[0002] In order to reduce the noise generated by vibration during operation of the bladeless fan in the prior art, an elastic shock-absorbing member is generally provided at the connection between the power component and the base to prevent the power component from directly contacting the base with the vibration and generating collision noise.

[0003] However, there is generally a line connected between the power assembly and the base. During elastic shock absorption, a certain relative movement will occur between the power assembly and the base, which may easily cause wear between the line connected to both the power assembly and the base and the shell wall of the power assembly and the shell wall of the base, thus affecting the service life of the line. Summary of the invention

At the preset installation position, the line is bridged in a "U"-shaped structure above the first wall and the second wall.

[0008] Furthermore, the shock absorbing assembly includes: a bracket, which is sandwiched between the base and the power assembly; and an elastic member, which is supported between the lower end surface of the power assembly and the upper end surface of the bracket.

[0009] Furthermore, the base is an annular groove body with an opening at the top, and a supporting edge is protrudingly formed on the inner side of the groove wall, and the bracket is arranged on the supporting edge.

[0010] Furthermore, a first buffer is provided between the bracket and the supporting edge.

[0011] Furthermore, the first buffer member is integrally formed on the bracket and / or the supporting edge.

[0012] Furthermore, at least one protrusion is protrudingly provided on the peripheral surface of the bracket, and a sliding groove adapted to the protrusion is provided on the inner side of the groove wall of the base along the height direction of the base assembly.

[0013] Furthermore, a locking structure is provided at the matching position between the upper end surface of the protrusion and the slide groove.

[0014] Furthermore, the elastic member is configured as a compression spring.

[0015] Furthermore, the shock absorbing assembly also includes a compression spring bracket, which is arranged on the end surface of the bracket facing the power assembly, the compression spring is sleeved on the compression spring bracket, and a bracket mounting groove is correspondingly arranged on the power assembly.

[0016] Furthermore, the compression spring bracket is a columnar buckle structure having two elastic arms arranged opposite to each other and a clamping head formed at the upper end of the elastic wall.

[0017] Furthermore, the shock absorbing assembly further comprises a plurality of positioning columns, which are arranged on the end surface of the bracket facing the power assembly, and the power assembly is correspondingly provided with positioning grooves.

[0018] Furthermore, the upper end surface of the positioning column is located above the compression spring bracket.

[0019] Furthermore, a limit block is also provided at the upper end of the power assembly, and the limit block is used in conjunction with the first limit surface on the head assembly to limit the pop-up height of the power assembly under the action of the shock absorbing assembly.

[0020] Furthermore, at the preset installation position, there is a distance a between the limit block and the first limit surface, and there is a distance b between the clamping surface of the clamp head and the second limit surface on the power assembly, and both satisfy that a is less than b.

[0021] The present invention also provides a fan, comprising any one of the base components described above.

[0022] Furthermore, the fan is a bladeless fan.

[0023] The technical solution of the present invention has the following advantages:

[0024] 1. The base assembly in the present invention includes a base, on which a power assembly is arranged, a shock absorbing assembly is arranged between the base and the power assembly, the power assembly and the base have mutually embedded parts, at which a first wire clamping part and a second wire clamping part are respectively arranged on the same side of the base and the power assembly; and a wire passing groove is arranged above the first wire clamping part; wherein in the height direction of the base assembly, the upper end surface of the second wire clamping part is above the bottom of the wire passing groove.

[0025] In the present invention, one end of the line connected between the base and the power assembly is fixed to the base by a first line clamping part, and the other end is fixed to the power assembly by a second line clamping part. During the vibration process, the base is fixed and the power assembly vibrates up and down relative to the base. During the up and down movement of the power assembly, the upper end surface of the second line clamping part is located above the bottom of the line groove, which ensures that the line is continuously bent and unfolded in the line groove under the drive of the power assembly, and no pulling force is generated on the line, thereby effectively avoiding the risk of wear and breakage between the line and the base and the power assembly.

[0026] 2. In the base assembly of the present invention, the first wire clamping part is arranged on the outer side surface of the first wall, and the second wire clamping part is arranged on the inner side surface of the second wall. At the preset installation position, the line is in a "U"-shaped structure bridging the upper position of the first wall and the second wall. The above-mentioned "U"-shaped line structure itself can ensure that the bending radius of the line is larger when bending and unfolding. The larger bending radius can reduce the stress concentration problem of the line at the bending point, thereby increasing the service life of the line.

[0027] 3. In the base assembly of the present invention, a first buffer is provided between the bracket and the supporting edge, and the first buffer can avoid the increase of contact noise due to direct hard contact between the bracket and the supporting edge during vibration.

[0028] 4. In the base assembly of the present invention, at least one protrusion is protruding from the circumferential surface of the bracket, and a slide groove adapted to the protrusion is provided on the inner side of the groove wall of the base along the height direction of the base assembly. The protrusion and the slide groove can play a role in guiding the installation, which can improve the efficiency of assembly and effectively prevent the circumferential rotation of the bracket.

[0029] 5. In the base assembly of the present invention, a locking structure is provided at the matching position between the upper end surface of the protrusion and the slide groove, which further enhances the reliability of the fixation between the bracket and the base.

[0030] 6. The upper end surface of the positioning column in the base assembly of the present invention is above the compression spring bracket. When the power assembly moves downward under the action of vibration and the vibration amount is too large, it can be ensured that the upper end surface of the positioning column first contacts the bottom of the positioning groove on the power assembly to prevent the upper end of the compression spring bracket from directly contacting the power assembly and causing breakage.

[0031] 7. In the base assembly of the present invention, at the preset installation position, there is a spacing a between the limit block and the first limit surface, and there is a spacing b between the clamping surface of the clamp head and the second limit surface on the power assembly, and both satisfy that a is less than b. This ensures that when the power assembly moves upward under the action of vibration and the vibration amount is too large, the limit block can be ensured to contact the first limit surface first, preventing the clamping surface of the clamp head from directly contacting the second limit surface on the power assembly and causing breakage.

[0051] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] Example 1

[0056] like Figures 1 to 10 As shown, a base assembly provided for this embodiment includes a base 1, on which a power assembly 2 is arranged, a shock absorbing assembly 3 is arranged between the base 1 and the power assembly 2, and the power assembly 2 and the base 1 have a mutually embedded portion, at which a first wire clamping portion 11 and a second wire clamping portion 21 are respectively arranged on the same side of the base 1 and the power assembly 2; and a wire passing groove 12 is arranged above the first wire clamping portion 11; wherein in the height direction of the base assembly, the upper end surface of the second wire clamping portion 21 is above the bottom of the wire passing groove 12.

[0057] The base assembly in this embodiment is used for a bladeless fan, and is also applicable to other electrical products that require shock absorption on the base assembly, such as cabinet air conditioners.

[0058] It should also be noted that the slot size of the above-mentioned wire slot 12 should be larger than the wire diameter of the wire 7 to ensure that the wire 7 can move flexibly in the wire slot 12.

[0059] In this embodiment, the line 7 connected between the base 1 and the power assembly 2 is fixed to the base 1 by the first line clamping part 11 at one end, and fixed to the power assembly 2 by the second line clamping part 21 at the other end. During the vibration process, the base 1 is fixed, and the power assembly 21 vibrates up and down relative to the base 1. During the up and down movement of the power assembly 2, the upper end surface of the second line clamping part 21 is located above the bottom of the line groove 12, thereby ensuring that the line 7 is continuously bent and unfolded in the line groove 12 under the drive of the power assembly 2, and no pulling force is generated on the line 7, thereby effectively avoiding the risk of wear and breakage between the line 7 and the base 1 and the power assembly 2.

[0060] like Figure 1 As shown in, the embedded portion in this embodiment includes a first wall 13 formed on the base 1 and a second wall 22 formed on the power assembly 2, the second wall 22 is embedded in the first wall 13, the first wire clamping portion 11 and the second wire clamping portion 21 are respectively installed on the first wall 13 and the second wall 22, specifically, the first wire clamping portion 11 is installed on the outer side of the first wall 13, and the second wire clamping portion 22 is installed on the inner side of the second wall 22. At the preset installation position, the line is in a "U"-shaped structure bridging the upper position of the first wall 13 and the second wall 22. The above-mentioned "U"-shaped line structure itself can ensure that the bending radius of the line 7 is larger when bending and unfolding. The larger bending radius can reduce the stress concentration problem of the line 7 at the bending point, thereby increasing the service life of the line 7.

[0061] In this embodiment, the first wire clamping portion 11 and the second wire clamping portion 21 are commonly used wire groove structures, and the wire 7 is pressed into the wire groove by interference fit to achieve fixation.

[0062] like Figure 2 As shown, the structural composition of the shock absorbing assembly 3 is shown. The shock absorbing assembly 3 includes: a bracket 31, which is clamped between the base 1 and the power assembly 2. The bracket 31 in this embodiment is an annular structure. Specifically, the base 1 is an annular groove body with an opening on the top, and a supporting edge 14 is protruded on the inner side of the groove wall. The bracket 31 is fitted on the supporting edge 14. The above-mentioned structural method installs the bracket inside the base 1, which saves space while allowing the bracket 31 to be effectively constrained by the base 1, thereby increasing the stability of the installation of the bracket 3.

[0063] During installation, in order to prevent the bracket 31 from directly contacting the supporting edge 14 and generating noise during vibration, a first buffer 4 is provided between the bracket 31 and the supporting edge 14. The first buffer 4 is a commonly used rubber pad structure.

[0064] Furthermore, in this embodiment, the first buffer component 4 is integrally formed on the supporting edge 14, which simplifies the installation process of the first buffer component 4, and the integrated molding process can effectively ensure the flatness of the surface contact of the first buffer component 4, thereby effectively controlling the gap error and ensuring the shock absorption effect.

[0065] Of course, in some other embodiments, the first buffer member 4 may also be integrally formed on the bracket 31 , which has the same technical effect.

[0066] Combination Figure 7 and Fig. 9 , shows the installation method of the bracket 31 and the base 1 in this embodiment. Specifically, at least one protrusion 33 is protruded on the peripheral surface of the bracket 31, and one is provided in this embodiment. The inner side of the groove wall of the base 1 is formed with a slide groove 15 adapted to the protrusion 33 along the height direction of the base assembly. The protrusion 33 and the slide groove 15 can play a role in guiding the installation, improve the efficiency of assembly, and effectively prevent the circumferential rotation of the bracket 31.

[0067] Furthermore, a rib 16 is processed on the bottom surface of the slide groove 15, which can ensure the tightness of the contact between the protrusion 33 and the slide groove 15 and prevent the generation of installation gap.

[0068] Furthermore, in order to enhance the strength of the connection between the bracket 31 and the base 1, a locking structure 5 is provided at the joint between the upper end surface of the protrusion 33 and the slide groove 15. The above-mentioned locking structure 5 is a commonly used screw locking structure and will not be described in detail here.

[0069] Of course, in some other embodiments, the locking structure 5 can also be implemented in the form of snap-on locking, which can improve the efficiency of assembly.

[0070] In some other embodiments, the number of the protrusions 33 can be multiple, which can enhance the strength of the fixed installation.

[0071] Furthermore, when there are multiple protrusions 33 , the protrusions 33 are arranged at equal intervals along the circumference of the bracket 31 to ensure the consistency of force applied to each protrusion 33 and to ensure its service life.

[0072] like Figure 2 and Figure 3 As shown in FIG. 3 , an elastic member 32 is also installed on the bracket 31 and supported between the lower end surface of the power assembly 2 and the upper end surface of the bracket 31 . In this embodiment, the elastic member 32 is constructed as a compression spring, which is low in cost and easy to process.

[0073] In order to achieve easy assembly of compression springs, Figure 6 and Figure 7 As shown, the shock absorbing assembly 3 also includes a compression spring bracket 34, which is integrally formed on the end surface of the bracket 31 facing the power assembly 2. The compression spring is sleeved on the compression spring bracket 34, and a bracket mounting groove 23 is correspondingly provided on the power assembly 2. Specifically, the compression spring bracket 34 in this embodiment is a columnar buckle structure, which has two elastic arms 341 arranged opposite to each other and a clamping head 342 formed on the upper end of the elastic wall 341. When the compression spring is installed, the two elastic arms 341 are pressed toward the middle so that the compression spring is connected to the compression spring bracket through the clamping head 342. When the connection is in place, the elastic arm 341 is reset, and the compression spring is limited to the compression spring bracket 34 by the clamping head 342. The installation is simple and convenient, and it is ensured that the compression spring will not fall out, which provides convenience for the subsequent assembly process.

[0074] There are four compression spring brackets 34 in this embodiment, which are evenly spaced along the circumference of the bracket 31 , which can effectively ensure that a uniform supporting force is provided to the power assembly 2 .

[0075] The number of the intermediate compression spring brackets 34 can be reasonably adjusted according to the actual vibration conditions and the self-gravity of the power assembly 2 .

[0076] like Figure 6 and Figure 8 As shown, the shock absorbing assembly 3 also includes a plurality of positioning columns 35, which are installed on the end face of the bracket 31 facing the power assembly 2. The power assembly 2 is correspondingly processed with a positioning groove 24. The arrangement of the positioning columns 35 not only facilitates the installation, but also plays a role in limiting the circumferential rotation, thereby protecting the shear force generated by the circumferential rotation from causing damage to the compression spring bracket 34.

[0077] like Fig.10The upper end surface of the positioning column 35 is above the compression spring bracket 34, and there is a height difference h. When the power component 2 moves downward under the action of vibration and the vibration amount is too large, it can be ensured that the upper end surface of the positioning column 35 first contacts the bottom of the positioning groove on the power component 2 to prevent the upper end of the compression spring bracket 34 from directly contacting the power component 2 and causing breakage.

[0078] like Figure 5 and Fig.10 As shown, a limit block 25 is also provided at the upper end of the power assembly 2. The limit block 25 is used in conjunction with the first limit surface 61 on the head assembly 6 to limit the bounce height of the power assembly 2 under the action of the shock absorbing assembly 3. At the preset installation position, there is a spacing a between the limit block 25 and the first limit surface 61, and there is a spacing b between the clamping surface of the clamp head 342 and the second limit surface 26 on the power assembly 2, and both satisfy that a is less than b. This ensures that when the power assembly 2 moves upward under the action of vibration and the vibration amount is too large, the limit block 25 can be ensured to contact the first limit surface 61 first, preventing the clamping surface of the clamp head from directly contacting the second limit surface on the power assembly and causing breakage.

[0079] Example 2

[0080] This embodiment provides a fan having the base assembly described in the above embodiment 1 and having all its technical advantages, which will not be described in detail here.

[0081] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
