Description

Technical Field

[0001] The utility model belongs to the technical field of generators, in particular to a generator casing. Background Art

[0002] The existing silent generator casing generally includes a left shell and a right shell, which are buckled together to form a closed shell. The left shell and the right shell are generally injection molded. Due to production errors or deformation of the shell in later assembly, the flatness of the buckling surface between the left shell and the right shell is poor, resulting in a gap in a local part between the left shell and the right shell. Due to the different positions of the uneven buckling, the width of the buckling gap between the left and right shells is uncontrollable at different positions.

[0003] At present, the China Patent Network discloses a generator housing and its generator [Authorization Announcement No.: CN208226761U], which includes a left shell and a right shell that are interlocked. The left shell is integrally formed with a left handle shell, and the right shell is integrally formed with a right handle shell. The left handle shell and the right handle shell are buckled together to form a handle. There is a buckling gap directly below the handle, and the length of the buckling gap is basically equal to the length of the handle.

[0004] The above-mentioned generator housing and its generator have the following defects: after the existing left shell and right shell are buckled together, they need to be fixedly connected by several fasteners to make the left shell and the right shell firmly buckled, and the fasteners are basically arranged along the outer contour of the shell. The fasteners cannot be set at the position of the buckling gap, resulting in a larger buckling gap directly below the handle, and the buckling gap is at the top of the generator housing. When the generator is used outdoors, rainwater can easily enter the generator through the buckling gap, causing damage to the electrical components inside the generator. Utility Model Content

[0005] The purpose of the present invention is to solve the above problems in the existing technology and propose a generator housing. The technical problem to be solved by the present invention is how to solve the problem of a large buckle gap just below the handle of the generator housing.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A generator casing, the casing includes a left shell and a right shell that are interlocked, the casing has a handle, and a snap-fitting gap is provided directly below the handle. It is characterized in that a snap-fitting structure is provided at a position corresponding to the snap-fitting gap between the left shell and the right shell, and there are at least two snap-fitting structures, and all the snap-fitting structures are arranged at intervals along the length direction of the snap-fitting gap.

[0008] When the left shell and the right shell are fastened to each other, the positions of the left shell and the right shell corresponding to the fastening gaps are fastened through the fastening structure, so that the positions of the left shell and the right shell corresponding to the fastening gaps are hugged or fitted to each other, significantly reducing the width of the fastening gaps. There are at least two fastening structures, and all the fastening structures are spaced apart along the length direction of the fastening gaps, thereby ensuring that the width of each position of the fastening gaps can be significantly reduced, thereby improving the waterproof performance of the fastening gaps, and rainwater is not easy to enter the interior of the generator casing through the fastening gaps.

[0009] In the generator housing described above, the left housing has a left snap-fit ​​surface at a location corresponding to the snap-fit ​​gap, and the right housing has a right snap-fit ​​surface at a location corresponding to the snap-fit ​​gap. The snap-fit ​​structure includes a snap-fit ​​groove 1 provided on the left snap-fit ​​surface and a snap provided on the right snap-fit ​​surface, the snap-fit ​​engaging with the snap-fit ​​groove 1. With this structure, when the left and right housings are snapped together, all snap-fit ​​grooves 1 correspond to all snap-fits, and each snap-fit ​​engages with its corresponding snap-fit ​​groove 1, thereby significantly reducing the gap between the left and right snap-fit ​​surfaces.

[0010] In the aforementioned generator housing, a second snap-fit ​​groove is defined on the left snap-fit ​​surface along the length of the snap-fit ​​gap, and a snap-fit ​​ridge is defined on the right snap-fit ​​surface along the length of the snap-fit ​​gap. The snap-fit ​​ridge is inserted into the second snap-fit ​​groove. With this structure, the snap-fit ​​ridge is inserted into the second snap-fit ​​groove, thereby creating a certain degree of sealing effect, improving the waterproof performance of the snap-fit ​​gap and further reducing the probability of rainwater entering the generator housing.

[0011] In the generator housing, the lower edge of the second clamping groove has a chamfer. This structure makes it easier for the clamping rib to be inserted into the second clamping groove, thus facilitating assembly between the left and right housings.

[0012] In the aforementioned generator housing, both the left and right housings have upwardly raised protrusions at locations corresponding to the snap-fitting gaps. These protrusions are elongated and extend along the length of the snap-fitting gap, with arc-shaped tops. This configuration provides a circular arc-shaped top for the protrusions, which acts as a guide for rainwater. When rainwater strikes the protrusions, it flows along the arc-shaped tops of the protrusions, away from the snap-fitting gap, further enhancing the snap-fitting gap's waterproofing performance.

[0013] Compared with the prior art, the generator casing of the present invention has the following advantages: when the left shell and the right shell are buckled together, the positions of the left shell and the right shell corresponding to the buckling gap are clamped by the clamping structure, so that the positions of the left shell and the right shell corresponding to the buckling gap are tightly embraced or fitted to each other, significantly reducing the width of the buckling gap. There are at least two clamping structures, and all clamping structures are spaced apart along the length direction of the buckling gap, thereby ensuring that the width of each position of the buckling gap can be significantly reduced, thereby improving the waterproof performance of the buckling gap, and rainwater is not easy to enter the interior of the generator casing through the buckling gap.

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figures 1 to 7As shown, the generator housing 1 includes a left shell 2 and a right shell 3 that interlock with each other. The housing 1 has a handle 4, and a fastening gap 5 is formed directly below the handle 4. A snap-fit ​​structure is provided at the position corresponding to the fastening gap 5 between the left shell 2 and the right shell 3. There are at least two snap-fit ​​structures, and all snap-fit ​​structures are spaced apart along the length of the fastening gap 5. When the left shell 2 and the right shell 3 are fastened to each other, the positions corresponding to the fastening gap 5 of the left shell 2 and the right shell 3 are snapped together by the snap-fit ​​structure, so that the positions corresponding to the fastening gap 5 of the left shell 2 and the right shell 3 are tightly embraced or affixed to each other, significantly reducing the width of the fastening gap 5. There are at least two snap-fit ​​structures, and all snap-fit ​​structures are spaced apart along the length of the fastening gap 5, thereby ensuring that the width of each position of the fastening gap 5 can be significantly reduced, thereby improving the waterproof performance of the fastening gap 5, and making it difficult for rainwater to enter the interior of the generator housing through the fastening gap 5.

[0024] Furthermore, the left housing 2 has a left snap-fit ​​surface 20 at a position corresponding to the snap-fit ​​gap 5, and the right housing 3 has a right snap-fit ​​surface 30 at a position corresponding to the snap-fit ​​gap 5. The snap-fit ​​structure includes a snap-fit ​​groove 16 provided on the left snap-fit ​​surface 20 and a snap 7 provided on the right snap-fit ​​surface 30. The snap 7 snaps into engagement with the snap-fit ​​groove 16. In this embodiment, the end of the snap 7 has a barbed hook that hooks onto a raised portion within the snap-fit ​​groove 16. Of course, the snap-fit ​​structure protected by this application is not limited to the structure of this embodiment. When the left housing 2 and the right housing 3 are snapped together, all the snap-fit ​​grooves 16 correspond to all the snaps 7 one-to-one, and each snap 7 snaps into engagement with a corresponding snap-fit ​​groove 16, thereby significantly reducing the gap between the left snap-fit ​​surface 20 and the right snap-fit ​​surface 30. A second snap-fit ​​groove 21 is provided on the left snap-fit ​​surface 20 along the length direction of the snap-fit ​​gap 5, and a second snap-fit ​​ridge 31 is provided on the right snap-fit ​​surface 30 along the length direction of the snap-fit ​​gap 5. The snap-fit ​​ridge 31 is inserted into the second snap-fit ​​groove 21. The snap-fit ​​ridge 31 is inserted into the second snap-fit ​​groove 21 to form a certain degree of sealing effect, thereby improving the waterproof performance of the snap-fit ​​gap 5 and further reducing the probability of rainwater entering the generator casing. The lower edge of the port of the second snap-fit ​​groove 21 has a chamfer 22. The setting of the chamfer 22 facilitates the smooth insertion of the snap-fit ​​ridge 31 into the second snap-fit ​​groove 21, thereby facilitating the assembly between the left shell 2 and the right shell 3.

[0025] like Figure 3 As shown, the left shell 2 and the right shell 3 have an upwardly raised protrusion 8 at the position corresponding to the buckle gap 5. The protrusion 8 is long and arranged along the length of the buckle gap 5. The top of the protrusion 8 is arc-shaped. The top of the protrusion 8 has an arc-shaped top, which has the effect of diverting rainwater. When rainwater hits the protrusion 8, the rainwater will flow along the arc surface of the top of the protrusion 8 away from the buckle gap 5, further improving the waterproof performance of the buckle gap 5.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
