DETAILED DESCRIPTION
[0035] In order to make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.
[0036] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the description of a particular example will not necessarily be repeated in the description of each example. Of course, they are only examples and are not intended to limit the present application. Furthermore, reference numerals and / or letters can be repeated in different examples in the present application. Such repetition is for the purpose of simplicity and clarity and does not indicate a relationship between the various embodiments and / or arrangements being discussed.
[0037] For the purpose of description, spatial relative terms can be used in the description to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", and the like. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the description are interpreted accordingly.
[0038] In the design of the fan, the foot plate is an important component for supporting the entire fan structure, which not only needs to have sufficient strength and stability, but also needs to provide mounting space for electronic components (such as timers, swing switches, keyboard switches, electronic boards, etc.).
[0039] In the related art, electronic components are usually fixed on the upper foot plate by using an injection molding process, but in this way, the electronic components need to be demolded from multiple angles, which makes the demolding process extremely cumbersome, thereby affecting the production efficiency of the production process.
[0040] In order to solve the technical problem that the electronic element is fixed on the upper foot plate in the prior art, resulting in a relatively complex demolding process, the application provides a base assembly, which can improve the convenience of demolding of the electronic element.
[0041] Referring to Figures 1-7 The base assembly 10 provided by the application comprises an upper foot plate 100, a lower foot plate 200 and an electronic element 500.
[0042] The lower foot plate 200 is connected to the upper foot plate 100 and opposite to the upper foot plate 100, and a limiting structure 400 is arranged on the side of the lower foot plate 200 facing the upper foot plate 100, the limiting structure 400 and the lower foot plate 200 jointly form a limiting space 300, and the extending direction of the limiting structure 400 is consistent with the height direction of the lower foot plate 200.
[0043] The electronic element 500 is located in the limiting space 300 and connected to the limiting structure 400.
[0044] Since the upper foot plate 100 is directly exposed to the outside, the appearance requirement of the upper foot plate 100 is relatively high, and the electronic element 500 is fixed on the upper foot plate 100, which is easy to cause shrinkage, bubbles and other adverse appearance phenomena in the injection molding process.
[0045] In order to solve the shrinkage phenomenon of the electronic element 500 fixed on the upper foot plate 100, it is usually necessary to design a structure for preventing shrinkage, such as a headspace screw column structure, to prevent the shrinkage of the screw column. However, the headspace screw column structure requires the electronic element 500 to move in two directions when demolding, and the mold manufacturing cost of the headspace screw column structure is relatively high.
[0046] The lower foot plate 200 is usually located at the bottom of the fan 01, and the appearance requirement of the lower foot plate 200 is relatively low. Therefore, the limiting structure 400 is arranged on the side of the lower foot plate 200 facing the upper foot plate 100, the limiting structure 400 and the lower foot plate 200 jointly form a limiting space 300 for arranging the electronic element 500, and the extending direction of the limiting structure 400 is consistent with the height direction of the lower foot plate 200. Based on this, when the electronic element 500 is completed and needs to be demolded, it only needs to be demolded along the height direction of the lower foot plate 200, without the need for multi-direction demolding. Therefore, the demolding process is simplified, thereby improving the convenience of demolding of the electronic element 500.
[0047] In addition, since the mold with the headspace screw column structure is not needed, the mold opening cost can be saved.
[0048] In some embodiments, the limiting structure 400 comprises a plurality of limiting members 410, the plurality of limiting members 410 are arranged at intervals, and two adjacent limiting members 410 and the lower foot plate 200 jointly form the limiting space 300, and the electronic component 500 is clamped in the limiting space 300 and connected to the plurality of limiting members 410.
[0049] In some embodiments, each limiting member 410 comprises a connecting column 411 and a reinforcing rib 412, the reinforcing rib 412 is connected to the outer periphery of the connecting column 411, the connecting column 411 and the reinforcing rib 412 are both connected to the lower foot plate 200, the extension direction of the connecting column 411 and the extension direction of the reinforcing rib 412 are both consistent with the height direction of the lower foot plate 200, and the electronic component 500 is connected to the connecting column 411.
[0050] In some embodiments, the electronic component 500 can be fixed to the connecting column 411 by a screw, which is simple and quick to operate, does not require complex tools or processes, and reduces the assembly difficulty.
[0051] By introducing the design of the connecting column 411 and the reinforcing rib 412 in the limiting member 410 and combining the screw fixing mode, the stability, structural strength and vibration resistance of the electronic component 500 installation are improved, and the assembly process is simplified and the material cost is saved.
[0052] In some embodiments, the number of reinforcing ribs 412 is a plurality, and the plurality of reinforcing ribs 412 are arranged at intervals along the circumference of the connecting column 411.
[0053] In this way, by arranging a plurality of reinforcing ribs 412 arranged at intervals along the circumference of the connecting column 411, the stability of the connection between the limiting member 410 and the lower foot plate 200 can be improved.
[0054] In some embodiments, each reinforcing rib 412 comprises a reinforcing rib portion 4121 and a limiting portion 4122 connected to each other, the reinforcing rib 412 of each limiting member 410 is connected to the corresponding connecting column 411, the limiting portion 4122 of each limiting member 410 extends away from the lower foot plate 200, and the limiting portions 4122 of two adjacent limiting members 410 jointly cooperate to limit the radial movement of the electronic component 500 along the lower foot plate 200, thereby improving the stability of the electronic component 500.
[0055] In some embodiments, the upper foot plate 100 is detachably connected to the lower foot plate 200.
[0056] By detachably connecting the upper foot plate 100 to the lower foot plate 200, the convenience of disassembling the upper foot plate 100 and the lower foot plate 200 can be improved.
[0057] In some embodiments, the inner side wall of the upper foot plate 100 is provided with a plurality of first buckling parts 110, and the inner side wall of the lower foot plate 200 is provided with a plurality of second buckling parts 210, each of the second buckling parts 210 corresponding to one of the first buckling parts 110, and the second buckling parts 210 are buckled and fixed with the first buckling parts 110.
[0058] The detachable connection between the upper foot plate 100 and the lower foot plate 200 is achieved by buckling, which can improve the convenience of disassembling the upper foot plate 100 and the lower foot plate 200.
[0059] In some embodiments, the number of electronic components 500 and the number of limiting spaces 300 are both multiple, each of the limiting spaces 300 corresponding to one of the electronic components 500, and the multiple electronic components 500 include a swing switch 510, a timer 520, and a piano key switch 530.
[0060] For example, the user can click the swing switch 510, and then the MCU in the fan 01 controls the stepping motor to drive the fan 01 head to swing left and right, realizing the swing effect.
[0061] The user can rotate the timer 520 knob to select the required working time (such as 2 hours). The MCU starts the timing function, and automatically turns off the fan 01 when the time arrives.
[0062] For another example, the user can press the "power on" key in the piano key switch 530, and the signal is transmitted to the MCU, and the MCU starts the fan 01 motor, and the fan 01 starts running.
[0063] Alternatively, the user can press the "wind speed adjustment" key in the piano key switch 530, and the MCU adjusts the motor speed, and the fan 01 switches to the corresponding wind speed gear (low speed, medium speed or high speed).
[0064] In some embodiments, the electronic components 500 are in abutment with the lower foot plate 200; or the electronic components 500 are arranged in spaced apart relationship with the lower foot plate 200.
[0065] Based on the base assembly 10 of the above embodiments, the application further provides a fan 01, which comprises the base assembly 10 mentioned in any one of the above embodiments and a fan body 20.
[0066] The fan body 20 is arranged on the upper foot plate 100 and electrically connected to the electronic components 500.
