Description

Technical Field

[0001] This utility model relates to the field of automotive transmission maintenance technology, and in particular to a transmission cleaning and oil changing machine. Background Technology

[0002] After prolonged use, the performance of the transmission fluid in an automatic transmission deteriorates. If not replaced in time, this can cause malfunctions in the automatic transmission. An automatic transmission cleaning and oil change machine is a device that automates the oil change and cleaning of a car's transmission. Currently, automatic transmission cleaning and oil change machines may preheat the new fluid being added to the transmission during the oil change to avoid temperature differences. However, in existing technology, the heater is mainly installed in the enclosed space inside the automatic transmission cleaning and oil change machine's casing. Because it requires inlet and outlet pipes at both ends, the installation and internal wiring are rather messy, reducing the efficiency of heater assembly and disassembly and affecting the heater's effectiveness within the machine's casing. Therefore, this paper proposes a new type of automatic transmission cleaning and oil change machine. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides, for example Figures 1-4 The image shows a gearbox cleaning and oil change machine.

[0034] Example 1: As Figures 1-4 As shown, the device includes a housing 100, a front baffle 101, a heater 200, and a fixing component. The front baffle 101 is fixedly installed inside the housing 100. The front baffle 101 has a perforated hole 102 connecting the front and rear sides of the front baffle 101. The heater 200 is inserted into the perforated hole 102 on the front baffle 101, and the back of the heater 200 extends through the perforated hole 102 to the back of the front baffle 101. The heater 200 is wider at the front and narrower at the back, and the shape of the perforated hole 102 matches the shape of the back of the heater 200. The fixing component is disposed between the heater 200 and the front baffle 101, and connects the heater 200 and the front baffle 101 respectively, so that the heater 200 is relatively fixed to the front baffle 101 through the fixing component.

[0035] In this embodiment, the heater 200 has a body portion 201 and a protrusion 202 extending rearward integrally from the back of the body portion 201. The body portion 201 is located on the front side of the front baffle 101 of the chassis and partially abuts against the front of the front baffle 101. The protrusion 202 is adapted to the shape of the perforation 102 and passes through the perforation 102, exposing the rear side of the front baffle 101. Specifically, the front baffle 101 is installed on the front side inside the housing 100. The perforation 102 on it allows the heater 200 to be positioned at this location via the protrusion 202. Simultaneously, the shape of the heater 200 (wider at the front and narrower at the rear) (protrusion 202) allows it to be embedded in the perforation 102 and extend rearward into the housing 100, reducing the space occupied by the heater 200 on the front of the front baffle 101. The body portion 201 abuts against the front of the front baffle 101, and the protrusion... The cooperation between 202 and the main body 201 not only helps to position the heater 200, but also maintains its installation stability. It also avoids the disadvantage that the heater 200 protrudes too much and comes into contact with the inside of the housing 100, which can easily lead to heat loss. This makes the layout of the heater 200 inside the housing 100 more reasonable. At the same time, the fasteners are used to fix the heater 200 to the front panel 101 of the chassis, ensuring that the heater 200 is installed firmly on the front panel 101 of the chassis. This also makes the installation and removal of the heater 200 more convenient.

[0036] Furthermore, the transmission cleaning and oil change machine also includes a reservoir, a valve block assembly, an inlet pipe, and an outlet pipe. The valve block assembly is connected to the inlet pipe, the outlet pipe, and the reservoir. The reservoir is located on the rear side of the front baffle 101 of the chassis, while the valve block assembly, the inlet pipe, and the outlet pipe are all located on the front side of the front baffle 101. These components work together to enable the transmission cleaning and oil change machine to perform oil changes and cleaning of the transmission, which will not be described in detail here.

[0037] Because the installation structure of the heater 200 in this application can save a significant amount of space, the heater 200 can be installed vertically. The lower end of the heater 200 has an inlet for connecting to a liquid storage tank, and the upper end has an outlet connected to an outlet pipe. The other end of the outlet pipe is used to connect to the vehicle's transmission. The vertical installation of the heater 200 meets the placement standards for its inlet and outlet, resulting in more efficient heating and a neater piping appearance.

[0038] like Figure 3 and Figure 4As shown, the fixing component includes a first heater fixing plate 103, which includes a first fixing part 1031 and a second fixing part 1032. The middle part of the first fixing part 1031 is bent along the thickness direction relative to its two ends to form a recessed groove structure. The protrusion 202 is inserted and fixed into the recessed groove structure. The second fixing part 1032 is connected to one end of the first fixing part 1031 and extends along the length direction of the first fixing part 1031. The second fixing part 1032 is used to connect to the front baffle 101 of the chassis to fix the heater 200. Furthermore, there are two second fixing parts 1032, which are bent and connected to the two ends of the first fixing part 1031 respectively to improve the stability and balance of the heater 200 fixing.

[0039] In one embodiment, the front baffle 101 of the chassis has two screw holes near the perforated hole 102; the fastener also includes two locking screws 104, which are respectively inserted into two second fixing parts 1032. The outer wall of one locking screw 104 passes through one second fixing part 1032 and is threadedly connected to the screw hole on the front baffle 101 of the chassis. Of course, this embodiment is only a preferred embodiment of the present invention. In other embodiments of the present invention, the connection method between the second fixing part 1032 and the front baffle 101 of the chassis is not limited to this, such as gluing or welding.

[0040] In this embodiment, recesses 1011 are provided on the inner walls of both sides of the perforated hole 102 at positions corresponding to the side walls of the first heater fixing plate 103. The outer walls of both sides of the first fixing part 1031 are movably inserted into the recesses 1011 on the inner walls of the perforated hole 102. That is, the recesses 1011 make way for the outer walls of both sides of the first fixing part 1031, so that the protrusion 202 of the heater 200 contacts the inner wall of the perforated hole 102 as much as possible, thereby improving the installation stability of the heater 200.

[0041] Furthermore, the recessed groove structure is adapted to the shape of the back side of the heater 200; the depth of the recessed groove structure is less than or equal to the thickness of the protrusion 202. That is, the depth of the recessed groove structure is slightly less than or equal to the thickness of the protrusion 202, with an error of ±5mm. This design ensures that the bottom wall of the recessed groove structure abuts against the protrusion 202, thereby improving the installation stability of the heater 200.

[0042] In one implementation, the bottom wall of the recessed groove structure is provided with a fixing hole, and the fixing component may also include a stabilizing screw. The stabilizing screw passes through the fixing hole and is threaded to the protrusion 202, thereby realizing the installation connection between the heater 200 and the first heater fixing plate 103, making it convenient to install and disassemble the heater 200.

[0043] In one embodiment, the front baffle 101 of the chassis may be provided with a clearance hole corresponding to the main body 201, thereby reducing the contact between the front baffle 101 of the chassis and the main body 201, reducing the heat conduction between the two, and thus reducing the heating loss; and the clearance hole may be set close to and connected to the hollow hole 102, which makes the processing more convenient and reduces the manufacturing difficulty.

[0044] Example 2: Refer to Figure 5 The difference between this embodiment and Embodiment 1 is that the fixing component includes a second heater fixing plate 105. The end of the second heater fixing plate 105 near the heater 200 is bent downwards to be parallel to the side wall of the heater 200, and an easy-to-remove structure is provided between the second heater fixing plate 105 and the side wall of the heater 200. The locking screw 104 is movably inserted into the end of the second heater fixing plate 105 away from the heater 200, and the outer wall of the locking screw 104 passes through the second heater fixing plate 105 and is threadedly connected to the screw hole opened on the front baffle 101 of the chassis. Compared with Embodiment 1, in this embodiment, the second heater fixing plate 105 is designed as a right-angle bent L-shape. The side wall of the second heater mounting plate 105 is easily detached and snapped together with the side wall of the heater 200. Then, the second heater mounting plate 105 is inserted into the cutout hole 102 through the heater 200, which blocks the side wall of the heater 200, preventing the second heater mounting plate 105 from being removed from the side wall of the heater 200. Then, the second heater mounting plate 105 is connected and fixed to the front panel 101 of the chassis with the locking screw 104. This satisfies the requirement for a detachable connection between the heater 200 and the front panel 101 of the chassis, while also making it easy to disassemble and assemble without the need for re-tightening the second heater mounting plate 105 to the heater 200.

[0045] The easily detachable structure includes a polygonal hole 106 and a polygonal protrusion 107. The polygonal hole 106 is located on the side wall of the bent end of the second heater fixing plate 105. The polygonal protrusion 107 is fixedly connected to the side wall of the heater 200 and protrudes outward. The second heater fixing plate 105 is movably inserted into the outer wall of the polygonal protrusion 107 through the polygonal hole 106. The second heater fixing plate 105 is inserted into the polygonal protrusion 107 on the side wall of the heater 200 through the polygonal hole 106 on the side wall. After the heater 200 is inserted from the hollow hole 102, the blocking effect of the inner wall of the hollow hole 102 prevents the second heater fixing plate 105 from separating from the polygonal protrusion 107 (the side wall of the hollow hole 102 also has a recessed part 1011 with the same wall thickness as the second heater fixing plate 105). Then, the second heater fixing plate 105 is fixed to the front panel 101 of the chassis by the locking screw 104 to ensure the stable installation of the heater 200 on the front panel 101 of the chassis.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
