[0028] Secondly, this utility model provides a vehicle including the wiring harness fixing device described above.

[0029] The wire harness fixing device and vehicle provided by this utility model, by setting at least one clamping body, the clamping body includes a first clamping part and a second clamping part, the first clamping part and the second clamping part are arranged opposite to each other to jointly enclose a clamping cavity for clamping the wire harness, thereby achieving a certain degree of regularity and fixation of the wire harness, and to a certain extent avoiding abnormal noise or interference between the wire harness and the vehicle body; at the same time, by connecting one end of the first clamping part to one end of the second clamping part, and forming a thinning wall at the connection between the one end of the first clamping part and the one end of the second clamping part, the clamping body is partially thinned, and the first clamping part is rotatably connected to the second clamping part through the thinning wall, thereby opening the clamping cavity to at least place the wire harness in the clamping cavity, or closing the clamping cavity to at least complete the clamping and fixing of the wire harness in the clamping cavity.

[0030] Because the first clamping part is rotatably connected to the second clamping part through a thinned wall, the rotational resistance between the first and second clamping parts can be reduced to a certain extent, thereby improving the flexibility and ease of operation of the first and second clamping parts. This facilitates the opening and closing of the clamping cavity. Compared to a wire harness fixing device that includes an annular fixing body with an opening on the fixing body communicating with the inner annular cavity of the fixing body, where external force is needed to increase the opening size to open the clamping cavity when the wire harness is clamped in the fixing body, allowing the wire harness to enter the clamping body through the opening, and then external force is needed again to reduce the opening size to be smaller than the outer diameter of the wire harness after the wire harness has entered, in order to close the clamping cavity and achieve the wire harness clamping and fixing solution, this utility model makes the opening and closing of the clamping cavity simple, thereby improving the convenience of clamping and fixing the wire harness in the clamping cavity, and thus improving the efficiency of wire management. Moreover, the thinned wall setting can also reduce the weight of the clamping body to a certain extent, ensuring that the clamping body reliably fixes the wire harness while also facilitating the lightweight design of the wire harness fixing device.

[0031] Meanwhile, by setting a locking structure on the clamping body, the locking structure can lock the first clamping part and the second clamping part when the clamping cavity is closed, thereby ensuring the reliable fixation of the wire harness by the clamping body to a certain extent, further avoiding the occurrence of abnormal noise and interference between the wire harness and the vehicle body, thereby further improving the wiring efficiency of the wire harness on the vehicle body and the assembly efficiency of the wire harness on the vehicle body.

Detailed Implementation

[0039] 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 skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0040] Vehicles include a body, which typically houses wiring harnesses used for signal transmission, etc. Related technologies usually incorporate wiring harness securing devices to organize and fix the harnesses, preventing noise and interference between the harnesses and the vehicle body. However, these wiring harness securing devices are relatively inefficient in terms of cable management.

[0041] Based on this, the present invention provides a wire harness fixing device and a vehicle. By configuring the clamping body to include a first clamping part and a second clamping part, one end of the first clamping part is connected to one end of the second clamping part, and a thinned wall is formed at the connection between the one end of the first clamping part and the one end of the second clamping part, so that the first clamping part is rotatably connected to the second clamping part through the thinned wall, so as to flexibly and conveniently open the clamping cavity to realize the wire harness insertion. Then, the first clamping part is rotated to close the clamping cavity, and the first clamping part and the second clamping part are locked by a locking structure to realize the clamping and fixing of the wire harness, thereby improving the wire management efficiency to a certain extent.

[0042] The wire harness fixing device and vehicle provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0043] Reference Figures 1 to 6 As shown, this embodiment provides a wire harness fixing device. This wire harness fixing device can be used, for example, to fix the wire harness at a location such as the body of a vehicle.

[0044] Specifically, the wire harness fixing device includes at least one clamping body 1, the clamping body 1 includes a first clamping part 11 and a second clamping part 12, the first clamping part 11 and the second clamping part 12 are arranged opposite to each other to jointly enclose and form a clamping cavity 10 for clamping the wire harness.

[0045] One end of the first clamping part 11 is connected to one end of the second clamping part 12, and a thinning wall 131 is formed at the connection between one end of the first clamping part 11 and one end of the second clamping part 12. The first clamping part 11 is rotatably connected to the second clamping part 12 through the thinning wall 131 to open or close the clamping cavity 10.

[0046] For example, refer to Figure 3 and Figure 5 As shown, a thinning groove 13 can be provided at the connection between one end of the first clamping part 11 and one end of the second clamping part 12. That is, a thinning design is performed at the connection between one end of the first clamping part 11 and one end of the second clamping part 12. In other words, the thickness at the connection between one end of the first clamping part 11 and one end of the second clamping part 12 is less than the thickness of the main body area of ​​the first clamping part 11 and the main body area of ​​the second clamping part 12, thereby forming the aforementioned thinning wall 131. For example, refer to... Figure 3As shown, the thickness d1 at the connection is 0.5 mm, and the thickness d2 of the main body area of ​​the first clamping part 11 is 1.51 mm.

[0047] Reference Figures 1 to 5 As shown, the clamping body 1 is provided with a locking structure 2, which is used to lock the first clamping part 11 and the second clamping part 12 when the clamping cavity 10 is closed.

[0048] For example, when fixing the wire harness, the clamping cavity 10 can be opened by rotating the first clamping part 11 relative to the second clamping part 12 through the thinning wall 131, allowing the wire harness to pass through the clamping cavity 10. Then, the first clamping part 11 can be rotated relative to the second clamping part 12 through the thinning wall 131 to close the clamping cavity 10. Then, the first clamping part 11 and the second clamping part 12 can be locked by the locking structure 2, thereby clamping and fixing the wire harness in the clamping cavity 10.

[0049] For example, the clamping body 1 can be made of nylon 66 (Polyhexamethylene Adipamide, abbreviated as PA66, also known as polyhexamethylene adipamide). Of course, the clamping body 1 can also be made of rubber, etc.

[0050] The wire harness fixing device provided in this embodiment provides at least one clamping body 1, which includes a first clamping part 11 and a second clamping part 12. The first clamping part 11 and the second clamping part 12 are arranged opposite to each other to form a clamping cavity 10 for clamping the wire harness. This can achieve the regularization and fixing of the wire harness to a certain extent, and avoid the occurrence of abnormal noise or interference between the wire harness and the vehicle body to a certain extent. At the same time, by connecting one end of the first clamping part 11 to one end of the second clamping part 12, and forming a thinning wall 131 at the connection between the first end of the first clamping part 11 and the second end of the second clamping part 12, the clamping body 1 is partially thinned. The first clamping part 11 is rotatably connected to the second clamping part 12 through the thinning wall 131. This allows the clamping cavity 10 to be opened to at least place the wire harness in the clamping cavity 10, or the clamping cavity 10 to be closed to at least complete the clamping and fixing of the wire harness in the clamping cavity 10.

[0051] Since the first clamping part 11 is rotatably connected to the second clamping part 12 through the thinned wall 131, the rotational resistance between the first clamping part 11 and the second clamping part 12 can be reduced to a certain extent. This improves the flexibility of rotation and the ease of operation of the first clamping part 11 and the second clamping part 12, making it easier to open or close the clamping cavity 10. Compared to making the wire harness fixing device include an annular fixing body with an opening on the fixing body that communicates with the inner annular cavity of the fixing body, when clamping the wire harness in the fixing body, external force is needed to increase the opening size to open the clamping cavity. The wire harness can enter the clamping body through the opening. After the wire harness enters, external force is used again to reduce the size of the opening to be smaller than the outer diameter of the wire harness in order to close the clamping cavity and achieve the solution of clamping and fixing the wire harness. This embodiment makes it easy to open and close the clamping cavity 10, thereby improving the convenience of clamping and fixing the wire harness in the clamping cavity 10 and thus improving the efficiency of wire management. Moreover, the thinning of the wall 131 can also reduce the weight of the clamping body 1 to a certain extent. While ensuring that the clamping body 1 can reliably fix the wire harness, it is also conducive to the lightweight design of the wire harness fixing device.

[0052] Meanwhile, by setting a locking structure on the clamping body, the locking structure can lock the first clamping part and the second clamping part when the clamping cavity is closed, thereby ensuring the reliable fixation of the wire harness by the clamping body to a certain extent, further avoiding the occurrence of abnormal noise and interference between the wire harness and the vehicle body, thereby further improving the wiring efficiency of the wire harness on the vehicle body and the assembly efficiency of the wire harness on the vehicle body.

[0053] In some embodiments, reference Figures 1 to 5 As shown, the side of the connection that is away from the clamping cavity 10 is recessed in the direction of the clamping cavity 10 to form a thinning groove 13, and the bottom wall of the thinning groove 13 is formed as at least a partially thinned wall 131.

[0054] This can improve the ease of rotation of the first clamping part 11 relative to the second clamping part 12 to a certain extent, thereby further improving the efficiency of cable management and the installation efficiency of the cable harness on the vehicle.

[0055] In some embodiments, reference Figures 1 to 5 As shown, the side of the connection near the clamping cavity 10 is recessed in the direction away from the clamping cavity 10 to form a thinning groove 13, and the bottom wall of the thinning groove 13 is formed as at least a partially thinned wall 131.

[0056] This design can improve the ease of rotation of the first clamping part 11 relative to the second clamping part 12 to a certain extent, thereby further improving the efficiency of cable management and the installation efficiency of the cable harness on the vehicle.

[0057] Furthermore, since the thinning groove 13 on the side of the connection facing the clamping cavity 10 is connected to the clamping cavity 10, it is possible to ensure that the first clamping part 11 can rotate relative to the second clamping part 12. When the clamping cavity 10 is closed, the thinning groove 13 can also serve as an extension space to accommodate part of the wire harness, which is beneficial to realize the relative expansion of the clamping cavity 10.

[0058] In some embodiments, reference Figures 1 to 5 As shown, the width of the thinning groove 13 gradually increases in the direction from the bottom of the thinning groove 13 to the opening of the thinning groove 13.

[0059] This design facilitates the rotation of the first clamping part 11 and reduces the stress at the thinning groove 13 to a certain extent, thus preventing breakage during rotation due to excessive stress at the connection between the first clamping part 11 and the second clamping part 12. Simultaneously, this design also improves the stability of the thinning groove 13, ensuring the stability of the connection between the first clamping part 11 and the second clamping part 12, facilitating stable clamping of the wire harness. Furthermore, this design increases the limit angle of rotation of the first clamping part 11 relative to the second clamping part 12, which is beneficial for improving wire management efficiency.

[0060] In some embodiments, the junction between the bottom wall and the side wall of the thinning groove 13 is smoothly transitioned. This can, to some extent, avoid stress concentration at the junction of the bottom wall and the side wall, thereby preventing breakage at the connection between the first clamping part 11 and the second clamping part 12, and providing good protection for the clamping body 1.

[0061] In some embodiments, reference Figures 1 to 5 As shown, the locking structure 2 includes a first engaging body 21 disposed at the other end of the first clamping part 11 and a second engaging body 22 disposed at the other end of the second clamping part 12, and the first engaging body 21 and the second engaging body 22 are engaged and connected.

[0062] This allows the other end of the first clamping part 11 to be connected to the other end of the second clamping part 12 without the need for a third-party medium or tool, thus improving the ease of connection. Furthermore, the engagement of the first locking body 21 and the second locking body 22 enables a detachable connection between the two, so that if either the clamping body 1 or the wire harness is damaged, only the damaged part needs to be replaced. This avoids the scrapping of the entire wire harness and clamping body 1 to a certain extent, and also facilitates the repair of the wire harness, thereby improving repair efficiency.

[0063] Of course, the other end of the first clamping part 11 and the other end of the second clamping part 12 can also be connected by magnetic attraction, bolts or other means.

[0064] In some embodiments, reference Figures 4 to 5 As shown, the second card assembly 22 includes a card slot, and the first card assembly 21 can extend into and engage with the card slot through the slot opening.

[0065] In this way, by directly inserting the first card assembly 21 into the card slot, the first card assembly 21 and the second card assembly 22 can be engaged. In addition, the card slot can also protect the first card assembly 21, thereby helping to improve the service life of the clamping body 1.

[0066] In some embodiments, reference Figures 4 to 5 As shown, the other end of the second clamping part 12 has a clamping arm 20. One end of the clamping arm 20 is connected to the second clamping part 12, and the other end of the clamping arm 20 extends in a direction away from the second clamping part 12 so as to define a slot together with the other end of the second clamping part 12.

[0067] This design allows the first clamping body 21 to engage or disengage within the slot simply by deforming the clamping arm 20. This facilitates the locking and unlocking of the first clamping part 11 and the second clamping part 12, thereby improving cable management efficiency. Furthermore, since the clamping arm 20 extends away from the second clamping part 12, meaning the slot is located outside the second clamping part 12, it does not affect the space within the clamping cavity 10. This ensures that while the first clamping body 21 engages with the slot, the clamping space within the clamping cavity 10 is adequately maintained, thus guaranteeing the clamping effect.

[0068] For example, when locking the first clamping part 11 and the second clamping part 12, the clamping arm 20 can be deformed in the direction away from the clamping cavity 10 to increase the width of the slot opening, so that the first clamping body 21 can be inserted into the slot. Then, by the inward rebound of the clamping arm 20, the first clamping body 21 can be clamped in the slot.

[0069] For example, when the first clamping part 11 and the second clamping part 12 are released from lock, the clamping arm 20 is deformed in the direction away from the clamping cavity 10 so that the width of the slot opening increases and the first clamping body 21 is moved out of the slot.

[0070] For example, in some embodiments, the clamping arm 20 and the second clamping part 12 can be integrally formed, which makes the structure of both high and helps to ensure the clamping effect, thereby achieving good locking of the first clamping part 11 and the second clamping part 12 and ensuring the stability of wire management; moreover, this also facilitates subsequent assembly and can improve the forming efficiency of the wire harness fixing device to a certain extent.

[0071] In some embodiments, reference Figures 4 to 5As shown, the width b of the slot opening is smaller than the width c of the slot's inner cavity.

[0072] Reference Figure 4 As shown, for example, the width b of the slot opening can be the width b along the left and right direction of the slot opening, and the width c of the inner cavity of the slot can be the width c of the inner cavity of the slot along the left and right direction.

[0073] In this way, the slot of the card slot enables the first card assembly 21 to be engaged and locked, thereby preventing the first card assembly 21 from coming out of the card slot to a certain extent, so as to ensure the reliable engagement of the first card assembly 21 and the second card assembly 22.

[0074] For example, the maximum width d of the first card assembly 21 (i.e., in Figure 4 In this design, the distance d) between the leftmost and rightmost sides of the first card assembly 21 can be 3.06 mm, and the width b at the opening of the card slot can be 1.57 mm, thereby preventing the first card assembly 21 from coming out of the opening of the card slot. For example, when the first card assembly 21 extends into the card slot, the interference fit between the first card assembly 21 and the opening of the card slot is 1.49 mm.

[0075] In some embodiments, reference Figures 4 to 5 As shown, the slot opening has a guide slope 221 for guiding the first snap-fit ​​body 21. The guide slope 221 extends inward at an inclination in the direction along which the first snap-fit ​​body 21 enters the slot.

[0076] This design facilitates the insertion of the first locking body 21 into the slot, enabling locking within the slot. This improves the locking efficiency and smoothness of the locking process, thereby enhancing cable management efficiency.

[0077] In some embodiments, reference Figure 4 As shown, the edge of the card slot is rounded. This rounded corner helps guide the first card assembly 21 as it is removed from the slot for unlocking, thus improving the unlocking efficiency of both the first and second card assemblies 21 and 22, facilitating maintenance and replacement. Furthermore, it prevents mutual wear between the first card assembly 21 and the card slot, providing good protection for both and extending the service life of the clamping body 1.

[0078] For example, the diameter of the circle containing the fillet can be 0.6 mm.

[0079] In some embodiments, reference Figure 4 As shown, the first locking body 21 is a locking protrusion, and the end of the locking protrusion has a rounded corner structure. (Refer to...) Figure 4As shown, the end here is specifically the bottom end of the latching protrusion. This rounded corner structure facilitates the insertion of the first latching body 21 into the latching groove, thereby improving cable management efficiency.

[0080] For example, the diameter of the circle containing the rounded corner structure can be 1.6 mm.

[0081] In some embodiments, the first clamping part 11 and the second clamping part 12 are integrally formed. This configuration eliminates the need for hinges or other third-party tools; the rotational connection of the first clamping part 11 and the second clamping part 12 can be achieved simply by thinning the groove 13, simplifying the structure of the clamping body 1. Furthermore, the integral forming of the first clamping part 11 and the second clamping part 12 results in high overall structural strength, which is beneficial for ensuring cable management stability and facilitates subsequent assembly.

[0082] Of course, in other embodiments, one end of the first clamping part 11 and one end of the second clamping part 12 can also be fixed by means of adhesive bonding, welding or other methods.

[0083] In some embodiments, reference Figure 1 and Figure 6 As shown, the clamping body 1 also includes an extension protrusion 14 disposed on one axial side of the first clamping part 11 and / or the second clamping part 12, the extension protrusion 14 extending toward a direction away from the clamping cavity 10.

[0084] For example, refer to Figure 1 and Figure 6 As shown, an extending protrusion 14 can be provided at the axial end of the second clamping part 12. For example, there can be three clamping bodies 1, and the second clamping part 12 can be provided along the axial direction in one of the clamping bodies 1. Figure 6 An extension protrusion 14 is provided at the upper end, and in one of the other clamping bodies 1, the second clamping part 12 extends along... Figure 6 An extension protrusion 14 is provided at the lower end. Of course, an extension protrusion 14 may also be provided on the first clamping part 11.

[0085] This design provides a degree of protection for the wire harness within the clamping cavity 10 through the extended protrusion 14. Furthermore, it guides the direction of the wire harness, ensuring its neatness. Additionally, it allows for the use of tape or rope to secure the wire harness to the extended protrusion 14, preventing it from shifting on the clamping body 1 and further enhancing its stability.

[0086] For example, the extension protrusion 14 can be integrally formed with the second clamping portion 12.

[0087] For example, the extended protrusion 14 along Figure 6 The dimension w1 in the vertical direction shown can be 20mm, and the extended protrusion 14 extends along... Figure 6 The left-right direction L3 can be 11.74mm, and the thickness of the extended protrusion 14 can be 1.5mm.

[0088] In some embodiments, reference Figure 5 As shown, the first clamping part 11 is provided with a gripping part 111. This can improve the ease of rotation of the first clamping part 11 relative to the second clamping part 12 to a certain extent, thereby improving cable management efficiency. Moreover, the gripping part 111 can also facilitate the locking of the first clamping part 11 and the second clamping part 12 through the locking structure 2, with high locking efficiency.

[0089] In some embodiments, reference Figure 5 As shown, one end of the gripping part 111 is connected to the first clamping part 11, and the other end of the gripping part 111 extends in a direction away from the first clamping part 11 to form a free end for gripping.

[0090] This makes it easy to shape the grip part 111 and convenient for users to hold and operate, thereby improving cable management efficiency.

[0091] Of course, the gripping part 111 can also be a gripping groove or the like provided on the clamping body 1.

[0092] In some embodiments, reference Figure 5 As shown, the gripping part 111 is positioned near the other end of the first clamping part 11. This makes it easier to rotate the first clamping part 11 relative to the second clamping part 12 by pulling it through the thinned wall 131, thus enabling convenient rotation of the first clamping part 11 and making it more convenient to use.

[0093] In some embodiments, reference Figures 1 to 2 As shown, there are at least two clamping bodies 1. This arrangement allows for the organization of different numbers of wire harnesses through each clamping body 1, making the wire harness fixing device highly flexible and expanding its applicability.

[0094] In some embodiments, reference Figures 1 to 2 As shown, at least two clamping bodies 1 are arranged along a circumference, and adjacent clamping bodies 1 are connected by a second clamping part 12. That is, the second clamping parts 12 of adjacent clamping bodies 1 are connected.

[0095] By arranging the clamping bodies 1 in the manner described above, the space occupied by all clamping bodies 1 can be reduced to a certain extent, improving the compactness of the clamping bodies 1 and thus improving the compactness of cable management. This allows the cable harness fixing device to be used in scenarios where cable harnesses are fixed in narrow spaces, and further avoids abnormal noises or interference between the cable harness and the vehicle body. Moreover, compared to using two or more cable harness fixing devices to fix at least two cable harnesses, this arrangement can fix at least two cable harnesses with a single cable harness fixing device while ensuring the fixation of each cable harness, thereby improving the fixing efficiency of the cable harness to a certain extent.

[0096] For example, the clamping body 1 can be three. The wiring harness fixing device can be applied in the PMA pure electric module architecture. In the PMA platform, there is a channel on the sheet metal of the vehicle body. The space in the channel is narrow and three wiring harnesses need to pass through. At this time, the wiring harness fixing device can fix the three wiring harnesses separately.

[0097] In some embodiments, reference Figures 1 to 2 As shown, the wire harness fixing device also includes a fixing structure 3 connected to the clamping body 1. The fixing structure 3 includes at least two fixing parts 31, each fixing part 31 being used to fix the clamping body 1 in a preset position.

[0098] In this way, the clamping body 1 can be fixed at a preset position by the fixing part 31. Before wiring, the clamping body 1 can be pre-connected to the vehicle body by the fixing part 31, which facilitates the subsequent use of the wire harness fixing device. At the same time, after the clamping body 1 has clamped the wire harness, the fixing part 31 can fix the clamping body 1 to the vehicle body, thereby further securing the wire harness to the vehicle body and further preventing abnormal noise or interference between the wire harness and the vehicle body. Moreover, the fixing part 31 at least two times can achieve a good fixation of the clamping body 1, which to a certain extent prevents the clamping body 1 from rotating accidentally under force, further ensuring the fixing effect of the wire harness on the vehicle body.

[0099] For example, the fixing part 31 can be a fixing buckle with a locking hole at a preset position, and the fixing buckle can be inserted into and engaged in the locking hole.

[0100] Of course, the fixing part 31 can also be a fixing bolt, which can be used to fix the clamping body 1 at a preset position.

[0101] In some embodiments, reference Figures 1 to 6 As shown, the fixing structure 3 also includes at least two fixing arms 32, each fixing arm 32 having at least one fixing part 31.

[0102] In this way, the clamping body 1 is well fixed by the fixing arm 32, ensuring the stability of the wire harness.

[0103] In some embodiments, reference Figures 1 to 6 As shown, at least two fixing arms 32 are respectively disposed on opposite sides of the clamping body 1. This can improve the reliable fixation of the clamping body 1 to a certain extent, ensure the fixing effect of the clamping body 1 on the vehicle body, and thus further improve the stability of the wiring harness.

[0104] For example, refer to Figure 1 and Figure 2 As shown, there can be three clamping bodies 1, for example, one clamping body 1 can be set at the top and two clamping bodies 1 can be set at the bottom. For example, there can be two fixing arms 32, and one fixing arm 32 can be set on the left and right sides of the clamping body 1 respectively.

[0105] For example, the entire wire harness fixing device along Figure 2 and Figure 6 The total length L in the left and right directions shown is 130mm, along... Figure 2 The height h in the vertical direction shown is 42.45 mm, along... Figure 6 The dimension w2 in the vertical direction shown is 56mm.

[0106] For example, refer to Figure 2 As shown, the center distance L1 between the two fixing parts 31 on the fixing arm 32 is 100mm.

[0107] In some embodiments, reference Figures 1 to 2 As shown, the fixing arm 32 is provided with a weight reduction hole 321. This ensures reliable fixation of the clamping body 1 while reducing the weight of the fixing arm 32 to a certain extent, which is conducive to achieving a lightweight design of the entire wire harness fixing device.

[0108] In practice, reinforcing ribs can be installed inside the weight reduction hole 321 to ensure the structural strength of the fixing arm 32 and ensure the wire harness management effect.

[0109] This embodiment also provides a vehicle, including a wiring harness fixing device.
