Description

Technical Field

[0001] This utility model relates to the field of air suspension pump technology, and specifically to an air suspension pump intake structure with multi-angle adjustable air angle. Background Technology

[0002] The air suspension pump is a key component used to adjust the vehicle chassis height. It achieves dynamic adjustment of the vehicle height by controlling the air pressure changes in the air springs, thereby improving driving comfort and handling stability.

[0003] The air intake structure of the air suspension pump consists of two parts: the end cover of the air suspension pump housing and the air intake nozzle connected to the end of the air intake pipe. The air intake of the air suspension pump is achieved by opening an air intake port on the end cover and connecting it with the air intake nozzle. In this conventional air intake structure, the air intake nozzle is usually set with a fixed connection angle at the air intake port position on the end cover in order to avoid sealing problems caused by its own rotation. This makes it impossible to adjust the air intake nozzle to adapt to the actual installation requirements, which can easily lead to problems such as bending of the air intake pipe due to the inability to adjust it to adapt to the connection direction of the air intake pipe. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a multi-angle adjustable air suspension pump air intake structure, which solves the problem that the installation angle of the air intake nozzle on the end cover in the prior art air suspension pump air intake structure cannot be adjusted to meet actual installation requirements.

[0005] To achieve the above objectives, this utility model provides a multi-angle adjustable air intake structure for an air suspension pump. Based on the inherent housing of the air suspension pump, the multi-angle adjustable air intake structure includes an end cap installed at the end of the housing and an air intake nozzle that mates with the end cap; wherein,

[0006] An air inlet is provided on the end cap, and an inwardly protruding limiting protrusion is provided on the lower inner side wall of the air inlet.

[0007] The air inlet is provided with an insertion part that extends downward and can be inserted into the upper part of the air inlet; the lower end of the insertion part is evenly connected with elastic buckles along the circumferential direction, and the lower end of the elastic buckles extends downward past the lower part of the air inlet and snaps outward to the bottom surface of the end cover.

[0008] The limiting protrusion falls between any two adjacent elastic buckles.

[0009] By adopting this technical solution, on the basis of normal insertion between the air inlet nozzle and the air inlet, the connection between the air inlet nozzle and the air inlet is achieved by the fastening of multiple elastic buckles and end caps. Any two of the elastic buckles can cooperate with the limiting protrusion in the air inlet to achieve anti-rotation and prevent damage to the seal. At the same time, different pairs of elastic buckles can be selected to cooperate with the limiting protrusion in the air inlet to change the installation angle of the air inlet to adapt to actual installation needs, and the problem of bending of the air inlet pipe due to fixed installation angle will not occur.

[0010] Furthermore, a limiting ring plate is integrally connected to the air intake, and the limiting ring plate is located on the upper side of the insertion part;

[0011] After the insertion part is inserted into the upper part of the air inlet, the lower end face of the limiting ring plate abuts against the top end face of the end cap corresponding to the top edge of the air inlet.

[0012] By adopting this technical solution, the limiting ring plate can limit the insertion depth of the insertion part, ensure the connection accuracy of the air inlet nozzle, and at the same time ensure that it can cooperate with the elastic buckle plate connected to the lower end of the insertion part to play the role of fixing the air inlet nozzle on the air inlet.

[0013] Furthermore, an annular relief groove is provided on the surface of the insertion part in the circumferential direction, and a sealing ring is sleeved inside the relief groove;

[0014] The outer side of the sealing ring protrudes from the outer wall of the insertion part.

[0015] By adopting this technical solution, a relief groove is set to provide a connection position for the sealing ring, and the sealing ring can be limited and connected to the insertion part. This ensures that the outer side of the sealing ring abuts against the inner side wall of the air inlet after the insertion part is inserted into the air inlet, thereby ensuring the sealing effect after connection.

[0016] Furthermore, the elastic buckle plate is inclined outward from top to bottom, and the lower end face of the elastic buckle plate is inclined upward toward the side that fastens the bottom surface of the end cap;

[0017] In its natural state, the edge of the air inlet is located between the inner and outer edges of the lower end of the elastic buckle plate.

[0018] By adopting this technical solution, the bottom end of the elastic buckle can extend into the air intake in a natural state, and then, under pressure, it can be easily pressed into the air intake through the inclined surface set at its bottom end, and finally can be fastened to the bottom surface of the end cover, thereby reducing the installation difficulty of the air intake nozzle.

[0019] Furthermore, at least two limiting protrusions are provided, and the two limiting protrusions are located on both sides of the same elastic buckle plate.

[0020] By adopting this technical solution, at least two limiting protrusions can complete the limiting of both sides of the same elastic buckle, increasing the anti-rotation effect and thus increasing the connection stability.

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] 1. Based on the normal insertion of the air inlet nozzle and the air inlet port, the connection between the air inlet nozzle and the air inlet port is achieved by the fastening of multiple elastic buckles and end caps. Any two elastic buckles can cooperate with the limiting protrusion in the air inlet port to prevent rotation and prevent damage to the seal. At the same time, different pairs of elastic buckles can be selected to cooperate with the limiting protrusion in the air inlet port to change the installation angle of the air inlet nozzle to adapt to actual installation needs.

[0023] 2. The air inlet nozzle and air inlet are connected by a combination of plug-in and snap-fit, which makes the connection structure simple, convenient and quick. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Please see the appendix Figure 1-2This utility model provides a multi-angle adjustable air intake structure for an air suspension pump. Based on the inherent housing 1 of the air suspension pump, the multi-angle adjustable air intake structure includes an end cap 2 installed at the end of the housing 1 and an air intake nozzle 3 connected to the end cap 2. The end cap 2 has an air inlet 21, and the lower inner side wall of the air inlet 21 is provided with an inwardly protruding limiting protrusion 22. The air intake nozzle 3 is provided with an insertion part that extends downward and can be inserted into the upper part of the air inlet 21. The lower end of the insertion part is evenly connected with elastic buckles 32 along the circumference. The lower end of the elastic buckles 32 extends downward past the lower part of the air inlet 21 and is fastened outward to the bottom surface of the end cap 2. The limiting protrusion 22 falls between any two adjacent elastic buckles 32.

[0031] Based on the normal insertion of the air inlet 3 and the air inlet 21, the connection between the air inlet 3 and the air inlet 21 is achieved by the fastening of multiple elastic buckles 32 and the end cap 2. Any two elastic buckles 32 can cooperate with the limiting protrusion 22 in the air inlet 21 to achieve anti-rotation and prevent damage to the seal. At the same time, different pairs of elastic buckles 32 can be selected to cooperate with the limiting protrusion 22 in the air inlet 21 to change the installation angle of the air inlet 3 to adapt to the actual installation requirements, and the problem of bending of the air intake pipe due to the fixed installation angle will not occur.

[0032] Furthermore, the number of flexible snap-on plates 32 can be changed to adapt to installation requirements at specific angles, as shown in the attached figure. Figure 4 The illustration shows the installation of the air intake nozzle 3 at several specific angles. The specific installation angle depends on the included angle between adjacent elastic buckles 32. For example, if the included angle between adjacent elastic buckles 32 is 30°, the installation angle of the air intake nozzle 3 can be selected from 30°, 60°, 90°, 120°, 150°, 180°, 210°, 240°, 270°, 300° and 330° by cooperating with different adjacent elastic buckles 32 and limiting protrusions 22.

[0033] Please see the appendix Figure 1 A limiting ring plate 31 is integrally connected to the air inlet 3. The limiting ring plate 31 is located on the upper side of the insertion part. After the insertion part is inserted into the upper part of the air inlet 21, the lower end face of the limiting ring plate 31 abuts against the top face of the end cap 2 corresponding to the top edge of the air inlet 21. The limiting ring plate 31 can limit the insertion depth of the insertion part, ensure the connection accuracy of the air inlet 3, and at the same time ensure that it can cooperate with the elastic buckle plate 32 connected to the lower end of the insertion part to play the role of fixing the air inlet 3 on the air inlet 21.

[0034] Please see the appendix Figure 1 and 3An annular relief groove 34 is provided on the surface of the insertion part along the circumference, and a sealing ring 33 is fitted inside the relief groove 34. The outer side of the sealing ring 33 protrudes from the outer side wall of the insertion part. The relief groove 34 provides a connection position for the sealing ring 33 and allows the sealing ring 33 to be limited and connected to the insertion part, thereby ensuring that the outer side of the sealing ring 33 abuts against the inner side wall of the air inlet 21 after the insertion part is inserted into the air inlet 21, thus ensuring the sealing effect after connection.

[0035] Please see the appendix Figure 1 and 3 The elastic buckle 32 is inclined outward from top to bottom, and the lower end face of the elastic buckle 32 is inclined upward towards the bottom surface of the end cover 2. In the natural state, the edge of the air inlet 21 is located between the inner and outer edges of the lower end of the elastic buckle 32. This allows the lowermost end of the elastic buckle 32 to extend into the air inlet 21 in the natural state, and then, under pressure, it can be easily pressed into the air inlet 21 through the inclined surface at its lower end, and finally be fastened to the bottom surface of the end cover 2, thereby reducing the installation difficulty of the air inlet 3.

[0036] Please see the appendix Figure 2 At least two limiting protrusions 22 are provided, and the two limiting protrusions 22 are located on both sides of the same elastic buckle 32; at least two limiting protrusions 22 can complete the limiting on both sides of the same elastic buckle 32, increasing the anti-rotation effect to increase the connection stability.

[0037] Furthermore, the limiting protrusions 22 can also be set in groups of two, and multiple groups can be set along the lower part of the inner wall of the air inlet 21, which can further increase the anti-rotation effect and increase the connection stability.

[0038] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
