[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0032] Embodiment one

[0033] Referring to Figures 1 to 4 The present application discloses a housing 10 assembly, which comprises a casing and a guard piece 15. Referring to Figure 2 The casing is provided with a mounting cavity 11, referring to Figure 1 The casing has a mounting surface 12, the mounting surface 12 is provided with a recessed portion 13, and the recessed portion 13 is recessed towards the mounting cavity 11. Referring to Figure 3 The guard piece 15 is detachably connected to the mounting surface 12. Among them, the recessed portion 13 is used for accommodating the connecting piece.

[0034] On the basis of the structure, when the shell 10 assembly of the utility model is used, the heating component, the sensor, the control system, the pipeline and other components are placed in the mounting cavity 11 of the casing, then the screws, bolts and other connecting pieces are placed close to the mounting surface 12 of the casing and extend into the recess 13, the connecting pieces are passed through the casing wall from the recess 13 and connected with the components in the mounting cavity 11, so that the components are firmly connected to the casing.

[0035] The connecting end of the connecting piece such as a screw or a bolt is connected with the component in the mounting cavity 11, and the head of the connecting piece (for example, the head of a screw) is located outside the casing and accommodated in the recess 13. After all the components and connecting pieces are installed, the guard 15 is detachably connected to the mounting surface 12. Specifically, the guard 15 can be installed on the mounting surface 12 by means of a detachable connection mode such as adhesion or a buckle structure. After installation, the whole machine can be hung on a wall, an off-road vehicle, an all-terrain vehicle or other scenes according to needs.

[0036] Since the head of the connecting piece is accommodated in the recess 13, there is no protruding part on the mounting surface 12, and the guard 15 can also keep the back of the whole machine flat after being connected to the mounting surface 12. In the scene of vehicle suspension, the shell 10 assembly of the present application abuts against the vehicle frame through the flat back, which can effectively avoid the direct contact between the exposed screw head and the vehicle paint. Even if vibration and jolt are generated during the driving of the vehicle, the screw head will not scratch and damage the vehicle paint.

[0037] In addition, the guard 15 protects the connecting pieces and components on the mounting surface 12 from damage by the external environment, and the detachability of the guard 15 facilitates subsequent maintenance and replacement work.

[0038] Further, the recess 13 is a groove, and the bottom wall of the groove is provided with a mounting hole 14, wherein the mounting hole 14 is used for passing the connecting piece into the mounting cavity 11.

[0039] On the basis of the structure, when installing, the component to be installed and the connecting piece are respectively located at the corresponding positions inside and outside the casing, the connecting piece is placed close to the mounting surface 12 and extends into the groove, then the connecting end of the connecting piece is passed into the mounting cavity 11 from the mounting hole 14 and connected with the component, and the head of the connecting piece is accommodated in the groove and abuts against the bottom wall of the groove.

[0040] The groove is integrally formed on the casing, and specifically, the groove can be formed on a metal casing by stamping process, or the groove can be formed on a plastic casing by injection molding process.

[0041] Thus, the groove provides a safe accommodation space for the connecting piece, so that the head of the connecting piece is not directly exposed, and the back of the whole water heater is more flat and smooth, thereby avoiding damage caused by accidental touching or impact. At the same time, the abutting of the head of the connecting piece and the bottom wall of the groove not only enhances the stability of the connection, but also reduces the risk of loosening of the connecting piece due to vibration or external force. In addition, the setting of the groove optimizes the space utilization of the whole shell 10 assembly, so that the connecting piece can be compactly installed on the cabinet and does not occupy additional space.

[0042] It should be noted that the recess 13 can also be a countersunk hole with a cylindrical or conical inner cavity for accommodating the head of the connecting piece such as a screw or a bolt. The recess 13 can also be a multi-stage stepped shape to accommodate connecting pieces of different sizes and types; and the multi-stage stepped structure can also provide additional support and stability to enhance the overall structural strength of the shell 10 assembly.

[0043] Further, referring to Figure 3 and Figure 4 , the guard 15 is a baffle, specifically, the baffle is provided with a countersink 151, referring to Figure 1 , the mounting surface 12 is provided with a first connecting hole 121, wherein the countersink 151 and the first connecting hole 121 are connected by a first fastener, and the end of the first fastener is located in the countersink 151.

[0044] On the basis of this structure, when assembling, the baffle is close to the mounting surface 12 of the cabinet, and the countersink 151 is aligned with the first connecting hole 121. Then a first fastener (such as a screw, a bolt, etc.) is used to pass through the countersink 151 and is screwed into the first connecting hole 121. After installation, the head of the fastener, that is, the end of the fastener, is located in the countersink 151.

[0045] Wherein, after the baffle is firmly connected with the mounting surface 12, the end of the first fastener is accommodated by the countersink 151, avoiding the end to be exposed, so that the surface of the baffle is also flat. At the same time, the end of the first fastener is completely embedded in the countersink 151, so that the connection between the baffle and the cabinet is more close, reducing the risk of loosening caused by vibration or external force.

[0046] Thus, the baffle covers the mounting surface 12, which can avoid the accumulation of external dust and debris in the recess 13 when the shell 10 assembly is used in outdoor environment, and protects the connecting piece and the back of the cabinet.

[0047] Further, referring to Figure 3 and Figure 5The shell 10 assembly comprises a hanging component 16. Specifically, the hanging component 16 comprises a first connecting plate segment 161, a second connecting plate segment 162, and a hanging plate segment 163. The first connecting plate segment 161 is detachably connected with the baffle. The two ends of the second connecting plate segment 162 are respectively connected with the first connecting plate segment 161 and the hanging plate segment 163. The first connecting plate segment 161 and the hanging plate segment 163 are oppositely arranged and form a hanging interval 165. The hanging interval 165 is used for being hung with an external support to hang the shell 10 assembly. The end of the hanging plate segment 163 is further provided with a guide plate segment 164. The guide plate segment 164 is used for guiding the external support to enter the hanging interval 165 and be hung against the hanging plate segment 163.

[0048] On the basis of the structure, when the shell 10 assembly is used, it can be moved to a position where it needs to be hung. The hanging component 16 is close to the external support. The guide plate segment 164 is used as a guide to guide the external support to enter the hanging interval 165 and be hung against the hanging plate segment 163.

[0049] Specifically, the external support can be a frame or a beam of an off-road vehicle or a sand vehicle. It can also be a hook or a support. By arranging the hanging component 16 on the back of the shell 10 assembly and hanging the external support with the hanging component 16, the shell 10 assembly can be supported in an outdoor environment and be suitable for various scenes.

[0050] It should be noted that the hanging component 16 of the present application is adapted to the width of the cross beam of the sand vehicle. The shell 10 assembly can be firmly hung on the cross beam of the sand vehicle by the hanging component 16. The back of the shell is in abutment with the frame. There is no exposed screw head on the shell, which will not scratch the paint of the vehicle.

[0051] The first connecting plate segment 161 is provided with a through hole. The baffle is correspondingly provided with a connecting hole. The through hole and the connecting hole can be connected by a fastener such as a screw or a bolt to firmly connect the first connecting plate segment 161 with the baffle. In addition, a clamping groove can be arranged on the baffle. The first connecting plate segment 161 can be clamped in the clamping groove by the self-gravity of the shell 10 assembly and is not easy to be separated. Thus, the baffle provides installation support for the hanging component 16 so that the shell can be hung by the hanging component 16.

[0052] Further, the shell 10 assembly comprises a handle 17 which is detachably connected to the top of the shell. The handle 17 has a limiting portion and a guiding portion. The limiting portion is used for limiting connection with the external support to hang the shell 10 assembly. The guiding portion is used for guiding the external support to slide towards the limiting portion.

[0053] On this basis, when using the shell 10 assembly, the handle 17 can be lifted as a whole to move the shell 10 assembly to a position where it needs to be hung, and then the external support is hung with the handle 17. Using the guide as a guide, the external support smoothly slides along the direction of the guide under the guidance of the guide. When the external support contacts the limiting part, the shell 10 assembly is stably hung.

[0054] Therefore, the shell 10 assembly can be moved as a whole by the handle 17, which is suitable for scenes that need to be frequently changed in outdoor environments. At the same time, the handle 17 can provide a hanging point, so that the shell 10 assembly can be stably hung on external supports such as branches, hooks, vehicle crossbeams, etc. Through the limiting connection of the limiting part and the external support, the stability and safety of the shell 10 assembly during hanging are ensured. The setting of the guide part makes the external support more easily and accurately slide to the limiting part and connect with it, which can reduce errors and inconvenience during installation and improve the hanging efficiency.

[0055] Further, referring to Figure 6 , the handle 17 includes an elbow pipe 171, which is bent towards the direction away from the shell, and the distance between the elbow pipe 171 and the shell gradually increases from the two ends of the elbow pipe 171 to the middle part of the elbow pipe 171. Among them, the middle part of the elbow pipe 171 forms a limiting part, and the two ends of the elbow pipe 171 form a guide part.

[0056] On this basis, when hanging, the shell 10 assembly is moved to a position where it needs to be hung, and the external support is first hung with the guide part (i.e. the two ends of the elbow pipe 171) of the elbow pipe 171. Under the action of the gravity of the shell 10 assembly, the external support will slide along the bending direction of the guide part towards the middle part of the elbow pipe 171, and when the external support contacts the limiting part, the shell 10 assembly will not slide towards the two ends.

[0057] Compared with the flat pipe and straight pipe design in the prior art, it is easy to tilt and sway left and right during use, and difficult to balance. The elbow pipe 171 handle 17 of the present application makes the shell 10 assembly slide along a specific path when hanging, and finally stay at the limiting part, improving the stability of the hanging and reducing the risk of falling due to shaking or external force. Among them, the guide part of the elbow pipe 171 plays a role in guiding the external support into the hanging position. Through the curved shape of the elbow pipe 171, the external support can more easily and accurately connect with the limiting part.

[0058] Further, the handle 17 comprises two connecting tubes 172, and the two connecting tubes 172 are oppositely arranged at two ends of the elbow tube 171. Wherein, the adjusting member 18 is arranged on the casing, and the adjusting member 18 is provided with a plurality of connecting positions, and the bottom end of the connecting tube 172 is detachably connected with any connecting position through the second fastener 173, so as to adjust the position of the casing.

[0059] On the basis of the structure, according to the actual use requirement, the bottom end of the connecting tube 172 is aligned with the selected connecting position, and the second fastener 173 (such as a screw, a nut, etc.) is used to fix it. When the position of the casing is adjusted by using the adjusting member 18, the second fastener 173 is loosened, the connecting tube 172 is moved from the current connecting position to another connecting position, and the second fastener 173 is used again to fix the connecting tube 172 on the new connecting position, so as to ensure the stability of the connection. When the position of the casing is adjusted, the handle 17 composed of the elbow tube 171 and the connecting tube 172 can be used to hang or carry the casing 10 assembly. The elbow tube 171 is hung on the external support (such as a hook, a support, etc.), so as to ensure that the casing 10 assembly is stably hung.

[0060] Therefore, by arranging a plurality of connecting positions, the connecting position can be replaced according to the hanging environment during use, the position of the casing is finely adjusted to meet different use requirements, and the connection is firm and reliable, so as to avoid loosening during hanging or moving.

[0061] Further, referring to Figure 7 , the adjusting member 18 comprises a first plate segment 181 and a second plate segment 182, and the first plate segment 181 and the second plate segment 182 are arranged perpendicularly. Wherein, the casing is provided with a connecting groove, the upper end of the first plate segment 181 is inserted through the connecting groove, and the second plate segment 182 abuts against the casing.

[0062] On the basis of the structure, referring to Figure 2 , the casing comprises a face shell 102, a bottom shell 101 connected to one side of the face shell 102, an upper sealing plate 104 and a lower sealing plate 103 arranged oppositely, and the face shell 102, the bottom shell 101, the upper sealing plate 104 and the lower sealing plate 103 jointly enclose a square casing. Wherein, the connecting grooves are arranged on both sides of the upper sealing plate 104.

[0063] When the adjusting member 18 is installed, first, the two adjusting members 18 are placed into the installation cavity 11, and then the first plate segments 181 of the two adjusting members 18 are respectively inserted through the connecting grooves on both sides of the upper sealing plate 104 and extended to the top of the upper sealing plate 104, at this time, the second plate segments 182 of the two adjusting members 18 abut against the lower surface of the upper sealing plate 104. Wherein, the second plate segment 182 is provided with a through hole, so that the fastener such as a screw or a bolt can pass through the through hole and be connected with the upper sealing plate 104.

[0064] Thus, the adjustment piece 18 is firmly connected with the shell, and the adjustment piece 18 provides mounting support for the handle 17. The second plate segment 182 is abutted with the lower surface of the upper sealing plate 104, which enhances the stability of the entire structure and prevents the handle 17 from shaking or falling off during use.

[0065] Further, referring to Figure 7 , a plurality of connection positions are arranged on the first plate segment 181. Specifically, the connection position is a limiting hole 183, and the opposite sides of the limiting hole 183 are provided with limiting grooves 184; correspondingly, the second fastener 173 is a screw, and the opposite sides of the screw are provided with limiting protrusions 174. Wherein, the limiting protrusions 174 are used to pass through the limiting grooves 184 when the screw is connected with the limiting hole 183, and are disengaged from the limiting grooves 184 after the screw is connected with the limiting hole 183 in place.

[0066] On the basis of this structure, the bottom end of the connecting pipe 172 is provided with an internal thread structure. When connecting the connection position with the connecting pipe 172, first align the screw with the selected limiting hole 183, and ensure that the limiting protrusions 174 are aligned with the limiting grooves 184. Then pass the screw through the limiting hole 183 and into the internal thread structure of the connecting pipe 172. At this time, rotate the screw, so that the screw is gradually screwed with the connecting pipe 172, and when the screw is rotated in place, the limiting protrusions 174 will be disengaged from the limiting grooves 184, thereby locking the screw on the adjustment piece 18, preventing it from loosening or falling off. Use the same steps to connect the bottom end of the connecting pipe 172 with the limiting hole 183 on another adjustment piece 18.

[0067] Thus, by connecting the connecting pipe 172 of the handle 17 with the connection position on the first plate segment 181, the adjustment piece 18 provides a stable support and connection point for the handle 17, so that the handle 17 can be firmly fixed on the shell. Through the cooperation of the screw and the limiting hole 183, and the locking mechanism of the limiting protrusions 174 and the limiting grooves 184, the stable connection between the connecting pipe 172 and the adjustment piece 18 is realized, which can reduce the risk of the handle 17 falling off due to screw loosening after multiple uses. This connection method is not only simple and convenient, but also has high reliability and stability.

[0068] In addition, it should be noted that the plurality of connection positions on the first plate segment 181 are arranged along the arrangement direction of the front cover 102 and the bottom cover 101 in the shell 10 assembly, so that when the handle 17 is connected with the connection positions at different positions, the front and rear positions of the entire machine can be adjusted when the handle 17 is hung with external support.
