[0023] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein are used to be implemented in an order other than those illustrated or described herein.

[0027] In the description of the present disclosure, it is necessary to understand that the orientation or positional relationship indicated by the directional words is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present disclosure and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0028] The electronic device housing is mainly used to install electronic components in the electronic device. For example, the electronic components may include touch elements, circuit boards, resistors, capacitors, inductors, potentiometers, heat sinks, connectors, ports, and storage elements for storing and retrieving information. The touch elements will be assembled in the electronic device housing in the form of touch modules. The existing installation of touch modules requires the help of external processing technology. For example, the existing assembly of touch modules to the electronic device housing requires laser and riveting processes, which increases the installation of touch modules. The bending angle of the lock ear used in the existing assembly process is not easy to control, and excessive bending of the angle can easily lead to abnormal touch triggering. The existing assembly also uses a separate stainless steel spring arm part, however, the stainless steel spring arm is difficult to form. Due to the material's easy rebound characteristics, the size rebound is more serious after being left standing for a period of time after forming. Secondly, the size stability of the spring arm is poor after being pressed, which can easily cause the corner collapse of the touch module. In summary, the assembly scheme using the existing technology has more parts, more complex assembly, and higher cost.

[0029] To alleviate the above problems, refer to Figure 1, the embodiment of the present disclosure provides an electronic device housing, the structure of which includes: a housing body 10, the housing body 10 has a first mounting position 11 for mounting a touch module, illustratively, the first mounting position 11 includes but is not limited to a through hole position opened in the thickness direction of the housing body 10; further, the first mounting position 11 has a first accommodating groove 111, the first accommodating groove 111 is at least partially formed on one side of the inner wall of the first mounting position 11, and is extended along at least one inner wall of the side inner wall. Specifically, the first accommodating groove 111 has a groove bottom surface, and the groove bottom surface has an elastic arm portion 1111 and a reinforcement support portion 1112, the elastic arm portion 1111 and the reinforcement support portion 1112 are different structures that are separately arranged, wherein the elastic arm portion 1111 is used to provide the touch module with a pressing rebound force to avoid corner collapse, and the reinforcement support portion 1112 is used to overlap with the circuit board of the touch module and form a touch trigger structure. During the actual assembly process, by applying the electronic device housing of the embodiment of the present disclosure, the touch module can be directly installed in the first installation position 11 without the need for additional laser or riveting processes or lock ear bending processes. The process of installing the touch module in the electronic device housing is simpler and can greatly reduce material costs. At the same time, it can also simplify the dimension chain and improve the assembly dimension accuracy of the touch module.

[0030] Considering that the elastic arm 1111 can exert a pressing and rebounding force on the touch module, the first accommodating groove 111 has a groove opening 1113. When a user clicks one side of the touch module, the groove opening 1113 presses the elastic arm 1111 downward to form a rebounding pressure.

[0031] Furthermore, considering that the electronic device housing can be obtained through one-piece injection molding, the elastic arm portion 1111 can be an integral structure with the electronic device housing. Specifically, the elastic arm portion 1111 is formed by bending the bottom surface of the first accommodating groove 111 toward the groove opening 1113. Exemplarily, the elastic arm portion 1111 can be constructed as a metal sheet structure or a plastic elastic arm; or the elastic arm portion 1111 can be constructed as a compression spring or a torsion spring. In this way, due to the pressing and rebounding characteristics of the elastic arm portion 1111 itself, one side of the touch module can be set against the edge of the hole where the first mounting position 11 is located, and the other side of the touch module is set against the elastic arm portion 1111. In this way, the touch module can be stably installed in the electronic device housing with a limited position.

[0032] Considering the touch-click operation of the touch module in a pressed state, the reinforced support portion 1112 is constructed as a protruding structure on the bottom surface of the first accommodating groove 111. Specifically, the reinforced support portion 1112 includes a trigger boss 11121 and support legs 11122 connected to both sides of the trigger boss 11121, wherein the trigger boss 11121 is higher than the support legs 11122. In this way, pressing the touch module downward can realize the triggering touch of the circuit board by the trigger boss 11121.

[0033] Furthermore, considering the function of the touch support structure involved in the touch module, the first mounting position 11 of the disclosed embodiment also has a cross beam portion 1114, and the cross beam portion 1114 is formed on one side of the bottom surface of the first accommodating groove 111. The cross beam portion 1114 is constructed as a protruding structure extending toward the groove opening 1113. The protruding structure is integrally formed with the electronic device housing and can replace the application of the touch support.

[0034] Considering the stable assembly of the first installation position 11 and the limiting hook of the touch module, the first installation position 11 also has a limiting boss 1115. Specifically, the limiting boss 1115 is used to form a limiting structure with the limiting hook of the touch module, and the limiting boss 1115 is formed on at least part of the cross beam 1114, and the limiting boss 1115 is higher than the cross beam 1114. In this way, the structure of the limiting boss 1115 can be formed in a one-time molding process of the electronic device housing, saving material costs and labor assembly costs.

[0035] In summary, the reinforcing support portion 1112, the cross beam portion 1114 and the limiting boss 1115 are all integrally formed with the shell body 10; and / or the elastic arm portion 1111 is integrally formed with the shell body 10. In this way, material costs and labor assembly costs can be saved, and since the number of assembly parts is reduced, the assembly dimensional accuracy can also be improved.

[0036] Considering the specific structure of the first mounting position 11, the first mounting position 11 is configured as a through hole in the shell body 10, and along the thickness direction of the shell body 10, at least part of the through hole forms a first accommodating groove 111, and the first accommodating groove 111 includes at least two groove openings 1113, namely, a first groove opening 1113 at the top and a second groove opening 1113 at the side, and the crossbeam portion 1114 is formed at the edge of the second groove opening 1113. In this way, the first mounting position 11 can be adapted to the assembly of the touch module.

[0037] In summary, the first receiving groove 111 of the first mounting position 11 of the electronic device housing is provided with a whole beam as a structural reinforcement to replace the touch bracket. Plastic spring arms are provided at both ends of the beam portion 1114 to provide elastic force for both ends of the touch module to avoid corner collapse. A structural support is provided in the middle position of the beam portion 1114, specifically a trigger boss 11121, which overlaps with the pot piece on the circuit board to form a trigger structure. Compared with the traditional solution of assembling the touch bracket, the support structure size of this solution is more stable; a limiting boss 1115 is provided at the edge of the middle position of the beam, which forms a limiting structure with the limiting hook in the touch module. A 0.1mm gap can be designed to effectively prevent the generation of empty travel.

[0038] Furthermore, the touch module of the disclosed embodiment can be made of T0.4mm SUS304 stainless steel (traditional T0.5mm). Two locking ears are provided on the rear side of the touch module. The locking ears are formed by pressing and are parallel to the large surface of the touch module. Compared with the traditional bending forming solution, the forming angle and height of the locking ears are more accurate, so the front touch sensitivity is slightly affected after the screws are locked, while the traditional bending process may cause the touch pressing force value to be too large or too small due to the angle tolerance problem. Two supports are provided on the front side of the touch module, which cooperate with the electronic device housing. The support here maintains the same plane with the large surface of the touch module, which can avoid the dimensional height error caused by the forming bending. Further improve the stability and accuracy of the size. A limit hook is provided in the middle position of the touch module, which cooperates with the limit boss 1115 of the above-mentioned electronic device housing to prevent the problem of empty touch travel. A flat elastic arm is provided at the corner of the touch module, which can meet the impedance requirements of electromagnetic compatibility after overlapping with the grounding point of the circuit board.

[0039] The electronic device housing of the disclosed embodiment is constructed by bonding the circuit board and the Mylar structure with adhesive and then fastening them to the first mounting position 11 with screws. The structure is simple, and compared with the traditional solution, the metal spring arm riveting process is eliminated, and the spring arm is arranged on the electronic device housing body; at the same time, the touch support is eliminated, and the touch support is assembled by integrally forming a cross beam portion 1114 in the electronic device housing. This not only saves material costs and labor assembly costs, but also optimizes the size chain and greatly improves the size stability due to the reduction in assembly parts, thereby avoiding the pain points of unstable and short-lasting size of the metal spring arm.

[0040] The disclosed embodiment also provides a touch device, including the electronic device housing described above, and also including a touch device, the touch device including a circuit board, a Mylar structure and a metal plate, the circuit board has a trigger point, the trigger point position corresponds to the reinforcement support portion 1112, specifically, the circuit board is assembled with the reinforcement support portion 1112 of the electronic device housing corresponding to the trigger point, the circuit board is sandwiched between the metal plate and the Mylar structure, the metal plate is limited between the auxiliary limit portion and the shell body 10, and the trigger point is assembled with the trigger boss 11121. The touch device of the disclosed embodiment can achieve all the effects of the aforementioned electronic device housing, which will not be described in detail here.

[0041] The disclosed embodiment also provides an electronic device, including the electronic device housing as described above, the electronic device housing being the upper shell of the system end, and the electronic device housing also having a keyboard mounting position, the keyboard mounting position being used for assembling keyboard buttons. The electronic device of the disclosed embodiment can achieve all the effects of the aforementioned electronic device housing, which will not be described in detail here.

[0042] In summary, the electronic device housing, touch device and electronic device disclosed in the present invention are adopted. The structure of the electronic device housing itself has a first accommodating groove 111 for installing the touch module. The first accommodating groove 111 has an elastic arm portion 1111 and a reinforcing support portion 1112. When the touch module is installed in the first accommodating groove 111, the elastic arm portion 1111 presses against one side of the touch module and provides a pressing rebound force to the touch module to avoid corner collapse. The reinforcing support portion 1112 is used to contact the circuit board of the touch module. The reinforcing support portion 1112 can form a touch trigger structure with the circuit board in a pressed state. It can be understood that in a pressed state, the reinforcing support portion 1112 triggers the trigger circuit in the circuit board, that is, clicks on the touch module. In this way, when the touch module is installed in the electronic device housing, there is no need to perform additional process steps such as laser and riveting processes that increase working hours and resources. The installation and application of the touch module can be achieved by applying the structure in the electronic device housing itself.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
