DETAILED DESCRIPTION

[0039] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0040] The components of the embodiments of the present application generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed, but merely represents the selected embodiments of the present application.

[0041] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0042] In the description of the present application, 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 application 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 application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0043] In the description of this application, 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 this application can be understood according to specific circumstances.

[0044] Refer to the following Figures 1 to 16 A variable height contact rail support assembly according to some embodiments of the present application is described.

[0045] Embodiment 1

[0046] See also Figure 1 As shown, an embodiment of the present application provides a variable height contact rail support assembly, comprising: a first support member 1, a second support member 2 and an elastic member 3;

[0047] Wherein, the first supporting member 1 and the second supporting member 2 are slidably connected along the height direction;

[0048] An elastic member 3 is arranged between the first supporting member 1 and the second supporting member 2, one end of the elastic member 3 abuts against the first supporting member 1, and the other opposite end of the elastic member 3 abuts against the second supporting member 2; the second supporting member 2 is formed with a clamping installation groove 21 for clamping the contact rail; the second supporting member 2 is formed with a clamping installation portion 22 for clamping the protective cover.

[0049] Specifically, the normal usage status of the variable height contact rail support assembly is as follows: the variable height contact rail support assembly is clamped on the outside of the contact rail through the second support member 2, and the protective cover is clamped on the first support member 1, and the cover is located on the outside of the first support member 1 and the second support member 2. The first support member 1 is located above the second support member 2 and is lifted up by the elastic member 3. In the normal assembly state, the gap between the first support member 1 and the second support member 2 is about 5 mm (changeable).

[0050] In the above state, when the protective cover needs to be removed, the protective cover can be directly pressed down, and the protective cover presses down the first support member 1, and then the first support member 1 presses down the elastic member 3, and the elastic member 3 produces elastic deformation, thereby moving the protective cover downward, achieving the effect of the snap-on mounting portion 22 of the second support member 2 being disengaged from the protective cover slot, and then the protective cover can be removed.

[0051] It can be seen that the above operation is simple, convenient, time-saving and labor-saving, and avoids the problems that occurred in the previous barbaric construction, thereby playing the role of protecting the protective cover.

[0052] In addition, since the first support member 1 and the second support member 2 are slidably connected along the height direction of the variable height contact rail support assembly, it is only necessary to change the compression amount of the compression elastic member 3 to adapt to protective covers of different height sizes. It is more practical and has a wider range of applications. Moreover, because the assembly height of the first support member 1 can be adjusted accordingly by adjusting the height of the elastic member 3, the first support member 1 and the protective cover are more closely matched. When encountering piston wind, the protective cover is not easy to shake up and down, and is not easy to make abnormal noises, which makes the protective cover, the contact rail and the variable height contact rail support assembly less prone to wear.

[0053] In this embodiment, preferably, Figures 1 to 4 As shown, the second supporting member 2 is formed with a cylindrical plug-in portion 23 , and the first supporting member 1 is formed with a circular plug-in groove 11 .

[0054] According to the structure described above, it can be known that the plug-in portion 23 is inserted into the plug-in slot 11, and specifically, the two are connected by damping sliding, so as to adapt to protective covers of different heights and sizes.

[0055] Among them, preferably, the number of the plug-in parts 23 is two, and the two plug-in parts 23 are arranged in sequence along the length direction of the first support member 1. Correspondingly, the number of the plug-in slots 11 is also two, and the two plug-in slots 11 are arranged in sequence along the length direction of the second support member 2.

[0056] In this embodiment, preferably, Figure 4As shown, the first supporting member 1 forms a limiting groove 14 (this limiting groove 14 is a circular groove, of course not limited to this), one end of the elastic member 3 is clamped in the limiting groove 14, and the other end of the elastic member 3 abuts against the second supporting member 2.

[0057] The above assembly structure can effectively prevent the elastic member 3 from being separated from between the first supporting member 1 and the second supporting member 2 .

[0058] Among them, preferably, the number of the elastic components 3 is two, and the two elastic components 3 are arranged in sequence and at intervals along the length direction of the variable height contact rail support assembly, and the two elastic components 3 correspond to the two plug-in parts 23 one by one and are arranged in a group.

[0059] In this embodiment, preferably, Figure 1 As shown, the first supporting member 1 includes a main body 15 and a supporting portion 16 connected to the main body 15 , the supporting portion 16 has an arc-shaped supporting surface, and a reinforcing rib 17 is provided between the main body 15 and the supporting portion 16 .

[0060] The second support member 2 includes a support beam 27 and two clamping parts 28 connected to two opposite ends of the support beam 27, the three of which are arranged to form a clamping installation groove 21 for installing the contact rail, wherein the support beam 27 is plate-shaped. The two clamping parts 28 are buckles, and they themselves are formed with grooves, and the reinforcing ribs 17 are arranged in the grooves.

[0061] In this embodiment, preferably, except for the elastic member 3, the remaining components of the variable height contact rail support assembly are formed of fiber reinforced thermosetting materials such as SMC materials, BMC materials, polyurethane prepreg and polyurethane SMC materials, or are formed of fiber reinforced thermoplastic materials such as PP and PE materials, but are not limited to the above.

[0062] Embodiment 2

[0063] See also Figure 5 As shown, an embodiment of the present application provides a variable height contact rail support assembly, comprising: a first support member 1, a second support member 2 and an elastic member 3;

[0064] Wherein, the first supporting member 1 and the second supporting member 2 are slidably connected along the height direction;

[0065] An elastic member 3 is arranged between the first supporting member 1 and the second supporting member 2, one end of the elastic member 3 abuts against the first supporting member 1, and the other opposite end of the elastic member 3 abuts against the second supporting member 2; the second supporting member 2 is formed with a clamping installation groove 21 for clamping the contact rail; the second supporting member 2 is formed with a clamping installation portion 22 for clamping the protective cover.

[0066] Further, preferably, Figure 8 and Fig. 9 As shown, the second support member 2 is formed with a V-shaped plug-in portion 23, and the opening of the V-shaped plug-in portion 23 faces the side of the first support member 1. Correspondingly, the first support member 1 is formed with a V-shaped plug-in groove 11, which serves as an installation guide and assembles the first support member 1 and the second support member 2 together.

[0067] And if Figures 5 to 9 As shown, the variable height contact rail support assembly provided in the present application is also provided with the following positioning structure:

[0068] A slot 231 extending along the height direction of the plug-in portion 23 is formed on the side thereof; the variable height contact rail support assembly also includes a limiting member 4, which is passed through the second support member 2, and a partial structure of the limiting member 4 is located in the plug-in slot 11 of the first support member 1 and is clamped in the slot 231 of the plug-in portion 23; the limiting member 4 is fixedly connected to the first support member 1 by a locking member 5 sleeved thereon.

[0069] The limiting member 4 is preferably a fastening bolt, and correspondingly, the locking member 5 is a fastening nut, which will be used as an example below.

[0070] It can be known from the above description that the use of the limiting member 4 and the locking member 5 mainly ensures that the first supporting member 1 and the second supporting member 2 are in a connected state to avoid separation of the two.

[0071] Furthermore, since a part of the structure of the limiting member 4 slides along the slot 231 and cooperates with different compression amounts of the elastic member 3, it can adapt to protective covers of different heights.

[0072] Further, preferably, Figure 8 As shown, the first support member 1 forms a limiting groove 14 (this limiting groove 14 is a circular groove, of course, not limited to this), one end of the elastic member 3 is clamped in the limiting groove 14, and the other end of the elastic member 3 is against the second support member 2, which can effectively prevent the elastic member 3 from detaching from between the first support member 1 and the second support member 2.

[0073] Among them, preferably, Figure 5 As shown, the V-shaped plug-in portion 23, the V-shaped plug-in groove 11, the card groove 231, the limiting member 4 and the locking member 5 exist as a group of structures. Correspondingly, two groups can be set and spaced apart along the length direction of the variable height contact rail support assembly.

[0074] The structures of the first supporting member 1 and the second supporting member 2 refer to the first embodiment, and will not be described in detail here.

[0075] In combination with the above structure, the operation of removing the protective cover by means of the variable height contact rail support assembly is as follows:

[0076] In the normal assembly state, when the protective cover needs to be removed, the protective cover can be directly pressed down, and the protective cover presses down the first support member 1 (that is, at this time the limiting member 4 can slide along the slot 231), and then the first support member 1 presses down the elastic member 3, and the elastic member 3 produces elastic deformation, thereby moving the protective cover downward, achieving the effect of the clamping installation part 22 of the second support member 2 being separated from the protective cover slot, and then the protective cover is removed.

[0077] It can be seen that the above operation is simple, convenient, time-saving and labor-saving, and avoids the problems that occurred in the previous barbaric construction, thereby playing a role in protecting the protective cover. For other beneficial technical effects, please refer to Example 1, which will not be described in detail here.

[0078] Embodiment 3

[0079] See also Fig.10 As shown, an embodiment of the present application provides a variable height contact rail support assembly, comprising: a first support member 1, a second support member 2 and an elastic member 3;

[0080] Wherein, the first supporting member 1 and the second supporting member 2 are detachably connected;

[0081] An elastic member 3 is arranged between the first supporting member 1 and the second supporting member 2, one end of the elastic member 3 abuts against the first supporting member 1, and the other opposite end of the elastic member 3 abuts against the second supporting member 2; the second supporting member 2 is formed with a clamping installation groove 21 for clamping the contact rail; the second supporting member 2 is formed with a clamping installation portion 22 for clamping the protective cover.

[0082] Further, preferably, Fig.10 and Fig.11 As shown, the first supporting member 1 is formed with a clamping portion 12, and the second supporting member 2 is formed with a clamping groove portion 25. The clamping portion 12 can be clamped in the clamping groove portion 25, that is, the first supporting member 1 and the second supporting member 2 are connected by snap-fit, which is convenient for processing and manufacturing, and extremely easy to install and disassemble.

[0083] Further, preferably, Fig.10 As shown, two clamping portions 12 are formed at both ends of the first support member 1, and the two clamping portions 12 are staggered along the length direction of the first support member 1 at the opposite two sides of the first support member 1, that is, in the normal assembly state, the first support member 1 and the second support member 2 are ensured to be in a connected state, and since the size design of the clamping portion 12 is reasonable, it is in a sliding connection with the slot portion 25, so it only needs to change the compression amount of the elastic member 3 to adapt to protective covers of different heights.

[0084] Further, preferably, Fig.10 As shown, the first support member 1 forms a limiting groove 14 (this limiting groove 14 is an open circular groove, but is certainly not limited to this), one end of the elastic member 3 is clamped in the limiting groove 14, and the other end of the elastic member 3 is against the second support member 2, which can effectively prevent the elastic member 3 from detaching from between the first support member 1 and the second support member 2.

[0085] Further, preferably, Fig.10 and Fig.11 As shown, there are two elastic components 3, and the two elastic components 3 are sequentially spaced apart along the length direction of the variable height contact rail support assembly.

[0086] A reinforcing rib 17 is formed on the top end surface of the second supporting member 2 close to the first supporting member 1 , specifically a Z-shaped reinforcing rib 29 , which plays a reinforcing role and prevents deformation, and the Z-shaped reinforcing rib 29 effectively avoids two elastic members 3 arranged at intervals.

[0087] The structures of the first supporting member 1 and the second supporting member 2 refer to the first embodiment, and will not be described in detail here.

[0088] In combination with the above structure, the operation of removing the protective cover by means of the variable height contact rail support assembly is as follows:

[0089] In the normal assembly state, when the protective cover needs to be removed, the protective cover can be directly pressed down, and the protective cover presses down the first support member 1, and then the first support member 1 presses down the elastic member 3, and the elastic member 3 produces elastic deformation, thereby achieving the effect of the snap-on mounting portion 22 of the second support member 2 being disengaged from the protective cover slot, and then the protective cover can be removed.

[0090] Embodiment 4

[0091] See also Fig.12 As shown, an embodiment of the present application provides a variable height contact rail support assembly, comprising: a first support member 1, a second support member 2 and an elastic member 3;

[0092] Among them, the first support member 1 and the second support member 2 are slidingly connected along the height direction, and an elastic member 3 is arranged between the first support member 1 and the second support member 2, one end of the elastic member 3 abuts against the first support member 1, and the other opposite end of the elastic member 3 abuts against the second support member 2; the second support member 2 is formed with a clamping installation groove 21 for clamping the contact rail; the second support member 2 is formed with a clamping installation portion 22 for clamping the protective cover.

[0093] Further, preferably, Figures 12 to 16As shown, a wing portion 13 is formed on the side of one end of the first supporting member 1, and an installation space is formed on the side of one end of the second supporting member 2. The wing portion 13 can be arranged in the installation space, and the wing portion 13 is arranged flush with the side of the second supporting member 2 to prevent the hook of the protective cover from being stuck in the gap between the first supporting member 1 and the second supporting member 2 along the height direction during disassembly;

[0094] The variable height contact rail support assembly also includes a connecting member 6 and a positioning member 7. The side wing portion 13 is formed with a mounting through hole, and the second support member 2 is formed with a waist-shaped hole 24 extending along its height direction. The connecting member 6 is inserted into the mounting through hole and the waist-shaped hole 24; the positioning member 7 is inserted into the partial structure of the connecting member 6 exposed from the first support member 1.

[0095] The connecting member 6 is preferably a pin, and correspondingly, the positioning member 7 is a cotter pin, which will be used as an example below.

[0096] It can be known from the above description that the connection member 6 and the positioning member 7 are mainly used to ensure that the first support member 1 and the second support member 2 are in a connected state to avoid separation of the two.

[0097] Furthermore, since the connecting member 6 can slide along the waist-shaped hole 24 and cooperate with the different compression amounts of the elastic member 3, it can adapt to protective covers of different heights.

[0098] Among them, preferably, Fig.15 As shown, two side wing portions 13 are provided at opposite ends of the first supporting member 1, and the two side wing portions 13 at each end are symmetrically arranged at opposite sides of the first supporting member 1, and correspondingly, each side wing portion 13 is equipped with the above-mentioned connecting member 6 and positioning member 7.

[0099] Further, preferably, Fig.12 , Fig.15 and Fig.16 As shown, the first support member 1 forms a limiting groove 14 (this limiting groove 14 is a circular groove, but is of course not limited to this), and the second support member 2 forms a limiting protrusion 26. One end of the elastic member 3 is clamped in the limiting groove 14, and the other end of the elastic member 3 is sleeved on the limiting protrusion 26, so that the spring is less likely to escape from between the first elastic member 3 and the second elastic member 3.

[0100] Further, preferably, Fig.12 As shown, there are two elastic components 3, and the two elastic components 3 are sequentially spaced apart along the length direction of the variable height contact rail support assembly.

[0101] The structures of the first supporting member 1 and the second supporting member 2 refer to the first embodiment, and will not be described in detail here.

[0102] In combination with the above structure, the operation of removing the protective cover by means of the variable height contact rail support assembly is as follows:

[0103] When the protective cover needs to be removed, the protective cover can be directly pressed down, and the protective cover presses down the first support member 1 (that is, the connecting member 6 can slide along the waist-shaped hole 24 at this time), and then the first support member 1 presses down the elastic member 3, and the elastic member 3 produces elastic deformation, so as to achieve the effect of the clamping installation part 22 of the second support member 2 being separated from the protective cover slot, and then the protective cover is removed.

[0104] It can be seen that the above operation is simple, convenient, time-saving and labor-saving, and avoids the problems that occurred in the previous barbaric construction, thereby playing a role in protecting the protective cover, etc. For other beneficial technical effects, please refer to Example 1, which will not be described in detail here.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
