and screws which are originally used between the rear shell 20 and the frame 10 are omitted; the back shell 20 and the frame 10 are assembled in a simple operation mode, the operability is high, and the assembly efficiency is improved. And, this kind of assembly method reduces the material kind, and overall structure is simpler, reduces material management cost.

The lower frame body in which the rear case 20 is fitted to the rim 10 is exemplified:

the lower frame body is provided with a slot 11, a first clamping structure 12 and a first limiting structure 13, and a notch 114 of the slot 11 is formed at the rear side of the lower frame body. When the rear shell 20 is installed, screw locking operation is not required to be performed from the bottom side of the lower frame, and the problem of poor locking operability caused by poor operation position or insufficient operation space is avoided. And, as shown in fig. 4 to 6, the rear case 20 can be directly inserted into the slot 11 of the lower frame body from back to front, and then the rear case 20 is turned over, so that the assembly of the rear case 20 and the lower frame body can be realized, and under the condition that the corner pieces are arranged at the two ends of the lower frame body in the length direction, the quick assembly between the rear case 20 and the lower frame body can be realized without removing the corner pieces.

Of course, in other embodiments, instead of the rear case 20 mounting method of "tilt-insertion and flip-engagement", the corner piece at one end of the frame may be removed, and the first case plate 21 of the rear case 20 may be inserted into the frame from the end of the frame through the end opening of the slot 11, so that the rear case 20 may be mounted.

In other embodiments, the housing assembly may also be configured such that the rear housing 20 is assembled with other housings, such as the rear housing 20 being assembled with an upper housing, or with a left housing, or with a right housing.

In an embodiment, to facilitate the assembly of the rear housing 20 to the frame 10 in a "tilt-insert, flip-snap" manner, the frame 10 includes a first avoidance groove 1101, and the first avoidance groove 1101 is a part of the area in the slot 11. When the rear shell 20 is assembled on the frame 10, the first avoiding groove 1101 and the second clamping structure 22 are located on two sides of the first shell plate 21, and the first avoiding groove 1101 is used for providing a shell plate accommodating space, and is particularly used for accommodating the front end of the inclined first shell plate 21. For the slot 11 without the first avoiding groove 1101, the slot 11 is provided with the first avoiding groove 1101, and the support rear shell 20 is obliquely inserted into the frame 10 through the notch 114 and then assembled with the frame 10 in a turnover mode, so that the operability is high and the assembly is simple.

As shown in fig. 5 and 8, in the second stage of the oblique insertion of the rear case 20, the first case plate 21 is inclined, the front end of the first case plate 21 enters the first avoiding groove 1101, the second clamping structure 22 faces the first clamping structure 12, and on this basis, the second clamping structure 22 and the first clamping structure 12 can be clamped by turning over the first case plate 21. Conversely, when the rear case 20 is detached, the first case 21 is turned over from the horizontal state to the inclined state, and the end of the first case 21 enters the first escape groove 1101, and at this time, the second locking structure 22 and the first locking structure 12 are prevented, so that the first case 21 can be pulled out of the slot 11. In other words, the first escape groove 1101 provides an escape space to conveniently accommodate the inclined first shell plate 21.

Correspondingly, the frame 10 further comprises a second avoidance groove 1102, when the rear shell 20 is assembled on the frame 10, the second avoidance groove 1102 and the second limiting structure 23 are located on two opposite sides of the first shell plate 21, and the second avoidance groove 1102 is used for avoiding the inclined first shell plate 21. As shown in fig. 5 and 8, in the second stage of the oblique insertion of the rear housing 20, the first housing plate 21 is inclined, and the position of the first housing plate 21 near the outer side of the slot 11 enters the second avoidance slot 1102, so that the interference between the second limiting structure 23 and the first limiting structure 13 is avoided, and the interference between the first housing plate 21 and the edge of the frame 10 is avoided. Of course, in other embodiments, the edge of the subframe 10 may be reduced instead of the second escape groove 1102.

In one embodiment, the slots 11 of the bezel 10 are configured as follows:

the slot wall of the slot 11 comprises a first slot side wall 111, a second slot side wall 112 and a slot bottom wall 113, wherein the slot bottom wall 113 is connected between the first slot side wall 111 and the second slot side wall 112. The slot bottom wall 113 and the notch 114 are located at both ends of the slot 11. The first clamping structure 12 is arranged on the first groove side wall 111. The first escape groove 1101 of the slot 11 is formed between the second groove side wall 112 and the groove bottom wall 113.

Thus, as shown in fig. 8, a certain distance is reserved between the first avoiding groove 1101 and the first clamping structure 12, the first avoiding groove 1101 is located at the oblique direction of the first clamping structure 12, so that the first shell plate 21 is conveniently inserted into the first avoiding groove 1101 in an oblique direction, and then the first shell plate 21 is turned over to enable the two clamping structures to be close to and clamped.

Taking the example that the slot 11 is arranged on the lower frame body of the interactive flat frame 10 and the notch 114 is arranged on the rear side of the lower frame body, the first avoiding groove 1101 is arranged on the front upper side of the first clamping structure 12, the first shell plate 21 can be inserted into the slot 11 in an upward inclined mode through the front end, and in the inclined insertion process, when the first shell plate 21 is inserted into the first avoiding groove 1101 on the front upper side, the first shell plate 21 is turned over to enable the second clamping structure 22 to move downwards, so that the second clamping structure and the first clamping structure are clamped.

With continued reference to fig. 3, 7 and 8, the second trench sidewall 112 is inclined with respect to the first trench sidewall 111. The second slot side wall 112 is inclined from a side closer to the slot 114 to a side farther from the slot 114 in a direction farther from the first slot side wall 111. In other words, the slot 11 gradually increases from approaching the slot 114 to the slot bottom wall 113. The second groove side wall 112 is obliquely arranged in such a way, so that the slot 11 is smaller in the position of the notch 114, the rear shell 20 is not easy to separate from the notch 114, the stability of the rear shell 20 is enhanced, the first avoiding groove 1101 can be further provided in the position of the corner of the bottom of the slot 11, and the first shell plate 21 for conveniently accommodating oblique insertion is provided.

In other embodiments, the first slot sidewall 111 and the second slot sidewall 112 may also be configured in parallel.

In an embodiment, the two clamping structures and the two limiting structures are configured in the following manner:

the first clamping structure 12 is a clamping groove, and the second clamping structure 22 is a clamping block. The clamping groove is arranged on the first groove side wall 111. The clamping groove comprises a first clamping surface 121 near one side of the first notch 114.

Referring to fig. 2, 6 and 9, when the second clamping structure 22 is clamped with the first clamping structure 12, the first clamping surface 121 limits the movement of the second clamping structure 22 along the z1 direction, and the first slot sidewall 111 limits the movement of the first shell plate 21 along the y1 direction, so as to limit the movement of the rear shell 20 along the z1 direction or the y1 direction.

The first limiting structure 13 is a limiting groove, the limiting groove is communicated with the notch 114, and the second limiting structure 23 is a limiting block. The limiting block is clamped into the limiting groove. The frame 10 includes a first limiting surface 131 and a second limiting surface 132 that are connected at an angle, and a limiting groove is formed between the first limiting surface 131 and the second limiting surface 132. The limiting block is abutted against the first limiting surface 131, and the limiting block is abutted against the second limiting surface 132.

With continued reference to fig. 2, 6 and 9, when the second limiting structure 23 is engaged with the first limiting structure 13, the first limiting surface 131 limits the movement of the second limiting block along the z2 direction, and the second limiting surface 132 limits the movement of the second limiting block along the y2 direction.

At least two manners of setting the frame 10 are provided below, so as to form a first limiting surface 131 and a second limiting surface 132 on the frame 10. Frame 10 arrangement one: the first limiting surface 131 is an end surface of the frame 10 where the notch 114 is located, the frame 10 further extends along the end surface where the notch 114 is located to form a limiting raised line 14, the second limiting surface 132 is a surface of the limiting raised line 14, and the limiting groove is formed between the first limiting surface 131 and the second limiting surface 132, in other words, the limiting groove is formed between the end surface of the frame 10 and the limiting raised line 14. The limiting protruding strips 14 may be provided in whole or in sections at intervals. The frame 10 is arranged in a second mode: a limit groove is directly formed in the position, adjacent to the notch 114, of the frame 10.

Taking the example that the rear case 20 is mounted on the lower frame of the frame 10 and the notch 114 of the slot 11 is provided on the rear side surface of the lower frame, z1 is a backward direction, z2 is a forward direction, y1 is a direction, and y2 is an upward direction. The first clamping structure 12 limits the rear housing 20 to move backward and downward, and the second limiting structure 23 limits the rear housing 20 to move forward and upward. In addition, when the second clamping structure 22 and the first clamping structure 12 are clamped in place, the second limiting structure 23 abuts against the first limiting surface 131 and the second limiting surface 132, and the first groove side wall 111 abuts against the side wall of the first shell plate 21, so as to limit the rear shell 20 to continuously overturn forwards, and provide overturn assembly in-place feedback.

In the embodiment illustrated in fig. 2, 6 and 9, the two clamping structures cooperate to not only prevent the rear housing 20 from translating out of the slot 11, but also prevent the rear housing 20 from shaking downward, and the two limiting structures cooperate to not only prevent the rear housing 20 from rotating and continuing to be inserted into the slot 11, but also prevent the rear housing 20 from shaking upward, so that the rear housing 20 and the frame 10 are in limiting cooperation in at least four directions through at least one another, thereby realizing more stable assembly.

In other embodiments, the first clamping structure 12 may be a clamping block, and the second clamping structure 22 may be a clamping groove, into which the clamping block is clamped. In other embodiments, the first limiting structure 13 may also be a limiting block, the second limiting structure 23 is a limiting groove, and the limiting block is clamped into the limiting groove.
